Description

A seaweed reef with the function of protecting seedlings

technical field

The invention belongs to the field of attached seedlings and multiplication of marine algae seedlings, and in particular relates to a seaweed reef with the function of protecting seedlings.

Background technique

Seaweed farms are an important part of the marine ecosystem. The seaweed farms supported by large algae have high primary productivity. At the same time, the grown seaweed forms a complex animal and plant food web, which can enrich eutrophic salts such as N and P, and restrain The outbreak of "red tide" absorbs heavy metal ions and protects the marine environment. The economic value created by seaweed farms is great. Seaweed itself has industrial, edible and medical value. Seaweed farms also provide places for fish to seek bait, avoid enemies, and lay eggs. At present in my country, algae such as Sargassum are the main supporting plants of coastal seaweed farms. However, with the impact of objective factors such as global climate change, the number of seaweed farms is decreasing, and seaweed biodiversity is also declining. In the world, there have been some achievements in the restoration of seaweed farms. The main countermeasures are the establishment of nature reserves to reduce the damage of human activities; research on artificial reproduction biology and related work, such as indoor artificial seedling cultivation and intermediate cultivation of seedlings, etc. . The intermediate cultivation of seedlings includes indoor cultivation, pond cultivation and raft cultivation in sea area. Seedling attachment bases include stones, oyster shells, cement flakes, cloth curtains, vinylon rope curtains, bamboo, wood chips, etc. Among them, stone and cement flakes have the best adhesion fastness. When artificially raising seedlings, more mature seed algae are collected in the laboratory to discharge sperm and eggs, zygote germination, attach to the fixation base, and grow seedlings. However, on attachment bases such as shells and rocks, although young sporophytes and seedlings adhere well, it is not easy to put them in seawater for propagation. If the seedlings are made of nylon ropes and hung on the sea surface, the seedlings will be easily eaten and damaged by various fish in the seaweed field. It is difficult for the seedlings to ensure the robust growth in the early stage or even be severely damaged, which will easily lead to slow reproduction. and low reproductive rate; a large number of seaweeds are scattered and propagated, and protection measures are difficult to put in place, and management, observation and monitoring are very inconvenient; moreover, although artificial or semi-artificial seaweed farms are generally selected in the offshore, the water depth is not deep, generally about tens of meters to More than 100 meters away, the environment is not as complex and changeable as the middle sea and deep sea. The wind and waves are usually small and the destructive power is limited. destroy.

Contents of the invention

The purpose of the present invention is to overcome the lack of initial protection for seaweed seedlings and seaweeds in the prior art when seaweeds are propagated in seaweed farms, resulting in low seaweed reproduction rate; poor reproduction concentration, inconvenient monitoring and management; and poor ability to resist strong wind and waves , cannot effectively protect seaweed and other problems, and provides a kind of algae that can effectively carry out concentrated release of seaweed seedlings, has good protection effect, can concentrate reproduction, and has a reasonable growth environment for seaweed, and can effectively protect and preserve seaweed when strong winds and waves invade. reef.

In order to achieve the above object, the present invention adopts the following technical solutions:

A seaweed reef with the function of protecting seedlings, including a whole frame, a floating body on the sea surface, and a recovery cable. The whole frame has an upward main opening, and several brick grooves are arranged on the whole frame. The brick grooves The notch faces the outside of the whole frame, and the brick groove is provided with algae bricks with seaweed seedlings attached, and the bottom of the brick groove is provided with a seedling accommodating hole, and the seedling accommodating hole penetrates the inner surface of the whole frame With the bottom of the brick groove, the seedlings on the algae bricks are attached to the surface of the algae bricks facing the inside of the whole frame. The algae bricks are provided with brick cables. The main center column outside the opening, the upper end of the main center column is connected to the floating body on the sea surface, one end of the recovery cable is fixed on the coast, and the other end is connected to the main center column, and the recovery cable is in a relaxed state. The main center column is provided with several tension bodies, and the brick cable is connected to one of all the tension bodies. The brick cable is in a tensioned state, and each brick cable is There is a section wound on the tensioning body connected to itself. The tensioning body is a set of rotating drums arranged on the main center column and rotatably connected with the main center column. The tensioning body is fixed by The components are fixed on the main center column, the rotating cylinders are stacked one after another, the lower end of the lowest rotating cylinder contacts the limit neck on the main center column, the whole frame is provided with several counterweights, and the matching The weight is connected to the edge of the upper end of the whole frame through the counterweight connecting rope. The sea surface floating body floats on the sea surface by the buoyancy force received, and the sea surface floating body provides pulling force for the whole frame, so that the whole frame can also keep in the sea water without sinking, thus providing a centralized delivery space for algae bricks. After the algae bricks have cultivated the seaweed seedlings, the seaweed seedlings are attached to the algae bricks, and the algae bricks are located in the brick grooves, and are tightened and fixed by the brick drag cables. The seaweed seedlings face inside the whole frame, so in the initial stage of seedling growth, all the seaweeds are within the inner range of the whole frame, with only one upward main opening of the whole frame itself, so the seedlings are not only concentrated, but also effectively For protection, it is difficult for fish to eat these seedlings in large quantities, and the growth status of seedlings can also be monitored conveniently due to concentrated feeding. Through observation, it is found that after the seedlings grow for a certain period of time, the seaweed begins to fill the inside of the whole frame. At this time, the fixing parts can be removed. Since the brick cable is wound on the rotating drum, and the brick cable is in a tensioned state, Therefore, the rotating drum will be pulled and rotated, and the brick cable will be released. The brick cable will stretch and elongate, and the algae brick will leave the brick groove with a part of the seaweed that is connected to the brick body, and will be released to a certain distance from the whole frame. At this time, the seaweed can obtain a better growth space and environment. At this time, because the seaweed has grown to a certain extent, the ability to resist the impact and damage of fish and seawater is no longer as weak as the seedling stage. Therefore, the seaweed Yield and subsequent multiplication ability can be guaranteed. Moreover, due to the existence of counterweights, the weight distribution on the outside of the whole frame can be balanced. When the whole frame is driven by seawater currents, it can have greater static inertia, preventing the whole frame from tilting too much due to the ups and downs of seawater and preventing The whole frame moves too fast in sea water.

Preferably, the algae brick is in the shape of a hexagonal column or a cube.

Preferably, it also includes several built-in ropes, and the algae brick is provided with at least one brick inner hole that runs through its two side walls, any one built-in rope passes through at least five brick inner holes, and the two built-in ropes The ends are respectively connected to two algae bricks among all the algae bricks that it passes through. When the brick cable is released, the algae bricks leave the brick groove, showing a tendency to expand, and the correlation between them decreases, and they are all independent individuals. At this time, the built-in rope can connect multiple algae bricks together to improve connectivity, prevent a single algae brick from excessive deviation, make the overall structure more balanced, and maintain a good and reasonable seaweed growth space and layout. Moreover, when all the zippers of the bricks are released, the built-in ropes are criss-crossed, which is equivalent to forming a net-like structure. In addition to improving the stability of each algae brick, it can also continue to play the role of a protective net, so that algae protected during subsequent growth.

Preferably, the depth of the brick groove is between one-third and one-half of the thickness of the algae brick. If the depth of the brick groove is too large, the algae brick will not be easily separated from the whole frame when necessary. If it is too small, the positioning of the algae brick will be difficult. Therefore, a reasonable choice is required. Generally, the depth of the brick groove is designed to be between one-third of the thickness of the algae brick. between one-half.

Preferably, at least two balancing cables are arranged on the main center column, and each balancing cable is connected to an auxiliary floating ball floating on the sea surface. Although the auxiliary floating ball alone is not enough to pull the whole frame, but the auxiliary floating ball can be used to provide a part of the buoyancy, so that the pulling force of the whole frame is not only supported by one point, but multiple points simultaneously pull the whole frame, so that the whole frame is in seawater It can be more stable and provide a better growth and protection environment for seaweed.

As a preference, the sea surface floating body includes an inflatable part, and the sea surface floating body is provided with an anti-big wave structure. The anti-big wave structure includes a built-in tube with a closed lower end. The push plate spring connected to the lower closed end of the push plate spring, the upper end of the push plate spring is provided with a main push plate that is mutually sealed with the inner tube wall of the built-in tube, and the main center column passes through the lower closed end of the built-in tube. The connection between the floating body on the sea surface and the main center column is the lower part of the main push plate, the built-in tube is provided with an upper sealing part, and the upper part of the built-in tube is provided with an inner air port communicating with the inflatable part, and the inner air port is closed through the upper The inner air pipeline in the part is connected to the outer air port, the outer air port is provided with a one-way valve, and the inner air pipeline is divided into two sections of independent pipelines that are not connected by a valve core, and the valve core is provided with There is a core channel that can connect two independent pipelines. The position of the core channel is lower than that of the independent pipelines. The upper end of the valve core is connected to the built-in tube through a lanyard. The gap between the valve core and the upper sealing part is Slidingly connected, the side wall of the spool and the upper sealing part are mutually sealed. Occasionally, when a big storm is struck, the present invention will also rise and fall with the storm. When the big waves rise, the floating body on the sea surface and the whole frame rise almost at the same time. The frame is relatively close to the floating body on the sea surface and the distance is relatively large. The main center column overcomes the tension of the push plate spring, pushes the main push plate to move a large distance, and pushes up the valve core. The core channel on the valve core connects the inner air pipe, and the sea surface floats The gas in the body begins to be released from the one-way valve, and the buoyancy begins to decrease. When the whole frame and the floating body on the sea surface rise again, the inner air pipe is disconnected again. The buoyancy of the rig is no longer enough to pull the whole frame, and the whole frame starts to sink for a certain distance until the recovery cable is pulled tight, or the length of the recovery cable is long enough, and the whole frame directly sinks to the seabed of the seaweed field. On the sea surface, the place with the largest wind and waves is generally on the sea surface or near the sea surface, and along the sea surface, the deeper the position, the smaller the wind and waves are, so after the entire frame sinks, the surrounding area will be less affected by the strong wind and waves Therefore, the algae growing on the surrounding algae bricks will not be damaged too much by the strong wind and waves, and can be well preserved, so as to realize self-avoidance and self-protection when dealing with strong wind and waves. After the big storm has passed, the whole frame can be pulled back by recycling, and a sea surface floating body can be updated, so that the seaweed can continue to grow and proliferate well.

As a preference, a core-receiving groove is provided above the built-in tube, and a core clip that can engage with the core-receiving groove is provided on the valve core, and the core clip is outside the core-receiving groove and faces Core slot. The core card head can be snapped into the core receiving groove to position the valve core, so that the inner air pipe is always connected, and the air can be quickly deflated, so that the whole frame can sink as soon as possible to avoid big wind and waves.

The beneficial effects of the present invention are: it is possible to carry out centralized feeding of seaweed seedlings, which is convenient for monitoring and observation; through the cooperation of algae bricks, brick grooves and whole frames, the initial protection of seedlings is realized, the survival rate is improved, and the subsequent multiplication effect is ensured; The anti-big wave structure can allow the whole frame to sink automatically with seaweed when the storm hits, avoiding the storm, reducing the loss of seaweed damage, and protecting the seaweed well; the whole frame is connected and fixed by a recovery cable To the coast, it will not float out with the sea water, and the control degree is good. At the same time, the recovery cable is also a structure for recovering seaweed and the whole rack, which is conducive to the harvest of grown seaweed and the reuse of the whole rack.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Embodiment 1: a kind of seaweed reef with seedling protection function as shown in Fig. 1, Fig. 2, Fig. 3, Fig. 5, comprises whole frame 1, sea surface floating body 2, recovery cable 3, and described whole frame 1 has a The main opening facing upwards, the whole frame 1 is provided with several brick grooves 11, the notches of the brick grooves 11 face the outside of the whole frame 1, and the algae bricks with seaweed seedlings attached to them are arranged in the brick grooves 11 12. The bottom of the brick groove 11 is provided with a seedling accommodating hole 13, and the seedling accommodating hole 13 runs through the inner surface of the whole frame 1 and the bottom of the brick groove 11, and the seedlings on the algae brick 12 are attached to the algae brick 12 On the surface facing the inside of the whole frame 1, the algae brick 12 is provided with a brick cable 14, and the whole frame 1 is provided with a main center column 4 whose upper end extends out of the main opening of the whole frame 1, so The upper end of the main center column 4 is connected to the sea surface floating body 2, one end of the recovery cable 3 is fixed on the coast, and the other end is connected to the main center column 4, and the recovery cable 3 is in a relaxed state. The central column 4 is provided with several tensioning bodies 41, and the described brick dragline 14 is connected to one of all the tensioning bodies 41, and the described brick dragline 14 is in a tensioned state, and each brick pulls The cable 14 has a section wound on the tension body 41 connected to itself, and the tension body 41 is a set of drums that are arranged on the main center column 4 and can be rotatably connected with the main center column 4. The tension body 41 mentioned above is fixed on the main center column 4 through a fixing piece, the rotating cylinders are stacked one after another, the lower end of the lowest rotating cylinder contacts the stop neck 42 on the main center column 4, and the whole rack 1 Several counterweights 7 are arranged on the top, and the counterweights 7 are connected to the edge of the upper end of the whole frame 1 through counterweight connecting ropes 71 . The algae brick 12 is hexagonal or square. It also includes a number of built-in ropes 5. The algae brick 12 is provided with at least one brick inner hole that runs through its two side walls. Any built-in rope 5 passes through at least five brick inner holes. The two ends are respectively connected to two algae bricks 12 in all the algae bricks 12 passed by itself. The depth of the brick groove 11 is between one-third and one-half of the thickness of the algae brick 12 . The main center column 4 is provided with at least two balance cables 43, and each balance cable 43 is connected to an auxiliary floating ball 6 floating on the sea surface.

The principle of the floating body 2 on the sea surface is like the inflatable floating ball in daily life, and a large amount of compressed gas can be filled therein to obtain greater buoyancy, especially in water. The sea surface floating body 2 floats on the sea surface by the buoyancy force received, and the sea surface floating body 2 provides pulling force for the whole frame 1, so that the whole frame 1 can also keep in the seawater without sinking, thereby providing a centralized delivery space for the algae bricks 12. After the algae brick 12 has cultivated the seaweed seedling, the seaweed seedling is attached on the algae brick 12, and the algae brick 12 is in the brick groove 11, and is tightened and fixed by the brick dragline 14. The seaweed seedlings face into the whole frame 1, so in the early stage of seedling growth, all the seaweeds are within the inner range of the whole frame 1, and only have one upward main opening of the whole frame 1 itself, so the seedlings are not only concentrated, but also get Without effective protection, it is difficult for fish to eat these seedlings in large quantities, and the seedlings can also be easily monitored for their growth status due to concentrated feeding. And by observing, it is found that after the seedlings grow for a certain period of time, the seaweed begins to fill the inside of the whole frame 1. At this time, the fixing parts can be unloaded. Tight state, so the rotating drum can be pulled and rotated, releasing the brick dragline 14. Of course, in this design, the winding directions of the brick cables 14 connected to the same drum must be the same, both clockwise or counterclockwise, otherwise the meaning of winding the brick cables 14 will be lost . After the brick cable 14 is stretched and elongated, the algae brick 12 breaks away from the brick groove 11 with a part of the algae growing on its own brick body, and is released to a position with a certain length from the whole frame 1. At this time, it is released The part of the seaweed can get a better growth space and environment. At this time, because the separated seaweed has grown to a certain extent, the ability to resist the impact and damage of fish and seawater is no longer as weak as that of the seedling stage, so the production of seaweed and subsequent proliferation can be guaranteed. And in the above-mentioned process, the release of brick stay cable 14 can be carried out by dividing into periods of time and in batches. When the space in the main frame is not enough, you can first remove the fixing parts on a rotating drum, let a part of the algae bricks 12 be separated, as shown in Figure 4, and then continue to let it proliferate for a while, until the space in the main frame is observed. When it is not enough, continue to release the fixing parts on other drums, and follow this step for many times until all algae bricks 12 are separated and released. The fixing parts in the above content can be any commonly used fixing and connecting devices such as bolts, fixing ropes, pins, etc., as long as they can fix the drum and the main center column 4 . After the brick cable 14 is released and elongated, the algae brick 12 leaves the brick groove 11, showing a tendency to expand, and the correlation between them is reduced, and they are all independent individuals. At this time, the built-in rope 5 can connect a plurality of algae bricks 12 together, improve connectivity, prevent a single algae brick 12 from excessively shifting, make the overall structure more balanced, and maintain a good and reasonable seaweed growth space and layout. Moreover, after all the brick slide locks are released, each built-in rope 5 is criss-crossed, which is equivalent to forming a similar net-like structure. In addition to improving the stability of each algae brick 12, it can also continue to play the role of a protective net. Let the algae continue to be reasonably protected during the subsequent growth process.

Embodiment 2: The basic structure and implementation of this embodiment are the same as in Embodiment 1, the difference is that, as shown in Figure 6 and Figure 7: the sea surface floating body 2 includes an inflatable part 21, and the sea surface floating body 2 is provided with an anti-big wave structure. The anti-big wave structure includes a built-in tube 22 with a closed lower end. The lower part of the built-in tube 22 is provided with a push plate spring 23 connected to the lower closed end of the built-in tube 22. The upper end of the push plate spring 23 is provided with the main push plate 231 which is mutually sealed with the inner tube wall of the built-in pipe 22. The main center column 4 passes through the lower closed end of the built-in pipe 22, and the sea surface floating body 2 is connected to the main center. The connection of the column 4 is the lower part of the main push plate 231, and the upper sealing part is arranged inside the built-in tube 22, and the inner gas port 211 communicated with the inflatable part 21 is arranged on the upper part of the built-in tube 22, and the inner gas port 211 The inner air pipe 25 in the upper sealing part is connected to the outer air port, the outer air port is provided with a one-way valve 24, and the inner air pipe 25 is separated by a valve core 26 into two separate independent pipes, The valve core 26 is provided with a core channel 261 that can connect two independent pipelines, the position of the core channel 261 is lower than the independent pipeline, and the upper end of the valve core 26 is connected to the built-in tube 22 through a lanyard 27 Above, the valve core 26 is slidingly connected with the upper closing part, and the side wall of the valve core 26 and the upper closing part are mutually sealed. The top of the built-in tube 22 is provided with a core receiving groove 28, and the valve core 26 is provided with a core chuck 29 that can engage with the core receiving groove 28, and the core chuck 29 is located in the core receiving groove. 28 outside and towards the core receiving groove 28.

Artificial or semi-artificial seaweed farms are generally located near the sea, and the water depth is not deep, generally about tens of meters to more than a hundred meters. The environment is not as complex and changeable as the middle sea and deep sea, and the wind and waves are usually small and the destructive power is limited. But when once in a while there is a big storm to hit, the present invention also can rise and fall greatly along with the storm. When the big waves rise, the floating body on the sea surface and the whole frame 1 rise almost at the same time. Therefore, the whole frame 1 is relatively close to the floating body on the sea surface, and the main center column 4 pushes the main push plate 231 to move up a large distance, and the valve core 26 is pushed up, and the core clip 29 is stuck in the core receiving groove 28, and the valve core 26 After being fixed, the core channel 261 on the valve core 26 connects the inner air pipe, the gas in the floating body on the sea surface starts to be released from the one-way valve 24, and the buoyancy begins to decrease until it is not enough to pull the whole frame 1, and the whole frame 1 sinks A certain distance, until the recovery cable 3 is tensioned, or the length of the recovery cable 3 is long enough, the whole frame 1 directly sinks to the seabed of the seaweed field. On the sea surface, the place with the greatest wind and waves is generally the sea surface or a place close to the sea surface, and along the sea surface, the deeper the position, the smaller the wind and waves are, so after the entire aircraft 1 sinks, the surrounding area will be greatly affected by the strong wind and waves. Smaller, so the algae growing on its surrounding algae bricks 12 will not be damaged too much by the big wind and waves, and can be well preserved, so as to realize self-avoidance and self-protection when dealing with big wind and waves. After the big storm passed, the whole frame 1 could be pulled back by recycling, and a sea surface floating body 2 could be updated, so that the seaweed could continue to grow and proliferate well. The realization of the above-mentioned process is based on the premise of strong wind and waves. If it is only a small wind and a small wave at ordinary times, although the main push plate 231 will also move up and down, the force provided by the sea waves to make the main push plate 231 and the valve core relatively close is insufficient. The main push plate 231 has not had time to contact and push the spool 26 in the future, and it has moved downward under the tension of the push plate spring 23 to reset. After resetting, the push plate spring 23 returns to the compressed state. And only when the wind and waves are very big, the speed of the relative motion between the whole frame 1 and the sea surface floating body 2 is fast enough, and the force of the main center column 4 is large enough, the upper force of the main center column 4 to the main push plate 231 is enough to overcome the pushing force. The pulling force of the plate spring 23 drives the main push plate 231 to push the spool 26 up to realize the deflation of the floating body 2 on the sea surface.
