Abstract
The utility model discloses a novel artificial fish reef. The artificial fish reef can be used for arranging on seabed. A facing stream face and a back stream face are arranged on the two sides of the artificial fish reef top relatively. The top of the facing stream face and the top of the back stream face are face to the center of the novel artificial fish reef obliquely and a reversed V shape can be presented. The facing stream face and the back stream face are arranged in a reversed V shape relatively on the top of the artificial fish reef. The facing stream face can produce upwelling and can deliver bottom nutritive salts upward in a tide-failing period. Primary productivity of local sea area can be improved so that baits can be brought to fish. Situation is similar when the tide rises. The facing stream face can produce the upwelling and low-rate back eddy can be produced around the back stream surface. Space can be formed, wherein the space is suitable for inhabiting and breeding of the fish so as to achieve similar ecological effects of a large fish reef. The survival and breeding condition of the fish in a whole sea area can be improved as a large number of the novel artificial fish reefs are arranged in 'a fish reef field' manner in wide sea area.
Description
Technical field
The utility model relates to the fish shelter technical field, particularly a kind of novel artificial fish shelter.
Background technology
Because now project of cultivation is more and more, so that calacove, the marine organisms such as the marine wetland, coastal wetland space of perching of relying is fewer and feweri, and therefore building in a large number artificial fish shelter at exposed waters seems extremely important.
The general ocean current flow velocity of exposed waters is relatively large, is unfavorable for that fish perch breeding.Can reduce local velocity and build artificial fish shelter, form the back of the body eddy current of low flow velocity at the fish shelter back side, form and be suitable for the space that fish perch breeding, progressively develop into the spawning ground of fish.
The at present general artificial fish shelter modes of scrapping the heavy sea of ship that adopt more, because this type of artificial fish shelter enormous size, therefore more stable in the seabed, exactly because but also enormous size (sink to the bottom of the sea and be similar to a submerged reef), therefore can affect the ship navigation, cause traffic safety hidden danger.
Therefore, how to provide a kind of small-sized artificial fish shelter, be applicable to the larger exposed waters of flow velocity, reach the similar ecological effect of large-scale fish shelter, become the important technological problems that those skilled in the art need to be resolved hurrily.
The utility model content
In view of this, the utility model provides a kind of novel artificial fish shelter, is applicable to the larger exposed waters of flow velocity, can produce upwelling at the fluoran stream surface of fish shelter, the nutritive salt of bottom is upwards carried, improved the primary productivity in local marine site, reach the similar ecological effect of large-scale fish shelter.
For achieving the above object, the utility model provides following technical scheme:
A kind of novel artificial fish shelter, be used for being arranged on sea bed, the both sides, top of the artificial fish shelter that this is novel are relatively set with fluoran stream surface and lee side, and the top of described fluoran stream surface and described lee side all tilts towards the center of described novel artificial fish shelter, present the splayed structure.
Preferably, described fluoran stream surface and described lee side with the angle of the top planes of described novel artificial fish shelter between 30 ~ 60 °.
Preferably, the agent structure of described novel artificial fish shelter adopts xoncrete structure.
Preferably, between described lee side and described fluoran stream surface, be laid with the nylon etting.
Preferably, described nylon etting is fixed by rivet.
Can find out from above-mentioned technical scheme, the novel artificial fish shelter that the utility model provides, its both sides, top are relatively set with fluoran stream surface and the lee side that presents the splayed structure, in the ebb current period, fluoran stream surface produces upwelling, the nutritive salt of bottom is upwards carried, improved the primary productivity in local marine site, and then bring bait to fish; Flood tide, and situation is similar, produces upwelling at the ebb tide fluoran stream surface, and near lee side, forms the back of the body eddy current of low flow velocity, forms and is suitable for the space that fish perch breeding, reaches the similar ecological effect of large-scale fish shelter.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the novel artificial fish shelter that Fig. 1 provides for the utility model embodiment;
The numerical simulation ebb current design sketch of the novel artificial fish shelter that Fig. 2 provides for the utility model embodiment;
The numerical simulation flood current design sketch of the novel artificial fish shelter that Fig. 3 provides for the utility model embodiment.
Wherein, 1 is fluoran stream surface or lee side, and 2 is the nylon etting, and 3 is rivet, and 20 for perching and breeding area, and 41 is the ebb tide upwelling, and 42 perch the district for ebb tide, 51 upwellings that are that flood tide, and 52 perch the district for flood tide.
Embodiment
The utility model discloses a kind of novel artificial fish shelter, be applicable to the larger exposed waters of flow velocity, can produce upwelling at the fluoran stream surface of fish shelter, the nutritive salt of bottom is upwards carried, improve the primary productivity in local marine site, reach the similar ecological effect of large-scale fish shelter.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1, the structural representation of the novel artificial fish shelter that Fig. 1 provides for the utility model embodiment.
The novel artificial fish shelter that the utility model embodiment provides, be used for being arranged on sea bed, its core improvement is, the both sides, top of the artificial fish shelter that this is novel are relatively set with fluoran stream surface and lee side, and the top of fluoran stream surface and lee side all tilts towards the center of novel artificial fish shelter, presents the splayed structure, and the structure of the artificial fish shelter that this is novel as shown in Figure 1, wherein 1 is fluoran stream surface or lee side, according to the installation site and flood tide or the ebb tide situation decide.
Can find out from above-mentioned technical scheme, the novel artificial fish shelter that the utility model embodiment provides, its both sides, top are relatively set with fluoran stream surface and the lee side that presents the splayed structure, in the ebb current period as shown in Figure 2, be subject to the impact of ebb tide upwelling 41 from left to right, the fluoran stream surface in left side produces upwelling, and the nutritive salt of bottom is upwards carried, improve the primary productivity in local marine site, and then bring bait to fish; Flood tide, and situation is similar, as shown in Figure 3, is subject to the impact of the rising tide upwelling 51 of right-to-left, and the fluoran stream surface on right side produces upwelling; And near the lee side of opposite side, form the back of the body eddy current of low flow velocity, and form and be suitable for the space that fish perch breeding, namely the ebb tide among Fig. 2 and Fig. 3 is perched district 42 and is perched district 52 with flood tide, reaches the similar ecological effect of large-scale fish shelter.
