Description

  The present invention relates to a fish tank having a drainage function.

  The breeding of seafood in aquariums is popular because it is easy to breed and looks good as an interior. In addition, a young woman for various reasons such as “Beta,” a freshwater fish that has a long and beautifully colored tail fin and dorsal fin, is healed in an elegant form, is fashionable, and is easy to breed as an ornamental fish. It is popular around.

The betta fish, like other ornamental fishes, dung and urine in the aquarium, and the dung, urine, and residual food cause deterioration of the water quality, so it is necessary to change the water regularly. In addition, this betta fish has the property of threatening and attacking other individuals entering the territory, so it had to be raised alone.
In this way, when a single individual is bred in a water tank, the large water tank is generally poorly balanced (looks lonely). There is a problem of being fast. For example, since it is preferable to change the water in the aquarium at a frequency of about one week or two weeks, it is troublesome and difficult especially for young women who work.
Such a water change problem is not limited to the above-mentioned ornamental fish called solid, but is also one of the most popular problems when raising seafood in general in an aquarium.

  Therefore, in order to solve such a problem, a technique disclosed in Patent Document 1 has been proposed.

The water tank disclosed in Patent Document 1 has a structure in which water can be easily changed by using water pressure without lifting or tilting the water tank. To do. That is, an impurity storage bottom space in which impurities such as feces and residual food accumulate is formed on the bottom surface of the water tank body, and an inflow portion (discharge portion) is provided in the impurity storage bottom space, and this inflow portion (discharge portion) A tubular discharge passage having a predetermined length is connected to the water tank, and the discharge passage is arranged so as to rise up to a region above the outer surface of the water tank body along the depth direction (vertical direction) of the water tank body. Is open to the outside.
Then, by pouring a predetermined amount of new water from the upper surface of the water tank that is open to the water tank body, the water in the impurity storage bottom space and the discharge path of the water tank body (the old one containing feces and residual food) Water) is automatically swept away (overflowed) through the discharge port, and the water tank is always filled with a predetermined amount of clean water.

However, in the case of the aquarium disclosed in Patent Document 1, the amount of water that is about the same as the amount of newly poured water is surely discharged to the outside through the inflow part (discharge part) / discharge path. The mechanism is (overflowed), but the impurity storage bottom space defined in the bottom area of the aquarium body is a flat area, and the outlet at the end of the drainage path is located above the aquarium body. Since the distance in the vertical direction to the outlet is long, in such a form, the discharged water is not always old water that contains all feces and residual food.
Therefore, in the water tank disclosed in Patent Document 1, there is a very high probability that feces and residual food remain without being discharged.

A water tank disclosed in Patent Document 2 has also been proposed.
In the case of the aquarium disclosed in Patent Document 2, a bottom portion of the aquarium body is formed in an inclined shape, and an insole plate having a dropping hole for dropping feces etc. to the bottom portion is provided horizontally above the bottom portion, A drainage cock is provided at the deepest part of the bottom. That is, the region above the mid-sole plate is a breeding region for fish and the like, and the region below the mid-sole plate is an accumulation region for feces.
Therefore, feces or residual food excreted by organisms such as fish falls from the fall hole of the bottom plate to the bottom. Then, by opening the cock, feces, remaining food, etc. dropped on the bottom are efficiently discharged from the cock to the outside of the water tank along with the inclined surface of the bottom.

  However, in the case of the aquarium disclosed in Patent Document 2, the water in the aquarium is drained sequentially from the cock while the cock is open. To the safety, there is a possibility that not only the water in the accumulation area of the fish but also all the water in the fish breeding area will be drained and dried up. In the worst case, all the breeding fish may die. The lack of consideration.

If it is, the support case is not particularly necessary.
Furthermore, it is also possible to make a case body having a size and a support structure that can arrange a plurality of aquarium bodies 1 in parallel, and by configuring in this way, for example, in warming the aquarium body with a heater in winter, Only one large single case body needs to be warmed, and it is very useful to save time and labor for arranging a heater for each water tank.

  In the boundary area between the first cylinder part 3 and the second cylinder part 11, the internal space of the first cylinder part 3 and the internal space of the second cylinder part 11 are respectively a seafood accommodation area (upper area) A1 and A partition plate 31 is provided that is divided into a storage area (lower area) A2 where seafood droppings and residual food accumulate.

The partition plate 31 is formed in a rectangular shape in plan view having a through-hole 33 through which seafood droppings and residual food can pass, and seafood cannot pass through. The shape and the number of the through holes 33 are not particularly limited as long as they have a hole diameter that allows for the addition of seafood droppings and residual food and prevents the passage of seafood.
In addition, the overall shape of the partition plate 31 is not particularly limited, and may be arbitrary as long as it has an outer peripheral surface shape that matches the inner surface shape of the water tank body 1.
When the partition plate itself has elasticity, for example, although not illustrated, the partition plate itself includes a support piece that protrudes horizontally from a predetermined position on the side surface of the partition plate, and is provided on the inner surface of the boundary region between the first tube portion 3 and the second tube portion 11. Adopts a structure in which the holding hole for inserting and holding the support piece is recessed, the support piece is bent against its elasticity, and is held back by its elasticity when inserted into the holding hole It is also possible to do.

The discharge path 41 is formed in a substantially U shape with a circular pipe having a predetermined length, and has an end portion (downstream end portion) located on the opposite side of the end portion (upstream end portion) connected to the discharge portion 15. An open discharge port 49 is formed, and an open / close valve 51 is disposed in the discharge port 49. In the present embodiment, the discharge path 41 is a hard synthetic resin circular tube, but is not limited to this, and may be a soft synthetic resin circular tube.
And the discharge path 41 is continued from the discharge part 15 in the exterior of the water tank main body 1 along the depth direction (vertical direction H) of the water tank main body 1, and the discharge port 49 opened to the end thereof. Is arranged at a predetermined height above the position of the partition plate 31 in the depth direction of the water tank body 1.

The discharge path 41 of the present embodiment is integrally formed with a short cylindrical first vertical pipe line 43 to which one end side is detachably attached to the discharge part 15, and the first vertical pipe line 43, and horizontally. A short cylindrical horizontal pipe 45 is provided, and a long cylindrical second vertical pipe 47 formed integrally with the horizontal pipe 45 and raised along the outer surface of the water tank body 1.
Moreover, in this embodiment, the terminal side of the 2nd vertical pipe line 47 is extended in the horizontal direction at short length, and forms the discharge port 49. FIG.
The first vertical pipe 43 and the discharge portion 15 may be attached by screwing, or may be fastened by a fastening band after fitting, and the design within the scope of the present invention can be changed as appropriate.

The opening / closing valve 51 is accommodated in a cylindrical outer conduit 53 in which a discharge port 49 of the discharge passage 41 is detachably fitted and attached in a communication manner, and is accommodated in the outer conduit 53, and is laterally centered about a vertical axis. The inner pipe 55 is rotatably arranged in the direction indicated by the symbol R1 in FIGS. 2 and 3 and an operation portion 57 formed integrally with the upper end side of the inner pipe 55. The end (lower end) of the inner conduit 55 is opened (end opening 55b).
The operation portion 57 is integrated in the horizontal direction from the outer peripheral surface of the cylindrical portion 59 that is partially embedded in the inner pipe 55 and is integrally fitted and fixed, and the cylindrical portion 59 that protrudes from the upper end of the inner pipe 55. And an operation knob 61 that protrudes into the area.

In the present embodiment, an opening (inner pipe side opening) 55a that can communicate with the discharge port 49 of the discharge path 41 is provided in the inner pipe 55, and the inner pipe 55 is rotated in the left-right direction R1 by the operation unit 57. Thus, the discharge port 49 and the inner duct side opening 55a can be switched between communication and non-communication.
Although the on-off valve 51 is a manual type in this embodiment, it may be configured to be able to be automatically opened and closed by an electrical configuration.

The discharge port 49 is disposed at the lowest part of the first cylindrical portion 3, that is, at a position that is raised by a predetermined height in the vertical direction H from the upper surface position of the partition plate 31. The predetermined height position is a height at which an absolute water amount can be secured on the partition plate 31.
That is, the discharge port 49 is disposed at a height position where the discharge operation can be performed while ensuring an absolute amount of water that allows the seafood in the aquarium to swim.
Here, the absolute amount of water refers to the minimum amount of water that seafood can normally swim, that is, the minimum amount of water that is necessary for the seafood to naturally swim without slanting or lying down. In the present embodiment, the water surface position indicated by reference numeral L1 in FIG. 3 is the surface position of the absolute water amount.

When performing water change in the water tank of this embodiment, it operates as follows.
First, when feces, residual food or the like has accumulated in the storage area A2 (in the state shown in FIG. 2), the inner pipe 55 is rotated in a predetermined direction with the operation knob 61 of the opening / closing valve 51 to discharge the outlet of the discharge path 41. 49 and the opening (inner pipe side opening) 55a of the inner pipe line 55 are communicated. Then, due to the water pressure in the water tank, the water mixed with the storage area A2 and feces and residual food in the discharge passage 41 is pushed out from the discharge port 49 into the inner conduit 55 through the inner conduit side opening 55a. Then, the gas is discharged from the end opening 55b of the inner conduit 55 (FIG. 3).
In FIGS. 2 and 3, the symbol F indicates feces, remaining food, and the like.
And if the water in the water tank main body 1 falls to the same position (surface position L1 of absolute water amount) as the position of the discharge port 49, the discharge (overflow) of the water from the discharge port 49 stops (FIG. 3).
Accordingly, even if the open / close valve 51 is opened to drain unnecessary water mixed with feces, residual food, etc., the drainage always stops at the absolute water amount position L1, and seafood can safely swim in the aquarium. Since water always remains, there is no burden on seafood.
Next, the inner pipe 55 is rotated in a predetermined direction with the operation knob 61 of the opening / closing valve 51, and the positions of the discharge port 49 of the discharge path 41 and the inner pipe side opening 55a are shifted so as not to communicate (state in FIG. 2). . After that, a predetermined amount of water is replenished in the water tank body 1. At the time of this water replenishment, the inner pipe side opening 55a is displaced from the discharge port 49, and the discharge port 49 is closed by the outer peripheral surface of the inner pipe line 55, so that the replenished water fills up to the position of the discharge port 49. The seafood storage area (upper area) A1 is filled with a predetermined amount of water.

  The discharge path 41 may be configured such that its length can be expanded and contracted in the vertical direction H as shown in FIG.

  In the embodiment shown in FIG. 4, the second vertical pipe 47 of the discharge path 41 is divided into two at a predetermined position in the length direction (vertical direction H) of the pipe, and the upper pipe (upward) divided into two is divided. The outer diameter of the pipe) 47a is formed to be slightly smaller than the inner diameter of the lower pipe (lower pipe) 47b, and the upper pipe 47a passes through the lower pipe 47b in the length direction (vertical direction). H) is slidably fitted so as to be movable. Reference numeral S denotes a sealing material (O-ring) disposed to seal the fitting region. As long as the fitting region can be sealed, the sealing material is not limited to the O-ring, and other sealing structures can be adopted.

By adopting a configuration in which the second vertical pipe 47 can be adjusted in the vertical direction in this way, the amount of water left in the aquarium body 1 during drainage such as water change, that is, the absolute water amount L1 can be increased or decreased.
If the upper pipe 47a is extended upward, the absolute water amount can be increased, and if the upper pipe 47a is contracted downward, the absolute water quantity can be reduced. Therefore, when the seafood to be reared is large, the upper pipe 47a If the seafood is small, the upper pipe 47a may be shortened downward.
Although not shown, when the discharge path 41 is configured to be adjustable in length, a plurality of insertion ports 27 for supporting the discharge port 49 side may be provided.
The arrangement position of the partition plate 31 can also be changed up and down in the vertical direction H. In this embodiment, as shown in FIG. 2 and FIG. 3, a plurality of partition plate support pieces 70 project from the water tank body 1, and an arbitrary partition plate support piece 70 is selected and the partition plate 31 is disposed. Like that.

In the present embodiment, the water tank main body 1 has been described with an embodiment in which the first tube portion 3 and the second tube portion 11 are integrally formed. The cylindrical part 3 and the second cylindrical part 11 may be separately molded, assembled and integrated, and either the first cylindrical part 3 or the second cylindrical part 11 is made of a hard resin material. And either one may be made of a soft resin material.
In addition, a delivery fan capable of forcibly delivering residual food, feces, and the like in the direction of the discharge path 41 is installed in the second cylinder portion 11, specifically, in the discharge portion 15 and in the vicinity of the discharge portion 15. Is also possible. In this case, the installation method of the delivery fan can be arbitrarily changed within the scope of the present invention.
Further, instead of the opening / closing valve 51 of the present embodiment, an opening / closing lid structure that can open and close the discharge port 49 of the discharge passage 41 and can be sealed can be adopted, and when a predetermined opening prevention mechanism is released. It is sufficient that the discharge port 49 can be opened only within the scope of the present invention.
