Description

Technical Field

[0001] The utility model relates to the technical field of ecological environment protection of water conservancy and hydropower engineering, in particular to a fish collecting box and a fish collecting system. Background Art

[0002] As a renewable clean energy, water conservancy and hydropower projects have huge economic and social benefits such as flood control, power generation, shipping, and emission reduction, but at the same time they have a great negative impact on the river's ecological environment. Engineering hubs inevitably destroy the connectivity of rivers, block fish migration channels, block fish gene exchange, and cause damage to ecological diversity. Therefore, it is very necessary to design and build fishways, simulated natural channels, fish lifts, fish locks, fish collection and transportation systems, or fish passing facilities in different combinations for the purpose of protecting fish resources.

[0003] In fish collection and transportation systems such as fish elevators and fish locks, fish collection boxes are one of the most important components, which need to be placed in fish collection tanks. The current fish collection box structure is mostly a rectangular container with a fixed wall, which has poor adaptability to water depth. The wall of the box has a certain blocking effect on the movement of fish. When the box is transported, it will greatly disturb the water in the fish collection tank, which is easy to cause fish to escape and affect the fish collection effect. Utility Model Content

[0004] The utility model aims to provide a fish collecting box and a fish collecting system to solve the problems that the existing fish collecting box has poor adaptability to water depth, the box wall hinders the movement of fish, and the box greatly disturbs the water body of the fish collecting tank when it is transported, thus affecting the fish collecting effect.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0023] like Figure 1 As shown, a fish collecting box provided in this embodiment includes an end plate 1, a folding plate 6, a rotating shaft 3 and a gauze net 5.

[0024] The end plate 1 is a long rectangular plate, and two of them are provided. One end of the two end plates 1 is connected by a rotating shaft 3, and the other end of the two end plates 1 is connected to a gauze 5. The length of the end plate 1 matches the width of the fish collecting tank, which is generally 1.9m. The height of the end plate 1 matches the water depth. The length of the gauze 5 is equal to the length of the end plate 1. The mesh diameter of the gauze 5 is smaller than the cross-sectional area of ​​the induced fish body. The height of the gauze 5 is not less than the inner water depth of the fish collecting tank.

[0025] The length of the end plate 1 matches the water depth, and the width matches the width of the fish collecting tank. The opening and closing angle of the end plate 1 is 90° to 180°.

[0026] The rotating shaft 3 includes a sleeve 31 and a rotating sleeve rod 32 rotatably arranged in the sleeve 31. One end plate 1 is connected to the sleeve 31, and the other end plate 1 is connected to the rotating sleeve rod 32. In a specific embodiment, there are two sleeves 31, which are arranged at intervals at both ends of the length direction of the end plate 1, and the rotating sleeve rod 32 is inserted between the two sleeves 31 at the same time. The structure of the sleeve 31 and the rotating sleeve rod 032 is similar to that of a hinge shaft.

[0027] There are two folding plates 6, which include side plates 2 and folding membranes 4. The side plates 2 are fan-shaped plates with a radius of 1.8m and a central angle of 45°. Two side plates 2 are provided. The ends of the two side plates 2 that are away from each other are connected to the end plates 1 at the corresponding positions, and the ends of the two side plates 2 that are close to each other are connected to the folding membranes 4. The folding membranes 4 are thin films that can be deformed and closed autonomously under force.

[0028] When the end plate 1 is closed and the folding plate 6 is folded, the gauze 5 is in a vertical state; when the end plate 1 is opened and the folding plate 6 is unfolded, the gauze 5 is in a flat state.

[0029] The utility model also provides a fish collecting system, comprising a fish collecting tank and the above-mentioned fish collecting box placed in the fish collecting tank.

[0030] like Figure 2As shown, the end plate 1 can be opened along the rotating shaft 3 to a horizontal state, and the folding plate 6 is fully unfolded. At this time, the end plate 1 is in contact with the bottom of the fish collecting tank, the folding plate 6 is in contact with the side wall of the fish collecting tank, the top of the fish collecting box is completely open, and the gauze 5 falls naturally, thereby avoiding the influence of the box wall on the movement of fish to the greatest extent.

[0031] like Figure 3 As shown, when fish gather above the fish collecting box, the gauze 5 is lifted up, and the end plate 1 can be closed along the rotating shaft 3. At this time, the two side plates 2 push the folding film 4 to compress, the end plate 1 is inclined, the gauze 5 is vertical, and the cross-section of the fish collecting box is a triangle.

[0032] When the fish collecting box is transported, the gauze 5 on the top of the end plate 1 is first lifted above the water surface to block the escape channel of the fish in the fish collecting box body area. Then the two end plates 1 are lifted until the two end plates 1 and the four side plates 2 are folded together to form a closed fish collecting container. The fish are gathered in the fish collecting box, and then the fish collecting box is transported to a designated location.

[0033] The fish collecting box provided by the utility model has an end plate 1 that is unfolded to a flat plate shape when collecting fish, so as to induce the fish to enter the water area above the fish collecting box without any hindrance. When catching fish, the gauze 5 is first lifted above the water surface to block the escape channel of the fish, and then the two end plates 1 are lifted until the two end plates 1 and the four side plates 2 are folded together to form a closed fish collecting container. The fish collecting box is convenient to open and close, flexible in collection and transportation, has strong adaptability to water depth, has little interference with fish, and can effectively improve the efficiency of fish collecting.

[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
