Technical Field
[0001] The invention relates to the technical field of river ecological regulation, and in particular to a river fish habitat device. Background Art
[0002] Rural and urban rivers are important environments for nurturing human civilization, important carriers of rural and urban ecological environments, play an important role in social and economic development, and are an indispensable factor in the human living environment. In recent years, with the flood control and pollution prevention renovation of rural and urban rivers, cement mortar masonry construction technology has been used for river channels and riverbanks. Although the extensive use of cement mortar masonry meets the requirements of flood control and pollution control, the firmness and smoothness of cement mortar masonry have made various aquatic organisms and microorganisms lose their habitats. When river floods occur, aquatic organisms such as fish and crabs are easily washed away by large water flows and cannot survive, causing serious ecological disasters, and the balance of river ecosystems and biodiversity are seriously threatened. Therefore, a shelter environment for fish to live in should be set up during the river regulation process. Summary of the invention
[0003] In view of the above problems, the present invention provides a fish cave for fishes to live in and a fish cave environment system having the same.

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0027] Embodiment 1
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fish cave comprises a horizontally placed cylinder 1, which is a cylinder. The cylinder 1 is provided with a front cover 11 and a rear cover 12 for closing the cylinder openings at the front and rear ends, and the front cover 11 and the rear cover 12 are circular in shape. An inlet 110 is provided at the upper part of the front cover 11, and a water storage chamber is formed at the lower part of the cylinder 1. At least one first partition 13 and at least one second partition 14 are provided in the cylinder 1, and a first notch 131 is provided on the first partition 13, and a second notch 141 is provided on the second partition 14, and the first notch 131 does not overlap with the second notch 141.
[0029] The upper part of the front end of the cylinder 1 is provided with a convex eave 15 extending forward from the cylinder wall of the cylinder 1, and the convex eave 15 is used to prevent garbage sludge from being washed into the inlet by water. The upper end of the convex eave 15 is higher than the upper end of the inlet 110, and the lower end of the convex eave 15 is lower than the lower end of the inlet 110.
[0030] The first partition plate 13 and the second partition plate 14 are parallel to the front end cover 11, the first notch 131 is located at one end of the first partition plate 13 in the horizontal direction, and the second notch 141 is located at one end of the second partition plate 14 away from the first notch 131. Figure 4 The first notch 131 is located at the left end of the first partition 13, and the second notch 141 is located at the right end of the second partition 14. The first notch 131 and the second notch 141 are in a minor arc shape, while the first partition 13 after the first notch 131 is provided and the second partition 14 after the second notch 141 is provided are in a major arc shape.
[0031] The cylinder 1 is formed by connecting two upper arc plates 1a and lower arc plates 1b with semicircular cross sections. A slide groove 16 is provided on the end surface of the lower arc plate 1b close to the upper arc plate 1a, and a slider 17 matching the slide groove 16 is provided on the end surface of the upper arc plate 1a close to the lower arc plate 1b. The lower arc plate 1b is an integrated structure with the front end cover 11, the first partition plate 13, the second partition plate 14 and the rear end cover 12, and the upper arc plate 1a is an integrated structure with the convex eaves 15.
[0032] The fish cave is cast in concrete as a whole. This split setting facilitates demoulding during production and makes assembly and construction more labor-saving and time-saving.
[0033] The fish cave of the present invention can be set at the bottom of both sides of the river channel for aquatic organisms in the river channel to live. Fish and other aquatic organisms can enter the inner cavity of the cylinder 1 through the inlet 110. When the river channel is flooded, the cylinder 1 can provide shelter for the fish to avoid being washed away by the flood. When the water level of the river channel is lowered, the lower part of the cylinder 1 can temporarily store water for the fish to take shelter. By setting the first notch 131 and the second notch 141 on the first partition 13 and the second partition 14, which do not overlap, malicious capturers can be prevented from directly reaching into the cylinder with their hands or tools, so that aquatic organisms can survive safely in the fish cave.
[0034] Embodiment 2
[0035] like Figure 5 and Figure 6 As shown, the difference from the first embodiment is that the distance that one end of the convex eave 15 protrudes forward in the horizontal direction is greater than the distance that the other end protrudes forward, and the transition is made through an arc surface. Figure 6 The forward protrusion distance of the left end of the middle convex eave 15 is greater than the forward protrusion distance of the right end. When water flows, the end of the convex eave 15 that protrudes forward for a longer distance is used to block garbage and silt, and the streamlined design reduces the impact of the convex eave on the water flow.
[0036] Embodiment 3
[0037] like Figure 7 and Figure 8 As shown, the present invention also provides a fish cave environment system, comprising a plurality of the aforementioned fish caves arranged in parallel and connecting pipes. The fish caves are arranged in parallel in sequence along the direction of the river flow, and a through hole 121 is provided at the lower part of the rear end cover 12, and the through holes 121 of each fish cave are connected through a connecting pipe.
[0038] The connecting pipeline includes a plurality of connecting pipes 2 and a plurality of three-way pipes 3. One end opening of the three-way pipe 3 is connected to the through hole 121 of the fish cave. The three-way pipes 3 on two adjacent fish caves are connected via the connecting pipe 2.
[0039] The connecting pipeline can also be a longer connecting pipe 2 and a plurality of conduits. A plurality of connecting holes 21 are provided on the wall of the connecting pipe 2 along the length direction, and the through hole 121 is connected to the connecting holes 21 through the conduits.
[0040] A manhole 4 is arranged every several fish caves, and the manhole 4 is communicated with two adjacent fish caves through a connecting pipe. The plane of the bottom of the manhole 4 is lower than the plane of the riverbed, and the setting of the manhole can store large fish and fish transfer places.
[0041] In this way, multiple fish caves are connected together to form an environmental system, which is convenient for aquatic organisms to escape from natural enemies in the fish caves. It is also suitable for cave-dwelling organisms such as crayfish and eels. The environmental system is installed behind a river with a dam, which can also help migratory fish swim back upstream to lay eggs. The outlet of the connecting pipe connected to a fish cave at the end of the fish cave environmental system is connected to the water surface of the dam or is lower than the dam, so that fish, shrimp and crabs can enter and exit freely.
[0042] The fish cave and the fish cave environment system having the same of the present invention can not only be used in newly built river channel reconstruction projects, but can also be directly used in existing cement mortar stone masonry river channels to improve the water ecological environment system.
