Technical Field

[0001] This utility model relates to a fish passage for rewilding training, and more particularly to a spiral fish passage for rewilding training. Background Technology

[0002] A rewilding training fishway is a facility that combines ecological engineering and biological behavior to help artificially bred fish (especially migratory fish) regain their wild instincts and adapt to the living conditions of natural waters by simulating natural river environments.

[0003] In order to have a certain height difference so as to better simulate the natural river environment, the shape of the fishway for wild training is generally linear, which tends to result in a large area. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a spiral rewilding training fishway, which not only has a height difference to better simulate the natural river environment, but also occupies a small area.

[0005] Technical solution:

[0006] A spiral rewilding training fishway includes:

[0007] Barrel-shaped pool;

[0008] A fishway is spirally fitted outside the barrel-shaped pool. The lower end of the fishway has a first opening and a discharge outlet, and the upper end of the fishway has a second opening. The first opening is connected to the top of the barrel-shaped pool through a return water pump, and the second opening is connected to the top of the barrel-shaped pool through an outlet water pump.

[0009] The gate is locked inside the discharge port.

[0010] Optionally, the fishway includes a first channel body, several fishway bodies, and a second channel body connected in sequence. The several fishway bodies are all spirally sleeved on the outside of the barrel-shaped pool. The first opening and the discharge port are both located in the first channel body, and the second opening is located in the second channel body.

[0011] Optionally, the fishway body is provided with several baffles arranged at intervals.

[0012] Optionally, the connection between the first opening and the return water pump has a first permeable mesh, and the connection between the second opening and the outlet water pump has a second permeable mesh.

[0013] Optionally, the barrel-shaped pool includes a pool body and a pool cover that are detachably connected to each other, the fish passage is spirally sleeved on the outside of the pool body, the first opening and the pool cover are connected through a return water pump, and the second opening and the pool cover are connected through an outlet water pump.

[0014] Optional, also includes:

[0015] A drain outlet is located at the bottom of the pool body;

[0029] Example 1

[0030] like Figures 1-2 This embodiment provides a spiral rewilding training fishway, including: a barrel-shaped pool 1; a fishway 2 spirally connected to the outside of the barrel-shaped pool 1, the lower end of the fishway 2 having a first opening 211 and an outlet 212, the upper end of the fishway 2 having a second opening 231, the first opening 211 and the top of the barrel-shaped pool 1 being connected by a return water pump 31, the second opening 231 and the top of the barrel-shaped pool 1 being connected by an outlet water pump 32; and a gate 4 movably locked inside the outlet 212.

[0031] Specifically, during operation, firstly, the water pump 32 is started, and the water pump 32 allows water from the barrel-shaped pool 1 to enter the high end of the fishway 2 through the second opening 231. Under the action of gravity, the water flows from the high end of the fishway 2 to the low end of the fishway 2, and then flows back into the barrel-shaped pool 1 through the return pump 31 and the first opening 211. Next, the fish are placed in the fishway 2. Due to the migratory instinct of the fish, they swim against the direction of the water flow in the fishway 2, which facilitates the rewilding training of the fish. Finally, after the fish have completed the rewilding training, the gate 4 is opened, and the fish and water are released into the external natural environment under the action of gravity.

[0032] The barrel-shaped pool 1 serves as a water storage device. Since the spiral fishway 2 naturally forms a barrel-shaped space, this design sets up a water storage device (i.e., barrel-shaped pool 1) within the barrel-shaped space, eliminating the need for an additional water storage device. This minimizes the footprint of the spiral rewilding training fishway 2 and allows for better simulation of a natural river environment due to the height difference of the spiral fishway 2. The outlet pump 32 facilitates water entering the upper part of the fishway 2 through the second opening 231. The outlet pump 32 can be centrifugal, volumetric, or other types. The return pump 31 facilitates water returning to the barrel-shaped pool 1 through the first opening 211. The return pump 31 can be centrifugal, volumetric, or other types.

[0033] Furthermore, such as Figures 1-2 The fishway 2 includes a first channel body 21, several fishway bodies 22 and a second channel body 23 connected in sequence. The several fishway bodies 22 are all spirally connected to the outside of the barrel-shaped pool 1. The first opening 211 and the discharge port 212 are both located in the first channel body 21, and the second opening 231 is located in the second channel body 23.

[0034] Specifically, the first channel body 21, several fish passage bodies 22, and the second channel body 23 are all used for the flow of fish and water. The first channel body 21, several fish passage bodies 22, and the second channel body 23 can be prefabricated in the factory in advance, thereby increasing the ease of installation of the spiral wilding training fish passage 2 in this scheme.

[0035] Furthermore, such as Figure 2 The fishway body 22 is equipped with several baffles 24 arranged at intervals.

[0036] Specifically, the baffle 24 not only reduces the water flow rate but also allows fish to rest properly.

[0037] Furthermore, such as Figures 1-2 The first opening 211 and the connection between the return water pump 31 have a first permeable mesh, and the second opening 231 and the connection between the outlet water pump 32 have a second permeable mesh.

[0038] Specifically, the first permeable net is used to prevent fish from entering the return water pump 31, thus protecting the fish; the second permeable net is used to prevent fish from entering the outlet water pump 32, thus protecting the fish.

[0039] Furthermore, such as Figures 1-2 The barrel-shaped pool 1 includes a pool body 11 and a pool cover 12 that are detachably connected to each other. The fish passage 2 is spirally sleeved on the outside of the pool body 11. The first opening 211 and the pool cover 12 are connected through a return water pump 31, and the second opening 231 and the pool cover 12 are connected through an outlet water pump 32.

[0040] Specifically, the detachable connection between the pool body 11 and the pool cover 12 facilitates timely observation or maintenance of the interior of the barrel-shaped pool 1.

[0041] Furthermore, such as Figures 1-2 It also includes: a drain outlet 13 located at the bottom of the pool body 11; a first solenoid valve 51 connected to the drain outlet 13; a water level gauge located inside the pool body 11; and a controller electrically connected to both the first solenoid valve 51 and the water level gauge.

[0042] Specifically, when the water level gauge detects that the water level in the pool 11 is too high, the water level gauge transmits the detection signal to the controller, and the controller opens the first solenoid valve 51, so that the water in the pool 11 is discharged through the drain outlet 13 under the action of gravity. When the water level gauge detects that the water level in the pool 11 is normal, the water level gauge transmits the detection signal to the controller, and the controller closes the first solenoid valve 51.

[0043] The first solenoid valve 51 can be a direct-acting type, a pilot-operated type, etc.; the water level gauge can be a radar type, an ultrasonic type, etc.

[0044] Furthermore, such as Figures 1-2 It also includes: a water inlet 14 located on the pool cover 12; a second solenoid valve 52 connected to the water inlet 14, the second solenoid valve 52 being electrically connected to the controller.

[0045] Specifically, when the water level gauge detects that the water level in the pool 11 is too low, the water level gauge transmits the detection signal to the controller, and the controller opens the second solenoid valve 52 to allow rainwater from the outside to enter the pool 11 through the inlet 14. When the water level gauge detects that the water level in the pool 11 is normal, the water level gauge transmits the detection signal to the controller, and the controller closes the second solenoid valve 52.

[0046] The second solenoid valve 52 can be of the form of direct-acting or pilot-operated.

[0047] Furthermore, such as Figures 1-2 Along the edge of the pool cover 12 towards the center, the vertical height of the pool cover 12 gradually decreases.

[0048] Specifically, the pool cover 12 is concave, which makes it easier for the pool cover 12 to collect rainwater, and thus makes it easier to replenish water to the pool body 11 through the water inlet 14.

[0049] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
