[0002] Biodiversity is the material basis for human survival and development, including terrestrial biodiversity, aquatic biodiversity and microbial diversity. Fish diversity is part of aquatic biodiversity. Fish diversity refers to the species composition, diversity index changes, dominant species, quantity and weight abundance changes of fish. Traditional fish diversity observations mostly use manual survey methods, which are time-consuming and labor-intensive, with poor timeliness and may cause harm to the fish. Underwater video is an important technology for non-destructive monitoring of fish diversity. Generally, underwater cameras are used to shoot fish activities for manual and computer automatic identification of fish species. However, in inland rivers and lakes, due to the low transparency of water quality and fluctuations with rainfall and changes in water quality entering rivers and lakes, the effect of underwater video is poor, which affects visual senses and also brings certain errors to fish species identification.

DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] See also Figure 1 Now, a fish monitoring device provided by the utility model is described. The fish monitoring device comprises: a water tank 1, a water pump 2, a filter 3 and a one-way valve 4. The water tank 1 is equipped with a camera 5, and a water inlet and a water outlet are provided on the water tank 1; the water pump 2 is connected to the water inlet; the filter 3 is located between the water tank 1 and the water pump 2; the one-way valve 4 is installed at the water outlet, the outlet of the one-way valve 4 is far away from the water outlet, and a transmission channel 401 for fish to pass through is provided in the center of the one-way valve 4.

[0027] Compared with the prior art, the fish monitoring device provided in this embodiment has a water pump 2 that continuously extracts water from the water body, and transmits water to the water tank 1 after filtering through the filter 3, thereby ensuring the transparency of the water in the water tank 1. The one-way valve 4 can prevent the water outside the water tank 1 from entering the water tank 1 through the water outlet, while the fish can freely enter and exit the water tank 1 through the transmission channel 401 in the one-way valve 4. The camera 5 in the water tank 1 can take pictures and videos of the fish entering the water tank 1, thereby obtaining information on the diversity of fish.

[0028] In this embodiment, the output power of the water pump 2 is adjusted to change the water flow velocity in the transmission channel 401, so that the water flow velocity in the transmission channel 401 is within a reasonable range to avoid affecting the normal activities of fish.

[0029] In some embodiments, see Figures 1 to 5 , a vortex channel is provided in the one-way valve 4, and the vortex channel includes a first drainage channel 402, a second drainage channel 403 and a third drainage channel 404 which are connected in sequence, the first drainage channel 402 is located on the side close to the outlet of the one-way valve 4, and the first drainage channel 402 and the third drainage channel 404 are both inclined to the side of the water flow direction in the transmission channel 401. In this embodiment, the one-way valve 4 is cylindrical, and the transmission channel 401 is located at the axis of the one-way valve 4. The vortex channel is opened on the inner wall of the transmission channel 401, and the vortex channel is used to prevent the water flow in the transmission channel 401 from flowing in the reverse direction. When the external water enters the transmission channel 401 in the reverse direction, a part of the water in the transmission channel 401 will pass through the first drainage channel 402, the second drainage channel 403 and the third drainage channel 404 in sequence, and then re-enter the transmission channel 401. Since the first drainage channel 402 and the third drainage channel 404 are both inclined toward one side of the water flow direction in the transmission channel 401, the water that enters the transmission channel 401 in the reverse direction will more easily enter the first drainage channel 402, and the direction of the water flow that re-enters the transmission channel 401 from the third drainage channel 404 is changed, thereby creating resistance to the reverse water flow in the transmission channel 401, so that the water flow in the transmission channel 401 flows forward, and finally achieving unidirectional flow of water.

[0030] In some embodiments, see Figure 4 , there are multiple vortex channels, which are evenly arranged along the water flow direction in the one-way valve 4. In this embodiment, the more vortex channels there are, the more branches connected to the transmission channel 401 there will be, the greater the resistance of the water flow passing through the branch to the reverse water flow, and the energy of the reverse water flow will become smaller and smaller, thereby ensuring that water with poor transparency from the outside will not enter the water tank 1.

[0031] In some embodiments, see Figure 4 and Figure 5, the first drainage channel 402 and the third drainage channel 404 are both annular structures. In this embodiment, the first drainage channel 402 and the third drainage channel 404 are both annular grooves, and the annular grooves are coaxial with the transmission channel 401. The first drainage channel 402 and the third drainage channel 404 adopt an annular structure, thereby increasing the proportion of reverse water flow entering the vortex channel.

[0032] In some embodiments, see Figure 4 and Figure 5 , the number of the second drainage channels 403 is multiple, and they are evenly arranged along the circumference of the one-way valve 4. In this embodiment, the second drainage channels 403 are circular holes. The multiple second drainage channels 403 are evenly arranged along the circumference of the one-way valve 4, so that the water flow can quickly pass between the first drainage channel 402 and the third drainage channel 404.

[0033] In some embodiments, see Figure 4 , the opening size of the third drainage channel 404 is larger than the opening size of the first drainage channel 402. In this embodiment, since the opening size of the third drainage channel 404 is larger than the opening size of the first drainage channel 402, the water pressure at the opening of the third drainage channel 404 is lower than the water pressure at the opening of the first drainage channel 402, so the flow rate of the water flow can be accelerated.

[0034] In some embodiments, see Figure 1 , the number of the one-way valves 4 is multiple. In this embodiment, multiple one-way valves 4 are installed at different positions on the periphery of the water tank 1, so more channels are provided for the fish to enter and exit the water tank 1, reducing the impact on the normal activities of the fish.

[0035] In some embodiments, see Figure 1The filter 3 includes a shell 301, an upper filter screen 302, a lower filter screen 303, a first water inlet pipe 304, a second water inlet pipe 305 and a water outlet pipe 306; the upper filter screen 302 and the lower filter screen 303 divide the inner cavity of the shell 301 into a first cavity 307, a second cavity 308 and a third cavity 309 from top to bottom, one end of the first water inlet pipe 304 and the second water inlet pipe 305 are respectively connected to the first cavity 307 and the third cavity 309, the other ends of the first water inlet pipe 304 and the second water inlet pipe 305 are both connected to the water outlet end of the water pump 2, and the water outlet pipe 306 is respectively connected to the second cavity 308 and the water tank 1. In this embodiment, the water pumped by the water pump 2 enters the first cavity 307 and the third cavity 309 through the first water inlet pipe 304 and the second water inlet pipe 305 respectively, enters the second cavity 308 under the filtering action of the upper filter 302 and the lower filter 303, and then enters the water tank 1 through the outlet pipe 306. In order to conveniently control the opening and closing of the first water inlet pipe 304 and the second water inlet pipe, valves can be installed on the first water inlet pipe 304 and the second water inlet pipe 305. In the actual working process, the operator can select the first water inlet pipe 304 and the second water inlet pipe 305 to be opened at the same time or one by one by controlling the valve. When the first water inlet pipe 304 is opened alone, the water entering the housing 301 will backwash the lower filter 303 downward, thereby cleaning the dirt on the lower filter 303; when the second water inlet pipe 305 is opened alone, the water entering the housing 301 will backwash the upper filter 302 upward, thereby cleaning the dirt on the upper filter 302.

[0036] In some embodiments, see Figure 1 The housing 301 is also provided with a first sewage pipe 310 and a second sewage pipe 311, wherein the first sewage pipe 310 is in communication with the first cavity 307, and the second sewage pipe 311 is in communication with the third cavity 309. In this embodiment, by installing the first sewage pipe 310 and the second sewage pipe 311 on the housing 301, it is convenient to discharge the dirt accumulated in the first cavity 307 and the third cavity 309. In order to conveniently control the opening and closing of the first sewage pipe 310 and the second sewage pipe 311, valves can be installed on the first sewage pipe 310 and the second sewage pipe 311.

[0037] In some embodiments, see Figure 1 , and further includes a buoy 6 and a solar panel 7; the solar panel 7 is fixed on the buoy 6, and the buoy 6 is connected to the water tank 1 by a rope. In this embodiment, the buoy 6 floats on the water surface by buoyancy, and the buoy 6 is connected to the water tank 1 by a rope, so that the water tank 1 floats in the water. The solar panel 7 is fixedly installed on the buoy 6, and the solar panel 7 can convert solar energy into electrical energy, thereby providing electrical energy for the electrical components in the device.
