DETAILED DESCRIPTION

[0040] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0041] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0043] In the description of the present application, “plurality” means two or more than two, unless otherwise precisely and specifically specified.

[0044] The terms "first", "second", "third", "fourth", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0045] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0046] Hydropower stations are places that use water resources to generate electricity. They are a way to develop clean energy. Hydropower stations can be divided into dam-type hydropower stations, water diversion-type hydropower stations, and hybrid hydropower stations. Dam-type hydropower stations require the construction of dams on rivers to convert the potential energy of water into mechanical energy and then into electrical energy. Existing hydropower stations have already formed a certain number of scales.

[0047] In recent years, a new idea of ​​"main stream development and tributary protection" has gradually emerged in the issue of river fish habitat protection. That is, tributary river sections are used as alternative habitats to mitigate the adverse effects of large-scale hydropower development on main stream habitats.

[0048] In order to mitigate the adverse effects of hydropower development on the connectivity of fish migration channels, measures such as dam removal, fishway construction, and net catching and releasing fish across dams have been promoted and applied. Among them, the net catching and releasing method mainly involves artificially trapping fish in the river section below the dam, and then transporting them live to the dam for release. The key to implementing this method is to efficiently trap fish and avoid body damage.

[0049] At present, the traditional methods of luring fish across the dam are mostly ground cages, gill nets, snares, etc., which will capture and concentrate fish with different habits at the same time, but have the disadvantages of low fish luring effect and great damage to the fish body.

[0050] In addition, in order to promote the protection of river fish resources, a large number of live samples are needed to carry out research on river fish breeding and aquaculture.

[0051] Based on the above technical problems, an embodiment of the present application provides a fish catching device, comprising: a fishing fence, at least one spoiler baffle and a fish attracting channel; the fish attracting channel is connected to the fishing fence, the fish attracting channel and the fishing fence are arranged to form a fish gathering area, the fish gathering area is used to collect fish through a fish inlet, the spoiler baffle is arranged in the fish gathering area, and the spoiler baffle is configured to rotate relative to the fishing fence and the fish attracting channel to shift the water flow in the fish gathering area, thereby creating a living environment to which different types of fish can adapt.

[0052] It is understandable that changes in the water flow environment in the fish gathering area can simulate the living environment of different types of fish and reduce damage to the fish bodies.

[0053] It should be noted that Figure 1 and Figure 2 The schematic diagram of each component of the fish catching device is shown. The specific structure of the remaining components of the fish catching device is not limited to Figure 1 and Figure 2 of examples.

[0054] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0055] Reference Figure 1 and Figure 2 As shown, a fish catching device provided in an embodiment of the present application is used to be arranged in waters such as rivers, lakes, and seas, and the fish catching device comprises: a fishing fence 100, at least one spoiler baffle 200, and a fish guiding channel. The fishing fence 100 is connected to the riverbed through a pre-buried anchor rod 900, and the top of the fishing fence 100 is located above the water surface to prevent the fish in the fishing fence 100 from escaping from the fishing fence 100.

[0056] The fish attracting channel includes two fences 300 arranged at intervals, and the interval between the two fences 300 gradually decreases so that the two fences 300 are arranged in a narrowed shape toward the inside of the fishing fence 100.

[0057] Part of the fence 300 extends to the outside of the fishing pen 100 .

[0058] The fishing fence 100 has an open mouth, and two fences 300 are arranged on the riverbed of the river at intervals, and the two fences 300 are respectively connected to the fishing fence 100 at both ends of the open mouth. It can be understood that the two fences 300 are respectively connected to the fishing fence 100 at the open mouth of the fishing fence 100, and a swimming channel for fish can be formed between the two fences 300 to guide the fish into the fishing fence 100.

[0059] It should also be noted that both the fishing fence 100 and the fence 300 allow water to flow freely through, so as to prevent the water from knocking down the fishing fence 100 and the fence 300.

[0060] The fence 300 extends toward the inside of the fishing fence 100 to form a fish inlet 400. The fence 300 and the fishing fence 100 are arranged to form a fish gathering area 500, and the fish gathering area 500 is used to collect fishes.

[0061] The spoiler baffle 200 is disposed in the fish gathering area 500 and is rotatably connected to at least one of the fishing fence 100 and the fence 300. The spoiler baffle 200 is configured to block a portion of the water flow in the fish gathering area 500 by rotating to change the water flow environment in the fish gathering area 500.

[0062] In the above embodiment, when the fish capturing device is used for fishing, the fishing fence 100 is first fixed to the riverbed by the anchor rod 900, and the top of the fishing fence 100 is exposed above the water surface, and then the fence 300 is respectively connected to the two ends of the open mouth of the fishing fence 100, and the spoiler baffle 200 is rotated to make the water flow wash the spoiler baffle 200, so that the water flow environment in the fish gathering area 500 changes. For example, the spoiler baffle 200 is rotated to be perpendicular to the water flow direction, so that the side of the spoiler baffle 200 facing the water flow direction can form a vortex area different from the conventional water flow, or the spoiler baffle 200 is rotated to be the same as the water flow direction, then the habitat in the fish gathering area 500 is the habitat of the conventional water flow. Different types of fish have different adaptability to the habitat. The above setting method can simulate the habitat of a variety of fish, improve the applicability of the fish capturing device, and reduce damage to the fish.

[0063] Here, the extension direction of the swimming channel for fish enclosed by the two fences 300 can be set along the flow direction of the water in the river, or it can be set perpendicular to the flow direction of the water in the river. That is, in order to adapt to the living environment of different fish, the direction in which the fish capturing device is set in the river can be changed. The present application does not impose any restrictions on the setting direction of the fish capturing device in the river.

[0064] In a specific implementation, the fishing fence 100 includes a support frame 110 and a plurality of railings 120 arranged on the support frame 110. The bottom of the support frame 110 is connected to the riverbed through an anchor rod 900. The railings 120 are arranged at intervals along the extension direction of the support frame 110. The support frame 110 is arranged in an arc shape. The diameter of the support frame 110 is set to 1.5m, the height of the railing 120 is 1.0m, the gap between two adjacent railings 120 is set to 0.03m, and the top of the railing 120 is 0.1m higher than the horizontal plane of the river.

[0065] The fence 300 includes a rope 310 and at least two fence pieces 320. The rope 310 is connected in series with the top of each fence piece 320 so that the fence pieces 320 are arranged at intervals along the telescopic extension direction. Each fence piece 320 is set to be 1m high and 0.3m wide. The gap between two adjacent fence pieces 320 can be adjusted by the rope 310, and the gap between two adjacent fence pieces 320 can be adjusted in the range of 0-0.1m.

[0066] In a possible implementation, in order to attract fish and improve the efficiency of fish capture, the fish capture device further includes a fish attracting mechanism 600 .

[0067] The fish attracting mechanism 600 includes at least one of a water flow fish attracting component 610 and a bait fish attracting component 620 .

[0068] The fishing fence 100 has a mounting portion 130 , which may be a plate or a bracket with a supporting function. The specific structure of the mounting portion 130 is not limited here.

[0069] The water flow fish attracting assembly 610 is connected to the mounting portion 130, and the water flow fish attracting assembly 610 is configured to discharge water toward the water flow direction of the river to attract fish into the fish gathering area 500. Alternatively, it can be understood that the water flow fish attracting assembly 610 utilizes the change of water flow and the principle of dynamics to attract fish.

[0070] The bait fish attracting assembly 620 is disposed on the mounting portion 130 , and the bait fish attracting mechanism 600 is configured to be diluted and flushed by the river to release bait into the river to attract fish to enter the fish gathering area 500 .

[0071] Here, the bait fish attracting mechanism 600 includes a bait box 621 and a dripping tube 622 arranged on the bait box 621. The bait box 621 is arranged on the mounting portion 130. The bait box 621 is used to hold a bait solution. The bait solution in the bait box 621 can be adaptively prepared according to the type of fish to be caught. The present application does not limit the type of bait. The dripping tube 622 is connected to the bait box 621. The dripping tube 622 has a dripping hole to drip the bait solution into the river through the dripping hole. Here, there is no limit on the concentration of the bait solution and the dripping speed of the dripping tube 622, and they can be adaptively adjusted as needed.

[0072] In the above embodiment, multiple fish luring methods coexist, which can improve the fish catching device's ability to lure various types of fish and improve the practicability of the fish catching device.

[0073] In order to further improve the practicality of the fish catching device, the fish attracting mechanism 600 further includes a sound and light fish attracting assembly 630, which is disposed on at least one of the fence 300 and the mounting portion 130. It is understood that the sound and light fish attracting assembly 630 can be disposed on the fence 300, or on the mounting portion 130, or both the fence 300 and the mounting portion 130 are provided with the sound and light fish attracting assembly 630, so as to improve the efficiency of trapping.

[0074] Specifically, the sound and light fish attracting component 630 includes a speaker and an LED light. The speaker can play a 400Hz sine wave, a continuous sine wave sound, or some biological sounds (such as courtship, feeding, and clustering) to attract fish. The LED light uses the fact that some fish are sensitive to light at night, and can play the role of light attracting fish, and improve the fish attracting efficiency of the fish catching device at night.

[0075] In a possible implementation, a plurality of water holes are evenly distributed on the spoiler baffle 200. When the water flow velocity in the river is high, the water holes can reduce the impact force of the water flow on the spoiler baffle 200, avoid the spoiler baffle 200 being scoured and damaged by excessive water flow velocity, and increase the service life of the spoiler baffle 200.

[0076] In order to guide the fishes to the fish gathering area 500, the ends of the two fences 300 facing the inside of the fishing fence 100 are set to be narrowed. At the same time, the two fishing fences 100 set to be narrowed can reduce the area of ​​the fish inlet 400, and while guiding the fishes to enter the fish gathering area 500, prevent the fishes from swimming out of the fish gathering area 500 through the fish inlet 400.

[0077] In addition, the two fences 300 have expanded openings on the sides facing away from the fish inlet 400 , which can increase the fishing area and encourage more fish to enter the fish gathering area 500 .

[0078] In addition, the fence 300 extends to the outside of the fishing fence 100, which can further increase the fishing area, allowing more fish to enter the fish gathering area 500, thereby improving the fishing efficiency.

[0079] Here, the fence 300 can be extended by adjusting the distance between two adjacent fence pieces 320, or the fishing area can be increased by increasing the number of fence pieces 320.

[0080] In addition, the fence panels 320 are connected by ropes 310 , which have good flexibility and can effectively prevent the impact of water flow on the fence 300 .

[0081] In a possible embodiment, the fish catching device further comprises a net door 700, which is rotatably connected to one of the fences 300 to open and close the fish inlet 400. When the fish in the fish gathering area 500 need to be transferred, the fish inlet 400 can be closed by the net door 700 to prevent the fish from escaping during the transfer process.

[0082] In other possible implementations, the water flow fish attracting assembly 610 includes a drain pipe 611 , a water pump assembly 612 , and a water inlet pipe 613 .

[0083] The drain pipe 611 is connected to the mounting portion 130 , and the drain pipe 611 , the water pump assembly 612 and the water inlet pipe 613 are connected in sequence. The water pump assembly 612 is configured to draw water from the river through the water inlet pipe 613 and discharge it into the fish collecting area 500 through the drain pipe 611 .

[0084] In the above embodiment, the water pump assembly 612 is started, water from the river is sucked through the water inlet pipe 613, and discharged to the fish gathering area 500 through the drain pipe 611. Some fish have the characteristic of upstream migration, and the water flow discharged from the drain pipe 611 can create a living environment suitable for fish. The power of the water pump assembly 612 can be adjusted, and the flow rate of the water flow discharged from the drain pipe 611 can be controlled to adapt to the requirements of different types of fish for the living environment, and at the same time, the water flow can be used to attract fish to enrich.

[0085] Here, the water inlet pipe 613 can be used to pump water from the outside of the fish collecting area 500, or can be used to pump tap water from the outside, and the present application has no limitation thereto. In addition, in order to ensure the installation stability of the water pump assembly 612, the water pump assembly 612 can be arranged on the shore ground.

[0086] In a possible embodiment, in order to facilitate the transfer of fish in the fish gathering area 500, the fish capturing device further includes at least one fish draining channel 800, which is connected to the fishing fence 100. The fish draining channel 800 is configured to connect the outside of the fish gathering area 500 and the fishing fence 100 after being opened.

[0087] In the above embodiment, the fish draining channel 800 is set to a normally closed state, and only needs to be opened when the fish in the fish gathering area 500 need to be transferred. After opening the fish draining channel 800, the fish can be driven away in the fish gathering area 500, prompting the fish to be transferred to the fish transport vehicle through the fish draining channel 800.

[0088] The number of fish drainage channels 800 can be selected as needed, and the present application does not limit the number of fish drainage channels 800.

[0089] In a possible implementation, the fence 300 is connected to the riverbed via an anchor rod 900. The use of the anchor rod 900 to connect the fence 300 to the riverbed can ensure a stable connection of the fence 300. The anchor rod 900 is also convenient and quick to construct, which can improve installation convenience.

[0090] The implementation principle of a fish catching device in the embodiment of the present application is as follows: the fish catching device comprises: a fishing fence 100, at least one spoiler baffle 200 and a fish attracting channel, the fish attracting channel comprises two fences 300, the fences 300 extend toward the inside of the fishing fence 100 to form a fish inlet 400, the fish attracting channel and the fishing fence 100 are surrounded by a fish gathering area 500, and the fish gathering area 500 is used to collect fish. The spoiler baffle 200 is arranged in the fish gathering area 500, and the spoiler baffle 200 is rotatably connected to at least one of the fishing fence 100 and the fish attracting channel, and the spoiler baffle 200 is configured to rotate to shift the water flow in part of the fish gathering area 500 to change the water flow environment in the fish gathering area 500. Different types of fish have different adaptability to habitats, and the above setting method can simulate the habitats of multiple fish, improve the applicability of the fish catching device, and reduce damage to fish.
