[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0022] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0023] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0024] The following is an explanation of a fish changing station provided in an embodiment of the present application through a specific example. Figure 1 A schematic diagram of a fish exchange station system for a dam provided in an embodiment of the present application; Figure 2 A schematic diagram of a fish gathering area provided in an embodiment of the present application.

[0025] like Figure 1 The fish exchange station comprises a fish gathering station, a fish release station, a station building, and a central control room. Each group of fish gathering and fish release stations is separated by a weir, and each station is equipped with a corresponding station building. The central control room can be located in any location, as long as it can achieve remote communication with the equipment in the fish gathering and fish release stations.

[0026] like Figure 2 The fish collection and exchange station is equipped with a fish collection area. A fish attracting device 1 is installed at the exit of a fish passage in the fish collection area, which is used to guide fish through the passage and into a fish exchange box 3 mounted on a first base 2. The fish collection area is connected to the water area via the passage. The fish attracting device 1 attracts fish through the passage and into the fish exchange box 3 in the fish collection area, thereby collecting the fish. The fish collection and exchange station is also equipped with a permeable plate 5 that serves to block the fish collection area from the exterior wall, and a water supply pipe 6 that is used to supply water to the fish collection area.

[0027] A first winch 4 is installed in the station building. The first winch 4 is located at a first target position corresponding to the exit of the fish passage in the station building. The first winch 4 is connected to the first base 2. The first winch 4 is used to lift the fish changing box 3 on the first base 2 and move the fish changing box 3 to the target fish transport vehicle. After the fish are collected in the fish changing box 3, the first winch 4 lifts the fish changing box 3 out of the fish collection area and moves the fish changing box 3 to the target fish transport vehicle. Figure 3 The target fish transport vehicle is a schematic diagram of the target fish transport vehicle provided in the embodiment of the present application. The target fish transport vehicle transports the fish exchange box 3 from the fish collection and exchange station to the fish release and exchange station along the estimated transport route.

[0028] The fish-exchanging station is provided with a releasing area and a second hoist arranged at a second target position corresponding to the releasing area. The second hoist is connected to the second base and is used to release the fish in the fish-exchanging box placed on the second base to the releasing area. The connection relationship between the second hoist and the second base, and the fish-exchanging box is similar to the connection relationship between the first hoist 4 and the first base 2, and the fish-exchanging box 3. After the target fish transport vehicle transports the fish-exchanging box 3 to the target position of the fish-exchanging station, the fish-exchanging box 3 is moved to the second base. The second hoist is always connected to the second base, and then the second hoist is operated to move the fish-exchanging box 3 to the releasing area, and the fish in the fish-exchanging box 3 are poured into the releasing area. The fish-exchanging box 3 is connected to the first base 2, the second base, and the target fish transport vehicle by positioning buckles, so that the fish-exchanging box 3 is placed on the first base 2, the second base, and the target fish transport vehicle and does not move.

[0029] The fish-attracting device, the first hoist, and the second hoist are all remotely connected to a central control device located in the central control room. The central control device is also remotely connected to the target fish transport vehicle. The operation of the fish-attracting device, the first hoist, the second hoist, and the target fish transport vehicle is all controlled by the central control device. For example, the central control device can be a computer, mobile phone, or other electronic device with remote control capabilities.

[0030] Therefore, fish changing is achieved by automatically transporting the fish changing box, which optimizes the fish changing process. No human intervention is required throughout the process, which improves the overall fish changing efficiency and reduces labor costs.

[0031] In summary, in this embodiment, the fish changing station includes: a fish gathering and changing station, a fish releasing and changing station, a station building and a central control room; the fish gathering and changing station is provided with a fish gathering area, and a fish attracting facility is provided at the exit of the fish passage in the fish gathering area, for allowing the fish to pass through the fish passage into the fish changing box arranged on the first base; a first winch is provided in the station building, and the first winch is arranged at a first target position corresponding to the exit of the fish passage in the station building, and the first winch is connected to the first base to lift the fish changing box on the first base through the first winch, and move the fish changing box to the target fish transport vehicle; the fish releasing and changing station is provided with a releasing area, and a second winch arranged at a second target position corresponding to the releasing area, and the second winch is connected to the second base, for releasing the fish in the fish changing box placed on the second base to the releasing area; the fish attracting facility, the first winch and the second winch are all remotely communicated with the central control equipment arranged in the central control room. Therefore, fish changing is achieved by automatically transporting the fish changing box, which optimizes the fish changing process. No human intervention is required throughout the process, which improves the overall fish changing efficiency and reduces labor costs.

[0032] In another embodiment of the present application, Figure 4 This is a station building internal operation diagram provided by the embodiment of this application. Figure 4As shown, the station building is also equipped with: a transport vehicle 8, which is remotely connected to the central control equipment for controlling the transport vehicle 8 to transport the fish exchange box to the target fish transport vehicle along the first preset trajectory, and to transport the empty fish exchange box to the first base 2 along the second preset trajectory.

[0033] After the target fish transport vehicle transports the fish changing box to the fish releasing and changing station, the transport vehicle 8 in the fish releasing and changing station transports the fish changing box on the target fish transport vehicle to the second base on the second winch, so that the second winch moves the fish changing box.

[0034] Therefore, only the fish boxes need to be moved for replacement each time, and there is no need to dump the fish boxes outside the water area, which avoids mechanical damage to the fish and stimulation of rapids during the dumping process and improves the overall fish replacement efficiency.

[0035] In summary, in this embodiment, the station building is further equipped with a transport vehicle, which is remotely connected to the central control device and is used to control the transport vehicle to transport the fish exchange box along a first preset trajectory to the target fish transport vehicle, and to transport the empty fish exchange box along a second preset trajectory to the first base. This improves overall fish exchange efficiency.

[0036] In another embodiment of the present application, the first hoist is a single hoist, and the single hoist is connected to a suspension portion fixedly arranged on the first base through a single suspension steel cable.

[0037] The first hoist 4 only needs to move the fish changing box 3 up and down, and a single hoist can achieve this function.

[0038] In another embodiment of the present application, the second winch is a double winch, which is connected to two preset connection parts on the second base through two suspension steel cables respectively, and is used to control the tilt of the fish box placed on the second base through the second base to release fish.

[0039] In addition to moving the fish changing box 3 up and down, the second winch also needs to tilt the fish changing box 3 underwater at the discharge point. A double winch can achieve this function.

[0040] Figure 5 Schematic diagram of the second hoist provided in the embodiment of the present application. Figure 5 As shown, the front hoist and the rear hoist in the second hoist run in opposite directions to dump the fish in the fish box in the release area.

[0041] In summary, in this embodiment, the second winch is a dual winch, each connected to two pre-set connection portions on the second base via two suspension cables. The dual winch is used to control the tilting of the fish box placed on the second base via the second base to release the fish. This allows the fish in the fish box to be dumped in the release area.

[0042] In another embodiment of the present application, Figure 6 This is a schematic diagram of a fish changing box provided in an embodiment of the present application. Figure 6 As shown, the fish changing box 3 includes: a box body 31, a cover plate 32 provided at the opening of the box body 31, and an Internet of Things module 33 provided in the box body, and the Internet of Things module 33 is remotely connected to the central control device. Among them, the lower part of the box body 31 is a base, and the fish changing box 3 is connected to the base by a buckle.

[0043] The box body 31 is connected to one side of the cover plate 32. When the fish changing box 3 is placed in water, the cover plate 32 will open outward due to the buoyancy. When the fish changing box 3 is out of water, the cover plate 32 will close and cover the box body 31 due to the force of gravity. The fish changing box 3 is placed on the base of the target fish transport vehicle. The base of the target fish transport vehicle supplies power to the Internet of Things module 33, and the Internet of Things module 33 starts working to realize functions such as sending positioning coordinates to the central control device. On other bases, there is no power supply and the Internet of Things module 33 does not work. Among them, the Internet of Things module 33 is installed in a waterproof setting.

[0044] In summary, in this embodiment, the fish changing box includes: a box body, a cover plate provided at the opening of the box body, and an Internet of Things module provided in the box body, and the Internet of Things module is remotely connected to the central control device to achieve intelligent box control.

[0045] In another embodiment of the present application, Figure 7 This is a schematic diagram of another fish gathering area provided in an embodiment of the present application. Figure 7 As shown, a fish monitoring device 7 is provided at the entrance of the fish passage to monitor the fish schools passing through the fish passage. The fish monitoring device 7 is also remotely connected to the central control device for communication.

[0046] In summary, in this embodiment, a fish monitoring device is installed at the entrance of the fish passage to monitor the fish passing through the passage. The fish monitoring device is also remotely connected to the central control device. Thus, the fish passing through the fish passage can be accurately monitored by the fish monitoring device.

[0047] In another embodiment of the present application, the fish passage monitoring device 7 includes at least: a fish identification device, which is remotely connected to the central control device for communication, and the fish identification device is used to monitor the fish passage in real time to obtain the number and type of fish in the fish passage.

[0048] The central control device is used to control the first winch to lift the fish changing box on the first base when the number and type of fish meet the preset trigger conditions.

[0049] In summary, in this embodiment, the fish passage monitoring device includes at least a fish identification device, which is remotely connected to the central control device for real-time monitoring of the fish passage to determine the number and species of fish in the passage. The central control device is configured to control the first winch to raise the fish exchange box on the first base when the number and species of fish meet a preset trigger condition. This allows for accurate monitoring of fish schools in the passage.

[0050] In another embodiment of the present application, the fish luring facility 1 includes: at least one type of fish luring facility among water flow fish luring facilities, bait fish luring facilities and light fish luring facilities.

[0051] The following is an explanation of a fish-changing method provided in an embodiment of the present application through a specific example. Figure 8 This is a flow chart of a fish changing method provided in an embodiment of the present application, which is applied to the central control equipment in the fish changing station. Figure 8 As shown, the method includes: S101. Control the fish attracting facilities of the fish gathering and exchanging station so that the fish school passes through the fish passage in the fish gathering area and enters the fish exchanging box provided on the first base.

[0052] After the fish exchange work begins, turn on the fish attracting facilities of the fish gathering and exchanging station to attract the fish into the fish exchange box.

[0053] S102: Control the first winch to lift the fish exchange box on the first base, and move the fish exchange box to the target fish transport vehicle, so that the target fish transport vehicle transports the fish exchange box from the fish gathering and fish exchange station to the fish releasing and fish exchange station.

[0054] After the fish have gathered in the fish exchange box, the first winch is controlled to lift the fish exchange box out of the fish gathering area, and the transport vehicle is controlled to transport the fish exchange box along a first preset trajectory to the target fish transport vehicle. The target fish transport vehicle is then controlled to transport the fish exchange box from the fish gathering and exchange station to the fish release and exchange station along the estimated transport route.

[0055] Furthermore, the transport vehicle is controlled to transport the empty fish-changing box to the first base along a second preset trajectory.

[0056] S103, controlling the second winch to release the fish in the fish changing box placed on the second base to the releasing area.

[0057] After the target fish transport vehicle transports the fish exchange box to the fish release and exchange station, the transport vehicle at the fish release and exchange station is controlled to move the fish exchange box on the target fish transport vehicle to the second base on the second winch. The second winch is then controlled to release the fish in the fish exchange box placed on the second base to the release area.

[0058] Therefore, fish changing is achieved through automated handling of fish changing boxes, which optimizes the fish changing process. No human intervention is required throughout the process, which improves the overall fish changing efficiency and reduces labor costs.

[0059] In summary, in this embodiment, the fish attracting facilities at the fish gathering and exchanging station are controlled to allow fish to pass through the fish passage in the fish gathering area and enter the fish exchanging box located on the first base. The first winch is controlled to lift the fish exchanging box on the first base and transport it to the target fish transport vehicle, which then transports the fish exchanging box from the fish gathering and exchanging station to the fish releasing and exchanging station. The second winch is controlled to release the fish in the fish exchanging box on the second base to the releasing area. Thus, by automating the transport of the fish exchanging box, fish exchanging is achieved, optimizing the fish exchanging process. This eliminates the need for human intervention, improves overall fish exchanging efficiency, and reduces labor costs.

[0060] In another embodiment of the present application, Figure 9 This is a flow chart of another method for changing fish provided in the embodiment of the present application.
