Description

Technical Field

[0001] This application relates to the field of water conservancy and hydropower engineering technology, and in particular to a fish collection workboat used in the operation of water conservancy projects. Background Technology

[0002] Currently, in the water conservancy and hydropower engineering industry, upstream fish passage systems serve as important ecological protection facilities, playing a crucial role in ensuring unobstructed fish migration routes and maintaining aquatic biodiversity. With the deepening of ecological civilization construction and increasingly stringent environmental regulations in my country, significant progress has been made in the technological research and engineering application of upstream fish passage systems. These systems are artificially assisted fish passage facilities specifically designed to address the obstruction of fish migration routes by high dams and large reservoirs. Their core function is to help fish overcome dam obstacles and complete their migration from downstream to upstream through engineering means. Compared with traditional fish passage facilities such as fishways and fish locks, upstream fish passage systems have significant advantages, including flexible deployment, adaptability to large water level fluctuations, and minimal interference with the main engineering structure, making them particularly suitable for the fish protection needs of high dam water conservancy projects.

[0003] Conventional upstream fish collection systems in water conservancy and hydropower projects use deep-water nets on both banks connected to a fish collection platform to collect fish from the water area. However, the force of the water flow often causes deformation of the deep-water nets, leading to fish escape. Furthermore, debris in the river channel can directly clog and damage the deep-water nets under the impact of the water flow.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0005] In view of this, the present application provides a fish-collecting workboat that can effectively collect fish without being affected by debris in the river channel, and is easy to lay and retrieve, effectively replacing deep-water nets and foils for water conservancy projects.

[0006] To achieve the above objectives, this application provides a fish-attracting work vessel for water conservancy engineering operations. The fish-attracting work vessel includes a hull and an electric fish-blocking system. The electric fish-blocking system includes a fish-blocking grid assembly and a pulse voltage generating device. The fish-blocking grid assembly is deployed in the river section where the hull operates, and the fish-blocking grid assembly includes a first fish-blocking grid located near the riverbank and a second fish-blocking grid located in the middle area of ​​the river section near the hull. The pulse voltage generating device is electrically connected to the first fish-blocking grid and the second fish-blocking grid, respectively, and is used to output a first pulse voltage to the first fish-blocking grid and a second pulse voltage to the second fish-blocking grid. The voltage value of the first pulse voltage is greater than the voltage value of the second pulse voltage, so as to concentrate fish in the middle area of ​​the river section near the hull through the voltage gradient formed by the first fish-blocking grid and the second fish-blocking grid.

[0007] In some embodiments of this application, the fish-gathering workboat used for water conservancy project operation further includes an anchor chain, an anchor winch, and an anchor winch fixing control system. One end of the anchor chain is fixed to the hull, the anchor winch is disposed on the hull, and the anchor winch fixing control system is disposed on the hull. The anchor winch fixing control system is used to control the anchor winch to drive the anchor chain to extend and retract, so as to dynamically control the bow and position of the fish-gathering workboat used for water conservancy project operation, so as to realize the fish-gathering boat being moored and fixed in the river channel.

[0008] In some embodiments of this application, the fish-collecting workboat used in the operation of the water conservancy project further includes a positioning module; in waters with gentle currents, the positioning module is used to control the anchor winch to anchor in order to achieve positioning in the current; in waters with rapid currents where anchoring is not possible, the anchor winch can automatically adjust the length of the anchor chain through the positioning signal of the positioning module to achieve positioning in turbulent waters.

[0010] In some embodiments of this application, the fish-collecting workboat used in the operation of the water conservancy project further includes a fish-blocking electric gate deployment and retrieval system, which includes a hull and a drive assembly; wherein, the fish-blocking electric gate assembly further includes a cable connecting the first fish-blocking electric gate and the second fish-blocking electric gate, one end of the cable is wound around the drive assembly, and the drive assembly is capable of driving the cable to be retracted into the hull or released from the hull.

[0011] In some embodiments of this application, the fish barrier electric grid deployment and retraction system further includes a guide drive shaft and a universal cable slip ring. The guide drive shaft is fixed to the center of the housing, the universal cable slip ring is disposed on one side of the guide drive shaft, the drive assembly is fixedly connected to the guide drive shaft, and one end of the cable passes around the universal cable slip ring and is electrically connected to the pulse voltage generating device.

[0012] In some embodiments of this application, the deployment and retraction of the fish barrier array has a manual mode and an automatic mode.

[0013] In some embodiments of this application, the fish-collecting workboat used in the operation of the water conservancy project also includes a ballast control system. The ballast control system uses a ballast pump to allocate ballast water in each ballast tank, thereby realizing the change of the draft of the fish-collecting workboat used in the operation of the water conservancy project, enabling the fish channel and fish collection bucket of the fish-collecting workboat used in the operation of the water conservancy project to operate at different water depths, and realizing the collection of fish under different water depth conditions.

[0014] In some embodiments of this application, the fish-collecting workboat used in the operation of the water conservancy project further includes a flow-generating system. The flow-generating system includes a flow-generating pump and a bar screen regulating gate. The flow-generating pump is used to generate directional water flow and simulate a suitable water flow environment for fish, so as to guide fish to move towards the area close to the fish-collecting workboat used in the operation of the water conservancy project. The bar screen regulating gate is connected to a drive motor through a mechanical structure. The opening and closing angle of the bar screen regulating gate is controlled by controlling the rotation angle of the drive motor, so as to adjust the flow velocity in the fish-collecting channel and fish-collecting bucket of the fish-collecting workboat used in the operation of the water conservancy project.

[0015] In some embodiments of this application, the fish-collecting workboat used in the operation of the water conservancy project further includes an electric propulsion system, which includes a propeller and a generator set. The generator set is connected to the propeller to drive the propeller to rotate, thereby realizing the propulsion and navigation of the hull.

[0016] In some embodiments of this application, the fish-collecting workboat used in the operation of the water conservancy project also includes a photovoltaic system, which is located on the top of the hull and connected to the propeller to serve as a backup power source for driving the propeller to rotate.

[0017] In some embodiments of this application, the fish-collecting workboat used for the operation of the water conservancy project also includes a power management system. The power management system intelligently allocates power equipment, thereby enabling the fish-collecting workboat used for the operation of the water conservancy project to operate under various working conditions without the need for external power.

[0018] The fish-attracting vessel for water conservancy engineering operation provided in this application includes a hull and an electric fish-blocking system. The electric fish-blocking system includes a fish-blocking grid assembly and a pulse voltage generating device. The fish-blocking grid assembly is deployed in the river section where the hull operates, and the fish-blocking grid assembly includes a first fish-blocking grid located near the riverbank and a second fish-blocking grid located in the middle area of ​​the river section near the hull. The pulse voltage generating device is electrically connected to the first fish-blocking grid and the second fish-blocking grid respectively, and is used to output a first pulse voltage to the first fish-blocking grid and a second pulse voltage to the second fish-blocking grid. The voltage value of the first pulse voltage is greater than the voltage value of the second pulse voltage, so as to concentrate fish in the middle area of ​​the river section near the hull through the voltage gradient formed by the first fish-blocking grid and the second fish-blocking grid. This application utilizes the fish-blocking electric grid assembly deployed within the river section where the vessel operates. A high-pulse voltage is output to the first fish-blocking electric grid located near the riverbank via a pulse voltage generating device, while a low-pulse voltage is output to the second fish-blocking electric grid located in the middle of the river section near the vessel (i.e., segmented control of the fish-blocking electric grid's pulse voltage output). This stimulates fish and concentrates them in the middle of the river section near the fish-collecting work vessel used in water conservancy projects, thereby gathering fish into the fish-collecting channel. This replaces traditional deep-water netting. The fish-blocking electric grid on the fish-collecting work vessel used in water conservancy projects allows debris in the river to pass through without damaging the grid, thus achieving effective fish collection. Simultaneously, the fish-collecting effect is not affected by river debris. Its convenient installation and retrieval effectively replace deep-water netting. Attached Figure Description

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] In existing technologies, the deep-water foil netting in traditional upstream fish collection systems is difficult to lay and is easily affected by water flow, resulting in gaps in the netting distribution and fish escaping. Furthermore, the deep-water foil netting in traditional upstream fish collection systems is prone to accumulating or even tearing due to the influence of various floating debris in the river.

[0035] To resolve the above issues, please refer to Figure 1 This application provides a fish-attracting work vessel for water conservancy engineering operations. The fish-attracting work vessel includes a hull 110 and an electric fish-blocking system 120. The electric fish-blocking system 120 includes a fish-blocking electric grid assembly 11 and a pulse voltage generating device 12. The fish-blocking electric grid assembly 11 is deployed in the river section where the hull 110 operates, and the fish-blocking electric grid assembly 11 includes a first fish-blocking electric grid 111 set near the riverbank and a second fish-blocking electric grid 112 set near the middle area of ​​the river section near the hull 110. The pulse voltage generating device 12 is electrically connected to the first fish-blocking electric grid 111 and the second fish-blocking electric grid 112, respectively, and is used to output a first pulse voltage to the first fish-blocking electric grid 111 and a second pulse voltage to the second fish-blocking electric grid 112. The voltage value of the first pulse voltage is greater than the voltage value of the second pulse voltage, so that the voltage gradient formed by the first fish-blocking electric grid 111 and the second fish-blocking electric grid 112 concentrates fish in the middle area of ​​the river section near the hull 110.

[0036] This application deploys the fish-blocking electric grid assembly 11 within the river section where the vessel 110 operates. The pulse voltage generating device 12 outputs a high pulse voltage to the first fish-blocking electric grid 111 located near the riverbank and a low pulse voltage to the second fish-blocking electric grid 112 located in the middle of the river section near the vessel 110 (i.e., segmented control of the output pulse voltage of the fish-blocking electric grid). This stimulates fish and concentrates them in the middle of the river section near the fish-collecting work vessel used in water conservancy projects, thereby gathering fish into the fish-collecting channel, replacing traditional deep-water nets and foils. The fish-blocking electric grids on the fish-collecting work vessel used in water conservancy projects of this invention allow debris in the river to pass through without damaging the grids, thus achieving effective fish collection. Simultaneously, the fish-collecting effect is not affected by river debris. The grids are easy to install and retrieve, effectively replacing deep-water nets and foils.

[0037] Specifically, the fish barrier electric grid assembly 11 also includes an electrode float 113, an electrode insulator 114, a cable, and a flexible thrust band 116. The cable consists of an electrode power supply branch cable 1151 and an electrode partition pulse cable 1152. The electrode float 113 is connected to the electrode insulator 114 via a clamp 117. The fish barrier electric grid is connected below the electrode insulator 114. The electrode partition pulse cable 1152 is also segmented and fixed via the clamp 117 under the electrode float 113. The corresponding positive and negative cables of the electrode partition pulse cable 1152 are connected to the electrode cable wiring holes 118 on the fish barrier electric grid through the cable, so as to achieve the purpose of alternating positive and negative polarity between adjacent fish barrier electric grids. The lower portions of two adjacent fish-blocking electric grids (e.g., two adjacent first fish-blocking electric grids 111 or two adjacent second fish-blocking electric grids 112 or adjacent first fish-blocking electric grids 111 and second fish-blocking electric grids 112) are connected by a flexible thrust band 116. The flexible thrust band 116 is made of a non-conductive material, which can prevent short circuits caused by contact between adjacent electrodes.

[0038] Depend on Figure 9 As can be seen from the typical wiring diagram of the fish barrier grid shown, the electrode partition pulse cable 1152 is connected to the pulse voltage generating device 12 (e.g., the fish barrier grid pulse power supply). Figure 9 Different connection points of the leftmost component allow for different pulse voltage adjustments in different areas. By adjusting and controlling the pulse voltage, a higher pulse voltage can be achieved in the riverbank area, while a lower pulse voltage can be achieved in the middle of the river near the fish channel 32 of the fish-gathering vessel used in the water conservancy project. This achieves the purpose of driving fish away from the riverbank and concentrating them in the fish channel 32 of the fish-gathering vessel used in the water conservancy project.

[0039] Specifically, the pulse voltage generating device 12 has multiple positive and negative connection sections. Correspondingly, each fish-blocking electric grid of the fish-blocking electric grid group 11 is divided into positive electrodes and negative electrodes. The positive electrodes of different regions (e.g., region 1 and region 2) are connected to the positive electrodes in the corresponding positive and negative connection sections through the electrode partition pulse cable 1152. The negative electrodes of different regions (e.g., region 1 and region 2) are connected to the negative electrodes in the corresponding positive and negative connection sections through the electrode partition pulse cable 1152.

[0040] In some embodiments of this application, the fish-collecting workboat used in the operation of the water conservancy project further includes a fish-blocking electric gate deployment and retrieval system 130. The fish-blocking electric gate deployment and retrieval system 130 is used to deploy and retrieval the fish-blocking electric gate assembly 11.

[0041] In some embodiments of this application, the fish barrier electric grid retraction and deployment system 130 includes a housing 21 and a drive assembly 22. The housing 21 includes a spiral guide groove 211. One end of the cable is wound around the drive assembly 22, and the drive assembly 22 can drive the cable to be retracted into or released from the spiral guide groove 211.

[0042] The main body of the fish barrier electric grid deployment and retraction system 130 of this application is the housing 21 that stores the fish barrier electric grid assembly 11. The housing 21 is made of high-strength insulating plastic and is in the shape of a roll (that is, the housing 21 is an insulating roll), which ensures that any two of the first electric grid electrode and the second electric grid electrode are isolated from each other when stored, and prevents any two of the first electric grid electrode and the second electric grid electrode from coming into contact with each other and causing a short circuit.

[0043] In some embodiments of this application, the drive assembly 22 includes a guide drive shaft 221 and a guide drive plate 222. The guide drive shaft 221 is located at the center of the spiral guide groove 211, and the guide drive plate 222 is disposed at one end of the spiral guide groove 211. The guide drive plate 222 is connected and fixed to the guide drive shaft 221.

[0044] The guide drive plate 222 includes at least one sub-guide drive plate 222. In some embodiments of this application, the guide drive plate 222 includes four sub-guide drive plates 222, which are respectively fixedly connected to the guide drive shaft 221 to divide the spiral guide groove 211 into four parts. In other embodiments, the number of guide drive plates 222 can be 1, 2, 3, 5, 6, etc.

[0045] In some embodiments of this application, the inner wall of the spiral guide groove 211 has a spiral guide (not shown). The electrode float 113 of the fish barrier electric grid assembly 11 uses the spiral guide as a guide rail. Under the external force of the guide drive plate 222, the first fish barrier electric grid 111, the second fish barrier electric grid 112, the electrode float 113, the electrode insulator 114, the cable, the flexible thrust band 116, and other components all enter the spiral guide groove 211. The electrode float 113 is on the spiral guide above the spiral guide groove 211, and the other components are all inside the spiral guide groove 211. That is, the electrode float 113 can be slidably connected to the spiral guide on the inner wall of the spiral guide groove 211 and can slide along the spiral guide. Among them, the electrode partition pulse cable 1152 and the flexible thrust band 116 are both flexible structures and can be coiled along the spiral guide groove 211. Because each layer of the spiral guide groove 211 is separated from the outside to the inside by an insulating structure (the housing 21 itself), short circuits caused by contact between adjacent fish barrier grids are prevented. Driven by the forward rotation of the guide drive plate 222, the guide drive plate 222 drives the fish barrier grid to slide along the spiral guide groove 211 from the outer layer to the inner layer until the final position.

[0046] In some embodiments of this application, the drive assembly 22 further includes a universal cable slip ring, which is disposed on one side of the guide drive shaft 221. The drive assembly 22 is fixedly connected to the guide drive shaft 221, and one end of the cable passes around the universal cable slip ring and is electrically connected to the pulse voltage generating device 12.

[0047] The electrode partition pulse cable 1152 on the innermost fish barrier grid is connected to the corresponding pulse voltage generating device 12 (i.e., pulse power supply box) via a universal cable slip ring above the housing 21. During the process of the guide drive plate 222 driving the fish barrier grid assembly 11 into the spiral guide groove 211, the electrode partition pulse cable 1152 on the innermost fish barrier grid is always directly connected to the universal cable slip ring. During the curved movement of the fish barrier grid, its electrode partition pulse cable 1152 is constantly subjected to radial rotational winding stress. After passing through the universal cable slip ring, the universal cable slip ring can effectively release this stress, preventing the cable from being damaged by long-term stress.

[0048] When the guide drive plate 222 rotates counterclockwise, each layer of fish barrier grids, driven by the guide drive plate 222, rotates outward along the guide rail on the spiral guide groove 211 in a spiral path. Through the combined effect of the above structures, the fish barrier grid assembly 11 can rotate in and out of the spiral guide groove 211, facilitating the deployment and retraction of the fish barrier grid assembly 11. During the entire deployment and operation process, no personnel are required to perform wiring operations on the fish barrier grid assembly 11.

[0049] In some embodiments of this application, the drive assembly 22 further includes a drive motor (not shown), and the guide drive shaft 221 is connected to the drive motor. The guide drive shaft 221 and the guide drive plate 222 are controlled by the frequency conversion of the drive motor, thereby realizing the frequency conversion speed regulation of the fish barrier electric grid assembly 11.

[0050] In some embodiments of this application, a fish-blocking electric grid group 11 storage device (not shown) is arranged on each of the port and starboard sides of the fish-collecting workboat used in water conservancy projects. The fish-blocking electric grid group 11 storage device centrally controls the drive motors in the two fish-blocking electric grid group 11 storage devices through the control system, thereby controlling the opening and closing of the fish-blocking electric grid group 11 in the electric grid storage device.

[0051] The fish barrier electric fence deployment and retrieval system 130 has two control modes: manual and automatic. In manual mode, the drive motors of each electric fence deployment and retrieval device can be controlled individually to perform the deployment and retrieval operations according to actual needs.

[0052] Please see Figure 10 In automatic mode, the stretching angles A1 and A2 of the electric fences, monitored by the stretching angle sensors at the outlets of the two electric fence storage devices on the port and starboard sides, are continuously fed back to the intelligent control module of the electric fence deployment and retrieval system 130. Based on the received parameters, the intelligent control module dynamically sends control commands to the electric fence deployment and retrieval device drive motor control module in real time, driving the electrodes to operate and activating electric fence deployment and retrieval devices 1 and 2. Through the dynamic adjustment of electric fence deployment and retrieval devices 1 and 2, the stretching state of the electric fence is achieved to the set target. Generally, to meet the purpose of fish collection, fish-collecting workboats used in water conservancy projects in the middle of the river ultimately achieve the set target of the electric fence stretching angle A1=A2.

[0053] In some embodiments of this application, the fish collection vessel used in the operation of the water conservancy project also includes a ballast control system 140. The ballast control system 140 uses a ballast pump to allocate ballast water in each ballast tank, thereby realizing the change of the draft of the fish collection vessel used in the operation of the water conservancy project. This allows the fish channel 32 and the fish collection bucket 33 of the fish collection vessel used in the operation of the water conservancy project to operate at different water depths, thus realizing the collection of fish under different water depth conditions.

[0054] The installation of the fish barrier electric fence group 11 in the river section is completed by the fish barrier electric fence deployment and retrieval system 130 unique to the fish collection workboat used in the operation of the water conservancy project. At the same time, with the cooperation of the ballast control system 140 of the fish collection workboat used in the operation of the water conservancy project, the fish collection workboat used in the operation of the water conservancy project adjusts the draft through the ballast control system 140, so that the fish channel 32 and the fish collection bucket 33 of the fish collection workboat used in the operation of the water conservancy project can work at different water depths, so as to realize the fish collection work under different water depth conditions.

[0055] Specifically, the ballast control system 140 on the fish-gathering vessel used in water conservancy engineering operations of the present invention uses a ballast pump to allocate ballast water in each ballast tank, thereby changing the draft of the fish-gathering vessel and enabling the fish passage 32 and fish collection bucket 33 of the fish-gathering vessel to operate at different water depths, thus achieving fish collection under different water depth conditions. Near the entrance of the fish passage 32 of the fish-gathering vessel, an extended net plate 31 is arranged. This extended net plate 31 is in the form of a hinge frame. When the fish-gathering vessel operates with a shallow ballast draft and a deep river channel, the ballast control system 140 can control the extended net plate 31 lifting motor to lower the extended net plate 31 via a traction rope 34, preventing fish collected by the fish-blocking electric fence from escaping from the bottom of the vessel.

[0056] In some embodiments of this application, the fish-gathering workboat used for water conservancy project operation further includes an anchor chain, an anchor winch, and an anchor winch fixing control system 43. One end of the anchor chain is fixed to the hull 110, the anchor winch is disposed on the hull 110, and the anchor winch fixing control system 43 is disposed on the hull 110. The anchor winch fixing control system 43 is used to control the anchor winch to drive the anchor chain to extend and retract, so as to dynamically control the bow and position of the fish-gathering workboat used for water conservancy project operation, so as to realize the fish-gathering boat being moored and fixed in the river channel.

[0057] In this embodiment, the fish-collecting workboat used for the operation of the water conservancy project includes a first anchor winch 421, a second anchor winch 422, a third anchor winch 423 and a fourth anchor winch 424, which are respectively located at the four corners of the hull 110.

[0058] The fish-gathering vessel used in this water conservancy project is secured by the anchor winch fixing control system 43. This system controls the raising and lowering of the anchor winches at the four corners of the vessel, dynamically controlling its bow and position to ensure it remains moored and fixed in the river. With the coordinated dynamic intelligent control of the anchor winch fixing control system 43 and the fish barrier electric gate deployment and retrieval system 130, the fish-gathering vessel can still achieve real-time fixed installation of the fish barrier electric gate and dynamic fixation even under the influence of water flow and wind speed in the river.

[0059] Specifically, the anchor winch fixing control system 43 of the fish gathering workboat used in water conservancy engineering operation of the present invention controls the raising and lowering of the anchor winches at the four corners of the fish gathering workboat used in water conservancy engineering operation, dynamically controls the bow and position of the fish gathering workboat used in water conservancy engineering operation, and realizes the fish gathering boat moored and fixed in the river channel.

[0060] Please see Figure 11 , Figure 11 As an automatic control method for the anchor winch fixing control system, the four anchor winches of the fish gathering workboat used in this water conservancy project are equipped with tension sensors and anchor chain tension angle sensors. After the fish-gathering workboat used in the water conservancy project anchors in the designated water area, the automatic control system is activated. It continuously analyzes and processes the sensor parameters detected by the bow sensor and the position sensor of the fish-gathering workboat through the intelligent control module of the anchor winch fixing control system 43. At the same time, combined with the feedback parameters of the four corner anchor chain tension angles Q1~Q4 from the four corner anchor chain tension angle sensors, the intelligent control module sends the anchor winch control command to the anchor winch control module. The anchor winch control module controls the four corner anchor winches (anchor winch 1 (first anchor winch 421), anchor winch 2 (second anchor winch 422), anchor winch 3 (third anchor winch 423), and anchor winch 4 (fourth anchor winch 424)) to perform actions. While the anchor winches are performing actions, the tension parameters T1~T4 sensed by the tension sensors of the four corner anchor winches are also fed back to the intelligent control module. Through comprehensive intelligent analysis and control, the position and bow status of the fish-gathering workboat used in the water conservancy project meet the preset position and bow control commands.

[0061] In some embodiments of this application, the fish-collecting workboat used in the operation of the water conservancy project further includes a positioning module; in waters with gentle or rapid currents, the positioning module is used to control the anchor winch to anchor in order to achieve positioning in the water flow; in waters with rapid currents where anchoring is not possible, the anchor winch can automatically adjust the length of the anchor chain through the positioning signal of the positioning module to achieve positioning in turbulent waters.

[0062] In this embodiment, the positioning module is a GPS / BeiDou positioning module.

[0063] The anchor winch fixing control system 43 of this application, equipped with a positioning module, can achieve automatic anchoring and fine-tuning of position. In waters with calm or turbulent currents, the anchor winches can be directly controlled to lower into the water. Through the coordinated control of four anchor winches, positioning in the current can be achieved. In waters with turbulent currents where anchoring is impossible, the anchor can be fixed in a secure position on the shore. Through positioning signals, the anchor winches automatically adjust the length of the anchor chain to achieve positioning in turbulent waters. This solution solves the problem of traditional fish collection platforms relying on manpower and experience to handle positioning, which consumes a lot of time, while avoiding various dangers in positioning operations.

[0064] In some embodiments of this application, the fish-collecting workboat used in the operation of the water conservancy project further includes a flow-generating system 150. The flow-generating system 150 includes a flow-generating pump 51 and a bar screen regulating gate 52. The flow-generating pump 51 is used to generate directional water flow and simulate a suitable water flow environment for fish, so as to guide fish to move towards the area close to the fish-collecting workboat used in the operation of the water conservancy project. The bar screen regulating gate 52 is connected to a drive motor through a mechanical structure, and the opening and closing angle of the bar screen regulating gate 52 is controlled by controlling the rotation angle of the drive motor.

[0065] In the flow-generating system 150, the flow-generating pump 51 and the bar screen regulating gate 52 work together to regulate the flow rate of the water, further promoting the fish to reach the fish collection bucket 33 after passing through the fish passage 32 of the fish collection workboat used in the operation of the water conservancy project.

[0066] Specifically, to attract fish from the fishway 32 into the fish collection hopper 33, a suitable water flow environment needs to be created. The flow generation system 150 of the fish collection vessel used in this hydraulic engineering operation uses a flow generation pump 51 combined with a bar screen regulating gate 52 to regulate the flow velocity in the fish collection channel and the fish collection hopper 33. The bar screen regulating gate 52 is connected to a drive motor through a mechanical structure, and the control of the bar screen regulating gate 52 is achieved by controlling the rotation angle of the drive motor.

[0067] Because fish naturally swim upstream, different target fish species in different river basins have different requirements for water flow velocity. The appropriate water flow parameters for these target fish species are obtained through an IoT big data platform. These parameters are then transmitted to the flow control system, which compares them with the water flow parameters detected by sensors in the fish collection channel.

[0068] When the river flow velocity in the operating section is low, the flow generation system 150 of the fish collection vessel used in this water conservancy project controls the drive motor to open the bar screen adjustment gate 52 to the maximum, and at the same time starts the flow generation pump 51. The flow generation pump 51 is dynamically and intelligently controlled to ultimately achieve the target flow velocity in the fish collection channel.

[0069] When the river flow velocity in the operating section is high, the flow generation system 150 of the fish collection workboat used in this water conservancy project shuts off the flow generation pump 51, and at the same time controls the drive motor to adjust the opening of the bar screen regulating gate 52, so as to achieve the target flow velocity based on the flow velocity in the channel.

[0070] Please see Figure 12To control the flow generation system, the human-machine interface uses a large database on an IoT cloud platform to locate various behavioral parameters of the target fish species. It displays and allows selection of the appropriate upstream flow velocity parameter V for the target fish in that area. Simultaneously, the IoT cloud platform transmits the flow velocity parameter V from its database to the flow generation control system. At the same time, it collects parameters from the flow sensors in the fish passage and transmits them to the flow generation control system. The system compares the obtained flow parameters with those detected by sensors in the fish collection channel. If the flow velocity sensor parameter TV in the fish collection channel is less than the appropriate upstream flow velocity V for the target fish, the flow generation pump is activated, the screen gate is fully opened, and the pump speed is dynamically and intelligently adjusted to ensure the flow velocity in the fish collection channel meets the requirement of V. If the flow velocity sensor parameter TV in the fish collection channel is greater than the appropriate upstream flow velocity V for the target fish, the flow generation pump is deactivated, and the screen gate is dynamically and intelligently adjusted to ensure the flow velocity in the fish collection channel meets the requirement of V.

[0071] In some embodiments of this application, the fish-collecting workboat used for the operation of the water conservancy project further includes an electric propulsion system 190, which includes a propeller 61 and a propulsion generator set 62. The propulsion generator set 62 is connected to the propeller 61 to drive the propeller 61 to rotate, thereby realizing the propulsion and navigation of the hull 110.

[0072] The fish-collecting vessel used in this water conservancy project employs a twin-engine, twin-propeller electric propulsion system for both propulsion and navigation. During navigation, two generator sets provide power to the propulsion system. Protective covers are installed on the two propellers 61 to prevent the impact of fish barriers and anchor chains. A variable-pitch, slewing electric propulsion system 190 is used to integrate speed regulation and steering, reducing space requirements.

[0073] In some embodiments of this application, the fish-collecting workboat used for the operation of the water conservancy project also includes a photovoltaic system 170, which is located on the top of the hull 110 and connected to the propeller 61 to serve as a backup power source for driving the propeller 61 to rotate.

[0074] Among them, the electricity generated by the solar photovoltaic panel 71 on the top of the fish collection workboat used in the operation of the water conservancy project is used as a backup energy source, and the electrical energy is stored in the battery through the photovoltaic control panel of the photovoltaic system 170.

[0075] In some embodiments of this application, the fish-collecting workboat used for the operation of the water conservancy project also includes a power management system 180 installed in the wheelhouse 75. The power management system 180 intelligently allocates power equipment, thereby enabling the fish-collecting workboat used for the operation of the water conservancy project to operate under various working conditions without the need for external power.

[0076] The fish-gathering vessel used in this water conservancy project employs a twin-engine, twin-propeller electric propulsion system for propulsion and navigation. During navigation, two generator sets generate electricity to power the propulsion system. The electricity generated by the solar photovoltaic panels 71 on the top of the vessel serves as backup energy, and is stored in batteries via the photovoltaic control panel of the photovoltaic system 170. Once the fish barrier is installed and the vessel is secured, and it enters the fish-gathering operation state, the generator sets on the vessel cease operation. Instead, the stored energy in the batteries is used to generate alternating current to power the pulse power supply (pulse voltage generator 12) for the fish barrier, the fish barrier deployment / retraction system 130, and the anchor winch fixing control system 43. Since the fish barrier electric gate deployment and retrieval system 130 and the anchor winch fixing control system 43 consume less energy for their respective system control and operation after the fish gathering workboat used in water conservancy projects enters the fish gathering operation state, the main power supply in this state is to power the fish barrier electric gate pulse power supply.

[0077] Specifically, during ship navigation: The first switches ACB1 and ACB2 of the power management system 180 are both closed, and the first switch ACB4 is open. The two generator sets can then supply power to the two electric propulsion systems 190, since only these two systems require power. Based on system analysis of the electrical load and power supply status, the photovoltaic system 170 does not need to be connected to the power grid. At this time, the first switch ACB3 is open, and the second switches KM1 and KM2 are closed. The photovoltaic system 170 stores the electricity generated by the solar photovoltaic panels 71 in the battery, which is in a charging state.

[0078] Please see Figure 13 For power management strategies, the system acquires the status of system equipment for the current time period, including power consumption and generation status. Power consumption status includes the power and current consumption of each electrical device and system, while generation status includes the power and current supplied by generator set 1, generator set 2, and the photovoltaic system. Based on the current status of the electrical devices, the system determines the load of the electrical devices under the new status, compares the load of the electrical devices under the new status with the capacity of the generators, and executes a series of operations to enable or disable power supply for the relevant generators.

[0079] Please see Figure 8During fish-attracting operation: the two electric propulsion systems 190 are not used, while the anchor winch system, the fish barrier electric grid system, and the fish barrier electric grid deployment and retraction system 130 are dynamically used. Based on system analysis of power load and power supply status, the photovoltaic system 170 is connected to the power supply network. The first switches ACB1 and ACB2 are open, the first switches ACB3 and ACB4 are closed, and the second switches KM1 and KM2 are closed. During the day when there is sufficient sunlight, the photovoltaic system 170 supplies part of the generated electricity to the power-consuming system and equipment through the first switch ACB3, while storing the remaining energy in the battery. At night when there is insufficient sunlight, the photovoltaic system 170 converts the stored energy in the battery into conventional AC power and supplies it to the power-consuming system and equipment through the first switch ACB3. When there is insufficient sunlight for a long period of time, the energy stored in the battery is insufficient to maintain the power supply of the power system and equipment. At this time, the power management system 180 controls the first generator set 73 to start. By closing the first switch ACB1, the power supply to the power system and equipment is turned on, and at the same time, the first switch ACB3 is used to charge the battery of the photovoltaic system 170 to prevent the battery from being depleted and affecting its lifespan, thus protecting the battery.

[0080] This power management system intelligently allocates power equipment, enabling the fish-collecting workboats used in this water conservancy project to operate under various working conditions without the need for external power.

[0081] Since the fish-blocking electric gate deployment system 130 and the anchor winch fixing control system 43 consume relatively little energy for their respective system control and operation after the fish-collecting workboat used in the water conservancy project enters the fish-collecting operation state, they mainly supply power to the fish-blocking electric gate pulse power supply in this state. Because the original design intent of this solar photovoltaic system 170 is to meet the day and night power supply needs of the fish-collecting workboat used in the water conservancy project during fish-collecting operation, during the day when there is sufficient sunlight, part of the electrical energy from the solar photovoltaic panels 71 is inverted into AC power to directly supply the ship's power supply equipment (mainly the pulse voltage generating device 12), and the other part of the electrical energy is stored in the battery. When it is night or when there is insufficient sunlight, the battery discharges and inverts into AC power to supply external energy. When there is prolonged cloudy or rainy weather and the power generation capacity of the solar photovoltaic system 170 is limited, the power management system 180 can automatically start the first generator set 73 and the second generator set 74 to generate electricity and charge the battery bank. This allows the fish-collecting workboat used in the water conservancy project to operate under various working conditions without the need for external power. By utilizing the photovoltaic system 170 as the primary clean energy source during the fish-gathering operation, the problem of power supply is greatly solved. It also reduces the cost associated with fuel consumption during operation. During operation, combined with the function of the fish-blocking electric fence, and the lighting, baiting, and current-generating devices within the fish-gathering hopper 33, the efficiency of fish gathering is significantly improved.
