Description

Technical Field

[0001] This invention relates to the field of operation and maintenance equipment technology for solar-fishery complementary photovoltaic power plants, and in particular to a lifting water mist bird deterrence and cleaning linkage system. Background Technology

[0002] With the large-scale development of the photovoltaic new energy industry, solar-aquaculture complementary photovoltaic power stations, as a three-dimensional resource development model of "power generation on water and aquaculture below water," have been widely promoted and applied in my country's freshwater aquaculture areas due to their advantages of high land utilization and outstanding comprehensive benefits. The photovoltaic module arrays of solar-aquaculture complementary photovoltaic power stations are deployed above open water surfaces, and the surrounding waters provide ample foraging and roosting environments for birds. Consequently, bird damage has become a core pain point affecting the power station's power generation efficiency, operational safety, and module lifespan.

[0003] Birds perching on and defecating on photovoltaic panels can directly block the sunlight-receiving surface, significantly reducing the power generation efficiency of the modules. Dried bird droppings are corrosive and can damage the coating layer on the photovoltaic panel surface. Furthermore, localized shading caused by bird droppings can trigger hot spot effects on the photovoltaic modules, potentially leading to permanent damage and long-term economic losses for the power station. Currently, the industry mainstream solutions for bird control in solar-aquaculture hybrid power plants are rotating optical bird deterrents and ultrasonic bird deterrents. Rotating solar bird deterrents use a motor to drive a reflective lens to rotate, using flashing light to interfere with birds' vision and drive them away. However, this method is singular, relying solely on static optical stimulation, making birds highly adaptable. The bird deterrent effect diminishes significantly with long-term use and is essentially ineffective in low-light conditions such as nighttime or cloudy days. Ultrasonic bird deterrents use high-frequency sound waves to stimulate the birds' auditory system, but in solar-aquaculture hybrid scenarios, the vast water surface makes high-frequency sound waves easily reflected and absorbed, severely limiting the effective coverage area. Similarly, birds easily adapt, and the bird deterrent effect declines over time. The two bird-repelling solutions mentioned above only have a single function of driving away birds and cannot address bird droppings and accumulated dust already attached to the surface of photovoltaic panels, thus failing to solve the problem of hot spot effects caused by bird droppings at its root. For cleaning bird droppings and accumulated dirt on the surface of photovoltaic panels, existing aquaculture-solar hybrid power stations mostly rely on regular manual cleaning or automated cleaning machines. Manual cleaning relies on workers using handheld high-pressure water guns and long-handled brushes for water-based operations, which presents high safety risks, low cleaning efficiency, and high maintenance costs. Furthermore, it is a reactive, post-incident treatment and cannot prevent damage to the components caused by birds' droppings.

[0004] Existing automatic cleaning machines can walk along the surface of photovoltaic panels to complete the cleaning operation. Although this improves the level of automation, the cleaning operation and bird deterrence operation are independent of each other and there is no matching linkage control logic. It is impossible to achieve a closed-loop process of "bird deterrence-cleaning". The stains left after bird deterrence cannot be cleaned in time, and there is still a safety hazard of hot spot effect. Furthermore, most of the existing cleaning equipment operates in an independent mode and cannot achieve coordinated control with the bird deterrence system. The level of automated operation and maintenance is low and it is difficult to adapt to the large-area, decentralized photovoltaic array layout of fishery-solar complementary power stations.

[0005] In summary, existing bird control and cleaning technologies in solar-aquaculture hybrid power plants are fragmented. They cannot achieve long-term, stable bird damage control through dynamic bird control, nor can they automate the linkage between bird control and cleaning operations. Consequently, they fail to comprehensively address a range of problems caused by bird damage, such as hot spots on modules, reduced power generation efficiency, and shortened lifespan. Therefore, developing an integrated system that combines long-term bird control with coordinated cleaning functions has become a pressing technical challenge in the operation and maintenance of solar-aquaculture hybrid power plants. Summary of the Invention

[0006] The purpose of this invention is to provide a lifting water mist bird deterrence and cleaning linkage system. By combining lifting action with water mist spraying in a composite dynamic bird deterrence method, it solves the problems of birds easily adapting to traditional bird deterrence methods and rapid decline in effectiveness. At the same time, it realizes the automated linkage of bird deterrence and cleaning operations through an intelligent control system.

[0007] In accordance with the above objectives, the present invention provides a lifting-type water mist bird deterrence and cleaning linkage system, comprising a lifting-type water mist bird deterrence device, a photovoltaic panel cleaner, and an intelligent control system; multiple lifting-type water mist bird deterrence devices are installed at the edges of each section of the photovoltaic array, and each lifting-type water mist bird deterrence device is connected to a water supply filtration system via a water supply pipeline; both the lifting-type water mist bird deterrence device and the photovoltaic panel cleaner are communicatively connected to the intelligent control system, which controls the lifting-type water mist bird deterrence device to complete the bird deterrence operation of lifting and water mist spraying, and sends a start cleaning command to the photovoltaic panel cleaner after the bird deterrence operation is completed.

[0008] Furthermore, each of the aforementioned lifting water mist bird repellent devices includes a linear actuator, a nozzle, and a solenoid valve; the bottom end of the linear actuator is fixedly installed on the top end of the photovoltaic support frame, and the top end of the linear actuator is fixedly connected to the nozzle; the solenoid valve is installed in series on the water supply pipeline of the corresponding lifting water mist bird repellent device, and the solenoid valve is electrically connected to the intelligent control system.

[0009] Furthermore, the photovoltaic panel cleaner includes a cleaning roller brush and a drying module. Linear guide rails are symmetrically installed along the edge of the photovoltaic panel frame. The two ends of the cleaning roller brush and the drying module are respectively mounted on the sliders of the linear guide rails via an adaptive adjustment mechanism. The adaptive adjustment mechanism includes a fixed frame, and a mounting block is slidably installed inside the fixed frame. A buffer spring is installed between the top of the mounting block and the top of the inside of the fixed frame. The cleaning roller brush and the drying module are mounted side by side on two mounting blocks, and a motor for driving the cleaning roller brush to rotate is fixedly installed on the outer side of one of the mounting blocks.

[0010] Furthermore, a guide post is installed inside the fixed frame, the mounting block is slidably mounted on the guide post, and the buffer spring is sleeved on the outside of the guide post.

[0011] Furthermore, the drying module includes a drying roller with absorbent cotton on its outer side. Both the drying roller and the cleaning roller are rotatably mounted on the mounting block, and the outer ends of the drying roller and the cleaning roller are connected by a gear mechanism.

[0012] Furthermore, the water supply filtration system includes a water intake pump, a filter, an automatic backwash control unit, and an automatic drain valve; the water intake pump is submerged and installed underwater in a clear area of ​​the fishpond; the filter is connected in series on the outlet pipe of the water intake pump; the automatic drain valve is installed on the pipe near the water surface, and the automatic drain valve is electrically connected to the intelligent control system.

[0013] Furthermore, the intelligent control system includes a main controller, a vision sensor, a lifting drive module, a nozzle control module, and a communication module; the output of the lifting drive module is electrically connected to the linear actuator of each lifting water mist bird deterrent device; the output of the nozzle control module is electrically connected to the solenoid valve; and the vision sensor is electrically connected to the main controller through the communication module.

[0014] Furthermore, it also includes a power supply system, which is electrically connected to the lifting water mist bird deterrent device, the water supply filtration system, the photovoltaic panel cleaner, and the intelligent control system.

[0015] Furthermore, the photovoltaic array is rotatably mounted on the top of the photovoltaic support frame via a bottom support frame. The top of the photovoltaic support frame is provided with a mounting base. The end of the bottom support frame is mounted on the mounting base via a bearing. An electric push rod is hinged between one side of the photovoltaic support frame and the bottom support frame. The electric push rod is electrically connected to the intelligent control system.

[0016] Furthermore, the cleaning roller is made of microfiber cloth or sponge roller.

[0017] The technical solution of this invention relies on a composite dynamic bird-repelling method combining lifting and lowering movements with water mist spraying to achieve long-term and stable active bird pest control. This reduces the risks of photovoltaic panels being shaded, corroded, and experiencing hot spots caused by birds staying and excreting. The intelligent control system automatically triggers the photovoltaic panel cleaner to start cleaning operations after the bird-repelling operation is completed. This not only promptly removes residual bird droppings, dust, and other stains after bird repelling, but also simultaneously handles water droplets condensed on the photovoltaic panel surface after water mist spraying. This completely avoids the safety hazards of residual stains and secondary hot spots caused by water droplets due to the lag in traditional manual cleaning and the lack of linkage between automatic and automated cleaning. It achieves unmanned and automated management of the entire bird repelling and cleaning process, adapting to the large-area, distributed floating photovoltaic array layout of fishery-solar complementary power stations. This significantly reduces the safety risks and maintenance costs of floating operations, effectively ensures the power generation efficiency and service life of photovoltaic modules, and significantly improves the operational stability and overall economic benefits of the power station.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] like Figures 1-3 As shown, the present invention provides a lifting water mist bird repelling and cleaning linkage system, including a lifting water mist bird repelling device 3, a photovoltaic panel cleaner and an intelligent control system.

[0027] Multiple lifting-type water mist bird deterrent devices 3 are installed at the edges of each section of the photovoltaic array. Specifically, they can be evenly distributed along the edges of the photovoltaic array, or they can be densely distributed in areas with high bird incidence in the power station. Each lifting-type water mist bird deterrent device 3 is connected to the water supply and filtration system through the water supply pipeline 8, which provides the high-pressure water source required for atomization spraying. Both the lifting-type water mist bird deterrent device 3 and the photovoltaic panel cleaner are connected to the intelligent control system. The intelligent control system is used to control the lifting-type water mist bird deterrent device 3 to complete the bird deterrent operation of lifting and water mist spraying, and after all bird deterrent operations are completed, it sends a start cleaning command to the photovoltaic panel cleaner to control the photovoltaic panel cleaner to complete the cleaning operation on the surface of the photovoltaic panel 1.

[0028] Each lifting-type water mist bird repellent device 3 includes a linear actuator 301, a nozzle 302, and a solenoid valve. In this embodiment, the linear actuator 301 is an electric telescopic rod, and the bottom end of the linear actuator 301 is fixedly installed on the top end of the photovoltaic support frame 2. The top end of the linear actuator 301 is fixedly connected to the nozzle 302. The solenoid valve is installed in series on the water supply pipe 8 of the corresponding lifting-type water mist bird repellent device 3. The control end of the solenoid valve is electrically connected to the intelligent control system, which independently controls the solenoid valve of each lifting-type water mist bird repellent device 3, thereby realizing the start and stop of the nozzle 302 and the control of the water supply pressure. In order to be able to manage the water supply pipe 8 so that it can adapt to the extension and retraction of the electric telescopic rod, a winding reel 5 is rotatably installed on the photovoltaic support frame 2. The water supply pipe 8 is wound on the winding reel 5. A torsion spring is connected between the winding reel 5 and the photovoltaic support frame 2, so that when the electric telescopic rod drives the nozzle 302 to descend, the water supply pipe 8 can automatically wind onto the winding reel 5.

[0029] In this embodiment, the linear actuator 301 is an electric push rod with an effective stroke of 1m. It can be adjusted on-site according to the size and installation height of the photovoltaic panel 1 to ensure that the nozzle 302 can completely cover the upper surface area of ​​the photovoltaic panel 1 after it is raised, achieving bird repellency and water mist coverage without dead angles. The nozzle 302 in this embodiment is a multi-hole pressurized atomizing nozzle, which can achieve a large-area bird repellency coverage and can also initially wet the surface of the photovoltaic panel 1 with water mist to soften the dried bird droppings, making it easier for subsequent cleaning operations. The multi-hole pressurized atomizing nozzle is existing technology and will not be described in detail here.

[0030] The photovoltaic panel cleaner includes a cleaning roller brush 10 and a drying module. Linear guide rails 12 are symmetrically installed on the left and right edges of the photovoltaic panel 1 frame. The linear guide rails 12 are arranged along the length of the photovoltaic panel 1 to enable continuous operation of the cleaner. The two ends of the cleaning roller brush 10 and the drying module are respectively mounted on the slider of the linear guide rail 12 through an adaptive adjustment mechanism 4, so that the cleaning roller brush 10 and the drying module can move back and forth along the linear guide rail 12 on the surface of the photovoltaic panel 1. At the same time, the adaptive adjustment mechanism 4 can compensate for the flatness error of the surface of the photovoltaic panel 1 and the height difference of adjacent photovoltaic panels 1, ensuring that the cleaning roller brush 10 and the drying module are always in close contact with the surface of the photovoltaic panel 1.

[0031] The adaptive adjustment mechanism 4 includes a fixed frame 401, an mounting block 402 slidably mounted inside the fixed frame 401, a guide post 404 mounted inside the fixed frame 401, the mounting block 402 slidably mounted on the guide post 404, a buffer spring 403 sleeved on the outside of the guide post 404, the buffer spring 403 abutting between the top of the mounting block 402 and the top of the inside of the fixed frame 401, providing clamping force and buffering margin for the cleaning roller brush 10 and the drying module; the cleaning roller brush 10 and the drying module are rotatably mounted side by side on two mounting blocks 402, and a motor 9 for driving the cleaning roller brush 10 to rotate is fixedly mounted on the outside of one of the mounting blocks 402. The drying module includes a drying roller 11 with absorbent cotton on its outer side. The drying roller 11 is connected to the outer end of the sweeping brush 10 via a gear mechanism 405. When the motor 9 drives the sweeping brush 10 to rotate, the drying module can be driven to rotate via the gear mechanism 405, realizing the linkage between the drying roller 11 and the sweeping brush 10. Figure 2 As shown, the gear mechanism 405 in this embodiment includes a first gear, an intermediate gear, and a second gear. The first gear is fixedly mounted on the rotating shaft of the cleaning roller brush 10, the second gear is fixedly mounted on the rotating shaft of the drying roller 11, and the intermediate gear is rotatably mounted on the mounting block 402. Both the first gear and the second gear mesh with the intermediate gear for transmission. The cleaning roller brush 10 cleans the stains on the surface of the photovoltaic panel 1; the drying module can simultaneously wipe away water droplets on the surface of the photovoltaic panel 1 after cleaning, avoiding the secondary hot spots caused by the lens effect due to water droplet residue.

[0032] In this embodiment, the cleaning roller brush 10 is made of microfiber cloth, which has good flexibility and cleaning ability, and can effectively remove stains such as bird droppings and dust, without damaging the surface of the photovoltaic panel 1; in other optional embodiments, the cleaning roller brush 10 can also be made of sponge roller material.

[0033] This system also includes a water supply filtration system, which comprises a water intake pump, filter 6, and an automatic drain valve. The water intake pump is a submersible pump, installed underwater in a clear area of ​​the fishpond to draw raw water from the fishpond as the system's water source, making full use of the water resources of the solar-fishery power station and reducing water supply costs. Filter 6 is connected in series on the outlet pipe of the water intake pump. Filter 6 can filter impurities such as aquatic plants, silt, and plankton in the fishpond water, ensuring that the nozzles of nozzle 302 are not clogged and guaranteeing stable atomization. The automatic drain valve is installed at the lowest point of the pipeline and is electrically connected to the intelligent control system. It is used to drain residual water in the pipeline during low temperatures in winter to prevent the pipeline from freezing and cracking.

[0034] The intelligent control system includes a main controller, a vision sensor, a lifting drive module, a nozzle 302 control module, and a communication module. The main controller is a PLC controller, fixedly installed in the central control cabinet of the power station, serving as the control core of the system. The output of the lifting drive module is electrically connected to the linear actuator 301 of each lifting water mist bird deterrent device 3, used to output drive signals to control the rising, stopping, and lowering actions of the linear actuator 301. The output of the nozzle 302 control module is electrically connected to the solenoid valve, used to control the start / stop, spray duration, and spray pressure of the corresponding nozzle 302. The vision sensor is electrically connected to the main controller through the communication module, used to establish a wireless communication link with the photovoltaic panel cleaner, realizing bidirectional transmission of commands and status signals.

[0035] The intelligent control system also integrates a special working condition processing module, which is electrically connected to the main controller to realize special working condition control logic in multiple scenarios: When the ambient temperature sensor connected to the main controller detects that the ambient temperature is below 5°C, the main controller controls all automatic drain valves to open through the special working condition processing module to drain the residual water in the pipeline and nozzle 302. Bird deterrence is achieved by controlling the mechanical dynamic lifting and lowering of the linear actuator 301, while avoiding the pipeline from freezing and cracking due to low temperature; When the system switches to the night bird deterrence mode, all solenoid valves are closed, and only the linear actuator 301 is controlled to perform lifting and lowering actions according to a preset cycle. The dynamic shadow of the linear actuator 301 during lifting and lowering is used to deter birds, avoiding prolonged dampness on the surface of the photovoltaic panel 1 caused by water mist spraying at night, while saving water resources and energy consumption; In order to improve the mechanical dynamic bird deterrence effect of the linear actuator 301, a human-shaped board can be installed at the output end of the linear actuator 301 to increase the shadow area.

[0036] This system also includes a power supply system, which is electrically connected to the lifting-type water mist bird deterrent device 3, the water supply and filtration system, the photovoltaic panel cleaner, and the intelligent control system, providing suitable power for all electrical equipment. In this embodiment, the power supply system is preferentially connected to the self-use power circuit of the fishery-solar complementary photovoltaic power station to achieve energy self-sufficiency and reduce operating costs; at the same time, a lithium battery energy storage device is equipped as a backup power source to ensure the stable operation of the system under conditions such as continuous rainy days and nighttime.

[0037] In this embodiment, the photovoltaic array is rotatably mounted on the top of the photovoltaic support frame via a bottom support frame. The top of the photovoltaic support frame is provided with a mounting base, and the end of the bottom support frame is mounted on the mounting base via bearings. An electric push rod is hinged between one side of the photovoltaic support frame and the bottom support frame. The two ends of the electric push rod are respectively hinged to the photovoltaic support frame and the bottom support frame. The electric push rod is electrically connected to the intelligent control system. By controlling the extension and retraction of the electric push rod, the angle adjustment and swing of the photovoltaic array can be realized. On the one hand, it can adapt to the angle of illumination, and on the other hand, the swing of the photovoltaic array can create a bird-repelling effect.

[0038] The specific working process of the system provided in this embodiment is as follows: Standby state: The system is in low power standby mode, the water supply filtration system is in a shutdown standby state, the linear driver 301 of the lifting water mist bird repellent device 3 retracts to the initial position, and the photovoltaic panel cleaner is parked at the edge of the photovoltaic panel 1 array.

[0039] Bird deterrence operation triggered: When the visual sensor detects a bird landing on photovoltaic panel 1, it first controls the water intake pump of the water supply and filtration system to start, draws water from the fishpond, filters it through multi-stage filter 6, and then delivers high-pressure water to the main water supply pipeline.

[0040] Bird repelling by lifting spray: The main controller controls the linear actuator 301 of the lifting water mist bird repelling device 3 to rise at a constant speed through the lifting drive module. At the same time, the corresponding solenoid valve is opened through the nozzle 302 control module. The nozzle 302 continuously sprays water mist during the rising process. After the linear actuator 301 reaches the highest point, it stays for 3 seconds and then descends at a constant speed, continuously spraying water mist during the descent until the linear actuator 301 is completely retracted to the initial position. Then the solenoid valve is closed, completing one bird repelling operation cycle. Two operation cycles can be repeated according to the bird damage situation on site. Multiple sets of lifting water mist bird repelling devices 3 can also be controlled to patrol and operate in turn to achieve no dead angle coverage of the entire photovoltaic array.

[0041] Cleaning linkage operation: After all bird deterrence operations are completed, the main controller sends a start cleaning command to the photovoltaic panel cleaner through the communication module. After receiving the command, the photovoltaic panel cleaner starts from the charging position and moves along the linear guide rail 12 on the surface of the photovoltaic panel 1. The front cleaning roller brush 10 rotates to clean the bird droppings and dust on the surface of the photovoltaic panel 1, while the rear drying module wipes away the water mist and droplets remaining on the panel surface. After cleaning a single photovoltaic panel 1, it switches to the adjacent photovoltaic panel 1 along the preset path to continue the operation.

[0042] Standby Reset: After the photovoltaic panel cleaner completes all cleaning operations, it automatically returns to the charging position and sends a signal of completion to the main controller via the wireless communication module. The main controller then stops the water pump of the water supply filtration system, and the system returns to standby mode, waiting for the next timed trigger.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
