Description

Technical Field

[0001] The present invention belongs to the field of maintenance of new energy equipment. Specifically, it relates to a solar photovoltaic panel maintenance system utilizing wave energy. Background Art

[0002] Due to the continuous growth of global energy demand and the imminent environmental protection, the development and utilization of renewable energy have become the focus of attention of various countries. Driven by the policies of carbon peak and carbon neutrality, offshore photovoltaic power generation has gradually become a research hotspot in the international energy field. As a new form of renewable energy and clean energy, offshore photovoltaic power generation helps to improve the energy self-sufficiency rate, reduce the dependence on fossil fuels, lower carbon emissions, promote the innovation and development of new energy technologies, and provide technical support for future energy transformation.

[0003] However, offshore photovoltaic power generation also faces severe challenges. The efficiency of photovoltaic power generation is relatively low, usually below 20%, and is restricted by many conditions. Under rainless conditions, particulate matters such as haze and dust in the air will form a layer of dust on the surface of photovoltaic modules, affecting the light transmittance of the photovoltaic modules, thereby reducing the power generation performance of the photovoltaic modules. At the same time, the covering of dust makes the heat dissipation condition of the photovoltaic modules worse, and the surface temperature of the photovoltaic panels is too high, which will also affect the efficiency of photovoltaic power generation. In the marine environment, factors such as salt spray corrosion, seawater sputtering, and the attachment of algae and shellfish organisms also seriously affect the normal operation of the photovoltaic power generation system, and due to the long distance from the land, the maintenance cost increases significantly. Therefore, it is very necessary to clean and cool the photovoltaic panels.

[0004] For the cooling of photovoltaic panels, the existing technologies can be divided into natural cooling and active cooling. Natural cooling uses natural wind for cooling, but in the offshore environment, the direction and speed of the wind change greatly, increasing the cooling difficulty. Active cooling includes liquid cooling, heat pipe cooling, and phase change material cooling. Liquid cooling transfers heat to a circulating liquid (such as water, ethylene glycol, etc.), and heat pipe cooling uses the high heat transfer performance of heat pipes to quickly transfer the heat generated by the photovoltaic panels to the cooling medium. However, the pipeline designs of both are relatively complex, and the problem of seawater corrosion needs to be solved; phase change material cooling uses the characteristic that a large amount of heat is absorbed during the phase change of the phase change material for cooling. This method can achieve efficient cooling without consuming additional energy, but the stability and reuse of the phase change material need to be solved.

[0005] For the cleaning of photovoltaic panels, the existing methods include mechanical dust removal, automated cleaning technology, and self-cleaning technology. Traditional mechanical dust removal methods include manual cleaning and high-pressure water gun cleaning. However, for offshore photovoltaic panels, due to their remoteness from land, large area, and harsh environment, these methods are difficult to operate and costly. Automated cleaning technology uses equipment such as robots and drones for cleaning. These technologies can significantly improve cleaning efficiency and reduce labor costs, but their design is relatively complex and the cost increases accordingly. Self-cleaning technology is a technology that enables dust and other pollutants to naturally fall off under the action of rain or wind through special coatings or structural designs on the surface of photovoltaic panels. This technology can reduce the number of cleaning times and costs, but for offshore photovoltaic panels, due to less rain and strong wind, the self-cleaning effect may be affected to a certain extent.

[0006] Therefore, by choosing wave energy, which has a large energy flux density, is widely distributed, and belongs to renewable energy, a fully automated and fully mechanized offshore photovoltaic power generation device is designed to achieve self-cooling and cleaning of photovoltaic panels, and improve the operation efficiency and reliability of offshore photovoltaic power generation. Summary of the Invention

[0007] The present invention provides a solar photovoltaic panel maintenance system using wave energy. In a way of saving bit by bit and withdrawing in a lump sum, when the sea wave acts, seawater is stored in a high-level water tank at a high place. The seawater is released at a certain flow rate, and a cleaning mechanism on the photovoltaic panel is pulled by a mechanical structure to complete the cleaning and cooling of the solar photovoltaic panel.

[0008] A solar photovoltaic panel maintenance system using wave energy includes a piston-type liquid level lifting system, a seawater storage and desalination system, and a photovoltaic panel cleaning system.

[0009] The piston-type liquid level lifting system includes a main housing, an elastic hemispherical mechanism, a water pressure piston, and a liquid level lifting conduit. The main housing is hermetically connected to the hemispherical mechanism. The water pressure piston is fixed at the center of the elastic hemispherical mechanism. A piston channel for the water pressure piston to slide is provided on the main housing. The left end of the piston channel is communicated with the inside of the hemispherical mechanism, and the right end of the piston channel is communicated with the liquid level lifting conduit. The end of the liquid level lifting conduit conveys seawater to the seawater storage and desalination system; two openings are provided in the upper part of the hemispherical mechanism; the seawater storage and desalination system is used for desalinating the seawater supplied by the piston-type liquid level lifting system and conveying the desalinated seawater to the photovoltaic panel cleaning system for cleaning the solar photovoltaic panel; the photovoltaic panel cleaning system includes a liquid receiving part and a cleaning part. The liquid receiving part is used for storing the seawater discharged from the seawater storage and desalination system and intermittently pouring the stored seawater; the cleaning part is arranged on the solar photovoltaic panel and is used for cleaning the surface of the solar photovoltaic panel according to the kinetic energy generated when the liquid receiving part pours seawater.

[0010] Among them, the cleaning part mainly consists of a U-shaped clamp, a fixed pulley, a connecting plate, a scrubbing cotton cloth, a fixing steel plate, a return spring and a water guide clamp. The U-shaped clamp is arranged on both sides of the solar photovoltaic panel. Rollers are installed on the U-shaped clamp to facilitate reciprocating movement on the surface of the solar photovoltaic panel. The U-shaped clamp is connected to the connecting plate, and the scrubbing cotton cloth is fixed to the connecting plate. Fixed pulleys are respectively fixed on the wall surface of the liquid receiving water tank and the lower end of the solar photovoltaic panel. One end of the pulley wire is connected to the liquid receiving hopper, and the other end is connected to the connecting plate after passing through the fixed pulley. A fixing steel plate is installed at the upper end of the solar photovoltaic panel. One end of the return spring is connected to the fixing steel plate, and the other end is connected to the connecting plate.

[0011] Among them, the liquid receiving part mainly consists of a liquid receiving water tank, a liquid receiving hopper and a fixed hinge support. The fixed hinge support is fixed at the bottom of the liquid receiving water tank, and the liquid receiving hopper is hinged to the fixed hinge support.

[0012] Among them, reset baffles are arranged on both the left side and the lower side of the liquid receiving hopper. In the waterless state, the liquid receiving hopper is close to the reset baffle. As the liquid level in the liquid receiving hopper rises, the center of gravity of the liquid receiving hopper gradually moves to the right. When the center of gravity of the liquid receiving hopper crosses the vertical plane where the axis of the fixed hinge support is located, the liquid receiving hopper flips and drives the cleaning part to move.

[0013] Among them, the seawater storage and desalination system includes a box body, a Fresnel lens, a distillation box cover, a water collecting tank and a distillation water tank. The distillation box cover is a frustum-shaped distilled water diversion surface. The Fresnel lens is fixed on the top of the distillation box cover. The water collecting tank is arranged inside the distillation box cover in an annular layout. The bottom of the water collecting tank is inclined. A liquid guide pipe is arranged on the side of the water collecting tank, and a second water outlet valve is arranged on the liquid guide pipe. A siphon and a black hydrogel are arranged inside the box body. The Fresnel lens focuses the light onto the hydrogel area. The water outlet of the siphon extends below the box body, and a first water outlet valve is arranged at the bottom of the box body.

[0014] Among them, the liquid level lifting conduit is a thin flat pipe, and the water outlet of the liquid level lifting conduit extends to the outside of the distillation box cover.

[0015] Among them, the first water outlet valve of the box body and the second water outlet valve of the distillation water tank are both opened to a certain degree, so that seawater can continuously enter the liquid receiving hopper of the liquid receiving water tank at a certain flow rate, and the water in the distillation water tank continuously and evenly flows to the photovoltaic panel at a certain flow rate.

[0016] Among them, a floating block is arranged below the main housing. The floating block is adhered to the main housing, and the floating block is connected to four pillars fixed to the seabed through a sleeve.

[0017] Compared with the prior art, the beneficial effects of the technical solution of the present invention are:

[0018] First, efficient conversion and stabilization of wave energy: A piston-type liquid level lifting system is designed. Under the action of ocean waves, the hemispherical mechanism squeezes the seawater in the cavity into the high-level water tank. Using the high-level water tank as a buffer link, the time-varying and irregular wave energy is converted into stable potential energy, eliminating the intermittency and randomness of wave energy and realizing the efficient and stable utilization of wave energy.

[0019] Second, the non-electric cleaning mechanism: Through the ingenious design of the liquid receiving water tank and the liquid receiving hopper, the potential energy of the water in the high-level water tank is converted into the mechanical movement of the cleaning structure, thus realizing the non-electric cleaning of the solar photovoltaic panel. This mechanism is simple and reliable, with low cost, effectively reducing the energy consumption during the cleaning process.

[0020] Third, solar-driven seawater distillation: The present invention uses a Fresnel lens to focus sunlight and distill the seawater in the high-level water tank. This process makes full use of solar energy, is energy-saving and environmentally friendly, and the obtained distilled water can be stored for the cleaning and cooling of solar photovoltaic panels, further enhancing the self-sufficiency ability of the system.

[0021] Fourth, precise water flow control and timed cleaning function: The system is provided with two outlet valves with fixed openings. By precisely controlling the water flow, not only can electricity be saved, but also the effect of timed cleaning of the solar photovoltaic panel can be achieved, further optimizing the cleaning efficiency and resource utilization.

[0027] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but the scope of protection required by the present invention is not limited thereto.

[0028] As Figures 1 to 4 shown, a solar photovoltaic panel maintenance system using wave energy includes a piston-type liquid level lifting system, a seawater storage and desalination system, and a photovoltaic panel cleaning system.

[0029] The piston-type liquid level lifting system includes a main housing 4, an elastic hemispherical mechanism 1, a water pressure piston 3, and a liquid level lifting conduit 5. The main housing 4 is hermetically connected to the hemispherical mechanism 1. The water pressure piston 3 is fixed at the center of the elastic hemispherical mechanism 1. A piston passage for the water pressure piston 3 to slide is provided on the main housing 4. The left end of the piston passage communicates with the inside of the hemispherical mechanism 1, and the right end of the piston passage communicates with the liquid level lifting conduit 5. The end of the liquid level lifting conduit 5 conveys seawater to the seawater storage and desalination system; two openings 30 are provided in the upper part of the hemispherical mechanism 1 to allow seawater to flow into the piston-type liquid level lifting system therefrom; the seawater storage and desalination system is used to desalinate the seawater supplied by the piston-type liquid level lifting system and convey the desalinated seawater to the photovoltaic panel cleaning system for cleaning the solar photovoltaic panel 22; the photovoltaic panel cleaning system includes a liquid receiving part and a cleaning part. The liquid receiving part is used to store the seawater discharged from the seawater storage and desalination system and intermittently pour the stored seawater; the cleaning part is arranged on the solar photovoltaic panel 22 and is used to clean the surface of the solar photovoltaic panel 22 according to the kinetic energy generated when the liquid receiving part pours seawater.

[0030] Among them, the cleaning part is mainly composed of a U-shaped clamp 23, a fixed pulley 19, a connecting plate 27, a scrubbing cotton cloth 28, a fixed steel plate 25, a return spring 24, and a water guiding clamp 26. The U-shaped clamp 23 is arranged on both sides of the solar photovoltaic panel 22. Rollers are installed on the U-shaped clamp 23 to facilitate reciprocating movement on the surface of the solar photovoltaic panel 22. The U-shaped clamp 23 is connected to the connecting plate 27. The scrubbing cotton cloth 28 is fixed on the connecting plate 27. Fixed pulleys 19 are respectively fixed on the wall surface of the liquid receiving water tank 18 and the lower end of the solar photovoltaic panel 22. One end of the pulley wire is connected to the liquid receiving hopper 16, and the other end passes through the fixed pulley 19 and is connected to the connecting plate 27; a fixed steel plate 25 is installed at the upper end of the solar photovoltaic panel 22. One end of the return spring 24 is connected to the fixed steel plate 25, and the other end is connected to the connecting plate 27.

[0031] Among them, the liquid receiving part is mainly composed of a liquid receiving water tank 18, a liquid receiving hopper 16, and a fixed hinge support 17. The fixed hinge support 17 is fixed at the bottom of the liquid receiving water tank 18. The liquid receiving hopper 16 is hinged to the fixed hinge support 17.

[0032] Among them, reset baffles 29 are provided on both the left side and the lower side of the liquid receiving hopper 16. In the waterless state, the liquid receiving hopper 16 closely adheres to the reset baffle 29. As the liquid level in the liquid receiving hopper 16 rises, the center of gravity of the liquid receiving hopper 16 gradually moves to the right. When the center of gravity of the liquid receiving hopper 16 crosses the vertical plane where the axis of the fixed hinge support 17 is located, the liquid receiving hopper 16 flips and drives the cleaning part to move.

[0033] Among them, the seawater storage and desalination system includes a box body 7, a Fresnel lens 10, a distillation box cover 11, a water collection tank 12, and a distillation water tank 14. The distillation box cover 11 is a frustum-shaped distilled water diversion surface. The Fresnel lens 10 is fixed on the top of the distillation box cover 11. The water collection tank 12 is arranged in a ring shape inside the distillation box cover 11. The bottom of the water collection tank 12 is inclined so that the distilled water can quickly flow to the distilled water outlet under the action of gravity. A liquid guide pipe 13 is provided on the side of the water collection tank 12, and a second water outlet valve 20 is provided on the liquid guide pipe 13. A siphon 8 and a black hydrogel 9 are arranged inside the box body 7. After the sun rays are refracted multiple times by the serrated Fresnel lens 10, they are focused on the area of the internal black hydrogel 9, improving the concentration of heat, enabling the seawater to quickly evaporate on its surface. The water outlet of the siphon 8 extends below the box body 7 to control the height of the seawater liquid level. A first water outlet valve 15 is provided at the bottom of the box body 7, and the outside of the box body 7 is wrapped with heat insulation materials to reduce heat loss.

[0034] Among them, the liquid level lifting conduit 5 uses a thin flat pipe, which can significantly reduce the working pressure required to lift the seawater, establish a continuous water column, and facilitate the lifting of the seawater liquid level. The water outlet of the liquid level lifting conduit 5 extends to the outside of the distillation box cover 11, enabling the lifted seawater to flow through the outside of the distillation box cover 11 for cooling, and then flowing into the high-level water tank 7.

[0035] Among them, the first water outlet valve 15 of the box body 7 and the second water outlet valve 20 of the distillation water tank 11 are both opened to a certain degree, enabling the seawater to continuously enter the liquid receiving hopper 16 of the liquid receiving water tank 18 at a certain flow rate, and the water in the distillation water tank 14 continuously and evenly flows to the photovoltaic panel at a certain flow rate.

[0036] Among them, a floating block 2 is provided below the main housing 4. The floating block 2 is adhered to the main housing 4. The floating block 2 is connected to four struts 6 fixed to the seabed through a sleeve, enabling the piston-type liquid level lifting system to only float up and down, and its height can be adjusted with the sea level liquid level, so that the sea level is always at about 3 / 4 of the height of the elastic hemispherical mechanism (1).

[0037] The working process of the solar photovoltaic panel maintenance system of the present invention is as follows:

[0038] When there is no wave action, the sea water inside and outside the system is connected, and the sea water can enter the main housing 4 through the opening 30 on the elastic hemispherical mechanism 1. When wave action occurs, the elastic hemispherical mechanism 1 deforms, pushing the water pressure piston 3 to move inward. At the same time, the water pressure piston 3 separates the sea water inside and outside the system. The sea water inside the system is lifted along the liquid level lifting conduit 5 under the pressure of the elastic hemispherical mechanism 1 and the water pressure piston 3, and the sea water is pressed into the high-level water tank 7. The sea water in the high-level water tank 7 evaporates under the action of the Fresnel lens 10. The water vapor condenses on the distillation box cover 11 and flows along the wall surface into the water collection tank 12, and is introduced into the distillation water tank 14 by the liquid guide pipe 13; at the water outlet at the lower part of the high-level water tank 7, the opening degree of the water outlet valve 15 is fixed, and the sea water enters the liquid receiving hopper 16 of the liquid receiving water tank 18 at a certain flow rate to drive the movement of the photovoltaic panel cleaning device; the water in the distillation water tank 14 also uniformly flows onto the photovoltaic panel 22 at a certain speed under the action of the water outlet valve 20 with a fixed opening degree to moisten the photovoltaic panel 22; the change in the water volume in the liquid receiving hopper 16 causes it to flip regularly. During the process of the liquid receiving hopper 16 flipping and pouring out the sea water, the cleaning device is driven to scrub the photovoltaic panel 22 from top to bottom once. At this time, the return spring 24 is stretched to the longest state. After the sea water in the liquid receiving hopper 16 is emptied, the weight decreases, and under the action of the return spring 24, the cleaning device is pulled back to the top of the photovoltaic panel 22, and then the liquid receiving hopper 16 at the other end of the fixed pulley returns to its original position. The repeated movement of the photovoltaic panel cleaning device and the liquid receiving hopper realizes the cleaning and cooling of the solar photovoltaic panel 22.

[0039] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or variations derived from the spirit of the present invention are still within the protection scope of the present invention.
