Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation panel technology, specifically a photovoltaic power generation panel with self-cleaning function. Background Technology

[0002] A photovoltaic (PV) panel (also known as a solar panel) is a device that converts sunlight into electrical energy and is widely used in solar power systems. Its working principle is based on the photoelectric effect: when sunlight shines on the surface of the PV panel, electrons in the photovoltaic material (such as silicon) are excited, thereby generating an electric current.

[0003] A self-cleaning photovoltaic panel, such as one disclosed in CN220586234U, includes a photovoltaic panel and a base. A backplate is fixedly installed on the back of the photovoltaic panel, and earrings are fixedly installed on both sides of the backplate away from the photovoltaic panel. A water tank is provided on one side of the base. A cleaning component is provided on the outer side of the photovoltaic panel, and a tilting component is provided on the top surface of the base. The tilting component can adjust the angle of the photovoltaic panel. The purpose of this photovoltaic panel is to solve the problem that most photovoltaic panel supports are usually fixed and cannot achieve high-efficiency power generation throughout the day. The achieved technical effect is that by adjusting the orientation of the photovoltaic panel through the tilting component, the photovoltaic panel can receive direct sunlight throughout the day to generate electricity, thereby achieving the highest power generation efficiency.

[0004] The aforementioned patent proposes that the water tank is connected to the spray nozzle through a pipe, which enables the spray nozzle to spray water onto the surface of the photovoltaic panel. The slider can slide along the slide rod by the rotation of the screw, so that the brush head provided on the bottom side of the slider can clean the surface of the photovoltaic panel. However, in actual use, if the water pressure of the sprayed water is not well controlled, it will damage the surface of the photovoltaic panel and affect the normal use of the photovoltaic panel. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic power generation panel with a self-cleaning function, so as to solve the problem mentioned in the background art that poor water pressure control of the sprayed water will damage the surface of the photovoltaic panel.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic power generation panel with self-cleaning function, comprising a photovoltaic structure, wherein the photovoltaic structure includes a supporting member, and a cleaning member is installed on one side of the supporting member;

[0007] The supporting component includes an inclined support frame, with an internal groove at the top of the inclined support frame. A partition strip is horizontally installed in the middle of the internal groove. An internal strip and a mounting plate are installed inside the internal groove and on both sides of the partition strip. Water inlet channels are provided at the top of the inclined support frame and the top of the mounting plate. Protective components are installed inside the water inlet channels. A photovoltaic panel is installed inside the inclined support frame. The top of the photovoltaic panel is provided with a superhydrophobic coating.

[0008] Preferably, a water inlet hole is provided through one side of the lower end of the water inlet trough, and the photovoltaic panel is installed inside the built-in trough.

[0009] Preferably, a drainage hole is installed in the middle of the inner groove, and bottom drainage holes are opened through the middle of the inner strip and the lower end of the inclined support frame, and a drainage hole is opened on one side of the inclined support frame.

[0010] Preferably, a water inlet pipe is installed on one side of the inclined support frame, and a side hole is opened through one side of the water inlet trough, with the water inlet pipe installed on one side of the side hole.

[0011] Preferably, the cleaning component includes legs, an inner plate is installed between the legs, a water tank is installed at the top of the legs, an inlet pipe is installed through the top of the water tank, a pipe plug is installed inside the inlet pipe, an inner top plate and a rubber frame are installed inside the water tank, the rubber frame is located on the outside of the inner top plate, and a cylinder is installed at the top of the inner plate.

[0012] Preferably, the protective component includes an inverted U-shaped frame and limiting plates installed on both sides of the bottom end of the inverted U-shaped frame, and bottom support pads are installed at the bottom ends of both the limiting plates and the inverted U-shaped frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The present invention discloses a photovoltaic power generation panel with self-cleaning function. The cleaning water enters the interior of the water inlet through the water inlet pipe and the water inlet channel. As the cleaning water accumulates inside the water inlet channel, when the cleaning water reaches the water inlet hole, the cleaning water will flow downward along the top of the superhydrophobic coating. The superhydrophobic coating can form a microstructure on the surface of the photovoltaic panel, so that the water droplets form a bead-like rolling effect on the surface. The water droplets carry away dust, dirt and other particles by rolling, keeping the surface clean and reducing manual operation.

[0015] 2. The photovoltaic power generation panel with self-cleaning function disclosed in this utility model has the following characteristics: the cleaning water inside the upper built-in groove is discharged into the space between the partition strip and the built-in strip through the bottom drain hole at the bottom end of the built-in strip, and the cleaning water is discharged through the drain hole. The cleaning water inside the lower built-in groove is discharged directly through the bottom drain hole at the bottom end of the inclined support frame to avoid liquid residue. After the cleaning water inside the water inlet groove is drained, the protective component moves down due to its own weight, and the limiting plate and bottom support pad block one side of the water inlet hole to prevent impurities in the environment where the photovoltaic structure is located from entering the water inlet groove.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-3 A photovoltaic power generation panel with self-cleaning function includes a photovoltaic structure 1, the photovoltaic structure 1 includes a support member 11, and a cleaning member 2 is installed on one side of the support member 11.

[0023] The supporting member 11 includes an inclined support frame 111. The top of the inclined support frame 111 has an internal groove 112. A partition strip 13 is horizontally installed in the middle of the internal groove 112. An internal strip 119 and a mounting plate 117 are respectively installed inside the internal groove 112 and on both sides of the partition strip 13. A water channel 113 is provided at the top of both the inclined support frame 111 and the top of the mounting plate 117. A protective member 14 is installed inside the water channel 113. A photovoltaic panel is installed inside the inclined support frame 111. The top of the photovoltaic panel is provided with a superhydrophobic coating 12. The superhydrophobic coating 12 keeps the surface of the photovoltaic panel clean, maximizes the light transmittance, and improves the power generation efficiency.

[0024] A water inlet hole 115 is provided through one side of the lower end of the water inlet trough 113. The photovoltaic panel is installed inside the built-in trough 112. The water inlet hole 115 is located inside the body of the inclined support frame 111 and the mounting plate 117.

[0025] A drain hole 118 is installed in the middle of the inner groove 112. Bottom drain holes 114 are opened through the middle of the inner strip 119 and the lower end of the inclined support frame 111. A drain hole 118 is opened on one side of the inclined support frame 111. The drain hole 118 is located between the inner strip 119 and the partition strip 13.

[0026] A water pipe 15 is installed on one side of the inclined support frame 111. A side hole 116 is opened through one side of the water channel 113. The water pipe 15 is installed on one side of the side hole 116. The side hole 116 and the water pipe 15 facilitate the entry of cleaning water inside the cleaning component 2 into the water channel 113.

[0027] The cleaning component 2 includes legs 21, an inner plate 22 installed between the legs 21, a water tank 23 installed at the top of the legs 21, an inlet pipe 24 installed through the top of the water tank 23, a pipe plug 25 installed inside the inlet pipe 24, an inner top plate 27 and a rubber frame 28 installed inside the water tank 23, the rubber frame 28 being located on the outside of the inner top plate 27, a cylinder 26 installed at the top of the inner plate 22, the moving end of the cylinder 26 penetrating through the bottom of the water tank 23, and the top of the cylinder 26 being installed at the bottom of the inner top plate 27.

[0028] In this embodiment: when cleaning the top of the photovoltaic panel installed inside the inclined support frame 111, the cylinder 26 extends to push the inner top plate 27 and rubber frame 28 of the water tank 23 upward, pushing the cleaning water to one side of the water inlet pipe 15. The cleaning water enters the interior of the water inlet 113 through the water inlet pipe 15 and the water inlet 113. As the cleaning water accumulates inside the water inlet 113, when the cleaning water reaches the water inlet hole 115, the cleaning water will flow downward along the top of the superhydrophobic coating 12. The superhydrophobic coating 12 can form a microstructure on the surface of the photovoltaic panel, so that the water droplets form a bead-like rolling effect on the surface. The water droplets carry away dust, dirt and other particles by rolling, keeping the surface clean and reducing manual operation.

[0029] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The protective component 14 includes an inverted U-shaped frame 141 and limiting plates 142 installed on both sides of the bottom end of the inverted U-shaped frame 141. The bottom end of both the limiting plate 142 and the bottom end of the inverted U-shaped frame 141 is equipped with a bottom support pad 143. The bottom support pad 143 is made of carbon fiber composite material, with carbon fiber as the reinforcement and resin as the matrix. It has extremely high strength, rigidity and lightweight characteristics, and can resist corrosion and high temperature.

[0030] In this embodiment: the cleaning water inside the upper built-in groove 112 is drained into the space between the partition strip 13 and the built-in strip 119 through the bottom drain hole 114 at the bottom end of the built-in strip 119, and then discharged through the drain hole 118. The cleaning water inside the lower built-in groove 112 is directly discharged through the bottom drain hole 114 at the bottom end of the inclined support frame 111 to avoid liquid residue. After the cleaning water inside the water inlet trough 113 is drained, the protective member 14 moves down due to its own weight, using the limiting plate. 142 and the bottom support pad 143 block one side of the water inlet hole 115 to prevent impurities in the environment where the photovoltaic structure 1 is located from entering the water inlet tank 113. When cleaning the photovoltaic panel, when the cleaning water accumulates inside the water inlet tank 113, the inverted U-shaped frame 141 and the limiting plate 142 move upward due to the buoyancy of the bottom support pad 143. When the top of the cleaning water is at the bottom of the water inlet hole 115, the cleaning water can flow out, reducing the impact force of the cleaning water flowing towards the photovoltaic panel and protecting the photovoltaic panel.
