Description

TECHNICAL FIELD

[0001] The utility model belongs to solar cell panel structure technical field especially relates to a device that can automatic cooling and cleaning solar cell panel. BACKGROUND

[0002] Atmospheric dust is one of the key factors affecting the efficiency of solar power generation, and dust pollution can significantly reduce the power generation of photovoltaic power stations. According to research, it is estimated that it will be reduced by at least 5% per year. There are three reasons why dust can have such a big impact: temperature effect, shading effect, and corrosion effect. Dust adhering to the surface of the panel will block, absorb and reflect light, of which the most important is the blocking effect of light. Dust particles reflect, absorb and block light, affecting the absorption of photovoltaic panels, thereby affecting the efficiency of photovoltaic power generation. With the accumulation of dust on the surface of the assembly, the thermal resistance of the photovoltaic assembly is increased, becoming a thermal insulation layer on the photovoltaic assembly, affecting its heat dissipation. And the covered part of the battery assembly under long-term sunlight is heated at a much faster rate than the uncovered part, causing the temperature to be too high and the dark spots to be burned out. The surface of the photovoltaic panel is mostly made of glass, and the main components of glass are silicon dioxide and limestone. When wet acidic or alkaline dust adheres to the surface of the glass cover plate, the glass cover plate components can react with acid or base. With the increase of time in the acidic or alkaline environment, the surface of the glass will be slowly eroded, forming a pitted phenomenon on the surface, causing the light to form a diffuse reflection on the cover plate surface, and the uniformity of light propagation in the glass is destroyed. The rougher the photovoltaic assembly cover, the smaller the refracted light energy, the actual energy reaching the photovoltaic cell surface is reduced, resulting in a decrease in the power generation of the photovoltaic cell. And the sticky surface with adhesive residues is more likely to accumulate dust than the smoother surface. Moreover, dust itself can also attract dust. Once there is initial dust, more dust will accumulate, accelerating the decay of photovoltaic cell power generation.

[0003] In order to solve the influence of atmospheric dust on solar cell panel, the current common scheme can be divided into three categories: manual cleaning, semi-automatic cleaning and automatic cleaning. Manual cleaning is divided into dry cleaning and water cleaning, but manual cleaning has low work efficiency, long cleaning cycle, high labor cost and personal safety risks. Semi-automatic cleaning is mostly similar to a water truck. This design is more suitable for small and medium-sized power stations and is not suitable for small photovoltaic panels installed at home. Automatic cleaning is basically a robot sweeper mode used for large power stations. The design of full-automatic cleaning of solar cell panels installed at home mostly uses a roller to sweep back and forth, which is a single design mode and function. UTILITY MODEL CONTENT

[0016] When the sensor detects that the surface temperature of the solar panel is higher than the preset value, it sends an electrical signal to the controller. After receiving the high temperature electrical signal, the controller controls the water spray component to draw water from the water storage component and spray it onto the solar panel.

[0038] According to the dust cleaning time and frequency, the controller controls the cleaning component to start, moves back and forth on the solar cell panel 1 through the slide rail 6, and cleans the surface of the solar cell panel 1, and the water spraying component is used in cooperation to clean the dust on the surface of the solar cell panel 1 more thoroughly;

[0039] When the sensor 3 detects that it is raining and the water level in the water storage component 11 is low, the rainwater collecting component is controlled to rotate from the parallel state with the solar cell panel 1 to the perpendicular state with the solar cell panel 1, the rainwater sliding down from the solar cell panel 1 is blocked by the rainwater collecting component and flows into the water storage component 11 from both ends of the connection between them;

[0046] The rainwater collecting component includes a rainwater collecting plate 9, which is rotatably connected with the lower end of the frame 2 through a plate control component 8, and two collecting pipelines 10 are arranged at the rotatable connection position, one end of each of the two collecting pipelines 10 is fixed on the two sides of the frame 2, and the other end of each of the two collecting pipelines 10 is connected with the two ends of the water storage component 11;

[0047] A safety water level line 13 and a warning line 14 are arranged on the inner side wall of the water storage component 11;

[0048] The lower end of the water storage component 11 is connected with a household water tank through a connecting water pipe 15, and a water pump is arranged at the connection position of the water storage component 11 and the connecting water pipe 15;

[0049] The cleaning component includes two sliding blocks 16, which are slidably connected with the two slide rails 6 through two groups of rollers 17, a support frame 23 is fixed between the two sliding blocks 16, a plurality of cleaning brush heads 22 are rotatably connected in the support frame 23, a motor 18 is arranged in the sliding block 16, a bevel gear 19 is arranged at the output end of the motor 18, the bevel gear 19 is in meshing transmission with a gear rod 20, the lower end of the gear rod 20 is in meshing transmission with the slide rail 6, and the upper end of the gear rod 20 is in transmission connection with the cleaning brush head 22 and between adjacent two cleaning brush heads 22 through a belt 21;

[0050] The plate control component 8 includes a pneumatic cylinder 24, which is fixed on the side surface of the frame 2, the output end of the pneumatic cylinder 24 is connected with a rack 25, and the rack 25 is in meshing transmission with a gear 26 fixed on the side surface of the rainwater collecting plate 9;

[0051] The working principle of the above technical scheme: the water pump connected with the water supply pipeline 5, the water pump connected with the connecting water pipe 15, the water storage component 11, the motor 18 and the air cylinder 24 are all electrically connected with the temperature sensor, the water pump connected with the water supply pipeline 5, the water pump connected with the connecting water pipe 15, the water storage component 11, the motor 18 and the air cylinder 24 are all electrically connected with the temperature sensor, and the temperature sensor and the rain and snow sensor are all electrically connected with the controller, and the temperature sensor and the rain and snow sensor are all electrically connected with the controller, and the water pump connected with the water supply pipeline 5, the water pump connected with the connecting water pipe 15, the water storage component 11, the motor 18, the air cylinder 24, the temperature sensor, the rain and snow sensor and the controller are all powered by the solar cell panel 1;

[0052] When the temperature sensor detects that the surface temperature of the solar cell panel 1 is higher than the preset value, an electrical signal is sent to the controller, and after the controller receives the high-temperature electrical signal, the water pump connected with the water supply pipeline 5 is started to draw water from the water storage component 11 through the water supply pipeline 5, and the water is sprayed to the surface of the solar cell panel 1 through the four water spraying heads 4 arranged at the four corners of the frame 2. The water spraying component will spray water according to the set time interval and water volume, and the sprayed water will evaporate, thereby taking away the heat around the solar cell panel 1 to achieve the effect of cooling. Compared with the traditional method of directly washing the battery panel with water, the damage to the battery panel is lower.

[0053] According to the dust cleaning time and frequency, the controller controls the motor 18 to start, drives the bevel gear 19 to rotate, drives the gear rod 20 to rotate, drives the cleaning component to slide on the slide rail 6 through the meshing transmission of the gear rod 20 and the slide rail 6, and the cleaning brush head 22 cleans the surface of the solar cell panel 1. At the same time, the gear rod 20 rotates to drive the cleaning brush head 22 through the belt 21, and the adjacent two cleaning brush heads 22 rotate through the belt 21, so that multiple cleaning brush heads 22 rotate while moving on the surface of the solar cell panel 1, and cooperate with the water spraying component to spray water to clean the dust on the surface of the solar cell panel 1 more thoroughly and better.

[0054] When the rain and snow sensor detects rain and the water level in the water storage component 11 is lower than the safe water level line 13, the controller controls the cylinder 24 to start, which drives the rack 25 to move forward, drives the gear 26 to rotate, and drives the rainwater collection plate 9 to rotate until it is perpendicular to the solar panel 1. The rainwater sliding down from the solar panel 1 is blocked by the rainwater collection plate 9, and the rainwater flows into the collection pipe 10 from both ends of the connection between the two, and then into the water storage component 11 through the collection pipe 10. When the water level in the water storage component 11 is higher than the safe water level line 13, the controller controls the cylinder 24 to start, which drives the rack 25 to move backward, drives the gear 26 to rotate, and drives the rainwater collection plate 9 to rotate until it is parallel to the solar panel 1. At this time, rainwater collection is no longer performed.

[0055] When the rain and snow sensor detects snowfall, the controller starts the motor 18, which drives the bevel gear 19 to rotate, which in turn drives the gear rod 20 to rotate. Through the meshing transmission between the gear rod 20 and the slide rail 6, the entire cleaning component slides on the slide rail 6. The cleaning brush head 22 cleans the surface of the solar panel 1. As the gear rod 20 rotates, it drives the cleaning brush head 22 through the belt 21. Two adjacent cleaning brush heads 22 will rotate through the belt 21. Thus, multiple cleaning brush heads 22 move on the surface of the solar panel 1 while rotating, pushing away the snow on the solar panel 1. This prevents the snow accumulation on the solar panel 1 from affecting power generation and also prevents the melting of the snow from damaging the solar panel 1.

[0056] Example 3

[0057] like Figures 1-9 As shown, both ends of the slide rail 6 are equipped with position sensors 7, and there is electromagnetic induction between the cleaning component and the position sensors 7.

[0058] The working principle of the above technical solution is as follows: The slider 16 is equipped with a sensor corresponding to the position sensor 7. When the slider 16 moves to the position, the slider 16 is controlled to move in the reversing direction, which facilitates the reciprocating motion of the slider 16, thereby enabling the cleaning brush head 22 to clean the surface of the solar panel 1 repeatedly, increasing the degree of cleaning.

[0059] Example 4

[0060] like Figures 1-9 As shown, filters 12 are provided at both ends of the connection between the two collection pipes 10 and the water storage component 11;

[0061] The working principle of the above technical solution: Filter 12 can filter impurities in rainwater.
