Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a photovoltaic panel cleaning structure for a power plant. Background Art

[0002] Photovoltaic panels in power plants, also known as solar panels, are the core components of photovoltaic power generation systems. They are flat-plate devices made of multiple solar cell units (also known as photovoltaic cells) connected in series and parallel. These photovoltaic cells are usually made of silicon-based materials and use the photoelectric effect to convert solar energy into DC electricity. Their main function is to directly convert solar radiation energy into electrical energy for use in power plants or to be incorporated into the power grid. They are usually installed in large photovoltaic power stations to generate enough electricity to meet electricity demand. Photovoltaic panels can be installed on various ground surfaces, such as deserts, mountains, roofs, etc. As long as there is enough sunlight, power generation can be achieved. During the use of existing solar photovoltaic modules, impurities and garbage on the surface of the photovoltaic modules will accumulate on the surface of the solar photovoltaic panels if they are not cleaned for a long time, affecting the energy absorption and power generation effect of the solar photovoltaic modules.

[0004] Regarding the above-mentioned related schemes, the photovoltaic panel is cleaned by the cooperation of the rotating disk, the first connecting rod, the first connecting frame, the first brush roller, the second connecting rod, the second connecting frame and the second brush roller. However, since the area occupied on the photovoltaic panel is large, it will affect the photovoltaic panel's absorption of solar energy, which is not conducive to power generation. In addition, the photovoltaic panel is dry-brushed only by the first brush roller and the second brush roller, which makes it difficult to quickly clean the photovoltaic panel, and the cleaning effect is poor and the cleaning efficiency is low.

In this process, the second through hole and the first through hole are repeatedly conducted and blocked, so that the discharged water flow can flush the cleaned main body of the photovoltaic panel, thereby further improving the cleaning effect on the main body of the photovoltaic panel, improving the cleaning efficiency at the same time, and the setting of this structure will not affect the absorption of solar energy by the main body of the photovoltaic panel.

[0021] The embodiments of the present utility model will be described below according to the overall structure of the present utility model.

[0022] A cleaning structure for a power plant photovoltaic panel, as Figure 1 , Figure 2 ,Figure 3 and Figure 4 As shown in Figure 4 , it includes a photovoltaic panel main body 1, and a cleaning mechanism 2 is arranged on the outer side of the photovoltaic panel main body 1. The cleaning mechanism 2 includes side plates 201, threaded blocks 203, support plates 204 and a driving motor 206. The side plates 201 are symmetrically welded on both sides of the photovoltaic panel main body 1. A lead screw 202 is rotatably connected to the inner sides of a group of the side plates 201 through bearings. A threaded block 203 is threadedly connected to the outer side of the lead screw 202. A cleaning brush 205 is arranged above the side plates 201. A driving motor 206 connected to the lead screw 202 through a coupling is installed at one end of a group of the side plates 201. Support plates 204 are welded to the tops of the guide blocks 6 and the threaded blocks 203;

[0023] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be known that when the driving motor 206 works, the output end of the driving motor 206 drives the lead screw 202 to rotate. Since the lead screw 202 is threadedly connected to the threaded block 203, the threaded block 203 and the cleaning brush 205 can slide along the photovoltaic panel main body 1, so that the cleaning operation of the photovoltaic panel main body 1 can be realized through the cleaning brush 205.

[0024] Refer to Figure 1 It can be known that a guide rod 5 is welded to the inner sides of the other group of side plates 201. A guide block 6 is slidably connected to the outer side of the guide rod 5, which can play a role in supporting and limiting, so as to prevent the threaded block 203 from shifting.

[0025] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be known that a flushing mechanism 4 is arranged between the two support plates 204. The flushing mechanism 4 is composed of a water storage frame 401, a notch 402, a first through hole 403 and a second through hole 404. The water storage frame 401 is welded between the two support plates 204. A notch 402 is opened at the top of the water storage frame 401, and a filter screen is arranged at the top of the notch 402. A first through hole 403 is opened at equal intervals at the bottom of the water storage frame 401. Second through holes 404 are opened at equal intervals inside the cleaning brush 205;

[0026] Refer to Figure 1 , Figure 2 and Figure 4 It can be known that the second through holes 404 and the first through holes 403 are reciprocally conducted and blocked, so that the discharged water flow can flush the cleaned photovoltaic panel main body 1, thereby further improving the cleaning effect on the photovoltaic panel main body 1.

[0027] Refer to Figure 4It can be seen that limit plates 8 are symmetrically welded to the top of the cleaning brush 205, and limit grooves 7 are formed on both sides of the water storage frame 401. The cleaning brush 205 and the water storage frame 401 form a sliding structure through the limit grooves 7 and the limit plates 8, which can play a role in supporting and limiting, so as to increase the stability of the cleaning brush 205 during the sliding process and prevent the cleaning brush 205 from shifting.

[0028] Refer to Figure 1 、 Figure 2 and Figure 3 It can be seen that at the top of the threaded block 203, an active mechanism 3 connected to the cleaning brush 205 is arranged inside the support plate 204. The active mechanism 3 is composed of a mounting frame 301, a rotary motor 302, a rotary plate 303 and a linkage plate 304. The mounting frame 301 is welded to the top of the threaded block 203. The rotary motor 302 is installed at the top inside the mounting frame 301. The output end of the rotary motor 302 is connected to a rotary plate 303, and a linkage plate 304 is rotatably connected between the rotary plate 303 and the cleaning brush 205;

[0029] Refer to Figure 1 and Figure 2 It can be seen that since the cleaning brush 205 is connected to the rotary plate 303 through the linkage plate 304, the cleaning brush 205 makes a reciprocating movement in the left and right directions, thereby increasing the friction between the cleaning brush 205 and the main body 1 of the photovoltaic panel, and further improving the cleaning effect on the main body 1 of the photovoltaic panel.

[0030] The working principle of the present utility model is as follows: When using the cleaning structure for the photovoltaic panel of the power plant, start the driving motor 206, so that the output end of the driving motor 206 drives the lead screw 202 to rotate, and then the threaded block 203 and the cleaning brush 205 can slide along the main body 1 of the photovoltaic panel, so that the cleaning operation of the main body 1 of the photovoltaic panel can be realized through the cleaning brush 205. At the same time, start the rotary motor 302, and the output end of the rotary motor 302 drives the rotary plate 303 to rotate, so that the cleaning brush 205 makes a reciprocating movement in the left and right directions under the cooperation of the rotary plate 303 and the linkage plate 304, thereby increasing the friction between the cleaning brush 205 and the main body 1 of the photovoltaic panel, and further improving the cleaning effect on the main body 1 of the photovoltaic panel. During this process, the second through hole 404 and the first through hole 403 are reciprocally conducted and blocked, so that the discharged water flow can wash the cleaned main body 1 of the photovoltaic panel, thereby further improving the cleaning effect on the main body 1 of the photovoltaic panel and improving the cleaning efficiency at the same time.
