Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a snow removal device on the surface of a photovoltaic panel. Background Art

[0002] Photovoltaic modules are composed of solar cells or solar cells of different specifications cut by laser cutting machines or wire cutting machines. Since the current and voltage of a single solar cell are very small, we connect them in series to obtain high voltage, and then in parallel to obtain high current, and then output them through a diode. We also package them in a stainless steel, aluminum or other non-metallic frame, install the glass on the top and the back panel on the back, fill them with nitrogen, and seal them. The whole is called a module, which is a photovoltaic module or a solar cell module.

[0003] The existing photovoltaic modules cannot be operated for a period of time after snow accumulates on the surface. At present, the snow is generally cleared by air flow or roller brushes, but such methods can only clear most of the snow, and there will still be some residue. The cleaning effect is not good, which is not conducive to the normal operation of the photovoltaic modules. Therefore, we propose a snow removal device for the surface of photovoltaic panels.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] A photovoltaic panel surface snow removal device provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0023] Combination Figure 1-3 As shown, the utility model provides a photovoltaic panel surface snow removal device, comprising: a photovoltaic component 100 and a snow removal component 200; wherein the photovoltaic component 100 comprises a mounting frame 110 and a solar cell panel 120 mounted on the mounting frame 110.

[0024] The snow removal assembly 200 is arranged on the solar panel 120, and the snow removal assembly 200 includes a storage box 210 installed on the top of the solar panel 120, a winding roller 220 installed in the storage box 210, a servo motor 230 fixed to one end of the winding roller 220, a traction rope 240 wound around the winding roller 220, a roller frame 250 connected to the end of the traction rope 240, a fixed roller 260 installed on the inner side of the roller frame 250, a water storage cylinder 270 arranged on the outer side of the fixed roller 260, a heating rod 280 installed in the water storage cylinder 270, and a heating rod 280 arranged in the water storage cylinder 270. The silicone sleeve 290 on the outside of the water storage cylinder 270 can use the servo motor 230 to drive the winding roller 220 to rotate and loosen the traction rope 240 through the snow removal component 200, so that the fixed roller 260 rolls out of the storage box 210 and falls on the solar panel 120. At the same time, the heat generated by the heating rod 280 diffuses outward to melt the snow on the solar panel 120, so that the fixed roller 260 rolls toward the bottom along the surface of the solar panel 120. This method can melt all the snow on the solar panel 120, and the cleaning effect is better. It will not cause damage to the solar panel 120 and has high practicality.

[0025] Furthermore, a controller 211 is installed at the bottom of the storage box 210, which can control the operation of the servo motor 230, the electric push rod 253 and the heating rod 280, so as to facilitate automated operation.

[0026] On the other hand, a switch door 212 is provided on the side of the storage box 210 facing the solar panel 120, which can seal the storage box 210 and can be opened before the fixing roller 260 is moved out.

[0027] It should be noted that the water storage cylinder 270 is provided with a heat dissipation fin groove 271 located on the side of the heating rod 280, which can increase the contact area between the hot water in the water storage cylinder 270 and the silicone sleeve 290, thereby improving the heat dissipation efficiency.

[0028] On the other hand, the roller frame 250 is provided with a protective shell 251 located on the outside of the silicone sleeve 290, the front end of the protective shell 251 is hinged with a snow bouncing plate 252, and the inner side of the snow bouncing plate 252 is connected with an electric push rod 253 installed on the roller frame 250. Through the protective shell 251, the snow bouncing plate 252 and the electric push rod 253, when the snow is thick, the electric push rod 253 can be used to repeatedly drive the snow bouncing plate 252 to bounce upwards, so as to bounce away part of the accumulated snow, thereby reducing the workload of heating and melting the heating rod 280 and improving the snow removal efficiency.

[0029] Furthermore, a protective pad 254 is provided at the bottom of the snow-bounce plate 252 to prevent the bottom of the electric push rod 253 from touching the solar panel 120 and causing damage thereto, which is more reasonable.

[0030] The working principle and use process of the utility model are as follows: when snow removal is required, the servo motor 230 is first used to drive the winding roller 220 to rotate and loosen the traction rope 240, so that the fixed roller 260 rolls out of the storage box 210 and falls on the solar panel 120. At the same time, the heat generated by the heating rod 280 diffuses outward to melt the snow on the solar panel 120, so that the fixed roller 260 rolls toward the bottom along the surface of the solar panel 120. After all the snow is melted, the servo motor 230 drives the winding roller 220 to reverse and retract the fixed roller 260.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
