[0002] Solar photovoltaic brackets are an important part of the solar photovoltaic power generation system. Their main function is to place, install and fix solar panels so that they can better receive sunlight and convert it into electrical energy.

[0003] However, when the solar photovoltaic brackets in the prior art are put into use, they will inevitably encounter rainy and snowy weather. Snowfall will cover the surface of the photovoltaic panels, reducing the power generation efficiency of the photovoltaic components.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1: Figure 1-8 As shown, the wind-resistant and damage-resistant connection bracket for solar photovoltaic panels proposed in this embodiment includes a base 2, brackets 3 are fixedly installed on both sides of the top of the base 2, the top of the bracket 3 is connected with a mounting plate 5 by bolts, and the top of the two mounting plates 5 is fixedly provided with a solar photovoltaic panel 1;

[0038] It should be noted that mounting holes 7 are provided on the outer walls of both sides of the base 2. When installing the solar photovoltaic panel 1, firstly, pre-embed bolts in the ground, and align the mounting holes 7 with the pre-embedded bolts to improve the stability and wind resistance of the solar photovoltaic bracket, and complete the preliminary installation of the solar photovoltaic bracket. Then, the solar photovoltaic panel 1 is installed above the two brackets 3 through two sets of mounting plates;

[0039] A control panel 4 is arranged in the middle of a bracket 3, a cleaning mechanism is arranged on the top of the solar photovoltaic panel 1, and a conveying mechanism is arranged below the solar photovoltaic panel 1;

[0040] The control panel 4 is internally provided with a processor, a data acquisition module, a data analysis module, a situation identification module and a signal execution module;

[0041] The data acquisition module is used to collect the pressure risk value F and the clean risk value H of the top wall of the solar photovoltaic panel 1 within the time threshold, and send the pressure risk value F and the clean risk value H to the data analysis module through the processor, and mark the working time of the solar photovoltaic panel 1 for 3 hours as the time threshold;

[0042] After receiving the pressure risk value F and the clean risk value H, the data analysis module immediately analyzes the situation of the top wall of the solar photovoltaic panel 1. The specific analysis process is as follows:

[0043] The pressure risk value F and the clean risk value H within the time threshold are obtained. The pressure risk value F is represented by the value received by the snow depth sensor on the top wall of the solar photovoltaic panel 1. The clean risk value H is represented by the total area covered on the top wall of the solar photovoltaic panel 1. According to the formula Q=(2F*a1+H*a2) / 2, where a1 and a2 are the preset proportional factors of the pressure risk value F and the clean risk value H, and a1 and a2 are both natural numbers greater than zero, the safety factor Q within the time threshold is obtained, and the preset safety factor stored and entered is immediately retrieved from the processor for comparison and analysis with the safety factor Q:

[0044] If the safety factor Q is greater than or equal to the preset safety factor, it is determined that the top of the solar photovoltaic panel 1 is abnormal, a risk signal is generated, and the risk signal is sent to the situation identification module through the processor. If the safety factor Q is less than the preset safety factor, no signal is generated;

[0045] It should be noted that the greater the pressure risk value F, the thicker the snow on the solar photovoltaic panel 1, the greater the damage to the solar photovoltaic panel 1, and the greater the clean risk value H, the more sludge on the solar photovoltaic panel 1, which affects the use of the solar photovoltaic panel 1.

[0046] When the situation identification module receives the risk signal, the processor synchronously sends the pressure risk value F and the clean risk value H that generate the risk signal to the situation identification module. After receiving the pressure risk value F and the clean risk value H, the situation identification module immediately retrieves the preset pressure risk value and the preset clean risk value stored and entered from the processor for comparison and analysis with the pressure risk value F and the clean risk value H;

[0047] If the pressure risk value F is greater than or equal to the preset pressure risk threshold, a snow removal signal is generated and sent to the signal execution module. After receiving the snow removal signal, the signal execution module immediately opens the control valve 2 87 and the water pump 84 to work;

[0048] If the pressure risk value F is less than the preset pressure risk threshold, no signal is generated;

[0049] If the clean risk value H is greater than or equal to the preset clean risk threshold, a cleaning signal is generated and sent to the signal execution module. After receiving the cleaning signal, the signal execution module immediately opens the control valve 3 89 and the water pump 84 to work;

[0050] If the clean risk value H is less than the preset clean risk threshold, no signal is generated.

[0055] A plurality of drain pipes 657 are disposed at the output end of the water tank 651, and the output ends of the plurality of drain pipes 657 are disposed toward the solar photovoltaic panel 1;

[0056] It should be noted that the water is discharged through several drainage pipes 657 at the output end of the water tank 651 to the glass plate on which there is no snow on the solar photovoltaic panel 1, so that the snow-melting agent penetrates downward along the bottom of the snow and impacts the snow, thereby accelerating the melting of the snow at the bottom of the snow-melting agent, and separating the bottom of the snow from the glass plate on the solar photovoltaic panel 1. Then, the power of the water pump 84 is controlled to be level two, so that the pressure in the limit tube 61 increases, and the piston 62 is continuously pushed, so that the movable plate continues to push the movable plate 652 downward, and the movable plate 652 pushes the melted snow at the bottom, and cooperates with the increased water pressure to further impact the snow on the glass plate, thereby accelerating the removal of snow on the solar photovoltaic panel 1 and improving the removal efficiency.

[0058] It should be noted that when the scraper 653 cooperates with the special-shaped limiting rod 654, the scraper 653 first moves in parallel, then moves upward, and then moves in parallel with the solar photovoltaic panel 1 again.

[0061] It should be noted that after receiving the cleaning signal, the control valve three 89, the control valve one 836 and the water pump 84 are opened, and the power of the water pump 84 is controlled to be level one. The clean water enters the upper delivery pipe 85 through the lower pumping pipe 88 and enters the limiting pipe 61, so that the water pressure pushes the piston 62, and pushes the movable plate 652 outward through the movable rod 63, so that the bottom of the scraper 653 is separated from the glass plate, and the water impacts the top of the glass plate through several drainage pipes 657 at the output end of the water tank 651, thereby completing the cleaning of the glass plate on the solar photovoltaic panel 1, avoiding the dirt on the glass plate from affecting the use efficiency of the solar photovoltaic panel 1, and improving the damage resistance of the solar photovoltaic panel 1.
