Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and more specifically, to a drainage and dust removal device for photovoltaic modules. Background Technology

[0002] In the field of solar photovoltaic power generation, photovoltaic modules are the core components, and their power generation efficiency is directly related to the performance and benefits of the entire photovoltaic system. Photovoltaic modules are usually composed of frames and photovoltaic panels. The frames not only play a role in fixing and protecting the photovoltaic panels, but also affect the overall structural strength of the module. In practical applications, in order to better receive sunlight, photovoltaic modules are often installed in an inclined manner. However, this tilted design presents a significant problem: since the frame thickness is typically greater than the photovoltaic panel thickness, a low point is formed at the junction of the photovoltaic panel and the top surface of the frame. During rainfall, rainwater flows along the surface of the photovoltaic panel, leaving water residue at this low point. Simultaneously, the rainwater washes away dust from the photovoltaic panel surface, causing dust to accumulate at the low point as well. Over time, this residual rainwater and dust gradually accumulate in this area, forming a dirt layer. The presence of this dirt layer affects the power generation efficiency of the photovoltaic module. A common solution is regular manual cleaning, but this method is labor-intensive. Therefore, we propose an improvement: a drainage and dust removal device for photovoltaic modules. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-4 A drainage and dust removal device for photovoltaic modules includes a mounting plate 1. A driving component is provided on the mounting plate 1. The driving component is connected to a fixing component, and the fixing component is connected to a first connecting pipe 201. One end of the first connecting pipe 201 is connected to a one-way valve 202. The end of the one-way valve 202 away from the first connecting pipe 201 is connected to a second connecting pipe 203. The second connecting pipe 203 is connected to a nozzle 204. The one-way valve 202 is unidirectionally openable towards the second connecting pipe 203. The one-way valve 202 is designed to prevent rainwater from flowing back into the nozzle 204. This application uses a first connecting pipe 201, the bottom of which can be fitted with a solenoid valve. The first connecting pipe 201 can be connected to an existing compressed air source through the solenoid valve. The compressed air source generates compressed air and sprays it out from the nozzle 204. By blowing air, rainwater and dust remaining at the lowest point of the top surface of the photovoltaic panel and frame are blown away, reducing the accumulation of rainwater and dust on the surface of the module, improving the power generation efficiency of the photovoltaic module, reducing power loss caused by dirt blockage, and reducing labor costs and labor intensity. The compressed air source is a compressor, and the start and stop of the waterproof motor 103 and the solenoid valve are all manually controlled. The drainage and dust removal operation of this application is carried out during the rain stop phase after rain.

[0020] In the diagram, point A is marked as the frame of the photovoltaic module, and point B is marked as the photovoltaic panel of the photovoltaic module.

[0021] Furthermore, the fastener includes a second clamp 205 disposed on the mounting plate 1. The side of the second clamp 205 is bolted to a first clamp 2. The first connecting pipe 201 is clamped between the first clamp 2 and the second clamp 205. The first connecting pipe 201 can be clamped and fixed by the cooperation of the first clamp 2 and the second clamp 205.

[0022] Furthermore, the driving component includes two mounting brackets 101 mounted on the mounting plate 1. A reciprocating screw 102 is rotatably connected between the two mounting brackets 101 via bearings. A slider 106 is provided on the outer surface of the reciprocating screw 102. A second clamp 205 is connected to the slider 106. The mounting brackets 101 are mounted on the mounting plate 1 by bolts. A waterproof motor 103 is mounted on one of the mounting brackets 101. One end of the waterproof motor 103 is connected to one end of the reciprocating screw 102 via a coupling. The waterproof motor 103 can drive the reciprocating screw 102 to rotate. During the rotation of the reciprocating screw 102, it can drive the slider 106 to move back and forth, thereby driving the first connecting pipe 201, the one-way valve 202, the second connecting pipe 203, and the nozzle 204 to move back and forth to adjust the position of the nozzle 204.

[0023] Furthermore, a groove is provided on the side of the slider 106 near the mounting plate 1, and a limiting roller 108 is provided in the groove. The limiting roller 108 is in rolling connection with the side of the mounting plate 1. A rotating shaft is inserted into the middle of the limiting roller 108, and the two ends of the rotating shaft are welded into the groove. The cooperation between the limiting roller 108 and the mounting plate 1 can limit the slider 106, making the slider 106 move more smoothly.

[0024] Furthermore, a first protective plate 104 is installed on the top of the mounting plate 1, and a second protective plate 105 is connected to one side of the first protective plate 104. The first protective plate 104 and the second protective plate 105 can protect the reciprocating screw 102 and reduce the possibility of the reciprocating screw 102 getting wet. The first protective plate 104 is located above the reciprocating screw 102 and the slider 106.

[0025] Furthermore, the mounting plate 1 is provided with mounting bolts 112, which are used to install the mounting plate 1 on the frame of the photovoltaic module. Threaded grooves are pre-set on the frame, and the mounting plate 1 is installed by the mutual cooperation of the mounting bolts 112 and the threaded grooves.

[0026] Furthermore, the mounting plate 1 is provided with several auxiliary components, including a notch 109 formed on the mounting plate 1. An insert plate 110 is fixedly installed on the inner wall of one side of the notch 109. A limiting plate 111 is also provided inside the notch 109. The limiting plate 111 is used to fix it to the frame of the photovoltaic module. The limiting plate 111 has a slot for the insert plate 110 to be inserted. The limiting plate 111 is pre-welded to the frame. After the insert plate 110 is inserted into the slot on the limiting plate 111, it can support the mounting plate 1, making it less likely to fall off during the disassembly and assembly of the mounting bolts 112, making the disassembly and assembly of the mounting plate 1 safer.

[0027] During disassembly, unscrew the mounting bolt 112, push the mounting plate 1 to separate the insert plate 110 from the slot, and remove the mounting plate 1 and other components. During installation, insert the insert plate 110 into the slot on the limiting plate 111 and then screw on the mounting bolt 112.
