Description

Technical Field

[0001] The utility model relates to the technical field of new energy batteries, in particular to a photovoltaic component with a dust removal function. Background Art

[0002] The utilization of light energy, especially solar energy, mainly includes solar thermal power generation and photovoltaic power generation. Solar thermal power generation uses reflectors to focus solar energy to a hot melt tower, and uses the hot melt tower to generate thermal energy. Photovoltaic power generation mainly uses solar panels, also known as photovoltaic panels, which are photoelectric semiconductor sheets that can directly convert the solar energy irradiated on them into electrical energy. Photovoltaic panels are outdoor power generation structures. They are easily obstructed by long-term outdoor installation and placement. Obstructions include dust, debris, etc. Dust and debris will reflect and block sunlight, reduce the intensity of light that the photovoltaic panel can receive, and thus reduce the power generation efficiency of the photovoltaic panel. In some solar photovoltaic power plants, special cleaning personnel are required, so users need to regularly clean the obstacles that block the sunlight on the surface of the solar panels. In some solar photovoltaic power plants that do not have automated cleaning equipment, cleaning personnel are required to manually remove dust and debris on the surface of the photovoltaic panels with a mop. Usually, a row of photovoltaic panels can be several meters long, which is far longer than the length of general tools, and there is a problem of difficulty in manual cleaning. Utility Model Content

[0042] like Figure 1-3 A photovoltaic assembly with a dust removal function is shown, and the photovoltaic assembly includes a photovoltaic panel group 1, a guide rail assembly 2, a dust removal assembly 3, and a manual traction member 4. Specifically, the photovoltaic panel group 1 includes at least one photovoltaic panel arranged in a straight line. Usually, the photovoltaic panel group 1 is a row of photovoltaic columns installed at an angle. The guide rail assembly 2 is arranged at the edge of the photovoltaic panel group 1, and is used to guide the dust removal assembly 3 to move smoothly and steadily to improve the dust removal efficiency. The dust removal assembly 3 spans the photovoltaic panel group 1, and the dust removal assembly 3 is connected to the guide rail assembly 2, and moves along the arrangement direction of the photovoltaic panels under the guidance of the guide rail assembly 2, and is used to clean the dust on the photovoltaic panel group 1. The manual traction member 4 is connected to the dust removal assembly 3 to pull the dust removal assembly 3 to move on the surface of the photovoltaic assembly.

[0043] In this embodiment, a guide rail assembly 2, a dust removal assembly 3 and a manual traction member 4 are provided on the basis of the photovoltaic panel group 1. The dust removal assembly 3 is driven by the manual traction member 4 to move on the photovoltaic panel group 1, so that the dust and debris on the surface of the photovoltaic panel group 1 can be cleaned with the help of the dust removal assembly 3. The dust removal assembly 3 is guided by the guide rail assembly 2 to move smoothly and conveniently. In this way, the dust on the surface of the photovoltaic panel can be simply and conveniently removed, thereby improving the power generation efficiency of the photovoltaic panel.

[0044] For the guide rail assembly 2, specifically, there are two groups of guide rail assemblies 2, and the two groups of guide rail assemblies 2 are respectively arranged on the two side edges of the photovoltaic panel group 1 in the straight direction, and the two ends of the dust removal assembly 3 are respectively connected to the two groups of guide rail assemblies 2, so that the movement stability and smoothness of the dust removal assembly 3 can be improved.

[0045] In the following embodiment of the dust removal assembly 3, the dust removal assembly 3 includes a mounting block 31, a connecting rod 32 and a brush 33. The number of the mounting blocks 31 is two. The two mounting blocks 31 are respectively arranged on the two sets of guide rail assemblies 2. Specifically, the mounting blocks 31 are arranged on the corresponding sliders 21. The upper part of the mounting block 31 is provided with a mounting hole 311. The two ends of the connecting rod 32 are respectively connected to the two mounting blocks 31. The two ends of the brush 33 are respectively rotatably mounted on the mounting holes 311. In the dust removal assembly 3, a stable support structure that spans the photovoltaic panel group 1 is formed by the mounting block 31 and the connecting rod 32. The brush 33 spans the photovoltaic panel group 1 and is installed on the support structure. The two ends of the brush 33 are respectively rotatably mounted on the two mounting blocks 31, so as to realize the rotation of the brush 33, so that the brush 33 can be turned over to brush the photovoltaic panel when moving in different directions.

[0046] Furthermore, the brush 33 is detachably mounted. Specifically, a through gap 312 extending to the mounting hole 311 is provided on the top of the mounting block 31 , and the width of the through gap 312 is smaller than the diameter of the mounting hole 311 .

[0047] Both ends of the brush 33 are provided with mounting shafts 331 , and the side surfaces of the mounting shafts 331 are provided with planes 332 for reducing the size, and the minimum width of the mounting shafts 331 is less than or equal to the width of the gap 312 .

[0048] In this way, the rotatable brush 33 can be installed on the mounting block 31 in an inclined or straight state and during the brushing operation without falling off. Also, the plane 332 on the mounting shaft 331 of the brush 33 is parallel to the side of the through gap 312, so that the mounting shaft 331 can enter the through gap 312 with a minimum width, thereby facilitating the mounting shaft 331 to enter the mounting hole 311 through the through gap 312, or to be removed and installed through the through gap 312, thereby realizing the disassembly and installation of the brush 33, and facilitating the cleaning and replacement of the brush 33.

[0049] In some embodiments of the brush 33, a traction ring 333 is provided in the middle of the edge of the brush 33. The manual traction member 4 is detachably connected to the traction ring 333.

[0050] In some embodiments, wedge-shaped debris removal blades 321 are provided on both sides of the lower part of the connecting rod 32. When the connecting rod 32 is like this, the wedge-shaped debris removal blades 321 can scrape off debris on the surface of the photovoltaic panel, especially some firmly adhered sand, bumps, stones, etc., thereby further improving the working effect of the dust removal component 3.

[0051] In some embodiments of the guide rail assembly 2, the guide rail assembly 2 includes a slider 21 and a plurality of guide rails 22, the plurality of guide rails 22 are arranged in a straight line, and the slider 21 is slidably disposed on the guide rails 22. The dust removal assembly 3 is connected to the slider 21.

[0052] Furthermore, a positioning hole 221 is provided at the end of the guide rail 22. The guide rail assembly 2 also includes a positioning pin 23, and both ends of the positioning pin 23 extend into the positioning holes 221 of the adjacent guide rails 22 respectively. A groove is provided on the back edge of the photovoltaic panel, and the guide rail 22 is set in the groove. In this embodiment, the positioning pin 23 is provided to calibrate the two adjacent backs so that the guide rails 22 are aligned with each other, avoiding installation deviation of the adjacent guide rails 22, and improving the smoothness of the movement of the slider 21.

[0053] In some embodiments of the manual traction member 4, the manual traction member 4 is a traction rope, which is connected to the dust removal assembly 3. Specifically, the middle part of the traction rope is connected to the aforementioned traction ring 333, and the two ends of the traction rope respectively extend to the two ends of the photovoltaic panel group 1. The two ends of the traction rope respectively pull the dust removal assembly 3 to move in two directions. For example, one end of the traction rope pulls the dust removal assembly 3 to move for dust removal, and the other end of the traction rope pulls the dust removal assembly 3 to reset for dust removal.

[0054] In addition, the two ends of the traction rope can be connected together, so that the traction rope forms a rope loop, and the rope is wrapped around the photovoltaic panel group 1. In this way, the dust removal component 3 can be moved and reset by simply standing in the same position and pulling the rope loop in both directions.

[0055] Two guide wheels 5 for guiding the movement of the traction rope are also provided at both ends of the photovoltaic panel group 1. The traction rope passes through the guide wheels 5. The guide wheels 5 are used to guide the traction rope to move with low friction and low resistance, thereby improving the convenience of manual dust removal.

[0056] Of course, the manual traction member 4 can also be a long rod, and the end of the long rod is detachably connected to the dust removal assembly 3, specifically, the long rod is detachably connected to the traction ring 333. In the process of dust removal, the dust removal assembly 3 is pushed to move by the long rod.

[0057] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
