Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component cleaning, and particularly relates to a portable photovoltaic component cleaning device. Background Art

[0002] Photovoltaic modules are an important solar power generation device, mainly composed of photovoltaic cells. These photovoltaic cells are usually thin sheets made of semiconductor materials. They work by converting solar energy into direct current electricity. They are an important part of solar photovoltaic systems. Photovoltaic modules are generally installed outdoors. After long-term use, the surface of photovoltaic modules is easily stained with a lot of dust. Dust covering the surface of photovoltaic modules will affect the transmittance of light, and then affect the power generation efficiency of photovoltaic panels. Therefore, it is very necessary to clean photovoltaic panels regularly, which helps to improve power generation efficiency, extend the service life of photovoltaic modules, reduce operation and maintenance costs, and ensure the stable operation of the system.

[0003] Existing photovoltaic module cleaning devices are generally of an integrated design. If the brush rod is too long, it will be difficult to carry and move the cleaning device. If the brush rod is too short, it will not be able to clean photovoltaic modules with a large area. In addition, after the photovoltaic module is cleaned, some moisture will remain on the surface of the photovoltaic module. At this time, the surface of the photovoltaic module is very easy to adhere to fine dust particles, thus affecting the cleaning effect. Utility Model Content

[0031] like Figures 1 to 5 As shown, the utility model provides a portable photovoltaic module cleaning device, comprising:

[0032] Support rod 10;

[0033] The photovoltaic cleaning brush comprises a brush plate 20 and a cleaning brush 21 mounted on the bottom end surface of the brush plate 20, and the top of the brush plate 20 is rotatably mounted on one side of the front end of the support rod 10 through a rotating pair;

[0034] A plurality of splicing rods 30, which are detachably spliced ​​and connected end to end and then detachably mounted on the support rod 10, so as to extend the length of the support rod 10;

[0035] The wiper strip 40 is mounted at the bottom on the other side of the front end of the support rod 10 through a supporting frame 50, so that the wiper strip 40 and the photovoltaic cleaning brush are relatively distributed at the front end of the support rod 10, and a cleaning spray head 60 is installed in the middle of the supporting frame 50.

[0036] The support rod 10 of the utility model is used to install a photovoltaic cleaning brush and a wiper strip 40. The photovoltaic cleaning brush and the wiper strip 40 are installed on the opposite sides of the front end of the splicing rod 30, so that one side of the cleaning device is used for cleaning and the other side is used for wiping. The plurality of splicing rods 30 of the utility model can be detachably spliced ​​and connected head to tail, and then detachably connected to the rear end of the support rod 10. By adjusting the number of splicing rods 30 installed at the rear end of the support rod 10, the length of the portable photovoltaic module cleaning device of the utility model can be adjusted, so that the application can not only be used for cleaning photovoltaic modules with a large area, but also does not require the aid of auxiliary tools such as ladders. The cleaning personnel do not need to climb high to clean the photovoltaic modules installed at a high place by installing the splicing rod 30; and after removing the splicing rod 30, it is convenient to store and carry the cleaning device. The application also installs a wiper strip 40 on the support rod 10. After cleaning, the wiper strip 40 can well remove the liquid remaining on the surface of the photovoltaic module, so as to achieve cleaning on one side and wiping on the other side, thereby improving the use effect of the portable photovoltaic module cleaning device of the utility model. By installing the cleaning water spray head 60 in the middle of the supporting frame 50, the supporting frame 50 provides an installation base for the cleaning water spray head 60 and the wiper strip 40 at the same time, and the structure is simple; the cleaning water spray head 60 can spray the cleaning liquid on the surface of the photovoltaic module when the photovoltaic cleaning brush cleans the photovoltaic module, which can improve the cleaning effect of the surface of the photovoltaic module.

[0037] In some embodiments, Figure 2 and Figure 3 As shown, a connecting plate 11 is provided at the bottom of the front end of the support rod 10, and a first internal threaded hole 12 is provided at the rear. A clamping portion 22 for clamping the connecting plate 11 is provided at the top of the brush plate 20, and the clamping portion 22 is rotatably connected to the connecting plate 11 through a fixed shaft 23. By rotatably connecting the photovoltaic cleaning brush to the front end of the support rod 10, when cleaning the photovoltaic module, the brush plate 20 can be freely rotated according to the position of the photovoltaic module and the operating angle of the cleaning personnel, which can not only improve the convenience of the cleaning personnel's operation, but also can clean the corners of the photovoltaic module that are difficult to clean, thereby improving the cleaning effect.

[0038] In some embodiments, Figure 3As shown, the front end of the splicing rod 30 is provided with a threaded column 31 adapted to the first internal threaded hole 12, and the rear end is provided with a second internal threaded hole 32 adapted to the threaded column 31.

When waterless cleaning is performed, the fastener 54 can be removed to remove the carrier 50 and the wiper strip 40. A dovetail strip 52 perpendicular to the rod direction of the support rod 10 is arranged on the top of the carrier frame 50, and a dovetail groove 41 adapted to the dovetail strip 52 is opened at the bottom of the wiper strip 40, and the wiper strip 40 is installed on the dovetail strip 52 through the dovetail groove 41.

By moving the support rod 10, the cleaning brush 21 moves back and forth on the photovoltaic module to clean the photovoltaic module. After cleaning, Figure 4 As shown, the support rod 10 is rotated to make the wiping edge 42 of the wiper strip 40 contact the photovoltaic module. By moving the support rod 10 to make the wiping edge 42 of the wiper strip 40 move on the photovoltaic module, the liquid remaining on the surface of the photovoltaic module can be cleared.

[0042] As a preferred embodiment, the wiper strip 40 is a rubber strip, and at least one side of the wiper strip 40 is set as a slope, so that the wiper strip 40 and the photovoltaic module form an acute-angle contact edge, so that the wiper strip 40 fits tightly with the surface of the photovoltaic module to improve the wiping effect and efficiency.

[0043] In some embodiments, Figure 2 and Figure 3 As shown, a third internal threaded hole 53 is provided in the middle of the support frame 50, and an external thread matching the third internal threaded hole 53 is provided on the outer wall of the cleaning water spray head 60. The water spraying end (front end) of the cleaning water spray head 60 passes through the third internal threaded hole 53 toward the front end of the support rod and is threadedly fixedly connected to the support frame 50. A flexible water pipe 61 for connecting a water supply pipe is provided at the rear end of the cleaning water spray head 60. By installing a cleaning water spray head 60 on the supporting frame 50, the cleaning water spray head 60 is connected to an external water supply pipe through a flexible water pipe 61, so that the cleaning liquid can be sprayed on the surface of the photovoltaic module, thereby improving the cleaning effect of the surface of the photovoltaic module; the flexible water pipe 61 can be bent and deformed arbitrarily to facilitate changing different water spray angles during cleaning; the cleaning water spray head 60 is directly installed on the supporting frame 50, not only does it not need to set up an additional installation space for the cleaning water spray head 60, making the device simpler and more convenient, but the supporting frame 50 is an inclined plate, so that the water spray end of the cleaning water spray head 60 can be directly facing the photovoltaic cleaning brush, and the cleaning liquid can be sprayed under the cleaning brush 21 to improve the cleaning effect.

[0044] As a preferred embodiment, a regular hexagonal ring plate 62 is provided at the end of the external thread on the outer wall of the cleaning water spray head 60, which facilitates the disassembly and assembly of the cleaning water spray head 60 by rotating it with a tool, thereby improving the stability and tightness of the installation.

[0045] As a preferred embodiment, the outer surfaces of the support rod 10 and the splicing rod 30 are both frosted surfaces or provided with anti-slip patterns to increase the friction between the outer circumferential surfaces of the support rod 10 and the splicing rod 30 and the hands of the cleaning personnel, thereby facilitating the grasping and operation of the cleaning personnel and preventing slippage during grasping.
