Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning technology, specifically a convenient photovoltaic panel cleaning scraper device. Background Technology

[0002] Dust and dirt on the surface of solar panels reduce light transmittance, directly affecting photoelectric conversion efficiency. Studies have shown that dust accumulation can lead to a decrease in power generation, and localized dirt or shading can cause localized temperature increases in photovoltaic modules, potentially posing a fire risk. Long-term contamination accelerates the aging of photovoltaic modules. To improve their power generation efficiency and extend their lifespan, photovoltaic solar panels need to be cleaned regularly.

[0003] Based on the above, the following problems were found: dust easily accumulates on the surface of photovoltaic panels, and the cleaning scraper is easily worn during cleaning, resulting in reduced cleaning efficiency. Traditional cleaning scrapers are usually a one-piece structure, which cannot be easily replaced and is inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a convenient photovoltaic panel cleaning scraper device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a convenient photovoltaic panel cleaning scraper device to solve the problems mentioned in the background art.

[0006] A portable photovoltaic panel cleaning scraper device includes an operating component, a cleaning component at one bottom end of the operating component, and a replacement component at the bottom of the cleaning component. The cleaning component includes a cleaning plate with two hinged ears at the top and a first positioning groove and a second positioning groove at the bottom. The replacement component includes a first positioning block and a second positioning block. A scraper is fixedly installed at the bottom of the first positioning block, and a brush is fixedly installed at the bottom of the second positioning block. The first positioning block and the second positioning block are respectively disposed inside the first positioning groove and the second positioning groove. Fixing slots are provided at both ends of the first positioning groove and at the four corners of the second positioning groove. Fixing inserts are provided at both ends of the top of the first positioning block and at the four corners of the top of the second positioning block. The fixing inserts are disposed inside the fixing slots, and each fixing insert is rotatably connected to a locking knob at its top.

[0007] By adopting the above technical solution, the operation components facilitate the use of the device by staff to clean photovoltaic panels. The replacement components facilitate the replacement of worn scrapers and brushes. The hinged ears facilitate the hinged connection between the cleaning components and the operation components, allowing the cleaning components to rotate and adjust their angle to fit the photovoltaic panels during use. The first and second positioning slots facilitate quick and easy positioning of the first and second positioning blocks, making it convenient to install the replacement components. The brush and scraper allow the brush to apply mechanical friction to remove sticky dirt remaining after water spraying, while the scraper removes wastewater and loose dirt. The fixed inserts and slots facilitate quick and easy fixing of the first and second positioning blocks inside the first and second positioning slots. The locking knob allows the fixed insert to be locked inside the slot after being inserted, thus securing the first and second positioning blocks firmly. This facilitates the use of the scrapers and brushes and allows for easy disassembly and replacement of the scrapers and brushes.

[0008] Furthermore, a third magnetic block is fixedly installed at both ends of the bottom of the locking knob, and a second magnetic block is fixedly installed at both ends of the top of the fixing block.

[0009] By adopting the above technical solution, the second and third magnetic blocks are designed to facilitate magnetic connection between the second and third magnetic blocks when installing the first and second positioning blocks, so that the locking knob remains parallel to the fixing block and can easily pass through the fixing slot.

[0010] Furthermore, a rotating groove is provided at the top of the fixed slot, and a first magnetic block is fixedly installed at both ends inside the rotating groove.

[0011] By adopting the above technical solution, the setting of the first magnetic block facilitates the magnetic connection between the first magnetic block and the third magnetic block after rotating the locking knob, thereby fixing the rotation angle of the locking knob and preventing the locking knob from losing its locking function during use.

[0012] Furthermore, a flow guide is fixedly installed on one side of the cleaning plate, a nozzle is fixedly installed at the bottom of the flow guide, and a water source interface is fixedly installed on one side of the flow guide.

[0013] By adopting the above technical solution and setting the water source interface, it is easy to connect to the external water source, and the guide device can evenly guide the water flow to the nozzle to spray it out, thereby rinsing the surface of the photovoltaic panel, softening the dirt and reducing subsequent friction loss.

[0014] Furthermore, a fixing block is fixedly installed on the top of the cleaning plate, the fixing block is located at the top of the first positioning groove, and a pressure spring is fixedly installed on one side of the fixing block.

[0015] By adopting the above technical solution and setting the fixing block, it is easy to fix the pressure spring.

[0016] Furthermore, the operating component includes a telescopic rod, one end of which is fixedly fitted with a hinge joint, and the other end of which is fitted with an anti-slip sleeve.

[0017] By adopting the above technical solution, the telescopic rod is equipped with a mechanical locking structure inside, which allows the telescopic rod to be adjusted in length and locked at a suitable length. This makes it convenient for staff to adjust the length of the device according to the installation height of the photovoltaic panels, adapting to different scenario requirements and improving operational convenience.

[0018] Furthermore, hinge components are fixedly installed at both ends of the hinge joint, and the hinge components are hinged to the hinge ears.

[0019] By adopting the above technical solution, the hinged parts are connected to the hinged ears, which facilitates the adjustment of the cleaning angle and adapts to the tilt or curvature of the photovoltaic panel surface.

[0020] Furthermore, a spring slide groove is provided in the middle of one side of the hinge joint, and the spring slide groove is located on the outside of the pressure spring.

[0021] By adopting the above technical solution, the setting of the spring slide groove facilitates the fixing of the angle of one end of the pressure spring, so that one end of the pressure spring always remains parallel to the telescopic rod. Thus, when the brush and scraper at the bottom of the cleaning plate are in contact with the photovoltaic panel, the cleaning plate rotates, causing the pressure spring to bend. This allows the pressure spring to provide elasticity to further press one end of the scraper, enabling the scraper to adhere tightly to the surface of the photovoltaic panel and improve the cleaning effect.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The design of the operating components facilitates the use of the device by workers to clean the photovoltaic panels; the design of the replacement components facilitates the replacement of worn scrapers and brushes; the design of the hinge ears facilitates the hinge connection between the cleaning components and the operating components, allowing the cleaning components to rotate and adjust their angle to fit the photovoltaic panels during use; the first and second positioning grooves facilitate quick and easy positioning of the first and second positioning blocks, making it convenient to install the replacement components; and the design of the brush and scraper allows the brush to apply mechanical friction to the sticky dirt remaining after water spraying, thus sweeping away the dirt. The scraper removes sewage and loose dirt. The fixed insert and slot design allows for quick and easy installation of the first and second positioning blocks inside the first and second positioning grooves. A locking knob allows the fixed insert to be inserted into the slot and then rotated to lock it securely, thus firmly fixing the first and second positioning blocks. This facilitates the use of the scraper and brush, and allows for easy disassembly and replacement of both. This invention improves cleaning convenience by allowing for easy disassembly and replacement of the scraper and brush, demonstrating high practical value. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6This utility model provides a technical solution: a convenient photovoltaic panel cleaning scraper device, including an operating component 1. The operating component 1 facilitates the use of the device by workers to clean photovoltaic panels. A cleaning component 2 is located at one end of the bottom of the operating component 1, and a replacement component 3 is located at the bottom of the cleaning component 2. The replacement component 3 facilitates the replacement of worn scraper blades 33 and brushes 34. The cleaning component 2 includes a cleaning plate 21, and two hinge ears 22 are located at the top of the cleaning plate 21. The hinge ears 22 facilitate the hinge connection between the cleaning component 2 and the operating component 1. The cleaning component 2 can be rotated and adjusted to fit the photovoltaic panel during use. The bottom of the cleaning plate 21 has a first positioning groove 211 and a second positioning groove 212. These grooves facilitate quick and easy positioning of the first positioning block 31 and the second positioning block 32, making it convenient to install the replacement component 3. The replacement component 3 includes a first positioning block 31 and a second positioning block 32. A scraper 33 is fixedly installed at the bottom of the first positioning block 31, and a brush 34 is fixedly installed at the bottom of the second positioning block 32. The brush 34 and scraper 33 facilitate the application of the brush... 34 applies mechanical friction to the sticky dirt remaining after water spraying, thus sweeping away the dirt. Scraper 33 scrapes away the sewage and loose dirt. The first positioning block 31 and the second positioning block 32 are respectively set inside the first positioning groove 211 and the second positioning groove 212. Fixing slots 29 are provided at both ends of the first positioning groove 211 and the four corners of the second positioning groove 212. Fixing inserts 35 are provided at both ends of the top of the first positioning block 31 and the four corners of the top of the second positioning block 32. The fixing inserts 35 are set inside the fixing slots 29. The setting of fixing inserts 35 and fixing slots 29 facilitates quick and easy cleaning. The first positioning block 31 and the second positioning block 32 are fixedly installed inside the first positioning groove 211 and the second positioning groove 212. The top of each fixing block 35 is rotatably connected to a locking knob 37. By setting the locking knob 37, it is easy to rotate the locking knob 37 after the fixing block 35 is inserted into the fixing slot 29 to lock the fixing block 35 inside the fixing slot 29, thereby firmly fixing the first positioning block 31 and the second positioning block 32, facilitating the use of the scraper 33 and the brush 34, and making it easy to disassemble and replace the scraper 33 and the brush 34.

[0032] The locking knob 37 has a third magnetic block 38 fixedly installed at both ends of its bottom, and the fixing block 35 has a second magnetic block 36 fixedly installed at both ends of its top. The second magnetic block 36 and the third magnetic block 38 are arranged to magnetically connect the second magnetic block 36 and the third magnetic block 38 when the first positioning block 31 and the second positioning block 32 are installed, so that the locking knob 37 and the fixing block 35 remain parallel and can easily pass through the fixing slot 29.

[0033] The top of the fixed slot 29 is provided with a rotating groove 27. The two ends of the rotating groove 27 are fixedly installed with first magnetic blocks 28. The first magnetic blocks 28 are provided so that the first magnetic blocks 28 and the third magnetic blocks 38 can be magnetically connected after the locking knob 37 is rotated, thereby fixing the rotation angle of the locking knob 37 and preventing the locking knob 37 from rotating and losing its locking function during use.

[0034] The cleaning plate 21 has a flow guide 25 fixedly installed on one side, a nozzle 210 fixedly installed at the bottom of the flow guide 25, and a water source interface 26 fixedly installed on one side of the flow guide 25. The water source interface 26 facilitates connection to an external water source, allowing the flow guide 25 to evenly guide the water flow to the nozzle 210 for spraying, thereby rinsing the surface of the photovoltaic panel, softening dirt and reducing subsequent friction loss.

[0035] The cleaning plate 21 has a fixing block 23 fixedly installed at the top. The fixing block 23 is located at the top of the first positioning groove 211. A pressure spring 24 is fixedly installed on one side of the fixing block 23. The fixing block 23 facilitates the fixing of the pressure spring 24.

[0036] The operating component 1 includes a telescopic rod 11. One end of the telescopic rod 11 is fixedly installed with a hinge joint 12, and the other end of the telescopic rod 11 is fitted with an anti-slip sleeve 13. Through the setting of the telescopic rod 11, a mechanical locking structure is provided inside the telescopic rod 11, so that the telescopic rod 11 can be adjusted in length and locked at a suitable length. This makes it convenient for staff to adjust the length of the device according to the installation height of the photovoltaic panel, adapt to different scenario requirements, and improve the ease of operation.

[0037] The hinge joint 12 has hinge pieces 14 fixedly installed at both ends. The hinge pieces 14 are hinged to the hinge ears 22. The hinge pieces 14 are hinged to the hinge ears 22, which facilitates the adjustment of the cleaning angle to adapt to the tilt or curvature of the photovoltaic panel surface.

[0038] The hinge joint 12 has a spring slide groove 15 in the middle of one side. The spring slide groove 15 is located on the outside of the pressure spring 24. The spring slide groove 15 makes it easy to fix the angle of one end of the pressure spring 24, so that one end of the pressure spring 24 is always parallel to the telescopic rod 11. When the brush 34 and scraper 33 at the bottom of the cleaning plate 21 are in contact with the photovoltaic panel, the cleaning plate 21 rotates, causing the pressure spring 24 to bend. The pressure spring 24 provides elastic force to further press one end of the scraper 33, so that the scraper 33 can stick tightly to the surface of the photovoltaic panel and improve the cleaning effect.

[0039] Specifically, the working principle of this portable photovoltaic panel cleaning scraper device is as follows: During use, the telescopic rod 11, with its internal mechanical locking structure, allows for length adjustment and locking at a suitable length. This facilitates adjustments to the device length based on the photovoltaic panel installation height, adapting to different scenarios and improving operational convenience. The hinge 14 connects to the hinge ear 22, allowing for easy adjustment of the cleaning angle to accommodate the tilt or curvature of the photovoltaic panel surface. The spring groove 15 allows for fixing the angle of one end of the pressure spring 24, ensuring that one end of the pressure spring 24 remains aligned with the telescopic rod 11. Maintaining parallelism, when both the brush 34 and scraper 33 at the bottom of the cleaning plate 21 are in contact with the photovoltaic panel, the cleaning plate 21 rotates, causing the pressure spring 24 to bend. This allows the pressure spring 24 to provide elasticity and further press one end of the scraper 33, ensuring the scraper 33 adheres tightly to the photovoltaic panel surface and improving cleaning efficiency. The water source interface 26 facilitates connection to an external water source, allowing the guide vane 25 to evenly direct water flow to the nozzle 210 for spraying, thereby rinsing the photovoltaic panel surface, softening dirt, and reducing subsequent frictional losses. The brush 34 and scraper 33 also facilitate the brush 34 to clean any residue left after spraying water. The sticky dirt is scraped off by mechanical friction. The scraper 33 removes the sewage and loose dirt. The fixed insert 35 and the fixed slot 29 facilitate quick and easy installation of the first positioning block 31 and the second positioning block 32 inside the first positioning groove 211 and the second positioning groove 212. The second magnetic block 36 and the third magnetic block 38 facilitate magnetic connection when installing the first positioning block 31 and the second positioning block 32, keeping the locking knob 37 parallel to the fixed insert 35, and facilitating its passage through the fixed slot 29. The design facilitates locking the fixed insert 35 inside the fixed slot 29 by rotating the locking knob 37 after inserting the fixed insert 35 into the fixed slot 29. This securely fixes the first positioning block 31 and the second positioning block 32, making it convenient to use the scraper 33 and the brush 34. It also allows for easy disassembly and replacement of the scraper 33 and the brush 34. The first magnetic block 28 allows the first magnetic block 28 to be magnetically connected to the third magnetic block 38 after rotating the locking knob 37, thus fixing the rotation angle of the locking knob 37 and preventing the locking knob 37 from losing its locking function during use.
