Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning technology, specifically to a double-sided photovoltaic panel cleaning device that can save water resources. Background Technology

[0002] Photovoltaic panels, also known as solar panels, are devices that directly convert solar energy into electrical energy using the photovoltaic effect that occurs in semiconductor materials under sunlight. It is one of the most direct ways to utilize solar energy. Most of the materials are silicon. In order to ensure the clean appearance of double-sided photovoltaic panels, cleaning equipment is needed to clean the surface of the double-sided photovoltaic panels.

[0003] Chinese Patent Publication No. CN215089605U discloses an automatic cleaning device for double-sided photovoltaic panels, including a base, a sliding plate, and a clamping and fixing mechanism. Electric telescopic columns are fixed to the right side of the top and the right side of the bottom of the support frame. The sliding plate is slidably connected to tracks on both the front and rear sides. The clamping and fixing mechanism is fixed to the front and rear inner walls of the support frame. A transparent plate is embedded in the front side of the support frame, and an electric drain valve is fixed through the front side of the bottom of the support frame. In this automatic cleaning device, after the double-sided photovoltaic panel has been spray-washed, it moves to the right between the clamping plates. The two clamping plates approach each other to clamp and fix the double-sided photovoltaic panel. Then, two rotating brushes approach each other until they are firmly attached to the upper and lower surfaces of the double-sided photovoltaic panel. The brushes then rotate while moving left or right to simultaneously clean the upper and lower surfaces of the double-sided photovoltaic panel, thereby increasing the cleaning intensity and improving the cleaning effect.

[0004] The aforementioned device filters used water using a filter screen and then recycles it, effectively saving water resources. However, when cleaning photovoltaic panels, impurities on their surface fall off with the water. These impurities can easily clog the filter screen's pores, slowing down the water flow and even making it impossible to collect and reuse wastewater. Utility Model Content

[0005] To address the aforementioned issues, a double-sided photovoltaic panel cleaning device that enables water conservation is provided. As the U-shaped frame moves along the electromagnetic slide rail, the lower contact ball at its bottom continuously contacts and collides with the upper contact ball at the top of the filter plate. Because the U-shaped frame's movement path covers the top of the filter plate, the lower contact ball sequentially strikes the upper contact balls at different positions. The impact force generated by the collision is transmitted to the filter plate. Combined with the elastic support of the spring telescopic rod, this causes the filter plate to vibrate at high frequency and small amplitude, shaking off impurities adhering to the surface of the filter holes, thus ensuring efficient wastewater filtration and recycling.

[0006] To address the problems of existing technologies, this utility model provides a double-sided photovoltaic panel cleaning device that can save water resources. The device includes a cleaning base, with mounting plates on both sides of the top of the cleaning base. A U-shaped frame is movably mounted on one side of each of the two mounting plates. A rotating shaft is rotatably mounted inside the U-shaped frame, and a cleaning roller for cleaning the photovoltaic panel is mounted outside the rotating shaft. A water spraying component for spraying water is also mounted inside the U-shaped frame.

[0007] Preferably, the top of the cleaning seat is provided with a plurality of spring telescopic rods, and the telescopic ends of the spring telescopic rods are provided with filter plates for filtering impurities in the water.

[0008] Preferably, the top of the cleaning seat is provided with a clamping seat for placing the photovoltaic panel.

[0009] Preferably, the water spray assembly includes a water spray pipe disposed inside the U-shaped frame, the inside of which is connected to a water supply pipe, and the inlet end of the water supply pipe is connected to an external water supply device.

[0010] Preferably, the side wall of the U-shaped frame is provided with symmetrical electromagnetic sliders, and the side wall of the mounting plate is provided with electromagnetic slide rails that cooperate with the electromagnetic sliders.

[0011] Preferably, a gear is provided at the top of the rotating shaft, and a rack that meshes with the gear is provided on the side wall of the mounting plate.

[0012] Preferably, the top of the filter plate is provided with a plurality of upper contact balls, and the bottom of the U-shaped frame is provided with lower contact balls that cooperate with the upper contact balls.

[0013] Preferably, the top of the cleaning seat is provided with a guide frame for guiding water flow, and the interior of the cleaning seat is movably provided with a water collection tank for collecting water resources.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. When the U-shaped frame moves along the electromagnetic slide rail, the lower contact ball at its bottom will continuously contact and collide with the upper contact ball at the top of the filter plate. Because the movement path of the U-shaped frame covers the top of the filter plate, the lower contact ball will hit the upper contact ball at different positions in sequence. The impact force generated by the collision is transmitted to the filter plate. With the elastic support of the spring telescopic rod, the filter plate will generate high-frequency small-amplitude vibration, shaking off the impurities attached to the surface of the filter holes, ensuring the efficiency of wastewater filtration and recycling.

[0016] 2. Driven by electromagnetic sliders and electromagnetic rails, the U-shaped frame can move stably along the mounting plate, driving the cleaning roller and water spray pipe to cover the entire surface of the panel. The rotation of the cleaning roller is achieved through the meshing of gears and racks, which ensures the uniformity of contact between the cleaning roller and the photovoltaic panel, effectively removing floating dust and stubborn stains from both sides of the panel, ensuring thorough and stable cleaning.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 6 As shown, this utility model provides:

[0026] A water-saving double-sided photovoltaic panel cleaning device includes a cleaning base 1. The cleaning base 1 has mounting plates 4 on both sides of its top. A U-shaped frame 6 is movably mounted on one side of each mounting plate 4. A rotating shaft 14 is rotatably mounted inside the U-shaped frame 6. A cleaning roller 12 for cleaning the photovoltaic panel is mounted outside the rotating shaft 14. A water spraying component for spraying water is also mounted inside the U-shaped frame 6.

[0027] The cleaning seat 1 provides a fixed base for the entire device, and the mounting plates 4 on both sides serve as the motion track carriers for the U-shaped frame 6.

[0028] The U-shaped frame 6 moves along the mounting plate 4, driving the cleaning roller 12 and the water spraying component to cover the entire surface of the photovoltaic panel, ultimately achieving double-sided cleaning without dead angles.

[0029] like Figure 5 As shown, the top of the cleaning seat 1 is provided with multiple spring telescopic rods 15, and the telescopic ends of the spring telescopic rods 15 are provided with filter plates 7 for filtering impurities in the water.

[0030] The wastewater generated after cleaning carries impurities such as dust and sand. It falls to the filter plate 7 by gravity. The filter plate 7 traps the impurities, allowing the clean water to flow downward through the filter holes.

[0031] The spring telescopic rod 15 provides elastic support for the filter plate 7.

[0032] like Figure 3 As shown, the top of the cleaning seat 1 is provided with a clamping seat 8 for placing photovoltaic panels.

[0033] Before cleaning, the photovoltaic panel is placed in the clamping seat 8 to restrict the position of the photovoltaic panel and prevent the photovoltaic panel from shifting due to the rotation friction of the cleaning roller 12 and the impact of water spray during the cleaning process.

[0034] After being positioned, the photovoltaic panel maintains a stable relative position with the cleaning roller 12 and the water spray pipe 13, ensuring that the cleaning roller 12 can evenly contact the panel surface and avoid incomplete cleaning or damage to the panel edges due to displacement.

[0035] like Figure 3 As shown, the water spray assembly includes a water spray pipe 13 installed inside the U-shaped frame 6. The water spray pipe 13 is connected to a water supply pipe 5, and the inlet end of the water supply pipe 5 is connected to an external water supply device.

[0036] External water supply equipment; a metering water pump delivers clean water through water pipe 5 to spray water pipe 13 inside U-shaped frame 6, which facilitates cleaning of photovoltaic panels.

[0037] like Figure 3 and Figure 6As shown, the side wall of the U-shaped frame 6 is provided with symmetrical electromagnetic sliders 18, and the side wall of the mounting plate 4 is provided with electromagnetic slide rails 11 that cooperate with the electromagnetic sliders 18.

[0038] By controlling the electromagnetic attraction between the electromagnetic slider 18 and the electromagnetic slide rail 11, the electromagnetic slider 18 is driven to move linearly along the electromagnetic slide rail 11. The electromagnetic slider 18 is fixedly connected to the U-shaped frame 6, and its movement synchronously drives the U-shaped frame 6 and the internal cleaning roller 12 and water spray pipe 13 to move, thereby realizing "mobile coverage cleaning".

[0039] like Figure 3 As shown, a gear 10 is provided on the top of the rotating shaft 14, and a rack 9 that meshes with the gear 10 is provided on the side wall of the mounting plate 4.

[0040] When the U-shaped frame 6 moves along the electromagnetic slide rail 11 via the electromagnetic slider 18, the gear 10 at the top of the rotating shaft 14 meshes with the rack 9 fixed on the mounting plate 4; the rack 9 remains stationary, while the gear 10 rolls as the U-shaped frame moves 6. When the gear 10 rolls, it drives the rotating shaft 14 to rotate, thereby driving the cleaning roller 12 to rotate and clean the photovoltaic panel.

[0041] like Figure 5 and Figure 6 As shown, the top of the filter plate 7 is provided with multiple upper contact balls 16, and the bottom of the U-shaped frame 6 is provided with lower contact balls 17 that cooperate with the upper contact balls 16.

[0042] When the U-shaped frame 6 moves along the electromagnetic slide rail 11, the lower contact ball 17 at its bottom will continuously contact and collide with the upper contact ball 16 at the top of the filter plate 7; because the moving path of the U-shaped frame 6 covers the top of the filter plate 7, the lower contact ball 17 will hit the upper contact ball 16 at different positions in sequence.

[0043] The impact force generated by the collision is transmitted to the filter plate 7, and with the elastic support of the spring telescopic rod 15, the filter plate 7 generates high-frequency small-amplitude vibration, shaking off the impurities attached to the surface of the filter holes, ensuring the efficiency of wastewater filtration and recycling.

[0044] like Figure 1 As shown, the top of the cleaning seat 1 is provided with a guide frame 3 for guiding water flow, and the interior of the cleaning seat 1 is provided with a water collection tank 2 for collecting water resources.

[0045] Wastewater generated during the cleaning process is contained by the guide frame 3 to prevent it from flowing around and being wasted. After being filtered by the filter plate 7, the wastewater flows into the water collection tank 2 inside the cleaning seat 1 along the inclined inner wall of the guide frame 3, which is convenient for later recycling.
