Technical Field
[0001] This utility model relates to the field of photovoltaic panel technology, specifically to a solar photovoltaic power generation dust removal device. Background Technology
[0002] Solar photovoltaic (PV) power generation is a technology that converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. It mainly consists of solar panels, PV inverters, battery banks, and controllers. The solar panels convert solar energy into direct current (DC), the inverter converts it into alternating current (AC), the battery stores the electrical energy, and the controller manages and controls the entire system. A solar PV dust removal device is specifically designed to clean dust from the surface of the solar PV panels.
[0003] According to announcement number CN222262657U, a solar photovoltaic power generation dust removal device is disclosed. This patent includes a solar panel, with two mounting drive assemblies arranged on the left and right sides of the bottom of the solar panel. A cleaning assembly is rotatably connected to the opposing surfaces of the two mounting drive assemblies. A scraping assembly is fixedly connected to the upper rear of the two mounting drive assemblies. The mounting drive assembly located on the right side includes a mounting block. A motor is fixedly connected to the bottom right side of the inner wall of the mounting block. A roller is fixedly connected to the output end of the motor, and the surface of the roller is rotatably connected to the bottom of the solar panel. This solar photovoltaic power generation dust removal device, as described in this utility model, uses a hand crank to rotate a threaded shaft, thereby threading the mounting frame up and down. This adjusts the vertical distance between the cleaning brush and the roller, and regulates the tension, improving the dust removal efficiency by increasing the tightness of the contact between the solar panel and the cleaning brush and scraper.
[0004] However, the aforementioned patent involves pushing a dry cleaning roller to move along the outer wall of the photovoltaic panel to remove the dirt adhering to the outer wall of the photovoltaic panel. However, this cleaning method has limited cleaning effect, and can only remove some dust and impurities on the surface of the photovoltaic panel. It is difficult to remove highly adhesive pollutants. Furthermore, when there are hard particles on the surface of the photovoltaic panel, the friction between the dry cleaning roller and the particles can easily cause scratches on the outer wall of the photovoltaic panel, thereby affecting the power generation of the solar photovoltaic panel. Utility Model Content
[0005] The purpose of this invention is to provide a solar photovoltaic power generation dust removal device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a solar photovoltaic power generation dust removal device, comprising a photovoltaic panel, a cleaning roller, and an auxiliary mechanism.

The auxiliary mechanism includes a track, a movable groove, a support base, a rainwater collection box, a limiting rod, a support plate, a fixing rod, a guide seat, a limiting pin, a spring, a cleaning scraper, and a fixing component. Tracks are welded to both sides of the middle of the photovoltaic panel, and movable grooves are opened inside the tracks. The middle of the movable groove is straight, and the bottom sides are inclined. A support base is fixedly connected to one side of the bottom of the photovoltaic panel, and a rainwater collection box is connected inside the support base. Limiting rods are connected to both sides of the outer wall of the cleaning roller, and a support plate is welded to the side of the limiting rods near the track.
[0007] Preferably, the outer wall of the cleaning roller has a limiting hole, and a limiting rod extends into it. The side of the limiting rod closest to the support plate extends into the movable groove, and the limiting rod and the support plate form an "L" shape.
[0008] Preferably, a fixing rod is welded to the top of the outer wall of the support plate, and a guide seat is slidably connected to one side of the outer wall of the fixing rod. A limit pin is welded to the side of the fixing rod away from the support plate, and the fixing rod and the limit pin form an "L" shape.
[0009] Preferably, the guide seat has limiting grooves on both sides of the middle part, and the limiting pins extend into them. A cleaning scraper is connected to the side of the guide seat away from the limiting pins, and the bottom end of the outer wall of the cleaning scraper contacts the outer wall of the cleaning roller.
[0010] Preferably, a spring is sleeved in the middle of the outer wall of the fixed rod, and the two sides of the outer wall of the spring are connected to the support plate and the fixed rod. The support plate, the fixed rod, the guide seat and the spring form an elastic telescopic mechanism.
[0011] Preferably, a fixing member is internally connected on the side of the track away from the support, and the fixing member has a "U" shaped structure.

[0021] 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.
[0022] Please see Figures 1-7This utility model provides a technical solution: a solar photovoltaic power generation dust removal device, including a photovoltaic panel 1, a cleaning roller 2, and an auxiliary mechanism 3. The cleaning roller 2 is connected to the outer wall of the photovoltaic panel 1. The auxiliary mechanism 3 includes a track 301, a movable groove 302, a support base 303, a rainwater collection box 304, a limiting rod 305, a support plate 306, a fixing rod 307, a guide seat 308, a limiting pin 309, a spring 310, a cleaning scraper 311, and a fixing member 312. The track 301 is welded to both sides of the middle part of the photovoltaic panel 1, and the track 301 is open inside. A movable groove 302 is provided, with a straight middle section and inclined sides at the bottom. A support base 303 is fixedly connected to one side of the bottom of the photovoltaic panel 1, and a rainwater collection box 304 is connected inside the support base 303. Limiting rods 305 are connected to both sides of the outer wall of the cleaning roller 2, and a support plate 306 is welded to the side of the limiting rod 305 near the track 301. Limiting holes are opened on the outer wall of the cleaning roller 2, and the limiting rods 305 extend into them. The side of the limiting rods 305 near the support plate 306 extends into the movable groove 302. The limiting rods 305 and the support plate 306 are connected. The support plate 306 has an "L" shaped structure; a fixing rod 307 is welded to the top of the outer wall of the support plate 306, and a guide seat 308 is slidably connected to one side of the outer wall of the fixing rod 307. A limit pin 309 is welded to the side of the fixing rod 307 away from the support plate 306, and the fixing rod 307 and the limit pin 309 form an "L" shaped structure; limit grooves are opened on both sides of the middle of the guide seat 308, and the limit pin 309 extends into them. A cleaning scraper 311 is connected to the side of the guide seat 308 away from the limit pin 309, and the bottom end of the outer wall of the cleaning scraper 311 is connected to the cleaning roller 2. The outer walls are in contact; a spring 310 is sleeved in the middle of the outer wall of the fixed rod 307, and the two sides of the outer wall of the spring 310 are connected to the support plate 306 and the fixed rod 307. The support plate 306, the fixed rod 307, the guide seat 308 and the spring 310 form an elastic telescopic mechanism; a fixing member 312 is connected inside the side of the track 301 away from the support seat 303, and the fixing member 312 has a "U" shaped structure; the limiting rod 305, the support plate 306 and the fixed rod 307 have a "U" shaped structure, and the cleaning roller 2 and the photovoltaic panel 1 are connected by rolling.
[0023] In practice, when cleaning the dust on the outer wall of the solar panel using a dust removal device, if it is found that there are no strongly adhesive pollutants on the top surface of the photovoltaic panel 1, the fixing part 312 is first manually moved upward so that its bottom is disengaged from the movable groove 302. Then, the guide seat 308 is manually pushed to move the fixing rod 307. Since the fixing rod 307 is connected to the limiting rod 305 through the support plate 306, and the limiting rod 305 extends into the cleaning roller 2, when the guide seat 308 is pushed to move the fixing rod 307, the limiting rod 305 will move along the movable groove 302 in the track 301, thereby moving the cleaning roller 2 together. At this time, the cleaning roller 2 is in a dry state. When it moves, it will rub against the outer wall of the photovoltaic panel 1, thereby removing the dust and impurities on the surface of the photovoltaic panel.
[0024] When photovoltaic panel 1 is found to have highly adhesive contaminants, such as bird droppings, tree sap, and oil stains, the guide seat 308 is pushed further to move the limiting rod 305 along the movable groove 302. Because the bottom of the movable groove 302 is inclined on both sides, the limiting rod 305 will move downwards when it reaches the bottom of the movable groove 302, causing the cleaning roller 2 to move down closer to the support seat 303 until the cleaning roller 2 enters the rainwater collection box 304. At this point, the cleaning roller 2 comes into contact with the water flow in the rainwater collection box 304. Then, the cleaning roller 2 is manually rotated to ensure full contact with the water flow. Since the cleaning scraper 311 is connected to the outer wall of the fixing rod 307, the bottom end of the cleaning scraper 311 contacts the cleaning roller 2, causing the cleaning roller 2 to rotate. The cleaning roller 2 will also rub against the bottom of the cleaning scraper 311, thereby scraping off the dirt on the outer wall of the cleaning roller 2 through the bottom of the cleaning scraper 311, preventing dirt from accumulating on the outer wall of the cleaning roller 2, thus reducing the replacement frequency of the cleaning roller 2. Then, the guide seat 308 is pushed to move the cleaning roller 2 closer to the fixing part 312. At this time, the wet cleaning roller 2 will wipe the outer wall of the photovoltaic panel 1, thereby removing stubborn stains on the surface of the photovoltaic panel 1, preventing stubborn stains from remaining, and preventing the use of the dry cleaning roller 2 to clean the photovoltaic panel 1. When hard particles remain on the surface of the photovoltaic panel 1, the dry cleaning roller 2 will rub against the particles, causing scratches on the outer wall of the photovoltaic panel 1, thereby reducing the impact of the photovoltaic panel 1 on power generation.
[0025] When the cleaning roller 2 needs to be replaced due to increased usage time, first manually pull the support plate 306 to move the limiting rod 305 and the fixing rod 307. Since the fixing rod 307 is connected to the limiting pin 309, the limiting pin 309 slides along the guide seat 308, thereby limiting the movement of the fixing rod 307. This allows the support plate 306 to move the limiting rod 305 smoothly. The movement of the support plate 306 will stretch the spring 310, causing it to deform until the limiting rod 305 is disengaged from the cleaning roller 2. Then, the limitation on the cleaning roller 2 is released, and it can be removed. After that, the intact cleaning roller 2 is moved under the guide seat 308. Then, the spring 310 resets, causing the support plate 306 to move, so that the limiting rod 305 is inserted into the cleaning roller 2, thereby limiting the cleaning roller 2. This eliminates the need to repeatedly turn multiple sets of bolts; the replacement can be completed simply by pulling the support plate 306, saving time and effort. This facilitates the replacement of the cleaning roller 2 and prevents stubborn stains from remaining when using a solar photovoltaic dust removal device.
[0026] In summary, when using this solar photovoltaic power generation dust removal device, if dust, leaves, or other debris accumulate on the outer wall of the photovoltaic panel 1 and needs to be cleaned, the cleaning roller 2 is manually pushed to move along the outer wall of the photovoltaic panel 1, thereby cleaning the dust and fallen leaves adhering to its surface and preventing them from affecting the light transmittance of the photovoltaic panel 1, which in turn affects the power generation efficiency of the photovoltaic panel 1. This is existing technology and will not be elaborated on here. The auxiliary mechanism 3 allows the moistened cleaning roller 2 to wipe the photovoltaic panel 1, thereby removing stubborn stains from the surface of the photovoltaic panel 1 and preventing stubborn stains from remaining. It can also prevent the outer wall of the photovoltaic panel 1 from being scratched by using a dry cleaning roller 2. Furthermore, there is no need to repeatedly turn multiple sets of bolts; simply pulling the support plate 306 is sufficient to replace the cleaning roller 2, saving time and effort. The contents not described in detail in this description are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
