Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, and in particular to a photovoltaic panel cleaning device. Background Technology

[0002] With the active support of government policies for the photovoltaic industry, the application scenarios of photovoltaic modules are gradually expanding. The cleaning and maintenance of photovoltaic panels has become a key link in ensuring power generation efficiency. Cleaning equipment is used to remove dirt such as dust, snow, and bird droppings from the surface of photovoltaic panels, thereby improving the power generation efficiency of photovoltaic panels.

[0003] Currently, most existing cleaning equipment uses a single structure for its cleaning modules, which only use roller brushes to clean photovoltaic panels. The cleaning effect is limited. Adding structures to the cleaning brush is insufficient for cleaning water stains. For example, adding a reverse spiral structure to the cleaning brush can throw the sewage out at multiple angles, effectively avoiding cleaning dead corners and sewage accumulation. However, it cannot completely scrape off the residual water film. After drying, water stains will form. Especially in low-temperature areas during winter, the residual water film is prone to freezing, which reduces the solar energy absorption rate of the photovoltaic panels and affects the power generation efficiency.

[0004] Therefore, given the single structure of existing photovoltaic panel cleaning equipment and the inability to completely remove residual water stains, a new photovoltaic panel cleaning equipment can be designed. This equipment can achieve a complete cleaning process of sweeping, rinsing, and drying through a dual-module cleaning method, thereby improving the cleaning effect and reducing water stain residue. Utility Model Content

[0005] To overcome the problem that most photovoltaic panel cleaning equipment has a simple cleaning structure and limited cleaning effect, taking the anti-spiral cleaning brush as an example, although it can throw out sewage, it cannot completely remove the water film, resulting in water stains remaining on the surface of the photovoltaic panel.

[0006] The technical solution of this utility model is as follows: a photovoltaic panel cleaning device, including a protective shell installed on the outside of the main body of the cleaning device, and a main cleaning component and an auxiliary cleaning component; the main cleaning component includes a roller brush and a linkage mechanism, the linkage mechanism is rotatably connected to both sides of the protective shell near the head, the roller brush is rotatably connected to the head of the protective shell through the linkage mechanism, and the main cleaning component is used to brush the photovoltaic panel; the auxiliary cleaning component includes a water-absorbing roller and a scraper, a groove is opened at the bottom end of the protective shell near the tail, the water-absorbing roller is rotatably connected in the groove, the scraper is set near the water-absorbing roller and close to the bottom of the protective shell, the angle opening with the protective shell faces the roller brush, and the auxiliary cleaning component is used to clean dirt and scrape off residual water.

[0007] Preferably, the system also includes a moving component, which includes tracks, a first connector, and a motor. Tracks are symmetrically mounted along the axis in the middle of the protective housing. The first connector is engaged with the inner side of the tracks. The motor is electrically connected to the inner side of the first connector. The motor is installed inside the protective housing. The tracks on the left and right sides are driven independently by two sets of motors.

[0008] Preferably, the mobile component also includes a second connector and a bearing. The second connector is connected to the inner side of the track. A bearing is installed at one end of the second connector, and a third connector is rotatably connected to the other end of the bearing. One end of the third connector is fixed to the bottom of the protective housing.

[0009] Preferably, the device also includes a spring, with a first fixing member fixedly connected to both sides of the protective housing near the linkage mechanism, and a second fixing member fixedly connected to the inside of the linkage mechanism, the first fixing member being connected to the second fixing member via a spring.

[0010] Preferably, it also includes a water supply component, which includes a water tank and a water outlet pipe. A removable water tank is snapped into the inside of the protective housing, and a water outlet pipe is installed on the side of the water tank near the roller brush.

[0011] Preferably, the water supply assembly also includes a spray head, with a spray head installed at the other end of the water outlet pipe. The spray head has multiple sets of water outlet holes distributed along the long side of the side facing the roller brush, and the length of the spray head is consistent with the axial length of the roller brush.

[0012] The beneficial effects of this utility model are: Compared to existing photovoltaic panel cleaning equipment, when the dry cleaning mode is activated, the cleaning equipment moves to drive the roller brush to clean and absorb fine dust. When the cleaning equipment moves forward, the scraper removes hard dirt. When the wet cleaning mode is activated, the roller brush is wetted to clean the photovoltaic panel. The scraper removes most of the residual wastewater. Finally, the water suction roller is used to dehydrate the panel, ensuring that the surface of the photovoltaic panel is dry and free of water stains. The dual cleaning module design improves the cleaning effect, effectively removes water stains, and improves power generation efficiency. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please see Figure 1 and Figure 4 This utility model provides an embodiment: a photovoltaic panel cleaning device, including a protective shell 1, which is installed on the outside of the main body of the cleaning device, and also includes a main cleaning component and an auxiliary cleaning component; the main cleaning component includes a roller brush 3 and a linkage mechanism 4, the linkage mechanism 4 is rotatably connected to both sides of the protective shell 1 near the head, the roller brush 3 is rotatably connected to the head of the protective shell 1 through the linkage mechanism 4, and the main cleaning component is used to brush the photovoltaic panel; the auxiliary cleaning component includes a water absorption roller 5 and a scraper 6, a groove is opened at the bottom end of the protective shell 1 near the tail, the water absorption roller 5 is rotatably connected in the groove, the scraper 6 is set near the water absorption roller 5 and close to the bottom of the protective shell 1, the angle opening of the scraper 6 with the protective shell 1 faces the roller brush 3, and the auxiliary cleaning component is used to clean dirt and scrape off residual water.

[0017] Among them, roller brush 3 uses ultra-fine fiber soft bristles, which can adsorb fine dust. The scraper 6 is made of stainless steel and can remove both hard dirt and most wastewater. The water-absorbing roller 5 uses a microporous sponge, which follows the scraper 6 to absorb the remaining water, ensuring that there are no water stains on the surface of the photovoltaic panel. When the cleaning equipment moves, the linkage mechanism 4 pushes the roller brush 3 to rotate and clean the photovoltaic panel. When the dry cleaning mode is activated, the roller brush 3 adsorbs fine dust, and the cleaning equipment continues to move forward. The scraper 6 scrapes off hard dirt. When the wet cleaning mode is activated, the roller brush 3 is wetted with water mist and rolled to clean the photovoltaic panel. As the cleaning equipment moves, most of the remaining sewage is scraped off by the scraper 6, and the water suction roller 5 rolls to absorb the remaining water immediately after the scraper 6.

[0018] Please see Figure 2 and Figure 3In this embodiment, a moving component is also included. The moving component includes a track 2, a first connector 201 and a motor 202. The track 2 is symmetrically installed along the axis in the middle of the protective shell 1. The first connector 201 is engaged with the inner side of the track 2. The motor 202 is electrically connected to the inner side of the first connector 201. The motor 202 is installed inside the protective shell 1. The left and right tracks 2 are driven independently by two sets of motors 202. The moving component also includes a second connector 203 and a bearing 204. The second connector 203 is connected to the inner side of the track 2. The bearing 204 is installed at one end of the second connector 203. The third connector 205 is rotatably connected to the other end of the bearing 204. One end of the third connector 205 is fixed to the bottom of the protective shell 1.

[0019] Among them, track 2 adopts a herringbone pattern, which can provide strong grip and prevent slipping on the photovoltaic panel surface; Two sets of motors 202 independently drive the left and right tracks 2, using differential speed to achieve steering, making it easier for the cleaning equipment to turn on the photovoltaic panels; When the motor 202 is started, it drives the first connecting member 201 to rotate, which in turn drives the track 2 to rotate. The rotation of the track 2 drives the second connecting member 203 to rotate. The second connecting member 203 drives the third connecting member 205 to move through the bearing 204. The third connecting member 205 drives the cleaning equipment body to move.

[0020] Please see Figure 3 and Figure 4 In this embodiment, a spring 401 is also included. First fixing members 402 are fixedly connected to both sides of the protective shell 1 near the linkage mechanism 4, and second fixing members 403 are fixedly connected to the inner side of the linkage mechanism 4. The first fixing member 402 is connected to the second fixing member 403 through the spring 401.

[0021] When the roller brush 3 cleans the photovoltaic panel, it applies pressure to the surface of the panel. The reaction force pushes the roller brush 3, which drives the linkage mechanism 4 to rotate upward. This causes the second fixing member 403 to squeeze the spring 401, and the spring 401 to squeeze the first fixing member 402, thereby adjusting the contact pressure between the roller brush 3 and the photovoltaic panel to ensure that it is always in close contact with the surface of the photovoltaic panel.

[0022] Please see Figure 1 and Figure 5 In this embodiment, a water supply component is also included. The water supply component includes a water tank 7 and a water outlet pipe 702. A detachable water tank 7 is snapped into the inside of the protective housing 1. The water outlet pipe 702 is installed on the side of the water tank 7 near the roller brush 3. The water supply assembly also includes a spray head 701. The other end of the water outlet pipe 702 is equipped with a spray head 701. The spray head 701 has multiple sets of water outlet holes distributed along the long side of the side facing the roller brush 3. The length of the spray head 701 is consistent with the axial length of the roller brush 3.

[0023] Fill the water tank 7 with water, attach it to the inside of the protective housing 1, start the water supply system, draw the water from the water tank 7 into the water outlet pipe 702, and spray it out from the water outlet of the spray head 701 through the water outlet pipe 702 to wet the roller brush 3.

[0024] Through the above steps, when the dry cleaning mode is activated, the cleaning equipment moves to drive the roller brush 3 to sweep and absorb fine dust. When the cleaning equipment moves forward, the scraper 6 removes hard dirt. When the wet cleaning mode is activated, the roller brush 3 is wetted to clean the photovoltaic panel. The scraper 6 removes most of the residual wastewater. Finally, the water suction roller 5 is used to dehydrate the photovoltaic panel, ensuring that the surface of the photovoltaic panel is dry and free of water stains. The dual cleaning module design improves the cleaning effect, effectively removes water stains, and improves power generation efficiency.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
