Description

Technical Field

[0001] This utility model relates to the field of solar panel cleaning technology, and more specifically, to a portable solar panel cleaning device. Background Technology

[0002] Solar photovoltaic panels are devices that directly convert sunlight into electrical energy and are widely used in residential, commercial, and industrial applications.

[0003] Solar photovoltaic panels are mainly installed outdoors, which makes it easy for dust in the outdoor air to accumulate and settle on the surface of the solar panels. Over time, this will affect the absorption of sunlight by the surface of the solar panels and affect the photoelectric conversion performance. Therefore, it is necessary to clean the solar panels regularly. A Chinese patent document with publication number CN113037208A discloses a small solar panel cleaning device. In the above solution, when cleaning the solar panel, water is sprayed first, then brushed by rotating a brush, and then scraped by a squeegee. With the above structure, the process of brushing the solar panel with a brush cannot wash off the dirt in time. It needs to be scraped off by the scraper at the back, which makes it easy for dirt to remain on the solar panel and adhere to the surface of the brush, thus affecting the brush's cleaning effect on the surface of the solar panel. Furthermore, after scraping the surface of the solar panel with a scraper, some water stains will remain on the surface. The above method cannot dry the remaining water stains in time, which makes it easy for dust to re-adhere to the water stains. Utility Model Content (a) Technical problems to be solved To address the problems existing in the prior art, this utility model provides a portable solar panel cleaning device to solve the technical problem mentioned in the background art of poor cleaning effect when using portable solar panel cleaning devices to clean solar panels.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A portable solar panel cleaning device includes a mobile trolley. A mounting frame is provided at the front of the mobile trolley, and a steam spray pipe is provided on the mounting frame. A cleaning brush is provided behind the steam spray pipe, and a drive structure is provided in conjunction with the cleaning brush. A flushing pipe is provided behind the cleaning brush, and a high-pressure nozzle is provided on the flushing pipe. A scraper is provided behind the flushing pipe, and a blower is provided behind the scraper. A blower head is provided on the blower.

[0005] The present invention is further configured to include a loading trolley, on which a steam generator is mounted. A steam delivery hose is provided between the steam generator and the steam spraying pipe. When the steam generator is started, steam can be delivered to the steam spraying pipe through the steam delivery hose, and the steam is sprayed onto the surface of the solar power panel to be cleaned through the steam spraying pipe, thereby softening the surface dust so that it can be cleaned by the subsequent brushing.

[0006] The present invention is further configured such that a water tank is provided on the loading trolley, a water pump is installed on the water tank, a diversion pipe is provided at the output end of the water pump, and a water supply hose is provided between the diversion pipe and the corresponding water inlet pipe and flushing pipe. When the water pump is started, water can be transported through the diversion pipe to the corresponding water supply hose under the action of the water pump, and then transported to the corresponding water inlet pipe and flushing pipe through the water supply hose, thereby realizing the water supply to the spray chamber and the flushing pipe. Here, a valve can be provided on the diversion pipe to control the opening and closing of the diversion pipe.

[0007] The present invention is further configured such that a fan is provided on the loading trolley, and an air supply hose is provided between the output end of the fan and the air blowing pipe. When the fan is started, the drying airflow can be delivered to the air blowing pipe through the air supply hose under the action of the fan, and then evenly blown onto the surface of the solar power panel through the blower head on the air blowing pipe, thereby realizing the drying after scraping, improving the surface cleaning effect of the solar power panel, and avoiding the situation where water stains remain and cause dust to re-adhere to the surface of the solar power panel.

[0008] The present invention is further configured such that mounting shafts are provided at both ends of the cleaning brush, the mounting shafts are mounted on the mounting frame by bearings, and one end extends outward, thereby achieving stable mounting of the cleaning brush on the mounting frame by the mounting shafts.

[0009] The present invention is further configured such that the driving structure includes a motor, the motor is disposed on the side of the mounting bracket, and a synchronous belt drive structure is provided between the output end and the extension end of the mounting shaft. When the motor is started, the rotation of the mounting shaft can be controlled by the cooperation of the motor and the synchronous belt drive structure. The rotation of the mounting shaft can control the rotation of the cleaning brush, thereby realizing the brushing and cleaning of the surface of the solar power panel.

[0010] The present invention is further configured such that a water spray chamber is provided inside the mounting shaft, and a water spray hole is provided extending outward from the water spray chamber. A water inlet pipe is rotatably installed inside the mounting shaft through a sealed bearing. The inner end of the water inlet pipe is connected to the water spray chamber. In use, water is delivered to the water spray chamber through the water inlet pipe and sprayed outward through the water spray hole. This allows water to be sprayed during the brushing process of the cleaning brush on the surface of the solar panel, thereby improving the softening and cleaning effect of dust and other particles on the surface of the solar panel and improving the cleaning performance of the solar panel surface. At the same time, the water flow sprayed from the water spray hole can rinse the bristles of the cleaning brush to ensure the cleanliness of the bristles.

[0011] The present invention is further configured such that a soft scraper head is provided at the bottom end of the wiper blade, a locking strip is provided at the top end of the soft scraper head, and a locking groove is provided at the bottom end of the wiper blade. The locking strip is locked in the locking groove. The soft scraper head can improve the scraping effect of the bottom of the wiper blade on the surface of the solar power panel after cleaning. The locking strip and locking groove can facilitate the installation, removal and replacement of the soft scraper head on the wiper blade.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a portable solar panel cleaning device, which has the following advantages: 1. This utility model incorporates a steam spray pipe. Between cleaning operations using the sweeping brush, a steam generator can be activated to deliver steam via a steam delivery hose to the steam spray pipe. The steam is then sprayed onto the surface of the solar panel to be cleaned, softening the surface dust for easier subsequent brushing. During this process, the steam cools down during transport, resulting in a lower temperature upon reaching the solar panel and preventing damage to its surface.

[0013] 2. This utility model features a cleaning brush located behind the steam spray pipe, equipped with a water spray pipe and spray holes. During use, the motor is started, and the rotation of the mounting shaft is controlled by the motor and synchronous belt drive structure. This rotation of the mounting shaft controls the rotation of the cleaning brush, thus achieving brushing and cleaning of the solar panel surface. Simultaneously, water is delivered to the spray chamber through the water inlet pipe and sprayed outwards through the spray holes. This allows water to be sprayed during the brushing process of the solar panel surface, improving the softening and cleaning effect of dust and other particles on the solar panel surface and enhancing the cleaning performance of the solar panel surface. During this process, the water sprayed from the spray holes can rinse the bristles of the cleaning brush, ensuring their cleanliness.

[0014] 3. This utility model has a water flushing pipe, a scraper, and a blower pipe arranged behind the cleaning brush. After the cleaning brush cleans the solar panel, the surface of the solar panel can be rinsed with water to remove residual impurities. Then, the scraper scrapes away any remaining water stains to prevent water stains from remaining. Finally, the blower dries the surface of the solar panel, further preventing water stains from remaining on the surface of the solar panel, improving the cleaning effect of the solar panel, and preventing secondary adhesion of dust due to water stains.

[0028] In summary: This invention incorporates a steam spray pipe 3. Between cleaning operations using the cleaning brush 4, the steam generator 11 can be activated to deliver steam via a steam delivery hose 12 to the steam spray pipe 3. The steam is then sprayed onto the surface of the solar panel to be cleaned, softening the surface dust for subsequent cleaning by the cleaning brush 4. During this process, the steam cools down to a certain extent during transport, resulting in a lower temperature upon reaching the solar panel and preventing damage to its surface. This invention features a cleaning brush 4 positioned behind the steam spray pipe 3, with a water spray pipe and water spray holes 23 on the cleaning brush 4. During use, the motor 20 is started, and the rotation of the mounting shaft 19 is controlled by the cooperation of the motor 20 and the synchronous belt drive structure 21. The rotation of the mounting shaft 19 controls the rotation of the cleaning brush, thus achieving brushing and cleaning of the solar panel surface. Simultaneously, water is delivered to the water spray chamber 22 through the water inlet pipe 24 and sprayed outwards through the water spray holes 23. This allows water to be sprayed during the brushing process of the solar panel surface, improving the softening and cleaning effect of dust and other particles on the solar panel surface and enhancing the cleaning performance of the solar panel surface. During this process, the water sprayed from the water spray holes 23 can rinse the bristles of the cleaning brush, ensuring the cleanliness of the bristles. This invention features a water-flushing pipe 5, a scraper 7, and a blower 8 arranged behind the cleaning brush 4. After the cleaning brush 4 cleans the solar panel, the water-flushing pipe 5 rinses the surface of the solar panel to remove residual impurities. Then, the scraper removes any remaining water stains, preventing water residue. Finally, the blower 8 dries the surface of the solar panel, further preventing water residue and improving the cleaning effect. This also prevents secondary adhesion of dust due to water residue.
