Description

Technical Field

[0001] This utility model relates to a remote-controlled cleaning machine for photovoltaic panels, belonging to the field of photovoltaic panel cleaning technology. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft that are controlled by radio remote control equipment or their own program control devices. They do not require personnel and have a wide range of applications in aerial photography, agricultural plant protection, express delivery, disaster relief, environmental monitoring, power line inspection, surveying and mapping, and film and television production.

[0003] The main methods for cleaning photovoltaic panels include manual cleaning, mechanical cleaning, and automated cleaning robots. Among these, manual cleaning is inefficient and costly, and it is difficult to meet the actual needs of large-scale photovoltaic power plants; mechanical cleaning equipment can improve cleaning efficiency.

[0004] For example, patent number 202411253042.6 discloses a mobile photovoltaic panel cleaning device, including a cleaning component, a support component, a flipping component, a first drive component, and a second drive component. The cleaning component includes a housing placed on the surface of the photovoltaic panel, and a sponge roller and a brush roller are symmetrically rotatably connected inside the housing. In this invention, the cleaning component is moved and cleaned on the surface of the photovoltaic panel by two drive components, and the rinsing is wiped clean with seawater, improving the cleaning effect.

[0005] Current technology is not comprehensive and has the following drawbacks: water washing requires a large amount of water during the cleaning process; dry cleaning, when cleaning the photovoltaic panels with brush rollers, the dust on the brush rollers will also adhere to the photovoltaic panels, resulting in dust still adhering to the photovoltaic panels after cleaning, and the photovoltaic panels are not cleaned thoroughly.

[0006] To solve one of the above problems, there is an urgent need for a remote-controlled cleaning machine for photovoltaic panels. Utility Model Content

[0007] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to make the rotating guide vanes not only clean the dust on the surface of the solar panel, but also gather the dust-laden air in the working area of ​​the dust collection hood towards the air outlet, and then discharge it away from the solar panel through the exhaust pipe connected to the air outlet, thus completing the cleaning of the solar panel. To this end, a photovoltaic panel remote control cleaning machine is provided.

[0008] The photovoltaic panel remote-controlled cleaning machine of this utility model includes a drone body with landing gear. It is characterized by further including an exhaust pipe with a rotating sleeve installed in the middle. The rotating sleeve is mounted on the drone body via an angle-adjusting mechanism. The angle-adjusting mechanism is equipped with a drive mechanism for rotating the exhaust pipe relative to the rotating sleeve. A cleaning disc is detachably mounted at the bottom of the exhaust pipe. The cleaning disc includes a dust collection hood with a downward-facing opening. The center of the dust collection hood has an air outlet connected to the exhaust pipe. The inner surface of the dust collection hood has multiple sets of guide vanes. These guide vanes extend from the air outlet in a centrifugal direction and are arranged in a vortex shape. An air inlet is formed between adjacent guide vanes, causing the incoming air to converge towards the center of the air outlet.

[0009] Using a remotely controlled drone as a carrier, the drive mechanism rotates the exhaust pipe, which in turn rotates the dust collection hood. By controlling the drone body, the dust collection hood is brought closer to the solar panel to be cleaned until the guide vanes contact the panel. The guide vanes rotate with the dust collection hood, sweeping away dust from the solar panel surface. Simultaneously, the rotating vanes also gather dust-laden air from the working area of ​​the dust collection hood towards the exhaust port, which is then discharged away from the solar panel through the exhaust pipe connected to the exhaust port, thus completing the cleaning of the solar panel. The exhaust pipe is designed to minimize the possibility of dust falling back onto the solar panel.

[0010] Preferably, the guide vane is made of rubber.

[0011] Preferably, the guide vane is made of rubber and has bristles installed on it.

[0012] Preferably, the guide vane is a brush, comprising multiple adjacent sets of bristles, and the bristles are fixedly connected to the dust collection hood.

[0013] Preferably, the dust collection hood has a disc-shaped structure and is provided with a plurality of guide vanes.

[0014] Preferably, the angle adjustment mechanism includes a first driver, a second driver, and horizontal connecting rods A and B symmetrically installed on both sides of the rotating sleeve. The other end of the horizontal connecting rod A is hinged to the telescopic end of the first driver 5.3, and the other end of the first driver is hinged to the landing gear on the left side of the UAV body. The other end of the horizontal connecting rod B is hinged to the telescopic end of the second driver, and the other end of the second driver is hinged to the landing gear on the right side of the UAV body. When the UAV body is flying horizontally, the exhaust pipe is in a vertical state when the lengths of the first driver and the second driver are the same. When the length of the first driver is greater than the length of the horizontal connecting rod B or the length of the first driver is less than the length of the horizontal connecting rod B, i.e., the two are not equal in length, the exhaust pipe can be changed from a vertical state to an inclined state. The cleaning disc after angle adjustment can be applied to photovoltaic panels with different inclination angles.

[0015] Preferably, both the first driver and the second driver are servo electric cylinders, electric push rods, or telescopic cylinders.

[0016] Preferably, the drive mechanism includes a drive motor mounted on a horizontal connecting rod A, a driving synchronous pulley mounted on the power output shaft of the drive motor, a driven synchronous pulley mounted on the lower part of the exhaust pipe, and a synchronous belt wound between the driving and driven synchronous pulleys. By using a drive motor as the power source, and transmitting power through the driven synchronous pulley, the synchronous belt, and the driving synchronous pulley, the exhaust pipe is driven to rotate.

[0017] Preferably, a bearing is provided between the exhaust pipe and the rotating sleeve to ensure relative rotation between the exhaust pipe and the rotating sleeve.

[0018] Preferably, the air outlet has an internal thread, and the bottom end of the exhaust pipe is provided with an external thread section that mates with the internal thread.

[0019] Preferably, a dust collection bag is installed on the landing gear of the drone body, the upper end of the exhaust pipe extends into the dust collection bag, the dust collection bag is a dust filter bag with mesh, and the connection between the dust filter bag and the exhaust pipe is a rotatable connection.

The guide vanes rotate with the dust collection hood, and the rotating guide vanes can clean the dust on the surface of the solar panel. At the same time, the rotating guide vanes can also gather the dust-laden air in the working area of ​​the dust collection hood towards the air outlet, and then discharge it away from the solar panel through the exhaust pipe connected to the air outlet, thus completing the cleaning of the solar panel.

The center of the dust collection hood 4.1 has an air outlet 4.2 connected to the exhaust pipe 2. The inner surface of the dust collection hood 4.1 has multiple sets of guide vanes 4.3. The multiple sets of guide vanes 4.3 extend from the air outlet 4.2 in a centrifugal direction and are arranged in a vortex shape. The air inlet is between adjacent guide vanes 4.3, so that the incoming air gathers towards the center of the air outlet 4.2.

[0035] The drive mechanism 6 drives the exhaust pipe 2 to rotate, which in turn drives the dust collection hood 4.1 to rotate. By controlling the main body 1 of the drone, the dust collection hood 4.1 is brought closer to the solar panel to be cleaned until the guide vanes 4.3 can contact the solar panel. The guide vanes 4.3 rotate with the dust collection hood 4.1, cleaning the dust on the surface of the solar panel. At the same time, the rotating guide vanes 4.3 also gather the dust-laden air in the working area of ​​the dust collection hood 4.1 towards the air outlet 4.2, and then discharge it away from the solar panel through the exhaust pipe 2 connected to the air outlet 4.2, thus completing the cleaning of the solar panel. The exhaust pipe 2 is designed to minimize the possibility of dust falling back onto the solar panel.

[0036] Example 2, as Figure 1-4As shown, the photovoltaic panel remote-controlled cleaning machine includes a drone body 1, which has a landing gear and an exhaust pipe 2.

The multiple sets of guide vanes 4.3 extend from the air outlet 4.2 in a centrifugal direction and are arranged in a vortex shape. The air inlet is between adjacent guide vanes 4.3, so that the incoming air gathers towards the center of the air outlet 4.2.

When the length of the first driver 5.3 is greater than the length of the horizontal connecting rod B5.2 or the length of the first driver 5.3 is less than the length of the horizontal connecting rod B5.2, i.e., the two are unequal in length, the exhaust pipe 2 can be converted from a vertical state to an inclined state. The cleaning disc 4 after angle adjustment can be applied to photovoltaic panels with different inclination angles.

[0041] Furthermore, both the first driver 5.3 and the second driver 5.4 are servo electric cylinders.

[0042] Furthermore, the drive mechanism 6 includes a drive motor 6.1 mounted on a horizontal connecting rod A5.1. A driving synchronous pulley is mounted on the power output shaft of the drive motor 6.1, and a driven synchronous pulley 6.2 is mounted on the lower part of the exhaust pipe 2.
