[0044] In the embodiments of this utility model, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0045] like Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment provides a photovoltaic panel cleaning device that can reduce the difficulty of cleaning photovoltaic panels, improve inspection and cleaning efficiency, avoid operators climbing to heights, and reduce safety risks.

[0046] The photovoltaic panel cleaning equipment includes a drone 1, a rinsing unit 2, a camera unit 3, and a clamping unit 4. The drone 1 is configured to communicate with a remote control terminal; the rinsing unit 2 includes a water tank 21 and a nozzle 22, with the water tank 21 connected to the drone 1 and the nozzle 22 communicating with the water tank 21; the camera unit 3 is connected to the water tank 21 and / or the drone 1 and is configured to communicate with the remote control terminal, and is used to capture images of the location of the photovoltaic panel; the clamping unit 4 is connected to the water tank 21 and / or the drone 1 and is used to clamp foreign objects on the photovoltaic panel.

[0047] The aforementioned remote control terminal can be a remote controller, or a mobile terminal such as a mobile phone, tablet, or computer, which establishes a communication connection with the drone 1 by installing an app. The communication connection is not limited to WiFi or Bluetooth connections.

[0048] The aforementioned camera unit 3 can be connected to the water tank 21, the drone 1, or both the water tank 21 and the drone 1 simultaneously. It can be adapted to specific design requirements, as long as it can capture images of the photovoltaic panel.

[0049] The aforementioned clamping unit 4 can be connected to the water tank 21, the drone 1, or both the water tank 21 and the drone 1. It can be adapted to specific design requirements, as long as it can clamp foreign objects such as garbage on the photovoltaic panel.

[0050] The photovoltaic panel cleaning equipment provided in this application embodiment uses images captured by the camera unit 3 and a remote control terminal to move a drone 1 to the installation location of the photovoltaic panel. Water from the water tank 21 is sprayed out through the nozzle 22 to clean the photovoltaic panel, eliminating the need for operators to climb to heights and reducing the difficulty of cleaning the photovoltaic panel. Simultaneously, when foreign objects such as garbage are detected on the photovoltaic panel through the images captured by the camera unit 3, they can be picked up by the clamping unit 4, improving the cleanliness of the photovoltaic panel. This photovoltaic panel cleaning equipment can achieve cleaning on the ground, improving the efficiency of photovoltaic panel inspection and cleaning, avoiding the need for operators to climb to heights, and reducing safety risks.

[0051] Furthermore, the rinsing unit 2 also includes a water pump (not shown). The water pump's inlet is connected to the inside of the water tank 21, and its outlet is connected to the nozzle 22, for spraying water from the water tank 21 through the nozzle 22. Both the water pump and the clamping unit 4 can be directly connected to the remote control terminal, or connected to the remote control terminal via the control board of the UAV 1. By operating the remote control terminal, the water pump can be started or stopped, and the clamping action of the clamping unit 4 can be executed.

[0052] For example, the nozzle 22 is a high-pressure nozzle, which gives the sprayed water a sufficient force to improve the rinsing effect.

[0053] In this embodiment, see Figure 1 The photovoltaic panel cleaning equipment also includes a protective bracket 5, which is connected to the outer wall of the water tank 21. The photovoltaic panel cleaning equipment is supported on a support surface by the protective bracket 5. For example, the support surface is the ground, the surface of the photovoltaic panel, the roof plane, etc. When the drone 1 loses balance while flying above the photovoltaic panel and crashes, the photovoltaic panel cleaning equipment lands on the surface of the photovoltaic panel through the protective bracket 5 to prevent the propeller of the unbalanced drone 1 from damaging the photovoltaic panel.

[0054] Specifically, the protective bracket 5 includes a plurality of spaced-apart legs 51, one end of which is connected to the water tank 21. The plurality of legs 51 gradually extend in a direction away from the water tank 21 and tilt away from each other, thereby expanding the support area and making the protective bracket 5 support the photovoltaic panel cleaning equipment more stably.

[0055] For example, the protective bracket 5 includes three legs 51 arranged in a triangle, or four legs 51 located at the four corners of the water tank 21. Of course, the number and distribution of the legs 51 are not limited to the above-mentioned number and distribution, and can be designed as needed during the specific design stage. Moreover, the protective bracket 5 is not limited to a structure with multiple legs 51.

[0056] See Figure 1 The water tank 21 is equipped with protective brackets 5 on both the upper and lower sides. No matter whether the cleaning equipment falls forward or backward, it can land on the photovoltaic panel through the protective brackets 5, thus preventing the propellers of the drone 1 from damaging the photovoltaic panel.

[0057] In this embodiment, the four support legs 51 above the water tank 21 and the four support legs 51 below the water tank 21 are symmetrically arranged about the horizontal and vertical planes, which is beneficial to the overall force balance. Preferably, the extension area of ​​the support legs 51 can completely cover the drone 1, camera 31 and gripping unit 4, so as to prevent the drone 1, camera 31 and gripping unit 4 from colliding with the photovoltaic panel first when the cleaning equipment falls due to imbalance.

[0058] Furthermore, the support leg 51 of the protective bracket 5 is detachably connected to the water tank 21 and can be replaced after the support leg 51 is damaged by overload. For example, the support leg 51 can be connected to the outer wall of the water tank 21 by screws or clips.

[0059] Furthermore, a buffer pad is provided at the end of the support leg 51 of the protective bracket 5 away from the water tank 21. The protective bracket 5 can contact the photovoltaic panel through the buffer pad, avoiding dents in the photovoltaic panel due to hard contact between the support leg 51 and the photovoltaic panel. For example, the buffer pad is a rubber sleeve fitted onto the end of the support leg 51.

[0060] In this embodiment, see Figure 2 The nozzle 22 is provided in multiple ways, and the multiple nozzles 22 are distributed at least at the first end 211 and the second end 212 of the water tank 21. Along the direction away from the water tank 21, the nozzles 22 at the first end 211 and the nozzles 22 at the second end 212 extend in an inclined direction away from each other, which can expand the spray range of the rinsing unit 2 and realize large-area rinsing.

[0061] Furthermore, the first end 211 and the second end 212 are the two ends of the water tank 21 along the first direction, and both the first end 211 and the second end 212 are provided with multiple nozzles 22, and the multiple nozzles 22 are spaced apart along the second direction; wherein, the first direction and the second direction are arranged at an angle. Figure 2 In this diagram, the X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction. The X, Y, and Z directions are mutually perpendicular, meaning the first direction is perpendicular to the second direction. More specifically, the X and Y directions are the length and width directions of the water tank 21, respectively, and the Z direction is the height direction of the water tank 21, which is also the height direction of the drone 1. By setting multiple nozzles 22 arranged side-by-side along the Y direction at the first end 211 and the second end 212, the rinsing range can be further expanded, improving the rinsing and cleaning efficiency of the photovoltaic panels.

[0062] In this embodiment, the water tank 21 is located below the drone 1, the camera unit 3 and the clamping unit 4 are connected to the bottom wall of the water tank 21, and the nozzle 22 is connected to the lower end of the water tank 21. On the one hand, this can keep the overall center of gravity of the device in the middle position, which helps to maintain balance. On the other hand, it can prevent other components from interfering with the nozzle 22, the camera unit 3 and the clamping unit 4.

[0063] See Figure 3 The center of water tank 21 roughly coincides with the center of drone 1, which helps the overall equipment maintain balance.

[0064] For example, the clamping unit 4 includes a telescopic drive mechanism and a clamping assembly. The housing of the telescopic drive mechanism is connected to the water tank 21, and the output end of the telescopic drive mechanism is connected to the clamping assembly. The clamping assembly is used to move vertically under the drive of the telescopic drive mechanism and clamp foreign objects on the photovoltaic panel. That is, the clamping assembly can move vertically under the drive of the telescopic drive mechanism. When clamping foreign objects, it moves downward to a height lower than the end of the support leg 51 to avoid interference between the support leg 51 and the photovoltaic panel during the clamping process. When not clamping foreign objects, the telescopic drive mechanism drives the clamping assembly to move upward to a height higher than the end of the support leg 51 to prevent the clamping assembly from impacting and damaging the photovoltaic panel when the drone 1 falls due to imbalance.

[0065] The telescopic drive mechanism is exemplarily a pneumatic cylinder, hydraulic cylinder, or linear motor, and the clamping assembly is exemplarily a mechanical clamp or gripper cylinder. The telescopic drive mechanism and the clamping assembly can be directly connected to the remote control terminal, or connected to the remote control terminal via the control board of the UAV 1, to perform the action of picking up foreign objects.

[0066] Optionally, the photovoltaic panel cleaning equipment also includes an air blowing unit. The air blowing unit includes a blowing assembly and an air outlet. Both the blowing assembly and the air outlet are connected to the outer wall of the water tank 21. Before rinsing the photovoltaic panel, the blowing assembly can generate airflow, which is then blown onto the photovoltaic panel through the air outlet to clean it, thereby removing dust from the photovoltaic panel and preventing excessive dust from causing excessively dirty mud water during rinsing, which would result in incomplete cleaning of the photovoltaic panel.

[0067] For example, the blower assembly includes an air pump, a blower, a fan, etc., which is communicatively connected to a remote control terminal, and the air outlet is connected to the air inlet of the air outlet component, for example, through a flexible hose, so as to realize air outlet through the air outlet component. The air outlet component is exemplarily an air nozzle or an air knife.

[0068] Optionally, the outer wall of the water tank 21 is recessed with a protective groove (not shown in the figure), and the camera unit 3 is movably connected to the water tank 21, having a stored state within the protective groove and a working state where it is removed from the protective groove. When not in operation, the camera unit 3 can be stored in the protective groove, providing dustproof, waterproof, and collision-proof effects.

[0069] For example, see Figure 2 The camera unit 3 includes a camera 31 and a mounting bracket 32. The mounting bracket 32 ​​is rotatably connected to the outer wall of the water tank 21. By rotating the mounting bracket 32, the camera 31 can be rotated into or out of the protective groove.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
