DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 A photovoltaic panel cleaning robot includes a remote-controlled robot car 1 that moves along the upper surface of the photovoltaic panel. A dust removal component is installed above the car body of the remote-controlled robot car 1. A vacuum device is detachably connected to the dust removal component. Negative pressure is generated by starting the vacuum device to remove dust attached to the surface of the photovoltaic panel on the path of the remote-controlled robot car 1.

[0024] A dust raising component is installed between the dust removal component and the front of the remote-controlled robot car 1. Since the dust raising component is installed at the front end of the remote-controlled robot car 1 in the forward direction, it can first raise the dust attached to the surface of the photovoltaic panel, making it convenient for subsequent dust removal work.

[0025] The dust removal component includes a dust storage box 2 fixedly connected to the car body panel of the remote-controlled robot car 1, and a dust suction pipe 3 with the top end connected to the inner cavity of the dust storage box 2 is passed through the car body panel below the dust storage box 2, so that the raised dust can be sucked into the dust storage box 2 through the dust suction pipe 3 and stored inside.

[0026] The air extraction device includes a negative pressure pipe 4 connected to the side of the dust storage box 2 away from the dust generating component, a first motor 5 whose output end is fixedly connected to the fan blade 6 is installed in the inner cavity of the negative pressure pipe 4, and a dust filter device is fixedly connected in the inner cavity of the connection end of the negative pressure pipe 4 and the dust storage box 2. When in use, the first motor 5 can be started, and the fan blade 6 can be driven by the first motor 5 to rotate at a high speed to discharge the air inside the dust storage box 2, so that negative pressure is generated inside the dust storage box 2, and the dust and air raised are sucked into the dust storage box 2 by the negative pressure.

[0027] For details, please refer to Figure 1 The bottom end of the dust suction pipe 3 is flush with the height of the lower surface of the compartment plate of the remote-controlled robot car 1, and the top end of the dust suction pipe 3 penetrates the bottom wall of the dust storage box 2 and extends upward to the inner cavity of the dust storage box 2. The bottom end of the dust suction pipe 3 is flush with the height of the lower surface of the compartment plate of the remote-controlled robot car 1 to prevent the bottom end of the dust suction pipe 3 from causing interference when the remote-controlled robot car 1 moves. The top end of the dust suction pipe 3 penetrates the bottom wall of the dust storage box 2 and extends upward to the inner cavity of the dust storage box 2, which can minimize the dust inside the dust storage box 2 from falling directly through the dust suction pipe 3 when the first motor 5 is turned off.

[0028] For details, please refer to Figure 3 The end of the negative pressure pipe 4 close to the dust storage box 2 is fixedly connected with a screw ring 8, and the outer wall of the dust storage box 2 extends outward to form a tubular joint, and the negative pressure pipe 4 is screwed to the tubular joint through the screw ring 8. The screw ring 8 is provided for installing the negative pressure pipe 4, and the screw connection method is adopted, which is not only stable, but also convenient for users to install and remove the negative pressure pipe 4.

[0029] For details, please refer to Figure 3 A plurality of symmetrically distributed connecting rods 7 are provided around the first motor 5, and the two ends of the connecting rods 7 are respectively fixedly connected to the housing of the first motor 5 and the inner wall of the negative pressure tube 4. The connecting rods 7 are provided to fix the first motor 5, and at the same time, a channel for air discharge is formed between the periphery of the first motor 5 and the inner wall of the negative pressure tube 4.

[0030] For details, please refer to Figure 1The dust filter device includes a filter cloth 9 embedded in the inner cavity of the negative pressure pipe 4, and the periphery of the filter cloth 9 is bonded to the inner wall of the negative pressure pipe 4. The filter cloth 9 is provided to filter the air discharged from the negative pressure pipe 4, and to prevent dust from being discharged again through the negative pressure pipe 4 and falling onto the photovoltaic panel, thereby affecting the cleaning effect of the photovoltaic panel.

[0031] For details, please refer to Figure 1 The dust removal component includes a protection box 10 fixedly connected to the car body board of the remote control robot car 1, a second motor 11 is fixedly connected to the bottom wall of the inner cavity of the protection box 10, and the output end of the second motor 11 is connected to a brush plate 14 whose bristles fit the photovoltaic panel through an elastic connector. When in use, the user starts the second motor 11, and drives the brush plate 14 to brush along the outer surface of the photovoltaic panel through the elastic connector to lift the dust attached to the upper surface of the photovoltaic panel.

[0032] Specifically, refer to Figure 1 The elastic connecting member includes a transmission tube 12 fixedly connected to the output end of the second motor 11, one end of the transmission tube 12 away from the second motor 11 penetrates the carriage plate of the remote-controlled robot car 1 and is rotatably connected to the carriage plate of the remote-controlled robot car 1, the bottom end of the transmission tube 12 is slidably connected with a transmission rod 13, and the brush plate 14 is installed on one end of the transmission rod 13 located outside the transmission tube 12, and the bottom end of the transmission tube 12 is sleeved with a spring 15 fixedly connected to the transmission tube 12, and the other end of the spring 15 is fixedly connected to the upper surface of the brush plate 14. The transmission tube 12 and the transmission rod 13 can only slide relative to each other in the vertical direction but cannot rotate relative to each other, which does not affect the second motor 11 driving the brush plate 14 to rotate, and the spring 15 in a compressed state is set to abut against the upper surface of the brush plate 14, and the brush plate 14 is pushed downward by the elastic force of the spring 15 itself, so that the bristles of the brush plate 14 are always in contact with the upper surface of the photovoltaic panel, which is convenient for the brush plate 14 to perform dust removal work.

[0033] Working principle: When in use, the user first places the remote-controlled robot car 1 on the photovoltaic panel, and turns on the first motor 5 and the second motor 11 at the same time, and then remotely controls the remote-controlled robot car 1 to move along the surface of the photovoltaic panel through the remote control. At this time, the second motor 11 first drives the brush plate 14 to rotate, and the dust attached to the photovoltaic panel is lifted up by the bristles. As the remote-controlled robot car 1 continues to move and drives the dust suction tube 3 to move to the position where the dust is lifted, the first motor 5 drives the fan blades 6 to rotate at high speed to discharge the air filtered by the filter cloth 9, so that negative pressure is generated inside the dust storage box 2, and under the action of the negative pressure, the lifted dust is sucked into the dust storage box 2 for storage, thereby avoiding the problem that the existing cleaning equipment lacks dust collection, and the dust lifted by the brush is easy to fall on the photovoltaic panel again, resulting in poor cleaning effect of the cleaning equipment.
