[0023] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] Combined with attachment Figure 1-3The cleaning machine 10 is a kind of cleaning machine for photovoltaic panels, including a photovoltaic panel cleaning machine 10. The photovoltaic panel cleaning machine 10 can perform cleaning work independently or be combined with other components to complete the cleaning work. The photovoltaic panel cleaning machine 10 includes a square tube beam 11 as a basic frame. The square tube beam 11 is a rectangular frame structure. Two symmetrically arranged roller brushes 12 are rotated in the square tube beam 11. The two roller brushes 12 rotate independently without affecting each other and are each controlled by an independent motor. Two spray pipes 13 are provided on the square tube beam 11 located outside the two roller brushes 12. Each spray pipe 13 is provided with a plurality of nozzles. The nozzles are evenly distributed on the spray pipe 13. The spray direction of the nozzles is toward the roller brush 12 on the inner side of each. The spray pipe 13 is also provided with related joints, hoses, hose clamps and other accessories. The spray pipe 13 is used to spray cleaning liquid to the photovoltaic panel to rinse the photovoltaic panel surface or loosen stubborn stains on the photovoltaic panel. The cleaning liquid is clean water or an aqueous solution containing a detergent. The spray pipe 13 can be connected to an external liquid supply pipeline for the cleaning liquid.

[0026] The lower sides of both sides of the square tube beam 11 are provided with several universal wheels 14 installed on the square tube beam 11. The universal wheels 12 are used to support the photovoltaic panel cleaning machine 10, so that the photovoltaic panel cleaning machine 10 can move on the photovoltaic panel surface, reducing the movement resistance of the photovoltaic panel cleaning machine 10. The universal wheels 14 do not have power and only have the function of assisting movement. The universal wheels 14 can be designed at any position on the lower side of the square tube beam 11 according to the length of the photovoltaic panel cleaning machine 10 and other requirements.

[0027] Sensors 15 are provided at the four top corners of the square tube beam 11. The sensors 15 protrude from the square tube beam 11. The sensors 15 are used to alarm when they reach the edge. When the photovoltaic panel cleaning machine 10 moves to the extreme position with the photovoltaic panel, the sensor 15 issues an alarm to prevent the photovoltaic panel cleaning machine 10 from falling. The sensor 15 is a photoelectric sensor. The protruding setting of the sensor 15 can detect the boundary of the photovoltaic panel before the photovoltaic panel cleaning machine 10.

[0028] A motor and electric regulator box 16 is provided on one side of the square tube beam 11. The motor and electric regulator box 16 is respectively provided with a motor 17 and an electric regulator 18 for controlling the motors of the two roller brushes 12. Each roller brush 12 has an independent set of motors 17 and electric regulators 18. The electric regulator 18 controls the motor 17 to make the roller brushes 16 on both sides rotate relative to each other. The rotation speed is independently controlled by the motor 17 and the electric regulator 18. It not only has the function of cleaning dirt on the surface of the photovoltaic panel and concentrating the dust between the two roller brushes 12 and discharging it along the axial direction, but also has the function of forming a speed difference by adjusting the rotation speeds of the two roller brushes 12 separately when using the machine, so as to realize the function of the machine moving in a unilateral direction.

[0029] Connectors 19 are provided on the outwardly facing sides of both sides of the square tube beam 11. The connectors 19 are used to connect other components, preferably to connect a pull rope for manual traction or to connect a tracked remote-controlled robot. The connectors are snap-fit ​​structures, which facilitate direct cooperation between the pull rope for manual traction or the tracked remote-controlled robot and the connectors.

[0030] The photovoltaic panel cleaning machine 10 is also provided with an electrical connector 20 , one end of which is used to connect to an external power source or device, such as a battery box 2 or a tracked remote-controlled robot, and the other end of the electrical connector 20 is connected to the motor 17 and the electric regulator 18 .

[0031] The photovoltaic panel cleaning machine 10 is provided with a battery box 21, which can provide power for the rotation of the roller brush 12. The battery box 21 is also very convenient and can be replaced quickly, so that the photovoltaic panel cleaning machine 10 can continue to work. The external power supply can be replaced multiple times during the cleaning service in exchange for longer battery life.

[0032] By controlling the rotational speeds of the two roller brushes 12 rotating in opposite directions, the two roller brushes 12 rotate at different speeds. In conjunction with the spray pipe 13, not only can the photovoltaic panels be cleaned, but the photovoltaic panel cleaning machine 10 can also be moved to the side where the rotational speed of the two roller brushes 12 is slower. In this way, the photovoltaic panel cleaning machine 10 completes the entire cleaning of the photovoltaic panel surface.

[0033] The square tube beam 11 is covered with an outer shell cover 23, and a handle 24 is provided on the outer shell cover. The outer shell cover 23 can prevent the components inside the photovoltaic panel cleaning machine 10 from being corroded by dust or water mist. The handle 24 is convenient for taking and placing the photovoltaic panel cleaning machine 10, and is easy to use.

[0034] Example 2

[0035] Combined with attachment Figure 4 The photovoltaic panel cleaning machine 10 can also work in conjunction with the unpowered wheel 31, so that the photovoltaic panel cleaning machine 10 can clean photovoltaic panels with a larger inclination angle.

[0036] The unpowered wheel 31 is arranged at the bottom of the square tube beam 11 located on one side of the motor and electric regulating box 16. The rotation direction of the unpowered wheel is parallel to the square tube beam 11, that is, the unpowered wheel 31 is in contact with the side of the photovoltaic panel and rotates on the side of the photovoltaic panel rather than the surface of the photovoltaic panel.

[0037] When equipped with the side non-powered wheels 31, the photovoltaic panel cleaning machine 10 can perform cleaning operations on photovoltaic panel assemblies with large inclination angles. By controlling the rotation speed of the two roller brushes 12 to form a speed difference, the machine can automatically move along the photovoltaic panel array without manual traction.

[0038] Example 3

[0039] Combined with attachment Figure 5The photovoltaic panel cleaning machine 10 can also be used in conjunction with a tracked remote-controlled robot 40. The tracked remote-controlled robot 40 is externally connected to the connector 19 and electrically connected through the electrical connector 15 to facilitate unified control.

[0040] After the photovoltaic panel cleaning machine 10 is connected to the crawler-type remote-controlled robot 40 , the crawler-type remote-controlled robot 40 can provide the active movement function, while the photovoltaic panel cleaning machine 10 focuses on cleaning the photovoltaic panels.

[0041] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
