[0002] With the increasing shortage and pollution of energy, solar energy has gradually become the most ideal clean energy for the development of human society. However, the penetration rate of solar energy is not high and it has its own defects, one of which is the low conversion efficiency. For example, after a period of use, the surface of solar photovoltaic panels is easily contaminated with dust, which seriously affects the light penetration and reduces the efficiency of power conversion.

[0003] In the prior art, a general photovoltaic cleaning robot cleans photovoltaic panels by means of a rotating cleaning roller brush. Considering that wet cleaning easily leaves water stains on the surface of the photovoltaic panels, which easily refracts and reflects light, thereby affecting the luminous efficiency of the photovoltaic panels, a dry cleaning method is generally adopted. However, during the rotating cleaning of the photovoltaic panels, the dirt, dust or bird droppings on the photovoltaic panels are easily adhered to the cleaning roller brush, which easily causes secondary pollution to the subsequent photovoltaic panels, resulting in unclean cleaning and reducing the cleaning effect and luminous efficiency. Therefore, a photovoltaic cleaning robot with a quickly replaceable roller brush is proposed to solve the above problems. Utility Model Content

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.

[0031] Reference Figure 1 , Figure 2 , Figure 4 The utility model provides an embodiment: a photovoltaic cleaning robot with a quickly replaceable roller brush, comprising a main unit 1, a crawler chassis is arranged at the bottom of the main unit 1, which enhances the stability and passability in various terrains and facilitates the overall position of the mobile robot. It is a prior art. A lifting frame 2 capable of adjusting the height of a shell 3 is arranged on the left side of the main unit 1.

A shell 3 is arranged on the left side of the lifting frame 2, and a cleaning mechanism is arranged inside the shell 3. The cleaning mechanism comprises a centering rod 4 and a cleaning roller 12. A slot 5 matching the centering rod 4 is arranged on the inner wall of the shell 3. The centering rod 4 is plugged into the inner wall of the slot 5, and a control mechanism is arranged inside the centering rod 4.

[0032] Reference Figure 2-Figure 4 The left and right sides of the cleaning roller 12 are fixedly connected with mounting posts 13, and the inner wall of the shell 3 is provided with mounting grooves 14 that match the mounting posts 13. The mounting posts 13 are installed inside the mounting grooves 14, and the mounting posts 13 can rotate inside the mounting grooves 14. The mounting grooves 14 limit the rotation of the mounting posts 13 and the cleaning roller 12, thereby improving the rotation stability of the cleaning roller 12. An auxiliary mechanism is provided above the cleaning roller 12, and the auxiliary mechanism includes a stepping motor 15, a reciprocating screw 16, a cleaning plate 17, a gear 18 and a gear 2 19. The stepping motor 15 can accurately control the rotation angle of its output shaft, and is convenient for adjusting the rotation speed and rotation angle of its rotating shaft.

[0033] Reference Figure 5 The control mechanism includes a control rod 6 arranged in a horizontal state, and the control rod 6 is slidably installed on the inner wall of the centering rod 4. A pull rope 7 is fixedly connected to the right side of the control rod 6. The end of the pull rope 7 away from the control rod 6 is fixedly connected to a limit rod 8. The limit rod 8 is slidably installed on the inner wall of the centering rod 4. The sliding direction of the limit rod 8 is the radial direction of the centering rod 4. The limit rod 8 is elastically connected to the inner wall of the centering rod 4 through a spring 9. By setting the spring 9, an elastic force is applied to the limit rod 8 in a direction away from the center of the centering rod 4.

[0034] Reference Figure 4 , Figure 5 The inner wall of the slot 5 is provided with a limit groove 10 that matches the limit rod 8. The limit rod 8 is inserted into the inner wall of the limit groove 10. The number of limit rods 8 is set to be multiple, and multiple limit rods 8 are arranged in a ring-shaped and equiangular interval inside the centering rod 4. When the control rod 6 moves to the left, the pull rope 7 drives multiple limit rods 8 to move in the direction close to the center of the centering rod 4 at the same time, and the limit rod 8 is completely separated from the inside of the limit groove 10, so that the centering rod 4 can be pulled out to the left, and then the cleaning roller 12 can be conveniently and quickly taken out and replaced from the inside of the shell 3, so that roller brushes of different specifications and materials can be easily replaced. When the roller brush is worn or needs to be replaced to meet different cleaning needs, the replacement can be completed without a complicated disassembly process. The control mechanism also includes a limit ring 11, which is fixedly installed on the inner wall of the centering rod 4. The pull rope 7 passes through the inside of the limit ring 11, and the direction of the pull rope 7 is limited by setting the limit ring 11.

[0035] Reference Figure 1-Figure 3The stepper motor 15 is fixedly mounted on the left side of the housing 3, the right side of the output shaft of the stepper motor 15 is fixedly connected to the left side of the reciprocating screw 16, the reciprocating screw 16 is rotatably mounted on the inner wall of the housing 3, the cleaning plate 17 is slidably mounted on the surface of the reciprocating screw 16, and the cleaning plate 17 makes reciprocating linear motion in the axial direction of the reciprocating screw 16 when sliding, and the top of the cleaning plate 17 slides on the top of the inner wall of the housing 3 to improve the stability of the cleaning plate 17 during displacement, and the bottom of the cleaning plate 17 contacts the surface of the cleaning roller 12 to assist in cleaning the cleaning roller 12, thereby preventing the dirt and dust adhered to the surface of the cleaning roller 12 from causing secondary pollution to the photovoltaic panel, thereby improving the cleaning effect and luminous efficiency of the photovoltaic panel, and the gear 1 18 is fixedly mounted on the circumferential surface of the reciprocating screw 16, and the gear 2 19 is fixedly mounted on the circumferential surface of the mounting column 13, and the gear 1 18 and the gear 2 19 are meshed.

[0036] Working principle: When in use, place the mounting columns 13 at both ends of the cleaning roller 12 inside the mounting groove 14, then pull the control rod 6 on the left side of the centering rod 4, so that the control rod 6 pulls the limiting rod 8 through the pull rope 7 to completely enter the centering rod 4, and then insert the centering rod 4 to the right into the slot 5, so that the cleaning roller 12 is sleeved on the outside of the centering rod 4, and the gear 1 18 and the gear 2 19 are meshed, and then release the control rod 6, so that the limiting rod 8 is reset under the action of the spring 9 and enters the inside of the limiting groove 10, which fixes the centering rod 4. At the same time, the cleaning roller 12 can rotate outside the centering rod 4, which is convenient for cleaning the photovoltaic panel.

[0037] When it is necessary to clean the photovoltaic panel, the position is adjusted by adjusting the track at the bottom of the main machine 1, and the height of the shell 3 is adjusted by the lifting frame 2 to make the bottom of the cleaning roller 12 contact with the surface of the photovoltaic panel, and then the power of the stepper motor 15 is started. The stepper motor 15 drives the reciprocating screw 16 to rotate, and the rotation of the reciprocating screw 16 drives the gear 18 to rotate, and then the gear 2 19 rotates. The rotation of the gear 2 19 drives the mounting column 13 and the cleaning roller 12 to rotate, and the photovoltaic panel is cleaned. When the reciprocating screw 16 rotates, it will also drive the cleaning plate 17 to make reciprocating linear motion in the left and right directions, and then the dirt and dust adhered to the surface of the cleaning roller 12 is scraped off, so as to ensure the cleaning effect of the cleaning roller 12 on the photovoltaic panel.
