Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning robot technology, specifically a drive mechanism for a photovoltaic panel cleaning robot. Background Technology

[0002] A photovoltaic panel cleaning robot is a device that uses robotics, artificial intelligence, and other technologies to efficiently and intelligently clean dust, fallen leaves, and other debris from the surface of photovoltaic panels through autonomous or remote control.

[0003] Existing photovoltaic panel cleaning robots clean photovoltaic panels by moving across continuously laid panels using cleaning rollers. However, due to the connecting frames between the panels and the slope between adjacent panels, the cleaning robot impacts the surface of the panels as it moves from one panel to another, potentially causing damage. Furthermore, the cleaning rollers in existing robots are linked to the drive mechanism controlling the robot's movement; therefore, the rotation direction of the cleaning rollers corresponds to the robot's movement direction, making it impossible to adjust the rollers' direction relative to the robot's movement. Utility Model Content

[0004] The purpose of this invention is to provide a drive mechanism for a photovoltaic panel cleaning robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drive mechanism for a photovoltaic panel cleaning robot, comprising two mounting plates, a connecting frame between the two mounting plates, a cleaning roller between the two mounting plates, a cleaning cotton strip and a sponge on the cleaning roller, first mounting blocks slidably mounted inside both ends of the mounting plates, a first transmission shaft rotatably mounted in the middle of the first mounting blocks, a roller fixedly mounted at one end of the first transmission shaft, second transmission rods symmetrically rotatably mounted in the middle of the mounting plates, the two second transmission rods rotating in opposite directions, a drive gear fixedly mounted at one end of the second transmission rod, and driven gears fixedly mounted at both ends of the cleaning roller, the driven gears meshing with the drive gears.

[0008] As a further preferred embodiment of this technical solution, a transmission gear is fixedly installed at the end of the second transmission rod away from the driving gear, and the two transmission gears are meshed together.

[0009] As a further preferred embodiment of this technical solution, pressure rollers are symmetrically mounted on one side of the mounting plate, and the pressure rollers are in extrusive contact with the surface of the transmission belt.

[0010] As a further preferred embodiment of this technical solution, the mounting plate is symmetrically and fixedly mounted with second limiting rods at both ends corresponding to the positions of the pressure rollers. A second mounting block is slidably mounted between the two second limiting rods. The pressure rollers are rotatably mounted in the middle of the second mounting block via a shaft pin. An adjusting spring is sleeved on the outer side of the top end of the second limiting rod.

[0012] This utility model provides a drive mechanism for a photovoltaic panel cleaning robot, which has the following advantages:

[0013] (1) When the cleaning robot moves from one photovoltaic panel to the next, the impact of the photovoltaic panel on the roller will cause the first mounting block connected to the roller to slide along the outside of the first limit rod. The buffer spring will buffer the force of the roller on the photovoltaic panel, thereby relieving the pressure of the roller on the photovoltaic panel and protecting the photovoltaic panel.

[0014] (2) This utility model drives the second transmission rod to rotate through the motor.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, a drive mechanism for a photovoltaic panel cleaning robot includes two mounting plates 1. A connecting frame is installed between the two mounting plates 1, and a cleaning roller 2 is installed between the two mounting plates 1. The cleaning roller 2 is equipped with cleaning cotton strips and sponges. By providing cleaning cotton strips and sponges on the cleaning roller 2, when adjusting the horizontal height at the central axis of the cleaning roller 2, the deformation and expansion of the cleaning cotton strips and sponges can constantly control the surface of the cleaning roller 2 to contact the surface of the photovoltaic panel, thereby achieving constant cleaning of the photovoltaic panel by the cleaning roller 2. Both ends of the mounting plate 1 have internal sliding surfaces. A first mounting block 3 is installed, and a first drive shaft 4 is rotatably mounted in the middle of the first mounting block 3. A roller 5 is fixedly mounted at one end of the first drive shaft 4. A second drive rod 6 is symmetrically rotatably mounted in the middle of the mounting plate 1, with the two second drive rods 6 rotating in opposite directions. A drive gear 7 is fixedly mounted at one end of each second drive rod 6. Driven gears 8 are fixedly mounted at both ends of the cleaning roller 2. The driven gears 8 mesh with the drive gears 7. By driving the driven gears 8 on the cleaning roller 2 to mesh with the drive gears 7 on the second drive rods 6, the cleaning roller 2 will rotate. The cleaning roller 2 constantly presses against the surface of the photovoltaic panel to clean it. The mounting plate 1 has two symmetrically fixed first limiting rods 9 at both ends. The first mounting block 3 is slidably mounted between the two first limiting rods 9. A buffer spring 10 is sleeved on the outer side of each end of the first limiting rod 9. One end of the buffer spring 10 is fixedly connected to the first mounting block 3, and the other end is fixedly connected to the mounting plate 1. When the cleaning robot moves from one photovoltaic panel to the next, the impact of the photovoltaic panel on the roller 5 will cause the first mounting block 3 connected to the roller 5 to move along the first limiting rod. The outer side of the position rod 9 slides, and the force of the buffer roller 5 acting on the photovoltaic panel is relieved by the buffer spring 10, which is used to protect the photovoltaic panel. By driving the cleaning roller 2 to rise or fall synchronously, the driven gear 8 on the cleaning roller 2 can be changed to mesh with one of the driving gears 7 on the two second transmission rods 6, which can drive the adjustment of the rotation direction of the cleaning roller 2. By setting cleaning cotton strips and sponges on the cleaning roller 2, the deformation and expansion of the cleaning cotton strips and sponges can control the surface of the cleaning roller 2 to contact the surface of the photovoltaic panel at all times, so as to achieve the constant cleaning of the photovoltaic panel by the cleaning roller 2.

[0022] like Figures 1 to 4 As shown, a first transmission wheel 11 is fixedly installed at one end of one of the second transmission rods 6, a second transmission wheel 12 is fixedly installed at the end of the first transmission shaft 4 away from the roller 5, a transmission belt 13 is installed between the two second transmission wheels 12 and the first transmission wheel 11, a motor 14 is fixedly installed on one side of the mounting plate 1, and the output end of the motor 14 is fixedly connected to one end of the second transmission rod 6 on which the first transmission wheel 11 is installed.

[0023] The motor 14 drives the second transmission rod 6 to rotate, which in turn drives the first transmission wheel 11 to rotate. The transmission belt 13 drives the two second transmission wheels 12 and the first transmission wheel 11 to rotate, which in turn drives the roller 5 mounted on the first transmission shaft 4 to rotate, thus controlling the cleaning robot to move on the photovoltaic panel.

[0024] like Figures 1 to 4 As shown, a transmission gear 15 is fixedly installed at the end of the second transmission rod 6 away from the driving gear 7, and the two transmission gears 15 are meshed together.

[0025] The motor 14 drives the second transmission rod 6 to rotate. The meshing between the two transmission gears 15 at the ends of the two second transmission rods 6 will cause the two second transmission rods 6 to rotate in opposite directions, which will also cause the drive gear 7 at the ends of the second transmission rods 6 to rotate in opposite directions.

[0026] like Figures 1 to 4 As shown, pressure rollers 16 are symmetrically installed on one side of the mounting plate 1. The pressure rollers 16 are in contact with the surface of the transmission belt 13. Second limiting rods 17 are symmetrically fixedly installed at both ends of the mounting plate 1, corresponding to the positions of the pressure rollers 16. A second mounting block 18 is slidably installed between the two second limiting rods 17. The pressure rollers 16 are rotatably installed in the middle of the second mounting block 18 through a shaft pin. An adjusting spring 19 is sleeved on the outer side of the top end of the second limiting rod 17. One end of the adjusting spring 19 is fixedly connected to the second mounting block 18, and the other end of the adjusting spring 19 is fixedly connected to the mounting plate 1.

[0027] When the first mounting block 3 slides along the outside of the first limiting rod 9, the pressure roller 16 will constantly press down on the transmission belt 13 under the pressure of the adjusting spring 19 on the second mounting block 18. This is to keep the transmission belt 13 taut at all times and to control the transmission belt 13 to transmit stably between the two second transmission rollers 12 and the first transmission roller 11.

[0028] like Figures 1 to 4 As shown, a lifting block 20 is slidably installed in the middle of the mounting plate 1, and a cleaning roller 2 is rotatably installed in the middle of the lifting block 20. An electric push rod 21 is symmetrically fixedly installed on the top of the mounting plate 1, and the moving end of the electric push rod 21 passes through the mounting plate 1 and is fixedly connected to the top of the lifting block 20.

[0029] The electric push rod 21 drives the lifting block 20 to rise or fall, which in turn drives the cleaning roller 2 installed on the lifting block 20 to rise or fall synchronously, thus changing the height of the cleaning roller 2.

[0030] This utility model provides a drive mechanism for a photovoltaic panel cleaning robot, the specific working principle of which is as follows:

[0031] When the device is in use, the motor 14 drives the second transmission rod 6 to rotate, which in turn drives the first transmission wheel 11 to rotate. The transmission belt 13 drives the two second transmission wheels 12 and the first transmission wheel 11 to rotate, which in turn drives the roller 5 mounted on the first transmission shaft 4 to rotate. This allows the cleaning robot to move on the photovoltaic panel. The cleaning roller 2 will be in constant contact with the surface of the photovoltaic panel. When the motor 14 drives the second transmission rod 6 to rotate, the driven gear 8 on the cleaning roller 2 will mesh with the driving gear 7 on the second transmission rod 6, which will drive the cleaning roller 2 to rotate, thus cleaning the photovoltaic panel.

[0032] As the cleaning robot moves from one photovoltaic panel to the next, the impact of the photovoltaic panel on the roller 5 will cause the first mounting block 3 connected to the roller 5 to slide along the outside of the first limit rod 9. The buffer spring 10 will buffer the force of the roller 5 on the photovoltaic panel, thereby relieving the pressure of the roller 5 on the photovoltaic panel and protecting the photovoltaic panel.

[0033] When the first mounting block 3 slides along the outside of the first limiting rod 9, the pressure roller 16 will constantly press down on the transmission belt 13 under the pressure of the adjusting spring 19 on the second mounting block 18, so as to keep the transmission belt 13 in a taut state at all times and to control the transmission belt 13 to stably transmit between the two second transmission rollers 12 and the first transmission roller 11 at all times.

[0034] When adjusting the moving direction of the cleaning robot and the rotation direction of the cleaning roller 2, the motor 14 drives the second transmission rod 6 to rotate. The meshing between the two transmission gears 15 at the ends of the two second transmission rods 6 will cause the two second transmission rods 6 to rotate in opposite directions, which will also cause the drive gears 7 at the ends of the second transmission rods 6 to rotate in opposite directions. The electric push rod 21 drives the lifting block 20 to rise or fall, which can drive the cleaning roller 2 installed on the lifting block 20 to rise or fall synchronously. The driven gear 8 on the cleaning roller 2 can be changed to mesh with one of the drive gears 7 on the two second transmission rods 6, which can adjust the rotation direction of the cleaning roller 2. By setting cleaning cotton strips and sponges on the cleaning roller 2, the deformation and expansion of the cleaning cotton strips and sponges can control the surface of the cleaning roller 2 to contact the surface of the photovoltaic panel at all times, so as to achieve the constant cleaning of the photovoltaic panel by the cleaning roller 2.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
