Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic battery panels, and in particular to an automatic control system and a control method for cleaning a photovoltaic module. Background Art

[0003] The common methods for cleaning photovoltaic panels are to use track-type robots for fixed-point cleaning or cleaning carts for panel cleaning. Using track-type robots for cleaning requires laying special tracks on the photovoltaic panels and the robot itself is too heavy. Long-term use will cause the risk of cracking the photovoltaic panels. In addition, the cleaning brushes of track-type robots are usually too heavy to ensure the cleaning effect, which poses a safety hazard to the photovoltaic panels. When cleaning carts are used to clean the panels, a negative pressure device needs to be installed in the cart to ensure the cleaning effect. However, cleaning carts can usually only clean dust floating on the photovoltaic panels. For dust that has been attached to the photovoltaic panels for a long time, it often cannot achieve a good cleaning effect. At the same time, cleaning carts are often small in size and can only clean a small area at the same time. For larger photovoltaic power stations, there will be problems with low battery life and cleaning time efficiency.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0031] Preferably, a plurality of propellers 22 are provided on the side walls at both ends of the self-propelled track frame 11, a propeller controller reserved position 23 is provided on the top of the photovoltaic panel self-pressurized cleaning track 14, self-propelled track frame motor reserved positions 24 are provided on both sides of the self-propelled track frame 11, and self-pressurized track motor reserved positions 25 are provided on the side walls at both ends of the photovoltaic panel self-pressurized cleaning track 14.

[0032] According to another embodiment of the present invention, Fig.24 As shown, a control method for a photovoltaic module cleaning automatic control system is also provided, comprising the following steps: S1, placing a photovoltaic module cleaning automatic control system on the photovoltaic panel 10; S2, using the photovoltaic panel cleaning brush box 12 to rub and clean the surface of the photovoltaic panel 10; It should be explained that the initial photovoltaic panel cleaning brush box 12 is located at the top of the self-pressurized cleaning track 14. The side of the photovoltaic panel cleaning brush box 12 that contacts the photovoltaic cell panel 10 has a four-layer structure, namely, the photovoltaic panel cleaning brush box water spray hole 1, the rough wiping sponge 2, the oscillating water tank 3, and the cleaning sponge 4. The photovoltaic panel cleaning brush box 12 is connected to the outside with a water pipe 5, which can supply water to the photovoltaic panel cleaning brush box water spray hole 1. The spring 6 inside the cleaning brush box will deform with the extrusion, increasing the friction pressure of the bottom surface of the photovoltaic panel cleaning brush box 12 on the surface of the photovoltaic cell panel 10. The photovoltaic panel cleaning brush box water spray hole 1 is wetted by the water pipe 5 connected to the outside before cleaning, and the rough wiping sponge 2 wipes the surface of the photovoltaic cell panel 10 that has just been wetted, which can clean most of the attached dust, but there is still a small amount of stubborn deposited dust, so the ultrasonic oscillator generates ultrasonic waves in the oscillating water tank 3 to clean this part of the dust. The surface of the ultrasonic oscillator is covered with a PVA cleaning sponge full of water, and the oscillation effect is transmitted through the sponge medium. The cleaning sponge 4 is responsible for wiping the wiped sponge again to prevent water stains from remaining. By using different sponge structures to rub and clean the photovoltaic panel surface, it will not cause damage to the photovoltaic panel surface and can increase the friction cleaning effect. S3, by controlling the motor of the photovoltaic panel self-pressurizing cleaning track 14, the photovoltaic panel cleaning brush box 12 is moved cyclically in the self-pressurizing track upper track 15 and the self-pressurizing cleaning track lower track 16, and the friction pressure of the bottom end of the photovoltaic panel cleaning brush box 12 on the photovoltaic battery panel 10 is adjusted by using the interaction between the internal spring 6 of the cleaning brush box and the self-pressurizing clamping foot 13 to enhance the cleaning effect; It needs to be explained that the photovoltaic panel cleaning brush box 12 moves cyclically on the upper and lower tracks of the photovoltaic panel self-pressurized cleaning track 14 under the traction of the motors of the upper and lower parts of the track 15 on the self-pressurized track. When the photovoltaic panel cleaning brush box 12 moves up and down by friction, pressure is provided to the inside of the photovoltaic panel cleaning brush box 12. The spring 6 inside the cleaning brush box is squeezed by the dead weight of the photovoltaic panel self-pressurized cleaning track 14 and the self-pressurized clamping foot 13 to provide additional pressure to make the photovoltaic panel cleaning brush box 12 and the surface of the photovoltaic panel 10 tightly connected and rubbed. By increasing the pressure of the photovoltaic panel cleaning brush box 12 on the photovoltaic panel 10, the friction cleaning ability of the sponge at the bottom of the photovoltaic panel cleaning brush box 12 on the photovoltaic panel 10 is greatly improved.

[0033] S4, when the photovoltaic panel cleaning brush box 12 is rubbing and cleaning the surface of the photovoltaic panel 10, the positioning plate 20 on one side of the photovoltaic panel 10 is stretched by the motor of the self-propelled track frame 11 to move the positioning plate 20 on one side of the photovoltaic panel 10 to the middle pressure block 9 on one side of the next photovoltaic panel 10, and the positioning plate 20 is engaged with the middle pressure block 9 through the groove at the bottom of the positioning plate 20; It should be explained that when the photovoltaic panel cleaning brush box 12 rubs and cleans the surface of the photovoltaic panel 10, the right positioning plate 20 of the photovoltaic panel 10 will be stretched and moved to the middle pressure block 9 of the next photovoltaic panel 10 by the motors located on the left and right sides of the left and right self-propelled track frames 11, and the bottom grooves of the positioning plates 20 on both sides of the photovoltaic panel 10 are stuck and connected with the middle pressure block 9 to achieve the function of supporting the self-propelled track. The positioning plates 20 on both sides of the photovoltaic panel 10 cooperate with the middle pressure block 9 to achieve the function of positioning adjacent photovoltaic panels 10 when moving left and right.

[0034] S5, when the photovoltaic panel cleaning brush box 12 reaches the bottom of the photovoltaic battery panel 10, the photovoltaic panel cleaning brush box 12 is lifted from the lower track 16 of the self-pressurized cleaning track to the upper track 15 of the self-pressurized track by rotating the support frame 17 and the lifting plate 18. After the lifting is completed, the photovoltaic panel self-pressurized cleaning track 14 is gradually moved to the positioning plate 20 on the other side of the photovoltaic battery panel 10 by the motors on the side walls of the two ends of the photovoltaic panel self-pressurized cleaning track 14, ready for the next cleaning cycle; It should be explained that when the photovoltaic panel cleaning brush box 12 reaches the bottom of the photovoltaic panel 10, the photovoltaic panel cleaning brush box 12 needs to be lifted from the lower track 16 of the self-pressurized cleaning track to the upper track 15 of the self-pressurized track, so that the photovoltaic panel cleaning brush box 12 returns from the upper track 15 of the self-pressurized track to the top of the photovoltaic panel self-pressurized cleaning track 14. The photovoltaic panel cleaning brush box 12 is lifted to the upper track 15 of the self-pressurized track by rotating the support frame 17 so that the lifting plate 18 is supported. The self-pressurized clamping foot 13 rotates and lifts off the photovoltaic panel cleaning brush box 12, and then the photovoltaic panel self-pressurized cleaning track 14 is gradually moved to the right positioning plate 20 by the motors on the left and right sides of the self-propelled track frame 11, and the motor connected to the photovoltaic panel cleaning brush box 12 rotates to rearrange the photovoltaic panel cleaning brush box 12 to the top of the photovoltaic panel 10 through the self-pressurized track upper track 15 to prepare for the next cleaning, and the positioning plate 20 on the left side of the photovoltaic panel self-pressurized cleaning track 14 is also pulled by the motor to fit tightly to the photovoltaic panel self-pressurized cleaning track 14, and the self-propelled track frame 11 continues to be pulled by the motor to the adjacent panel surface, and the photovoltaic module cleaning automatic control system completes the cleaning of the surface of this photovoltaic panel 10, and prepares to clean the surfaces of the connected photovoltaic panels 10.

[0035] S6, using the propeller 22 to move the photovoltaic module cleaning automatic control system from the current photovoltaic cell panel 10 row to the next row, and manually controlling the propeller 22 to ensure that the photovoltaic module cleaning automatic control system is accurately aligned and placed on the surface of the photovoltaic cell panel 10; It needs to be explained that the present invention connects the STM32F103C8T6 single-chip microcomputer to the computer through the WIFI module, and controls the propeller 22 (i.e., the drone) through the STM32F103C8T6 single-chip microcomputer to move the photovoltaic module cleaning automatic control system from the current photovoltaic panel 10 rows to the next row of photovoltaic panels 10 that need to be cleaned, and manually controls the propeller 22 to ensure that the photovoltaic module cleaning automatic control system is accurately aligned, thereby enabling remote monitoring and control, making it convenient for users to grasp the operation status and cleaning effect of the device at any time.

[0036] It needs to be explained that when the photovoltaic panel moves up and down on the self-pressurized cleaning track 14, the photovoltaic component cleaning automatic control system can be transported from the air to the photovoltaic panel 10 by controlling the propeller 22 on the top of the photovoltaic component cleaning automatic control system, and the photovoltaic component cleaning automatic control system can be aligned and placed on the surface of another row of photovoltaic panels 10 by manually controlling the propeller 22, preparing to clean the surface of the next row of photovoltaic panels 10, so that the propeller 22 assists the photovoltaic component cleaning automatic control system to automatically change lines, thereby achieving the function of the photovoltaic component cleaning automatic control system to change lines and move up and down.

[0037] S7, repeating steps S4 to S6 until all photovoltaic panels 10 of the photovoltaic power station are cleaned and the cleaning process ends.

[0038] It needs to be explained that the photovoltaic module cleaning automatic control system requires the use of a motor drive, so a motor installation position and a motor wiring space need to be reserved inside the photovoltaic module cleaning automatic control system in order to drive the photovoltaic module cleaning automatic control system. All wires leading out of the motor and the water pipe 5 leading out of the photovoltaic panel cleaning brush box 12 are uniformly extended from the top of the photovoltaic module cleaning automatic control system.

[0039] To sum up, with the help of the above-mentioned technical scheme of the present invention, the invention adopts an intelligent control system, and connects the STM32F103C8T6 single-chip microcomputer to the computer through a WIFI module, which can realize remote monitoring and control, so that users can grasp the operation status and cleaning effect of the device at any time. The cleaning device is transported from the air by the propeller 22 to realize the line-changing movement function of the cleaning device, thereby greatly reducing manpower consumption. At the same time, the photovoltaic component cleaning automatic control system can be directly controlled by the STM32F103C8T6 single-chip microcomputer to move to the photovoltaic panel that needs to be cleaned, thereby greatly improving the time efficiency, and compared with the traditional water spray cleaning of the photovoltaic panel surface, it greatly saves water resources.
