Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic cleaning, and in particular to a steel cable type photovoltaic panel cleaning device. Background Art

[0002] Application No. 2024109033752 is a photovoltaic panel cleaning device designed by the applicant. It uses a steel cable to drive a sponge to scrub the photovoltaic panels. During the use of the initial version, the following problems were found that could be improved:

[0003] 1. In some special areas and climates, photovoltaic panels may malfunction due to excessively high ambient temperatures. Regularly spraying water on the panels to cool them down can avoid this problem.

[0004] 2. The sponge needs to be cleaned after being used for a period of time. If a photovoltaic power station with a lot of pollutants is encountered, the sponge needs to be cleaned frequently, which results in low work efficiency and automation.

[0005] 3. The cleaning of fixed areas on the photovoltaic panels is not intelligent enough, and the cleaning cost is not further reduced. For example, as the sponge moves, some relatively clean photovoltaic panels that do not need to be cleaned will still be wiped by the sponge;

[0006] 4. The sponge cannot be used after being cleaned many times and needs to be replaced. If you encounter a photovoltaic power station with a lot of pollutants, you need to replace the sponge frequently, which reduces work efficiency.

[0007] 5. On highways, the main pollutants on cleaning sponges are dust, which is concentrated on both sides of the cleaning sponge's movement direction.

[0065] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0066] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely intended to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0067] Figures 1-6 This is the first specific embodiment of the present invention, which is an automatic cooling mechanism for a steel cable type photovoltaic cleaning device, and its specific implementation method is as follows:

[0068] When it is detected that the ambient temperature is too high, the cooling mechanism starts to operate at the same time, and the cooling device motor 10 drives the worm 12 to move. Mutual friction occurs between the worm 12 and the worm wheel 13, and the force in the direction of the motor is transmitted to the ball screw 8 through the transmission rod 15, and at the same time drives the nut 18 on the ball screw 8 to move. The nut 18 is connected to the slider seats 17 at both ends, driving the slider seats 17 at both ends to move on the linear guide rail 5. The water pipe 16 is connected between the slider seats 17 to spray water onto the cleaning sponge 3 to complete the whole action.

[0069] Figure 7-12 This is the second specific embodiment of the present invention, which is a sponge cleaning mechanism of a steel cable type photovoltaic cleaning device, and its specific implementation method is as follows:

[0070] When the cleaning equipment is finished, it returns to the parking space. If the system detects that the sponge needs to be cleaned, it sends a signal to the cleaning mechanism motor 34. The cleaning mechanism motor 34 drives the lead screw 27 to rotate through the cleaning mechanism coupling 35, thereby driving the nut seat 30 to perform linear motion. The cleaning robot arm 26 is connected and fixed to the nut seat 30 and the cleaning mechanism slider 31 by bolts, thereby performing linear motion along the slide rail 28. During the movement of the cleaning robot arm 26, the control system first sprays the cleaning agent through one of the cleaning nozzles 25. After the cleaning agent is sprayed, it controls the other nozzle in the cleaning nozzle 25 to discharge water to rinse and clean the contaminants on the sponge 3. After the cleaning work is completed, the cleaning robot arm 26 returns to its initial position and awaits the next work instruction.

[0071] Figure 13-17 This is the third specific embodiment of the present invention, which is a lifting mechanism of a steel cable type photovoltaic cleaning device, and its specific implementation method is as follows:

[0072] When the device recognizes that it needs to be lifted, the lifting device motor 37 drives the lifting device gear 40 to move, and friction movement occurs between the lifting device gear 40 and the lifting device rack 41. The lifting device rack 41 drives the connecting member 46 to move upward. At the same time, the two ends of the connecting member 46 are connected by a connecting rod 48, which transmits the lifting effect to the slider 47, driving the sliders 47 at both ends to perform synchronous lifting movements. The slider 47 itself is connected to the lifting device transmission rod 49, and the lifting device transmission rod 49 is connected to the cleaning sponge 3, thereby driving the entire cleaning sponge 3 to rise, completing the entire lifting action.

[0073] Figure 18-24This is the fourth specific embodiment of the present invention, which is a sponge automatic flipping and clamping mechanism of a steel cable type photovoltaic cleaning device, and its specific implementation method is as follows:

[0074] When the cleaning equipment is finished, it returns to its parking position. During this process, the clamping release device rack 55 engages with the gear in the sponge roller clamping release device housing 62 through the rack guide groove 58, thereby driving the cam 64 to rotate, releasing the sponge roller mounting shaft 63, allowing the sponge roller mounting shaft 63 to rotate. When the cleaning equipment reaches the leftmost side of the cleaning equipment parking rack 4, the clamping release device motor 56 drives the dial transmission rod 54 to rotate, thereby driving the dial 53 fixed to the sponge roller mounting shaft 63 to rotate, causing the sponge roller 51 to rotate, and the clean cleaning sponge of the next area is brought into the working area, awaiting the next cleaning task. When a cleaning task is assigned, the clamping release device rack 55 gradually withdraws from the rack guide groove 58. During this withdrawal process, it engages with the gear in the sponge roller clamping release device housing 62, thereby driving the cam 64 to rotate, re-clamping the sponge roller mounting shaft 63, so that the sponge roller 51 always uses the newly replaced cleaning sponge to clean the photovoltaic panel 1 during the cleaning operation.

[0075] Figure 25-28 This is the fifth specific embodiment of the present invention, which is a waterless cleaning mechanism for a steel cable type photovoltaic cleaning device, and its specific implementation method is as follows:

[0076] When the cleaning device is finished and returns to its parking position, if the system detects that the sponge needs to be cleaned, it sends a signal to the waterless cleaning device motor 70. The waterless cleaning device motor 70 drives the sponge cleaning mechanism roller scraper 66 to swing left and right via the synchronous belt 71 and synchronous pulley 73, thereby simulating a slapping action to clean the contaminants on the cleaning sponge 3. After the cleaning process is completed, the waterless cleaning device motor 70 stops and waits for the next work instruction.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
