Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic cleaning accessories, and particularly relates to an automatic flipping and clamping mechanism for a photovoltaic panel cleaning sponge. Background Art

[0002] With the annual installed capacity of photovoltaic power stations increasing year by year, dust on components has become one of the important factors affecting power generation, and component cleaning has received increasing attention. Currently, the cleaning methods of photovoltaic components can be roughly divided into three categories according to their automation levels: ① manual cleaning; ② semi-automatic cleaning method; ③ fully automatic cleaning method. Among them, the manual cleaning method mainly relies on manual labor, requires relatively intensive labor, and has low cleaning efficiency; the semi-automatic cleaning combines manual operation and mechanical equipment assistance; the fully automatic cleaning is mainly completed by intelligent cleaning robots, with relatively high operation and maintenance costs.

[0003] The cable-type cleaning equipment designed by the applicant mainly uses a sponge for scrubbing, with good cleaning effect and low cost. However, after using for a certain period of time, the sponge needs to be replaced. When encountering a photovoltaic power station with more pollutants, the sponge needs to be replaced frequently, resulting in low work efficiency.

[0004] Therefore, the present application designs an automatic flipping and clamping mechanism for a photovoltaic panel cleaning sponge to solve the above problems. Summary of the Invention

[0005] The present invention provides an automatic flipping and clamping mechanism for a photovoltaic panel cleaning sponge to make up for the deficiencies in the prior art.

[0006] An automatic flipping and clamping mechanism for a photovoltaic panel cleaning sponge, including a cleaning equipment bracket, characterized in that: The cleaning equipment bracket is slidably connected to one side of the photovoltaic panel. A sponge roller is installed at the center of the cleaning equipment bracket. The sponge roller is a multi-prismatic structure, and each surface is provided with a sponge. A sponge roller clamping and releasing device is installed at one end of the sponge roller. The sponge roller clamping and releasing device controls the flipping of the sponge roller to make the clean sponge face the photovoltaic panel.

[0007] Further, to better implement the present invention, the sponge roller clamping and releasing device includes a sponge roller clamping and releasing device box body connected to one end of the cleaning equipment bracket. A sponge roller clamping and releasing device upper cover plate is installed above the sponge roller clamping and releasing device box body through bolts. A sponge roller installation shaft of the sponge roller is rotatably connected in the sponge roller clamping and releasing device box body, and a clamping and releasing mechanism is arranged around the sponge roller installation shaft.

[0008] Furthermore, in order to better realize the present invention, the clamping and releasing mechanism includes a bearing mounting groove, four bearing chambers are opened on the bearing mounting groove, a central bearing chamber is connected to the sponge roller mounting shaft, and the other three bearing chambers surround the sponge roller mounting shaft. The other three bearing chambers are connected to a rotating rod through bearings, and a gear and a cam are installed on the rotating rod. The three cams clamp or release the sponge roller mounting shaft as the rotating rod rotates.

[0009] Furthermore, in order to better realize the present invention, the gear is detachable and engageable with a rack, a rack guide groove is opened on the box body of the sponge roller clamping and releasing device, and the rack is fixedly connected to the parking rack of the cleaning equipment on one side of the photovoltaic panel.

[0010] Furthermore, in order to better realize the present invention, the rack is installed on the motor and the rack mounting frame, and the motor is also installed on the motor and the rack mounting frame. The motor drives the transmission rod, and a dial fixedly connected to the sponge roller mounting shaft is provided on the outer side of the bearing mounting groove. A plurality of toggle columns are provided on the dial. The transmission rod is driven by the rotation of the motor to toggle the dial to control the sponge roller mounting shaft to rotate a certain angle.

[0011] Furthermore, in order to better realize the present invention, when the gear engages with the rack, that is, when the cleaning equipment bracket moves to the cleaning equipment parking rack, the rack drives the gear to rotate, drives the cam to rotate, releases the clamped sponge roller mounting shaft, and allows the motor to turn the dial to drive the sponge roller to rotate; when the gear disengages from the rack, that is, when the cleaning equipment bracket moves toward the photovoltaic panel, the three cams in the final meshing state of the gear and the rack clamp the sponge roller mounting shaft, so that the sponge roller will not rotate easily during cleaning.

[0012] The beneficial effects of the present invention are: The present invention arranges cleaning sponges in different areas of the drum. When the sponge in one area is contaminated after cleaning, when the cleaning device reaches the parking space, the cleaning sponge in the next area is automatically replaced by rotating the drum, so that the cleaning sponge in the next area enters the working state, ensuring the cleaning effect of the photovoltaic panel next time. If the sponges in all areas are contaminated, the sponge drum is replaced or the cleaning sponge on the sponge drum is cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents 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 efforts fall within the scope of protection of the present invention.

[0017] Figures 1-7 A specific embodiment of the present invention is a photovoltaic panel cleaning sponge automatic flipping and clamping mechanism. The cleaning equipment support 4 is slidably connected to one side of the photovoltaic panel 1. A sponge roller 5 is installed at the center of the cleaning equipment support 4. The sponge roller 5 is a multi-prismatic structure, and each surface is provided with a sponge. A sponge roller clamping and releasing device 6 is installed at one end of the sponge roller 5. The sponge roller clamping and releasing device 6 controls the flipping of the sponge roller 5 to make the clean sponge face the photovoltaic panel 1.

[0018] The sponge roller clamping and releasing device 6 includes a sponge roller clamping and releasing device box 16 connected to one end of the cleaning equipment bracket 4, a sponge roller clamping and releasing device upper cover 15 is installed above the sponge roller clamping and releasing device box 16 by bolts 14, a sponge roller mounting shaft 17 rotatably connected to the sponge roller 5 is provided in the sponge roller clamping and releasing device box 16, and a clamping and releasing mechanism is arranged around the sponge roller mounting shaft 17.

[0019] The clamping and releasing mechanism includes a bearing installation groove 13, and four bearing chambers are opened on the bearing installation groove 13. A central bearing chamber is connected to the sponge roller installation shaft 17, and the other three bearing chambers surround the sponge roller installation shaft 17. The other three bearing chambers are connected to a rotating rod through a bearing 19, and a gear and a cam 18 are installed on the rotating rod. The three cams 18 clamp or release the sponge roller installation shaft 17 as the rotating rod rotates. The gear is detachable and meshing with a rack 9, and a rack guide groove 12 is opened on the sponge roller clamping and releasing device box 16. The rack 9 is fixedly connected to the cleaning equipment parking rack 3 on one side of the photovoltaic panel 1.

[0020] The rack 9 is mounted on the motor and rack mounting frame 11, and the motor 10 is also mounted on the motor and rack mounting frame 11. The motor 10 drives the transmission rod 8. A dial 7 fixedly connected to the sponge roller mounting shaft 17 is arranged on the outer side of the bearing mounting groove 13. The dial 7 is provided with a plurality of toggle columns. The motor 10 rotates to drive the transmission rod 8 to toggle the dial 7 to control the sponge roller mounting shaft 17 to rotate a certain angle. When the gear is engaged with the rack 9, that is, when the cleaning device bracket 4 moves to the cleaning device parking rack 3, the rack 9 drives the gear to rotate, drives the cam 18 to rotate, releases the clamped sponge roller mounting shaft 17, and allows the motor 10 to toggle the dial 7 to drive the sponge roller 5 to rotate; when the gear is disengaged from the rack 9, that is, when the cleaning device bracket 4 moves toward the photovoltaic panel 1, the three cams 18 in the last meshing state of the gear and the rack 9 clamp the sponge roller mounting shaft 17, so that the sponge roller 5 will not rotate easily during cleaning.

[0021] The specific implementation of this embodiment is as follows: After the cleaning equipment finishes cleaning, the equipment returns to the parking space. During the process of returning to the parking space, the rack 9 meshes with the gear in the sponge roller clamping and releasing device box body 13 through the rack guide groove 12, thereby driving the cam 18 to rotate and releasing the sponge roller mounting shaft 17, enabling the mounting shaft to rotate. When the cleaning equipment reaches the leftmost side of the cleaning equipment parking rack 3, the motor 10 drives the transmission rod 8 to rotate, thereby driving the dial 7 fixed on the sponge roller mounting shaft 17 to rotate, causing the sponge roller 5 to rotate, and bringing the clean cleaning sponge in the next area into the working area to wait for the next cleaning task. When the cleaning task is issued, the rack 9 gradually exits the rack guide groove 12 and meshes with the gear in the sponge roller clamping and releasing device box body 13 during the exiting process, thereby driving the cam 18 to rotate and clamping the sponge roller mounting shaft 17 again, so that when the sponge roller 5 is performing the cleaning work, the photovoltaic panel 1 is always cleaned with the newly replaced clean sponge.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
