Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic operation and maintenance and cleaning, and particularly relates to a cleaning mechanism for a photovoltaic tracking bracket. Background Technique

[0002] The photovoltaic tracking bracket is an important part of a solar photovoltaic power generation system, which is used to support, fix and dynamically adjust the angle of photovoltaic modules to capture solar energy to the maximum extent and improve the power generation efficiency. The photovoltaic tracking bracket is widely used in various photovoltaic power station scenarios, especially large-scale ground power stations, high-efficiency photovoltaic power stations and places with high requirements for energy output. In complex terrains and special climatic conditions, such as mountainous areas, deserts, coastal areas, etc., the photovoltaic tracking bracket also shows good adaptability and stability. Pollutants such as dust and bird droppings accumulated on the surface area of photovoltaic modules will significantly reduce their light transmittance, thereby affecting the power generation efficiency. Regularly cleaning the surface of photovoltaic modules and maintaining their cleanliness is an effective means to improve the power generation efficiency. The cleaning mechanism can automatically and intelligently complete this task to ensure that the photovoltaic modules are always in the best working state.

[0003] At present, the cleaning mechanisms of existing photovoltaic tracking brackets adopt a fixed design and cannot be flexibly adjusted according to the different widths and shapes of photovoltaic tracking brackets. This results in the need to prepare a variety of cleaning mechanisms with different sizes when dealing with different specifications of photovoltaic tracking brackets, which not only increases the use cost but also reduces the versatility and flexibility of the equipment. In practical applications, if the width of the photovoltaic tracking bracket changes slightly, it may cause the cleaning mechanism to not fit tightly, thereby affecting the cleaning effect. Moreover, the existing cleaning mechanisms often lack sufficient stability and smoothness during movement. Due to the lack of an effective buffering and supporting mechanism, the cleaning mechanism is prone to vibration and impact during movement, which may not only scratch or damage the surface of the photovoltaic panel but also accelerate the wear of the cleaning mechanism itself and shorten its service life. At the same time, the unstable movement state also affects the uniformity and efficiency of cleaning. Summary of the Utility Model

[0024] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings of the specification.

[0025] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model can also be implemented in other ways different from this description. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate from or mutually exclusive of other embodiments selectively.

[0027] Embodiment 1

[0028] Refer to the figure and see Figures 1-5 , which is the first embodiment of the present utility model. This embodiment provides a cleaning mechanism for a photovoltaic tracking bracket, including an installation frame 1. A transmission mechanism 2 is arranged inside the installation frame 1. A sweeper 3 is arranged at the bottom of the transmission mechanism 2. Installation frames 4 are arranged on both sides of the installation frame 1; further including:

[0029] Adjusting mechanisms 5 are arranged on both sides of the installation frame 4. Driving mechanisms 6 are arranged at the ends of the adjusting mechanisms 5. The driving mechanisms 6 are located on both sides of the photovoltaic tracking bracket. An auxiliary moving mechanism 7 is arranged at the bottom of the installation frame 4. The auxiliary moving mechanism 7 is located on the top of the photovoltaic panel.

[0030] Specifically, the transmission mechanism 2 includes a lead screw 201 rotatably installed inside the installation frame 1. One end of the lead screw 201 is fixedly connected to a transmission motor 202. Guide rails 203 are fixedly installed on the inner walls of both sides of the installation frame 1. A moving block 204 is slidably installed on the outer side of the guide rail 203. The sweeper 3 is fixedly installed at the bottom of the moving block 204. The moving block 204 is threadedly connected to the outer side of the lead screw 201.

[0031] Furthermore: The installation frame 1 serves as the main support structure of the cleaning mechanism, bearing the transmission mechanism 2, the sweeper 3, and other related components. The transmission mechanism 2 drives the sweeper 3 to clean on the surface of the photovoltaic panel, enabling the sweeper 3 to move smoothly along the guide rail 203 to ensure uniform cleaning effect. By driving the lead screw 201 to rotate through the transmission motor 202, and the lead screw 201 is threadedly connected to the moving block 204, the moving block 204 slides on the guide rail 203, thereby driving the sweeper 3 to perform linear movement. The sweeper 3 can effectively remove the dirt on the surface of the photovoltaic panel and improve the power generation efficiency of the photovoltaic panel. The installation frame 4 is used to connect the installation frame 1 and the adjusting mechanism 5, and at the same time support the auxiliary moving mechanism 7.

[0032] Specifically, the adjusting mechanism 5 includes electric cylinders 501 fixedly installed on both sides of the mounting frame 4. One end of the electric cylinder 501 is slidably installed with a push rod 502. The push rod 502 extends to the inside of the mounting frame 4 through the through holes on both sides of the mounting frame 4. The end of the push rod 502 is fixedly installed with a roller frame 503. The inner walls at both ends of the top of the mounting frame 4 are provided with sliding grooves 504. The top of the roller frame 503 is fixedly installed with sliders 505. The sliders 505 are slidably installed inside the sliding grooves 504. Both ends of one side of the roller frame 503 are fixedly installed with guide rods 506. The guide rods 506 are slidably installed in the guide holes on both sides of the mounting frame 4.

[0033] Furthermore: The adjusting mechanism 5 realizes the position adjustment of the driving mechanism 6 on the mounting frame 4 to adapt to photovoltaic tracking brackets of different widths, enabling the driving mechanism 6 to closely adhere to the side wall of the photovoltaic tracking bracket. By driving the push rod 502 to move with the electric cylinder 501, the push rod 502 drives the roller frame 503 to adjust its position under the guidance of the sliding groove 504 and the guide rod 506.

[0034] Specifically, the driving mechanism 6 includes a rotating shaft 601 rotatably installed inside the roller frame 503. The bottom end of the rotating shaft 601 is fixedly connected with a driving motor 602. The outside of the rotating shaft 601 is fixedly installed with a driving wheel 603. The driving wheel 603 is located inside the roller frame 503.

[0035] Furthermore: The driving mechanism 6 provides the power source for the movement of the cleaning mechanism. By driving the rotating shaft 601 to rotate with the driving motor 602, the rotating shaft 601 drives the driving wheel 603 to rotate, thereby pushing the cleaning mechanism to move on the photovoltaic tracking bracket.

[0036] Specifically, the auxiliary moving mechanism 7 includes a fixing plate 701 fixedly installed at the bottom. Both sides of the bottom of the fixing plate 701 are fixedly installed with sleeves 702. The bottom of the sleeve 702 is slidably installed with a telescopic rod 703. The bottom of the telescopic rod 703 is fixedly installed with an auxiliary wheel 704. A buffer spring 705 is sleeved outside the sleeve 702.

[0037] Furthermore: The auxiliary moving mechanism 7 improves the smoothness and stability of the movement of the cleaning mechanism. The cleaning mechanism is supported by the telescopic rod 703 and the auxiliary wheel 704, which play a role in auxiliary movement and buffering during movement. The buffer spring 705 is used to absorb the vibration during movement, effectively reducing the vibration and impact during movement, and protecting the cleaning mechanism and the photovoltaic panel.

[0038] Working principle:

[0039] In use, first start the cleaning mechanism. According to the width and shape of the photovoltaic tracking bracket, adjust the position of the driving mechanism 6 through the adjusting mechanism 5. The electric cylinder 501 drives the push rod 502 to move, and then drives the roller frame 503 to adjust its position under the guidance of the chute 504 and the guide rod 506, so that the driving mechanism 6 is closely attached to the side wall of the photovoltaic tracking bracket. The auxiliary wheel 704 of the auxiliary moving mechanism 7 contacts the top of the photovoltaic panel to provide stable support for the cleaning mechanism. Subsequently, the transmission motor 202 drives the lead screw 201 to rotate. The lead screw 201 is threadedly connected to the moving block 204, so that the moving block 204 slides on the guide rail 203. The moving block 204 drives the sweeper 3 to move smoothly along the guide rail 203 to clean the surface of the photovoltaic panel. At the same time, the driving motor 602 of the driving mechanism 6 drives the rotating shaft 601 to rotate, and the rotating shaft 601 drives the driving wheel 603 to rotate, pushing the cleaning mechanism to move on the photovoltaic tracking bracket. The telescopic rod 703 and the auxiliary wheel 704 of the auxiliary moving mechanism 7 play a role in assisting movement and buffering when the cleaning mechanism moves, and the buffer spring 705 absorbs the vibration during movement.

[0040] In summary: The design of the adjusting mechanism 5 allows adjustment according to the width and shape of the photovoltaic tracking bracket. The electric cylinder 501 drives the push rod 502 to move, and then drives the roller frame 503 to adjust its position under the guidance of the chute 504 and the guide rod 506, ensuring that the driving mechanism 6 can be closely attached to the side wall of the photovoltaic tracking bracket, realizing adaptive installation, improving the versatility and flexibility of the cleaning mechanism. The use of the auxiliary moving mechanism 7 improves the stability and smoothness of the cleaning mechanism during movement. The auxiliary wheel 704 contacts the top of the photovoltaic panel to provide stable support for the cleaning mechanism. At the same time, the buffer spring 705 can absorb the vibration and impact during movement, reducing the damage to the photovoltaic panel and the cleaning mechanism and extending the service life.
