Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic panel cleaning equipment, and relates to a photovoltaic panel cleaner and a handheld photovoltaic panel cleaning device. Background Technology

[0002] Photovoltaic panels are a crucial component of photovoltaic (PV) power generation systems, and the cleanliness of their surfaces directly impacts power generation efficiency. Therefore, it is essential to use PV panel cleaning equipment to promptly remove dust, bird droppings, and other debris from the panels. Currently, the main equipment used for PV panel cleaning includes automated cleaning robots and handheld cleaning devices. Automated cleaning robots are primarily used for cleaning large areas of PV panels, but they are costly and heavy, making them inconvenient to move. Handheld cleaning devices are lightweight, portable, and less expensive, making them suitable for cleaning smaller areas of PV panels and allowing for focused cleaning of specific areas or corners. Existing handheld cleaning devices use disc-shaped brushes, which are not sufficiently thorough, especially for removing bird droppings and other debris, requiring multiple passes and resulting in low cleaning efficiency.

[0068] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0069] like Figures 1 to 34 As shown, the photovoltaic panel cleaner in this embodiment includes a support base 1, a front roller 21, a rear roller 22, a drive unit, and a transmission mechanism.

[0070] Side support frames 11 are provided at both the left and right ends of the support base 1.

[0071] The front roller 21 is located at the front end of the support base 1. Both ends of the front roller 21 are rotatably connected to the front ends of the side support frame 11 via bearings. Cleaning elements 23 are arranged along the circumference of the front roller 21. The rear roller 22 is located at the rear end of the support base 1. Both ends of the rear roller 22 are rotatably connected to the rear ends of the side support frame 11 via bearings. Cleaning elements 23 are arranged along the circumference of the rear roller 22. The cleaning elements 23 are configured as sheet-like bodies made of flexible material, with several sheet-like bodies arranged at equal intervals along the circumference; or, the cleaning elements 23 are configured as a row of bristles made of flexible material, with several rows of bristles arranged at equal intervals along the circumference.

[0072] The drive unit is mounted on the support base 1. The transmission mechanism connects the drive unit and the front roller 21, and the transmission mechanism also connects the drive unit and the rear roller 22. The drive unit drives the front roller 21 and the rear roller 22 to rotate relative to the support base 1 via the transmission mechanism.

[0073] The front roller 21 and the rear roller 22 rotate to continuously contact the cleaning component 23 with the photovoltaic panel surface. During cleaning, the cleaning component 23 on the front roller 21 first cleans the debris on the photovoltaic panel, and then, as the support base 1 moves forward, the cleaning component 23 on the rear roller 22 performs a second cleaning. Through two consecutive cleaning cycles, the photovoltaic panel achieves a high level of cleanliness and high cleaning efficiency.

[0074] In this embodiment, viewed from the left view of the photovoltaic panel cleaner, the front roller 21 rotates clockwise and the rear roller 22 rotates counterclockwise. This ensures that the photovoltaic panel cleaner is stably pressed against the surface of the photovoltaic panel, preventing the cleaner from bouncing or standing upright during cleaning, thus maintaining cleaning stability and improving cleaning efficiency.

[0075] The front end of the support base 1 is detachably bolted to a front roller cover 31, which covers the upper part of the front roller 21; the rear end of the support base 1 is detachably bolted to a rear roller cover 32, which covers the upper part of the rear roller 22.

[0076] The photovoltaic panel cleaner can perform both wet and dry cleaning of photovoltaic panels. When the front roller cover 31 and rear roller cover 32 are not removed, the photovoltaic panel cleaner performs wet cleaning of the photovoltaic panels. Water droplets generated during the cleaning process are blocked by the front roller cover 31 and rear roller cover 32, preventing water from splashing everywhere. Whether the front roller cover 31 and rear roller cover 32 are removed or not, the photovoltaic panel cleaner can perform dry cleaning. However, when the front roller cover 31 and rear roller cover 32 are removed, the photovoltaic panel cleaner performs dry cleaning of the photovoltaic panels, resulting in higher cleaning efficiency.

[0077] Side covers 33 are provided on the left and right ends of the support base 1. The side covers 33 cover the transmission mechanism to improve the safety of the photovoltaic panel cleaner and make the product more aesthetically pleasing.

[0078] In this embodiment, the driving unit is a motor 4. There are two motors 4. One motor 4 is connected to the front roller 21 via a transmission mechanism, and the other motor 4 is connected to the rear roller 22 via a transmission mechanism.

[0079] The drive unit (motor 4) is positioned between the front roller 21 and the rear roller 22, so that the center of gravity of the photovoltaic panel cleaner is in the middle position along the front-to-back direction. The transmission mechanism between motor 4 and the front roller 21 is located at the right end of the support base 1, and the transmission mechanism between motor 4 and the rear roller 22 is located at the left end of the support base 1, so that the center of gravity of the photovoltaic panel cleaner is in the middle position along the left-to-right direction. In this way, during the cleaning process of the photovoltaic panel cleaner, the force exerted on the surface of the photovoltaic panel by the front roller 21 and the rear roller 22 is balanced, thereby improving the cleanliness and efficiency of cleaning.

[0080] In this embodiment, the support base 1 is a cylindrical structure, and the motor 4 is located inside the cylindrical structure to make the product structure compact and facilitate modular manufacturing. Specifically, one motor 4 is arranged on each of the left and right sides inside the cylindrical structure.

[0081] The transmission mechanism includes a drive wheel 51, a driven wheel 52, and a transmission belt 53. The drive end of the drive unit is connected to the drive wheel 51, and the drive end of the drive unit drives the drive wheel 51 to rotate. One end of the front roller 21 and one end of the rear roller 22 are both connected to the driven wheel 52. The transmission belt 53 connects the drive wheel 51 and the driven wheel 52. Specifically, the output shaft of the motor 4 is connected to the drive wheel 51, and the rotation of the output shaft of the motor 4 drives the drive wheel 51 to rotate. The rotation of the drive wheel 51 drives the driven wheel 52 to rotate via the transmission belt 53, which in turn drives the front roller 21 and the rear roller 22 to rotate.

[0082] A water spray assembly is installed at the positions of the front roller 21 and / or the rear roller 22. In this embodiment, the water spray assembly is only installed at the position of the front roller 21. The photovoltaic panel cleaner performs a wet cleaning operation on the photovoltaic panel. The water spray assembly sprays water only at the position of the front roller 21. When the front roller 21 drives the cleaning component 23 to perform a first cleaning of the debris on the photovoltaic panel, the surface of the photovoltaic panel is moistened, making it easier to clean debris with strong adhesion (such as bird droppings) on the photovoltaic panel. Then, the cleaning component 23 on the rear roller 22 performs a second cleaning of the debris on the photovoltaic panel, cleaning the water droplets on the photovoltaic panel to reduce the amount of water droplets adhering to the photovoltaic panel and improve the cleanliness. It should be noted that if the amount of water droplets adhering to the photovoltaic panel is high after the wet cleaning operation, water stains are easily left on the photovoltaic panel, resulting in a lower cleanliness.

[0083] The water spray assembly includes an inlet pipe 61 and four outlet pipes 62 connected to the inlet pipe 61. The four outlet pipes 62 are arranged at equal intervals along the left and right directions. When the photovoltaic panel cleaner performs wet cleaning operations on the photovoltaic panels, water enters through the inlet pipe 61 and is sprayed through the outlet pipes 62 onto the front roller 21 and / or the rear roller 22, or onto the surface of the photovoltaic panel.

[0084] A drainage groove 12 is provided on the front end face and / or the rear end face of the support base 1. In this embodiment, drainage grooves 12 are provided on both the front end face and the rear end face of the support base 1. During the rotation of the front roller 21 and the rear roller 22, the cleaning component 23 will cause water droplets to be thrown towards the support base 1. After the drainage groove 12 is provided, the water droplets thrown towards the support base 1 will collect in the drainage groove 12. The height of the lower surface of the drainage groove 12 gradually decreases from one side of the support base 1 to the other side, so that the water in the drainage groove 12 can be discharged from one side of the support base 1. During the wet cleaning operation, the photovoltaic panel cleaner also cleans the photovoltaic panel row by row from one side to the other, so that the water flows to the uncleaned area of ​​the photovoltaic panel.

[0085] A handheld photovoltaic panel cleaning device is disclosed. This device includes the photovoltaic panel cleaner described above, with a handheld component 7 connected to a support base 1. The user moves the photovoltaic panel cleaner using the handheld component to clean the photovoltaic panels. The handheld component 7 includes a hinge base 71 and a connector 72. The hinge base 71 is fixedly connected to the support base 1, and the connector 72 is hinged to the hinge base 71. An extension rod can be connected to the connector 72 to facilitate cleaning by the user holding the extension rod.

[0086] The present invention has been described in detail above with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the photovoltaic panel cleaner of this invention. This photovoltaic panel cleaner, applied to a handheld photovoltaic panel cleaning device, first cleans the debris on the photovoltaic panel using the front roller 21 and its cleaning components 23. As the support base 1 moves forward, the rear roller 21 and its cleaning components 23 then perform a second cleaning of the debris on the photovoltaic panel. Through these two consecutive cleanings, the cleanliness of the photovoltaic panel is high, and the cleaning efficiency is also high. The photovoltaic panel cleaner has both wet and dry cleaning modes, which users can freely choose according to the actual surface conditions of the photovoltaic panel. The photovoltaic panel cleaner has a compact structure and adopts a modular design, making the product small in size, easy to carry, and easy to install and disassemble.

[0087] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model and should be protected by the present utility model.
