Description

Technical Field

[0001] This application relates to the technical field of cleaning the glass surface of photovoltaic panels, and particularly to a cleaning device for the glass surface of photovoltaic panels. Background Art

[0002] Under the background of the global active promotion of energy transformation and the vigorous development of renewable energy, the photovoltaic industry has witnessed rapid development due to its clean and sustainable characteristics. Photovoltaic panels, as the core components of photovoltaic power generation systems, are widely used. Usually, photovoltaic panels are manufactured using factory assembly lines and then transferred for storage or packaging. When the photovoltaic panels are transferred, dirt in the workshop, such as dust particles, may inadvertently adhere to the glass surface. A large amount of dust may accumulate on the glass surface of the photovoltaic panels. For photovoltaic panels, dust will seriously interfere with the light propagation path. When light shines on the dusty glass surface of the photovoltaic panel, most of the light will be scattered in all directions by the dust, and only a small part can penetrate and reach the semiconductor material inside the photovoltaic panel, thereby exciting electrons to generate electricity. The amount of dust on the surface of the photovoltaic panel will affect the performance of the photovoltaic panel, which will have an impact on the power generation efficiency of the photovoltaic power generation system. Summary of the Invention

The material clamping mechanism is configured to be able to clamp the flexible cleaning sheet on the driving mechanism to tear off the flexible cleaning sheet, and the material storage mechanism is configured to be able to store multiple flexible cleaning sheets for the adhesive member to pick up.

[0005] By adopting the above technical solution, after the photovoltaic panel is carried by the carrying device, the cleaning device is driven and cooperated with the driving and positioning device to clean the glass surface of the photovoltaic panel in all directions. The specific cleaning actions are as follows: Drive the driving mechanism to drive the bonding part to bond the flexible cleaning sheet on the material storage mechanism, then drive the driving mechanism to drive the flexible cleaning sheet to softly press on the glass surface of the photovoltaic panel and drive the flexible cleaning sheet to rotate to clean the dirt. After that, drive the driving mechanism again to drive the flexible cleaning sheet to move to one side of the material clamping mechanism, and drive the material clamping mechanism to clamp the flexible cleaning sheet. At this time, the flexible cleaning sheet can be torn off under the cooperation of driving the driving mechanism. Then, repeat the above actions to continuously clean the flowing photovoltaic panel. The above actions can facilitate the cleaning of the dust on the glass surface of the photovoltaic panel.

[0006] Preferably, the driving mechanism includes a gear-rack transmission assembly installed on the frame. The gear-rack transmission assembly is connected with a first frame body.

[0021] By adopting the above technical solution, based on the strip groove, the connection position between the fastener and the plate body can be changed, thereby changing the position of the limiting rod. This enables the storage area to store flexible cleaning sheets of different sizes and densities. By setting multiple storage mechanisms, multiple different types of flexible cleaning sheets can be stored. Then, based on the vision detection component, the position and size of the dirt on the photovoltaic panel can be detected. Based on the size of the dirt, flexible cleaning sheets of different densities and types can be selected to effectively clean the dirt.

[0022] Preferably, two lateral adjustment driving members of the adjustment device are arranged on the frame, and the two lateral adjustment driving members are symmetrically arranged; each lateral adjustment driving member is equipped with a pressing member, and the two pressing members are respectively located on both sides of the photovoltaic panel.

[0044] Referring to Figure 6 and Figure 7 , the storage rack 462 includes a plate body 4622 provided on the mounting bracket 461. A plurality of limiting rods 4623 are provided at the upper end of the plate body 4622. The storage area 4621 is formed between the plurality of limiting rods 4623. In this embodiment, the number of the limiting rods 4623 is four. A through push hole 46221 for the push plate 464 to pass through is formed on the plate body 4622. The plate body 4622 is slidably connected to the mounting bracket 461. The plate body 4622 can be slid out of the mounting bracket 461. An iron sheet 4624 is also installed on the plate body 4622.

[0045] The plate body 4622 can be directly forced to move the plate body 4622 downward and then loaded. After that, moving the plate body 4622 back to its original position so that the magnetic attraction member 4625 attracts the iron sheet 4624 is enough.

[0046] Referring to Figure 6 andFigure 7 On each limiting rod 4623, a connecting hole 46231 is formed. Corresponding to each limiting rod 4623 on the plate body 4622, a strip-shaped groove 46222 is formed. The strip-shaped groove 46222 extends outward from the central position of the plate body 4622. Each connecting hole 46231 and the corresponding strip-shaped groove 46222 are jointly connected by a fastening member, and the fastening member can be a screw.

In addition, to meet the use requirements, a plurality of material storage mechanisms 46 are provided to simultaneously store multiple types of flexible cleaning sheets 44 for picking.

[0047] Based on the fact that the strip-shaped groove 46222 can change the connection position between the fastening member and the plate body 4622, thereby changing the position of the limiting rod 4623, this enables the material storage area 4621 to become larger or smaller, and the material storage area 4621 can store different types of flexible cleaning sheets 44, such as flexible cleaning sheets 44 of different sizes or different densities.

[0048] Based on the position and size of the dirt detected on the photovoltaic panel by the visual inspection member, and based on the size of the dirt, the driving mechanism 41 is driven to drive the bonding member 43 to move to the flexible cleaning sheet 44 of the required type for picking, and based on the type of dirt, such as dust or glue, the driving member 415 can flexibly adjust the output rotation to achieve the purpose of effectively cleaning the dirt.

At the same time, the driving gear-rack transmission assembly drives the flexible cleaning sheet 44 to move along a linear path to clean the glass surface of the photovoltaic panel, and at the same time, the suction cylinder 422 is used to suck in the cover 421 to suck out the dirt; in addition, during the cleaning process, the two lateral position adjustment driving members 31 are flexibly and simultaneously driven to drive the two pressing members 32 to move left and right synchronously to adjust the position of the photovoltaic panel and then change the cleaning position; After the cleaning is completed, the driving gear-rack transmission assembly 411 and the vertical driving member 413 drive the flexible cleaning sheet 44 to move between the two vertical clamping members 452. The driving transverse clamping member 451 drives the two vertical clamping members 452 to move towards each other and drives the two vertical driving members 413 to clamp the flexible cleaning sheet 44 to complete the tearing of the flexible cleaning sheet 44; Finally, the driving gear-rack transmission assembly 411 drives the bonding member 43 to move above the storage area 4621. The driving ejecting member 463 drives the ejecting plate 464 to move to lift the flexible cleaning sheet 44 in the storage area 4621. The driving vertical driving member 413 drives the bonding member 43 to move downward to pick up a new flexible cleaning sheet 44, thereby completing the material change of the flexible cleaning sheet 44.
