Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic cleaning, and in particular to a photovoltaic panel with matching cleaning accessories. Background Art

[0002] With the growing global demand for clean energy, solar energy has been widely used as a renewable energy source. As the core equipment of solar power generation, the conversion efficiency and long-term stable operation of photovoltaic panels are crucial to the performance of the entire photovoltaic power generation system. However, in practical applications, the cleanliness of photovoltaic panels has always been one of the important factors affecting their power generation efficiency.

[0003] Currently, photovoltaic panel cleaning operations mainly rely on rotating brushes to remove surface dirt. Although the brush cleaning system performs well in cleaning effects, it also has some shortcomings. The friction between the brush and the surface of the photovoltaic panel can easily cause wear on the battery cells and affect the photoelectric conversion effect of the photovoltaic panel. Since the length of the brush needs to be customized according to the width of the photovoltaic panel, it can only be used for the cleaning needs of photovoltaic panels of specific specifications, which limits its scope of use to a certain extent. Summary of the invention

[0004] The present invention relates to a photovoltaic panel with a matching cleaning accessory. According to the difference in width of photovoltaic panels of different specifications, the positions of two left and right movable end frames can be flexibly adjusted to change the spacing distance between them. Under the thrust of the spring, the movable end frame moves inward so that the roller can fit closely to the surface of the photovoltaic panel. The photovoltaic panel has excellent universal performance, can meet the matching cleaning needs of photovoltaic panels of various specifications, and shows excellent flexibility and practicality.

[0005] According to a first aspect of the present invention, there is provided a photovoltaic panel with supporting cleaning accessories, specifically comprising: a main support frame, a motor, a transmission screw, a movable middle frame, a movable end frame, a roller, a guide tube group, a hose and a pulley; a photovoltaic panel is arranged at the bottom of the main support frame, and the main support frame is located on the top of the photovoltaic panel; a motor is installed at the bottom end of the main support frame, and a transmission screw is connected inside the main support frame, and the drive shaft of the motor is connected to the transmission screw; a movable frame is connected to the outside of the main support frame, and the movable frame is centrally located on the top of the photovoltaic panel; movable end frames are connected at both ends of the movable frame, and the two movable end frames are symmetrically located at the two ends of the top of the photovoltaic panel; two rollers are connected inside the movable end frame; a guide tube group is installed on the top of the movable frame, and the guide tube group is connected to the movable end frame; a hose is connected to the top of the movable frame, and the hose is connected to the guide tube group, and a pulley is connected to the top of the movable frame.

[0006] Furthermore, cross bars are symmetrically arranged inside the main support frame, guide holes are symmetrically arranged inside the movable middle frame, and the cross bars slide through the guide holes provided in the movable middle frame, and the movable middle frame is guided to move through the sliding cooperation between the guide holes and the cross bars.

The guide rod A slides through the sliding hole B provided on the movable end frame, and the movable end frame is guided by sliding cooperation between the guide rod B and the sliding hole A, and between the guide rod A and the sliding hole B.

[0011] Furthermore, a spring is sheathed on the outside of the guide rod A, one end of the spring is in contact with the movable middle frame, and the other end of the spring is in contact with the movable end frame. The spring has an elastic reset effect on the movable end frame. The left and right movable end frames can be moved and adjusted according to the different widths of photovoltaic panels of different specifications, and the distance between the left and right movable end frames can be changed. The movable end frame moves inward under the influence of the spring thrust, so that the roller is in close contact with the photovoltaic panel.

[0012] Furthermore, a pipe rack A is welded on the top of the movable middle frame, a pipe rack B is welded on the top of the movable end frame, and the guide pipe group is connected to the pipe rack A and the pipe rack B.

[0015] The present invention provides a photovoltaic panel with a matching cleaning accessory, which has the following beneficial effects: When the present invention is in use, the movement of the movable frame is guided by the sliding cooperation between the guide hole and the cross bar; when it is necessary to clean the dust attached to the top of the photovoltaic panel, the motor drives the transmission screw to rotate, thereby driving the movable frame to move along the cross bar, and the movable frame synchronously drives the left and right movable end frames to move, and the rollers roll in contact with the sides of the photovoltaic panel to reduce the friction coefficient between the movable end frames and the photovoltaic panel; at the same time, the movable frame and the movable end frames drive the upper guide pipe group to move, and the nozzle sprays water to effectively clean the dust on the top of the photovoltaic panel, thereby ensuring the photoelectric conversion effect of the photovoltaic panel.

[0016] In addition, through the sliding cooperation between the guide rod B and the slide hole A, and the sliding cooperation between the guide rod A and the slide hole B, a stable and precise movement guide is provided for the movable end frame, and an elastic reset force is applied to the movable end frame through the spring; according to the difference in width of photovoltaic panels of different specifications, the positions of the left and right movable end frames can be flexibly adjusted to change the spacing distance between them. Under the thrust of the spring, the movable end frame moves inward, so that the roller can fit closely to the surface of the photovoltaic panel.

[0017] In addition, the number of hoses, tees and nozzles can be flexibly adjusted according to the different spacing distances between the left and right movable end frames. During specific operations, the hoses, tees and nozzles are reasonably combined and fixedly installed on the movable middle frame and the movable end frame to meet the actual needs of photovoltaic panel cleaning applications; when the guide tube group slowly moves downward, it will pull the hose forward and extend it, while driving the counterweight block to rise. On the contrary, during the upward movement of the guide tube group, the hose is pulled back under the gravity of the counterweight block to ensure that the hose is always in a taut state, effectively preventing the problem of hose entanglement, thereby ensuring the smooth movement of the movable bracket and improving the stability and reliability of the entire operation.
