Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic devices, in particular to a photovoltaic device with a cleaning device. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panel components, controllers and inverters. After a period of use, the solar panels will be contaminated with dust and sand, affecting the lighting effect, so they need to be cleaned.

[0003] Although the existing device can be mobile flushing, its connecting pipe for flushing is exposed to the sun for a long time, which can easily shorten its life; although the existing device can be wiped and cleaned, when wiping and moving, the cleaning block rubs the sand and moves, which can cause wear and tear of the solar panel.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a photovoltaic device with a cleaning device is provided, in order to achieve a more practical purpose. Summary of the invention

[0008] Furthermore, auxiliary protrusions are welded in a linear array on the left and right sides of the top surface of the mounting frame. The auxiliary protrusions are semi-cylindrical structures, and the inner sides of the left and right auxiliary protrusions are in contact with the left and right end surfaces of the photovoltaic panel respectively.

[0009] Furthermore, two spring rods are symmetrically welded on the bottom end surface of the inner wall of the first frame, and the protruding ends of the two spring rods are polished. After polishing, the lower ends of the two spring rods are both arc-shaped structures, and the protruding ends of the two spring rods are elastically in contact with the top surface of the mounting frame. The two spring rods are respectively aligned with the auxiliary protrusions on the left and right sides. When the two spring rods move forward with the first frame, the two spring rods and the auxiliary protrusions are in a continuous elastic clamping state.

[0010] Furthermore, an auxiliary part is installed on the mounting frame, and the auxiliary part consists of a base, a cleaning protrusion and an auxiliary block. A base with a concave structure is welded on the top surface of the mounting frame, and the front end surface of the base contacts the rear end surface of the photovoltaic panel. A rectangular hole is opened on the left and right sides of the base on the mounting frame.

[0011] Furthermore, the base is located in front of the cleaning block, and a cleaning protrusion with a triangular prism structure is welded on the top surface of the base. When the cleaning block moves forward, the bottom surface of the cleaning block elastically contacts the cleaning protrusion; an auxiliary block with an isosceles triangle block structure is welded in the recessed part of the base.

[0012] Furthermore, a flushing part is installed on the mounting frame, and the flushing part consists of a second frame, a water tank, a water pump, a connecting pipe, a nozzle, a first floating block, a connecting rod, a second floating block and a stopper. Two second frames with F-shaped structures are welded on the rear end face of the mounting frame, and a water tank with a rectangular box-shaped structure is welded on the top of the two second frames.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the present application, through the setting of the storage part, when the connecting pipe moves with the first frame, the pull rod will be pulled backward. When the first frame is reset, the connecting pipe will be hidden under the photovoltaic panel under the resetting action of the pull rod, thereby avoiding the connecting pipe from being exposed to the sun for a long time, which will eventually shorten its life. Compared with the existing devices, the present device can reduce maintenance costs.

[0017] The present application adopts the setting of the auxiliary part. Firstly, because the front end face of the base contacts the rear end face of the photovoltaic panel, when installing the photovoltaic panel, the front and rear limit of the photovoltaic panel can be achieved through the base, thereby improving the installation efficiency of the photovoltaic panel; secondly, when the first frame drives the cleaning block to move for cleaning, the cleaning block first contacts the cleaning protrusion, and the dust and sand at the bottom of the cleaning block can be scraped off under the scraping action of the cleaning protrusion, thereby ensuring the subsequent cleaning effect of the cleaning block on the photovoltaic panel; thirdly, the scraped dust and sand will fall onto the auxiliary block, and fall from the left and right sides of the base under the guidance of the auxiliary block, thereby ensuring the cleaning effect.

[0018] The present application arranges the mounting rod and the auxiliary protrusion. When the first frame drives the cleaning block to move for cleaning, continuous vibration can be generated through the continuous elastic clamping between the spring rod and the auxiliary protrusion. The continuous vibration can shake off the sand on the photovoltaic panel, thus avoiding the cleaning block pushing the sand to move and causing wear to the photovoltaic panel. The structure is more reasonable.

[0019] The present application arranges the first floating block, the connecting rod and the second floating block, so that rainwater can enter the water tank through the gap between the first floating block and the second floating block. The evaporation of water in the water tank can be reduced under the obstruction of the first floating block and the second floating block, and the structure is reasonable.
