A method for cleaning and folding photovoltaic panel components

Abstract

A method for cleaning and folding photovoltaic panel assemblies. Existing photovoltaic panel assemblies are mostly in an unfoldable state after being mounted on a fixed frame. In windy and dusty weather, the unfoldable state of the photovoltaic panel assemblies can easily cause problems such as sand and dust in the strong wind scratching the top coating of the photovoltaic panel. The present invention includes the following steps: when impurities on the top of the photovoltaic panel body need to be cleaned, a suction fan is activated, which drives airflow, thereby causing the airflow to enter the ventilation cavity and be discharged through the exhaust port. When the airflow is ejected, a portion of the surface of the photovoltaic panel body is further cleaned. The present invention is used for cleaning and folding photovoltaic panel assemblies.

Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and in particular relates to a method for cleaning and folding a photovoltaic panel assembly. Background Art

[0002] Photovoltaic power generation refers to the process of converting solar energy into electrical energy through a photovoltaic power generation system. Usually, the system is mainly composed of solar photovoltaic panels, combiner boxes, inverters, transformers and distribution equipment. At the same time, auxiliary systems such as monitoring systems, active and reactive power control systems, power prediction systems, five-protection systems and reactive power compensation devices form a complete photovoltaic power generation system.

[0003] Photovoltaic panels are a type of power generation device that generates direct current when exposed to sunlight. They are composed almost entirely of thin, solid-state photovoltaic cells made from semiconductor materials. To ensure the overall efficiency of photovoltaic power generation, most photovoltaic power stations are built in relatively open areas such as the Gobi Desert.

[0004] Most existing photovoltaic panel assemblies are in a non-foldable state after being installed on a fixed frame. When encountering strong winds and sandstorms, the photovoltaic panel assemblies are in a non-foldable state, and the dust in the strong wind is prone to scratching the top coating of the photovoltaic panel, which can easily cause overall damage to the photovoltaic panel assembly.

[0005] To this end, we propose a method for cleaning and folding photovoltaic panel components to solve the above problems. Summary of the Invention

[0006] The purpose of the invention is to remedy the deficiencies of the prior art and to provide a method for cleaning and folding a photovoltaic panel assembly.

[0007] The above purpose is achieved through the following technical solutions:

[0008] A method for cleaning and folding a photovoltaic panel assembly, the method comprising the following steps:

[0009] When it is necessary to clean impurities on the top of the photovoltaic panel body, the suction fan is started, and the suction fan drives the air flow, thereby causing the air flow to enter the ventilation cavity and be discharged through the exhaust port. When the air flow is ejected, a part of the surface of the photovoltaic panel body is assisted in cleaning. When it is necessary to clean the surface of the photovoltaic panel body as a whole, the servo motor is started, and the servo motor drives the rotating rod to rotate. The rotating rod and the slider are threaded together, so that the slider moves, and then the support rod moves, thereby assisting in supporting the cleaning plate; when it is necessary to fold the two mounting frames, the rotating motor is started, and the rotating motor drives the groove wheel to rotate. Under the action of the transmission belt, the two groove wheels are rotated, and then the two rotating rods are rotated. The rotating rod and the threaded groove are threaded together, so that the sliding rod moves, and then the support rod is extended, and the other mounting frame is pushed and folded; when it is necessary to install between two adjacent mounting frames, the positioning assembly is inserted into the socket, and the turntable is rotated. When the turntable rotates, the screw rod is driven to rotate, and the screw rod is threaded together with the push block, so that the push block is lowered, thereby squeezing out the ball as a whole, and then positioning it in the socket.

[0010] An installation cavity is provided at the top of the installation frame, and a photovoltaic panel body is embedded and installed in the installation cavity. A support cavity is symmetrically provided at the bottom of the installation frame, and a support assembly is provided in the support cavity; the support assembly includes a rotating rod rotatably arranged in the support cavity, a sliding rod is sleeved and installed on the rotating rod, a threaded groove is provided on the sliding rod, and the rotating rod and the threaded groove are threadedly engaged with each other, and the end of the sliding rod away from the rotating rod is hingedly installed with a support rod, and the end of the support rod away from the sliding rod is hingedly installed on the other installation frame, and the end of the rotating rod away from the sliding rod is fixed with a groove wheel, and the two groove wheels are engaged with each other through a transmission belt.

[0011] Thanks to the support assembly, the rotating motor drives the groove wheel to rotate, and under the action of the transmission belt, both groove wheels rotate, and then both rotating rods rotate. The rotating rods and the threaded grooves are threaded together, so that the sliding rod moves, and the support rod is extended, and the other installation frame is pushed and folded. When encountering strong winds and sandstorms, the two installation frames can be directly merged to retract the photovoltaic panel body as a whole, which can effectively protect the photovoltaic panel body when the sandstorm passes, and try to avoid the coating on the surface of the photovoltaic panel body being scratched.

[0012] The slide bar is in a rectangular rod-shaped structure. Limiting bars are horizontally fixed on both sides of the slide bar. A limiting groove for the limiting bar to slide is provided in the support cavity.

[0013] Thanks to the cooperation between the limit strips and the limit grooves, the slide rod can be stably slid in the support cavity during operation, and the situation in which the slide rod is misaligned and unable to slide effectively during operation can be avoided as much as possible.

[0015] There are a plurality of exhaust ports, which are equidistantly arranged on the installation cavity.

[0016] Thanks to the suction fan and several exhaust ports set at equal distances, impurities close to the inside can be blown out conveniently during work. A suction fan is installed at the bottom of the installation frame, and the air outlet of the suction fan is connected to the exhaust port.

[0019] Thanks to the positioning component, the positioning component is inserted into the socket, and the turntable is rotated. When the turntable rotates, the screw rod is driven to rotate, and the threads between the screw rod and the push block are matched, so that the push block is lowered, and the ball is squeezed out as a whole, and then positioned and inserted into the socket. During the work process, auxiliary positioning processing of two adjacent installation frames can be conveniently performed.

[0020] A fixing ring is fixed to the outer edge of the plug post, and the fixing ring is fixed to the bottom of the plug board by bolts.

[0021] Cleaning plates are hingedly installed on both sides of the installation frame corresponding to the installation cavity, and supporting cavities are opened on both sides of the installation frame corresponding to the installation cavity.

[0022] The supporting assembly comprises a rotating rod rotatably arranged in the supporting cavity, a sliding block is sleeved on the rotating rod, and a supporting rod is hingedly installed between the sliding block and the cleaning plate.

[0023] A protective pad is embedded and installed on one side of the two adjacent installation frames.

[0024] Thanks to the protective pad, when the two installation frames are close to each other during work, collisions will not occur, and the installation frames can be protected to a certain extent. Beneficial effects

In the event of a strong wind and sandstorm, the two mounting frames can be directly combined to allow the photovoltaic panel to be completely retracted. This effectively protects the photovoltaic panel during a sandstorm and minimizes scratches on the surface coating of the photovoltaic panel.

[0026] 2.
