Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic structures, and in particular to a foldable photovoltaic panel mechanism. Background Art

[0002] A photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). The photovoltaic panel assembly can convert solar energy and other thermal energy into electrical energy. The photovoltaic panel structure is a structure that includes the photovoltaic panel assembly and other components that support the photovoltaic panel assembly for power generation, cleaning, etc.

[0003] Most of the existing solar panel photovoltaic panel mechanisms are in an unfoldable state after being installed on a fixed frame. The photovoltaic panel components are always exposed to the external environment and are easily damaged when encountering extreme weather. For example, the photovoltaic panel components are easily eroded by rain and snow in rainy and snowy weather. Especially under conditions of severe air pollution, the acidity in rainwater is relatively high, which will corrode the photovoltaic materials and sealing materials on the surface of the photovoltaic panel mechanism, greatly reducing the service life of the photovoltaic panel mechanism; and a layer of dust will accumulate on the surface of the photovoltaic panel mechanism due to long-term exposure to the sun, reducing the production efficiency. Therefore, a cleaning component needs to be installed on each photovoltaic panel mechanism, which is expensive and not economical. Summary of the invention

[0004] The purpose of the present invention is to provide a foldable photovoltaic panel mechanism, which can solve the above-mentioned technical problems, facilitate folding and protecting the photovoltaic panel mechanism, save cleaning components, and facilitate and quickly clean up.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a foldable photovoltaic panel mechanism, comprising two fixed plates, a plurality of photovoltaic panel assemblies are arranged between the two fixed plates, a cylinder is hinged between the photovoltaic panel assemblies, and the two sides of the bottom of the cylinder are hinged to the adjacent photovoltaic panel assemblies to form a photovoltaic panel assembly chain, one end of the photovoltaic panel assembly chain is fixedly connected to the fixed plate, and the other end is movably connected to the other fixed plate, support rods are fixedly provided at the ends of both sides of the photovoltaic panel assembly, the top ends of the two adjacent support rods are connected by a connecting rod, the support rods and the connecting rods on one side of the same photovoltaic panel assembly are trapezoidal, rotating rods are hinged at both ends of the cylinder piston rod, the lower end of the rotating rod is hinged to the support rod, and a cleaning assembly is provided on the fixed plate fixedly connected to the photovoltaic panel assembly chain.

[0006] By adopting the above technical scheme, the bottom of the cylinder is connected to the photovoltaic panel assembly, and when the cylinder piston rod is extended, it drives the rotating rod to hinge one end of the piston rod upward, and the tail end of the connecting rod is hinged to the support rod. Multiple photovoltaic panel assemblies form a photovoltaic panel assembly chain. When all the cylinder piston rods are extended, the photovoltaic panel assembly chain away from one end of the cleaning assembly is driven to gradually fold and curl upward until the photovoltaic panel assembly chain is connected end to end to form a circle. At this time, the smooth surface of the photovoltaic panel assembly is located in the inner wall of the circle formed by the photovoltaic panel assembly chain, which is convenient for folding, and can avoid damage to the photovoltaic panel mechanism caused by extreme weather, thereby protecting the photovoltaic panel assembly and extending the service life of the photovoltaic panel assembly. A cleaning assembly is also provided to regularly clean the circular photovoltaic panel assembly chain, and the photovoltaic panel assembly chain can be cleaned without setting an extra-long or multiple cleaning assemblies. Cleaning is convenient and economical.

[0007] The present invention is further configured as follows: the cleaning component includes a bracket, a rotating shaft is rotatably provided on the bracket, a plurality of connecting rods are fixedly provided on the outer wall of the rotating shaft, a sliding sleeve on the connecting rod is provided with a cylindrical sleeve and a fixed ring, a spring is provided between the cylindrical sleeve and the fixed ring, both ends of the spring are respectively fixedly connected to the fixed sleeve and the fixed ring, a same cross bar is provided on the top ends of the plurality of cylindrical sleeves, a cleaning brush is fixedly provided on the outer side of the cross bar, and when the spring is in a compressed state, the cleaning brush abuts against the photovoltaic panel assembly.

[0008] By adopting the above technical solution, the rotating shaft is rotated, and the rotating shaft drives the connecting rod and the cross bar to rotate. A cleaning brush is provided on the outer wall of the cross bar. When the cross bar rotates, the photovoltaic panel assembly chain folded into a circle can be cleaned, and impurities on the smooth surface of the photovoltaic panel assembly can be cleaned, thereby improving the power generation efficiency of the photovoltaic panel assembly; one end of the spring is fixedly connected to the fixing sleeve, and the other end is fixedly connected to the fixing ring, and when the spring is compressed, the cleaning brush abuts against the photovoltaic panel assembly, so that the spring is forced to drive the fixing sleeve to move away from the rotating shaft, so that the cleaning brush is forced to closely abut against the photovoltaic panel assembly, and the attached impurities that are difficult to clean are cleaned, thereby ensuring the cleaning effect.

[0009] The present invention is further configured as follows: a sliding block is fixedly provided at one end of the connecting rod away from the rotating shaft and is slidably connected in the cylindrical sleeve.

[0010] By adopting the above technical solution, a slider is provided to realize the sliding connection between the connecting rod and the cylindrical sleeve, and at the same time, it can also play a limiting role to prevent the cylindrical sleeve from being separated from the connecting rod.

[0011] The present invention is further configured as follows: a dust outlet is provided between the photovoltaic panel assembly fixed on the fixing plate and the photovoltaic panel assembly adjacent thereto.

[0012] By adopting the above technical solution, the cleaning brush drives the brushed impurities to the dust outlet every time it rotates along the circular photovoltaic panel assembly chain, so that the impurities fall off the photovoltaic panel assembly chain, further improving the cleaning efficiency.

[0013] The present invention is further configured as follows: it also includes a micro motor, the micro motor is electrically connected to the solar panel, and the micro motor is fixedly connected to the rotating shaft.

[0014] The present invention is further configured to include a controller, which is used to control the micro motor to start.

[0015] By adopting the above technical solution, the solar panel generates electricity to supply the micro motor, and the remote controller controls the micro motor to start at a fixed time to drive the shaft to rotate to clean the photovoltaic panel component chain, thereby achieving regular cleaning of the photovoltaic panel components.

[0016] The present invention is further configured as follows: a round rod is fixedly arranged on a fixed plate away from the cleaning assembly, a clamping groove is arranged at the bottom of the photovoltaic panel assembly chain, and the round rod is clamped in the clamping groove.

[0017] By adopting the above technical solution, when the photovoltaic panel assembly chain is straightened, it is away from the cleaning assembly and the photovoltaic panel assembly is fixed to the fixed plate through the card slot, so as to prevent the photovoltaic panel assembly chain from shaking and detaching from the fixed plate.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention forms a photovoltaic panel assembly chain by hingedly connecting photovoltaic panel assemblies at both ends of the bottom of multiple cylinders, and hingedly connecting rotating rods at both ends of the cylinder piston rods. When the piston rod is extended, it drives the rotating rod to hinge one end of the piston rod upward, and the tail end of the rotating rod is hinged to the support rod. When all the cylinder piston rods are extended, the photovoltaic panel assembly chain away from one end of the cleaning assembly is driven to gradually fold and curl upward until the photovoltaic panel assembly chain is connected end to end to form a circle. At this time, the light surface of the photovoltaic panel assembly is located in the inner wall of the circle formed by the photovoltaic panel assembly chain, which is convenient for folding, can avoid damage to the photovoltaic panel assembly caused by extreme weather, and play a role in protecting the photovoltaic panel assembly and extending the service life of the photovoltaic panel assembly; in normal weather, all cylinder piston rods are contracted to drive the photovoltaic panel assembly chain to return to its original state.

[0020] 2. When the photovoltaic panel assembly chain is connected end to end to form a circle, the rotating shaft of the cleaning assembly drives the connecting rod and the cross rod to rotate. A cleaning brush is provided on the outer wall of the cross rod. When the cross rod rotates, the photovoltaic panel assembly chain folded into a circle can be cleaned to remove impurities on the smooth surface of the photovoltaic panel assembly, thereby improving the power generation efficiency of the photovoltaic panel assembly. One end of the spring is fixedly connected to the fixing sleeve and the other end is fixedly connected to the fixing ring. When the spring is compressed, the cleaning brush abuts against the photovoltaic panel assembly, so that the spring is forced to drive the fixing sleeve to move away from the rotating shaft, so that the cleaning brush is forced to closely abut against the photovoltaic panel assembly, and the attached impurities that are difficult to clean are cleaned, thereby ensuring the cleaning effect. The photovoltaic panel assembly chain can be cleaned without setting up extra-long or multiple cleaning assemblies. Cleaning is convenient and economical. BRIEF DESCRIPTION OF THE DRAWINGS
