[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 panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices; photovoltaic panels are the most common components in photovoltaic power generation.

[0003] The temperature of the environment will have a great impact on the quality of photovoltaic panels. Too high or too low temperature will affect the performance of photovoltaic panels, resulting in deformation. High temperature will cause the material to expand, while low temperature may cause the material to shrink. These changes may cause the photovoltaic panel to deform.

If the photovoltaic panel is in a flat state, then when monitoring is performed through multiple groups of flatness monitoring components, the displacement distances of the flatness monitoring components are the same.

[0010] By adopting the above technical solution, excessively high or low temperature will cause the photovoltaic panel to deform, and the deformation position can be known through the flatness monitoring component. At this time, the action of the driving component in the water storage assembly can be controlled to promote the movement of the sealing plate, and the hot water or cold water reserved in the warehouse can be discharged through the first water outlet through the sealing plate, thereby flushing the corresponding deformation position. Since the deformation position of the photovoltaic panel is generally a problem of the internal material, its surface is covered with a glass sheet, and the photovoltaic panel material at the corresponding position will become plastic through heating, and then under the action of the rebound force of the glass sheet, the principle of thermal expansion and contraction can be used to perform a certain degree of recovery, so that the slightly deformed photovoltaic panel can be roughly restored to its original state, and at the same time, the dust on the photovoltaic panel can be cleaned to improve the power generation efficiency of the photovoltaic panel.

At this time, it cannot be identified by the second transverse monitoring rod, and can only be monitored by the second longitudinal monitoring rod. At this time, the displacement direction of the second longitudinal monitoring rod is perpendicular to the direction of the crack. When the crack monitoring head contacts the position of the crack, some tension will be generated to cause it to detach from the slot.

At this time, the connecting seat is continued to be driven to slide. At this time, the guide rod will gradually tilt under the action of the deformation area, and the two guide rods will form a triangular area, which is convenient for concentrating the repair water flow and making it easier for the water flow to contact the position to be repaired, making the operation simpler and more convenient.

[0031] 2. By setting up a torsion spring structure and rotatably connecting the guide rod to the connecting seat, when the photovoltaic panel is deformed and restored by the heated or cooled water flow in the bin body, the guide rod with the rubber contact piece can be driven to contact the edge of the deformation area.

The elastic component includes a guide rod 5411 fixedly connected to the inside of the sliding block 541 and a restoring spring 5412 sleeved on the guide rod 5411. A connecting piece 5413 is fixedly connected to the sealing component 542, which is sleeved on the guide rod 5411 through the connecting piece 5413 and moves away from the photovoltaic panel 1 under the action of the restoring spring 5412.

[0051] The working principle of a photovoltaic panel monitoring device in this application is: When monitoring is performed through the monitoring device 2, the lateral and longitudinal displacements can be performed through the first lateral monitoring rod 22 and the first longitudinal monitoring rod 23. If the photovoltaic panel 1 is in a flat state, the displacement distances of the flatness monitoring components 25 are the same when monitoring is performed through multiple sets of flatness monitoring components 25. If it is not flat, the displacement distances of the flatness monitoring components 25 are different, which makes it easier to determine the position of the deformation of the photovoltaic panel 1. Too high or too low temperature will cause the photovoltaic panel 1 to deform. The deformation position can be known through the flatness monitoring component 25. At this time, the driving component 33 in the water storage component 3 can be controlled to move, thereby pushing the sealing plate 32 to move. 32 can discharge the hot water or cold water reserved in the bin body 31 through the first water outlet 34, and then flush the corresponding deformation position, so as to facilitate the deformation recovery of the photovoltaic panel 1. By setting the torsion spring structure 45 and the guide rod 4 rotatably connected to the connecting seat 43, when the photovoltaic panel 1 is deformed and restored by the heated or cooled water flow in the bin body 31, the guide rod 4 with the rubber resistance sheet 41 can be driven to contact the edge of the deformation area. At this time, the connecting seat 43 is continued to be driven to slide. At this time, the guide rod 4 will gradually tilt under the action of the deformation area, and the two guide rods 4 will form a triangular area, which is convenient for concentrating the repair water flow and making it easier for the water flow to contact the position to be repaired.

[0052] During the use of the photovoltaic panel 1, the crack monitoring component 53 is set up to monitor whether there are cracks on the back of the photovoltaic panel 1. The monitoring can be carried out by sliding the second transverse monitoring rod 51 and the second longitudinal monitoring rod 52. When sliding to the position where the crack exists, the crack monitoring head 533 will stop moving temporarily under the blocking effect of the crack. At this time, the tension detected by the tension sensor 531 will increase, and then it is known that a crack or damage has occurred at the corresponding position, which is convenient for the staff to carry out maintenance; at this time, if the direction of the crack is longitudinal, the sliding direction of the second transverse monitoring rod 51 is parallel to the direction of the crack. At this time, it cannot be identified by the second transverse monitoring rod 51, and can only be monitored by the second longitudinal monitoring rod 52. At this time, the displacement direction of the second longitudinal monitoring rod 52 is perpendicular to the direction of the crack. When the crack monitoring head 533 contacts the position of the crack, some tension will be generated to cause it to detach from the slot. At this time, the tension sensor 531 can identify the tension information and then determine the location of the crack.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
