Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation panels, in particular to a photovoltaic power generation panel supporting device. Background Art

[0002] Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight into electrical energy. Whether it is used independently or connected to the grid, the photovoltaic power generation system mainly consists of three parts: solar panels (modules), controllers and inverters.

[0003] Photovoltaic panels are supported by support frames when in use. Since solar power generation is located in a relatively open area outdoors and in order to increase the light collection rate, they are generally tilted. In windy weather, the solar panels will be pushed by the wind. In order to reduce the damage to the solar panels caused by the wind, a buffer structure is installed on the support device in the prior art. When the solar panels are pushed by the wind, the wind force is buffered by pushing the elastic elements to deform. However, when the wind is strong, the solar panels will shake greatly, which can easily cause damage to the solar panels. Therefore, a photovoltaic panel support device is proposed.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0029] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0031] Photovoltaic panels are supported by support frames when in use. Since solar power generation is located in a relatively open area outdoors and in order to increase the light collection rate, they are generally tilted. The wind will exert thrust on the solar panels, increasing the burden on the supporting structure.

[0032] In the related art, in order to reduce the damage caused by wind to solar panels, a buffer structure is installed on the supporting device. When the solar panel is pushed by the wind, the wind force is buffered by pushing the elastic element to deform. However, when the wind is strong, the solar panel will shake greatly, which may easily cause damage to the solar panel.

[0033] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a photovoltaic panel support device. When the wind force is relatively small, the mounting base plate 2 is pushed by the wind to apply torque to the fixed rod 7 through the main shaft 3. The fixed rod 7 drives the buffer block 6 and the toothed card plate 5 to move in an offset manner through the connecting spring 9, and at the same time pushes the arc-shaped telescopic rod 13 to be compressed, so as to buffer the wind force exerted on the mounting base plate 2. When the wind force is relatively strong, when the right end of the mounting base plate 2 rotates downward to a large extent under the push of the wind, the mounting base plate 2 exerts a large pressure on the arc-shaped telescopic rod 13 through the main shaft 3 and the fixed rod 7. As the thrust exerted on the corner block 10 increases, the corner block 10 gradually compresses the spring telescopic rod 11 through contact with the block 12. After the corner block 10 is dislocated with the block 12, the right end of the mounting base plate 2 quickly rotates downward and flattens, so as to quickly reduce the force area of ​​the mounting base plate 2 exposed to the wind.

[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:

The upper surface of the fixed rod 7 located inside the same inner ring disk 8 is connected to the fixed end of the spring telescopic rod 11 through an arc telescopic rod 13. As the compression degree of the arc telescopic rod 13 increases, the corner block 10 The spring telescopic rod 11 is gradually compressed by contact with the stop block 12.
