Description

Technical Field

[0001] The utility model relates to the technical field of wind protection for photovoltaic power stations, in particular to a wind protection mechanism for photovoltaic power stations. 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. Photovoltaic power generation mostly converts light energy into electrical energy through solar panels installed on support frames. In order to increase the light receiving rate of solar panels, they are generally installed in open spaces. In windy weather, solar panels are easily damaged by strong winds due to their tilted characteristics. In order to reduce the damage to solar panels caused by wind, windproof mechanisms are installed.

[0003] In order to prevent the solar panel's light receiving rate from being affected when the windproof mechanism is installed, the windproof mechanism is far away from the solar panel, which has a poor effect on blocking wind force. If the distance to the solar panel is close, it will block light. Therefore, a windproof mechanism for a photovoltaic power station is proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model embodiment provides a wind protection mechanism for a photovoltaic power station, such as Figure 1 , 6 As shown, it includes a supporting main frame 1 and a solar mounting frame 2, the solar mounting frame 2 is fixedly sleeved on the outer surface of the supporting main frame 1, a ball ring frame 12 is fixedly installed on the upper end of the solar mounting frame 2, a ball rod 3 is rotatably inlaid inside the ball ring frame 12, a wind receiving plate 13 is fixedly inserted on the upper end of the ball rod 3, the upper end of the ball ring frame 12 is a spherical notched ring structure, the end of the ball rod 3 located inside the ball ring frame 12 is spherical, the center of the spherical structure of the ball rod 3 is concentric with the center of the spherical ring structure of the ball ring frame 12, and coincides with the axis of the supporting main frame 1, a plurality of wind receiving plates 13 are arranged, and the plurality of wind receiving plates 13 are distributed in a circular array around the axis of the ball rod 3, and when the wind receiving plate 13 is driven by wind, the ball rod 3 can be driven to deflect.

[0028] The lower end of the club 3 is fixedly connected to a long rope 4, and a movable inner column 5 is slidably inserted inside the supporting main frame 1. The lower end of the long rope 4 is fixedly connected to the upper end surface of the movable inner column 5, and the upper surface of the movable inner column 5 is fixedly connected to a compression spring 6. The upper end of the compression spring 6 is fixedly connected to the inner wall of the supporting main frame 1. The compression spring 6 has a tendency to push the movable inner column 5 to move downward to straighten the long rope 4. The outer surface of the supporting main frame 1 and the lower part of the solar mounting frame 2 are slidably sleeved with a wind shielding ring plate 7. The outer ring surface of the wind shielding ring plate 7 is a streamlined curved surface, and the inner ring space of the wind shielding ring plate 7 is larger than the space between the supporting main frame 1 and the solar mounting frame 2. When the wind contacts the outer ring streamlined curved surface of the wind shielding ring plate 7, the wind flows upward under the action of the streamlined curved surface of the wind shielding ring plate 7, thereby reducing the thrust caused by the wind.

[0029] A pressure sensing starter 8 is fixedly installed on the outer surface of the supporting main frame 1 and below the wind shielding ring plate 7. An electric telescopic rod 9 is installed on the outer surface of the pressure sensing starter 8. The upper end of the electric telescopic rod 9 is fixedly connected to the bottom surface of the wind shielding ring plate 7. The inner ring surface of the pressure sensing starter 8 is fixedly penetrated through the outer surface of the supporting main frame 1. When the pressure sensing starter 8 is subjected to pressure, the electric telescopic rod 9 can be activated to control the wind shielding ring plate 7 to move upward, so as to shield the surrounding areas of the solar mounting frame 2. The lower end of the movable inner column 5 slides through the pressure sensing starter 8 The upper surface of the main support frame 1 is provided with a bottom cylinder 10 inside, and the bottom surface of the bottom cylinder 10 is elastically connected to the inner bottom wall of the main support frame 1 through a tension telescopic rod 18. A buffer pressure cylinder 15 is provided above the bottom cylinder 10, and the lower end of the movable inner column 5 is located on the inner annular surface of the buffer pressure cylinder 15. The outer annular surface diameter of the buffer pressure cylinder 15 is equal to the inner annular surface diameter of the bottom cylinder 10. The buffer pressure cylinder 15 is elastically connected to the inner annular surface of the bottom cylinder 10 through an elastic telescopic rod 17. When the bottom cylinder 10 moves upward, the buffer pressure cylinder is pushed by the elastic telescopic rod 17. 15 applies pressure to the pressure sensing starter 8 upwards. When the bottom cylinder 10 continues to move upwards, the elastic telescopic rod 17 achieves a buffering effect by compression. The bottom cylinder 10 is slidably sleeved on the outer surface of the movable inner column 5. The bottom end surface of the movable inner column 5 is installed with a push plate 11. The outer ring surface of the bottom cylinder 10 is set as an uneven surface. The outer surface of the bottom cylinder 10 is slidably sleeved with a friction cylinder 14. The inner ring surface of the friction cylinder 14 is set as an uneven surface. The friction cylinder 14 is fixedly inserted in the interior of the supporting main frame 1. When the wind force changes rapidly, when the push plate 11 is pressed, the bottom cylinder 10 is pressed against the outer surface of the movable inner column 5. When the bottom cylinder 10 moves downward frequently, it slows down and resets downward under the friction of the friction cylinder 14, which increases the time for the buffer pressure cylinder 15 to apply pressure to the pressure sensing starter 8, effectively preventing the wind shield ring plate 7 from moving up and down frequently. The bottom cylinder 10 is slidably sleeved on the outer surface of the movable inner column 5 through the fork frame 16. The outer ring surface of the fork frame 16 is in the form of three rod-shaped structures. The bottom surface of the buffer pressure cylinder 15 is located above the rod-shaped structure of the fork frame 16 and is set in a notch shape. When the bottom cylinder 10 drives the fork frame 16 to move upward, it can enter the notch of the buffer pressure cylinder 15.

[0030] Working principle: when there is no wind, the compression spring 6 pushes the movable inner column 5 to the bottom, and the pressure sensing starter 8 is not subjected to pressure. The electric telescopic rod 9 is controlled to drive the wind shield ring plate 7 to be located below the solar mounting frame 2 to prevent sunlight shading. When the wind-receiving plate 13 is pushed by the wind to drive the club 3 to deflect, the lower end of the club 3 drives the movable inner column 5 to push the bottom cylinder 10 upward through the push plate 11 by pulling the long rope 4. The bottom cylinder 10 pushes the buffer pressure cylinder 15 through the elastic telescopic rod 17 to apply pressure to the pressure sensing starter 8. The electric telescopic rod 9 is started to push the wind shield ring plate 7 to move upward. The wind is blocked on all sides of the solar mounting frame 2. When the wind changes frequently, when the push plate 11 moves downward frequently, the bottom cylinder 10 slows down and resets downward under the friction of the friction cylinder 14, thereby increasing the time for the buffer pressure cylinder 15 to apply pressure to the pressure sensing starter 8, effectively preventing the wind shield ring plate 7 from moving up and down frequently.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
