Most of the current solar panel brackets are fixed on the ground, which limits the angle adjustment of the solar panels and affects their daylighting rate. At the same time, when solar panels installed outdoors encounter strong winds, the solar panels and brackets are very likely to be blown over due to the large windward surface of the solar panels, affecting their use. Therefore, it is necessary to improve them. Summary of the invention

[0007] Step 1: Install the solar panel on the sleeve;

[0008] Step 2: Start the motor, drive the connecting ring to rotate through the transmission gear, and then drive the frame to rotate, so that the solar panel can face the sun to increase the daylighting rate;

[0009] Step 3: When encountering strong winds, the wind drives the wind plate to rotate, which in turn drives the rod body to move upward, and the rod body drives the movable ring and the transmission rod to move upward, which in turn drives the cross bar II to move upward, causing the frame to deform, driving the angle between the solar panel and the horizontal plane to decrease, thereby reducing the windward area of ​​the solar panel to avoid the solar panel from tipping over.

[0010] Compared with the prior art, the beneficial effects of the present invention are: the present invention can not only adjust the angle of the solar panel, but also drive the bottom of the solar panel to move upward in windy weather, so as to reduce the angle between the solar panel and the horizontal plane, thereby reducing the windward area of ​​the solar panel, so as to reduce the occurrence of solar panel tipping over.

[0030] The transmission rod 56 is a multi-stage telescopic rod.

[0031] A method for using a bracket for improving the daylighting rate of a solar panel, the method comprising the following steps:

[0032] Step 1: Install the solar panel on the sleeve 11;

[0033] Step 2: Start the motor to drive the connecting ring 41 to rotate through the transmission gear, thereby driving the frame 3 to rotate, so that the solar panel can face the sun to increase the daylighting rate;

[0034] Step 3: When encountering strong winds, the wind drives the wind plate 22 to rotate, thereby driving the rod body 52 to move upward, and the rod body 52 drives the movable ring 53 and the transmission rod 56 to move upward, thereby driving the cross bar II 15 to move upward, causing the frame 1 to deform, driving the angle between the solar panel and the horizontal plane to decrease, thereby reducing the windward area of ​​the solar panel to avoid the solar panel from tipping over.

[0035] The working principle of the present invention is as follows: when using the device, the solar panel is installed on the sleeve 11; when the angle of the solar panel needs to be adjusted, the motor is started, the motor drives the transmission gear to rotate, and at the same time the tooth groove 43 drives the connecting ring 41 to rotate, and then drives the cross bar Ⅰ15 to rotate through the connecting rod 42, and the cross bar Ⅰ15 drives the frame 1, the transmission rod 56 and the movable ring 53 to rotate around the column 3, so that the solar panel can always face the sun, thereby improving the daylighting rate;

[0036] When encountering strong winds, the wind will blow the wind plate 22 to rotate, the wind plate 22 drives the round rod 21 to rotate, and the round rod 21 drives the rod body 52 to move. Since the limiting rod 55 on the side of the rod body 52 slides with the limiting groove 33, the rod body 52 is restricted from rotating. Therefore, during the rotation of the round rod 21, the rod body 52 is driven to move upward through the cooperation of the slider 51 and the spiral groove 24, and the rod body 52 drives the limiting rod 55 to move upward. The limiting rod 55 drives the movable ring 53 to move upward through the annular groove 54, and the movable ring 53 drives the transmission rod 56 to move upward. Since the transmission rod 56 is a telescopic rod, and the lower end of the fixed rod II14 of the frame body 1 It is inclined in the direction away from the column 3, so when the transmission rod 56 moves upward to drive the cross bar II 15 to move upward, the cross bar II 15 pushes the bottom end of the fixing rod II 14 to move in the direction away from the column 3, thereby driving the fixing rod I 16 to move in the direction away from the column 3, thereby causing the sleeve 11 and the slide bar 12 to move relative to each other, thereby increasing the total length, reducing the angle between the sleeve 11 and the horizontal plane, and reducing the angle between the solar panel arranged on the sleeve 11 and the horizontal plane, so as to achieve the purpose of reducing the windward area of ​​the solar panel, reducing the external force on the solar panel, and reducing the probability of the solar panel and the bracket being overturned by strong wind;

[0037] The greater the wind force, the smaller the angle between the solar panel and the horizontal plane; and in the process of the solar panel moving, the rod body 52 moves upward and also drives the connecting tube 61 to move upward, and the connecting tube 61 drives the protective tube 612, the cylinder 615, and the fixed tube 616 to move upward, so that the sliding device 6 stretches;

[0038] When the wind stops, under the action of gravity, the solar panel drives the frame 1 to move to the initial position, and the rod body 52 is driven downward by the transmission rod 56, the movable ring 53 and the limit rod 55. During the downward movement, the rod body 52 pushes the connecting tube 61 to move downward. Since the friction between the slide groove II 632 and the protrusion II 617 is less than the friction between the protrusion I 613 and the slide groove I 614, the friction between the protective tube 612 and the cylinder 615 is large during the downward movement of the connecting tube 61. The two are relatively stationary at first, and the cylinder 615 drives the fixed tube 616 to move downward relative to the outer tube 63. After the fixed tube 616 moves to the lowermost end, part of the through hole III 631 is blocked, reducing the contact area of ​​the through hole III 631 with the outside world, reducing the exhaust volume through the through hole III 631, thereby increasing the pressure in the sliding device 6 and slowing down the downward impact force of the rod body 52. , thereby reducing the impact force of the solar panel and the frame 1 on the ground during the downward movement, and reducing the damage caused by the impact force; after the fixing cylinder 616 moves to the lowermost end, the connecting cylinder 61 drives the protective cylinder 612 to move downward relative to the cylinder 615 until the frame 1 and the rod body 52 are moved to the initial position, so that the bottom of the solar panel is not subject to resistance when moving upward, and can quickly reduce the windward area to avoid being blown over. After being unaffected by the wind, it can slowly fall, avoiding excessive interaction force with the ground that causes damage to the frame 1 and the solar panel; at the same time, when the solar panel moves slowly downward, it can also effectively increase the time for the solar panel to move to the original position, thereby avoiding continuous strong winds blowing towards the device. After the solar panel is affected by strong winds on the way down, the upward moving distance can be shortened, thereby avoiding the situation where the solar panel cannot reduce the windward area in time under continuous strong winds and is blown over.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
