[0034] Please refer to the attached Figure 1 - attached Figure 8 , an adjustable bracket for a distributed photovoltaic power generation panel, including a box body 1, and further including: a placing plate 5, a connecting component, a blocking component and a detecting and driving component. The placing plate 5 is slidably disposed inside the box body 1, and a photovoltaic panel 2 is disposed above the placing plate 5. Four ends of the inner bottom of the box body 1 are vertically and fixedly installed with first spring rods 18, and the telescopic ends of the four first spring rods 18 are fixedly installed at the bottom of the placing plate 5. The connecting component is disposed on the placing plate 5 and is used to connect the photovoltaic panel 2. The blocking component is disposed on the box body 1 and is used to shield and protect the photovoltaic panel 2 entering the inside of the box body 1. The detecting and driving component is disposed on the box body 1 and is used to detect the wind outside and automatically protect the photovoltaic panel 2 when the wind is strong;

[0035] Through the above setting of the detecting and driving component, it can automatically detect in strong wind weather, and can also make the detecting and driving component work after detecting strong wind weather, so as to realize that the placing plate 5 drives the photovoltaic panel 2 to enter the box body 1 together to protect it.

[0036] Please refer to the attached Figure 1 - attached Figure 8, in a preferred embodiment, the detection driving assembly includes: a rotating rod 4. An extension plate is horizontally and fixedly installed on the side of the box body 1, and the rotating rod 4 is vertically rotatably installed on the top of the extension plate. A rotating table 14 is rotatably installed at the top of the rotating rod 4, and a vertical rod 15 is vertically and fixedly installed on the top of the rotating table 14. A cross rod 16 is horizontally penetrated and fixed on the vertical rod 15, and a wind vane 17 is fixedly installed at the end of the cross rod 16. A sleeve 12 is rotatably sleeved on the top surface of the cross rod 16, and a fan blade 13 is fixedly installed at the top of the sleeve 12. A second pulley 10 is fixedly sleeved on the surface of the sleeve 12, and a first pulley 9 is arranged below the second pulley 10. A first belt 8 is sleeved on the surfaces of the first pulley 9 and the second pulley 10, and a U-shaped rod 11 fixed to the surface of the vertical rod 15 is rotatably installed outside the first pulley 9. A large pulley 36 of a first bevel gear 6 is fixedly sleeved on the surface of the rotating rod 4, and a second bevel gear 7 is fixedly installed on one side of the first pulley 9. The first bevel gear 6 and the second bevel gear 7 are meshed. A small pulley 33 is rotatably installed at the bottom inside the box body 1, and a second belt 32 is sleeved between the large pulley 36 and the small pulley 33. The hypotenuse surfaces of the second belt 32 both pass through the corresponding side surfaces of the box body 1. An L-shaped plate 35 is fixedly installed at the bottom of the placing plate 5. A chute 28 is opened at the bottom inside the box body 1, and a slider 29 is slidably installed inside the chute 28. A vertical plate 27 is vertically and fixedly installed at the top of the slider 29. A second stopper 34 is hinged to the top end of the side surface of the vertical plate 27 through an elastic one-way hinge. A fourth spring rod 30 fixed to the side surface of the slider 29 is horizontally and fixedly installed at the inner end of the chute 28. A fifth spring rod 31 is horizontally and fixedly installed at the top of the small pulley 33;

[0037] Preferably, when the vertical plate 27 moves to drive the second stopper 34 to move, the second stopper 34 no longer blocks the L-shaped plate 35. At this time, the pulling force generated by the first spring rod 18 will cause the placing plate 5 to move downward, and the downward movement of the placing plate 5 will drive the connection assembly and the photovoltaic panel 2 to move downward into the box body 1.

[0038] Please refer to the appendix Figure 1 - appendix Figure 5 , in a preferred embodiment, the plugging assembly includes: a sliding cover 3. The sliding cover 3 is horizontally slidably arranged on the top of the box body 1. Two symmetrically arranged second spring rods 19 are horizontally fixed on the side of the box body 1, and the telescopic ends of the two second spring rods 19 are fixedly installed at the bottom of the sliding cover 3. A first stopper 25 is hinged to the bottom of the sliding cover 3 through an elastic one-way hinge, and an opening groove 26 adapted to the first stopper 25 is opened at the top of the side of the box body 1. A U-shaped plate 20 is arranged on the side of the box body 1. A third spring rod 21 is vertically installed at the bottom of the box body 1, and the telescopic end of the third spring rod 21 is fixedly installed at the top of the horizontal side of the U-shaped plate 20. The corresponding vertical side of the U-shaped plate 20 passes through the bottom of the box body 1;

[0039] Furthermore, the vertical side of the U-shaped plate 20 will no longer block the entry of the first stopper 25. Furthermore, the pulling force generated by the second spring rod 19 will cause the sliding cover 3 to move back to its original position.

[0040] Please refer to the attached Figure 1 - attachment Figure 6 , in a preferred embodiment, the connecting component includes: a connecting plate 24, the connecting plate 24 is vertically and fixedly installed on the top of the placing plate 5, and the top end of the connecting plate 24 is rotatably installed at the bottom of the photovoltaic panel 2. A slideway 22 is fixed at the bottom of the photovoltaic panel 2, and a movable block is slidably installed inside the slideway 22. An electric telescopic rod 23 is vertically and fixedly installed on the top of the placing plate 5, and the output end of the electric telescopic rod 23 is rotatably installed at the bottom of the movable block;

[0041] Specifically, the electric telescopic rod 23 drives the movable block to move, the movement of the movable block drives the slideway 22 to move, and the movement of the slideway 22 will change the angle of the photovoltaic panel 2 to achieve the adjustment of the photovoltaic panel 2.

[0042] The working principle of the present invention: When using the photovoltaic panel 2, first move the sliding cover 3 to make the second spring rod 19 generate a pulling force. In addition, at this time, the first stopper 25 will cross the vertical side of the U-shaped plate 20 under the influence of the elastic one-way hinge. When the second spring rod 19 generates a pulling force to make the first stopper 25 move back, it will be blocked by the vertical side of the U-shaped plate 20 to achieve the opening of the sliding cover 3;

[0043] Then lift the placing plate 5 through the handle. The upward movement of the placing plate 5 drives the L-shaped plate 35 to move upward and makes the first spring rod 18 generate a pulling force. Similarly, it can be known that the horizontal side of the L-shaped plate 35 will be blocked by the second stopper 34 after crossing the second stopper 34 to move the photovoltaic panel 2 out of the box body 1;

[0044] When using the photovoltaic panel 2, the electric telescopic rod 23 can drive the movable block to move, the movement of the movable block drives the slideway 22 to move, and the movement of the slideway 22 will change the angle of the photovoltaic panel 2 to achieve the adjustment of the photovoltaic panel 2;

[0045] When there is strong wind, the strong wind will blow the wind vane 17. During this period, the horizontal rotation of the wind vane 17 will drive the cross bar 16, the vertical bar 15 and the turntable 14 to rotate. The rotation of the vertical bar 15 drives the second bevel gear 7 to rotate through the U-shaped bar 11, so that the fan blade 13 faces the wind direction, then the fan blade 13 will rotate. The rotation of the fan blade 13 drives the sleeve 12 to rotate, the rotation of the sleeve 12 drives the second pulley 10 to rotate, the rotation of the second pulley 10 drives the first belt 8 to rotate, the rotation of the first belt 8 drives the first pulley 9 to rotate, the rotation of the first pulley 9 drives the second bevel gear 7 to rotate, the rotation of the second bevel gear 7 drives the first bevel gear 6 to rotate, the rotation of the first bevel gear 6 drives the rotating rod 4 to rotate, the rotation of the rotating rod 4 drives the large pulley 36 to rotate, the rotation of the large pulley 36 drives the second belt 32 to rotate, the second belt 32 drives the small pulley 33 to rotate at an accelerated speed. The accelerated rotation of the small pulley 33 will drive the fifth spring rod 31 to rotate. Due to the action of centrifugal force, the telescopic end of the fifth spring rod 31 moves away from the small pulley 33, so that the fifth spring rod 31 becomes longer. Then when the external wind force is large, the telescopic end of the fifth spring rod 31 will contact the vertical plate 27 and drive the vertical plate 27 to move and make the fourth spring rod 30 generate elastic force. The movement of the vertical plate 27 drives the second stopper 34 to move, then the second stopper 34 no longer blocks the L-shaped plate 35. At this time, the pulling force generated by the first spring rod 18 will make the placement plate 5 move downward. The downward movement of the placement plate 5 will drive the connection assembly and the photovoltaic panel 2 to move downward into the box body 1. When the photovoltaic panel 2 completely enters the box body 1, the placement plate 5 will contact the top of the corresponding vertical side of the U-shaped plate 20 and make the U-shaped plate 20 move downward, then the vertical side of the U-shaped plate 20 will also no longer block the first stopper 25 from entering. Further, the pulling force generated by the second spring rod 19 will make the sliding cover 3 move back to its original position. If the external wind force is small, the centrifugal force received by the fifth spring rod 31 is small, then the telescopic end of the fifth spring rod 31 will not contact the vertical plate 27;

[0046] In summary, the photovoltaic panel 2 can be automatically protected in strong wind weather, thereby improving the safety of the photovoltaic panel 2 during use.

[0047] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
