[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention accommodates the elastically arranged adjusting rod into the interior of the supporting rod through the cooperation of the elastically arranged second fixing block and the second fixing groove. When in use, it is necessary to adjust the length of the adjusting rod extending from the interior of the supporting rod. When the extending length of the adjusting rod is adjusted, the height and level of the supporting frame can be adjusted synchronously. After the adjustment is completed, the fixing bolt on the fixing gasket is pressed down to fix the adjusting rod by fixing the fixing bolt. When the fixing bolt is fixed, the second limiting block on the fixing bolt will press down the fourth airbag. At this time, the internal gas of the fourth airbag is discharged to the interior of the third airbag through the second exhaust pipe.

[0024] 3. The photovoltaic panel body will generate a certain amount of heat when working, and the opening of the heat dissipation holes can realize the heat dissipation treatment of the bottom of the photovoltaic panel body. In order to prevent debris from clogging the heat dissipation holes, a slidable connecting plate is set on one side of the heat dissipation hole. When the photovoltaic panel body is in use, the fixing frame will be flipped to the inside of the support frame. When flipping, the elastically set extrusion plate will be supported by the inner wall of the support frame. During the supporting process, the first airbag is squeezed, and the gas inside the first airbag is discharged to the inside of the second airbag through the first exhaust pipe. When the second airbag expands, it will push the connecting plate to move along the heat dissipation hole. When the connecting plate moves along the heat dissipation hole, the scraper on the connecting plate can clean the debris adhering to the inside of the heat dissipation hole.

[0074] Embodiment five:

[0075] like Figure 3-Figure 6 As shown, the installation method of the adjustable roof photovoltaic support structure disclosed in the fifth embodiment of the present invention has a structure that is basically the same as that in the fourth embodiment, except that:

[0080] A first exhaust pipe 19 is provided between the second airbag 14 and the first airbag 12 , and the second airbag 14 is connected to the interior of the first airbag 12 through the first exhaust pipe 19 ;

[0081] After the support frame 1 is fixed, the fixing frame 2 is flipped out from the inside of the support frame 1. After flipping out, the fixing frame 2 is limited and fixed, and then the photovoltaic panel body 3 is fixed to one side of the fixing frame 2. When the photovoltaic panel body 3 is working, a certain amount of heat will be generated, and the opening of the heat dissipation hole 8 can realize the heat dissipation treatment of the bottom of the photovoltaic panel body 3. At the same time, in order to prevent debris from clogging the heat dissipation hole 8, a slidable connecting plate 9 is provided on one side of the heat dissipation hole 8. When the photovoltaic panel body 3 is in use, the fixing frame 2 will be flipped to the inside of the support frame 1. When flipping, the elastically arranged extrusion plate 10 will be supported by the inner wall of the support frame 1. During the supporting process, the first airbag 12 is squeezed, and the internal gas of the first airbag 12 is discharged to the inside of the second airbag 14 through the first exhaust pipe 19. When the second airbag 14 expands, it will push the connecting plate 9 to move along the heat dissipation hole 8. When the connecting plate 9 moves along the heat dissipation hole 8, the scraper 18 on the connecting plate 9 can clean up the debris adhering to the inside of the heat dissipation hole 8.

[0082] The present scheme is specifically as follows: the support frame 1 is transported to the designated position, and then the extrusion block 53 is squeezed inwardly, and the extrusion block 53 squeezes the fifth airbag 52 on one side of the extrusion block 53, and the internal gas of the fifth airbag 52 is discharged to the inside of the sixth airbag 55 through the third exhaust pipe 54, and the sixth airbag 55 expands and pushes the abutting block 25 to move to one side. During the movement, the abutting block 25 squeezes the abutting rod 27 outwardly through the cooperation of the oblique groove 57, and the abutting rod 27 then squeezes the elastically arranged first fixing block 32 outwardly. When the first fixing block 32 is pushed out of the first fixing groove 28 by the abutting rod 27, the support rod 6 can be rotated to be perpendicular to the first giving way groove 5, and when rotating, the force acting on the extrusion block 53 can be cancelled. At this time, the abutting rod 27 is reset under the action of the fourth reset spring 30, and after the support rod 6 is rotated to 90°, the elastically arranged first fixing block 32 will be inserted into the inside of another group of first fixing grooves 28, completing the angle fixation of the support rod 6.

[0083] At the same time, when the first fixing block 32 is abutted by the abutting rod 27, the first fixing block 32 will be retracted into the inside of the third receiving groove 33. At this time, the moving first fixing block 32 will drive the second fixing block 39 to move through the first pull rope 36. When the second fixing block 39 is moved out of the second fixing groove 40, the adjusting rod 21 pops out from the inside of the support rod 6 under the action of the third return spring 22. When the length of the adjusting rod 21 extending from the inside of the support rod 6 is adjusted, the height and level of the support frame 1 can be adjusted. After the adjustment is completed, the fixing bolt 47 on the fixing gasket 7 is pressed down to fix the adjusting rod 21 by fixing the fixing bolt 47. When the fixing bolt 47 is fixed, the second limiting block 50 on the fixing bolt 47 will press down the fourth airbag 49. At this time, the internal gas of the fourth airbag 49 is discharged to the inside of the third airbag 44 through the second exhaust pipe 46. The third airbag 44 expands and pushes the third fixing block 43 to be inserted into the inside of one group of adjusting grooves 41, thereby completing the fixing of the adjusting rod 21 and the support rod 6, and then fixing the height of the support frame 1.

[0084] After the support frame 1 is fixed, the fixing frame 2 is flipped out from the inside of the support frame 1. After flipping out, the fixing frame 2 is limited and fixed, and then the photovoltaic panel body 3 is fixed to one side of the fixing frame 2. When the photovoltaic panel body 3 is working, a certain amount of heat will be generated, and the opening of the heat dissipation hole 8 can realize heat dissipation treatment at the bottom of the photovoltaic panel body 3. At the same time, in order to prevent debris from clogging the heat dissipation hole 8, a slidable connecting plate 9 is provided on one side of the heat dissipation hole 8. When the photovoltaic panel body 3 is in use, the fixing frame 2 will be flipped to the inside of the support frame 1. During the flipping, the elastically arranged extrusion plate 10 will be abutted by the inner wall of the support frame 1. During the abutting process, the first airbag 12 is squeezed, and the internal gas of the first airbag 12 is discharged to the inside of the second airbag 14 through the first exhaust pipe 19. When the second airbag 14 expands, it will push the connecting plate 9 to move along the heat dissipation hole 8. When the connecting plate 9 moves along the heat dissipation hole 8, the scraper 18 on the connecting plate 9 can clean up the debris adhering to the inside of the heat dissipation hole 8.

[0085] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
