[0013] Another technical solution provided by the present invention is a method for installing a photovoltaic support in a mountainous area suitable for complex terrain, comprising the following steps: Step 1: When using, first place the fixing base on the concrete pier, and place the two clamps on both sides of the concrete pier. Then, adjust the direction of the fixing plate by rotating the connecting base and the fixing base. After roughly determining the direction of the fixing plate, fix the two clamps to the concrete pier; Step 2: The ratchet is driven to rotate by the tool and the polygonal groove. The ratchet rotates and causes the ratchet teeth to swing. The drive shaft and the torsion spring cause the ratchet teeth to immediately contact the ratchet after swinging, thereby achieving unidirectional rotation of the ratchet. Step 3: During the rotation process, the ratchet reels the first steel cable through the rotating shaft, thereby cooperating with the fixing block to keep the connection seat and the clamp fixed.

As a result, during the downward movement of the transmission ring, the fixed ring is driven to move toward the limit block and come into conflict with the limit block. Step 6: After the fixing ring contacts the limiting block, as the fixing ring continues to descend, it drives the second steel cable to move, and then the fixing plate begins to tilt. During this process, due to the action of the piston, the air pressure on the piston side of the sleeve continues to decrease, thereby achieving the tension of the fixing plate. The deflection angle of the fixing plate can be adjusted by adjusting the position of the transmission ring; Step 7: Install the photovoltaic panel on the photovoltaic bracket light fixing plate.

Finally, the rotation angle of the photovoltaic panel can be adjusted through the action of the installation assembly. In the entire adjustment process, only a small tool such as a hexagonal wrench is required, thereby reducing the difficulty of installing photovoltaic panels on complex mountainous areas.

[0021] By rotating the connecting base 2 and the fixing base 1, the support column 10 can be rotated to adjust the direction of the photovoltaic panel; By adjusting the assembly, the height of the support plate 22 can be adjusted, thereby achieving the height adjustment work of the photovoltaic panel; Finally, the rotation angle of the photovoltaic panel can be adjusted by installing the components, and during the entire adjustment process, only a small tool such as a hexagonal wrench is needed, thus reducing the difficulty of installing photovoltaic panels on complex mountainous areas.

Through the action of the transmission shaft 32 and the torsion spring 31, the ratchet teeth 34 immediately contact the ratchet 33 after swinging, thereby realizing the unidirectional rotation of the ratchet 33. During the rotation process, the ratchet 33 reels the first steel cable 9 through the rotating shaft 7, and then cooperates with the fixing block 3, so that the connecting seat 2 and the clamp 4 remain fixed. By adjusting the rotation angle of each ratchet 33 multiple times, the connecting seat 2 can be fixed in position to determine the orientation of the fixing plate 21.

[0027] Furthermore, the adjustment component includes: A first gear 12 is rotatably disposed on the top of the connecting base 2; The second gear 29 is rotatably disposed on the top of the connecting base 2, and the second gear 29 and the first gear 12 are meshed with each other; The screw rod 30 is fixed to the second gear 29 , and a threaded hole is provided at the bottom of the support plate 22 , and the screw rod 30 is located in the threaded hole.

[0028] The first gear 12 is driven to rotate by a tool. During the rotation, the first gear 12 drives the screw rod 30 to rotate through the second gear 29, and cooperates with the threaded hole on the support plate 22 to make the support plate 22 rise along the support column 10, thereby adjusting the height of the fixed plate 21.

[0029] Furthermore, the installation components include: A second connecting block 25, the second connecting block 25 is rotatably connected to the support plate 22; A fixing plate 21, the fixing plate 21 is fixed to the second connecting block 25; A limiting assembly, wherein the limiting assembly is rotatably connected to the support plate 22 and the limiting assembly is rotatably connected to the fixing plate 21; The tensioning assembly is fixed to the fixing plate 21 , and the tensioning assembly is connected to the supporting column 10 .

[0032] Through the cooperation of the rod body 17 and the circular groove 16, the transmission ring 15 is driven to rotate by the rod body 17. During the rotation, the transmission ring 15 moves downward along the support column 10 through the internal threaded protrusion and the threaded groove 11, and adjusts its position on the second steel cable 13, so that during the downward movement of the transmission ring 15, the fixed ring 18 is driven to move toward the limiting block 14 and conflicts with the limiting block 14. When the fixing ring 18 conflicts with the limiting block 14, as the fixing ring 18 continues to descend, the fixing ring 18 presses down the limiting block 14 to drive the second steel cable 13 to move, so that the fixed plate 21 begins to tilt. During this process, due to the action of the piston 28, the air pressure on the side of the piston 28 in the sleeve 24 is continuously reduced, thereby achieving the tensioning of the fixed plate 21. The deflection angle of the fixed plate 21 can be adjusted by adjusting the position of the transmission ring 15.

[0033] Another aspect of the present invention provides a method for installing a photovoltaic support in a mountainous area suitable for complex terrain, comprising the following steps: Step 1: When using, first place the fixing base 1 on the cement pier, and place the two clamps 4 on both sides of the cement pier. Then, adjust the direction of the fixing plate 21 by rotating the connecting base 2 and the fixing base 1. After roughly determining the direction of the fixing plate 21, fix the two clamps 4 to the cement pier; Step 2: The ratchet 33 is driven to rotate by the tool and the polygonal groove. During the rotation of the ratchet 33, the ratchet teeth 34 are driven to swing. Through the action of the transmission shaft 32 and the torsion spring 31, the ratchet teeth 34 immediately come into contact with the ratchet 33 after swinging, thereby achieving unidirectional rotation of the ratchet 33. Step 3: During the rotation process, the ratchet 33 reels the first steel cable 9 via the rotating shaft 7, thereby cooperating with the fixing block 3 to keep the connection base 2 and the clamp 4 fixed. The rotation angle of each ratchet 33 is adjusted multiple times to achieve the fixed position of the connection base 2 and determine the direction of the fixing plate 21; Step 4: Then, the first gear 12 is driven to rotate by a tool. During the rotation process, the first gear 12 drives the screw rod 30 to rotate through the second gear 29, and cooperates with the threaded hole on the support plate 22, so that the support plate 22 rises along the support column 10, thereby adjusting the height of the fixed plate 21; Step 5: Then, the rod 17 and the circular groove 16 cooperate to drive the transmission ring 15 to rotate. During the rotation process, the transmission ring 15 moves downward along the support column 10 through the internal threaded protrusion and the threaded groove 11, and adjusts its position on the second steel cable 13. As a result, during the downward movement of the transmission ring 15, the fixing ring 18 is driven to move toward the limiting block 14 and come into contact with the limiting block 14. Step 6: After the fixing ring 18 contacts the limiting block 14, as the fixing ring 18 continues to descend, it drives the second steel cable 13 to move, thereby causing the fixing plate 21 to begin to tilt. During this process, due to the action of the piston 28, the air pressure on the side of the piston 28 in the sleeve 24 is continuously reduced, thereby achieving the tensioning of the fixing plate 21. The deflection angle of the fixing plate 21 can be adjusted by adjusting the position of the transmission ring 15; Step 7: Install the photovoltaic panel on the photovoltaic bracket light fixing plate 21.
