[0001] The utility model belongs to the technical field of photovoltaic new energy, and particularly relates to a photovoltaic bracket with adjustable inclination angle. Background Technique

[0002] Photovoltaic generally refers to a photovoltaic power generation system. Abbreviated as PV, it refers to a power generation system that directly converts solar radiant energy into electrical energy by using the photovoltaic effect of photovoltaic cells. With the development and utilization of environmental protection new energy, the application of photovoltaic power generation systems is becoming more and more extensive.

[0003] When installing and using a photovoltaic panel, a photovoltaic bracket is required. However, most of the existing photovoltaic brackets are designed with a fixed inclination angle, that is, the installation angle is fixed and cannot be adaptively adjusted according to the optimal light conversion angle at different locations, resulting in certain limitations in use. Therefore, we propose a photovoltaic bracket with adjustable inclination angle. Content of the Utility Model

[0004] The purpose of the utility model is to provide a photovoltaic bracket with adjustable inclination angle to solve the problem that most of the existing photovoltaic brackets are designed with a fixed inclination angle, that is, the installation angle is fixed and cannot be adaptively adjusted according to the optimal light conversion angle at different locations, resulting in certain limitations in use as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A photovoltaic bracket with adjustable inclination angle, including a bracket body. The bracket body includes two side brackets. Each side bracket includes two fixed bases. A number of fixing bolts are threadedly installed on the fixed bases. The upper surface of one of the fixed bases is fixedly installed with a front leg, and the upper surface of the other fixed base is provided with a rear leg. The rear leg includes an outer cylinder fixedly installed on the upper surface of the corresponding fixed base. The inner wall of the top end of the outer cylinder is slidably installed with an inner sleeve plate. A groove is formed on the bottom side of the inner sleeve plate and a positioning post is movably arranged in the groove. A number of positioning holes for the positioning post to be inserted into are formed on the outer cylinder. The top ends of the front leg and the inner sleeve plate are both rotatably installed with rotating seats. The same cross arm one is fixedly installed between the two rotating seats. A number of cross arms two are movably arranged between the two cross arms one. Assembly bolts are threadedly installed at both ends of the cross arm two.

Specific embodiments

[0028] Please refer to Figure 1-7 , the present utility model provides a photovoltaic bracket with adjustable inclination angle, including a support body 1. The support body 1 includes two side supports 2. The side support 2 includes two fixed bases 3. A plurality of fixing bolts 4 are threadedly installed on the fixed base 3. The upper surface of one of the fixed bases 3 is fixedly installed with a front leg 5, and the upper surface of the other fixed base 3 is provided with a rear leg 6. The rear leg 6 includes an outer cylinder 7 fixedly installed on the upper surface of the corresponding fixed base 3. The inner wall of the top end of the outer cylinder 7 is slidably installed with an inner sleeve plate 8. A groove is formed in the bottom side of the inner sleeve plate 8 and a positioning column 16 is movably arranged in the groove. A plurality of positioning holes for the positioning column 16 to be inserted into are formed in the outer cylinder 7. The top ends of the front leg 5 and the inner sleeve plate 8 are both rotatably installed with a rotating seat 9. The same cross arm one 10 is fixedly installed between the two rotating seats 9. A plurality of cross arms two 11 are movably arranged between the two cross arms one 10. Assembly bolts 12 are threadedly installed at both ends of the cross arm two 11. A plurality of assembly threaded grooves for the assembly bolts 12 to be screwed into are formed in the cross arm one 10. Two strip-shaped channels are formed in the cross arm two 11, and a plurality of installation bolts 13 are passed through the strip-shaped channels. The tail end of the installation bolt 13 passes through the strip-shaped channel and is threadedly installed with an installation nut 21.

[0029] By setting the front leg 5 and the rear leg 6 to cooperate with the cross arm one 10 and the cross arm two 11, the outer cylinder 7 and the inner sleeve plate 8 are assembled to form the front leg 5 and the inner sleeve plate 8 can slide up and down. Therefore, the inclination angle of the cross arm one 10 can be adjusted by using the rotating seat 9, and then the angle of the cross arm two 11 can be adjusted, so that it can be adaptively adjusted according to the needs of the best light conversion angle, improving the universality of use, and the operation adjustment is convenient. By setting the cross arm two 11 to cooperate with the assembly bolts 12, the cross arm two 11 can be adjusted in position on the cross arm one 10, which is suitable for the installation of photovoltaic panels of different specifications. And by using the installation bolt 13 to cooperate with the limit gasket ring 19, the position of the installation bolt 13 can be restricted to prevent the installation bolt 13 from shifting in the strip-shaped channel, thereby improving the installation stability of the photovoltaic panel.

[0030] A first limiting slider 14 is fixedly installed on the bottom side surface of the inner sleeve plate 8, and a first limiting slideway for the first limiting slider 14 to slide is formed on the side surface of the outer cylinder body 7. The first limiting slider 14 slides in the first limiting slideway, which can support the up and down movement process of the inner sleeve plate 8, improve the movement smoothness, and can prevent the inner sleeve plate 8 from sliding upwards and detaching from the outer cylinder body 7, playing a limiting role.

[0031] A spring 15 is fixedly installed on the inner wall of the bottom groove of the inner sleeve plate 8. The spring 15 is fixedly connected with the positioning column 16. A telescopic rod is arranged inside the spring 15. The telescopic rod is fixed on the inner wall of the groove and is fixedly connected with the positioning column 16. When the positioning column 16 disengages from the positioning hole, the spring 15 will be compressed and deformed. Therefore, after adjusting the position, the elasticity of the spring 15 can be used to drive the positioning column 16 to reset and insert into the positioning hole to achieve convenient locking. The setting of the telescopic rod can support the positioning column 16 and prevent the positioning column 16 from shaking.

[0032] Two side baffles 17 are fixedly installed at both ends of the second cross arm 11. The two side baffles 17 at the same side position are respectively attached to both side surfaces of the first cross arm 10. A second limiting slider 18 is fixedly installed on the side surface of the side baffle 17. A second limiting slideway for the second limiting slider 18 to slide is formed on the side surface of the first cross arm 10.

By using the limiting gasket 19 in cooperation with the limiting block 20, the position of the mounting bolt 13 can be restricted, and the phenomenon that the mounting bolt 13 deviates in the strip-shaped channel can be prevented, improving the use stability.

[0034] Sealing plates 23 are respectively attached to both ends of the first cross arm 10. Alignment inserting plates 22 are fixedly installed at both ends of the first cross arm 10. Alignment inserting holes for the alignment inserting plates 22 to be inserted into are formed on the sealing plates 23. A pin 24 is inserted between the alignment inserting plates 22 and the sealing plates 23. The sealing plates 23 can block the second limiting slideway, and can prevent the second cross arm 11 from detaching from the first cross arm 10 during the sliding adjustment. And the pin 24 is used in cooperation with the alignment inserting plates 22, which is convenient for removing the sealing plates 23 during disassembly and assembly.

[0035] During use, when adjusting the inclination angle, press the positioning post 16 so that the positioning post 16 squeezes the spring 15 to deform and disengages from the positioning hole. At this time, the inner sleeve plate 8 is unlocked and can slide up and down. When sliding, cooperate with the rotating seat 9 to realize the angle adjustment of the first cross arm 10. After sliding to the appropriate position, the elasticity of the spring 15 will drive the positioning post 16 to snap into the positioning hole to achieve position locking, reaching the inclination angle adjustment. Then, use the fixing bolt 4 to fixedly install the fixed base 3, and adjust the position of the second cross arm 11 according to the specifications of the photovoltaic panel.
