Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a stepped photovoltaic bracket. Background Technique

[0002] According to the application number "CN202220703000.8", by setting an adjusting mechanism, while the slope body cooperates with the fixing pile and the fixing column to fix the fixing seat, the fixing seat cooperates with the rotating block and the U-shaped block to fix the first support block, so as to facilitate the installation of the photovoltaic bracket. Also, while the second support rod cooperates with the first fixing block and the fixed shaft rod to fix the rotating head, the rotating head cooperates with the first bearing and the rotating seat to fix the threaded rod. And the fixing seat cooperates with the support cylinder and the second bearing to fix the rotating seat, so as to adjust the angle of the bracket. When adjusting the angle, by rotating the threaded rod, the threaded rod drives the second support rod and the first support block to rotate through the first bearing, the rotating head, the fixed shaft rod and the first fixing block, and the first support block rotates through the U-shaped block and the rotating block, so as to adjust the angle. The fixing pile is inserted into the slope body, and by rotating the fixing column, the height of the bracket can be adjusted, effectively facilitating the installation of the bracket on the slope;

[0003] By rotating the rotating fixing rods on the first support rod and the second support rod and then fixing the two rotating fixing rods with screws, the role of forming a support frame is achieved. Also, while the connecting frame cooperates with the limiting plate to fix the photovoltaic panel, the two connecting frames cooperate to achieve the fixed connection of multiple brackets.

[0004] The inventor found the following problems in the prior art that were not well solved during the implementation of this solution: It is generally divided into two parts. One is the fixing part, and the other is the installation part. The fixing part is the fixing pile and the fixing column; the installation part is the connection structure of how the upper part of the fixing column is connected to the photovoltaic panel;

[0005] The fixing pile is inserted deep into the slope body, and the fixing column is inserted into the fixing pile and limited and fixed and the height is adjusted by means of threaded connection. When implementing this technical solution, the following situations will be encountered:

[0006] For outdoor use, due to wind weather problems, the photovoltaic panel shakes. The wind resistance of the photovoltaic panel is large, and it will shake together with the fixing column. In addition to the threaded connection between the fixing column and the fixing pile, there is no other limiting mechanism. Therefore, the shaking will cause the fixing column to become loose, resulting in changes in the height and direction of the fixed photovoltaic panel;

[0007] Since stepped photovoltaic brackets are mostly installed on slopes, and the slopes are mostly of soil structure, the scouring of rainwater will cause different inclination angles of the slopes. Therefore, in the later stage, the fixing columns need to be rotated so that the height of the photovoltaic panels can be coordinated with the inclination of the slopes to achieve a more stable use environment for the photovoltaic panels. However, when used outdoors and eroded by rainwater, the threaded connections between the two are prone to rust. After rusting, it is very difficult to rotate, and the component cannot be used anymore, resulting in problems of easy rusting and high cost. Summary of the Invention

[0008] The main purpose of the present utility model is to provide a stepped photovoltaic bracket, which can effectively solve the problems in the background technology.

[0009] To achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0010] A stepped photovoltaic bracket includes a conical pipe fitting. A connecting cylinder is arranged at the top of the conical pipe fitting. An extension rod is inserted through the connecting cylinder, and one end of the extension rod passing through the connecting cylinder is inserted into the interior of the conical pipe fitting. A plurality of rod holes are equidistantly drilled on the side wall of the extension rod.

[0011] The connecting cylinder includes a top cylinder. Inner ring grooves one are drilled at both the top and bottom of the inner wall of the top cylinder. Sealing rings one are embedded in the inner ring grooves one. Through holes are drilled on both side walls of the top cylinder between the inner ring grooves one. A positioning pin is arranged between the through holes. External screw teeth two are arranged at both ends of the positioning pin. Side cylinders are fixed on both outer walls of the top cylinder. Nuts are embedded in the side cylinders. External screw teeth one are arranged on the outer walls of the side cylinders away from the top cylinder. Inner threaded cylinders are sleeved on the outer walls of the side cylinders at the positions of the external screw teeth one. Inner ring grooves two are drilled on the inner side walls of the inner threaded cylinders close to the top cylinder. Sealing rings two are arranged in the inner ring grooves two.

[0012] Preferably, the side cylinders communicate with the through holes respectively, and both ends of the positioning pin pass through the through holes and are respectively inserted into the side cylinders at the positions with matching positions.

[0022] The internal threaded barrel is sleeved on the outer wall of the side barrel and is threadedly connected thereto. The end of the internal threaded barrel has strong sealing performance, which prevents erosion caused by rainwater from entering and causing difficulty in removing the nut in the later stage.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] like Figures 1-4As shown in the figure, a stepped photovoltaic bracket includes a conical pipe fitting 1. A connecting cylinder 3 is arranged at the top of the conical pipe fitting 1. An extension rod 2 is inserted through the connecting cylinder 3. One end of the extension rod 2 passing through the connecting cylinder 3 is inserted into the interior of the conical pipe fitting 1. A number of rod holes 21 are equidistantly drilled on the side wall of the extension rod 2.

[0030] The connecting cylinder 3 includes a top cylinder 31. Inner ring grooves 311 are drilled at both the top and bottom of the inner wall of the top cylinder 31. Sealing rings 312 are embedded in the inner ring grooves 311. Perforations 313 are drilled on both side walls of the top cylinder 31 between the inner ring grooves 311. A positioning pin 33 is arranged between the perforations 313. External helical teeth 331 are arranged at both ends of the positioning pin 33. Side cylinders 32 are fixed on both outer walls of the top cylinder 31. Nuts 34 are embedded in the side cylinders 32. External helical teeth 321 are arranged on the outer walls of the side cylinders 32 away from the top cylinder 31. Internal threaded cylinders 35 are sleeved on the outer walls of the side cylinders 32 at the positions of the external helical teeth 321. Inner ring grooves 351 are drilled on the inner side walls of the internal threaded cylinders 35 close to the top cylinder 31. Sealing rings 352 are arranged in the inner ring grooves 351.

[0031] Specifically, the side cylinders 32 communicate with the perforations 313 respectively. Both ends of the positioning pin 33 pass through the perforations 313 and are respectively inserted into the side cylinders 32 with matching positions. One end of the positioning pin 33 located inside the top cylinder 31 communicates with the rod hole 21 with a matching position, playing a role in positioning the extension rod 2.

[0032] Specifically, the ends of the positioning pin 33 inserted into the side cylinders 32 are respectively threadedly connected with the nuts 34 through the external helical teeth 331, making the penetration of the positioning pin 33 and the rod hole 21 more stable.

[0033] Specifically, the side cylinders 32 are respectively threadedly connected with the ends of the internal threaded cylinders 35 away from the sealing rings 352 through the external helical teeth 321. The outer walls of the extension rod 2 are respectively in contact with the inner walls of the sealing rings 312. The inner walls of the sealing rings 352 are respectively in contact with the outer walls of the side cylinders 32 away from the external helical teeth 321, ensuring the sealing performance after the connection between the side cylinders 32 and the internal threaded cylinders 35.

[0034] Working principle: Insert the conical pipe fitting 1 into the slope. The extension rod 2 passes through the two sealing rings 312 of the connecting cylinder 3 and then inserts into the inside of the conical pipe fitting 1. The positioning pin 33 passes through one of the side cylinders 32. The positioning pin 33 is located in the top cylinder 31 and passes through the rod hole 21 with a matching height, forming the basic positioning of the end seal. Subsequently, place the nut 34 in the side cylinder 32 and thread it with the external thread teeth two 331 at the end of the positioning pin 33 to form secondary limitation to avoid the problem of the positioning pin 33 coming off. Then, sleeved the internal thread cylinder 35 outside the side cylinder 32 and thread it with the external thread teeth one 321. At this time, the inner ring groove two 351 will contact the outer wall of the side cylinder 32 away from the external thread teeth one 321 to form a sealing protection, ensuring that rainwater will not erode the external thread teeth one 321 and cause the situation of not being able to open.
