Description

Technical Field

[0001] The utility model relates to the technical field of flexible photovoltaic panel brackets, and in particular to a flexible bracket reinforcement structure. Background Art

[0002] Photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. Compared with traditional photovoltaic brackets, flexible photovoltaic brackets are composed of bracket columns and steel strands, which support photovoltaic modules.

[0003] Since the slope of each place may be different due to the ups and downs of the mountains, the installation angle of the steel strands varies greatly. If the angle between the steel strands and the horizontal plane is too large, it will cause excessive compression or pull-out force, which will cause the support to be damaged or tipped over. Therefore, installing multiple struts can increase the strength of the support. However, in the prior art, each strut requires a separate foundation construction, which has high foundation construction costs and occupies a lot of land.

[0004] The Chinese invention patent with authorization announcement number CN114977994A: A flexible photovoltaic bracket and photovoltaic system discloses a technical solution including a support member and a plurality of rope members; each group of rope members includes two rope bodies, a plurality of first cables, a plurality of second cables, a first adjustment member and a plurality of second adjustment members. This solution has the beneficial effect of greatly improving the overall structural stiffness of the photovoltaic bracket by adjusting the pre-tightening force of the rope body.

[0005] Although the above utility model patent has a technical solution that can improve the overall structural stiffness of the flexible photovoltaic bracket, it cannot solve the technical problems in the prior art that each support pole requires a separate foundation construction, the foundation construction cost is high, and the land occupation is large. Therefore, the field urgently needs a flexible bracket reinforcement structure to solve the problems existing in the prior art. Utility Model Content

[0006] The utility model aims to provide a flexible support reinforcement structure to solve the technical problem in the prior art that each support rod needs to have a separate foundation construction and the foundation construction cost is high.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flexible bracket reinforcement structure, including a first grounding pile connected and fixed to the ground, a column fixedly installed on the first grounding pile, a crossbeam fixedly installed on the top of the column, a steel strand whose end is connected and fixed to the crossbeam, and also includes a support rod assembly, a rotating connection assembly, and a clamping connection assembly.

[0008] The support rod assembly includes a second grounding pile and a support rod; the support rod includes a first support rod and a second support rod; one end of the beam is rotatably connected to the first support rod by a rotating connection assembly, and the end of the beam away from the first support rod is rotatably connected to the second support rod by a rotating connection assembly.

[0009] The second grounding pile is connected and fixed with the free end of the first support rod and the free end of the second support rod by using a clamping connection component.

[0010] The rotating connection assembly includes a rotating slot hole that runs horizontally through the end of the beam, a rotating shaft that is rotatably installed in the rotating slot hole, a first connecting piece fixedly installed at one end of the rotating shaft close to the support rod, and a limiting member is installed at one end of the rotating shaft away from the support rod; a second connecting piece is installed at one end of the first connecting piece away from the rotating shaft by bolt connection, and the second connecting piece is fixedly connected to the first support rod at one end away from the first connecting piece.

[0011] As a preferred solution, the limiting member is a nut that cooperates with the rotating shaft thread.

[0012] By adopting the above technical solution, before the photovoltaic panel support is installed, the first support rod can rotate about the rotating shaft or the bolt, thereby improving the flexibility of the installation operation.

[0013] The clamping connection assembly includes a lower slot clamping piece connected to the first support rod bolt, an upper slot clamping piece connected to the second support rod bolt, and a first connection plate fixedly connected to the top surface of the second grounding pile. The bottom end of the upper slot clamping piece is fixedly connected to the first connection plate. A first clamping groove is vertically opened at the top of the upper slot clamping piece, and a second clamping groove is vertically opened at the bottom end of the lower slot clamping piece. The upper slot clamping piece and the lower slot clamping piece are clamped to each other by using the first clamping groove and the second clamping groove. After the clamping is completed, the first clamping groove is close to the side wall of the lower slot clamping piece, and the second clamping groove is close to the side wall of the upper slot clamping piece.

[0014] As a necessary technical solution, the slot width of the first clamping slot is greater than the thickness of the lower slot clamping piece, and the slot width of the second clamping slot is greater than the thickness of the upper slot clamping piece, so that after the lower slot clamping piece and the upper slot clamping piece are clamped together, the lower slot clamping piece can be twisted horizontally to change the angle between the side wall of the lower slot clamping piece and the side wall of the upper slot clamping piece, so as to increase the tolerance range of installation errors of various parts of the bracket.

[0015] As a preferred solution, the upper notch clamping piece is welded to the first connecting plate.

[0016] It also includes a double-hole connection component, which includes a second connection plate fixedly connected to the top surface of the first grounding pile, two first ear plates fixedly installed on the upper surface of the second connection plate, the two first ear plates are arranged parallel to each other, and the first ear plate is horizontally penetrated with a first connection hole and a second connection hole, and the column is fixedly installed with a connection ear plate at one end close to the first grounding pile, the connection ear plate is inserted into the gap between the two first ear plates, and the first connection hole and the second connection hole are opened on the connection ear plate. The first rod-shaped connection member is installed through the first connection hole on the first ear plate and the first connection hole on the connection ear plate, and the second rod-shaped connection member is installed through the second connection hole on the first ear plate and the second connection hole on the connection ear plate, thereby completing the fixed installation between the column and the first grounding pile.

[0017] As a preferred solution, the first rod-shaped connecting member is a second bolt, and the second rod-shaped connecting member is a pin. When the bracket is installed on site, the column laid on the ground is first rotatably connected with the first grounding pile by using the second bolt, and then the column is rotated and erected with the second bolt as the axis, and then the pin is installed. The installation process of the pin is simple, so that there is no need for manpower to support the column for a long time, and the fixed installation between the column and the first grounding pile can be completed quickly. After the pin is installed, the second bolt is tightened.

[0018] As a preferred solution, the first connecting hole and the second connecting hole are located on the same vertical line.

[0019] As a preferred solution, the width of the gap between the two first ear plates is 0.1-1 mm greater than the thickness of the connecting ear plates, so as to stabilize the connection.

[0020] As a preferred solution, a second ear plate is fixedly connected to a side of the first ear plate away from the other first ear plate, and the bottom end of the second ear plate is fixedly connected to the second connecting plate. The second ear plate can enhance the stability of the first ear plate.

[0021] As a preferred solution, the support rod is a sleeve structure, which includes an inner sleeve and an outer sleeve sleeved outside the inner sleeve. During on-site installation, due to installation terrain factors or ground pile installation position error factors, support rods of different lengths will be required. With the sleeve structure, during installation, it is only necessary to adjust the sleeve to the required length in a telescopic manner, and then weld the outer wall of the inner sleeve to the port of the outer sleeve to obtain the required support rod length, thereby improving the flexibility of bracket installation.
