Description

Technical Field

[0001] The present application relates to the technical field of flexible photovoltaic brackets, and in particular to a reinforcement structure of a flexible bracket circular tube. Background Art

[0002] At present, flexible photovoltaic brackets have the characteristics of "large span, high clearance, long column distance, low cost, and environmental friendliness", which can effectively solve the adaptability problem of brackets in certain complex terrain scenes. Flexible photovoltaic brackets are a large-span multi-span structure, which is a prestressed steel wire rope tensioned between the two fixed points combined with a flexible bracket transverse connection system. The fixed points use a rigid structure and an outer inclined steel strand to provide support reaction force.

[0003] The flexible bracket transverse connection system is currently mainly composed of various shapes such as round tubes. The main disadvantage of the round tube transverse connection system is that the round tube is a single tube, and the flattened parts at both ends are not strong enough, so it is easy to deform or break under strong pulling. Summary of the invention

[0004] In order to solve the problem in the prior art that the flattened portion of the flexible support circular tube is not strong enough and is easily deformed or broken under strong pulling, the present application provides a reinforcement structure of the flexible support circular tube.

[0006] By adopting the above technical scheme, when the long round tube and the short round tube are connected, the short round tube and the lower shell are installed first. Initially, the limit block passes through the lower shell, and the limit block is first inserted and slid along the limit groove on the short round tube, and then the sliding component drives the limit block to slide, so that the limit block and the limit groove are tightly pressed, and the lower shell and the short round tube can be quickly installed. Then the short round tube with the reinforcement installed is sleeved inside the long round tube. When the reinforcement is installed with the long round tube, the driving component can drive the insertion rod and the slot to quickly connect, thereby realizing the positioning installation of the short round tube and the long round tube, reducing the sliding between the round tubes during the flattening process in the later stage, and also increasing the strength of the flattened part of the round tube.

[0007] Optionally, the sliding assembly includes a push rod, a skateboard and a driving disk. The skateboard and the driving disk are coaxially arranged, the skateboard is fixed to the lower shell body, the push rod slides radially relative to the skateboard, the driving disk rotates relative to the lower shell body, and the rotation axis direction of the driving disk is in the vertical direction. A rotating assembly for driving the driving disk to rotate is provided in the lower shell body, and an arc-shaped sliding hole is opened on the driving disk. One end of the push rod slides along the sliding hole, and the other end is fixed to the limit block.

[0008] By adopting the above technical solution, when the driving disk rotates relative to the lower shell, the arc-shaped sliding hole on the driving disk rotates accordingly, and the push rod is driven by the driving disk to slide back and forth along the radial direction of the slide under the limiting action of the slide, thereby achieving tight contact between the limit block and the slide groove.

[0009] Optionally, a linear slide rail is provided on the slide plate, the slide rail is arranged radially along the slide plate, and the push rod slides in the slide rail along the length direction of the slide rail.

[0011] Optionally, the rotating assembly includes a gear ring, a driving tooth, a connecting rod and a transmission tooth. An outer shell is rotatably arranged on the peripheral side of the lower shell. The outer shell is fixed to the gear ring. One end of the connecting rod is fixed to the driving tooth, and the other end is fixed to the transmission tooth. The driving tooth is meshed with the gear ring, and the transmission tooth is meshed with the drive plate.

[0012] By adopting the above technical solution, the outer shell is rotated, the outer shell drives the gear ring to rotate, the gear ring engages with the driving teeth, thereby driving the driving teeth to rotate, and the driving teeth are connected to the transmission teeth through the connecting rod, that is, the transmission teeth rotate, and the rotation of the transmission teeth can drive the driving plate to rotate.

[0013] Optionally, the driving teeth, connecting rods and transmission teeth are provided in pairs respectively, and are all axially symmetrically arranged along the center position of the driving disk.

[0016] By adopting the above technical solution, when the driving tooth rotates, it drives the rotating tooth to rotate, and the rotation of the rotating tooth drives the threaded rod to rotate. When the threaded rod rotates, it is threadedly connected with the threaded block. The threaded block is fixed to the insertion rod, and the insertion rod passes through the upper shell and the slot limiter. That is, when the upper shell and the long round tube are installed, the threaded block can be driven to move along the length direction of the threaded rod.

[0017] Optionally, an inner slide is vertically opened on the inner wall of the upper shell, and a first hole and a second hole are spaced apart on the inner slide. The first hole and the second hole are spaced apart in a direction away from the lower shell, and the second hole corresponds to the slot. The insertion rod slides back and forth along the length direction of the inner slide, and before the upper shell and the long round tube are installed, the insertion rod passes through the first hole.

[0018] By adopting the above technical solution, before the upper shell and the long round tube are installed, the insertion rod first passes through the first insertion hole. At this time, the first insertion hole forms a limit for the insertion rod, so that the insertion rod can remain stable and will not move up and down when the reinforcement and the lower shell are installed.

[0019] Optionally, a spring rod is fixed to the end of the insertion rod away from the threaded block, a rotating shaft is fixed to the spring rod, a roller is rotatably connected to the rotating shaft, and when the upper shell and the long round tube are installed, the roller rolls against the inner wall of the long round tube, and the spring rod is in a compressed state until the roller passes through the second plug hole and the slot limit.

[0020] By adopting the above technical solution, when the upper shell body is installed with the long round tube, the roller abuts against the inner wall of the long round tube and compresses the spring rod. At this time, the outer shell body is rotated so that the driving tooth drives the rotating tooth to rotate. Driven by the threaded block, the roller and the insertion rod slide along the inner slideway of the upper shell body until the insertion rod moves to the position of the second insertion hole. The spring rod restores its original length so that the roller and the slot are limited. When the outer shell body is rotated, the rotating assembly rotates at the same time, and the sliding assembly drives the limit block to abut against the slide groove of the lower shell body, thereby realizing the positioning and fixation of the reinforcement, the long round tube and the short round tube.

[0021] Optionally, the first insertion hole is provided with a beveled surface at one side edge facing the threaded rod.

[0022] By adopting the above technical solution, the edge of the first insertion hole on the side facing the threaded rod is beveled, which can save effort when the roller and the rotating shaft are recovered from the first insertion hole into the upper shell.

[0024] By adopting the above technical solution, when the roller and the rotating shaft are inserted and connected with the slot, the rotating shaft is inserted and inserted with the groove, so that the installation between the upper shell and the long round tube can be made more stable.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. When installing the reinforcement and the short round tube, first make the limit block and the slide groove on the inner wall of the short round tube insert and connect, then rotate the outer shell to rotate the rotating assembly, and then drive the limit block and the slide groove to press tightly through the sliding assembly, so that the lower shell and the short round tube can be quickly installed; 2. When positioning and installing the short round tube and the long round tube with the reinforcement, put the upper shell and the short round tube into the long tube, and rotate the outer shell. At this time, the roller on the plug rod compresses the spring rod and moves along the inner slideway under the drive of the threaded rod and the threaded block until the shaft and the roller pass through the second plug hole and the slot limiter, so that the reinforcement and the long round tube can be positioned and tightened, and the reinforcement and the short round tube are tightened at the same time.
