Description

Technical Field

[0001] This application relates to the technical field of flexible photovoltaic brackets, and particularly to a strengthening structure for a circular tube of a flexible bracket. Background Art

[0002] At present, flexible photovoltaic brackets have the characteristics of "large span, high clearance, long row spacing, low cost, and environmental friendliness", and can effectively solve the adaptability problem of brackets in some complex terrain scenarios. A flexible photovoltaic bracket is a large-span multi-span structure, which combines prestressed steel wires tensioned between two fixed points at both ends with a flexible bracket transverse connection system. The fixed points use a rigid structure and outer stay cables to provide support reaction force.

[0003] Among them, the flexible bracket transverse connection system is currently mainly composed of various shapes such as circular tubes. The main disadvantage of the circular tube transverse connection system is that the circular tube is a single tube, and the strength at the flattened parts at both ends is insufficient. Therefore, it is easy to deform or break at the flattened parts under strong tension. Summary of the Invention

[0004] In order to solve the problem in the prior art that the strength of the flattened part of the circular tube of the flexible bracket is insufficient, and it is easy to deform or break at the flattened part under strong tension, this application provides a strengthening structure for a circular tube of a flexible bracket.

[0005] The strengthening structure for a circular tube of a flexible bracket provided by this application adopts the following technical solutions:

[0006] A strengthening structure for a circular tube of a flexible bracket includes a long circular tube, a short circular tube is sleeved inside the long circular tube, and further includes a strengthening member. The strengthening member includes a connecting part and an installation part. When the strengthening member is vertically arranged, the connecting part includes a lower shell and a limiting block. The limiting block is slidably connected to the lower shell, and the sliding direction of the limiting block slides along the direction close to or away from the center position of the lower shell. A limiting groove is opened on the short circular tube, and the limiting block penetrates through the side wall of the lower shell and slides along the length direction of the limiting groove. A sliding component for driving the limiting block to abut against the limiting groove is arranged inside the lower shell; the installation part includes an upper shell and a plug rod. The upper shell is fixed to the lower shell, a slot is opened on the long circular tube, and a driving component for driving the plug rod and the slot to be inserted and connected is arranged inside the upper shell.

[0007] By adopting the above technical solution, when connecting the long circular tube and the short circular tube, first install the short circular tube and the lower shell. Initially, the limit block penetrates through the lower shell. The limit block first inserts and slides along the limit groove on the short circular tube, and then the sliding assembly drives the limit block to slide, so that the limit block abuts against the limit groove, which can complete the rapid installation of the lower shell and the short circular tube. Then, the short circular tube installed with the reinforcement is sleeved inside the long circular tube. When the reinforcement is installed with the long circular tube, the driving assembly can drive the insertion rod and the slot to be quickly connected, so as to realize the positioning installation of the short circular tube and the long circular tube, reduce the sliding between the circular tubes during the later flattening process, and also increase the strength of the flattened part of the circular tube.

[0008] Optionally, the sliding assembly includes a push rod, a sliding plate and a driving disk. The sliding plate and the driving disk are coaxially arranged. The sliding plate is fixed to the lower shell. The push rod slides radially along the sliding plate relative to the sliding plate. The driving disk rotates relative to the lower shell. The rotation axis direction of the driving disk is along the vertical direction. A rotating assembly for driving the driving disk to rotate is arranged inside the lower shell. An arc-shaped sliding hole is formed 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.

[0009] 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. Under the limiting action of the sliding plate, the push rod is driven by the driving disk to slide reciprocally along the radial direction of the sliding plate, so as to realize the abutment of the limit block against the sliding groove.

[0010] Optionally, a linear sliding rail is formed on the sliding plate. The sliding rail is arranged along the radial direction of the sliding plate. The push rod slides along the length direction of the sliding rail inside the sliding rail.

[0011] By adopting the above technical solution, the push rod moves along the length direction of the sliding rail, which can make the push rod move more stably.

[0012] Optionally, the rotating assembly includes a gear ring, a driving gear, a connecting rod and a transmission gear. An outer shell is rotatably arranged on the circumference of the lower shell. The outer shell is fixed to the gear ring. One end of the connecting rod is fixed to the driving gear, and the other end is fixed to the transmission gear. The driving gear meshes with the gear ring, and the transmission gear meshes with the driving plate.

[0013] By adopting the above technical solution, rotate the outer shell. The outer shell drives the gear ring to rotate. The gear ring meshes with the driving gear, so as to drive the driving gear to rotate. The driving gear is connected to the transmission gear through the connecting rod, that is, the transmission gear rotates, and the rotation of the transmission gear can drive the driving plate to rotate.

[0014] Optionally, two driving gears, connecting rods and transmission gears are respectively arranged, and are all symmetrically arranged along the central position of the driving disk.

[0015] By adopting the above technical solution, the driving gears, connecting rods and transmission gears are symmetrically arranged along the driving disk respectively, which is convenient for keeping stable when driving the driving disk to rotate.

[0016] Optionally, the driving assembly includes a rotating tooth, a threaded rod, and a threaded block. The rotating tooth meshes with the driving tooth, the rotating tooth is fixed to the threaded rod, the threaded block is threadedly connected to the threaded rod, and the insertion rod is fixed to the threaded block.

[0017] By adopting the above technical solution, when the driving tooth rotates, it drives the rotating tooth to rotate. The rotation of the rotating tooth drives the threaded rod to rotate. While the threaded rod rotates, it is threadedly connected to the threaded block. Since the threaded block is fixed to the insertion rod and the insertion rod passes through the upper housing and is limited by the slot, when the upper housing and the long circular tube are installed, the threaded block can be driven to move along the length direction of the threaded rod.

[0018] Optionally, an inner slideway is vertically formed on the inner wall of the upper housing. First insertion holes and second insertion holes are spaced apart on the inner slideway. The first insertion holes and the second insertion holes are spaced apart in a direction away from the lower housing. The second insertion hole corresponds to the slot. The insertion rod reciprocally slides along the length direction of the inner slideway. Before the upper housing and the long circular tube are installed, the insertion rod passes through the first insertion hole.

[0019] By adopting the above technical solution, before the upper housing and the long circular 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, which can make the insertion rod remain stable and not move up and down when the reinforcing member and the lower housing are installed.

[0020] Optionally, a spring rod is fixed to one 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. When the upper housing and the long circular tube are installed, the roller abuts against and rolls on the inner wall of the long circular tube. The spring rod is in a compressed state until the roller passes through the second insertion hole and is limited by the slot.

[0021] By adopting the above technical solution, when the upper housing and the long circular tube are installed, the roller abuts against the inner wall of the long circular tube, compressing the spring rod. At this time, the outer housing is rotated, so that the driving tooth drives the rotating tooth to rotate. The roller and the insertion rod are driven by the threaded block to slide along the inner slideway of the upper housing until the insertion rod moves to the position of the second insertion hole. The spring rod returns to its original length, so that the roller is limited by the slot. When the outer housing is rotated, the rotating assembly rotates at the same time, and the sliding assembly drives the limiting block to abut tightly against the chute of the lower housing, simultaneously realizing the positioning and fixing of the reinforcing member, the long circular tube, and the short circular tube.

[0022] Optionally, the edge of one side of the first insertion hole facing the threaded rod is provided with an inclined section.

[0023] By adopting the above technical solution, the edge of one side of the first insertion hole facing the threaded rod is provided with an inclined section, which can make it more labor-saving for the roller and the rotating shaft to retract from the first insertion hole into the upper housing.

[0024] Optionally, grooves are symmetrically formed on the side wall of the slot. Both ends of the rotating shaft are inserted and connected to the grooves.

[0025] By adopting the above technical solution, when the roller and the rotating shaft are inserted and connected to the slot, the rotating shaft can be inserted into the groove, making the installation between the upper shell and the oval tube more stable.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When the reinforcing member is installed on the short circular tube, first insert the limiting block into the sliding groove on the inner wall of the short circular tube, then rotate the outer shell to make the rotating assembly rotate, and then drive the limiting block to be tightly pressed against the sliding groove through the sliding assembly, so as to realize the rapid installation of the lower shell and the short circular tube;

[0028] 2. When the short circular tube with the reinforcing member is positioned and installed on the oval tube, sleeved the upper shell and the short circular tube into the long tube, and rotate the outer shell. At this time, the roller on the insertion rod compresses the spring rod and moves along the inner slideway under the drive of the threaded rod and the threaded block until the rotating shaft and the roller penetrate through the second jack and are limited by the slot, so as to realize the positioning and fastening of the reinforcing member and the oval tube, and at the same time, the reinforcing member and the short circular tube are fastened.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 5 drawings.

[0036] An embodiment of the present application discloses a strengthening structure for a flexible support round tube.

[0037] Reference Figure 1 , a strengthening structure for a flexible support round tube includes a long round tube 1, a short round tube 2 and a strengthening member 3. The installation steps of the flexible support round tube are as follows: First, install the short round tube 2 and the strengthening member 3, then insert the short round tube 2 with the strengthening member 3 installed into the end of the long round tube 1 to complete the positioning installation of the strengthening member 3 and the long round tube 1, that is, complete the assembly of the short round tube 2 and the long round tube 1. Then, press the overlapping part of the long round tube 1 and the short round tube 2 into a flat end under the processing of an extruder, and punch a round hole with a punching machine to facilitate subsequent connection and installation.

[0038] Reference Figure 2 , Figure 3 and Figure 4 , taking the strengthening member 3 at one end of the long round tube 1 as an example, when the strengthening member 3 is vertically arranged, the strengthening member 3 includes a connecting portion 31 and an installation portion 32. The connecting portion 31 includes a lower housing 311, and a plurality of limiting blocks 312 are slidably arranged in the lower housing 311. The plurality of limiting blocks 312 are circumferentially spaced along the lower housing 311. A plurality of limiting grooves 21 are vertically opened on the short round tube 2. Before the lower housing 311 is installed with the short round tube 2, the limiting blocks 312 penetrate through the side wall of the lower housing 311. When the lower housing 311 is installed with the short round tube 2, the limiting blocks 312 are inserted and embedded with the limiting grooves 21 and slide along the limiting grooves 21.

[0039] Reference Figure 2 , Figure 3 and Figure 4 , a sliding assembly 4 is arranged in the lower housing 311. The sliding assembly 4 includes a push rod 41, a sliding plate 42 and a driving disk 43. The sliding plate 42 and the driving disk 43 are coaxially arranged. The sliding plate 42 is horizontally fixed to the lower housing 311. A plurality of linear slide rails 421 are opened on the sliding plate 42. The plurality of slide rails 421 are equidistantly distributed along the radial direction of the sliding plate 42. The push rod 41 slides in the slide rails 421. The driving disk 43 rotates relative to the lower housing 311. The rotation axis direction of the driving disk 43 is along the vertical direction. A plurality of arc-shaped sliding holes 431 are opened on the driving disk 43. One end of the push rod 41 slides along the sliding holes 431, and the other end is fixed to the limiting block 312.

[0040] Reference Figure 2 , Figure 3 and Figure 4, a rotating assembly 5 is arranged inside the lower housing 311. The rotating assembly 5 includes a toothed ring 51, a driving gear 52, a connecting rod 53, and a transmission gear 54. An outer housing 511 is rotatably arranged on the circumferential side of the lower housing 311. The outer housing 511 is fixedly connected to the toothed ring 51. There are two driving gears 52, connecting rods 53, and transmission gears 54 respectively, and they are all arranged axially symmetrically along the driving disk 43. The connecting rod 53 is arranged vertically, with one end fixedly connected to the driving gear 52 and the other end fixedly connected to the transmission gear 54. The driving gear 52 meshes with the toothed ring 51, and the transmission gear 54 meshes with the driving plate. When the outer housing 511 is rotated, the toothed ring 51 rotates, driving the driving gear 52 and the transmission gear 54 to rotate, thereby driving the driving disk 43 to rotate. When the driving disk 43 rotates, the sliding hole 431 rotates accordingly. Under the limiting action of the sliding rail 421, the push rod drives the limiting block 312 to be pressed against the limiting groove 21.

[0041] Reference Figure 4 and Figure 5 , the installation part 32 includes an upper housing 321. The upper housing 321 is fixedly connected to the lower housing 311. A plurality of insertion rods 322 are arranged inside the upper housing 321. The plurality of insertion rods 322 are spaced apart along the circumferential direction of the upper housing 321. A spring rod 3221 is fixed to the end of the insertion rod 322. A rotating shaft is fixed to the spring rod 3221, and a roller 3222 is rotatably connected to the rotating shaft. An inner sliding track 7 is vertically opened on the inner wall of the upper housing 321. A first insertion hole 71 and a second insertion hole 72 are opened on the inner sliding track 7. The first insertion hole 71 and the second insertion hole 72 are spaced apart in the direction away from the lower housing 311. A bevel surface is arranged on the side of the first insertion hole 71 facing the inside of the upper housing 321. An outer sliding track is vertically opened on the long circular tube 1, and a slot 11 is opened on the outer sliding track. The second insertion hole 72 corresponds to the outer sliding track.

[0042] Reference Figure 4 and Figure 5, a driving assembly 6 is arranged inside the upper housing 321. The driving assembly 6 includes a rotating gear 61, a threaded rod 62, and a threaded block 63. The rotating gear 61 meshes with the driving gear 52. The rotating gear 61 is fixed to the threaded rod 62. The threaded block 63 is threadedly connected to the threaded rod 62. The insertion rod 322 is fixed to the threaded block 63. Before the upper housing 321 and the long circular tube 1 are installed, the roller 3222 and the spring rod 3221 penetrate through the first jack 71. When the upper housing 321 and the long circular tube 1 are installed, the roller 3222 abuts against the outer slideway inside the long circular tube 1, compressing the spring rod 3221. Rotate the outer housing 511. When the toothed ring 51 rotates, it drives the rotating gear 61 to rotate. At this time, the threaded rod 62 rotates. The end of the insertion rod 322 is limited inside the inner slideway 7. Therefore, the threaded block 63 moves along the length direction of the threaded rod 62. At this time, the insertion rod 322 and the roller 3222 move along the inner slideway 7 until the insertion rod 322 moves to the position of the second jack 72. The spring rod 3221 returns to its original length. The roller 3222 penetrates through the second jack 72 and is limited by the slot 11. A groove is also formed on the side wall of the slot 11. The rotating shaft on the roller 3222 can be limited by the groove, increasing the installation stability of the insertion rod 322 and the long circular tube 1. When the outer housing 511 rotates, the rotating assembly 5 also rotates. At this time, the sliding assembly 4 can drive the limiting block 312 to abut tightly against the chute of the short circular tube 2, thereby realizing the tight connection between the short circular tube 2 and the long circular tube 1.

[0043] The implementation principle of the strengthening structure of the flexible support circular tube in the embodiment of the present application is as follows: In the installation connection of the short circular tube 2 and the long circular tube 1, first connect the strengthening member 3 and the short circular tube 2. At this time, first insert and embed the limiting block 312 into the chute, and then rotate the outer housing 511 to make the rotating assembly 5 rotate, driving the driving disk 43 to rotate, so that the limiting block 312 abuts tightly against the chute. Then, install the short circular tube 2 with the strengthening member 3 into the long circular tube 1. When the upper housing 321 and the long circular tube 1 are installed, the roller 3222 compresses the spring rod 3221 and retracts into the inner slideway 7 of the upper housing 321. Rotate the outer housing 511. When the threaded block 63 rotates along the threaded rod 62, it moves along the length direction of the threaded rod 62, so that the insertion rod 322 moves from the first jack 71 to the second jack 72 and is limited and fixed to the slot 11 on the long tube, thereby realizing the installation of the strengthening member 3 and the long circular tube 1, that is, the connection between the short circular tube 2 and the long circular tube 1. Subsequently, use an extruder to flatten the overlapping part of the long circular tube 1 and the short circular tube 2, and use a punching machine to punch a round hole to complete the installation preparation work of the flexible support circular tube.
