Description

Technical Field

[0001] This invention relates to the field of flexible photovoltaic support technology, specifically to a reinforcing structure for a flexible support circular tube. Background Technology

[0002] Flexible photovoltaic (PV) support systems feature large spans, high clearance, long spacing, low cost, and environmental friendliness, effectively addressing the adaptability issues of support systems in complex terrain scenarios. A flexible PV support system is a large-span, multi-span structure. This structure combines prestressed steel wire ropes tensioned between two fixed points with a flexible support system for lateral connections. The fixed points utilize rigid structures and external inclined steel strands to provide support and reaction force.

[0003] Currently, flexible support systems primarily use various shapes, such as round tubes, for lateral connection. However, the main drawback of round tube lateral connection systems is that the round tube is a single tube, and the strength at its flattened ends is insufficient. Therefore, it is prone to deformation or breakage at the flattened ends under strong tension. Summary of the Invention

[0004] This invention proposes a reinforced structure for a flexible support tube, which solves the problem in the prior art that the flattened part is not strong enough and is prone to deformation or breakage under strong tension.

[0005] The technical solution of the present invention is as follows: A reinforcing structure for a flexible support tube includes a long tube, short tubes are fitted inside both ends of the long tube, and a locator for fixing the short tubes and the long tube. The locator includes a housing, an active chamber is provided inside the housing, a telescopic slot communicating with the active chamber is provided circumferentially on the housing, a cross groove corresponding to the telescopic slot is provided on the inner wall of the long tube, a positioning hole is provided radially on the long tube at the end of the cross groove, a guide post is fixed inside the active chamber and aligned with the axial direction of the housing, and a locking component and a spring that elastically drives the locking component to lock at the positioning hole are provided on the guide post.

[0006] Preferably, the positioner includes a housing, the housing having an active chamber, the housing having a telescopic slot communicating with the active chamber in the circumferential direction, the inner wall of the elongated tube having cross grooves corresponding to the telescopic slots, the elongated tube having a positioning hole at the end of the cross grooves in the radial direction, a guide post fixed in the active chamber and aligned with the axial direction of the housing, the guide post being provided with a locking component and a spring that elastically drives the locking component to engage with the positioning hole.

[0007] Preferably, the locking assembly includes a slip ring, which is slidably sleeved on the outside of the guide post. A first connecting ear with a cross-shaped distribution is fixed on the outer surface of the slip ring. A T-shaped stop is slidably arranged in the telescopic slot. A second connecting ear is fixed at the end of the T-shaped stop near the active chamber. The first connecting ear and the second connecting ear are hinged together by a connecting rod.

[0008] Preferably, the T-shaped stop is adapted to the width of the cross groove and the positioning hole, and the outer end of the T-shaped stop is provided with a bevel.

[0009] Preferably, the T-shaped blocks are arranged in a cross shape along the axis of the housing, and the T-shaped blocks are arranged alternately along the axial direction of the housing.

[0010] Preferably, the spring is sleeved outside the guide post, one end of the spring is fixed to the slip ring, and the other end of the spring is fixed to the movable chamber.

[0011] Preferably, the inner wall of one end of the short round tube is provided with an internal thread, and one end of the housing is provided with a threaded connection part that mates with the thread of the short round tube.

[0012] Preferably, the outer surface of the housing at the end away from the threaded connection is provided with anti-slip stripes.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. In this invention, two short round tubes are fitted onto both ends of a long round tube. To facilitate connection, the overlapping parts of the long and short round tubes are flattened by an extruder to facilitate drilling. This reinforcement method solves the problem of insufficient strength at the flattened part of the round tube in the prior art. This invention uses short round tubes only to reinforce both ends, which not only ensures structural strength but also reduces material usage and lowers material costs.

[0015] 2. In this invention, a locator is used. By inserting a short round tube equipped with the locator into the inner side of the end of a long round tube, and ensuring that a portion of the T-shaped stop is exposed in the shell, the T-shaped stop is inserted into the cross groove. During this process, the outer inclined surface of the T-shaped stop is compressed and retracts into the telescopic groove. Then, through the hinge relationship of the connecting rod, the slip ring is pushed and the spring is stretched. When the T-shaped stop slides along the cross groove to the end, under the elastic force of the spring, the T-shaped stop automatically pops out from the telescopic groove and is locked in the positioning hole. Thus, the locator fixes the short round tube to the inner side of the end of the long round tube, realizing the positioning and installation of the short round tube and the long round tube, and preventing slippage between the round tubes during the flattening process.

[0016] 3. In this invention, each T-shaped stop is distributed in a cross shape along the axis of the shell, so that the distribution of each T-shaped stop is uniform. Each T-shaped stop is arranged alternately along the axial direction of the shell, which can prevent the positioning holes from being at the same cross-sectional position, thus preventing the long round tube from breaking at the positioning hole and helping to maintain the structural stability of the long round tube.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides a technical solution: a reinforcing structure for a flexible support tube, comprising a long tube 1, short tubes 3 fitted inside both ends of the long tube 1, and a locator 4 for fixing the short tubes 3 to the long tube 1. (See also...) Figure 8 and Figure 9 The positioner 4 includes a housing 41, inside which is a movable chamber 413. A telescopic slot 414 communicating with the movable chamber 413 is circumferentially opened on the housing 41. Cross grooves 12, corresponding to the telescopic slots 414, are opened on the inner wall of the elongated tube 1. A positioning hole 11 is radially opened on the elongated tube 1 at the end of the cross grooves 12. A guide post 42, aligned axially with the housing 41, is fixed inside the movable chamber 413. A locking component 43 and a spring 44 elastically drive the locking component 43 to engage with the positioning hole 11 are provided on the guide post 42. The locking component 43 includes a slip ring 431, which is slidably sleeved on the outside of the guide post 42. A first connecting lug 432, arranged in a cross shape, is fixed on the outer surface of the slip ring 431. A T-shaped stop 434 is slidably arranged inside the telescopic slot 414. The T-shaped stop 434 is fixed with a second connecting ear 435 at one end near the active chamber 413. The first connecting ear 432 and the second connecting ear 435 are hinged together by a connecting rod 433. The T-shaped stop 434, which is partially exposed on the housing 41, is inserted into the cross groove 12. During this process, the outer inclined surface of the T-shaped stop 434 is compressed and retracts into the telescopic groove 414. Then, through the hinge relationship of the connecting rod 433, the slip ring 431 is pushed and the spring 44 is stretched. When the T-shaped stop 434 slides to the end along the cross groove 12, the spring force of the spring 44 drives the T-shaped stop 434 to automatically pop out from the telescopic groove 414 and lock into the positioning hole 11. Then, the positioning device 4 fixes the short round tube 3 to the inner side of the end of the long round tube 1, realizing the positioning and installation of the short round tube 3 and the long round tube 1.

[0032] It should be noted that the width of the T-shaped stop 434 is adapted to the width of the cross groove 12 and the positioning hole 11. The groove shape of the cross groove 12 guides the sliding direction of the T-shaped stop 434 to help the T-shaped stop 434 accurately fit into the positioning hole 11. The outer end of the T-shaped stop 434 is provided with a bevel. When the T-shaped stop 434, which is partially exposed on the housing 41, is inserted into the cross groove 12, the bevel at the outer end of the T-shaped stop 434 is compressed and retracts into the telescopic slot 414.

[0033] To elaborate further, please refer to Figure 10 and Figure 11 Each T-shaped stop 434 is arranged in a cross shape along the axis of the housing 41, so that the distribution of each T-shaped stop 434 is uniform. Each T-shaped stop 434 is arranged alternately along the axial direction of the housing 41, so that each positioning hole 11 is not at the same cross-sectional position, thereby preventing the long round tube 1 from breaking at the positioning hole 11 and helping to maintain the structural stability of the long round tube 1.

[0034] Spring 44 is sleeved on the outside of guide post 42. One end of spring 44 is fixed to slip ring 431, and the other end of spring 44 is fixed to movable chamber 413. When no external force is applied, spring 44 pushes slip ring 431. Through the hinge relationship of connecting rod 433, each T-shaped stop 434 can tend to extend outward.

[0035] The inner wall of one end of the short round tube 3 is provided with an internal thread, and one end of the housing 41 is provided with a threaded connection part 411 that is threaded with the short round tube 3, so as to facilitate the assembly and fixation of the short round tube 3 and the positioner 4.

[0036] It should be added that the outer surface of the end of the housing 41 away from the threaded connection part 411 is provided with anti-slip stripe part 412, so as to facilitate the turning of the positioner 4 and the positioning device 4 and the short round tube 3 are installed and fixed.

[0037] Based on the above embodiments, an implementation of a flexible support tube reinforcement structure according to the present invention includes the following steps:

[0038] Step 1: Assemble the short round tube 3 and the positioner 4. Thread the positioner 4 onto one end of the short round tube 3. At this time, the positioner 4 should... Figure 7 As shown, it is installed at one end of the short round tube 3;

[0039] Step two, assembling the short round tube 3 and the long round tube 1: Insert the end of the short round tube 3 equipped with the locator 4 into the inner side of the end of the long round tube 1, and use the locator 4 to fit the short round tube 3 and the long round tube 1 together and position them as one unit. At this time, the short round tube 3 is as follows... Figure 3 As shown, it is installed at one end of the long cylindrical tube 1 via the locator 4;

[0040] Step 3: Flattening the positioning body. The overlapping portion of the short round tube 3 and the long round tube 1 is extruded into a flat end 2 under the processing of an extruder. At this time, the short round tube 3 is as follows: Figure 4 The figure shows the extrusion forming a flat end 2;

[0041] Step four: Drilling holes in the connector. Following the steps above, use the locator 4 to fit and position the short round tube 3 onto the long round tube 1 at the other end of the long round tube 1, then flatten it into shape. Then, use a drilling machine to drill round holes 21 at both flat ends 2 of the long round tube 1.

[0042] Based on the above embodiments, the working principle and usage process of the present invention are as follows: Step 1, assembly of the short round tube 3 and the locator 4; Step 2, assembly of the short round tube 3 and the long round tube 1; Step 3, flattening of the locator; Step 4, drilling of the connector, wherein the specific process of assembling the short round tube 3 and the long round tube 1 is as follows: insert the short round tube 3 with the locator 4 into the inner side of the end of the long round tube 1, and ensure that a portion of the T-shaped stop 434 exposed in the housing 41 is inserted into the cross groove 12. During this process, the T-shaped stop... The outer end of block 434 is compressed and retracts into the telescopic groove 414. Then, through the hinge of connecting rod 433, it pushes slip ring 431 and stretches spring 44. When T-shaped stop block 434 slides to the end along cross groove 12, under the elastic force of spring 44, T-shaped stop block 434 is automatically ejected from telescopic groove 414 and locked in positioning hole 11. Then, through positioning device 4, short round tube 3 is fixedly fitted into the inner side of the end of long round tube 1, realizing the positioning and installation of short round tube 3 and long round tube 1.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
