A cable box is connected to the top of the top plate. Toothed plates are slidably arranged on the two sides of the top plate. Telescopic cylinders are symmetrically hinged to the two sides of the stand column. A gear is rotatably arranged in the middle of the two groups of toothed plates in the top plate. A transmission mechanism is connected to one end of the gear and penetrates through the top plate. A cable roller is connected to the other end of the transmission mechanism and penetrates into the cable box. A cable is wound on the outer wall of the cable roller. The telescopic cylinders are expanded to the two sides, so that the toothed plates on the two sides drive the connecting plates to slide to the outside, thereby forming an inverted trapezoid between the telescopic cylinders and the toothed plates. The cable roller is driven to rotate under the action of the transmission mechanism, so that the cable is kept in a tight state during the sliding process. When photovoltaic modules are installed subsequently, the overall deformation resistance is effectively increased.

Description

Technical Field

[0001] This invention relates to the field of flexible supports, specifically a large-span flexible support. Background Technology

[0002] Existing photovoltaic support structures are all rigid support structures. Most of the components of existing rigid support structures can be divided into front columns, rear columns, horizontal (diagonal) beams, purlins, diagonal supports, and back bracing, etc. These components are connected to each other by connectors, bolts, etc., to form a rigid support structure. In addition, photovoltaic support is a kind of support for placing, installing and fixing photovoltaic modules in a photovoltaic power generation system. With the rapid development of photovoltaic power station construction, photovoltaic support in complex terrains such as mountains and pools usually uses traditional flexible photovoltaic support.

[0003] Existing flexible support structures typically consist of cables connected to a base plate. When facing complex terrains such as mountains or pools, the span between the cables and the base plate becomes larger. After the photovoltaic panels are installed, the cables themselves deform under the influence of gravity, reducing the overall resistance to deformation and resulting in poor overall load-bearing capacity. This makes the structure highly susceptible to damage from wind loads outdoors, increasing overall maintenance costs and reducing the lifespan of the photovoltaic modules.

[0004] In summary, the cables of the aforementioned structure will deform under the influence of gravity during use, which can easily damage the device under wind load outdoors, increasing overall maintenance costs and reducing the lifespan of the photovoltaic modules. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a large-span flexible support to solve the technical problem that the device is easily damaged by wind loads outdoors, which increases the overall maintenance cost and reduces the service life of photovoltaic modules.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a large-span flexible support, comprising a column, a top plate installed on the top of the column, a cable box connected to the top of the top plate, and toothed plates slidably arranged on both sides of the top plate; telescopic cylinders symmetrically hinged to both sides of the column, and the other end of the telescopic cylinders hinged to the toothed plates; a gear rotatably arranged in the top plate between the two sets of toothed plates; one end of the gear penetrates the top plate and is connected to a transmission mechanism; the other end of the transmission mechanism penetrates into the cable box and is connected to a cable roller, and a cable is wound up on the outer wall of the cable roller.

[0007] By adopting the above technical solution, the telescopic cylinder unfolds to both sides, causing the toothed plates on both sides to slide the connecting plate outwards. This forms an inverted trapezoid between the telescopic cylinder and the toothed plates, further improving the overall stability of the device. When the toothed plates drive the connecting plate to unfold, the cable roller is rotated by the transmission mechanism. During this process, as the connecting plate slides to both sides, the cable rotates out of the cable box, ensuring that the cable remains taut throughout the sliding process. This effectively increases the overall resistance to deformation during the subsequent installation of photovoltaic modules.

[0008] The invention is further configured such that a connecting plate is installed on one side of each toothed plate, and the other end of the cable passes through the cable box and is connected to the inner side of the connecting plate.

[0009] By adopting the above technical solution, as the toothed plate slides to both sides, the connecting plate will slide accordingly, thereby pulling the cable out of the cable box and further ensuring a tighter connection between the cable and the connecting plate.

[0010] The present invention is further configured such that the transmission mechanism includes a driving disc, a transmission belt and a driven disc, the driving disc and the driven disc are connected by the transmission belt, one end of the gear is connected to the driving disc, and one end of the driven disc is connected to the cable roller.

[0011] By adopting the above technical solution, the gears between the gear plates will rotate during the sliding of the gear plates to both sides, thereby realizing that the driving plate will rotate and the driven plate will rotate under the action of the transmission belt. Thus, the rotation of the gears will cause the cable roller in the cable box to rotate and release the cable.

[0012] The invention is further configured such that a groove is provided at the bottom of the top plate at the telescopic cylinder, a slider is slidably disposed in the groove, and the bottom end of the slider is hinged to the other end of the telescopic cylinder.

[0013] By adopting the above technical solution, during the process of the toothed plate sliding to both sides, the slider will move in the groove. The cooperation between the slider and the groove helps to ensure the stability of the toothed plate sliding, and at the same time, it further enables the telescopic cylinder to rotate.

[0014] The present invention is further configured such that the telescopic cylinder includes a cylinder body and a telescopic rod, one end of the column is rotatably provided with the cylinder body, and the telescopic rod is slidably telescopically provided inside the cylinder body.

[0015] By adopting the above technical solution, the telescopic rod can be pulled out while the cylinder rotates, which facilitates the telescopic cylinder and the toothed plate to cooperate to form an inverted trapezoid.

[0016] The present invention is further configured such that a damping mechanism is provided between the toothed plate and the top plate, and is located on both sides of the top plate and is sealed between the toothed plate and the top plate.

[0017] By adopting the above technical solution, the stability of the subsequent gear plate in the top plate is ensured, preventing the gear plate from easily shifting position in the top plate. In addition, the sealing on both sides effectively prevents external impurities from entering the interior of the top plate, which would affect the normal rotation of the gear.

[0018] The present invention is further configured such that a mounting base is provided at the bottom of the column, and an array of threaded holes for bolt assemblies to be inserted are provided on the mounting base.

[0019] By adopting the above technical solution, the device can be easily moved to a designated position by the mounting base, and then fixed by the cooperation of the bolt assembly and the threaded hole on the base.

[0020] The present invention is further configured such that the slider is provided with a locking block that engages with the top of the slide groove, and the connection between the slide groove and the slider is provided with a rough surface.

[0021] By adopting the above technical solution, the action of the locking block ensures that the slider will not wobble during the sliding process in the groove. At the same time, the rough texture increases the sliding friction between the slider and the groove, further improving the stability of the toothed plate sliding in the top plate.

[0022] The invention is further configured such that a cleaning hole for the cable to pass through is provided through the cable box, and the cleaning hole is located in an open shape on the outside of the cleaning hole.

[0023] By adopting the above technical solution, the cleaning holes facilitate the removal of impurity particles adhering to the outer wall of the cable during the subsequent winding process. The open design prevents the accumulation of cleaned impurity particles at the cleaning holes.

[0024] In summary, the present invention has the following main beneficial effects:

[0025] 1. The present invention has a telescopic cylinder rotatably installed on one side of the column, and the other end of the telescopic cylinder is connected to the toothed plate. When facing a large-span mountain or pool, the telescopic cylinder will expand to both sides, causing the toothed plates on both sides to drive the connecting plate to slide outward. Thus, an inverted trapezoid is formed between the telescopic cylinder and the toothed plate, which further improves the overall stability of the device and ensures that it will not sway or tilt under the action of wind load.

[0026] 2. This invention features a cable roller rotatably mounted inside the cable box. When the toothed plate drives the connecting plate to unfold, the internal fixed gear rotates accordingly. Under the action of the transmission mechanism, the cable roller rotates. During this process, as the connecting plate slides to both sides, the cable rotates out of the cable box, ensuring that the cable remains taut throughout the sliding process. This effectively increases the overall resistance to deformation during subsequent installation of photovoltaic modules and further improves the overall service life. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of the present invention will now be described.

[0037] Example 1

[0038] A type of large-span flexible scaffold, such as Figures 1-7As shown, the device includes a column 1, a top plate 2, a cable box 5, a sliding mechanism, a support mechanism, and a winding mechanism. A mounting base is provided at the bottom of the column 1, with a series of threaded holes for bolt assemblies to engage. The mounting base facilitates the movement of the device to a designated position, where it is then fixed in place by the engagement of bolt assemblies with the threaded holes on the base. A top plate 2 is installed on the top of the column 1, with the cable box 5 connected to its top. Toothed plates 8 are slidably mounted on both sides of the top plate 2. Initially, when facing large-span mountains or pools, the toothed plates 8 can be slid to the sides as needed. Telescopic cylinders 3 are symmetrically hinged to both sides of the column 1, with the other end of the telescopic cylinder 3 connected to the toothed plate. The plates 8 are hinged together. As the toothed plates 8 slide to both sides, the telescopic cylinder 3 is stretched and rotated. At this time, the telescopic cylinder 3 and the toothed plates 8 form an inverted trapezoid, which further improves the overall stability of the device and ensures that it will not sway or tilt under wind load. At the same time, a gear 11 is rotatably installed in the top plate 2 between the two sets of toothed plates 8. One end of the gear 11 passes through the top plate 2 and is connected to the transmission mechanism 4. The other end of the transmission mechanism 4 passes through the cable box 5 and is connected to the cable roller. The cable 6 is wound on the outer wall of the cable roller. The cable roller is driven to rotate by the transmission mechanism 4. A connecting plate is installed on one side of each toothed plate, and the other end of the cable 6 passes through the cable box 5 and is connected to the inner side of the connecting plate 7. During this process, as the connecting plate 7 slides to both sides, the cable 6 rotates out of the cable box 5, ensuring that the cable 6 remains taut during the sliding process. This effectively increases the overall resistance to deformation when installing photovoltaic modules and further improves the overall service life.

[0039] Please see Figure 2 A groove 10 is provided at the bottom of the top plate 2, located at the telescopic cylinder 3. A slider 9 is slidably disposed in the groove 10, and the bottom end of the slider 9 is hinged to the other end of the telescopic cylinder 3. As the toothed plate 8 slides to both sides, it will drive the slider 9 to move within the groove 10. The cooperation between the slider 9 and the groove 10 helps to ensure the stability of the sliding of the toothed plate 8, and at the same time, it further allows the telescopic cylinder 3 to rotate. A locking block is provided on the slider 9 to engage with the top of the groove 10, and a rough surface is provided at the connection between the groove 10 and the slider 9. The locking block ensures that the slider 9 will not wobble during the sliding process within the groove 10. At the same time, the rough surface increases the sliding friction between the slider 9 and the groove 10, further improving the stability of the toothed plate 8 sliding within the top plate 2.

[0040] Please see Figure 1 and Figure 2A cleaning hole is provided through the cable box 5 for the cable 6 to pass through, and the cleaning hole is open on the outside. The cleaning hole facilitates the removal of impurities adhering to the outer wall of the cable 6 during the subsequent winding process. The open shape prevents the cleaning impurities from accumulating at the cleaning hole.

[0041] Example 2

[0042] like Figure 2 The large-span flexible support shown has an overall structure similar to that of Embodiment 1. The transmission mechanism 4 includes an active disc, a transmission belt, and a driven disc. The active disc and the driven disc are connected by the transmission belt. The active disc is connected to one end of the gear 11, and the driven disc is connected to the cable roller at one end. When the toothed plate 8 slides to both sides, it drives the gear 11 between the toothed plates 8 to rotate, thereby realizing that the active disc rotates accordingly. Under the action of the transmission belt, the driven disc rotates, thus realizing that when the gear rotates, the cable roller in the cable box 5 rotates to release the cable, thereby ensuring that the cable 6 remains taut during the sliding process.

[0043] The working principle of this invention is as follows: In use, the device is installed on a large-span mountain or pool. Then, by sliding the toothed plate 8 to both sides, the toothed plate 8 will drive the connecting plate 7 to move accordingly. With the cooperation of the gear 11 and the transmission mechanism 4, the cable roller in the cable box 5 is rotated and the cable is released. Since the column 1 and the toothed plate 8 are hinged by the telescopic cylinder 3, the telescopic cylinder 3 and the toothed plate 8 form an inverted trapezoid in the unfolded state, thereby improving the inherent stability of the column 1 and ensuring that the top plate 2 will not sway or tilt under the action of subsequent wind load. In addition, the connecting plate 7 will slide the cable 6 to both sides. With the action of the transmission mechanism 4, the cable 6 is kept in a taut state during the adjustment process. When installing photovoltaic modules, this effectively increases the overall resistance to deformation and further improves the overall service life.

[0044] Although embodiments of the present invention have been shown and described, these specific embodiments are merely illustrative of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
