Description

Technical Field

[0001] The invention relates to the field of flexible brackets, in particular to a large-span flexible bracket. Background Art

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

[0003] Existing flexible brackets are usually connected by cables and a base plate. When facing complex terrains such as mountains and pools, the span between the cables and the base plate will become larger. After the photovoltaic panels are installed on this flexible bracket, the cables themselves will deform under the action of gravity, thereby reducing the overall anti-deformation ability and resulting in poor overall load-bearing capacity of the cables. The device is easily damaged by wind loads outdoors, increasing the overall maintenance cost and reducing the service life of the photovoltaic modules.

[0004] In summary, during use, the cable of the above structure will deform due to the action of gravity, which can easily cause the device to be damaged under the action of wind load outdoors, increase the overall maintenance cost, and reduce the service life of the photovoltaic module. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a large-span flexible bracket to solve the technical problem that the device is easily damaged under the action of wind load outdoors, increasing the overall maintenance cost and reducing the service life of photovoltaic components.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a large-span flexible bracket, 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 tooth plates slidingly arranged on both sides of the top plate, telescopic cylinders symmetrically hinged on both sides of the column, and the other end of the telescopic cylinder is hinged to the tooth plate, a gear is rotatably arranged in the middle of the two groups of tooth plates in the top plate, one end of the gear passes through the top plate and is connected to a transmission mechanism, the other end of the transmission mechanism passes through the cable box and is connected to a cable roller, and a cable is wound on the outer wall of the cable roller.

[0007] By adopting the above technical solution, the telescopic cylinder will expand to both sides, so that the tooth plates on both sides drive the connecting plate to slide outward, thereby forming an inverted trapezoid between the telescopic cylinder and the tooth plate, further improving the overall stability of the device. When the tooth plate drives the connecting plate to expand, the cable roller is driven to rotate under the action of the transmission mechanism. In this process, the connecting plate slides to both sides, and the cable is rotated out of the cable box to ensure that the cable is always kept taut during the sliding process. When the photovoltaic components are installed later, the overall anti-deformation ability is effectively increased.

[0008] The present invention is further configured such that a connecting plate is installed on one side of the tooth 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, when the tooth plate slides to both sides, the connecting plate will slide along with it, and in this process the cable is pulled out of the cable box, thereby further ensuring that the cable and the connecting plate are more tightly connected.

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

[0011] By adopting the above technical solution, the gears between the tooth plates are driven to rotate during the process of the tooth plates sliding to both sides, thereby realizing the active plate to follow the rotation, and the driven plate is rotated under the action of the transmission belt, so that the cable roller in the cable box is rotated to release the cable during the rotation of the gear.

[0012] The present invention is further configured such that a slide groove is provided at the bottom of the top plate at the telescopic cylinder, a slider is slidably arranged in the slide 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, when the tooth plate slides to both sides, it will drive the slider to move in the slide groove. The cooperation between the slider and the slide groove can ensure the sliding stability of the tooth plate, and further enable the telescopic cylinder to rotate accordingly.

[0014] The present invention is further configured such that the telescopic cylinder comprises 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 and telescopically provided in the cylinder body.

[0015] By adopting the above technical solution, when the telescopic rod is pulled out, the cylinder body can be driven to rotate, thereby facilitating the cooperation between the telescopic cylinder and the toothed plate to form an inverted trapezoid.

[0016] The present invention is further configured such that a damping mechanism is provided between the tooth plate and the top plate, and a sealing arrangement is formed between the two sides of the top plate and the tooth plate.

[0017] By adopting the above technical solution, the stability of the subsequent tooth plate in the top plate is ensured, and the tooth plate is prevented from easily shifting in position in the top plate. The sealing settings on both sides effectively prevent foreign particles from entering the interior of the top plate, thereby affecting the normal rotation of the gear.

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

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

[0020] The present invention is further configured such that a block that is inserted into the top of the slide groove is provided on the slide block, and a rough surface is provided at the connection between the slide groove and the slide block.

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

[0022] The present 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 provided in an open shape outside the cleaning hole.

[0023] By adopting the above technical solution, the cleaning hole makes it easy to remove foreign particles adhered to the outer wall of the cable during the subsequent winding of the cable, and the open setting prevents the cleaned foreign particles from accumulating at the cleaning hole.

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

[0025] 1. The present invention has a telescopic cylinder rotatably arranged on one side of the column, and the other end of the telescopic cylinder is connected to the tooth plate. When facing a mountain or a pool with a large span, the telescopic cylinder will be unfolded to both sides, so that the tooth plates on both sides drive the connecting plate to slide outward, thereby forming an inverted trapezoid between the telescopic cylinder and the tooth plate, further improving the overall stability of the device and ensuring that it will not shake or tilt under the action of wind load;

[0026] 2. The present invention provides a cable roller for rotation in the cable box. When the tooth plate drives the connecting plate to unfold, the internal fixed gear will rotate accordingly, and the cable roller will be driven to rotate under the action of the transmission mechanism. In this process, when the connecting plate slides to both sides, the cable is rotated out of the cable box to ensure that the cable is always kept taut during the sliding process. When the photovoltaic components are installed later, the overall anti-deformation ability is effectively increased, and the overall service life is further improved.

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The following describes an embodiment of the present invention based on its overall structure.

[0037] Embodiment 1

[0038] A long-span flexible support, such as Figure 1-Figure 7As shown, it includes a column 1, a top plate 2, a cable box 5, a sliding mechanism, a supporting mechanism and a winding mechanism. A mounting seat is provided at the bottom of the column 1, and an array of threaded holes for bolt assemblies to be inserted into the mounting seat is provided. Under the action of the mounting seat, the device is conveniently moved to a specified position, and then it is limited and fixed by the cooperation of the bolt assembly and the threaded holes on the base. At the same time, a top plate 2 is installed on the top of the column 1, wherein the top of the top plate 2 is connected to the cable box 5, and tooth plates 8 are slidably provided on both sides of the top plate 2. In the initial state, when facing a mountain or a pool with a larger span, the tooth plates 8 are slid to both sides according to actual needs, and telescopic cylinders 3 are symmetrically hinged on both sides of the column 1, and the other end of the telescopic cylinder 3 is connected to the tooth plate 8. The plates 8 are hinged, and when the toothed plate 8 slides to both sides, the telescopic cylinder 3 is driven to stretch and rotate. At this time, the telescopic cylinder 3 and the toothed plate 8 are in an inverted trapezoid, which further improves the overall stability of the device and ensures that there will be no shaking and tilting under the action of wind load. At the same time, a gear 11 is arranged in the middle of the two sets of toothed plates 8 in the top plate 2, and one end of the gear 11 passes through the top plate 2 and is connected to the transmission mechanism 4, and the other end of the transmission mechanism 4 passes through the cable box 5 and is connected to the cable roller, and the cable 6 is wound on the outer wall of the cable roller, and the cable roller is driven to rotate under the action of the transmission mechanism 4. A connecting plate is installed on one side of the 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. In this process, when the connecting plate 7 slides to both sides, the cable 6 is rotated out of the cable box 5, ensuring that the cable 6 always remains in a taut state during the sliding process. When the photovoltaic module is installed later, the overall anti-deformation ability is effectively increased, and the overall service life is further improved.

[0039] See also Figure 2 The bottom of the top plate 2 is provided with a slide groove 10 at the telescopic cylinder 3, and a slider 9 is slidably arranged in the slide groove 10, and the bottom end of the slider 9 is hinged to the other end of the telescopic cylinder 3. When the tooth plate 8 slides to both sides, the slider 9 will be driven to move in the slide groove 10. The cooperation between the slider 9 and the slide groove 10 is convenient to ensure the sliding stability of the tooth plate 8, and further enables the telescopic cylinder 3 to rotate with it. At the same time, a block that is inserted into the top of the slide groove 10 is provided on the slider 9, and a rough surface is provided at the connection between the slide groove 10 and the slider 9. The block is used to ensure that the slider 9 will not shake during the sliding process in the slide groove 10. At the same time, the rough setting increases the sliding friction between the slider 9 and the slide groove 10, further improving the sliding stability of the tooth plate 8 in the top plate 2.

[0040] See also Figure 1 and Figure 2A cleaning hole for the cable 6 to pass through is provided on the cable box 5, and an opening is provided on the outside of the cleaning hole. The cleaning hole facilitates the removal of foreign particles adhered to the outer wall of the cable 6 during the subsequent winding of the cable 6, and the opening prevents the cleaned foreign particles from accumulating at the cleaning hole.

[0041] Embodiment 2

[0042] like Figure 2 A large-span flexible bracket is shown, and its overall structure is similar to that of Example 1, wherein the transmission mechanism 4 includes a driving disk, a transmission belt and a driven disk, the driving disk and the driven disk are connected by a transmission belt, one end of the gear 11 is connected to the driving disk, and one end of the driven disk is connected to the cable roller, and when the tooth plate 8 slides to both sides, the gear 11 between the tooth plates 8 is driven to rotate, thereby realizing that the driving disk follows the rotation, and the driven disk is rotated under the action of the transmission belt, so that when the gear rotates, the cable roller in the cable box 5 is rotated to release the cable, thereby ensuring that the cable 6 is always kept taut during the sliding process.

[0043] The working principle of the present invention is as follows: when in use, the device is installed on a mountain or a pool with a larger span, and then the tooth plate 8 is slid to both sides. At this time, the tooth plate 8 will drive the connecting plate 7 to follow the movement, and with the cooperation of the gear 11 and the transmission mechanism 4, the cable roller in the cable box 5 is driven to rotate and the cable is released. Since the column 1 and the tooth plate 8 are hinged by the telescopic cylinder 3, an inverted trapezoid is formed between the telescopic cylinder 3 and the tooth plate 8 in the unfolded state, thereby improving the self-stability of the column 1 and ensuring that the top plate 2 will not shake or tilt under the subsequent wind load. The connecting plate 7 will slide the cable 6 to both sides. Under the action of the transmission mechanism 4, the cable 6 itself is in a taut state during the adjustment process. When the photovoltaic components are installed later, the overall anti-deformation ability is effectively increased, and the overall service life is further improved.

[0044] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
