Description

A photovoltaic flexible bracket and steel cable support unit Technical Field

[0001] The present application relates to the technical field of photovoltaic flexible brackets, and further to a photovoltaic flexible bracket and a steel cable support unit. Background Art

[0002] As an important component of photovoltaic power generation systems, photovoltaic brackets have various structural forms to meet market demand. In recent years, photovoltaic flexible brackets have been widely used in production and daily life due to their simple and lightweight structure, low cost, strong pre-assembly, and flexible installation for large spans.

[0003] In the related art, the most commonly used photovoltaic flexible bracket is a three-cable flexible photovoltaic bracket. This refers to a structural system consisting of two upper load-bearing steel cables, a lower stabilizing steel cable, and multiple cable rods connected between the three cables, used to stably support the photovoltaic modules. Currently, the cables in the three-cable flexible photovoltaic brackets on the market are mostly made by flattening the ends of round tubes. However, this manufacturing process has a low cable yield rate and high production costs. In addition, manual intervention during the process destroys the structural form of the round tube, resulting in low cable durability and poor performance, leaving room for improvement.

[0004] Utility Model Content

[0005] The purpose of this application is to provide a photovoltaic flexible bracket and a steel cable support unit to improve the structural durability of the cable rod and ensure its performance. At the same time, it improves its production yield and reduces the production cost of the corresponding photovoltaic flexible bracket.

[0006] The technical solutions provided in this application are as follows:

[0007] In one aspect, the present application provides a photovoltaic flexible bracket cable support unit, comprising: a cable rod and a connecting seat;

[0008] The cable rod comprises a circular tubular body for supporting adjacent steel cables;

[0009] A fixing piece is fixed on each of the two ends of the circular tubular body, and an opening groove is provided on each of the fixing pieces;

[0010] The connecting seat at least partially extends into the opening slot and is fixedly connected to the fixing member via a locking member to connect the cable rod to the steel cable.

[0011] Through the photovoltaic flexible bracket steel cable support unit provided by the present application, the main part of the cable rod is set to be a circular tube, and fixing parts with open grooves are respectively provided at both ends of the circular tube-shaped main body; in actual application, after the connecting seat is set on the corresponding steel cable, the connecting seat is at least partially extended into the open groove, and the fixing seat and the corresponding end of the cable rod are connected through the open groove, so that the cable rod can be installed on the corresponding steel cable.

[0012] By adopting this method, on the one hand, since the main part of the cable rod is not subject to human intervention, the structural durability of the cable rod is higher. Compared with angle steel or C-shaped steel, although the circular tubular main body has a similar cross-sectional area to the former two, its section modulus is larger, its bending resistance is stronger, and its performance is better. At the same time, the overall structure of the cable rod is more beautiful, production is more convenient, and the production yield of the cable rod is higher, which effectively saves the company's production costs.

[0013] In some embodiments, the fixing member includes a first fixing plate, a bottom plate, and a second fixing plate, the first fixing plate and the second fixing plate being arranged in parallel and spaced apart, the bottom plate being arranged between the first fixing plate and the second fixing plate, and two ends of the bottom plate being fixed to the first fixing plate and the second fixing plate respectively, and the first fixing plate, the bottom plate, and the second fixing plate jointly enclose the open slot;

[0014] The two ends of the circular tubular body are respectively connected to a surface of the corresponding bottom plate that is away from the corresponding first fixing plate and the corresponding second fixing plate in the thickness direction;

[0015] The first fixing plate and the second fixing plate are detachably connected to the corresponding connecting seat through a locking piece, so that the corresponding end of the cable rod is fixedly connected to the corresponding steel cable.

[0016] The photovoltaic flexible bracket cable support unit provided by the present application utilizes a first fixing plate, a bottom plate and a second fixing plate to enclose an open groove; in actual operation, after the connecting seat is installed at the specified position in the length direction of the corresponding steel cable, the cable rod is placed between the two steel cables, and the open groove ends of the two fixing members are respectively buckled on the corresponding connecting seats on the two steel cables, and then the corresponding fixing members are fixedly connected to the corresponding connecting seats with locking members, thereby achieving the support and connection of the corresponding cable rod between the two steel cables; compared with the related art which adopts the process of flattening the two ends of the round tube to form the cable rod, the cable rod is formed in this way, and the two ends of the cable rod are sealed by the bottom plate of the fixing member, and only the main body needs to be fixed during the production process. The outer wall is treated with anti-rust treatment, and the anti-rust process is simple, easy to operate, and highly efficient, which reduces the process cost. Moreover, compared with the operation of connecting the L-shaped angle steel or C-shaped steel to the connecting seat at the side, the fixing piece is connected to the connecting seat through the first fixing plate and the second fixing plate. Due to the different force directions, the defect of eccentric force is overcome, and the probability of bending moment generation is effectively reduced, making the structure of the cable rod more durable and the performance better, effectively extending its service life, and improving the structural stability of the corresponding photovoltaic flexible bracket. In addition, the process of connecting the fixing piece to the main body has various process methods, simple operation, and convenient manufacturing, which makes the cable rod have a higher yield rate, which helps to further reduce the company's production costs.

[0017] In some embodiments, a reinforcing rib plate is provided between the first fixing plate and the second fixing plate.

[0018] Through the photovoltaic flexible bracket steel cable support unit provided by this application, the reinforcing ribs are used to improve the structural strength of the fixing parts, reduce the probability of local buckling of the fixing parts during use, and help to further extend the service life of the cable rod, thereby improving its performance.

[0019] In some embodiments, the locking member comprises a locking bolt;

[0020] The threaded end of the locking bolt vertically passes through the first fixing plate, the connecting seat and the second fixing plate in sequence, and is threadably engaged with the three.

[0021] The first fixing plate, the bottom plate and the second fixing plate are integrally bent and formed.

[0022] The photovoltaic flexible bracket steel cable support unit provided in this application utilizes a plate bending process to form a fixing part, which helps to improve the structural integrity and structural strength of the fixing part, thereby ensuring the performance of the corresponding cable rod.

[0023] At the same time, the fixing part and the connecting seat are connected by locking bolts to achieve a detachable connection between the fixing part and the connecting seat. The connection structure is simple and easy to install. While improving the assembly efficiency and assembly cost of the corresponding ends of the cable rods and the corresponding steel cables, it helps to improve the ease of use of the photovoltaic flexible bracket cable support unit.

[0024] In some embodiments, the connecting seat includes a pressing block and a backing plate;

[0025] A first through slot is formed on one side of the pressing block in a thickness direction thereof, and the backing plate is detachably connected to the side of the pressing block where the first through slot is formed;

[0026] The fixing member is connected to one end of the pressing block facing away from the backing plate.

[0027] The photovoltaic flexible bracket steel cable support unit provided by the present application utilizes a pad and a first through groove opened on the pressure block to form a through hole for the steel cable to pass through, and the overall structure of the connecting seat is simple; during specific operation, the staff will embed the corresponding segment of the steel cable into the first through groove from the open end of the first through groove, and then fix the pad on the side of the pressure block where the first through groove is opened, so that the connecting seat can be detachably installed at the corresponding position in the length direction of the steel cable; the fixing method of the connecting seat and the steel cable is simple and easy to install, which effectively ensures the convenience of installing the connecting seat on the steel cable, improves the assembly efficiency of the two, and thereby effectively improves the convenience of using the photovoltaic flexible bracket steel cable support unit.

[0028] In some embodiments, the connecting seat further includes an anti-slip strip, which is disposed in the first through slot, and a length direction of the anti-slip strip is parallel to a length direction of the through slot;

[0029] The anti-slip strip is provided with a second through-slot, and the opening of the second through-slot is opposite to the opening of the first through-slot;

[0030] Both ends of the anti-slip pressure strip in the length direction extend out of the corresponding side walls of the pressing block, and the pad is pressed on a side of the anti-slip pressure strip away from the second through groove.

[0031] In some embodiments, the anti-slip strip is an aluminum alloy strip, and the backing plate is a steel plate.

[0032] Through the photovoltaic flexible bracket steel cable support unit provided by the present application, due to the low hardness of aluminum alloy, an anti-slip strip made of aluminum alloy is added between the pad and the steel cable. When the pad is pressed on the side of the anti-slip strip away from the second through groove, the anti-slip strip will produce a certain deformation and fit with the surface of the steel cable, thereby effectively enhancing the roughness of the surface of the anti-slip strip, and then increasing the friction between it and the surface of the steel cable; in this way, the occurrence of the connecting seat sliding along the length direction of the steel cable due to force after being installed at the designated position on the steel cable can be effectively reduced, which helps to improve the connection stability between the corresponding photovoltaic flexible bracket steel cable support unit and the steel cable, that is, it helps to improve the stability of the overall structure of the corresponding photovoltaic flexible bracket.

[0033] In some embodiments, connecting ears are formed on the side walls of the pressing block corresponding to both ends of the first through-slot in the width direction. The connecting ears are arranged parallel to the backing plate and are located at one end of the first through-slot formed on the pressing block.

[0034] Both ends of the pad in the length direction are provided with connecting structures, and the connecting structures can detachably fix the pad and the corresponding connecting ears.

[0035] Through the photovoltaic flexible bracket cable support unit provided by this application, a pad is formed on the pressing block, and the corresponding connecting ear is connected to the two ends of the pad in the length direction by using a connecting structure, so that the pad can be detachably fixed on the side of the first through groove opened in the pressing block, which helps to improve the assembly convenience of the connecting seat, and thus effectively ensures the convenience of setting up the photovoltaic flexible bracket cable support unit and the corresponding photovoltaic flexible bracket.

[0036] On the other hand, the present application also provides a photovoltaic flexible bracket, comprising:

[0037] A steel cable support structure, comprising a plurality of steel cable support units for photovoltaic flexible supports as described above, and further comprising:

[0038] Steel cables, the steel cables comprising a load-bearing cable and a stabilizing cable disposed below the load-bearing cable;

[0039] The plurality of cable rods of the cable support structure are fixedly connected to the load-bearing cable or the stabilizing cable in pairs through a connecting seat, and the plurality of cable rods of the cable support structure are located in the same plane;

[0040] There are multiple steel cable support structures, and the multiple steel cable support structures are arranged at intervals along the length direction of the steel cable.

[0041] In some embodiments, the number of the photovoltaic flexible bracket is multiple:

[0042] Adjacent photovoltaic flexible supports are connected through a photovoltaic flexible support cable support unit. One end of the cable rod of the photovoltaic flexible support cable support unit is connected to the load-bearing cable of one photovoltaic flexible support through the corresponding fixing member, and the other end is connected to the stabilizing cable of the adjacent photovoltaic flexible support through the corresponding fixing member.

[0043] Compared with the prior art, the photovoltaic flexible bracket and steel cable support unit provided by this application have at least one of the following beneficial effects:

[0044] 1. In the present application, the main body of the cable rod is set to be in the shape of a circular tube, and the two ends of the circular tube body are respectively connected with the fixing parts formed by bending. The cable rod and the connecting seat are connected with the help of the open groove of the fixing part, so that the cable rod is fixed and installed between adjacent steel cables. On the one hand, since the main body of the cable rod is not subject to human intervention and the fixing parts are formed by bending the plate, the integrity is stronger, which makes the structure of the cable rod more durable and has better performance. At the same time, since the two ends of the circular tube body of the cable rod are sealed by the fixing parts, the cable rod production process does not require rust-proofing treatment of the interior of the circular tube body, the production process of the cable rod is more convenient, the production yield of the cable rod is higher, and it is convenient for mass production, which effectively reduces the production cost of the enterprise.

[0045] 2. In the present application, by opening a first through groove on the pressing block and providing a removable snap-fit ​​pad on one side of the first through groove formed on the pressing block, and at the same time providing an anti-slip strip in the first through groove, the connecting seat can be removably fixed at a designated position on the steel cable. The installation structure of the connecting seat and the corresponding steel cable is simple, which helps to improve the convenience and stability of the photovoltaic flexible bracket steel cable support unit when it is set between two steel cables.

[0046] 3. In this application, the anti-slip strip is an aluminum alloy strip. Since the aluminum alloy strip will be deformed to a certain extent when squeezed, its surface will fit the surface of the steel cable and the pad, effectively improving the roughness of its own surface, and then increasing the friction between it and the surface of the steel cable and the pad. The anti-slip effect is significant, effectively ensuring the stability of the photovoltaic flexible bracket cable support unit set on the corresponding photovoltaic flexible bracket.

[0047] 4. In this application, the anti-slip pressure strip can be separately placed between the pressure block and the pad; of course, the anti-slip pressure strip and the pad can also be formed as one piece, so that the pad is fixedly buckled on the corresponding side of the pressure block, and the stability of the connecting seat installed on the steel cable can be stably improved, effectively improving the assembly efficiency of the photovoltaic flexible bracket cable support unit and the steel cable, and effectively improving the construction stability of the corresponding photovoltaic flexible bracket.

[0059] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0060] To simplify the drawings, only the parts relevant to this application are schematically shown in each figure. They do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0061] Photovoltaic flexible supports are a common type of PV support, most commonly found in the three-cable flexible PV support format. This structure consists of a triangular cable truss structure with two upper load-bearing cables serving as the upper chord, a lower stabilizing cable serving as the lower chord, and a central cable rod. The lower stabilizing cable utilizes the central triangular cable truss to provide support for the two upper load-bearing cables. This controls the deflection of the module cables and ensures stable support for the PV modules on the load-bearing cables. Currently, the cables of three-cable flexible PV supports in related technologies mostly use round tubular rods with flattened ends.

[0062] However, the cable rods are made by flattening the ends of round tubes. On the one hand, the process is difficult to control, the cable rod yield is low, and the production cost of the enterprise is high. On the other hand, human intervention in this process destroys the structure of the round tube itself, resulting in poor structural strength of the finished cable rod and low durability, which affects the overall performance of the corresponding photovoltaic flexible bracket.

[0063] In one embodiment, referring to Figures 1 to 7 of the accompanying drawings of the specification, a photovoltaic flexible support cable support unit is disclosed, comprising a cable rod 1 and a connecting seat 2; wherein, referring to Figures 3 to 5, the cable rod 1 comprises a circular tubular body 11 and a fixing member 12, wherein the fixing member 12 is fixedly provided at each end of the length direction of the circular tubular body 11, and each fixing member 12 is provided with an open slot 124; and the connecting seat 2 is provided on the steel cable 100, and at least a portion of the connecting seat 2 extends into the open slot 124 and is fixedly connected to the fixing member 12 by a locking member, thereby connecting the cable rod 1 to the corresponding steel cable. Preferably, the fixing member 12 is fixedly connected to the circular tubular body 11 by welding. During actual assembly, after the connecting seat 2 is provided on the corresponding steel cable 100, the fixing piece 12 at the corresponding end in the length direction of the corresponding cable rod 1 is buckled onto the corresponding connecting seat 2, keeping the connecting seat 2 at least partially extended into the open groove, and then the fixing piece 12 and the connecting seat 2 are fixedly connected by the locking piece, thereby realizing the installation of the cable rod 1 on the corresponding steel cable 100. In other embodiments, the fixing piece 12 of the cable rod 1 can also be fixedly connected to the connecting seat 2 in advance by the locking piece, and then the connecting seat 2 can be fixed to the steel cable 100 after the project site, which can greatly save the labor cost and time cost of the project. Since the tubular main body 11 is not subject to human intervention during the production process of the cable rod 1, the structural durability of the cable rod 1 is higher, the bending resistance is stronger, and the performance is better; at the same time, the overall structure of the cable rod 1 is also more beautiful, the production is more convenient, and the production yield of the cable rod 1 is higher, which effectively saves the production cost of the enterprise. This is further elaborated below.

[0064] In one embodiment, based on the above-described embodiment, specifically, with reference to Figures 3 and 4, in this embodiment of the present application, any fixing member 12 includes a first fixing plate 121, a bottom plate 122, and a second fixing plate 123, wherein the first fixing plate 121 and the second fixing plate 123 are arranged in parallel and spaced apart, the bottom plate 122 is arranged between the first fixing plate 121 and the second fixing plate 123, and is arranged perpendicular to the first fixing plate 121 and the second fixing plate 123, and the two ends of the bottom plate 122 are respectively fixed to the first fixing plate 121 and the second fixing plate 123, so that the cross section of the fixing member 12 is U-shaped, that is, the first fixing plate 121, the bottom plate 122, and the second fixing plate 123 are jointly surrounded to form an open groove 124. At the same time, the two ends of the cylindrical body 11 are respectively connected to the corresponding fixing member 12, and are specifically located in the middle position of the corresponding bottom plate 122 in the thickness direction away from the corresponding first fixing plate 121 and the second fixing plate 123. The connecting seat 2 can be detachably fixed to the corresponding position on the steel cable 100 to install the corresponding cable rod 1, thereby fixing the steel cable support unit to the steel cable 100. In actual application, the first fixing plate 121 and the second fixing plate 123 of any fixing member 12 are detachably connected to the corresponding connecting seat 2 via a locking member, so that the corresponding end of the cable rod 1 is fixedly connected between the corresponding two steel cables 100.

[0065] During actual operation, the cable rod 1 can be pre-installed on the two connecting seats 2, and the two fixing parts 12 can be respectively buckled on the corresponding connecting seats 2, and then the corresponding fixing parts 12 can be fixedly connected to the corresponding connecting seats 2 with locking parts, thereby realizing the pre-installation of the cable rod 1. In the project, the connecting seat 2 can be directly installed in the relative position of the steel cable 100 to complete the fixed connection between the steel cable support unit and the steel cable 100, which can save installation time and reduce labor costs.

[0066] The fixings 12 at both ends of the cable rod 1 are formed by sequentially surrounding the first fixing plate 121, the bottom plate 122 and the second fixing plate 123. Since the structural form and manufacturing process of the fixings 12 are relatively simple, the manufacturing cost is low, it is convenient for mass production, and the scrap rate is low. In addition, the connection methods of the fixings 12 and the circular tubular body 11 are diverse and the process is simple, which helps to save the company's production costs. Moreover, compared with the related art that uses the process of flattening the two ends of the circular tube to form the cable rod 1, the cable rod 1 is formed in this way. The two ends of the cable rod 1 are sealed by the bottom plate 122 of the fixings 12. The circular tubular body 11 of the cable rod 1 is preferably a hollow structure. During the production process, it is only necessary to perform anti-rust treatment on the outer wall of the circular tubular body 11, and there is no need to perform anti-rust treatment on the inner wall of the circular tubular body 11. The anti-rust process is simple, easy to operate, and highly efficient, which reduces the process cost. At the same time, compared with angle steel or C-shaped steel, the circular tubular body 11 is Although the cross-sectional area of ​​the circular tubular main body 11 is similar to the previous two, its cross-sectional modulus is larger and its bending resistance is stronger; and, compared with the operation of connecting the L-shaped angle steel or C-shaped steel to the connecting seat 2 at the side, the U-shaped fixing part 12 is connected to the connecting seat 2 through the first fixing plate 121 and the second fixing plate 123. Because the force direction is different from that of the L-shaped angle steel or C-shaped steel, it overcomes the defect of eccentric force, effectively reduces the probability of bending moment generation, makes the structure of the cable rod 1 more durable, and effectively improves the structural stability of the corresponding photovoltaic flexible bracket.

[0067] Referring to Figures 3 and 4, in this embodiment of the present application, the fixing member 12 can be formed by bending a metal plate, that is, the first fixing plate 121, the bottom plate 122 and the second fixing plate 123 are integrally formed, which has a simple structure, is easy to process, and is beneficial to cost reduction for the enterprise; and it helps to improve the structural strength of the fixing member 12. Of course, the first fixing plate 121, the bottom plate 122 and the second fixing plate 123 can also be fixedly connected by other methods such as clamping and welding, and the two ends of the tubular body 11 can also be fixedly connected to the corresponding bottom plate 122 by welding, clamping, threading, etc., which are not listed here one by one, and the molding method of the fixing member 12 and the connection method of the tubular body 11 and the fixing member 12 should not be used as a limitation to the scope of protection of this application. In the embodiment of the present application, only the three are bent and formed, and the tubular body 11 is fixed to the corresponding position on the bottom plate 122 by welding as an example for explanation.

[0068] At the same time, in order to further improve the structural strength of the fixing member 12 and reduce the probability of local buckling of the fixing member 12 during use, in this embodiment of the present application, referring to Figure 5, a reinforcing rib plate 3 can be set between the first fixing plate 121 and the second fixing plate 123, and the reinforcing rib plate 3 is set to extend from the side of the bottom plate 122 along the length direction of the main body 11 in the direction away from the tubular main body 11 to adapt to the structural and dimensional requirements of fixing members 12 of more sizes and improve the structural strength of the cable rod 1.

[0069] 2 to 6 , in this embodiment of the present application, the connecting seat 2 is generally in the shape of a block. During operation, the fixing member 12 is buckled onto the connecting seat 2, and the first fixing plate 121 and the second fixing plate 123 of the fixing member 12 are respectively located on opposite sides of the connecting seat 2. In this embodiment of the present application, the first fixing plate 121 and the second fixing plate 123 of the fixing member 12 are respectively located on both sides of the thickness direction of the connecting seat 2, and the distance between the first fixing plate 121 and the second fixing plate 123 of any fixing member 12 is slightly greater than the thickness dimension of the connecting seat 2, so that the fixing member 12 can cooperate with the connecting seat 2; with reference to FIG4 , in the case where two cable rods 1 need to be installed at the same position of the connecting seat 2, the distance between the first fixing plate 121 and the second fixing plate 123 of the fixing member 12 of the outer cable rod 1 of the two cable rods 1 that need to be stacked should be slightly greater than the distance between the first fixing plate 121 and the second fixing plate 123 of the inner cable rod 1, so as to ensure stable cooperation at the connection node of the photovoltaic flexible bracket cable support structure.

[0070] In this embodiment of the present application, referring to FIG6 , two mounting holes 211 are formed through the middle of each connecting seat 2 along its thickness, and the locking member includes a locking bolt. During assembly, the threaded end of the locking bolt vertically penetrates the first fixing plate 121, the mounting hole 211 on the connecting seat 2, and the second fixing plate 123 in sequence, and engages with the threads of the three. The bolt is then tightened and fixed with a locking nut, thereby securing the corresponding end of the cable rod 1 to the corresponding connecting seat 2. Of course, the locking member can also be configured as a locking pin or other structural form. In the embodiments of the present application, there is no specific limitation on the configuration of the locking member.

[0071] At the same time, to facilitate the placement of the connector 2 on the steel cable 100 and ensure ease of installation, referring to FIG4 , in this embodiment of the present application, a through-hole is provided through the center of the connector 2, arranged along the thickness of the connector 2. During actual installation, the steel cable 100 sequentially passes through multiple through-holes along its length and is fixed relative to the corresponding connector 2, thereby achieving stable installation of multiple connectors 2 at corresponding positions along the length of the steel cable 100. Furthermore, during installation, the mounting direction of the fixing member 12 is perpendicular to the axial direction of the through-hole.

[0072] 2 , 6 and 7 , in order to facilitate the detachable connection between the steel cable 100 and each connecting seat 2, in this embodiment of the present application, the connecting seat 2 specifically includes a pressure block 21 and a pad 22; the mounting hole 211 is provided on the pressure block 21 and is located at one end of the width direction of the pressure block 21; a first through-groove 212 is provided on the side of the pressure block 21 in the width direction away from the mounting hole 211, the first through-groove 212 passes through the thickness direction of the pressure block 21 and is arranged parallel to the mounting hole 211, the first through-groove 212 is used to accommodate the steel cable 100; preferably, the first through-groove 212 is a U-shaped groove; the pad 22 is preferably set as a steel plate, and the pad 22 is detachably connected to the side of the pressure block 21 in the width direction where the first through-groove 212 is provided, so as to be combined with the inner wall of the first through-groove 212 to jointly install and fix the steel cable 100.

[0073] During the specific operation, the staff will insert the corresponding segment of the steel cable 100 into the first through groove 212 from the open end of the first through groove 212, and then fix the pad 22 to the side of the pressure block 21 where the first through groove 212 is opened, so that the connecting seat 2 can be detachably installed at the corresponding position in the length direction of the steel cable 100; the fixing method of the connecting seat 2 and the steel cable 100 is simple and easy to install, which effectively ensures the convenience of installing the connecting seat 2 on the steel cable 100, improves the assembly efficiency of the two, and thus effectively improves the convenience of using the photovoltaic flexible bracket cable support unit.

[0074] Further, referring to Figures 6 and 7, in order to ensure the stability of the connecting seat 2 when installed on the steel cable 100 and reduce the probability of the connecting seat 2 slipping along the length direction of the steel cable 100 after being installed on the steel cable 100, in this embodiment of the present application, an anti-slip strip 4 can be installed on the inner wall of the first through groove 212 to increase the friction between the steel cable 100 and the connecting seat 2 through the anti-slip strip 4.

[0075] In this embodiment of the present application, the length direction of the anti-slip bead 4 is arranged parallel to the length direction of the first through-slot 212; in the embodiment of the present application, the anti-slip bead 4 can be arranged separately relative to the connecting seat 2, for example, the anti-slip bead 4 can be detachably placed on the inner wall of the first through-slot 212, or the anti-slip bead 4 can be detachably placed on the side of the backing plate 22 at a position corresponding to the first through-slot 212. Of course, the anti-slip bead 4 can also be arranged integrally with the connecting seat 2, for example, the anti-slip bead 4 can be fixedly placed on the side of the backing plate 22 at a position corresponding to the first through-slot 212, and a second through-slot 41 is opened on the side of the anti-slip bead 4 facing away from the backing plate 22, that is, the opening of the second through-slot 41 is arranged opposite to the opening of the first through-slot 212. During the specific operation, after the steel cable 100 is coaxially embedded in the first through groove 212 on the pressure block 21, the pad 22 is fixedly buckled on the corresponding side of the pressure block 21, so that the steel cable 100 is fixedly embedded in the second through groove 41, and a stable connection between the connecting seat 2 and the corresponding steel cable 100 can be achieved; since the anti-slip strip 4 and the pad 22 are integrated into one, while improving the assembly efficiency of the photovoltaic flexible bracket cable support unit and the steel cable 100, it can also effectively ensure the stability of the photovoltaic flexible bracket cable support unit set on the corresponding photovoltaic flexible bracket, and the design is ingenious and practical.

[0076] In the embodiment of the present application, there are various ways to fix the anti-slip strip 4 and the pad 22, such as fixed clamping, welding, etc. Appropriate processes can be selected according to the molding materials of the anti-slip strip 4 and the pad 22, and they will not be listed one by one here.

[0077] To maximize the anti-slip effect, in this embodiment of the present application, the anti-slip bead 4 is preferably configured as an aluminum alloy bead. Because aluminum alloy has a low hardness, after the backing plate 22 and the pressure block 21 are fixedly fastened, the aluminum alloy bead deforms due to compression and adheres to the surface of the steel cable 100, thereby enhancing the surface roughness of the anti-slip bead 4 and increasing the friction between it and the surface of the steel cable 100. Compared with anti-slip bead 4 made of other hard materials, the aluminum alloy bead has a better anti-slip effect. The backing plate 22 is made of steel plate, which overcomes the defect of aluminum alloy's easy deformation, enhances the structural strength of the connecting seat 2, and makes the connection more secure and reliable.

[0078] In addition, during actual production, the length of the anti-slip strip 4 can be set to be larger than the length of the first through groove 212; in actual operation, when the anti-slip strip 4 is padded in the first through groove 212 along its own length direction, the two ends of the anti-slip strip 4 in the length direction extend out of the corresponding side walls of the pressure block 21; compared with the setting method in which the two end faces of the anti-slip strip 4 must be kept flush with the corresponding side walls of the pressure block 21, this setting method does not require precise positioning of the anti-slip strip 4 and the pressure block 21 during installation, which reduces the production and installation difficulty of the connecting seat 2, and helps to ensure the production and use convenience of the photovoltaic flexible bracket cable support structure.

[0079] In addition, in order to improve the convenience of buckling the pad 22 and the pressure block 21, and to realize the rapid construction of the photovoltaic flexible bracket cable support structure and the corresponding photovoltaic flexible bracket, in this embodiment of the present application, the side walls corresponding to the first through groove 212 at both ends in the width direction of the pressure block 21 are formed with connecting ears 213, and the connecting ears 213 are arranged parallel to the pad 22 and are located at one end of the first through groove 212 formed on the pressure block 21; both ends of the pad 22 in the length direction are provided with connecting structures. After the pad 22 and the pressure block 21 are buckled together, the pad 22 and the corresponding connecting ears 213 can be detachably fixed through the connecting structure to realize the assembly of the connecting seat 2.

[0080] In the embodiment of the present application, the connection structure can be configured as a fastening bolt and a fixing nut. When the backing plate 22 and the pressure block 21 are engaged, the threaded end of the fastening bolt sequentially penetrates the corresponding end of the backing plate 22 and the corresponding connecting ear 213, and is then tightened by the fixing nut, thereby achieving detachable fixation of the backing plate 22 and the pressure block 21. Of course, the connection structure can also be configured in other forms, such as a snap-fit ​​connection, a hook connection, etc. In the embodiment of the present application, the configuration form of the connection structure is not specifically limited.

[0081] The present technical solution is further described below with reference to a photovoltaic module 400 and a steel cable 100. In one embodiment, referring to Figures 1 to 7 of the accompanying drawings, a photovoltaic flexible support is disclosed, comprising a column, a beam disposed at the top of the column, a steel cable 100, and a plurality of steel cable support structures. The column supports the beam, and the steel cables 100 extend through the beam and between adjacent columns to support the photovoltaic module 400. Specifically, the plurality of steel cables 100 include two load-bearing cables 200 and a stabilizing cable 300 disposed below the load-bearing cables 200. The steel cable support structures support the steel cables 100, and each of the steel cable support structures includes a plurality of photovoltaic flexible support cable support units as described in any of the above embodiments. The steel cable support structures are spaced apart along the length of the steel cables 100. The plurality of cable rods 1 of any of the steel cable support structures are fixedly connected in pairs to the load-bearing cables 200 or the stabilizing cables 300 via a connecting seat 2, and the plurality of cable rods 1 of any of the steel cable support structures are located in the same plane. Preferably, the steel cable support structure is arranged in a triangular shape, including three cable rods 1 and three connecting seats 2. The three cable rods 1 intersect end to end in sequence and are fixedly connected to the load-bearing cable 200 or the stabilizing cable 300 through the connecting seats 2. The steel cable support structure effectively utilizes the stability principle of the triangle, increases the wind resistance of the photovoltaic flexible bracket, and has better stability.

[0082] As is well known, photovoltaic flexible supports are usually built in multiple rows, that is, the number of photovoltaic flexible supports is multiple rows. During actual operation, adjacent rows of photovoltaic flexible supports are connected by a photovoltaic flexible support cable support unit. Specifically, one end of the cable rod 1 of the photovoltaic flexible support cable support unit is connected to the corresponding load-bearing cable 200 of a corresponding photovoltaic flexible support through a corresponding fixing member 12, and the other end is connected to the stabilizing cable 300 of the adjacent row of photovoltaic flexible supports through a corresponding fixing member 12, thereby connecting multiple rows of flexible photovoltaic supports to each other, and further enhancing stability and wind resistance. Preferably, the cable support unit connecting two adjacent rows of flexible photovoltaic supports is correspondingly arranged with the cable support structure on the corresponding flexible photovoltaic support, and the cable support unit and the cable support structure on the corresponding flexible photovoltaic support share a connecting member 2, and the cable support unit connecting two adjacent rows of flexible photovoltaic supports and the cable support structure on the corresponding flexible photovoltaic support are located in the same plane. It can be understood that the number of cable support units connecting two adjacent rows of flexible photovoltaic supports is correspondingly set to multiple, and is arranged in sequence along the length direction of the flexible photovoltaic support.

[0083] At the same time, the photovoltaic modules 400 are usually provided in multiple pieces, and the multiple photovoltaic modules 400 are evenly spaced along the length direction of the steel cable 100 and can be detachably fixed above the two load-bearing cables 200.

[0084] The implementation principle of this embodiment of the present application is as follows: in actual operation, after the multiple steel cables 100 of the corresponding photovoltaic flexible support are erected, the connecting seat 2 is installed along the length direction of each steel cable 100. Specifically, after the corresponding segment of the steel cable 100 is inserted into the first through groove 212 from the open end of the first through groove 212, the pad 22 is fixedly buckled on the side of the pressure block 21 where the first through groove 212 is opened, so that the corresponding connecting seat 2 can be detachably installed at the corresponding position in the length direction of the steel cable 100; after the corresponding positions of two adjacent steel cables 100 are installed with the connecting seat 2, the cable rod 1 is placed between the two steel cables 100, and the fixing members 12 at both ends of the cable rod 1 are respectively buckled on the corresponding connecting seats 2 on the two steel cables 100, and then the corresponding fixing members 12 are fixedly connected to the corresponding connecting seats 2 with the locking bolts, so that the corresponding cable rod 1 can be supported and connected between the two steel cables 100. This cycle is repeated until the installation operation of all cable rods 1 is completed. Afterwards, the photovoltaic components 400 are placed one by one along the length direction of the steel cables 100 on the two upper steel cables 100, i.e., the load-bearing cables 200, and the side pressure plates at the edges of each photovoltaic component 400 are connected using connecting structures such as snaps. In this way, the photovoltaic components 400 can be detachably installed on the load-bearing cables 200, that is, the construction of the corresponding photovoltaic flexible bracket is realized.

[0085] The cable rod 1 is set by assembling the circular tubular body 11 and the U-shaped fixing piece 12, and the cable rod 1 is fixedly installed between the two steel cables 100 with the help of the fixing piece 12; on the one hand, the connection method of the fixing piece 12 and the circular tubular body 11 is diverse, and the process is simple, so that the production yield of the cable rod 1 is high and it is convenient for mass production; on the other hand, since the fixing piece 12 is U-shaped, it is connected to the connecting seat 2 through the first fixing plate 121 and the second fixing plate 123 on both sides. Compared with the operation of connecting the cable rod 1 of the traditional L-shaped angle steel or C-shaped steel structure to the connecting seat 2 at the side, the cable rod 1 of the present application is easy to use during use. Due to the different force directions, the defect of eccentric force is overcome, and the probability of bending moment generation is effectively reduced, so that the structural durability of the cable rod 1 is stronger, thereby improving the structural stability of the corresponding photovoltaic flexible bracket; at the same time, the circular tubular body 11 of the cable rod 1 maintains the original circular tubular structure of the material, and the overall appearance is beautiful; moreover, compared with the related technology that adopts the process of flattening the two ends of the circular tube to form the cable rod 1, the cable rod 1 of the present application has two ends of the circular tubular body 11 closed, and the production process does not require the inner wall of the circular tubular body 11 to be rust-proofed. The rust-proof process is simple and easy to operate, which effectively reduces the production cost of the enterprise.

[0086] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be considered as the scope of protection of the present application.
