Description

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] Photovoltaic brackets are an important part of photovoltaic power generation systems. To meet market demand, their structures are diverse. In recent years, photovoltaic flexible brackets have been widely used in production and life due to their simple and light structure, low cost, strong pre-assembly, large span and flexible construction.

[0003] In the related art, the commonly used photovoltaic flexible brackets are mostly three-cable flexible photovoltaic brackets, that is, the main body is composed of two load-bearing steel cables at the top, a stabilizing steel cable at the bottom, and a plurality of cable rods connected between the three steel cables, which are used to stably support the photovoltaic components. At present, the cable rods in the three-cable flexible photovoltaic brackets on the market are mostly made by flattening the two ends of the round tube rods; however, this manufacturing process has a low cable rod yield rate and high production costs, and the process destroys the structural form of the round tube itself due to manual intervention, which makes the cable rod structure durable and poor in use. There is room for improvement. Utility Model Content

[0004] 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.

[0005] The technical solutions provided by this application are as follows:

[0006] In one aspect, the present application provides a photovoltaic flexible support cable support unit, comprising: a cable rod and a connecting seat;

[0007] The cable rod comprises a circular tubular body for supporting adjacent steel cables;

[0008] A fixing piece is fixedly provided at each end of the circular tubular body, and an opening groove is provided on any of the fixing pieces;

[0009] The connecting seat at least partially extends into the opening groove and is fixedly connected to the fixing member through a locking member to connect the cable rod to the steel cable.

[0010] Through a photovoltaic flexible bracket steel cable support unit provided by the present application, the main body of the cable rod is set in a circular tube shape, 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 is connected to the corresponding end of the cable rod through the open groove, so that the cable rod can be installed on the corresponding steel cable.

[0011] 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, the production is more convenient, and the production yield of the cable rod is higher, which effectively saves the production cost of the enterprise.

[0015] A 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 fixings are respectively buckled on the corresponding connecting seats on the two steel cables, and then the corresponding fixings 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 that uses a process of flattening the two ends of a round tube to form a cable rod, when this method is used to form a cable rod, 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 rust prevention, and the rust prevention process is simple, easy to operate, and highly efficient, which reduces the process cost; and, 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 cable rod more durable and having better performance, 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 a variety of 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.

[0016] In some embodiments, a reinforcing rib plate is provided between the first fixing plate and the second fixing plate.

[0017] Through the photovoltaic flexible bracket cable support unit provided by the present application, the reinforcing rib plate is used to improve the structural strength of the fixing part, reduce the probability of local buckling of the fixing part during use, and help to further extend the service life of the cable rod, thereby improving its performance.

[0018] In some embodiments, the locking member comprises a locking bolt;

[0019] The threaded end of the locking bolt vertically penetrates the first fixing plate, the connecting seat and the second fixing plate in sequence, and is threadably matched with the three.

[0020] The first fixing plate, the bottom plate and the second fixing plate are integrally bent and formed.

[0021] A photovoltaic flexible bracket cable support unit provided in the present 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.

[0022] 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.

[0023] In some embodiments, the connection seat includes a pressing block and a backing plate;

[0024] A first through slot is formed on one side of the pressing block in a thickness direction thereof, and the pad is detachably connected to the side of the pressing block where the first through slot is formed;

[0025] The fixing member is connected to one end of the pressing block away from the backing plate.

[0026] A photovoltaic flexible bracket steel cable support unit provided by the present application utilizes a pad and a first through groove formed on a pressing 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 operations, the staff will embed the corresponding segment of the steel cable into the first through groove from the opening end of the first through groove, and then fix the pad on the side of the pressing 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 use of the photovoltaic flexible bracket steel cable support unit.

[0027] 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;

[0028] The anti-slip pressure 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] In some embodiments, the anti-slip strip is an aluminum alloy strip, and the backing plate is a steel plate.

[0031] A photovoltaic flexible bracket cable support unit provided by the present application has a low hardness of aluminum alloy, and 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 slippage along the length direction of the steel cable due to force after the connecting seat is 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 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.

[0032] 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, and the connecting ears are arranged parallel to the pad and located at one end of the first through slot formed on the pressing block;

[0033] 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.

[0034] Through the photovoltaic flexible bracket steel cable support unit provided by the present application, a pad is formed on the pressing block, and a connecting structure is used to connect the corresponding connecting ears and the two ends of the pad in the length direction, so that the pad can be detachably fixed on the side of the first through groove 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 steel cable support unit and the corresponding photovoltaic flexible bracket.

[0035] On the other hand, the present application also provides a photovoltaic flexible bracket, comprising:

[0036] A steel cable support structure, the steel cable support structure comprising a plurality of photovoltaic flexible bracket steel cable support units as described above, and further comprising:

[0037] A steel cable, the steel cable comprising a load-bearing cable and a stabilizing cable disposed below the load-bearing cable;

[0038] 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 in the same plane;

[0039] 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.

[0040] In some embodiments, the number of the photovoltaic flexible bracket is multiple:

[0041] Adjacent photovoltaic flexible brackets are connected through a photovoltaic flexible bracket cable support unit. One end of the cable rod of the photovoltaic flexible bracket cable support unit is connected to the load-bearing cable of one photovoltaic flexible bracket through the corresponding fixing member, and the other end is connected to the stabilizing cable of the adjacent photovoltaic flexible bracket through the corresponding fixing member.

[0042] Compared with the prior art, the photovoltaic flexible bracket and the steel cable support unit provided in the present application have at least one of the following beneficial effects:

[0043] 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 to the fixing parts formed by bending, and the cable rod and the connecting seat are connected with the help of the open groove of the fixing part, so as to realize the fixed installation of the cable rod 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, so that the structure of the cable rod has higher durability and 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 production process of the cable rod does not need to carry out rust-proof treatment on the inside of the circular tube body, the production process of the cable rod is more convenient, the production yield of the cable rod is higher, it is convenient for mass production, and the production cost of the enterprise is effectively reduced.

[0044] 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 fixedly installed 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.

[0045] 3. In the present 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.

[0046] 4. In the present 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 integrally, so that when the pad is fixedly buckled on the corresponding side of the pressure block, the stability of the connecting seat installed on the steel cable can be stably improved, thereby effectively improving the assembly efficiency of the photovoltaic flexible bracket steel cable support unit and the steel cable, and effectively improving the construction stability of the corresponding photovoltaic flexible bracket.

[0058] 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 ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0059] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0060] As a commonly used type of photovoltaic bracket, the photovoltaic flexible bracket is commonly seen in the form of three-cable flexible photovoltaic bracket, that is, the main body is composed of two upper load-bearing cables as the upper chord beam, a lower stabilizing cable as the lower chord beam, and a middle cable rod to form a triangular cable truss. The lower stabilizing cable uses the middle triangular cable truss to provide support for the two upper load-bearing cables, thereby controlling the deflection of the component cable and achieving stable support of the photovoltaic component on the load-bearing cable. At present, the three-cable flexible photovoltaic bracket in the related technology mostly adopts the structural form of round tube rods with flattened ends.

[0061] However, the cable rod is made by flattening the two ends of the round tube. 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.

[0062] In one embodiment, referring to the accompanying drawings of the specification Figures 1 to 7 , discloses a photovoltaic flexible support cable support unit, including a cable rod 1 and a connecting seat 2; wherein, with reference to Figures 3 to 5The cable rod 1 includes a tubular body 11 and a fixing member 12, wherein the fixing member 12 is fixedly provided at each end of the tubular body 11 in the length direction, and an opening groove 124 is provided on any fixing member 12; and the connecting seat 2 is arranged on the steel cable 100, and at least a portion of the connecting seat 2 extends into the opening groove 124, and is fixedly connected to the fixing member 12 through a locking member, thereby connecting the cable rod 1 to the corresponding steel cable. Preferably, the fixing member 12 is fixedly connected to the tubular body 11 by welding. During actual assembly, after the connecting seat 2 is arranged on the corresponding steel cable 100, the fixing member 12 at the corresponding end in the length direction of the corresponding cable rod 1 is buckled onto the corresponding connecting seat 2, and the connecting seat 2 is kept at least partially extended into the opening groove, and then the fixing member 12 and the connecting seat 2 are fixedly connected through a locking member, thereby realizing the installation of the cable rod 1 on the corresponding steel cable 100. In other embodiments, the fixing member 12 of the cable rod 1 can also be pre-fixed with the connecting seat 2 through a locking member, and 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 body 11 is not subject to human intervention during the production process of the cable rod 1, the cable rod 1 has higher structural durability, stronger bending resistance, and better performance; at the same time, the overall structure of the cable rod 1 is more beautiful, 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 explained below.

[0063] In one embodiment, based on the above embodiments, specifically, referring to Figure 3 and Figure 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 circular tubular 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 is detachably fixed to the corresponding position on the steel cable 100 to install the corresponding cable rod 1, so as to fix the steel cable support unit to the steel cable 100. In practical applications, 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 through a locking member, so that the corresponding end of the cable rod 1 is fixedly connected between the corresponding two steel cables 100.

[0064] 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 snapped 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 at 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.

[0065] 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 production cost of the enterprise. 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, the defect of eccentric force is overcome, the probability of generating bending moment is effectively reduced, and the structural durability of the cable rod 1 is stronger, which effectively improves the structural stability of the corresponding photovoltaic flexible bracket.

[0066] Reference Figure 3 and Figure 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 formed in one piece, which has a simple structure, is easy to process, and is conducive to cost reduction for enterprises; 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, threaded connection, 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 on the protection scope of this application. In the implementation 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.

[0067] 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, reference is made to Figure 5 A reinforcing rib plate 3 can be arranged between the first fixing plate 121 and the second fixing plate 123, and the reinforcing rib plate 3 is arranged to extend from one side of the bottom plate 122 along the length direction of the main body 11 in a direction away from the tubular main body 11, so as 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.

[0068] Reference Figures 2 to 6 In this embodiment of the present application, the connecting seat 2 is generally in a block-shaped structure. During specific 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 two 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 larger than the thickness dimension of the connecting seat 2, so that the fixing member 12 can cooperate with the connecting seat 2; refer to Figure 4 In the case where two cable rods 1 need to be installed at the same position of the connecting seat 2, among the two cable rods 1 that need to be stacked, 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 should be slightly larger than the distance between the first fixing plate 121 and the second fixing plate 123 of the inner cable rod 1 to ensure stable cooperation at the connection node of the photovoltaic flexible bracket cable support structure.

[0069] In this embodiment of the present application, refer to Figure 6 , two mounting holes 211 are formed in the middle of any connecting seat 2 along its thickness direction, 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 is threadedly matched with the three, and then is locked and fixed by a locking nut, so that the corresponding end of the cable rod 1 can be fixed on the corresponding connecting seat 2. Of course, the locking member can also be set as a locking pin or other structural form. In the embodiment of the present application, there is no specific limitation on the setting form of the locking member.

[0070] At the same time, in order to realize the setting of the connecting seat 2 on the steel cable 100 and ensure the convenience of installing the connecting seat 2 on the steel cable 100, refer to Figure 4In this embodiment of the present application, a through hole is formed in the middle of the connection seat 2, and the through hole is arranged along the thickness direction of the connection seat 2. During actual installation, the steel cable 100 passes through multiple through holes in sequence along its length direction, and is relatively fixed to the corresponding connection seat 2, so as to achieve stable installation of multiple connection seats 2 at corresponding positions in the length direction of the steel cable 100. In addition, during installation, the installation direction of the fixing member 12 is perpendicular to the axial direction of the through hole.

[0071] Reference Figure 2 , Figure 6 and Figure 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 pressing block 21 and a pad 22; the mounting hole 211 is opened on the pressing block 21 and is located at one end of the pressing block 21 in the width direction; the pressing block 21 is provided with an opening of a first through groove 212 on the side away from the mounting hole 211 in the width direction, the first through groove 212 runs through the thickness direction of the pressing block 21 and is arranged parallel to the mounting hole 211, and 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 pressing block 21 in the width direction where the first through groove 212 is opened, so as to be combined with the inner wall of the first through groove 212 to jointly install and fix the steel cable 100.

[0072] During the specific operation, the staff will embed 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 first through groove 212 opened on the pressure block 21, 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 use of the photovoltaic flexible bracket cable support unit.

[0073] Further, see Figure 6 and Figure 7 In order to ensure the stability of the connection seat 2 installed on the steel cable 100 and reduce the probability of the connection 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 provided on the inner wall of the first through groove 212 to increase the friction between the steel cable 100 and the connection seat 2 through the anti-slip strip 4.

[0074] In this embodiment of the present application, the length direction of the anti-skid strip 4 is arranged parallel to the length direction of the first through groove 212; in the embodiment of the present application, the anti-skid strip 4 can be arranged separately relative to the connecting seat 2, for example, the anti-skid strip 4 is detachably arranged on the inner wall of the first through groove 212, or the anti-skid strip 4 is detachably arranged on the side of the backing plate 22 corresponding to the position of the first through groove 212. Of course, the anti-skid strip 4 can also be arranged integrally with the connecting seat 2, for example, the anti-skid strip 4 is fixedly arranged on the side of the backing plate 22 corresponding to the position of the first through groove 212, and the side of the anti-skid strip 4 facing away from the backing plate 22 is provided with a second through groove 41, that is, the opening of the second through groove 41 is arranged opposite to the opening of the first through groove 212. In specific operations, 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 pressure strip 4 and the pad 22 are integrally arranged, 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.

[0075] In the implementation manner 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., and an appropriate process can be selected according to the molding materials of the anti-slip strip 4 and the pad 22, which will not be listed here one by one.

[0076] In order to ensure the anti-skid effect as much as possible, in this embodiment of the present application, preferably, the anti-skid strip 4 is set as an aluminum alloy strip; because the hardness of aluminum alloy is low, after the pad 22 and the pressure block 21 are fixedly buckled, the aluminum alloy strip is deformed to a certain extent due to extrusion and fits with the surface of the steel cable 100, thereby enhancing the roughness of the surface of the anti-skid strip 4 and increasing the friction between it and the surface of the steel cable 100. Compared with the anti-skid strip 4 made of other hard materials, the aluminum alloy strip has a better anti-skid effect. The pad 22 is made of steel plate, which overcomes the defect of easy deformation of aluminum alloy, enhances the structural strength of the connecting seat 2, and makes the connection more firm and reliable.

[0077] 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 to the setting method in which the two end surfaces 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 convenience of production and use of the photovoltaic flexible bracket cable support structure.

[0078] In addition, in order to improve the convenience of buckling the pad 22 and the pressing block 21, and 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, connecting ears 213 are formed on the side walls at both ends of the width direction of the first through groove 212 on the pressing block 21. 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 pressing block 21; connecting structures are arranged at both ends of the length direction of the pad 22. After the pad 22 and the pressing block 21 are buckled, 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.

[0079] In the embodiment of the present application, the connection structure can be set as a fastening bolt and a fixing nut. When the backing plate 22 and the pressure block 21 are buckled, the threaded end of the fastening bolt sequentially penetrates the corresponding end of the backing plate 22 and the corresponding connection ear 213, and then is locked by the fixing nut, so that the backing plate 22 and the pressure block 21 can be detachably fixed. Of course, the connection structure can also be set in other forms, such as buckle clamping, hook hooking, etc. In the embodiment of the present application, there is no specific limitation on the setting form of the connection structure.

[0080] Next, the present technical solution is further described in combination with the photovoltaic module 400 and the steel cable 100: In one embodiment, referring to the accompanying drawings of the specification Figures 1 to 7 , discloses a photovoltaic flexible support, including a column, a crossbeam arranged at the top of the column, a steel cable 100, and a plurality of steel cable support structures, wherein the column is used to support the crossbeam, the steel cable 100 passes through the crossbeam and extends between adjacent columns, and is used to support a photovoltaic module 400, specifically, the plurality of steel cables 100 include two load-bearing cables 200 and a stabilizing cable 300 arranged below the load-bearing cable 200, the steel cable support structure is used to support the steel cables 100, and each steel cable support structure includes a plurality of photovoltaic flexible support steel cable support units as described in any of the above embodiments, and a plurality of steel cable support structures are arranged at intervals along the length direction of the steel cables 100. The plurality of cable rods 1 of any steel cable support structure are fixedly connected to the load-bearing cable 200 or the stabilizing cable 300 in pairs through a connecting seat 2, and the plurality of cable rods 1 of any steel cable support structure 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.

[0081] As is known to all, photovoltaic flexible brackets are usually built in multiple rows, that is, the number of photovoltaic flexible brackets is multiple rows. In actual operation, adjacent rows of photovoltaic flexible brackets are connected by a photovoltaic flexible bracket cable support unit. Specifically, one end of the cable rod 1 of the photovoltaic flexible bracket cable support unit is connected to the corresponding load-bearing cable 200 of a corresponding photovoltaic flexible bracket through a corresponding fixing member 12, and the other end is connected to the stabilizing cable 300 of the adjacent row of photovoltaic flexible brackets through a corresponding fixing member 12, so that multiple rows of flexible photovoltaic brackets are connected to each other, and the stability and wind resistance are further enhanced. Preferably, the cable support unit connecting two adjacent rows of flexible photovoltaic brackets is set correspondingly to the cable support structure on the corresponding flexible photovoltaic bracket, and the cable support unit and the cable support structure on the corresponding flexible photovoltaic bracket share a connecting member 2, and the cable support unit connecting two adjacent rows of flexible photovoltaic brackets and the cable support structure on the corresponding flexible photovoltaic bracket are located in the same plane. It can be understood that the number of cable support units connecting two adjacent rows of flexible photovoltaic brackets is set to multiple, and they are arranged in sequence along the length direction of the flexible photovoltaic bracket.

[0082] Meanwhile, 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 .

[0083] 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 bracket 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 embedded 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 first through groove 212 of the pressing block 21, so as to realize the detachable installation of the corresponding connecting seat 2 at the corresponding position of the length direction of the steel cable 100; after the corresponding positions of the 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 fixings 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 fixings 12 are fixedly connected with the corresponding connecting seats 2 with the locking bolts, so as to realize the support and connection of the corresponding cable rod 1 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 on the two upper steel cables 100, i.e., the load-bearing cables 200, along the length direction of the steel cables 100, 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, i.e., the construction of the corresponding photovoltaic flexible bracket is realized.

[0084] The cable rod 1 is set by assembling the circular tubular body 11 and the U-shaped fixing member 12, and the fixing member 12 is used to fix the cable rod 1 between the two steel cables 100; on the one hand, the fixing member 12 and the circular tubular body 11 are connected in various ways, 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 member 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 two ends of the circular tubular body 11 of the cable rod 1 of the present application are closed, and the inner wall of the circular tubular body 11 does not need to be rust-proofed during the production process. The rust-proof process is simple and easy to operate, which effectively reduces the production cost of the enterprise.

[0085] It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred implementation 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 principle of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
