Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic supports, and in particular to a photovoltaic support steel cable connection structure. Background Art

[0002] Photovoltaic power generation, as a clean, safe and renewable energy technology, is developing rapidly around the world. However, in complex terrain or special scenarios, the application of traditional rigid photovoltaic brackets is limited. Flexible photovoltaic brackets came into being, and with their large span, high adaptability and flexible installation characteristics, they provide a better solution for photovoltaic power generation projects. Unlike traditional rigid photovoltaic brackets, flexible photovoltaic brackets adopt a tension structure system design with fixed ends, and use steel cables as component support members to form a large-span photovoltaic component support structure. Flexible photovoltaic brackets are usually used in conjunction with steel cable connection structures. The two ends of the steel cable are connected to the bracket by fastening components. This design can effectively enhance the stability of the system, improve the wind and earthquake resistance of photovoltaic power stations, and ensure the safety and long-term reliability of photovoltaic systems under various environmental conditions.

[0003] The photovoltaic bracket cable connection structure in the prior art, such as a flexible photovoltaic bracket cable structure and a method of use disclosed in the Chinese patent application document with publication number CN119276194A, is a flexible photovoltaic bracket cable structure. The flexible photovoltaic bracket cable structure is provided with a third fixing block, a third cable and a support assembly. After the photovoltaic panel is fixed on the first cable and the second cable by the buckle assembly, the third fixing block, the third cable and the support assembly can cooperate to support the lower end of the photovoltaic panel, so that the force of the first cable and the second cable can be reduced, thereby increasing the service life of the first cable and the second cable, and also making the photovoltaic panel more stable during installation, thereby reducing the shaking amplitude of the photovoltaic panel. When the photovoltaic panel is fixed, after the second wedge block contacts the first wedge block, the second wedge block squeezes the first wedge block to move, and then the extrusion plate can be stably approached to the card board with the cooperation of the limit groove and the limit block, and then the photovoltaic panel can be fixed with the cooperation of the card board, making the installation of the photovoltaic panel more convenient and quick.

[0004] However, during use of the cable structure of the above-mentioned flexible photovoltaic bracket in the prior art, the entire steel cable is fixed to the support frame as a whole through a fixing block. Since the steel cable is formed by twisting multiple steel wire ropes, when one of the steel wire ropes inside the twisted structure is broken or damaged, it is easy to cause the fixing force of the fixing block on the entire steel cable to decrease, and the fixing reliability is reduced, thereby causing the fixing point to loosen or fail, and even causing the steel cable to fall off, endangering the safety of the photovoltaic bracket. Summary of the invention

[0005] The present invention provides a photovoltaic support cable connection structure, aiming to solve the problem in the related art that when a single steel wire rope is broken or lost, the fixing force of the fixing block on the entire steel cable is easily reduced.

[0006] The photovoltaic support cable connection structure provided by the present invention adopts the following technical solution: A photovoltaic support cable connection structure is used to install the end of the cable on a support frame, comprising: A fixing seat, the fixing seat is arranged on the supporting frame, the fixing seat has a conical chamber which is larger on the left and smaller on the right, the left and right ends of the conical chamber are respectively connected to the outside, and form an outgoing end for passing the steel wire rope and an incoming end for passing the steel cable; A fastener, the fastener is assembled on the fixing seat in a left-right movable manner, the fastener comprises a tapered plug matched with the tapered chamber, and a plurality of dividing rods arranged on the left end face of the tapered plug, an extrusion space is left between the outer wall of the tapered plug and the inner wall of the tapered chamber, the steel cable penetrates into the tapered chamber from the insertion end, and is divided into a plurality of steel cables to pass through the extrusion space, and then passes through the tapered chamber through the exit end, and each of the dividing rods is inserted between two adjacent steel cables to separate the steel cables in the steel cable; A locking piece is arranged on a fixing seat and connected to a fastener, and is used to drive the fastener to move rightward to push the conical plug into the conical chamber, so that the conical plug cooperates with the conical chamber to compress and fix the steel wire rope.

[0007] By adopting the above technical scheme, fasteners and locking pieces are arranged on the fixing seat, the ends of the twisted steel cables are spread out to form a plurality of steel wire ropes, and the plurality of steel wire ropes are allowed to enter the extrusion space formed between the conical plug and the conical chamber, the steel wire ropes are independently separated by the dividing rod, and the conical plug is pushed into the conical chamber by the locking piece, so that the conical plug cooperates with the conical chamber to compress and fix the steel wire ropes, thus ensuring that each steel wire rope exists independently in the extrusion space and is independently subjected to the extrusion force from the outer wall of the conical plug and the inner wall of the conical chamber, thereby independently fixing each steel wire rope, even if one steel wire rope is broken or damaged, it will not affect the fixing effect of other steel wire ropes, thus avoiding the overall fixing failure due to the breakage of a single steel wire rope, and improving the reliability and safety of the entire steel cable connection mechanism.

[0008] Furthermore, the locking member includes a locking ring installed on the fixing seat and located on the left side of the fastener, and a locking elastic member connected between the locking ring and the fastener, wherein the locking elastic member is used to apply elastic force to the fastener to move the fastener to the right.

[0009] By adopting the above technical solution, the elastic force locking method can provide continuous pressure to prevent loosening, and it is quick and easy.

[0010] Furthermore, the fastener also includes a connecting ring connected between the plurality of partition rods and extending along the circumference of the tapered plug, and the plurality of locking elastic members are distributed along the circumference of the connecting ring between the connecting ring and the locking ring.

[0011] Furthermore, the photovoltaic bracket cable connection structure also includes a driving gear rotatably mounted on a fixed seat, and the locking ring is provided with a driven gear cooperating with the driving gear and a clamping groove cooperating with the connecting ring. The connecting ring is guided left and right by a clamping block and is assembled on the locking ring in a circumferentially limited manner along the connecting ring so as to rotate synchronously with the locking ring.

[0012] The above technical solution is used to realize the rotation of the fastener. When the fastener rotates, it can drive the wire rope to rotate around the central axis of the conical plug through the rope buckle to further untie the twisted part of the steel cable, which is convenient for subsequent tension adjustment.

[0013] Furthermore, the fixing seat also has a horizontal pipe section located on the right side of the conical chamber, and the penetration end of the conical chamber is connected to the outside through the horizontal pipe section. The photovoltaic bracket cable connection structure also includes a fixing mechanism installed at the horizontal pipe section, and the fixing mechanism includes a plurality of arc-shaped locking pieces distributed circumferentially along the horizontal pipe section, and a driver corresponding to each arc-shaped locking piece for driving each arc-shaped locking piece to move radially along the horizontal pipe section. Each of the arc-shaped locking pieces is in an arc shape and has a pressing surface for fitting the outer surface of the steel cable. When the driver drives the arc-shaped locking piece to approach the steel cable radially along the horizontal pipe section, the pressing surface of the arc-shaped locking piece can abut the outer surface of the steel cable.

[0014] Furthermore, the photovoltaic support cable connection structure also includes an assembly column coaxially arranged with the driving gear, and an assembly groove is provided on the assembly column.

[0015] Furthermore, each of the drivers includes a screw rotatably connected to the arc-shaped locking plate, and a knob arranged at one end of the screw away from the arc-shaped locking plate. The fixing seat is provided with threaded holes corresponding to each screw and threadedly connected to the screw at the horizontal pipe section.

[0016] By adopting the above technical solution, the staff can rotate the knob, which drives the screw to rotate, so that the arc-shaped locking piece approaches or moves away from the steel cable along the radial direction of the horizontal pipe section, thereby locking or unlocking the twisted state of the steel cable at the fixing mechanism.

[0017] Furthermore, the fastener also includes a plurality of rope buckles arranged on the conical plug along the circumference of the conical plug, each of the rope buckles is located between two adjacent dividing rods, and includes two legs assembled in the conical plug along the radial movement of the conical plug, and a head connected between two adjacent legs, the head is located in the extrusion space, and a through hole for passing the wire rope is opened on the side facing the outer wall of the conical plug.

[0018] By adopting the above technical solution, the rope buckle is used to guide each steel wire rope in the steel cable through the extrusion space to ensure that the steel wire rope can accurately enter the predetermined position during the installation process, avoiding the failure of fixation due to the deviation or entanglement of the steel wire rope. In addition, the outer side surface of the head of the rope buckle can be subjected to the extrusion force from the inner wall of the conical chamber and transmitted to the steel wire rope in the perforation, thereby firmly fixing the steel wire rope in the extrusion space, further improving the fixation reliability.

[0019] Furthermore, the fastener also includes a tightening ring arranged on the left side of the plurality of partition rods and fixedly connected to the partition rods, and the tightening ring is used to tighten the steel wire rope passing through the conical chamber through the outlet end.

[0020] By adopting the above technical solution, the tightening ring can cooperate with the part of the steel cable located at the insertion end to maintain the twisted state, so that the steel wire ropes located at the axial ends of the conical plug have a tendency to converge toward the central axis of the conical plug, which is beneficial to guide the steel wire ropes located in the extrusion space to fit closely to the outer wall of the conical plug, thereby improving the tightening effect.

[0021] Furthermore, the photovoltaic bracket cable connection structure also includes a clamp arranged on the fixed seat and located on the left side of the fastener, the clamp includes two clamp bodies that are assembled on the fixed seat opposite to each other and can move forward and backward, and the opposite sides of the two clamp bodies form a clamp groove for receiving the wire rope, and a tightening spring is arranged between each of the clamp bodies and the fixed seat, and the tightening spring is used to apply elastic force to the clamp bodies so that the two clamp bodies are close to each other, thereby closing the two clamp grooves to receive the wire rope, and the clamp groove extends outward from one end of the fastener to form a butt joint.

[0022] The beneficial effects of the photovoltaic support cable connection structure provided by the present invention are: 1. Fasteners and locking pieces are arranged on the fixing seat, and the ends of the twisted steel ropes are spread out to form multiple steel ropes, and multiple steel ropes are allowed to enter the extrusion space formed between the conical plug and the conical chamber, and the steel ropes are separated independently by the dividing rod, and the conical plug is pushed into the conical chamber by the locking piece, so that the conical plug cooperates with the conical chamber to compress and fix the steel ropes, so that each steel rope can be ensured to exist independently in the extrusion space, and be independently subjected to the extrusion force from the outer wall of the conical plug and the inner wall of the conical chamber, so that each steel rope is independently fixed, and even if a certain steel rope is broken or damaged, it will not affect the fixing effect of other steel ropes, and the overall fixing failure caused by the breakage of a single steel rope is avoided, thereby improving the reliability and safety of the entire steel rope connection mechanism. In addition, fixing each steel rope independently can also make each steel rope be subjected to uniform pressure, better transmit and disperse stress during tightening, and enhance the connection strength between the steel rope and the fixing seat.

[0023] 2. A driving gear, a fixing mechanism and a clamp are arranged on the fixing seat. The twisted state of the steel cable at the horizontal pipe section is locked by the fixing mechanism, and then the locking ring is driven to rotate by the driving gear, so that the locking ring drives the fastener to rotate. When the fastener rotates, the twisted part of the steel cable is further untied, and the tensioning machine can be connected to the clamp, and the steel cable can be tensioned by the tensioning machine, thereby realizing the tensioning adjustment function after fixation, and improving the versatility and flexibility of the steel cable connection structure of the photovoltaic bracket.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 7 As shown, and refer to Figure 1 As shown in the figure, the embodiment of the photovoltaic support cable connection structure of the present invention is used to install the end of the cable 90 on the support frame 10, including a fixing seat 20, a fastener 30, a locking member 40, a driving gear 50, a fixing mechanism 60, a clamp 70 and a protective cover 80. Among them, the fixing seat 20 is fixed on the support frame 10, and the fastener 30, the locking member 40, the driving gear 50, the fixing mechanism 60, the clamp 70 and the protective cover 80 are respectively installed on the fixing seat 20. The fastener 30 and the locking member 40 can cooperate with each other to fix the end of the cable 90 on the fixing seat 20, the driving gear 50, the fixing mechanism 60 and the clamp 70 can cooperate with each other to tension the cable 90, and the protective cover 80 is provided on the outside of the fastener 30, the locking member 40, the driving gear 50, the fixing mechanism 60 and the clamp 70 to protect the internal components and prevent accidental contact.

[0034] like Figure 2 and Figure 6 As shown, the fixing seat 20 is integrally formed with the support frame 10, and the fixing seat 20 has a conical chamber 210 that is larger on the left and smaller on the right, and a horizontal pipe section 220 located on the right side of the conical chamber 210. The left and right ends of the conical chamber 210 respectively form an exit end 212 for passing the steel wire rope 910 and an entry end 211 for passing the steel cable 90. The exit end 212 of the conical chamber 210 is connected to the outside, and the entry end 211 of the conical chamber 210 is connected to the outside through the horizontal pipe section 220. The front and rear sides of the fixing seat 20 are respectively provided with installation frames 230 extending forward and backward, and each installation frame 230 is equipped with a slider 231 that moves forward and backward.

[0035] like Figures 2 to 5 As shown, the fastener 30 is assembled on the fixing seat 20 in a left-right movable manner. The fastener 30 includes a tapered plug 310 matched with the tapered chamber 210, a plurality of partition rods 320 fixed to the left end surface of the tapered plug 310, a connecting ring 330 connected between the plurality of partition rods 320 and extending along the circumference of the tapered plug 310, a tightening ring 350 fixed to the left side of the plurality of partition rods 320 through a fixing rod 360, and a plurality of rope buckles 340 arranged on the tapered plug 310 along the circumference of the tapered plug 310.

[0036] An extrusion space is left between the outer wall of the conical plug 310 and the inner wall of the conical chamber 210. The steel cable 90 is inserted into the fixed seat 20 through the horizontal pipe section 220, and penetrates into the conical chamber 210 from the penetration end 211, and then is divided into multiple steel wire ropes 910 to pass through the extrusion space, and finally passes out of the conical chamber 210 through the penetration end 212.

[0037] The steel cable 90 in the embodiment is formed by twisting four steel wire ropes 910, and accordingly, the number of the dividing rods 320 is set to four. Each dividing rod 320 is inserted between two adjacent steel wire ropes 910, and is used to separate the steel wire ropes 910 in the steel cable 90, so as to prevent the steel wire ropes 910 from being entangled or gathered with each other, so as to ensure that each steel wire rope 910 exists independently in the extrusion space, and is independently subjected to the extrusion force from the outer wall of the tapered plug 310 and the inner wall of the tapered chamber 210, so that each steel wire rope 910 is independently fixed, and even if a certain steel wire rope 910 is broken or damaged, it will not affect the fixing effect of other steel wire ropes 910, so as to avoid the overall fixing failure caused by the breakage of a single steel wire rope 910, and improve the reliability and safety of the entire steel cable connection mechanism. In addition, independently fixing each steel wire rope 910 can also make each steel wire rope 910 be subjected to uniform pressure, better transmit and disperse stress when tightening, and enhance the connection strength between the steel wire rope 90 and the fixing seat 20.

[0038] The number of the rope buckles 340 is set to four, each rope buckle 340 is located between two adjacent partition rods 320, and includes two legs 341 that are radially movable and assembled in the tapered plug 310, and a head 342 connected between two adjacent legs 341. The leg 341 of the rope buckle 340 is designed to allow it to move radially in the tapered plug 310, providing an adjustment space, so that the position can be automatically adjusted according to the diameter and force of the wire rope 910 during the tightening process. The head 342 is located in the extrusion space, and a through hole 343 for passing the wire rope 910 is opened on the side of the outer wall of the tapered plug 310. The rope buckle 340 is used to guide each steel wire rope 910 in the steel cable 90 to pass through the extrusion space to ensure that the steel wire rope 910 can accurately enter the predetermined position during the installation process to avoid fixation failure caused by the deviation or entanglement of the steel wire rope 910. In addition, the outer side surface of the head 342 of the rope buckle 340 can be subjected to the extrusion force from the inner wall of the conical chamber 210 and transmitted to the steel wire rope 910 in the through hole 343, thereby firmly fixing the steel wire rope 910 in the extrusion space, further improving the fixation reliability.

[0039] The tightening ring 350 is used to tighten the steel wire rope 910 that passes through the conical chamber 210 through the outlet end 212. The tightening ring 350 can cooperate with the portion of the steel cable 90 that is located at the entry end 211 and is kept in a bundled state, so that the steel wire ropes 910 located at both axial ends of the conical plug 310 have a tendency to gather toward the central axis of the conical plug 310, which is conducive to guiding the steel wire rope 910 located in the extrusion space to closely fit the outer wall of the conical plug 310, thereby improving the tightening effect.

[0040] like Figure 2 and Figure 3 As shown, the locking member 40 in the embodiment adopts an elastic force locking method, and includes a locking ring 410 installed on the fixing seat 20 and located on the left side of the connecting ring 330, and a locking elastic member 420 connected between the locking ring 410 and the connecting ring 330. A plurality of locking elastic members 420 are distributed between the connecting ring 330 and the locking ring 410 along the circumference of the connecting ring 330. The locking elastic member 420 is a spring, and the locking elastic member 420 is used to apply elastic force to the connecting ring 330 to move the fastener 30 to the right, and push the tapered plug 310 into the tapered chamber 210, so that the tapered plug 310 cooperates with the tapered chamber 210 to press and fix the wire rope 910. Elastic force locking can provide continuous pressure to prevent loosening, and is quick and easy. In other embodiments, the locking member 40 can also adopt a hydraulic or pneumatic drive mechanism or other locking method that can achieve the rightward movement of the fastener 30.

[0041] like Figure 2 and Figure 6 As shown, the driving gear 50 is rotatably mounted on the fixing seat 20, the assembly column 510 is coaxially arranged with the driving gear 50, and the assembly column 510 is provided with an assembly slot 520. The assembly column 510 is used to dock with a wrench through the assembly slot 520, so that the staff can use the wrench to rotate the assembly column 510 to drive the driving gear 50 to rotate. The locking ring 410 is provided with a driven gear 411 that cooperates with the driving gear 50 and a clamping slot that is engaged with the connecting ring 330. The connecting ring 330 is guided left and right by the clamping block 331 and is assembled on the locking ring 410 in a limited manner along the circumference of the connecting ring 330, so as to rotate synchronously with the locking ring 410, thereby driving the fastener 30 to rotate. When the fastener 30 rotates, it can drive the wire rope 910 to rotate around the central axis of the tapered plug 310 through the rope buckle 340, so as to further untie the twisted part of the steel cable 90, so as to facilitate the subsequent tension adjustment.

[0042] like Figure 2 and Figure 7As shown, the fixing mechanism 60 is installed at the horizontal pipe section 220. The fixing mechanism 60 includes a plurality of arc-shaped locking pieces 610 distributed along the circumference of the horizontal pipe section 220, and a driver 620 corresponding to each arc-shaped locking piece 610 for driving each arc-shaped locking piece 610 to move radially along the horizontal pipe section 220. Each arc-shaped locking piece 610 is in an arc shape and has a pressing surface for fitting the outer surface of the steel cable 90. When the driver 620 drives the arc-shaped locking piece 610 to approach the steel cable 90 radially along the horizontal pipe section 220, the pressing surface of the arc-shaped locking piece 610 can abut the outer surface of the steel cable 90. Each driver 620 includes a screw 621 rotatably connected to the arc-shaped locking piece 610, and a knob 622 disposed at one end of the screw 621 away from the arc-shaped locking piece 610. The fixing seat 20 is provided with a threaded hole corresponding to each screw 621 and threadedly connected to the screw 621 at the horizontal pipe section 220. In this way, the staff can rotate the knob 622, which drives the screw 621 to rotate, so that the arc-shaped locking piece 610 approaches or moves away from the steel cable 90 along the radial direction of the horizontal pipe section 220, thereby locking or unlocking the twisted state of the steel cable 90 at the fixing mechanism 60.

[0043] like Figure 2 , Figure 6 and Figure 7 As shown, the clamp 70 is arranged on the fixing seat 20 and is located on the left side of the fastener 30. The clamp 70 includes two clamp bodies 710 that are opposite to each other in the front and rear, and the two clamp bodies 710 are respectively moved left and right and assembled in the slider 231. The opposite sides of the two clamp bodies 710 form a clamp groove 711 for receiving the steel wire rope 910, and the clamp groove 711 extends outward from one end away from the fastener 30 and forms a docking joint 730. A tightening spring 720 is arranged between each slider 231 and the mounting frame 230, and the tightening spring 720 is used to apply elastic force to the slider 231, so that the two sliders 231 are close to each other, and drive the two clamp bodies 710 to be close to each other, so that the two clamp grooves 711 are closed to receive the steel wire rope 910. The docking joint 730 is used to dock with the tensioning machine so that the staff can use the tensioning machine to tension the steel cable 90.

[0044] The working process of the embodiment of the photovoltaic support cable connection structure of the present invention includes the following steps: The first step is to fix the installation. Pull the fastener 30 to the left to reserve installation space for the steel cable 90. The end of the steel cable 90 is inserted into the fixing seat 20 through the horizontal pipe section 220, and penetrates into the conical chamber 210 from the insertion end 211, and then is divided into multiple steel wire ropes 910. Under the guidance of the rope threading buckle 340, it passes through the extrusion space, and then passes through the conical chamber 210 through the exit end 212. The dividing rod 320 separates the steel wire ropes 910 independently, and the steel wire rope 910 that passes through the conical chamber 210 from the exit end 212 passes through the tightening ring 350 for tightening, and then passes through the clamp groove 711 of the clamp 70. The fastener 30 is loosened, and the locking elastic member 420 applies elastic force to the connecting ring 330, so that the fastener 30 moves to the right, and the conical plug 310 is pushed into the conical chamber 210, so that the conical plug 310 cooperates with the conical chamber 210 to compress the wire rope 910, and the fixation is completed.

[0045] The second step is tension adjustment. After fixing, the staff may need to tension the steel cable 90 due to factors such as the environment, construction errors or installation deviations. The staff first locks the twisted state of the steel cable 90 at the horizontal pipe section 220 through the fixing mechanism 60, then pulls the fastener 30 to the left to leave loose space for the steel wire rope 910, and then uses a wrench to rotate the assembly column 510 to drive the driving gear 50 to rotate. The driving gear 50 drives the locking ring 410 to rotate through the driven gear 411, and the locking ring 410 drives the fastener 30 to rotate through the slot. When the fastener 30 rotates, the steel wire rope 910 is driven to rotate around the central axis of the tapered plug 310 through the rope buckle 340, and the twisted part of the steel cable 90 from the fixing mechanism 60 to the tapered plug 310 is further untied. After untying, the staff can use the tensioning machine to dock the joint 730, thereby pulling the steel cable 90, so that the untied steel wire rope 910 enters the extrusion space to tension the steel cable 90. After the tensioning is completed, the fastener 30 is loosened to fix the steel wire rope 910.

[0046] Thus, the beneficial effects of the embodiment of the photovoltaic support cable connection structure of the present invention are: 1. A fastener 30 and a locking member 40 are arranged on the fixing seat 20, and the ends of the twisted steel cable 90 are spread out to form a plurality of steel wire ropes 910, and the plurality of steel wire ropes 910 are allowed to enter the extrusion space formed between the tapered plug 310 and the tapered chamber 210, and the steel wire ropes 910 are separated independently by the partition rod 320, and the tapered plug 310 is pushed into the tapered chamber 210 by the locking member 40, so that the tapered plug 310 cooperates with the tapered chamber 210 to compress and fix the steel wire ropes 910, This ensures that each steel wire rope 910 exists independently in the extrusion space and is independently subjected to the extrusion force from the outer wall of the tapered plug 310 and the inner wall of the tapered chamber 210, so that each steel wire rope 910 is independently fixed. Even if a certain steel wire rope 910 is broken or damaged, it will not affect the fixing effect of other steel wire ropes 910, avoiding the overall fixing failure caused by the breakage of a single steel wire rope 910, thereby improving the reliability and safety of the entire steel wire rope 90 connection mechanism. In addition, by independently fixing each steel wire rope 910, each steel wire rope 910 can also be subjected to uniform pressure, better transmit and disperse stress during tightening, and enhance the connection strength between the steel wire rope 90 and the fixing seat 20.

[0047] 2. A driving gear 50, a fixing mechanism 60 and a clamp 70 are arranged on the fixing seat 20. The twisted state of the steel cable 90 at the horizontal pipe section 220 is locked by the fixing mechanism 60, and then the locking ring 410 is driven to rotate by the driving gear 50, so that the locking ring 410 drives the fastener 30 to rotate. When the fastener 30 rotates, the twisted part of the steel cable 90 is further untied, and the clamp 70 can be connected to the tensioning machine, and the steel cable 90 can be tensioned by the tensioning machine, thereby realizing the tensioning adjustment function after fixation, and improving the versatility and flexibility of the connection structure of the photovoltaic bracket steel cable 90.
