Description

Technical Field

[0001] The utility model relates to the technical field of cable buckles, in particular to a photovoltaic flexible bracket cable buckle. Background Art

[0002] The flexible photovoltaic support system is a large-span multi-span structure. The structure uses prestressed steel wire ropes to be tensioned between the fixed points at both ends. The fixed points at both ends use a rigid structure and an outer inclined steel strand to provide support reaction force. It can achieve a large span of 10-30 m and adapt to situations such as undulating mountains and increased vegetation. It only needs to set up a foundation at a suitable location and tension the prestressed steel strands or wire ropes.

[0003] like Figure 1 As shown, when the flexible photovoltaic support is erected, a steel column foundation 1 is required to be set up below the steel columns 11 at both ends of the flexible photovoltaic support, and an inclined steel strand 121 is set outside the end steel column 11, and below the steel strand 121 is an inclined cable foundation 1211. The steel wire rope 12 system above the flexible support generates an inward horizontal tension on the top of the end steel column 11, and the horizontal tension provided by the inclined steel strand 121 at the top of the end steel column 11 can balance the horizontal tension of the steel wire rope 12. The inclined steel strand 121 has a vertical downward tension, and its vertical upward tension at the foundation position can be balanced by the pressure formed by the soil above the inclined cable foundation 1211.

[0004] In the actual process of laying out photovoltaic panels, a bracket buckle is usually fixed at the bottom of the photovoltaic module frame, and the bracket buckle is connected to the steel wire rope to complete the layout of the photovoltaic module. The bracket buckle in the existing general technology usually includes an "Ω"-shaped connector and a bolt. When in use, the "Ω"-shaped connector is clamped with the bottom of the steel wire rope, and then the bolt is passed through both ends of the "Ω"-shaped connector and connected to the bottom of the photovoltaic module frame. When assembling this connection method, the staff needs to screw multiple bolts on site to fix it, which reduces the assembly efficiency. Therefore, it is necessary to improve the relevant technology. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a photovoltaic flexible bracket buckle.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a photovoltaic flexible bracket buckle, comprising a fixed frame fixed to the bottom of the photovoltaic component frame, a first groove for cooperating with one side of a steel wire rope is arranged on one side of the fixed frame, a movable frame is hinged at the bottom of the fixed frame, a second groove for cooperating with the other side of the steel wire rope is arranged on one side of the movable frame, a first fixed block is fixed to the bottom of the fixed frame, a second fixed block is fixed to the bottom of the movable frame which is staggered with the first fixed block and fits with each other, a pin connected to the second fixed block is penetrated through the first fixed block, a first clearance groove for the second fixed block to move is arranged at the intersection of the bottom of the fixed frame and the fixed frame close to the side of the movable frame, and a second clearance groove for the first fixed block to move is arranged at the intersection of the bottom of the movable frame and the movable frame close to the side of the fixed frame.

[0007] By adopting the above technical solution, when using the photovoltaic flexible bracket buckle to connect with the wire rope, the staff only needs to rotate the movable frame around the hinge axis between it and the fixed frame to open the movable frame, and then the wire rope can be placed in the first groove. After closing the movable frame, the second groove on the movable frame cooperates with the first groove and clamps the wire rope. After the staff passes the latch through the first fixed block and connects it with the second fixed block, the latch limits the movement of the movable frame around the hinge axis, and the fixed frame cooperates with the movable frame and clamps the wire rope, which changes the traditional technology of using "Ω"-shaped connectors and bolts to connect and fix the wire rope, simplifies the fixing steps, and improves assembly efficiency. In the process of the movable frame rotating around the hinge axis between it and the fixed frame, due to the staggered arrangement of the first fixed block and the second fixed block, the first give way groove gives way to the second fixed block, and the second give way groove gives way to the first fixed block, ensuring the feasibility of the movement of the movable frame.

[0008] Furthermore, the first fixing block is penetrated by a first through hole for the pin to pass through, the second fixing block is penetrated by a second through hole for the pin to pass through at a position corresponding to the first through hole, an operating block with a diameter larger than an inner diameter of the first through hole is fixed to one end of the pin, a side wall on one side of the operating block is fitted with a position of the side wall of the first fixing block close to the first through hole, a rubber block is fixed to a position of the side wall of the pin away from the operating block, the side wall of the rubber block close to the operating block is fitted with a position of the side wall of the second fixing block close to the second through hole, the diameter of the rubber block close to the operating block end is larger than the inner diameter of the first through hole, and the diameter of the rubber block away from the operating block end is smaller than the inner diameter of the first through hole.

[0009] By adopting the above technical solution, after the bolt passes through the first through hole and the second through hole, the operating block abuts against the side wall of the first fixed block, and the rubber block abuts against the side wall of the second fixed block, thereby enhancing the stability of the connection between the bolt and the first through hole and the second through hole. The restriction on the diameter of the rubber block enables the rubber block to follow the bolt and pass through the first through hole and the second through hole in sequence.

[0010] Furthermore, the latch is arranged obliquely, and the height of the latch near one end of the operating block is greater than the height of the latch near one end of the rubber block.

[0011] By adopting the above technical solution, since the diameter of the operating block is larger than the diameter of the first through hole, the inclined setting of the pin further enhances the stability of the insertion between the pin and the first through hole and the second through hole, thereby enhancing the stability of the connection between the bracket buckle and the wire rope.

[0012] Furthermore, the latch includes a first pin and a second pin fixed to the end of the first pin, the diameter of the second pin is smaller than the diameter of the first pin, one end of the first pin is fixed to the operating block, and the rubber block is located on the second pin.

[0013] By adopting the above technical solution, the diameter of the second pin rod is smaller, which reduces the difficulty of the latch pin and the rubber block passing through the first through hole and the second through hole.

[0014] Furthermore, the diameter of the operating block at a side away from the second fixing block is greater than the diameter of the operating block at a side close to the second fixing block.

[0015] By adopting the above technical solution and limiting the diameter of the operating block, it is convenient for the staff to apply a pulling force to the operating block toward the side away from the second fixed block when removing the latch. The rubber block is deformed after being squeezed by the side wall of the second fixed block. Since the diameter of the second pin rod is small, space is provided for the deformation of the rubber block, so that it is convenient for the rubber block to withdraw from the second through hole and the first through hole in sequence until the latch is pulled out. After the latch is pulled out, the movable frame can rotate freely around the hinge axis between it and the fixed frame, so that the staff can remove the wire rope from the bracket buckle.

[0016] Furthermore, a ring magnet for magnetic attraction with the operating block is embedded in the side wall of the first fixing block around the first through hole.

[0017] By adopting the above technical solution, the operating block is made of a material that can be attracted by a magnet. Under the action of the annular magnet, the operating block is adsorbed on the first fixed block, thereby reducing the probability of the rubber block being compressed due to the external force on the latch, thereby reducing the probability of the latch falling off, and enhancing the stability of the connection between the bracket buckle and the wire rope.

[0018] Furthermore, a card strip is fixed on the side wall adjacent to the movable frame and the fixed frame near the top of the movable frame, and an elastic card block is fixed to the bottom of the photovoltaic module frame and is buckled with the bottom of the card strip. The elastic card block is L-shaped, and a chamfer is provided at the intersection between the end of the horizontal section of the elastic card block and the bottom of the elastic card block.

[0019] By adopting the above technical solution, the elastic card block is made of plastic, has good elastic properties, and has a certain structural strength. When the movable frame is closed and the card strip contacts the chamfer, the vertical part of the elastic card block is deformed until the movable frame cooperates with the fixed frame and clamps the wire rope. The elastic card block is reset and buckled with the bottom of the card strip, thereby enhancing the stability of the movable frame cooperating with the fixed frame and clamping the wire rope.

[0020] Furthermore, a fixing plate is fixed on the side wall adjacent to the fixed frame and the movable frame, a hexagon socket bolt which is gap-matched with the photovoltaic component frame is penetrated through the top of the photovoltaic component frame, the lower end of the hexagon socket bolt penetrates the fixing plate and is threadedly connected with a nut, and a receiving hole for accommodating the head of the hexagon socket bolt is provided at the top of the photovoltaic component frame.

[0021] By adopting the above technical solution, the hexagon socket bolt passes through the photovoltaic module frame and the fixing plate and is threadedly connected with the nut, which makes it easy for the staff to fix the bracket buckle to the photovoltaic module frame.

[0022] Furthermore, a first arc-shaped rubber sheet is attached to and fixed on the inner wall of the first groove, and a second arc-shaped rubber sheet is attached to and fixed on the inner wall of the second groove.

[0023] By adopting the above technical solution, the first arc-shaped rubber sheet and the second arc-shaped rubber sheet are both made of rubber material, both of which have good elastic properties. When the pin passes through the first through hole and the second through hole in sequence, the steel wire rope cooperates with the movable frame and the fixed frame to clamp the first arc-shaped rubber sheet and the second arc-shaped rubber sheet, thereby fully enhancing the stability of the connection between the bracket buckle and the steel wire rope.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. This application changes the traditional method of using "Ω"-shaped connectors and bolts to connect and fix the wire rope, simplifies the fixing steps, and improves assembly efficiency;

[0026] 2. In the present application, the restriction on the diameter of the operating block facilitates the staff to apply a pulling force to the operating block toward the side away from the second fixed block when removing the bolt. The rubber block is deformed after being squeezed by the side wall of the second fixed block. Since the diameter of the second pin is small, space is provided for the deformation of the rubber block, so that the rubber block can be withdrawn from the second through hole and the first through hole in sequence until the bolt is pulled out. After the bolt is pulled out, the movable frame can rotate freely around the hinge axis between it and the fixed frame, so that the staff can remove the wire rope from the bracket buckle;

[0027] 3. In the present application, the operating block is made of a material that can be attracted by a magnet. Under the action of the annular magnet, the operating block is adsorbed on the first fixed block, thereby reducing the probability of the rubber block being compressed due to the external force on the latch, thereby causing the latch to fall off, and enhancing the stability of the connection between the bracket buckle and the wire rope.

When using the photovoltaic flexible bracket buckle to connect with the steel wire rope 12, the staff only needs to rotate the movable frame 3 around the hinge axis between it and the fixed frame 2 to open the movable frame 3, and then the steel wire rope 12 can be placed in the first groove 21. After closing the movable frame 3, the second groove 31 on the movable frame 3 cooperates with the first groove 21 and clamps the steel wire rope 12.
