Description

Technical Field

[0001] This utility model relates to a device for fixing the cable ends of flexible photovoltaic support modules, belonging to the field of photovoltaic technology. Background Technology

[0002] With the booming development of the photovoltaic industry, flexible photovoltaic (PV) systems have gained increasing attention and application due to their advantages such as large span and strong adaptability, in order to adapt to complex installation scenarios. Flexible PV systems utilize steel columns at both ends and in the middle, with the module cables tensioned and fixed to these steel columns via fixing devices at both ends. After tensioning, the cable ends are fixed to the steel columns at both ends using clamp anchors. Currently, clamp anchors are commonly used to fix the cable ends. However, during long-term use, the module cables are frequently subjected to wind vibration under normal operating conditions, which can cause the clamps of the clamp anchors to loosen. This can lead to the module cables detaching from the clamp anchors, causing the cable ends to come off the steel columns at both ends of the flexible PV system. This detachment can cause local instability of the flexible system, or even the collapse of the entire flexible system, seriously affecting the safety of the flexible system structure and causing serious safety problems and economic losses. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a device for fixing the cable ends of a flexible photovoltaic support module that is simple in structure, easy to use, and securely fixed, in order to address the shortcomings of the existing technology.

[0004] To solve this technical problem, this utility model provides a device for fixing the cable ends of a flexible photovoltaic support module, including a clamp anchor, a tapered jacking pipe, a compression anchor, a support stop, and a module cable 5. The support stop has a vertical plate with a through hole through which one end of the module cable passes. The clamp anchor includes a clamp anchor cup and a tapered clamp, and is positioned on the module cable outside the support stop. One end of the tapered jacking pipe is pressed against the clamp anchor. The compression anchor is matched to the specifications of the module cable and is positioned on the module cable to wrap around it. The wrapping force of the compression anchor is greater than the maximum tensile force of the module cable 5.

[0005] The clamping anchor cup contains a conical through hole, and the outer surface of the conical clamp is the conical clamp outline. The conical through hole matches the taper of the conical clamp outline. The conical clamp is set in the conical through hole of the clamping anchor cup. The conical clamp is used to lock the component cable after tensioning the component cable. The tapered jacking pipe presses against the conical clamp of the clamping anchor.

[0006] The inner surface of the tapered clamp is provided with a tapered internal thread for engaging the component cable.

[0007] The conical clip has a split structure, with three conical clips inside one clip anchor cup.

[0008] The tapered jacking pipe is a metal round pipe with a tapered section at one end and a hollow section in the middle. The diameter of the shaft end at the contact point between the tapered section of the jacking pipe and the tapered clamp is smaller than the diameter of the contact section of the tapered clamp, so that it is tightly pressed against the tapered clamp.

[0009] The length of the tapered jacking pipe is determined based on the space required when the extrusion equipment extrudes the extrusion anchor.

[0010] The compression anchor includes a compression anchor cup and a compression spring. The compression anchor cup is a hollow anchor body with an internal threaded compression anchor cup and a tapered section at the end.

[0011] The extrusion anchor cup is made of metal, and its diameter after extrusion deformation is larger than the outer diameter of the tapered jacking pipe.

[0012] The compression spring is made of steel wire with a triangular cross-section.

[0013] The support stop is also provided with side plates, and the two side plates are arranged in parallel on the same side of the upright plate.

[0014] Beneficial Effects: This utility model overcomes the problem of component cable detachment caused by wind vibration in traditional technical solutions that use a single clamp anchor for fixing the component cable ends. It adopts a "clamp anchor + jacking pipe + compression anchor" component cable end fixing method, which effectively solves the problem of component cables detaching from the clamp anchor, thus ensuring the safety of the entire flexible photovoltaic support system. It avoids localized instability of the flexible support system, or even the collapse of the entire flexible support system, caused by component cable detachment, resulting in serious safety problems and economic losses. It has the advantages of simple design, strong practicality, and low manufacturing cost. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] like Figures 1-12 As shown, this utility model provides a device for fixing the cable ends of a flexible photovoltaic support module, including a clamp anchor 1, a tapered jacking tube 2, a compression anchor 3, a support stop 4, and a module cable 5. The support stop 4 is provided with a vertical plate and a through hole, through which one end of the module cable 5 passes. The clamp anchor 1 includes a clamp anchor cup 11 and a tapered clamp 12. The clamp anchor 1 is disposed on the module cable 5 and located outside the support stop 4. One end of the tapered jacking tube 2 is pressed against the clamp anchor 1. The compression anchor 3 is matched with the specifications of the module cable 5. The compression anchor 3 is disposed on the module cable 5 and wraps around the module cable 5. The wrapping force of the compression anchor 3 is greater than the maximum tensile force of the module cable 5.

[0019] The clamping anchor cup 11 contains a tapered through hole 111, and the outer surface of the tapered clamping piece 12 is a tapered clamping piece outline 121. The tapered through hole 111 and the tapered outline 121 of the tapered clamping piece are matched in taper. The tapered clamping piece 12 is set in the tapered through hole 111 of the clamping anchor cup 11. The tapered clamping piece 12 is used to lock the component cable 5 after tensioning the component cable 5. The tapered jacking tube 2 presses against the tapered clamping piece 12 of the clamping anchor 1.

[0020] The inner surface of the tapered clamp 12 is provided with a tapered clamp internal thread 122 for engaging the component cable 5.

[0021] The conical clip 12 has a split structure, with three conical clips 12 contained within one clip anchor cup 11.

[0022] The tapered jacking pipe 2 is a metal round pipe with a tapered section 21 at one end and a jacking pipe cavity 22 in the middle. The diameter of the shaft end where the tapered section 21 of the jacking pipe contacts the tapered clamp 12 is smaller than the diameter of the contact section of the tapered clamp 12, so that it is tightly pressed against the tapered clamp 12.

[0023] The length of the tapered jacking pipe 2 is determined according to the space required when the extrusion equipment extrudes the extrusion anchor 3.

[0024] The compression anchor 3 is made of metal and includes a compression anchor cup 31 and a compression spring 32. The compression anchor cup 31 is a hollow anchor body with an internal compression anchor cup thread 312 and a compression anchor cup tapered section 311 at the end.

[0025] The extrusion anchor cup 31 is made of metal, and its diameter after extrusion deformation is larger than the outer diameter of the tapered jacking tube 2.

[0026] The compression spring 32 is made of steel wire with a triangular cross section.

[0027] The support stop 4 is also provided with side plates, and the two side plates are arranged in parallel on the same side of the upright plate to provide support.

[0028] When using this utility model, firstly, the hydraulic tensioning equipment tensions the component cable to a certain tensile value, and then the component cable is fixed with a clamp anchor. This process is repeated to tension the component cable to the design value. After the component cable is tensioned to the design value, a tapered jacking pipe is installed, and the tapered end of the tapered jacking pipe is pressed against the clamp anchor. Then, an extrusion anchor is installed, and the extrusion anchor is pressed against the tapered jacking pipe. Finally, the extrusion equipment is used to extrude the extrusion anchor into shape.

[0029] This invention overcomes the problem of component cable detachment caused by wind vibration in traditional solutions where the cable ends are fixed using a single clamp anchor. It employs a "clamp anchor + jacking pipe + compression anchor" method for fixing the component cable ends, effectively solving the problem of component cables detaching from the clamp anchor and ensuring the safety of the entire flexible photovoltaic support system. It avoids the instability of the flexible support system, or even the collapse of the entire system, caused by component cable detachment, resulting in serious safety issues and economic losses. It has the advantages of simple design, high practicality, and low manufacturing cost.
