Description

Technical Field

[0001] This invention relates to the technical field of power facilities, and in particular to a lightweight insulating spacer that can firmly hold the conductor and provide strong support. Background Technology

[0002] With the development of my country's power industry, the construction of power plants and power grids has been accelerated simultaneously. During transmission line construction, various external factors such as conductor vibration due to wind and wake-induced vibration can easily cause adjacent phase conductors to touch each other and air insulation breakdown between conductors. The most effective way to solve this problem is to install insulating spacers between adjacent phase conductors, thereby ensuring sufficient insulation distance between them. For example, a high-voltage wire spacer proposed in the authorized patent application CN201720072707.2 includes a fixing ring and a disc. The fixing ring includes a buckle and a rotating shaft… The disc has an inner ring, which is aesthetically pleasing, and the ceramic structure of the fixing ring can greatly reduce the risk of conductor contact breakdown. The electromagnetic attraction between the conductors is well controlled. The bracket design is suitable for both four-split conductors and two-split and three-split conductors, making it highly adaptable. The spring design greatly improves the stability of the structure. In windy weather, the inner ring design can greatly reduce the destructive force of the wind, extend the service life of the spacer, and increase its cost-effectiveness. When fixing the conductor, the fixing ring can be rotated by the shaft, and then fixed by the buckle. However, its outer insulation - porcelain rod - has disadvantages such as heavy weight, brittleness, inconvenience to install, and high installation risk, resulting in poor practicality. Therefore, it is necessary to improve the existing insulation spacer. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a lightweight insulating spacer that can firmly grip the conductor and has strong support force. When in use, the clamping mechanism is placed on the cable, and the cable is impacted by the locking mechanism by pushing the fixing mechanism, so that the clamping mechanism closes and clamps the cable. At the same time, the locking mechanism locks the clamping mechanism. The above steps are repeated so that the clamping mechanism on another set of fixing mechanisms clamps another set of cables adjacent to it, thereby limiting the two sets of cables. This improves the convenience, safety and practicality of installing the insulating spacer.

[0004] The present invention provides a lightweight insulating spacer that can firmly grip the wire and provide strong support, comprising two sets of fixing mechanisms and a limiting mechanism. Both sets of fixing mechanisms are installed on the limiting mechanism. The fixing mechanism fixes the cable, and the limiting mechanism limits the fixing mechanism.

[0005] The fixing mechanism includes a clamping mechanism and a locking mechanism. The locking mechanism is installed on the clamping mechanism. The clamping mechanism clamps the cable, and the locking mechanism locks the clamping mechanism.

[0006] In use, place the clamping mechanism on the cable, push the fixing mechanism to make the cable hit the locking mechanism, causing the clamping mechanism to close and clamp the cable. At the same time, the locking mechanism locks the clamping mechanism. Repeat the above steps to make the clamping mechanism on another set of fixing mechanisms clamp another set of cables adjacent to it, limiting the movement of the two sets of cables, thereby improving the convenience, safety and practicality of installing the insulating spacer.

[0007] Preferably, the clamping mechanism includes a first clamping plate, a second clamping plate, and a connecting bolt. The middle of the side ends of the first and second clamping plates are rotatably mounted on the connecting bolt. By opening the top and closing the bottom of the first and second clamping plates, the cable is clamped and the cable is limited, thereby improving the practicality of the insulating spacer.

[0008] Preferably, the locking mechanism includes a pin, two sets of torsion springs, a fixed base, an L-shaped fixing clip, and a safety lock. The front ends of both the first and second clamping plates are provided with elongated through-holes extending to the rear ends, and the bottom width of the elongated through-holes is greater than the width of the remaining portions of the elongated through-holes. Multiple sets of limiting grooves are provided on the sides of both the first and second clamping plates. The bottom of the pin is provided with an elongated pre-drilled hole. The elongated pre-drilled hole of the pin and the two sets of torsion springs are both fitted onto the connecting bolt, and the pin and torsion springs are located between the first and second clamping plates. The pin is located between the two sets of torsion springs. One end of each set of torsion springs is respectively engaged in the multiple limiting grooves on the side of the first clamping plate, and the other end of each set of torsion springs is respectively engaged in the multiple slots on the side of the second clamping plate. The bottom end of the fixed base is connected to the top end of the first clamping plate. The left part of the L-shaped fixing clip is rotatably mounted on the fixed base. The safety lock is slidably mounted in the elongated through-holes of the first and second clamping plates. Before use, the first clamping plate and the second clamping plate are... The tops of the two clamping plates close, causing the bottoms of the first and second clamping plates to open into a V-shape. Simultaneously, the pin slides downward, and the L-shaped fixing clip is then placed on the second clamping plate, securing the second clamping plate with its right side. The L-shaped fixing clip covers the top of the pin, overcoming the tension of the two sets of torsion springs and limiting the position of the first and second clamping plates. Then, the first or second clamping plate is placed on the cable. By pushing the fixing mechanism, the cable hits the bottom of the pin, causing the pin to push open the L-shaped fixing clip. Through the tension of the two sets of torsion springs, the tops of the first and second clamping plates open and the bottoms close, clamping the cable. At the same time, the elongated perforations on the first and second clamping plates become parallel. Through gravity, the safety lock slides downward through the elongated perforations on the first and second clamping plates to the bottom, locking the first and second clamping plates. This improves the convenience and safety of installing the insulating spacer.

[0009] Preferably, the limiting mechanism includes a hollow resin insulating rod, with connectors provided at both the left and right ends of the hollow resin insulating rod, and a connecting handle provided at the right end of the second clamping piece. The connectors are fixedly connected to the connecting handle by bolts. The hollow resin insulating rod supports and limits the two sets of fixing mechanisms, thereby improving the practicality of the insulating spacer.

[0010] Preferably, it also includes two sets of rubber pads. The bottom of the side end of the first clip and the second clip are provided with mounting grooves. The two sets of rubber pads are respectively installed in the mounting grooves of the first clip and the second clip. After the bottom of the first clip and the second clip are closed, the cable is clamped by the two sets of rubber pads, thereby reducing the wear of the cable by the first clip and the second clip and improving the clamping firmness of the first clip and the second clip.

[0011] Preferably, its usage method includes:

[0012] Step 1: Close the top of the first and second clips, and open the bottom of the first and second clips to an "X" shape. At the same time, slide the pin downwards, and then put the L-shaped fixing clip on the second clip, so that the right part of the L-shaped fixing clip locks the second clip, and the L-shaped fixing clip covers the top of the pin, overcoming the tension of the two sets of torsion springs, and limiting the first and second clips.

[0013] Step 2: Place the first or second clip on the cable. By pushing the fixing mechanism, the cable hits the bottom of the pin, causing the pin to open the L-shaped fixing clip. Through the tension of the two sets of torsion springs, the top of the first and second clips opens and the bottom closes, clamping the cable through the two sets of rubber pads. At the same time, the long strip holes on the first and second clips become parallel, and through gravity, the safety lock slides down into the long strip holes on the first and second clips to the bottom, locking the first and second clips.

[0014] Step 3: Repeat the above steps to clamp the other set of cables on the other set of fixing mechanisms, and support the two sets of fixing mechanisms with hollow resin insulating rods to limit the movement of the two sets of cables.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. When the wire touches the pin, the first and second clamps automatically clamp the cable, eliminating the need for screws, reducing contact between workers and the cable, and improving worker safety.

[0017] 2. By using a pin to open the L-shaped fixing clip, the bottoms of the first and second clamping pieces automatically close, thereby improving the construction speed;

[0018] 3. Simple structure, easy to install and disassemble. Attached Figure Description

[0031] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. Example

[0032] like Figures 1 to 11As shown, it includes two sets of fixing mechanisms and a limiting mechanism. Both sets of fixing mechanisms are installed on the limiting mechanism. The fixing mechanism fixes the cable, and the limiting mechanism limits the fixing mechanism.

[0033] The fixing mechanism includes a clamping mechanism and a locking mechanism. The locking mechanism is installed on the clamping mechanism. The clamping mechanism clamps the cable, and the locking mechanism locks the clamping mechanism.

[0034] The clamping mechanism includes a first clamping piece 1, a second clamping piece 2, and a connecting bolt 3. The middle of the side ends of the first clamping piece 1 and the second clamping piece 2 are rotatably mounted on the connecting bolt 3.

[0035] The locking mechanism includes a pin 4, two sets of torsion springs 5, a fixing base 6, an L-shaped fixing clip 7, and a safety lock 8. The front ends of both the first clamping plate 1 and the second clamping plate 2 are provided with elongated through holes extending to the rear ends, and the bottom width of the elongated through hole is greater than the width of the rest of the through hole. The sides of both the first clamping plate 1 and the second clamping plate 2 are provided with multiple sets of limiting grooves. The bottom of the pin 4 is provided with an elongated pre-drilled hole. The elongated pre-drilled hole of the pin 4 and the two sets of torsion springs 5 ​​are all fitted onto the connecting bolt 3. Pin 4 and torsion spring 5 are both located between the first clamping plate 1 and the second clamping plate 2. Pin 4 is located between the two sets of torsion springs 5. One end of each set of torsion springs 5 ​​is respectively locked in multiple sets of limiting grooves on the side of the first clamping plate 1. The other end of each set of torsion springs 5 ​​is respectively locked in multiple sets of slots on the side of the second clamping plate 2. The bottom end of the fixing base 6 is connected to the top end of the first clamping plate 1. The left part of the L-shaped fixing clip 7 is rotatably installed on the fixing base 6. The safety lock 8 is slidably installed in the long through hole of the first clamping plate 1 and the second clamping plate 2.

[0036] The limiting mechanism includes a hollow resin insulating rod 9, with connectors 10 provided at both the left and right ends of the hollow resin insulating rod 9, and a connecting handle 11 provided at the right end of the second clamping piece 2.

[0038] Before use, close the tops of the first clip 1 and the second clip 2, and open the bottoms of the first clip 1 and the second clip 2 to a V-shape. Simultaneously, slide the pin 4 downwards. Then, place the L-shaped retaining clip 7 on the second clip 2, securing the right side of the L-shaped retaining clip 7 to the second clip 2, and cover the top of the pin 4 with the L-shaped retaining clip 7. This overcomes the tension of the two sets of torsion springs 5, limiting the position of the first clip 1 and the second clip 2. Next, place the first clip 1 or the second clip 2 on the cable. By pushing the fixing mechanism, the cable strikes the bottom of the pin 4, causing the pin 4 to push open the L-shaped retaining clip 7. The tension of the two sets of torsion springs 5 ​​then allows the first clip 1 and the second clip 2 to... The top opens and the bottom closes, clamping the cable with two sets of rubber pads 12. At the same time, the elongated perforations on the first clamping plate 1 and the second clamping plate 2 become parallel.
