Description

Technical Field

[0001] This utility model relates to the field of power line equipment technology, and in particular to a spiral adjustment plate for power lines. Background Technology

[0002] In the installation and maintenance of power lines, the tension and position adjustment of the lines are crucial. Appropriate line tension ensures stable operation, preventing line breakage due to excessive tension or slackness and swaying due to insufficient tension, thus affecting the safety and stability of power transmission. Currently, most existing power line adjustment devices are complex in structure and cumbersome to operate, requiring significant manpower and time. Furthermore, some devices have low adjustment accuracy, failing to meet the high-precision installation and maintenance requirements of modern power lines. In addition, existing adjustment devices are prone to component wear and loosening during long-term use, leading to decreased adjustment effectiveness, increased maintenance costs, and safety hazards. Therefore, there is an urgent need for a power line adjustment device that is simple in structure, easy to operate, highly accurate, and stable.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: fixed-length wires may not be able to be properly connected due to being too long or too short. If they are too long, the wires will become redundant and pile up, increasing the risk of mechanical wear or causing the wires to sag due to gravity, resulting in poor contact. If the wires are too short, forcibly stretching them will subject them to abnormal tension, which may cause the internal conductors to break, the insulation layer to be damaged, or even cause the terminal connections to fall off. Therefore, a spiral adjustment plate for power lines is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies where fixed-length wires may not be able to connect properly due to being too long or too short. If the wires are too long, they may become redundant and accumulate, increasing the risk of mechanical wear or causing the wires to sag due to gravity, resulting in loosening and poor contact. If the wires are too short, forcibly stretching them may subject them to abnormal tension, potentially causing internal conductor breakage, insulation damage, or even detachment of the terminal connection. Therefore, a spiral adjustment plate for power lines is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spiral adjusting plate for power lines, comprising a connecting frame, an adjusting device on the surface of the connecting frame, the adjusting device comprising a U-shaped frame, the U-shaped frame being rotatably connected to the surface of the connecting frame, a round rod slidably inserted into the inner surface of the U-shaped frame, a shaped plate rotatably connected to the arc surface of the round rod, a fixing rod rotatably connected to the inner surface of the shaped plate, adjusting frames fixedly connected to both ends of the fixing rod, a threaded rod threadedly inserted into the inner surface of the connecting frame, two elliptical frames rotatably connected to the arc surface of the threaded rod, a nut rotatably connected to the arc surface of the threaded rod, screws threadedly inserted into the inner surfaces of the two elliptical frames, a screw tube rotatably connected to the arc surface of the screw, a setting plate rotatably connected to the arc surface of the screw, and wires installed on the inner surface of the adjusting frame.

[0006] The effect achieved by the above components is as follows: by setting the adjustment device, the length of the wire can be adjusted, which avoids the possibility that a fixed length of wire may not be able to be properly connected due to being too long or too short. If the wire is too long, it will cause redundant accumulation of wire, increasing the risk of mechanical wear or causing the wire to sag due to gravity, resulting in poor contact. If the wire is too short, forcibly stretching the wire will subject it to abnormal tension, which may cause the internal conductor to break, the insulation layer to be damaged, or even cause the terminal connection to fall off.

[0007] Preferably, the arc surface of the fixing rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the inner surface of the adjusting frame and one side of the irregular plate, respectively.

[0008] The effect achieved by the above components is that by setting a torsion spring, the position of the irregular plate can be rotated, making it easier for workers to install the round rod.

[0009] Preferably, a rotating rod is rotatably connected to the inner surface of the adjusting frame, and a gear is fixedly connected to the arc surface of the rotating rod.

[0010] The effect achieved by the above components is to spiral the wires to the arc surface of the rotating rod and adjust the length of the wires.

[0011] Preferably, a drive rod is fixedly connected to the surface of the adjustment frame, a blocking rod is fixedly connected to the surface of the adjustment frame, and the arc surface of the drive rod is rotatably connected to the blocking frame.

[0012] The effect achieved by the above components is that the blocking bracket limits the position of the gear, further enhancing the stability of the spirally wound wire.

[0013] Preferably, one end of the round rod is provided with a limiting device, the limiting device including a U-shaped tube, the U-shaped tube being fixedly connected to one end of the round rod, two fixing brackets being fixedly connected to the inner surface of the U-shaped tube, a limiting tube being slidably connected to the arc surface of the U-shaped tube, a sliding rod being slidably inserted into the inner surface of the fixing bracket, and a round block being fixedly connected to one end of the sliding rod.

[0014] The effect achieved by the above-mentioned components is as follows: by setting the limiting device, the round rod is limited, which prevents the round rod from suddenly sliding out of the inner surface of the U-shaped frame and causing damage to the electrical equipment. If the round rod falls off, it will pull the wires, causing the terminal connection to loosen, break or fall off, resulting in circuit interruption or poor contact. If it is a high-voltage line, an electric arc may be generated at the moment of falling off, burning the insulation layer of the wire or the equipment interface, causing permanent electrical damage.

[0015] Preferably, a handle is fixedly connected to the arc surface of the circular block, and the circular block is fixedly connected to the inner surface of the U-shaped tube.

[0016] The effect achieved by the above-mentioned components is that by setting a handle, it is convenient for workers to adjust the circular block left and right, thereby adjusting the position of the sliding rod.

[0017] Preferably, a spring is fixedly connected to one side of the two circular blocks that are close to each other, and one end of the limiting tube abuts against the arc surface of the sliding rod.

[0018] The effect achieved by the above components is that, by setting springs, the two sliding rods are automatically slid out of the inner surface of the U-shaped tube to limit the position of the limiting tube.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting an adjustment device, the effect of adjusting the length of the wire is achieved, which avoids the possibility that a fixed length of wire may not be able to be properly connected due to being too long or too short. If the wire is too long, it will cause redundant accumulation of wire, increasing the risk of mechanical wear or causing the wire to sag due to gravity, resulting in poor contact. If the wire is too short, forcibly stretching the wire will subject it to abnormal tension, which may cause the internal conductor to break, the insulation layer to be damaged, or even cause the terminal connection to fall off.

[0021] 2. In this utility model, by setting a limiting device, the round rod is limited, which avoids the round rod from suddenly sliding out of the inner surface of the U-shaped frame and causing damage to the power equipment. If the round rod falls off, it will pull the wire, causing the terminal connection to loosen, break or fall off, resulting in circuit interruption or poor contact. If it is a high-voltage line, an electric arc may be generated at the moment of falling off, burning the insulation layer of the wire or the equipment interface, causing permanent electrical damage.

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a spiral adjustment plate for power lines, including a connecting frame 1. The surface of the connecting frame 1 is provided with an adjustment device 3. By setting the adjustment device 3, the length of the wire 2 can be adjusted, avoiding the possibility that a fixed-length wire 2 may not be able to connect properly due to being too long or too short. If it is too long, the wire 2 will be redundant and piled up, increasing the risk of mechanical wear or causing the line to loosen and have poor contact due to gravity. If it is too short, forcibly stretching the wire 2 will subject it to abnormal tension, which may cause the internal conductor to break, the insulation layer to be damaged, or even cause the terminal connection to fall off. One end of the round rod 302 is provided with a limiting device 4. By setting the limiting device 4, the round rod 302 is limited, preventing the round rod 302 from suddenly sliding out of the inner surface of the U-shaped frame 301 and causing damage to the power equipment. If the round rod 302 falls off, it will pull the wire 2, causing the terminal connection to loosen, break or fall off, causing circuit interruption or poor contact. If it is a high-voltage line, an electric arc may be generated at the moment of falling off, burning the wire insulation layer or equipment interface, causing permanent electrical damage.

[0029] The specific settings and functions of the adjustment device 3 and the limit device 4 will be explained in detail below.

[0030] Reference Figure 2 , Figure 3 and Figure 4 As shown in this embodiment: the adjusting device 3 includes a U-shaped frame 301, which is rotatably connected to the surface of the connecting frame 1. A round rod 302 is slidably inserted into the inner surface of the U-shaped frame 301. A shaped plate 303 is rotatably connected to the arc surface of the round rod 302. A fixing rod 304 is rotatably connected to the inner surface of the shaped plate 303. Adjusting frames 305 are fixedly connected to both ends of the fixing rod 304. A threaded rod 306 is threaded into the inner surface of the connecting frame 1. Two elliptical frames 307 are rotatably connected to the arc surface of the threaded rod 306. A nut 308 is rotatably connected to the arc surface of the threaded rod 306. A screw 309 is threaded into the inner surface of the two elliptical frames 307. A screw tube 310 is rotatably connected to the arc surface of the screw 309. A setting plate 311 is rotatably connected to the arc surface of the screw 309. A wire 2 is installed on the inner surface of the adjusting frame 305. Two torsion springs 312 are fitted onto the arc surface of the fixing rod 304. The two ends of the torsion springs 312 are fixedly connected to the inner surface of the adjusting frame 305 and one side of the shaped plate 303, respectively. By setting the torsion springs 312, the position of the shaped plate 303 can be rotated, facilitating the installation of the round rod 302. A rotating rod 313 is rotatably connected to the inner surface of the adjusting frame 305, and a gear 314 is fixedly connected to the arc surface of the rotating rod 313. The wire 2 is spirally collected onto the arc surface of the rotating rod 313, allowing for adjustment of the wire 2's length. A driving rod 315 and a blocking rod 316 are fixedly connected to the surface of the adjusting frame 305, and a blocking frame 317 is rotatably connected to the arc surface of the driving rod 315. The blocking frame 317 limits the position of the gear 314, further enhancing the stability of the spirally wound wire 2.

[0031] Reference Figure 5 As shown, specifically, the limiting device 4 includes a U-shaped tube 41, which is fixedly connected to one end of a round rod 302. Two fixing brackets 43 are fixedly connected to the inner surface of the U-shaped tube 41. A limiting tube 42 is slidably connected to the arc surface of the U-shaped tube 41. A sliding rod 44 is slidably inserted into the inner surface of the fixing bracket 43, and a round block 45 is fixedly connected to one end of the sliding rod 44. A handle 46 is fixedly connected to the arc surface of the round block 45, and the round block 45 is fixedly connected to the inner surface of the U-shaped tube 41. By setting the handle 46, it is convenient for the operator to adjust the round block 45 left and right, thereby adjusting the position of the sliding rod 44. A spring 47 is fixedly connected to the side of the two round blocks 45 that are close to each other, and one end of the limiting tube 42 abuts against the arc surface of the sliding rod 44. By setting the spring 47, the two sliding rods 44 are automatically slid out of the inner surface of the U-shaped tube 41, limiting the limiting tube 42.

[0032] Working principle: When the operator needs to adjust the length of the connecting structure using the adjusting device 3, firstly, the surface of the U-shaped frame 301 is moved around the inner surface of the connecting frame 1. Then, the round rod 302 is inserted sequentially into the U-shaped frame 301, the irregular plate 303, and the inner surface of the U-shaped frame 301. The threaded rod 306 on the other side of the connecting frame 1 is inserted sequentially into the inner surfaces of the elliptical frame 307, the connecting frame 1, and the elliptical frame 307. The nut 308 is rotated on the arc surface of the threaded rod 306. Subsequently, the screw 309 is inserted sequentially into the inner surfaces of the elliptical frame 307, the setting plate 311, and the elliptical frame 307. The screw tube 310 is rotated on the arc surface of the screw 309. When it is necessary to change the round hole of another irregular plate 303, the round rod 302 is... Sequentially detaching from the U-shaped frame 301, the irregular plate 303, and the inner surface of the U-shaped frame 301, due to the torque of the torsion spring 312, the irregular plate 303 rotates on the arc surface of the fixed rod 304. Using a suitable round hole on the irregular plate 303, the round rod 302 is sequentially inserted into the inner surface of the U-shaped frame 301, the irregular plate 303, and the U-shaped frame 301. When it is necessary to adjust the length of the wire 2, rotate the rotating rod 313, and the wire 2 winds around the arc surface of the rotating rod 313. The gear 314 rotates on the arc surface of the rotating rod 313. When it rotates to the appropriate position, the blocking frame 317 rotates on the arc surface of the driving rod 315, so that one side of the blocking frame 317 abuts against the gear 314, and the other side abuts against the blocking rod 316, thus limiting the gear 314.

[0033] When the staff needs to use the limiting device 4 to limit the U-shaped frame 301, first slide the limiting tube 42 on the arc surface of the U-shaped tube 41. When the limiting tube 42 abuts against one side of the sliding rod 44, continue to push, and the sliding rod 44 slides on the inner surface of the fixed frame 43. Pull the handle 46 to drive the sliding rod 44 to slide on the inner surface of the fixed frame 43. The round block 45 compresses the spring 47. When the limiting tube 42 reaches the other side of the sliding rod 44, release the handle 46. The spring 47 rebounds, the round block 45 rebounds, and the sliding rod 44 slides on the inner surface of the fixed frame 43. The sliding rod 44 limits the position of the limiting tube 42.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
