Description

Technical Field

[0001] This utility model relates to the field of conductor wind deflection prevention technology, and more specifically, to a conductor wind deflection prevention device. Background Technology

[0002] In power transmission systems, overhead conductors are the key carriers for power transmission. However, conductors are highly susceptible to wind-induced deflection in natural environments. When encountering strong winds, the significant swaying of conductors not only subjects them to additional mechanical stress, accelerating wear and aging, but also shortens the safe distance between the conductors and surrounding objects. Insufficient safe distance can lead to discharge and short-circuit faults between the conductors and objects such as poles, trees, etc., seriously threatening the safe and stable operation of the power system, causing widespread power outages, and resulting in significant inconvenience to social production and people's lives.

[0003] Current conductor wind deflection prevention technologies have many shortcomings. Some wind deflection prevention devices are complex in structure, have high installation and maintenance costs, are difficult to disassemble and replace later, and require professional personnel to spend a lot of time and effort to operate, which to some extent limits their widespread application. Therefore, it is urgent to develop a conductor wind deflection prevention device that is simple in structure, easy to install, has good wind protection effect, and has a stable connection. Utility Model Content

[0007] In a preferred embodiment of this utility model, a limiting block is fixedly installed on one side of the first slide plate, and a limiting groove matching the limiting block is provided on the inner wall of the cavity. The limiting block is T-shaped.

[0008] In a preferred embodiment of this utility model, a second clamping plate is symmetrically slidably installed on the top of the support base, and a strip-shaped hole matching the second clamping plate is provided on the support base. Side plates are symmetrically fixedly installed on the bottom of the support base, and a second bidirectional threaded rod is rotatably installed between the two side plates. The bottom end of the second clamping plate passes through the strip-shaped hole and is symmetrically threaded onto the second bidirectional threaded rod. A second rotating shaft is fixedly installed at one end of the second bidirectional threaded rod, and a second turntable is fixedly installed at one end of the second rotating shaft passing through the side plate. Multiple clamping seats are fixedly installed on one side of the two second clamping plates that are relatively close to each other.

[0009] In a preferred embodiment of this utility model, the windshield is arc-shaped, and the outer side of the windshield is inclined outward.

[0010] In a preferred embodiment of this utility model, a support ring is fixedly installed on the outer side of the sleeve rod, and an annular groove matching the support ring is provided inside the support seat. The support ring is slidably connected to the inner wall of the annular groove.

[0011] In a preferred embodiment of this utility model, the bottom end of the sleeve rod slides through the bottom end of the support base and is provided with a threaded hole that matches the bolt, and the bottom end of the round rod is provided with a threaded groove that matches the bolt.

[0012] In a preferred embodiment of this utility model, insert plates are symmetrically arranged on the outer side of the round rod, and sliding grooves matching the insert plates are symmetrically arranged on the inner wall of the sleeve rod.

[0013] The beneficial effects of this utility model are:

[0014] Effective wind deflection prevention: The device is equipped with an arc-shaped windshield that slopes outward. Its unique shape design can better change the direction of airflow, disperse the force of wind on the conductor, reduce the wind load on the conductor, thereby effectively suppressing the wind deflection of the conductor, reducing the risk of line faults caused by wind deflection, and ensuring the stability of power transmission.

[0015] Secure Installation: The clamping assembly inside the base, by rotating the first bidirectional threaded rod, moves the first sliding plate and the first clamping plate, firmly fixing the device to the support structure such as the tower. The arc-shaped design of the first clamping plate and the inner wall insertion rod can better fit the surface of the tower, enhancing the fixing effect; at the same time, the second clamping plate on the support base, together with the second bidirectional threaded rod, can provide secondary clamping and fixing of the conductor. Multiple clamping bases further increase the contact area with the conductor, preventing the conductor from shaking during operation and ensuring a stable connection between the entire device and the conductor.

[0016] Stable structure: The threaded hole at the bottom of the sleeve rod and the threaded groove at the bottom of the round rod are bolted together, ensuring the firmness of the connection between the two; the insert plate on the outside of the round rod and the sliding groove on the inner wall of the sleeve rod cooperate with each other, which not only enhances the stability of the connection, but also prevents the round rod from rotating inside the sleeve rod, ensuring the structural stability of the entire anti-wind deflection device during use.

[0017] Buffer protection: The springs, circular plates and top rods on both sides of the inner wall of the groove form a buffer structure. When the windshield is impacted by wind and shakes, the top rod remains in contact with the vertical plate under the action of the spring, which plays a role in buffering and restoring the windshield, reducing the damage to the device caused by the instantaneous change of wind force, and extending the service life of the device.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please see Figures 1-7 This utility model provides a technical solution: a wire anti-wind deflection device, including a base 110, a clamping assembly installed inside the base 110, a diagonal rod 111 fixedly installed on one side of the base 110, a support seat 120 fixedly installed at the top of the diagonal rod 111, grooves 121 symmetrically arranged at the top of the support seat 120, a sleeve rod 122 rotatably installed at the bottom of the inner wall of the groove 121, a round rod 123 slidably sleeved at the top of the sleeve rod 122 and fixedly connected by bolts 1201, a wind shield 124 fixedly installed at the top of the round rod 123, a vertical plate 125 symmetrically fixedly installed at the bottom of the wind shield 124, springs 126 symmetrically fixedly installed on both sides of the inner wall of the groove 121, a round plate 127 fixedly installed at one end of the spring 126, a top rod 128 fixedly installed on the round plate 127, one end of the top rod 128 is arc-shaped and fits against one side of the vertical plate 125, and a round groove matching the top rod 128 is provided on the inner wall of the groove 121.

[0029] Please see Figure 2The clamping assembly includes a first clamping plate 1103. A curved groove is provided on one side of the base 110, and a cavity is provided on the inner wall of the curved groove. A first bidirectional threaded rod 1101 is rotatably installed between the two sides of the inner wall of the cavity. First sliding plates 1102 are symmetrically threaded onto the first bidirectional threaded rod 1101. The first clamping plate 1103 is fixedly installed on one side of the two first sliding plates 1102 that are relatively close to each other. A first rotating shaft is fixedly installed at one end of the first bidirectional threaded rod 1101. One end of the first rotating shaft passes through the base 110 and is fixedly installed on a first turntable 1104. A groove is provided on one side of the first turntable 1104, and a straight plate is installed on the inner wall of the groove. The first clamping plate 1103 is curved, and a plug rod is fixedly installed at the center of the inner wall of the first clamping plate 1103. This structure allows for convenient adjustment of the spacing of the first clamping plates 1103 by rotating the first turntable 1104, adapting to towers of different sizes, enhancing the compatibility of the device with the tower connection, ensuring the device is firmly installed, and preventing loosening of the device due to poor fit, which would affect the wind deflection prevention effect.

[0030] In some specific implementation schemes, a limiting block 1105 is fixedly installed on one side of the first sliding plate 1102, and a limiting groove matching the limiting block 1105 is provided on the inner wall of the cavity. The limiting block 1105 is T-shaped to ensure that the first clamping plate 1103 moves smoothly, maintains stable clamping of the tower, and improves the fixing effect.

[0031] Please see Figures 3-7 The support base 120 has a second clamping plate 130 symmetrically slidably mounted on its top end. The support base 120 has a strip hole that matches the second clamping plate 130. The support base 120 has a side plate 131 symmetrically fixedly mounted on its bottom end. The two side plates 131 are rotatably mounted with a second bidirectional threaded rod 132. The bottom end of the second clamping plate 130 passes through the strip hole and is symmetrically threaded onto the second bidirectional threaded rod 132. One end of the second bidirectional threaded rod 132 is fixedly mounted with a second rotating shaft. One end of the second rotating shaft passes through the side plate 131 and is fixedly mounted with a second turntable. The two second clamping plates 130 are fixedly mounted with multiple clamping seats on one side that is relatively close to each other. The windshield 124 is arc-shaped and the outer side of the windshield 124 is inclined outward.

[0032] In some specific implementations, a support ring 1221 is fixedly installed on the outer side of the sleeve rod 122, and an annular groove matching the support ring 1221 is provided inside the support base 120. The support ring 1221 is slidably connected to the inner wall of the annular groove. This provides stable support and guidance for the sleeve rod 122, making the rotation of the sleeve rod 122 smoother and ensuring that the windshield 124 remains stable when adjusting its angle according to changes in wind direction, thereby improving the flexibility and stability of the wind deflection device in response to different wind directions.

[0033] In some specific implementations, the bottom end of the sleeve rod 122 slides through the bottom end of the support base 120 and is provided with a threaded hole that matches the bolt 1201. The bottom end of the round rod 123 is provided with a threaded groove that matches the bolt 1201. The connection of the sleeve rod 122 and the round rod 123 through the bolt 1201 makes the connection between the sleeve rod 122 and the round rod 123 tighter and more secure. It is convenient to adjust the height of the windshield 124 according to actual needs and then fix it reliably, ensuring the stability of the device structure and preventing the windproof performance from being affected by loose connection during use. The outer side of the round rod 123 is symmetrically provided with insert plates, and the inner wall of the sleeve rod 122 is symmetrically provided with sliding grooves that match the insert plates, which further improves the stability of the connection between the sleeve rod 122 and the round rod 123.

[0034] Working principle: First, the device is installed on the pole using the clamping assembly inside the base 110, and matching holes for the insertion rod are drilled on the pole. Rotating the first turntable 1104 drives the first rotating shaft and the first bidirectional threaded rod 1101 to rotate. Under the action of the threads, the two first sliding plates 1102 move relative to each other, clamping the first clamping plate 1103 onto the pole. The arc-shaped design of the first clamping plate 1103 and the insertion rod on its inner wall enhance the fit with the pole surface, improving the fixing effect. Then, the wire is placed on the support base 120, and rotating the second turntable drives the second rotating shaft to rotate, causing the second bidirectional threaded rod 132 to rotate. The second clamping plate 130 slides relative to each other within the slotted hole, clamping the wire. The multiple clamping seats on the second clamping plate 130 increase the contact area with the wire, preventing the wire from shaking.

[0035] Buffer Protection: When wind blows towards the conductor, the arc-shaped windshield 124, with its outer side tilted outwards, changes the direction of the airflow, dispersing the force of the wind on the conductor, reducing the wind load on the conductor, and suppressing the wind deflection amplitude of the conductor. Under the action of wind force, the windshield 124 may sway. At this time, the buffer structure composed of springs 126, circular plates 127, and push rods 128 on both sides of the inner wall of the groove 121 comes into play. When the windshield 124 sways, the vertical plate 125 presses against the push rods 128, and the push rods 128 press against the springs 126. The springs 126 contract and deform to absorb part of the impact force. When the wind force weakens, the springs 126 return to their original deformation, pushing the push rods 128 so that the push rods 128 are always in contact with the vertical plate 125, restoring the windshield 124 to its original position, reducing the damage to the device caused by sudden changes in wind force, and extending the service life of the device.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
