Technical Field

[0001] This utility model relates to the technical field of anti-drop wire clamps for power transmission lines, specifically an anti-drop wire clamp device for power transmission lines spanning densely populated residential areas. Background Technology

[0002] A conductor failure on a power transmission line crossing a densely populated residential area can disrupt the normal operation of the area and the distribution network, causing serious public safety incidents and significant social impact and economic losses. As the main supporting structure for overhead transmission lines, towers currently use adjusting plates to connect conductors to the towers. The purpose of the adjusting plate is to adjust the length of insulator strings and conductors in overhead power lines and substations. Existing adjusting plates require workers to connect a U-shaped ring to the hardware on the conductor, then move the U-shaped ring to the desired adjustment position and fix it in place. However, because the positions of the holes on the adjusting plate are fixed, it is impossible to flexibly adjust the conductor tension. Utility Model Content

[0003] To address the problem that the fixed hole positions of existing adjustment plates prevent flexible adjustment of conductor tension, this invention provides an anti-drop wire clamp device for power transmission lines crossing densely populated residential areas. This device prevents conductors from dropping off in power transmission lines crossing densely populated residential areas and improves the flexibility of conductor tension adjustment.

The wire clamp is fixedly installed on the conductor. The connecting component includes a main adjusting plate and multiple auxiliary adjusting plates. The main adjusting plate is connected to the tower. A dovetail groove is provided at the edge of the main adjusting plate. Multiple dovetail blocks that cooperate with the dovetail groove are slidably arranged in the dovetail groove. The dovetail blocks are connected to the auxiliary adjusting plates one by one. The auxiliary adjusting plates are connected to the conductors one by one through connecting pipes. A reinforcing component is also connected between the auxiliary adjusting plates and the conductors. The reinforcing component includes at least one adjusting rod. One end of the adjusting rod is connected to the conductor through the wire clamp, and the other end of the adjusting rod is connected to the auxiliary adjusting plate.

[0005] As a further optimization of the utility model of an anti-drop wire clamp device for power transmission lines across residential areas: a connecting block is fixedly installed on the dovetail block, a first connecting unit is connected to the connecting block, a second connecting unit is connected to the auxiliary adjustment plate, and the first connecting unit and the second connecting unit are connected.

[0006] As a further optimization of the utility model of an anti-drop wire clamp device for power transmission lines across densely populated residential areas: the first connecting unit includes two first mounting plates, which are connected by a transition plate and connected to the connecting block; the second connecting unit includes two second mounting plates, which are connected by an arc-shaped plate; a connecting plate is rotatably arranged between the two second mounting plates and is rotatably connected to the two first mounting plates; a connecting bolt is passed through the auxiliary adjusting plate and is slidably arranged between the two second mounting plates.

[0007] As a further optimization of the utility model of an anti-drop wire clamp device for power transmission lines across densely populated residential areas: a blocking bolt is provided on the main adjustment plate, and the blocking bolt is located at the inlet of the dovetail groove.

[0008] As a further optimization of the utility model of a power transmission line anti-drop-off clamp device for cross-residential agglomeration areas: a stop bar is fixedly installed on the dovetail block. When the dovetail block is located in the dovetail groove, the stop bar is connected to the surface of the main adjustment plate. A fastening bolt is passed through the dovetail block, and the fastening bolt can press the dovetail block tightly against the inner wall of the dovetail groove.

[0009] As a further optimization of the utility model of an anti-drop wire clamp device for power transmission lines across densely populated residential areas: the auxiliary adjustment plate is connected to a connecting plate, and the connecting pipe is connected to the connecting plate through a second adjusting bolt.

[0010] As a further optimization of the utility model of an anti-drop wire clamp device for power transmission lines across densely populated residential areas: the adjusting rod is configured as two rods, which are respectively rotatably mounted on both sides of the clamp. The adjusting rods are connected to the secondary adjusting plate through a tension sensor. The connecting device also includes a Beidou positioning module. The tension sensor and the Beidou positioning module are electrically connected to a controller.

[0011] As a further optimization of the utility model of an anti-drop wire clamp device for power transmission lines across densely populated residential areas: the two adjusting rods are connected by a connecting shaft, and the secondary adjusting plate is connected to the connecting shaft through an adjusting assembly.

[0020] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as what is the insulator string 2, how the insulator string 2 is connected to the tower, the model of the tension sensor 26, the working principle of the Beidou positioning module, and how the Beidou positioning module and the tension sensor 26 are connected to the controller, etc.

[0021] Example 1

[0022] A type of anti-drop wire clamp device for power transmission lines spanning densely populated residential areas, such as Figures 1 to 3As shown, the device includes a connecting assembly and a clamp 5. The clamp 5 is fixedly mounted on the conductor 4. The connecting assembly includes a main adjusting plate 1 and multiple auxiliary adjusting plates 9. The main adjusting plate 1 is connected to the tower. The main adjusting plate 1 is connected to the insulator string 2 on the tower through a liner 3. The connection between the main adjusting plate 1 and the insulator string 2 on the tower is conventional prior art in this field and will not be described in detail here. To ensure the flexibility of adjusting the tension of conductor 4, a dovetail groove 22 is provided at the edge of the main adjustment plate 1. Multiple dovetail blocks 24 that cooperate with the dovetail groove 22 are slidably arranged in the dovetail groove 22. The dovetail blocks 24 are connected to the secondary adjustment plates 9 one by one. According to actual needs, the dovetail blocks 24 are slid to the appropriate position in the dovetail groove 22 and the appropriate number of secondary adjustment plates 9 are connected. The secondary adjustment plates 9 are connected to the conductor 4 one by one through the connecting pipe 10. The connecting pipe 10 is a tension clamp 5. The tension clamp 5 is conventional existing technology in this field. The specific structure, model and connection of the tension clamp 5 to the conductor 4 will not be described in detail here. Furthermore, a reinforcing component is connected between the secondary adjustment plate 9 and the conductor 4. Due to the influence of climate, especially in winter, the transmission line may be covered with ice, which increases the weight of the conductor 4, causing the sag of the conductor 4 to increase, thereby increasing the tension of the conductor 4, which may cause faults such as wire breakage. Once the conductor 4 of the transmission line is broken, it will affect the normal operation of residential areas and distribution network lines. Therefore, a reinforcing component is set. The reinforcing assembly includes at least one adjusting rod 6. One end of the adjusting rod 6 is connected to the conductor 4 via a wire clamp 5, and the other end of the adjusting rod 6 is connected to the secondary adjusting plate 9. Because the adjusting rod 6 is connected to the secondary adjusting plate 9 and the wire clamp 5, if the conductor 4 has a problem, the adjusting rod 6 can still hold the conductor 4, preventing damage caused by the conductor 4 falling off. In addition to the dovetail groove 22 on the main adjusting plate 1, a dovetail groove 22 can also be formed on the secondary adjusting plate 9, which works in conjunction with the dovetail block 24, the tension clamp 5, and the adjusting rod 6.

[0023] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0024] Example 2

[0025] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: to facilitate the connection between the dovetail block 24 and the secondary adjustment plate 9, a connecting block 25 is fixedly provided on the dovetail block 24, and the dovetail block 24 extends out of the dovetail groove 22. A first connecting unit is connected to the connecting block 25, and a second connecting unit is connected to the secondary adjustment plate 9. The first connecting unit and the second connecting unit are connected. The first connecting unit includes two first mounting plates 15, which are connected by a transition plate 14. The transition plate 14 is connected to the connecting block 25 and can be bolted to the connecting block 25. The second connecting unit includes two second mounting plates 19, which are connected by an arc-shaped plate 21. A connecting plate 17 is rotatably disposed between the two second mounting plates 19 and is rotatably connected to the two first mounting plates 15. The two first mounting plates 15 are connected by a first fixing bolt 16, which passes through the transition plate 14. The two second mounting plates 19 are connected by a second fixing bolt 18, which also passes through the transition plate 14. The first fixing bolt 16 and the second fixing bolt 18 are parallel to each other. A connecting bolt 20 is mounted on the secondary adjusting plate 9 and is slidably disposed between the two second mounting plates 19. There is a certain adjustment distance between the second fixing bolt 18 and the arc-shaped plate 21, allowing the connecting bolt 20 and the secondary adjusting plate 9 to move within this adjustment distance, making the adjustment more flexible.

[0026] Example 3

[0027] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in preventing the dovetail blocks 24 from falling off when sliding in the dovetail groove 22. A blocking bolt 23 is provided on the main adjusting plate 1, located at the inlet of the dovetail groove 22. When the dovetail blocks 24 need to slide into the dovetail groove 22, the blocking bolt 23 is unscrewed. After a suitable number of dovetail blocks 24 have entered the dovetail groove 22, the blocking bolt 23 is screwed in until it extends into the dovetail groove 22.

[0028] Example 4

[0029] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: To fix the dovetail block 24 in a suitable position, a stop bar 27 is fixedly installed on the dovetail block 24. When the dovetail block 24 is located within the dovetail groove 22, the stop bar 27 is connected to the surface of the main adjusting plate 1. A fastening bolt 13 passes through the dovetail block 24, which can press the dovetail block 24 against the inner wall of the dovetail groove 22. During the tightening of the fastening bolt 13 towards the bottom wall of the dovetail groove 22, the stop bar 27 is on the outer surface of the dovetail groove 22. Under the combined action of the fastening bolt 13 and the stop bar 27, the dovetail block 24 can be pressed firmly.

[0030] Example 5

[0031] This embodiment is an improvement on embodiment 1. Its main structure is the same as embodiment 1, but the improvement lies in that: the secondary adjusting plate 9 is connected to the connecting plate 11, and the connecting pipe 10 is connected to the connecting plate 11 via the second adjusting bolt 12. This avoids the connection being affected by insufficient length of the connecting pipe 10.

[0032] Example 6

[0033] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: To ensure smooth adjustment, two adjusting rods 6 are used, each rotatably mounted on either side of the wire clamp 5, preventing contact between the adjusting rods 6 and the wire 4 and avoiding unnecessary damage. The adjusting rods 6 are connected to the secondary adjusting plate 9 via a tension sensor 26. If the wire 4 breaks, the tension sensor 26 experiences tension. The connecting device also includes a Beidou positioning module, and the tension sensor 26 and the Beidou positioning module are electrically connected to a controller. The controller determines a wire break based on data changes from the tension sensor 26, and then uses the Beidou positioning module to determine the location of the break and triggers an alarm, prompting maintenance personnel to perform maintenance. The two adjusting rods 6 are connected by a connecting shaft, and the secondary adjusting plate 9 is connected to the connecting shaft via an adjusting assembly. The adjusting assembly includes a connecting ring 7, on which two coaxial first adjusting bolts 8 with opposite thread directions pass. One first adjusting bolt 8 is connected to the connecting shaft, and the other first adjusting bolt 8 is connected to the secondary adjusting plate 9. When it is necessary to adjust the distance between the adjusting rod 6 and the secondary adjusting plate 9, rotate the connecting ring 7 so that the two first adjusting bolts 8 move closer or further apart at the same time.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
