Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of transmission line tower, especially relates to a multi-loop tower line separating frame. BACKGROUND

[0002] The transmission line tower is a high-rise structure used for supporting overhead conductors, lightning conductors and other accessories in the power system, and its core function is to ensure a safe distance between the conductors and the ground and cross-over objects, and to ensure the stability and safety of power transmission.

[0003] To ensure the supply of power with different requirements, various different cables are usually arranged on the transmission line tower for transmitting power with different voltages. To avoid arc discharge and electromagnetic interference, a safe distance needs to be maintained between different loop conductors. However, the spacing between conductors of different voltage grades is different, so a separating frame needs to be arranged on the main body of the transmission line tower to support and separate different loop conductors, so that different loop conductors are fixed at predetermined spatial positions. However, due to different practical conditions and requirements, the types and quantities of different loop conductors on different transmission line towers are different, and subsequent requirements change, so the position and distribution of the conductors need to be adjusted again. The existing separating frame is usually a fixed structure connected by welding, so it is necessary to design a new separating frame for different tower requirements, which is costly. When the tower needs to be changed, the separating frame also needs to be replaced, further increasing the cost. Therefore, the existing separating frame has low versatility and high use cost. SUMMARY

[0004] Therefore, the utility model aims at providing a multi-loop tower line separating frame, which aims to solve the problem of low versatility and high use cost of the existing separating frame in the prior art.

[0005] The multi-loop tower line separating frame provided by the utility model comprises a horizontal plate, rotating arms arranged on both sides of the horizontal plate, guide rails arranged on the outer side of the rotating arms, and a driving assembly arranged on the horizontal plate, the horizontal plate and the rotating arms are both provided with wire holes at both ends, the rotating arm comprises a rotating part rotatably connected to one end of the horizontal plate, and an extension part slidably connected to the other end of the rotating part, one end of the guide rail is fixedly connected to the horizontal plate, the other end is inclinedly arranged relative to the horizontal plate and provided with a sliding groove, the outer side of the extension part is provided with a sliding block matched with the sliding groove, and the driving assembly is used for driving the rotating arm to rotate around the wire hole, so that the sliding block moves along the sliding groove, and the two extension parts are close to or away from each other.

[0006] The aforementioned multi-circuit tower line separator, by providing multiple cable routing holes, can accommodate the cable routing needs of multiple different circuits. Through the inclusion of a rotating arm, guide rails, and a drive assembly, the drive assembly can rotate the rotating part within the rotating arm, which in turn drives the extension part to rotate. The extension part is slidably connected to the rotating part and is equipped with a slider and groove adapter, allowing the extension part to extend or shorten relative to the rotating part. This makes the distance between the cable routing holes on the two extension parts, and the distance between the cable routing holes on one side of the extension part and the rotating part, adjustable. This allows the spacing between conductors of different circuits on the multi-circuit tower line separator to be adjusted as needed and then fixed. Therefore, this multi-circuit tower line separator can adjust the spacing between conductors of different lines as required, ensuring the spacing between conductors in each circuit is within a preset safety range. This eliminates the need for additional, targeted separators designed for towers with different circuit spacing requirements, greatly increasing the versatility of the multi-circuit tower line separator and avoiding the design costs of targeted separator designs. Furthermore, when the lines on the tower are changed, the multi-circuit tower line separators can be adjusted accordingly without replacing them with new ones, thus reducing the cost of changing lines on the tower. Therefore, this invention solves the problems of low versatility and high cost of existing separators in the prior art.

[0030] Please see Figures 1 to 7 The image shows a multi-circuit tower line separator according to an embodiment of the present invention, comprising a horizontal plate 10, rotating arms 20 disposed on both sides of the horizontal plate 10, guide rails 30 disposed on the outer side of the rotating arms 20, and a drive assembly 40 disposed on the horizontal plate 10, wherein:

[0031] The horizontal plate 10 and the rotating arm 20 are both provided with a wire hole 11, the rotating arm 20 comprises a rotating part 21 rotatably connected with the horizontal plate 10 and an extension part 22 slidably connected with the other end of the rotating part 21, the guide rail 30 is fixedly connected with the horizontal plate 10 at one end and is obliquely arranged relative to the horizontal plate 10 at the other end and is provided with a sliding groove 31, the extension part 22 is provided with a sliding block 221 matched with the sliding groove 31 at the outer side, and the driving assembly 40 is used for driving the rotating arm 20 to rotate around the wire hole 11 so that the sliding block 221 moves along the sliding groove 31, thereby making the two extension parts 22 close to or away from each other.

[0032] It can be understood that, by arranging a plurality of wire holes 11, the wire arrangement requirements of a plurality of different loops can be met, and by arranging the rotating arm 20, the guide rail 30 and the driving assembly 40, the rotating part 21 in the rotating arm 20 can be driven to rotate by the driving assembly 40, thereby driving the extension part 22 to rotate, and the extension part 22 is slidably connected with the rotating part 21 and is provided with a sliding block 221 matched with a sliding groove 31, so that the extension part 22 is elongated or shortened relative to the rotating part 21, thereby adjusting the distance between the wire holes 11 on the two extension parts 22 and the distance between the wire holes 11 on the extension part 22 and the rotating part 21 on one side, and thereby adjusting the distance between the wires of different loops on the multi-loop tower line separation frame according to requirements and fixing after adjustment. Thus, the multi-loop tower line separation frame can adjust the distance between the wires of different loops as required, so that the distance between the wires of different loops is within a predetermined safe range, thereby eliminating the need for additional design of a targeted separation frame for a tower with different loop spacing requirements, thereby greatly improving the universality of the multi-loop tower line separation frame and avoiding the design cost of targeted separation frame design. When the line on the tower is changed, the multi-loop tower line separation frame can also be adjusted correspondingly without the need to replace a new separation frame, thereby reducing the cost of line change on the tower. Therefore, the utility model solves the problems of low universality and high use cost of the existing separation frame in the prior art.

[0033] Specifically, the horizontal plate 10 is further provided with a reinforcing plate 50, and the two reinforcing plates 50 are symmetrically and obliquely arranged on the two sides of the horizontal plate 10 for connecting the horizontal plate 10 and the rotating part 21. In specific implementation, the two symmetrically arranged reinforcing plates 50 are added to enhance the structural strength of the horizontal plate 10 and the rotating part 21 and to share the stress at the rotating part 21, so that the rotating part 21 can be stably supported at a predetermined position when subjected to external wind.

[0034] Further, the reinforcing plate 50 includes two reinforcing rods 51, one end of which is respectively rotatably connected with the rotating part 21 and the horizontal plate 10, and the other end of which is sleeved with each other to achieve sliding connection between the two reinforcing rods 51. In specific implementation, since the position of the rotating part 21 can be adjusted according to requirements, the reinforcing plate 50 is also provided as two movably connected reinforcing rods 51, so that the length and posture of the reinforcing plate 50 can be adaptively adjusted according to the rotating part 21 to ensure the function of the reinforcing plate 50.

[0035] In addition, the horizontal plate 10 is provided with a fixing plate 60 at the bottom for fixed connection with the tower body, and two fixing plates 60 are symmetrically arranged on both sides of the middle part of the horizontal plate 10, and one side of the fixing plate 60 is connected with the horizontal plate 10 through a vertical rod 70. In specific implementation, the two symmetrically arranged fixing plates 60 enable the entire partition frame to be fixed at a predetermined position of the tower, thereby achieving the line partitioning function of the tower.

[0036] By way of example and not limitation, in some optional embodiments, the driving assembly 40 includes a driving rod 41 arranged in the middle part of the horizontal plate 10, a transmission rod 42 horizontally arranged in the inner accommodating space of the horizontal plate 10, and a driving plate 43 arranged at both ends of the rotating rod, one side of the driving rod 41 is used for connection with a power source, the other side is provided with a worm part 411, the middle part of the transmission rod 42 is provided with a worm wheel 421 matched with the worm part 411, both ends of the transmission rod 42 are provided with external threads 422, one side of the driving plate 43 is sleeved on the external threads 422 and is provided with a nut part 431 matched with the external threads 422, the other side of the driving plate 43 is provided with a rack part 432, and one end of the rotating arm 20 close to the horizontal plate 10 is provided with an external tooth part 23 matched with the rack part 432. In specific implementation, the worm part 411 is rotated to drive the worm wheel 421 to rotate, thereby driving both ends of the transmission rod 42 to rotate, the cooperation between the external threads 422 at both ends of the transmission rod 42 and the nut part 431 on the driving plate 43 enables the driving plate 43 to move forward and backward along the transmission rod 42, and the rack of the driving rod 41 cooperates with the external tooth part 23 on the rotating arm 20 to simultaneously drive the rotating arms 20 on both sides to rotate, thereby adjusting the spacing between the wire holes 11.

[0037] Specifically, the wire hole 11 is provided with a wire fixing tube 80, the wire fixing tube 80 includes a cylindrical part 81 arranged in the wire hole 11 and a conical part 82 arranged on both sides of the cylindrical part 81, and the cross-sectional area of the conical part 82 gradually increases from one side close to the cylindrical part 81 to the other side. In specific implementation, the wire fixing tube 80 is arranged to accommodate the wire, so that the wire does not rub against the wire hole 11, thereby improving the service life of the wire and the partition frame.

[0038] In some optional embodiments, the horizontal plate 10 is further provided with an auxiliary locking assembly 90 at both ends, which includes a limiting strip 91, a guide groove 92 arranged at one end of the limiting strip 91, a sleeve 93 arranged outside the limiting strip 91 and connected with the horizontal plate 10, and a locking piece 94 arranged on the sleeve 93. The outer side of the reinforcing plate 50 is provided with a guide block 52 matched with the guide groove 92. The locking piece 94 includes a connecting rod 941, a locking block 942 arranged at one side of the connecting rod 941 and located in the sleeve 93, and a pulling block 943 arranged at the other side of the connecting rod 941. The locking block 942 and the limiting strip 91 are both provided with one-way teeth 944 matched with each other. The connecting rod 941 is sleeved with a spring 95, which is located between the sleeve 93 and the locking block 942. In specific implementation, the one-way teeth 944 enable the limiting strip 91 to move in one direction only without external interference, that is, the auxiliary locking assembly 90 and the reinforcing plate 50 jointly limit the outward rotation of the rotating arm 20, thereby avoiding the spontaneous outward rotation of the rotating arm 20 under the action of external wind, so that the distance between the two wire holes 11 changes and affects use. When necessary, when the rotating arm 20 rotates outward, the pulling block 943 enables the locking block 942 to move away from the limiting strip 91 and press the spring 95. After adjustment is completed, the pulling block 943 is released and returns to the original position under the action of the spring 95, thereby achieving the locking effect. In addition, if the rotating arm 20 has a tendency to rotate inward under the action of external force, although the one-way teeth 944 cannot prevent the effect, the driving rod 41 is matched with the nut part 431 of the driving plate 43 through the external thread 422, the rack of the driving plate 43 is matched with the outer tooth part 23 of the rotating arm 20, and thus when the rotating arm 20 rotates inward under the action of external force, a force along the length direction of the driving plate 43 is applied to the outer tooth part 23, which cannot drive the nut part 431 to rotate around the external thread 422, thereby achieving the locking effect. Through reverse rotation of the driving rod 41, the driving plate 43 can be driven to move closer to each other, so that the rotating arm 20 rotates inward.

[0039] In addition, the guide rail 30 includes a vertical part 32 connected with the horizontal plate 10 at one end, two inclined parts 33 symmetrically arranged at the other end of the vertical part 32, and a sliding groove 31 connected with the inclined part 33, and the active space for the rotation of the rotating arm 20 is formed between the two inclined parts 33 on the same side. Specifically, the guide rail 30 is arranged on both sides, thereby limiting and guiding the rotating arm 20 through the two guide rails 30 to prevent the rotating arm 20 from shaking during rotation. In addition, the vertical part 32 is provided with an avoiding groove 321 for avoiding the reinforcing plate 50. Through the arrangement of the avoiding groove 321, the reinforcing plate 50 can move with the rotating arm 20 and will not interfere.

[0040] In summary, the multi-loop tower line separation frame in the above-mentioned embodiments of the utility model, through setting multiple wiring holes 11, so that the wiring needs of multiple different loops can be realized, and through setting rotating arm 20, guide rail 30 and driving assembly 40, so that rotating part 21 in rotating arm 20 can be driven to rotate by driving assembly 40, and then rotating part 21 drives extension part 22 to rotate, and extension part 22 is slidingly connected with rotating part 21, and is provided with sliding block 221 and sliding slot 31, so that extension part 22 can be lengthened or shortened relative to rotating part 21, and then the distance between wiring holes 11 on two extension parts 22 and the distance between wiring holes 11 on one side extension part 22 and rotating part 21 can be adjusted, and then the spacing between conductors of different loops on the multi-loop tower line separation frame can be adjusted according to the needs, and fixed after adjustment. So that the multi-loop tower line separation frame can adjust the spacing between conductors of different lines as needed, so that the spacing between conductors of each loop is within the preset safe range, so that the tower does not need to be additionally designed for the specific separation frame for the spacing needs of different loops, thereby greatly improving the versatility of the multi-loop tower line separation frame, and avoiding the design cost of the specific design of the separation frame. When the line on the tower is changed, the multi-loop tower line separation frame can also be adjusted correspondingly, without the need to replace a new separation frame, thereby reducing the cost of line change on the tower. Therefore, the utility model solves the problems of low versatility and high use cost of the existing separation frame in the prior art.
