Technical Field

[0001] This invention relates to the field of utility pole technology, specifically to an adjustable utility pole. Background Technology

[0002] In power transmission and distribution systems, utility poles serve as crucial infrastructure supporting power lines, and their performance and function directly impact the stability and security of power supply. Traditional utility pole structures are relatively fixed, leading to numerous inconveniences during power line installation and subsequent maintenance.

[0003] The existing equipment has the following disadvantages: When installing wires, a simple binding method is usually used to fix the wires to the crossarm of the utility pole. This fixing method is not only inefficient, but also in actual application, the tension of the wires will change due to factors such as changes in ambient temperature, the wires' own expansion and contraction, and external forces. Traditional utility poles do not have the function of adjusting the tension of the wires and cannot adapt to these changes in time, which poses a hidden danger to the safe operation of the power system.

[0004] Therefore, this application proposes an adjustable utility pole to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable utility pole to solve the problem that traditional utility poles do not have the function of adjusting the tension of the wires and cannot adapt to these changes in a timely manner, thus posing a hidden danger to the safe operation of the power system.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable utility pole, comprising a pole body and a crossarm support disposed at the top of the pole body, and further comprising: The wiring unit includes a mounting component rotatably mounted on the crossarm seat and a fixing ring disposed on the side of the mounting component away from the crossarm seat for fixing the wire; An adjustment unit, mounted on the crossarm and connected to the wiring unit, is used to adjust the tightness of the wires on the wiring unit.

[0007] The mounting component includes: The connector is detachably fixed to the crossarm seat; A porcelain insulator is located on the side of the connector away from the crossarm seat; A fixing head is disposed between the connector and the porcelain bottle; The wire support is located at the lower end of the fixing head and is inclined to the side away from the crossarm seat to support the wire.

[0008] The adjustment unit includes: A support block is provided at the bottom end of the crossbeam seat; The power component is mounted on the support block; The push block is mounted on the conductor frame and connected to the power output end of the power component.

[0010] The fixing mechanism includes: The supporting base plate is vertically adjustable and can be installed inside the fixed ring. The adapter teeth are slidably disposed in the movable chamber inside the fixed ring; The extrusion plate is symmetrically arranged in the movable groove inside the fixing ring and connected to the adapter tooth, and is used to fix the wire in conjunction with the support base plate.

[0011] A telescopic rod is provided between the supporting base plate and the fixed ring, and an inflation chamber is provided between the telescopic rod and the fixed ring. The inflation chamber is connected to the mobile compartment through an air distribution chamber.

[0012] The fixing mechanism further includes: A positioning element is provided on the fixing ring for fixing the supporting base plate.

[0013] The positioning element includes: The mounting ring is disposed on the fixing ring; The movable rod passes through the mounting ring; A positioning ball is positioned on the side of the movable rod closest to the telescopic rod; An elastic element, disposed inside the mounting ring and connected to the moving rod, is used to push the positioning ball into the fixing groove opened on the telescopic rod.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-15 The present invention provides a technical solution: an adjustable utility pole, including a utility pole body 1 and a crossarm 2 disposed on the top of the utility pole body 1, and further including: a wiring unit 3, including a mounting component rotatably disposed on the crossarm 2 and a fixing ring 34 disposed on the side of the mounting component away from the crossarm 2 for fixing the wire 4; an adjustment unit 6, disposed on the crossarm 2 and connected to the wiring unit 3, for adjusting the tightness of the wire 4 on the wiring unit 3, and an insulator 5 disposed on the crossarm 2.

[0021] It should be noted that during operation, the wire 4 is inserted into the fixing ring 34 on one side of the pole body 1, and then passes through the fixing ring 34 on the other side of the pole body 1, ensuring that the wire 4 has a certain buffer section between the two fixing rings 34. After adjusting the distance between the wire 4 and the two fixing rings 34, the wire 4 is fixed by the fixing device on the fixing ring 34. When the tension of the wire 4 changes due to temperature changes, the angle between the mounting piece and the crossarm seat 2 is adjusted by the adjusting unit 6, thereby changing the tension of the wire 4. The mounting piece is detachably fixed to the crossarm seat 2, making it easier and faster to install the wiring unit 3 into the appropriate position when installing the wire 4. The fixing ring 34 and its internal fixing mechanism provide a stable and flexible way to fix the wire 4, which improves the installation efficiency compared to the traditional binding method. The adjusting unit 6 can precisely adjust the tension of the wire 4 on the wiring unit 3 according to actual needs, ensuring that the wire 4 is always in a suitable tension state, avoiding various faults caused by the wire 4 being too tight or too loose, and improving the stability and safety of power transmission.

[0022] In one embodiment, the mounting component includes: a connector 31, which is detachably fixed to the crossarm 2; a porcelain insulator 32, which is disposed on the side of the connector 31 away from the crossarm 2; a fixing head 33, which is disposed between the connector 31 and the porcelain insulator 32; and a wire support 35, which is disposed at the lower end of the fixing head 33 and is inclined to the side away from the crossarm 2 for supporting the wire 4. The wire support 35 has a wire groove 351 for installing the wire 4.

[0023] This design is for reference. Figure 1-4 The connector 31 is detachably fixed to the crossarm 2. Workers can pre-assemble the various components on the construction site and then install the connector 31 onto the crossarm 2, which shortens the installation time and improves construction efficiency. Since the connector 31 and the crossarm 2 are detachably connected, when a component is damaged or needs to be upgraded, it is not necessary to replace the entire installation; only the damaged component needs to be replaced. The wire frame 35 can guide the position of the wire 4 and adjust the placement of the wire 4. The wire groove 351 can restrict the wire 4, so that the wire 4 moves stably on the wire frame 35.

[0024] In one embodiment, the adjustment unit 6 includes: a support block 61 disposed at the bottom end of the crossbeam seat 2; a power component 62 disposed on the support block 61; and a push block 63 disposed on the conductor frame 35 and connected to the power output end of the power component 62.

[0025] This design is for reference. Figure 4The power component 62 includes, but is not limited to, electric push rods and electric telescopic rods. When it is necessary to adjust the distance between the fixed ring 34 and the crossarm seat 2, the power component 62 pushes the fixed ring 34 to swing along the connector 31 by pushing the push block 63. During power transmission, the tension of the wire 4 changes due to factors such as different seasons, different loads, and thermal expansion and contraction of the wire 4. The operator can control the power component 62 to make the push block 63 adjust the tension of the wire 4 to ensure that the wire 4 is always in the optimal tension state, thus ensuring the stability and safety of power transmission.

[0026] In one embodiment, the wiring unit 3 further includes a fixing mechanism disposed inside the fixing ring 34 for fixing the wire 4 that passes through the fixing ring 34.

[0027] This design is for reference. Figure 5 ,as well as Figure 6 The fixing mechanism is located inside the fixing ring 34 and can directly act on the inserted wire 4, clamping the wire 4 from multiple directions to ensure that the wire 4 is firmly fixed in the fixing ring 34 and is not easy to loosen or fall off, thus achieving tight fixing of the wire 4.

[0028] In one embodiment, the fixing mechanism includes: a supporting base plate 341, which is vertically and vertically disposed inside the fixing ring 34; an adapter tooth 342, which is slidably disposed in a movable compartment 3403 inside the fixing ring 34; and a pressing plate 343, which is symmetrically disposed in a movable groove 3401 opened inside the fixing ring 34 and connected to the adapter tooth 342, for cooperating with the supporting base plate 341 to fix the wire 4.

[0029] This design is for reference. Figure 8-13 The support base plate 341 is adjustable and can support the wire 4 from below. When the wire 4 is pressed against the support base plate 341, it will push the adapter teeth 342 to move inside the fixing ring 34, thereby allowing the adapter teeth 342 to adjust the pressing plate 343, so that the pressing plate 343 extends out from the inside of the movable groove 3401 and then presses and fixes the wire 4 at the upper end of the support base plate 341. The side of the pressing plate 343 connected to the wire 4 is provided with an anti-slip groove, which effectively prevents the wire 4 from loosening, shifting or rotating in the fixing ring 34, ensuring that the wire 4 can remain stably fixed in various harsh environments.

[0030] In one embodiment, a telescopic rod 3411 is provided between the support base plate 341 and the fixing ring 34, and an inflation chamber 341101 is provided between the telescopic rod 3411 and the fixing ring 34. The inflation chamber 341101 is connected to the mobile compartment 3403 through the air distribution chamber 3402.

[0031] This design is for reference. Figure 11The telescopic rod 3411 works like a syringe. It has a closed space at the bottom. When the support base plate 341 moves down, the air inside the telescopic rod 3411 will enter the air distribution chamber 3402 through the inflation chamber 341101 and then flow into the moving chamber 3403. One end of the adapter tooth 342 will be pushed by the incoming air, thereby driving the adapter tooth 342 to move, which in turn causes the extrusion plate 343 to extrude and fix the wire 4.

[0032] In one embodiment, the fixing mechanism further includes a positioning element 344, which is disposed on the fixing ring 34 and is used to fix the supporting base plate 341.

[0033] This design is for reference. Figure 10-12 After the extrusion plate 343 fixes the wire 4 on the support base plate 341, the positioning member 344 is connected to the set position on the telescopic rod 3411 to fix the telescopic rod 3411, so that the extrusion plate 343 can stably fix the wire 4 on the support base plate 341.

[0034] In one embodiment, the positioning member 344 includes: a mounting ring 3441 disposed on the fixed ring 34; a moving rod 3442 passing through the mounting ring 3441; a positioning ball 3443 disposed on the side of the moving rod 3442 near the telescopic rod 3411; and an elastic member 3444 disposed inside the mounting ring 3441 and connected to the moving rod 3442, for pushing the positioning ball 3443 into the fixing groove 341102 opened on the telescopic rod 3411. The elastic member 3444 is made of a damped spring or an elastic pad.

[0035] This design is for reference. Figure 12 ,as well as Figure 15 When the telescopic rod 3411 moves downward, the positioning ball 3443 abuts against the telescopic rod 3411. After the positioning ball 3443 contacts the fixing groove 341102 on the telescopic rod 3411, the elastic element 3444 pushes the moving rod 3442 to move closer to the telescopic rod 3411, thereby causing the positioning ball 3443 to be locked in the fixing groove 341102, thus fixing the telescopic rod 3411. At this time, the telescopic rod 3411 no longer moves downward. At this time, the pressing plate 343 clamps and fixes the wire 4 on the support base plate 341, ensuring that the wire 4 is always in a stable fixed state, improving the safety and reliability of power transmission.

[0036] In one embodiment, a gear 3431 that meshes with the adapter tooth 342 is provided on the side of the extrusion plate 343 near the adapter tooth 342, and a rotating shaft 3432 for mounting the gear 3431 is provided inside the movable groove 3401.

[0037] This design is for reference. Figure 13When the adapter tooth 342 moves inside the moving chamber 3403, it meshes with the gear 3431, causing the gear 3431 to rotate on the rotating shaft 3432. This causes the extrusion plate 343 to move closer to the wire 4, pressing and fixing the wire 4 onto the support base plate 341. The gear 3431 on the extrusion plate 343 and the adapter tooth 342 are connected by meshing. This mechanical cooperation ensures that the extrusion plate 343 can accurately approach or move away from the wire 4 according to a predetermined trajectory and position, thereby achieving precise fixing of the wire 4.

[0038] In one embodiment, an arc-shaped gripper 3433 is provided on the side of the extrusion plate 343 away from the adapter tooth 342.

[0039] This design is for reference. Figure 10 The arc-shaped gripper 3433 can better fit the outer surface of the wire 4. Compared with the flat structure, the arc-shaped gripper 3433 has a larger contact area with the wire 4, thereby increasing the friction. When fixing the wire 4, this increased friction can effectively prevent the wire 4 from sliding or loosening in the fixing ring 34, ensuring that the wire 4 is firmly fixed in the predetermined position and improving the reliability of the fixing.
