Description

Technical Field

[0001] The present application relates to the field of power equipment, and in particular to a power pole tower with an angle adjustment structure. Background Art

[0002] Power poles are used to support transmission lines in overhead transmission lines. They are mostly made of steel or reinforced concrete and are the main supporting structures of overhead transmission lines. They can ensure that the conductors maintain a certain safe distance from the ground and other crossing facilities under various climatic conditions, thereby ensuring the safe operation of the lines. The existing power poles usually rely on bolts to fix the brackets of the cables. These bolts are tightly fixed on the surface of the power poles to ensure the stability of the brackets. In the construction and maintenance of power facilities, it is often necessary to connect cables from different directions. This means that the angle of the bracket may need to be adjusted according to the actual situation.

[0003] However, in the existing technology, in order to make such an angle adjustment, the operator has to remove all the bolts fixing the bracket one by one; this process is not only cumbersome but also time-consuming. When installing the cable, the operator may encounter a situation where a small angle adjustment is required. The existing power poles do not have the ability to fine-tune. In this case, they usually ignore the bending of the cable in order to fix it on the bracket. In a windy environment, the bent cable may rub against the bracket under the blowing of the wind, which may cause wear on the cable surface and affect the service life of the cable.

[0025] The following is combined with Figure 1-5 This application is described in further detail.

[0026] The embodiment of the present application discloses a power pole tower with an angle adjustment structure.

[0027] Example 1

A fixing groove 2 is opened on the outer surface of the pole tower body 1, and a rotating ring 3 is embedded in the fixing groove 2. The rotating ring 3 is designed as a circular ring. The size of the rotating ring 3 is the same as that of the fixing groove 2, and the rotating ring 3 can rotate inside the fixing groove 2. The surface of the rotating ring 3 is welded and fixed to the inside of a connecting sleeve 4. A gear ring 11 is fixedly installed on the top of the outer surface of the connecting sleeve 4. The number of teeth of the gear ring 11 can be set according to needs. A connecting plate 20 is fixedly installed in the middle of the surface of the connecting sleeve 4. The connecting plate 20 is fixed to the surface of the connecting sleeve 4 by screws. The surface of the connecting plate 20 is welded and fixed to the surface of a bracket 21. The bracket 21 is designed as a triangle.

[0029] A motor 5 is fixedly installed in the inner cavity of the tower body 1, and a cover plate is fixed at the opening of the inner cavity of the tower body 1 by screws, so that the motor 5 inside the tower body 1 can be sealed. The output end of the motor 5 passes through the side wall of the body 1 and extends to the outside of the tower body 1, and is fixed to one end of the worm 6 through a coupling. A connecting plate 7 is fixedly installed on the outer surface of the tower body 1. A rotating rod 8 is rotatably connected inside the connecting plate 7. The rotating rod 8 is cylindrical in design, which is convenient for the rotating rod 8 to rotate inside the connecting plate 7. Both ends of the rotating rod 8 pass through the inside of the connecting plate 7. The top end of the rotating rod 8 is welded and fixed to the surface of the worm wheel 9, the worm wheel 9 is meshed with the worm 6, the bottom end of the rotating rod 8 is bonded and fixed to the surface of the gear 10, the gear 10 is meshed with the gear ring 11, and the number of teeth of the gear 10 can be designed according to needs.

[0030] Example 2

[0031] Reference Figure 5 A support groove 12 is provided in the inner cavity of the connecting plate 7. The support groove 12 is circular in design to facilitate the rotation of the support groove 12. A support ring 13 is connected to the inner rotation of the support groove 12. The support ring 13 is a circular ring in design. The support ring 13 is welded to the surface of the rotating rod 8, and when the rotating rod 8 rotates, the support ring 13 will rotate with it, and then the rotating rod 8 can be supported to prevent the rotating rod 8 from falling off from the inside of the connecting plate 7.

[0032] Example 3

[0033] Reference Figure 3 The inner wall of the connecting sleeve 4 is provided with a fixing groove 2 14, and the fixing groove 2 14 is circular in design. One end of the spring 15 is welded and fixed to the inner wall of the fixing groove 2 14, and the other end of the spring 15 is welded and fixed to the positioning block 16, and the positioning block 16 is semicircular in design, so that when the connecting sleeve 4 rotates, it is convenient for the positioning block 16 to be separated from the inside of the positioning groove 17. The surface of the tower body 1 is provided with a positioning groove 17, and the positioning groove 17 is circular in design. The positioning groove 17 can squeeze the spring 15, and the positioning groove 17 and the limiting groove 18 are on the same horizontal line. There are several positioning grooves 17 and limiting grooves 18, and they are evenly distributed on the surface of the tower body 1.

[0034] Example 4

[0035] Reference Figure 3A limiting groove 18 is provided on the surface of the tower body 1. Both the limiting groove 18 and the limiting groove 25 are of square design. A limiting groove 25 is provided at the bottom end of the surface of the connecting sleeve 4. The limiting groove 18 and the limiting groove 25 have the same size. When the positioning block 16 enters the interior of the positioning groove 17, the limiting groove 25 and the limiting groove 18 will overlap. The limiting groove 18 and the limiting groove 25 are internally connected with a pin 19, and the pin 19 can be pulled out from the inside of the limiting groove 18 and the limiting groove 25.

[0036] Example 5

[0037] Reference Figure 1 and Figure 2 A wire ring 22 is fixedly installed on the top of the bracket 21. The wire ring 22 is cylindrical in design. The inner wall of the wire ring 22 is elastically connected with a spring 23. The top of the spring 23 is welded and fixed to the inner wall of the wire ring 22. The bottom end of the spring 23 is welded and fixed to the top of the contact plate 24. After the cable is inserted between the wire ring 22 and the spring 23, the diameter of the cable will cause the contact plate 24 to move up, and then the spring 23 will be squeezed by the contact plate 24. The spring 23 is arc-shaped and has a rough surface, so that the spring 23 will fit on the surface of the cable and increase the friction between the wire ring 22 and the cable, thereby increasing the cable fixing effect.

[0038] Among them, the motor 5 is a prior art and will not be described in detail. The device also includes a switch, a power supply, power supply wires and a controller, etc., which are not the main technologies and will not be described in detail.

[0039] The implementation principle of the power pole tower with an angle adjustment structure in the embodiment of the present application is as follows: first, the operator sets a bolt at the bottom end of the pole tower body 1 to fix the pole tower body 1, and then the cable can be inserted between the wire ring 22 and the contact plate 24, and then the diameter of the cable will push the contact plate 24 to move, and then the contact plate 24 will squeeze the spring 23, because the spring 23 is an arc-shaped design and has a rough surface, so that the friction between the spring 23 and the cable can be increased, and then the cable is fixed inside the wire ring 22;

[0040] When it is necessary to connect cables in different directions, the latch 19 can be pulled out from the inside of the positioning groove 17 and the second limiting groove 25 to cancel the limiting of the connecting sleeve 4. Then the motor 5 is driven to rotate the worm 6. Because the worm 6 is meshed with the worm wheel 9, the worm 6 drives the worm wheel 9 to rotate. When the worm wheel 9 rotates, the support ring 13 is driven to rotate inside the support groove 12, thereby supporting the rotating rod 8. Then the worm wheel 9 drives the rotating rod 8 to rotate, and then the rotating rod 8 drives the gear 10 to rotate. Because the gear 10 is meshed with the gear ring 11, the gear 10 drives the gear ring 11 to rotate, and then the gear ring 11 drives the connecting sleeve 4 to rotate. When the connecting sleeve 4 rotates, the rotating ring 3 rotates inside the fixing groove 2.

[0041] During the rotation of the connecting sleeve 4, the positioning block 16 will be separated from the interior of the positioning groove 17. When the positioning block 16 is away from the interior of the positioning groove 17, the positioning block 16 will squeeze the spring 15, and then the connecting sleeve 4 will drive the connecting plate 20 and the bracket 21 to rotate, and then the bracket 21 will drive the wire loop 22 to rotate, and then the wire loop 22 will be rotated to a position matching the cable position, and then the positioning block 16 will be realigned with the positioning groove 17, and then the compressed spring 15 will push the positioning block 16 to re-enter the interior of the positioning groove 17, thereby completing the positioning, because the positioning groove 17 and the limiting groove 1 18 are on the same horizontal line, and then after the positioning is completed, the limiting groove 1 18 and the limiting groove 25 will be realigned, and then the latch 19 can be reinserted into the limiting groove 18 and the limiting groove 25, thereby fixing the connecting sleeve 4;

[0042] The cable can then be inserted between the wire loop 22 and the contact plate 24, thereby securing the cable.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
