[0019] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0020] The invention will now be further described with reference to the accompanying drawings.

[0021] Figure 1 A schematic diagram of the structure of a telescopic pole 100 for overhead power lines according to the present invention is shown. Figure 1 As shown, according to a first aspect of the present invention, a telescopic pole 100 for overhead power lines sequentially includes a fixing component 10, a telescopic component 20, and a suspension component 30. The fixing component 10 is located at the lowest end and is fixedly connected to the ground. This provides the telescopic pole 100 with more stable support. The telescopic component 20 is located above the fixing component 10 and effectively engages with it. The suspension component 30 is located above the telescopic component 20 and is fixedly connected to its top end. The suspension component 30 effectively supports the transmission line. Furthermore, the telescopic component 20 can adjust the height of the suspension component 30 by changing its length, thereby meeting the needs of transmission lines with different height requirements.

[0022] According to the present invention, such as Figure 1 As shown, the fixing assembly 10 includes a base 11 and a tube seat 13. The base 11 is made of steel plate. Preferably, the base 11 is a circular steel plate, thereby increasing the contact area between the base 11 and the ground, which is more conducive to the fixed connection between the base 11 and the ground. The tube seat 13 extends upward from the base 11 and forms an effective engagement with the telescopic assembly 20.

[0023] In one embodiment of the present invention, such as Figure 1 As shown, the base 11 is provided with several wedges 12, and each wedge 12 is located on the same circumference. Their function will be described in detail below.

[0024] According to the present invention, such as Figure 1 As shown, the telescopic assembly 20 sequentially includes a first telescopic rod 21, a second telescopic rod 22, and a third telescopic rod 23. The diameter of the third telescopic rod 23 is smaller than the diameter of the second telescopic rod 22, allowing the third telescopic rod 23 to be nested within the second telescopic rod 22; the diameter of the second telescopic rod 22 is smaller than the diameter of the first telescopic rod 21, allowing the second telescopic rod 22 to be nested within the first telescopic rod 21.

[0025] In addition, the third telescopic rod 23 has a length longer than that of the second telescopic rod 22, so that the third telescopic rod 23 can be extended from the second telescopic rod 22; the second telescopic rod 22 has a length longer than that of the first telescopic rod 21, so that the second telescopic rod 22 can be extended from the first telescopic rod 21. In this way, different overlapping parts are formed between the first telescopic rod 21, the second telescopic rod 22 and the third telescopic rod 23 when the height of the telescopic rod 100 for stringing is adjusted. In this way, the telescopic rod 100 for stringing is effectively reinforced, so that the telescopic rod 100 for stringing itself has greater strength and good bending resistance.

[0026] According to the present application, as shown in Figure 1 The bottom end of the first telescopic rod 21 is engaged with the pipe base 13. Specifically, the pipe base 13 is provided with a plurality of first connecting holes 131 in the radial direction, and the bottom end of the first telescopic rod 21 is provided with a plurality of second connecting holes 211 in the meridian direction. The telescopic assembly 20 is effectively fixed with the fixed assembly 10 by sequentially inserting bolts into the first connecting holes 131 and the second connecting holes 211. This is well known in the art and will not be described in detail.

[0027] In one embodiment of the present application, the first telescopic rod 21, the second telescopic rod 22 and the third telescopic rod 23 are all provided with hollowed-out areas on the side walls. When the positions of the third telescopic rod 23 and the second telescopic rod 22 relative to the first telescopic rod 21 are adjusted, the hollowed-out areas can effectively reduce the contact area between adjacent telescopic rods, thereby reducing the friction between adjacent telescopic rods. In this way, the telescopic rod 100 for stringing can be more easily adjusted in height by the telescopic assembly 20 to adapt to transmission lines with different height requirements.

[0028] In one embodiment of the present application, the first telescopic rod 21, the second telescopic rod 22 and the third telescopic rod 23 are all provided with a plurality of through holes 222 of equal diameter on the side walls. When the positions of the second telescopic rod 22 and the third telescopic rod 23 relative to the first telescopic rod 21 are adjusted, the corresponding through holes 222 are all in an aligned state, and the fixing of the telescopic assembly 20 can be achieved by inserting a clamping piece through each through hole 222 into the telescopic rod 100 for stringing. In a preferred embodiment, the clamping piece is formed of a steel rod.

[0029] In one embodiment of the present application, the second telescopic rod 22 and the third telescopic rod 23 are both provided with a limiting hole 221 on the side wall, which is matched with the through hole 222. When the positions of the second telescopic rod 22 and the third telescopic rod 23 relative to the first telescopic rod 21 are adjusted, the limiting hole 221 is aligned with the through hole 222. Then, the steel bar is inserted into the through hole 222 and the limiting hole 221 in sequence until the inside of the telescopic rod 100 for stringing, so that the limiting effect of the telescopic assembly 20 is achieved.

[0030] Figure 2 Figure 3 is an assembly view of the suspension assembly 20 and the third telescopic rod 23 in the telescopic rod 100 for stringing. According to the present application, as shown in Figure 2 , the suspension assembly 30 comprises a fixed seat 40 and a support unit 50. The fixed seat 40 is connected with the top end of the third telescopic rod 23. The support unit 50 is arranged above the fixed seat 40 and is fixedly connected with the fixed seat 40, which is used to support the transmission line. By adjusting the positions of the second telescopic rod 22 and the third telescopic rod 23 relative to the first telescopic rod 21, the height of the support unit 50 is adjusted to adapt to the transmission line with different height requirements.

[0031] In one embodiment of the present application, the fixed seat 40 is configured as a hollow sleeve. The fixed seat 40 is provided with a plurality of lock pipes 41 in the circumferential direction. Each lock pipe 41 extends along a direction parallel to the longitudinal axis of the suspension assembly 30. The top end of the third telescopic rod 23 is provided with a plurality of lock channels 42 matched with the lock pipes 41. In this way, the lock pipes 41 of the fixed seat 40 and the lock channels 42 of the third telescopic rod 23 can form an effective fixed connection through the lock pin 43 inserted into the lock pipes 41 and the lock channels 42.

[0032] According to the present application, as shown in Figure 1 , the support unit 50 comprises a hanging rod 51, a floating ring 52, a hook support 53, and a support pipe 54. The hanging rod 51 extends outward from the top end of the fixed seat 40 and is fixedly connected with the fixed seat 40. The floating ring 52 is sleeved on the hanging rod 51 and can slide along the longitudinal direction of the hanging rod 51. The hook support 53 is configured as a steel pipe with an arc, which can adapt to transmission lines with different widths. The support pipe 54 is fixedly connected with the adjacent floating ring 52. By changing the length of the support pipe 54, the spacing between the adjacent hook supports 53 can be adjusted to adapt to transmission lines with different heights.

[0033] Figure 3 Figure 6 schematically shows the structure of the device 200 for fixing the telescopic rod according to the present application. As shown in Figure 3As shown, according to the second aspect of the present application, the device 200 for fixing the telescopic pole comprises a wedge needle 250 and a positioning cap 260 arranged on the wedge needle 250. The wedge needle 250 comprises an upper portion 251 and a lower portion 252. The positioning cap 260 comprises a rib sleeve 261 fixedly connected with the upper portion 251 of the wedge needle 250, and a rib cap 262 fixedly connected with the lower portion 252 of the wedge needle 250. The rib sleeve 261 is matched with the rib cap 262. In an embodiment of the present application, the wedge needle 250 can pass through the wedge seat 12 to form a fixed connection with the ground, so as to stably install the telescopic pole 100 for stringing on the ground.

[0034] In an embodiment of the present application, when the telescopic pole 100 for stringing is in the state of stringing, only the lower portion 252 of the wedge needle 250 needs to be installed on the ground through the wedge seat 12 (at this time, the rib sleeve 261 is not connected with the rib cap 262). When it is necessary to disassemble the telescopic pole 100 for stringing, the rib sleeve 261 at the upper portion 251 of the wedge needle 250 and the rib cap 262 at the lower portion 252 of the wedge needle 250 are fixedly connected through a bolt, and the wedge needle 250 is taken out from the ground by rotating the handle arranged at the upper portion 251 of the wedge needle 250. In this way, the rotation torque is effectively increased, so that the wedge needle 250 is more easily taken out from the ground through the wedge seat 12, thereby completing the disassembly work of the telescopic pole 100 for stringing.

[0035] The present application can meet the requirements of transmission lines with large height changes through the adjustment of the telescopic assembly 20, and can meet the requirements of transmission lines with small height changes through the adjustment of the suspension assembly 30. In addition, since the lengths of the first telescopic pole 21, the second telescopic pole 22 and the third telescopic pole 23 are different, each adjacent telescopic pole has an overlapping portion, so that the telescopic pole 100 for stringing has a larger thickness and stronger bending resistance.

[0036] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto. Those skilled in the art can easily make changes or modifications within the scope of the present application, and such changes or modifications shall be encompassed in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
