DETAILED DESCRIPTION
[0020] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0021] Please refer to Figure 1-5 An innovative and efficient transmission line pole comprises two poles 1, the two poles 1 are arranged in parallel, two cross arms 2 are arranged between the two poles 1, the two cross arms 2 are arranged in parallel up and down, the length of the lower cross arm 2 is greater than the upper cross arm 2, a ground wire insulator 3 is arranged on the top of the pole 1, a plurality of conductor insulators 4 are arranged on the cross arm 2, and a transmission line is erected inside the ground wire insulator 3 and the conductor insulator 4; through the two poles and the plurality of ground wire insulators 3 and the conductor insulator 4, efficient transmission of a double-pole double-circuit line is achieved, the power transmission demand is met, and effective insulation is achieved to improve safety performance.
[0022] Among them, a plurality of reinforcement plates 11 are provided at the bottom of the pole 1. The reinforcement plates 11 are arranged in a circular array along the pole 1. The reinforcement plates 11 are buried underground with a depth of at least 2 meters. The establishment of the reinforcement plates 11 can increase the contact area between the pole and the soil and improve the overall stability.
[0023] The back of the cross arm 2 is provided with a U-shaped rib 21 , and the cross arm 2 is provided with an assembly hole matched with the U-shaped rib 21 . The U-shaped rib 21 cooperates with a nut to fix the cross arm 2 on the wire rod 1 , thereby fixing the cross arm 2 .
[0024] In the solution of the utility model, the ground wire insulator 3 includes two vertical plates 31 on the top, and the two vertical plates 31 are connected by locking bolts 32. When installed, the line is set between the two vertical plates 31, and the top of the line is limited by the locking bolts 32; that is, the two vertical plates 31 and the locking bolts 32 above form a limiting hole, and the line is set in the hole when in use, so as to prevent the line from moving up and down or detaching from the ground wire insulator 3, thereby improving the overall stability and achieving the insulation effect.
[0025] In addition, the conductor insulator 4 includes an insulator body and a base plate 41 at the top. A semicircular depression is provided in the middle of the base plate 41, and sliding limit blocks 42 are provided on both sides of the semicircular depression. When the two sliding limit blocks 42 are in contact, the line is limited to the semicircular depression. After being limited to the semicircular depression, the line cannot be separated from the base plate, thereby meeting the requirements of stable installation.
[0026] Specifically, a slide groove 411 is provided on the surface of the bottom plate 41, and a slider 421 matching the slide groove 411 is provided at the bottom of the sliding limit block 42. A compression spring 412 is provided between the inner wall of the slide groove 411 and the slider 421. The compression spring 412 pushes the slider 421 to make the sliding limit block 42 move toward the semicircular recess. When in use, the compression springs on both sides of the semicircular recess simultaneously push the sliding limit block 42 to move toward the semicircular recess, leaving no obstruction above the blocking line and preventing the line from escaping from the semicircular recess.
[0027] In order to facilitate the rapid installation of the circuit in the semicircular recess, a slope surface 422 is provided on the surface of the sliding limit block 42, and the slope surface 422 is inclined upwards in the semicircular recess. When the circuit squeezes the slope surface 422, the sliding limit block 42 slides to both sides (outside), and the circuit can fall into the semicircular recess below after movement. After the circuit enters the semicircular recess, the compression spring pushes the sliding limit block 42 to cover the top of the circuit to prevent it from detaching.
[0028] Furthermore, the bottom surface of the sliding limit block 42 is also provided with an inner arc surface 423. When the two sliding limit blocks 42 are in contact, the two inner arc surfaces 423 and the semicircular depression form a wire passing hole 5. When in use, the line is arranged in the wire passing hole 5, and the bottom of the bottom line is limited by the semicircular depression, and the top is limited by the two inner arc surfaces 423, so that the line cannot be separated from the wire passing hole 5, thereby improving the stability of use.
[0029] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
