Description

Technical Field

[0001] This utility model relates to the field of corner tower technology, and in particular to a dual-circuit corner tower that is easy to install. Background Technology

[0002] Double-circuit angle towers are transmission line towers used to enable the turning of double-circuit lines. They can simultaneously support conductors, lightning protection wires, and other facilities for two independent circuits. Their structure is an optimized upgrade of ordinary angle towers, typically employing a symmetrical tower head design with double-circuit crossarms arranged in layers, either vertically or horizontally, to meet the requirement of turning two lines at the same tower location (the turning angle is generally 5°–150°). The tower body must withstand the superimposed tension and lateral forces generated by the turning of the double-circuit conductors; therefore, the tower body has a larger cross-section and higher material strength, and is often equipped with reinforced main members, cross bracing, or double-sided guy wires to balance the load.

[0003] When installing side jumper insulator strings, first fix one end of the insulator string at a suitable position on the side of the power tower using hardware to ensure a firm connection; then pass the jumper through the clamp at the other end and adjust the jumper sag to the design requirements so that the insulator string is naturally vertically stressed; finally, check the electrical clearance and mechanical strength of each connection point to ensure that the jumper maintains a safe distance from the tower body and other components, and avoids the insulator string tilting or the jumper swinging excessively due to external forces such as wind and icing, thus ensuring the insulation performance and mechanical stability of the line.

[0004] When installing insulator strings, existing equipment requires workers to manually position the installation location and frequently disassemble the hardware to test whether the position is suitable, which greatly reduces the installation efficiency of the workers. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Reference Figure 1-5A convenient double-circuit corner tower includes a concrete foundation 1. A corner tower leg 2 is fixedly connected to the top of the concrete foundation 1. A corner tower body 3 is fixedly connected to the top of the corner tower leg 2. A support frame 4 is fixedly connected to the side of the corner tower body 3. An adjustment assembly is installed inside the support frame 4. The adjustment assembly includes a first connecting rod 401, a second connecting rod 402, a lead screw 403, a slider 404, a first connecting column 405, a support rod 406, a limiting groove 407, a mounting block 408, a rotating groove 409, a second connecting column 4010, and a threaded hole 4011. The first connecting rod 401 is fixedly installed inside the support frame 4, and the second connecting rod 402 is fixedly installed inside the first connecting rod 401. Located in front of connecting rod 1 401, lead screw 403 is rotatably connected between connecting rod 1 401 and connecting rod 2 402, slider 404 is threadedly connected to the outside of lead screw 403, connecting post 1 405 is symmetrically distributed and rotatably connected to the top of slider 404, support rod 406 is fixedly connected to the side surface of connecting post 1 405, limiting groove 407 is opened on the side of connecting rod 2 402 near connecting rod 1 401, mounting block 408 is symmetrically distributed and slidably connected inside limiting groove 407, rotating groove 409 is opened inside mounting block 408, connecting post 2 4010 is rotatably connected inside rotating groove 409, and threaded hole 4011 is opened on the top of mounting block 408.

[0025] The adjustment component is designed so that rotating the lead screw 403 causes the slider 404 to move outside the lead screw 403. During this rotation, the mounting block 408, via the support rod 406, limits the slider 404, and the slider 404 is threadedly connected to the lead screw 403. During this movement, the slider 404, connected to the mounting block 408 via the support rod 406, moves the mounting block 408 within the limiting groove 407. This movement of the mounting block 408 adjusts the insulator's installation position, which is then completed by bolting through the threaded hole 4011. This invention, through the adjustment component, allows the mounting block 408 to move via the rotation of the lead screw 403, facilitating the location of the installation position and effectively improving the ease of insulator installation, increasing installation efficiency, and simplifying the installation process.

[0026] Furthermore, an auxiliary groove 5 is provided on the side of the connecting rod 2 402 away from the connecting rod 1 401. An auxiliary block 6 is fixedly installed in the middle of the auxiliary groove 5. A knob 7 is rotatably connected to the side of the auxiliary block 6 away from the connecting rod 2 402. The knob 7 is fixedly connected to the lead screw 403.

[0027] The top of the connecting rod 402 is provided with a bolt groove 8. Crossarms 9 are fixedly connected to the outer side of the corner tower body 3 in a symmetrical manner. The top of the corner tower body 3 is fixedly connected with a lightning protection wire bracket 10. The bolt groove 8 makes it convenient for workers to connect the bolts and nuts with threads when installing the insulator, thereby improving the stability of the insulator installation.

[0028] Furthermore, a protective component is provided on the side of the crossarm 9 away from the corner tower body 3. The protective component includes a connecting cavity 901, a first mounting hole 902, a second mounting hole 903, a first fixing hole 904, a waterproof cover 905, and a second fixing hole 906. The connecting cavity 901 is located on the side of the crossarm 9 away from the corner tower body 3, and the first mounting hole 902 is located on the inner wall of the bottom of the connecting cavity 901.

[0029] Mounting hole 2 903 is opened on the inner walls of the left and right sides of the connecting cavity 901, fixing hole 1 904 is opened inside the connecting cavity 901, waterproof cover 905 is rotatably connected inside the connecting cavity 901, and fixing hole 2 906 is opened on the side of waterproof cover 905.

[0030] With the protective components in place, workers can first open the waterproof cover 905, then connect the corner tower components through mounting holes 902 and 903. Afterwards, the waterproof cover 905 is closed, and the components are secured with bolts through fixing holes 904 and 906, effectively improving the waterproofness of the connection cavity 901. This invention, through the protective components, effectively protects the corner tower components installed in the connection cavity 901, significantly improving both safety and practicality.

[0031] Furthermore, the mounting block 408 is adapted to the limiting slide groove 407, and the end of the support rod 406 away from the first connecting column 405 is rotatably connected to the second connecting column 4010.

[0032] In summary:

[0033] In use, this utility model first assembles the lightning protection wire bracket 10, the corner tower body 3, the crossarm 9, the corner tower leg 2, and the concrete foundation 1 using bolts.

[0034] When installing the insulator, the knob 7 can be rotated to rotate the lead screw 403. During the rotation of the lead screw 403, the mounting block 408 limits the slider 404 through the support rod 406, and the slider 404 is threadedly connected to the lead screw 403. Therefore, the slider 404 can move outside the lead screw 403. During the movement, the slider 404 is connected to the mounting block 408 through the support rod 406, which allows the mounting block 408 to move inside the limiting groove 407. During the movement of the mounting block 408, the installation position of the insulator can be adjusted. Then, the insulator can be installed by bolting through the threaded hole 4011.

[0035] Then, the waterproof cover 905 can be opened, and the components of the corner tower can be connected through mounting hole 1 902 and mounting hole 2 903. After that, the waterproof cover 905 can be closed and fixed with bolts through fixing hole 1 904 and fixing hole 2 906, thereby effectively improving the waterproofness of the connection cavity 901.
