Description

Technical Field

[0001] This utility model relates to the technical field of power pipe connection structure, specifically to a high-voltage power pipe connection structure for power transmission. Background Technology

[0002] Power conduits are products made by hot-dip plastic coating of PE (modified polyethylene) or internal and external coating of epoxy resin. They have excellent corrosion resistance, and the coating itself also has good electrical insulation, preventing electrolytic corrosion. They have low water absorption, high mechanical strength, and a low coefficient of friction, enabling long-term use. In daily life, high-voltage power conduits are typically installed on the outside of high-voltage lines and buried underground for power transmission during the construction of high-voltage power lines.

[0003] During the laying of high-voltage power pipes, it is usually necessary to support and align two power pipes before installation. However, the ground level of the foundation pit has a difference in height, and the general support devices are not flexible enough to adjust power pipes of different heights, which makes it inconvenient for workers to install them. Utility Model Content

[0007] Power pipe one and power pipe two;

[0008] An adjustment mechanism is installed on the surfaces of power pipe one and power pipe two for adjusting the height of power pipe one and power pipe two;

[0009] A fixing mechanism is installed on the surfaces of power pipe one and power pipe two for fixing power pipe one and power pipe two together.

[0010] Furthermore, the adjustment mechanism includes a support frame, which is movably installed with power pipe one and power pipe two. Two fixing plates are fixedly connected to the upper surface of the support frame. A lead screw is threadedly connected to the inner wall of the fixing plate.

[0011] The above technical solution allows for adjustment of the height of the power pipe, facilitating the installation between two power pipes.

[0012] Furthermore, a rubber pad is fixedly connected to the inner wall of the support frame.

[0014] Furthermore, a fixing rod is fixedly connected to the surface of the arc plate, and the fixing rod is slidably connected to the fixing plate.

[0015] The above technical solution can restrict the direction of movement of the arc plate.

[0016] Furthermore, the surface of the base plate is fixedly connected with several spikes.

[0017] The above technical solution ensures that the base plate is not easily moved when placed on the soil surface.

[0018] Furthermore, the fixing mechanism includes a connecting pipe, which is fixedly installed at one end of the power pipe one. Two protrusions are fixedly connected to the arc surface of the connecting pipe. A square groove is formed on the inner wall of the protrusion. Several springs one are fixedly connected to the inner wall of the square groove. A snap-fit ​​block is fixedly connected to one end of the spring one. A sleeve is fixedly installed at one end of the power pipe two. Two frames are fixedly connected to the arc surface of the sleeve. A snap-fit ​​groove is formed on the inner wall of the frame. The size of the snap-fit ​​groove is adapted to the size of the snap-fit ​​block. A movable plate is slidably connected to the inner wall of the frame.

[0019] The above technical solution facilitates the connection between two power pipes.

[0020] Furthermore, a square plate is fixedly connected to the surface of the frame, and a positioning pin is slidably connected to the inner wall of the square plate. Two circular holes are opened on the inner wall of the movable plate, and the size of the circular holes is adapted to the size of the positioning pin.

[0021] The above technical solution can fix the position of the moving plate.

[0022] Furthermore, a spring is fixedly connected to the side of the positioning pin that is close to the square plate.

[0023] The above technical solution enables the positioning pin to be quickly reset.

[0024] The above-described solution of this utility model has at least the following beneficial effects:

[0025] This utility model, by setting an adjustment mechanism, can adjust the height of the power pipe during the laying and installation of the power pipe, avoiding the situation where the height of the power pipe is inconsistent due to uneven foundation pit, thereby facilitating the installation by the staff and improving the practicality of the connection structure.

[0026] This invention, by setting a fixing mechanism, enables the quick fixing or separation of two power pipes, avoiding the need to carry tools to twist multiple bolts to fix or separate the power pipes, thus improving the work efficiency of the staff. Attached Figure Description

Detailed Implementation

[0035] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0036] like Figures 1 to 6 As shown, an embodiment of this utility model provides a high-voltage power pipe connection structure for power transmission, including a power pipe 1 and a power pipe 2; an adjustment mechanism 3, disposed on the surface of the power pipe 1 and the power pipe 2, for adjusting the height of the power pipe 1 and the power pipe 2; and a fixing mechanism 4, disposed on the surface of the power pipe 1 and the power pipe 2, for fixing the power pipe 1 and the power pipe 2.

[0037] like Figures 1 to 3 As shown, the adjustment mechanism 3 includes a support frame 301, which is movably installed with power pipe 1 and power pipe 2. Two fixing plates 307 are fixedly connected to the upper surface of the support frame 301. A lead screw 309 is threadedly connected to the inner wall of the fixing plate 307. An arc plate 310 is rotatably connected to one end of the lead screw 309. Two support rods 302 are slidably connected to the inner wall of the support frame 301. A base plate 303 is fixedly connected to the surface of the two support rods 302. A rotating rod 311 is rotatably connected to the inner wall of the support frame 301. A handle 306 is fixedly connected to one end of the rotating rod 311. A bevel gear 312 is fixedly connected to the other end of the rotating rod 311. A bevel gear 313 is rotatably connected to the inner wall of the support frame 301. The bevel gear 312 and the bevel gear 313 mesh with each other. A screw 314 is fixedly connected to the surface of the bevel gear 313. The screw 314 is threadedly connected to the support rod 302. When laying and installing power pipes, the workers place the adjustment mechanism 3 in the foundation pit, with the base plate 303 supported on the ground. First, power pipe 1 and power pipe 2 are placed on the corresponding support frame 301. The screw 309 on the fixing plate 307 is rotated, which drives the arc plate 310 to move and fit against the arc surface of the power pipe, thus fixing the power pipe on the support frame 301. Then, according to the height difference of the power pipes to be connected, the workers rotate the handle 306, which drives the bevel gear 312 to rotate through the rotating rod 311. Since bevel gear 312 and bevel gear 2 313 mesh with each other, bevel gear 2 313 rotates accordingly, which causes the screw 314 to move up and down in the support rod 302, thereby lifting the support frame 301 and adjusting the height of the power pipes to be connected, thus facilitating the connection of power pipe 1 and power pipe 2.

[0038] like Figures 1 to 3As shown, a rubber pad 305 is fixedly connected to the inner wall of the support frame 301. The presence of the rubber pad 305 increases the friction with the power pipe, thus preventing the possibility of scratches on the surface of the power pipe.

[0039] like Figures 1 to 3 As shown, a fixing rod 308 is fixedly connected to the surface of the arc plate 310, and the fixing rod 308 is slidably connected to the fixing plate 307. When the lead screw 309 drives the arc plate 310 to move, the presence of the fixing rod 308 means that the arc plate 310 can only move left and right.

[0040] like Figures 1 to 3 As shown, several spikes 304 are fixedly connected to the surface of the base plate 303. The spikes 304 are embedded in the soil, making the base plate 303 more stable.

[0041] In this embodiment of the utility model (working principle), by setting an adjustment mechanism 3, when laying and installing the power pipe, the worker places the adjustment mechanism 3 in the foundation pit. The spikes 304 on the base plate 303 will be embedded in the soil, thereby making the base plate 303 more stable. Power pipe 1 and power pipe 2 are placed on the corresponding support frame 301. The rubber pad 305 avoids direct contact between the support frame 301 and the power pipe, thus preventing damage. Then, the worker rotates the screw 309 on the fixing plate 307, causing the arc plate 310 to move and contact the surface of the power pipe. The fixing rod 308 allows the arc plate 310 to move only left and right, thus fixing the power pipe. Then, based on the height difference between the two power pipes, the operator rotates the handle 306, which drives the bevel gear 312 through the rotating rod 311. The bevel gear 312 then drives the bevel gear 313, which in turn drives the screw 314 to rotate inside the support rod 302. When the screw 314 rotates, it moves along the thread inside the support rod 302, thereby lifting the support frame 301, making it easier for the operator to fix and connect the power pipe 1 and the power pipe 2.

[0042] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the fixing mechanism 4 includes a connecting pipe 401, which is fixedly installed at one end of the power pipe 1. Two protrusions 403 are fixedly connected to the arc surface of the connecting pipe 401. A square groove 409 is opened on the inner wall of the protrusion 403. Several springs 408 are fixedly connected to the inner wall of the square groove 409. A snap-fit ​​block 404 is fixedly connected to one end of the springs 408. A sleeve 402 is fixedly installed at one end of the power pipe 2. Two frames 405 are fixedly connected to the arc surface of the sleeve 402. A snap-fit ​​groove 410 is opened on the inner wall of the frame 405. The size of the snap-fit ​​groove 410 is adapted to the size of the snap-fit ​​block 404. A movable plate 407 is slidably connected to the inner wall of the frame 405. When it is necessary to connect power pipe 1 and power pipe 2, lift the movable plate 407 to engage the connecting pipe 401 with the sleeve 402. The locking block 404 on the protrusion 403 is compressed by external force and the spring 408 is housed in the square groove 409, which then engages with the frame 405. At this time, the locking block 404 extends into the locking groove 410 in the frame 405 under the action of the spring 408, thereby fixing the position of the protrusion 403 and thus fixing the connection between power pipe 1 and power pipe 2. When it is necessary to separate power pipe 1 and power pipe 2, press the movable plate 407 to compress the locking block 404 and house it in the square groove 409, and then separate the protrusion 403 from the frame 405.

[0043] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a square plate 406 is fixedly connected to the surface of the frame 405. A positioning pin 412 is slidably connected to the inner wall of the square plate 406. Two round holes 411 are opened on the inner wall of the movable plate 407. The size of the round holes 411 matches the size of the positioning pin 412. When the movable plate 407 is not in use, the positioning pin 412 on the square plate 406 is pulled to engage with the round hole 411 on the movable plate 407 away from the handle. At this time, the movable plate 407 is away from the locking block 404. When the movable plate 407 is in use, the positioning pin 412 is engaged with the round hole 411 on the movable plate 407 near the handle. At this time, the movable plate 407 presses the locking block 404, causing it to be stored in the square groove 409.

[0044] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a spring 413 is fixedly connected to the side of the locating pin 412 that is close to the square plate 406. When the locating pin 412 needs to engage with the round hole 411, the spring 413 allows the locating pin 412 to quickly return to its original position.

[0045] In this embodiment of the utility model, by setting a fixing mechanism 4, when it is necessary to connect the power pipe 1 and the power pipe 2, the positioning pin 412 on the square plate 406 is pulled, and the moving plate 407 is lifted. Under the action of the spring 2 413, it engages with the round hole 411 on the moving plate 407 away from the handle. Then, the connecting pipe 401 is engaged with the sleeve 402. The locking block 404 on the protrusion 403 is squeezed by external force and the spring 1 408 is housed in the square groove 409, and then engages with the frame 405. At this time, the locking block 404 extends to the frame 405 under the elastic action of the spring 1 408. The position of the protrusion 403 is fixed in the slot 410 within 05, thereby fixing the connection between power pipe 1 and power pipe 2. When it is necessary to separate power pipe 1 and power pipe 2, pull the positioning pin 412 on the square plate 406 and press the moving plate 407 to engage the positioning pin 412 with the round hole 411 near the handle on the moving plate 407. At this time, the moving plate 407 squeezes the locking block 404, causing it to be stored in the square groove 409. Then, the protrusion 403 is separated from the frame 405, which allows power pipe 1 and power pipe 2 to be separated.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
