Description

Technical Field

[0001] The present invention relates to the technical field of distribution network frameworks, and specifically to a distribution network framework for the integrated planning of a distribution network. Background Art

[0002] The distribution network framework is the basis for the integrated planning of the distribution network. The distribution network framework plays a crucial role in the integrated planning of the distribution network. It is not only a channel for power transmission and distribution, but also determines the reliability, flexibility, and economy of the power grid. It mainly consists of utility poles, transformers, crossbars, insulators, and cables. During installation, the cable needs to be connected to the insulator on the crossbar and then to the transformer.

[0003] However, when the existing distribution network framework for the integrated planning of the distribution network is in use, since the insulator on the crossbar is in the middle position, when an operator is making a connection, they need to climb on the utility pole and lean sideways to perform the operation, which poses a relatively high safety risk and is not safe and reliable enough. Summary of the Invention

[0004] The purpose of the present invention is to provide a distribution network framework for the integrated planning of a distribution network to solve the problems raised in the above background art.

[0007] Preferably, the lifting component includes moving rods fixedly connected to the ends of the respective tapered rods, and the other ends of the moving rods penetrate through the U-shaped plate. First springs are sleeved on the side walls of the moving rods, and limiting mechanisms for limiting the moving rods are provided at the top and bottom of the U-shaped plate.

[0008] Preferably, the limiting mechanism includes discs fixedly connected to the ends of the respective moving rods, and two symmetrically arranged limiting plates are slidably connected to the top and bottom of the U-shaped plate. A plurality of arrayed limiting grooves are formed in the side wall of the limiting plate, and a connecting frame is fixedly connected between the limiting plate and the L-shaped plate.

[0009] Preferably, the telescopic mechanism includes two symmetrically arranged first sleeve rods fixedly connected to the side wall of the U-shaped plate, and a first sleeve is sleeved on the side wall of each first sleeve rod. The other end of the first sleeve is fixedly connected to the side wall of the L-shaped plate, and a return spring is sleeved on the side wall of each first sleeve.

[0010] Preferably, the moving mechanism includes a fixing plate fixedly connected to the side wall of the operation frame, and a second sleeve rod is fixedly connected to the side wall of the fixing plate. A second sleeve is sleeved on the side wall of the second sleeve rod, and the other end of the second sleeve is fixedly connected to the side wall of the L-shaped plate. A threaded rod is rotatably connected to the side wall of the fixing plate, and a threaded tube is threadedly connected to the side wall of the threaded rod, and the other end of the threaded tube is fixedly connected to the side wall of the L-shaped plate.

[0011] Preferably, a handwheel is rotatably connected to the side wall of the fixing plate through a rotating shaft, and one end of the rotating shaft is fixedly connected to one end of the threaded rod.

[0012] Preferably, the moving assembly includes two symmetrically arranged first T-shaped guide rods fixedly connected to the side wall of the operation frame, and a moving block is sleeved on the side wall of the first T-shaped guide rod. The moving block is fixedly connected to the side wall of the baffle. A second spring is sleeved on the side wall of each first T-shaped guide rod, and a limiting assembly for limiting the moving block is arranged on the side wall of the operation frame.

[0013] Preferably, the limiting assembly includes a moving plate, and the moving plate is connected to the side wall of the operation frame through a reset mechanism. Two symmetrically arranged triangular blocks are fixedly connected to the bottom of the moving plate, and each triangular block includes two symmetrically arranged inclined surfaces.

[0014] Preferably, the reset mechanism includes two symmetrically arranged second T-shaped guide rods fixedly connected to the top of the moving plate, and a connecting plate is sleeved on the side wall of the second T-shaped guide rod. The connecting plate is fixedly connected to the side wall of the operation frame, and a third spring is sleeved on the side wall of each second T-shaped guide rod.

[0015] Preferably, a fixing rod is fixedly connected to the side wall of the baffle, and a rubber sleeve is fixedly sleeved on the side wall of the fixing rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The power distribution network framework for the integrated planning of the power distribution network is provided with a sliding mechanism. When it is necessary to connect and fix the cable to the insulator, first place the operation box and the U-shaped plate on both sides of the cross bar, and make the third ball on the side wall of the operation box abut against the side wall of the cross bar. Then, rotate the hand wheel. The rotation of the hand wheel drives the rotation of the threaded rod, thereby driving the threaded pipe and the second sleeve to move towards the fixing plate. At the same time, the U-shaped plate can be driven to move synchronously through the L-shaped plate and the telescopic mechanism. When the tapered rod abuts against the side wall of the cross bar, the two tapered rods in the same group can be pushed to move away from each other. At the same time, the first spring is gradually compressed, so that the first ball can slide on the top and bottom of the cross bar. When the second ball abuts against the side wall of the cross bar, the U-shaped plate stops moving. When the L-shaped plate continues to move, it can push the first sleeve to slide along the side wall of the first sleeve rod. At the same time, the return spring is compressed, and the limiting plate can be driven to move through the connecting frame, and the disc is inserted into the limiting groove for limiting. At this time, the connection between the operation box and the cross bar can be realized, and at the same time, it is ensured that the operation box can slide on the cross bar. Then, the operator pushes the baffle through the fixing rod, so that the operation box can be opened. At the same time, when the baffle moves, the moving block can be driven to move synchronously along the first T-shaped guide rod, and the second spring is compressed. When the moving block abuts against the inclined surface of the triangular block, the moving plate can be pushed to move upward, and the third spring is compressed. When the moving block passes over the triangular block, the triangular block can move downward under the action of the third spring to limit the moving block, and then limit the baffle. Then, the operator can enter the operation box. After standing in the operation box, the baffle can be pushed to close through the fixing rod and can be limited under the action of the limiting component. And the operator can make the U-shaped plate slide on the cross bar, thereby driving the operation box to move, and then adjusting the standing position to facilitate the connection of the cable to the insulator, which is safer and more reliable.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-8 , the present invention provides a technical solution: A distribution network frame for the integrated planning of a distribution network includes an electric pole 101, a transformer 102, and an L-shaped cross bar 103 provided on the distribution network frame body 1. The side wall of the cross bar 103 is fixedly connected with an insulator 104, and a cable 105 is connected between the transformer 102 and the insulator 104. The side wall of the cross bar 103 is detachably connected with an operation frame 11 through a sliding mechanism 14, and a baffle 12 is connected to the side wall of the operation frame 11 through a moving assembly 8;

[0029] The sliding mechanism 14 includes a U-shaped plate 1401, and multiple sets of tapered rods 1402 are connected to the top and bottom of the U-shaped plate 1401 through a lifting assembly 2. The number of tapered rods 1402 in each group is two, and first balls 1403 are arranged at the opposite ends of each group of tapered rods 1402. A plurality of second balls 1404 are arranged in an array on the side wall of the U-shaped plate 1401. The side wall of the U-shaped plate 1401 is connected to an L-shaped plate 1405 through a telescopic mechanism 3. A plurality of third balls 1406 are arranged in an array on the side wall of the operation frame 11. A moving mechanism 5 is arranged between the L-shaped plate 1405 and the operation frame 11, which can connect the operation frame 11 to the cross bar 103 and can move on the cross bar 103. At this time, the operator stands on the operation frame 11 and moves through the operation frame 11 to adjust the standing position, so as to connect the cable 105 to the insulator 104 more safely and reliably.

[0030] The lifting assembly 2 includes moving rods 201 fixedly connected to the ends of the respective tapered rods 1402. The other ends of the moving rods 201 penetrate through the U-shaped plate 1401. A first spring 202 is sleeved on the side wall of the moving rod 201. Limiting mechanisms 4 for limiting the movement of the moving rod 201 are arranged at the top and bottom of the U-shaped plate 1401, which play a role in guiding and resetting the movement of the moving rod 201.

[0031] The limiting mechanism 4 includes discs 401 fixedly connected to the ends of the respective moving rods 201. Two symmetrically arranged limiting plates 402 are slidably connected to the top and bottom of the U-shaped plate 1401. A plurality of limiting grooves 403 are arranged in an array on the side wall of the limiting plate 402. A connecting frame 404 is fixedly connected between the limiting plate 402 and the L-shaped plate 1405. When the second ball 1404 abuts against the side wall of the cross bar 103, the U-shaped plate 1401 stops moving. When the L-shaped plate 1405 continues to move, it can drive the limiting plate 402 to move through the connecting frame 404 and insert the disc 401 into the limiting groove 403 for limiting.

[0032] The telescopic mechanism 3 includes two symmetrically arranged first sleeve rods 301 fixedly connected to the side wall of the U-shaped plate 1401. A first sleeve 302 is sleeved on the side wall of each first sleeve rod 301. The other end of the first sleeve 302 is fixedly connected to the side wall of the L-shaped plate 1405. A return spring 303 is sleeved on the side wall of each first sleeve 302. When the second ball 1404 abuts against the side wall of the cross bar 103, the U-shaped plate 1401 stops moving. When the L-shaped plate 1405 continues to move, it can push the first sleeve 302 to slide along the side wall of the first sleeve rod 301, and at the same time, the return spring 303 is compressed.

A second sleeve 503 is sleeved on the side wall of the second sleeve rod 502, and the other end of the second sleeve 503 is fixedly connected to the side wall of the L-shaped plate 1405. A threaded rod 504 is rotatably connected to the side wall of the fixing plate 501. A threaded tube 505 is threadedly connected to the side wall of the threaded rod 504, and the other end of the threaded tube 505 is fixedly connected to the side wall of the L-shaped plate 1405. The rotation of the threaded rod 504 drives the threaded tube 505 and the second sleeve 503 to move towards the fixing plate 501. At the same time, the U-shaped plate 1401 can be driven to move synchronously through the L-shaped plate 1405 and the telescopic mechanism 3.

[0034] A rocker 6 is rotatably connected to the side wall of the fixing plate 501 through a rotating shaft, and one end of the rotating shaft is fixedly connected to one end of the threaded rod 504. By rotating the rocker 6, the rotation of the rocker 6 drives the rotation of the threaded rod 504.

[0035] The moving assembly 8 includes two symmetrically arranged first T-shaped guide rods 801 fixedly connected to the side wall of the operation box 11. A moving block 802 is sleeved on the side wall of the first T-shaped guide rod 801. The moving block 802 is fixedly connected to the side wall of the baffle 12. A second spring 803 is sleeved on the side wall of each first T-shaped guide rod 801. And a limiting assembly 9 for limiting the moving block 802 is arranged on the side wall of the operation box 11, which plays a role in guiding and resetting the movement of the baffle 12.

[0036] The limiting assembly 9 includes a moving plate 901, and the moving plate 901 is connected to the side wall of the operation box 11 through a reset mechanism 10. Two symmetrically arranged triangular blocks 902 are fixedly connected to the bottom of the moving plate 901. Each triangular block 902 includes two symmetrically arranged inclined surfaces 903. When the moving block 802 abuts against the inclined surface 903 of the triangular block 902, the moving plate 901 can be pushed to move upward. When the moving block 802 passes over the triangular block 902, the triangular block 902 can move downward under the action of the reset mechanism 10, and the moving block 802 can be limited.

[0037] The reset mechanism 10 includes two symmetrically arranged second T-shaped guide rods 1002 fixedly connected to the top of the moving plate 901. A connecting plate 1001 is sleeved on the side wall of the second T-shaped guide rod 1002. The connecting plate 1001 is fixedly connected to the side wall of the operation box 11. And a third spring 1003 is sleeved on the side wall of each second T-shaped guide rod 1002, which plays a role in guiding and resetting the movement of the moving plate 901.

[0038] A fixing rod 7 is fixedly connected to the side wall of the baffle 12, and a rubber sleeve is fixedly sleeved on the side wall of the fixing rod 7. The operator pushes the baffle 12 through the fixing rod 7.

[0039] Working principle: When in use, when it is necessary to connect and fix the cable 105 to the insulator 104, first place the operation frame 11 and the U-shaped plate 1401 on both sides of the cross bar 103 so that the third ball 1406 on the side wall of the operation frame 11 abuts against the side wall of the cross bar 103;

[0040] Next, rotate the handwheel 6. The rotation of the handwheel 6 drives the rotation of the threaded rod 504, thereby driving the threaded tube 505 and the second sleeve 503 to move in the direction close to the fixed plate 501. At the same time, the U-shaped plate 1401 can be driven to move synchronously through the L-shaped plate 1405 and the telescopic mechanism 3. When the tapered rod 1402 abuts against the side wall of the cross bar 103, the two tapered rods 1402 in the same group can be pushed to move away from each other. At the same time, the first spring 202 is gradually compressed, so that the first ball 1403 can slide on the top and bottom of the cross bar 103. When the second ball 1404 abuts against the side wall of the cross bar 103, the U-shaped plate 1401 stops moving. When the L-shaped plate 1405 continues to move, it can push the first sleeve 302 to slide along the side wall of the first sleeve rod 301. At the same time, the return spring 303 is compressed, and the limiting plate 402 can be driven to move through the connecting frame 404, and the disc 401 is inserted into the limiting groove 403 for limiting. At this time, the connection between the operation frame 11 and the cross bar 103 can be realized, and at the same time, it is ensured that the operation frame 11 can slide on the cross bar 103;

[0041] Next, the operator pushes the baffle 12 through the fixed rod 7, so that the operation frame 11 can be opened. At the same time, when the baffle 12 moves, the moving block 802 can be driven to move synchronously along the first T-shaped guide rod 801. At the same time, the second spring 803 is compressed. When the moving block 802 abuts against the inclined surface 903 of the triangular block 902, the moving plate 901 can be pushed to move upward. At the same time, the third spring 1003 is compressed. When the moving block 802 passes over the triangular block 902, the triangular block 902 can move downward under the action of the third spring 1003, and the moving block 802 can be limited, and then the baffle 12 can be limited. Then, the operator can enter the operation frame 11;

[0042] After standing inside the operation frame 11, the baffle 12 can be pushed to close through the fixed rod 7 and can be limited under the action of the limiting component 9. And the operator can make the U-shaped plate 1401 slide on the cross bar 103, thereby driving the operation frame 11 to move, and then adjusting the standing position, so as to connect the cable 105 to the insulator 104, which is safer and more reliable.
