Technical Field

[0001] The utility model relates to a cable supporting and protecting device for an electric power system, belonging to the technical field of electric power equipment. Background Art

[0002] At present, the power system is an electric energy production and consumption system composed of power plants, transmission and transformation lines, power supply and distribution stations and power consumption. Its function is to convert the primary energy in nature into electric energy through power generation devices, and then supply the electric energy to various users through transmission, transformation and distribution. In order to achieve this function, the power system also has corresponding information and control systems in various links and different levels to measure, adjust, control, protect, communicate and dispatch the production process of electric energy to ensure that users obtain safe and high-quality electric energy. When the wires or cables used in the power system need to be installed indoors or outdoors, special cable support and protection devices are often required to install the wires and cables at high places to improve safety.

[0003] However, when the cables are laid, the supporting and protecting device provides point-type support for the cables. Therefore, there will be a section of the cable in the air between the two points. This section is easy to contact with external objects, causing the cable to stretch. Under excessive tension, the cable is easy to be broken, causing danger. For this reason, we propose a cable supporting and protecting device for the power system.

[0004] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a cable support protection device for power systems to make it more valuable for industrial use. Summary of the invention

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a cable support protection device for an electric power system.

[0006] The utility model discloses a cable support and protection device for an electric power system, comprising a base, a column is arranged on the upper surface of the base, a protection box is arranged on the right side of the column, and a telescopic mechanism is arranged inside the protection box, the telescopic mechanism comprises a fixed plate, and the fixed plate is arranged in the middle of the protection box, telescopic rods are arranged inside the left and right sides of the fixed plate, and the circumferential surface of the telescopic rod is sleeved with a return spring, a clamping plate is arranged at one end of the telescopic rod away from the fixed plate, and four clamping plates are arranged, and tooth plates are arranged on the inner surfaces of the clamping plate at the front end on the right side and the rear end on the left side, the tooth plates are meshingly connected with gears, and a winding rod is arranged in the middle of the gears.

[0007] Furthermore, the interiors of the two front end clamping plates are both threadedly connected with the second threaded rod, the interiors of the two rear end clamping plates are both threadedly connected with the third threaded rod, and the rear end of the second threaded rod is connected to the front end of the third threaded rod.

[0008] Furthermore, a first sliding groove is provided on the side wall of the fixed plate, the telescopic rod is slidably installed inside the first sliding groove, a second sliding groove is provided on the front side of the protective box, the front end of the second threaded rod is slidably installed inside the second sliding groove, a third sliding groove is provided on the rear inner wall of the protective box, and a sliding block is slidably installed inside the third sliding groove, and the rear end of the third threaded rod is rotatably installed inside the sliding block.

[0009] Furthermore, a lifting mechanism is provided inside the column, and the lifting mechanism includes a motor, and the motor is arranged at the inner bottom of the column, the power output end of the motor is transmission-connected with a first threaded rod, the circumferential surface of the first threaded rod is threadedly connected with a lifting plate, the protection box is arranged at the right end of the upper surface of the lifting plate, and a battery is arranged at the right end of the inner bottom of the column, and the battery is electrically connected to the motor.

[0010] By means of the above scheme, the present invention has at least the following advantages:

[0011] (1) The cable support protection device for the power system can, through the telescopic mechanism, when the cable arranged on the outside of the protection box is pulled by external force, the reeling rod inside the protection box can unwind the cable wound on its surface, thereby preventing the cable from being pulled by excessive external force and causing breakage. After the external force disappears, the reset spring can reset the cable, allowing the reeling rod to rewind the cable, and then the cable is still in a straightened state, thereby preventing the cable outside the protection box from bending and affecting the use effect.

[0012] (2) The power system uses a cable to support the protection device. Through the provided lifting mechanism, the protection box can be moved from the upper end of the column to the lower end without removing the cable, which is convenient for workers to perform maintenance without the need for workers to work at height, thus reducing the danger during work.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] See also Figure 1 - Figure 4 The utility model provides a cable support and protection device for an electric power system, comprising a base 1, a column 2 is arranged on the upper surface of the base 1, a protection box 3 is arranged on the right side of the column 2, a lifting mechanism 4 is arranged inside the column 2, the lifting mechanism 4 comprises a motor 401, and the motor 401 is arranged at the inner bottom of the column 2, the power output end of the motor 401 is connected to the first threaded rod 402 through a coupling transmission, the circumferential surface of the first threaded rod 402 is threadedly connected to the lifting plate 403, the protection box 3 is arranged at the right end of the upper surface of the lifting plate 403, a battery is arranged at the right end of the inner bottom of the column 2, and the battery is electrically connected to the motor 401. The battery can provide power to the motor 401, so that the motor 401 can work smoothly. When it is necessary to repair the inside of the protection box 3, the motor 401 is started, and the motor 401 drives the first threaded rod 402 to rotate, so that the lifting plate 403 drives the protection box 3 to move vertically downward, and then the protection box 3 can be lowered to a suitable position, and the protection box 3 can be repaired without the need for workers to climb up;

[0022] A telescopic mechanism 5 is provided inside the protection box 3, and the telescopic mechanism 5 includes a fixed plate 501, and the fixed plate 501 is arranged in the middle of the protection box 3, and two fixed plates 501 are symmetrically arranged in front and back, and the two fixed plates 501 are respectively connected to the front wall and the rear wall inside the protection box 3, and telescopic rods 502 are provided inside the left and right sides of the fixed plate 501, and the circumferential surface of the telescopic rod 502 is sleeved with a return spring 503, and the side wall of the fixed plate 501 is provided with a first slide groove 6, and the telescopic rod 502 is slidably installed inside the first slide groove 6. The setting of the first slide groove 6 provides a movable space for the telescopic rod 502, so that the telescopic rod 502 can smoothly move horizontally forward and backward;

[0023] The end of the telescopic rod 502 away from the fixed plate 501 is provided with a clamping plate 504, and the clamping plates 504 are provided with four, among which one end of the return spring 503 is in contact with the fixed plate 501, and the other end is fixedly connected to the clamping plate 504, so that the clamping plate 504 can smoothly move horizontally forward and backward, and reset after horizontally moving left and right. The two clamping plates 504 on the left can clamp and fix the left end of the cable, and the two clamping plates 504 on the right can clamp and fix the right end of the cable. Then, when the cable is pulled, the cable can drive the clamping plates 504 to move horizontally left and right together. The inner surfaces of the right front end clamping plate 504 and the left rear end clamping plate 504 are both provided with toothed plates 505, and the toothed plates 505 are meshedly connected with teeth. Wheel 506, a winding rod 507 is arranged in the middle of gear 506, and the arrangement of the two tooth plates 505 here can drive the gear 506 to rotate counterclockwise when the clamping plate 504 is away from the gear 506, so that the winding rod 507 can unwind. Similarly, when the clamping plate 504 approaches the gear 506 in the opposite direction, the winding rod 507 performs winding. The interiors of the two front clamping plates 504 are both threadedly connected with a second threaded rod 508, and a second slide groove 7 is provided on the front side of the protection box 3. The front end of the second threaded rod 508 is slidably installed in the interior of the second slide groove 7. The arrangement of the second slide groove 7 provides the second threaded rod 508 with a movable space, so that the second threaded rod 508 can smoothly move horizontally left and right;

[0024] The interiors of the two rear end clamping plates 504 are both threadedly connected with a third threaded rod 509, and the rear end of the second threaded rod 508 is connected to the front end of the third threaded rod 509. A third sliding groove 8 is provided on the rear inner wall of the protection box 3, and a slider 9 is slidably installed inside the third sliding groove 8. The rear end of the third threaded rod 509 is rotatably installed inside the slider 9. The setting of the third sliding groove 8 provides space for the slider 9 to move, so that the slider 9 can move horizontally left and right smoothly. The setting of the slider 9 can limit the third threaded rod 509 without affecting the rotation of the third threaded rod 509.

[0025] The working principle and use process of the utility model are as follows: when installing the cable, the second threaded rod 508 is first rotated, so that the third threaded rod 509 rotates with the second threaded rod 508, and then the clamping plates 504 on the front and rear sides are driven to move toward the cable and clamp and fix the cable. At this time, the cable and the clamping plates 504 are a whole. Then, when the cable is pulled by external force, the cable will drive the clamping plate 504 away from the winding rod 507, and the winding rod 507 rotates and unwinds to prevent the cable from breaking due to excessive tension. After the cable is not pulled by external force, the clamping plate 504 is moved toward the winding rod 507 by the force of the reset spring 503 and returns to its initial position, thereby driving the cable to return to its initial state. At the same time, the toothed plate 505 drives the gear 506 and the winding rod 507 to rotate clockwise, so that the winding rod 507 rewinds the cable, avoiding the danger caused by the cable being placed arbitrarily inside the protective box 3.
