Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for maintenance work in hydropower stations, in particular to a magnetic flexible protective tube for casings. Background Art

[0002] The high-voltage bushing is a current-carrying component that leads the high-voltage lead of the transformer outside the oil tank to achieve connection with the external power grid, and also serves as a fixed lead. The high-voltage bushing is installed on the high-voltage bushing riser, and its lower end is inside the high-voltage bushing riser.

[0003] See also Figure 5 A ceramic insulating tube 30 is installed in the high-voltage bushing raising seat 10, and a docking flange 20 is provided on the top of the high-voltage bushing raising seat 10. Figure 6 During maintenance, the high-voltage bushing 40 installed in the high-voltage bushing lifting seat 10 needs to be removed and reinstalled. Since the high-voltage bushing 40 is heavy and high in height, the high-voltage bushing 40 will inevitably shake when it is removed and installed from the high-voltage bushing lifting seat 10. When the high-voltage bushing 40 collides with the ceramic insulating tube 30, the ceramic insulating tube 30 will be broken. Therefore, during each operation, multiple people are required to hold the high-voltage bushing 40 to prevent collision, but the collision risk is still high. Utility Model Content

[0021] A high-voltage bushing riser 10 , a docking flange 20 , a sealing ring groove 21 , a ceramic insulating tube 30 , and a high-voltage bushing 40 . DETAILED DESCRIPTION

[0022] like Figure 1-6 As shown, a magnetic flexible protective tube for bushing includes a bottom plate 1, a magnetic piece 3 and an anti-collision block 4. The bottom plate 1 is made of flexible material. A plurality of anti-collision blocks 4 are arranged at the lower part of one side of the bottom plate 1. The anti-collision blocks 4 have a certain elasticity. A plurality of magnetic pieces 3 are arranged at the upper part of the bottom plate 1. An opening 12 is arranged on the bottom plate 1 between adjacent magnetic pieces 3. The opening 12 extends to the upper end of the anti-collision block 4. The magnetic piece 3 is used to be adsorbed onto the docking flange 20, so as to fix the bottom plate 1 in the ceramic insulating tube 30. A plurality of anti-collision blocks 4 are arranged at the lower part of one side of the bottom plate 1. When in use, the anti-collision blocks 4 surround the inner wall of the ceramic insulating tube 30. If a collision occurs, the collision of the high-voltage bushing 40 with the ceramic insulating tube 30 can be buffered, thereby reducing the risk of collision during operation.

[0023] In this embodiment, the bottom plate 1 can be made of a rubber plate, and the anti-collision block 4 can be made of a rubber block or a wooden block. When the anti-collision block 4 is made of a wooden block, the wooden block is mounted on the bottom plate 1 by bolts, and when a rubber block is used, it can be integrally formed with the bottom plate 1. At the same time, the magnetic member 3 can be made of a rubber magnetic strip structure, and the magnetic member 3 can be integrally formed with the bottom plate 1, or can be riveted and fixed to the bottom plate 1 by overlapping it for a certain distance.

[0024] In a preferred solution, the bottom plate 1 can also be made of cloth. When cloth is used, a plurality of receiving bags 2 are sewn on the bottom plate 1. The upper ends of the receiving bags 2 are open, and the anti-collision blocks 4 are movably inserted into the receiving bags 2. Such a structure has the following two advantages: first, it makes the manufacture of the device simpler and the installation of the anti-collision blocks 4 more convenient; second, it can be downwardly compatible with high-voltage bushing raising seats 10 of different diameters. When the diameter of the high-voltage bushing raising seat 10 becomes smaller, some anti-collision blocks 4 can be pulled out, so that the overlapping parts only increase the thickness of the cloth.

[0025] See also Figure 3 The upper end of the anti-collision block 4 is provided with a chamfer 41 on the side away from the bottom plate 1, so that the inner top of the anti-collision block 4 has a guiding inclined surface.

[0026] Since the sealing ring groove 21 is provided on the docking flange 20, the sealing ring groove 21 will affect the adhesion of the magnetic member 3, so the bottom plate 1 is further provided with an extension section 11 between the magnetic member 3 and the anti-collision block 4, see Figure 5 , 6 By providing the extension section 11 , the anti-collision block 4 can be adsorbed on the outer side of the sealing ring groove 21 when in use.

[0027] In a preferred embodiment, the magnetic member 3 is a rubber magnetic strip. When the bottom plate 1 is a rubber plate, the magnetic member 3 adopts a rubber magnetic strip structure, and the magnetic member 3 can be integrally formed with the bottom plate 1, or can overlap the bottom plate 1 for a distance and be riveted and fixed.

[0028] In another embodiment, when the base plate 1 is made of cloth, a plurality of mounting pockets 5 are sewn on the base plate 1 , and the magnetic members 3 are magnets, which are enclosed in the mounting pockets 5 .

[0029] The action process or principle of the utility model is as follows:

[0030] When using, see Figure 6 , the magnetic member 3 is adsorbed on the docking flange 20 in turn, and the anti-collision block 4 is placed inside the ceramic insulating tube 30, so as to form a flexible protection inside the ceramic insulating tube 30.

[0031] When the diameter of the high-voltage bushing lifting seat 10 becomes smaller, some anti-collision blocks 4 can be withdrawn, and the overlapping part only increases the thickness of the cloth.
