[0003] There is a prior line protection device for electrical engineering and its automation (Publication No.: CN216121750U), which includes a base assembly. A buffer mechanism is fixedly connected inside the base assembly, and a first connecting block is fixedly connected to the left side of the cover plate. The utility model is provided with a buffer mechanism and a limiting mechanism. The outer side of the device is designed into two structures that can be flipped over each other. At the same time, a buffer mechanism and a pressing plate are added between the base and the cover plate. On the one hand, the pipeline can be installed into the two groups of buffer mechanisms, and the pipeline is clamped by the first spring. According to the stretching stroke of the spring, pipelines with various different diameters can be installed within the stroke. On the other hand, it can play a role in buffering and shock absorption, preventing the pipeline from bursting due to long-term extrusion. At the same time, through the cooperation between the limiting mechanism and the limiting block, the rapid opening and closing between the base and the cover plate are realized, which is convenient for operation, and the structure is simple and practical, greatly improving the practicability.

[0021] A line protection device for electrical engineering includes a splicing quick-disassembly maintenance pipe 1. A maintenance cover 2 is arranged on the outer wall of the splicing quick-disassembly maintenance pipe 1. Cable clamping assemblies 3 are evenly arranged in the splicing quick-disassembly maintenance pipe 1. At both ends of the splicing quick-disassembly maintenance pipe 1, there are quick splicing assemblies 4 that can be mutually matched and clamped. The quick splicing assembly 4 includes a fixed ring 401 that can slide horizontally along the axis of one end of the splicing block disassembly maintenance pipe and a positioning circular ring frame 402 fixedly installed at the other end of the quick splicing assembly 4.

[0022] As Figure 2 and Figure 5 shown, a cover hole 5 is opened on one outer wall of the splicing quick-disassembly maintenance pipe 1. The maintenance cover 2 is hinged to the cover hole 5. Preferably, both sides of the lower part of the maintenance cover 2 are hinged to the cover hole 5. The maintenance cover 2 can be matched and buckled in the cover hole 5. The main body of the maintenance cover 2 is of an arc-shaped structure;

[0023] As Figure 5 shown, the cable clamping assembly 3 includes arc-shaped clamping plates 301 symmetrically arranged inside the splicing quick-disassembly maintenance pipe 1. Elastic members 302 are linearly and fixedly installed on one side surface of each arc-shaped clamping plate 301. At the same time, the elastic members 302 can be spring telescopic rods, elastic rubbers, etc. If the elastic member 302 is a spring-type telescopic rod with a model number of GH-031, one ends of the elastic members 302 are fixedly connected to the circumferential inner wall of the splicing quick-disassembly maintenance pipe 1 respectively, so that through the mutual cooperation of the elastic members 302 and the arc-shaped clamping plates 301, different diameters of cables can be installed inside the device. At the same time, through the elastic characteristics of the elastic members 302, certain protection can be provided for the cables, thereby reducing the problem that the cables are damaged due to excessive extrusion.

[0024] As Figures 2 - 4As shown in the figure, the fixed ring 401 is sleeved on the outer circumferential wall of one end of the splicing quick-release maintenance pipe 1. The outer circumferential wall of one end of the splicing quick-release maintenance pipe 1 is symmetrically provided with limiting T-shaped grooves. The inner circumferential walls of one end of the fixed ring 401 are symmetrically and fixedly installed with limiting T-shaped long plates 403. The T-shaped grooves are symmetrically arranged on the upper and lower outer walls of one end of the splicing quick-release maintenance pipe 1. The limiting T-shaped long plates 403 are arranged in the T-shaped grooves. The T-shaped grooves are "T"-shaped grooves. The limiting T-shaped long plates 403 are slidably clamped with the limiting T-shaped grooves. Figure 2 ); The outer surface of the fixed ring 401 is symmetrically provided with a positioning ring 405 with positioning blocks 404 on the outer wall. The outer circumferential wall of the fixed ring 401 is fixedly installed with a limiting ring 406. The inner circumferential wall of the positioning ring 405 is provided with an annular groove. The fixed ring 401 is rotatably clamped with the positioning ring 405 with the annular groove through the limiting ring 406. The outer wall of one end of the positioning circular ring frame 402 is symmetrically and throughly provided with insertion holes 407. The cross-section of the insertion holes 407 is in a "U" shape. The inner wall of one end of the positioning circular ring frame 402 is provided with a positioning groove 408. The inner wall of the other end of the positioning circular ring frame 402 is fixedly installed with a positioning spring 409. One end of the positioning spring 409 is fixedly installed with a gasket 410. When the staff passes the cable into the splicing quick-release maintenance pipe 1, at this time, the staff slides and clamps the positioning ring 405 at one end of a splicing quick-release maintenance pipe 1 through the sliding connection between the limiting T-shaped long plate 403 on the inner wall of the fixed ring 401 and the limiting T-shaped groove, so that the positioning block 404 on the positioning ring 405 is inserted into the positioning circular ring frame 402 at one end of the next splicing quick-release maintenance pipe 1. At this time, the positioning block 404 is inserted into the positioning circular ring frame 402 along the direction of the insertion hole 407. Then, the rocker arranged on the positioning ring 405 is rotated at this time. At this time, the positioning ring 405 starts to rotate. When the positioning block 404 on the positioning ring 405 is matched and clamped with the positioning groove 408 opened on the inner wall of one end of the positioning circular ring frame 402, at this time, the positioning spring 409 and the gasket 410 squeeze one end of the positioning ring 405, thereby realizing the quick splicing of the splicing quick-release maintenance pipe 1, and thus facilitating the staff to transport the device.
