[0024] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0025] 1. A pressure-resistant component is provided. The first layer of pressure can be released through the strength and elastic deformation of the wear-resistant rubber sleeve itself. At this time, the wear-resistant rubber sleeve will further squeeze the foamed silica gel inside the polyethylene vacuum sleeve to unload the force during extrusion. The rear egg-shaped curved frame, the middle egg-shaped curved frame and the front egg-shaped curved frame inside the hexagonal force-equalizing frame will bear the pressure. At this time, the external pressure will be dispersed through the rear egg-shaped curved frame, the middle egg-shaped curved frame and the front egg-shaped curved frame, so that the pressure will be evenly transmitted to the pressure-resistant filler through the structural characteristics of the rear egg-shaped curved frame, the middle egg-shaped curved frame and the front egg-shaped curved frame, and then the pressure will be evenly transmitted to various places inside the cable by these pressure-resistant fillers, so as to complete the final unloading;

[0026] When the cable is used in conjunction with large machinery, it is inevitable that vehicles will pass through the site. No matter where the compressive force is transmitted from, one of the rear egg-shaped curve frame, the middle egg-shaped curve frame and the front egg-shaped curve frame will disperse the compressive force, and multiple sets of rear egg-shaped curve frames, middle egg-shaped curve frames and front egg-shaped curve frames are provided to more stably support and protect the internal power transmission cells, prevent cable damage, and further ensure the normal and stable operation of large machinery, thereby ensuring construction efficiency.

[0027] 2. A hexagonal force-equalizing frame, a pressure-resistant tube, a clamping groove, a rear fixing plate, a pressure-resistant filler, a fixed threaded hole, a front fixing plate and a fixed screw are provided to prevent the rear egg-shaped curved frame, the middle egg-shaped curved frame and the front egg-shaped curved frame from being displaced during pressure relief work. At this time, it can be ensured that when under pressure, the rear egg-shaped curved frame, the middle egg-shaped curved frame and the front egg-shaped curved frame will all be deformed outward from the middle in the same direction, thereby ensuring that the pressure can be evenly transmitted to the inside of the cable, further preventing the deformation and damage of the transmission core, and improving the stability of the cable use.

[0028] 3. A fixing component is provided. First, one of the angle adjustment plates is attached to the surface of the large machinery, and then a magnet is used to preliminarily fix the position. Next, the rotation angle of the limit rotation plate is adjusted according to the size of the installation position to adjust the sliding position of the sliding sleeve on the outside of the positioning sleeve. After the position of the sliding sleeve is determined, the other angle adjustment plates are fixed at the cable installation position of the large machinery. After the angle adjustment plates are fixed, the limit nut is re-tightened on the outside of the limit screw to fix the position of the sliding sleeve. At this time, when people move the large machinery, the high-voltage cable can be prevented from falling off due to excessive weight, thereby ensuring that the high-voltage cable can always supply power stably and preventing the interruption of the project progress due to unstable power supply during the project.

[0029] To sum up, during the use of the cable, the angle adjustment plate is fixed to the engineering machinery to ensure that the cable will not fall off, thereby ensuring stable power supply when the machinery is moving. The wear-resistant rubber sleeve can prevent the outer side of the cable from being worn and cracked during movement. Even if it is cracked, the damaged part can be sealed by the expansion of the foamed silicone, so that the cable does not need to be disassembled and repaired immediately. During the use of the cable, the limitations of the cable itself will not cause limitations to the project, and the working range of the engineering machinery can be increased to improve the diversity of use of the engineering machinery.

The inner side of the rotation groove 307 is rotatably installed with a limiting rotation plate 309, so as to facilitate fixing the angle adjustment plate 311.

[0055] The working principle and use process of the present invention are as follows: First, when the operator preburies the cable underground for use, although the cable is in the pipeline, the pipeline is also filled with various other types of cables, and when people are threading the cables, it is inevitable that the high-voltage cable will be squeezed. At this time, the wear-resistant rubber sleeve 220 will first be subjected to the first impact. The first layer of pressure can be released through the wear-resistant rubber sleeve 220's own strength and elastic deformation, and at this time, the wear-resistant rubber sleeve 220 will further squeeze the foamed silica gel 217 inside the polyethylene vacuum sleeve 217 during squeezing. 18 is used to unload the force, thereby preventing the influence of local pressure changes on the cable during threading. Then, when the pre-buried pipeline is damaged by natural disasters, a large amount of soil will exert pressure on the cable from all directions. At this time, after the pressure is unloaded by the wear-resistant rubber sleeve 220 and the foamed silica gel 218, it will continue to press inward, and then continue to be transmitted inward through the pressure-resistant tube 207. At this time, these external pressures will be transmitted to the position of the hexagonal force-balancing frame 206, and the hexagonal force-balancing frame 206 will counteract the external pressure to prevent these pressures from continuing to be transmitted inward;

[0056] When the compressive force reaches a certain level, it will continue to be transmitted inwards. At this time, the rear egg-shaped curved frame 209, the middle egg-shaped curved frame 210 and the front egg-shaped curved frame 211 inside the hexagonal force-equalizing frame 206 will bear the pressure, and the external pressure will be dispersed through the rear egg-shaped curved frame 209, the middle egg-shaped curved frame 210 and the front egg-shaped curved frame 211. Thus, through the structural characteristics of the rear egg-shaped curved frame 209, the middle egg-shaped curved frame 210 and the front egg-shaped curved frame 211, the pressure is evenly transmitted to the pressure-resistant filler 213, and then the pressure-resistant filler 213 is evenly transmitted to various places inside the cable, thereby completing the final unloading.

[0057] Furthermore, even if the rear egg-shaped curved frame 209, the middle egg-shaped curved frame 210 and the front egg-shaped curved frame 211 are deformed during the unloading process, they will open outwards at the first time instead of being squeezed and deformed inwards, thereby preventing the battery cell fixing sleeve 1 from being compressed during the unloading deformation, and further preventing these compressive forces from damaging the power transmission battery cell 203, thereby ensuring that the cable can resist the compressive force both in normal working processes and in extreme environments, preventing the power transmission battery cell 203 from being damaged due to compression and deformation during power transmission work, thereby ensuring the normal use of the cable, and when the cable is used in conjunction with large machinery, the cable is mostly laid flat on the ground, at this time It is inevitable that vehicles will pass through the site. At this time, a temporary speed bump will be laid on the outside of the cable to protect the cable. However, even with the speed bump, the cable will still be locally stressed. At this time, no matter where the pressure is transmitted from, one of the rear egg-shaped curved frame 209, the middle egg-shaped curved frame 210 and the front egg-shaped curved frame 211 will disperse the pressure, and multiple groups of rear egg-shaped curved frames 209, middle egg-shaped curved frames 210 and front egg-shaped curved frames 211 are provided to more stably support and protect the internal power transmission core 203, prevent cable damage, and further ensure the normal and stable operation of large machinery, thereby ensuring construction efficiency;

[0058] The rear egg-shaped curved frame 209, the middle egg-shaped curved frame 210 and the front egg-shaped curved frame 211 are all embedded in the inner side of the corresponding clamping groove 208, and the rear end of the hexagonal force-equalizing frame 206 has a rear fixing plate 212 to block and fix the rear egg-shaped curved frame 209, while the front egg-shaped curved frame 211 is fixed by fixing threaded holes 214, front fixing plates 215 and fixing screws 216 to prevent the rear egg-shaped curved frame 209, the middle egg-shaped curved frame 210 and the front egg-shaped curved frame 211 from being displaced during pressure relief work. At this time, it can be ensured that when subjected to pressure, the rear egg-shaped curved frame 209, the middle egg-shaped curved frame 210 and the front egg-shaped curved frame 211 will all be deformed outward from the middle in a uniform direction, thereby ensuring that the pressure can be evenly transmitted to the inside of the cable, further preventing the transmission core 203 from being deformed and damaged, and improving the stability of the cable in use;

[0059] Next, large machinery will inevitably move when in use, and it will inevitably drag the cable when the large machinery moves. During the cable dragging process, the ground will wear the wear-resistant rubber sleeve 220. During long-term use, the wear-resistant rubber sleeve 220 will be worn less and less. After years and months, the wear-resistant rubber sleeve 220 will be worn out. At this time, the inside of the cable will be exposed to the air. When it moves again, the polyethylene vacuum sleeve 217 will be worn. Because the polyethylene vacuum sleeve 217 is thin, the polyethylene vacuum sleeve 217 will be damaged immediately. At the same time as the polyethylene vacuum sleeve 217, the foamed silica gel 218 will immediately expand outward. At this time, the foamed silica gel 218 will expand and fill the damaged part of the wear-resistant rubber sleeve 220, so that the wear-resistant rubber sleeve 220 can continue to protect the inside of the cable, and can also prevent external humid air or moisture from corroding the cable, so that the cable does not need to be replaced or repaired during this project, so as to prevent the project progress from being delayed, and further ensure the project efficiency and reduce economic losses.

[0060] Finally, when the large machinery is in use, after one end of the cable is connected to the large machinery, the limit nut 306 can be loosened according to the installation position of the cable. At this time, the sliding sleeve 304 can be freely slid on the outside of the positioning sleeve 301 to adjust the position of the limit rotating plate 309 and the machinery. Then, the angle adjustment plate 311 is rotated through the rotating shaft 314 on the inner side of the angle adjustment groove 310, so that one of the angle adjustment plates 311 is attached to the surface of the large machinery. Then, the operator uses a screw to pass through the connecting screw hole 312 to fix the angle adjustment plate 311 on the surface of the large machinery, and the limit rotating plate 309 can be adjusted according to the size of the installation position. 09 is used to adjust the sliding position of the sliding sleeve 304 on the outside of the positioning sleeve 301. After the position of the sliding sleeve 304 is determined, the other angle adjustment plates 311 are fixed at the cable installation position of the large machinery. After the angle adjustment plates 311 are fixed, the limit nut 306 is re-tightened on the outside of the limit screw 305 to fix the position of the sliding sleeve 304. At this time, when people move large machinery, the high-voltage cable can be prevented from falling off due to excessive weight, thereby ensuring that the high-voltage cable can always provide stable power supply and preventing the interruption of engineering progress due to unstable power supply during the engineering process.

[0061] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention.
