Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable protection mechanism. Background Art

[0002] In modern power systems, cables are the key medium for electric energy transmission. Their safe and efficient operation is crucial to ensuring the stability of urban power supply systems. With the acceleration of urbanization, the application scope of cables continues to expand, and cable laying technology is also constantly improving. Cable laying is a key link in the cable construction process. It involves unrolling the cable from the cable roll and laying it along a predetermined path through human or mechanical power. This process is crucial to ensure that electric energy can be delivered to its destination accurately and quickly.

[0003] However, in the actual cable laying process, the interaction between the cable and the surrounding environment is an issue that requires special attention. During the laying process, the cable will inevitably encounter various corners. If these corners are not properly handled, they will pose a threat to the safe operation of the cable. Specifically, if the cable is not equipped with an appropriate protective structure at the bend, the cable may come into direct contact and friction with the corner part of the metal bridge during movement. This direct contact and friction will not only increase the difficulty and resistance of cable laying, but may also cause damage to the cable sheath.

[0004] The cable sheath is an important component of the cable. It not only protects the internal wires, but also prevents the external environment from corroding and damaging the internal wires of the cable. The cable sheath is usually made of materials such as polyethylene and has certain insulation and corrosion resistance. However, if the cable rubs against the metal structure for a long time, especially in a humid or corrosive environment, the cable sheath may wear, peel or corrode, which will affect the insulation and corrosion resistance of the cable and shorten the service life of the cable.

[0005] In addition, once the cable sheath is damaged, it may cause more serious safety problems. Once the insulation layer of the cable is destroyed, the internal wires may be exposed, increasing the risk of ground short circuit. Ground short circuit is a serious accident in the power system. It may cause abnormal increase in current, causing fire, equipment damage and even casualties. Therefore, the protection of the cable sheath is extremely important for preventing cable accidents.

[0006] In order to solve the corner problem encountered during the laying of cables, the current traditional method is to wrap old clothes or other soft materials at the corners to reduce the direct contact and friction between the cables and the metal bridge. Although this method can reduce the friction resistance and the risk of cable sheath damage to a certain extent, it can only be used as a temporary response measure and cannot fundamentally solve the problem. Therefore, a cable protection mechanism is needed to solve the above problem. Utility Model Content

[0043] The working principle of the above embodiment is:

[0044] When the cable is laid under the outer wall environment, the angles of the No. 1 mounting plate 1 and the No. 2 mounting plate 2 are adjusted according to the angles of the turning corners encountered during the cable laying, and the No. 1 mounting plate 1 and the No. 2 mounting plate 2 are respectively installed on the outer wall by bolts. During the cable laying process, the cable is placed between the grooves on the opposite sides of the No. 1 cam 5063 and the No. 2 cam 5083, and then the handle 5022 is held and rotated, and the worm wheel 5024 meshed on the worm 5023 is driven to rotate under the rotation support of the bearing, and then the threaded sleeve 503 is driven to rotate under the rotation support of the bearing, and the push rod 5024 of the threaded sleeve 503 rotating inside the threaded sleeve 503 is driven to rotate. Under the action of force, the threaded rod 5051 is driven to move stably on the inner side of the threaded sleeve 503, and the thrust generated during the movement and the sliding connection cooperation between the adjusting moving block 5071 and the sliding rod 5073 stably drive the No. 1 concave support block 5061 to move, and clamp the cable between the opposite sides of the No. 1 concave wheel 5063 and the No. 2 concave wheel 5083. When the cable is pulled, the cable will drive the No. 1 concave wheel 5063 and the No. 2 concave wheel 5083 to rotate. The No. 1 concave wheel 5063 and the No. 2 concave wheel 5083 can guide the cable and prevent the cable from being damaged by friction with the turning corner, thereby protecting the cable.

[0045] Compared with the prior art: the cable protection mechanism, through the mutual cooperation between the No. 2 mounting plate 2, the connecting block 3, the groove 4 and the adjustable protection mechanism 500 on the No. 1 mounting plate 1, can simplify the cable laying process at the corners, reduce manual operations, improve construction efficiency, provide an additional layer of protection for the cable, and effectively reduce the risk of damage to the cable due to friction, extrusion or accidental impact during the laying process, thereby achieving effective layout of the cables at the corners and avoiding damage to the cables due to excessive bending, which not only extends the service life of the cables, but also reduces the maintenance costs caused by cable failures. At the same time, it can adapt to cables of different diameters and materials, as well as bending requirements of different angles, which not only ensures the safety of the cables, but also improves construction efficiency, optimizes the cable layout, and has good adaptability and easy maintenance. The problem that the existing cable protection mechanism cannot effectively reduce the direct contact and friction between the cable and the metal structure, and lacks the ability to adapt to cables of different diameters and materials and bending requirements of different angles is solved.
