Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically to a cable protection device for power engineering. Background Technology

[0002] Electrical engineering refers to engineering projects related to the production, transmission, and distribution of electrical energy. In a broader sense, it also includes engineering projects that use electricity as a power source and energy source in various fields. The transmission and distribution of electrical energy is mainly achieved through high- and low-voltage AC power networks. During the construction of electrical engineering projects, electrical engineering cables need to be laid in the pipes below the cable wells to achieve the transmission of electrical energy.

[0003] During operation, power cables are sometimes subjected to external influences and friction with the ground, which can damage them over time and pose certain safety hazards. Therefore, this does not meet the current requirements, and we propose a power cable protection device. Utility Model Content

[0004] The purpose of this utility model is to provide a power engineering cable protection device to solve the problem mentioned in the background art that power engineering cables are sometimes affected by external factors and rub against the ground during operation, which will eventually damage the power engineering cables and pose certain safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power engineering cable protection device, comprising a base, a support seat fixedly connected to the upper end of the base, a sliding plate movably connected between the lower part of the support seat and the upper end of the base, two symmetrical fixing plates fixedly connected to both sides of the bottom end of the sliding plate and both sides of the upper end of the base, a roller rotatably connected between each symmetrical fixing plate, an arc groove being formed on the outer surface of each roller near the middle, a connecting block fixedly connected to one side of the base, a connecting groove corresponding to the connecting block being formed on the side of the base away from the connecting block, and the connecting block being inserted into the adjacent connecting groove.

[0006] Preferably, the slide plate is slidably connected to the inside of the support base, and the top of the slide plate is rotatably connected to a threaded rod via a pivot, with the threaded rod threaded through the top of the support base and extending to the outside of the top of the support base.

[0007] Preferably, symmetrical movable slots are provided on both the front and rear sides of the connecting slot and inside the base, and a limiting rod extending through and to the outside of the movable slot is movably connected inside the two movable slots.

[0008] Preferably, a limiting plate is fixedly connected to the outer surface of one end of the limiting rod inside the movable groove, and a spring is fixedly connected between one side of the limiting plate and one side of the inner wall of the movable groove, and the spring is wound around the outer surface of the limiting rod.

[0009] Preferably, symmetrical limiting grooves are provided on both the front and rear sides of the connecting block, and the limiting rod extends through one end of the movable groove into the interior of the connecting groove and is inserted into the corresponding limiting groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model involves passing one end of the cable between two rollers, then rotating the threaded rod so that the threaded rod passes through the top of the support base and rotates at the top of the slide plate. This pushes the slide plate to move the upper roller closer to the upper end of the cable. The arc groove on the outer surface of the roller protects and wraps the cable, preventing it from being damaged by friction when in contact with the ground. At the same time, the rolling contact of the roller makes it easy to pull the cable up.

[0012] 2. This utility model involves pulling the limiting rods at one end of the base, causing the limiting rods to compress the limiting plate and spring, and moving the other end of the limiting rod away from the connecting groove, retracting it into the interior of the movable groove. Then, the connecting block on one side of the other base is inserted into the connecting groove of the adjacent base. Afterward, the pulling of the limiting rod is released, causing the spring to release its elastic force, thereby pushing one end of the limiting rod through and extending into the interior of the connecting groove, and inserting it into the interior of the limiting groove, thus connecting and fixing the two bases together, which is convenient for connecting and supporting cables of different specifications according to their length.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 4 An embodiment of this utility model provides a power engineering cable protection device, including a base 1, a support seat 2 fixedly connected to the upper end of the base 1, a sliding plate 3 movably connected between the lower part of the support seat 2 and the upper end of the base 1, two symmetrical fixing plates 4 fixedly connected to the two sides of the bottom end of the sliding plate 3 and the two sides of the upper end of the base 1, a roller 5 rotatably connected between each symmetrical fixing plate 4, an arc groove 501 opened on the outer surface of each roller 5 near the middle, a connecting block 7 fixedly connected to one side of the base 1, a connecting groove 101 corresponding to the connecting block 7 opened on the side of the base 1 away from the connecting block 7, and the connecting block 7 is inserted into the adjacent connecting groove 101.

[0020] The slide plate 3 is slidably connected to the inside of the support base 2. The top of the slide plate 3 is rotatably connected to the threaded rod 6 via a pivot, and the threaded rod 6 has its top thread passing through the top of the support base 2 and extending to the outside of the top of the support base 2.

[0021] By passing one end of the cable between the upper and lower rollers 5, and then rotating the threaded rod 6, the threaded rod 6 passes through the top of the support base 2 and rotates to the top of the slide plate 3, thereby pushing the slide plate 3 to move the upper roller 5 closer to the upper end of the cable. The arc groove 501 on the outer surface of the roller 5 protects and wraps the cable, preventing the cable from contacting the ground and causing friction damage. At the same time, the rolling contact of the roller 5 makes it easy to pull the cable up.

[0022] Symmetrical movable slots 102 are provided on both the front and rear sides of the connecting slot 101 and inside the base 1. A limiting rod 8 extending through the movable slot 102 is movably connected inside the two movable slots 102. A limiting plate 9 is fixedly connected to the outer surface of one end of the limiting rod 8 inside the movable slot 102. A spring 10 is fixedly connected between one side of the limiting plate 9 and one side of the inner wall of the movable slot 102, and the spring 10 is wrapped around the outer surface of the limiting rod 8. Symmetrical limiting slots 701 are provided on both the front and rear sides of the connecting block 7. The limiting rod 8 extends through the outer side of the movable slot 102 into the interior of the connecting slot 101 and is inserted into the corresponding limiting slot 701.

[0023] By pulling the limiting rod 8 at one end of the base 1, the limiting rod 8 causes the limiting plate 9 to compress the spring 10, and causes the other end of the limiting rod 8 to move away from the connecting groove 101 and retract into the interior of the movable groove 102. Then, the connecting block 7 on one side of the other base 1 is inserted into the connecting groove 101 of the adjacent base 1. Then, the pulling of the limiting rod 8 is released, so that the spring 10 releases its elastic force, and then pushes one end of the limiting rod 8 through and into the interior of the connecting groove 101, and inserts it into the interior of the limiting groove 701, thereby connecting and fixing the two bases 1, which is convenient for connecting and supporting cables of different specifications according to their length.

[0024] When using the cable protection device for power engineering, one end of the cable is passed through the upper and lower rollers 5, and then the threaded rod 6 is rotated so that the threaded rod 6 passes through the top of the support base 2 and rotates to the top of the sliding plate 3. This pushes the sliding plate 3 to move the upper roller 5 closer to the upper end of the cable. The arc groove 501 on the outer surface of the roller 5 protects and wraps the cable, preventing the cable from being damaged by friction when in contact with the ground. At the same time, the rolling contact of the roller 5 makes it easy to pull the cable up.

[0025] Then, by pulling the limiting rod 8 at one end of the base 1, the limiting rod 8 causes the limiting plate 9 to compress the spring 10, and causes the other end of the limiting rod 8 to move away from the connecting groove 101 and retract back into the movable groove 102. Then, the connecting block 7 on one side of the other base 1 is inserted into the connecting groove 101 of the adjacent base 1. Then, the pulling of the limiting rod 8 is released, so that the spring 10 releases its elastic force, and then pushes one end of the limiting rod 8 through and into the interior of the connecting groove 101, and inserts it into the interior of the limiting groove 701, thereby connecting and fixing the two bases 1, which is convenient for connecting and supporting cables of different specifications according to their length.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
