At the same time, the cable is easy to trip pedestrians, and pedestrians are also likely to drag the cable when walking, causing inconvenience to power maintenance. For this reason, we propose a cable laying protective device for power maintenance. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 The utility model provides a cable laying protection device for power maintenance, including a cover plate 1, a wiring groove 2 is provided at the bottom of the cover plate 1, a plurality of embedded grooves 3 are provided in an array at the bottom of the cover plate 1, a suction cup 4 is fixed on the inner wall of the embedded groove 3, a connecting groove 5 is provided on the inner wall of the embedded groove 3, the connecting groove 5 connects the embedded groove 3 with the wiring groove 2, a piston plate 6 is slidably connected to the inner wall of the connecting groove 5, and a hinge rod 7 is hinged at one end of the piston plate 6 away from the embedded groove 3, a linkage tube 8 is provided inside the wiring groove 2 through a displacement component, and the inner ends of the plurality of hinge rods 7 are hinged to the outer wall of the linkage tube 8.

[0021] In this embodiment, the displacement assembly includes a guide frame 9 fixed on the top surface of the wiring groove 2, and the side wall of the guide frame 9 is rotatably connected to a screw rod 10, and the circumferential outer wall of the screw rod 10 is threadedly connected to a nut 11, and the nut 11 is fixed to the side wall of the linkage tube 8. The guide frame 9 is a U-shaped structure, and the linkage tube 8 is slidably sleeved on the outside of the horizontal section of the guide frame 9. One end of the screw rod 10 extends to the outside of the wiring groove 2 and is fixed with an external hexagonal block. The external hexagonal block is twisted using a hand-held tool, so that when the screw rod 10 rotates, the nut 11 is threadedly connected to the screw rod 10, so that the nut 11 drives the linkage tube 8 to move along the outer wall of the horizontal section of the guide frame 9.

[0022] In this embodiment, the inner wall of the embedded groove 3 is a stacked cylindrical structure that is thin at the top and thick at the bottom. The lower end of the suction cup 4 extends to the outside of the embedded groove 3. After the suction cup 4 is adsorbed on the ground, the suction cup 4 is deformed and completely enters the embedded groove 3. At this time, the lower surface of the cover plate 1 touches the ground, preventing the suction cup 4 from being subjected to the pressure generated by the deadweight of the device, causing the suction cup 4 to deform and destroy the negative pressure cavity in the suction cup 4.

[0023] In this embodiment, a rubber head 15 is fixedly disposed at one end of the piston plate 6 close to the embedded groove 3 . The rubber head 15 abuts against the inner wall of the connecting groove 5 . The rubber head 15 enhances the sealing between the piston plate 6 and the connecting groove 5 .

[0024] In this embodiment, two protective plates 12 are hinged on the lower surface of the cover plate 1, and the side walls of the two protective plates 12 are provided with corresponding grooves 13 in an array. Several corresponding grooves 13 are movably mounted on the outside of several suction cups 4. When the device is in an idle state, the protective plates 12 prevent the suction cups 4 from contacting with the hard surface, thereby avoiding wear of the suction cups 4 and extending the service life of the suction cups 4.

[0025] In this embodiment, permanent magnets 14 are fixedly provided near the four corners of the lower surface of the cover plate 1. The four permanent magnets 14 are respectively against the upper surfaces of two protective plates 12. The protective plates 12 are made of iron. Through the magnetic adsorption of the permanent magnets 14 and the protective plates 12, the protective plates 12 are adsorbed and fixed on the lower surface of the cover plate 1, which is convenient for transporting the cable laying protection device.

[0026] Working principle and use process of the utility model: When the device is used, the cable is passed through the wiring groove 2, so that the cable extends from one side of the cover plate 1 to the other side of the cover plate 1, and the two protective plates 12 are folded to the position against the linkage pipe 8, and the cover plate 1 is placed on a smooth ground, so that the lower end of the suction cup 4 touches the ground, and the cover plate 1 is pressed down to deform the suction cup 4 until the suction cup 4 completely enters the embedded groove 3, so that the position of the inner wall of the suction cup 4 near the lower end is close to the ground, and the worker then uses a handheld tool to twist the outer hexagonal block to rotate the screw rod 10 Through the threaded connection between the nut 11 and the screw rod 10, the nut 11 drives the linkage tube 8 to move along the outer wall of the horizontal section of the guide frame 9. The linkage tube 8 drives several piston plates 6 to move along the inner wall of the connecting groove 5 toward the linkage tube 8 through several hinge rods 7, so that a negative pressure chamber is formed inside the connecting groove 5, thereby enhancing the adsorption force of the suction cup 4 on a smooth ground, and then enhancing the stability of the cover plate 1 placed on a smooth ground, so that the cover plate 1 can protect the cables in the wiring groove 2, prevent pedestrians from stepping on the cables, and shorten the service life of the cables.
