Problems solved by technology

[0002] During the laying process of ground cables, special cable ducts such as glue-filled cement pipes are usually used as the installation pipeline space. Once the ground cables are installed, they will be used for a long time, and the underground topographical structure will change with time. During the change process, due to the vacancy inside the cable duct, the possibility of pressure deformation and fragmentation is extremely high, and the protection effect on the cable is reduced. The pipes in the section will shift, resulting in a large gap between the pipes; both of the above two situations will bury hidden dangers for the cable to be cut off

Embodiment Construction

[0013] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0014] Such as figure 1 with figure 2 As shown, an anti-digging early warning device for underground cables includes several warning ground piles 1, several layers of mesh-like protective structures 2 and warning devices 3, and the warning ground piles 1 include underground tip parts 1-1, fixing points The column part 1-2 of the network protection structure 2 and the pile body part 1-3 on the ground, each warning ground pile 1 is independent of each other, the pile body part on the ground is drawn with warning graphic symbols, and the tip part 1-1 underground is used For wedging into the ground, the pile body part 1-3 on the ground is used to draw yellow and black stripe warning signs to warn that there are cables here, and the middle column body part 1-2 is used to fix the net-like protective structure 2.

Abstract

The invention provides a damage preventive early warning device for an underground cable. The device comprises cautioning ground piles, layers of netted protective structures and a warning device, each cautioning ground pile comprises an underground tip part, a netted protective structure fixed cylinder part and an overground pile body part, the cautioning piles are independent from each other, and a cautioning graph symbol is drafted on the overground pile body part; each netted protective structure comprises a grid-shaped structure formed by plastic cement, metal wires are buried in the grid-shaped structure as reinforcing ribs, loop structures are arranged in corners of the netted protective structure, and the netted protective structure is fixed to the cylinder part via the loop structures; and the warning device comprises a smoke generator arranged on the netted protective structures. The multiple layers of netted protective structure improves the damage preventive resistance, ammonia water makes reaction with hydrogen chloride in the smoke generator to simulate smoke caused by fire when the cable is damaged, and an excavator is cautioned.

Description

technical field [0001] The invention relates to a cable protection device, in particular to an anti-digging early warning device for underground cables. Background technique [0002] During the laying process of ground cables, special cable ducts such as glue-filled cement pipes are usually used as the installation pipeline space. Once the ground cables are installed, they will be used for a long time, and the underground topographical structure will change with time. During the change process, due to the vacancy inside the cable duct, the possibility of pressure deformation and fragmentation is extremely high, and the protection effect on the cable is reduced. The pipes in the section will be displaced, resulting in a large gap between the pipes; the above two situations have buried hidden dangers for the digging of the cables. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004]...
