Multifunctional measuring tool for electric power pipeline

Abstract

The invention discloses a multifunctional measuring tool for an electric power pipeline, which comprises a soft rubber column, wherein a measuring head is arranged at one end of the soft rubber column, the other end of the soft rubber column is connected with a display, a stretching and folding mechanism is installed between the measuring head and the soft rubber column. According to the invention, a straight pipe and a bent pipe are measured through a cylindrical head, a reducing sleeve and a pusher, the application range is wide, and the functions are wider. Meanwhile, the multifunctional measuring tool not only can perform a measurement operation, but also can perform a position correcting operation, so that the equipment can be propelled at a bent part, and the situation that the measuring head is clamped at the bent part is avoided. During specific implementation, once the measuring head moves to the bent part, the cylindrical head can slightly deflect so as to enable the measuring head to normally pass through the bent part. If the bent deformation part blocks the measuring head at the moment and the measuring head is in an inclined state, gas can be introduced into an arc-shaped cavity, so that the pusher pushes a piston head to slide, and the position of the measuring head is corrected.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of power pipes, and in particular to a multifunctional measuring tool for power pipes. Background technique [0002] The power pipe is a product made of PE (modified polyethylene) for hot dipping or epoxy resin for internal and external coating, and has excellent corrosion resistance. At the same time, the coating itself has good electrical insulation and will not cause electrical corrosion. Low water absorption, high mechanical strength, small friction coefficient, can achieve the purpose of long-term use. It can also effectively prevent the damage of plant roots and soil environmental stress. [0003] At present, during the burying process of power pipelines with large diameters, if they are subjected to a large impact (such as the pressure of a large number of stones), the outer wall will appear concave and deformed. Once the deformed pipeline is eroded by rain for a long time, it ...

Problems solved by technology

[0005] For this reason, the embodiment of the present invention provides a multi-functional measuring tool for power pipelines to solve the problem that in the prior art, due to the relatively single function and the relatively weak structural strength of the curved part, once it is impacted, multiple deformations will easily occur. When the device passes through, it is very susceptible to the influence of large deformation, resulting in the problem of jamming
