Handheld water leakage detection device based on overhead lines

Abstract

The invention discloses a handheld water leakage detection device based on overhead lines. The device is characterized by comprising a central control unit, a water leakage probe, a voltage comparator, a voltage follower and an AD converter, wherein the water leakage probe is connected to the input end of the voltage comparator; the output end of the voltage comparator is connected to the input end of the voltage follower; the output end of the voltage follower is connected to the input end of the AD converter; and the output end of the AD converter is connected to the input end of the centralcontrol unit. The device adopts the water leakage probe and a signal conversion circuit, so that extra work of manual observation is omitted; and furthermore, through the central processing unit of the device, water leakage conditions and position information input by workers can be automatically recorded in a memory, and manual recording is not needed, so that the working efficiency is greatly improved, and a defect that errors are easily caused by manual recording is overcome.

Description

technical field [0001] The invention relates to a hand-held water leakage detection device, which belongs to the technical field of detection devices. Background technique [0002] Catenary is a special form of transmission line erected along the railway line to supply power to electric locomotives. It is composed of contact suspension, supporting device, positioning device, pillar and foundation. Contact suspensions include contact wires, suspension strings, catenary cables, and connecting parts and insulators. The contact suspension is erected on the pillar through the supporting device, and its function is to transmit the electric energy obtained from the traction substation to the electric locomotive. The supporting device is used to support the contact suspension and transfer its load to the pillar or other structures. It varies according to the section where the catenary is located, the station and the large building. Support devices include wrist arms, horizontal ...

AI Technical Summary

Problems solved by technology

The staff should regularly check the appearance of the catenary, check whether there is any water leakage above the catenary, and count the leakage points above the positioning point, and the serious situation and location of the water leakage above the busbar. At present, the staff manually record these situations. Convenience and extra workload for work
