Air supply pipe joint leakage detection alarm device

Abstract

The invention discloses an air supply pipe joint leakage detection alarm device. The air supply pipe joint leakage detection alarm device comprises a sealing capsule, a piezoelectric plate, collecting rings and an alarm, and the sealing capsule wraps an air supply pipe joint; the piezoelectric plate is arranged on the lining of the sealing capsule; the collecting rings are arranged at the two ends of the piezoelectric plate; and the alarm is arranged on the outer side of the sealing capsule and is electrically connected with the collector rings. Air leakage of the air supply pipe joint is completely eradicated; leakage of an air supply pipe system in the running process of a vehicle is found in time, and alarm information is transmitted to the vehicle for centralized display; and compared with a traditional leakage checking method, environmental influence is avoided, the working efficiency is improved, the labor cost is reduced, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to an alarm device, in particular to a leak detection and alarm device for air supply pipe joints. Background technique [0002] The braking system of railway vehicles uses compressed air as the power source, and there are a large number of pipe joints in the braking device; the leakage of the brake piping system causes vehicle failures from time to time, which affects driving safety. There are many pipe joints, which have a certain degree of concealment; the traditional vehicle air supply system leak detection only relies on the air meter to detect leakage; the leakage point is checked by manpower segmented listening and smearing soapy water, which has the following defects: when the vehicle is running, The leakage of each joint under the car cannot be monitored in real time; the alarm is not timely, and the leakage problem cannot be found in time by inspectors checking the air meter from time to time; the information is not comp...

Problems solved by technology

[0002] The braking system of railway vehicles uses compressed air as the power source, and there are a large number of pipe joints in the braking device; the leakage of the brake piping system causes vehicle failures from time to time, which affects driving safety. There are many pipe joints, which have a certain degree of concealment; the traditional vehicle air supply system leak detection only relies on the air meter to detect leakage; the leakage point is checked by manpower segmented listening and smearing soapy water, which has the following defects: when the vehicle is running, The leakage of each joint under the car cannot be monitored in real time; the alarm is not timely, and the leakage problem cannot be found in time by inspectors checking the air meter from time to time; the information is not comprehensive, and the location of the fault point cannot be accurately judged; the traditional troubleshooting method is time-consuming and laborious. Labor intensity is high, and defects such as being greatly affected by the environment cause difficulties in troubleshooting, waste a lot of time, and affect vehicle operation

[0004] In summary, there is an urgent need for an air supply pipe joint leak detection and alarm device to overcome the problems in the prior art that the alarm is not timely, the information is not comprehensive, and the investigation is time-consuming and laborious.
