Description

Technical Field

[0001] The utility model relates to a natural gas leakage detection device, in particular to an angle adjustment bracket and an electric vehicle laser telemetry device. Background Art

[0002] At present, the existing underground gas pipeline leakage detection equipment at home and abroad is classified into: ① handheld gas detector, ② handheld laser detector, ③ pump suction trolley detector, ④ pump suction patrol electric vehicle, ⑤ pump suction detection vehicle, ⑥ vehicle-mounted front laser detection vehicle system and ⑦ top laser telemetry vehicle system. Among them, the handheld gas detector needs to be manually held for patrol inspection, and the detection speed is very slow. The pump suction structure needs to suck the gas into the main unit, the detection speed is very slow, and it needs to walk above the gas pipeline network. The detection range is very small, and it must be no more than five meters above the buried gas pipeline to detect it. The top laser telemeter is installed on the top of the car. It can be rotated 360° up and down and left and right through the pan-tilt to detect the surrounding gas leakage. Because the density of natural gas is smaller than that of air, after leaking from the pipeline, the gas diffuses quickly. The higher the distance from the ground, the lower the concentration. During the gas detection process of the patrol vehicle, because the telemeter is installed on the roof pan-tilt too high from the ground, it is easy to miss the detection.

[0003] At present, there is also a detection device that places a laser detector on an electric vehicle for remote measurement, such as the Chinese invention patent with announcement number CN109340581B, which discloses a lateral blind detection scanning device for gas underground pipeline leakage, the device includes a laser detector, the laser detector includes a main control module, a laser detection module and an acoustic and light alarm module, the laser detection module and the acoustic and light alarm module are both connected to the main control module; the laser detection module is set at a height of 10 to 50 cm from the ground at the front end of the motor vehicle or electric vehicle through a bracket, and the angle between the laser emission direction of the laser detection module and the direction of travel of the motor vehicle or electric vehicle head is between 45 and 90°. Although this device overcomes the shortcomings of low detection efficiency, high cost, low accuracy and limited buried position of the gas pipeline leakage detection device in the prior art. However, the fixing device used to install the laser detection device is unstable, inconvenient to adjust, and has poor seismic resistance, which can easily lead to insensitive gas detection during the electric vehicle riding detection process.
