Technical Field
[0001] The utility model relates to the technical field of gas safety detection equipment, in particular to a portable laser gas leakage detection equipment. Background Art
[0002] In China, gas is used in all aspects of life. Gas pipelines are spread underground throughout the city and in various buildings. Gas pipeline leaks will cause great safety hazards, so it is necessary to regularly detect gas leaks.
[0003] Currently, there are handheld laser instruments that can detect methane gas in fuel gas and determine whether there is a gas leak by detecting the methane content.
[0004] However, the lasers emitted by laser instruments are all linear, which means that laser detectors can only detect positions that can be reached in a straight line. When the path to be detected is a right angle, there will be blind spots that cannot be detected, and the detection operation is not convenient. Figure 4 As shown in the schematic diagram of underground pipeline gas leakage, the laser emitted by the existing handheld laser instrument can detect the gas at point A, but when the leakage source is at point A or point B, if the leakage is small, the methane gas cannot flow to point A, making it impossible to determine whether there is a gas leakage at point A.
[0005] Therefore, a portable laser gas leak detection device is proposed. Utility Model Content
[0006] The purpose of the utility model is to provide a portable laser gas leak detection device. By setting up sleeve one, sleeve two, and sleeve three as sliding connections, when performing detection, sleeve two and sleeve three can be pulled out according to height requirements, and the laser head can be pulled to a suitable height to adapt to the height of the detection position and avoid detection blind spots, so as to solve the problems raised in the above-mentioned background technology.

A display device is provided on the sleeve one.
[0009] Preferably, the display device includes: a ring, a display screen, a cross bar, and a fixed frame. The ring is fixedly sleeved on one side wall of the sleeve, and two cross bars are fixedly connected to the two side walls of the ring. The fixed frame is rotatably installed at one end of the two cross bars, and the display screen is detachably installed in the fixed frame. Damping is provided at the rotational connection between the display screen and the two cross bars.

[0011] Preferably, the locking assembly includes a limiting ring, a screw, and a slider; the limiting ring is fixedly connected to the side wall of the sleeve one, the slider is slidably installed inside the limiting ring and extends into the interior of the sleeve one, one end of the screw is rotatably connected to the slider, and the side wall of the screw is threadedly connected to the inner wall of the limiting ring.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. Set up casing one, casing two, and casing three-phase sliding connection, and fix the laser head on casing three.
