Description
Technical Field
The utility model relates to a gaseous detecting instrument technical field of laser.
Background
The laser absorption spectrum detector utilizes the characteristic that methane molecules absorb the specific wavelength strongly, namely, when laser beams pass through methane gas, the intensity of the laser is attenuated, and the attenuation of the laser intensity is in direct proportion to the concentration of the gas to be detected.
The length of a gas pipeline of a domestic first-line city is over ten kilometers, the average length of the gas pipeline is 200 meters, and the gas pipeline is a gas well and a gas well cover, all the gas pipeline wells are manually inspected, and an on-line monitoring means is urgently needed. The leakage frequency of the low-pressure court line network is still very high, so that the detection probability of the related valve well is higher; the valve well corresponding to the high-pressure pipeline has high leakage risk; the main monitoring objects of the valve well comprise: gas leakage, accumulated water, displacement and damage of a well cover.
In detecting gas concentrations, laser detection is typically used to determine the approximate location of a gas leak, such as in municipal gas valve well detection. The test of city gas pipe network and the maintenance of city gas pipe network are important parts for ensuring the safe application of city natural gas. The traditional inspection instrument adopts a thermocatalysis technology, and performs sample gas analysis in an air suction sampling mode and a point inspection mode. The semiconductor laser detection technology adopts a wire harness remote measurement inspection mode without sampling sample gas, the laser beam senses the current advanced laser gas detection technology, and non-contact measurement is adopted, so that remote measurement can be realized, and a leakage source can be quickly searched.
In the prior art, there are hand-held laser gas detectors, and there are several brands of equipment available on the market. However, hand-held laser gas detectors are independently powered devices that have no other purpose than laser gas detection. The existing semiconductor laser gas detection instrument in the market generally has the characteristics of large volume, heavy mass, slow reaction speed, low sensitivity and the like, and when the gas concentration is detected, if an urban gas valve well is used for detection, the instrument needs to be carried and patrolled and examined, and the specific position of a region with large gas concentration is accurately determined.
The utility model provides a small, the light and convenient laser gas detector that can fix with the cell-phone of hand-carrying of quality. The elastic clamp type laser gas detector for the mobile phone can be connected with the mobile phone through a power line for power supply, extra power supply is not needed, the power supply configuration cost is saved, the module technical parameters meet the use requirements, and the elastic clamp type laser gas detector is suitable for manual inspection and can be distributed to one hand of an inspection team. The elastic clamp type mobile phone holder is fixed on a mobile phone in an elastic clamp type manner, is convenient and quick to install, can be used in combination with functions of picture shooting, video recording and the like of the mobile phone, and can record the field situation in time.
