Laser methane sensor capable of conveniently judging methane source direction

Abstract

The invention discloses a laser methane sensor capable of conveniently judging a methane source direction. The laser methane sensor comprises a controller and a sensor, and further comprises a mounting plate, wherein the mounting plate is connected with a bottom plate through a vertical rotary assembly; the bottom plate is connected with a top plate through a horizontal rotary mechanism; a fixed plate is connected onto the top plate through a movable assembly; the sensor is arranged on the fixed plate; the vertical rotary assembly drives the bottom plate to vertically rotate relative to the mounting plate, so that vertical rotation of the sensor is realized, and content of methane on different vertical planes is conveniently detected, and therefore, content of methane in different verticaldirections is detected. The laser methane sensor is high in sensitivity, and can judge sources of methane gas directions in different vertical planes.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a laser methane sensor which is convenient for judging the source direction of methane. Background technique [0002] The methane sensor is a device that converts the methane concentration variable in the air into an output signal with a certain corresponding relationship. Continuous monitoring of methane concentration in areas, mechanical and electrical caverns, etc. As we all know, the methane sensors currently on the market can only be used to detect the methane content in the current environment, and cannot be used to judge the source of methane. It is difficult to find the place where methane is leaking, and cannot effectively solve the problem. Searching through traditional methods is labor-intensive. Work efficiency is low. The application publication number is: CN106769868A, and the application publication date is: May 31, 2017. The patent discloses a laser ...

The application publication number is: CN106769868A, and the application publication date is: May 31, 2017. The patent discloses a laser methane sensor that is convenient for judging the direction of the source of methane. Multiple laser methane sensors detect the content of methane in multiple directions and then judge The direction of the source of methane, the shortcoming of this patent is that it can only detect the methane content in different directions in one plane. When the leaking direction of methane is not in the plane, the judgment is not accurate; on the other hand, multiple laser methane sensors increase cost
