Structure used for realizing adjustable performance of light path in space

Abstract

The invention relates to the motor vehicle tail gas remote sensing equipment technology field and especially relates to a structure used for realizing adjustable performance of a light path in a space. The structure comprises a fixing bottom plate, a module fixing plate and a module adjusting plate. An adjustment slot is arranged in a middle portion of the fixing bottom plate, and an adjustment embossment which is cooperated with the adjustment slot is arranged at a bottom of the module fixing bottom plate. Two sides of the fixing bottom plate and the module fixing plate are provided with threaded holes. After upper and lower angles of the module fixing plate are adjusted, the module fixing plate passes through the threaded holes through a bolt so that the fixing bottom plate and the module fixing plate are connected. Adjustment holes are arranged on two sides of the module adjusting plate, and an adjustment bolt passes through an adjustment hole and is connected to the module fixing plate. The mechanism can be used to ensure that an ultraviolet telemetering gas analysis module and a tail gas laser telemetering gas analysis module do not affect each other when a light path is adjusted, and a single module can be individually adjusted in horizontal and vertical directions.

Description

technical field [0001] The invention relates to the technical field of remote sensing equipment, in particular to a structure that can realize an adjustable optical path in space. Background technique [0002] The vehicle exhaust ultraviolet remote measurement gas analysis module is an analysis module for online remote measurement of NO and HC emissions from motor vehicle exhaust on the road. It measures based on the principle of ultraviolet differential spectroscopy technology, and uses a unique optical technology platform to measure the NO and HC concentrations emitted by road vehicles in real time. During the measurement, the measurement module and the reflection module are installed on both sides of the measurement target. After adjusting the optical path, the light is emitted in parallel after the action of the parabolic reflector, and the outgoing light passes through the lane and is reflected back by the reflection module. [0003] When the motor vehicle exhaust lase...

Problems solved by technology

[0004] The original structure is to install two modules on the front panel of the equipment. Due to the heavy weight of the modules, the modules are in a cantilever state, which will cause vibration during transportation and handling, resulting in loosening of the modules and deflection of the optical path.

And when the device is subjected to external force, the device will produce a very small amount of deformation, which will also cause the optical path to deflect
