Fixing device for a photodetector

Abstract

The invention provides a photodetector fixing device, which includes a placement frame, a pitch adjustment mechanism and a support mechanism, the placement frame can fix the photodetector, and the pitch adjustment mechanism can adjust the pitch angle of the placement frame. The support mechanism includes a support plate on which the pitch adjustment mechanism is installed, and the support mechanism can drive the pitch adjustment mechanism to rotate on the support plate. The advantage of the fixing device of the photodetector provided by the present invention is that: the photodetector is placed by the placement frame, the adjustment of the vertical viewing angle of the photodetector is realized by the pitch adjustment mechanism, and the adjustment of the horizontal viewing angle is realized by the support mechanism, thereby being able to adapt to large The demand for space and multi-angle detection. The automatic clamping and release of the photodetector is realized through the lateral movement of the movable clamping mechanism, and the disassembly is convenient.

Description

technical field [0001] The invention relates to the technical field of sensor installation equipment, in particular to a photodetector fixing device. Background technique [0002] The principle of a photodetector is that radiation causes a change in the conductivity of the irradiated material. Photodetectors are widely used in various fields of military and national economy. Photoelectric detectors can be used for long-distance monitoring of toxic gases. However, in the existing technology, toxic gas monitoring instruments such as photoelectric detectors are generally fixed on simple support frames during installation, and the installation and disassembly of poisonous monitoring instruments are troublesome and time-consuming. It is laborious, and the angle cannot be adjusted after installation, so the monitoring range is narrow. For example, the utility model patent with the publication number CN205484284U discloses a multifunctional harmful gas monitor. The harmful gas mo...

Photoelectric detectors can be used for long-distance monitoring of toxic gases. However, in the existing technology, toxic gas monitoring instruments such as photoelectric detectors are generally fixed on simple support frames during installation, and the installation and disassembly of poisonous monitoring instruments are troublesome and time-consuming. It is laborious, and the angle cannot be adjusted after installation, so the monitoring range is narrow

For example, the utility model patent with the publication number CN205484284U discloses a multifunctional harmful gas monitor. The harmful gas monitor is fixedly connected to the base through the charging base, and the base is connected to the bottom of the rack. The angle of the harmful gas monitor cannot be adjusted, thereby As a result, the monitoring range of the harmful gas monitor is narrow and the monitoring effect is not good

[0003] The utility model patent with the publication number CN212932547U discloses a toxic gas detector that is easy to view information. It hinges the gas detector with the housing, and at the same time sets a suction cup on the housing to facilitate the fixing of the entire detector. However, this The structure is mainly for the convenience of adjusting the direction of the gas detector so as to view the detection information of toxic gases. When this solution is used to adjust the angle of the detector, the angle adjustment range is limited, and only a small angle can be carried out in a pitch space. Adjustment, still unable to meet the needs of large-scale gas detection
