Embodiment Construction

[0026] The specific embodiment of the device of the present invention is described in detail below in conjunction with accompanying drawing:

[0027] Such as Figure 1-4 As shown, the device of the present invention includes an air filter 1, a semiconductor laser 2, a laser beam space correction lens 3, a group of beam space filter diaphragms 4, a detection chamber 5, a detection chamber support 6, a smoke scattering detector Device A, a laser power detector B, an extinction mechanism C, a reflector D, and a housing 7.

[0028] Wherein, the detection chamber support 6 is fixed as one with the detection chamber 5; the semiconductor laser 2 and the laser beam space correction lens 3 are screwed into one body, and the semiconductor laser 2 is fixed on the detection chamber support 6 by four screws up, down, left, and right, and can be passed through Four screws are screwed in tight to fine-tune the position of the semiconductor laser 2; the side of the detection chamber 5 close ...

Abstract

The present invention belongs to the field of fire detecting and warning technology. The smoke concentration detector includes air filter, semiconductor laser, laser beam space correcting lens, laser beam space filtering diaphragm, detecting chamber, detecting chamber rack, smoke scattering detector, laser power detector, extinction mechanism, reflector and casing. All the parts are installed inside the casing except the air filter inserted to the air inlet of the casing.

Description

technical field [0001] The invention belongs to the technical field of fire detection and alarm, in particular to a smoke concentration detection device. Background technique [0002] With the development of my country's economic construction, some special places that play a vital role in the national economy and social life (such as computing centers, graphic archives and information centers, post and telecommunications hubs, integrated circuit production workshops, nuclear power plants, large-scale modern scheduling control center, intelligent building control center, modern medical institutions, etc.) fire safety requirements are increasingly urgent. Due to the highly concentrated and long-term operation of various electrical equipment inside, there are many fire hazards. Once a fire occurs, it will cause great economic losses to the country and have a major impact on society. In view of the importance and particularity of these places, the problem of ultra-early fire det...
