Field detection device of handheld explosion-proof infrared and ultraviolet flame detector

Abstract

The invention discloses a field detection device of a handheld explosion-proof infrared and ultraviolet flame detector. The field detection device comprises a shell; a piece of infrared glass and a light filter are sequentially superposed at the front end in the shell; an ultraviolet, laser and broad spectrum light source device is arranged at the rear part of the light filter; a reflector is arranged in back of the light source device; a control module connected with the light source device is arranged at the rear part of the reflector; a power supply device is arranged at the rear part of the control module; and the power supply device is connected with the control module through a lead and a switch. A broad spectrum lamp, an ultraviolet lamp, a parabolic reflector, the light filter, aninfrared glass window, a rechargeable battery, the control module and the like are combined to form the whole field detection device which can emit infrared and ultraviolet spectrums of certain frequency. The device can be used as a flame simulator and applied in the technical field of detection of fire fighting equipment, particularly applied to debugging and detection after field installation of an infrared flame detector, an ultraviolet flame detector and an infrared and ultraviolet composite flame detector.

Description

technical field [0001] The invention relates to a detection device for fire-fighting equipment, in particular to a field detection device for a hand-held explosion-proof red-ultraviolet flame detector. Background technique [0002] Red and ultraviolet flame detectors are very sensitive to hydrocarbons and carbon-containing compounds produced by fire combustion, and can be sensitively detected in the early stage of fire, so they are gradually and widely used in large-scale civil places with wide range and large span and petrochemical industry, etc. Inflammable and explosive high-risk industrial sites. In accordance with the National Fire Protection Facilities Testing Technical Regulations and Fire Engineering Acceptance Specifications, flame detectors need to be debugged and tested after installation. Among them, there are detailed regulations on the detection of red and ultraviolet flame detectors: for the detection of flame detectors, it is required to be within the detect...

Problems solved by technology

The Chinese patent application number is 20081001132.1, and the title is "On-site detection equipment for hand-held infrared flame detectors". In the patent article, the on-site detection equipment for infrared flame detectors is described. The wavelength is 830-950nm, and it cannot emit the infrared spectrum that can be detected by the infrared flame detector at all. In the specific implementation, RFIR55 is used. The energy emitted by this type of infrared light source is very weak. Whether it can meet the actual requirements of detection The distance is not mentioned in the patent, and at the same time, the problem of on-site detection of ultraviolet flame detectors is not solved

[0004] Chinese patent: ZL200620025307, titled "Portable Flame Detector Test Device", the method of generating red and ultraviolet light described is to use combustible gas, but whether the combustible gas can be fully burned is not mentioned, how to ensure that the combustible gas will not leak? It is mentioned that how to deal with the toxic gas produced after the combustible gas is burned is not mentioned, and how to inflate after the combustible gas is exhausted is not mentioned

This method is very dangerous in operation, and it is also very difficult to implement.
