Problems solved by technology

Usually the power supply of the gas detector is DC24V DC power supply, the UPS power supply in the control room is used to supply power to the detector through the explosion-proof hose, but some field environmental equipment is relatively simple, there is no UPS power supply, only AC22V AC power supply, when powering the detector In order to convert AC220V to DC24V, a high-cost control box must be installed first.

Embodiment 1

[0012] A fixed gas detector, comprising an explosion-proof junction box, a detector, and an acousto-optic alarm; it is characterized in that: the detector is connected to an explosion-proof junction box through the junction box, and the detector is connected to the acousto-optic alarm through the acousto-optic diameter change The bottom of the detector is connected to the sensor; the explosion-proof junction box is provided with a cable introduction device.

Embodiment 2

[0014] The technical solution adopted in the present invention is: the fixed gas detector includes an explosion-proof junction box, a gas detector and an audible and visual alarm. Among them, the explosion-proof junction box is on the left side of the detector, the sound and light alarm is on the right side of the detector, the connection between the two ends of the equipment adopts explosion-proof variable diameter, and the explosion-proof sensor structure is designed under the detector. The lead-in device is installed on the left side of the explosion-proof junction box. The power supply cable is connected to the internal terminal of the explosion-proof junction box through the lead-in device. When the cable is connected, it can be connected to the AC220V power supply and can be connected to the DC24V power supply.

Abstract

The invention discloses a fixed gas detector. The fixed gas detector comprises an explosion-proof junction box, a detector and an audible and visual alarm, the detector is characterized in that the detector is connected with the explosion-proof junction box in a reducing manner through the junction box, and is connected with the audible and visual alarm in an audible and visual reducing manner; the bottom of the detector is connected with a sensor; and a cable leading-in device is arranged on the explosion-proof junction box. According to the technical scheme, the fixed gas detector comprisesthe explosion-proof junction box, the gas detector body and the audible and visual alarm. The explosion-proof junction box is arranged at the left side of the detector, the audible and visual alarm isarranged at the right side of the detector, the connection mode between equipment at two ends adopts explosion-proof reducing, and an explosion-proof sensor structure is designed below the detector.A lead-in device is arranged on the left side of the explosion-proof junction box, a power supply cable is connected with a terminal in the explosion-proof junction box through the lead-in device in awiring mode, and when the cable is connected, AC220V power can be connected, and DC24V power can be connected.

Description

technical field [0001] The invention relates to a fixed gas detector, in particular to a multifunctional fixed gas detector. Background technique [0002] At present, in the explosive gas detection environment, there are many types of gas detection equipment, and the application of fixed gas detectors is becoming more and more extensive. Usually the power supply of the gas detector is DC24V DC power supply, the UPS power supply in the control room is used to supply power to the detector through the explosion-proof hose, but some field environmental equipment is relatively simple, there is no UPS power supply, only AC22V AC power supply, when powering the detector , It is necessary to install a high-cost control box to convert AC220V into DC24V. Contents of the invention [0003] In order to overcome the high cost of the control box, the present invention provides a multifunctional fixed gas detector, which is characterized in that an explosion-proof junction box is instal...
