Description
Technical Field
The utility model relates to a gaseous detection device belongs to gaseous detection technical field.
Background
In the prior art, in places where monitoring personnel cannot enter, such as coal face goafs, areas beyond air return corners, tunnel high-lift areas, inactive coal chutes, areas beyond gob-side entry retaining seals and the like, in the domestic coal mine, a gas sampler and a beam tube are pre-embedded in advance, a handheld balloon or a gas sampler is used for sampling in a normal monitoring method, and a gas sample conveying bladder is conveyed to a ground monitoring room for gas analysis. The gas needs a certain time to be sampled and sent to the ground by utilizing the bladder, and the gas is easy to change when the time in the bladder is too long, so that the monitored gas is not accurate enough.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model lies in providing a gas detection device, and pre-buried gas sample thief and beam tube are inserted to the accessible intake pipe, realize improving the gaseous detection accuracy to the quick analysis of sampled gas.
Gaseous detection device include: a control box; the control panel is fixed in the control box; the sampling air chamber is fixed at the bottom of the control box; a gas sensor fixed in the sampling gas chamber; and a sampling pump fixed in the control box; the sampling pump air inlet end passes through the intake pipe and communicates with the air supply that awaits measuring, the sampling pump is given vent to anger the end and is passed through blast pipe and sampling air chamber intercommunication, be equipped with the exhaust hole on the sampling air chamber, gas sensor, sampling pump all are connected with the control panel through the wire.
PCB control panel or small-size PLC controller (like siemens LOGO) can be chooseed for use to the control panel, and the during operation passes through the intake pipe with the sampling pump inlet end and is connected with the air supply that awaits measuring, and control sampling pump work, the gas that awaits measuring gets into blast pipe and sampling air chamber in proper order through the sampling pump, is discharged by the exhaust hole after detecting through the gas sensor in the sampling air chamber.
Preferably, the intelligent temperature control device further comprises an alarm lamp, a temperature sensor, a power switch, a power supply interface and an antenna which are fixed on the control box. The alarm lamp, the temperature sensor and the power switch are all connected with the control panel through wires, and the antenna is in communication connection with the control panel.
Preferably, the control box further comprises a handle fixed on the top of the control box.
Is convenient for hanging and moving.
