Embodiment Construction

[0040] Several specific embodiments of the gas detector for gas drainage pipelines of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0041] The first embodiment of the gas detector for the gas drainage pipeline of the present invention is as figure 1 As shown, the gas detector for gas drainage pipeline of the present invention is a detector that is inserted into the gas pipeline 300 from the pipeline insertion hole 301 on the pipe wall of the gas pipeline to perform detection during use. The detector includes a gas detection probe The rod, the gas detection probe includes a hollow rod body 3 , a part of the hollow rod body 3 near one end is an insertion section, and the insertion section is inserted into the gas channel 300 when in use.

[0042] The hollow rod body 3 can directly adopt a pipe body structure, and the air inlet and outlet pipes 4 arranged side by side are installed inside. The insertion section of the ho...

Abstract

The invention relates to a gas detector for a gas drainage pipeline and a gas detection probe rod thereof. Specifically, the detector comprises a hollow rod body, an installation shell, a gas detection sensor and a gauge outfit , wherein the hollow rod body is internally provided with an air inlet pipe and an air outlet pipe, the installation shell is connected to the end, away from the insertionsection, of the hollow rod body, a detection cavity is formed in the installation shell, and an inner cavity of the detection cavity forms a detection cavity; a part of the gas detection sensor is located in the detection cavity so as to detect gas parameters in the detection cavity; the gas inlet pipe and the gas outlet pipe are respectively communicated with the detection cavity to form a detection passage for gas to enter from the gas inlet, pass through the detection cavity and be discharged from the gas outlet; and the gauge outfit is used for detecting signals of various sensors arrangedon the hollow feeler lever. The detector is advantaged in that airflow in the gas channel of the detector can quickly enter and fill the detection cavity through the gas inlet pipe, and the gas detection sensor can quickly detect gas parameters, consistent with the gas channel, in the detection cavity.

Description

technical field [0001] The invention relates to a gas detector for a gas drainage pipeline and a gas detection probe rod thereof. Background technique [0002] As the safety requirements of coal mining are getting higher and higher, gas detection is generally carried out in coal mining at present. Existing instruments for gas detection are various, among which, the pipeline insertion type detector is particularly convenient. For example, the Chinese Utility Model Patent Specification whose authorized announcement number is CN203572515U discloses a plug-in gas parameter measuring instrument. Only the sensors installed in the room can accurately detect the gas parameters in the gas pipeline, resulting in a slow response speed of the measuring instrument. Contents of the invention [0003] The object of the present invention is to provide a gas detector for a gas drainage pipeline to solve the problem of slow response speed of existing detectors. At the same time, the pres...
