Embodiment approach

[0044] Further, see figure 1 As shown, a method of using the device for detecting gas distribution characteristics in a confined space in a preferred embodiment is shown. Taking the measurement of oxygen distribution in a confined space as an example, the method of use is described below:

[0045] Si: Open the first measuring hole 41, the second measuring hole 42, the third measuring hole 43, the fourth measuring hole 44 and the fifth measuring hole 45 and introduce a certain amount of carbon dioxide gas, then cover the screw plug and let it stand for a while ;

[0046] Sii: open the gas measuring instrument 31, let it stand for a period of time in fresh air, open the top cover 11, fix the gas measuring instrument 31 on the fixing clip 32, close the top cover 11, and operate the remote control motor 34 to make the gas measuring instrument 31 and the fixing clip 32 move on the slide rail 33;

[0047] Siii: Refer to the scale 12 on the cylinder 1, use a certain interval as the...

Abstract

The invention discloses a device for detecting the gas distribution characteristics of a limited space, and relates to the technical field of limited space gas distribution detection. The device comprises a cylinder body and gas measuring equipment. The upper port of the cylinder body is provided with a top cover, the cylinder body is provided with a scale, the top cover is provided with a circular operation hole, and a plurality of measurement holes are equidistantly distributed in the side wall of the cylinder body in the vertical direction. The gas measuring equipment comprises a gas measuring instrument, a fixing clamp, a sliding rail, a remote control motor, a spool and a nylon wire, the sliding rail is arranged in the cylinder body, the gas measuring instrument is installed on the fixing clamp, the fixing clamp is slidably connected to the sliding rail, the remote control motor is installed on the top cover, the spool is installed on a motor shaft of the remote control motor, andthe two ends of the nylon wire are connected with the wire spool and the fixing clamp respectively. The device is low in manufacturing cost, is not affected by factors such as time, places and equipment, can enable students to have visual understanding of the gas distribution characteristics of a limited space, improves the training efficiency of the students, has three measurement modes, and canbe suitable for different gas measurement instruments.

Description

technical field [0001] The invention relates to the technical field of detecting gas distribution in a confined space, in particular to a device for detecting gas distribution characteristics in a confined space. Background technique [0002] Different gases have different characteristics. Many safety regulations regulate the oxygen content in confined spaces. People have a certain understanding of the danger of hypoxia, but there is still insufficient understanding of the distribution of gases in confined spaces. It is a rapid detection system for gas concentration in different parts of the space. Due to the lack of detection devices for the concentration of different gases in different parts of the confined space, the research on the safety of the confined space is greatly restricted. Contents of the invention [0003] In view of the above-mentioned problems, the purpose of the present invention is to provide a device for detecting gas distribution characteristics in co...
