Embodiment 1

[0027] Such as figure 1 As shown, this embodiment includes a mixed gas cavity 1 and an ignition device 13 located in the mixed gas cavity 1 , wherein the human body ESD model 2 ignites the ignition device 13 , and the human body ESD model 2 is located in the control cabinet 11 . There is gas mixed with air in the mixed gas cavity 1, wherein the mixed gas cavity 1 communicates with the gas tank 7 through the electromagnetic valve 6, so that the gas tank 7 can be opened or closed by controlling the electromagnetic valve 6, In this way, the gas content in the mixed gas chamber 1 is controlled. In this embodiment, the human body ESD model 2 is a technique well known to those skilled in the art.

[0028] Such as image 3 As shown, the ignition device 13 includes a bracket 9 and an ignition electrode 10 fixed on the bracket 9. The ignition electrode 10 is connected to the high-voltage power supply 21 through the human body ESD model 2, and the high-voltage power supply 21 and the ...

Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is that in this embodiment, as figure 2 , image 3 , Figure 4 As shown, the mixed gas chamber 1 includes a table top 14, an experimental chamber cover 15 fixed on the table top 14, and a temperature sensor 5, wherein the temperature sensor 5 can be located at any place on the table top 14, either in the experimental chamber cover 15, or outside the protective cover 16, it is connected with the control cabinet 11 through the temperature measuring hole 22. The human body ESD model simulates the ignition device 13 inside the protective cover 16 . The experimental cavity cover 15 is set outside the protective cover 16, and an oxygen inlet hole 17 and a gas inlet / return hole 18 are opened in the protective cover 16, and the two ends of the experimental cavity cover 15 pass through side baffles 19 and gaskets 23. The pressure relief baffle 19 is fixedly arranged. For easier operation, the pressure relief baffle 19 c...

Embodiment 3

[0048] The difference between this embodiment and Embodiment 1 is that, in this embodiment, a protective net cover 20 can also be arranged on the periphery of the experimental cavity cover 15 to ensure the personal safety of the experimenters when the gas in the cavity explodes. Wherein, the protective mesh cover 20 is an arc-shaped stainless steel protective mesh cover with a thickness of 2mm.

[0049] Other technical characteristics are identical with embodiment 1, embodiment 2.

Abstract

The invention discloses a stimulated experiment system for gas detonation by human body electrostatic discharge, comprising a mixed gas cavity and an ignition device positioned in the mixed gas cavity, wherein the ignition device is controlled by a human body ESD (Electro-Static Discharge) model and carries out ignition; the mixed gas cavity is communicated with a gas tank through an electromagnetic valve and is connected with an oxygen concentration sensor, a gas concentration sensor and a temperature sensor, the human body ESD model, the ignition device, the oxygen concentration sensor, the gas concentration sensor and the temperature sensor are all connected with a computer control system, and the computer control system is connected with a display device. The system of the invention excites gas in the mixed gas cavity to carry out detonation through the human body ESD model and accurately provides values of gas concentration and oxygen concentration upon gas detonation through the infrared gas concentration sensor, an infrared analyzer, the oxygen concentration sensor and the like, thus both the technical support for human body electro-static safe protection in coal mine environment and the foundation for manufacturing electrostatic preventing working uniform of miner are offered.

Description

technical field [0001] The invention belongs to a simulation experiment system, and in particular relates to a simulation experiment system for finding the minimum discharge voltage of a human body, the breakdown field strength, the concentration of the gas most likely to detonate gas and their correlations. Background technique [0002] In recent years, coal mine accidents have occurred continuously, many of which are caused by the explosion of gas, and there are many reasons for the detonation of gas, and the electrostatic discharge of human body is an important factor that cannot be ignored. When coal miners work underground, the human body is in different states of motion, and the movements are fast and slow. Many tests have shown that when a worker fully dressed in mining uniforms makes sudden movements such as falling and undressing, the peak value of the electrostatic potential of the human body is the same as that of the same dress when doing slow movements.
