Embodiment 1

[0032] In view of the above problems, this embodiment provides an air detection device for a mine confined space, such as figure 1 As shown, it includes an air graduated cylinder 1, a pump suction detector 2 and a negative pressure pump 3; the air graduated cylinder 1 is used to collect the air in a closed space; such as figure 2 , 3 As shown, the air measuring cylinder 1 includes a cylinder body 4, and the front and rear ports of the cylinder body 4 are respectively matched with an ordinary electric control valve 6 and a timing electric control valve 5, and the ordinary electric control valve 6 and the timing electric control valve 5 The front and rear ends are blocked, so that a cylindrical sealed cavity is formed inside the cylinder body 4; such as Figure 5 As shown, the inner cavity of the cylinder body 4 is matched with a conjoined piston 41 . The conjoined piston 41 seals the cylindrical inner cavity into a front debugging cavity 42 and a rear sample cavity 43 , and t...

Embodiment 2

[0041] The difference between Embodiment 2 and Embodiment 1 is that the controller of the electronic control system 7 is provided with a connecting wire 73 connected to the execution system of the controller.

[0042] like Image 6 As shown, the controller of the electronic control system 7 is provided with a connecting wire 73 connected to the execution system of the controller, and the other end of the connecting wire 73 is provided with a connecting plug 74, and the connecting plug 74 is used for connecting with the control system of the detector, Specifically: the detector 2 is provided with a signal transmission socket, the signal transmission socket is connected with the control system of the detector 2, the connecting plug 74 can be matched with the signal transmission socket, and the detector 2 is working, that is, the detector When the suction pump of 2 is turned on, the control system of the detector 2 will send a detection signal to the controller of the electronic ...

Embodiment 3

[0044] The difference between Example 3 and Example 2 is that, as figure 2 As shown, the bottom of the circumferential side wall of the cylinder is provided with a placement seat 8, and the placement seat 8 is used to support the cylinder 4 of the air graduated cylinder. turn.

Abstract

The invention discloses mining air detection equipment for a closed space. The mining air detection equipment comprises an air measuring cylinder, a pumping type detector and a negative pressure pump, the air measuring cylinder comprises a cylinder body, and a common electric control valve and a timing electric control valve are installed at the front end and the rear end of the cylinder body respectively in a matched mode. A conjoined piston is sleeved in an inner cavity of the cylinder body in a matched manner, the cylindrical inner cavity is hermetically divided into a front debugging cavity and a rear sample cavity, and the conjoined piston can slide towards one side with lower air pressure along the wall of the inner cavity of the cylinder body; the device is unique in structure, convenient to operate and accurate and reliable in detection result.

Description

technical field [0001] The invention belongs to the technical field of air detection, and in particular relates to an air detection device for a mine closed space. Background technique [0002] Confined space, an industrial safety term, refers to a sealed and closed environment, such as manholes, tunnels and pump rooms. Because the access to the site is restricted, and the confined space is usually full of indoor air pollution; from the perspective of fire protection, risk assessment is carried out, and the confined space has huge dangers, including easy to cause deadly phenomena such as flashback and flash combustion. In mines, there are many confined spaces. Before working in the confined space, training and assessment are usually required, and the air quality in the confined space needs to be tested at the same time. [0003] If the air quality in the enclosed space is unstable, it needs to be left to stand for a period of time to stabilize, and then the air detection de...
