Embodiment 1

[0045] An intelligent diffuse oxygen supply system for the face of a plateau tunnel, including an oxygen generation module, a control module, a storage module, and an oxygen supply module for the face of the tunnel;

[0046] The oxygen generation module is connected to the control module through the oxygen delivery pipe 1, and the control module and the oxygen storage module are connected through the oxygen delivery pipe 1;

[0047] The pressure sensor inside the oxygen storage module is connected to the intelligent control unit B inside the control module through the RS232 connection line 2, and the oxygen flow through the flow valve B is controlled by the intelligent control unit B;

[0048] The control module and the storage module deliver oxygen to the oxygen distribution panel 4 through the oxygen delivery hose 3, and release oxygen to the tunnel face 7 through the oxygen distribution panel 4;

[0049] The tunnel face 7 is equipped with an oxygen monitor 6, and the data m...

Embodiment 2

[0052] The oxygen storage module of this embodiment is installed near the face 7 of the tunnel, and is used to purify the oxygen in the air, and is connected to the flow valve A and the flow valve B of the control module through the oxygen delivery pipe 1, and the flow valve A and the flow valve B are respectively The oxygen distribution panel 4 and the oxygen storage unit of the oxygen storage module are connected through the oxygen delivery pipe 1 and the oxygen hose 3;

[0053] In this embodiment, the internal pressure monitoring unit of the oxygen storage module can monitor the oxygen pressure inside the oxygen storage unit in real time, and connect to the intelligent control unit B in the control module through the RS232 connection line. When the oxygen pressure is close to the limit storage capacity of the oxygen storage unit When the oxygen pressure is high, the intelligent control unit B intelligently adjusts the opening of the flow valve B, thereby controlling the amou...

Abstract

The invention relates to the technical field of oxygen generation and oxygen supply, in particular to an intelligent oxygen supply system for a tunnel face in a plateau region. The intelligent oxygen supply system comprises an oxygen generation module, a control module, an oxygen storage module and a tunnel face oxygen supply module, wherein the oxygen generation module is installed nearby the tunnel face and used for purifying oxygen in air; the control module is used for controlling the amount of oxygen flowing into the tunnel face and the oxygen storage module; the oxygen storage module is used for storing the oxygen purified by the oxygen generation module and supplying oxygen to the tunnel face; and the tunnel face oxygen supply module is used for releasing oxygen, monitoring the oxygen content of the tunnel face, controlling the amount of oxygen flowing into the tunnel face from the oxygen generation module and controlling the amount of oxygen flowing into the tunnel face from the oxygen storage module.

Description

technical field [0001] The invention relates to the technical field of oxygen production and oxygen supply, in particular to an intelligent oxygen supply system for tunnel faces in plateau areas. Background technique [0002] The face is an important part of tunnel excavation. Oxygen consumption is serious due to blasting and equipment, and the amount of construction dust is large. The decrease in oxygen content and oxygen partial pressure in the face is more obvious. Aiming at the problem of hypoxia on the face of the face, individual oxygen supply and oxygen bar car oxygen supply have been widely used. In fact, the capacity of the oxygen cylinder is small, and the continuous oxygen supply capacity is poor. If a larger oxygen cylinder is used, it will increase the burden on the operators, which will affect the construction and operation. On the other hand, the oxygen bar car has more restrictions on construction workers, and it is extremely inconvenient to use nasal suctio...
