Embodiment 1

[0020] A portable gas monitoring protective equipment, its structure diagram is as follows figure 1 , 2 As shown, including safety helmet shell 1; lining filter layer; 2; waterproof layer 3; 8; Ventilation hole 9; Visor 10; Respiratory mask 11; Soft belt and mask connection 12; Cotton surround 13; Portable gas monitor 14; Card slot 15;

[0021] Wherein: the use method of a portable gas monitoring protective equipment includes the following steps:

[0022] When the operator enters the well, wear a safety helmet, and wear the rubber hose 5 between the body and the clothes, so as to protect the hose 5 and not affect the operation. When entering the gas or carbon monoxide concentration dangerous hidden danger area, the portable gas monitor 14 on the safety helmet is opened. When the portable gas monitor 14 sends an alarm indication, it is enough to wear the breathing mask 11 on the safety helmet.

[0023] The working principle of the portable gas monitoring protective equipmen...

Abstract

The utility model discloses portable gas monitoring protective equipment, and belongs to the technical field of safety equipment. The protective equipment comprises a mining safety helmet and a portable gas monitor. The using method of the portable gas monitoring protective equipment comprises the following steps that: when a person is in a gas or carbon monoxide concentration dangerous area, the gas monitor on the safety helmet gives an alarm, and the person wears the mask until the mask covers the mouth and the nose; air flow enters a lining filter layer from the legs of the human body through a rubber hose and a silica gel air guide pipe so as to be used for breathing of the human body; as the density of gas and carbon monoxide is lower than that of air, the gas and carbon monoxide float on the upper layer of the air; when the concentration exceeds the standard, the rubber hose can conduct low-position gas and air with low carbon monoxide concentration to protect the safety of the human body; the concentration of harmful gas is further reduced through the filter layer filled with a nano porous material for filtering out the carbon monoxide and gas, so that the safety of the worker is ensured. The equipment has the advantages of reducing load in hands of the worker, facilitating operation activities and protecting the safety of the worker.

Description

technical field [0001] The invention belongs to the technical field of safety equipment, and in particular relates to a portable gas monitoring protection equipment. Background technique [0002] In the process of underground production, mine gas and carbon monoxide often exceed the limit. Although downhole ventilation will remove such toxic and harmful gases, carbon monoxide poisoning and gas overruns may occur to workers during underground production activities. At present, the staff monitor the underground gas concentration and carbon monoxide concentration mainly through hand-held detectors. Hand-held gas monitors mainly include JCB4 portable gas detector and CD-type portable parameter analyzer. Although the gas and CO gas can be well monitored, it needs to be hand-held, which brings inconvenience to the staff. Therefore, be necessary to invent a kind of usage is simple and easy, can be fixed on the portable downhole gas monitoring protective equipment that is conveni...
