Abstract
Disclosed is an air-supply lifesaving explosion-prevention safety helmet used under mine, belonging to the technical field of operation safety protection equipment. The utility model comprises a helmet body, an inductive controller, a cambered ring, an electromagnetic switch, an air storage tank, an electromagnetic valve and an air duct; wherein, the cambered ring is connected with the back part of the helmet body edge, the inductive controller is arranged on the helmet body and is respectively connected with the electromagnetic switch and the electromagnetic valve, the cambered ring is connected with the front part of the helmet body edge through the electromagnetic switch, one end of the air duct is connected with the cambered ring and the other end is connected with the air storage tank, and the electromagnetic valve is arranged on the air duct. Usually the cambered ring is fixed at the edge of the helmet body through the electromagnetic switch; when explosion accidents occur under mine, the electromagnetic switch is controlled to be on by the inductive controller, the air duct is driven by the cambered ring to fall off the edge of the helmet body, the user can keep the air duct in mouth immediately and the air or oxygen in the air storage tank is supplied to the user through the air duct. The utility model can win precious time for lifesaving, particularly applicable for safe production undermine.
Description
Technical field:
The utility model belongs to job safety protective articles technical field, is a kind of mine operation safety cap.
Background technology:
At present in the production process of mine, the well shooting accident happens occasionally, cause casualties, relevant department is by the investigation to death condition, find that a lot of miners are not dead at that time in the accident generation, cause death but accident takes place to suck toxic gas afterwards, and existing safety cap can only prevent that the weight that falls from injuring head by a crashing object, the injury that blast is produced can't prevent.
Summary of the invention:
The purpose of this utility model is that a kind of mine air feed lifesaving explosion-proof safety helmet that mine life saving in time automatically is provided to the personnel in the pit when blast takes place will be provided.
The scheme of the utility model technical solution problem comprises that mainly cap body, induction controller, loop, electromagnetic switch, air accumulator, magnetic valve and appendix constitute mine air feed lifesaving explosion-proof safety helmet, wherein loop is made by elastomeric material, be connected with the rear portion, edge of cap body, on the cap body induction controller is housed, induction controller connects electromagnetic switch and magnetic valve respectively, loop is connected with the edge of cap body is anterior by electromagnetic switch, one end of appendix is connected with loop, the other end connects air accumulator, and magnetic valve is contained on the appendix.Loop is fixed on the edge of cap body by electromagnetic switch at ordinary times, when the down-hole accident of blasting, induction controller receives information, the control electromagnetic switch is opened, and loop is because the elastic force effect drives the edge whereabouts of appendix from the cap body, its mouth of pipe moves near people's the oral area, the user can contain appendix at once, and induction controller control magnetic valve is opened, and air or oxygen process appendix is to user's air feed in the air accumulator.
Wherein, induction controller is made of sensor and signal processor, sensor can be pressure sensor or vibrating sensor, signal processor is a sensor adapter, can adopt integrated amplifier, sensor connects the signal processor input, and the signal processor input can connect pressure sensor and vibrating sensor simultaneously.
Electromagnetic switch is made of electromagnet, bull stick and axle, and bull stick is contained on the axle, and the iron of suction is arranged at the top of bull stick, it is corresponding with electromagnet to inhale iron, and hook is arranged at the bull stick bottom, loop on hook, signal processor output connection electromagnet.
When blast in the down-hole, signal processor is received the signal of telecommunication that sensor sends, and through the energising of signal processing controls electromagnet, electromagnetic actuation is inhaled iron, and bull stick rotates by axle, and loop breaks away from hook and falls.
The utility model the utility model can in time provide air or oxygen from the trend user after the generation well shooting, for the quality time is won in lifesaving, and dependable performance, simple in structure, be specially adapted to downhole safety production.
