Description

Mine safe cap with face's air bag

Technical field

The utility model relates to a kind of Mine safe cap, specifically a kind of Mine safe cap with face's air bag.

Background technology

At present, miner in Mineral Engineering generally works in dark mine at below ground hundreds of rice, under the impact of crustal stress and dynamic pressure, roof fall or cave-in accident easily occur in down-hole, cause the down and out situation of miner to occur, thereby make miner's facial wound or die because being choked to death.And traditional Mine safe cap usually just plastics or metal cap body only can reduce that miner's excuse top ore drops and the injury that is subject to, function singleness, can not effectively address the above problem.

Summary of the invention

The problem existed for above-mentioned prior art; the utility model provides a kind of Mine safe cap with face's air bag; the injury that not only can reduce miner's excuse top ore to drop and be subject to; meet with bang when falling down when miner's head simultaneously; can also provide protection for miner's face; and for the miner provides breathing space, the situation generation of avoiding miner's facial wound or dying because being choked to death.

To achieve these goals, a kind of Mine safe cap with face's air bag of the utility model, comprise cap body, pressure sensor, ECU and air bag module, described pressure sensor is fixedly mounted on cap external surface middle part, described ECU is fixedly mounted on rear end in the cap body, and described air bag module is fixedly mounted on cap body Inner Front End; The signal output part of described pressure sensor is connected with the input of ECU, and the output of described ECU is connected with air bag module.

Air bag module comprises gas generator and air bag, and gas generator is connected with air bag.

The outer surface of sensor, ECU and air bag module is equipped with water proof and dust proof film or water proof and dust proof cover.

Also comprise the airbag actuation switch, described airbag actuation switch is located at the outside of cap body, and the airbag actuation switch is connected with ECU.

Also comprise acceleration transducer, described acceleration transducer is located on the cap body, and is connected with ECU.

With traditional Mine safe cap, compare, the utility model not only can reduce that miner's excuse top ore drops and the injury that is subject to, simultaneously by the cap body, pressure sensor being set, ECU and air bag module, the density of load be impacted by pressure sensor perception cap body, and will clash into signal and send ECU to, the signal of ECU receiving sensor is also judged whether to open air bag, when the ECU judgement is necessary to open air bag, send and open air bag signal, thereby by airbag-releasing, realized the protection to miner face, gap between air bag and miner face provides breathing space for the miner simultaneously, finally avoided meeting with bang when falling down when miner's head, facial wound or the situation of dying because being choked to death occur.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, the Mine safe cap of the utility model band face air bag, comprise cap body 1, pressure sensor 2, ECU 3 and air bag module 4, described pressure sensor 2 is fixedly mounted on cap body 1 outer surface middle part, described ECU 3 is fixedly mounted on the interior rear end of cap body 1, and described air bag module 4 is fixedly mounted on cap body 1 Inner Front End; The signal output part of described pressure sensor 2 is connected with the input of ECU 3, and the output of described ECU 3 is connected with air bag module 4.

Preferably, described air bag module 4 comprises gas generator 41 and air bag 42, and gas generator 41 is connected with air bag 42.

At first, the same with traditional Mine safe cap, cap body 1 can reduce that miner's excuse top ore drops and the injury that is subject to.Secondly, as shown in Figures 2 and 3, the density of load that pressure sensor 2 is impacted for receiving cap body 1, and output signal to ECU 3; After ECU 3 receives the signal of pressure sensor 2, judge whether immediately to be necessary to open air bag 42, unnecessarily open air bag 42 if judge, do not send the signal of opening air bag 42; Be necessary to open air bag 42 if judge, send open air bag 42 signal to air bag module 4; After gas generator 41 in air bag module 4 receives the signal of opening air bag 42, produce rapidly a large amount of gas and send air bag 42 to, thereby opening air bag 42, and then realizing the protection to miner face 5; Simultaneously between air bag 42 and miner face 5, can leave certain gap 6, can provide breathing space for the miner, finally avoid thumping when falling down when miner's head meets with, facial wound or the situation generation of dying because being choked to death.

Preferably, can be respectively equipped with at the outer surface of sensor 2, ECU 3 and air bag module 4 water proof and dust proof film or water proof and dust proof cover, compare water proof and dust proof film or water proof and dust proof cover are not set, more can guarantee after arranging that each workpiece avoids the interference of water, dirt, improve its accuracy, make it more can be suitable for subsurface environment simultaneously, further extended its service life.

As shown in Figure 4, as further improvement of the utility model, also can comprise airbag actuation switch 7, described airbag actuation switch 7 is located at the outside of cap body 1, and airbag actuation switch 7 is connected with ECU 3.When the miner falls down in the course of the work because of carelessness or tripped, the miner can press airbag actuation switch 7 voluntarily, ECU 3 sends the signal of opening air bag 42 after receiving enabling signal, thereby start air bag 42, avoid miner facial wound or situation of dying because being choked to death when falling down because of carelessness or being tripped to occur, further improved miner's personal safety.

As shown in Figure 5, as further improvement of the utility model, also can comprise acceleration transducer 8, described acceleration transducer 8 is located on cap body 1, and be connected with ECU 3, acceleration transducer 8 is the acceleration situation on all directions for detection of cap body 1, and ECU 3 receives detection signal, and judge whether to send the signal of opening air bag 42, and then control and whether start gas generator 41 and open air bag 42.When the miner falls down in the course of the work because of carelessness or tripped, acceleration transducer 8 can detect an acceleration to front lower place, meet the requirement of opening air bag 42, therefore ECU 3 can send a signal of opening air bag 42 to gas generator 41, thereby opened air bag 42, the situation that prevents facial wound when the miner falls down or trips or die because being choked to death occurs, and has further improved miner's personal safety.
