Abstract

The utility model provides a high-altitude falling protecting air bag which comprise an acceleration sensor, an air bag body, a gas generator, a power supply, a switch and a single-chip microcomputer. The high-altitude falling protecting air bag has the advantages that the air bag is developed on the basis of the principles of parachutes and the ultrahigh mechanical performance of safety air bags, the air bag is simple, light, high in safety performance, the air bag can be inflated instantly and opened when a person falls from high altitude, the descending posture of the falling person can be adjusted, and the falling person can be well protected.

Description

Falling from high altitude protection air bag
Technical field
The utility model relates to a kind of protective device, and particularly a kind of falling from high altitude protection air bag, belongs to safety protection field.
Background technology
In recent years, the working environment of building trade constantly changes, manual labor is heavy, the unfavorable factor of various bursts jeopardizes the personal safety of job site personnel always, there is " three major injuries " (high falling, cave in, object hits) in building industry in accident, incidence is the highest, danger is high fall accident greatly, and this is perplexing the safety in production of building industry always.
9 o'clock every mornings, be that maximum time occurs accident 6 o'clock to 8 o'clock evening to ten one points, entangles its reason and be mainly this time period in relieving, and people's awareness of safety is indifferent.
Labor Day, 11 National Day, New Year's Day, the Spring Festival etc. are that accident occur is maximum time periods around festivals or holidays, have a lot of trade unions to visit friends and relatives during festivals or holidays, return in the surrounding time of building site and have carelessness, have loosened inwardly awareness of safety.
The black spot that the hazardous locations such as the dismounting of facing limit and vertical transportation machinery equipment of the buildings such as balcony, stairs port, reserved opening, elevator, maintenance, installation, maintenance are high falling.
People is subject to high speed impact power from falling from high altitude to be made organ-tissue suffer to a certain degree to destroy to cause damage, and severe patient is died instantly.Therefore, the main task of reduction building industry casualty accident is to avoid and reduce the generation of falling from high altitude accident.Although more existing protectors on market, most inconveniences that use, barrier propterty neither be absolutely, and particularly high-altitude builder cannot finely use especially.Although various places have been strengthened measure and prevented and treated dynamics from the aspect such as rules and regulations, safety management, the hidden danger of falling from high altitude accident, never thoroughly eradicates.
Summary of the invention
The purpose of this utility model is to provide falling from high altitude protection air bag.
The utility model solves the technical scheme that its technical problem adopts: falling from high altitude protection air bag is by acceleration transducer, air bag, gas generator, power supply, switch and single-chip microcomputer composition, it is characterized in that: air bag is connected with gas generator, gas generator is connected with single-chip microcomputer, single-chip microcomputer is also connected with power supply with acceleration transducer, power supply is controlled by switch, power supply provides voltage for single-chip microcomputer, acceleration transducer to external world information is made a response, signal is passed to single-chip microcomputer, single-chip microcomputer sends control signal, make gas generator produce gas, air bag expands, protection personal security.
Gas generator is connected to the bottom of air bag.Power supply, gas generator and acceleration transducer are directly connected with single-chip microcomputer.Power supply is controlled by external switch.Air bag is the high performance material that internal layer scribbles polychlorobutadiene, and after launching, there are certain thickness and small radian the end, and the oblique angle air bag of the outstanding certain length of surrounding structure in the form of slot after inflation, can be in the safety of multiple orientation protection human bodies.。
The beneficial effects of the utility model are: this device is that the mechanical performance based on parachute principle and air bag superelevation is developed, with it may be worn on, can user during from falling from high altitude moment inflatable open air bag, bladder shape design can help to change landing posture, increase resistance, air bag plays good protective action to the person of falling, and this device can use separately, also can use together with other protectors.
Accompanying drawing explanation
Fig. 1 is falling from high altitude protection airbag structure schematic diagram.
Fig. 2 is the airbag deployment figure of falling from high altitude protection air bag.
Fig. 3 is the air bag cross-sectional view of falling from high altitude protection air bag.
The specific embodiment
Below in conjunction with accompanying drawing, concrete structure of the present utility model is described further.
In Fig. 1,2,3,1-acceleration transducer, 2-air bag, 3-gas generator, 4-power supply, 5-switch, 6-single-chip microcomputer.
Acceleration transducer 1, gas generator 3, power supply 4 are directly connected with single-chip microcomputer 6.Gas generator 3 is connected in air bag 2, for air bag 2 produces the needed gas that expands.Power supply 4 provides electric energy for single-chip microcomputer 6, is controlled by switch 5.
The output of acceleration transducer 1 connects the input of single-chip microcomputer 6, and the output of single-chip microcomputer 6 connects gas generator 3.Acceleration transducer 1 is experienced acceleration, and this signal is passed to single-chip microcomputer 6, and single-chip microcomputer 6 sends control signal lights a fire gas generator 3, and now, the sodium azide that gas generator is 3 li can react generation nitrogen and inflate to air bag 2.Gas replenishment process is exceedingly fast, between 60ms, similar with safe automobile air bag 2 gas replenishment processes about 30ms.Air bag 2 adopts high performance material to make, and internal layer scribbles polychlorobutadiene, in order to sealing gas.
After air bag 2 launches, certain thickness and small radian are arranged at bottom, the oblique angle of the outstanding certain length of surrounding.2 ends of air bag, are designed to there is individual air layer with ground on the one hand, can increase buffering, can avoid on the other hand in gas replenishment process, people being impacted.Gas generator is near air bag 2 bottoms, and the moment that coordinates air bag 2 shape designs (being greater than top near foot oblique angle) can make people be rotated up, avoids people to face down and land.
While use, air bag 2 is folded into bag.There is a small amount of steam vent at the back of air bag 2, and the air bag 2 after inflation has certain thickness.When people lands while being pressed on air bag 2, can be from steam vent exhaust after air bag 2 pressurizeds.
When people is from that time of falling from high altitude, acceleration transducer 1 is experienced acceleration of gravity, and this signal is passed to single-chip microcomputer 6.Single-chip microcomputer 6 sends control signal to gas generator 1, the reaction inflation of sodium azide moment.Fall in process, air bag 2 helps the person of falling to slow down.After born, the person of falling lies on air bag 2, and air bag 2 is discharged nitrogen, prevents that the person of falling is hurt.
Work high above the ground is generally towards structures operation, seldom face down and land, the implementation mode that people couches can make device performance maximum effect, due to the oblique angle design of air bag 2 surroundings, can after touching the end, oblique angle make people lie in 2 ends of air bag, and make as far as possible people's body land, increase cross-sectional area, increase air drag, reduce the speed of landing, prevent that people is injured.
The utility model is from the mechanical performance of parachute principle and air bag superelevation; develop falling from high altitude protection air bag; that this air bag has advantages of is simple and easy, light, security performance is high; not only can the person of falling during from falling from high altitude moment inflatable open air bag; and can adjust the person's of falling landing posture, the person of falling is played a very good protection.
