Abstract
The utility model relates to an earthquake-proof gas-filled protecting bag, which comprises a safety air bag (1) and is characterized in that a case body (3) coated with a sodium azide mixture (2) is arranged in the safety air bag (1), a motor (4) is also arranged in the case body (3), the output end of the motor (4) is positioned in the sodium azide mixture (2), an iron pipe (10) is connected with an end electrode of a power supply for the motor (4) through a conducting wire, and the motor (4) is operated through a series of devices when an earthquake happens to cause the sodium azide to react and generate gases so as to inflate the safety air bag (1). The earthquake-proof gas-filled protecting bag can have certain supporting effect when a roof falls down in the earthquake, thereby increasing the escaping chances for people and prolonging the escaping time.
Description
Technical field
The protective device that the utility model relates to a kind of earthquake when taking place.
Background technology
The generation meeting of earthquake brings great life and property loss to people, does not at present also have a kind of facility can be used to reduce the infringement of earthquake to people in people's the house, or the escape time when increasing people's earthquake and taking place.
Summary of the invention
The purpose of this utility model then is at present above-mentioned the deficiencies in the prior art, and providing a kind of can increase the escape antidetonation gas-filled protective bag of chance of people when earthquake.
The technical solution of the utility model is as follows:
A kind of antidetonation gas-filled protective bag; include air bag; it is characterized in that in air bag, being equipped with the casing that is surrounded by the sodium azide mixture; also be provided with motor in the casing; the output of motor is positioned at the sodium azide mixture; iron pipe connects a termination electrode of motor power by lead; the other end electrode of motor power is connected to and is positioned on the conducting block of iron pipe below; one end and the support of iron pipe are hinged; its other end is held by magnet; magnet is fixed on the bracing frame; below the middle part that is provided with iron pipe below the iron pipe, be provided with electromagnet; electromagnet is connected respectively on metal covering and the back taper contact by lead, and metal covering is installed on the pointer and is positioned at the back taper cavity of back taper contact, and the lower end of pointer is connected to balancing weight after passing the back taper contact.
Wherein, described metal covering is circular, and pointer vertically is positioned at the circle centre position of metal covering, and the iron pipe place of described electromagnet top also is provided with iron block.
The beneficial effects of the utility model are:
Can earthquake take place to play certain supporting role when the roof falls, thereby increase people's escape chance, prolong escape time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, sodium azide mixture 2 and motor 4 are housed in the casing 3 of the present utility model, the runner integral body of motor 4 and output axle head thereof is positioned over sodium azide mixture 2 inside.On the control circuit of motor 4, be provided with the control power supply, use for motor 4.The positive and negative iron pipe 10 and the conducting block 14 of being wired to extremely respectively of motor 4 power supplys, conducting block 14 is for to be made by conductive materials such as copper, aluminium, iron.One end and the support 11 of iron pipe 10 are hinged, its other end is held by magnet 16, magnet 16 is fixed on the bracing frame 12, below the middle part that is provided with iron pipe 10 below the iron pipe 10, be provided with electromagnet 13, electromagnet 13 is connected respectively on metal covering 5 and the back taper contact 6 by lead, metal covering 5 is installed on the pointer 7 and is positioned at the back taper cavity of back taper contact 6, and the lower end of pointer 7 is connected to balancing weight 8 after passing back taper contact 6.Above-mentioned metal covering 5 is circular, and it is positioned at the back taper cavity of back taper contact 6, and pointer 7 vertically is threaded onto the circle centre position of metal covering 5, and the lower end of pointer 7 is connected to balancing weight 8 after passing back taper contact 6.Casing 3 of the present utility model, back taper contact 6 and pointer 7 and balancing weight 8 all can be arranged on air bag 1 inside or only casing 3 be located in the air bag 1, and other each parts are arranged on air bag 1 outside.Air bag 1 is compressive state when earthquake does not take place, it is fixed on the base 9, and base 9 fixes on the ground.
The sodium azide in the casing 3 does not react in the air bag 1 at ordinary times, when strenuous vibration takes place when, because the effect of pointer 7 lower end balancing weights 8, make pointer 7 shake, thereby driving metal covering 5 shakes, when earthquake intensity is very big, metal covering 5 can touch on the inner conical surface of conical contact 6, because the inner conical surface of conical contact 6 also is a conductor, and it is the same all by lead connection motor 4 with metal covering 5, so after metal covering 5 is run into conical contact 6 inner conical surfaces, connect the circuit of electromagnet 13, electromagnet 13 produces magnetic force, attracts iron block 15 and iron pipe 10, touches conducting block 14 after the magnetic force that the right-hand member of iron pipe 10 overcomes magnet 16 falls, connect the control circuit of motor 4, motor 4 runnings.Because this moment, the right-hand member of iron pipe 10 left magnet 16 1 segment distances, the attraction of magnet 16 no longer can make iron pipe 10 overcome on himself gravity and carry, thereby the circuit of motor 4 can keep connected state, continuous running.Sodium azide mixture in the magnet casing 3 is subjected to can reacting behind the bump of motor 4 outputs and decomposites nitrogen, and the nitrogen that reaction decomposes goes out can be oppressed the sodium azide mixture again, thereby produces chain reaction, further makes sodium azide mixed decomposition gas.The characteristic that can the short time after utilizing sodium azide to be impacted produce a large amount of gases make air bag 1 the short time by the gas inflation, its volume is increased is original hundreds of times to form protective bag.This usefulness utility model can play the effect that replaces load bearing wall, collapses at load bearing wall and can play the effect of support when ceiling falls, and the room can not collapsed moment, for people increase the escape chance and prolong escape time.Air bag 1 in the utility model should be near four of load bearing wall local placements, and its chief of effect that can on average share power like this when ceiling falls prevents that protective bag from breaking owing to being subjected to excessive power.The utility model can be provided with metal covering 5 size and or the weight size of the balancing weight 8 earthquake magnitude lowest limit of coming control device to start, protective bag starts the situation of inflation less than the antidetonation rank in house to prevent earthquake grade.
Other undeclared part that the utility model relates to is same as the prior art.
