Detailed description of the invention
As shown in Fig. 1,2,4, lifesaving safety strap used time in danger in swimming of the present utility model or water, is by can be that the waistband 1 on it and the automatic life-saving apparatus being arranged on waistband 1 outside face form around user's waist button.
Described waistband 1 is made by soft plastic band, fiber woven belt, canvas belt or stainless steel strip, this waistband 1 as ordinary straps, there is the snap close 11 of adjustable-tightness and under user water be that setting fastening is in loins.
Described automatic life-saving apparatus comprises that being installed in the lip-deep chamber 2(safety air bag 3 of laying safety air bag 3 of waistband 1 leaves in this chamber 2 in stacked mode), the gas tank 4 of compressed air suits (can be air, nitrogen or CO2 gas), the air-control device 5 that is arranged on the air valve on gas tank 4 tank mouths, gas piping 6 roads that air valve is connected with air bag 3 and inflates to air bag 3 according to the hydraulic pressure of waistband 1 water level depths, place and time length unlatching air valve.
Described chamber 2 is made by hard bakelite, plastic cement, aluminum alloy or stainless steel material, can establish two, four or six in the symmetry all around of waistband 1, and the utility model is preferably four, is separately positioned on the both sides, front and back of waistband 1.The length of chamber 2 volumes × wide × be deeply (6cm-8cm) × (4cm-6cm) × (1cm-3cm), chamber 2 also can be designed to ellipsoid, its upper surface or front end face are set to uncovered, the outlet of outwash that this is uncovered when being air bag 3 and inflating, chamber 2 inner wall smooths, open-mouth can be arranged to the round and smooth summary shape of closing up, and the air bag 3 that can avoid like this unaerated and compression to be stacked in chamber 2 skids off.
Air bag 3 can be arranged in chamber 2 by following two kinds of modes:
One, the root of air bag 3 is fixedly connected on waistband 1 or with chamber 2 inwalls and is fixed together through chamber 2 inwalls, its bottom relative position is provided with opening, opening is connected with the gas piping 6 penetrating by chamber 2 housing two wing passages or through hole, in the time opening air valve and inflate to air bag 3, gas passes through the first bottom by air bag 3 of gas piping 6 to the interior inflation of air bag 3, because chamber 2 is smooth inner wall, chamber 2 is released at the top of air bag 3 by the bottom air bag 3 swelling gradually, go out the air bag 3 that chamber 2 is filled with some gases pulls out the air bag 3 resting in chamber 2 outside chamber 2 under the effect of water buoyancy, thus, glutted air bag 3 is taken waistband 1 and is risen, upwards draw high by user, by rational design, can be when air bag 3 emerges, user's head holder is gone out to the water surface.
They are two years old, be provided with the piston that can move to the uncovered direction of chamber 2 under the promotion at gas in the bottom of chamber 2, the bottom of air bag 3 is fixed in the top of this piston, on the tank mouth of gas tank 4, be provided with two air valves, an air valve joins by road gas piping 6 roads and piston, another air valve is connected to air bag 3 by another road gas piping 6 roads, approaches on uncovered inwall and is provided with touch switch at chamber 2, and this switch and described air-control device 5 join.Pneumatics is received after actuation signal, first opening first air valve inflates to piston, on piston, move and the air bag 3 that compression is stacked in the unaerated in chamber 2 is released outside chamber 2, simultaneously, the piston rising touches described touch switch and opens second air valve, second air valve inflated to air bag 3, and in like manner, the air bag 3 of rising the most at last user's head holder goes out the water surface.
Described gas tank 4 adopts the withstand voltage steel cylinder of the pocket of selling on market in prior art.
Described gas piping 6 is rubber tube, on waistband 1 outside face, groove is set, and gas piping 6 can be embedded in groove, also can adopt alternate manner that gas piping 6 is fixed on the outside face of waistband 1.
Each section of gas piping 6 roads and four air bags 3 are serially connected, and also can adopt segmentation separately and the connection mode of air bag 3.While being connected in series, air bag 3 inflation has successively, and segmentation is while connecting separately, and air bag 3 inflations can be carried out simultaneously.
Described air bag 3 is made up of the low temperature resistant material of waterproof antiwear.Air bag 3 can be only individual layer, can be also inside and outside two-layer, and the material of outer optional wear-resisting good toughness is made, can select canvas, oxford or fiber cloth; Described internal layer can be made by PVC, PA, PE or rubber.
As shown in Fig. 3,5, the profile after described air bag 3 inflations is big up and small down, and it is flat face that itself and user's health are affixed side, and its outside side can be designed to the arcwall face of evagination.
Described air-control device 5 comprises direct supply, hydraulic pressure sensor, time timer and the control circuit according to the hydraulic pressure of waistband 1 water level depths, place and the automatic unlatching of time length control air valve.
Described control circuit comprises MCU, filter circuit, A/D convertor circuit, amplifying circuit and switch circuit, wherein, the input end of A/D convertor circuit joins with the mouth of filter circuit and time timer, input end and the hydraulic pressure sensor of filter circuit join, its mouth is connected to MCU, and MCU joins by amplifying circuit, switch circuit and described air valve.
The principle of work of this circuit is: when receiving that water level depth exceedes setting value and in the time that this water level time length also exceedes setting value, the i.e. analog signal to A/D convertor circuit stable output by filter circuit (this filter circuit mainly rises and gets rid of the error signal causing because of water pressure fluctuations), be converted to digital signal through A/D convertor circuit and pass to MCU, through relatively judging with hydraulic pressure and the time length setting value of MCU storage, started the control signal of air valve by MCU output, through amplifying circuit and switch circuit, described air valve is opened.
The utility model hydraulic pressure sensor used can be hydraulic pressure sensor conventional in prior art, preferred film pressure sensor.
It is the control apparatus 8 that the manual control knob 7 of independent operation is set on waistband 1 and regulates described setting value as further improvement of the utility model.
Manually control knob 7 directly joins with MCU, and it is in the time that person in distress regains consciousness, and by the button of my manually opened air-control device 5, this button can be button, can be also hand pulling type.
Control apparatus 8 joins with MCU, arrange thereon multiple relate to hydraulic pressure and under this hydraulic pressure the gear of time length, hydraulic pressure gear can water level depth represent, also can hydraulic pressure numeric representation.
Take for the convenience of the users some expeditious measuress, on waistband 1, be also provided with the reserve cartridge 9 of placing rope, survival knife, signaling bullet and/or torch.
In order to ensure the utility model in use, its control circuit is in normal condition, operating switch can be set on waistband 1 and meet the indicator lamp that water conducting shows, meanwhile, go back the indicator lamp of configurable general type, when lower water, can first open operating switch, indicator lamp is bright, illustrate that control circuit is working properly, when unexpected to guarantee to occur after lower water, control circuit can normally be worked.
