Abstract

The utility model provides an automatic air pump in water, which is composed of a floating body, an air source and an automatic air pump. The utility model is characterized in that the floating body is connected with a worm wheel and a worm; the worm wheel passes through a swing arm, a connecting rod and a mobile push bar; the inflation course can be accomplished transitorily by that a positioning and triggering slice can toggle the automatic air pump automatically after the push bar is unhooked with the positioning and triggering slice. The utility model has the advantages of stable technical performance, safe utilization and short inflation time, etc., and the working environment can not be influenced by moisture.

Description

Automatic air pump in water

The utility model relates to a kind of aquatic life-saving equipment, is specially adapted to meet the automatic gas filed aquatic life-saving equipment of water.

Existing aquatic life-saving equipment after operation at sea personnel or occupant fall into water accidentally, is finished gas replenishment process automatically, and personnel are held out the water surface.But weak point is to need to be equipped with a kind of small-sized gas generator, needs to deposit the solid chemical material of some again, and solid chemical material requires the certain drying of maintenance, is not suitable for the working environment of device; And solid presses to producing gas from the beginning chemical reaction, and charges into air bag and all need the regular hour process, guarantee to meet 3 seconds with interior finish gas filed sea rescue standard be do not allow facile.Another exempts from pull-type automatic inflatable lifejacket, and its structure is with a paper string spring to be tied, and is configured on the life jacket.When drowning, because paper string dissolves, trip spring, spring promote striker and puncture gas storage device to airbag aeration.This device has the following disadvantages: the various devices that use on the ship, and in general, working environment humidity is higher, the paper string moisture-sensitive, it is tied up power and descends the generation misoperation; If the paper string anti-soak properties are good, will prolong the molten disconnected time of back of falling into water again, be difficult to guarantee snap action.

The utility model provides a kind of reliable, safe instantaneous aerated lifesaving device for overcoming above the deficiencies in the prior art.

The utility model mainly is made up of buoyancy aid, co gas storage cylinder and self-filler, especially the connection structure between buoyancy aid and the self-filler is improved.Promptly connect a worm gear, worm mechanism at buoyancy aid, worm gear moves a lever by swing arm, connecting rod again, and lever hooks certain position percussion sheet, controls self-filler with location moving of sheet of percussion.When the man overboard, rotate by buoyancy aid pulling worm screw, and then make the worm gear rotation, worm gear breaks off relations location percussion sheet by the moving lever of shipper pole on swing arm, the connecting rod, and control mechanism promotes self-filler and puts on the air, and the lifesaving appliance inflation produces buoyancy.

The utility model compared with prior art has instantaneous automatic inflation, and advantage such as safe and reliable.

The utility model is described in further detail below in conjunction with accompanying drawing: after aquatic work personnel or occupant fall into water accidentally, the buoyancy aid of wearing in the life jacket shown in Figure 1 22 is represented with the moving snail thick stick 24 of rope band by buoyancy of water such as Fig. 2, worm gear 23 is rotated, in Fig. 4, worm gear 23 drive swing arms 20 make on the connecting rod 19 and move, catch bar 21 breaks off relations with location percussion sheet 18, and angle square spacer 13 is in the tension action of spring 14.Round end Xiao 2 among Fig. 5 is subjected to the application force of spring 16 and springs down, so the hook plate 3 among Fig. 6, anti-plate 7, fagging 1 are under the effect of spring 4, unclamp pressure to steel ball 10, steel ball 10 breaks away from the locked groove of push rod 8, push rod 8 is under the effect of spring 9, promote lever 6 and drive the blowout disk that strikers 5 puncture air bottles 18, so the gas of being stored fills the air inlet capsule rapidly, above-mentioned all action was all finished in 1.8 seconds.Among Fig. 4, linking between catch bar 21 and location percussion sheet 18 has safety rope 15, is wound with heating wire 12 on safety rope 15.When operation at sea personnel or occupant fall into water accidentally, probe C among Fig. 7, the conducting of D two ends, give faint signal of BG1 base stage, trigger silicon control through amplifying, instantaneous (0.1 second) of silicon control conducting, heating wire produces high temperature by big electric current, heating wire 12 is on the safety rope 15 that tightly is made around nylon material, safety rope 15 is subjected to high temperature and disconnects, since the pulling force of spring 14, the same generation as a series of actions after above-mentioned catch bar 21 and the location percussion sheet 18 ' unhook.Like this with catch bar 21 and safety rope 15 common lock in place percussion sheets 18 ', the two has one to break off relations promptly to produce and move, to guarantee reliability of the present utility model.

Claims

1, a kind of chance water self-filler, be made up of buoyancy aid, co gas storage cylinder and self-filler, it is characterized in that buoyancy aid connects a worm gear, worm screw, worm gear moves catch bar by swing arm, connecting rod, promote pike pole and connect location percussion sheet, location percussion sheet is stirred self-filler.

2, gas filled device according to claim 1 is characterized in that a location percussion sheet and an angle square spacer apical grafting, and the angle square spacer is depressed the cup head pin of a band spring, and cup head pin props up a hook plate of self-filler.
