Abstract
The utility model relates to the technical field of underwater salvage equipment, in particular to a self-help underwater breathing apparatus provided with a floating ball. Compared with the prior art, the self-help underwater breathing apparatus comprises a breathing pipe, wherein the floating ball is fixed at the upper end of the breathing pipe; an air inlet end of the breathing pipe is covered with a waterproof cap; the other end of the breathing pipe is connected with an air inlet one-way valve and an air outlet one-way valve; the air outlet one-way valve is connected with an air outlet pipe; and a shrinkable air outlet balloon is arranged at the tail end of the air outlet pipe. The floating ball can ensure that the air inlet end of the breathing pipe is always positioned above water, and can also provide the function of a life buoy to a diver when the diver is in danger, so that the diver can be kept above water; and the self-help underwater breathing apparatus has the advantages of simple structure, safety in use, low manufacture cost and the like.
Description
Technical field
The present invention relates to rescue apparatus technical field under water, particularly a kind of saved oneself rebreather that has ball float.
Background technology
Swimming or during under-water operation in some superficial water, the general diving outfit that does not need to carry specialty, a lot of people directly adopt a kind of water pipe or bamboo bar to lead to the water surface to keep breathing, adopt this mode, and breather pipe is easy to be flooded in the entry, cause water inlet in the breather pipe, the user can not breathe, simultaneously, and when facing a danger as the scuba diver, this water pipe or bamboo bar not only can not provide an effectively relief, but also may bring some unnecessary troubles to the scuba diver.
Summary of the invention
Be to solve existing defective of snorkel and problem in the prior art, provide a kind of simple in structure and have a saved oneself rebreather of ball float.
The technical scheme that the present invention is adopted for its technical matters of solution is: the rebreather of saving oneself of the present invention comprises a breather pipe, a ball float is fixed in the breather pipe upper end, inlet end place at breather pipe is buckled with a tarpaulin, connecting a breather check valve and outgassing nonreturn valve at the breather pipe other end, outgassing nonreturn valve is connecting a freeing pipe, and the freeing pipe end is provided with a contractile balloon of giving vent to anger.
The invention has the beneficial effects as follows: compared with prior art, the rebreather of saving oneself of the present invention is provided with the ball float of certain buoyancy, ball float not only can keep the inlet end of breather pipe to be on the water surface all the time, and when the scuba diver faces a danger, the effect of buoy quoit can also be provided to the scuba diver, the scuba diver can be remained on the water surface, have advantages such as simple in structure, safe in utilization and low cost of manufacture.
Description of drawings
Below in conjunction with the drawings and specific embodiments the rebreather of saving oneself of the present invention is described further.
Fig. 1 is the structural representation of the rebreather of saving oneself of the present invention.
The specific embodiment
As shown in Figure 1, the rebreather of saving oneself of the present invention comprises a breather pipe 1, a ball float 2 is fixed in breather pipe 1 upper end, the buoyancy of ball float 2 is enough big, the upper end of breather pipe 1 is remained on the water surface, sink under water, cause breather pipe 1 water inlet and be unlikely to breather pipe 1, ball float 2 also serves as the role of a buoy quoit simultaneously, and enough buoyancy emerges for the scuba diver.Be buckled with a tarpaulin 3 at the inlet end place of breather pipe 2, tarpaulin 3 can prevent that the water wave and the water droplet of playing on the water surface from flowing in the breather pipe 2 by actv., connecting a breather check valve 4 and outgassing nonreturn valve 5 at breather pipe 1 other end, breather check valve 4 is breathed tube 6 with 5 outer connections of outgassing nonreturn valve, breathing tube 6 adopts soft material to make, have certain contractibility and elasticity, outgassing nonreturn valve 5 is connecting a freeing pipe 7, and freeing pipe 7 ends are provided with a contractile balloon 8 of giving vent to anger.
As shown in Figure 1, in actual use, the scuba diver fills in the breathing tube 6 of breather pipe 1 end in the nostril, the contractibility and the elasticity of breathing tube 6 make scuba diver nostril and extraneous sealing, the breathing in nostril can only be undertaken by breathing tube 6, when the besoin de respirer air inlet, gas enters from breather pipe 2, enter in the nostril through behind the breather check valve 4 then, breathe for the scuba diver, when the scuba diver wants breath, gas goes out from freeing pipe 7 again, breathe out from the balloon 8 of giving vent to anger through outgassing nonreturn valve 5 backs, give vent to anger balloon 8 then under the pressure of breath, the balloon 8 of giving vent to anger becomes big, the spilehole of giving vent to anger on the balloon 8 is opened, gas can be given vent to anger from the spilehole on the balloon 8 of giving vent to anger, and work as gas after rolling, the balloon 8 of giving vent to anger restores to the original state, and the spilehole on the balloon 8 of giving vent to anger is closed, in this process, extraneous water all can not flow in the balloon 8 of giving vent to anger, even flow in the balloon 8 of giving vent to anger, also can not influence scuba diver's breathing, on freeing pipe 7 because the outgassing nonreturn valve 5 that is provided with plays the effect of a unidirectional ventilation.When the scuba diver faces a danger, ball float 2 with enough buoyancy, the effect of buoy quoit can also be provided to the scuba diver, the scuba diver can be remained on the water surface, the rebreather of saving oneself of the present invention has advantages such as simple in structure, safe in utilization and low cost of manufacture.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
