Abstract
The utility model relates to an air source underwater breathing apparatus, which comprises a suction tube, a discharge tube, a suction check valve, a discharge check valve, and a spare check valve and an inter-seal-connecting mask. The suction tube and the discharge tube are parallel through the center of the rescue boat and communicated at the geometry center place, the two top ends are equipped with waterproof rings. A plurality of water plugs are positioned at both inner ends of the geometry center bore of the breathing boat. Water is difficulty to enter and easy to discharge, thus ensures the safety of underwater rescue. The breathing boat is more safety and can not be pulled into the water.
Description
It is rebreather under the underwater breathing apparatus of source of the gas, particularly deep water, the burbulent regimen condition with the atmosphere that the utility model relates to a kind of.
Background technology
More later-model rebreather is that I apply at present, the patent No. is 01244499.5,02263436.3 rebreather, it mainly is made of float, aspirate tube, drain hose, face shield etc., liner steel wire in aspirate tube, the freeing pipe, aspirate tube communicates with float geometric centre hole in float geometric centre place, freeing pipe process float geometric centre place (near), upper port is exposed outside the float, check valve is all arranged in aspirate tube, the freeing pipe, and all be connected with mask seal.But when the diameter of the diameter in geometric centre hole and air inlet and exhaust piper was suitable, the aspirate tube that inserts the geometric centre hole formed the current that enter the geometric centre hole and stops, is difficult for flowing out, thereby overflows into aspirate tube; Because freeing pipe is through near the geometric centre, the space at geometric centre place is accounted for by the geometric centre hole, thereby has reduced the minor increment (when freeing pipe with the water surface parallel) of freeing pipe with the water surface, and it is dangerous to form bigger exhaust pipe mouth water inlet; When float hour, when the people needed bigger rescue power in water, float can't provide, float is drawn in the water easily simultaneously, can not breathe safely.
Summary of the invention
In order to overcome the easily casual water in existing rebreather geometric centre hole, freeing pipe is near apart from water surface minor increment, float hour does not have the rescue effect to the people, easy-to-draw go under water to form breathe dangerous, the utility model provides a kind of deep water, burbulent water rebreather, the water that enters the geometric centre hole can freely be discharged, there is not the water phenomenon of overflowing, freeing pipe is the same with air inlet pipe, its distance apart from the water surface is " on average " " perseverance " distance (suppose water surface calmness, the float floating line degree of depth is constant), and float has the rescue effect to the people, float can not be drawn in the water, forms to breathe danger.
The technical scheme that its technical matters that solves the utility model adopts is: rebreather is made of float, aspirate tube, freeing pipe, face shield etc., liner steel wire in aspirate tube, the freeing pipe, the aspirate tube upper port communicates with the geometric centre hole in float geometric centre place, freeing pipe process float geometric centre place (near), upper port is exposed outside the float, aspirate tube, freeing pipe lower port are connected with mask seal, and check valve is all arranged in aspirate tube, the freeing pipe.With the enlarged-diameter in geometric centre hole, make it diameter much larger than aspirate tube; The upper port of freeing pipe is pierced into float to float (following general designation breathing float) geometric centre place communicate with the geometric centre hole, and relative with aspirate tube upper port (being the connection pipe upper port among the ZL02263436.3); One safety rescue float is set, aspirate tube, freeing pipe are walked abreast and pass, and through its center; Inboard, two ends, geometric centre hole after the expansion water stopper of limiting; The aspirate tube upper port exceeded breathe the float central cross-section, the freeing pipe upper port is lower than breathes the float central cross-section, and two mouths of pipe maintain a certain distance, and the aspirate tube upper port is joined and kept away hydrosphere greatly, and the drain hose upper port is joined and kept away hydrosphere for a short time.
The beneficial effects of the utility model are; the water that enters the geometric centre hole can freely be discharged; there is not the water phenomenon of overflowing; suction, freeing pipe are " on average ", " perseverance " distance apart from the distance of the water surface; the people can obtain the bigger rescue power of safety rescue float in water; breathe the safety guard-safeguard that float is subjected to safety rescue float, can not be drawn in the water, cause and breathe danger.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Among the figure: 1, lasso; 2, face shield; 3, unidirectional service valve (being the freeing pipe among ZL01244499.5, the ZL02263436.3); 4, one-way sucting valve; 5, one-way exhaust valve; 6, seal ring; 7, aspirate tube; 8, freeing pipe; 9, safety rescue float; 10, the stopper of restricting water supply; 11, keep away hydrosphere greatly; 12, keep away hydrosphere for a short time; 13, geometric centre hole (promptly 02263436.3 in center breather hole); 14, breathe float.
The specific embodiment
In the accompanying drawing illustrated embodiment, unidirectional service valve (3), one-way sucting valve (4), one-way exhaust valve (5) are tightly connected with face shield (2) respectively, face shield (2) edge studs with seal ring (6) and is connected with lasso (1), aspirate tube (7) lower port and one-way sucting valve (4), after freeing pipe (8) lower port and one-way exhaust valve (5) are tightly connected respectively, the parallel center of passing safety rescue float (9), their upper port penetrate breathing float (14) to its how much heart places relatively and communicate with geometric centre hole (13).The aspirate tube upper port exceeds breathes the float central cross-section, and the freeing pipe upper port is lower than breathes the float central cross-section, and two mouths of pipe maintain a certain distance, and the aspirate tube upper port is joined and kept away hydrosphere (11) greatly, and the freeing pipe upper port is joined and kept away hydrosphere (12) for a short time.The inboard, two ends, geometric centre hole (13) of breathing float (14) is provided with the stopper of restricting water supply (10).
Claims (2)
1, a kind of deep water, burbulent water rebreather, aspirate tube lower port and one-way sucting valve, freeing pipe lower port and one-way exhaust valve are tightly connected respectively, one-way sucting valve, one-way exhaust valve, unidirectional service valve all is connected with mask seal, there are seal ring and lasso in the face shield edge, the aspirate tube upper port penetrates the geometric centre place of breathing float and communicates with the geometric centre hole of breathing float, the freeing pipe upper port expose breathe float outer and through the geometric centre place of breathing float (near), it is characterized in that: aspirate tube, the parallel safety rescue float center of passing of freeing pipe, aspirate tube, the freeing pipe upper port penetrates breathing float to its geometric centre place relatively and communicates with the geometric centre hole, breathes the inboard limited water stopper in two ends, geometric centre hole of float.
2, deep water according to claim 1, burbulent water rebreather is characterized in that: the aspirate tube upper port has keeps away hydrosphere greatly, and the freeing pipe upper port has keeps away hydrosphere for a short time.
