When sea situation is very abominable, have more seawater and enter intake duct drain valve or the air outlet flue drain valve that blocks water that blocks water, flow into discharge bypass outlet in the bypath system and prevent in the arm between the wave exhaust hood through drain pipe.Because this arm volume is relatively large, the water yield of accumulating is limited, and exhaust process is unlikely to be affected.
Under opposite extreme situations, intake duct drain valve or the air outlet flue drain valve that blocks water that blocks water may be in temporary obstruction operating mode.Under this operating mode, the inlet and outlet bypass in the bypath system will play a role, and guarantee the continuous air inlet or the exhaust of combustion engine.At this moment the discharge bypass of bypath system discharges engine exhaust with the compartment of terrain with high pressure.This strand high pressure draught is by discharge bypass outlet and the arm discharge of preventing between the wave exhaust hood.Two branched pipes of this root arm itself link to each other with intake duct the block water drain pipe of drain valve of drain pipe and the air outlet flue of drain valve that blocks water respectively, because the jet-action of the high pressure draught in the bypath system, the water that these two drain pipes are drained finally enters atmosphere by anti-wave exhaust hood.
The present invention can be for shallow water type submersible combustion engine provides suitable ventilation condition under extremely abominable sea situation, guarantees the proper functioning of motor, guarantees that submersible does not need the floating water surface operation of diving under water continuously of going up.

Under the conventional operating mode, air is through the right-angle elbow pipe 35 of anti-wave airscoop shroud 6, enter the block water wet tube head 29 of air flue of drain valve 4 of intake duct, enter the inlet mouth of air flue bypath system by the block water air flue main head 23 of drain valve 4 of intake duct again, be communicated to the suction port of combustion engine 2 through intake duct three-way valve 10.Waste gas is discharged by the relief opening of combustion engine 2, air outlet flue three-way valve 10, air outlet flue by air flue bypath system 3 the block water wet tube head 29 of air flue of drain valve 5 of air flue main head 23, the air outlet flue of drain valve 5 that blocks water is connected to the elbow bend 35 of anti-wave exhaust hood 7 successively, thereby enters in the atmosphere.When air (perhaps waste gas) process is prevented wave airscoop shroud 6 (or anti-wave airscoop shroud 7),, also have only the seawater of trace to cross anti-wave airscoop shroud 6 (or anti-wave airscoop shroud 7) with air communication even run high.Intake duct subsequently blocks water in the drain valve 4 (or air outlet flue block water drain valve 5), even the seawater of trace can not pass through, seawater is blocked water outside drain pipe 31 expulsion valves of drain valve 5 by block water drain valve 4 and air outlet flue of intake duct, and the air-flow of guaranteeing to enter bypath system is dry.
When sea situation is very abominable, have more seawater and enter intake duct drain valve 4 or the air outlet flue drain valve 5 that blocks water that blocks water, flow into discharge bypass outlet in the air flue bypath systems 3 and prevent in the arm between the wave exhaust hood 7 through drain pipe 31.Because this arm volume is relatively large, the water yield of accumulating is limited, and exhaust process is unlikely to be affected.
Under opposite extreme situations, intake duct drain valve 4 or the air outlet flue drain valve 5 that blocks water that blocks water may be in temporary obstruction operating mode.Under this operating mode, the inlet and outlet bypass in the air flue bypath system in 3 will play a role, and guarantee the continuous air inlet or the exhaust of combustion engine 2.At this moment the discharge bypass of air flue bypath system 3 discharges engine exhaust with the compartment of terrain with high pressure.This strand high pressure draught is by discharge bypass outlet and the arm discharge of preventing between the wave exhaust hood 7.Two branched pipes of this root arm itself link to each other with intake duct the block water drain pipe 31 of drain valve 5 of drain valve 4 and air outlet flue that blocks water respectively, because the jet-action of the high pressure draught in the bypath system 3, the water that these two drain pipes 31 are drained finally enters atmosphere by anti-wave exhaust hood 7.
