Description
Technical field
The present invention relates to a kind of engine breathing implication cover, especially a kind of anti-wave gas hood that is used for submersible combustion engine porting belongs to Power Machinery Engineering technical field combustion engine category.
Background technique
Present known combustion engine porting mostly is straight-through type greatly, is straight-through type by Zhou Longbao chief editor, China Machine Press at the D/TBD234 motor and the 6110B diesel engine of " internal-combustion engine " description that publish in June, 1996; In the prior art, the patent No. is that 02257340.2 " multifuel engine device " utility model patent and the patent No. are that 01227296.5 " air inlet improved device " is though the porting in the utility model patent has the windproof and rain proof function, but when motor moves and porting need be placed in the height on sea and often stand the impact of wave and when patting under water, has the combustion engine porting of windproof and rain proof function owing to stop up or water inlet all can't proper functioning, cause engine retard and flame-out the parking easily, even the cylinder water inlet takes place and impaired, break down.
Summary of the invention
In order to overcome the deficiency that existing combustion engine porting can not prevent that sea beat is patted, the invention provides the anti-wave gas hood of a kind of porting, this gas hood not only can windproof and rain proof, and can resist the attack of wave and wash away, even the porting of combustion engine is in the position, sea, also can guarantee the motor proper functioning by this invention.
The technical solution adopted for the present invention to solve the technical problems is: the anti-wave gas hood of this submersible combustion engine porting is made up of inflator, inverted U-shaped adapter, conical water container and right-angle elbow pipe four major parts.Inflator is a cylindrical tube, and the conical air flue of going up has been installed on top, is stamped a domed tarpaulin on the last air flue.Tarpaulin and last air flue keep certain distance by supporting, to guarantee that the smooth and easy of air-flow passes through.The lower edge of tarpaulin is lower than goes up the air flue upper edge, with the wave that stops all angles by inflator intrusion inflator suitable for reading.
The bottom of inflator is connected with two cylindrical downtakes.The medial axis of two downtakes all with the axis of inflator angle at 45, make air-flow current therein easily, and laterally and wave vertically upward can not enter inflator.The outer surface bearing of downtake Saxboard, oblique upper to wave can not enter inflator.Even idol has wave invasion and attack water inlet, also can successfully discharge inflator rapidly.
The upper left side of inflator is connected with the reverse-U-shaped tube right-hand member by a downward-sloping adapter, and the reverse-U-shaped tube left end links to each other with conical water container upper end.The lower end of conical water container links to each other with the piston slideway, the draining piston of settling in the piston slideway can slide up and down, the spring very little with elasticity coefficient is supported on piston base, has residual water will oppress piston in the conical water container slightly and moves down, and makes residual water in time by outside the waste pipe discharge tube.The upper left side of conical water container is by a right angle bend pipe, and what be connected to combustion engine advances (row) gas port.
At the combustion engine porting an anti-wave gas hood is installed respectively, when engine operation, atmosphere passes inflator by last air flue or downtake, through tilting to take over and reverse-U-shaped tube, passes conical water container and right-angle elbow pipe and enters in the motor; The waste gas that engine exhaust port is discharged is discharged by this gas hood.Take over the invasion that has prevented seawater by tarpaulin, baffle plate and reverse-U-shaped tube and inclination, and carry out seawater by downtake, the waste pipe that is connected conical water container and draining piston and drain, thereby make seawater can't enter the intake and exhaust port of motor, can not influence the proper functioning of submersible combustion engine.
The present invention can make the combustion engine windproof and rain proof, prevent the attack of multi-direction wave, simple in structure, easily manufactured, have substantial advantage and higher engineering use value.

Embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present invention is described further.
As shown in Figure 1, the present invention includes inflator 1, reverse-U-shaped tube 2, conical water container 3 and right-angle elbow pipe 4 four major parts.Inflator 1 is a cylindrical tube, and the conical air flue 12 of going up is installed on top, is stamped domed tarpaulin 5 on the last air flue 12.Tarpaulin 5 is bearing in air flue 12 tops and keeps certain distance with last air flue 12, and the lower edge of tarpaulin 5 is lower than goes up air flue 12 upper edges.The bottom of inflator 1 links to each other with two cylindrical downtakes 7, the axis of two downtakes 7 all with inflator axis angle at 45.By supporting 6 Saxboards 13 are installed in the outlet port of downtake 7, are made air-flow current at downtake easily, and laterally, vertically upward and the wave of oblique upper can not enter inflator 1, idol has wave invasion and attack water inlet, also can successfully discharge inflator 1 rapidly.The upper left side of inflator 1 links to each other with reverse-U-shaped tube 2 right-hand members by tilt taking over 14.The left end of reverse-U-shaped tube 2 is connected with conical water container 3 upper ends, the lower end of conical water container 3 connects piston slideway 11, draining piston 8 is installed in the piston slideway 11, in draining piston 8 bottom mounting spring 9, the elasticity coefficient of spring 9 is very little, having residual water will oppress piston slightly in the conical water container moves down, makes residual water in time by outside waste pipe 10 discharge tubes.(row) gas port is advanced by what right-angle elbow pipe 4 was connected to combustion engine in the upper left side of conical water container 3.In conical water container 3 bottoms waste pipe 10 is housed.
At the combustion engine porting an anti-wave gas hood is installed respectively, when engine operation, atmosphere passes inflator 1 by last air flue 12 or downtake 7, through adapter 14 and the reverse-U-shaped tube 2 of tilting, passes conical water container 3 and right-angle elbow pipe 4 and enters in the motor; The waste gas that engine exhaust port is discharged is discharged by this gas hood.Prevented the invasion of seawater by tarpaulin 5, baffle plate 13 and reverse-U-shaped tube 2 and the adapter 14 of tilting, and carry out seawater by downtake 7, waste pipe 10 and draining piston 9 and drain, thereby make seawater can't enter the intake and exhaust port of motor, can not influence the proper functioning of submersible combustion engine.
