Abstract

The utility model relates to the exhaust unit of a water-cooled engine apparatus for a remote-control ship, comprising a holding box communicated with the venting hole of the engine apparatus. One side end of the holding box is provided with a water inlet, and the other end is provided with an exit having a double tube structure. Because the double tube structure is adopted, the exhaust gas and the cooling water dose not compete for a tube when discharged out of the ship. Thus the noise is decreased, and the driving horsepower of the engine is increased.

Description

Exhaust unit of water-cooled engine apparatus for remote-control ship

The utility model relates to drone ship, refers to that especially a kind of drone ship that can make the time can reduce the exhaust gear of drone ship water-cooled engine apparatus that noise increases the drive horsepower of its engine in action.

The water-cooled engine apparatus of existing drone ship utilizes purt water member that engine sets up 1 by the hull afterbody water to be drawn into engine internal, reach a kind of effect of water-cooled cooling, as shown in Figure 1, and the water that will finish cooling sends engine, received and discharged outside the hull together with waste gas by exhaust gear 2.General exhaust gear 2 commonly used only is single body design, and necessary in the use discharging waste gas and cooling water expansion tank simultaneously, so the state that causes waste gas and cooling water expansion tank to strive in this single freeing pipe causes whole engine exhaust and draining sound very noisy.And waste gas certainly will influence the exhaust of engine because of striving with cooling water expansion tank, even thereby consume the horsepower of engine running, be difficult to bring into play its normal due usefulness.

In view of this, the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of exhaust gear of drone ship water-cooled engine apparatus is proposed, this device utilizes the dual exhaust structure, can distinguish discharging waste gas and cooling water expansion tank, make both not strive the phenomenon of squeezing, can reduce noise and improve the operational paradigm of engine.

The exhaust gear that the utility model proposes comprises a storage box, this storage box is provided with the aperture that is connected water cooling engine exhaust hole, be located at inlet opening and the outlet of being located on its another side on the one side, the free-standing double pipe structure that separates with upper strata freeing pipe and lower floor's drain hose is adopted in this outlet, make waste gas and cooling water expansion tank road out of question discharge outboard respectively, reduce noise thus and increased the drive horsepower of engine.

Details are as follows to the utility model below in conjunction with preferred embodiment and accompanying drawing, among the figure:

Fig. 1 is the block diagram of the water-cooled engine apparatus of existing single hose exhaust gear;

Fig. 2 is the block diagram that the utility model adopts the water-cooled engine apparatus of dual exhaust device;

Fig. 3 is the generalized section of dual exhaust device in the utility model.

See also Fig. 2 and Fig. 3, the drone ship water-cooled engine apparatus that the utility model proposes has adopted the dual exhaust device, makes the waste gas of engine emissions and cooling water expansion tank can discharge outboard respectively independently in the dual exhaust device.The utility model comprises that a deflation hole with the water-cooled engine links to each other and has storage box 3 than large space, one side of this storage box 3 is provided with inlet opening 31, the cooling water expansion tank of discharging for water-cooled engine purt water member 1 enters in the storage box 3, another side of storage box 3 then is provided with exhaust outlet 32, and this exhaust outlet 32 is arranged to have the free-standing dual exhaust structure of separating of upper strata freeing pipe 321 and lower floor drain hose 322, make the waste gas and the cooling water expansion tank that are received in the storage box 3 improve existing respectively via two-tube discharge outboard with the shortcoming that exists in the single tube discharge structure.Integral structure setting of the present utility model is that the aperture 4 by storage box 3 is connected in the deflation hole of water-cooled engine, to be connected the waste gas that the water-cooled engine is discharged, and receive the cooling water expansion tank that purt water members 1 are sent by the inlet opening 31 of side setting, make storage box 3 in the middle of the engine running, can receive the waste gas and the cooling water expansion tank of discharge simultaneously, and because of the weight density of cooling water expansion tank greater than waste gas, so it can be in the lower floor position in storage box 3, and via lower floor's drain hose 322 discharge outboards, and waste gas is because of being lighter than cooling water expansion tank, so can discharge outboard smoothly by upper strata freeing pipe 321, form the structure that a kind of waste gas and cooling water expansion tank are discharged via different independent tubes respectively, the bad phenomenon that unlikely generation waste gas and cooling water expansion tank are striven, promptly do not have the noise existence that noisy air water is striven, increased the smooth and easy characteristic of blow down gas and cooling water expansion tank, and can be because of the smooth discharging of waste gas, reduce the ill effect of vapour lock, increase the horsepower benefit of water-cooled engine running.

In sum, the utility model can not only overcome the shortcoming that exists in the prior art, and simple in structure, and is easily manufactured, has practicality.
