Abstract
The utility model relates to a kind of scalable enclosure device for boats and ships resistance reduction by air cavity system, and object is to overcome prior art deficiency, provides a kind of and former drinking water can be kept constant, avoid the resistance reduction by air cavity enclosure device causing additional resistance.Drip irrigation device is: by longitudinal baffle, fore and aft diaphragm, hydraulic actuating cylinder, watertight case, and piston rod forms; Its annexation is: the piston rod of hydraulic actuating cylinder is connected with longitudinal baffle and fore and aft diaphragm through watertight case, and hydraulic actuating cylinder is connected with hull bottom.Retractable baffle design of the present utility model can keep former ship at the designed draft of shallow draft waterway, and the additional resistance that when avoiding not jet, enclosure device causes, strengthens drag reduction and energy-saving effect, can also prevent seawater from immersing hull interior.
Description
Technical field
The utility model relates to a kind of scalable enclosure device, be mainly used in bottom of ship resistance reduction by air cavity.
Background technology
Boats and ships resistance reduction by air cavity is a kind of by covering the gas-bearing formation of hull bottom to reduce the technology that hull wetted surface area reduces sailing hull friction drag to the jet formation of hull bottom.The key realizing this drag reduction technology is formed alow and keeps uniform gas-bearing formation.
Resistance reduction by air cavity technology is applied in the country on real ship by the former Soviet Union in the world the earliest, and successively devise two kinds of boats and ships resistance reduction by air cavity systems, the enclosure device adopted is respectively hull bottom groove and longitudinal baffle.The shortcoming one of these two kinds of enclosure devices is: due to the displacement that can lose hull of slotting alow, in order to keep former drinking water constant, must reduce the cargo capacity of ship; Because hull bottom longitudinal baffle is obviously beyond the base plane of ship, when ship navigates by water at shallow draft waterway, drinking water must be reduced, its cargo capacity therefore also can be caused to reduce.Two be when ship navigate by water under severe sea condition or have navigate by water in remarkable original trim situation time, the drag-reduction effect of resistance reduction by air cavity system can significantly reduce, the power of jet consumption exceedes the power of drag reduction saving, cannot obtain energy-saving effect, therefore needs stopping jet.But time not jet, compared with former conventional ship type, slotting alow or installing longitudinal baffle additional all can cause additional resistance.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of scalable enclosure device, and when ship navigates by water at shallow draft waterway, hull interior of being retracted by enclosure device, just can keep former drinking water constant.When ship navigate by water under severe sea condition or have navigate by water in remarkable original trim situation time, hull interior of being retracted by enclosure device, just can avoid causing additional resistance.
The utility model object is realized by following technical proposal:
For a scalable enclosure device for boats and ships resistance reduction by air cavity system, comprise longitudinal baffle, fore and aft diaphragm, hydraulic actuating cylinder, watertight case, piston rod; Its annexation is: the piston rod of hydraulic actuating cylinder is connected with longitudinal baffle and fore and aft diaphragm through watertight case;
Described longitudinal baffle and fore and aft diaphragm are the dividing plates being longitudinally arranged at hull bottom both sides along hull, symmetrical about line of centers, vertical with hull bottom, its length is according to hull bottom Design of length, the area that longitudinal baffle is surrounded is maximum, its height can carry out telescopic adjustment according to voyage conditions, maximum height is 0.8 meter, four dividing plates are divided into three wide air cavitys hull bottom, configure watertight case above longitudinal baffle and fore and aft diaphragm, longitudinal baffle and fore and aft diaphragm can control by hydraulic actuating cylinder up-and-down movement the height stretching out watertight case;
Described watertight case is arranged at the hull bottom position of corresponding longitudinal baffle and fore and aft diaphragm in hull, and its inside just covers retraction longitudinal baffle and fore and aft diaphragm;
Described hydraulic actuating cylinder is positioned at above watertight case and is connected with hull bottom; The piston rod of hydraulic actuating cylinder is connected with fore and aft diaphragm with longitudinal baffle through watertight case.
Owing to taking technique scheme, the utility model tool is had the following advantages and effect:
1, longitudinal baffle and fore and aft diaphragm are designed to telescopic, by means of hydraulic actuating cylinder up-and-down movement retraction hull interior and hull bottom can be stretched out, therefore former ship can be kept at the designed draft of shallow draft waterway, the additional resistance that when can also avoid not jet, enclosure device causes, strengthens the synthesis energy saving effect of system.
2, longitudinal baffle and fore and aft diaphragm according to voyage conditions, can control the length of stretching out hull bottom, to adapt to the requirement to gas-bearing formation under different voyage conditions, reach the object strengthening resistance reduction by air cavity effect and energy-saving and emission-reduction.
3, the longitudinal baffle of watertight Bin covering retraction hull interior and fore and aft diaphragm, forms water-tight structure, can prevent seawater from immersing hull interior.
Accompanying drawing explanation
Fig. 1 is the overall birds-eye view of the utility model.
Fig. 2 is cross sectional drawing of the present utility model and working process schematic diagram.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 2, a kind of scalable enclosure device for boats and ships resistance reduction by air cavity system, comprises longitudinal baffle 3, fore and aft diaphragm 4, hydraulic actuating cylinder 5, watertight case 6, piston rod 8 to described utility model; Its annexation is: the piston rod 8 of hydraulic actuating cylinder 5 is connected with longitudinal baffle 3 and fore and aft diaphragm 4 through watertight case 6;
Described longitudinal baffle 3 and fore and aft diaphragm 4 as shown in Figure 2, are longitudinally arranged at the dividing plate of hull bottom 2 both sides along hull 1, symmetrical about line of centers, vertical with hull bottom 2; Its length is according to hull bottom 2 Design of length, and the area that longitudinal baffle is surrounded is maximum, and its height can carry out telescopic adjustment according to voyage conditions, and maximum height is 0.8 meter; Four dividing plates are divided into three wide air cavitys hull bottom 2, configure watertight case 6 above longitudinal baffle 3 and fore and aft diaphragm 4, and longitudinal baffle 3 and fore and aft diaphragm 4 can control by hydraulic actuating cylinder 5 up-and-down movement the height stretching out watertight case 6;
As shown in Figure 2, be arranged at hull bottom 2 position of corresponding longitudinal baffle 3 and fore and aft diaphragm 4 in hull 1, its inside just covers retraction longitudinal baffle 3 and fore and aft diaphragm 4 to described watertight case 6;
