Abstract
The utility model relates to an air supply system of an air cavity drag-reduction ship, which is characterized in that: the air supply system of the air cavity drag-reduction ship comprises a blower cabin, an air inlet pipe on a deck of the head part of the air cavity drag-reduction ship is communicated with the blower cabin, a blower is arranged in the blower cabin, the blower sucks air from the blower cabin, the air inlet of the blower is connected with a pressure stabilization chamber which is connected with the air cavity of the air cavity drag-reduction ship by a rectangular air duct. In the utility model, the blower and the pressure stabilization chamber are utilized to ensure the air supply flow rate of the air cavity of the air cavity drag-reduction ship and the pressure stabilization and improve the seakeeping and stabilization of the air cavity drag-reduction ship.
Description
Technical field
The utility model relates to a kind of air cavity drag reduction ship, especially relates to a kind of gas supply system of air cavity drag reduction ship.
Background technology
Compare with conventional ship, the hull bottom of air cavity drag reduction ship has unique air cavity structure, and by gas supply system to the air cavity air feed.During the navigation of air cavity drag reduction ship, the air that gas supply system need provide certain air pressure and flow is endlessly isolated with the part bottom surface and the water that keep hull to air cavity, thereby reduction resistance, improve propulsion coefficient, therefore, gas supply system is an extremely important ring in the air cavity drag reduction ship.In the prior art, the gas supply system of air cavity drag reduction ship adopts Air compressor to the air cavity air feed usually, when gas leakage is very fast in the air cavity, when especially air cavity drag reduction ship navigates by water in wave, hull takes place oblique than heavy list in wave, and the gas leakage meeting in the air cavity is very fast, and Air compressor is to the flow and the pressure transient of air cavity air feed, cause the instability of gas-bearing formation in the air cavity, thereby directly influence the rough water quality and the stability of air cavity drag reduction ship.
The utility model content
The applicant has carried out research and has improved at above-mentioned problem, and the gas supply system of the air cavity drag reduction ship of a kind of gas supply flow and pressure stability is provided, and improves the rough water quality and the stability of air cavity drag reduction ship.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of gas supply system of air cavity drag reduction ship, comprise the blower fan cabin, the blast pipe that is arranged on the air cavity drag reduction bow portion deck is communicated with the blower fan cabin, blower fan is installed in the blower fan cabin, blower fan air draught from the blower fan cabin, the air outlet of blower fan connects pressure stabilizing chamber, and pressure stabilizing chamber connects the air cavity of air cavity drag reduction ship by rectangular air duct.
Further:
Be provided with one-way control valve in the described rectangular air duct.
Technique effect of the present utility model is:
The gas supply system of the disclosed a kind of air cavity drag reduction ship of the utility model utilizes blower fan and pressure stabilizing chamber to guarantee to improve the rough water quality and the stability of air cavity drag reduction ship to the air cavity gas supply flow of air cavity drag reduction ship and stablizing of pressure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises blower fan cabin 7, blower fan cabin 7 is arranged on air cavity drag reduction ship 9 stems usually, the blast pipe 1 that is arranged on the air cavity drag reduction ship 9 stem decks is communicated with blower fan cabin 7, blower fan 2 is installed in the blower fan cabin 7, blower fan 2 air draught from blower fan cabin 7, the air outlet of blower fan 2 connects pressure stabilizing chamber 3 by pipeline 8, pressure stabilizing chamber 3 connects the air cavity 6 of air cavity drag reduction ship by rectangular air duct 4, be provided with one-way control valve 5 in the rectangular air duct 4, one-way control valve 5 can prevent that the air in the air cavity 6 from issuing refluence in some extraordinary circumstances and entering pressure stabilizing chamber 3.
During the utility model work, extraneous air flows in the blower fan cabin 7 from blast pipe 1, blower fan 2 is directly air draught from blower fan cabin 7, compress after pipeline 8 enters pressure stabilizing chamber 3 by blower fan 2, pressurized air enters in the air cavity 6 of hull bottom by rectangular air duct 4 after the pressure stability in pressure stabilizing chamber 3 again, thereby hull and water are isolated, reach the effect of falling resistance.
