It is furnished with ventilation pipe network, the snorkel is evenly equipped with fumarole on the net.
The gas compressing apparatus is exhaust-driven turbo-charger exhaust-gas turbo charger.
The exhaust end of the gas compressing apparatus is connected with aerial cooler.
It is equipped with air accumulator between the gas compressing apparatus and Pneumatic controller, pressure release is installed on the air accumulator
Valve.
The middle front part of the bubble generator arrangement alow.
The bubble generator is fabricated from a flexible material.
The beneficial effects of the utility model are:
Air is compressed by gas compressing apparatus and passes through Pneumatic controller, stable air pressure is delivered to bubble hair
Generating apparatus, air pressure enter ventilation pipe network, are then discharged from fumarole, form air film in the bottom of hull, reduce the navigation of ship
Resistance reduces the underway energy consumption and operation cost of ship.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model embodiment.
Fig. 2 is the schematic diagram that the utility model embodiment is mounted on ship.
Fig. 3 is the schematic diagram of the utility model embodiment bubble generator.
Gas compressing apparatus 1, Pneumatic controller 2, bubble generator 3, ventilation pipe network 4, fumarole 5, air are cooling
Device 6, air accumulator 7, relief valve 8.
Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing:
In embodiment, as shown in Figure 1, Figure 2, Figure 3 shows, air layers reducing resistance device, including gas compressing apparatus 1, the gas pressure
Compression apparatus 1 is connected with Pneumatic controller 2 and bubble generator 3 in turn, and the bubble generator 3 is arranged in hull
Bottom is equipped with inside the bubble generator 3 and is evenly equipped with ventilation pipe network 4, is evenly equipped with fumarole 5 on the ventilation pipe network 4.It is logical
It crosses gas compressing apparatus 1 air is compressed and passes through Pneumatic controller 2 and stable air pressure is delivered to bubble generator 3,
Pneumatic controller 2 includes pressure gage, flowmeter, solenoid valve and single-chip microcontroller, and pressure gage, flowmeter convey measurement data
To single-chip microcontroller, single-chip microcontroller controls solenoid valve and guarantees the throughput of output and the stability of pressure, and air pressure enters ventilation pipe network 4, so
It is discharged afterwards from fumarole 5, forms air film in the bottom of hull, reduce the ship resistance of ship, reduce the underway of ship
Energy consumption and operation cost.
In embodiment, as shown in Figure 1, the gas compressing apparatus 1 is exhaust-driven turbo-charger exhaust-gas turbo charger.

Gas enters after gas compressing apparatus 1 compressed by high compression ratio after can generate very high heat, aerial cooler 6 by gas cooling,
Preventing the gas of high heat from entering other equipment makes equipment damage.
In embodiment, as shown in Figure 1 and Figure 2, air accumulator is equipped between the gas compressing apparatus 1 and Pneumatic controller 2
7, relief valve 8 is installed on the air accumulator 7.It will first be stored in air accumulator 7 after compressed air cooling, filled by pressure control
2 adjusting air output pressures are set to guarantee that gas bubble generator 3 can steadily generate bubble, relief valve 8 can guarantee to store up
The safety of gas can be with automatic deflation pressure release once pressure is more than margin of safety.
In embodiment, as shown in Fig. 2, the middle front part of the arrangement of the bubble generator 3 alow.The size of jet area
The size of air film area is not represented, experiment shows to reduce jet area into half, and in the case where no reduction jet area
Resistance be compared, there are not significant changes in Resistance Value；When ship is with certain speed of a ship or plane navigation, it is located at hull bottom middle front part
Bubble generator 3 successively release can also cover the middle and back of hull bottom to a certain extent, keep the bottom of hull whole
The material of bubble generator 3 is saved in covering.
In embodiment, the bubble generator 3 is fabricated from a flexible material.Material can be plastic film, be also possible to
Rubber film, bubble generator 3 are spliced by film, and monolithic films are having a size of 2000mmx6000mm, with a thickness of 100mm.
