Abstract
The invention discloses a device mounted on ship for reducing sailing resistance, which comprises an air compressor arranged in the ship body and a bubbling pipe arranged on the outer side of the ship bottom along a keel line. One end of the bubbling pipe is connected with an air outlet of the air compressor by a pipeline. The bubbling pipe is located beneath the water surface. The device has the following advantages: 1, the device is used for reducing the friction resistance between the ship body and water, which is not as good as the air cushion manner but easier than the air cushion manner in implementation, the sailing speed of the ship is enhanced greatly without the great change on the ship body, and the fuel oil is saved in abundance; 2, the device is simpler and can reduce the friction resistance between the ship body and water in use, and the device can be used in various ships conveniently, even supersized ships and also can be used in the improvement of various old ships easily; and 3, the device only needs low cost.
Description
Technical field
The present invention relates in the ship's navigation process technical field with the friction drag related aspect, specifically refer to a kind of device that significantly reduces the friction drag that water in the ship's navigation process forms hull.
Background technology
Well-known air cushion vehicle can the decrease hull and water between friction force, but since air cushion vehicle to the specific (special) requirements of hull bottom, this method can only be used for some spitkit, is difficult to use at relatively large boats and ships.And can't be for the transformation of obsolete vessel.
Summary of the invention
The objective of the invention is by designing a kind of bubbling device, be installed in the bottom of boats and ships, utilize this device that the air bubble spreading is local to the major part that hull contacts with water, make hull and contacting of water change the contacting of compound of hull and air bubble and water into, reach and significantly reduce water to the friction of hull, thereby reach the route speed that significantly improves boats and ships.
Purpose of the present invention is achieved through the following technical solutions:
A kind of device that is installed on the boats and ships for reducing running resistance, comprise and be located at the interior air compressor of hull and be arranged at the basolateral bubbling pipe of ship along keel line, one end of bubbling pipe is communicated with the air compressor air extractor duct by pipeline, and bubbling pipe is positioned at below the water surface.
Preferably, described bubbling pipe is that tube wall is with the metal tube of porosity.
Preferably, described bubbling pipe is steel pipe.
Preferably, do not have pore on the tube wall of the pipeline of described connection bubbling pipe and air compressor, this pipeline can be selected metallic material or non-metallic material.
The selected air compressor of the present invention is to be driven or diesel driven by electricity, pressure is about several barometric pressures (size according to boats and ships is decided), it is fixed that the size of its free air capacity also is that the size according to boats and ships also has route speed, and the thickness of bubbling pipe of the present invention and the diameter of aperture also are fixed according to the size of boats and ships.
Compared with prior art, apparatus of the present invention have the following advantages:
Although the friction drag that 1, utilizes this device to reduce hull and water is not so good as the air cushion mode, it is than the easier realization of air cushion mode, and does not need hull is done large change, just can significantly improve the route speed of boats and ships, and save in a large number fuel oil.
2, apparatus of the present invention are comparatively simple, and the friction drag that utilizes this device to reduce hull and water can be applied on the various boats and ships easily, or even on the superhuge boats and ships; Also can be easy to be applied in the transformation of various obsolete vessels.
3, apparatus of the present invention only need cheap cost.
Description of drawings
Fig. 1 is a kind of structural representation that apparatus of the present invention are used at boats and ships.
The specific embodiment
Below in conjunction with specific embodiment the present invention is done further concrete detailed description the in detail, but embodiments of the present invention are not limited to this, the technological parameter for not indicating especially can carry out with reference to routine techniques.
Embodiment 1
A kind of device that is installed on the boats and ships for reducing ship resistance, comprise the air compressor 2 be located in the hull 1 and be arranged at the basolateral bubbling pipe 2 of ship along keel line, one end of bubbling pipe 2 is communicated with air compressor 2 air extractor ducts by pipeline 4, described bubbling pipe 2 be tube wall with the steel pipe of porosity, do not have pore on the tube wall of pipeline 4.Bubbling pipe 2 is in below the water surface always in the navigation.
Operational process:
When boats and ships just in motion, air compressor by loading vessel, constantly pump into pressurized air to the steel pipe that is attached thereto, pressurized air arrives the lengths of steel pipes that is in the densely covered aperture in water surface below, air overflows from the steel pipe walls aperture, forms countless minute bubbles in the both sides of ship, and hull and water are separated, thereby greatly reduce the friction force between hull and the water, reach the purpose that improves ship's speed and reduce oil consumption.
Above-described embodiment is the better embodiment of the present invention; but embodiments of the present invention are not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present invention and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
Claims (4)
1. device that is installed on the boats and ships for reducing running resistance, it is characterized in that, comprise and be located at the interior air compressor of hull and be arranged at the basolateral bubbling pipe of ship along keel line that one end of bubbling pipe is communicated with the air compressor air extractor duct by pipeline, bubbling pipe is positioned at below the water surface.
2. device according to claim 1 is characterized in that, described bubbling pipe is that tube wall is with the metal tube of porosity.
3. device according to claim 2 is characterized in that, described bubbling pipe is steel pipe.
