Abstract
The invention provides a ship resistance reducing device which comprises a main engine, an exhaust turbine compressor, an air inlet pipe, an air feeding pipe and an air injection pipe, wherein a plurality of air injection holes are formed in the pipe wall of the air injection pipe; the air injection pipe is mounted below a ship body and mostly stretches out of a ship head; the air inlet pipe is arranged above the ship body, and is hermetically and fixedly connected with the air feeding pipe; the air feeding pipe is fixedly connected with the exhaust turbine compressor; and one end of the air injection pipe is connected with the exhaust turbine compressor. According to the adopted ship resistance reducing device, the frictional resistance during sailing is reduced through releasing bubbles to the outer surface of the ship body of a ship, and the resistance is reduced through ejecting bubbles through utilizing the exhaust gas discharged by the main engine, so that the energy utilization rate is increased, and the sailing resistance of the ship is reduced.
Description
Technical field
The present invention relates to hull fittings, be specifically related to a kind of ship drag reduction device.
Background technology
Pursuit speed is a kind of original serious hopes of the mankind, water transportation instrument has just had only wooden boat in time immemorial, modern age, marine communication means at a high speed had speedboat, air cushion vehicle, injection water power propelling ship etc., these ships have a common ground, friction force exactly in order to overcome water and hull pays great cost, when ship is exercised forward, hull contacts with water and produces relative movement, because water has adhesive force to hull, the friction force that between water with hull, generation one is contrary with shipping agency direction, this friction force is exactly the power stoping ship to advance, so will advancing of ship must have propulsive effort to overcome this friction force, when height speed goes height constantly, the friction force stoping it to advance is increasing, until ship can not accelerate again, at present in order to the normally used way of running velocity adding fast boat is the propelling thrust increasing ship, but the increase of power can constantly increase the cost travelled, up to now, not yet there is this difficult problem of contradiction between the friction force that a kind of technology can solve when ship advances at utmost speed between hull and water well.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of and wears conveniently, not easily departs from, urinary catheter is fixed reliably, comfort level is high Simple urine pipe band.
In order to solve the problems of the technologies described above, the invention provides a kind of ship drag reduction device, it is characterized in that, it comprises sustainer, main engine, exhaust turbo-compressor machine, air inlet pipe, air feed pipe, gas ejector pipe, described gas ejector pipe tube wall is provided with multiple fumarole, described gas ejector pipe is arranged on below hull, and stretch out bow more, described air inlet pipe is located at above hull, described air inlet pipe is sealedly and fixedly connected in described air feed pipe, described air feed pipe is fixedly connected with described exhaust turbo-compressor machine, and described gas ejector pipe one end connects and described exhaust turbo-compressor machine.
Preferably, described driving engine is connected to air feed pipe one end.
Implement a kind of ship drag reduction device of the present invention, compared with prior art, there is following beneficial effect: (1) at hull bottom surface and side ejection bubble by gas ejector pipe, is greatly lowered the friction drag produced when boats and ships contact with water, accelerated shipping sail speed.(2) by air feed pipe, boats and ships sustainer, main engine waste gas is delivered to gas ejector pipe, utilize waste gas jet, decrease energy dissipation, environmental protection is practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the embodiment of the present invention, be briefly described to the accompanying drawing of embodiment below.
Fig. 1 is the lateral plan of one embodiment of the invention.
Detailed description of the invention
The specific embodiment of the present invention is further described below in conjunction with accompanying drawing.
In conjunction with shown in Figure 1, a kind of ship drag reduction device, it is characterized in that, it comprises sustainer, main engine 1, exhaust turbo-compressor machine 3, air inlet pipe 2, air feed pipe 4, gas ejector pipe 5, and described gas ejector pipe 5 tube wall is provided with multiple fumarole, described gas ejector pipe 5 is arranged on below hull, and stretch out bow, described air inlet pipe 2 is located at above hull more, and described air inlet pipe 2 is connected to described exhaust turbo-compressor machine 3, described air feed pipe one end connects described exhaust turbo-compressor machine 3, and the other end connects described gas ejector pipe 5.During concrete enforcement, connect between all pipelines and be airtight being fixedly connected with.Described driving engine 1 is connected to air feed pipe 4 one end.The waste gas that such driving engine produces just is sent to exhaust turbo-compressor machine by air feed pipe, adds barometric pressure be transported to the jet use of gas ejector pipe by exhaust turbo-compressor machine.
Above disclosedly be only preferred embodiment of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the present patent application the scope of the claims is done, still belong to the scope that the present invention is contained.
