Abstract
A marine self-priming pump water spray propelling outboard engine comprises an engine, a self-priming pump body, a water inlet pipe and a water outlet pipe. The engine is connected with the self-priming pump body. One end of the water inlet pipe is mounted on the self-priming pump body. The other end of the water inlet pipe is a water inlet which faces the advancing direction of a ship. One end of the water outlet pipe is connected with the top of the self-priming pump body. The other end of the water outlet pipe is a water outlet which is opposite to the advancing direction of the ship. A nozzle connected with the water outlet pipe through a universal joint is mounted at the water outlet of the water outlet pipe. The universal joint is connected with a directional operating lever. The nozzle is controlled to turn through the directional operating lever so as to control advancing direction of the ship. The brand new propelling manner of high-speed water spraying on water surface is adopted, wave-making resistance and eddy resistance during high-speed sailing of ships are reduced greatly, the unconquerable contradictory in acceleration of the underwater spraying propelling can be relieved, and high-speed, flexible and stable sailing performance is achieved.
Description
Technical field
The present invention relates to technical field of ships, specifically a kind of self-priming pump waterjet propulsion outboard engine peculiar to vessel.
Background technology
Traditional water-jet propelled craft is in hull bottom water inlet and water outlet to be set respectively, and between water inlet and water outlet, be connected with water pipe, near in the pipeline of hull afterbody water jet pump is being installed also, by water jet pump with the water inlet suction current waterpipe of current from hull bottom, make current from the water outlet ejection of hull afterbody through water jet pump again, thereby the acquisition onward impulse is pushed ahead boats and ships.Because water inlet and water outlet all are located at hull bottom, water-jet velocity is subject to certain restrictions, and therefore power consumption is larger.
Chinese patent 200200410104200.8 discloses a kind of water spraying propelling outboard motor, has the case member that sucks shell and ejection shell, the suction shell forms the curved tube shape stream that extends obliquely upward from the sucking hole of front end, and the ejection shell forms from the rear end that sucks shell and omits to the horizontal-extending flow channel to ejiction opening; Extend upward the casing of setting from case member; Be installed in the driving engine on the casing; Be configured in the gear case of case member the place ahead and sucking hole top; The driving longitudinal axis that is connected with driving engine; Approximate horizontal is arranged at the driven transverse axis that sucks in the shell and be connected with the driving longitudinal axis in gear case; Be fixed on the driven transverse axis and be used for the water of outside being sucked pressurization and from the impeller of ejiction opening ejection, it has the circumferential periphery edge that approaches the inner peripheral surface that sucks shell and the spiral fashion fin that forwards extends the front edge outer circumference portion that arranges from sucking hole; Be arranged near the pilot blade of ejiction opening of discharging shell.This invention propulsion coefficient is higher, but complex structure is installed and inconvenient maintenance.
Summary of the invention
The objective of the invention is for above-mentioned problems of the prior art, the self-priming pump waterjet propulsion outboard engine a kind of peculiar to vessel that provides overcomes outboard engine complex structure, installation and maintenance inconvenience and the larger defective of power consumption.
The present invention realizes that the technical scheme that above-mentioned purpose is taked is: a kind of self-priming pump waterjet propulsion outboard engine peculiar to vessel, comprise driving engine and self-priming pump main body, driving engine is connected with the self-priming pump main body, described self-priming pump waterjet propulsion outboard engine peculiar to vessel also comprises coolant inlet pipe and coolant outlet pipe, coolant inlet pipe one end is installed on the self-priming pump main body, the other end of coolant inlet pipe is water inlet, water inlet towards consistent with the working direction of hull; One end of coolant outlet pipe is connected with self-priming pump main body top, the other end of coolant outlet pipe is water outlet, water outlet towards opposite with the working direction of hull, the water outlet of coolant outlet pipe is equipped with nozzle, nozzle is connected by universal-joint with coolant outlet pipe, universal-joint is connected with direction joystick, thereby turns to the direct of travel of control hull by the direction joystick Control Nozzle.
The end that described coolant outlet pipe is connected with the self-priming pump main body is 3-5:1 with the internal diameter ratio of the other end that is connected with nozzle.
Described water inlet is provided with filter screen.
A kind of jet propelled boat, its afterbody are equipped with described self-priming pump waterjet propulsion outboard engine peculiar to vessel, and hull bottom is provided with water inlet and water outlet, the water outlet of hull bottom be connected the water inlet of self-priming pump waterjet propulsion outboard engine peculiar to vessel and connect.
The water inlet of described jet propelled boat is provided with filter screen.
The present invention compared with prior art has following beneficial effect:
(1) the present invention by take the initiative suction and on the afterbody water surface the brand-new propulsion mode of high-speed spray, the water of ejection drops on stern at a distance, wave making resistance and eddy resistance in the time of can greatly reducing the naval vessel and navigate by water at a high speed, alleviate the under water propulsion mode contradiction that is difficult to go beyond in the speed-raising problem of water injector, obtain at a high speed, flexible, stable navigation performance, for navigating by water at a high speed the wide prospect of having opened up in the naval vessel.
(2) the present invention possesses the function to water body oxygenation.Outboard engine is fixed, and high-speed spray can stir water body effectively on the water surface, realizes making temporarily the purpose that aerator uses to water bodys such as fishpond or reservoirs without electricity or power failure the time.
(3) the present invention can also be used as the draft engine use.Outboard engine is changed nozzle, connect water pipe, easy to use as draft engine usefulness, and ship does not need sucking tube in water.
(4) the present invention has better enjoying value.When being used for Shui nationality pleasure-boat, put coolant outlet pipe is high, the water of ejection can one waterfall of formation behind ship like this.
