Embodiment 1

[0017] Such as figure 1 As shown, a marine self-priming pump water jet propulsion outboard motor is composed of an engine 2, a self-priming pump main body 3, a water outlet pipe 4, a direction joystick 5, a universal joint 6, a nozzle 7 and a water inlet pipe 8.

[0018] Engine 2 is connected with self-priming pump main body 3, and one end of water inlet pipe 8 is installed on the self-priming pump main body, and the other end of water inlet pipe 8 is water inlet, and water inlet is provided with strainer, and the direction of water inlet and the forward direction of hull 1 Consistent; one end of the water outlet pipe 4 is connected to the top of the main body 3 of the self-priming pump, the other end of the water outlet pipe 4 is a water outlet, and the direction of the water outlet is opposite to the forward direction of the hull. A nozzle 7 is installed at the water outlet of the water outlet pipe 4, and the nozzle 7 It is connected with the water outlet pipe 4 through a un...

Embodiment 2

[0020] The connection relationship and position relationship are the same as those in Embodiment 1, only the ratio of the inner diameter of the end of the water outlet pipe 4 connected to the main body 3 of the self-priming pump to the other end connected to the nozzle is changed to 4:1.

Embodiment 3

[0022] The connection relationship and position relationship are the same as those in Embodiment 1, only the ratio of the inner diameter of the end of the water outlet pipe 4 connected to the main body 3 of the self-priming pump to the other end connected to the nozzle is changed to 5:1.

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 [0001] The invention relates to the technical field of ships, in particular to a marine self-priming pump water jet propulsion outboard motor. Background technique [0002] The traditional water-jet propulsion boat is provided with a water inlet and a water outlet respectively at the bottom of the hull, and a water pipe is connected between the water inlet and the water outlet. A water jet pump is also installed in the pipeline near the tail of the hull, and the water flow is diverted by the water jet pump. The water flow pipeline is sucked in from the water inlet at the bottom of the hull, and then the water flow is sprayed out from the water outlet at the tail of the hull through the water jet pump, so as to obtain forward power and propel the ship forward. Because the water inlet and the water outlet are all arranged at the bottom of the hull, the water spraying speed is limited to a certain extent, so the energy consumption is relatively large.
