Abstract

The invention relates to a new type of water jet propulsion device, which includes a water inlet system and a water spray system. The front end is the water inlet, the shield is fixedly installed inside the water inlet conduit, the booster motor is fixedly installed in the shield, and connected to the turbocharger; the water spray system includes a connecting conduit and a guide ring, and the connecting conduit is used to communicate with the water inlet conduit With the diversion ring, the front end of the connecting conduit is connected with the rear end of the water inlet conduit, the rear end of the connecting conduit is fixedly connected with the front end of the diversion ring, and the water outlet of the connecting conduit is close to the inner wall of the front end of the diversion ring, and the rear end of the diversion ring The end is the ejection port. The device of the present invention utilizes the Coanda effect, and a guide ring is designed at the tail of the device to guide the ejected jet, eliminate the phenomenon of the jet spreading to the surroundings, make full use of the ejected jet, and generate thrust while changing the direction of the jet, so as to achieve more energy saving and environmental protection , Efficient new propulsion.

Description

technical field [0001] The invention relates to the technical field of marine propellers, in particular to a novel water jet propulsion device. Background technique [0002] A propeller is a device on a ship that generates kinetic energy. The propeller propeller is the most common type of propeller. The propeller is installed on the propulsion shaft below the waterline at the stern of the boat. The main engine drives the propulsion shaft to rotate together. The reaction force of the water propels the boat forward. [0003] In recent years, a new type of water jet propeller has emerged. The water jet propeller is a kind of propeller in which the jet part of the propulsion mechanism is immersed in water, and the reaction force generated by the jet water is used to drive the ship forward. It is composed of water pumps, pipes, suction ports and nozzles, etc., and can change the jetting direction of the water flow through the nozzles to realize the maneuvering of the ship. It ...
