Problems solved by technology

Because the propeller is used as power, the noise generated by ships and warships is large, and it is difficult to increase their navigation speed, and because the propeller is placed underwater, it is easy to be damaged by underwater aquatic plants or old fishing nets. things tied up, causing trouble to the navigation of ships and warships

Embodiment Construction

[0010] Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing

[0011] figure 1 Among them, the outer tube 5 is made of a straight tube and a large conical tube 7 connected at one end thereof, and a constricted conical tube 2 connected at the other end. Inner tube 3 is housed in outer tube 5, and inner tube 3 is connected with the outer tube 11 of small cone tube 9 by one end, and central tube 12 is set in the outer tube 11, and one end of central tube 12 and the small cone on the outer tube 11 The tubes 9 are connected and formed by fixedly connecting three uniformly distributed front support plates 4 with the inner cavity wall at the other end of the outer tube 11 . And the other end of the central tube 12 is connected with the shrinkage cone tube 2 at one end of the outer tube 5, and the outer tube 11 is fixedly connected with the inner cavity wall at one end of the outer tube 5 through three evenly distributed re...

Abstract

A water-spraying thruster for ship or submarine is composed of an internal pipe, an external pipe, a fluid cavity between said internal and external pipes and with a conic head, a spray tube on said external pipe and a central water inlet tube, which are communicated with said fluid cavity, and a motor driven water pump connected to said water inlet tube. When water is sprayed out of the spray tube a huge push force is generated.

Description

technical field [0001] The invention relates to a ship propulsion device, especially a water jet thruster, which is suitable for ships, ships and submarines in the defense industry. Background technique [0002] At present, ships and warships sailing in water mostly adopt propellers as power to push forward. Because the propeller is used as power, the noise generated by ships and warships is large, and it is difficult to increase their navigation speed, and because the propeller is placed underwater, it is easy to be damaged by underwater aquatic plants or old fishing nets. Things are tied up, which brings trouble to the navigation of ships and warships. Contents of the invention [0003] The purpose of the present invention is to provide a water jet thruster, which can overcome the deficiencies of the existing technology, not only can avoid being tied up by underwater sundries, but also has low noise, and can effect...
