Underwater vehicle thrust by hydrogen produced through sodium borohydride hydrolysis

Abstract

The invention relates to a device for underwater carrying at a high speed, and aims to provide an underwater vehicle thrust by hydrogen produced through sodium borohydride hydrolysis. A propulsion system of the underwater vehicle comprises a water inlet arranged at a head of a ship body, an air spraying tube arranged at a tail part of the ship body, a sodium borohydride container and a tapered reactor, wherein the water inlet is a pipeline partly extending to the front end of the sodium borohydride container; a pipe wall of the pipeline extending into the container is provided with a small hole; a back part of the sodium borohydride container is a filter screen; a front end of the tapered reactor is connected to a back part of the sodium borohydride container by a clapboard provided with a plurality of through holes; the back part of the tapered reactor is connected to the air spraying tube by a pipeline; sodium borohydride powders are filled in the sodium borohydride container; and the tapered reactor is filled with a multi-hole three-dimensional catalyst. The speed for producing hydrogen through sodium borohydride hydrolysis is fast, so that the underwater vehicle obtains a high accelerated speed; combustion is not needed; the control is easy; and the propulsion speed is high. Wide application prospects in marine science survey, sea bottom survey, sea bottom cable detection and the like are provided.

Description

technical field [0001] The invention relates to a device for underwater high-speed transportation, more specifically, the invention relates to an underwater vehicle that uses sodium borohydride to hydrolyze hydrogen to produce hydrogen and generate powerful thrust through an injector to travel at high speed. Background technique [0002] In the ocean, whether it is a ship sailing on the surface or an underwater submarine, it basically adopts the propeller propulsion method. The propeller is directly driven by the engine through the propulsion shaft. When the propeller rotates, the water flow is pushed to the rear of the vehicle. According to the principle of action and reaction, water produces a reaction force on the propeller, which is called the thrust of the propeller. However, just like the development of aircraft in human history, due to the relatively weak thrust generated by the propeller, the speed of the propeller aircraft is relatively slow. In jet aircraft, due t...
