An underwater vehicle powered by compressed air

Abstract

The invention discloses an underwater vehicle capable of providing power on the basis of compressed air and belongs to the technical field of underwater vehicle design. The underwater vehicle capableof providing the power on the basis of the compressed air comprises a shell, a partition plate, an air storage tank, a servo control valve, a spray pipe assembly, an impeller, a transmission shaft anda propeller; the partition plate is arranged at the middle part of the interior of the shell and kept to be sealed together with the inner wall of the shell; high pressure air in the air storage tankis distributed to airflow nozzles, which are positioned on the other side of the partition plate and uniformly distributed in the circumferential direction, by the spray pipe assembly after passing through the servo control valve; the impeller, the transmission shaft and the propeller are arranged within the shell on the other side of the partition plate and immersed into the water; the impelleris mounted on the shell through a bracket; the impeller is connected with the propeller through the transmission shaft; a plurality of blades are uniformly arranged in the circumferential direction ofthe impeller; and the airflow nozzles are opposite to the blades; high pressure air in branch spray pipes blow the blades to drive the impeller to rotate so that the propeller is driven to rotate. According to the underwater vehicle capable of providing the power on the basis of the compressed air, a problem that the packing seal is easy to wear in the traditional mechanical transmission structure is solved, the service life is prolonged and the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicle design, and in particular relates to an underwater vehicle powered by compressed air. Background technique [0002] Frogmen are troops responsible for underwater reconnaissance, destruction and execution of special combat missions. Among them, the underwater movement ability of frogmen is an important factor affecting the efficiency of their task completion. At present, frogmen mostly use flippers and arms to carry out underwater sports. This form of human-powered movement has many limitations in terms of movement speed and voyage. There are also instances where frogmen use a one-man vehicle to increase their speed underwater. This type of underwater vehicle is in the form of a cylinder with batteries and motors inside, a propeller at the tail, and a handle on the shell. When in use, the diver pulls the handle to move with the propeller. [0003] The main problem of existing solutions...
