Submersible propulsion

Abstract

A propelling device for a submersible comprises a frame, wherein the frame comprises a light housing and ends plates connected with the two ends of the frame. A propeller and a fixing structure are installed in the light housing, and the two end plates are respectively provided with a middle boss and a through-hole. The fixing structure comprises a rotating ring, two sides of the rotating ring are connected, the rotating ring is abutted against the end plates and is limited by limiting blocks on the end plates, and a first hold hoop tightly holds the propeller and is fixedly connected with the rotating ring. A steering mechanism comprises a rotary shaft of an encoder, the rotary shaft is driven by a driving device at a rotary shaft end, the rotary shaft penetrates the through-hole on the end plate and is fixedly connected with the end plate at the through hole through a rotating seat on the rotary shaft, a shaft shoulder of the rotating seat is fixedly connected with the end plate, the shaft end of the shaft shoulder is sequentially connected with a second hold hoop and a shaft sleeve, the second hold hoop holds the propeller tightly, and the shaft sleeve is sleeved on the middle boss and fixedly connected with the rotating ring. By the adoption of the propeller device capable of reversing, the propelling device for the submersible changes the traditional design that propeller devices are both arranged in the horizontal direction and in the vertical direction, reduces the quantity required of the propeller devices and reduces the cost.

Description

technical field [0001] The invention relates to the technical field of submersible propulsion, in particular to a propulsion device capable of reversing between a horizontal direction and a vertical direction. Background technique [0002] Submersibles refer to underwater platforms with underwater detection and operation capabilities. They are mainly used to perform tasks such as underwater surveys, seabed exploration, seabed development and salvage. They are widely used in the research of marine basic disciplines and the investigation and development of marine resources. field. In order to complete a series of underwater tasks such as scientific investigations, the submersible is required to have certain underwater navigation motion and anti-flow dynamic positioning control capabilities, and to realize this multi-degree-of-freedom manipulation and control function in the horizontal and vertical planes, The submersible needs to be equipped with multiple sets of lateral and ...
