Supporting structure of propulsion motor used by manned submersible

Abstract

A supporting structure of a propulsion motor used by a manned submersible comprises a steel channel and a supporting leg type support, wherein the supporting leg type support is fixedly connected with the inner wall of the steel channel and is in a bisection structure, a left half body of the supporting leg type support and a right half body of the supporting leg type support are fixedly connected to form an X-shaped supporting structure which is installed inside the steel channel, a groove is arranged on the inner wall of the steel channel, a supporting leg of the supporting leg type support is installed inside the groove, a stopping block is installed inside the groove and is fixedly connected with the steel channel, and the stopping block is closely attached to and connected with the supporting leg of the supporting leg type support, so that the axial positioning method of a shaft shoulder at one end of the supporting leg type support and the stopping block at the other end of the supporting leg type support is formed. By the aid of the supporting structure, the coaxial requirements for assembly of the propulsion motor with a propeller and the steel channel can be met, simultaneously, the deformation-resistant ability of the whole supporting structure can be improved, and the working is reliable.

Description

technical field [0001] The invention relates to a propeller for a manned submersible, in particular to a channel auxiliary propeller for a manned submersible, and in particular to a supporting structure for a propulsion motor in the propeller. Background technique [0002] Manned submersibles carry scientists and engineers into the deep sea to effectively perform marine scientific investigations and other related underwater operations. In order to complete the series of scientific investigations and other underwater operations, the manned submersible is required to have a certain ability to adjust the underwater attitude, and on the basis of setting the main propeller on the manned submersible, the The horizontal and vertical slot propellers can better meet the attitude adjustment requirements of the manned submersible for floating, diving, moving left, and moving right under water. In order to ensure the efficiency of propulsion and the service life of the propulsion motor...

AI Technical Summary

Problems solved by technology

[0003] At present, the structure used to support the propulsion motor in the upper channel thruster of the manned submersible is as follows: figure 1 and figure 2 As shown, it includes a steel channel 101 pre-assembled on the structural frame of the submersible, a leg-type bracket 102 welded in the steel channel 101, and a hoop 103 matched with the outrigger-type bracket 102, and a propeller 104 is assembled. The propulsion motor 105 is installed on the outrigger type bracket 102 through the hoop 103. Although the support structure can fix the propulsion motor and the propeller in the channel, it has the following disadvantages: on the one hand, because the channel wall is generally relatively It is thin, and it is easy to cause deformation of the processed channel during the welding process with the outrigger bracket, so it is difficult to ensure the coaxiality requirements for the assembly between the propulsion motor equipped with the propeller and the steel channel. At the same time, the outrigger bracket The weld with the steel channel is likely to cause stress concentration, which will cause deformation of the steel channel. When the propulsion motor is running at full load or overloaded, the gap between the propeller and the channel will be reduced, causing the propeller to rotate During the process, the inner wall of the channel is scratched, causing damage to the propeller; on the other hand, because the gap between the propeller and the steel channel is generally small, after the propulsion motor is started, the propeller is driven to transmit the thrust to the outrigger bracket, which will cause damage to the propeller. A bending moment is generated on the outrigger bracket, resulting in the deformation of the outrigger bracket and the steel channel, which causes the axis of the propulsion motor to deviate from the axis of the steel channel
