Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0022] In order to effectively reduce the structure noise caused by the vibration of the bow thruster in the operation process of the marine engineering ship, through analysis, calculation and model test, the present invention increases the installation height of the bow thruster, so that the supporting structure connected by the bow thruster is in the old The basic shape of the ship has been significantly enhanced, and the bell mouth structure is added to the water flow inlet of the bow thruster. At the same time, a ring connection structure is added in the height direction of the bow thruster and the deck, and the rib deck opening where the bow thruster is located is ca...

Abstract

The invention discloses an offshore ship bow thrust with a noise reduction function. The top of the bow thrust is connected to a deck via a connecting support body, wherein the connecting support body comprises a horizontal connecting frame and a plurality of longitudinal connecting support frames; the plurality of longitudinal connecting support frames are arranged in parallel at intervals along the width direction of the bow thrust; the horizontal connecting frame and the plurality of longitudinal connecting support frames are connected longitudinally so as to form a reinforced connecting support frame body capable of reducing noise; the bottom of the bow thrust is provided with a plurality of inner-narrow outer-wide trumpet-shaped water flow openings. The offshore ship bow thrust with the noise reduction function can be used for effectively lowering the structure noise caused by the vibration of the bow thrust in the running process.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a marine bow thruster with a noise reduction function. Background technique [0002] The bow thruster is the bow thruster, which is a special thruster installed at the bow of the ship, which is used to improve the maneuverability of the ship and can accurately maintain the ship's position. The bow thruster is used on offshore engineering ships and ferries. During operation, the bow thruster in the prior art often produces noise due to vibration. [0003] Therefore, it is necessary to further improve the structure of the bow thruster in the prior art to overcome the above-mentioned defects. Contents of the invention [0004] 1. Technical problems to be solved [0005] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and to provide a bow thruster with noise reduction function, which can effectively reduce the structural noise caused ...
