Design method of integrated mounting base of underwater sensor of navigation equipment

Abstract

The invention discloses a design method of an integrated base of an underwater sensor of navigation equipment. The design method specifically comprises the following steps: determining the inner diameter of a mounting base according to the size of the underwater sensor; determining the height and the outer diameter of the mounting base according to the size of the watertight valve, the included angle between the outer plate and the horizontal plane at the mounting position and the thickness of the outer plate; setting an included angle between the flow guide cover and the outer plate; determining the radius of the air guide sleeve according to the included angle between the air guide sleeve and the outer plate, the included angle between the outer plate and the horizontal plane and the height and outer diameter of the mounting base; performing three-dimensional modeling on the mounting base and the air guide sleeve; and according to the three-dimensional model of the mounting base andthe fairing, forming an integrated base mold, and producing the integrated base. According to the invention, the problem that the normal work of the underwater sensor is influenced because fragments are generated around the underwater sensor of the navigation equipment due to poor welding quality of a welding seam between the existing mounting base and the air guide sleeve is effectively solved while the mounting process is reduced.

Description

Technical field [0001] The invention relates to the technical field of ship construction, in particular to a method for designing an integrated installation base of an underwater sensor of a navigation device. Background technique [0002] Underwater sensors for navigation equipment such as electromagnetic log, differential pressure log, Doppler log and depth sounder must be installed on the bottom of the ship. During the installation process, it is necessary to ensure that the detection plane of the underwater sensor of the navigation equipment is level. Because the bottom line of the ship is not always horizontal, but the closer it is to the ship, the greater the inclination, as well as the limitation of cabin layout space, the navigation equipment underwater sensor equipment often cannot be arranged and installed in the ship’s position, resulting in the installation base The seat protrudes from the bottom of the ship. [0003] When a ship is traveling at high speed, the air wi...

Problems solved by technology

This set of installation process is too complicated. If the grinding is not smooth, debris will be generated around the underwater sensor of the navigation equipment during the high-speed driving of the ship, which will affect the normal operation of the underwater sensor.
