Embodiment Construction

[0032] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0033] Specific embodiment 1 of the manufacturing method of the lateral push grille of the present invention. The manufacturing method of the lateral push grille is to determine the specific parameters of the lateral push grille 2 according to the design parameters of the hull, and then make a product that matches the shape of the hull Push the grille 2. At the beginning of the ship design, in order to ensure the stability and sailing ability of the ship, the hull is usually designed to be wide at the top and narrow at the front and rear ends. Therefore, the hull plate 3 is in the horizontal direction at the bow and stern. There is a certain angle of inclination in the vertical direction. Such as figure 1 As s...

Abstract

The invention provides a side pushing grid manufacturing method, and relates to the technical field of ship side pushing devices. The side pushing grid manufacturing method comprises the following steps that firstly, the space position relation between a side pushing barrel and ship body outer boards is determined; secondly, in three-dimensional space of cartographic software, a cylinder and a plane figure corresponding to the position relation are drawn; thirdly, the cylinder is split according to the plane figure, and a split oval figure is obtained; and fourthly, a grid frame is manufactured according to the split oval figure. The split oval figure is utilized for conducting shape simulating on the grid frame, the grid frame is manufactured according to the split oval figure, the manufactured grid frame is matched with ports, in the positions of the ship body outer boards on the two sides, of the actual side pushing barrel in shape, parameters of the grid frame can be effectively determined according to the method, repeated testing and shape parameter adjusting are avoided, and the whole side pushing grid manufacturing process is more convenient and accurate.

Description

Technical field [0001] The invention relates to the technical field of ship side thrusters, in particular to a manufacturing method of a side thrust grating. Background technique [0002] The side thruster is the steering assist part of the ship. It is usually installed in the cylindrical structure of the bow or stern transversely penetrating the hull. The propeller of the side thruster rotates to discharge water from one side of the ship to the other side of the ship. The reaction force of the water on the propeller realizes the zero radius turning of the ship. In order to prevent plankton or garbage in the water from being sucked into the cylinder and entangled to damage the propeller, side push grilles are generally installed at the openings at both ends of the side push cylinder. [0003] For example, the Chinese utility model patent with authorized announcement number CN207208439U and authorized announcement number 2018.04.10 discloses a marine side push grille, and specifica...
