KR-102964678-B1 - the radome insert rings

Abstract

The present invention relates to an insert ring used in a radome for a submarine. The insert ring used in the submarine radome of the present invention comprises: a first insert plate having a square box shape with an arc shape, one end forming a half-lap joint, and the other end forming a protrusion; a second insert plate having a square box shape with an arc shape, one end forming a half-lap joint, and the other end forming a protrusion, installed symmetrically with respect to the first insert plate; and a third insert plate having a square box shape with an arc shape, installed by forming grooves on both left and right ends corresponding to the protrusions of the first and second insert plates. The present invention provides an insert ring used in a submarine radome with excellent airtightness, wherein the insert ring, which is secondarily molded integrally with the radome cap, is divided into three sections and inserted into the radome cap, thereby preventing internal damage to the radome cap made of FRP material during the second molding process, as well as ensuring that the radome cap and the body are firmly sealed against each other.

Description

Insert rings used in submarine radomes. The present invention relates to an insert ring used in a submarine radome, and more specifically, to an insert ring used in a submarine radome in which the insert ring, which is secondarily molded integrally with the radome cap, is divided into three sections and inserted into the radome cap, thereby preventing internal damage to the radome cap made of FRP material during the second molding, as well as ensuring that the radome cap and the body are firmly sealed against each other and having excellent airtightness. Generally, a radome is a compound word of radar and dome. Radar is a device that detects aircraft, obstacles, or other targets by fixing or rotating (called scanning) an antenna with a parabolic shape and emitting and capturing high-frequency directional radio waves into space. These radomes consist of a cap, a cap bracket, and a body to protect against external environmental factors such as weather conditions like wind, rain, salt, and humidity, as well as physical impact. Since they are typically made entirely of plastic, extensive research has been conducted to enhance their durability, airtightness, and sealing capabilities. For example, Korean Registered Patent Publication No. 10-1334670 discloses a radome comprising: a base that supports a tracking antenna on a bottom surface and has a plurality of support ledges formed along the inner circumference of an upper opening, wherein the support ledges have through holes formed therein so that they can be screwed from the bottom to the top; a dome that has an opening at the bottom to cover the tracking antenna; a lower coupler that is screw-coupled to the inner circumference of the base while resting on the support ledges of the base and has either a fitting projection or a fitting groove formed on its upper surface; and an upper coupler that is screw-coupled to the inner circumference of the opening of the dome, has a plurality of seating bosses formed on its lower surface having screw holes so as to be placed on the support ledges and coupled with the support ledges, and has either a fitting groove or a fitting projection formed to correspond to the fitting projection of the lower coupler. However, the above technology has a problem in that its components are made of the same material, resulting in poor durability and airtightness, making it unsuitable for use in submarines requiring high underwater pressure. FIG. 1 is a plan view of an insert ring used in a submarine radome of the present invention. FIG. 2 is an exploded view of an insert ring used in a submarine radome of the present invention. FIG. 3 is a bottom view of an insert ring used in a submarine radome of the present invention. The insert ring used in the submarine radome of the present invention is configured such that the insert ring, which is secondarily molded integrally with the radome cap, is divided into three sections and inserted into the radome cap, thereby preventing internal damage to the radome cap made of FRP material during the second molding, as well as ensuring that the radome cap and the body are firmly sealed against each other and have excellent airtightness. In this application, terms such as "comprising" or "consisting of" are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not excluding in advance the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which this invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a plan view of an insert ring used in a submarine radome of the present invention, FIG. 2 is an exploded view of an insert ring used in a submarine radome of the present invention, and FIG. 3 is a bottom view of an insert ring used in a submarine radome of the present invention. As shown in FIGS. 1 to 3, the insert ring used in the submarine radome of the present invention comprises a first insert plate (10), a second insert plate (20), and a third insert plate (30). The first insert plate (10) is formed in the shape of a square box with an arc shape, and is structured such that one end forms a half-lap portion (11) and the other end forms a protrusion portion (13). The first insert plate (10) has a structure that is fitted onto the inner surface of a radome ca
