Description

[Detailed description of the invention] The present invention relates to a protection device for a sonar transducer.
More specifically, the present invention relates to an improvement in a protection device attached to the bottom of a ship surrounding a sonar transducer provided on the bottom of the ship.

In the first place, the protection device for sonar transducers is
As shown in the figure, for the purpose of protecting the sonar transducer F attached to the bottom Sa of the ship S, it is attached to the bottom Sa to cover it, and its structure is It consists of a protective cover mounting body 100 that surrounds the sonar transducer F and is attached to the bottom Sa of the ship, and a protective cover body 200 that is detachably attached to the protective cover mounting body 100.

However, conventionally, in order to reinforce the bead provided at the periphery of the opening of the protective cover main body 200, the bead wire buried in the bead is formed into an endless ring shape by joining its ends together. , as shown in an enlarged explanatory view of the joint portion in FIG.
Alternatively, as shown in FIG. 3, the ends of the bead wire 221 are loosened, and the loosened ends are knitted together to join and integrate.

However, in the case of joining using the socket T described above, a step corresponding to the width of the socket T is created at the joint, and even when joined by weaving the loosened ends together, the joint is not connected to other parts. Not only does it become impossible to obtain a bead wire with a constant cross section over the entire circumference, but also the flexibility of the joint between the two ends is significantly reduced compared to other parts.

As a result, it is not possible to obtain a bead portion with uniform flexibility in a constant cross section, and when the protective cover main body 200 is attached to the protective cover mounting body 100 through this bead portion, problems such as watertightness cannot be obtained. It was hot.

The present invention was developed as a result of studies to solve the above-mentioned problems.

Therefore, the purpose of this invention is to make the cross-sectional shape and flexibility of the bead part uniform by devising the bonding structure of the bead wire embedded in the protective cover body, especially the bead part, and to achieve sonar wave transmission and reception with excellent watertightness. The aim is to provide dexterity protection equipment.

In other words, the present invention consists of a protective cover mounting body that surrounds the sonar transducer installed on the bottom of the ship and is attached to the bottom of the ship, and a protective cover body that is removably attached to the protective cover mounting body. The main body includes a protective cover made of a rubber-like elastic material with a reinforcing layer embedded in it, which has a streamlined longitudinal profile and an approximately semicircular cross-sectional shape, and is positioned around the opening of the protective cover. and a bead part which is integrally attached and has a bead wire embedded therein, and the bead wire is composed of a core strand and side strands wound around the core strand tightly and without overlapping each other, The ends of the core strands are butted against each other and joined to form a ring shape, the outer diameter of this butted joint is substantially the same as the outer diameter of the core strand itself, and the ends of the side strands are joined together. The gist of the present invention is to provide a protection device for a sonar transducer, characterized in that the core strands are butt-joined at positions that do not overlap with the joint portions of the core strands.

Hereinafter, the present invention will be explained in detail by way of examples with reference to the drawings.

FIGS. 4 to 9 each show a protection device for a sonar transducer according to an embodiment of the present invention.
FIG. 4 is a plan view explanatory diagram of the bead wire buried in the bead portion, FIG. 5 is an enlarged cross-sectional view taken from FIG. FIG. 7 is a perspective explanatory view of the protective cover body, FIG. 8 is an enlarged cross-sectional view of FIG.
FIG. 9 is an enlarged cross-sectional view, partially cut away, showing a state in which the protective cover body is attached to the protective cover attachment body.

In the figure, E indicates a protection device for a sonar transducer according to an embodiment of the present invention, which is composed of a protective cover mounting body 100 and a protective cover body 200 detachably attached to the protective cover mounting body 100. ing.

In the present invention, the protective cover body 200
The protective cover 210 is made of a rubber-like elastic body in which a reinforcing layer K is embedded, and the outer shape in the longitudinal direction is streamlined and the cross-sectional shape is approximately semicircular.
The bead portion 220 is integrally attached to the periphery of the opening of 0 and has a bead wire 221 embedded therein.

Moreover, in the present invention, the bead wire 221
In particular, it is composed of a core strand 222 and side strands 223 wound around the core strand 222 tightly and without overlapping each other, as shown in FIG. The end portions a and a are butted and joined to form a ring shape, and the outer diameter of this butted joint portion A and the outer diameter of the core strand 222 are made to be substantially the same size, and the side strand The ends b and b of the side strands 223 are similarly butted and joined, and the joint part B of this side strand 223 is provided at a position that does not overlap the joint part A of the core strand 222.

To further explain this structure in detail, the protective cover mounting body 100 includes an inner mold 110 that surrounds the sonar transducer F provided on the ship's bottom Sa and is attached to the ship's bottom, and an inner mold 110 that can be attached to and detached from the outside of the inner mold 110. The inner mold 110 has a fitting recess 111 for the bead portion 220 on its outer peripheral surface.
are continuously provided, and the outer mold 120 has a bead fitting recess 11 of the inner mold 110 on its inner peripheral surface.
A bead portion fitting recess 121 is provided corresponding to 1.

The protective cover body 2 is attached to this protective cover mounting body 100.
00, first install the protective cover mounting body 10.
After the bead portion 220 of the protective cover body 200 is fitted into the bead portion fitting recess 111 of the inner mold 110 of No. 0, a plurality of outer molds 120 are respectively attached to the outside thereof with bolts 130. (See FIG. 9) In the figure, 224 indicates the protective cover main body 20.
Protective cover 210 and bead portion 220 constituting 0
It is an outer layer of rubber that completely covers the outer surface of the

As described above, the present invention has a structure of a bead wire, in particular, consisting of a core strand and side strands wound around the core strand tightly and without overlapping each other, and in addition, the end of the core strand The ends of the side strands are butted together so that the outside diameter of the joint is substantially the same as the outside diameter of the core strand itself, and the ends of the side strands are butted together in a position that does not overlap with the joint of the core strand. The following effects can be achieved by joining them together. (1) Since the bead wire is constructed by winding the side strands tightly around the core strand without overlapping each other, the compressive strength of the bead wire itself can be improved, and the It is possible to improve the flexibility and prevent the buried bead portion from losing its shape, and it is also possible to mold the bead portion into a desired shape, especially when viewed from one side.

(2) Moreover, the core strands are joined by butting their ends together to form a ring shape, and the ends of the side strands are located at positions that do not overlap with the joints of the core strands, Since the bead wire is butted and joined, the cross-sectional shape and flexibility of the bead wire can be made uniform over the entire circumference. When the protective cover main body is attached to the protective cover mounting body through the bead portion, high watertightness can be obtained.
