Description

[0001]
[Industrial applications]
The present invention relates to a structure of a transducer protection device and a method of manufacturing the transducer protection device, and more particularly, to a transducer (acoustic sensor) installed in a cavity formed in a lower portion of a bow of an observation ship or the like. The present invention relates to a structure of a transducer protector constituting a sonar dome body made of rubber which effectively protects the apparatus from noise generated from the ship or the like, and a method of manufacturing the transducer protector.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a rubber sonar dome for protecting a transducer (acoustic sensor) mounted on an observation ship or the like is mounted on a ship bottom to improve acoustic performance, that is, a so-called keel dome type is mounted on a bow. It is changing to a bow-dome type. That is, in order to reduce the effects of engine noise and vibration generated from the ship itself and other equipment and underwater noise generated from the propeller, the hull 1 is likely to be mounted on the bow 2 side of the hull 1 as shown in FIGS. It is in.
[0003]
In this manner, the dome main body 5 having a small sound transmission loss largely protrudes forward to the bow 2 side with the tendency to attach the rubber sonar dome 4 for protecting the transducer 3 to the bow 2 side. There is no defense against the generated noise Q.
[0004]
[Problems to be solved by the invention]
By the way, there is also a method of attaching a tile-shaped sound insulating material 6 to the inside of the dome body 5 as shown in FIG. 4 for the noise Q generated from the hull 1 and entering the transducer 3 as shown in FIG. However, it is difficult to affix the sound insulating material 6 in accordance with the curvature R of the dome main body 5, and the workability is poor. In addition, there is a possibility that the attached sound insulating material 6 may be peeled off in a short time, so there is room for improvement. was there.
[0005]
The present invention has been devised in view of such conventional problems, and a sound insulating material can be easily applied to a dome body portion, and there is no problem of peeling off in a short time, and the sound insulating performance and durability are improved. An object of the present invention is to provide an excellent structure of a transducer protector and a method of manufacturing the transducer protector .
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a structure of a transducer protector according to the present invention, wherein a sonar dome body includes an inner rubber layer having a reinforcing layer embedded therein, and an outer rubber layer disposed with a thickness adjusting rubber therebetween. The gist is that a rubber tiled sound insulating material is integrally embedded in the rubber sonar dome body at the time of vulcanization molding in a thick rubber portion other than the measurement range of the transducer. It is to be.
[0007]
Further, the method for manufacturing a transducer protector according to the present invention is characterized in that the inner layer rubber made of antifouling rubber having a reinforcing layer embedded therein and the outer rubber layer made of antifouling rubber disposed with a thickness adjusting rubber interposed therebetween have a sonar. A method for manufacturing a transducer protector constituting a dome body, wherein a sound insulating material formed in a tile shape in advance is embedded in the thickness adjusting rubber in a portion other than the measurement range of the transducer, and the sonar dome body is The gist of the invention is that molding is performed integrally during vulcanization molding.
[0008]
Effect of the Invention
The present invention is configured as described above, and forms a sound insulation material that reflects noise coming from the hull and reduces noise in the sonar dome in the form of a rubber tile. When the dome body is manufactured, that is, the sound insulation material is disposed on the inner layer rubber of the part other than the measurement range of the transducer, and it is embedded and molded at the time of vulcanization. Can be solved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
The same components as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted.
FIG. 1 is a partially enlarged cross-sectional view of a transducer protector 10 embodying the present invention. A transducer 12 is installed in a cavity 11 formed at a lower part on the bow 2 side. A sonar dome body 14 made of rubber and having a sound insulating material 13 formed in a rubber tile shape so as to cover it is attached to the hull.
[0010]
The sonar dome main body 14 is composed of an inner rubber layer 16 made of antifouling rubber in which a reinforcing layer 15 in which wires and the like are bundled is embedded, and an outer rubber layer 18 made of antifouling rubber provided with a thickness adjusting rubber 17 interposed therebetween. The beat portion 15a at the terminal portion of the reinforcing layer 15 is fixed to the metal fitting 1 to the hull using a clamp 1a.
The tile-shaped sound insulating material 13 is embedded in the thickness adjusting rubber 17 of the portion Z other than the measuring range X of the transducer 12, and the sound insulating material 13 is other than the measuring range X of the transducer 12. Is arranged at the thicker thickness adjusting rubber portion 17 at the thicker portion, and is integrally molded at the time of vulcanization.
[0011]
As described above, the sound insulating material 13 formed in a rubber tile shape is disposed in advance in the thickness adjusting rubber 17 of the portion Z other than the measurement range X of the transducer 12 when the sonar dome body 14 is formed. By integrally forming during vulcanization molding, it is possible to omit the work of pasting, and it does not peel off during use and has good durability.
Further, since the sound insulating material 13 is embedded in the thickness adjusting rubber 17, it is possible to ensure the smoothness of the surface.
[0012]
【The invention's effect】
The present invention embeds a sound insulation material formed in a tile shape in advance in the thickness adjusting rubber in a portion other than the measurement range of the transducer as described above, and integrally molds the sonar dome body during vulcanization molding. Therefore, the sound insulation material can be easily applied to the dome body, the workability can be improved, and there is no problem of peeling in a short time, and the sound insulation performance and durability are excellent. There is an effect that can be.
