Description

本発明は、船舶に送受波器を取り付けるための取付構造、及び取付部材に関するものである。   The present invention relates to an attachment structure for attaching a transducer to a ship, and an attachment member.

水中内の魚群を探知することなどを目的として、魚群探知機などの水中探知装置が広く使用されている。この水中探知装置は、船舶などに設置されており、送受波器によって、水中に超音波の送信ビームを送信した後、魚群などの物標によって反射したエコーを受信する。そして、水中探知装置は、受信したエコーに対して各種処理を実行することで、魚群などの水中の情報に関する画像を形成し、表示装置にその画像を表示する。   Underwater detection devices such as a fish finder are widely used for the purpose of detecting a school of fish in the water. This underwater detection apparatus is installed in a ship or the like, and after transmitting an ultrasonic transmission beam underwater by a transducer, receives an echo reflected by a target such as a school of fish. Then, the underwater detection device performs various processes on the received echo to form an image related to underwater information such as a school of fish, and displays the image on the display device.

送受波器は、通常、船舶の船底に取り付けられる。この送受波器の取付方法としては、インナーハル方式と呼ばれる取付方法と、スルーハル方式と呼ばれる取付方法とがある。まず、インナーハル方式について説明すると、インナーハル方式では、例えば特許文献１の図２に示されるように、船底の内側にケースを取り付ける。そして、ケース内を水などの液体によって充填し、超音波振動子を有する送受波器をケース内に保持する。このようなインナーハル方式では、送受波器を船底に手軽に設置することができる一方で、送受波器は船底板を介して超音波の送受信を行うために、超音波の送受信感度が良好ではないという欠点がある。   The transducer is usually attached to the bottom of a ship. As a method for attaching the transducer, there are an attachment method called an inner hull method and an attachment method called a through hull method. First, the inner hull method will be described. In the inner hull method, for example, as shown in FIG. Then, the case is filled with a liquid such as water, and the transducer having the ultrasonic transducer is held in the case. In such an inner hull method, the transmitter / receiver can be easily installed on the bottom of the ship, while the transmitter / receiver transmits / receives an ultrasonic wave through the bottom plate of the ship. There is a disadvantage of not.

これに対して、スルーハル方式では、船底に貫通孔を形成し、送受波器の超音波を送受信する送受信面を貫通孔から外部に露出させるように、送受波器を船底に設置する。これにより、送受波器は、船底板を介在させずに水中内に超音波を直接送信できるとともに、そのエコーを直接受信することができる。このため、スルーハル方式は、インナーハル方式よりも送受波器における超音波の送受信感度が良好であるというメリットがある。   In contrast, in the through-hull method, a through-hole is formed in the bottom of the ship, and the transmitter / receiver is installed on the bottom of the ship so that the transmitting / receiving surface for transmitting / receiving ultrasonic waves from the transmitter / receiver is exposed to the outside from the through-hole. Thereby, the transducer can directly transmit the ultrasonic wave into the water without interposing the ship bottom plate, and can directly receive the echo. For this reason, the through-hull method has an advantage that the ultrasonic wave transmission / reception sensitivity in the transducer is better than the inner hull method.

特開２００７−２８５７３０号公報JP 2007-285730 A

ところで、スルーハル方式によって送受波器を船底に取り付ける際、船底に貫通孔を形成する必要がある。このため、送受波器の取付作業が不適切であると、貫通孔を介して船体内に水が侵入してくるおそれがある。したがって、従来のスルーハル方式では、船体内への浸水を防ぐよう送受波器の取付作業を慎重に行う必要があり、送受波器の取付作業に時間及び手間が掛かるという問題がある。   By the way, when the transducer is attached to the ship bottom by the through hull method, it is necessary to form a through hole in the ship bottom. For this reason, if the mounting operation of the transducer is inappropriate, water may enter the ship body through the through hole. Therefore, in the conventional through-hull method, it is necessary to carefully install the transducer to prevent water intrusion into the hull, and there is a problem that it takes time and effort to install the transducer.

そこで、本発明は、良好な送受信感度を維持しつつ船舶に対する送受波器の取付作業の作業時間及び手間を軽減することのできる送受信装置の取付構造及び取付部材を提供することを課題とする。   Then, this invention makes it a subject to provide the attachment structure and attachment member of the transmission / reception apparatus which can reduce the work time and labor of attachment work of the transducer with respect to a ship, maintaining favorable transmission / reception sensitivity.

First, a ship to which an underwater detection device is attached will be described with reference to the drawings. FIG. 1 is a side sectional view showing a ship 10 to which an underwater detection device 11 is attached.

In the following description, “upper” and “lower” are aligned with the vertical direction in FIG.

図２及び図３に示すように、本実施形態に係る取付構造１は、生け簀１４に送受波器１２を取り付けるための取付構造であって、ガイド部材２と、固定部材３と、取付部材４と、を備えている。以下、各部材についての詳細を説明する。   As shown in FIGS. 2 and 3, the attachment structure 1 according to this embodiment is an attachment structure for attaching the transducer 12 to the sacrifice 14, and includes a guide member 2, a fixing member 3, and an attachment member 4. And. Details of each member will be described below.

［ガイド部材］
ガイド部材２は、固定部材３と協働して船底板１５を挟み込むことによって、船底板１５に固定されている。このガイド部材２は、円筒状のガイド部材本体２１と、フランジ部２２と、突出部２３と、を備えている。なお、ガイド部材本体２１と、フランジ部２２と突出部２３とは、一体的に形成されている。 [Guide member]
The guide member 2 is fixed to the bottom plate 15 by sandwiching the bottom plate 15 in cooperation with the fixing member 3. The guide member 2 includes a cylindrical guide member main body 21, a flange portion 22, and a protruding portion 23. In addition, the guide member main body 21, the flange part 22, and the protrusion part 23 are integrally formed.

ガイド部材本体２１は、生け簀１４の底面を画定する船底板１５に形成された貫通孔１６の内壁面に沿って延びるように筒状に形成された部分である。すなわち、ガイド部材本体２１は、船底板１５の貫通孔１６に嵌るような円筒状であって、その外径が貫通孔１６の内径とほぼ合致するように設計されている。ガイド部材本体２１は、外壁面に雄ネジ部が形成されており、内壁面に雌ネジ部が形成されている。また、ガイド部材本体２１の上端部には、内側に向かって傾斜する傾斜面が形成されており、この傾斜面と取付部材４との間で、弾性部材であるＯリング１００を押圧している。なお、この傾斜面を形成せずに、ガイド部材本体２１の上端面を平坦に形成し、この平坦な上端面と取付部材４のフランジ部４２との間でＯリング１００を押圧してもよい。   The guide member main body 21 is a portion formed in a cylindrical shape so as to extend along the inner wall surface of the through hole 16 formed in the ship bottom plate 15 that defines the bottom surface of the sacrifice 14. That is, the guide member main body 21 has a cylindrical shape that fits into the through hole 16 of the ship bottom plate 15, and is designed so that its outer diameter substantially matches the inner diameter of the through hole 16. The guide member main body 21 has a male screw portion formed on the outer wall surface and a female screw portion formed on the inner wall surface. In addition, an inclined surface that is inclined inward is formed at the upper end of the guide member main body 21, and the O-ring 100 that is an elastic member is pressed between the inclined surface and the attachment member 4. . Instead of forming the inclined surface, the upper end surface of the guide member main body 21 may be formed flat and the O-ring 100 may be pressed between the flat upper end surface and the flange portion 42 of the mounting member 4. .

フランジ部２２は、ガイド部材本体２１の外壁面における下端部に形成されている。フランジ部２２は、ガイド部材本体２１の外壁面から外方に向かって延びている。また、ガイド部材２を船底板１５に固定した状態において、フランジ部２２は、その上面が船底板１５の下面、すなわち船底と当接している。また、フランジ部２２の下面は、外方にいくにしたがってフランジ部２２の厚さが薄くなるように傾斜している。このようにフランジ部２２の下面が傾斜することによって、フランジ部２２と船底板１５との境界部分における段差を小さくしている。   The flange portion 22 is formed at the lower end portion of the outer wall surface of the guide member main body 21. The flange portion 22 extends outward from the outer wall surface of the guide member main body 21. Further, in a state where the guide member 2 is fixed to the ship bottom plate 15, the upper surface of the flange portion 22 is in contact with the lower surface of the ship bottom plate 15, that is, the ship bottom. Further, the lower surface of the flange portion 22 is inclined so that the thickness of the flange portion 22 becomes thinner as going outward. In this way, the lower surface of the flange portion 22 is inclined, thereby reducing the step at the boundary portion between the flange portion 22 and the ship bottom plate 15.

突出部２３は、ガイド部材本体２１の内壁面における下端部に形成されている。突出部２３は、ガイド部材本体２１の内壁面から内方に向かって突出している。また、突出部２３は、環状に形成されている。すなわち、突出部２３は、ガイド部材本体２１の内壁面の周方向に沿って形成されている。   The protrusion 23 is formed at the lower end of the inner wall surface of the guide member main body 21. The protruding portion 23 protrudes inward from the inner wall surface of the guide member main body 21. Moreover, the protrusion part 23 is formed in the cyclic | annular form. That is, the protrusion 23 is formed along the circumferential direction of the inner wall surface of the guide member main body 21.

［固定部材］
固定部材３は、上述したガイド部材２を船底板１５に固定するための部材であって、円筒部３１と、フランジ部３２とを備えている。なお、円筒部３１とフランジ部３２とは一体的に形成されている。 [Fixing member]
The fixing member 3 is a member for fixing the above-described guide member 2 to the ship bottom plate 15, and includes a cylindrical portion 31 and a flange portion 32. The cylindrical portion 31 and the flange portion 32 are integrally formed.

円筒部３１は、円筒状であって、その内径がガイド部材２のガイド部材本体２１の外径とほぼ合致するように設計されている。また、円筒部３１の内壁面には雌ネジ部が形成されている。この円筒部３１の内壁面に形成された雌ネジ部は、ガイド部材本体２１の外壁面に形成された雄ネジ部と螺合する。   The cylindrical portion 31 has a cylindrical shape and is designed so that its inner diameter substantially matches the outer diameter of the guide member main body 21 of the guide member 2. An internal thread portion is formed on the inner wall surface of the cylindrical portion 31. The female screw portion formed on the inner wall surface of the cylindrical portion 31 is screwed with the male screw portion formed on the outer wall surface of the guide member main body 21.

固定部材３のフランジ部３２は、円筒部３１の外壁面における下端部に形成されている。フランジ部３２は、円筒部３１の外壁面から外方に向かって延びている。固定部材３によってガイド部材２を船底板１５に固定した状態において、フランジ部３２の下面が、船底板１５の上面、すなわち船底板１５の生け簀１４側の面と当接している。この固定部材３のフランジ部３２と、ガイド部材２のフランジ部２２とによって、船底板１５を挟み込むことによって、ガイド部材２を船底板１５に固定している。   The flange portion 32 of the fixing member 3 is formed at the lower end portion of the outer wall surface of the cylindrical portion 31. The flange portion 32 extends outward from the outer wall surface of the cylindrical portion 31. In a state where the guide member 2 is fixed to the ship bottom plate 15 by the fixing member 3, the lower surface of the flange portion 32 is in contact with the upper surface of the ship bottom plate 15, that is, the surface of the ship bottom plate 15 on the sacrifice 14 side. The guide member 2 is fixed to the bottom plate 15 by sandwiching the bottom plate 15 between the flange portion 32 of the fixing member 3 and the flange portion 22 of the guide member 2.

［取付部材］
取付部材４は、送受波器１２をガイド部材２に取り付けるための部材である。取付部材４は、取付部材本体４１と、フランジ部４２とを備えている。なお、取付部材本体４１とフランジ部４２とは一体的に形成されている。 [Mounting member]
The attachment member 4 is a member for attaching the transducer 12 to the guide member 2. The attachment member 4 includes an attachment member main body 41 and a flange portion 42. The attachment member main body 41 and the flange portion 42 are integrally formed.

ここで、取付部材４に固定される送受波器１２について簡単に説明する。まず、送受波器１２は、振動子を内蔵する送受波部１２１と、送受波部１２１の上面から上方に延びる軸部１２２とを備えている。送受波部１２１は円柱状に形成されており、送受波部１２１の下面は、超音波を送受信する送受信面１２１１になっている。軸部１２２は、送受波部１２１よりも小さい外径を有する円柱状であって、送受波部１２１と一体的に形成されている。軸部１２２の内部には、振動子から電気信号を取り出して水中探知装置本体１３に出力するためのリード線が延びている。軸部１２２の外壁面には雄ネジ部が形成されており、この雄ネジ部はナット１７と螺合する。   Here, the transducer 12 fixed to the attachment member 4 will be briefly described. First, the transmitter / receiver 12 includes a transmission / reception unit 121 having a built-in vibrator, and a shaft portion 122 extending upward from the upper surface of the transmission / reception unit 121. The transmission / reception unit 121 is formed in a columnar shape, and the lower surface of the transmission / reception unit 121 is a transmission / reception surface 1211 for transmitting and receiving ultrasonic waves. The shaft portion 122 has a columnar shape having an outer diameter smaller than that of the wave transmitting / receiving unit 121 and is formed integrally with the wave transmitting / receiving unit 121. A lead wire for taking out an electrical signal from the vibrator and outputting it to the underwater detection device main body 13 extends inside the shaft portion 122. A male screw portion is formed on the outer wall surface of the shaft portion 122, and this male screw portion is screwed into the nut 17.

取付部材本体４１は、その内部に送受波器１２の送受波部１２１を収容するよう構成さえており、略円筒状の側壁部４１１と、側壁部４１１の上端部を封鎖する封鎖部４１２とを備えている。なお、側壁部４１１と封鎖部４１２とは一体的に形成されている。また、取付部材本体４１は、送受波部１２１を収容した状態において、送受信面１２１１を露出するように下面が開口している。   The mounting member main body 41 is configured to accommodate the wave transmitting / receiving part 121 of the wave transmitter / receiver 12 therein, and includes a substantially cylindrical side wall part 411 and a blocking part 412 for sealing the upper end part of the side wall part 411. I have. In addition, the side wall part 411 and the blocking part 412 are integrally formed. In addition, the attachment member main body 41 has a lower surface opened to expose the transmission / reception surface 1211 in a state where the wave transmitting / receiving unit 121 is accommodated.

側壁部４１１は、略円筒状に形成されており、側壁部４１１内に送受波器１２の送受波部１２１が嵌るように設計されている。すなわち、側壁部４１１の内径は、送受波部１２１の外径とほぼ合致するように設計されている。   The side wall part 411 is formed in a substantially cylindrical shape, and is designed so that the wave transmitting / receiving part 121 of the transducer 12 is fitted in the side wall part 411. That is, the inner diameter of the side wall part 411 is designed to substantially match the outer diameter of the wave transmitting / receiving part 121.

側壁部４１１は、その上部４１１１の外壁面に雄ネジ部が形成されている。この側壁部４１１に形成された雄ネジ部は、ガイド部材２におけるガイド部材本体２１の内壁面に形成された雌ネジ部と螺合する。この螺合によって、取付部材４は、ガイド部材２に取り付けられる。なお、この側壁部４１１の上部４１１１に形成された雄ネジ部が、本発明の取付機構に相当する。   The side wall portion 411 has a male screw portion on the outer wall surface of the upper portion 4111 thereof. The male screw portion formed on the side wall portion 411 is screwed with the female screw portion formed on the inner wall surface of the guide member main body 21 in the guide member 2. The attachment member 4 is attached to the guide member 2 by this screwing. In addition, the external thread part formed in the upper part 4111 of this side wall part 411 corresponds to the attachment mechanism of this invention.

側壁部４１１の下部４１１２は、上部４１１１よりも小さい外径に設計されている。このため、側壁部４１１の下部４１１２の外壁面と、ガイド部材２のガイド部材本体２１の内壁面との間に、隙間Ｇが形成されている。なお、下部４１１２の内径は、上部４１１１の内径と同じに設計されている。すなわち、下部４１１２の内壁面と上部４１１１の内壁面とは段差が形成されることなく連続的に形成されている。   The lower part 4112 of the side wall part 411 is designed to have a smaller outer diameter than the upper part 4111. For this reason, a gap G is formed between the outer wall surface of the lower portion 4112 of the side wall portion 411 and the inner wall surface of the guide member main body 21 of the guide member 2. The inner diameter of the lower portion 4112 is designed to be the same as the inner diameter of the upper portion 4111. That is, the inner wall surface of the lower part 4112 and the inner wall surface of the upper part 4111 are formed continuously without forming a step.

側壁部４１１の下端部には、肩部４１１３が形成されている。取付部材４をガイド部材２に取り付けるために、取付部材４とガイド部材２とを螺合させながら取付部材４をガイド部材２内に挿入した際、肩部４１１３がガイド部材２の突出部２３と当接する。この肩部４１１３と突出部２３とが当接することによって、取付部材４は、ガイド部材２への挿入方向（図３の下方向）において位置決めされる。このように肩部４１１３と突出部２３とが当接した状態において、送受波器１２の送受信面１２１１とガイド部材２の下端面とがほぼ合致する。また、取付部材４の下端面も送受信面１２１１とほぼ合致する。これにより、送受波器１２が取り付けられた箇所における船底では、ほとんど段差がない状態となっている。   A shoulder 4113 is formed at the lower end of the side wall 411. In order to attach the attachment member 4 to the guide member 2, when the attachment member 4 is inserted into the guide member 2 while screwing the attachment member 4 and the guide member 2, the shoulder portion 4113 and the protruding portion 23 of the guide member 2 Abut. When the shoulder 4113 and the protrusion 23 come into contact with each other, the attachment member 4 is positioned in the insertion direction into the guide member 2 (downward in FIG. 3). Thus, in the state where the shoulder portion 4113 and the protruding portion 23 are in contact with each other, the transmission / reception surface 1211 of the transducer 12 and the lower end surface of the guide member 2 substantially match. Further, the lower end surface of the attachment member 4 also substantially coincides with the transmission / reception surface 1211. Thereby, there is almost no level difference at the bottom of the ship where the transducer 12 is attached.

封鎖部４１２は、その中央部に、送受波器１２の軸部１２２を通すための貫通孔４１２１が形成されている。また、封鎖部４１２は、その上面の中央部に、スパナなどの工具と係合することができるような形状に形成された係合部４１２２を有している。詳細には、係合部４１２２は、その側壁面に、平坦に形成された面を一対有しており、この一対の面は平行となっている。この係合部４１２２にスパナを係合させて取付部材４を回転させることによって、取付部材４をガイド部材２に強固に螺合させることができる。なお、係合部４１２２の中央部に、上述した貫通孔４１２１が形成されている。   The sealing portion 412 has a through hole 4121 formed in the central portion thereof for passing the shaft portion 122 of the transducer 12. Moreover, the blocking part 412 has the engaging part 4122 formed in the shape which can be engaged with tools, such as a spanner, in the center part of the upper surface. Specifically, the engaging portion 4122 has a pair of flat surfaces formed on the side wall surface, and the pair of surfaces are parallel to each other. The attachment member 4 can be firmly screwed to the guide member 2 by engaging the spanner with the engaging portion 4122 and rotating the attachment member 4. Note that the above-described through hole 4121 is formed at the center of the engaging portion 4122.

係合部４１２２は中空に形成されており、係合部４１２２の下面には、送受波器１２の軸部１２２をガイドするよう、貫通孔４１２１の外周縁部から下方に延びるガイド筒４１２３が形成されている。このガイド筒４１２３の下端と、送受波器１２の送受波部１２１の上面とで、環状のパッキン１０１を押圧している。   The engaging portion 4122 is formed in a hollow shape, and a guide tube 4123 extending downward from the outer peripheral edge portion of the through hole 4121 is formed on the lower surface of the engaging portion 4122 so as to guide the shaft portion 122 of the transducer 12. Has been. The annular packing 101 is pressed by the lower end of the guide tube 4123 and the upper surface of the wave transmitting / receiving unit 121 of the wave transmitter / receiver 12.

フランジ部４２は、側壁部４１１の外壁面における上端部に形成されている。フランジ部４２は、側壁部４１１の外壁面から外方に向かって延びている。取付部材４をガイド部材２に取り付けた状態において、取付部材４のフランジ部４２は、ガイド部材２のガイド部材本体２１の上端部に形成された傾斜面との間で、Ｏリング１００を押圧する。   The flange portion 42 is formed at the upper end portion of the outer wall surface of the side wall portion 411. The flange portion 42 extends outward from the outer wall surface of the side wall portion 411. In a state where the attachment member 4 is attached to the guide member 2, the flange portion 42 of the attachment member 4 presses the O-ring 100 between the inclined surface formed on the upper end portion of the guide member main body 21 of the guide member 2. .

送受波器１２は、送受波部１２１を取付部材４内に収容され、軸部１２２と螺合するナット１７と協働して取付部材４の封鎖部４１２を挟み込むことによって、取付部材４に固定される。なお、ナット１７と封鎖部４１２とによって環状のパッキン１０２を押圧している。   The wave transmitter / receiver 12 has the wave transmitting / receiving portion 121 accommodated in the mounting member 4 and is fixed to the mounting member 4 by sandwiching the blocking portion 412 of the mounting member 4 in cooperation with the nut 17 screwed with the shaft portion 122. Is done. The annular packing 102 is pressed by the nut 17 and the blocking portion 412.

［取付方法］
次に、上述した取付構造１によって送受波器１２を船舶１０に取り付ける方法について図面を参照しつつ説明する。 [Mounting method]
Next, a method for attaching the transducer 12 to the ship 10 by the above-described attachment structure 1 will be described with reference to the drawings.

図２及び図３に示すように、まず、生け簀１４の底面を画定する船底板１５に貫通孔１６を形成する。そして、船底板１５の下側から、貫通孔１６に対してガイド部材２のガイド部材本体２１を挿入する。そして、貫通孔１６を介して船底板１５の上側に突出したガイド部材本体２１に対して、固定部材３を螺合させる。これにより、ガイド部材２のフランジ部２２と、固定部材３のフランジ部３２とが、船底板１５を挟み込むことになり、この結果、ガイド部材２が船底板１５に固定される。   As shown in FIGS. 2 and 3, first, the through hole 16 is formed in the ship bottom plate 15 that defines the bottom surface of the sacrifice 14. Then, the guide member main body 21 of the guide member 2 is inserted into the through hole 16 from the lower side of the ship bottom plate 15. Then, the fixing member 3 is screwed into the guide member main body 21 protruding above the ship bottom plate 15 through the through hole 16. As a result, the flange portion 22 of the guide member 2 and the flange portion 32 of the fixing member 3 sandwich the ship bottom plate 15, and as a result, the guide member 2 is fixed to the vessel bottom plate 15.

なお、上述したガイド部材２と固定部材３は、生け簀１４の船底板１５に予め取り付けられているスカッパーを構成する部品を流用してもよい。このようにスカッパーを構成する部品を流用する場合、船底板１５に貫通孔１６を形成する必要がなくなり、また、ガイド部材２及び固定部材３を船底板に取り付ける必要もなくなる。この結果、取付作業の作業時間及び手間を軽減することができる。   Note that the guide member 2 and the fixing member 3 described above may be diverted from components constituting a scapper that is attached in advance to the bottom plate 15 of the sacrifice 14. Thus, when diverting the components constituting the scapper, it is not necessary to form the through holes 16 in the ship bottom plate 15, and it is not necessary to attach the guide member 2 and the fixing member 3 to the ship bottom plate. As a result, it is possible to reduce the work time and labor of the attachment work.

続いて、取付部材４に対して送受波器１２を固定する。詳細には、まず、パッキン１０１を送受波器１２の送受波部１２１の上面に設置する。そして、取付部材４内に送受波器１２の送受波部１２１を収容する。このとき、送受波器１２の軸部１２２は、取付部材４の貫通孔４１２１から上側に突出した状態となっている。そして、軸部１２２にナット１７を螺合させることにより、ナット１７と送受波部１２１とで取付部材４の封鎖部４１２を挟み込み、この結果、送受波器１２を取付部材４に固定する。なお、ナット１７と取付部材４との間にはパッキン１０２が介在している。   Subsequently, the transducer 12 is fixed to the attachment member 4. Specifically, first, the packing 101 is installed on the upper surface of the wave transmitting / receiving unit 121 of the wave transmitter / receiver 12. Then, the transmission / reception unit 121 of the transducer 12 is accommodated in the attachment member 4. At this time, the shaft portion 122 of the transducer 12 is in a state of protruding upward from the through hole 4121 of the mounting member 4. Then, the nut 17 is screwed onto the shaft portion 122 to sandwich the blocking portion 412 of the mounting member 4 between the nut 17 and the wave transmitting / receiving unit 121, and as a result, the wave transmitting / receiving device 12 is fixed to the mounting member 4. A packing 102 is interposed between the nut 17 and the mounting member 4.

そして、送受波器１２が固定された取付部材４を、ガイド部材２に取り付ける。詳細には、取付部材４をガイド部材２に螺合させることで、取付部材４をガイド部材２内に挿入する。そして、取付部材４の下端部に形成された肩部４１１３がガイド部材２の突出部２３に当接するまで、取付部材４をガイド部材２内に挿入する。これにより、取付部材４がガイド部材２に取り付けられ、ひいては、送受波器１２がガイド部材２に取り付けられる。また、取付部材４の肩部４１１３がガイド部材２の突出部２３に当接したとき、送受波器１２の送受信面１２１１は、ガイド部材２内に位置している。詳細には、送受波器１２の送受信面１２１１は、ガイド部材２の下端面とほぼ面一の状態となっている。なお、送受波器１２の送受信面１２１１は、ガイド部材２の下端面よりも下方側、すなわち船底よりも外側に位置していてもよい。以上のようにして送受波器１２を船底板１５に取り付けた状態の図を図４及び図５に示す。なお、図４は送受波器１２を船底板１５に取り付けた状態を示す斜視図であり、図５は送受波器１２を船底板１５に取り付けた状態を示す側面図である。   Then, the attachment member 4 to which the transducer 12 is fixed is attached to the guide member 2. Specifically, the attachment member 4 is inserted into the guide member 2 by screwing the attachment member 4 to the guide member 2. Then, the attachment member 4 is inserted into the guide member 2 until the shoulder portion 4113 formed at the lower end portion of the attachment member 4 contacts the protruding portion 23 of the guide member 2. Thereby, the attachment member 4 is attached to the guide member 2, and consequently, the transducer 12 is attached to the guide member 2. Further, when the shoulder portion 4113 of the mounting member 4 comes into contact with the protruding portion 23 of the guide member 2, the transmission / reception surface 1211 of the transducer 12 is located in the guide member 2. Specifically, the transmission / reception surface 1211 of the transducer 12 is substantially flush with the lower end surface of the guide member 2. In addition, the transmission / reception surface 1211 of the transducer 12 may be located below the lower end surface of the guide member 2, that is, outside the ship bottom. FIGS. 4 and 5 show the state in which the transducer 12 is attached to the ship bottom plate 15 as described above. 4 is a perspective view showing a state in which the transducer 12 is attached to the ship bottom plate 15, and FIG. 5 is a side view showing a state in which the transducer 12 is attached to the ship bottom plate 15.

以上のようにしてガイド部材２に取り付けた送受波器１２を取り外して、ガイド部材２及び固定部材３をスカッパーとして利用することもできる。以下、ガイド部材２及び固定部材３を利用したスカッパーについて図面を参照しつつ説明する。図６はガイド部材２及び固定部材３を利用したスカッパーの側面断面図である。   As described above, the transducer 12 attached to the guide member 2 can be removed, and the guide member 2 and the fixing member 3 can be used as a scapper. Hereinafter, the scapper using the guide member 2 and the fixing member 3 will be described with reference to the drawings. FIG. 6 is a side sectional view of a scapper using the guide member 2 and the fixing member 3.

図６に示すように、まず、上述した取付構造１と同様に、ガイド部材２及び固定部材３が船底板１５に固定されている。そして、ガイド部材２の突出部２３の上面にメッシュ部材５が支持されている。メッシュ部材５は、生け簀１４内にゴミなどが浸入することを防ぐための部材であり、平面視が円形であって、格子状に形成されている。メッシュ部材５の外径は、ガイド部材２の内径とほぼ同じ又はそれよりも小さく、また、突出部２３上に載置できる程度の寸法に設計されている。   As shown in FIG. 6, first, similarly to the mounting structure 1 described above, the guide member 2 and the fixing member 3 are fixed to the ship bottom plate 15. The mesh member 5 is supported on the upper surface of the protruding portion 23 of the guide member 2. The mesh member 5 is a member for preventing dust and the like from entering the sacrificial cage 14, and is circular in plan view and formed in a lattice shape. The outer diameter of the mesh member 5 is approximately the same as or smaller than the inner diameter of the guide member 2, and is designed to have a size that can be placed on the protruding portion 23.

突出部２３上に載置されたメッシュ部材５は、押さえ部材６によって上から押さえつけられることにより、ガイド部材２に固定されている。この押さえ部材６は、平面視が環状に形成されており、その外径がガイド部材２のガイド部材本体２１の内径とほぼ合致する。また、押さえ部材６の外壁面には、雄ネジ部が形成されている。この押さえ部材６に形成された雄ネジ部は、ガイド部材２の雌ネジ部と螺合する。押さえ部材６は、ガイド部材２と螺合して下方へ進むことで、メッシュ部材５の外周縁部を突出部２３に対して押さえつける。これにより、メッシュ部材５は、突出部２３と押さえ部材６とによって挟み込まれて、ガイド部材２に固定される。   The mesh member 5 placed on the protrusion 23 is fixed to the guide member 2 by being pressed from above by the pressing member 6. The pressing member 6 is formed in an annular shape in plan view, and the outer diameter thereof substantially matches the inner diameter of the guide member main body 21 of the guide member 2. A male screw portion is formed on the outer wall surface of the pressing member 6. The male screw portion formed on the pressing member 6 is screwed with the female screw portion of the guide member 2. The pressing member 6 is screwed with the guide member 2 and proceeds downward to press the outer peripheral edge portion of the mesh member 5 against the protruding portion 23. Accordingly, the mesh member 5 is sandwiched between the protruding portion 23 and the pressing member 6 and is fixed to the guide member 2.

このように、ガイド部材２、固定部材３、メッシュ部材５、及び押さえ部材６によって、スカッパー２０を構成する。このスカッパー２０により、ゴミなどを除去した海水を生け簀１４内に取り入れることができる。   As described above, the guide member 2, the fixing member 3, the mesh member 5, and the pressing member 6 constitute the scapper 20. With this scapper 20, seawater from which dust and the like have been removed can be taken into the sacrifice 14.

また、生け簀１４内に海水を取り入れたくない場合、又は生け簀１４内の水を外部に排出したくない場合は、図７及び図８に示すように、蓋部材７を取り付けることによって、スカッパー２０を塞ぐことができる。図７は、蓋部材７が取り付けられたスカッパー２０を示す斜視図であり、図８は蓋部材７が取り付けられたスカッパー２０の側面断面図である。   Moreover, when it is not desired to take in seawater in the sacrificial cage 14 or when it is not desired to discharge the water in the sacrificial cage 14 to the outside, the cover member 7 is attached as shown in FIGS. Can be closed. FIG. 7 is a perspective view showing the scraper 20 to which the lid member 7 is attached, and FIG. 8 is a side sectional view of the scraper 20 to which the lid member 7 is attached.

蓋部材７は、円筒状の円筒部７１と、円筒部７１の上端を塞ぐ天板部７２とを備えている。なお、円筒部７１と天板部７２とは一体的に形成されている。円筒部７１は、その外径がガイド部材２の内径とほぼ同じとなっている。また、円筒部７１の外壁面には雄ネジ部が形成されており、この雄ネジ部は、ガイド部材２の雌ネジ部と螺合する。   The lid member 7 includes a cylindrical cylindrical portion 71 and a top plate portion 72 that closes the upper end of the cylindrical portion 71. The cylindrical portion 71 and the top plate portion 72 are integrally formed. The outer diameter of the cylindrical portion 71 is substantially the same as the inner diameter of the guide member 2. A male screw portion is formed on the outer wall surface of the cylindrical portion 71, and this male screw portion is screwed with the female screw portion of the guide member 2.

天板部７２は、平面視円形に形成されており、その外径は、円筒部７１の外径よりも大きく、ガイド部材２のガイド部材本体２１の外径とほぼ同じ寸法となっている。また、天板部７２は、その中央部には工具を差し込むための溝７２１が形成されている。この溝７２１に工具の先をはめ込み、工具を使用して蓋部材７を回転させることによって、蓋部材７の着脱を行うことができる。   The top plate portion 72 is formed in a circular shape in plan view, and the outer diameter thereof is larger than the outer diameter of the cylindrical portion 71 and has substantially the same dimension as the outer diameter of the guide member body 21 of the guide member 2. Further, the top plate portion 72 has a groove 721 for inserting a tool at the center thereof. The lid member 7 can be attached and detached by fitting the tip of the tool into the groove 721 and rotating the lid member 7 using the tool.

以上に説明した実施形態に係る取付構造１によれば、生け簀１４の底面を画定する船底板１５に形成した貫通孔１６を利用して送受波器１２を取り付けることができる。生け簀１４は、元々、水を取り入れることを前提とした構造となっているため、貫通孔１６を介して生け簀１４内に水が浸入してきても問題はない。このため、船体内への浸水を気にすることなく送受波器１２の取付作業を行うことができ、作業時間及び手間を軽減することができる。   According to the mounting structure 1 according to the embodiment described above, the transducer 12 can be mounted using the through holes 16 formed in the ship bottom plate 15 that defines the bottom surface of the sacrifice 14. Since the sacrificial cage 14 originally has a structure on the premise that water is taken in, there is no problem even if water enters the sacrificial cage 14 through the through hole 16. For this reason, the attachment work of the transducer 12 can be performed without worrying about the inundation into the ship's body, and the work time and labor can be reduced.

また、生け簀１４の船底を画定する船底板１５には、生け簀１４内に海水を取り入れたり、生け簀１４内の水を外部に排出するためのスカッパー２０が予め設置されている。このスカッパーは、その構成部品として、上述したガイド部材２を有している。このため、スカッパー２０の構成部品であるガイド部材２を流用し、取付部材４をガイド部材２に取り付けることができる。したがって、送受波器１２を取り付けるために船底板１５に貫通孔１６を新たに形成したり、ガイド部材２を取り付けたりする作業を省略することができ、この結果、作業時間及び手間をより軽減することができる。   Further, a shipper plate 15 that demarcates the bottom of the sacrificial cage 14 is preliminarily provided with a scapper 20 for taking seawater into the sacrificial cage 14 and discharging the water in the sacrificial cage 14 to the outside. This scapper has the above-described guide member 2 as its component. For this reason, the guide member 2 which is a component of the scraper 20 can be diverted and the attachment member 4 can be attached to the guide member 2. Therefore, the work of newly forming the through hole 16 in the ship bottom plate 15 or attaching the guide member 2 in order to attach the transducer 12 can be omitted. As a result, the work time and labor are further reduced. be able to.

また、取付部材４をガイド部材２に取り付けた状態において、送受波器１２の送受信面１２１１は、船底の外側に近いガイド部材２内に位置しているため、超音波の送受信感度を低下させることがない。   Moreover, in the state which attached the attachment member 4 to the guide member 2, since the transmission / reception surface 1211 of the transmitter / receiver 12 is located in the guide member 2 near the outer side of a ship bottom, it reduces the transmission / reception sensitivity of an ultrasonic wave. There is no.

また、上記実施形態に係る取付構造１において、ガイド部材２は、突出部２３を有しているため、取付部材４は、この突出部２３に当接することで、挿入方向において位置決めすることができる。この結果、送受波器１２の送受信面１２１１を適切な位置に設置することができる。   Further, in the mounting structure 1 according to the above-described embodiment, the guide member 2 has the protruding portion 23. Therefore, the mounting member 4 can be positioned in the insertion direction by contacting the protruding portion 23. . As a result, the transmission / reception surface 1211 of the transducer 12 can be installed at an appropriate position.

また、上記実施形態に係る取付構造１において、ガイド部材２が突出部２３を有しているため、この突出部２３を利用してメッシュ部材５を取り付けることができる。これにより、送受波器１２を使用しないときに、ガイド部材２及びメッシュ部材５によってスカッパー２０を構成することができる。   In addition, in the attachment structure 1 according to the above-described embodiment, the guide member 2 has the protruding portion 23, so that the mesh member 5 can be attached using the protruding portion 23. Thereby, when not using the transducer 12, the guide member 2 and the mesh member 5 can constitute the scraper 20.

また、上記実施形態に係る取付構造１において、取付部材４をガイド部材２に取り付けた状態において、送受波器１２の送受信面１２１１は、貫通孔１６から外部に対して露出している。すなわち、送受信面１２１１と外部との間に、メッシュ部材のような遮るものはない。このため、送受波器１２の送受信感度を低下させることがない。   In the mounting structure 1 according to the above embodiment, the transmission / reception surface 1211 of the transducer 12 is exposed from the through hole 16 to the outside in a state where the mounting member 4 is mounted on the guide member 2. That is, there is no obstruction like a mesh member between the transmission / reception surface 1211 and the outside. For this reason, the transmission / reception sensitivity of the transducer 12 is not reduced.

また、上記実施形態に係る取付構造１において、取付部材４は、ガイド部材２と螺合することによって、ガイド部材２に取り外し可能に取り付けられる。このため、必要時に送受波器１２を容易に取り付けることができるとともに、不要時には送受波器１２を容易に取り外すことができる。   In the attachment structure 1 according to the above embodiment, the attachment member 4 is detachably attached to the guide member 2 by screwing with the guide member 2. For this reason, the transducer 12 can be easily attached when necessary, and the transducer 12 can be easily detached when unnecessary.

また、上記実施形態に係る取付構造１において、取付部材４とガイド部材２とがＯリング１００を押圧している。この取付部材４とガイド部材２とでＯリング１００を押圧することによって生じるＯリング１００の反発力により、取付部材４がガイド部材２により強固に取り付けられる。   Further, in the mounting structure 1 according to the above embodiment, the mounting member 4 and the guide member 2 press the O-ring 100. The attachment member 4 is firmly attached to the guide member 2 by the repulsive force of the O-ring 100 generated by pressing the O-ring 100 between the attachment member 4 and the guide member 2.

また、上記実施形態に係る取付構造１において、取付部材４とガイド部材２との間にＯリング１００が介在しているため、取付部材４とガイド部材２との間から生け簀１４内に水が浸入することを防止することができる。これにより、例えば、生け簀１４を本来の用途とは異なる用途で利用している場合、例えば、生け簀１４を収納室などとして利用している場合にメリットがある。   In addition, in the mounting structure 1 according to the above-described embodiment, since the O-ring 100 is interposed between the mounting member 4 and the guide member 2, water enters the sacrifice 14 from between the mounting member 4 and the guide member 2. Intrusion can be prevented. Thereby, for example, there is a merit when the sacrifice 14 is used for an application different from the original use, for example, when the sacrifice 14 is used as a storage room or the like.
