Description

Installation structure and installation parts

technical field

The utility model relates to an installation structure and installation parts for installing a transceiver on a ship.

Background technique

For the purpose of detecting schools of fish in water, etc., underwater detecting devices such as fish detecting machines are widely used. This underwater detection device is installed on a ship or the like, and receives echoes reflected by objects such as schools of fish after a transceiver transmits an ultrasonic transmission beam into the water. In addition, the underwater detection device forms an image related to underwater information such as schools of fish by performing various processes on the received echo, and displays the image on the display device.

Transceivers are usually installed on the bottom of the ship. As the installation method of this transceiver, there are an installation method called an inner hull method and an installation method called a through hull method. First, an inner hull system will be described. In the inner hull system, for example, as shown in FIG. 2 of Patent Document 1, a tank is attached to the inner side of the bottom of a ship. Furthermore, the case is filled with liquid such as water, and the transceiver having the ultrasonic vibrator is held in the case. In such an inner shell system, the transceiver can be easily installed on the bottom of the ship, but on the other hand, since the transceiver transmits and receives ultrasonic waves through the bottom plate, there is a disadvantage that the sensitivity of ultrasonic transmission and reception is not good.

In contrast, in the through-hull system, a through-hole is formed in the bottom of the ship, and the transceiver is installed on the bottom of the ship so that the ultrasonic wave transmitting and receiving surface of the transceiver is exposed to the outside through the through-hole. Accordingly, the transceiver can directly transmit ultrasonic waves into the water without being separated from the bottom plate of the ship, and can directly receive the echoes. Therefore, the through-hull system has an advantage in that the transmission and reception sensitivity of ultrasonic waves of the transceiver is better than that of the inner hull system.

Patent Document 1: Japanese Patent Laid-Open No. 2007-285730

However, when the transceiver is attached to the bottom of the ship by penetrating the hull, it is necessary to form a through hole in the bottom of the ship. Therefore, if the mounting operation of the transceiver is improper, there is a risk of water intruding into the hull through the through hole. Therefore, in the conventional through-hull system, in order to prevent water immersion into the hull, it is necessary to carefully perform the installation work of the transceiver, and there is a problem that time and labor are required for the installation operation of the transceiver.

The transceiver 12 is installed in a temporary storage box 14, which is installed near the center of the ship 10, and the underwater detection device main body 13 is installed near the operator's seat.

Next, an attachment structure for attaching the transceiver 12 to the holding tank 14 included in the ship 10 will be described with reference to the drawings. FIG. 2 is an exploded perspective view of the mounting structure according to the embodiment of the present invention, and FIG. 3 is a side sectional view of the mounting structure according to the embodiment of the present invention. In addition, "up" and "down" in the following description refer to the up and down directions in FIG. 3 .

As shown in FIGS. 2 and 3 , the installation structure 1 according to this embodiment is an installation structure for installing the transceiver 12 on the holding tank 14 , and includes a guide member 2 , a fixing member 3 and an installation member 4 . Next, details of each component will be described.

[boot parts]

The guide member 2 is fixed to the ship bottom plate 15 by pinching the ship 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 is integrally formed with the flange portion 22 and the protruding portion 23 .

The guide member main body 21 is a cylindrical part formed so as to extend along the inner wall surface of the through-hole 16 formed in the ship bottom plate 15 defining the bottom surface of the holding tank 14 . That is, the guide member main body 21 has a cylindrical shape fitted into the through-hole 16 of the ship bottom plate 15 , and is designed such that its outer diameter substantially coincides with the inner diameter of the through-hole 16 . In the guide member main body 21 , a male screw portion is formed on an outer wall surface, and a female screw portion is formed on an inner wall surface. In addition, an inclined surface inclined inwardly is formed on the upper end portion of the guide member main body 21 , and an O-ring 100 as an elastic member is pressed between the inclined surface and the mounting member 4 . In addition, 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 .

The flange part 22 is formed at the lower end part 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 . Moreover, in the state which fixed the guide member 2 to the ship bottom plate 15, the upper surface of the flange part 22 abuts on the ship bottom which is the lower surface of the ship bottom plate 15. As shown in FIG. In addition, the lower surface of the flange part 22 is inclined so that the thickness of the flange part 22 becomes thinner as it goes outward. Thus, by inclining the lower surface of the flange part 22, the level|step difference of the boundary part of the flange part 22 and the bottom plate 15 becomes small.

The protruding portion 23 is formed at the lower end portion 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 . In addition, the protruding portion 23 is formed in a ring shape. That is, the protruding portion 23 is formed along the circumferential direction of the inner wall surface of the guide member main body 21 .

[fixed parts]

The fixing member 3 is a member for fixing the above-mentioned guide member 2 to the bottom plate 15 of the ship, and includes a cylindrical portion 31 and a flange portion 32 . In addition, the cylindrical portion 31 is integrally formed with the flange portion 32 .

The cylindrical portion 31 has a cylindrical shape, and is designed such that its inner diameter substantially coincides with the outer diameter of the guide member main body 21 of the guide member 2 . In addition, a female screw portion is formed on the inner wall surface of the cylindrical portion 31 . The female thread portion formed on the inner wall surface of the cylindrical portion 31 is screwed to the male thread portion formed on the outer wall surface of the guide member main body 21 .

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 bottom plate 15 by the fixing member 3 , the lower surface of the flange portion 32 abuts on the upper surface of the bottom plate 15 , that is, the surface of the bottom plate 15 on the side of the holding tank 14 . The guide member 2 is fixed to the ship bottom plate 15 by sandwiching the ship bottom plate 15 between the flange portion 32 of the fixing member 3 and the flange portion 22 of the guide member 2 .

[mounting parts]

The mounting member 4 is a member for mounting the transceiver 12 to the guide member 2 . The mounting member 4 includes a mounting member main body 41 and a flange portion 42 . In addition, the mounting member main body 41 is integrally formed with the flange portion 42 .

Here, the transceiver 12 fixed to the mounting member 4 will be briefly described. First, the transceiver 12 includes a transceiver section 121 incorporating a vibrator, and a shaft section 122 extending upward from the upper surface of the transceiver section 121 . The transmitting and receiving unit 121 is formed in a cylindrical shape, and the lower surface of the transmitting and receiving unit 121 constitutes a transmitting and receiving surface 1211 for transmitting and receiving ultrasonic waves. The shaft portion 122 has a cylindrical shape having an outer diameter smaller than that of the transceiver portion 121 and is integrally formed with the transceiver portion 121 . Lead wires are extended inside the shaft portion 122 , and the lead wires are used to take out electrical signals from the vibrator and output them to the main body 13 of the underwater detection device. A male screw portion is formed on the outer wall surface of the shaft portion 122 , and the male screw portion is screwed into the nut 17 .

The mounting member main body 41 is configured to accommodate the transceiver unit 121 of the transceiver 12 therein, and includes a substantially cylindrical side wall portion 411 and a blocking portion 412 blocking the upper end of the side wall portion 411 . In addition, the side wall portion 411 is integrally formed with the blocking portion 412 . In addition, an opening is formed in the attaching member main body 41 so that the lower surface exposes the transmitting and receiving surface 1211 in a state where the transmitting and receiving unit 121 is accommodated.

The side wall portion 411 is formed in a substantially cylindrical shape, and is designed such that the transceiver portion 121 of the transceiver 12 is inserted into the side wall portion 411 . That is to say, the inner diameter of the side wall portion 411 is designed to be approximately the same as the outer diameter of the transceiver portion 121 .

A male screw portion is formed on the outer wall surface of the upper portion 4111 of the side wall portion 411 . The male screw portion formed on the side wall portion 411 is screwed to the female screw portion formed on the inner wall surface of the guide member main body 21 of the guide member 2 . By this screwing, the attachment member 4 is attached to the guide member 2 . 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.

The lower portion 4112 of the side wall portion 411 is designed to be smaller than the outer diameter of the upper portion 4111 . Therefore, 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 . In addition, the inner diameter of the lower part 4112 is designed to be the same as that of the upper part 4111 . That is, the inner wall surface of the lower part 4112 and the inner wall surface of the upper part 4111 do not form a step, but are formed continuously.

On the lower end portion of the side wall portion 411, a shoulder portion 4113 is formed. 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 4113 comes into contact with the protruding portion 23 of the guide member 2 . When the shoulder portion 4113 comes into contact with the protruding portion 23 , the attachment member 4 is positioned in the direction of insertion into the guide member 2 (downward direction in FIG. 3 ). In this way, the transmitting and receiving surface 1211 of the transceiver 12 substantially coincides with the lower end surface of the guide member 2 in a state where the shoulder portion 4113 is in contact with the protruding portion 23 . In addition, the lower end surface of the mounting member 4 also substantially coincides with the transmitting and receiving surface 1211 . Accordingly, there is almost no step on the bottom of the ship where the transceiver 12 is installed.

A through hole 4121 through which the shaft portion 122 of the transceiver 12 passes is formed in the central portion of the blocking portion 412 . In addition, an engaging portion 4122 is provided at the central portion of the upper surface of the blocking portion 412, and the engaging portion 4122 is formed in a shape capable of engaging with a tool such as a wrench. Specifically, the side wall surface of the engaging portion 4122 has a pair of flatly formed surfaces, and the pair of surfaces are parallel. By engaging the wrench with this engaging portion 4122 and rotating the mounting member 4 , the mounting member 4 can be firmly screwed to the guide member 2 . In addition, the above-mentioned through hole 4121 is formed in the central portion of the engaging portion 4122 .

The engaging portion 4122 is hollow, and a guide cylinder 4123 extending downward from the outer peripheral 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 transceiver 12 . The ring-shaped packing 101 is pressed by the lower end of the guide cylinder 4123 and the upper surface of the transmitting and receiving portion 121 of the transceiver 12 .

The flange portion 42 is formed on 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 . When the mounting member 4 is attached to the guide member 2 , the flange portion 42 of the mounting 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 .

By accommodating the transceiver part 121 in the mounting member 4 , the transceiver part 121 cooperates with the nut 17 screwed to the shaft part 122 to sandwich the blocking part 412 of the mounting part 4 , whereby the transceiver 12 is fixed to the mounting part 4 . In addition, the annular packing 102 is pressed by the nut 17 and the blocking portion 412 .

[installation method]

Next, a method of attaching the transceiver 12 to the ship 10 using the above-mentioned attaching structure 1 will be described with reference to the drawings.

As shown in FIGS. 2 and 3 , first, the through-hole 16 is formed in the bottom plate 15 defining the bottom surface of the holding tank 14 . And, the guide member main body 21 of the guide member 2 is inserted into the through hole 16 from the lower side of the bottom plate 15 . And the fixing member 3 is screwed to the guide member main body 21 protruding to the upper side of the ship bottom plate 15 through the through-hole 16. As shown in FIG. Accordingly, the flange portion 22 of the guide member 2 and the flange portion 32 of the fixing member 3 sandwich the bottom plate 15 , and as a result, the guide member 2 is fixed to the bottom plate 15 .

In addition, the above-mentioned guide member 2 and fixing member 3 may be converted to members constituting drainage holes attached to the bottom plate 15 defining the bottom surface of the holding tank 14 in advance. When the members constituting the drainage holes are used in this way, it is not necessary to form the through-hole 16 in the bottom plate 15, and it is also unnecessary to attach the guide member 2 and the fixing member 3 to the bottom plate. As a result, it is possible to reduce the work time and labor required for the installation work.

Next, the transceiver 12 is fixed to the mounting part 4 . In detail, first, the filler 101 is provided on the upper surface of the transceiver portion 121 of the transceiver 12 . Furthermore, the transceiver unit 121 of the transceiver 12 is accommodated in the mounting member 4 . At this time, the shaft portion 122 of the transceiver 12 protrudes upward from the through hole 4121 of the mounting member 4 . Then, by screwing the nut 17 to the shaft portion 122 , the blocking portion 412 of the attachment member 4 is sandwiched between the nut 17 and the transceiver portion 121 , and as a result, the transceiver 12 is fixed to the attachment member 4 . In addition, a packing 102 is interposed between the nut 17 and the blocking portion 4 .

And, the mounting member 4 to which the transceiver 12 is fixed is mounted to the guide member 2 . Specifically, the mounting member 4 is inserted into the guide member 2 by screwing the mounting member 4 to the guide member 2 . Then, the mounting member 4 is inserted into the guide member 2 until the shoulder 4113 formed on the lower end portion of the mounting member 4 abuts against the protruding portion 23 of the guide member 2 . Accordingly, the attachment member 4 is attached to the guide member 2 , and furthermore, the transceiver 12 is attached to the guide member 2 . In addition, when the shoulder 4113 of the installation component 4 abuts against the protruding portion 23 of the guide component 2 , the transceiving surface 1211 of the transceiver 12 is located inside the guide component 2 . More specifically, the transmission and reception surface 1211 of the transceiver 12 is substantially flush with the lower end surface of the guide member 2 . In addition, the transmission and reception surface 1211 of the transceiver 12 may be located on the lower side than the lower end surface of the guide member 2, that is, it may be located on the outer side than the bottom of the ship. As mentioned above, the figure which shows the state which attached the transceiver 12 to the bottom plate 15 is shown in FIG.4 and FIG.5. In addition, FIG. 4 is a perspective view showing a state in which the transceiver 12 is attached to the bottom plate 15 of the ship, and FIG. 5 is a side view showing a state in which the transceiver 12 is attached to the bottom plate 15 of the ship.

As described above, the transceiver 12 attached to the guide member 2 can also be detached, and the guide member 2 and the fixing member 3 can be used as drainage holes. Next, the drainage hole obtained by 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 the drainage hole obtained by using the guide member 2 and the fixing member 3 .

As shown in FIG. 6 , first, the guide member 2 and the fixing member 3 are fixed to the bottom plate 15 in the same manner as the above-mentioned attachment structure 1 . Furthermore, 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 garbage and the like from infiltrating into the holding tank 14 , and is circular in plan view (planar view) and formed in a grid shape. The outer diameter of the mesh member 5 is substantially the same as or smaller than the inner diameter of the guide member 2 , and is designed to be a size that can be placed on the protruding portion 23 .

The mesh member 5 placed on the protruding portion 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 a ring shape in plan view, and its outer diameter substantially coincides with the inner diameter of the guide member main body 21 of the guide member 2 . In addition, 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 to the female screw portion of the guide member 2 . The pressing member 6 is screwed with the guide member 2 and travels downward to press the outer peripheral portion of the mesh member 5 against the protruding portion 23 . Accordingly, the mesh member 6 is fixed to the guide member 2 by sandwiching between the protruding portion 23 and the pressing member 6 .

In this way, the drain hole 20 is constituted by the guide member 2 , the fixing member 3 , the mesh member 5 , and the pressing member 6 . Seawater from which garbage and the like have been removed can be introduced into the holding tank 14 through the drainage hole 20 .

In addition, when it is not desired to introduce seawater into the holding tank 14, or to discharge the water in the holding tank 14 to the outside, as shown in FIGS. 7 and 8, the drain hole can be blocked by installing the cover member 7. 20. 7 is a perspective view showing the drain hole 20 with the cover member 7 attached, and FIG. 8 is a side sectional view of the drain hole 20 with the cover member 7 attached.

The cover member 7 includes a cylindrical cylindrical portion 71 and a top plate portion 72 that closes the upper end of the cylindrical portion 71 . In addition, the cylindrical portion 71 is integrally formed with the top plate portion 72 . The outer diameter of the cylindrical portion 71 is substantially the same as the inner diameter of the guide member 2 . In addition, a male screw portion is formed on the outer wall surface of the cylindrical portion 71 , and the male screw portion is screwed to the female screw portion of the guide member 2 .

The top plate portion 72 is formed in a circular shape in plan view, and has an outer diameter larger than that of the cylindrical portion 71 and substantially the same size as the outer diameter of the guide member main body 21 of the guide member 2 . In addition, a groove 721 for inserting a tool is formed in the center portion of the top plate portion 72 . By fitting the head of a tool into the groove 721 and rotating the cover member 7 using the tool, the cover member 7 can be attached and detached.

According to the mounting structure 1 according to the embodiment described above, the transceiver 12 can be mounted using the through hole 16 formed in the ship bottom plate 15 defining the bottom surface of the holding tank 14 . The holding tank 14 is originally constructed on the premise of introducing water, so there is no problem even if water infiltrates into the holding tank 14 through the through-hole 16 . Therefore, the installation operation of the transceiver 12 can be performed without worrying about the water immersion in the ship, and the operation time and manpower can be reduced.

In addition, on the bottom plate 15 of the bottom of the tank 14 demarcated, a drain hole 20 is provided in advance, and the drain hole 20 is used to introduce seawater into the tank 14 or discharge the water in the tank 14 temporarily. to the outside. This drainage hole has the above-mentioned guide member 2 as its constituent member. Therefore, the guide member 2 that is a constituent member of the drain hole 20 can be repurposed, and the attachment member 4 can be attached to the guide member 2 . Therefore, it is possible to omit the operation of newly forming the through-hole 16 in the bottom plate 15 or attaching the guide member 2 in order to attach the transceiver 12, and as a result, it is possible to further reduce operation time and labor.

In addition, since the transceiving surface 1211 of the transceiver 12 is located in the outer guide member 2 close to the bottom of the ship when the mounting member 4 is attached to the guide member 2, the ultrasonic transceiving sensitivity is not lowered.

In addition, in the mounting structure 1 according to the above-described embodiment, since the guide member 2 has the protruding portion 23 , the mounting member 4 can be positioned in the insertion direction by abutting against the protruding portion 23 . As a result, the transmission and reception surface 1211 of the transceiver 12 can be installed at an appropriate position.

In addition, in the mounting structure 1 according to the above-described embodiment, the guide member 2 has the protruding portion 23 , and therefore the mesh member 5 can be mounted using the protruding portion 23 . Accordingly, when the transceiver 12 is not used, the drain hole 20 can be constituted by the guide member 2 and the mesh member 5 .

In addition, in the mounting structure 1 according to the above-described embodiment, the transmitting and receiving surface 1211 of the transceiver 12 is exposed to the outside through the through hole 16 in a state where the mounting member 4 is mounted on the guide member 2 . That is, there is no blocking member such as a mesh member between the transmitting and receiving surface 1211 and the outside. Therefore, the transmission/reception sensitivity of the transceiver 12 is not lowered.

In addition, in the mounting structure 1 according to the above-described embodiment, the mounting member 4 is detachably attached to the guide member 2 by being screwed to the guide member 2 .
