Inundation into the ship can be prevented.

  Next, the mounting structure 50 for the outboard equipment 51 will be described with reference to FIGS. 1 to 3. The mounting structure 50 for the outboard equipment 51 is a structure in which the outboard equipment 51 can be detachably attached to the waterproof connector 11 that is watertightly attached to the outboard bottom plate 5. As the outboard equipment 51, an underwater camera, an underwater light, various sensors, and the like can be applied. In the following description, a case where the underwater camera 51 is applied as the outboard equipment 51 will be described.

  The mounting structure 50 for the outboard equipment 51 includes the waterproof connector 11, an extension cable 52 having one end connected to the waterproof connector 11, and an underwater camera 51 connected to the other end of the extension cable 52. As described above, the waterproof connector 11 has the female terminal portion 15 disposed at the bottom of the immersion hole 25. The extension cable 52 has a male terminal portion 55 at one end and a female terminal portion 56 at the other end. The underwater camera 51 includes an imaging unit 60 that has a lens and the like and photographs underwater, and a male-side terminal unit 61 that is connected to the imaging unit 60.

  Accordingly, the male terminal portion 55 of the extension cable 52 is connected to the female terminal portion 15 of the waterproof connector 11, and the male terminal portion 61 of the underwater camera 51 is connected to the female side terminal portion 56 of the extension cable 52. Is done. At this time, since the male terminal portion 55 of the extension cable 52 connected to the waterproof connector 11 is accommodated in the immersion hole 25, the male terminal portion 55 does not protrude from the ship bottom outer plate 5. As a result, the male terminal portion 55 of the extension cable 52 is less likely to be subjected to a load such as a water flow, so that the extension cable 52 is less likely to be detached from the waterproof connector 11. The installation direction from the waterproof connector 11 to the underwater camera 51 via the extension cable 52 is the same as the ship width direction.

  In addition, the mounting structure 50 for the outboard equipment 51 includes an installation plate 70 for installing the underwater camera 51, an installation jig 71 for installing the extension cable 52, and a fixing plate 72 for fixing the underwater camera 51. And a protective cover 73 that covers the underwater camera 51.

  The installation plate 70 is formed in a rectangular plate shape, and is disposed in the vicinity of the waterproof connector 11 so that the longitudinal direction thereof is the same as the ship width direction. The installation plate 70 is joined to the ship bottom outer plate 5 by welding or the like. The installation plate 70 is threaded with a plurality of female screws for fixing a fixing plate 72 described later.

  The fixing plate 72 is integrally formed by a covering portion 77 that covers the underwater camera 51 installed on the installation plate 70 and a pair of fixing portions 78 and 78 that are bolted to the installation plate 70. Specifically, as shown in FIG. 2, the covering portion 77 is formed in an inverted U shape when viewed from the front, and the pair of fixing portions 78, 78 extends from both ends of the covering portion 77 along the installation plate 70. It is formed to extend outward in the ship length direction.

  Thus, the underwater camera 51 installed on the installation plate 70 is covered with the covering portion 77 of the fixing plate 72, and in this state, the pair of fixing portions 78 and 78 of the fixing plate 72 and the installation plate 70 are fastened with bolts. Thus, the underwater camera 51 is fixed to the installation plate 70. In addition, since the installation plate 70 and the fixed plate 72 are fastened with a double nut, it is difficult to loosen.

  The installation jig 71 is formed in a concave handle shape, and is disposed on the installation plate 70, and is interposed between the extension cable 52 and the installation plate 70. Specifically, the installation jig 71 includes a pair of column portions 80 erected on the installation plate 70 and a cable installation table 81 spanned between the pair of column portions 80. The extension cable 52 installed on the cable installation table 81 is fixed together with the cable installation table 81 by a binding band 82.

  The protective cover 73 is formed in a gable shape. Specifically, the protective cover 73 is formed by bending a rectangular iron plate from its center. The protective cover 73 is disposed so as to be convex with respect to the bottom shell outer plate 5, and the bent portion is the topmost portion 85, and the extending direction of the topmost portion 85 is the same as the width direction of the boat. It arrange | positions so that it may become. At this time, the extension cable 52 and the underwater camera 51 are disposed immediately below the extending top portion 85. That is, the extending direction of the topmost part 85 coincides with the installation direction of the extension cable 52 and the underwater camera 51. A pair of contact portions 86, 86 of the protective cover 73 and the ship bottom outer plate 5 are joined by welding or the like with the topmost portion 85 interposed therebetween.

  Accordingly, when the ship navigates, the flow direction (water flow direction) of the water flowing along the ship bottom outer plate 5 becomes the ship length direction, so that the water flow direction is orthogonal to the extending direction of the topmost portion 85 of the protective cover 73. That is, when the water flow that flows along the ship bottom outer plate 5 faces the protective cover 73, the water flow flows from one contact portion 86 toward the topmost portion 85, and after passing through the topmost portion 85, the other contact portion 86. It flows toward. At this time, the protective cover 73 formed in the gable shape can suitably guide the water flow, so that the disturbance of the water flow that has passed through the protective cover 73 can be suppressed.

  According to the above configuration, the waterproof connector 11 can be watertightly attached to the ship bottom outer plate 5, and the outboard equipment 51 such as an underwater camera can be connected to the waterproof connector 11. Even if a load is applied to or removed from the underwater camera 51 connected to the waterproof connector 11, the underwater camera 51 is disconnected at the connection portion between the waterproof connector 11 and the extension cable 52 or the connection portion between the extension cable 52 and the underwater camera 51. Therefore, water does not enter the inside of the ship and water can be prevented from entering the ship.

  Further, since the female terminal portion 15 of the waterproof connector 11 is disposed at the bottom of the immersion hole 25, the connection portion between the waterproof connector 11 and the extension cable 52 is accommodated inside the immersion hole 25. Thereby, since the load added to the connection part of the waterproof connector 11 and the extension cable 52 can be reduced, the extension cable 52 can make it difficult to remove | deviate with respect to the waterproof connector 11. FIG.

  Furthermore, by providing the protective cover 73 that covers the underwater camera 51 and the extension cable 52, it is possible to prevent the collision of the collision object that comes toward the underwater camera 51 and the extension cable 52. In addition, since the protective cover 73 is formed in a gable shape, the disturbance of the water flow that has passed through the protective cover 73 can be suppressed.

  Next, with reference to FIG. 4 thru | or FIG. 6, the attachment structure 100 of the outboard equipment 51 which concerns on Example 2 is demonstrated. Only different parts will be described in order to avoid duplicate descriptions. FIG. 4 is a side cross-sectional view schematically illustrating the waterproof connector and the outboard equipment mounting structure according to the second embodiment. FIG. 5 is a schematic view of the outboard equipment mounting structure according to the second embodiment. FIG. FIG. 6 is a plan view schematically showing the periphery of the waterproof connector and outboard equipment mounting structure according to the second embodiment. In the mounting structure 100 for the outboard equipment 51 of the second embodiment, the protective cover 110 is formed in a semi-cylindrical shape, and accordingly, the installation area of the installation plate 105 is larger than that of the first embodiment. .

  Specifically, the installation plate 105 is formed in a rectangular plate shape, and is disposed so as to cover the connector base 12 so that the longitudinal direction thereof is the same as the ship length direction. The installation plate 105 is formed with a notch 107 in which a portion covering the connector pedestal 12 is formed in a circular shape, and the installation plate 105 is joined to the ship bottom outer plate 5 by welding or the like. The installation plate 100 is threaded with a female screw for fixing the fixing plate 72 and a female screw for fixing the protective cover 110.

  The protective cover 110 is configured to fix the cover main body 113 formed in a semi-cylindrical shape, an end surface cover 114 that closes an opening in one end surface of the cover main body 113, and the cover main body 113 and the end surface cover 114 to the installation plate 105. The cover fixing plate 115 is integrally formed.

  One end of the cover main body 113 formed in a semi-cylindrical shape is cut out at an acute angle from the outer peripheral surface of the cover main body 113 toward the axis on the one end side. And the end surface cover 114 is arrange | positioned by obstruct | occluding the opening part of one edge part notched. Thereby, the end surface cover 114 is disposed at an acute angle with respect to the ship bottom outer plate 5. The cover fixing plate 115 is disposed around the cover main body 113 excluding the other end side, and is formed in a concave shape in plan view along the installation plate 105.

  The protective cover 110 configured in this manner is disposed so that the main body cover thereof is convex with respect to the ship bottom skin 5, and the axial direction of the cover main body 113 is disposed in the same direction as the ship length direction. The Furthermore, the protective cover 110 is disposed such that the end surface cover 114 is on the bow side in the ship length direction. An extension cable 52 and an underwater camera 51 are disposed inside the cover main body 113. That is, the axial center of the cover main body 113 coincides with the installation direction of the extension cable 52 and the underwater camera 51. The protective cover 110 disposed on the installation plate 105 is fixed to the installation plate 105 by fastening the cover fixing plate 115 and the installation plate 105 with bolts. Also in this case, since the installation plate 70 and the protective cover 110 are fastened with a double nut, it is difficult to loosen.

  Therefore, when the ship navigates, the flow direction (water flow direction) of the water flowing along the ship bottom outer plate 5 is the ship length direction, so the water flow direction is the same as the axial direction of the cover main body 113 of the protective cover 110. That is, when the water flow flowing along the ship bottom outer plate 5 faces the protective cover 110, the water flow passes through the end surface cover 114 and then passes through the cover main body 113. At this time, since the end surface cover 114 is disposed at an acute angle, the water flow can be suitably guided, and the disturbance of the water flow that has passed through the protective cover 110 can be suppressed.

  According to the above configuration, the installation direction of the protective cover 110 (the axial direction of the cover main body 113) can be the ship length direction, so that the installation direction of the underwater camera 51 and the extension cable 52 can be the ship length direction. Further, since the end surface cover 114 can be disposed at an acute angle with respect to the ship bottom outer plate 5, the disturbance of the water flow that has passed through the protective cover 110 can be suppressed.

  In the first and second embodiments, the waterproof connector 11 is disposed at the bottom of the immersion hole 25, but the female terminal portion 15 of the waterproof connector 11 protrudes from the ship bottom outer plate 5 without forming the immersion hole 25. It may be arranged.

  As described above, the waterproof connector mounting structure and the outboard equipment mounting structure according to the present invention are useful when the outboard equipment is attached to the outer plate of the ship, and in particular, when water intrusion into the ship is prevented.
