Mode for Carrying Out the Invention

[0009] <First Embodiment> (Ship) Hereinafter, the ship 1 according to the first embodiment of the present disclosure will be described with reference to FIGS. 1 to 7. The ship 1 shown in FIG. 1 is a ship 1 capable of continuously dropping the running body F. The running body F is, for example, an unmanned underwater vehicle (UUV). The running body F is used, for example, as a survey machine for collecting information on the seabed. The running body F is a precision airframe that is easily damaged by impact. The running body F is formed in a cylindrical shape, for example. The ship 1 includes a hull 2, a rail 3, a support base 4, a fixing part 5, a cable body 6, and a winch 7.

[0010] Hereinafter, the traveling direction D1 of the ship 1 may be simply referred to as the "traveling direction D1", and the ship width direction D2 of the ship 1 may be simply referred to as the "ship width direction D2". The traveling direction D1 and the ship width direction D2 are orthogonal.

[0011] (Hull) The hull 2 is formed in an elongated shape in the traveling direction D1. Hereinafter, the front side of the hull 2 in the traveling direction D1 may be referred to as the bow, and the rear side of the hull 2 in the traveling direction D1 may be referred to as the stern 2b. As shown in FIGS. 1 to 3, the hull 2 has a deck 20, an outer surface 21, and a bottom 22.

[0012] (Deck) The deck 20 extends in the horizontal direction. An upper structure (not shown) such as a bridge is installed on the deck 20.

[0013] (Outer surface) The outer surface 21 is connected to the edge of the deck 20. The outer surface 21 extends downward from the outside of the deck 20. The outer surface 21 has a side hull 23 and a stern slope 24.

[0014] (Side hull) A pair of side hulls 23 are provided facing each other in the ship width direction D2.

[0015] (Stern slope) The stern slope 24 is provided across the ends on the stern 2b side of the pair of side hulls 23. The stern slope 24 extends in the vertical direction. The upper end of the stern slope 24 is connected to the end on the stern 2b side of the deck 20. The stern slope 24 is formed in a slope shape so as to gradually linearly separate from the deck 20 in the rear side of the traveling direction D1 among the horizontal directions from the upper end toward the waterline WL.

[0016] (Bottom hull) The bottom hull 22 connects the lower parts of the pair of side hulls 23 and the lower part of the stern slope 24.

[0017] (Rail) The rail 3 is provided at the stern 2b of the hull 2. The rail 3 extends from the stern 2b to the rear side of the traveling direction D1 of the hull 2. The rail 3 extends linearly in the traveling direction D1 when viewed from the vertical direction. A pair of rails 3 are provided spaced apart in the ship width direction D2. The rail 3 has a deck rail part 30, an outer surface rail part 31, and a rail groove 32.

[0018] (Deck rail part) The deck rail part 30 is provided on the deck 20. The deck rail part 30 extends onto the deck 20 from the upper end of the stern slope 24. More specifically, the deck rail part 30 extends linearly in the rear side of the traveling direction D1 from the upper end of the stern slope 24 to the deck 20.

[0019] (Outer surface rail part) The outer rail section 31 is provided on the outer surface 21. The outer rail section 31 is provided on the stern slope 24 of the outer surface 21. The outer rail section 31 extends vertically along the stern slope 24, and its lower end reaches the waterline WL. The outer rail section 31 extends linearly along the stern slope 24, from the stern 2b end of the deck rail section 30 to the lower end of the stern slope 24, towards the rear in the direction of travel D1.

[0020] (Rail groove) The rail groove 32 is provided on the upper surface of the rail 3. The rail groove 32 opens in the vertical direction. Furthermore, the rail groove 32 extends along the entire length of the rail 3 in the direction of travel D1, from the front end to the rear end. In other words, the rail groove 32 also opens on both sides in the direction of travel D1. The cross-sectional shape of the rail 3, as viewed from the direction of its extension, is a U-shape that opens upward due to the rail groove 32.

[0021] (Support stand) The support base 4 is installed on the rail 3. The support base 4 is slidable along the rail 3. Multiple support bases 4 are provided along the direction of extension of the rail 3. The support base 4 is capable of supporting the vehicle F. The support base 4 comprises a support base body 40 and an insertion portion 41.

[0022] (Support body) As shown in Figure 4, the support base body 40 is provided in the shape of a rectangular prism with a rectangular cross-section extending in the ship width direction D2. An arrangement groove 42 is formed on the side of the support base body 40 opposite to the rail 3. The arrangement groove 42 opens on the side opposite to the rail 3 and is formed in a U-shape when viewed from the ship width direction D2. The cruising body F (see Figure 1) is positioned in the arrangement groove 42 along the ship width direction D2.

[0023] (Insertion section) The insertion portion 41 is provided on the side of the support base body 40 opposite to the arrangement groove 42. One pair of insertion portions 41 are provided at each end of the support base body 40 in the extending direction. The insertion portions 41 are provided so as to protrude from the support base body 40. Each insertion portion 41 extends perpendicular to the extending direction of the support base body 40. The insertion portions 41 are inserted into the rail groove 32. The insertion portions 41 are arranged along the rail groove 32. The insertion portion 41 is provided with a mounting hole 43. The mounting hole 43 penetrates the insertion portion 41 in the direction of its extension.

[0024] (fixed part) As shown in Figure 5, the fixing parts 5 are provided on the support base 4. The fixing parts 5 are provided to fix the vessel F to the support base 4 and to allow it to be released near the waterline WL. Three fixing parts 5 are provided between the pair of insertion parts 41. The three fixing parts 5 are arranged in the direction of extension of the support base 4. The fixed part 5 includes a switching mechanism 50, a fixing band 51, and a sensor 52.

[0025] (Switching mechanism) The switching mechanism 50 is located on the side of the support base body 40 opposite to the placement groove 42.

[0026] (Securing band) The fixing band 51 is attached in a ring shape around the support base 4 when viewed from the ship's width direction D2. Both ends of the fixing band 51 are connected by a switching mechanism 50. The fixing band 51 secures the navigating body F, which is positioned in the arrangement groove 42 of the support base 4, to the support base 4 so that it does not fall off. The fixing band 51 is switchable by the switching mechanism 50 between a fixed position P1 that secures the navigating body F and a release position P2 that releases the navigating body F.

[0027] (sensor) Sensor 52 is located in the switching mechanism 50. Sensor 52 detects water pressure. Sensor 52 is electrically connected to the switching mechanism 50. When sensor 52 detects water pressure, the switching mechanism 50 releases the connection at both ends of the fixing band 51, thereby releasing the fixing of the cruising body F.

[0028] (cord body) As shown in Figures 1 to 3, two cables 6 are provided. Each cable 6 is positioned within the rail groove 32 and extends along the rail 3. The cables 6 are wires made of metal such as iron. The cables 6 are connected to the support base 4 by being inserted into the mounting holes 43 of the support base 4. The support base 4 is fixed to the cables 6.

[0029] (Winch) The winch 7 is located on the deck 20 of the hull 2. The winch 7 allows the cable 6 to be extended and stopped. The winch 7 has a roller section 70.

[0030] (Roller section) The roller section 70 is formed in a cylindrical shape extending in the ship's width direction D2. The roller section 70 is rotatable around a rotation axis extending in the ship's width direction D2. The end of the rope 6 is wrapped around the roller section 70. The roller section 70 is rotated by the weight of the rope 6, the support base 4 connected to the rope 6, the fixing part 5, and the cruising body F installed on the support base 4. The roller section 70 is fixed in place by a stopper (not shown) so that it cannot rotate except when the cruising body F is being dropped.

[0031] (Continuous dropping of aircraft) Next, the procedure for the above-mentioned vessel 1 to continuously drop the cruising body F will be explained with reference to Figures 2, 6, and 7. As shown in Figure 2, first, each vehicle F is placed on the support base 4, and the vehicle F is fixed to the support base 4 by the fixing part 5.

[0032] Next, the stopper (not shown) of the winch 7 is released. Then, the weight of the rope 6, the support base 4 connected to the rope 6, the fixing part 5, and the vehicle F fixed to the support base 4 causes the winch 7 to rotate. As a result, the rope 6 wrapped around the roller part 70 of the winch 7 is paid out towards the rear in the direction of travel D1.

[0033] As shown in Figure 6, when the support base 4 reaches the waterline WL, a sensor 52 installed on the fixing part 5 detects the water pressure. Then, the switching mechanism 50 switches the fixing band 51 from the fixed position P1 to the unlocked position P2 (see Figure 5), and the fixing part 5 releases the fixing of the vessel F. Once released, the vessel F is dropped into the water. The vessel F, once dropped into the water, sinks due to its own weight. The support base 4, which has released the vessel F, also sinks into the water while still connected to the rope 6, or floats near the water surface.

[0034] As shown in Figure 7, the second and subsequent vessels F are also dropped into the water in the same manner as the first vessel F that was dropped. Furthermore, since the continuous deployment of the navigating objects F takes place while ship 1 is underway, by the time the next navigating object F is deployed into the water after the previous one has been deployed, ship 1 will have moved far enough away that the navigating objects F will not collide with each other. In this way, the continuous dropping of the aircraft F is carried out smoothly without causing collisions.

[0035] (Effects and Benefits) In this embodiment, the vessel 1 includes a rail 3 that extends vertically along the outer surface 21 and whose lower end reaches the waterline WL, a plurality of support bases 4 that are slidable along the rail 3 and capable of supporting the vessel F, and are provided in the direction of the extension of the rail 3, a rope 6 that extends along the rail 3 and is connected to each support base 4, and a winch 7 provided on the hull 2 ​​that can extend and stop the rope 6.

[0036] The navigating object F is dropped into the water from the ship 1 by its own weight. Furthermore, the support base 4 that supports the navigating object F is supported by the tension of the rope 6. As a result, the ship 1 can continuously drop multiple navigating objects F from the deck 20 while moderately reducing the drop speed of the navigating objects F. Because the drop speed of the navigating objects F is moderately reduced, the impact that the navigating objects F receive from the water surface can be reduced. Furthermore, since the ship 1 can drop the navigating objects F at a moderately low speed while moving on the water surface, each navigating object F can be dropped at a distance from each other. This allows the ship 1 to suppress collisions between the dropped navigating objects F. In this way, the ship 1 can reduce the impact from the water surface and suppress collisions between the navigating objects F, thus suppressing malfunctions of the navigating objects F during drop. Therefore, the ship 1 can continuously drop multiple navigating objects F from the deck 20 without causing any malfunctions.

[0037] In this embodiment, the rail 3 has a deck rail portion 30 that extends from the upper end of the outer surface 21 onto the deck 20.

[0038] This allows the vessel 1 to smoothly move the navigating object F from the deck 20 to the outer surface 21, thereby enabling smoother continuous deployment of the navigating object F. Consequently, the vessel 1 can deploy more navigating objects F per unit time. Furthermore, the operation of supporting the navigating object F on the support base 4 can be performed on the deck 20. This improves the efficiency of the navigating object F deployment operation.

[0039] In this embodiment, the outer surface 21 (stern slope 24) along which the rail 3 follows is formed in a slope shape that gradually moves away from the deck 20 in a straight line horizontally from the upper end toward the waterline WL.

[0040] The rail 3 is installed so as to be inclined along the sloping outer surface 21. As a result, the support base 4 can move downward while receiving a normal force from the rail 3. This allows the ship 1 to suppress the rapid fall of the vessel F towards the water surface. The ship 1 can further reduce the impact that the vessel F receives from the water surface. It can also further suppress collisions between dropped vessels F. Therefore, it can further suppress malfunctions of the vessel F during deployment.

[0041] In this embodiment, the support base 4 has an arrangement groove 42 in which the aerial vehicle F is placed.

[0042] As a result, the support base 4 can suppress the unexpected movement of the vehicle F by the positioning groove 42. Therefore, with a simple configuration, it is possible to prevent the vehicle F from deviating from the support base 4 when it is dropped.

[0043] In this embodiment, the vessel 1 has a fixing part 5 that can be released from the waterline WL, and the vessel 1 fixes the cruising body F to a support base 4.

[0044] As a result, the fixing part 5 prevents the vessel F from being dropped into the water before the support base 4 reaches the waterline WL. Therefore, when the vessel 1 drops the vessel F, it can prevent the vessel F from falling unexpectedly and receiving a strong impact from the water surface. Thus, the vessel 1 can further reduce the risk of the vessel F malfunctioning when it is dropped.

[0045] In this embodiment, the rail 3 is provided at the stern 2b of the hull 2 ​​and extends from the stern 2b to the rear side in the direction of travel D1 of the hull 2.

[0046] As a result, the vessel 1 can drop the vessel F to the rear in the direction of travel D1, and can drop the next vessel F at a position separated from the previously dropped vessel F in the direction of travel D1. Therefore, the vessel 1 can reliably drop each vessel F at a separated position. Thus, the vessel 1 can further reduce the likelihood of collisions between dropped vessels F.

[0047] In the first embodiment described above, the roller section 70 of the winch 7 is driven to rotate by the weight of the cable 6, the support base 4 connected to the cable 6, the fixing part 5, and the vehicle F installed on the support base 4, but it is not limited to this. For example, the roller section 70 may be driven to rotate by human power, or it may be driven to rotate by an electric motor or the like.

[0048] <Second Embodiment> Hereinafter, the vessel 201 according to the second embodiment of this disclosure will be described with reference to Figures 8 and 9. In the second embodiment, components similar to those in the first embodiment are denoted by the same reference numerals as in the first embodiment, and their descriptions are omitted as appropriate.

[0049] As shown in Figures 8 and 9, the support base 204 has a support base body 40, and unlike the first embodiment, the insertion portion 41 is not provided on the side of the support base body 40 opposite to the arrangement groove 42.

[0050] The fixing portion 205 is provided on the side of the support base body 40 opposite to the arrangement groove 42. A pair of fixing portions 205 are provided at both ends of the support base body 40 in the extending direction. The fixing portion 205 has a switching mechanism 50, a fixing band 51, a sensor 52, and a connecting mechanism 253, similar to the first embodiment.

[0051] The connecting mechanism 253 is located on the opposite side of the support base body 40 of the switching mechanism 50. The connecting mechanism 253 is provided to connect the switching mechanism 50 and the cable 6. The connecting mechanism 253 is formed in a cylindrical shape extending in a direction perpendicular to the extending direction of the support base body 40. The cable 6 is fixed in the connecting mechanism 253 with it inserted. The connecting mechanism 253 is formed by two divided parts 254 that are divided in a semi-cylindrical shape along the central axis of the connecting mechanism 253. The connecting mechanism 253 is provided by the switching mechanism 50 so that it can be switched between a connected position P3 and a disconnected position P4. In the connected position P3, the two divided parts 254 are fitted onto the cable 6, and the switching mechanism 50 and the cable 6 are connected. In the disconnected position P4, the two divided parts 254 are separated along the dividing line, and the connection between the switching mechanism 50 and the cable 6 is released. When the switching mechanism 50 detects water pressure using the sensor 52, it switches the coupling mechanism 253 from the coupling position P3 to the uncoupling position P4.

[0052] The fixing section 205 secures the vessel F to the support base 204 by fixing band 51, and also secures the support base 204 to the rope 6 by connecting mechanism 253. In other words, the fixing section 205 secures both the vessel F and the support base 204 to the rope 6. When the fixing section 205 detects water pressure with the sensor 52, it releases both the fixing of the vessel F by fixing band 51 and the fixing of the support base 204 by connecting mechanism 253.

[0053] (Effects and Benefits) In this embodiment, the fixing part 205 fixes the cruising body F and the support base 4 to the cable 6.

[0054] As a result, the fixing part 205 releases the fixing of the support base 204 at the same time as releasing the fixing of the navigating body F, allowing the support base 204 to be dropped into the water along with the navigating body F. Therefore, the support base 204 sinks together with the navigating body F. Compared to the case where the support base 204 remains connected to the rope 6 even after the navigating body F is dropped, the ship 201 can suppress the collision of the next navigating body F that is dropped with the support base 204. Thus, the ship 201 can further suppress the malfunction of the navigating body F during the drop.

[0055] As shown in Figure 10, the fixing part 205 may have a crimping part 255 instead of the connecting mechanism 253. The crimping part 255 has a cylindrical part 255a and a connecting part 255b. The cylindrical part 255a is made of a metal material. The cable 6 is press-fitted into the cylindrical part 255a. That is, the cylindrical part 255a is crimped to the cable 6. The connecting part 255b connects the cylindrical part 255a and the switching mechanism 50. The connecting part 255b is fixed to the outer circumferential surface of the cylindrical part 255a. The connecting part 255b is connected to the switching mechanism 50 in a way that allows it to be disconnected. When the switching mechanism 50 detects water pressure by the sensor 52, the connection between the switching mechanism 50 and the connecting part 255b is released.

[0056] <Third Embodiment> Hereinafter, the vessel 301 according to the third embodiment of this disclosure will be described with reference to Figures 11 and 12. In the third embodiment, components similar to those in the first embodiment are denoted by the same reference numerals as in the first embodiment, and their descriptions are omitted as appropriate. As shown in Figure 11, the rail groove 332 is provided not only on the upper surface of the rail 303, but also on the lower surface of the rail 303, and at the front and rear ends of the rail 303. In other words, the rail groove 332 is provided in an annular shape when viewed from a direction perpendicular to the extending direction of the rail 303 (ship width direction D2).

[0057] The cable 306 is positioned within the rail groove 332 and is provided in a ring shape that surrounds the rail 303 when viewed from a direction perpendicular to the direction of extension of the rail 303 (ship width direction D2). The support base 4 is fixed to the cable 306.

[0058] The winch 307 has a roller section 370 and a drive section 371. The end of the annular cable 306 is hooked onto the roller section 370. The drive unit 371 is a device that rotates the roller unit 370. The drive unit 371 is, for example, an electric motor.

[0059] (Effects and Benefits) In this embodiment, the rope 306 is arranged in an annular shape so as to surround the rail 303 when viewed from the ship's width direction D2. Furthermore, the support base 4 is fixed to the rope 306. The winch 307 has a roller section 370 on which the rope 306 is hooked, and a drive section 371 that rotates the roller section 370.

[0060] As a result, the ship 1 can continuously drop the navigating objects F from the hull 2 ​​until there are no more navigating objects F left, as shown in Figures 11 and 12, by rotating the winch 7 and sequentially placing the navigating objects F onto the support base 4. Therefore, since the navigating objects F can be dropped continuously and efficiently, it becomes possible to drop a larger number of navigating objects F.

[0061] (Other embodiments) Although embodiments of this disclosure have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments and may include design changes and the like that do not depart from the gist of this disclosure. In the above embodiment, the outer surface 21 at the end of the stern 2b is a stern slope 24 that gradually separates linearly from the deck 20 in the horizontal direction toward the rear in the direction of travel D1 as it moves from the upper end toward the waterline WL, but it is not limited to this. The outer surface 21 at the end of the stern 2b may be formed to extend, for example, in the vertical direction.

[0062] In the above embodiment, the rail 3,303 is assumed to have a deck rail portion 30 and an outer rail portion 31, but it is not limited to this. The rail 3,303 may not have a deck rail portion 30 and may have only an outer rail portion 31.

[0063] In the above embodiment, the rail 3,303 is provided at the stern 2b of the hull 2 ​​and extends from the stern 2b to the rear side in the direction of travel D1 of the hull 2, but it is not limited to this. The rail 3,303 may be provided at the bow of the hull 2 ​​and extend to the front side in the direction of travel D1 of the hull 2. Also, if the hull 2 ​​is wide in the width direction D2, the rail 3 may be provided on the side 23 of the hull 2 ​​and extend outward in the width direction D2.

[0064] In the above embodiment, the fixing of the fixing part 5,205 is automatically released when the sensor 52 detects water pressure, but this is not the only option. The fixing of the fixing part 5,205 may also be released by remote operation.

[0065] In the above embodiment, the winch 7,307 is described as being located on the deck 20, but this is not the only possible configuration. The winch 7,307 may also be located inside the hull 2.

[0066] <Note> The vessels 1,201,301 described in each embodiment can be understood, for example, as follows:

[0067] (1) The vessel 1,201,301 according to the first embodiment comprises a hull 2 ​​having a deck 20 and an outer surface 21 connected to the deck 20; a rail 3,303 extending vertically along the outer surface 21 with its lower end reaching the waterline WL; a plurality of support bases 4,204 provided in the direction of extension of the rail 3, which are slidable along the rail 3,303 and capable of supporting a vessel F; a rope 6,306 extending along the rail 3,303 and connected to each of the support bases 4,204; and a winch 7,307 provided on the hull 2 ​​that can extend and stop the rope 6,306.

[0068] The navigating object F is dropped into the water from the ship 1,201,301 by its own weight. Furthermore, the support bases 4,204 that support the navigating object F are supported by the tension of the rope 6,306. As a result, the ship 1,201,301 can continuously drop multiple navigating objects F from the deck 20 while appropriately reducing the dropping speed of the navigating objects F.

[0069] (2) The vessel 1,201,301 of the second embodiment is the vessel 1,201,301 of (1), wherein the rail 3,303 may have a deck rail portion 30 extending from the upper end of the outer surface 21 onto the deck 20.

[0070] This allows the vessels 1,201,301 to smoothly move the vessel F from the deck 20 to the outer surface 21. It also allows the vessels to support the vessel F on the support bases 4,204 on the deck 20.

[0071] (3) The third embodiment of the vessel 1,201,301 is the vessel 1,201,301 of (1) or (2), wherein the outer surface 21 along which the rail 3,303 is laid may be formed in a slope shape that slopes so as to move from the upper end toward the waterline WL, gradually moving away from the deck 20 in a straight line in the horizontal direction.

[0072] The rails 3,303 are installed to be inclined along the sloping outer surface 21. As a result, the support base 4 can move downward while receiving a normal force from the rails 3,303. This allows the vessels 1,201,301 to prevent the vessel F from rapidly falling towards the water surface.

[0073] (4) The vessel 1,201,301 of the fourth embodiment is any of the vessels 1,201,301 of (1) to (3), wherein the support base 4,204 may have an arrangement groove 42 in which the cruising body F is placed.

[0074] As a result, the support base 4,204 can suppress unexpected movement of the vehicle F by the placement groove 42.

[0075] (5) The fifth embodiment of the vessel 1,201,301 is any of the vessels 1,201,301 of (1) to (4) and further comprises a fixing part 5,205 which fixes the cruising body F to the support base 4 and can be released near the waterline WL.

[0076] As a result, the fixing part 5,205 can prevent the vehicle F from being dropped into the water before the support base 4,204 reaches the waterline WL.

[0077] (6) The vessel 201 of the sixth embodiment is the vessel 201 of (5), wherein the fixing part 205 may fix the cruising body F and the support base 204 to the rope 6.

[0078] As a result, the fixing part 205 can release the fixing of the support base 204 at the same time as releasing the fixing of the vehicle F, and drop the support base 204 into the water together with the vehicle F.

[0079] (7) The vessel 1,201,301 of the seventh embodiment is any vessel 1,201,301 of (1) to (6), wherein the rail 3,303 is provided at the stern 2b of the hull 2 ​​and may extend from the stern 2b to the rear side of the hull 2 ​​in the direction of travel D1.

[0080] As a result, ships 1,201,301 can drop the vessel F aft in the direction of travel D1, and can drop the next vessel F at a position separated from the previously dropped vessel F aft in the direction of travel D1.

[0081] (8) The eighth embodiment of the vessel 301 is any vessel 301 of (1) to (7), wherein the rope 306 is provided in an annular shape surrounding the rail 303 when viewed from a direction perpendicular to the extending direction of the rail 303, the support base 4 is fixed to the rope 306, and the winch 307 may have a roller section 370 on which the rope 306 is hooked, and a drive section 371 for rotating the roller section 370.

[0082] As a result, the ship 301 can continuously drop the vessel F from the hull 2 ​​until all vessel F remains, by rotating the winch 307 and sequentially placing the vessel F onto the support base 4. [Explanation of Symbols]
