[0001] The present invention relates to a surface floating object capture ship that efficiently captures floating objects on the water surface, a surface floating object landing system consisting of the surface floating object capture ship, a transport ship and heavy equipment, and a surface floating object capture mechanism mounted on the surface floating object capture ship. [Background technology]

[0002] Fig. 6 is a side view showing the prior art shown in Japanese Utility Model Application Publication No. 61-102626. This invention relates to a device that uses a work vessel 1 equipped with a wire mesh chain conveyor 4 arranged at an angle with its front end submerged in the water surface, and a transport vessel 2 that can be detached from the work vessel 1, and loads the object to be removed A floating on the water surface onto the transport vessel 2 with the wire mesh chain conveyor 4.

[0006] Utility Model Patent Document 2: Utility Model Application 53-65974 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the conventional techniques have the following problems.

[0008] For example, driftwood flowing into a dam comes in all sizes, and there are many floating giant trees that are over 10 meters long. When trying to capture these giant trees using the conventional electric transport method, especially when the driftwood's central axis is parallel to the transport direction, the driftwood storage length inside the ship needs to be longer than the size of the driftwood. In addition, there is a problem that if the length of the driftwood exceeds the storage length, it cannot be captured in the first place.

[0009] Furthermore, if the center of gravity of the driftwood is shifted from the transport surface of the electric transport device, the behavior of the driftwood during transport becomes unstable, and sometimes the driftwood loses balance and falls into the water. Furthermore, the electric transport device system has the problem that it is difficult to align the driftwood and load it onto the transport ship, which reduces the efficiency of the loading space of the transport ship.

[0010] The present invention has been made to solve such problems in a new way, and its purpose is to organize floating objects on the water surface, such as driftwood of various lengths and sizes, in such a way that their axes are aligned and they can be loaded onto a transport ship, and the length of the driftwood can be adjusted as needed, thereby efficiently landing objects floating on the water surface. [Means for solving the problem]

[0011] The present invention provides a water surface floating object capture ship comprising a drive source, a towing rope towed by the drive source, a tension direction changer for changing the tension direction of the towing rope, an arm that rotates by the tension applied to the towing rope, a wobble suppression mechanism for suppressing wobble of the arm, a capture unit swingably supported on the arm, and a holding / release mechanism for holding or releasing an object captured by the capture unit. Also, the present invention provides a water surface floating object landing system comprising the water surface floating object capture ship, a transport ship, and heavy machinery. Effect of the Invention

[0012] The present invention provides advantageous effects.

[0013] It is possible to arrange floating objects on the water surface, such as driftwood, in an aligned state and load them onto a transport ship, improving loading efficiency. In addition, since the capture section is open on the port and starboard sides, it is possible to adjust the length of the driftwood with a chainsaw or other device as needed and load it. Furthermore, it is possible to capture large driftwood that cannot be captured by human power. Furthermore, since the capture and transport functions are separate, for example, two transport ships can be used, and driftwood can be efficiently landed by alternating between loading on one ship and transporting on the other.

[0015] Fig. 1 is a side view of the capture ship 010 of the present invention. Fig. 2 is a perspective view of the capture ship 010 of the present invention. The capture ship 010 will be described below with reference to Figs.

[0016] The arm 004 has a U-shape and is disposed so as to surround the exterior of the bow and starboard and port sides of the capture vessel 010. The arm 004 is rotatably held at a rotation center 017 having an axis of rotation parallel to the starboard and port sides. A mooring part 015 is provided on the bow side of the arm 004, and one end of a towing rope 002 is moored to the mooring part 015, and the other end of the towing rope 002 is connected to a winch 001 via a pulley 003 for changing the direction of tension.

[0017] As a result, when the winch 001 is driven in the winding direction and tension is generated in the towing rope 002, the mooring part 015 receives an upward force and the arm 004 rotates to the right in the drawing (hereinafter referred to as the holding position). On the other hand, when the winch 001 is driven in the slackening direction, the arm 004 rotates to the left in the drawing due to its own weight (hereinafter referred to as the capturing position). The range of motion of the arm 004 is from the capturing position (approximately 1 meter below the water surface) to the holding position (approximately 2 meters above the water surface).

[0018] In order to increase the tension of the towing rope 002, it is effective to provide, for example, a movable pulley or a reduction mechanism. The towing rope 002 is not limited to metal wire, and may be made of any material that can withstand tension, such as Kevlar string or carbon fiber string. The winch 001 can be replaced by a motor, a plunger, or other power source. It is also effective to install an energy generating device, such as a generator, that supplies energy to operate the power source.

[0019] The capture vessel 010 is equipped with a stabilizer 005. One end of the stabilizer 005 is fixed to the hull, and the other end is rotatably engaged with the arm 004 to suppress wobbling of the tip of the arm 004.

[0020] The capturing part 006 is located at the tip of the bow of the arm 004. The capturing part 006 is held to be able to swing about a swing center 013 having a rotation axis parallel to the starboard and port sides. The capturing part 006 has an L-shape stretched in the starboard and port sides, and can take a position where the bottom surface is inclined so that an object on the capturing part 006 can slide off (hereinafter referred to as the "slide-allowing position"), and a position where the bottom surface is inclined so that the object does not slide off (hereinafter referred to as the "non-slide-allowing position"). When capturing driftwood 009 or the like floating on the water surface, the bottom surface of the capturing part 006 is almost horizontal.

[0021] The capture vessel 010 has a holding and releasing mechanism. The capture part 006 has an engagement part 014 at the vertically rising part of the L-shape, and a release lever 007 near the steering position. The engagement part 014 and the release lever 007 are connected by a connecting rod 008. When the release lever 007 is tilted toward the stern and reaches a certain position, a force is generated in the release lever 007 to rotate it clockwise toward the paper surface, and the catch part 006 is mechanically locked in a position where it cannot slide down. At the same time, a part of the release lever 007 hits a stopper (not shown) and stops moving.

[0022] On the other hand, when the release lever 007 is tilted toward the bow and reaches a certain position, a counterclockwise rotating force is applied to the release lever 007 toward the paper surface, the mechanical lock is released, and the catching part 006 transitions to a position where it can slide down due to its own weight. At the same time, a part of the release lever 007 hits a stopper (not shown) and stops moving. This allows the catching part 006 to freely hold or drop objects such as driftwood 009.

[0023] In addition, the catching unit 006 is open on the right and port sides, making it possible to scoop up long driftwood 009 that exceeds the width of the hull. In addition, after the long driftwood 009 has been scooped up by the catching unit 006, it can be cut on the left and right sides of the catching unit 006 with a chainsaw or the like as necessary to adjust it to an appropriate length.

[0024] The capture unit 006 has a lattice-like structure, and when driftwood 009 or the like floating on the water surface is captured, the water scooped up together with the driftwood 009 or the like falls through the gaps in the lattice, and the driftwood 009 or the like is separated from the water.

[0025] The operation of the capturing ship 010 will be explained below with reference to Figures 1, 3 and 4, taking as an example the case of a floating object on the water surface, particularly a driftwood 009. Figures 1, 3 and 4 respectively show the state of the capturing ship 010 at the time of capturing, the state of the capturing ship 010 at the time of holding, and the state of the capturing ship 010 and the transport ship 011 at the time of releasing.

[0026] As shown in Fig. 1, with the capturing unit 006 held in the non-slip position and the arm 004 held in the capturing position, the capturing ship 010 is advanced toward the side of the driftwood 009 floating on the water surface. Once the driftwood 009 is within the capturing unit 006, the position of the arm 004 is transitioned to the holding position, as shown in Fig. 3, and the driftwood 009 is scooped up and held from the water surface 016. While maintaining this state, as shown in Fig. 4, the capturing ship 010 is advanced toward the starboard or port side of the carrier ship 011, bringing the two ships close to each other. At this time, the capturing unit 006 and the driftwood 009 captured by it are positioned on the hull of the carrier ship 011.

[0027] Next, the position of the capture unit 006 is shifted to a position where it can slide down. As a result, the driftwood 009 falls onto the transport ship 011 due to its own weight. At this time, when multiple pieces of driftwood 009 are to be collected in several movements, it is essential to adjust the central axes of the pieces of driftwood 009 so that they are parallel. Also, a mat 018 for lifting by a crane is laid in advance at the position where the driftwood 009 will fall, so that the driftwood 009 will fall onto this.

[0028] Next, the process of unloading the driftwood 009 loaded on the transport ship 011 will be described with reference to FIG.

[0029] 5 is a perspective view showing the transport ship 011 and the crane 012. When the load on the transport ship 011 reaches the target weight, the transport ship 011 is moved to the landing position where the crane 012 is located, and the crane hook 020 is hooked onto the rings 019 connected to the four corners of the mokko 018, which is then hoisted up, and the driftwood 009 is landed on land.

[0030] The floating objects on the water surface are not limited to the driftwood 009, but may be, for example, water plants or garbage. [Industrial Applicability]

[0031] This invention can be used to capture floating objects of various sizes, especially driftwood, that float on the water surface. It is possible to efficiently clean the water surfaces of dams, rivers, oceans, lakes, ponds, etc. [Explanation of symbols]
