Further, since the motion performance of the towed target boat 51 is limited to the motion performance of the tug boat 52 and the motion performance of the target boat 51 to be towed by this, the torpedo boat and the small missile boat that are the original targets. It is not possible to adequately simulate the motion performance of large surface ships.
[0007]
The towed target boat 51 must be towed between the port and the training area.
[0008]
Furthermore, in the windy sea, the sail 55 for visual recognition lifted on the deck 54 of the target boat 51 is subjected to a crosswind, which affects the movement of the target boat 51 and makes it difficult for the tug boat 52 to tow as desired. There is.
[0009]
On the other hand, when using a self-propelled target boat that is remotely controlled by a radio control, there is no fear of shooting a tugboat for towing, and it is possible to accurately simulate the performance of a torpedo boat, etc. Become.
[0010]
However, even with such a self-propelled target boat, it is not easy to transfer between the port and the training area. Especially when the target boat is hit and damaged during shooting training, the damaged target boat is towed to the port. This requires a lot of time and effort. In addition, as a result of the crosswind of the sail on the deck of the target boat, the remote control of the target boat by the radio control is not adversely affected by the towed target boat 51.
[0011]
The present invention pays attention to such problems, and has sufficient exercise performance as a target boat, and can easily carry out unmanned slinging operations at the time of entering into the sea and at the time of landing on the containment vessel. Aims to provide the right target boat.
[0012]
[Means for Solving the Problems]

It is characterized by that.
[0013]
According to a second aspect of the present invention, the fitting member is a sphere, and a recess is formed on the lower surface of the receiving member to which the sphere is fitted, and the rope extending from the sphere fitted in the recess is released upward by a guide groove. It is characterized by doing so.
[0014]
In a third aspect of the invention, the receiving member is provided at a position that substantially coincides with the position of the center of gravity of the target boat.
[0015]
In a fourth aspect of the present invention, the guide means is a curved rod-like member that extends laterally from the receiving member.
[0016]
The fifth invention includes a sail having a plurality of slits formed at predetermined intervals.
[0017]
According to a sixth aspect of the present invention, there is provided locking means capable of locking an anchor on the bow and stern of the target boat.
[0018]
According to a seventh aspect of the invention, the locking means has a structure in which a bar-like member protruding from the bow and stern is framed.
[0019]
[Action]
In the first invention, since the target boat is remotely controlled by a radio control, its movement performance is high and suitable for shooting training, and it is safe without accidentally shooting a tug boat for towing during shooting training. while is increased, launch and recovery of the on and accommodate vessels to sea target boat, the rope extending from the deck crane provided in the housing ship, the guide means and the guide groove and is guided to the center of the deck of the target boat When the fitting member held on the rope reaches the receiving member, and the fitting member held at the tip of the rope is fitted to the receiving member, the target boat is lifted upward by pulling up the rope. If the target boat is housed in the containment vessel in this way, the transfer of the target boat between the port and the training area can be carried out quickly by the containment vessel. It can be easily performed, in particular labor and time significantly reduces the transfer operations such as when the target boat is damaged.
[0020]
In the second invention, the sphere at the tip of the rope is fitted from below into the recess formed in the receiving member, but this rope is released upward from the guide groove formed in the receiving member, and when the target boat is pulled up by the rope Since the sphere is lifted upward by the rope, the concave portion of the receiving member and the sphere are pressed against each other to strengthen the coupling by fitting, so that the target boat is stably lifted upward by the rope.
[0021]
In the third invention, since the receiving member is provided at a position substantially coincident with the position of the center of gravity of the target boat, the target boat is tilted forward, backward, left and right with respect to the receiving member as a fulcrum when the target boat is thrown in or out. The target boat can be thrown in and out easily because it is stably lifted upward while being balanced.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0027]
FIG. 1 shows an overall view of a target boat of the present invention.
[0028]
This target boat 1 is a self-propelled unmanned boat with an FRP structure equipped with an engine and fuel, and is remotely controlled by a radio control. The target boat 1 is also provided with a steering handle and a forward / reverse lever for manual operation, and can switch from a radio control operation to a manned manual operation by a switch operation in the boat, and can cope with manned manual operation mainly during adjustment. It is like that.
[0029]
At the center of the deck 2 of the target boat 1, a tower 3 is fixed for lifting when the target boat 1 is collected in the containment vessel.
[0030]
This tower 3 has a structure in which a plate-shaped tower body 6 is supported at the tips of a total of four pillars 4 and 5 extending from the left and right heel sides, and the center of gravity of the tower 3 is just the target boat 1. It is arranged so as to be near the center of gravity of the whole.
[0031]
Of these struts 4 and 5, the left and right struts 4 on the front side (the bow side) serve as a guide means for the wire rope 21 extending from a deck crane (not shown), and are curved forward to draw the arc while drawing the arc. Guide horns 7 and 8 made of a substantially V-shaped metal pipe projecting in the direction are fixed. The guide horns 7 and 8 are a pair of upper and lower, and a total of four are provided.
[0032]
A net 9 is stretched between the upper guide horn 7 and the lower guide horn 8, and this net 9 wraps around the back of the tower body 6 so as to cover the entire bottom of the tower body 6. Yes.
[0033]
A notch portion 11 having a predetermined width is formed from the end of the tower body 6 on the bow side toward the center of the tower body 6 at the center innermost portion of the upper pair of guide horns 7. The notch 11 communicates with a circular hole 12 formed in the center of the tower body 6. As shown in FIGS. 2 to 4, a cylindrical catcher 13 that is a receiving member into which a ball 23 that is a fitting member described later is fitted is fitted into the circular hole 12 from below.
[0034]
The catcher 13 has a diameter substantially equal to that of the circular hole 12 and is provided with an annular flange portion 14 projecting sideways on the lower surface side. It attaches to the back surface of this via a plurality of bolts 15. In this case, since the flange portion 14 is in sliding contact with the back surface side of the tower body 6 and the plurality of bolts 15 press the catcher 13 from below, the joining strength between the catcher 13 and the tower body 6 is strong against the force received from below. It has become.
[0035]
On the lower surface side of the catcher 13, a receiving portion 16 that is a concave (hemispherical) depression (concave portion) is formed. Further, as shown in FIG. 4, a guide groove 17 is formed from the side surface of the catcher 13 on the side of the notch portion 11 of the tower body 6 to the space of the small cylinder that is coaxial with the catcher 13.
[0036]
As a result, a passage extending from the notch portion 11 to the guide groove 17 is opened in front of the tower main body 6, and this passage includes a deck crane (not shown) provided in a receiving vessel that accommodates the target boat 1 during transfer. As a result of the wire rope 21 extending from the guide groove 17 being guided between the deepest portions of the guide groove 17, a ball connected to the end of the wire rope 21 below the end fitting 22 via a bolt 24 and a nut 25. 23 is led to the receiving portion 16.
[0037]
The ball 23 guided to the receiving portion 16 is moved upward by pulling up the wire rope 21 so as to be fitted into the receiving portion 16. At this time, the ball 23 and the receiving portion 16 are completely connected. The ball 23 has a spherical shape on the upper side, and the diameter of the ball 23 is slightly smaller than the diameter of the hemisphere forming the receiving portion 16.
[0038]
After the ball 23 and the receiving portion 16 are thus fitted, if the wire rope 21 is further lifted by the deck crane of the containment ship, the fitting of the ball 23 and the receiving portion 16 is firmly performed by the weight of the target boat 1. As a result, the target boat 1 can be stably lifted upward, so that the target boat 1 can be thrown into the sea and can be lifted into the containment vessel with a deck crane.
[0039]
On the other hand, a columnar mast (main column) 26 is fixed vertically on the stern side of the deck 3 of the target boat 1. The mast 26 is fixed to the deck 3 side by a stay wire rope 27, and the mast 26 is firmly held on the deck 3 side so as not to fall down. On the top of the mast 26, a radar reflector 28 that is a target for radar shooting is installed.
[0040]
Near the lower end of the mast 26, a boom 31 on the pipe is provided sideways, and a visual sail 32 made of a straight nylon canvas is stretched between the mast 26 and the boom 31. At this time, the boom 31 is pulled by a rope to a stern split 36, which will be described later, so as not to flutter.
[0041]
A hydraulic winch (not shown) is built in the mast 26. By this hydraulic winch, a rope (not shown) connected to the sail 32 is slid through a pulley in the boom, so that the sail 32 can be automatically stretched or folded.
[0042]
In addition, a plurality of slits 33 are formed in the sail 32 at a predetermined interval, and crosswinds at sea can escape to the back side of the sail 32 through the slits 33.
[0043]
The bow of the target boat 1 has a bow split 35 made of a curved metal pipe frame, while the stern has a stern split 36 made of a curved metal pipe frame similar to the bow split 35, respectively. Protrusively fixed. An anchor 37 (towed anchor or lock anchor) can be easily hooked on the pipe-shaped frame of the bow split 35 and the stern split 36, and it becomes a locking means for locking the anchor 37. By operating the extending rope 38 to control the position of the bow and stern of the target boat 1, the direction of the target boat 1 can be controlled and the swing can be stopped.
[0044]
A band-like rubber bag 39 is attached to the shore side of the target boat 1 so as to surround the hull. The rubber bag 39 filled with air protects the heel side of the target boat 1 and prevents the target boat 1 from overturning.
[0045]
Next, the operation will be described.
[0046]
When the target boat 1 of the present invention is used for shooting training at sea, the ball 23 at the tip of the wire rope 21 extending from the deck crane is fitted to the catcher 13 of the target boat 1 accommodated in the containment vessel, and then the deck. The crane is operated and the target boat 1 is thrown into the sea. When the target boat 1 reaches the sea, if the wire rope 21 is further pulled out from the deck crane, the unsupported ball 23 will come off from the receiving portion 16 of the catcher 13, so the deck crane is swung here. If the wire rope 21 is moved through the guide groove 17 and the notch 11 and pulled away from the target boat 1, the insertion of the target boat 1 into the sea is completed.
[0047]
Thus, the target boat 1 thrown into the sea is used for shooting training, but since this target boat 1 is remotely controlled by a radio control, its motion performance is high, and the motion performance of the torpedo boat etc. that is the original target is high. It can be simulated accurately.
[0048]
In addition, since there is no need to arrange a tugboat for towing on the target boat 1 side with respect to a ship that performs shooting (not shown), there is no risk that the ship that performs shooting will fire the tugboat by mistake.
[0049]
Further, a sail 32 for visual recognition is lifted behind the deck 2 of the target boat 1 so that the target boat 1 can be easily recognized from a distant ship, but the cross wind received by the sail 32 is received by the slit 33. Can be escaped to the back side of the sail 32 and the wobbling due to the crosswind of the target boat 1 can be suppressed, so that the movement performance of the target boat 1 is not adversely affected. The sail 32 can be expanded and contracted by remote operation, and the influence of cross wind can be avoided by adjusting the degree of expansion and contraction.
[0050]
When the target boat 1 is accommodated in the containment vessel after the completion of the shooting training, the deck crane is operated again, and the ball 23 at the tip of the wire rope 21 extending from the deck crane is placed at a predetermined height on the sea near the target boat 1. Hang it. Subsequently, the target boat 1 is steered toward the wire rope 21 at a low speed, and the wire rope 21 and the ball 23 at the tip thereof are guided between the left and right guide horns 7 and 8.
[0051]
As shown in FIG. 4, the wire rope 21 guided between the guide horns 7 and 8 is guided inside the curved arm of either the left or right upper guide horn 7 (in this case, the right guide horn 7). In spite of this, as the target boat 1 moves, it moves to the notch 11 of the tower body 6. As a result, the wire rope 21 is guided from the notch 11 to the guide groove 17 of the catcher 13.
[0052]
In accordance with such movement, the ball 23 at the tip of the wire rope 21 moves while being supported by the net 9 between the upper guide horn 7 and the lower guide horn 8 and finally below the receiving portion 16 of the catcher 13. It is arranged. During this time, since the ball 23 is wrapped by the net 9, the ball 23 is not shaken and collides with the target boat 1 body.
[0053]
Now, if the target boat 1 is stopped in this state and the wire rope 21 of the deck crane is pulled up, the ball 23 is fitted into the receiving portion 16 of the catcher 13, and the target boat 1 is lifted from the sea and moved to the containment boat. Easily accommodated.
[0054]
In addition, when the target boat 1 is lifted by the deck crane in the above-described loading and lifting operations of the target boat 1, the tower 3 on which the catcher 13 serving as a fulcrum is installed is substantially at the center of gravity of the target boat 1. Therefore, the target boat 1 does not tilt forward, backward, left and right with respect to the catcher 13, and is stably lifted upward while being balanced, so that the target boat 1 can be easily thrown in and out.
[0055]
In such loading and unloading work of the target boat 1, the rope 38 extending from the anchor 37 hooked on the bow split 35 and the stern split 36 of the target boat 1 is controlled, so that the posture of the target boat 1 is controlled by the containment boat. It can be easily controlled from the deck.
[0056]
As described above, according to the present invention, the target boat 1 is thrown in and out by the deck crane, and the target boat 1 can be easily received and transferred to the receiving vessel. The waste of time for transferring the boat 1 by towing is eliminated. In addition, since the connection between the deck crane and the target boat 1 is automatically performed when the catcher 13 and the ball 23 are fitted, the deck crane and the target boat 1 are automatically operated only by the operation of the deck crane. In fact, work efficiency is remarkably improved. Furthermore, even when the target boat 1 is damaged, the target boat 1 can be easily picked up.
[0057]

On the other hand, the safety of the target boat can be increased when the target boat is thrown into the sea and lifted to the containment vessel. The rope extending from the deck crane provided in the containment vessel is guided by the guide means and the guide groove, and the deck of the target boat is obtained. When the fitting member held at the tip of the rope is fitted to the receiving member, the target boat is pulled upward by pulling up the rope. It can be easily performed by simply operating the deck crane without going through a slinging operation.If the target boat is housed in the containment vessel in this way, the transfer of the target boat between the port and the training area is facilitated by the containment vessel. And it can be easily performed, in particular labor and time significantly reduces the transfer operations such as when the target boat is damaged.
[0058]
According to the second invention, the sphere at the tip of the rope is fitted from below into the recess formed in the receiving member, but this rope is released upward from the guide groove formed in the receiving member, and the target boat is When pulling up, since the sphere is lifted upward by the rope, the concave portion of the receiving member and the sphere are pressed against each other to strengthen the coupling by fitting, so that the target boat is stably lifted upward by the rope.
[0059]
According to the third aspect of the invention, since the receiving member is provided at a position that substantially coincides with the center of gravity of the target boat, when the target boat is inserted or lifted, the target boat is front, rear, left and right with respect to the receiving member that is a fulcrum. The target boat is easily thrown in and out, so that the target boat can be lifted up stably while being balanced.
[0060]
According to the fourth invention, the rope is stably guided from the side of the receiving member to the receiving member along the rod-shaped member while being supported by the curvature of the rod-shaped member. Is released below the rod-shaped member, so that the rod-shaped member does not interfere with the track of the fitting member and is stably guided below the receiving member.
[0061]
According to the fifth invention, a sail is raised on the target boat, and the target boat can be easily recognized from a distant ship that conducts shooting practice. Since the slit is formed, the crosswind received by the sail can be released to the back side of the sail, and the wobbling due to the crosswind of the target boat can be suppressed, so that the movement performance of the target boat is not adversely affected.
