  As described above, there is a disclosure of a technique for preventing pirates from entering a ship, but there is a demand for the development of a device having a higher pirate intrusion prevention effect.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a pirate intrusion prevention device having a high effect of preventing pirates from entering a ship.

  The apparatus for preventing pirates from entering a ship according to the present invention is characterized in that a baffle plate that forms an angle with respect to the outer skin of the hull is provided around the ship side of the ship.

  According to such a pirate intrusion prevention device for a ship, since the baffle plate is provided at an angle with respect to the hull outer plate around the ship side of the ship, Pirates are difficult to climb, and the intrusion prevention effect can be enhanced.

  Here, if the baffle plate is provided with a drive means that swings up and down about one axis along the ship's edge as a fulcrum, the baffle plate swings up and down by the drive means and appeals to the pirate's vision and attacks. In addition to being able to deceive, pirates can be made more difficult to climb and pirates who want to climb can be shaken off, further enhancing the intrusion prevention effect.

  In addition, since pirates often creep from the back of the ship and climb from the stern, it is effective that the baffle is provided at the stern.

  According to the present invention, the effect of preventing pirates from entering the ship can be enhanced.

It is a perspective view which shows the pirate intrusion prevention apparatus to the ship which concerns on embodiment of this invention. It is a side view of the pirate intrusion prevention device shown in FIG. It is operation | movement explanatory drawing of the pirate intrusion prevention apparatus shown in FIG.1 and FIG.2.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a preferred embodiment of a pirate intrusion prevention apparatus for a ship according to the invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a pirate intrusion prevention apparatus for a ship according to an embodiment of the present invention, FIG. 2 is a side view of the pirate intrusion prevention apparatus, and FIG. 3 is an operation explanatory view of the pirate intrusion prevention apparatus.

  The pirate intrusion prevention device 100 to the ship of this embodiment is intended to prevent the pirates from entering the ship from the sea, and is provided around the ship side of the ship. As shown in FIGS. 1 and 2, the stern 2 of the hull 1 is provided.

  This pirate intrusion prevention device 100 generally includes a baffle plate 3 and a driving means 4 for driving the baffle plate 3.

  The baffle plate 3 is configured as a flat plate, and the base end side (the upper deck 5 side in FIG. 1, the right end side in FIG. 2) is along the ship edge that is the upper edge of the hull 1, here, the ship edge 2 b of the stern 2. It is provided over a wide area.

  As shown in phantom lines in FIG. 2, the baffle plate 3 is in a standby position (stern outer plate 2a) that hangs down so as to face the stern outer plate 2a, which is a hull outer plate, outside the pirate habitat area that is normal. In the pirate habitat sea area, as shown by the solid line in FIGS. 1 and 2, the pirate prevention posture is inclined with an angle with respect to the stern skin 2a (details). Will be described later).

  The driving means 4 extends along the stern 2 of the stern 2b and fixes the base end side of the baffle plate 3 and supports the respective ends of the rotation shaft 4a in a freely rotatable manner. A pair of bearings 4b, 4b provided on the side, a bevel gear 4c fixed to one end of the rotary shaft 4a, and the bevel gear 4c mesh with each other, perpendicular to the axis of the bevel gear 4c and horizontally centered. And a motor 4e as a drive source mounted on the upper deck 5 of the hull 1 with the bevel gear 4d at the tip of the output shaft 4f.

  In the electric motor 4e, the output shaft 4f rotates forward and backward. The rotational driving force of the electric motor 4e is transmitted to the bevel gear 4d, and the rotating direction is changed by 90 ° by the bevel gear 4c meshing with the rotating shaft 4a. As a result, the baffle plate 3 rotates.

  The baffle plate 3 is driven by a forward and reverse rotation of the electric motor 4e, with the axis (one axis) of the rotating shaft 4a serving as a fulcrum, from a standby position of 0 ° to a predetermined angle such as 90 ° or 45 ° with respect to the stern outer plate 2a. Up to an inclination angle (an angle close to MAX 180 °) is configured to be swingable in the vertical direction.

  And in the drive means 4, by using a pair of bevel gears 4c and 4d, the electric motor 4e has a horizontal axis whose output shaft 4f is orthogonal to the rotation shaft 4a extending along the stern 2b of the stern 2. It can arrange | position so that it may face in the direction, and, thereby, the baffle plate 3 can be provided over the wide range of the stern 2b of the stern 2. FIG.

  Here, the drive source is the electric motor 4e, but an actuator such as pneumatic pressure or hydraulic pressure may be used.

  Next, the operation of the pirate intrusion prevention device 100 configured as described above will be described. 3A and 3B are diagrams for explaining the operation of the pirate intrusion prevention device. FIG. 3A is a diagram showing a standby position of the baffle plate, and FIG. 3B is a pirate blocker that inclines the baffle plate with respect to the stern outer plate. It is a figure which shows an attitude | position.

  First, outside the sea area where the pirates appear and disappear during normal times, as shown in FIG. 3A, the baffle plate 3 is set in a standby posture in which it is suspended so as to face the stern outer plate 2a.

  Next, when reaching the pirate infestation sea area, as a countermeasure against pirates, as shown in FIG. 3B, the baffle plate 3 is rotated by a predetermined angle with respect to the stern outer plate 2a by the driving means 4 so that the pirates are difficult to climb. In this state, stop the pirate and lock it in a pirate prevention posture. Here, the baffle plate 3 is rotated by 45 ° with respect to the stern outer plate 2a. However, it may be 90 ° (see FIGS. 1 and 2) or any other angle if the pirate is difficult to climb. .

  And if it goes out of a pirate haunting sea area, the baffle plate 3 will be rotated below by the drive means 4, and it will return to the standby position shown to Fig.3 (a).

  Here, the baffle plate 3 is configured to be rotatable so that the baffle plate 3 does not interfere with the outside of the pirate habitat area. It may be tilted and fixed.

  Thus, in this embodiment, since the baffle plate 3 is provided in the stern 2 around the ship side of the ship so as to form an angle with respect to the stern outer plate 2a, the baffle plate 3 causes the mouse to turn back. Thus, it is difficult for pirates to climb, and the intrusion prevention effect can be enhanced.

  Here, in order to make the anti-piracy measures in the pirate haunting area more effective anti-piracy measures, when the pirate haunting area is reached, the driving means 4 causes the baffle plate 3 to be moved from 0 ° (standby posture) to 90 °, for example. It is also possible to take measures against pirates that swing in the vertical direction within a range of a predetermined inclination angle such as 45 ° (see FIGS. 1, 2, and 3B).

  According to this anti-piracy measure, the baffle plate 3 swings up and down by driving the driving means 4 and can appeal to the pirate's sight and make the assault attack. In addition, the pirates are more difficult to climb and climb. The pirate who is coming can be shaken off, and the intrusion prevention effect can be further enhanced as compared with the baffle plate 3 which is tilted and stopped as described above. Of course, the driving means 4 may have other configurations as long as the rotation shaft 4b can be rotated so that the baffle plate 3 can swing. Incidentally, the rocking referred to here means that the baffle plate 3 repeats vertical movement continuously or intermittently with one axis as a fulcrum.

  Further, according to the present embodiment, there are the following effects. In other words, pirates often creep up from the rear of the ship and climb up from the stern 2, but since the baffle plate 3 is provided on the stern 2 in any of the pirate measures described above, the intrusion prevention effect is high. It has become.

  Although the present invention has been specifically described above based on the embodiment, the present invention is not limited to the above embodiment. For example, in the above embodiment, the baffle plate 3 is described as being particularly effective. Although it is provided at the stern 2, it can be provided around the ship side including the stern, the middle part, and the bow. Therefore, the baffle plate 3 is provided around the ship side of the ship so as to form an angle with the hull outer plate in a broad sense.
