Description

Intrusion Prevention Device for Ships {INVASION PREVENTING APPARATUS FOR SHIP}

The present invention relates to a marine intrusion prevention device which is installed around the upper deck and operates by supplying fluid and prevents intrusion of illegal intruders.

In recent years, pirates (illegal intruders) appearing in the Indian Ocean have become a social problem, and the appearance of pirates has become a major obstacle to the safe navigation of ships. Pirates use small boats capable of navigating at high speeds, approaching the ships that are attacked, throwing anchors attached to ropes from starboard, port or tail, etc. onto the upper deck and invading them through ladders. . Pirates who invade ships may demand hostages for large amounts of ransom.

It is also conceivable to prevent such invasion by pirates from being attacked by a plurality of crew members, but this is not preferable because the crew members are exposed to danger. Therefore, a device capable of repelling a pirate without exposing the crew to the pirate, that is, a device that prevents the intrusion of a pirate into a ship has been developed. For example, the method by acoustic, light ray, and electricity, and the method of installing the barbed wire or the large intrusion prevention wall which physically prevent intrusion are mentioned. However, the former can be easily countered by earplugs, sunglasses, rubber gloves, etc., and the latter may be damaged by strong shaking during navigation, and both have decisive problems. Therefore, there is a demand for the development of a device that can effectively prevent pirates from invading and can be easily installed on existing vessels.

On the other hand, in cargo ships etc., seawater pumps, such as a fire extinguishing pump and an emergency fire pump, are provided by ship facility regulation. In large cargo ships and the like, a large amount of seawater is injected into a ballast tank with a large seawater pump (ballast pump), and the weight of the ship is stabilized when there is no load. That is, since the ship is provided with an environment in which seawater can be freely used, the vessel can be installed on an existing ship relatively easily by using an apparatus using seawater (water).

As an apparatus using such seawater, the technique of patent document 1 is known, for example. The illegal boarding prevention device (ship intrusion prevention device) to the ship of patent document 1 is equipped with the trigger which a pirate acts by throwing the anchor etc. which attached the rope to the upper deck. Therefore, hot water (sea water) manufactured in an engine room is sprayed outboard by operation of a trigger. As a result, the pirates who invade the ship are repelled.

Japanese Patent Laid-Open No. 2002-037179 (Fig. 1)

However, the intrusion prevention apparatus for ships described in patent document 1 employ | adopts the structure which operates by a pirate approaching a ship and throwing the anchor etc. which attached a rope to the upper deck. Thus, pirates can easily access the ship, and the ship is exposed to the fear of pirates. Therefore, the idea of keeping the pirates from approaching the ship is desired, for example, if the pirate is looking at the ship from a distance, if it can be seen that he is against the pirate, it lowers the pirate's motivation, It is possible for the ship to reduce the probability of being exposed to the fear of pirates.

An object of the present invention is to provide an intrusion prevention apparatus for ships which can be easily installed on existing vessels and which can be more feared by illegal intruders.

The intrusion prevention apparatus for ships of this invention is installed around the upper deck of a ship, and operates by supplying a fluid, The intrusion prevention apparatus for ships which prevents invasion of illegal intruders WHEREIN: The base end side is provided in the fluid piping provided in the said upper deck.

Here, as shown in Figs. 1A and 2, the bow side is provided with a flare 19 having a shape that is extended upward, and the bow side is left and right by adjusting the height of the ship 10. It is possible to shake greatly. That is, pirates rarely invade the player's side, and therefore, the pirate's intrusion prevention device is not provided.

Hereinafter, the detailed structure of each pirate intrusion prevention apparatus 18a-18f is demonstrated in detail using drawing. Here, since each pirate intrusion prevention apparatus 18a-18f has the same structure, only the pirate intrusion prevention apparatus 18a is demonstrated in detail using drawing.

FIG. 3 is a partially enlarged view for explaining the detailed structure of the pirate intrusion prevention apparatus, FIG. 4 is an explanatory view for explaining the detailed structure and operation state of the Avare hose, and FIG. 5 is a connecting rod and a weight member. 6 (a) and 6 (b) are plan views showing the bulk waterproof nozzle 40, and FIG. 7 is a connection structure between the bulk waterproof nozzle 40 and the rotary joint. FIG. 8 is an explanatory view for explaining an operation state of the bulk waterproof nozzle 40, respectively.

As shown in Fig. 3, the pirate intrusion prevention apparatus 18a includes a plurality of I-shaped pipes (fluid pipes) 20 having two connection parts, and a plurality of T-shaped pipes (fluid pipes) having three connection parts. (21) is provided. Each I-shaped piping 20 and each T-shaped piping 21 are connected by tightening the nut member 22 which can be operated manually, respectively. One end side of each connected I-shaped pipe 21 and each T-shaped pipe 22 is connected to the seawater discharge valve 17a, and the other end side is closed by an end cap (not shown).

Each T-shaped pipe 21 is provided with branch paths 21a, respectively. Each of these branching passages 21a is provided with fitting seams 21b, and the fitting seams 21b are seawater (water) as a fluid to the Avare hose 30 and the bulk waterproof nozzle 40 described later. One end side of the supply hose 23 for supplying W (refer to FIGS. 4 and 8) is connected by fitting.

Between the proximal end side of the Avare hose 30 (bulk waterproof nozzle 40) and the other end side of the supply hose 23, from the supply hose 23 side, the waterproof pressure regulating valve 24 and the pressure gauge 25 ), An angle conversion elbow 26 and a rotary joint 27 are provided. The waterproof pressure regulating valve 24 adjusts the amount and the water pressure of the seawater W sprayed from the Avare hose 30 (the bulk waterproof nozzle 40), while the operator looks at the pressure gauge 25 and the waterproof pressure regulating valve 24 ) Can be operated.

The angle conversion elbow 26 converts the direction of the supply hose 23 and the direction of the Avare hose 30 (bulk waterproof nozzle 40) by approximately 45 °, thereby converting the Avare hose 30 (bulk waterproof). The nozzle 40 is directed toward the freeboard portion of the vessel 10 around the upper deck 13. The rotary joint 27 supports the proximal end side of the abare hose 30 (bulk waterproof nozzle 40) to be rotatable.

As shown in FIG. 1 and FIG. 2, the front end side of the Avare hose 30 is arranged in the freeboard portion around the upper deck 13 so as to face the sea surface (water surface). The Avare hose 30 sprays seawater W with a water quantity of 5 m 3 / h and a water pressure of 0.2 Mpa through the seawater discharge valve 17a (see FIG. 3), and in the forward, backward, leftward and rightward directions at the freeboard portion of the vessel 10. Irregular rocking motion is made (see the thick curve in Figs. 1 and 2).

As shown in Fig. 4, the Avare hose 30 includes a hose member 32 (hose) having flexibility, and a rotational joint 27 on the proximal side (upper side in the drawing) of the hose member 32. (Refer to FIG. 3), an attachment 31 is pivotally connected. Moreover, the nozzle (swing nozzle) 33 which has the injection hole 33a is provided in the front end side of the hose member 32. As shown in FIG.

The length of the hose member 32 is set to 7.0 m in this embodiment, and the length of this hose member 32 is set to the length shorter than 8.0 m of the height of the freeboard part of the ship 10. As a result, the Abaret hose 30 is capable of irregularly swinging forward, backward, left and right in the freeboard portion of the vessel 10. As the hose member 32, for example, a fire hose in which polyester fibers are knitted and formed and coated with a polyester resin is used. As a result, it is possible to realize the low cost of the Abare hose 30 and to provide the hose member 32 having both flexibility and durability.

On the proximal end side of the hose member 32, a protective member 34 for protecting the connection portion of the hose member 32 with the attachment 31 is mounted. The protection member 34 is formed in the shape of a cylinder by, for example, a resin material such as plastic, and is slightly deformed with a spring property in response to the swinging motion of the hose member 32. As a result, excessive force (large bending force) is suppressed from being applied to the connection portion of the hose member 32 with the attachment 31. Here, it is also possible to adjust the swing width of the hose member 32 by appropriately adjusting the length of the protective member 34.

The weight member 36 is attached to the nozzle 33 via the connecting rod 35. One end of the connecting rod is rotatably connected to the nozzle through a pin, and the discoid weight member 36 is rotatably connected to the other end of the connecting rod via a pin. That is, the connecting rod is swingably installed between the nozzle and the weight member 36, whereby the weight member 36 is more complicated and irregularly rocking motion against the irregular rocking motion of the hose member 32.

The weight member 36 is formed in the shape of a disk having a diameter of 7.0 cm and a weight of 1.0 kg, for example, by cutting a block-shaped steel material. In addition, the weight member 36 can be confirmed from a distance, and in order to make the weight member 36 more visible from a distance, it may be colored with white, yellow, fluorescent colors, or the like.

Here, the weight member 36 is balanced with the thrust by the seawater W injected from the injection hole 33a, in addition to the function of making it easy to check from a distance, and the swing width in the front, rear, left and right directions on the tip side of the hose member 32 is increased. It has a function to adjust (regulate). On the contrary, when the weight member 36 is not provided, the control of the tip side of the hose member 32 becomes difficult, for example, the tip side of the hose member 32 is shaken by a large swing width, and the upper deck of the ship 10 ( 13) may be lifted up momentarily.

As shown in Fig. 5, a hose connecting portion 33b for connecting the tip side of the hose member 32 is provided at the proximal end of the nozzle 33, and a pin 35a is mounted at the distal end side of the nozzle 33. The pin mounting hole 33c is provided. A jetting hole for spraying seawater W (see FIG. 4) flowing out of the hose member 32 between the hose connecting portion 33b and the pin mounting hole 33c along the longitudinal direction of the nozzle 33 (up and down in the drawing). 33a is provided.

The inclination angle with respect to the nozzle 33 of the injection hole 33a is set to 60 degrees toward the attachment 31 side (upper side in drawing) along the longitudinal direction of the nozzle 33. Thereby, the thrust by the seawater W injected from the injection hole 33a acts in the direction which oscillates the hose member 32 hanged in the freeboard part of the ship 10. As shown in FIG. Here, the inclination angle of the injection hole 33a is set at an angle capable of generating a thrust for rocking the tip side of the hose member 32. In the nozzle 33 of this structure, the inclination angle of the injection hole 33a is set so that the injection angle may be about 15 degrees-90 degrees, and it is possible to make the front end side of the hose member 32 rocking motion favorable.

If the spray angle is made smaller than 15 °, the seawater W injected from the injection hole 33a will not hit the hose member 32, and the designed thrust will not be obtained. h, it is impossible to oscillate with a fluctuation width of 5.0 m in one direction from the front, rear, left and right directions with a hydraulic pressure of 0.2 MPa. On the other hand, when the injection angle is made larger than 90 °, thrust pushing upwards in the drawing occurs on the front end side of the hose member 32, which also makes it impossible to swing the hose member 32 to the reference swing width.

The bulk waterproof nozzle 40 (waterproof nozzle) sprays a large amount of seawater W toward the sea surface, and as shown in Figs. 6 and 7, the main body cylinder 41 and the nozzle head 42 are provided. A female threaded portion 41a for screwing into the male threaded portion 27a of the rotary joint 27 is provided at one end side in the longitudinal direction of the main body portion 41 (right side in FIG. 7), and the other end in the longitudinal direction of the main body portion 41 is provided. On the short side (left side in Fig. 7), a fixing portion 41b to which the nozzle head 42 is fixed is provided.

The nozzle head 42 has a diameter larger than that of the main body portion 41, and a fluid introduction chamber 42a is provided therein, and the fluid introduction chamber 42a has an inner portion and a main body portion of the rotary joint 27 ( Seawater W (see Fig. 8) flowing through the inside of the tank 41 is introduced. The seawater W introduced into the fluid introduction chamber 42a is sprayed to the outside through the first opening 43a and the second opening 43b provided in the nozzle head 42. Further, each of the openings 43a and 43b constitutes injection holes of the waterproof nozzle in the present invention.

Each opening 43a, 43b is formed in the rectangular shape extended along the longitudinal direction (left-right direction in figure) of the ship 10 as shown to FIG. 6 (a). In addition, the opening angles of the openings 43a and 43b are set to 120 degrees around the nozzle head 42 as shown in Fig. 6 (b), and the fluid introduction chamber 42a and the openings 43a and 43b are shown. A plurality of radially uneven grooves 44a and 44b are provided between the two beams. Each of the uneven grooves 44a and 44b radially guides the flow of the seawater W from the fluid introduction chamber 42a, thereby allowing the seawater to be sprayed to the outside in the shape of a fan in each of the openings 43a and 43b. (See Fig. 8).

As shown in FIG. 7, the first opening 43a is formed with an inclination angle of 3 ° in the longitudinal direction of the nozzle head 42, and the second opening 43b is in the longitudinal direction of the nozzle head 42. As shown in FIG. It is formed with an inclination angle of 8 °. As a result, the seawater W injected from each of the openings 43a and 43b does not aggregate and disperse as if they cross at the lower side of the bulk waterproof nozzle 40, that is, at the lower part of the freeboard portion of the vessel 10.

Specifically, as shown in Fig. 8, when the seawater W sprayed from each of the openings 43a and 43b (see Figs. 6 and 7) is set to a water quantity of 20 m³ / h and a water pressure of 0.2 MPa, each opening is shown. The seawater W sprayed at (43a, 43b) falls in an approximately fan shape. Then, to form an approximately rectangular shape of 1.0 m to 2.0 m in the longitudinal direction of the vessel 10 and the width direction of the vessel 10 at a lower portion of 8.0 m corresponding to the height of the freeboard portion of the vessel 10. It is. That is, by making the shape of the seawater W into a substantially rectangular shape of 10.0 m × 1.0 m to 2.0 m, for example, the seawater W can be efficiently collected in a small boat (pirate ship) having a length of 7.0 m.

Thus, by setting the shape and the inclination angle of each of the openings 43a and 43b, and providing the uneven grooves 44a and 44b, as shown in Figs. In the approaching pirate ship portion, the shape of the seawater W is made into a substantially rectangular shape of 10.0 m × 1.0 m to 2.0 m, whereby the pirate can be quickly exposed to the fear of overturning. In addition, since the seawater W injected from each of the openings 43a and 43b has a substantially fan shape as shown in FIG. 8 and covers the circumference of the ship 10 like a curtain, even from a distance as in the case of the Abare hose 30 It is easy to check.

As shown in Figs. 1 and 3, the Avare hose 30 and the bulk waterproof nozzle 40 are alternated at intervals of 5.0 m through each I-shaped pipe 20 and each T-shaped pipe 21. Plural number is installed. That is, a large quantity of waterproof nozzles 40 are provided between the neighboring hose members 32. The spacing of each of the neighboring hose members 32 and the spacing of each of the adjacent bulk waterproof nozzles 40 are 10.0 m, respectively, whereby the Avare hose oscillates in the front, rear, left, and right directions as shown in FIG. (30) does not become entangled with each other. In addition, it is possible to continuously cover the starboard portion, the port portion and the stern portion of the vessel 10 with a curtain formed by the seawater W from each of the bulk waterproof nozzles 40 in the figure.

Hereinafter, the operation of the pirate intrusion prevention apparatus 18a formed as described above will be described in detail with reference to the drawings.

First, the seawater discharge valve 17a shown in Fig. 3 is opened by the operator. The seawater W is then pumped from the seawater pump to the I-shaped pipe 20 and the T-shaped pipe 21 via the seawater discharge valve 17a. Here, the pirate intrusion prevention apparatus 18a is designed to be fully operable by the quantity of water and the water pressure by the opening operation of the seawater discharge valve 17a.

 The seawater W pumped to the I-shaped pipe 20 and the T-shaped pipe 21 passes through the branch path 21a of the T-shaped pipe 21, as shown by arrow 1 in FIG. While supplied to the hose member 32 of 30, it is supplied to the bulk waterproof nozzle 40 as shown by the arrow (5) of FIG. The seawater W supplied to the hose member 32 reaches the injection hole 33a of the nozzle 33 as shown in Fig. 4, and is then radially sprayed outward from the injection hole 33a.

The seawater W injected from the injection hole 33a generates thrust, whereby the tip side of the hose member 32, that is, the nozzle 33, starts the swinging motion as shown by arrow 2 in FIG. . Here, since the hose member 32 is flexible, it is possible to bend easily in all directions. As a result, the front end side of the hose member 32 swings irregularly with a swing width of 5.0 m in one direction in the front, rear, left and right directions.

With the irregular rocking motion at the tip side of the hose member 32, the weight member 36 is always positioned below the nozzle 33, as shown by arrows 3 and 4 in FIG. Through the connecting rod (35) to be irregularly swinging. Here, since the front end sides of the weight member 36 and the hose member 32 are individually irregularly swinging motion, the weight member 36 at the most front end side of the Avare hose 30 is more complicated and irregularly swinging. Exercise. Such an irregular rocking motion on the tip side of the weight member 36 and the hose member 32, i.e., unpredictable rocking motion on the tip side of the weight member 36 and the hose member 32, becomes a fear to the pirate, This will lower the pirate's motivation.

On the other hand, the seawater W supplied to the bulk waterproof nozzle 40 is sprayed in a substantially fan shape as shown by the arrow (6) of Figure 8, as shown in Figure 1, starboard portion of the vessel 10, A curtain is formed in the port and the stern. At this time, since the seawater W is dispersed in a substantially fan-shaped range (the dot net mesh portion in Fig. 8) without any flow, it is possible to make the thickness of the curtain approximately constant along the periphery of the vessel 10. That is, no gap is formed around the ship 10 to facilitate the intrusion of pirates.

On the contrary, even when the pirate ship approaches the ship 10 side by side, since the bulk waterproof nozzle 40 waterproofs (sprays) the seawater W in large quantities (20 m 3 / h), the pirate ship having a total length of about 7.0 m In this case, the inside of the pirate ship can be submerged to a depth of about 5.0 cm in about 3 minutes. In other words, it is possible to greatly reduce the stability of the pirate ship (breakdown of balance) in about three minutes, and to expose the pirate to fear of overturning with a margin before invading the vessel 10.

As mentioned above, according to the pirate intrusion prevention apparatus 18a which concerns on 1st Embodiment, the base end side is connected to each branch path 21a of each T-shaped piping 21 provided in the upper deck 13, and is distal. The hose member 32 which has a flexible side flanked toward sea surface, the nozzle 33 provided in the front end side of the hose member 32, and the nozzle member provided in the nozzle 33, and spraying seawater W, An injection hole 33a for generating a thrust which swings the tip side of the tip 32, and a weight which is provided in the nozzle 33 and is balanced with the thrust to determine the swing width in the front, rear, left and right directions of the tip side of the hose member 32; The member 36 is provided.

Therefore, in the freeboard portion of the ship 10, it is possible to cause the front end side of the hose member 32 to irregularly swing in the front, rear, left and right directions. The irregular rocking motion of the hose member 32 can be recognized from a distance, and the weight member 36 also becomes a fear to pirates from the irregular rocking motion. As a result, it is possible to lower the pirate's motivation so that the vessel 10 does not approach the ship 10, and furthermore, the ship 10 can be protected from the pirate's wonder. In addition, since the seawater pump or the like already installed on the ship 10 is used as the drive source for oscillating the hose member 32, there is no need to newly install a dedicated drive source, and the existing vessel 10 can be easily and relatively low cost. It is possible to install.

Further, according to the pirate intrusion prevention apparatus 18a according to the first embodiment, one end side is rotatably connected to the nozzle 33 between the nozzle 33 and the weight member 36, and the other end side is the weight member ( Since the connecting rod 35 is rotatably connected to 36, it is possible to make the weight member 36 more complicated and irregularly swing by the irregular rocking motion of the hose member 32.

Further, according to the pirate intrusion prevention apparatus 18a according to the first embodiment, a plurality of hose members 32 are provided at intervals of 10.0 m in each of the pipes 20 and 21 running along the circumference of the upper deck 13, and each Since a large quantity of waterproof nozzles 40 having respective openings 43a and 43b for injecting seawater W toward the surface of the sea between the hose members 32 are installed, the freeboard portion of the vessel 10 can be covered with seawater W curtains. It is possible to prevent the pirates from approaching the ship 10.

In addition, according to the pirate intrusion prevention apparatus 18a which concerns on 1st Embodiment, since each opening part 43a, 43b is formed in the rectangular shape extended along the longitudinal direction of the ship 10, a pirate ship is in contrast to the ship 10 Even when approaching along the lengthwise direction of), it is possible to efficiently collect seawater W on the pirate ship, thereby making it possible to expose the pirate to fear of overturning.

Next, 2nd Embodiment of this invention is described in detail using drawing. In addition, about the part which has the same function as 1st Embodiment mentioned above, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

9 is a partially enlarged view for explaining the detailed structure of the pirate intrusion prevention apparatus according to the second embodiment, and FIG. 10 is an explanatory view for explaining the detailed structure and operation state of the Avare hose 30 according to the second embodiment. Are shown respectively.

As shown in Figs. 9 and 10, according to the pirate intrusion prevention apparatus 50 according to the second embodiment, compared to the first embodiment, the air circuit 60 is added while the Avare hose 70 is attached. The shape of the protection member 71 and the weight member 72 which are formed differs.

The air circuit 60 includes a plurality of air pipes 61, T-shaped pipes 62, and branch pipes 63, and each of the air pipes 61 and the branch pipes 63 is a rubber having flexibility. It is formed by a tube or the like. Here, the air piping 61, the T-shaped piping 62, and the branch piping 63 comprise the fluid piping in this invention.

One end side of the air circuit 60 is connected to the air discharge valve 64, and the other end side of the air circuit 60 is closed by an end cap (not shown). An air compressor (not shown) is connected to an upstream side of the air discharge valve 64. As the air compressor, for example, an air compressor for starting the engine for starting a diesel engine can be used. Therefore, also in the air circuit, it is possible to install easily in the existing ship 10 at comparatively low cost.

One end side of the branch pipe 63 is fitted and fixed to the T-shaped pipe 62, and the other end side of the branch pipe 63 is fitted and fixed to the air inlet connecting portion 65a provided in the rotary joint 65. The other end side of the branch pipe 63 is provided with a pressure gauge 66 and an air pressure regulating valve 67 from the air inlet connecting portion 65a side, and the air regulating valve 67 is an amount of air supplied to the rotary joint 65, It is to adjust air pressure. Here, the adjustment of the air pressure is performed by the operator adjusting the air pressure regulating valve 67 while looking at the pressure gauge 66.

Thus, according to the pirate intrusion prevention apparatus 50 which concerns on 2nd Embodiment, the air is introduce | transduced from the air introduction connection part 65a of the rotary joint 65, and the inside of the hose member 32 of the Avare hose 70 is carried out. A predetermined amount of air (fluid) A is mixed (see FIG. 10) into the seawater W for circulating water. Thereby, it is possible to rock the front end side of the hose member 32 in the front, rear, left and right directions at a lower flow rate than in the first embodiment.

As shown in Fig. 10, on the proximal end of the hose member 32, a protective member 71 is provided to protect the connection portion with the attachment 31 of the hose member 32. As shown in Figs. The protection member 71 is comprised by the coil spring which made the linear steel material the spiral shape, and is able to deform | transform with a spring property corresponding to the swinging motion of the hose member 32. As shown in FIG. As a result, an excessive force is suppressed from being applied to the connection portion of the hose member 32 with the attachment 31. Here, the swing width of the hose member 32 can be adjusted by appropriately adjusting the length of the protective member 71.

The weight member 72 is installed in the nozzle 33 via the connecting rod 35. The weight member 72 is formed into a substantially square shape having a length of 6.0 cm and a weight of 1.0 kg, for example, by cutting a block-shaped steel material. Also in the weight member 72, it is possible to confirm from a distance and may be colored by white, yellow, fluorescent color, etc. in order to see more clearly.

Accordingly, by opening the seawater discharge valve 17a and the air discharge valve 64, as shown by the arrow 7 and the arrow 8 of FIG. 10, the rotary joint portion 65, i.e., an Avare hose Air A is mixed in the seawater W in the upstream portion of 70. Thereafter, the mixed fluid WA of seawater W and air A is injected from the injection hole 33a of the nozzle 33, whereby the front end side of the hose member 32 is shown by the arrow 9 in FIG. I'm rocking.

As mentioned above, also in the pirates intrusion prevention apparatus 50 which concerns on 2nd Embodiment, it is possible to achieve the same effect as 1st Embodiment mentioned above. In addition, in the second embodiment, the air A is mixed in the seawater W supplied to the abare hose 70. It is possible to oscillate the Avare hose 70 with less seawater W, and furthermore, it is possible to easily install a pirate intrusion prevention device at a low cost in a small vessel 10 in which a small seawater pump or the like is installed. .

This invention is not limited to each said embodiment, Needless to say that various deformation | transformation is possible within the range which does not deviate from the summary. For example, in each of the embodiments described above, the pirate intrusion prevention apparatuses 18a and 50 are provided with both the Avares hoses 30 and 70 and the bulk waterproof nozzle 40. However, the present invention is not limited thereto. In addition, since the Avares hoses 30 and 70 give the pirates sufficient fear, the bulk waterproof nozzle 40 may be omitted.

In each of the above embodiments, seawater W is supplied to the Avare hoses 30 and 70, and the front end side of the hose member 32 is irregularly swayed in the front, rear, left and right directions. Not limited to this, it is also possible to irregularly swing the front end side of the hose member 32 in the front, rear, left and right directions by supplying only air to the Avare hoses 30 and 70 and controlling the supply amount of air.

In addition, in each said embodiment, although the weight members 36 and 72 were formed in circular shape and substantially square, the present invention is not limited to this, You may form in other shapes, such as a triangle, a pentagon, a spherical shape, and And size can be set freely. The yaw may be of a shape and size such that the irregular rocking motion of the weight member 36 gives the pirate fear and further reduces the pirate's motivation.
