Description

The invention relates to the field of shipbuilding and for the design of bulwarks of ships.

Known bulwark of the vessel, containing the outer wall with a cradle, mounted with buttresses on the deck stringer flooring of the upper deck of the vessel (V. A. Lesyukov. "Theory and arrangement of inland navigation vessels", M .: "Transport", 1982, S. 160 , Fig. 66).

The disadvantage of this vessel bulwark is that it does not protect the vessel from unauthorized entry of people, which can lead to the seizure of the vessel by pirates.

Known engineering protective system "anti-pirate" for the protection of ships, consisting of at least one section with a protective element made in the form of a spirally twisted barbed tape with vertical support nodes installed at a certain interval from each other, while the spiral coils are attached to support nodes, which allows you to create a resistant barrier, and each support node is made in the form of a predominantly vertical rack, consisting of a lower fixed part, fixed on the deck of the vessel, and the upper movably the first part with a latch for its movement, on top of which a roll-up device for winding barbed tape is mounted, made mainly in the form of a winch, mainly with a manual drive, while the winch has several winding drums with locking mechanisms (RF Patent for the invention No. 2431582, IPC B63G 13 / 00, published on October 20, 2011).

The disadvantage of this engineering-protective system is that in the process of erecting a security barrier, the crew is at the side of the vessel and is vulnerable to pirates, who usually have firearms. This circumstance does not allow to erect a protective barrier without threatening the life and health of the crew members of the vessel.

A bulwark mounted on the ship’s hull with the possibility of turning to the side of the ship and fixing in a predetermined position, made of separate sections, including the outer wall and buttresses pivotally mounted on the deck, is adopted as the closest analogue, each buttress is mechanically connected to the driven gear associated with an engine installed below the deck for turning and fixing the buttress in a vertical position overboard (RF Patent for invention No. 2595094, IPC B63B 17/00, B63B 17/04, publ. 08.20.2016).

A significant drawback of this design is that when the bulwark sections are turned from deck to side, only insignificant obstacles are created for unauthorized persons to enter the ship, which makes it impossible to safely operate the ship in areas of the oceans where pirates operate.

The invention solves the problem of improving the safety of navigation, reducing the likelihood of a ship being captured by pirates by creating a barrier to prevent unauthorized persons from entering the ship.

To obtain the desired technical result, a bulwark mounted on the ship’s hull with the possibility of turning to the side of the ship and fixing in a predetermined position, made of separate sections, including the outer wall and the buttresses pivotally mounted on the deck, is proposed to be equipped with protective sections pivotally mounted on the ship’s deck with possibility of rotation in the direction from the deck to the side.

In the proposed technical solution, in case of danger of an attack by pirates, the bulwark sections are rotated in the direction from the deck to the side, while the protective sections rotate in the same direction and are installed obliquely to the vertical, relying on the bulwark sections, as a result of which access to the ship is difficult persons and decreases the likelihood of a ship being captured by pirates.

The accompanying drawings show: in FIG. 1 is a top view of a bulwark in the normal operation of the vessel;

in FIG. 2 is a side view of the bulwark section in the normal operation of the vessel;

in FIG. 3 is a side view of the bulwark section in the mode of restricting access to the ship to unauthorized persons.

In the drawings, the following notation:

1 - deck;

2 - bulwark section with a tackle;

3 - buttress;

4 - the outer wall of the bulwark section;

5 - articulated buttress support;

6 - engine;

7 - shaft;

8 - an epiploon;

9 - a leading gear wheel;

17 - a cable.

The construction of the bulwark consists of the bulwark sections with a gun 2, containing the outer wall of the bulwark sections 4 and buttresses 3, pivotally mounted on deck 1 using the articulated supports of buttress 5. In the area of articulation to the deck, buttress 3 is rigidly connected to the driven gear wheel 10, which is included in engagement with the driving gear 6 of the rotary engine 6. The torque from the engine 6 is transmitted through the shaft 7, on which the stuffing box is installed 8. On the inside there is a cladding 13 connected with and knits 14 to deck 1. Between the lining 13 and the outer walls of the bulwark sections 4, protective sections 11 are installed, consisting of racks of the protective section 16 and barbed tape 15. The stands of the protective section 16 are mounted on deck 1 by the hinged supports of the protective section 12 and are connected by cables 17 with buttresses 3.

The bulwark works as follows. In the normal operation of the vessel, the bulwark sections with plank 2 are in the initial position shown in FIG. 1 and FIG. 2. In this case, the protective sections 11 are enclosed between the outer walls of the sections of the bulwark 4 and the lining 13, mounted on deck 1 with the help of knits 14. In this position, the crew is protected from impacts from the barbed tape 15, which are equipped with protective sections 11 and on the deck of the vessel 1 all necessary production operations can be carried out without restrictions. If there is a danger of an attack on a pirate ship, then at the command of the skipper, the bulwark sections with the gun 2 are rotated in the direction from the deck to the board until the upper parts of the bulwark sections with the gun 2 are lowered, as shown in Fig. 3. The sections of the bulwark with the scaffold 2 rotate relative to the hinge supports of the buttresses 5, while the axes of rotation pass through the center of the driven gears 10. Following the sections of the bulwark with the scaffold 2, the protective sections 11 are turned in the same direction, consisting of the struts of the protective sections 16 and the barbed tape 15 and fixed on deck 1 using the hinged supports of the protective section 12. In this case, the length of the cable 17 and the points of its fastening on the stands of the protective sections 16 and buttresses 3 are selected so that when the bulwark sections are located 2 in the lower position, the cable 17 did not allow the protective section 11 to return to its original position even under the action of external forces applied in the direction from the side to the deck. Otherwise, when unauthorized persons attempted to enter the vessel, the protective section 11 could be turned by them in the direction from the side to the deck with overcoming the gravity acting on the protective section 11, which would facilitate unauthorized access to the vessel.

The rotation of the bulwark section with the scaffold 2 is carried out using the engine 6 mounted below deck 1. The engine rotates the shaft 7 on which the driving gear 9 is mounted, as a result of which the bulwark section 2 is rotated and takes a vertical position. In this position, the shaft 7 is fixed, preventing further movement of the bulwark section 2. At the same time, the protective sections 11 are supported by the bulwark sections with a scaffold 2, while being in a position deviated from the vertical towards the water, which greatly complicates the access of unauthorized persons to the vessel. For this, the protective sections 11 are equipped with barbed tape 15, which can also be wound on the posts of the protective section 16 to increase the protection efficiency. In this case, the barbed tape 15 can be mounted on the protective sections both linearly in one or several directions, and in the form of turns. Along with the barbed tape 15 in the protective sections 11 can also be used barbed wire of various configurations, which makes it difficult for unauthorized persons to enter the ship.

It should be noted that, in contrast to the known structures in the proposed technical solution, when transferring the protective sections 11 to the position of restricting access to the vessel by unauthorized persons, crew members are not required to be at the edge of deck 1, which significantly increases their safety, making it impossible for various weapons to side of the pirates.

Thus, the proposed design allows to reduce the likelihood of unauthorized persons, including pirates, entering the ship, thereby increasing the safety of navigation in those areas of the oceans where pirates are active.
