Description

Technical Field

[0001] The invention relates to a ship berthing technology, in particular to a ship side-stopping positioning device to prevent running aground and grounding, and belongs to the technical field of ship manufacturing. Background Art

[0002] With the development of automation, the docking of ships on pontoons increasingly requires automatic fixing devices to replace manual fixing of cables on mooring piles. The emergence of the present invention conforms to the development and needs of automation and modernization and is the development direction of ship docking in the future.

[0003] Nowadays, ships are docked and fixed by sailors who put ropes on the mooring piles on the deck of the pontoon and the mooring piles on the deck of the ship. When the ship is not at the dock, the sailors basically have no other work; when there is no ship docking or leaving the port on the pontoon, the sailors on the pontoon have no other work, which leads to a great waste of human resources and increases the operating costs of the dock and the ship. In addition, when the ship is docked, since it cannot be fully positioned, the side of the bow of the ship first contacts the side of the pontoon and collides and rubs, and sparks often appear during the collision and friction. There are great safety hazards.

[0004] On the other hand, when some small ships are in use, they often temporarily stop in some unfamiliar sailing environments to conduct certain surveys or play, but stopping at an unfamiliar river or seaside may be dangerous. The riverbed may rise steeply in the riverside area, and the ship may run aground or collide when docking near the shore, causing danger. There may be a large number of reefs in the seaside area, causing the hull to collide with the reefs, or drive onto the reefs and other hard objects and be stranded on them, losing the freedom of movement and retreat, and it may be difficult to escape from danger in a short time.

[0005] For example, a ship berthing device with application number 201620951674.4 includes a ship body, a fixed frame, a turntable, a distance and direction adjustment system, the fixed frame is fixed on the ship body, the fixed frame includes a driving wheel, the turntable is located above the fixed frame, and the turntable includes a transmission wheel; the distance and direction adjustment system includes a main arm, a sub-arm, a grabbing clamp and a hydraulic control system, the grabbing clamp includes a left clamp and a right clamp connected by a hinge, one end of the main arm is fixed on the turntable, and the other end is hinged to the sub-arm, the other end of the sub-arm is fixedly connected to one end of the non-arc jaw of the right clamp, and one end of the non-arc jaw of the left clamp is fixedly connected to the hydraulic system; the hydraulic system includes a hydraulic cylinder I for controlling the movement direction of the main arm, a hydraulic cylinder II for controlling the movement direction of the sub-arm, and a hydraulic cylinder III for controlling the movement direction of the left clamp of the grabbing clamp; the technical solution is relatively expensive, and during use, it will cause the hull to tilt due to force on one side, and there is a risk of capsizing. Summary of the invention

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below through specific embodiments.

[0019] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by terms such as “vertical”, “up”, “down” and “horizontal” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] like Figure 1 — Figure 3 As shown, a ship of the present invention can be used as a device for preventing a ship from running aground or grounding, and can also be used as a positioning device for side parking. The former is to prevent the ship from being damaged and in a dangerous state, and the latter is to prevent the ship from constantly colliding with the dock or the shore under the impact of waves when docking. The device structure includes a fixed railing 1 and a movable railing 2 installed on the side of the ship. The movable railing 2 moves relative to the fixed railing 1, and the fixed railing 1 and the movable railing 2 are parallel to each other.

[0021] The fixed railing 1 is provided with a strip groove 3 along the length direction. The strip groove 3 is located near one end of the fixed railing 1. A slider 4 is built into the strip groove 3 and moves along the strip groove 3. A spring 5 is provided between the slider 4 and the inner end of the strip groove 3. The slider 4 compresses the spring 5 and moves toward one end of the fixed railing 1.

[0022] The movable rail 2 is provided with a slide rail 6, and the slide rail 6 is provided with a slide seat 7, and the slide seat 7 moves along the slide rail 6;

[0023] The strip groove 3 and the slide rail 6 are located at the same side end position of the fixed railing 1 and the movable railing 2, and the slide block 4 and the slide seat 7 can move synchronously;

[0024] A first folding rod 8 and a second folding rod 9 are provided between the fixed railing 1 and the movable railing 2. One end of the first folding rod 8 is hinged to the slider 4, and the other end is hinged to the end of the movable railing 2 away from the slide rail 6. One end of the second folding rod 9 is hinged to the slide seat 7, and the other end is hinged to the end of the fixed railing 1 away from the strip groove 3.

[0025] The second folding rod 9 is hinged to the end of the fixed railing 1 and has an extension rod, on which an arc-shaped bar 10 is arranged, and the convex surface of the arc-shaped bar 10 has a rack. There is a motor in the ship, and the power output end of the motor has a gear meshing with the rack. The motor can rotate forward and reversely. The motor is a power source, and the rotation drives the rack through the gear to push the first folding rod 8 to support outward. At the same time, the second folding rod 9 also moves relatively, and the slide seat 7 and the slider 4 move the compression spring 5. The fixed railing 1 is fixed to the hull and does not move. The movable railing 2 moves outward and creates a distance between it and the fixed railing 1. When docking at the dock or the artificial river bank, it will keep a certain distance from the hull, so that if a collision occurs during the docking process, the hull will not be damaged, and the movable railing 2 provides a certain buffer for the hull.

[0026] The outer side of the movable railing 2 is provided with a flexible stop bar 11 for mitigating impact force;

[0027] When in an unfamiliar sailing environment and the bottom condition of the riverbed near the shore is unknown, a curved baffle 12 can be set at the bottom of the movable railing 2. The shape of the curved baffle 12 matches the shape of the side of the ship. When the movable railing 2 moves outward, the curved baffle 12 will also move outward. Then, when the ship is docking, the curved baffle 12 can protect the lower part of the hull, avoid a large number of reefs or other hard objects in the waters near the shore, and avoid running aground or impact damage to the bottom of the hull during docking.

[0028] After the ship is docked, it is not enough to be towed by rope only. In the environment of water waves or strong winds, the hull will constantly collide with the dock, which will cause damage in the long run. The high frequency of hull shaking will also affect the people in the ship. Therefore, a positioning mechanism is set between the flexible bar 11 and the movable railing 2. The positioning mechanism includes a rotating wheel 13, a first gear 14, and a second gear 15 installed on the movable railing 2. The rotating wheel 13 is located at one end of the movable railing 2, and the first gear 14 and the second gear 15 are located at the other end of the movable railing 2. Gears are arranged around the outer circumference of the first gear 14 and the second gear 15, and the first gear 14 and the second gear 15 are meshed with each other. A first oar 16 is installed on the rotating wheel 13, and a second oar 17 is installed on the second gear 15. Pulleys are arranged on the rotating wheel 13 and the first gear 14, and a belt 18 is wound between the pulley of the rotating wheel 13 and the pulley of the first gear 14.

[0029] Furthermore, the first paddle 16 and the second paddle 17 move synchronously relative to each other, and the first paddle 16 and the second paddle 17 can be staggered and overlapped, thereby saving space.

[0030] When the boat stops at the shore, the motor drives the rotating wheel 13 to rotate, and the belt 18 drives the first gear 14 to rotate synchronously, and the first gear 14 drives the second gear 15 to rotate in the opposite direction through the gear, so that the first and second oars 16 and 17 are inserted into the mud at the bottom of the riverbed at the shore for fixing. When there is wind and waves, the boat body will not move easily, and the rotating wheel 13 can reverse to retract the first and second oars 16 and 17 to release the fixation;

[0031] Side stop positioning devices are provided on both sides of the ship, and at least one side of the ship is provided with a side stop positioning device.

[0032] The positioning mechanism cooperates with the movable railing 2 and the arc-shaped baffle 12 to allow the driver to move around in unfamiliar waters with confidence, thereby greatly improving the safety of the ship.

[0033] The above is only a preferred specific implementation manner of the present invention, and the protection scope of the present invention is not limited thereto. Any simple change or equivalent replacement of the technical solution that can be obviously obtained by any technician familiar with the technical field within the technical scope disclosed in the present invention falls within the protection scope of the present invention.
