Description

Ship side impact resistant shock absorbing device

Technical Field

The invention belongs to the technical field of ship protection, and in particular relates to a ship side anti-impact shock absorbing device.

Background technique

Since ships float on the water, they cannot be as stable as on land. Therefore, ships are prone to collisions when docking, entering ports, or when multiple ships are traveling in close proximity. This is especially true when moored at the shore. Therefore, the outside of the ship needs to be buffered and protected from collisions to reduce damage to the hull caused by collisions.

At present, a common anti-collision measure for ships is to place a plurality of waste rubber tires on the side wall of the ship, and use the buffering force of the rubber tires to achieve the anti-impact and shock-absorbing effect of the ship. There are also devices that protect the side of the ship through a specific buffering and shock-absorbing structure, such as a ship side anti-impact and shock-absorbing device and a ship disclosed in patent publication number CN114475954A;

However, the conventional method of protecting the side of the ship with rubber tires cannot fully cover the side of the ship. It is usually only installed in a position prone to collision, and the protection area is relatively limited. Although the impact-resistant shock-absorbing device disclosed in the above patent can be installed on the side of the ship for a relatively comprehensive coverage, it will increase the resistance of the ship's travel and excessively increase the travel burden. At the same time, conventional rubber tires also have this problem and the use effect is not good.

During normal driving, the flexible rubber pads can be quickly and conveniently folded up to minimize the resistance during driving and reduce the driving burden.

2. By setting up the water injection component, water can be injected into the flexible rubber pad when the ship is protected against impact. The injected water makes the flexible rubber pad expand, so that the filled water can be used to absorb the impact potential energy, improve the unloading effect of the impact force, and have a good anti-impact and shock-absorbing effect.

3. By setting up the anti-wave buffer component, when large waves appear, the unfolded flexible rubber pad can be used to buffer and protect the waves, reduce the impact of the waves on the ship, and improve the stability of the ship in the waves.

4. Through the cleaning component, the barnacles adsorbed on the side of the ship can be removed as much as possible during the unfolding of the flexible rubber pad. In conjunction with the backwash component, the high-pressure pump of the water injection component can be used to flush the lower side of the ship during the recovery of the flexible rubber pad, thereby removing some barnacles with weak adsorption. Through the mutual cooperation of the sodium chloride storage hopper, pressure relief pipe and pressure relief valve, sodium chloride can be added and the salt water can be sprayed out by pressure relief during buffering, so that the sodium chloride can be used to destroy the shell of the barnacle and affect the physiological function of the barnacle, thereby playing a role in assisting the removal of barnacles and effectively reducing the impact of barnacles on ships.

Under the action of the extension part 20 and the action of the non-magnetic plate 131, since the upper side of the extension part 20 has a certain extension space, it can be ensured that the flexible rubber pad 8 can be converted from a vertical shape to an inclined shape after being subjected to the pressure of the non-magnetic plate 131.

Two fixed plates 9 are fixedly installed on the outer side wall of the head of the ship body 1, and a second winding mechanism 10 electrically connected to the controller 3 is provided between the two fixed plates 9. The second winding mechanism 10 winds and reels multiple steel ropes 11, and the movable ends of each steel rope 11 are fixedly connected to the movable plate 5. A guide roller 22 is rotatably provided between the two fixed plates 9, and each steel rope 11 is connected to the movable plate 5 through the guide roller 22. Under the action of the guide roller 22, the steel rope 11 can be directed to move along the side of the ship body 1 to ensure the smooth deployment of the flexible rubber pad 8.

The interiors of the flexible rubber pad 8 and the movable plate 5 are both hollow, and the flexible rubber pad 8 is connected to the movable plate 5. A water injection assembly 12 connected to the flexible rubber pad 8 is installed at the bottom of the movable plate 5. The water injection assembly 12 includes a support frame 121 fixedly installed at the bottom of the movable plate 5. A high-pressure pump 122 is fixedly installed on the end surface of the support frame 121. A water suction pipe 123 is fixedly installed at the suction end of the high-pressure pump 122, and the pipe end of the water suction pipe 123 passes through the bottom of the support frame 121. A water delivery pipe 124 is fixedly installed at the output end of the high-pressure pump 122, and the pipe end of the water delivery pipe 124 is fixedly connected to a connecting hose 125. The connecting hose 125 is connected to the hollow plate, and a filter (not shown in the figure) is installed at one end of the water suction pipe 123 to prevent foreign matter with too large a particle size from being sucked in.

A plurality of wave-proof buffer components 13 are installed on the side wall of the ship body 1, and each wave-proof buffer component 13 includes a non-magnetic plate 131 hinged to the side wall of the ship body 1. A mounting groove 132 is opened on the side wall of the ship body 1, and a third winding mechanism 133 electrically connected to the controller 3 is installed inside the mounting groove 132. The third winding mechanism 133 winds and reels a sling 134, and the movable end of the sling 134 is fixedly connected to the upper end of the side wall of the non-magnetic plate 131.

A permanent magnet 137 is fixedly plugged into the side wall of the non-magnetic plate 131. After the electromagnetic plate 136 is energized, the magnetic poles of the electromagnetic plate 136 and the permanent magnet 137 facing each other are of the same polarity. Under the effect of like-pole repulsion, the electromagnetic plate 136 will generate a repulsive force on the permanent magnet 137.

A cleaning assembly 14 is installed on the side wall of the water injection assembly 12. The cleaning assembly 14 includes a movable plate 141 fixedly installed at the bottom of the support frame 121, and a scraper 142 set obliquely is fixedly installed on the side wall of the movable plate 141. The scraper 142 and the movable plate 141 are detachably connected, and the scraper 142 can be replaced regularly. The gap between the scraper 142 and the outer wall of the ship body 1 is maintained in the range of 3 cm to 6 cm.

The cleaning component 14 and the water injection component 12 are commonly connected to a backflush component 15, and the backflush component 15 includes a shunt pipe 151 fixedly inserted into the wall of the water supply pipe 124, and a normally closed solenoid valve 152 electrically connected to the controller 3 is installed inside the shunt pipe 151. A normally open solenoid valve 153 electrically connected to the controller 3 is installed inside the water supply pipe 124 at a position above the shunt pipe 151. The interior of the movable plate 141 is hollow, and the shunt pipe 151 is connected to the movable plate 141. A plurality of inclined water spray micropores 154 are provided on the side wall of the movable plate 141. The normally closed solenoid valve 152 and the normally open solenoid valve 153 are connected in series, and the normally closed solenoid valve 152 is energized to open, and the normally open solenoid valve 153 is energized to close.

A sodium chloride storage hopper 16 is fixedly connected to the top of the movable plate 5, and a plurality of pressure relief pipes 17 are fixedly connected to the bottom of the flexible rubber pad 8, and a pressure relief valve 18 is installed inside each pressure relief pipe 17. When the pressure relief valve 18 is subjected to excessive external pressure, its valve plate will be opened, and after the pressure is restored, its valve plate will rebound and reset under the action of its own elastic member.

An oriented roller 21 is rotatably provided between the two support plates 6, and the movable end of the flexible rubber pad 8 passes through the two oriented rollers 21. Under the action of the two oriented rollers 21, the flexible rubber pad 8 can be spread out parallel to the ship body 1, and when the flexible rubber pad 8 is rewound, the remaining water inside the flexible rubber pad 8 can be discharged through the pressure relief pipe 17 under the squeezing action of the oriented rollers 21.

The operating principle of the present invention is now described as follows: when the ship body 1 needs to dock or travel in complex waters such as when there are many ships around, the personnel starts the controller 3, and the controller 3 controls the first winding mechanism 7 to unwind and controls the second winding mechanism 10 to rewind. The second winding mechanism 10 can synchronously drag the movable plate 5 to move stably along the two guide rails 4 by rewinding a plurality of steel ropes 11. At this time, the flexible rubber pad 8 is unfolded at a uniform speed. After the first winding mechanism 7 and the second winding mechanism 10 work for a certain period of time, the working time is set by the controller 3 according to the length of the ship body 1 and stops working. At this time, the movable plate 5 moves from the stern of the ship body 1 to the head, so that a relatively comprehensive coverage can be performed on one side of the ship body 1 from the bow to the stern;

When the controller 3 starts the first winding mechanism 7 and the second winding mechanism 10, the controller 3 will also start the high-pressure pump 122 synchronously. The high-pressure pump 122 can draw seawater through the suction pipe 123, and transport it to the connecting hose 125 through the water delivery pipe 124, and then enter the flexible rubber pad 8 through the connecting hose 125 and the movable plate 5. As the flexible rubber pad 8 unfolds, the entering water will cause the flexible rubber pad 8 to swell. The controller 3 controls the high-pressure pump 122 to work for a certain time. The working time is set by the controller 3 according to the length of the flexible rubber pad 8 and then stops working. At this time, if the ship body 1 collides with the shore or other ships, the flexible rubber pad 8 will be swelled by the flexible rubber pad 8. The cushioning performance of the pad 8 itself and the seawater inside the flexible rubber pad 8 can absorb the impact energy generated by the collision, so as to provide impact resistance and shock absorption for the side of the ship body 1. When the ship body 1 is hit, the flexible rubber pad 8 will be squeezed. At this time, under the action of the squeezing force, the water inside the flexible rubber pad 8 will open each pressure relief valve 18 and discharge the seawater through each pressure relief pipe 17 (wherein, when the ship body 1 is docked or hit, the first impact force is usually large. Therefore, in the first impact, the water inside the flexible rubber pad 8 is mainly used to buffer the first large impact force and minimize the impact of the first large impact force on the ship body 1);

If the ship body 1 encounters larger waves, the personnel can also start the controller 3, and the controller 3 controls the first winding mechanism 7 and the second winding mechanism 10 to unfold the flexible rubber pad 8. After the flexible rubber pad 8 is unfolded, the controller 3 will control the third winding mechanism 133 and the electromagnetic plate 136 to work regularly. At this time, the third winding mechanism 133 can release each sling 134. Under the action of gravity, each non-magnetic plate 131 will rotate around the hinge point with the ship body 1. After the non-magnetic plate 131 contacts the flexible rubber pad 8, under the action of gravity of the non-magnetic plate 131, the upper side of the flexible rubber pad 8 will be subjected to pressure. At this time, the extension part 20 of the flexible rubber pad 8 will be unfolded, so that the flexible rubber pad 8 can be rotated from the vertical direction to the horizontal direction. The straight shape is changed into an inclined shape. When the sea waves hit the ship body 1, the sea waves will first contact the flexible rubber pad 8. After the flexible rubber pad 8 is impacted by the sea waves, it will drive each non-magnetic plate 131 to rotate. In this process, the flexible rubber pad 8 and the non-magnetic plate 131 can consume part of the impact force of the sea waves. When the non-magnetic plate 131 rotates, since the electromagnetic plate 136 is energized, the magnetic poles of the electromagnetic plate 136 and the permanent magnet 137 facing each other are of the same polarity. Under the effect of like-pole repulsion, the electromagnetic plate 136 will generate a repulsive force on the permanent magnet 137. Therefore, when the non-magnetic plate 131 rotates, the magnetic thrust applied by the electromagnetic plate 136 can further consume the impact force of seawater, thereby effectively reducing the impact of seawater impact on the ship body 1;

When the controller 3 controls the first winding mechanism 7 and the second winding mechanism 10 to unfold the flexible rubber pad 8, the movable plate 5 will drive the movable plate 141 to move synchronously, thereby driving the scraper 142 to move synchronously. During the movement of the scraper 142, if the scraper 142 encounters barnacles adsorbed on the lower side of the ship body 1, the scraper 142 can scrape off the barnacles under the action of the scraper 142 and the steel rope 11, thereby removing some barnacles. At the same time, when the high-pressure pump 122 starts to work, the personnel pours an appropriate amount of sodium chloride into the sodium chloride storage bucket 16, and the sodium chloride enters the movable plate 5 through the sodium chloride storage bucket 16, and enters the flexible rubber pad 8 together with the water entering. Therefore, when the water inside the flexible rubber pad 8 is squeezed and discharged, the water containing high concentration of sodium chloride will be discharged into the waters around the ship body 1 through the pressure relief pipe 17. At this time, since sodium chloride can destroy the shell of the barnacle to a certain extent and affect the physiological function of the barnacle, it can assist in removing some barnacles with poor adaptability.

After the protection of the ship body 1 is completed, the personnel control the first winding mechanism 7 to perform the winding work and the second winding mechanism 10 to perform the unwinding work through the controller 3. At this time, the flexible rubber pad 8 will be gradually retracted. When the flexible rubber pad 8 is recovered, the controller 3 will control the high-pressure pump 122 to work again, and at the same time control the normally closed solenoid valve 152 and the normally open solenoid valve 153 to work at the same time. At this time, the water sucked by the high-pressure pump 122 will enter the shunt pipe 151 through the water pipe 124, and enter the movable plate 141 through the shunt pipe 151. Finally, the water is rapidly sprayed out through each water spraying micropore 154 on the movable plate 141. Under the action of the sprayed water, some barnacles with poor adsorption capacity will also be removed, thereby greatly reducing the number of barnacles adsorbed on the ship body 1 and reducing the impact of barnacles on the ship body 1. After the flexible rubber pad 8 is recovered in place, the controller 3 controls the high-pressure pump 122, the first winding mechanism 7 and the second winding mechanism 10 to stop working;

There are two protective mechanisms 2, which are respectively arranged on both sides of the ship body 1 to protect both sides of the ship body 1. Personnel can protect the side of the ship body 1 that needs to be protected according to needs.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
