Description

Technical Field

[0001] The invention relates to the technical field of ship refloating, and in particular to equipment for assisting a stranded ship in refloating. Background Art

[0002] A ship grounding refers to a situation where a ship accidentally hits the bottom or gets stuck in shallow water and cannot move freely, which not only causes damage to the ship itself, but may also cause serious environmental problems and economic losses. The reasons for grounding vary, mainly including navigation errors, weather and sea conditions, tidal changes, mechanical failures, and cargo displacement. Navigation errors are the most common cause. Due to crew misoperation, navigation equipment failure, or underestimation of channel conditions, the ship deviates from the scheduled route and enters an area with insufficient water depth; bad weather such as strong winds, big waves, and rapids make it difficult to control the ship and force it to deviate from the safe channel; incorrect calculation of tidal heights or ignoring tidal patterns in specific sea areas may cause the ship to be trapped on shoals or reefs at low tide; sudden failures of the power system, steering gear, or other key mechanical equipment may cause the ship to lose control; if the cargo is not properly fixed during transportation, it will shift during navigation, changing the center of gravity distribution of the ship and increasing the risk of capsizing or grounding.

[0003] When a ship runs aground, it faces a range of potential problems, including physical damage, environmental pollution, economic costs, and ecological impacts. The hull structure may be damaged by hitting the seabed or rocks, resulting in secondary disasters such as water ingress or oil leakage; especially when an oil tanker or chemical tanker runs aground, it may cause fuel or chemical leakage, polluting the marine environment; the additional costs of repairing hull damage, cleaning up pollution, and delaying the journey are huge; groundings may also damage local marine ecosystems, especially sensitive areas such as coral reefs or wetlands.

[0004] Traditional methods of getting a ship out of trouble usually rely on several aspects: tidal utilization, external towing, unloading cargo, dredging and inflatable buoys. Waiting for high tide to provide enough water depth for the ship to float again is simple but subject to time and tidal cycles; using tugboats to pull the stranded ship back to deep water requires accurate assessment of force requirements and avoidance of further damage to the hull; reducing the weight of the ship to reduce the draft depth, making it easier to get out of the bottom obstacles, but this is not always feasible; helping it to restore buoyancy by digging or removing the sand under the ship, this work requires special equipment and technical support; placing large inflatable buoys around the ship to increase additional buoyancy, but the effect is limited for large ships, and it is necessary to consider whether the site conditions allow the installation of buoys. These traditional methods have their own advantages and disadvantages, and in practical applications, it is often necessary to select the most appropriate solution based on the specific situation. However, these methods are usually complex, time-consuming, costly, and sometimes difficult to guarantee successful escape. Therefore, it is of great practical significance to develop an efficient, simple and reliable auxiliary device for rapid response to ship stranding. The present invention aims to provide an innovative technical solution to solve this problem. Summary of the invention

[0035] Embodiment 1:

[0036] Figure 1-Figure 9The present invention shows a device for assisting the stranded ship in getting out of the refloat, including a shell 1 and a pressure rod 3. An inflatable bag 2 is arranged on the shell 1. The inflatable bag 2 includes a connected inner cushion part 21 and a support part, wherein the inner cushion part 21 is fixedly connected to the inner side of the shell 1 to ensure that the entire inflatable bag 2 is connected and fixed to the shell 1 and will not separate from the shell 1. The support part expands and becomes larger after being inflated, exerting a supporting force on the stranded ship 4 to compensate for its buoyancy loss caused by the stranding. Openings are circumferentially arranged on the side of the shell 1 for the support part to extend out. The openings and the inflatable bag 2 are circumferentially arranged so that the support part surrounds the shell 1 after inflation, ensuring that at least one support part can abut against the bottom of the ship 4 to exert a supporting force on it.

[0037] The shell 1 and the pressing rod 3 are arranged in a matching manner. The pressing rod 3 is used to press the shell 1 into the shore where the ship 4 is stranded, so a pressing groove 14 is arranged at the rear end of the shell 1 to cooperate with the end 31 of the pressing rod 3 to facilitate the positioning and clamping of the pressing rod 3 and the shell 1.

[0038] A ventilation duct 11 is arranged inside the shell 1, and an inflation port 12 is arranged at the rear end of the shell 1. The inflation port 12 is connected to the ventilation duct 11. A staff member connects an inflation hose to the inflation port 12, and fills gas into the ventilation duct 11 through the hose by an air pump on the ground. The inner cushion part 21 is connected to the ventilation duct 11, and the injected gas finally enters the support part, causing the support part to expand.

[0039] A flat head is not conducive to pressing the shell 1 into the ground, so the head of the shell 1 is set to a conical head 13 so that it can drill into the soil, making it easier for the entire shell 1 to extend into the ground and approach the bottom of the stranded ship 4.

[0040] The opening is designed to be long and strip-shaped and is arranged along the front and rear directions of the shell 1. Correspondingly, the support portion is also designed to be strip-shaped and includes two front and rear connecting ports, which are respectively connected to the front and rear ends of the inner cushion portion 21 through the two connecting ports. When the airbag 2 is inflated, the support portion expands and bends into an arc shape. The entire airbag 2 is "D"-shaped, and there is a gap between the support portion and the inner cushion portion 21 for mud and water to pass through.

[0041] In this embodiment, six groups of openings and airbags 2 are arranged along the circumferential direction of the side of the shell 1. The number of openings can be changed according to actual conditions, and the number of airbags 2 is the same as the number of openings.

[0042] A turning handle 32 is provided at one end of the pushing rod 3, and the turning handle 32 can be grasped by the staff or connected to an external mechanical device. When the end 31 of the pushing rod 3 is matched and connected with the pushing groove 14 at the rear end of the shell 1, the pushing rod 3 is alternately turned clockwise and counterclockwise by the turning handle 32, and the shell 1 and the pushing rod 3 rotate repeatedly together, and the conical head 13 at the front end of the shell 1 continuously drills the soil, and the entire shell 1 slowly penetrates into the ground close to the bottom of the ship 4.

[0043] The support part is deflated when not inflated. At this time, the support part is scattered and cannot be fixed. The support parts extending from two adjacent openings are easily tangled together. Arranging the support parts in an orderly manner is conducive to subsequent storage and the housing 1 is deeply embedded in the ground. The housing 1 of the present invention is provided with a snap seat 15 on the outer side near the opening, and a snap 23 is provided on the outer side of the support part. The snap 23 cooperates with the snap seat 15 to simply fix the support part on the housing 1 to prevent the support part from scattering. When the support part is inflated and expanded, the snap 23 is pulled to separate it from the snap seat 15. After use, the snap 23 is pressed into the snap seat 15.

[0044] The practical scenario of the present invention is in the soil near water. After use, the outer side of the shell 1 is often attached with mud and sand, and the internal gap of the shell 1 is also easily mixed with mud and sand, which is difficult to clean. Therefore, the conical head 13 is designed to be detachable. Specifically, the conical head 13 can be tightened and fixed to the front end of the shell 1 through threaded matching. A leakage hole 111 is set on the ventilation pipe 11. When the present invention is recycled after use, the conical head 13 is disassembled, and then the leakage hole 111 on the ventilation pipe 11 is opened, and the water pump output port is connected to the inflation hole. Water is filled into the ventilation pipe 11, so that it is sprayed out from the leakage hole 111, and the shell 1 is flushed. After flushing, pour out the excess water. The leakage hole 111 is provided with a thread, and a bolt with a sealing rubber ring is correspondingly provided and tightened and fixed at the leakage hole 111 to ensure that the leakage hole 111 will not leak when the ventilation pipe 11 and the inflatable bag 2 are inflated.

[0045] Usage process:

[0046] First, check the shell 1, the inflatable bag 2, the push rod 3 and other components to ensure that they are intact. After the support part is inflated, the initial inflation test can separate the snap button 23 and the snap button seat 15 by pulling, and then press the end 31 of the push rod 3 into the push groove 14 at the rear end of the shell 1. Select a suitable insertion point on the shore where the ship 4 is stranded, so that the conical head 13 of the shell 1 faces the soil, hold or connect the mechanical equipment to the turning handle 32 of the push rod 3, and twist it alternately to allow the front end of the shell 1 to drill the soil until it goes deep into the ground and approaches the bottom of the ship 4. The hose is pre-connected to the air pump and the inflation port 12 at the rear end of the shell 1. Start the air pump to inflate the ventilation pipe 11. The gas enters the inner cushion part 21 and the support part to expand it to form a "D"-shaped structure, exerting a supporting force on the stranded ship 4 to help it get out of the stranded position. During this period, the state of the ship 4 and the pressure of the inflatable bag 2 are continuously monitored. When the boat 4 is successfully freed, turn off the air pump, release the gas from the inflation port 12, and wait for the support part to deflate. Recover the shell 1 by pulling the hose, then remove the conical head 13, open the drain hole 111 on the ventilation pipe 11, connect the water pump outlet to flush the shell 1 and its internal gaps with water to remove mud and sand, pour out the excess water and reassemble the conical head 13, organize and store all the parts for next use.

[0047] Embodiment 2:

[0048] Figure 1-Figure 9 The present invention shows an auxiliary device for refloating a stranded ship. The difference between this embodiment and embodiment 1 is that the structure of the top pressure groove 14 is optimized in this embodiment. Specifically, the top pressure groove 14 is arc-shaped, and an inner groove 141 is provided on the side of the top pressure groove 14. A notch 142 is provided at the end of the inner groove 141 away from the shell 1. The end 31 of the top pressure rod 3 is provided with a hook 33, and the hook 33 cooperates with the inner groove 141. When the top pressure rod 3 cooperates with the top pressure groove 14, the hook 33 is first aligned with the notch 142, and then the end 31 is pressed into the top pressure groove 14 to complete the connection and cooperation between the top pressure rod 3 and the shell 1.

[0049] When the pressing rod 3 presses the shell 1 into the ground, the force direction is opposite to the direction of the notch 142, and the end 31 of the pressing rod 3 is not easy to separate from the pressing groove 14. When the stranded ship 4 is rescued and needs to be recovered, the pressing rod 3 is twisted to make the hook 33 misaligned with the notch 142 and inserted into the inner groove 141, and then the pressing rod 3 is pulled, and the pressing rod 3 drives the entire shell 1 to slowly move toward the ground until it is out of the ground, completing the recovery operation.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
