Description

Technical Field

[0001] This invention relates to the field of ship dismantling technology, and in particular to a multifunctional and environmentally friendly ship dismantling dock. Background Technology

[0002] In recent years, with the increasing global awareness of environmental protection and the deepening of the concept of green development, ship dismantling has become a production activity that reduces the pollution caused by abandoned ships and turns waste into treasure for resource recycling. With increasingly stringent environmental regulations and continuous technological progress, exploring green ship dismantling technologies to achieve environmentally friendly and efficient ship dismantling has become an important direction for the development of the ship dismantling industry.

[0003] However, traditional pollution control methods used in ship dismantling, such as relying on oil booms to intercept oil spills or using absorbent pads to absorb leaks, are prone to failure under complex sea conditions or operational errors, increasing the risk of oil spills. Furthermore, traditional flame cutting methods suffer from low cutting precision, high material waste, and widespread dust and diffusion of hazardous substances. The cutting process also requires manual operation, resulting in low efficiency, significantly increased occupational exposure risks, and substantial losses of human and material resources.

[0004] In summary, the existing ship dismantling process suffers from problems such as high pollution, high operational risks, low resource utilization, and low dismantling accuracy. Summary of the Invention

[0005] In view of this, it is necessary to provide a multi-functional and environmentally friendly shipbreaking dock to solve the problems of high pollution, high operational risks, low resource utilization and low dismantling accuracy in the existing ship dismantling process.

[0006] This invention provides a multifunctional and environmentally friendly shipbreaking dock, comprising a dock body, a dock gate, a three-axis moving platform, a high-pressure water jet cutting assembly, and a negative pressure suction assembly. The dock body is hollow inside and has openings on its side walls. The dock gate is movably connected to the openings of the dock body for opening and closing. The three-axis moving platform is installed inside the dock body and has a movable end that can move in any direction. The high-pressure water jet cutting assembly is connected to the movable end of the three-axis moving platform and has a high-pressure water jet cutting end. The negative pressure suction assembly has a recovery end connected to the bottom of the dock body for recovering waste liquid.

[0007] Furthermore, the inner bottom wall of the dock body is recessed downward to form a dismantling pool, the dismantling pool is connected to the opening of the dock body, the three-axis moving platform straddles the dismantling pool, and the recovery end of the negative pressure suction component is connected to the dismantling pool.

[0008] Furthermore, the dock gate is a roller shutter door located on the top of the opening side of the main body of the dock. The sides and bottom of the roller shutter door can be fitted into the sealing grooves opened on the dock gate. An airbag is provided in the sealing groove. When inflated, the airbag can seal against the sides and bottom of the roller shutter door.

[0009] Furthermore, the three-axis moving platform includes an X-axis moving component, a Y-axis moving component, and a Z-axis moving component. The X-axis moving component is installed inside the dock body and has a moving end connected to the Y-axis moving component, used to drive the Y-axis moving component to move along an opening direction close to or away from the dock body. The moving end of the Y-axis moving component is connected to the Z-axis moving component, used to drive the Z-axis moving component to move horizontally along a direction perpendicular to the Y-axis moving component. The moving end of the Z-axis moving component is connected to the high-pressure water jet cutting assembly, used to drive the high-pressure water jet cutting assembly to move vertically.

[0010] Furthermore, the high-pressure water jet cutting assembly includes a nozzle, which is connected to the output end of the three-axis moving platform. One end of the nozzle is a nozzle, and the other end of the nozzle is an inlet for connecting external high-pressure water.

[0011] Furthermore, the high-pressure water jet cutting assembly also includes a robotic arm, which is connected to the output end of the three-axis moving platform, and the gripping end of the robotic arm is connected to the nozzle.

[0012] Furthermore, the high-pressure water jet cutting assembly also includes a booster, a feeder, and a water pump. The booster has a booster chamber, and an inlet, an abrasive inlet, and an outlet connected to the booster chamber. The outlet end of the feeder is connected to the abrasive inlet of the booster. The water pump is connected to the inlet of the booster, and the outlet of the booster is connected to the inlet of the nozzle.

[0013] Furthermore, the negative pressure suction assembly includes a storage container, a suction pump, and a connecting pipe. The water inlet of the suction pump is connected to the bottom of the dock body via the connecting pipe, and the water outlet of the suction pump is connected to the storage container.

[0014] Furthermore, it also includes a crane installed on the three-axis moving platform, the three-axis moving platform being used to drive the crane to move in the horizontal direction.

[0015] Furthermore, it also includes a photovoltaic power generation module installed on the top of the main body of the dock.

[0016] Compared with existing technologies, this method involves docking the ship to be dismantled inside the main dock, closing the dock's opening through a gate to create a fully enclosed structure. A three-axis moving platform then moves a high-pressure water jet cutting assembly along a pre-designed trajectory to cut and clean the ship, achieving precise dismantling. Throughout the dismantling process, the ship remains within the fully enclosed structure, controlling dust diffusion and oil leakage at the source and preventing harmful substances such as asbestos from spilling into the atmosphere. Simultaneously, a negative pressure suction assembly can recover wastewater, waste oil, and waste residue generated during the cutting and cleaning operations, improving resource utilization.

Detailed Implementation

[0018] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1-2As shown, the present invention provides a multifunctional environmentally friendly shipbreaking dock, comprising a dock body 100, a dock gate 200, a three-axis moving platform 300, a high-pressure water jet cutting assembly 400, and a negative pressure suction assembly 500; the dock body 100 is hollow inside and has openings on its side walls; the dock gate 200 is movably connected to the opening of the dock body 100 for opening and closing the opening of the dock body 100; the three-axis moving platform 300 is installed inside the dock body 100 and has a moving end that can move in any direction; the high-pressure water jet cutting assembly 400 is connected to the moving end of the three-axis moving platform 300 and has a high-pressure water jet cutting end; the negative pressure suction assembly 500 has a recovery end connected to the bottom of the dock body 100 for recovering waste liquid.

[0020] During implementation, the vessel M to be dismantled is moored inside the main dock 100. The opening of the main dock 100 is closed through the dock gate 200 to form a fully enclosed structure. The three-axis moving platform 300 moves the high-pressure water jet cutting component 400 along a pre-designed trajectory to cut and clean the vessel, thereby achieving precise dismantling of the vessel. Throughout the dismantling process, the vessel is located within the fully enclosed structure, which can control dust diffusion and oil leakage from the source and prevent harmful substances such as asbestos from spilling into the atmosphere. At the same time, the negative pressure suction component 500 can recover wastewater, waste oil, and waste residue generated during the cutting and cleaning operations, improving resource utilization.

[0021] In this implementation plan, the main dock 100 is constructed in the water (usually located on the shore), which can guide the vessel M to be dismantled into the main dock 100 and fix the vessel M to be dismantled using tools such as anchors and ropes.

[0022] In one embodiment, the inner bottom wall of the dock body 100 is recessed to form a dismantling pool 110, which is connected to the opening of the dock body 100. The three-axis moving platform 300 is straddling the dismantling pool 110, and the recovery end of the negative pressure suction component 500 is connected to the dismantling pool 110.

[0023] The inner bottom wall of the main dock 100, located on both sides of the dismantling pool 110, forms a support platform. This platform provides support for the three-axis moving platform 300, ensuring the high-pressure water jet cutting assembly 400 has a certain installation height, and also providing the necessary space for operators and other equipment. Understandably, the length and width of the dismantling pool 110 should be determined according to the dimensions of the vessel M to be dismantled.

[0024] The size of the main dock 100 should be determined according to the size of the ship to be dismantled, and its shape is not limited, but it is preferable to have a stable installation and good resistance to wind and waves.

[0025] Understandably, the aforementioned dismantling pool 110 includes a rough dismantling pool and a fine dismantling pool. The ship first enters the rough dismantling pool of the main dock 100, and water is released into the rough dismantling pool. After the ship is placed on the dock, the terminal issues an instruction to drive the crane 600 and the high-pressure water jet cutting component 400 to the designated cutting position via the three-axis moving platform 300. The cutting range of the high-pressure water jet cutting component 400 can cover the entire working surface of the ship. The dismantled parts are then sent to the fine dismantling pool via the crane 600 for subsequent fine dismantling.

[0026] After the vessel M to be dismantled is introduced into the dock body 100, a closed environment needs to be provided for the vessel to prevent the overflow of wastewater, waste oil, and waste residue generated during the dismantling process, which would affect the ecological environment. Therefore, this implementation plan also includes a dock gate 200, which is movably connected to the opening of the dock body 100 and used to open and close the opening of the dock body 100. The dock gate 200 can be moved to the open state so that the vessel M to be dismantled can be moved into the dock body 100. Of course, the dock gate 200 can also be moved to the closed state, in which case a fully enclosed structure is formed between the dock body 100 and the dock gate 200.

[0027] In one embodiment, the dock gate 200 is a roller shutter door located on the top of the opening side of the dock body 100. The sides and bottom of the roller shutter door can be fitted into a sealing groove opened on the dock gate 200. An airbag is provided in the sealing groove. When inflated, the airbag can seal against the sides and bottom of the roller shutter door.

[0028] In another embodiment, the dock gate 200 may also take the form of a valve. The valve is slidably connected to a slot on the dock body 100 in the vertical direction. The valve can slide downwards to close the opening, and simultaneously slide upwards to open the opening. The valve and the dock body 100 can be sealed with a gasket. The valve can be driven to slide by a power device such as a hydraulic cylinder, and there is no limitation on this.

[0029] Of course, in other preferred embodiments, the dock gate 200 can also be implemented using other structural forms, with the aim of achieving stable connection, convenient opening and closing, and good sealing effect.

[0030] In this embodiment, the three-axis mobile platform 300 is installed inside the dock body 100 and has a mobile end that can move in any direction. The three-axis mobile platform 300 can drive the high-pressure water jet cutting component 400 to carry out precise disassembly of the ship according to a pre-set trajectory.

[0031] like Figure 3As shown, in one embodiment, the three-axis moving platform 300 includes an X-axis moving component 310, a Y-axis moving component 320, and a Z-axis moving component 330. The X-axis moving component 310 is installed inside the dock body 100 and has a moving end connected to the Y-axis moving component 320 for driving the Y-axis moving component 320 to move along the direction of the opening of the dock body 100. The moving end of the Y-axis moving component 320 is connected to the Z-axis moving component 330 for driving the Z-axis moving component 330 to move horizontally along the direction perpendicular to the moving direction of the Y-axis moving component 320. The moving end of the Z-axis moving component 330 is connected to the high-pressure water jet cutting assembly 400 for driving the high-pressure water jet cutting assembly 400 to move vertically.

[0032] like Figure 4 As shown, in this embodiment, the X-axis moving component 310 includes a gantry frame 311, an X-axis drive component 312, and a guide rail 313. The bottom of the gantry frame 311 is slidably connected to the inner bottom wall of the dock body 100 via the guide rail 313. The X-axis drive component 312 is mounted on the gantry frame 311, and the output end of the X-axis drive component 312 is connected to the guide rail 313 to drive the gantry frame 311 to slide.

[0033] The gantry 311 includes a frame 311a and two legs 311b. The bottom of both sides of the frame 311a is connected to the two legs 311b respectively. The two legs 311b provide a certain installation height for the frame 311a. The bottom of the legs 311b is slidably connected to the guide rail 313. The X-axis drive component 312 can be a drive wheel installed on the legs 311b. The drive wheel is connected to the guide rail 313. The rotation of the drive wheel generates friction with the guide rail 313, thereby driving the gantry 311 to move.

[0034] It is understood that the aforementioned drive wheel includes a drive motor and a rotating wheel. The rotating wheel is rotatably connected to the gantry 311 and abuts against the guide rail 313. The drive motor is mounted on the gantry 311 and its output end is connected to the rotating wheel. The number of drive wheels can be set to multiple.

[0035] like Figure 5 As shown, in this embodiment, the Y-axis moving component 320 includes a top plate 321 and a Y-axis driving component 322. The top plate 321 is slidably disposed on the top of the gantry frame 311, and the Y-axis driving component 322 is mounted on the gantry frame 311 with its output end connected to the top plate 321 for driving the top plate 321 to slide. It can be understood that the top plate 321 and the gantry frame 311 can be connected by a slider or a groove to limit the sliding direction of the top plate 321.

[0036] The Y-axis drive unit 322 includes a first motor 322a, a first gear 322b, and a first rack. The first rack is mounted on the gantry frame 311, the first motor 322a is mounted on the top plate 321, the output end of the first motor 322a is connected to the first gear 322b, and the first gear 322b is meshed with the first rack.

[0037] like Figure 6 As shown, in this embodiment, the Z-axis moving component 330 includes a guide frame 331, a sliding column 332, and a Z-axis driving component 333. The guide frame 331 is fixedly disposed in a through hole opened on the top plate 321. The sliding column 332 passes through the guide frame 331 in the vertical direction and is slidably connected to the guide frame 331. The Z-axis driving component 333 is mounted on the guide frame 331 and its output end is connected to the sliding column 332 for driving the sliding column 332 to move in the vertical direction. The bottom of the sliding column 332 is connected to the high-pressure water jet cutting assembly 400.

[0038] The Z-axis moving component 330 includes a second motor, a worm gear reducer 333a, a gear shaft 333b, a second gear 333c, and a second rack 333d. The second motor is mounted on the top plate 321, and both the second motor and the worm gear reducer 333a are mounted on the top plate 321. The gear shaft 333b is rotatably connected to the guide frame 331. The output end of the second motor is connected to the gear shaft 333b via the worm gear reducer 333a. The second gear 333c is disposed on the gear shaft 333b. The second rack 333d extends vertically and is fixedly disposed on the sliding column 332. The second gear 333c and the second rack 333d are meshed together.

[0039] To limit the sliding direction of the sliding column 332, the guide frame 331 and the sliding column 332 can be connected by a slider or a groove. Alternatively, the guide frame 331 and the sliding column 332 can be connected by a pulley 332a. Specifically, the pulley 332a is rotatably connected to the sliding column 332, and the pulley 332a abuts against the inner wall of the guide frame 331.

[0040] Of course, in other preferred embodiments, the three-axis moving platform 300 may also adopt other forms of structure, and there is no limitation on this.

[0041] The high-pressure water jet cutting assembly 400 in this embodiment utilizes high-pressure water jets to perform hydraulic cutting on ships. Compared to flame cutting, this effectively improves cutting accuracy, reduces material loss (energy consumption required for flame cutting), and reduces harmful substances (harmful gases generated during the cutting process). Specifically, the high-pressure water jet cutting assembly 400 is connected to the moving end of the three-axis moving platform 300, and the high-pressure water jet cutting assembly 400 has a high-pressure water jet cutting end.

[0042] like Figure 7As shown, in one embodiment, the high-pressure water jet cutting assembly 400 includes a nozzle 410 connected to the output end of a three-axis moving platform 300. One end of the nozzle 410 is a nozzle 411, and the other end is an inlet 412 for receiving external high-pressure water. It is understood that the diameter of the nozzle 411 should be smaller than the diameter of the rest of the nozzle 410 to increase the water velocity exiting the nozzle 410.

[0043] To facilitate the nozzle 410 cutting the ship along a predetermined trajectory, in one embodiment, the high-pressure water jet cutting assembly 400 further includes a robot arm 420, which is connected to the output end of the three-axis moving platform 300, and the gripping end 421 of the robot arm 420 is connected to the nozzle 410.

[0044] It is understandable that the robotic arm 420 is a structure that can be conceived by those skilled in the art, such as a three-axis robotic arm 420 or a six-axis robotic arm 420, to improve the flexibility of the nozzle 410 movement.

[0045] like Figure 8 As shown, in this embodiment, the high-pressure water jet cutting assembly 400 further includes a booster 430, a feeder, and a water pump. The booster 430 has a booster chamber, and an inlet 431, an abrasive inlet 432, and an outlet 433 connected to the booster chamber. The outlet end of the feeder is connected to the abrasive inlet 432 of the booster 430. The water pump is connected to the inlet 431 of the booster 430. The outlet 433 of the booster 430 is connected to the inlet 412 of the nozzle 410.

[0046] It is understandable that the inside of the booster 430 is divided into the aforementioned booster chamber by a piston. Valves are installed at the water inlet 431, abrasive inlet 432, and water outlet 433. In operation, water and abrasive are transported to the booster chamber by a water pump and a feeder. The piston moves, the volume of the booster chamber decreases, and the pressure increases. When the pressure in the booster chamber increases to a preset value, the valve at the water outlet 433 opens, thereby transporting the mixture of abrasive and water to the nozzle 410, thus realizing the water cutting operation.

[0047] Of course, in another embodiment, the pressure of the booster 430 can be adjusted, and the valve of the abrasive inlet 432 can be closed, so that the nozzle 410 sprays water at a lower pressure to clean the ship.

[0048] The negative pressure suction assembly 500 in this embodiment is used to collect and store waste liquid generated during dismantling and cleaning operations within the dismantling pool 110. Specifically, the negative pressure suction assembly 500 has a recovery end connected to the bottom of the dock body 100 for recovering the waste liquid.

[0049] In one embodiment, the negative pressure suction assembly 500 includes a storage container, a suction pump, and a connecting pipe. The inlet of the suction pump is connected to the bottom of the dock body 100 via the connecting pipe, and the outlet of the suction pump is connected to the storage container.

[0050] This embodiment also includes a crane 600 installed on a three-axis moving platform 300, which drives the crane 600 to move horizontally. Specifically, the crane 600 is installed on the top plate 321 and can move along with the high-pressure water jet cutting assembly 400. It can promptly lift the cut parts to the stacking position on the main body of the dock 100, preventing parts from falling and damaging the hull below after cutting, thus affecting subsequent cutting work.

[0051] It is understandable that the number of cranes 600 can be set to two, and the two cranes 600 can be set sequentially on the top plate 321 along the X-axis. The cranes 600 can be double-beam gantry cranes, which is a structure that can be conceived by those skilled in the art, and will not be elaborated or explained in detail here.

[0052] This embodiment also includes a photovoltaic power generation module 700 installed on top of the dock hull 100. In one embodiment, it also includes a solar panel, an inverter, a transformer, a photovoltaic combiner box, and cables. The current generated by the solar panel is collected by the cables to the inverter to power the equipment inside the dock. It is understood that the photovoltaic power generation module 700 described above is a conventional structure that will be conceived by those skilled in the art, and will not be elaborated or described in detail here.

[0053] In one embodiment, the top of the enclosed dock features a space truss structure covered with solar panels to fully utilize natural conditions and power dismantling operations within the dock. The solar panels employ bifacial power generation modules and adaptive tilt modules to increase daily power generation. Specifically, the bottom of the solar panels is equipped with automatically adjustable supports, working in conjunction with an intelligent controller to ensure efficient power generation even under uneven sunlight conditions. The current generated by the solar panels is collected via cables to an inverter to power equipment within the dock.

[0054] This embodiment also includes an air handling unit installed within the dock body 100 to treat the air within the dock body 100. During the dismantling process, it is unavoidable that asbestos fibers will be released, heavy metal particles will be suspended, and toxic and harmful volatile organic compounds will be emitted without proper control. Therefore, the air handling unit can collect, adsorb, or treat the aforementioned pollutants.

[0055] It is understandable that the aforementioned air handling components can be implemented using structures such as sprayers, air purifiers, and dust collectors.

[0056] Workflow: After the vessel is fully inserted into the main dock 100, the dock gate 200 is closed, forming a closed dismantling space. The rough dismantling pool is drained (using a water pump), allowing the scrapped vessel to be placed on the keel supports set on the bottom wall of the pool. Once the hull is stably positioned, the pre-treatment stage begins immediately. After pre-treatment is completed and the dock environment is confirmed to be safe, the airtight dock gate 200 is closed. Upon receiving a command from the terminal, the three-axis moving component drives the crane 600 and the high-pressure water jet cutting assembly 400 to the designated cutting position. This allows the crane to move along the X, Y, and Z axes to complete the segmented cutting, covering the entire working surface of the hull. After the hull is cut into several segments, the booster 430 adjusts the water pressure and switches to cleaning mode to clean the larger segments for direct recycling. The water, oil, and some waste residue in the rough dismantling pool are treated by the negative pressure suction assembly 500 for easy recycling. The larger, stronger components within the section are then removed using a high-pressure water jet assembly. Subsequently, a crane 600 lifts the roughly dismantled section and moves it to the fine dismantling pool for further detailed dismantling. The materials are then intelligently sorted for recycling.

[0057] Compared with existing technologies: 1) The embodiments of the present invention adopt a fully enclosed structure to control dust diffusion and oil leakage from the source, and prevent harmful substances such as asbestos from directly spilling into the atmosphere during the dismantling process; 2) The embodiments of the present invention use a bifacial photovoltaic power generation module 700 and an adaptive tilt module, which reduces the overall electricity cost compared with the traditional power supply mode, and simultaneously realizes the composite utilization of land resources and the green transformation of the energy structure; 3) The embodiments of the present invention can be operated unmanned and automatically. After the terminal issues the command, the three-axis moving component drives the crane 600 and the high-pressure water jet cutting component 400 to the designated cutting position, and enables the impact range of the high-pressure water jet cutting equipment to cover the entire working surface of the ship, which greatly improves the cutting efficiency. 4) The embodiments of the present invention are applied to the scenario of ship hull cutting and cleaning. The intelligent cutting method replaces manual operation, which can not only reduce the risk of safety accidents, but also greatly improve the efficiency of ship hull cutting and realize green and intelligent ship dismantling. 5) The embodiments of the present invention utilize water jet cold cutting, which, compared with traditional flame cutting, can solve problems such as low cutting accuracy, large material loss, and large-scale dust and diffusion of harmful substances, reduce workers' contact with dangerous substances such as asbestos, and greatly reduce the safety risks of manual operation. 6) In this embodiment of the invention, the contraction at the nozzle 411 of the nozzle 410 further increases the flow rate of the high-pressure water, significantly improving the cutting effect; 7) In this embodiment of the invention, the gantry 311, the crane 600 and the robotic arm are used to form a three-dimensional collaborative motion mode, which carries the entire set of cutting equipment to move along the X-axis, Y-axis and Z-axis directions, so that the cutting range of the high-pressure water jet cutting component 400 can cover the entire working surface of the ship and can also achieve "one machine for two purposes".

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
