Description

Technical Field

[0001] This invention relates to the field of ship transfer technology, specifically to a quick-connect structure for the outer side of a ship's ballast water inlet and outlet. Background Technology

[0002] Ballast water refers to water added to a ship to control its list, trim, draft, stability, or stress. Ballast water typically originates from the ship's port of origin or coastal waters along its route. The significant harm ballast water poses to the marine environment has been recognized by the Global Environment Facility (GEF) as one of the four major threats to the ocean. Therefore, ballast water treatment is necessary to prevent the spread of marine life via ballast water. Existing technologies for transferring ballast water to shore for treatment often suffer from inaccurate docking between the receiving port and the discharge port, leading to increased docking time, reduced efficiency, and compromised safety. Therefore, a rapid docking structure for the external connection of ballast water receiving and discharge ports is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing a simple, rationally designed, and easy-to-use quick-connection structure for the ship's ballast water inlet and outlet, which can solve the technical problems in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it includes a hydraulic robotic arm and a transfer pipe. The hydraulic robotic arm is connected to the transfer pipe through an external ship ballast water overboard transfer device. The transfer pipe's transfer joint is inserted into the port of the ship's ballast water discharge pipe. The hydraulic robotic arm is connected to an external hydraulic pump station through hydraulic pipelines. The end of the hydraulic robotic arm is connected to a bracket through an angle adjuster.

[0005] A semi-circular electro-permanent magnet chuck is fixedly mounted at the end of a bracket and magnetically attracted to a steel flange fixedly fitted on the outer wall of the transfer joint of the transfer pipe. The steel flange has a semi-circular structure. The semi-circular electro-permanent magnet chuck is connected to an external electro-permanent magnet control box via a magnetic chuck cable.

[0006] The underwater camera consists of several underwater cameras, all of which are fixedly mounted on a semi-circular electro-permanent magnet chuck. The underwater cameras are connected to an external camera display terminal via video cables.

[0007] An inflatable sealing ring is fixedly sleeved on the outer wall of the adapter joint of the adapter pipe, and the outer wall of the inflatable sealing ring is movably in contact with the inner wall of the port of the ballast water discharge pipe; the inflatable sealing ring is connected to the delivery end of an external air compressor through a compressed air pipeline.

[0008] A positioning and locking hydraulic cylinder assembly is installed on the transfer joint of the transfer pipe.

[0009] Through the above technical solution design, the end of the deployed hydraulic robotic arm is fixed on shore using an electro-permanent magnet chuck to the end of the transfer pipe joint (including the delivery hose, compressed air hose, and positioning mechanism hydraulic hose from the external ballast water overboard transfer device). The hydraulic robotic arm then enters the seawater near the ballast water discharge pipe. The approximate location of the ballast water discharge pipe is determined by referring to data provided by the ship. An underwater camera mounted on the electro-permanent magnet chuck scans the ship's hull vertically and horizontally to locate the specific position of the ballast water discharge pipe. After locating the ballast water discharge pipe, the end of the electro-permanent magnet chuck is used to... The underwater cameras, mounted in the X and Y directions, are used to adjust the gap between the transfer joint of the transfer pipe and the ballast water discharge pipe. After aiming, the hydraulic robotic arm moves the transfer pipe into the ballast water discharge pipe. The control console positions and locks the transfer pipe in the ballast water discharge pipe through hydraulic lines, and inflates the air seal between the transfer pipe and the inner wall of the ballast water discharge pipe through compressed air lines. After the above two actions are completed, the control console powers on the electro-permanent magnet chuck to eliminate the magnetic attraction of the electro-permanent magnet chuck. The electro-permanent magnet chuck then detaches from the transfer pipe along with the hydraulic robotic arm and separates from the hull.

[0010] The overall retraction action of the transfer pipe involves lowering the electro-permanent magnet chuck at the end of the hydraulic robotic arm, which is suspended vertically, to the position of the transfer pipe, pressing it against the steel flange, and then releasing the pressure inside the inflatable sealing ring and positioning locking hydraulic cylinder assembly. After that, the electro-permanent magnet chuck is energized, and the joint of the transfer pipe is withdrawn through magnetic attraction and the movement of the hydraulic robotic arm. The remaining actions are performed in reverse according to the installation procedure to complete the retraction of the transfer pipe and hose.

[0011] As a further improvement of the present invention, the positioning and locking hydraulic cylinder assembly includes:

[0012] Four guide rods are fixedly mounted in a conical shape on the transfer joint of the transfer pipe.

[0013] The hydraulic cylinder consists of six sets, four of which are fixedly mounted on the ends of the guide rods, and the ends of the push rods of these four sets of hydraulic cylinders are in contact with the inner side wall of the ballast water discharge pipe; the cylinder sleeves of the other two sets of hydraulic cylinders are fixedly connected to the side wall of the transfer pipe.

[0014] Through the above technical solution design, the external thrust of six sets of hydraulic cylinders is used to press against the inner wall of the ballast water discharge pipe to form a fixed support frame; the thrust of each set of hydraulic cylinders is 1 ton, and the total thrust generated by the six sets simultaneously reaches six tons, which can meet the head fixing requirements of the 50Kg transfer pipe.

[0015] As a further improvement of the present invention, the four guide rods are arranged in a tapered structure on the transfer joint of the transfer pipe.

[0016] As a further improvement of the present invention, the wall thickness of the part of the steel flange that contacts the ship is 20mm.

[0017] As a further improvement of the present invention, both the air compressor and the hydraulic pump station are mounted on the tower of the hydraulic robotic arm.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. It ensures that the transfer head of the transfer pipe is accurately and quickly connected to the discharge port of the ballast water discharge pipe, and can fix the transfer pipe inside the ballast water discharge pipe outside the ballast water discharge port, ensuring that the outward thrust generated by the discharge of ballast water from the tank cannot move the transfer pipe, thus ensuring the safe transfer of ballast water to the shore.

[0020] 2. The quick hooking and unhooking of the hydraulic robotic arm end to the transfer pipe reduces the slight swaying effect of wind and waves on the ship. The hydraulic robotic arm and the ship cannot have rigid contact for a long time, reducing the occurrence of safety accidents. Attached Figure Description

[0030] The invention will now be further described with reference to the accompanying drawings.

[0031] Example 1:

[0032] See as Figure 1-6 As shown, this embodiment includes a hydraulic robotic arm 1 and a transfer pipe 2. The hydraulic robotic arm 1 is connected to the transfer pipe 2 via an external ship ballast water outboard transfer device. The transfer pipe 2's transfer head is inserted into the port of the ship's ballast water discharge pipe 3. The hydraulic robotic arm 1 is connected to an external hydraulic pump station 5 via a hydraulic pipeline 4. The end of the hydraulic robotic arm 1 is connected to a bracket 7 via an angle adjuster 6.

[0033] A semi-circular electro-permanent magnetic chuck 8 is fixedly mounted at the end of the bracket 7 and magnetically attracted to a steel flange 9 fixedly sleeved on the outer wall of the adapter joint of the adapter pipe 2. The steel flange 9 adopts a semi-circular structure with a thickness of δ=20mm. The semi-circular electro-permanent magnetic chuck 8 is connected to an external electro-permanent magnetic disk control box 11 through a magnetic chuck cable 10. The selected semi-circular electro-permanent magnetic chuck 8 and the steel flange 9 are based on the principle of instantaneous adsorption and instantaneous de-adsorption to achieve the requirements of quick hooking and quick unhooking. The semi-circular electro-permanent magnetic chuck 8 generates a magnetic field to attract the steel flange 9 after energizing for 1 second. The magnetic field is eliminated and the steel flange 9 is released after 1 second of energization. The relevant parameters of the electro-permanent magnetic chuck are: working voltage: DC170V; working current: DC60A; magnetic attraction force: >1000KG; protection level: IP68; nickel-plated surface for corrosion protection; equipped with a controller to control the energization and discharging of the electro-permanent magnetic chuck. The wiring between the controller and the electro-permanent magnetic chuck is provided by the manufacturer, with a length of 30 meters. A single 3φ, 380V power supply to the controller enables the function. The semi-circular flange-type electro-permanent magnetic chuck was designed and developed for more convenient and flexible gripping of circular pipe-type transfer connections.

[0034] Several underwater cameras 12 are fixedly mounted on a semi-circular electro-permanent magnet chuck 8. The underwater cameras 12 are connected to an external camera display terminal 18 via video cables 13. Each underwater camera 12 has a 316L stainless steel shell resistant to seawater corrosion and a 2-megapixel high-definition / AHD resolution with supplemental lighting. The underwater cameras 12 are fixed to an electromagnetic chuck at the end of the hydraulic robotic arm 1. The scanned image is fed back to the external camera display terminal 18 via the video cables 13. The operator judges the image from the terminal and issues corresponding operation commands. The video cables 13 connect the external camera display terminal 18 and the underwater cameras 12 along the hydraulic robotic arm 1.

[0035] An inflatable sealing ring 14 is fixedly sleeved on the outer wall of the adapter joint of the adapter pipe 2, and the outer wall of the inflatable sealing ring 14 is in movable contact with the inner wall of the port of the ballast water discharge pipe 3. The inflatable sealing ring 14 is connected to the delivery end of the external air compressor 16 through the compressed air pipeline 15. Considering the irregularity of the pipe opening of the ballast water discharge pipe 3 and the unevenness caused by the corrosion of the inner wall of the ballast water discharge pipe 3, an inflatable sealing ring 14 is installed on the outer wall of the adapter pipe 2. After the connection is completed, 0.8MPa compressed air is used to inflate and tighten the inner wall of the ballast water discharge pipe 3 to compensate for the defects of the inner wall of the ballast water discharge pipe 3 and achieve the pressure required to seal the ballast water discharge.

[0036] Positioning and locking hydraulic cylinder assembly 17 is installed on the transfer joint of transfer pipe 2.

[0037] Example 2:

[0038] See as Figure 1-6 As shown, based on Embodiment 1, the positioning and locking hydraulic cylinder assembly 17 includes:

[0039] Guide rod 17-1, there are four guide rods 17-1, which are fixedly installed in a conical shape on the transfer joint of the transfer pipe 2;

[0040] Hydraulic cylinders 17-2 consist of six sets, four of which are fixedly mounted at the ends of guide rods 17-1, with the top rod ends of these four sets of hydraulic cylinders 17-2 abutting against the inner wall of ballast water discharge pipe 3; the cylinder sleeves of the other two sets of hydraulic cylinders 17-2 are fixedly connected to the side wall of the transfer pipe 2; the hydraulic pump station 5 outputs a 14MPa high pressure, which is connected to the positioning and locking hydraulic cylinder assembly of the transfer pipe 2 through a 1 / 4-inch hydraulic hose. Before the transfer pipe 2 is launched into the water, it is quickly docked at the shore via a quick connector and launched into the water. The total length is expected to be 30m.

[0041] When using this invention, the end of the extended hydraulic robotic arm 1 is fixed on shore by an electro-permanent magnet chuck to the end of the transfer pipe connector (including the delivery hose, compressed air hose, and positioning mechanism hydraulic hose of the external ship ballast water overboard transfer device). The hydraulic robotic arm 1 then enters the seawater near the ballast water discharge pipe 3. The approximate location of the ballast water discharge pipe 3 is determined by referring to data provided by the ship. The underwater camera 12 installed on the electro-permanent magnet chuck scans the ship's hull vertically and horizontally to locate the specific position of the ballast water discharge pipe 3. After locating the ballast water discharge pipe 3, the underwater cameras 12 installed in the X and Y directions on the end electro-permanent magnet chuck are used to adjust the transfer connector of the transfer pipe 2 to the pressure... After aiming, the hydraulic robotic arm 1 moves the transfer pipe 2 into the ballast water discharge pipe 3 through the gap between the ballast water discharge pipes 3. The external thrust of six sets of hydraulic cylinders 17-2 pushes against the inner wall of the ballast water discharge pipe 3 to form a fixed support frame. The thrust of each set of hydraulic cylinders 17-2 is 1 ton, and the total thrust generated by the six sets simultaneously reaches 6 tons, which can meet the head fixing requirements of the 50Kg transfer pipe 2. The air-filled sealing ring 14 between the transfer pipe 2 and the inner wall of the ballast water discharge pipe 3 is inflated and sealed through the compressed air pipeline 15. After the above two actions are completed, the control console powers on the electro-permanent magnet chuck to eliminate the magnetic attraction of the electro-permanent magnet chuck. The electro-permanent magnet chuck is detached from the transfer pipe 2 along with the hydraulic robotic arm 1 and separated from the hull.

[0042] The transfer pipe 2 is withdrawn as a whole. The electro-permanent magnet chuck at the end of the hydraulic robotic arm 1, which is suspended vertically, is lowered to the position of the transfer pipe 2 and pressed against the steel flange 9. After releasing the pressure inside the inflatable sealing ring 14 and the positioning and locking hydraulic cylinder assembly 17, the electro-permanent magnet chuck is energized. Through magnetic attraction and the movement of the hydraulic robotic arm 1, the joint of the transfer pipe 2 is withdrawn. The remaining actions are performed in reverse according to the installation procedure to complete the retraction of the transfer pipe 2 and the hose.

[0043] The beneficial effects of this specific embodiment after adopting the above structure are as follows:

[0044] 1. It ensures that the transfer head of the transfer pipe 2 is accurately and quickly connected to the discharge port of the ballast water discharge pipe 3, and can fix the transfer pipe 2 inside the ballast water discharge pipe 3 outside the ballast water discharge port, ensuring that the outward thrust generated by the discharge of ballast water from the tank cannot move the transfer pipe 2, thus ensuring the safe transfer of ballast water to the shore.

[0045] 2. The quick hooking and unhooking of the end of the hydraulic robotic arm 1 with the transfer pipe 2 reduces the slight swaying effect of wind and waves on the ship. The hydraulic robotic arm 1 and the ship cannot have a long-term rigid contact, reducing the occurrence of safety accidents.

[0046] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
