Description

Technical Field

[0001] The invention patent relates to the field of submarine data cabin operation and maintenance, and in particular to a submarine lifting and maintenance device and a method of using the same. Background Art

[0002] With the rapid development of information technology, the demand for data centers continues to increase. To meet the heat dissipation requirements for large-scale data storage and processing, using the seabed as a cooling environment for data center data cabins has become an emerging solution. However, the maintenance and inspection of data cabins face many challenges: Due to their location on the seabed, traditional inspection methods require divers to perform underwater operations, which is not only inefficient but also poses a high safety risk. In addition, the complex marine environment, with factors such as currents and waves posing a threat to the stability of data centers. At the same time, offshore wind power, as an important renewable energy source, requires stable support for its infrastructure, such as jackets and floating foundations, in the marine environment. Therefore, how to ensure the stable operation of the data cabin while improving its operation and maintenance efficiency and reducing its operation and maintenance costs has become a technical problem that needs to be solved urgently.

[0003] Maintenance issues: Once a data pod is submerged, its repair becomes exponentially more difficult. Unlike land-based data centers, underwater data pods are virtually impossible to maintain during normal operation. The typical recovery cycle for a data pod is as long as five years. During this period, if a device malfunctions, technicians cannot quickly access the equipment room for troubleshooting and repair, as they can on land. The harsh underwater environment, characterized by high pressure, darkness, and complex water currents, poses significant obstacles for divers. Even experienced divers face the risk of decompression sickness when performing underwater repairs, and each operation is subject to strict time and depth restrictions. Furthermore, underwater data pods contain numerous delicate data components, and the tanks have numerous openings for pipelines and cables. After prolonged exposure to seawater pressure and corrosion, any carelessness during repairs could cause secondary damage to the equipment, further exacerbating losses. Furthermore, the specialized equipment and tools required for underwater repairs are expensive, and training maintenance personnel is a significant resource.

[0004] Problems with heat dissipation and maintenance in submarine data pods have severely hampered their widespread deployment and application. Undersea currents and undercurrents impact the data pods, preventing them from maintaining long-term stability. Overcoming these challenges requires collaborative innovation among researchers and engineers in multiple fields, including materials science, heat exchange technology, and underwater equipment, to explore more efficient and reliable solutions. Only then can submarine data centers truly become a mainstay in the data storage and processing industry.

[0005] In summary, it is of great significance to develop an efficient, economical and reliable operation and maintenance auxiliary equipment suitable for data cabins. Summary of the Invention

[0006] The present invention aims to solve the problem of submarine data cabins being washed away and tilted by water, and to solve the problem of rapid, efficient, safe lifting and maintenance of data cabins during maintenance.

[0007] In order to solve the above problems, the present invention combines the data cabin with the offshore lifting and operation and maintenance device, which is specifically achieved through the following methods: A submarine lifting and maintenance device comprises a first steel plate seat, wherein the bottom wall of the first steel plate seat is fixedly connected to a first fixing seat. Each groove on the top of the first steel plate seat is fixedly connected to the top end of the rack, and each groove on the bottom of the second fixed seat is fixedly connected to the bottom end of the rack. A gear rotates on the tooth wall of each rack, and each gear is fixedly connected to the output end of the motor. Each motor is fixedly connected to the center bracket.

[0011] The bottom of the central support is also fixedly connected with a plurality of electromagnetic support feet, and the central support is also fixedly provided with a plurality of drainage holes.

[0012] The top side wall of the central support is also fixedly connected to a plurality of wave groove plates, the wave grooves of each wave groove plate are arranged in parallel, and the concave surface of the wave groove is fixedly connected to a permanent magnet.

[0013] The two racks on the same side of the second fixing base form an eight-shaped angle, and the two racks on the other side of the second fixing base are symmetrically arranged therewith.

[0014] The top of each rack is fixedly connected to each groove of the first fixing seat, and the groove of each first fixing seat is also fixedly equipped with a proximity switch. The first fixing seat is fixedly connected to the first steel plate seat, and the first steel plate seat is fixedly connected to the top of each gravel pile; the bottom end of each rack is fixedly connected to each groove of the second fixing seat, and the groove of each second fixing seat is also fixedly equipped with a proximity switch. The second fixing seat is fixedly connected to the second steel plate seat, and the second steel plate seat is fixedly connected to the bottom of each gravel pile.

[0015] The top side wall of the central bracket is also fixedly connected to a plurality of grippers, each gripper is fixedly installed near one side of each rack, and when the clamping mouth of each gripper is combined, the clamping mouth of each gripper is fixedly clamped on the side wall of each rack, and a plurality of small protrusions are evenly provided on the inner side wall of the clamping mouth, and the spacing of the small protrusions is equal to the spacing of the teeth of the rack.

[0016] The method for using the submarine lifting and maintenance device comprises the following steps: S1. When repairing the data cabin, lift the center bracket to the bottom of the first fixing seat; S2. After the data cabin maintenance is completed, put the center bracket back on the top of the second steel plate seat. In step S1, when the center support is lifted, the controller turns off the electromagnetic support legs, opens the jaws of the gripper, and starts the forward drive of the motor. When the device rises to the proximity switch of the first fixed seat, the controller turns off the motor and closes the jaws of the gripper. In step S2, when the center support is lowered, the controller opens the jaws of the gripper and starts the reverse drive of the motor. When the device descends to the proximity switch of the second fixed seat, the controller turns off the motor, starts the electromagnetic support legs, and merges the jaws of the gripper.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Improve operation and maintenance efficiency: The data cabin is lifted to the surface of the water through a lifting mechanism, allowing operation and maintenance personnel to perform inspections and maintenance in a relatively safe environment, avoiding the risks of diving operations and significantly improving operation and maintenance efficiency.

[0018] 2. Enhanced operational stability: The bottom of the device is fixed to the seabed, and the top is connected to the offshore wind turbine foundation. The gravel piles are conical columns, which reduce water resistance. The cylindrical frame structure provides stability during the lifting process, ensuring stable operation of the data cabin in complex marine environments.

[0020] 4. This invention provides a lifting and maintenance device for a data cabin that works in conjunction with offshore wind turbines. This device enables efficient and safe operation and maintenance of the data cabin, while leveraging the offshore wind turbine infrastructure to improve overall stability. This device can also serve as a counterweight for the foundation of an offshore wind turbine, leveraging its own weight and structural stability to enhance the turbine's ability to withstand wind and wave conditions in harsh marine environments.

[0021] 5. The permanent magnet firmly adsorbs the stainless steel bracket of the data cabin, and the concave surface of the wavy groove fixes the stainless steel bracket of the data cabin placed above. The wavy structure is set to prevent the horizontal undercurrent water on the seabed from washing away the data cabin. The permanent magnet is set to firmly adsorb and fix the data cabin to prevent the vertical undercurrent water on the seabed from washing away the data cabin.

[0022] 6. The present invention sets drainage holes on the data center bracket to reduce the fluid resistance of the device when rising or falling. The present invention sets the angle between the axis of the motor and the gear and the central symmetry line of the device according to the setting of the angle α. The angle α is 5°~8°. If the angle α is too large, the load on the output end of the motor will increase. If the angle α is too small, when the submarine undercurrent is large, the horizontal push of the data cabin and the center bracket may cause the side wall of the center bracket to contact the side wall of the rack, resulting in an increase in the motor load or the motor being stuck, and the four gears cannot effectively play a limiting role in fixing the center bracket.

[0075] The second steel plate seat 5 is a steel plate with a surface painted with waterproof and anti-corrosion paint. The second steel plate seat 5 can be adsorbed by a magnet and fixed to the seabed to ensure the stability of the device in the marine environment.

[0076] The angle between the axis of the motor 6 and the gear 4 and the central symmetry line of the device is set according to the setting of the angle α, and the angle α is 5°~8°. When the angle α is too large, greater than 8°, the load on the output end of the motor 6 will increase. When the angle α is too small, less than 5°, when the velocity of the submarine undercurrent is large, the ocean current and the undercurrent may push the data cabin and the center bracket 7 horizontally, causing the side wall of the center bracket 7 to contact the side wall of the rack 3, resulting in an increase in the load on the motor 6 or the motor 6 being stuck, and the four gears 4 cannot effectively play a limiting role in fixing the center bracket 7.

[0077] like Figure 7 As shown, the two racks 3 on the same side of the second fixing base 501 form an eight-shaped angle, and the two racks 3 on the other side of the second fixing base 501 are symmetrically arranged therewith.

[0078] The outer surface of each rack 3 and each gear 4 is coated with a layer of waterproof and anti-corrosion paint.

[0079] A gear 4 and a rack 3 mechanism are provided inside the device of the present invention. The gear 4 is driven by a motor 6. The top and bottom ends of the rack 3 are fixedly connected to the first fixing seat 101 and the second fixing seat 501 respectively.

[0080] The cylindrical rack 3 of the device of the present invention is made of high-strength steel, and a plurality of teeth are provided on the inner wall of the rack 3. The teeth of the gear 4 are in rotational contact with the teeth on the inner wall of the rack 3. When the motor 6 rises to the vicinity of the first fixed seat 101 and stops running, the inner wall of the rack 3 and the teeth of the gear 4 can be fixedly engaged to support the central bracket 7 and maintain the stability of the central bracket 7, thereby maintaining the stability of the data cabin placed on the central bracket 7.

[0081] The operation process of the device of the present invention is as follows: When the data cabin on the seabed needs to be repaired, the power supply of the data cabin is turned off to stop its operation.

[0082] At this time, the PLC controller starts the motor 6, opens the jaws 901 of the gripper 9, closes the electromagnetic support foot 701, and the motor 6 drives the gear 4 to rotate. The gear 4 pulls the data cabin along the cylindrical frame to the water surface through the rack 3. When the data cabin moves to the bottom of the first steel plate seat 1 near the sea water, the motor 6 is turned off, and the jaws 901 of the gripper 9 are merged. Each jaw 901 clamps each rack 3. The first steel plate seat 1 is close to the sea water surface, which allows divers to directly perform inspection and maintenance operations in shallow waters. In the process of lifting the central bracket 7, the two pairs of racks 3 on both sides of the second steel plate seat 5 are arranged in an eight-shaped pattern. To ensure that the data cabin rises smoothly, operation and maintenance personnel can inspect and maintain the data cabin near the water surface.

[0083] After the maintenance of the data cabin is completed, the second steel plate base 5 is put back on the seabed and then the power supply of the data cabin is started to make it run normally.

[0084] At this time, the PLC controller drives the motor 6 in reverse to open the jaws 901 of the gripper 9. Each jaw 901 releases each rack 3 until the four electromagnetic feet 701 land on the second steel plate seat 5. At this time, the data cabin on the center bracket 7 falls back onto the second steel plate seat 5. The PLC controller turns on the electromagnetic feet 701 to adsorb the second steel plate seat 5 and merges the jaws 901 of the gripper 9.

[0085] During operation, the first fixing seat 101, the first fixing seat 101, the second steel plate seat 5, the second fixing seat 501, and the gravel pile 2 serve as the counterweight of the device, using their own weight and structural stability to improve the device's ability to resist wind and waves.

[0086] The second steel plate seat 5 fixes the bottom of the device to the seabed to ensure the stability of the device in the marine environment.

[0087] A gear 4 and a rack 3 are provided inside the device, and the gear 4 is driven by a motor 6 .

[0088] The rack 3 is used to guide the lifting and lowering movement of the data cabin and maintain its stability.

[0089] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. In other words, equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
