The arc surface of the arc-shaped baffle 511 is also in sliding contact with the belt of the pulley group 510. The arc-shaped baffle 511 can ensure the transmission effect of the pulley group 510 to meet the actual transmission requirements. A baffle ring 531 is fixedly installed on the outer surface of the connecting shaft 532. The size of the baffle ring 531 is larger than the size of the threaded hole of the placement plate 52. A frame-shaped protrusion 54 for limiting maintenance tools is fixedly installed on the top surface of the placement plate 52. The frame-shaped protrusion 54 can prevent the maintenance tools from slipping when they are placed on the placement plate 52 and move down.Working principle: When the overall structure is installed, the negative pressure barrel body 1 and the data center cabin 2 are prefabricated as a whole. After the main structure is completed, the server is installed inside the data center cabin 2. After the overall structure is installed, it is transported to a semi-submersible vessel by car. After being transported to the installation site by the semi-submersible vessel, the crane ship applies lifting force and the overall structure is unloaded from the semi-submersible vessel. Subsequently, the negative pressure barrel body 1 opens the exhaust valve to exhaust and sink. During this period, attention is paid to the levelness of the overall structure to maintain the levelness of the structure. Different strategies are adopted to control the levelness during the sinking construction of the negative pressure barrel body 1. The first is before touching the mud and during the deadweight penetration stage. By controlling the lifting load, the penetration rate is adjusted to limit the development of the levelness; the second is the suction penetration stage. By independently controlling the displacement of each compartment of the negative pressure barrel body 1, the pressure difference is independently adjusted, thereby achieving complete leveling. During sinking, the water inlet, drain outlet and inspection port of the data center cabin 2 are all opened to promote rapid exhaust and sinking of the data center cabin 2. After the negative pressure barrel body 1 sinks to the designed elevation, the composite submarine cable is laid and reconnected to the data center cabin 2. When inspecting the data center cabin 2, the inspection channel 41 is first docked and installed with the positioning sleeve 43 at the inspection port of the data center cabin 2. A sealing device is used to ensure a secure connection. The submersible pump 42 and waterproof air intake fan on the inspection channel 41 are activated to remove the seawater between the work surface 45 inside the inspection channel 41 and the cabin door 44 on the data center cabin 2, providing a dry space for maintenance personnel to perform maintenance. The pressure monitor is used to monitor the pressure in the cavity to ensure that the pressure between the channel door 411 and the cabin door 44 is within the normal range. The water immersion monitor can detect water leaks in the cavity and issue an alarm if there is a leak. The work surface 45 inside the inspection channel 41 is provided with sufficient space for opening the channel door 411. The first hydraulic rod 47 and the second hydraulic rod 49 are then activated in sequence. The first hydraulic rod 47 retracts the cabin door 44 into the receiving chamber 46, and the second hydraulic rod 49 pulls the entire receiving chamber 46 to reveal the inspection port of the data center cabin 2.

[0031] When the maintenance personnel enter the data center cabin 2 through the maintenance passage 41 for maintenance, they can first place the maintenance tools on the placement plate 52, and then pass the hanging rope through the connecting ring 57 on the slide 55 to connect the connecting ring 57 to the maintenance personnel through the hanging rope. When the personnel enter the maintenance passage 41 through the embedded stairs 410 inside the maintenance passage 41, the hanging rope pulls the connecting ring 57, the slide 55, the arc-shaped connecting rod 56 and the end seat 512 to form an integral structure downward together, and rotates the transmission gear 513 set on the end seat 512 to engage with the fixed rack 59 fixed on the reinforced cage 51. After the end seat 512 slides down, the transmission gear 513 rotates synchronously, and under the drive of the main bevel gear 515, the secondary bevel gear 516 and its own gear shaft, the worm 517 is driven by the main bevel gear 515, the secondary bevel gear 516 and the gear shaft thereof. They rotate together inside the end seat 512, and the worm 517 is meshed with the worm wheel 518 fixed on the outer surface of the disc shaft 519 for transmission connection, thereby driving the disc shaft 519 inside the end seat 512. The square rod 58, which is rotatably connected to the reinforced cage 51 by the end shaft 581, passes through the end seat 512 and is also slidably connected to the disc shaft 519. The disc shaft 519 can drive the square rod 58 and the end shaft 581 to rotate together, and the end shaft 581 and the connecting shaft 532 are also connected by a synchronous belt drive of the pulley group 510. Therefore, the connecting shaft 532 rotates synchronously with the threaded rod 53, and the threaded rod 53 is also threadedly connected to the placement plate 52. After the threaded rod 53 rotates, the placement plate 52 and the maintenance tools placed on the placement plate 52 can be moved down into the maintenance channel 41 together with the maintenance personnel.
