However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a corrosion-resistant and highly sealed rotary compensator, including a mounting base 1, a rotating cylinder 2 is arranged inside the mounting base 1; a sealing assembly 5, the sealing assembly 5 is fixedly connected to the top of the mounting base 1, the sealing assembly 5 includes a fixed ring 501, a connecting ring 502 is fixedly connected to the top of the fixed ring 501, a plurality of through holes 509 are evenly opened on the inner surface of one side of the connecting ring 502, a plurality of springs 510 are evenly fixedly connected to the inner surface of the other side of the connecting ring 502, a snap ring 511 is fixedly connected to the end surface of the spring 510, and a ball 512 is arranged on the inner surface of the snap ring 511. The number of balls 512 is equal to the number of through holes 509 and the spacing is the same.

[0022] As Figures 1-4 shown, the connecting ring 502 is located outside the rotating cylinder 2, the ball 512 is located between the snap ring 511 and the inner surface of the connecting ring 502, the ball 512 is located inside the through hole 509, and through the arrangement of the spring 510, the snap ring 511 is driven by the resilience of the spring 510 to clamp the ball 512 inside the through hole 509. Therefore, in the static state, the position of the through hole 509 is closed.

[0023] As Figures 1-4 shown, a groove 3 is opened on the outer surface of the rotating cylinder 2, and a sealing ring 4 is arranged at the bottom of the groove 3. When the rotating cylinder 2 is stressed and rotates, the sealing ring 4 will frictionally contact the ball 512 and drive the ball 512 to roll. Through the rolling of the ball 512, the lubricating oil inside the connecting ring 502 can be taken out.

[0024] As Figures 1-4As shown, the ball 512 is located at the inner position of the groove 3, and the outer surface of the ball 512 is in contact with the outer surface of the sealing ring 4. The lubricating oil brought out can fill the groove 3, so that there is an oil seal layer at the gap between the mounting seat 1 and the rotating cylinder 2.

[0025] As Figures 1-4 shown, the top of the connecting ring 502 is fixedly connected to the sealing cover 503. A plurality of side pipes 504 are uniformly and fixedly connected to the outer surface of the connecting ring 502. A supply ring 505 is fixedly connected between the end faces of the plurality of side pipes 504. After unscrewing the threaded cap 507 and opening it, lubricating oil can be filled into the supply ring 505 through the filling port 506, and the added lubricating oil will flow into the connecting ring 502 through the side pipes 504.

[0026] As Figures 1-4 shown, a plurality of side holes 508 are uniformly formed on the outer surface of the connecting ring 502. The side holes 508 are arranged in a matching manner with the side pipes 504. The filling port 506 is fixedly connected to the top of the supply ring 505. The threaded cap 507 is threadedly connected to the outer surface of the filling port 506. The filling port 506 is in a communicating setting with the supply ring 505. After filling is completed, the connecting ring 502 stores lubricating oil with corrosion resistance properties for use.

[0027] The usage method and working principle of this device: When the rotary compensator is in use, the rotating seat structure inside the mounting seat 1 provides support for the rotating cylinder 2, enabling the rotating cylinder 2 to rotate freely. After connecting the rotating cylinder 2 to the pipeline, the rotating cylinder 2 is used to compensate for the forces, torques, angles, displacements, etc. generated during the deformation and displacement of the pipeline to protect the safe operation of the pipeline. During the use of the rotary compensator, through the use of the sealing assembly 5, the gap between the mounting seat 1 and the rotating cylinder 2 can be strengthened and sealed to prevent the rotating structure from being corroded due to the long-term exposure of the gap position to the air. After unscrewing the threaded cap 507 and opening it, lubricating oil can be filled into the supply ring 505 through the filling port 506, and the added lubricating oil will flow into the connecting ring 502 through the side pipes 504, so that the connecting ring 502 stores lubricating oil with corrosion resistance properties. And through the setting of the spring 510, the resilience of the spring 510 drives the snap ring 511 to clamp the ball 512 at the inner side position of the through hole 509. Therefore, in the static state, the through hole 509 is closed. When the rotating cylinder 2 is subjected to force and rotates, the sealing ring 4 will frictionally contact the ball 512 and drive the ball 512 to roll. Through the rolling of the ball 512, the lubricating oil inside the connecting ring 502 can be brought out, and the brought-out lubricating oil can fill the groove 3, so that there is an oil seal layer at the gap between the mounting seat 1 and the rotating cylinder 2. Through the setting of the oil seal, the gap position can be sealed and protected to prevent corrosion and damage to the inside of the mounting seat 1 and the rotating cylinder 2. At the same time, when the rotating cylinder 2 is running, it can drive the ball 512 to roll continuously to bring out lubricating oil to supplement the oil seal layer, eliminating the need for manual maintenance and reducing the maintenance cost of the rotary compensator.
