[0002] As a vital tool in port operations, tugboats rely heavily on their hydraulic systems to power critical equipment such as winches and steering gears. However, during long-term maritime operations, these hydraulic systems face multiple challenges, including seawater corrosion, mechanical vibration, and high-pressure impacts, making them highly susceptible to leaks. A leak can cause a sudden drop in hydraulic system pressure, rendering the tugboat powerless and disrupting normal operations such as berthing and cargo loading / unloading. Furthermore, it can potentially lead to fires due to high-pressure oil jets, causing environmental pollution and major safety accidents.

[0003] Existing quick-sealing connectors for tugboat hydraulic lines have many defects, such as the sealing structure being mostly of fixed size, which makes it difficult to adapt to hydraulic lines of different diameters, resulting in a significant reduction in sealing effect when the pipe diameter changes.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3 An embodiment of this utility model provides a quick-plugging connector for a tugboat hydraulic pipeline, comprising a first water pipe 1, a fixed column 2 fixedly connected to the outer wall of the first water pipe 1, a first dust cover 3 fixedly connected to the outer wall of the fixed column 2, a first control ring 4 slidably connected to the outer wall of the first dust cover 3, a second water pipe 6 slidably connected to the outer wall of the first water pipe 1, a second dust cover 5 fixedly connected to the outer wall of the first dust cover 3, a second water pipe 6 slidably connected to the inside of the second dust cover 5, a second locking tooth 7 fixedly connected to the inside of the first control ring 4, a third spring 8 provided on the outer wall of the second locking tooth 7, and an iris component 9 connected to one end of the third spring 8;

[0026] Specifically, the outer wall of the first water pipe 1 is provided with a groove for quick positioning of the second water pipe 6, and the outer wall of the second water pipe 6 is provided with a groove for clamping the iris assembly 9. The fixing post 2 is used to connect the first water pipe 1 and the first dust cover 3, and the second dust cover 5 is used to seal the siphon assembly. Pushing the first control ring 4 drives the second locking tooth 7 to slide, thereby pushing the third spring 8 to contract, and then the second locking tooth 7 drives the iris assembly 9 to operate, thereby achieving the effect of controlling the operation of the iris assembly 9. The iris assembly 9 is used to stably clamp the second water pipe 6, thereby achieving the effects of pipe diameter adaptive sealing, impact resistance and stability, and quickly shortening the leak-stopping response time.

[0027] Reference Figures 2-4 The iris module 9 includes a second connecting block 901, the outer wall of which is fixedly connected to one end of a third spring 8. A ring 902 is fixedly connected to the outer wall of the second connecting block 901. A first connecting rod 903 is rotatably connected to the outer wall of the ring 902. A blade 904 is rotatably connected to the outer wall of the first connecting rod 903. The outer wall of the blade 904 is snapped into the outer wall of the second water pipe 6. Both the first connecting rod 903 and the blade 904 are rotatably connected to the outer wall of the second dust cover 5. A second connecting rod 11 is slidably connected inside the second water pipe 6. A second control ring 10 is fixedly connected to the upper surface of the second connecting rod 11.

[0028] Specifically, the blade 904 is made of EPDM rubber, the second control ring 10 is arc-shaped, the second connecting block 901 pushes the ring 902 to rotate, the ring 902 drives the first connecting rod 903 to rotate, and the first connecting rod 903 drives the blade 904 to rotate on the outer wall of the first dust cover 3, thereby achieving the effect of adaptive sealing of the pipe diameter.

[0029] Reference Figures 4-5 A sliding arm 12 is fixedly connected to the lower surface of the second connecting rod 11, and the outer wall of the sliding arm 12 is slidably connected to the inside of the second water pipe 6; a first connecting block 13 is slidably connected to the inside of the sliding arm 12, and a first spring 14 is provided on the upper surface of the first connecting block 13; the top end of the first spring 14 is fixedly connected to the inside of the second water pipe 6, and a first locking tooth 15 is fixedly connected to the lower surface of the sliding arm 12; the outer wall of the first locking tooth 15 is provided inside the first water pipe 1, and a second spring 16 is provided on the outer wall of the sliding arm 12; one end of the second spring 16 is connected to the inside of the second water pipe 6.

[0030] Specifically, pulling the second control ring 10 causes the second connecting rod 11 to slide inside the second water pipe 6. This causes the second connecting rod 11 to slide the sliding arm 12 against the outer wall of the first connecting block 13. The sliding arm 12 then pushes the second spring 16 to retract. Further, the sliding arm 12 causes the first locking tooth 15 to slide into the second water pipe 6, pushing the first water pipe 1 into the second water pipe 6. Releasing the second control ring 10 releases the elastic force of the second spring 16, causing the second spring 16 to push the sliding arm 12 to slide. The sliding arm 12 then pushes the first locking tooth 15 to retract. The first water pipe 1 is pushed to the outer wall of the first water pipe 1, and the first water pipe 1 pushes the first locking tooth 15 to slide. The first locking tooth 15 pushes the sliding arm 12 and the first connecting block 13 to slide. The first connecting block 13 pushes the first spring 14 to retract. When the first water pipe 1 is rotated to the positioning position, the first spring 14 releases its elastic force to push the sliding arm 12 and the first connecting block 13 to slide. The sliding arm 12 pushes the first locking tooth 15 into the first water pipe 1, thereby achieving the effects of rapid response and positioning of the leak point, automatic alignment in complex spaces, and adaptive fitting of pipe diameter deformation.

[0031] Working principle: When using this device, the sliding second control ring 10 drives the second connecting rod 11 to slide inside the second water pipe 6, thereby the second connecting rod 11 drives the sliding arm 12 to slide inside the second water pipe 6, and then the sliding arm 12 drives the first locking tooth 15 to slide inside the second water pipe 6. Further, the sliding arm 12 pushes the second spring 16 to contract, thereby the sliding arm 12 pushes the first connecting block 13 to slide, and then the first connecting block 13 pushes the first spring 14 to contract, further pushing the first water pipe 1 into the second water pipe 6. Then, the second control ring 10 is released to release the elastic force of the second spring 16, thereby the second spring 16 pushes the sliding arm 12 to slide on the outer wall of the first connecting block 13, and then the sliding arm 12 drives the first locking tooth 15 to slide, thereby the first spring 14 releases the elastic force to push the first connecting block 13 to slide, and then the first connecting block 13 pushes the sliding arm 12 and the first locking tooth 15 to slide into the first water pipe 1, thereby achieving the effects of rapid response and positioning of the leak point, automatic alignment in complex spaces, and adaptive fitting of pipe diameter deformation.

[0032] The first control ring 4 is then pushed to drive the second locking tooth 7 to slide, thereby pushing the third spring 8 to contract and release the fixation on the ring 902, thus achieving the effect of self-locking the iris component 9. Then, the first control ring 4 is rotated to drive the second locking tooth 7 to slide inside the first dust cover 3. The second locking tooth 7 further drives the third spring 8 and the second connecting block 901 to rotate, thereby driving the ring 902 to rotate. The ring 902 then drives the first connecting rod 903 to rotate, and the first connecting rod 903 further drives the blade 904 to slide on the outer wall of the first dust cover 3, thereby achieving the effects of pipe diameter adaptive sealing, impact resistance and stability, and rapid reduction of leak-stopping response time.
