Description
Technical Field
[0001] This utility model relates to the technical field of marine leak-sealing devices, specifically a marine rotary box type leak-sealing device. Background Technology
[0002] During navigation, especially in complex sea conditions, ships are prone to collisions, groundings, and other marine accidents due to insufficient crew experience or operational errors. These accidents can lead to hull damage, large amounts of seawater flooding in, and threats to navigational safety. If not handled properly, they can even cause the ship to sink.
[0003] When a ship's hull is breached and floods in, it should use leak-sealing equipment to prevent sinking and prevent leaks. Currently, ships are generally equipped with leak-sealing boxes and other such equipment. Traditional leak-sealing boxes use a covering method to seal leaks from the inside of the hull outwards. During leak-sealing operations, because the direction of the seal is opposite to the direction of water pressure, the water flow impact is significant, making the seal difficult and the operation challenging.

The foldable handle section 43 can be folded and unfolded around the bolt and nut mechanism 44 on the handle fixing section 42.
[0054] This utility model provides a marine rotary box-type leak-sealing device, the working principle of which is as follows: When performing marine leak-sealing operations, the box assembly 1 is in an overlapping state, and the screw 23 and the short pipe 21 are at approximately 90° ( Figure 8 Generally, two people work together. One person holds the U-shaped handle 147 with one hand, and the other person holds the hand ring 27. The two people work together to extend the overlapping box assembly 1 out of the opening, adjust the screw 23 so that it is nearly in a straight line with the short pipe 21, and rotate the hand ring 27 so that the screw 23 drives the box assembly 1 to unfold, forming a sealed box. Figure 7); Untie the strap 310, and the bracket 34 is opened by the spring 38; rotate the locking nut 41 so that the bracket 34 abuts against the damaged inner wall of the hull, and under the support of the bracket 34, the box assembly 1 and the damaged hull are overlapped and sealed. Figure 1 ).
[0055] The leak-sealing device provided in this embodiment of the utility model adopts an integrated structure, which effectively reduces temporary assembly time and workload. On the other hand, it adopts a leak-sealing method from the outside to the inside of the box, and the leak-sealing force is consistent with the water flow impact force, which effectively reduces the difficulty of leak-sealing operation and makes the operation process convenient and quick.
