Description

Technical Field

[0001] This utility model relates to the field of ship leak sealing technology, specifically to an airbag-type leak sealing device for ship leakage. Background Technology

[0002] When a ship experiences hull leaks due to collisions, grounding, stranding, or hull corrosion during navigation, emergency plugging measures are necessary to maintain the ship's safety. Water ingress after hull damage threatens the ship's stability and safety. Existing leak-sealing equipment on ships includes wooden plugs, planks, wedges, posts, and hook bolts, which are used to plug leaks from inside the hull. However, these methods require the plugs to be precisely matched to the size of the hole to achieve an effective seal, and they are not effective at sealing small cracks, presenting certain limitations.

[0003] Chinese patent CN 220948450U discloses a leak-sealing device for ships. Depending on the size of the hole, different specifications of threaded columns and filling airbags are selected. The filling airbag with an appropriate expansion volume is selected according to the size of the hole. After the columnar airbag expands, it seals the hole. The sealing structure is held until the sealing rubber ring at the bottom of the cover plate is in close contact with the hull or equipment surface. This device can select an airbag that is compatible with the damaged hole. However, the leak-sealing process needs to be completed quickly. Trying different specifications of airbags and then connecting the sealing structure takes a lot of time.

[0004] Based on this, this utility model proposes an airbag-type leak-sealing device for ship leakage, which can quickly seal leaks while adapting to different types of rupture holes. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides an airbag-type leak-sealing device for ship leakage, thereby solving the aforementioned technical problems.

[0006] An airbag-type leak-sealing device for ship leakage includes a leak-sealing bracket and multiple sizes of filling airbag components. The leak-sealing bracket includes a movable support, a central column rotatably sleeved on the movable support, a top ring connected to the central column via a partition rod, a spring ring hanging on the top ring, and a bottom cover fixedly connected to the bottom of the spring ring. The filling airbag is provided with a connecting post and an air nozzle. The connecting post is inserted into the extension branch seat of the central post. The connecting post is detachably connected to the bottom cover. An adsorption component is rotatably sleeved on the connecting post.

[0007] Furthermore, the bottom cover is provided with symmetrical positioning grooves, and the positioning grooves are connected to positioning blocks through reset springs. The end of the connecting column away from the airbag is provided with a positioning hole that cooperates with the positioning block.

[0008] Furthermore, the adsorption assembly includes a rubber suction cup, a first rod, and a second rod. The rubber suction cup is fixedly connected to the first rod, the first rod is slidably connected to the second rod, and a sleeve ring is fixedly connected to the second rod.

[0009] Furthermore, the first rod body is provided with a sliding cavity, and the second rod body is provided with a screw and a nut, with the screw passing through the sliding cavity and threadedly connected to the nut.

[0010] Furthermore, the central column is slidably connected to a limiting block, and the movable support is provided with a limiting hole that cooperates with the limiting block.

[0011] Furthermore, the central column is provided with a central cavity for placing an air cylinder.

[0012] Due to the adoption of the above technical solution, the beneficial effects of this utility model compared with the prior art include: Multiple sizes of inflatable bladders are connected by spring coils. The size can be quickly tested by rotating the central column and stretching the spring coils. During this process, only replacement is required, and different parts do not need to be connected. After confirmation, the inflatable bladder is inflated, and the positioning block is pressed to make it exit the positioning hole and completely retract into the positioning groove. This allows for quick separation of the bottom cover and the inflatable bladder, thus quickly completing the leak sealing work. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, other implementation methods or equivalent substitutions obtained by those skilled in the art without creative effort are all within the protection scope of the present utility model.

[0015] like Figure 1-4 As shown, an airbag-type leak-sealing device for ship leakage includes a leak-sealing bracket and multiple sizes of filling airbag components 7. The leak-sealing bracket includes a movable support 1, which is equipped with self-locking rollers. A central column 2 is rotatably sleeved on the movable support 1. A top ring 4 is connected to the central column 2 through a partition rod 3. A number of spring rings 5, equal to the number of filling airbag components 7, are hung on the top ring 4. The tops of each spring ring 5 are separated by the partition rod 3, and a bottom cover 6 is fixedly connected to the bottom of the spring ring 5. The filling airbag component 7 is provided with a connecting post 8 and an air nozzle 9. The connecting post 8 is inserted into the extension branch seat 10 of the central post 2. The connecting post 8 is detachably connected to the bottom cover 6. The connecting post 8 is rotatably sleeved with an adsorption component. Rotate the central column 2, select the filling airbag 7 that matches the damaged hole, remove the filling airbag 7 from the extension branch seat 10. Before confirmation, keep the connecting column 8 of the filling airbag 7 connected to the bottom cover 6 to facilitate trying and replacing another filling airbag 7. After confirmation, insert the filling airbag 7 into the damaged hole, inflate it and close the air nozzle 9. Press the positioning block 12 to make it exit the positioning hole 13 and completely retract into the positioning groove 11, which can quickly separate the bottom cover 6 from the filling airbag 7. After the airbag is inflated, the adsorption components are adsorbed and connected to the surrounding hull. The two adsorption components are rotated to adapt to the hull. The sliding cavity 17 of the first rod 15 slides along the screw 18 of the second rod 16, and the rubber suction cup 14 is adsorbed onto the hull by sliding, pressing or pumping air. The wing nut is screwed so that the wing nut abuts against the outer periphery of the sliding cavity 17, so that the first rod 15 and the second rod 16 are kept in a stable state.

[0016] The central column 2 is slidably connected to the limiting block 19, and the movable support 1 is provided with a limiting hole that cooperates with the limiting block 19. Sliding the limiting block 19 downwards so that it enters the limiting hole can prevent the central column 2 from rotating.

[0017] The central column 2 has a central cavity 20, which is used to place an air cylinder, so that the air cylinder can be conveniently carried to inflate the airbag of the filling airbag component 7.
