[0027] As shown in Figures 1-4 The present application provides a marine water bag type plugging device, which comprises a double-rotation screw 1, a first sliding sleeve assembly 2, a second sliding sleeve assembly 3, a fourth support assembly 4, a bag body support assembly 5 and a bag body 59.

[0028] The double-rotation screw 1 is a hollow tubular screw, which is provided with a right-threaded segment 11 and a left-threaded segment 12. The right-threaded segment 11 is located in the front half, and the left-threaded segment 12 is located in the rear half. Both of them are provided with external threads in opposite directions. A water injection hole 13 is provided on the pipe body of the right-threaded segment 11, and a plug 14 is provided behind the water injection hole 13. The plug 14 is used to block the water flow so that it does not flow in the horizontal direction. The end of the left-threaded segment 12 is coaxially provided with a square segment 15 and a cylindrical threaded segment 16 in sequence. The square segment 15 is a square column, and the cylindrical threaded segment 16 is a cylinder with threads on the outer surface. A sleeve 17 is sleeved on the outside of the square segment 15, and a nut 19 is provided with internal threads matched with the threads of the cylindrical threaded segment 16 to lock the sleeve 17. A plurality of handles 18 (4 in the figure) are circumferentially provided on the sleeve 17.

[0029] The first sliding sleeve assembly 2 comprises a first sliding sleeve 21, a first threaded sleeve 22 and a first bolt 23. The diameter of the first sliding sleeve 21 is slightly larger than that of the right-threaded segment 11, and it is sleeved on the right-threaded segment 11. The internal threads of the first threaded sleeve 22 are matched with the external threads of the right-threaded segment 11, and the first sliding sleeve 21 is connected and sealed with the first threaded sleeve 22 through the first bolt 23 (multiple groups, uniformly distributed). The second sliding sleeve assembly 3 comprises a second sliding sleeve 31, a second threaded sleeve 32, a gripping handle 33 and a second bolt 34. The diameter of the second sliding sleeve 31 is slightly larger than that of the left-threaded segment 12, and it is sleeved on the left-threaded segment 12. The internal threads of the second threaded sleeve 32 are matched with the external threads of the left-threaded segment 11, and a plurality of gripping handles 33 (multiple groups, 4 groups in the figure) are circumferentially provided on the second threaded sleeve 32. The second sliding sleeve 31 is connected and sealed with the second threaded sleeve 32 through the second bolt 34 (multiple groups, uniformly distributed). The first threaded sleeve 22 and the second threaded sleeve 32 are used for the movement cooperation of the bag body support assembly 5 and the double-rotation screw 1, and the first sliding sleeve 21 and the second sliding sleeve 31 are convenient for sealed connection with the bag body 59.

[0030] The capsule support assembly 5 is used for supporting the capsule 59 in the state of being supported, and comprises a first support 51, a second support 52, a third support 54, a front hinge 55, a left hinge 56, a right hinge 57 and a rear hinge 58. The first support 51 is a column (a plurality of groups, 8 groups in the figure), the second support 52 is a U-shaped column (a plurality of groups, 8 groups in the figure) and is provided with a sleeve hole 53, and the third support 54 is a column (a plurality of groups, 8 groups in the figure). The first support 51 is rotationally connected with the first sliding sleeve 21 through the front hinge 55, rotationally connected with the second support 52 through the left hinge 56, the third support 54 is rotationally connected with the second support 52 through the right hinge 57, and rotationally connected with the second sliding sleeve 31 through the rear hinge 58.

[0031] The capsule 59 is a soft rubber capsule, the inside of which is filled with water-absorbing and swelling resin, the middle part of the capsule 59 is concave, the capsule 59 is wrapped around and bonded to the outside of the first support 51, the second support 52, the third support 54, the front hinge 55, the left hinge 56, the right hinge 57 and the rear hinge 58, and the two ends are respectively sealedly connected with the first sliding sleeve 21 and the second sliding sleeve 31 to form a sealed space.

[0032] The fourth support assembly 4 comprises a bearing 41, a fourth support 42 and a bellows 43. The bearing 41 is sleeved and fixed at a position of the middle part of the double-rotational-direction screw 1, and the double-rotational-direction screw 1 can rotate in the bearing 41. The fourth support 42 (a plurality of groups, 8 groups in the figure) is a column, one end of which is fixed to the outer periphery of the bearing 41, and the other end thereof passes through the sleeve hole 53 on the second support 52. The bellows 43 is sleeved outside the fourth support 42, one end of which is connected with the outer periphery of the bearing 41, and the other end thereof is connected with the second support 52 to realize sealing. On the one hand, the fourth support 42 can realize the limiting function when leaking is blocked: the length of the beam of the fourth support 42 corresponding to the outer periphery of the fourth support 42 is greater than the diameter of the broken hole, so that the broken hole can be resisted, and the second support 52 connected with the fourth support 42 is located near the broken hole, which facilitates the cooperation between the second support 52 and the concave part in the middle of the capsule 59 to realize the blocking of the leakage; on the other hand, the stability of the quadrilateral formed by the first support 51, the second support 52, the third support 54 and the double-rotational-direction screw 1 is increased.

[0033] Working principle:

[0034] The water capsule type leaking stoppage device is in the state of being folded before use (as shown in Figure 1 ), at this time, the water injection hole is located inside the capsule, and water flow is filled into the capsule. When the ship leaking stoppage operation is performed, the handle is held, the capsule is stretched into the broken hole, water flow is flowed into the capsule through the water injection hole, the water-absorbing and swelling resin in the capsule absorbs water and swells, at this time, the fourth support resists the broken hole, the handle is held tightly, the handle is rotated clockwise, the first sliding sleeve and the second sliding sleeve are relatively operated, the first support and the third support support the capsule, and the concave part in the middle of the capsule is tightly resisted by the U-shaped second support to realize the leaking stoppage (as shown in Figure 2 ).

[0035] In summary, the device props up the water-absorbing and swelling bag from inside to stop the leakage, without external supporting equipment, and has simple structure. The handle is used to rotate the screw rod to prop up the bag, which is convenient for the user to operate, and thus can effectively reduce the difficulty of the leakage stopping operation. When the external water flow acts on the bag, the bag and the break naturally cooperate to stop the leakage. The concave part of the bag and the U-shaped second support are attached to the break to stop the leakage, which is opposite to the water flow direction, and the greater the water pressure, the tighter the bag is attached to the break after being impacted by the water flow, so it is not easy to loosen. The water in the bag has fluidity, and the break effectively fills the gap between the bag and the break, and strengthens the leakage stopping effect. The device stops the leakage by plugging, without external supporting equipment, and thus can be applied to uneven parts such as the rib part and the corner of the ship body.

[0036] The above is only the preferred embodiment of the present application, and it should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
