Its core features are its stability and shallow draft, making it suitable for marine engineering transportation and installation operations. In terms of specific applications, the current semi-submersible barge is mentioned in the patent publication number "CN202400258U". In order to improve the stability of the semi-submersible barge, the semi-submersible barge and the pontoon are tightly connected to form a device to improve the stability of the semi-submersible barge.

[0003] Specifically, the structure of the device for improving the stability of the semi-submersible barge by fastening the semi-submersible barge and the pontoon is that the semi-submersible barge and the pontoon are fastened together by fasteners to form the device for improving the stability of the semi-submersible barge, that is, the adjacent semi-submersible barge and the pontoon are fastened together by fasteners. At present, during the fastening of the semi-submersible barge and the pontoon, a gap will be formed between the semi-submersible barge and the pontoon at the fastening connection.

The connecting strip 30 is connected to a connecting piece three 31. A force-applying inclined wall is provided on the connecting piece three 31. The top of the control rod 29 is flush with the top of the connecting piece three 31.

[0038] The rotating sleeve one 27 drives the connecting strip 30 and the connecting piece three 31 to rotate. The rotating sleeve two 21 drives the control rod 29 to rotate. When the control rod 29 rotates to the position of the connecting piece three 31, the protruding head one 292 of the control rod 29 is in contact with the force-applying inclined wall of the connecting piece three 31. At this time, the tension spring 34 is compressed, and the protruding head one 292, the protruding head two 10 and the operating rod 403 move towards the direction close to the rotating sleeve one 27, and the protruding head two 10 penetrates into the rotating sleeve one 27.

Next, the cable is drawn out. The worker screws the rotating bar onto the first interface 25 and the second interface 24; the worker firmly holds the second rotating sleeve 21 with the palm, and rotates the rotating bar. After the rotating bar is connected to the second rotating sleeve 21 and then penetrates into the connection between the first interface 25 and the second interface 24 (thus achieving the first tight connection), the worker releases the second rotating sleeve 21 and continues to rotate the rotating bar. The rotating bar and the second rotating sleeve 21 rotate together. One end of the rotating bar penetrates out of the first interface 25 and the second interface 24. Synchronously, the second rotating sleeve 21 drives the control rod 29 to apply force on the first rotating sleeve 27, so that the first rotating sleeve 27 drives the connecting bar 30 and the third connecting piece 31 to rotate together.

5. The fastening device for a semi-submersible barge and a floating box according to claim 4, characterized in that, The rotating sleeve 2 (21) is provided with an annular columnar port 1 (28). The annular columnar port 1 (28) is flush with the inner top of the rotating sleeve 1 (27). The bottom of the annular columnar port 1 (28) is connected to an annular columnar port 2 (33). The annular columnar port 2 (33) is connected to the rotating sleeve 2 (21). A control rod (29) is provided in the annular columnar port 1 (28). The control rod includes a protruding head 1 (292), a protruding head 2 (10) and an operating rod (403); a bearing bar (22) is provided in the annular columnar port 1 (28). The operating rod (403) penetrates through the bearing bar (22). A tension spring (34) is provided between the bearing bar (22) and the protruding head 1 (292).

6. The fastening device for a semi-submersible barge and a floating box according to claim 5, characterized in that, The rotating sleeve 1 (27) is provided with a connecting bar (30). The connecting bar (30) is connected to the connecting piece 3 (31). The connecting piece 3 (31) is provided with a force-applying inclined wall.

7. The fastening device for a semi-submersible barge and a floating box according to claim 6, characterized in that, A cable is passed through the connecting port 1 (25) and the connecting port 2 (24). After connecting the cable, pull the two ends of the cable to make the connecting piece 1 (5) of the semi-submersible barge (2) penetrate between a pair of connecting pieces 2 (4) of the floating box (3), and the connecting port 1 (25) and the connecting port 2 (24) communicate with each other; Then, pull out the cable. The worker screws the rotating bar onto the connecting port 1 (25) and the connecting port 2 (24); the worker fixes the rotating sleeve 2 (21), and rotates the rotating bar. After the rotating bar is connected to the rotating sleeve 2 (21) and the rotating bar penetrates into the connection between the connecting port 1 (25) and the connecting port 2 (24), the worker releases the rotating sleeve 2 (21), and continues to rotate the rotating bar. The rotating bar and the rotating sleeve 2 (21) rotate together. One end of the rotating bar penetrates through the connecting port 1 (25) and the connecting port 2 (24). Synchronously, the rotating sleeve 2 (21) drives the control rod (29) to apply force on the rotating sleeve 1 (27), so that the rotating sleeve 1 (27) drives the connecting bar (30) and the connecting piece 3 (31) to rotate together, and the connecting piece 3 (31) penetrates into the connecting part 2 (26).
