Technical Field
[0001] This invention belongs to the field of fastening device technology, specifically relating to a fastening device for semi-submersible barges and pontoons. Background Technology
[0002] A semi-submersible barge (also known as a semi-submersible vessel or semi-submersible mother ship) is a special type of vessel that submerges its cargo deck by adjusting its ballast water to carry large floating cargoes (such as drilling platforms, ships, caissons, etc.). Its core characteristics are stability and shallow draft, making it suitable for marine engineering transportation and installation operations.
[0003] In terms of specific applications, as mentioned in the patent publication number "CN202400258U", the semi-submersible barge is fastened to the pontoon to form a device that improves the stability of the semi-submersible barge.
[0004] Specifically, the structure of the device that improves the stability of a 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. In other words, adjacent semi-submersible barges and pontoons are all fastened together by fasteners. Currently, during the fastening process of the semi-submersible barge and the pontoon, gaps are formed between the semi-submersible barge and the pontoon at the fastening point. These gaps are not conducive to the unified structure of the device that improves the stability of the semi-submersible barge by fastening the semi-submersible barge and the pontoon, reducing the semi-submersible barge's torque resistance, anti-breakage and load-bearing capacity, and can also cause cracks when the torsion between the semi-submersible barge and the pontoon is uneven, which is detrimental to the use of the semi-submersible barge. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a fastening device for semi-submersible barges and pontoons. This device effectively avoids the drawbacks of existing technologies where gaps between the semi-submersible barge and pontoons hinder the secure connection between them, resulting in a lack of uniformity in the structure of devices designed to improve the stability of the semi-submersible barge. It also reduces the semi-submersible barge's torque resistance, anti-breakage and load-bearing capacity, and can cause cracks when there is uneven torsion between the semi-submersible barge and pontoons, thus hindering the use of the semi-submersible barge.

The embodiments described in this application are merely some embodiments of this invention, and not all embodiments. Based on the spirit of this invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this invention.
[0034] like Figures 1 to 9As shown, the fastening device for a semi-submersible barge and a pontoon according to the present invention includes:
[0035] The semi-submersible barge and the pontoon are fastened together by fasteners to form a device that improves the stability of the semi-submersible barge. In other words, adjacent semi-submersible barges and pontoons are all fastened together by fasteners.
[0036] The semi-submersible barge and the pontoon are fastened together by fasteners, namely semi-submersible barge 2 and pontoon 3. The side wall of semi-submersible barge 2 is provided with fastener connecting piece 1 5, and the side wall of pontoon 3 is provided with a pair of fastener connecting pieces 2 4.

When the semi-submersible barge 2 and the pontoon 3 are tightly connected, the connecting part 1 1 and the connecting part 2 26 remain flush. To ensure the semi-submersible barge is flush, a receiving opening 9 is provided on each pair of opposite sidewalls of the pair of connecting pieces 2 4, and a receiving opening 7 is provided on each pair of sidewalls of the semi-submersible barge 2. When 2 and pontoon 3 are fastened together, connecting piece 1 5 is located between a pair of connecting pieces 2 4, the top of connecting piece 2 4 is in contact with the semi-submersible barge 2, receiving port 1 9 and receiving port 2 7 are connected, a pair of connecting parts 2 26 are respectively located in a pair of receiving ports 2 7, and connecting part 1 1 is located in receiving port 1 9. When the rotating bar rotates, the rotating bar applies force to connecting part 1, causing connecting piece 3 31 to probe into connecting part 2 26, thus achieving the first and second fastening of the semi-submersible barge 2.

[0042] In a preferred but non-limiting embodiment of the present invention, after the semi-submersible barge 2 and the pontoon 3 are securely connected, water glass is injected into the first 9 and the second 7 of the receiving port to further seal the first 9 and the second 7 of the receiving port, thus forming a unified and fully secure connection.
[0043] In a preferred but non-limiting embodiment of the present invention, the second connecting part 26 and the third connecting piece 31 have the same shape, both being arched sheet structures; one end of the second connecting part 26 is provided with an opening for accommodating the third connecting piece 31; one end and the side wall of the second connecting part 26 are provided with a guide port 6, and a positioning port 8 is provided on the guide port 6; the guide port 6, the positioning port 8, and the opening are all connected; when the first connecting part 1 is inserted into the second connecting part 26, the first protruding head 292 is inserted into the positioning port 8.
[0044] In a preferred but non-limiting embodiment of the present invention, the structure of the connecting part 1 and the connecting part 26 at the receiving port 9 of the connecting piece 24 and the receiving port 7 of the semi-submersible barge 2 is such that when the semi-submersible barge 2 and the pontoon 3 are fastened together, the receiving port 9 and the receiving port 7 are connected.
[0045] In a preferred but non-limiting embodiment of the present invention, the connecting part 1 includes a cylindrical rotating sleeve 27 and a rotating sleeve 21 with the same center line. The rotating sleeve 27 and the rotating sleeve 21 are connected by a rotating roller 32. The rotating sleeve 27 and the rotating sleeve 21 can rotate independently in a ring. The rotating sleeve 27 is a ratchet disc structure. When one end of the operating rod 29 rotates to the inclined wall for applying force, the other end of the operating rod 29 probes into the ratchet teeth of a pair of adjacent ratchet discs of the rotating sleeve 27.
[0046] In a preferred but non-limiting embodiment of the present invention, both the rotating sleeve 27 and the rotating sleeve 21 are provided with columnar through-holes. The through-holes are connected to the connecting port 25 and the connecting port 24, and the center lines of the through-holes, the connecting port 25 and the connecting port 24 are aligned. The inner thread on the inner wall of the through-hole on the rotating sleeve 21 is connected to the outer thread on the outer wall of the rotating strip. The rotating sleeve 21 and the receiving port 9 are connected by the rotating roller 23, and the rotating sleeve 21 can rotate on the receiving port 9.
[0047] In a preferred but non-limiting embodiment of the present invention, the rotating sleeve 21 is provided with an annular cylindrical opening 28, the inner top of the annular cylindrical opening 28 and the rotating sleeve 27 are flush, the bottom of the annular cylindrical opening 28 is connected to an annular cylindrical opening 33, the annular cylindrical opening 33 and the rotating sleeve 21 are connected, the annular cylindrical opening 28 is provided with an operating rod 29, the operating rod 29 includes a protrusion 292, a protrusion 10 and an operating rod 403; the annular cylindrical opening 28 is provided with a support strip 22, the operating rod 403 protrudes through the support strip 22, and a tension spring 34 is provided between the support strip 22 and the protrusion 292.
[0048] In a preferred but non-limiting embodiment of the present invention, the rotating sleeve 27 is provided with a connecting strip 30, the connecting strip 30 is connected to the connecting piece 31, and the connecting piece 31 is provided with a force-applying inclined wall; the top of the operating rod 29 is flush with the top of the connecting piece 31.
[0049] Rotating sleeve 27 drives connecting bar 30 and connecting piece 31 to rotate, rotating sleeve 21 drives operating rod 29 to rotate. When operating rod 29 rotates to connecting piece 31, the protruding head 292 of operating rod 29 and the force applied by connecting piece 31 are pressed together by the inclined wall. At this time, tension spring 34 is compressed, and protruding head 292, protruding head 10 and operating rod 403 move towards the direction of approaching rotating sleeve 27. Protruding head 10 probes into rotating sleeve 27.
[0050] At this time, when the rotating sleeve 21 rotates, the protruding head 210 can drive the rotating sleeve 27 to rotate together. During the rotation, the connecting strip 30 and the connecting piece 31 rotate together. Finally, the connecting piece 31 enters the connecting part 26. During the entry, the connecting strip 30 runs on the guide port 6. When the protruding head 292 reaches the positioning port 8, under the elastic effect of the tension spring 34, the protruding head 292 enters the positioning port 8, performing a tighter fastening connection. When the connecting piece 31 enters the connecting part 26, the connecting strip 30 and the float 3 are arranged side by side, which can further improve the reliability of the fastening connection.
[0051] In a preferred but non-limiting embodiment of the present invention, a connecting cable passes through the first connection port 25 and the second connection port 24. After the connecting cable is connected, pulling the two ends of the cable allows the connecting piece 5 of the semi-submersible barge 2 to penetrate between a pair of connecting pieces 24 of the pontoon 3, and the first connection port 25 and the second connection port 24 are connected.
[0052] Next, the cable is pulled out, and the worker screws the rotating bar onto the connecting port 25 and the connecting port 24. The worker uses his palm to stabilize the rotating sleeve 21 and rotates the rotating bar so that the rotating bar and the rotating sleeve 21 are connected. After the rotating bar enters the connection between the connecting port 25 and the connecting port 24 (thus achieving the first tight connection), the worker releases the rotating sleeve 21 and continues to rotate the rotating bar. The rotating bar and the rotating sleeve 21 rotate together. One end of the rotating bar protrudes from the connecting port 25 and the connecting port 24. Simultaneously, the rotating sleeve 21 drives the operating rod 29 to apply force to the rotating sleeve 27, so that the rotating sleeve 27 drives the connecting bar 30 and the connecting piece 31 to rotate together. The connecting piece 31 enters the connecting part 26 (thus achieving the second tight connection). The first tight connection and the second tight connection are achieved.
[0053] The rotating bar is tightly connected to one end of the connecting port 1 25 and the connecting port 24, which improves the reliability of the connection of the rotating bar. The rotating bar is connected to the connecting port 1 25 and the connecting port 24 through the external thread on the outer wall of the rotating bar and the internal thread on the inner wall of the connecting port 1 25 and the connecting port 24.

During the fastening process, only the rotating bar needs to be operated to simultaneously achieve the initial fastening and subsequent fastening, making operation convenient and the fastening connection function excellent, making it more suitable for long-term use of the semi-submersible barge.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention without departing from the spirit and scope of the present invention. Any modifications or equivalent substitutions should be covered within the protection scope of the claims of the present invention.
