Description

Technical Field

[0001] This utility model relates to the field of marine semi-submersible vessel technology, specifically a marine semi-submersible vessel with multi-airbag collaborative trim. Background Technology

[0002] Offshore semi-submersible vessels, also known as semi-submersible mother ships, submerge their cargo decks by adjusting their ballast water levels. This allows specific cargoes (such as barges, yachts, ships, and drilling platforms) to be transported from a designated location onto the cargo deck and then delivered to the designated location.

[0003] Offshore semi-submersible vessels are generally equipped with airbags, which can increase the stability of the vessel during submersion and reduce swaying and vibration. However, in the existing technology, the airbags installed on offshore semi-submersible vessels are generally exposed on the outside, and the protective effect of the airbags is generally limited. When the vessel is hit by an object during submersion, it is easy to be damaged and leak air. Therefore, a multi-airbag coordinated trim offshore semi-submersible vessel is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-airbag synergistic trim marine semi-submersible vessel, which has advantages such as improved protective performance of the outer side of the airbags. It solves the problem that the airbags installed on existing marine semi-submersible vessels are generally exposed on the outside, and the protective performance of the airbags is generally poor. When the airbags are hit by objects during the descent, they are prone to damage and air leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A semi-submersible marine vessel with multi-airbag coordinated trim includes a semi-submersible vessel body. Several first airbags are fixed to the front and rear sides of the left side of the upper surface of the semi-submersible vessel body by large cylindrical brackets. Second airbags are fixed to the front and rear sides of the upper surface of the semi-submersible vessel body by fixed chains. An anti-detachment mechanism is provided on one side of the semi-submersible vessel body.

[0007] The anti-detachment mechanism includes two fixed frames fixed to one side of the semi-submersible vessel body. The top walls of the inner cavities of the fixed frames on both the front and rear sides are hinged to electric push rods via hinge seats. The outer sides of the output ends of the electric push rods on both the front and rear sides are hinged to fixed plates via hinge seats. A protective frame is fixed to the lower surface of the fixed plate. The opposite sides of the fixed plates on both the front and rear sides are hinged to one side of the semi-submersible vessel body via hinge seats.

[0008] Furthermore, connecting frames are fixed on both the front and rear sides of the upper surface of the semi-submersible vessel body, and the connecting frames on both the front and rear sides are located on the opposite side of the second airbags on the front and rear sides.

[0009] Furthermore, limit frames are fixed on both the front and rear sides of the upper surface of the semi-submersible vessel body, and the limit frames on both the front and rear sides are located on the opposite side of the second airbags on the front and rear sides.

[0010] Furthermore, the anti-detachment mechanism also includes telescopic rods that are hinged to the left and right sides of the upper surface of the front and rear fixed plates via hinge seats. The end of the telescopic rod away from the fixed plate is hinged to one side of the semi-submersible vessel body via a hinge seat.

[0011] Furthermore, the telescopic rod includes a first slide rod, and a second slide rod is slidably connected to the outer side of the first slide rod.

[0012] Furthermore, the telescopic rods on the left and right sides are symmetrically distributed on the left and right sides of the longitudinal central axis of the fixed plate.

[0013] Furthermore, the second airbags are symmetrically distributed on both the front and rear sides of the transverse centerline of the semi-submersible vessel.

[0014] Furthermore, the fixing plate is made of stainless steel, and the protective frame is made of stainless steel.

[0015] Compared with the prior art, this utility model provides a semi-submersible marine vessel with multi-airbag collaborative trim, which has the following beneficial effects:

[0016] This multi-airbag synergistic trim semi-submersible vessel enhances stability during descent and reduces swaying and vibration through the buoyancy of several first airbags on the fore and aft sides. Two second airbags, fixed to both sides of the semi-submersible vessel, further enhance lateral stability and ensure balance during descent. The combination of fixing plates and protective frames improves the external protection of the first airbags on the fore and aft sides, reducing impacts from external objects on the airbags during descent.

The second airbags 3 on both the front and rear sides are symmetrically distributed on the front and rear sides of the transverse central axis of the semi-submersible vessel body 1.

[0025] It should be noted that the connecting frames 5 on the front and rear sides and the limiting frames 6 on the front and rear sides can improve the protective performance and the stability of the second airbags 3 on the front and rear sides. By adding several first airbags 2 and two second airbags 3 to the semi-submersible vessel body 1, the stability of the semi-submersible vessel body 1 when it dives can be increased.

[0026] Please see Figures 3 to 4 In this embodiment, the anti-detachment mechanism 4 includes two fixed frames 401 fixed to one side of the semi-submersible vessel body 1. The top walls of the inner cavities of the front and rear fixed frames 401 are hinged to electric push rods 402 through hinge seats. The outer sides of the output ends of the front and rear electric push rods 402 are hinged to fixed plates 403 through hinge seats. The lower surface of the fixed plates 403 is fixed with a protective frame 404. The opposite sides of the front and rear fixed plates 403 are hinged to one side of the semi-submersible vessel body 1 through hinge seats.

[0027] Specifically, by setting a fixing plate 403 and a protective frame 404 on the upper side of several first airbags 2 on the front and rear sides, the stability of the several first airbags 2 on the front and rear sides during descent can be improved, the protective performance of the outer side of the several first airbags 2 on the front and rear sides can be improved, and the impact of external objects can be reduced. The first airbags 2 and the second airbags 3 are made of high-strength rubber or composite materials to improve the durability and reliability of the airbags. The surface of the airbags can be coated with a protective layer to prevent seawater corrosion and ultraviolet aging. The airbags are inflatable airbags, and an inflation head is set on one side of the airbag.

[0028] Specifically, the anti-detachment mechanism 4 also includes telescopic rods 405 that are hinged to the left and right sides of the upper surface of the front and rear fixed plates 403 via hinge seats.
