[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] An embodiment of the present invention:

[0032] like Figure 1-4 As shown, the underwater wave-absorbing cabin device of the offshore floating platform for precision marine equipment includes an outer wave-absorbing cabin 1, an inner wave-absorbing cabin 2, and a connecting structure 3;

[0033] The outer chamber 1 of the wave-absorbing chamber comprises an outer wave-absorbing chamber 11, an inner wave-absorbing plate 12 and a first welding joint 13;

[0034] The inner chamber 2 of the wave-breaking chamber includes an inner chamber side wall 21, an inner chamber bottom plate 22, an inner chamber top plate 23, a circular pipe connection port 24 and a second welding connection port 25;

[0035] The connection structure 3 includes an upper connection fixing structure 31 , a wave-breaking chamber outer compartment connection chain 32 , a wave-breaking chamber inner compartment pipeline protection pipe 33 and a wave-breaking chamber inner compartment connection chain 34 .

[0036] The inner chamber 2 of the wave-absorbing cabin is arranged inside the outer chamber 1 of the wave-absorbing cabin; the connecting structure 3 is fixedly connected to the bottom wall of the offshore floating platform through the upper connecting fixing structure 31.

[0037] The outer wave-breaking chamber 11 is a steel box structure with a hollow interior and an open top. The box is made of thickened steel plates, and vertically arranged elliptical hole structures are distributed on the four sides. The elliptical holes have smooth streamlines, which reduces the turbulence and local water pressure of the water flow in the holes, thereby reducing the damage of the water flow to the wave-breaking plate. The bottom plate is a complete steel plate to ensure that no seawater enters or exits the bottom.

[0038] The inner wave-breaking plate 12 includes four steel structures, which are fixed in directions parallel to the four sides of the outer wave-breaking chamber 11 and form a cavity with the side walls of the outer wave-breaking chamber 11. The holes on the inner wave-breaking plate 12 are elliptical holes arranged horizontally, and the holes on the inner wave-breaking plate 12 are staggered and do not overlap with the holes on the outer wave-breaking chamber 11, so as to avoid the formation of water flow in the overlapping part, resulting in obvious water flow force in the overlapping part. The holes on the outer wave-breaking chamber 11 and the inner wave-breaking plate 12 cooperate with each other to cause wave breaking when the seawater passes through the outer cabin 1 of the wave-breaking chamber, thereby achieving the first layer of wave-breaking effect and resisting the impact of a large amount of wave force and water flow force on the internal equipment of the inner chamber 2 of the wave-breaking chamber.

[0039] The first welding connection ports 13 are located on the outer bulkheads on both sides of the outer wave-absorbing chamber 11 and are connected to the outer wave-absorbing chamber 11 by welding, thereby increasing the contact area with the connection structure 3 and ensuring the connection strength.

[0040] The inner chamber side wall 21 is a steel welded structure;

[0041] The inner chamber bottom plate 22 is a steel hollow structure. The holes on the inner chamber bottom plate 22 are parallel to each other in a square structure. Seawater can enter and exit the inner chamber 2 of the wave-breaking chamber through the hole structure, thereby eliminating part of the sloshing of seawater in the chamber and at the same time being able to bear the weight of the precision marine equipment inside. The bottom plate is connected to the inner chamber side wall 21 by welding. The bottom hollow structure of the inner chamber bottom plate 22 reduces the damage to the structure of the precision marine equipment caused by the impact force generated by the sloshing of seawater in the wave-breaking chamber 2, playing a second layer of wave-breaking role, thereby achieving the safe placement of precision marine equipment under the floating platform.

[0042] The inner chamber top plate 23 is a steel structure, connected to the inner chamber side wall 21 by welding on all sides, and three circular pipe connection ports 24 are provided on the inner chamber top plate 23;

[0043] The circular pipe connection port 24 is edge-wrapped with anti-corrosion silicone material to reduce wear of the pipe therein;

[0044] The second welding connection ports 25 are located on the outer bulkheads on both sides of the inner chamber sidewall 21 and are connected to the inner chamber sidewall 21 by welding, thereby increasing the contact area with the connection structure 3 and ensuring the connection strength.

[0045] The outer cabin connection chain 32 of the wave-absorbing cabin is a hinge structure, the upper end of the hinge is welded to the upper connection fixing structure 31, and the lower end is welded to the first welding connection port 13;

[0046] The connecting chain 34 of the inner chamber of the wave-breaking chamber is a hinge structure, the upper end of the hinge is welded to the upper connecting and fixing structure 31, and the lower end is welded to the second welding connection 25;

[0047] The upper end of the pipe protection pipe 33 in the wave-breaking chamber is connected to the upper connecting and fixing structure 31 by bolts, and the lower end is connected to the circular pipe connection port 24 by bolts.

[0048] The pipeline required for connecting the equipment to the offshore floating platform passes through the circular pipe connection port 24 and is connected to the offshore floating platform through the pipe protection pipe 33 in the wave-breaking chamber.

[0049] The wave-breaking chamber inner pipe protection pipe 33 is made entirely of flexible anti-corrosion plastic material.

[0050] First, weld the inner chamber side wall 21 to the inner chamber bottom plate 22; then weld the upper end of the wave-breaking chamber connecting chain 34 to the upper connecting and fixing structure 31, and weld the lower end to the second welding connection port 25; then fix the four steel structures of the inner wave-breaking plate 12 parallel to the four sides of the outer wave-breaking chamber 11, and then weld the upper end of the wave-breaking chamber connecting chain 32 to the upper connecting and fixing structure 31, and weld the lower end to the first welding connection port 13; then weld the upper end of the wave-breaking chamber inner chamber pipe protection pipe 33 to the upper The upper connecting and fixing structure 31 is connected by bolts, and the lower end is connected to the circular pipe connecting port 24 by bolts; then the precision marine equipment that can directly contact seawater is placed in the inner chamber 2 of the wave-breaking chamber, and the pipelines required for the equipment to connect with the floating marine platform are passed through the circular pipe connecting port 24, and connected to the floating marine platform through the inner chamber pipe protection pipe 33 of the wave-breaking chamber; finally, the inner chamber top plate 23 is welded to the inner chamber side wall 21 on all sides, and the upper connecting and fixing structure 31 is fixedly connected to the offshore floating platform.

[0051] The utility model is arranged as a whole under the offshore floating platform, which effectively increases the space utilization rate of the offshore floating platform, reduces the demand for the floor space of the offshore floating platform, and reduces the related costs; at the same time, the two-layer wave-breaking device effectively reduces the impact of waves in the marine environment, and reduces the damage to the structure of precision marine equipment caused by the impact force generated by the swaying of seawater in the wave-breaking cabin 2, thereby ensuring that the precision marine equipment can be safely placed underwater.
