Description

Technical Field

[0001] The invention belongs to the technical field of floating breakwaters, and in particular relates to a connection system between a flexible curtain and a floating body. Background Art

[0002] Traditional bottom-mounted rigid breakwaters have problems such as high construction costs, easy environmental pollution, and difficult repair after damage, and their application is limited in deep water conditions. Therefore, the existing technology has developed a floating breakwater solution. Some breakwaters are equipped with flexible curtains at the bottom to disrupt the movement trajectory of water particles, while converting wave energy into its own flexible movement, further improving the protection and wave elimination effects. However, the connection method between the existing flexible curtain and the upper floating breakwater is relatively simple. In deep-sea engineering, since the length of the flexible curtain can reach tens of meters or even hundreds of meters, the deadweight and hydrodynamic loads are large, so the connection node between the floating body and the curtain needs to withstand a high tensile force, and the curtain is easy to break at the connection. In addition, the curtain stress level around the connection node area is high and the stress fluctuation is significant. Its fatigue life is relatively reduced compared to the bottom, and it is also easy to be damaged in extreme environments. Therefore, it is necessary to improve the connection structure between the existing flexible curtain and the offshore floating body. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] A connection system between a flexible curtain and a floating body, such as Figures 1 to 6 As shown, it includes an auxiliary connector 2 arranged on the top of the flexible curtain 1, and the auxiliary connector includes a constraint steel plate 3 symmetrically arranged on both sides of the flexible curtain. A variable cross-section part is provided on the upper part of the auxiliary connector. Specifically, in the variable cross-section part, a plurality of semicircular floating seats 4 are arranged at intervals above the two constraint steel plates along the length direction of the flexible curtain. At the same time, the positions above the two constraint steel plates where the floating seats are not arranged are closed by the top plate 23; the floating seat and the upper protective shell are supported by a column 21, and the lower end of the column is a matching structure that rotates with the inner surface of the floating seat. As an example, the matching structure is a semi-cylindrical structure, the axial direction of which is consistent with the length direction of the floating body, and its arc surface matches the arc groove on the upper surface of the floating seat, so that the floating seat swings left and right relative to the floating body.

[0031] The two ends of the floating seat are connected to the protective shell 6 through vertical buffer components 5, and oblique buffer components 7 are respectively provided between the two sides of the floating seat and the protective shell. It should be noted that the length of the connection system provided by the invention is the same as the length of the floating body. If the length of the floating body is longer, multiple connection systems a are set along the length direction of the floating body. The protective shell is hollow inside, and a long hole is opened at its bottom along the length direction of the curtain, so that two curved arms 8 are formed at the bottom of the protective shell, and horizontal buffer components 9 are installed on the curved arms.

[0032] Two oblique buffer components are arranged on both sides of the connecting buffer mechanism. The oblique buffer components include an elastomer 10 and a connector 11. The elastomer is formed by stacking and vulcanizing multiple layers of rubber and thin steel plates in sequence, and the upper side of the elastomer is directly vulcanized on the floating seat. The oblique buffer component is used not only to buffer the swing of the floating seat, but also to support the floating seat, that is, the elastomer can also play a pressure-bearing role. As an example, the elastomer can adopt the riser flexible joint in the prior art. The swing center of the elastomer is consistent with the swing center of the floating seat. The connector is fixed to the side wall of the protective shell by the side connector 12.

[0033] The transverse buffer assembly includes a rubber column 14 installed on the curved arm through a transverse connector 13. The float is positioned by a mooring cable 31. When the flexible curtain swings relative to the float 22, the restraining steel plate of the auxiliary connector will touch the transverse buffer assembly. At this time, the rubber column can play an anti-collision and limiting role. As an example, the rubber column can be made of pure rubber material, or it can be made by stacking and vulcanizing multiple layers of rubber and thin steel plates in sequence. A connection buffer mechanism is provided between the two restraining steel plates. Specifically, the connection buffer mechanism includes several layers of functional plates 15 with different heights, and each functional plate is provided with a number of buffer holes 16.

[0034] A stiffening plate 24 is provided between the restraining steel plate and the floating seat. In an optional embodiment, after the floating seat, the restraining steel plate and the functional plate are formed into a whole, rubber is poured into the buffer cavity from the bottom of the restraining steel plate (i.e., the buffer hole on the functional plate of the lowest layer). The rubber in the uppermost buffer cavity is connected to the floating seat by bolts, and the rubber at the bottom of the restraining steel plate is fixed to the lower flexible curtain by bonding or vulcanization. Such a structural design connects the rubber in each buffer cavity with the buffer hole on each functional plate, so that each functional plate and the rubber become a whole, effectively strengthening the overall tensile bearing capacity between the floating seat and the connecting buffer mechanism.

[0035] A buffer cavity 17 is formed between every two adjacent functional panels, and the buffer holes on the two adjacent functional panels are arranged in a staggered manner. In the vertical direction, the flexible curtain and the float are supported by the vertical buffer assembly and the connecting buffer mechanism, and the buffering effect is effectively exerted, thereby improving the structural stability between the flexible curtain and the float. The protective shell and the auxiliary connector, as well as the protective shell and the flexible curtain, are connected by a suspension connector 20. Specifically, an upper suspension end 18 is provided at the lower part of each bent arm, and a lower suspension end 19 is provided at the lower end of each constraining steel plate. The upper suspension end and the lower suspension end are fixed by a suspension connector, and the lower suspension end and the curtain suspension end on the curtain are fixed by a suspension connector. The bottom of the two constraining steel plates are provided with an outward-turned arc structure to prevent the flexible curtain from contacting the bottom of the constraining steel plate and being worn during bending and swinging.

[0036] As an example, the suspension connection includes a cable, and the curtain suspension end is arranged at the lower part of the flexible curtain. The flexible curtain is connected to the constraining steel plate and the protective shell at the same time through the cable, so as to ensure that even if the flexible curtain is partially damaged, the necessary pulling force can be provided to the flexible curtain to prevent the cracks from continuing to open and causing the flexible curtain to break as a whole and sink to the seabed. Therefore, the basic configuration of the flexible curtain is still maintained, which is convenient for later repair.

[0037] In an optional embodiment, the vertical buffer assembly includes a vertically arranged bellows 26, with end plates 27 provided at the top and bottom of the bellows, and the end plates are welded and fixed to the bellows, so that a closed space is formed inside the bellows by using the two end plates. The end plate at the top of the bellows is fixed to the top plate of the protective shell by the top connecting bolts 28, and the end plate at the bottom of the bellows is fixed to the floating seat 25 by the lower connecting bolts 29.

[0038] At the same time, a buffer spring 30 is provided in the bellows, the upper end of which is fixed to the end plate at the top of the bellows, and the lower end of which is fixed to the end plate at the bottom of the bellows. Preferably, the two vertical buffer components are arranged symmetrically with the connecting buffer mechanism as the center. When the floating seat rotates, one side of the spring is stretched and the other side is compressed, forming a torque opposite to the rotation direction, providing elastic rotation constraints for the floating seat. The bellows can stretch or contract when the floating seat rotates, and at the same time ensure that the spring is in a closed space to prevent the spring from rusting and failing.

[0039] Usually, the functional panels are provided with 3-10 layers. The functional panels are arranged horizontally. The top of the restraining steel plate is welded and fixed to the lower surface of the floating seat. The floating seat is cut from a cylindrical steel pipe. The transverse connector includes a horizontally arranged screw rod. The side connector includes a horizontally arranged screw rod.

[0040] The connection system between the flexible curtain and the floating body provided by the invention has high tensile bearing capacity and allows a certain rotation of the top of the curtain. It can withstand the deadweight and hydrodynamic load of the flexible curtain and elastically constrain the flexible rotation of the curtain. The top of the flexible curtain is strengthened by symmetrically arranged constraint steel plates to avoid breakage of the top of the curtain due to stress concentration or cyclic load. The flexible curtain is connected to the constraint steel plate and the protective shell by cables to avoid through-type tearing at different positions of the flexible curtain, thereby forming multi-level safety protection.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
