The offshore floating structure is subjected to wave loads, both in shallow and deep sea. In order to absorb and consume wave energy and thereby reduce wave forces, and to ensure safety of the offshore floating structure and personnel on the offshore floating structure, a floating breakwater is typically deployed around the floating structure. The floating breakwater consists of a box body or a floating row with a certain draft, one end of the box body and the floating row are connected with the upper end of an anchor chain, and the lower end of the anchor chain is meshed into the seabed soil through an anchor to stabilize the floating breakwater so as to enable the floating breakwater to float on the water surface. The box bodies or the floating rows are connected through the connecting device, and the structural form of the connecting device has important influence on the motion performance, the wave eliminating performance and the safety performance of the whole structure of the floating breakwater. .

The rigid connection mode has the following defects: the shear force generated by the undulating waves on the connecting cylinders seriously affects the strength of the connecting cylinders, and the whole floating breakwater fails due to the fact that the connecting cylinders are sheared off over time.

The invention aims to provide a connecting device for a floating breakwater, which is connected with a box body or a floating row of the floating breakwater, so that wave energy is absorbed and consumed, the wave force born by the floating breakwater is reduced, and the safety of the floating breakwater is improved.
The aim of the invention can be achieved by the following technical scheme:
the connecting device of the floating breakwater comprises a rubber block and a plurality of flexible connecting mechanisms, wherein the rubber block is in a strip shape, and two ends of the rubber block are respectively connected with the corresponding floating breakwater ends through the flexible connecting mechanisms; the inner skeleton steel pipes are respectively transversely arranged in the two ends of the rubber block, the ends of the inner skeleton steel pipes respectively extend out of the outer side face of the rubber block, one end of the flexible connecting mechanism is respectively connected with the ends of the inner skeleton steel pipes, and the other end of the flexible connecting mechanism is connected with the floating breakwater.
The object of the present invention can be further achieved by the following technical means.
Further, the inner skeleton steel tube is in a cross shape which is vertically intersected, cross-shaped ends respectively cross the longitudinal side surfaces corresponding to the rubber blocks, and one ends of the flexible connecting mechanisms are respectively connected with the cross-shaped ends.
Further, the flexible connecting mechanism comprises a sealing plate, lifting lugs, shackles and chains, the sealing plate is fixed on the end of a cross-shaped skeleton steel pipe, the lifting lugs are vertically fixed on the sealing plate, one end of each chain is hinged with each lifting lug through the shackles, and the other end of each chain is connected with a corresponding semicircular ring on the floating breakwater through the shackles.
Further, a rectangular vulcanization hole traversing the rubber block is formed in the longitudinal center of the rubber block. The longitudinal edges of the rectangular vulcanization holes are consistent with the longitudinal direction of the rubber blocks, and the two ends of the longitudinal edges of the rectangular vulcanization holes are respectively extended to form a cutting seam which is cut into the rubber blocks, so that a rubber pad with one edge connected with the rubber blocks is formed. The apex angle of rubber pad is the fillet, the end of joint cutting is equipped with the through-hole that traverses the rubber piece.
The invention has simple structure and convenient use, and greatly reduces the manufacturing cost. The two ends of the rubber block are respectively connected with the corresponding box bodies or the floating bars of the floating breakwater through the flexible connecting mechanisms, so that the floating breakwater is formed by connecting the box bodies or the floating bars, the wave force is greatly reduced, and the longitudinal impact of the connecting structure is reduced. The rubber block can meet the impact between floating body structures at two ends and prevent corrosion. The vulcanized rubber block can increase the strength, elasticity and wear resistance of the rubber, and the vulcanization holes enable the rubber block to be vulcanized fully, so that the structural rigidity is reduced while the structural quality of the rubber is ensured. The rubber pads arranged on the two sides of the vulcanizing hole can avoid instability of the rubber block under the condition of ballast load, and the rubber pads with the round corners can avoid shearing with the rubber block when the rubber block is subjected to complex load, so that the service life of the rubber block is prolonged.
