[0014] The present application has the following beneficial effects due to the above technical solutions:

[0015] 1. The connector structure, four transverse pin shafts, two first bases and two second bases are matched to form a set of suitable breakwater flexible connection device. The set of connector mainly relies on pure mechanical automatic connection, has simple structure, low cost, easy operation, good safety, convenient disassembly and assembly, high maintainability, high reliability, low maintenance cost and does not need too much manual intervention. The connector structure is connected with the first floating body and the second floating body through the pin shaft structure. Four groups of pin shafts and box type connector structure are arranged to bear large shear, bending and torsional load, and meet the connection requirements of the breakwater.

[0016] 2. The engineering implementation requirements of the connector structure are met. Since the breakwater module generally has small width and large length, the design idea of anchor chain is adopted. When the connector body structure adopts an integrated structure, the connector structure can connect the breakwater main module into a section.

[0018] 4. The transverse pin shafts are collinear, so that a certain linear displacement is generated due to rotation, and the pitch and heave degrees of freedom of the floating body can be released.

[0019] 5. The wave breaking and flow resistance performance of the breakwater is ensured. According to the wave breaking principle of the breakwater, the relative degrees of freedom between the breakwater modules are reasonably released to ensure the wave breaking and flow resistance performance of the breakwater. When the connector body structure includes a first connector assembly and a second connector assembly, the relative yaw and sway degrees of freedom are further released, and the relative pitch, relative heave and relative yaw degrees of freedom of the floating structure are released. While ensuring that the wave energy is smoothly converted into the kinetic energy and potential energy of the breakwater main structure, part of the wave can also be reflected back to reduce the environmental load intensity of the breakwater protection area.

[0020] 6、Meanwhile, the connecting device only needs to be provided with a base reinforcing structure by the connected floating body, without reserving space in the design, and the convenience of use is great, and engineering is easy to realize.

[0021] 7、Use is fast and convenient; the structure has a cover locking device, without needing too much manpower intervention in the disassembly and assembly process, and use is convenient and fast. BRIEF DESCRIPTION OF DRAWINGS

[0027] The preferred embodiments of the present application are described below with reference to the accompanying drawings, and are described in detail, so that the functions and characteristics of the present application can be better understood. Figures 1-5

[0028] Please refer to Figures 1-3 The mechanical offshore floating breakwater connecting device according to the embodiment of the present application comprises a connector structure 1, four transverse pin shafts 2, two first bases 3 and two second bases 4. The connector structure 1 comprises a connector body structure 11, and two sides of both ends of the connector body structure 11 are formed with a connecting part 12. Each connecting part 12 is formed with a first pin shaft through hole, and the central axes of the first pin shaft through holes of the two connecting parts 12 on the same side of the connector body structure 11 coincide. The two first bases 3 are fixed to a first floating body 5. The first side of the connector structure 1 is pivotally connected to the corresponding first base 3 through the two transverse pin shafts 2 arranged in the first pin shaft through holes. The second side of the connector structure 1 is detachably pivotally connected to the corresponding second base 4 through the other two transverse pin shafts 2 arranged in the first pin shaft through holes. The second base 4 is fixed to a second floating body 6.

[0029] In the embodiment, the first base 3 comprises two first ear plates 31, and the two connecting parts 12 of the first side of the connector structure 1 are pivotally connected between the two first ear plates 31 through the transverse pin shafts 2.

[0031] The two transverse pin shafts 2 are collinear.

[0032] The connector body structure 11 is rectangular or trapezoidal.

[0033] The mechanical offshore floating breakwater connecting device of the embodiment one of the application can convert the rotation of the coaxial shaft into rotation and linear motion due to the misalignment of the shafts, and the relative motion of the floating body modules can be controlled within a certain range by reasonably designing the misalignment distance at the beginning of the design. Due to the different directions of the shafts, more degrees of freedom of the floating body can be released without increasing the structure greatly, the requirement of the environment load on the connector is reduced, and the engineering purpose is achieved.

[0034] The connecting steps of the mechanical offshore floating breakwater connecting device of the embodiment one of the application are as follows:

[0035] 1) Before the breakwater floating body modules are docked, first, the connecting device is loosened, the cover plate 43 of the second base 4 of the second floating body 6 is opened, and the cover plate 43 is in a state that the transverse pin shaft 2 can enter; 2) in the unconnected state, the connector structure 1 is mainly pulled up at a certain angle by the hinge on the first floating body 5, when the two docking modules gradually approach, the hinge of the first floating body 5 is loosened, and the transverse pin shaft 2 falls into the first pin shaft groove of the second base 4 of the second floating body 6; 3) at the same time, the cover plate 43 falls down instantaneously under the action of the elastic lifting mechanism of the cover plate 43, and is locked by the cover plate 43 locking device relying on its inertia and gravity, thereby completing the connecting step.

[0036] Please refer to Figure 4 and Figure 5The mechanical offshore floating breakwater connecting device of the second embodiment of the present application has the same structure as the first embodiment, and the difference lies in that the connector body structure 11 comprises a first connector assembly 111 and a second connector assembly 112; the two ends of the first side of the first connector assembly 111 form two connecting portions 12, the second side of the first connector assembly 111 is triangular and the middle part forms a connecting groove; the first side of the second connector assembly 112 forms a connecting plate matched with the connecting groove, the connecting plate is triangular, and the two ends of the second side of the second connector assembly 112 form another two connecting portions 12; the connecting plate is partially inserted into the connecting groove and is pivotally connected with the connecting groove through a vertical pin shaft 113 arranged vertically.

[0037] The top of the connecting groove and the connecting plate form at least two locking pin shaft holes matched with each other, and a locking pin 114 is detachably inserted into the locking pin shaft hole.

[0038] The locking pin shaft hole is arranged on the two sides of the vertical pin shaft 113.

[0039] The mechanical offshore floating breakwater connecting device of the second embodiment of the present application releases the relative yawing and surging freedom compared with the first embodiment, and the action relationship is similar to that of the first embodiment. If the locking pin 114 in the connector is inserted, it evolves into the connector of the first embodiment, so the special action is that the locking pin 114 needs to be pulled out before and after the butt joint of the first floating body 5 and the second floating body 6. During the working process of the connector, the locking pin 114 is pulled out, so that the first connector assembly 111 and the second connector assembly 112 can rotate around the vertical pin shaft 113. Similarly, since the first floating body 5 and the second floating body 6 are a certain distance away from the vertical pin shaft 113, a certain linear displacement will be generated by the rotation.

[0040] The mechanical offshore floating breakwater connecting device of the first embodiment and the second embodiment of the present application can be matched and applied. The first embodiment is mainly used for connecting the floating body modules in series to form a group, and the second embodiment is mainly used for connecting the connectors between groups to release the freedom of the spliced floating body. The connecting device of the embodiment only relies on pure mechanical automatic connection and does not need too much manual intervention, so the reliability is high.

[0041] The above embodiments of the present application are described in detail in combination with the drawings, and those skilled in the art can make various changes to the present application according to the above description. Therefore, some details in the embodiments should not constitute a limitation on the present application, and the scope of protection of the present application will be defined by the appended claims.
