According to the structure, through the optimized design, the wave dissipation effect and the structural stability of the breakwater are improved, and meanwhile the construction difficulty and cost are reduced. The structure is particularly suitable for ports, wharfs and coastal protection in the marine environment.

The utility model relates to the technical field of water conservancy cofferdams, in particular to a cofferdam body unit of a cofferdam. The cofferdam body unit provided by the utility model has good wave dissipation performance and stable performance, and comprises a cofferdam wall body, an auxiliary supporting part, a wave dissipation module and an extension part, wherein the cofferdam wall body, the wave dissipation module and the extension part form a concave upstream face, the concave upstream face can play a role in wave dissipation and flow guide on waves, and the upper layer holes and the lower layer holes which are evenly distributed in the cofferdam wall body are matched, so that water flow can be evenly distributed, and the impact effect of the water flow on the cofferdam body and the cofferdam area is reduced; furthermore, a cavity is further formed in the top of the cofferdam wall body and filled with solid filler, and the comprehensive effects of reducing the self weight, purifying water, reducing the cost, stopping silt loss, reutilizing solid waste and the like can be achieved at the same time; in addition, a pendant of a two-section type bevel structure is further arranged on the lower portion of the extending portion, oyster adsorption and fixation are facilitated, and the cofferdam body is secondarily reinforced through biological glue.

The application relates to a design method and device of a semi-penetrating composite sheet pile wharf structure, and belongs to the technical field of port engineering and coastal engineering. The steel pipe piles and sheet piles of the vertical bearing system and the high-position anchorage restraint system, the embedded depth and the anchor rod tension of the oblique anchor tension collaborative system are optimized and designed based on the reduced wave load spectrum and the soil pressure distribution. Finally, a bottom scouring isolation layer model is constructed, scouring simulation is carried out by using the bottom scouring isolation layer model, and relevant feedback results are generated by using the scouring simulation results. The application can configure the steel pipe piles and sheet piles of the vertical bearing system and the high-position anchorage restraint system, the embedded depth and the anchor rod tension of the oblique anchor tension collaborative system by multiple analysis of the measured wave data of a target port, can feed back and analyze according to the actual simulation situation, and can further improve the wave dissipation performance and the structural bearing capacity.

The present application relates to the technical fields of ocean engineering, and particularly relates to a wave power generation device, comprising at least one single wave power generation unit, the single wave power generation unit comprising: a floating body module, configured to be placed on the sea surface to receive wave action and generate heave motion; two bottom anchoring members, a lower connecting member rigidly connected between the two bottom anchoring members at both ends; two power generation damping units, each power generation damping unit having a fixed end and a movable end, the fixed end being hingedly connected to the bottom anchoring member; two groups of upper cables, symmetrically and obliquely arranged, the lower end of each group of upper cables being connected to the movable end of the corresponding power generation damping unit, and the upper end being connected to the floating body module to pull the movable end when the floating body module performs heave motion; wherein the two bottom anchoring members are kept at a fixed distance apart by the lower connecting member, and the two groups of upper cables are symmetrically and obliquely arranged, so that when the floating body module deflects, a restoring moment opposite to the deflection direction is formed between the two movable ends.
