A drum-type wave-dissipating device

Abstract

The invention discloses a drum-type wave breaking device which comprises multiple pile shafts, hollow sleeves and drum assemblies. The pile shafts are vertically arranged on the bottomland on the outer side of a dike at intervals; the pile shafts are sleeved with the hollow sleeves in a sliding mode; the drum assemblies are arranged between every two adjacent pile shafts. Each drum assembly comprises a rotary fixing shaft and a drum, wherein one end of the rotary fixing shaft is supported on the hollow sleeve on one of the two corresponding adjacent pile shafts, the other end of the rotary fixing shaft is supported on the hollow sleeve on the other of the two corresponding adjacent pile shafts, the drum is rotationally arranged on the rotary fixing shaft, and the outer drum face of the drum is provided with multiple blades at intervals in the circumferential directions. The drums serve as the wave breaking carriers, water rolling force is fully utilized to drive the drums to vertically move, the depth that the drums are thrown into still water is reasonably determined according to the characteristic that wave energy is concentrated on the surface of the water, the drums are pushed to rotate through power impact of wave, and in the rotating process of the drums, the blades on the drums are crushed by wave, so that the purpose of breaking wave is achieved.

Description

technical field [0001] The invention relates to the technical field of hydraulic wave dissipation, in particular to a drum type wave dissipation device. Background technique [0002] my country's rivers are vertical and horizontal, lakes are densely covered, the coastline is long, and the workload of dike protection and slope protection is heavy. Therefore, there are endless forms of wave prevention and wave dissipation, and they have been continuously optimized and innovated. Wave dissipation is an important part of embankment design. In the past, most embankments used engineering wave dissipation measures to reduce wave energy. At present, it is more common to use twisted I-shaped blocks at the foot of the seawall to eliminate wave kinetic energy. Lower waves climb higher. [0003] see figure 1 , shown in the figure is an existing wave-dissipating structure, including a number of twisted I-shaped blocks 2 stacked on the embankment foot or slope protection 1, and each twi...

Problems solved by technology

The device is only point-shaped, and its disadvantage is that it is difficult to form a wave-dissipating barrier and cannot form the continuity of wave-dissipating

[0006] Similarly, the applicant continued to carry out such research and made a bold attempt from another angle to solve the problem of unsatisfactory implementation effect of the current wave-dissipating structure and high cost of materials and construction
