Embodiment 1

[0033] A schematic diagram of a breakwater model with variable slope angles in this embodiment is as follows figure 1 As shown, it includes top plate 1, stressed slope surface 2, lead screw 3, bottom support structure 4, anti-wave parapet 5 (optional installation according to experimental requirements and working conditions). The top plate is hinged with the stressed slope and the angle of the joint can be adjusted freely, and the top plate is always horizontal. One end of the lead screw is fixed to the bottom support structure, and the other end is connected to the stressed slope. The inclination angle between the stressed slope surface and the horizontal plane can be adjusted through the lead screw. The stressed slope is connected with the bottom supporting structure by four hinges. When the anti-wave parapet is selected, it can be fixed on the top plate with screws. There is space for screw adjustment in the middle of the top plate. In order to reduce the weight and fac...

Abstract

The invention provides a breakwater model with a variable slope angle and an experimental system of the breakwater model. The breakwater model comprises a bottom supporting structure, a stress slope hinged to one end of the bottom structure, a top plate arranged at the other end of the stress slope, and a lead screw, one end of the lead screw is hinged to the stress slope, the other end of the lead screw is fixed to the bottom supporting structure, a through hole is formed in the top plate, and the lead screw penetrates through the through hole. During an experiment, the slope surface can be conveniently subjected to continuous adjustment of any angle from 20 degrees to 90 degrees through the lead screw so as to facilitate researching on the influence of angle change on the wave pressure distribution law, the wave pressure maximum value and the action position of the wave pressure maximum value, meanwhile, the climbing and crushing effects of waves on slopes of different angles can beobserved, and a foundation is provided for breakwater design.

Description

technical field [0001] The invention relates to a breakwater model and an experimental system thereof, in particular to a breakwater model with a variable slope angle and an experimental system thereof, belonging to the technical field of marine engineering experiments. Background technique [0002] One of the main external forces on breakwaters in coastal and offshore engineering is wave force. The study of wave forces acting on breakwaters determines the realization of engineering goals and the stability and safety of buildings. The slope surfaces of the existing breakwater models are fixed angles, which is inconvenient to study the wave force on slope breakwaters with different angles. Contents of the invention [0003] The object of the present invention is to provide a breakwater model with variable slope angle and an experimental system thereof in order to overcome the deficiency of the existing breakwater model. [0004] The purpose of the present invention is achi...
