Wave dissipation system with slope height adjustment function and using method

Abstract

The invention discloses a wave dissipation system with a slope height adjustment function and a using method. The wave dissipation system comprises a wave dissipation device. The wave dissipation device comprises a base framework. The two sides of the base framework are each connected with a scalable arc frame. A parabolic oblique filter mesh is connected between the scalable arc frames. One end of each scalable arc frame is rotationally connected with the base framework, and the other end of each scalable arc frame matches a lifting device. A water storage device is arranged below the filter mesh, and the water storage device is connected with a water return pipe. The arc setting and slope adjustability of the wave dissipation device and the replacement of the high-density steel filter mesh according to different waves all can help to increase the wave dissipation distance, expand the applicability to the wave size and energy and improve the efficiency of wave dissipation, and conform to the economical principle. The high-density steel filter mesh can ensure that a wave falls into the water storage area after completely rushing onto the wave dissipation device and does not produce backwater, so as to prevent the influence of backwater on the original wave and problems with experimental data caused thereby.

Description

technical field [0001] The invention relates to a wave-absorbing system with adjustable slope height and a use method thereof, which are mainly used for eliminating reflected waves caused by a test device blocking waves in a model test. Background technique [0002] Model testing is a reasonable and effective technique for reproducing complex engineering problems in the laboratory. Due to the large area of ​​water storage geological forms such as oceans and rivers, the failure process of the bottom slope is not easy to observe. However, sometimes it is necessary to understand the failure mechanism of the bottom slope under hydraulic action in engineering. Therefore, in order to reproduce this form of failure, reasonable boundary conditions can be set in the laboratory, and a simplified model can be used to simulate the failure process. Compared with a single wave, the geological form of water storage such as the ocean has a large area. The water area can be simplified as a ...

Problems solved by technology

[0004] According to the investigation and research, the commonly used wave-absorbing devices on the market can be divided into the following three categories. The first category: simply set up in a slope shape to form a simple gravity-type wave-eliminating device similar to sandy beaches and river beaches. Its advantages are both Functional and economical, the disadvantage is that gravity wave dissipation is used. If the slope is set too high, it will easily lead to too high return water velocity, which will affect the effective wave. If it is too low, the wave dissipation device will extend longer, which will waste the size of the model test. ; The second category: Lay rough products such as nylon on the first category of slopes as flow blocking devices. High; the third type arranges square holes in a matrix on the slope, and its wave-absorbing effect is more practical on the actual coastline and river bank. In the model test with size restrictions, its wave-absorbing effect needs to be further improved

The common disadvantage of the above-mentioned materials is that they only have a cancellation effect on certain ranges or specific wave bands, but their ability to absorb waves for different wave bands is obviously insufficient
