Description

A device for measuring wave height

technical field

The utility model relates to a wave height measurement device, in particular to a seawall wave height measurement device in a wave section test.

Background technique

When the wave propagates from the deep water area to the coast, the difference between the elevation of the water body along the dike surface and the elevation of the still water is called the wave elevation. The height of waves has an important impact on the erosion of the coast and the safety of seawalls. In order to better understand the wave climbing of engineering seawalls, it is often necessary to use physical model test simulations.

The existing wave height measurement methods mainly include naked eye observation and video measurement. Visual observation is by setting a ruler or a label outside the glass of the wave tank, and observing and recording the wave climb value with the naked eye during the action of a wave sequence, which is time-consuming and laborious and has low accuracy. Video measurement uses a camera to shoot a sequence of images of wave climb, and then post-processes the images to obtain the climb value. This method has good accuracy but high cost and complicated steps.

Utility model content

The above-mentioned seawall faces the side facing the water surface.

Working principle: The wave height measuring device of this utility model, according to the wave height measuring principle of the wave height meter, places it parallel and close to the surface of the seawall to measure the wave height; the width of the simulated seawall is half of the width of the wave tank, and the other half of the water tank It is used to eliminate the secondary reflection of the wave, and the middle is separated by a glass plate; before the test starts, water of different water depths is added to the wave tank, and the wave height meter is calibrated according to the change of the water surface elevation. In the test, the computer controls the wave machine to generate the wave sequence corresponding to the working condition in the wave tank through the wave-making software, and the wave height meter can record the wave climbing sequence acting on the seawall and save it to the computer.

The other end of the wave tank is provided with a gentle slope, and the surface of the gentle slope faces the simulated seawall; it can dissipate waves behind the simulated seawall.

The above-mentioned gentle slope is set behind the simulated seawall.

The wave tank is a glass wave tank; since the two ends of the seawall are in contact with the glass on both sides of the wave tank in the test, the viscous resistance of the glass has an important influence on the wave field at both ends of the seawall, so only the middle part of the seawall width needs to be measured. The climb can represent the wave climb of the test seawall section.
