Description

Bidirectional multiple wave absorbing device
Technical Field
The utility model belongs to the technical field of the rivers wave absorption device, concretely relates to two-way multiple wave absorption device.
Background
The wave basin is the important place of carrying out the relevant research of wave, because the restriction in experiment place, and the length of wave basin is limited, when the basin closed end portion was propagated to the wave, can touch the end plate and reflect, and the back wave forms secondary and many times back wave at wave making board and border reciprocating motion between. The reflected waves continuously interfere with waves set by the experiment and are mutually superposed to form a very complex wave system, and if the reflected waves cannot be effectively eliminated, the flow field around the experiment model can be seriously influenced. The wave-absorbing device is an important device which is arranged at the end part of the wave water tank and is used for reducing wave energy and preventing reflected waves from influencing test results.
The wave absorption effect of different wave absorption devices is different, and the accuracy of the wave water tank test can be directly influenced by the quality of the wave absorption performance. The wave-absorbing device used in the existing wave water tank can be divided into an arc surface wave-absorbing device, a wire netting array wave-absorbing device, a box type wave-absorbing device and a slope type wave-absorbing device according to the geometrical shapes. For the water tank with fixed water depth, the circular arc surface wave-absorbing device has better wave-absorbing effect. However, the circular-arc-surface wave-absorbing device has an optimal water depth with the best wave-absorbing effect, and once the water depth in the water tank deviates from the optimal water depth, the device cannot achieve the good wave-absorbing effect. To the fixed basin of wave wavelength and wave height, wire netting battle array wave absorption device has better wave absorption effect. However, for the wire mesh array wave-absorbing device, the fact that the air permeability is unchanged along the way is a defect, so that the wave-absorbing device cannot achieve an effective wave-absorbing effect on the premise of small occupied space, and the box-type wave-absorbing device has the same wave-absorbing principle as the wire mesh array wave-absorbing device and also has the same wave-absorbing defect as the wire mesh array wave-absorbing device. The materials used by the slope type wave absorbing device are most common in the way of broken stones and bamboo branches, the wave climbing and the water body are utilized to generate whirling motion in the porous materials to consume energy, and the more gentle the slope is, the better the wave absorbing effect is. Although the wave absorbing device has a simple structure, the wave absorbing device also has the following disadvantages: the wave-absorbing device occupies too large space, has poor wave-absorbing effect, and the broken stones pollute the water body.
In order to eliminate the reflection influence of waves as much as possible, it is necessary to improve the structure of the existing wave-absorbing device to overcome the above-mentioned defects.
