Technical Field

The invention belongs to the field of wave absorption technical research, and particularly relates to a device suitable for wave absorption in a water pool experiment.

Background

The physical model experiment research is adopted in the wave water tank, the safety and reliability of the sea test of the device can be guaranteed, quantitative analysis can be performed, and the result is reliable. In a wave flume, a wave generator is an indispensable device, the main function of which is to generate waves. However, the wave can be reflected by the boundary of the wave water tank, and the reflected wave reciprocates between the wave making plate and the boundary to form multiple reflected waves, so that the accuracy of the model experiment is influenced. At present, wave absorption against shore in wave making water tanks and water pools at home and abroad is mostly in a slope type, and the most common material is broken stone. The wave absorption principle is as follows: the wave is made to run through the way of climbing the slope and the energy consumption is carried out. When a large-scale ship model test or a high-frequency oscillation test is carried out, irregular waves can be generated in a water pool, the test of the next working condition can be carried out only after the water surface is calm, and the process needs a long time, which is unacceptable for the ship model test with huge time cost. In order to solve the problem, a wave absorbing device is required to be arranged in the pool, and the existing wave absorbing device has the design schemes of a wave absorbing bank, a slope, a bar grid and the like, but the wave absorbing performance needs to be improved.

The invention patent with application publication number CN 110080158A, named as 'a pool with wave absorbing device', describes a pool with wave absorbing device. The tail end of the water pool is provided with an inclined wave-eliminating grid, and a cavity is formed between the back surface of the inclined wave-eliminating grid and the wall surface of the tail end of the water pool. The invention

The wave-absorbing device adopts a shutter type structure and is designed to be inclined; a cavity is designed behind the wave-absorbing plate, and eddy current is generated inside the cavity, so that the wave-absorbing plate is beneficial to consuming the energy of waves; in the wave absorbing device, the louver type wave absorbing plates in the wave absorbing device are arranged in a step shape, so that vortex flow is generated in the process that waves and flow climb and then fall into a cavity behind, and further the energy of water flow is consumed. The invention only generates vortex to consume energy to the water flow after the wave climbs and falls, and simultaneously, the invention still has larger energy at the moment that the water flow directly falls into the pool after freely falling through the same gap, thereby causing larger secondary wave. Because the device for limiting the falling direction of the water flow is not arranged in the invention, the water flow can not be ensured to fall along a certain direction, so that a stable and regular vortex can not be formed, and the wave-absorbing effect is not good. Meanwhile, the upper surface of each grid strip and the bottom surface of the water pool form a wave elimination grid with a shutter type structure at an elevation angle of 10-15 degrees, when waves are large, the waves are not favorable to fall into gaps in the climbing process, and reverse partial water flow flows back to the water pool again, so that large secondary waves are caused.

The invention patent with the publication number of CN 105951663B and the name of a wave absorbing device against the bank is a semi-open wave absorbing device against the bank, which consists of an edge plate, angle steel and a plurality of partition plates, wherein: the partition plates are uniformly arranged, two ends of each partition plate are respectively welded with the two side plates, and the bottoms of the two side plates are connected by angle steel; the plurality of partition plates are formed by welding arc-shaped panels and vertical panels, wherein the arc-shaped panels face upwards, and the vertical panels face downwards, so that vertical cavities are formed among the plurality of partition plates; the two side plates are both right-angle trapezoidal panels, and the middle triangular part is hollowed out. The invention makes the wave transmitted to the opposite bank do free falling motion between the gaps of the partition board in the process of climbing, consumes the wave energy, and further plays a role in inhibiting secondary or multiple reflected waves caused by the opposite bank pool wall. Because the invention only consumes energy of the water flow through the transient free falling of the water flow, and meanwhile, in the same gap, the water flow falls into the pool too intensively, thereby causing larger secondary waves.
