Detailed Description
For a better understanding of the present invention, the contents of the present invention will be further explained below with reference to the drawings and examples, but the present invention is not limited to the following examples.
In one embodiment, as shown in fig. 1, the present invention provides a wave-absorbing device, which mainly includes: the wave absorption dike 100, the wave absorption block 200, the support rod 300 and the flow separation layer plate 400; the wave-absorbing dike 100 is composed of wave-absorbing blocks 200 which are uniformly distributed; the support rod 300 is arranged at the bottom of the breakwater 100, and the support rod 300 extends upwards in an inclined way relative to the breakwater 100; the flow separation layer plate 400 is arranged at the top of the breakwater 100, and the flow separation layer plate 400 extends along the direction of the support rod 300 and is clamped with the support rod 300; the flow-separation layer plate 400 is uniformly provided with convex ribs 410.
Wherein the breakwater 100 may be disposed at the water bottom adjacent to the bank 110. The breakwater 100 may be a long dike underwater. Specifically, the front surface of the breakwater 100 may face deep water, and the back surface of the breakwater 100 may face the bank 110. The height of the breakwater 100 may be lower than the height of the bank 110. The breakwater 100 may block a rapidly advancing wave, consume its enormous energy, and change the advancing speed of the wave, changing the wave length/wave length of the wave and the wave crest/trough of the wave.
The wave absorption blocks 200 may be multiple and are uniformly distributed on the wave absorption dike 100. Specifically, the wave absorbing blocks 200 may be uniformly distributed around the wave absorbing bank 100 to alleviate the impact force of the waves. The support bar 300 may be disposed at the bottom of the breakwater 100, and the support bar 300 may be disposed at a side of the breakwater 100 adjacent to the bank 110. The support bar 300 may extend obliquely upward with respect to the breakwater 100, and in particular, the support bar 300 may form an angle of 30 ° to 60 ° with the side of the breakwater 100.
The flow-barrier sheets 400 may be disposed on top of the breakwater 100, and the flow-barrier sheets 400 may be disposed on a side of the breakwater 100 adjacent to the bank 110. The flow barrier plates 400 may extend in the direction of the support rod 300 to be engaged with the support rod 300. That is, in the present embodiment, one end of the support rod 300 is clamped to the bottom of the breakwater 100, and the other end of the support rod 300 is clamped to the flow-separation layer plate 400; one end of the current-isolating layer plate 400 is clamped with the top of the breakwater 100, and the other end of the current-isolating layer plate 400 is clamped with the support rod 300. The flow-separation laminated plate 400 can be uniformly provided with the convex ribs 410, and the convex ribs 410 can block the flow layer of the billow waves and consume the energy of the waves by being uniformly distributed on the flow-separation laminated plate 400.
In this embodiment, the breakwater 100 may block the rapidly advancing waves, consume the energy of the waves, and change the advancing speed of the waves; when water flows through disordered gaps of the wave elimination block 200, vortex flow is generated immediately and changed into disordered flow in a disordered direction, so that the wave elimination effect can be achieved; the current-isolating layer plate 400 blocks the current layer of the billow, consumes the energy of the wave, enables the rising water flow to not rise and the falling water flow to not fall, blocks the wave which advances rapidly, changes the frequency of the wave, reduces the wave crest of the wave, relieves the impact force of the wave, and protects the bank.
In one embodiment, as shown in fig. 2, the wave-absorbing block 200 may be a three-dimensional four-corner structure; four corners of the wave-absorbing block 200 are respectively provided with a steel ring 210. Wherein, two steel rings 210 can be arranged at each corner of the wave-absorbing block 200. When the waves rush to the wave-absorbing dam, the water flow generates vortex immediately when passing through the disordered gaps of the wave-absorbing block 200 and becomes disordered flow in the disordered direction, thereby consuming the energy of the waves and achieving the effect of wave absorption.
As shown in fig. 2, in one embodiment, iron chains 220 are respectively disposed at four corners of the wave-absorbing block 200, and the number of the iron chains 220 corresponds to the number of the steel rings 210.
In one embodiment, the wave absorption blocks are connected through iron chains. In this embodiment, the wave absorption blocks are connected in series through the iron chain, so that the wave absorption blocks can be prevented from being washed away by the surge.
In one embodiment, the flow barrier plates are steel plates. The flow separation layer plate can block the flow layer of the great waves, and consumes the huge energy of the waves, so that the ascending water flow cannot rise and the descending water flow cannot fall.
In one embodiment, as shown in FIG. 3, the ribs 410 are provided with relief holes 412. As shown in FIG. 3, in one embodiment, the relief hole 412 is rectangular in shape. The rectangular relief holes 412 in the ribs 410 not only reduce the weight of the flow barrier 400 and reduce the impact of waves on the flow barrier 400, but also prevent horizontally advancing waves from being blocked by vertical water flow through the relief holes 412.
In one embodiment, the wave breaker, the flow-isolating layer plate and the support rod form a triangle, so that the stability of the wave breaker, the flow-isolating layer plate and the support rod can be improved.
In one embodiment, the breakwater has a trapezoidal cross section.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
