Description

Technical Field

[0001] The invention relates to the technical field of ports and coastal engineering, and more particularly to an undulating flexible submerged dike with multiple wave-breaking functions. Background Art

[0002] A breakwater is an offshore engineering structure built to reduce the damage of waves to the coastline and protect ports and coastal engineering structures. At present, the most common types of breakwaters are slope breakwaters, vertical breakwaters and submerged breakwaters. Slope breakwaters and vertical breakwaters mainly block waves directly with a levee body that is higher than the designed wave height. The wave-breaking effect is obvious, but their construction and maintenance costs are high, the construction period is long, and they cannot adapt to deep water conditions. At the same time, slope breakwaters and vertical breakwaters will block the exchange of seawater inside and outside the breakwater, which has a greater impact on the environment. Submerged breakwaters are breakwaters with the top of the levee below the water surface. When waves go over the submerged breakwater, the water depth at the top of the levee suddenly decreases, and the waves will break, which can reduce the wave action on the coast or revetment. Compared with slope breakwaters and vertical breakwaters, submerged breakwaters do not affect water exchange and have little impact on the ecological environment.

[0003] At present, submerged dikes usually adopt rigid structures such as riprap, concrete blocks or small reinforced concrete caissons. Due to cost constraints, rigid submerged dikes are also difficult to arrange in deep water conditions. In addition, rigid submerged dikes mainly consume wave energy through a single wave-breaking effect, and their wave-breaking effect often cannot meet actual engineering needs. Summary of the invention

[0004] In view of this, the present invention provides an undulating flexible submerged dike with multiple wave-breaking functions, which can solve the problems of high cost, poor water depth adaptability and poor wave-breaking performance of current traditional rigid submerged dikes.

[0005] To achieve the above-mentioned purpose, the present invention provides an undulating flexible submerged dike with multiple wave-breaking functions, comprising a supporting assembly and an undulating wave-breaking mechanism, wherein the undulating wave-breaking mechanism comprises a horizontal wave-breaking plate and a flexible water bag arranged on the top of the horizontal wave-breaking plate, and the undulating wave-breaking mechanism is movably connected to the supporting assembly, and the wave-breaking function of the wave is achieved through the periodic heaving motion of the undulating wave-breaking mechanism relative to the supporting assembly and the periodic back and forth swinging motion of the flexible water bag.

[0006] Preferably, the support assembly includes a bottom base plate and a plurality of columns, the columns are vertically arranged around the top surface of the bottom base plate, and the horizontal wave-breaking plates are penetrated on the columns around their peripheries.

[0007] Preferably, a plurality of connecting springs are provided between the bottom surface of the horizontal wave-breaking plate and the top surface of the bottom base plate, and the connecting springs are used to make the horizontal wave-breaking plate and the flexible water bag perform periodic vertical swing motion relative to the bottom base plate along the axial direction of the column.

[0008] Preferably, a stop assembly is provided at the top end of the column, and the limit assembly is used to prevent the heave wave eliminating mechanism from detaching from the top end of the column.

[0009] Preferably, the stopping component is a circular ring, and the circular ring is connected to the top ends of several columns at the same time.

[0010] Preferably, the stopping assembly is a plurality of cross beams, and the plurality of cross beams are sequentially connected end to end to form a square frame structure, and the square frame structure is simultaneously connected to the top ends of a plurality of columns.

[0011] Preferably, the four vertices of the frame structure and the columns connected to the four vertices are connected via three-hole connectors.

[0012] It can be seen from the above technical solutions that, compared with the prior art, the present invention can not only enhance the wave reflection and breaking energy dissipation effect of the submerged dike by combining the horizontal wave-breaking board with the flexible water bag, but also can simultaneously utilize the up and down fluctuation of the horizontal wave-breaking board and the left and right swing of the flexible water bag to generate vortex to dissipate wave energy, thereby further improving the wave-breaking effect. In addition, the present invention has the following beneficial effects: 1. Compared with the traditional gravity breakwater, the present invention will not affect the water exchange around the breakwater, nor will it destroy the surrounding ecological balance, has less impact on the environment, and is more environmentally friendly; 2. The present invention does not require a large amount of building materials to construct, has low cost, and is easy to construct and assemble; 3. The present invention can be installed under different water depths. Only the spring height needs to be adjusted under different water depths, which makes up for the shortcoming that traditional rigid submerged dikes cannot be used in deep water.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Please see attached Figure 1 , which is an undulating flexible submerged dike with multiple wave-breaking functions disclosed by the present invention.

[0018] The undulating flexible submerged dike with multiple wave-breaking functions provided by the present invention comprises a supporting assembly and an undulating wave-breaking mechanism, wherein the undulating wave-breaking mechanism is movably connected to the supporting assembly.

[0019] The support assembly includes a bottom base plate 1, a connecting spring 2, a column 3, a three-hole connector 6, and a crossbeam 7. The bottom base plate 1 is a flat plate with a certain thickness, which can be a square plate or a circular plate, etc. A plurality of columns 3 are arranged around the top surface of the bottom base plate 1, and the columns 3 are arranged vertically.

[0020] Specifically, when the bottom base plate 1 is a square plate, its four corners are provided with mounting holes for installing columns 3 and mounting holes for installing connecting springs 2, the lower ends of the four columns are connected to the column mounting holes at the four corners of the bottom base plate 1, the connecting springs 2 are installed in the connecting spring mounting holes and the top ends of the connecting springs 2 are connected to the undulating mechanism, and the top ends of the four columns 3 are connected to a plurality of beams 7 through three-hole connectors 6, and the plurality of beams 7 are connected end to end in sequence to form a square structure; when the bottom base plate 1 is a circular plate, a plurality of columns 3 are installed on the outer circumference of its top surface, and the top ends of the plurality of columns 3 are connected to the circular rings one by one, wherein the annular cross section of the circular rings is placed horizontally.

[0021] It should be noted that the frame structure and the circular ring composed of a number of beams 7 are both stopper components, which are used to prevent the heave wave-breaking mechanism from detaching from the top of the column 3 and to improve the overall stability of the support component.

[0022] The undulating wave-breaking mechanism includes a horizontal wave-breaking plate 4 and a flexible water bag 5. The horizontal wave-breaking plate 4 is penetrated on the column 3 around the periphery, and the horizontal wave-breaking plate 4 is slidably connected with the column 3. The flexible water bag 5 is arranged on the top of the horizontal wave-breaking plate 4. The flexible water bag 5 can produce periodic forward and backward swinging motion under the action of waves. The bottom of the horizontal wave-breaking plate 4 is elastically connected to the top of the bottom plate 1 by a connecting spring 2. The connecting spring 2 provides conditions for the up and down undulating motion of the horizontal wave-breaking plate 4 and the flexible water bag 5, that is, the horizontal wave-breaking plate 4 and the flexible water bag 5 are periodically swung relative to the bottom plate 1 along the axial direction of the column 3. Therefore, the wave-breaking effect on waves is achieved through the dual effects of the periodic swung motion of the undulating wave-breaking mechanism relative to the supporting assembly and the periodic forward and backward swing motion of the flexible water bag 5.

[0023] Specifically, when the bottom base plate 1 is a square plate or a circle, the four corners of the horizontal wave-breaking plate 4 are respectively provided with holes corresponding to the column mounting holes on the bottom base plate 1 so that the four columns 3 can pass through them. Preferably, a slide rail is provided in the hole to make the sliding between the horizontal wave-breaking plate 4 and the column 3 smoother.

[0024] The operating principle of the present invention is: The undulating flexible submerged dike is submerged at a certain position below the water surface, and the horizontal wave-breaking board 4 on the submerged dike performs periodic heaving motion together with the flexible water bag 5 through the connection spring 2 under the action of waves. At the same time, the flexible water bag 5 itself also performs periodic swinging motion back and forth under the action of waves. Therefore, the wave-breaking effects of the undulating flexible submerged dike are mainly: ① the reflection effect of the overall structure on the waves, ② the breaking energy consumption of the waves on the upper part of the structure, ③ the vortex shedding energy consumption caused by the undulating motion of the horizontal wave-breaking board 4, and ④ the vortex consumption of the wave energy generated by the swinging back and forth of the flexible water bag 5.

[0025] The present invention combines the horizontal wave-breaking plate 4 with the flexible water bag 5, which not only enhances the wave reflection and breaking energy dissipation effect of the undulating flexible submerged dike, but also can simultaneously utilize the up and down fluctuation of the horizontal wave-breaking plate 4 and the back and forth swinging of the flexible water bag 5 to generate vortex to dissipate wave energy, thereby further improving the wave-breaking effect.

[0026] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
