Abstract

The present invention relates to the field of port and coastal engineering technology, and discloses an undulating flexible submerged dike with multiple wave-breaking functions, including a support assembly and an undulating wave-breaking mechanism. The undulating wave-breaking mechanism includes a horizontal wave-breaking plate and a flexible water bag arranged on the top of the horizontal wave-breaking plate. The undulating wave-breaking mechanism is movably connected to the support assembly, and the undulating wave-breaking mechanism performs periodic vertical swinging motion relative to the support assembly, and the flexible water bag performs periodic back-and-forth swinging motion. The present invention combines the horizontal wave-breaking plate with the flexible water bag, which not only enhances the wave reflection and crushing energy dissipation effects of the submerged dike, but also simultaneously utilizes the up and down undulation of the horizontal wave-breaking plate and the left and right swinging of the flexible water bag to generate vortices to dissipate wave energy, thereby further improving the wave-breaking effect. In addition, the present invention can be installed under different water depth conditions, which makes up for the disadvantage that traditional rigid submerged dikes cannot be applied to deep water.

Description

Technical Field

[0001] The present 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 wave damage to the coastline and protect ports and coastal engineering structures. Currently, the most common types of breakwaters are slope breakwaters, vertical breakwaters, and submerged breakwaters. Slope breakwaters and vertical breakwaters mainly use embankments that are higher than the design wave height to directly block waves. They have a significant wave-blocking effect, 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 significant impact on the environment. A submerged breakwater is a breakwater with a crest below the water surface. When waves pass over the submerged breakwater, the water depth at the crest suddenly drops, causing the waves to 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 less impact on the ecological environment.

[0003] At present, submerged dikes usually adopt rigid structures such as riprap, concrete blocks or reinforced concrete small caissons. Due to cost constraints, rigid submerged dikes are also difficult to deploy 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 objectives, the present invention provides an undulating flexible submerged dike with multiple wave-breaking functions, which includes a supporting assembly and an undulating wave-breaking mechanism. The undulating wave-breaking mechanism includes a horizontal wave-breaking plate and a flexible water bag arranged on the top of the horizontal wave-breaking plate. The undulating wave-breaking mechanism is movably connected to the supporting assembly, and the wave-breaking function is achieved through the periodic vertical swinging 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 arranged around the columns.

[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 swinging motion relative to the bottom base plate along the axial direction of the column.

[0008] Preferably, a stopping assembly is provided at the top end of the column, and the limiting assembly is used to prevent the heaving 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 connected end to end in sequence 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 corners of the frame structure and the columns connected to the four corners are connected via three-hole connectors.

[0012] As can be seen from the above technical solution, compared with the existing technology, the present invention combines horizontal wave-breaking plates with flexible water bags, which not only enhances the wave reflection and energy dissipation of the submerged dike, but also simultaneously utilizes the ups and downs of the horizontal wave-breaking plates and the left and right swings of the flexible water bags to generate vortices to dissipate wave energy, further improving the wave-breaking effect. In addition, the present invention has the following beneficial effects:

[0013] 1. Compared with traditional gravity breakwaters, the present invention does not affect the water exchange around the breakwater, nor does it destroy the surrounding ecological balance. It has less impact on the environment and is more environmentally friendly.

[0014] 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;

[0015] 3. The present invention can be installed under different water depth conditions. Under different water depths, only the spring height needs to be adjusted, which makes up for the shortcoming that traditional rigid submerged dikes cannot be used in deep water.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0020] Please see the attached Figure 1 , which is an undulating flexible submerged dike with multiple wave-breaking functions disclosed by the present invention.

[0021] The undulating flexible submerged dike with multiple wave-breaking functions provided by the present invention comprises a support assembly and an undulating wave-breaking mechanism, wherein the undulating wave-breaking mechanism is movably connected to the support assembly.

[0022] 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. A number of columns 3 are arranged around the top surface of the bottom base plate 1, and the columns 3 are arranged vertically.

[0023] 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 number of beams 7 through three-hole connectors 6, and the several 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 number of columns 3 are installed on the outer circumference of its top surface, and the top ends of the several columns 3 are connected to the circular ring one by one, wherein the annular cross-section of the circular ring is placed horizontally.

[0024] It should be noted that the frame structure and the circular ring composed of several beams 7 are both blocking components, which are used to prevent the heaving wave-breaking mechanism from detaching from the top of the column 3 and improve the overall stability of the support component.

[0025] The undulating wave-breaking mechanism includes a horizontal wave-breaking plate 4 and a flexible water bag 5. The four sides of the horizontal wave-breaking plate 4 are passed through the column 3. The horizontal wave-breaking plate 4 and the column 3 are slidably connected. 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 back-and-forth swinging motion under the action of waves. The bottom of the horizontal wave-breaking plate 4 and the top of the bottom plate 1 are elastically connected 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 support assembly and the periodic back-and-forth swing motion of the flexible water bag 5.

[0026] 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.

[0027] The operating principle of the present invention is:

[0028] The undulating flexible submerged dike is submerged below the water surface to a certain position. The horizontal wave-breaking plates 4 on the dike, connected to the springs 2, perform periodic heaving motion together with the flexible water bladder 5 under the action of waves. At the same time, the flexible water bladder 5 itself also performs periodic back-and-forth swaying motion under the action of waves. Therefore, the wave-breaking effects of the undulating flexible submerged dike are mainly: 1) the reflection of waves by the overall structure; 2) the energy dissipation caused by the breaking of waves on the upper part of the structure; 3) the energy dissipation caused by the vortex shedding caused by the undulating motion of the horizontal wave-breaking plates 4; and 4) the vortex generated by the back-and-forth swaying of the flexible water bladder 5, which consumes wave energy.

[0029] The present invention combines the horizontal wave-breaking plate 4 with the flexible water bag 5, which not only enhances the wave reflection and crushing 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.

[0030] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily 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 is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
