Description

Technical Field

[0001] This invention relates to the field of hydraulic experimental model design, and in particular to an experimental device for a flexible wave-dissipating submerged breakwater. Background Technology

[0002] Most breakwaters in China are sloping earth-rock dam structures. Traditional structures require significant amounts of stone and sand, and construction is extremely demanding. In recent years, with continuous technological innovation, many regions have proposed the concept of "new-type breakwaters," replacing traditional structures with novel designs. These breakwaters generally draw inspiration from port engineering structures, effectively improving project quality and efficiency. The concept of "membrane breakwaters," as a new type of breakwater, also draws inspiration from structures like water-blocking dams and temporary cofferdams in river protection engineering. These structures typically consist of lightweight, high-strength membrane materials and rigid support materials. They are usually filled with air, water, sand, mud, or foam into a membrane bag, hence the common names "air / water / mud bags" or "air / water / mud bladders." Their advantages include simple structure, short construction time, and good seismic performance. Membrane breakwater structures can be mainly divided into two categories: submerged and floating. Submerged breakwaters, as sacrificial breakwaters, can be fixed to breakwater structures, serving as a structural form to protect and stabilize breakwaters. They can also provide seasonal coastal protection; in the event of extreme weather, they can be selectively inflated with water or air to form a breakwater.

[0003] Because the interaction between flexible wave-dissipating submerged breakwaters and waves is very complex, it is difficult to accurately analyze this physical process using only theoretical analysis methods or computer numerical simulations. Therefore, conducting physical model experiments is of great significance for studying the effectiveness of such structures.

[0004] In current glass water tank model experiments, nails are typically used to directly secure the experimental model to prevent movement. However, experiments require constant adjustments to the water level inside the model, and the rubber membrane cannot be submerged in water for extended periods, necessitating frequent relocation of the experimental setup, making nailing unsuitable. Some inventions have proposed adding counterweights to the front and rear of the experimental model, using wires to hold the structure in place. However, in actual experiments, because the lateral wave force is far greater than the frictional force of the counterweights, the counterweights are prone to shifting and damaging the glass water tank walls, and this also causes lateral movement of the experimental model. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a flexible wave-dissipating submerged breakwater experimental device to solve the problem that the existing methods of fixing the breakwater experimental model have poor stability and affect the experimental accuracy.

[0006] To achieve the above and other related objectives, this invention provides an experimental device for a flexible wave-dissipating submersible breakwater, comprising: a glass water tank, a fixed plate fixedly mounted at the bottom of the glass water tank, a first U-shaped opening groove on the fixed plate, the first U-shaped opening groove including a first upper wall plate and a first lower wall plate, the first upper wall plate having an embedding hole; a flexible breakwater model including a support frame, a flexible sealing membrane mounted on the support frame, the flexible sealing membrane and the support frame forming a sealed cavity filled with water; a retaining plate at the bottom of the support frame, the retaining plate having an elastic buckle, the retaining plate being engaged in the first U-shaped opening groove, and the elastic buckle being embedded in the embedding hole of the first upper wall plate; and a wave height measuring instrument disposed within the glass water tank, the wave height measuring instrument being used to measure the height of waves.

[0007] Preferably, the support frame includes a base plate and two semi-circular side plates. The base plate is provided with a second U-shaped opening groove, which includes a second upper wall plate and a second lower wall plate. The two semi-circular side plates are respectively fixedly disposed at the front and rear ends of the second upper wall plate. The second lower wall plate forms the retaining plate, and the elastic buckle is disposed on the second lower wall plate.

[0008] Preferably, the semi-circular side plate is bonded and fixed to the second upper wall plate.

[0009] Preferably, the flexible sealing film is adhered to the support frame, or the flexible sealing film is fixed to the support frame by nails.

[0010] Preferably, the flexible sealing membrane is made of rubber, and the support frame is made of plexiglass.

[0011] Preferably, the flexible sealing membrane is provided with a water inlet pipe.

[0012] Preferably, the water inlet pipe is equipped with a rubber valve.

[0013] Preferably, there are two wave height measuring instruments, which are respectively set on the left and right sides of the flexible breakwater model, and the distance between each wave height measuring instrument and the flexible breakwater model is 1.2m to 3m.

[0014] Preferably, there are two elastic buckles, which are respectively disposed at the front and rear ends of the card plate; there are two embedding holes, which are respectively disposed at the front and rear ends of the first upper wall plate.

[0015] Preferably, the elastic buckle includes a spring and a buckle body, one end of the spring is fixed to the buckle plate, and the other end of the spring is connected to the buckle body, which is hemispherical.

[0016] As described above, the flexible wave-dissipating submersible breakwater experimental device of the present invention has the following beneficial effects: In use, the flexible breakwater model is fixed by sliding the locking plate at the bottom of the support frame into the first U-shaped opening groove on the fixing plate. Furthermore, the stability of the flexible breakwater model is further improved by the elastic buckle on the locking plate embedded in the first upper wall plate of the first U-shaped opening groove. When disassembly is required, the locking plate can be slid out of the first U-shaped opening groove by pressing the elastic buckle. Compared with the prior art method of setting counterweights on the experimental model, the fixing method of the flexible breakwater model of the present invention has high stability, is convenient for disassembly and installation, and has a simple structure. At the same time, since the height of the elastic buckle is much smaller than the height of the flexible breakwater model and is located on the back of the flexible breakwater model, compared with the prior art method of fixing it with counterweights, the fixing method of the present invention can also avoid affecting the flow field before and after the flexible breakwater model, thereby improving the accuracy of the experiment.

[0045] Please see Figures 1 to 4 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0046] This invention provides an experimental device for a flexible wave-dissipating submerged breakwater, such as... Figures 1 to 3 As shown, the experimental device for a flexible wave-dissipating submersible breakwater includes a glass water tank 10, a flexible breakwater model 20, and a wave height measuring instrument 30. A fixing plate 11 is fixedly mounted at the bottom of the glass water tank 10. The fixing plate 11 has a first U-shaped opening groove 110, which includes a first upper wall plate 111 and a first lower wall plate 112. An embedding hole 1110 is provided on the first upper wall plate 111. The flexible breakwater model 20 includes a support frame 21, on which a flexible sealing membrane 22 is provided. The flexible sealing membrane 22 and the support frame 21 form a sealed cavity, which is filled with water. A retaining plate is provided at the bottom of the support frame 21, and an elastic buckle 210 is provided on the retaining plate. The retaining plate is engaged in the first U-shaped opening groove 110 on the fixing plate 11, that is, between the first upper wall plate 111 and the first lower wall plate 112. The elastic buckle 210 is embedded in the embedding hole 1110 on the first upper wall plate 111. The wave height measuring instrument 30 is set in the glass water tank 10. The wave height measuring instrument 30 is used to measure the height of the waves.

[0047] In use, the flexible wave-dissipating submersible breakwater experimental device of the present invention fixes the flexible breakwater model 20 by sliding the locking plate at the bottom of the support frame 21 into the first U-shaped opening groove 110 fixed on the fixing plate 11 at the bottom of the glass water tank, i.e., locking it between the first upper wall plate 111 and the first lower wall plate 112 of the first U-shaped opening groove 110. Furthermore, the stability of the flexible breakwater model is further improved by the elastic buckle 210 on the locking plate being embedded in the embedding hole 1110 on the first upper wall plate 111 of the first U-shaped opening groove 110. When disassembly is required, the locking plate can be slid out of the first U-shaped opening groove 110 by pressing the elastic buckle 210. Compared with existing technologies that use counterweights on experimental models, the present invention provides a more stable and convenient method for fixing flexible breakwater models. It is also simple in structure, highly reproducible, and can be extended to other model experiments that require frequent movement. Furthermore, because the height of the elastic clips is much smaller than the height of the flexible breakwater model, and they are located on the back of the model, the fixing method of the present invention avoids affecting the flow field at the front and back of the flexible breakwater model, unlike the existing method of using counterweights. This further improves the accuracy of the experiment.

[0048] Preferred, such as Figure 2 As shown, in this embodiment, the support frame 21 includes a base plate 211 and two semi-circular side plates 212. The base plate 211 has a second U-shaped opening groove 2110, which includes a second upper wall plate 2111 and a second lower wall plate 2112. The two semi-circular side plates 212 are respectively fixedly disposed at the front and rear ends of the second upper wall plate 2111. The second lower wall plate 2112 forms the retaining plate, and an elastic buckle 210 is disposed on the second lower wall plate 2112. With this structural design, when the flexible breakwater model 20 is fixed into the glass water tank 10, as... Figure 4 As shown, the second lower wall plate 2112 of the second U-shaped opening slot 2110 is slidably inserted into the first U-shaped opening slot 110 on the fixing plate 11, that is, sandwiched between the first upper wall plate 111 and the first lower wall plate 112 of the first U-shaped opening slot 110. When sliding the second lower wall plate 2112 into the first U-shaped opening slot 110, the elastic buckle 210 on the locking plate, i.e., the second lower wall plate 2112, needs to be pressed to prevent interference. Then, when the second lower wall plate 2112 is inserted in place, that is, when the elastic buckle 210 corresponds to the embedding hole on the first upper wall plate 111 of the first U-shaped opening slot 110, the elastic buckle 210 springs up and embeds itself in the embedding hole 1110, thereby fixing the flexible breakwater model. When disassembly is required, the second lower wall plate 2112 can be slid out of the first U-shaped opening slot 110 by pressing the elastic buckle 210. The structure is simple and the operation is convenient.

[0049] Furthermore, to improve the stability of the flexible breakwater model fixed in the glass tank, preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, two elastic buckles 210 are provided on the card plate, i.e., the second lower wall plate 2112. These two elastic buckles 210 are respectively disposed at the front and rear ends of the second lower wall plate 2112. Correspondingly, two fitting holes 1110 are provided on the first upper wall plate 111 of the first U-shaped opening groove 110. These two fitting holes 1110 are respectively disposed at the front and rear ends of the first upper wall plate 111. Of course, it should be noted that in other optional embodiments, those skilled in the art can provide any number of elastic buckles and corresponding fitting holes as needed.

[0050] Specifically, such as Figure 4 As shown, in this embodiment, the elastic buckle 210 includes a spring 2101 and a buckle body 2102. One end of the spring 2101 is fixed to the latch plate, i.e., the second lower wall plate 2112, and the other end of the spring 2101 is connected to the buckle body 2102. Preferably, the buckle body 2102 is hemispherical.

[0051] Specifically, in this embodiment, the two semi-circular side plates 212 of the support frame 21 are respectively glued to the front and rear ends of the second upper wall panel 2111. The flexible sealing film 22 is also glued to the support frame 21. In other optional embodiments, the flexible sealing film 22 can also be fixed to the support frame 21 with nails.

[0052] Preferably, in this embodiment, the support frame 21 is made of plexiglass, and the flexible sealing membrane 22 is made of rubber, i.e., the flexible sealing membrane is a flexible rubber membrane. Since the flexible breakwater model 22 has a sealed internal cavity filled with water, and the entire arc surface of the breakwater model is a flexible rubber membrane, i.e., a deformable structure, it is called a flexible breakwater model.

[0053] Furthermore, such as Figure 1 As shown, in this embodiment, a water inlet pipe 220 is provided on the flexible sealing membrane 22, through which water can be injected or released into the flexible breakwater model 20. Specifically, the water inlet pipe 220 is a glass tube.

[0054] Furthermore, a rubber valve 2201 is provided on the water inlet pipe 220. The rubber valve 2201 is used to block the water inlet pipe 220, so that when the flexible breakwater model 20 is subjected to external loads, the water inside the breakwater model will not overflow through the water inlet pipe.

[0055] Furthermore, such as Figure 1As shown, in this embodiment, two wave height measuring instruments 30 are provided, which are respectively set on the left and right sides of the flexible breakwater model 20. The distance between each wave height measuring instrument 30 and the flexible breakwater model 20 is 1.5×0.8m to 1.5×2m, that is, 1.2m to 3m. That is, during the experiment, waves need to be generated in the glass water tank by a wave generator. The distance between the wave height measuring instrument 30 and the flexible breakwater model 20 needs to be set according to the incident wave wavelength of the wave generator. That is, the distance between the wave height measuring instrument 30 and the flexible breakwater model is usually set to 1.5 times the incident wave wavelength.

[0056] Specifically, in other optional embodiments, multiple wave height measuring instruments can also be set on one side (left or right) of the flexible breakwater model 20. When multiple wave height measuring instruments are set on one side of the flexible breakwater model 20, the interval between two adjacent wave height measuring instruments should be greater than or equal to 0.5 times the incident wave wavelength of the wave generator.

[0057] In summary, the flexible wave-dissipating submersible breakwater experimental device of the present invention provides high stability for fixing the flexible breakwater model, is easy to disassemble and install, and has a simple structure. It can be extended to other model experiments that require frequent movement. Furthermore, the fixing structure of the present invention can avoid affecting the flow field before and after the flexible breakwater model, thereby improving the accuracy of the experiment. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0058] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
