Description

Technical Field

[0001] The invention relates to the field of wave and water flow simulation equipment, in particular to a deep water wave and water flow simulation pool. Background Art

[0002] At present, it is necessary to simulate the dynamic environment of the ocean in the process of ship or marine engineering research. The conventional method is to build a large pool and set up a wave maker and a flow system at the edge of the pool. The wave maker can generate periodic waves on the water surface, and the water flow is driven by a circulating water pump to form a water cycle in the pool to generate a flow field. The current wave and flow simulation pools are all built by digging deep on the ground. The depth of a deep pool is generally above 2.5m, and the depth of a shallow pool is generally below 1.2m. In order to set up a circulation channel for simulating the water flow in the pool, a return water corridor is generally dug on the side of the pool, and then a pumping device is used to form a water cycle.

[0003] The construction of a simulated water pool in this way is a large project, which not only requires large-scale excavation of soil, but also requires the opening of a return water corridor. The construction is time-consuming, labor-intensive and costly.

[0004] On the other hand, the water in the return corridor flows from the narrow diameter corridor into the wide simulated water pool, which will cause uneven water flow. The water flow velocity is too high in the area centered on the outlet and inlet of the return corridor, but the water flow velocity becomes smaller as it spreads outward, and a strong vortex is formed, which cannot form a uniform and stable water flow on the plane. The resulting ocean simulation conditions cannot meet the experimental requirements.

[0005] Secondly, in the traditional water pool, water flows out from the bottom of the pool into the test area, and the direction of the water jet is perpendicular to the direction of the waves. Due to the interaction between waves and water flow, the generated water flow will have a certain attenuation effect on the waves and affect the stability of the waves. It is impossible to simulate stable waves and water flow dynamic fields at the same time.

[0006] At present, the simulated water pools built in China are generally of two types: deep water and shallow water. The depth of deep water pools is generally above 2.5 meters, and the depth of shallow water pools is generally below 1.2 meters. However, there is still a gap in equipment technology for medium-deep water pools with a depth of between 1.2-2.5 meters. Summary of the invention

[0007] The main technical problem solved by the present invention is to design a deep-water wave and flow simulation pool which has a small construction workload, can simultaneously generate a stable wave and water flow dynamic field, and can more accurately simulate the ocean dynamic environment.

[0012] Furthermore, the first type of energy dissipation columns are distributed in a plum blossom pile array at the front end of the energy dissipation section; and the second type of energy dissipation columns are evenly distributed at the rear end of the energy dissipation section.

[0013] Furthermore, the rectifying device comprises a plurality of guide plates and flow diverters, wherein the guide plates are arranged at the front end of the rectifying section, and the flow diverters are arranged at the rear end of the rectifying section.

[0014] Furthermore, the guide plate is perpendicular to the ground and parallel to the water flow direction, and its height is 0.3 to 0.5 times the total height of the pool body; above the guide plate is a wave maker installation platform, and the wave maker is installed on the wave maker installation platform.

[0015] Furthermore, the wave-breaking device is a wave-breaking plate with a stacked structure, and the wave-breaking plate is obliquely arranged on the inner wall at the rear end of the pool body; the height of the wave-breaking device is 0.6 to 0.7 times the total height of the pool body, and the inclination slope is 1:4 to 1:3; the wave-breaking device includes three layers, which are, from top to bottom, an upper perforated plate, a water filter plate, and a lower perforated plate; a plurality of through holes are provided on the upper perforated plate and the lower perforated plate; a water filter channel is provided in the water filter plate, and the water filter channel is a curved channel; and a flow channel is provided below the wave-breaking plate.

[0016] Furthermore, an outflow section is arranged at the tail end of the wave-breaking section, and the top of the outflow section is opened and connected to the air; the front end of the outflow section is connected to the flow passage of the wave-breaking section.

[0017] Furthermore, a water inlet and a water outlet are provided on the pool body, wherein the water outlet is provided at the rear end of the pool body, and the water inlet is provided at the starting end of the pool body; the number of the water inlets and the water outlets is the same, and the water inlets and the water outlets are arranged correspondingly with the axis to the axis.

[0018] Furthermore, the circulation pipeline includes a water outlet, a water inlet, a return pipe and a circulating water pump. The water outlet is connected to the water inlet of the pool body, and the water inlet is connected to the water outlet of the pool body. The circulating water pump guides the test water from the water outlet to the water inlet to promote water flow and circulation.

[0019] Furthermore, the water pool is composed of a number of water pool units, each of which includes a partial water pool body, and an energy dissipation section, a flow straightening section, a test section, a wave absorption section and an outflow section arranged on the partial water pool body; the width of each of the water pool units is the same.

[0020] The beneficial effects of the present invention are:

The flow cutter provided in the rectifying device promotes the water flow upward, improves the vertical simulation accuracy of the water flow, and more realistically reproduces the actual flow field distribution law of the actual ocean water flow, where the upper layer is large and the lower layer is small. By providing multiple flow-making devices, the water circulation mode of the entire pool is changed into a mode of circulation through several evenly distributed circulating waterways. This circulation mode avoids the uneven water flow caused by the water in the return corridor pouring into the wide simulation pool from the narrow-diameter corridor. By providing a wave maker, the desired wave flow can be generated. At the same time, unlike the traditional water pool in which the direction of the water jet is perpendicular to the direction of the wave, the direction of the water jet in the present invention is almost parallel to the direction of the wave, which minimizes the mutual interference between the waves and the water flow when the two are simulated at the same time, and achieves the purpose of simulating waves and water flow accurately and stably at the same time.

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without creative work belong to the scope of protection of the present invention. In the description of the present invention, it should be noted that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0035] The present invention designs a medium-depth pool that is different from traditional deep pools and shallow pools. The depth of the pool is between 1.5 and 2.5 meters, and the pool body involved in the present invention is above the ground, and is not constructed by excavation. This not only avoids the high construction cost caused by excavating the pool, but also avoids the construction of the corresponding return water corridor. Because the present invention is built above the ground, the operation of the overall water flow can be guaranteed by installing the corresponding circulation pipeline, and at the same time, a circulation water pump is added to the return water pipeline to provide power for the circulating water source. The above-mentioned method avoids providing an alternative solution for the excavation pool and fills the equipment technology gap of the medium-depth pool. At the same time, energy dissipation sections, rectification sections, wave-breaking sections, etc. are set in the pool to minimize the mutual interference between waves and water flows when they are simulated at the same time, so as to achieve the purpose of simulating waves and water flows accurately and stably at the same time.

[0036] like Figure 1-4 A deep water wave flow simulation pool, characterized by comprising:

[0037] The pool body 100 is arranged on the ground, and the pool body 100 is a containing structure surrounded by four walls and a bottom surface;

[0038] The pool body 100 includes several functional sections, which are respectively: an energy dissipation section 110, a rectifying section 120, an experimental section 130, a wave-breaking section 140, and an outflow section 150 from the starting end to the end of the pool body 100, and the above-mentioned functional sections are connected in sequence; wherein, an energy dissipation device is arranged in the energy dissipation section 110, a rectifying device is arranged in the rectifying section 120, the experimental section 130 is used to generate stable waves and water flow and place test models, the wave-breaking section 140 is arranged with a wave-breaking device 500, and the outflow section 150 is arranged at the tail end of the wave-breaking section 140; the pool body 100 is also provided with a flow-making device 600 and a wave-making machine 700, and the flow-making device 600 includes several circulation pipelines, and the circulation pipelines are connected to the pool body 100 to form a circulation water circuit.

[0039] like Figure 3 As shown, the energy dissipation device includes an energy dissipation column 200, and the energy dissipation column 200 includes two types, namely, a type I energy dissipation column 210 and a type II energy dissipation column 220; the cross section of the type I energy dissipation column 210 is circular; the type II energy dissipation column 220 is a streamlined column, and the front end of its cross section is a wide end, and the rear end is a narrow end. The type I energy dissipation column 210 is distributed in a plum blossom pile array at the front end of the energy dissipation section 110; the type II energy dissipation column 220 is evenly distributed at the rear end of the energy dissipation section 110. The cross section of the type I energy dissipation column 210 is circular, and the distribution form of the plum blossom pile array helps to disperse the water flow that gushes violently from the water inlet. The type II energy dissipation column 220 is streamlined, and its front end width is large, and the width gradually decreases when transitioning to the tail end, which helps to guide the dispersed water flow. The water flow passes through the energy dissipation device to reduce the degree of excessive concentration of the water flow, meeting the needs of water flow simulation in model tests.

[0040] like Figure 1 As shown, the rectifying device includes several guide plates 300 and a flow cutter 400, wherein the guide plates 300 are arranged at the front end of the rectifying section 120, and the flow cutter 400 is arranged at the end of the rectifying section 120; the guide plates 300 are perpendicular to the ground and parallel to the direction of the water flow, and the height is 0.3 to 0.5 times the total height of the pool body; above the guide plates 300 is a wave machine installation platform 800, and a wave machine 700 is installed on the wave machine installation platform 800. The wave machine 700 can drive the water body in the upper layer of the pool to produce periodic waves, simulating the real state that the ocean waves are mainly generated on the surface. The flow cutter 400 is fixed at the bottom of the pool body 100, and the optimal slope is 1:3.3 to 1:42. The flow cutter 400 can guide the water flow to flow upward, ensuring that the real situation of the water flow velocity in the upper layer and the lower layer in the actual ocean is restored in the experimental section 130.

[0041] In order to prevent the waves at the tail end of the pool from being unable to dissipate and being transmitted back to the experimental section of the pool, the present invention designs a new type of wave absorbing device 500, which is installed above the wave absorbing section 140. Figure 1 and Figure 3 As shown. Figure 4 As shown, the wave-breaking device 500 is a wave-breaking plate with a stacked structure, and the wave-breaking plate is obliquely arranged on the inner wall at the rear end of the pool body 100; the height of the wave-breaking device is 0.6 to 0.7 times the total height of the pool body, and the inclination slope is 1:4 to 1:3; the wave-breaking device 500 includes three layers, from top to bottom, an upper perforated plate 510, a water filter plate 520, and a lower perforated plate 530; a plurality of through holes are provided on the upper perforated plate 510 and the lower perforated plate 530; a water filter channel is provided in the water filter plate 520, and the water filter channel is a curved channel. When the wave water enters the wave-breaking device 500, it first passes through the upper perforated plate 510 at the top. The holes of the upper perforated plate 510 are conducive to dispersing the water. A curved water flow channel is provided in the middle-layer water filter plate 520. After the water enters the curved channel, the energy of the water gradually dissipates, and finally flows out through the lower perforated plate 530 to reduce the remaining energy of the wave. In addition, as Figure 1 and Figure 3 As shown, the present invention provides a flow channel 900 below the wave-breaking section 140 to facilitate the water to flow out of the pool body 100; an outflow section 150 is provided at the tail end of the wave-breaking section 140, and the top of the outflow section 150 is opened and connected to the air, which plays a role in further stabilizing the water flow entering the water pipe; the front end of the outflow section 150 is connected to the flow channel 900 of the wave-breaking section 140.

[0042] In order to avoid the situation where a large amount of water flow in the original water return corridor enters and causes the water flow state in the pool to be uneven, the present invention sets a diversion water circulation mode. A water inlet and a water outlet are provided on the pool body 100, wherein the water outlet is provided at the rear end of the pool body 100, and the water inlet is provided at the starting end of the pool body 100; the number of the water inlet and the water outlet is the same, and the water inlet and the water outlet are arranged correspondingly in an axis-to-axis manner. The circulation pipeline includes a water outlet 610, a water inlet 630, a return pipe 620, and a circulating water pump 640, wherein the water outlet 610 is connected to the water inlet of the pool body 100, and the water inlet 630 is connected to the water outlet of the pool body 100, wherein the circulating water pump 640 introduces the test water from the water outlet 610 into the water inlet 630 to promote water flow circulation.

[0043] As a preferred embodiment, the present invention provides a flow generating device 600 including 10 circulation pipelines. Figure 2The dotted lines (not present in the actual device) divide the entire pool body 100 into 10 equal units. For the convenience of description, the top unit is called the first unit and the bottom unit is called the tenth unit. Each unit and the circulation pipe connected to it constitute a circulation pipeline. Figure 2 It can be seen that in the first circulation pipeline, the water outlet is set at the left end of the first unit, the water inlet is set at the right end of the unit, the water outlet end 610 of the circulation pipe is connected to the water inlet, and the water inlet end 630 is connected to the water outlet. The circulation water pump 640 set on the circulation pipe draws water in the pool from the water outlet of the first unit and injects it into the water inlet of the first unit, thereby ensuring that the water flow direction in the pool body 100 is consistent, all flowing from the water inlet to the water outlet. The water flow mode of other circulation pipelines is similar to that of the first circulation pipeline.

[0044] In addition, it should be noted that the diameter of the water inlet is one third of the width of the pool unit. The water inlet or the water outlet is opened at a position slightly lower in the middle of the pool body 100 .

[0045] In addition, to facilitate the construction of the pool, the present invention also provides a pool unit that can be spliced ​​into the facilities in the entire pool. Each pool unit includes a portion of the pool body 100, and a wave maker, a flow-making device, an energy dissipation device, a rectifying device, and a wave-breaking device arranged on the portion of the pool body 100; the width of each of the pool units is the same. The pool unit can be used on the basis of the construction of the pool wall and the bottom surface. After installation, they are connected together to form the internal structure of the pool. The spliced ​​pool units are then fixed inside the pool base to form a simulated pool with functions such as wave making, flow making, energy dissipation, rectifying, and wave breaking.

[0046] In addition, as another embodiment, a baffle is provided in the pool body 100, and the position of the baffle is as follows: Figure 1 The dashed line arrangement is shown in FIG. 1 , but the starting end of the baffle is located on the side wall of the left end of the pool body 100 and ends at the end of the energy dissipation section 110. In this way, the entire deep water wave current simulation pool can be divided into a plurality of deep water wave current simulation tanks for use.

[0047] Experimental data analysis:

[0048] 1. Analysis of water flow field simulation effect:

[0049] 1. The effect of the increase of the diversion cutter 400 in the rectifying section on the vertical water flow velocity distribution in the pool

[0050] In natural oceans or rivers, the flow velocity is generally logarithmically distributed in the vertical direction, and is calculated using the following formula:

[0051]

[0052] The vertical distribution of flow velocity is shown in the Appendix of this manual. Figure 5 shown.

[0053] This manual is attached Figure 6 The effect comparison of a typical water pool with and without the water flow simulation technology provided by the present invention is shown. It can be seen that when the water flow simulation technology provided by the present invention is not added, the flow velocity at the bottom of the water pool is large and that at the top is small, which is inconsistent with the actual situation and cannot meet the test requirements. After the water flow provided by the present invention is used, the water flow at different positions from the inlet is vertically large at the top and small at the bottom, which is basically in a logarithmic distribution form, which is consistent with the vertical distribution of the actual ocean or river flow velocity.

[0054] 2. The influence of energy dissipation section on the plane velocity distribution of water flow in the pool

[0055] Currently, the existing water pool does not have a water flow energy dissipation device, which causes the water flow to be mainly concentrated in the middle. The flow velocity in the middle is too high, while the flow velocity on both sides is very small, which cannot meet the test requirements. After adopting the rectifier provided by the present invention, the flow velocity across the entire water pool width is very uniform, which can meet the test requirements.

[0056] 2. Wave simulation effect

[0057] When using the existing common wave elimination device, the residual energy of the wave cannot be completely eliminated and reflects back and forth in the pool. Due to the influence of the superposition of the incident wave and the reflected wave, the measured wave surface is unstable, the wave height is uneven and very chaotic, and the result is distorted and cannot meet the test requirements. After using the efficient device provided by the present invention, the residual energy of the wave at the tail end of the pool can be effectively absorbed, the wave surface is stable, the wave height is uniform, and the test requirements are met.

[0058] How it works:

[0059] The present invention provides a circulation method for test water, which is applied in a simulated water pool. The original method of circulating water in the entire water pool through a large return water corridor is changed to a method of circulating water through a number of evenly distributed circulating waterways. This circulation method avoids the uneven water flow caused by the water in the return water corridor pouring into the simulated water pool with a large width from the corridor with a narrow diameter. At the same time, a good water flow state can also be guaranteed at the edge of the water pool. In addition, the flow-making device 600 will adopt a method of correspondingly setting the water inlet and the water outlet, and a corresponding group of water inlets and water outlets and a circulation pipe constitute a group of circulating waterways. The water is pumped out from the end of the water pool by the circulating water pump 640 and flows in from the front end, ensuring that the water flow direction of the entire water pool flows from the first section of the water pool to the end of the water pool, better simulating the marine dynamic environment.

[0060] After the test water enters from the water inlet, it passes through the energy dissipation section 110, the rectifying section 120, the experimental section 130, the wave dissipation section 140 and the outflow section 150 in the pool. The energy dissipation device includes a type of energy dissipation column 210 distributed in an array and a type of energy dissipation column 220 arranged at the tail end of the energy dissipation section 110. The cross section of the type of energy dissipation column 210 is circular, and the array distribution shape helps to disperse the water flow that gushes violently from the water inlet. The type of energy dissipation column 220 is streamlined, with a large front end width, and the width gradually decreases when transitioning to the tail end, which helps to guide the dispersed water flow. The water flow reduces the degree of turbulence through the energy dissipation device, meeting the needs of water flow simulation in model tests. The rectifying device includes a guide plate 300 and a flow cutter 400. The guide plate 300 is arranged in the middle of the pool body 100, and a wave maker 700 is arranged on the top of the guide plate 300. The wave maker 700 can drive the water body movement in the upper layer of the pool to generate periodic waves, simulating the real state that the ocean waves are mainly generated on the surface. In addition, a flow cutter 400 is also arranged at the tail end of the rectifying section 120, and the flow cutter 400 can guide the water flow to flow upward, ensuring that the real situation of the water flow velocity in the upper layer and the lower layer in the actual ocean is restored in the experimental section 130. A wave-breaking plate is arranged at the tail end of the experimental section 130, and the wave-breaking plate is arranged obliquely. When the water waves enter the wave-breaking plate, they first pass through the upper orifice plate 510 at the top. The holes of the upper orifice plate 510 are conducive to dispersing the water flow. A curved water flow channel is arranged in the water filter plate 520 in the middle layer. After the water flow enters the curved channel, the energy is gradually dissipated, and finally it flows out through the lower orifice plate 530 to reduce the residual energy of the wave.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
