Description

Technical Field

[0001] The utility model relates to the technical field of wave simulation experiments, in particular to a wind wave water tank test system. Background Art

[0002] In the field of marine engineering, wind and waves are an important consideration. The action of wind and waves can bring loads and vibrations to marine engineering structures, leading to fatigue damage and safety issues.

[0003] In 1925, British scientist Jeffreys used a wind and wave tank to simulate the mechanism of wind and wave generation, realizing the study of wind and wave characteristics in the laboratory. Later, many countries also used large-scale wind and wave tanks to simulate the generation and development of wind and waves, and achieved similar relationships between wind and wave elements in the laboratory and on the actual ocean, such as the similarity of wind and wave spectra and the similarity of the logarithmic distribution of wind speed on the water surface. The model law was derived, and the simulation results were used for research on wind and wave forecasting, the transport of sediment by coastal waves, and the force of wind and waves on hydraulic structures.

[0004] However, most of the existing wind and wave tanks are designed for medium and large scales, which require high construction investment and maintenance costs, have complex structures, and cannot arbitrarily change experimental plans and parameters during experiments, resulting in high experimental costs.

[0038] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0040] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0041] like Figures 1 to 4 As shown in FIG, it is a schematic diagram of the wind wave water tank test system provided by the present invention, including a water tank body 11 and a control system. Figure 1-3 FIG. 1 is a schematic diagram of the structure of the water tank body 11. A wind wave generating component 22 is provided at the end of the water tank body 11. The wind wave generating component 22 can generate wind waves to generate wind waves within the water tank body 11. A control system is electrically connected to the wind wave generating component 22 to control the size of the wind waves generated by the wind wave generating component 22.

[0042] The water tank body 11 is an elongated trough structure with an open top and baffles 111 arranged at the bottom and around the sides. The length is 4-8 meters, which is suitable for placement in a small laboratory and does not take up too much space. A support frame 112 is arranged around the baffle 111, which supports the baffle 111 on the lower surface and the sides. The support frame 112 is a frame structure composed of a number of rods. A fixed block is provided at the bottom of the water tank body 11, and the water tank body 11 is leveled or fixed by the fixed block. The fixed block is not shown in the figure. Specifically, the fixed block generally adopts a flange, half of the flange is fixed on the support frame 112, and the other half is exposed and connected to a boss with a threaded substructure. The boss is used to tighten the water tank body 11 by rotating the thread, supporting the water tank body 11 from the bottom and squeezing the water tank body 11 from all sides, so as to achieve the purpose of leveling and fixing the water tank body 11.

[0043] The tail end of the water tank body 11 is provided with an energy dissipation device to eliminate the energy of the incoming wave wake as much as possible and to reduce the reflected wave energy as much as possible. The baffle 111 is made of a transparent material, preferably transparent PVC, to facilitate observation of wave generation; the baffles 111 are connected with glass glue to prevent water leakage in the water tank body 11. The support frame 112 and the fixing block are made of metal material, preferably stainless steel. The end of the support frame 112 that contacts the ground is also provided with a fixing plate, which is fixed to the ground by the fixing plate, and the fixing method can be a threaded connection.

[0044] More specifically, the upper opening of the water tank body 11 can be sealed with a cover to isolate the water surface airflow in the water tank body 11 from the outside world, so as to generate forced wind waves similar to those in nature. At the same time, an outlet is left at the tail of the water tank to prevent backflow of the wind field.

[0045] The wind-wave-generating component 22 is fixed to the water tank body 11 via a housing assembly 33. The housing assembly 33 is surrounded by six baffles, including side baffles 331, an upper baffle 332, a back baffle 333, an inclined baffle 334, and a bottom baffle 335. This arrangement prevents external wind from affecting the wind field generated by the wind-wave-generating component 22. It also prevents the wind field generated by the wind-wave-generating component 22 from being dispersed at various angles, thereby protecting the wind field generated by the wind-wave-generating component 22. Furthermore, based on the position of the fan assembly, a through hole is provided on one side of the baffle, allowing the fan assembly's air inlet to face it, facilitating air intake. The bottom baffle 335 is vertically penetrated by a through hole, which is positioned opposite the air guide grille 224 to facilitate the wind-wave-generating component 22 in blowing wind into the water tank body 11, forming wind waves. The inclined baffle 334 is located above the air outlet and is set to an inclined state. Its main function is to guide the wind to blow obliquely on the water surface to generate wind waves. The installation angle of the inclined baffle 334 can be adjusted according to the nature of the wind waves to be generated. When the inclination angle is large, the wind enters the water to a large depth, the wave amplitude is large, and the period is short; when the inclination angle is small, the wind enters the water to a small depth, the wave amplitude is small, and the period is long.

[0046] The wind wave generating component 22 includes a fan assembly and a wind guide assembly. The fan assembly is connected to the wind guide assembly, which opens toward the water tank body 11 and is used to create a wind field environment with a uniform wind pressure distribution. The fan assembly generates wind power according to the control system settings and transmits this wind power to the wind guide assembly, which blows the wind waves into the water tank body 11, forming wind waves.

[0047] The fan assembly includes an air inlet, a motor 221, an impeller, and an air outlet. The motor 221 is fixed to the side baffle 331 of the housing assembly. The impeller is mounted on the motor 221, which is provided with an impeller housing 222. The impeller housing 222 has an air inlet located at the center of the impeller and aligns with the through-hole in the housing assembly. The opening of the impeller housing 222, facing the bottom baffle 335, serves as the air outlet. During operation, the motor 221 rotates, driving the impeller to rotate, drawing air in through the air inlet and blowing it out through the air outlet.

[0048] The wind guide assembly includes a wind guide duct 223 and a wind guide grid 224. One end of the wind guide duct 223 is connected to the air outlet, and the other end is connected to the wind guide grid 224. The wind guide grid 224 faces the bottom baffle 335 and is opposite the tank body 11. It is used to create a wind field environment with a constant wind pressure distribution, so that the wind field cross-section of the guided wind wave has a constant wind pressure distribution. It is worth noting that the wind guide grid 224 can be configured with different cross-sectional shapes as required, such as circular, rectangular, or irregular. In this embodiment, an elliptical shape is preferred.

[0049] The control system, not shown in the diagram, primarily includes a motor driver and power supply. The motor driver is electrically connected to motor 221 and the power supply. The motor driver drives motor 221 in response to received commands, thereby rotating the impeller. The motor driver can adjust the rotational speed to control the amount of wind generated. It is worth noting that motor 221 is a high-power servo motor, such as an ECMA-C20807RS servo motor. The motor driver can utilize an ASD-B2-0721-B motor driver. The power supply output voltage is 24V.

[0050] The power supply is electrically connected to the motor driver and the motor 221 and is mainly used to provide electrical energy thereto.

[0051] During operation, water is filled in the water tank, and the motor driver drives the motor 221 to achieve a given rotation speed according to a given rotation speed and number of rotations, thereby driving the impeller to inhale air from the air inlet and output it from the air outlet into the air guide duct 223, and then transported to the air guide grid 224, forming wind waves with equal pressure distribution to blow on the water surface and generate wind waves.

[0052] It can be understood that a wind wave water tank is a device that generates waves on the water surface by utilizing wind power. The wind wave water tank of the utility model has the following characteristics:

[0053] 1. By adjusting the wind speed and setting different rotation frequencies and amplitudes, different waves can be generated. This technology can generate waves with specific characteristics to meet different research needs, simulating various complex wave environments. This provides important support for experimental research in fields such as marine engineering, wave resistance of structures, and wave energy utilization, and is suitable for different experimental needs or research purposes.

[0054] 2. Driven by a motor, it can generate waves stably and continuously, with stability and controllability.

[0055] 3. By setting the rotation frequency and amplitude, waves with the same characteristics can be repeatedly generated, which is of great significance for experimental comparison and result verification.

[0056] 4. The motor-driven method can precisely control the formation and propagation of waves, making it easier to study and observe waves.

[0057] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
