Technical Field

[0002] Various experimental equipment and instruments are used to measure various physical parameters characterizing the flow of water or other liquids and their interaction with solid boundaries, and the measurement results are analyzed and data processed to study the relationships between various parameters.

[0003] The ship model is placed in the test water area, and by artificially controlling the flow of the water area, the effect of simulating water waves or water ripples is achieved, so that they impact on the ship, and then the impact data is collected and detected.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0024] Example 1: A multi-directional clamping device for a ship hydrodynamic test model, such as Figures 1-4 As shown, it includes a detection pool 1 and a limit frame 4 located on the opposite sides of the inner wall of the detection pool 1, the two limit frames 4 are simultaneously plugged with support columns 2, and a number of support blocks 3 are arranged between the two limit frames 4, the support blocks 3 are plugged with the support columns 2, and the upper ends of the support blocks 3 are screwed together with an adjusting rod 301, the adjusting rod 301 extends to the bottom of the support block 3, and the lower end of the adjusting rod 301 is installed with a rotating frame 304, the rotating frame 304 is rotatably connected to the rotating rod 305, the lower end of the rotating rod 305 is screwed together with a fastening nut 307, and a clamping support plate 306 is rotatably provided above the fastening nut 307. When the device is used, the position of the support column 2 is first limited under the limit of the limit frames 4 on both sides so that it is stably located inside the detection pool 1, and then By rotating the fastening nut 307, the clamping support plate 306 can be rotated to adjust the direction, and the side shape of the clamping support plate 306 can be adjusted as needed to enable targeted clamping. Then, the fastening nut 307 is rotated in the opposite direction to limit the position of the clamping support plate 306 on the rotating rod 305. Then, by adjusting the length of the adjusting rod 301, the angle of the rotating rod 305 is adjusted, so that the clamping support plates 306 at different positions are rotated at different angles. Then, with the combined use of the adjusting rod 301, multiple clamping support plates 306 provide support in different directions and angles, so that the device can provide clamping support at multiple angles, ensuring that fastening support can be provided when facing water waves in different directions during the experiment.

[0025] As Figures 1-4 shown, positioning cylinders 308 are installed on both opposite sides of the support block 3. The positioning cylinders 308 are inserted into the support columns 2, and a positioning nut 309 is screwed onto both the positioning cylinder 308 and the support column 2 at the same time. The positioning nut 309 includes a fastening cylinder connected to the outer side of the positioning cylinder 308 and a rotating cylinder connected to the outer side of the support column 2. With the rotational support of the positioning nut 309, the positioning cylinder 308 and the support column 2 can be firmly connected at the same time, thereby improving the connection stability between the positioning cylinder 308 and the support column 2 and ensuring the stability of the position of the support block 3 at the same time.

[0026] As Figures 1-4 shown, nuts for position fastening are installed on the outer side of the adjusting rod 301. The support block 3 is snap-connected with a limiting plate 302. A rotating snap ring 303 is rotatably arranged inside the limiting plate 302. Among them, the rotating snap ring 303 is snap-connected with the nut. With the limitation of the two adjusting rods 301 and the nut by the limiting plate 302, the position stability of the two adjusting rods 301 during support is ensured, and at the same time, with the rotational support of the rotating snap ring 303, the accuracy of the position when the rotating snap ring 303 is snap-connected with the nut is ensured.

[0027] Embodiment 2: A multi-directional clamping device for a ship hydrodynamic test model. As Figures 1-4 shown, there are at least two adjusting rods 301, and the support column 2 is located between the two adjusting rods 301. A support groove is provided on the upper surface of the rotating rod 305, and the rotating frame 304 is rotatably arranged inside the support groove. By adjusting the position of one of the adjusting rods 301, the angle of the rotating rod 305 can be adjusted, achieving the effect of adjusting the angle of the device below, making it more fitting when clamping at different angles.

[0028] As Figures 1-4 shown, nuts are provided on both opposite sides of the limiting frame 4. The two limiting frames 4 are used for limiting the support column 2. By limiting the limiting frame 4, the position stability of the support column 2 is ensured, and the stability of the operation of the clamping components thereon is improved.

[0029] Working principle: First, under the limitation of the limiting frames 4 on both sides, the position of the support column 2 is limited so that it is stably located inside the detection water pool 1, and then the fastening nut 307 is rotated to adjust the direction of the clamping support plate 306, and the side shape of the clamping support plate 306 is adjusted as needed so that it can be clamped in a targeted manner, and then the fastening nut 307 is rotated in the opposite direction to limit the position of the clamping support plate 306 on the rotating rod 305, and then the length of the adjusting rod 301 is adjusted to achieve the effect of adjusting the angle of the rotating rod 305, so that the clamping support plates 306 at different positions are rotated at different angles, and then with the combined use of the adjusting rod 301, multiple clamping support plates 306 provide support in different directions and angles, so that the device can provide clamping support at multiple angles.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
