Figure 3 ​​As shown in some embodiments, the driving part 24 can include two driving members, i.e. a third driving member 241 and a fourth driving member 242. The third driving member 241 and the fourth driving member 242 can be connected with the two transmission members 23 respectively to drive the two transmission members 23 to move respectively.

[0037] As shown in some embodiments, Figure 3 and Figure 4 As shown in some embodiments, the spraying part 2 can further include multiple pairs of assembling frames 26. The multiple pairs of assembling frames 26 can be distributed at intervals along the direction perpendicular to the spraying pipe 21.

The liquid is sprayed back to the test cavity 11 by the multiple spraying pipes 21, so that the stability of the liquid in the test cavity 11 can be ensured.

[0040] Further, as shown in some embodiments, Figure 3 and Figure 4As shown, the circulation channel 28 can include a water pump 281, a water suction pipe 282, a liquid supply pipe 283, a liquid distribution pipe 284, and a connecting hose 285.

[0041] As shown in FIG. 4, the water pump 281 has an input end fixedly connected to the water suction pipe 282 extending through the bottom of the test cavity 11. The water pump 281 has an output end fixedly connected to the liquid supply pipe 283 extending through the top of the test cavity 11 from the top of the main body 1. The end of the liquid supply pipe 283 is fixedly connected to the liquid distribution pipe 284. The pipes are connected by the connecting hose 285.

[0042] As shown in FIG. 4, the water pump 281 has an input end fixedly connected to the water suction pipe 282 extending through the bottom of the test cavity 11. The water pump 281 has an output end fixedly connected to the liquid supply pipe 283 extending through the top of the test cavity 11 from the top of the main body 1. The end of the liquid supply pipe 283 is fixedly connected to the liquid distribution pipe 284. The pipes are connected by the connecting hose 285.

Figure 2 As shown in FIG. 4, the water pump 281 has an input end fixedly connected to the water suction pipe 282 extending through the bottom of the test cavity 11. The water pump 281 has an output end fixedly connected to the liquid supply pipe 283 extending through the top of the test cavity 11 from the top of the main body 1. The end of the liquid supply pipe 283 is fixedly connected to the liquid distribution pipe 284. The pipes are connected by the connecting hose 285.

[0043] Further, based on the changes in the natural environment, the fluctuation amplitude of the water wave is different. By setting the wave pushing part 3, the liquid can be fluctuated in the first fluctuation mode to simulate the water wave with a larger fluctuation amplitude or in the second fluctuation mode to simulate the water wave with a smaller fluctuation amplitude, thereby achieving the purpose of more accurately testing the seakeeping performance of the ship model.

[0044] As shown in FIG. 4, the water pump 281 has an input end fixedly connected to the water suction pipe 282 extending through the bottom of the test cavity 11. The water pump 281 has an output end fixedly connected to the liquid supply pipe 283 extending through the top of the test cavity 11 from the top of the main body 1. The end of the liquid supply pipe 283 is fixedly connected to the liquid distribution pipe 284. The pipes are connected by the connecting hose 285. The liquid at the bottom of the test cavity 11 is supplied into the spray pipe 21 by the water pump 281 through the water suction pipe 282, the liquid supply pipe 283, the liquid distribution pipe 284, and the connecting hose 285 in sequence, and the nozzles 211 at the bottom of the spray pipe 21 spray the liquid downward. Figure 2As shown, in some embodiments, the wave-pushing section 3 includes a first wave-pushing assembly 31 and a second wave-pushing assembly 32. Both the first wave-pushing assembly 31 and the second wave-pushing assembly 32 may include a push plate and a driving member. The push plate may be at least partially located within the liquid and vertically disposed within the test chamber 11. The driving member may be connected to the push plate. The driving member can be used to push the push plate to move horizontally, thereby causing the liquid to ripple. The driving member may be a cylinder, a hydraulic cylinder, a robotic arm assembly, etc. The area of ​​the push plate in the first wave-pushing assembly 31 may be larger than the area of ​​the push plate in the second wave-pushing assembly 32.

[0045] Furthermore, the first wave-pushing assembly 31 may include a first pusher plate 311 and a first drive member 312. The second wave-pushing assembly 32 may include a second pusher plate 321 and a second drive member 322. The surface area of ​​the first pusher plate 311 may be larger than that of the second pusher plate 321, thereby simulating water waves with larger amplitudes when the first pusher plate 311 moves. When only the second pusher plate 321 moves, water waves with smaller amplitudes can be simulated. For example, in the first wave mode, both the second pusher plate 321 and the first pusher plate 311 move. In the second wave mode, the second pusher plate 321 moves, while the first pusher plate 311 remains stationary. Since the area of ​​the first pusher plate 311 is larger, two first drive members 312 can be provided to push the first pusher plate 311.

[0046] Furthermore, the first drive component 312 and the second drive component 322 can be cylinders, hydraulic cylinders, robotic arm assemblies, etc. When the first drive component 312 and the second drive component 322 are cylinders, the cylinders can be connected to an external air pump. By controlling the extension length and extension speed of the cylinders using the external air pump, the moving distance and moving speed of the second push plate 321 and the first push plate 311 can be controlled, thereby adjusting the fluctuation amplitude. Furthermore, the integrated controller 5 can be electrically connected to the external air pump to control the opening and closing of the external air pump.

[0047] In some embodiments, the driving member of the first wave-pushing assembly 31 can be connected to the pusher plate of the second wave-pushing assembly 32 through the pusher plate of the first wave-pushing assembly 31. Specifically, as... Figure 2 As shown, the second drive member 322 passes through the first pusher plate 311 and connects to the second pusher plate 321. The projection of the second pusher plate 321 onto the first pusher plate 311 can fall completely within the first pusher plate 311, thereby reducing the area of ​​the wave-pushing part 3. Furthermore, by adjusting the movement frequency of the second pusher plate 321 and the first pusher plate 311, the wave amplitude can be adjusted, thereby simulating the water waves during actual ship navigation more accurately.

[0048] like Figure 2As shown, in some embodiments, two symmetrically arranged wave-pushing parts 3 are provided, that is, the two wave-pushing parts 3 can be symmetrically arranged on both sides of the test cavity 11, thereby improving the uniformity of liquid fluctuation.

[0049] Figure 5 A perspective view schematically illustrates another state of the navigation test apparatus for a ship model according to an embodiment of the present invention.

[0050] like Figures 1-5 As shown, in some embodiments, the navigation test apparatus may further include multiple air blowing sections 4. These multiple air blowing sections 4 may be respectively disposed on different side walls of the main body 1. The air blowing sections 4 can be used to blow air into the test chamber 11 from multiple directions to simulate the wind environment encountered by the ship during actual navigation, thereby achieving the purpose of conducting a more accurate wind resistance test on the ship model.

[0051] Furthermore, such as Figure 5 As shown, each air-blowing part 4 may include a mounting slot 41, a mounting housing 42, a fan 43, and a drive motor 44. Multiple mounting slots 41 are respectively formed on each side wall of the main body 1. Each mounting slot 41 may be surrounded by a mounting housing 42. A fan 43 is rotatably connected within the mounting housing 42. A drive motor 44 is embedded in the side wall of the mounting housing 42. The output end of the drive motor 44 is fixedly connected to the end of the fan 43 via a coupling. The drive motor 44 can drive the fan 43 to rotate within the mounting housing 42, thereby adjusting the airflow direction of the fan 43. Both the fan 43 and the drive motor 44 are electrically connected to an external power supply and an integrated controller 5. The integrated controller 5 can control the rotation of the drive motor 44, thereby controlling the airflow direction of the fan 43, to achieve a more accurate wind resistance test of the ship model.

[0052] like Figure 1 As shown, in some embodiments, an opening 12 for retrieving the ship model is provided on the side wall of the main body 1. A slide rail 13 is provided around the opening 12. A switch door 14 is slidably connected inside the slide rail 13. The opening 12 can be opened or closed by pushing the switch door 14. After the switch door 14 is closed, the test chamber 11 can be made into a relatively sealed environment, preventing water generated during the test from splashing into the surrounding environment, thereby affecting the test personnel's observation of the ship model's various performance characteristics during the test.

[0053] like Figure 1 As shown, furthermore, an observation window 15 can be provided on the side wall of the main body 1. The observation window 15 can be made of explosion-proof tempered glass. By providing the observation window 15, the convenience for testers to observe the model during the test can be improved.

[0054] likeFigure 1 As shown, in some embodiments, a liquid level mark 16 is provided on the side wall of the test chamber 11. The liquid level mark 16 can be used to indicate the liquid level in the test chamber 11, and the ship model can be tested when the liquid reaches the liquid level mark 16.

[0055] like Figure 4 As shown, a drain pipe 17 extending into the test chamber 11 is provided on the side wall of the main body 1. The drain pipe 17 is connected to a switch valve 18. The drain pipe 17 can be used to discharge the liquid in the test chamber 11 after the test is completed. The switch valve 18 can be a solenoid valve. The switch valve 18 can be electrically connected to an external power supply and an integrated controller 5.
