DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problem of how to conduct an underwater vehicle surfacing test under the influence of water flow, the present invention provides a vehicle surfacing test device in a water flow environment, which can make the vehicle model be impacted by the water flow during the surfacing process, so as to study the influence of the water flow on the surfacing trajectory of the underwater vehicle.

[0020] It should be noted that the vehicle floating test device in a water flow environment of the present invention is used for underwater vehicle floating test. For the convenience of explanation, in the present invention, the vehicle floating test device in a water flow environment is explained as being applied to underwater vehicle floating test.

[0021] See also Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle floating test device in a water flow environment in one embodiment of the present invention. The vehicle floating test device in a water flow environment includes a pool body 100, an anchoring assembly 200 and a flow-making assembly 300. The pool body 100 is used to store water. The anchoring assembly 200 has an anchoring end arranged inside the pool body 100. The anchoring end has a first state for fixing the vehicle model and a second state for releasing the vehicle model. The flow-making assembly 300 includes a pumping end and a drainage end connected to both ends of the pool body 100. The pumping end is used for pumping water, and the drainage end is used for drainage, so that a water flow is formed in the pool body 100.

[0022] During use, the device for testing vehicle buoyancy in a water flow environment provided by the present invention requires adjusting the anchor end to a first position, thereby securing the vehicle model. The anchor end is then adjusted to a second position, allowing the vehicle model to detach from the anchor end and float. During the buoyancy process, the pumping end of the flow-generating assembly 300 pumps water, while the drain end drains water, thereby generating a water flow within the tank 100. This allows the vehicle model to be affected by the water flow during the buoyancy process, enabling research into the influence of the water flow on the buoyancy trajectory of the underwater vehicle.

[0023] In some embodiments, the pumping end has several pumping positions, each of which can be opened or closed for pumping, and the draining end has several draining positions, each of which can be opened or closed for draining. In the above embodiments, water is drawn from the pool body 100 through the various pumping positions and returned to the pool body 100 through the various draining ends, thereby forming a water flow within the pool body 100. It will be appreciated that the relative positions of the various pumping positions and draining positions determine the direction of the water flow within the pool body 100. For example, if the various opened draining positions are higher than the various opened pumping positions, a downward sloping water flow will be formed within the pool body 100. If the various opened draining positions and the various opened pumping positions are at the same height, a horizontal water flow will be formed within the pool body 100. Experimenters can adjust the opening and closing states of the various pumping and draining positions, thereby adjusting the relative positions of the opened draining and opened pumping positions.

[0024] Based on the above embodiments, in some of the embodiments, one end of the pool body 100 is provided with a plurality of pumping ports 110 and a plurality of pumping valves 120 corresponding to a plurality of pumping positions. The pumping end is connected to the plurality of pumping ports 110, and the pumping valves 120 are installed at the pumping ports 110 to control the opening and closing of the pumping ports 110. The other end of the pool body 100 is provided with a plurality of drain ports 130 and a drain valve 140 corresponding to a plurality of drain positions. The drain end is connected to the plurality of drain ports 130, and the drain valve 140 is installed at the drain port 130 to control the opening and closing of the drain port 130. Each pumping port 110 corresponds to a pumping position, and the opening and closing state of the pumping position can be changed by controlling the opening and closing of the pumping port 110 through the pumping valve 120. Similarly, each drain port 130 corresponds to a draining position, and the opening and closing state of the draining position can be changed by controlling the opening and closing of the drain port 130 through the drain valve 140.

[0025] In some embodiments, the water inlet 110 is in the form of a horizontally extending strip, with multiple water inlets 110 arranged in a vertical sequence. The water outlet 130 is in the form of a horizontally extending strip, with multiple water outlets 130 arranged in a vertical sequence. The water flow patterns at the water inlet 110 and the water outlet 130 affect the water flow patterns within the pool body 100. Specifically, the width of the water inlet 110 and the water outlet 130 determines the width of the affected water flow. Since both the water inlet 110 and the water outlet 130 are in the form of horizontally extending strips, the range affected by the water flow can be expanded.

[0026] In some embodiments, the water pump valve 120 includes a first flap 121 and a first driving unit 122. The first flap 121 is rotatably mounted on the water pump port 110. The first driving unit 122 is in transmission connection with the first flap 121 and drives the first flap 121 to rotate to open or close the water pump port 110. The water discharge valve 140 includes a second flap 141 and a second driving unit 142. The second flap 141 is rotatably mounted on the water discharge port 130. The second driving unit 142 is in transmission connection with the second flap 141 and drives the second flap 141 to rotate to open or close the water discharge port 130. The first driving unit 122 drives the first flap 121 to rotate. When the first flap 121 is in close contact with the water pump port 110, it can close the water pump port 110, preventing water from flowing through the water pump port 110. When the first flap 121 is away from the water pump port 110, it can open the water pump port 110, allowing water to flow through the water pump port 110. Similarly, the second driving unit 142 drives the second flap 141 to flip. When the second flap 141 is close to the drain outlet 130, the drain outlet 130 is closed, preventing water from flowing through the drain outlet 130. When the second flap 141 is away from the drain outlet 130, the drain outlet 130 is opened, allowing water to flow through the drain outlet 130.

[0027] It is understood that any embodiment of the first driving unit 122 is feasible as long as it can drive the first flap 121 to flip. For example, the first driving unit 122 can be a flip hydraulic cylinder connected to the pivot of the first flap 121, thereby driving the first flap 121 to flip. Similarly, any embodiment of the second driving unit 142 is feasible as long as it can drive the second flap 141 to flip. For example, the second driving unit 142 can also be a flip hydraulic cylinder connected to the pivot of the second flap 141, thereby driving the second flap 141 to flip.

[0028] Any embodiment of the flow-generating assembly 300 is feasible as long as it can extract water from the pool body 100 and pressurize the water back to the pool body 100. In some embodiments, the flow-generating assembly 300 includes a water pump 310, a first pipe 320, and a second pipe 330. The first pipe 320 has two ends connecting the pumping end and the water pump 310, respectively, and the second pipe 330 has two ends connecting the water pump 310 and the drainage end, respectively. The water pump 310 extracts water from the pool body 100 through the first pipe 320, and the water extracted by the water pump 310 is pressurized back to the pool body 100 through the second pipe 330.

[0029] In some embodiments, based on the above embodiments, the flow-generating assembly 300 further includes a first diverter cover 340 and a second diverter cover 350. The first pipe 320 is connected to the pumping end via the first diverter cover 340, and the second pipe 330 is connected to the drainage end via the second diverter cover 350. Water drawn from the pumping end enters the first diverter cover 340, and then is pressured back to the drainage end through the first pipe 320, the water pump 310, the second pipe 330, and the second diverter cover 350. The first diverter cover 340 can connect the larger water flow area of ​​the pumping end to the smaller water flow area of ​​the first pipe 320. The second diverter cover 350 can connect the smaller water flow area of ​​the drainage end to the larger water flow area of ​​the drainage end.

[0030] In some embodiments, the apparatus for testing the buoyancy of an underwater vehicle in a water flow environment further includes a wave-making assembly 400, which includes a bracket 410, a wave-making block 420, and a lifting drive 430. The bracket 410 is built into the pool body 100, and the wave-making block 420 is vertically slidably disposed on the bracket 410. The lifting drive 430 is transmission-connected to the wave-making block 420, which drives the wave-making block 420 to slide along the bracket 410, thereby generating waves through the sliding wave-making block 420. By driving the wave-making block 420 to slide on the bracket 410 through the lifting drive 430, and using the wave-making block 420 to push the water flow to generate waves, an environment affected by waves can be simulated, so as to facilitate the study of the influence of waves on the buoyancy trajectory of the underwater vehicle.

[0031] In some embodiments, the lifting drive member 430 includes a first guide wheel 431, a second guide wheel 432, a rope ring 433, and a driving motor 434. The first guide wheel 431 and the second guide wheel 432 are rotatably mounted on both ends of the bracket 410, respectively. The rope ring 433 surrounds the first guide wheel 431 and the second guide wheel 432 and is connected to the wave-making block 420. The driving motor 434 is connected to the first guide wheel 431 and / or the second guide wheel 432. The driving motor 434 drives the first guide wheel 431 and / or the second guide wheel 432 to rotate, thereby driving the rope ring 433 to rotate. The rotating rope ring 433 can then drag the wave-making block 420 to move, thereby generating waves through the moving wave-making block 420.

[0032] In some other embodiments, the bottom end of the wave-making block 420 has an inclined guide wedge surface, which can guide the water flow. Under the guidance of the guide wedge surface, the water flow pushed by the wave-making block 420 has a clear flow direction, thereby making the waves excited by the wave-making block 420 more controllable.

[0033] Any embodiment of the anchor assembly 200 is feasible as long as it can release and secure the aircraft model. For example, the anchor assembly 200 may employ a clamping claw or snap-on structure. When the aircraft model needs to be secured, the clamping claw or snap-on structure can be used to attach the aircraft model. When the aircraft model needs to be released, the clamping claw or snap-on structure can be released from the aircraft model. In some embodiments, the anchor assembly 200 includes a base 210 and an electromagnet 220. The base 210 is mounted to the bottom of the tank body 100. The electromagnet 220 is mounted to the base 210. The electromagnet 220 has an anchoring end. The electromagnet 220 has a magnetic force that attracts the aircraft model. The magnetic force of the electromagnet 220 can be adjusted to switch the anchoring end between a first state and a second state. When the aircraft model needs to be secured, the electromagnet 220 can be attracted to the aircraft model. When the aircraft model needs to be released, the electromagnet 220 can be demagnetized, allowing the aircraft model to be released from the electromagnet 220.

[0034] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the present invention is described in detail: During use, the device for testing vehicle buoyancy in a water flow environment requires adjusting the anchor end to a first position, allowing the electromagnet 220 to attract and secure the vehicle model. Subsequently, the anchor end is adjusted to a second position, demagnetizing the electromagnet 220, allowing the vehicle model to detach from the electromagnet 220 and float. During the buoyancy process, the water pump 310 draws water from the tank 100 via the first pipe 320 and pumps the pumped water back into the tank 100 via the second pipe 330, thereby creating a water flow within the tank 100. This allows the vehicle model to be affected by the water flow during its buoyancy, allowing for the study of its influence on the buoyancy trajectory of the underwater vehicle. Furthermore, the wave-generating block 420 can be driven to slide on the bracket 410 by the lifting drive 430. This wave-generating block 420 propels the water flow, generating waves. This simulates a wave-affected environment, facilitating the study of its influence on the buoyancy trajectory of the underwater vehicle.
