Description

Technical Field

[0001] The utility model relates to the technical field of navigation body testing, in particular to a system for testing a navigation body in a cross-media environment. Background Art

[0002] Trans-Media Aerial Underwater Vehicle (TMAUV) refers to a new type of vehicle that can autonomously and multiple times cross the water-air interface and can stably navigate in the water and fly in the air. This type of vehicle was first used in sea-skimming weapon platforms, using its underwater concealment and high speed and high maneuverability in the air to improve the weapon's penetration capability and attack success rate. In addition, trans-water-air unmanned vehicles can be used as cruise weapons for maritime reconnaissance or attack. Compared with traditional underwater single-media vehicles, their search capabilities have a qualitative leap. With the development of communication technology, trans-water-air medium vehicles have entered the field of civil engineering, including deep sea detection, water quality monitoring, maritime search and rescue, maritime communications, etc.

[0003] There are still some key issues in the research process of cross-media vehicles that need to be studied and solved in depth. In the process of crossing the water-air medium, the vehicle is affected by multiphase flow fields such as air, water, and cavitation. The change law of the time-varying force load of the vehicle is closely related to the multiphase complex flow phenomena around the vehicle. In order to design a controllable and stable cross-media vehicle, it is necessary to quantitatively measure and study the real-time change law of the aerodynamic force, hydrodynamic force and other force loads that the vehicle is subjected to during the cross-media process, especially the change of the medium around the vehicle, the formation, development and change of cavitation and other complex flow phenomena on this highly time-varying characteristic.

[0004] Cross-media water entry and exit involve complex multidisciplinary cross-disciplinary issues such as thermodynamic processes, material phase change processes, kinetic processes, impact dynamics processes, structural safety, material properties, motion control, etc. To conduct scaled-down tests, we must first study the similarity of the above characteristics. Currently, the most advanced decompression or low-pressure water tank test system for studying cross-media water entry and exit can achieve a certain degree of simulation and reproduction of prototype test phenomena in model tests on the basis of ensuring the similarity of cavitation numbers and Froude numbers.

[0014] In one embodiment, the system includes a mechanical claw, which is arranged on the top of the airtight water pool and is used to clamp the navigation object to be tested.

[0015] In one embodiment, the receiving platform includes a transfer platform, a lap joint platform and a water pool platform.

A second liquid level sensor is provided in the airtight water pool, and the second liquid level sensor is used to detect the water level of the airtight water pool.

[0021] Compared with the prior art, the utility model has the following advantages:

[0022] 1. The above-mentioned system for testing the navigation body is used to test the performance of the navigation body in a trans-water and air medium. In order to improve the effectiveness of the test, a low-pressure water tank test system is adopted. First, an airtight water tank is established by combining a low-pressure space and a water body, so that the environment in the water tank maintains a low pressure, which is used to simulate the marine environment. Furthermore, in order to place the navigation body to be tested into the airtight water tank without destroying the low-pressure environment in the airtight water tank, a transition cabin connected to the airtight water tank is set up, so that the navigation body to be tested can enter the airtight water tank through the transition cabin and the inlet and outlet holes. The structure is simple and easy to use. At the same time, due to the provision of a transportation component, the navigation body to be tested can be loaded on the transportation component, and automatically enter and exit the airtight water tank without manual operation, thereby realizing precise transportation, and multiple tests can be carried out in a low-pressure environment for a long time, thereby improving the test efficiency.

[0023] 2. The transport component in the system is equipped with a load-bearing platform spanning the transition cabin and the airtight water pool, and a movable transport vehicle is arranged on the load-bearing platform. The vehicle to be tested is loaded on the transport vehicle, and the mobile transport vehicle can automatically move the vehicle to be tested into and out of the airtight water pool, which can effectively improve the degree of automation of the movement of the vehicle to be tested, thereby improving the transportation efficiency.

[0024] 3. For the test object with a cylindrical structure, a circular mounting hole can be set on the transport vehicle, and the test object can be loaded by inserting the test object into the mounting hole. The structure is simple and the loading efficiency is high. At the same time, a thruster can be set on the bottom wall of the mounting hole, so that the transport vehicle can also be used as a test catapult to set the initial test velocity for the test object, realizing the integration of the transport test structure.

[0025] 4. When the transport vehicle ejects the vehicle to be tested and conducts water in and out tests, the vehicle to be tested will randomly fall onto the carrying platform. The mechanical claw can grab the scattered vehicle to be tested on the carrying platform and load the vehicle to be tested onto the transport vehicle, making it easier for the transport vehicle to transport the vehicle to be tested out of the airtight water pool. Therefore, the mechanical claw improves the degree of automation of the performance test of the vehicle to be tested and improves the test efficiency.

[0026] 5. Furthermore, in order to simplify the installation and manufacturing process of the receiving platform, the receiving platform is divided into three independent parts: the transfer platform, the lap joint platform and the pool platform; and the transfer platform and the pool platform are both movable in the height direction. Therefore, when the test object is on the operating platform, the transfer platform can be raised with the transport vehicle to be flush with the operating platform, and the staff can load the test object on the transport vehicle here. After the loading is completed, the transfer platform is lowered with the transport vehicle to be flush with the lap joint platform. At this time, the transport vehicle carries the test object to the pool platform, and the pool platform moves with the transport vehicle to the test object. The initial test height of the test vehicle is such that after the test vehicle has undergone various test items at this height, the water pool platform moves with the transport vehicle to be flush with the docking platform, and the transport vehicle then transports the test vehicle to the transfer platform. The transfer platform rises to the operating platform, and the test vehicle is unloaded on the operating platform, thus completing the entire transportation and testing process of the test vehicle. It can be seen that the liftable transfer platform and water pool platform make it more convenient to load and unload the test vehicle on the transfer platform, and the initial test height on the water pool platform is more flexible, which effectively improves the test efficiency and scope of use of the system.

[0027] 6. A first displacement sensor is set on the transfer platform, and a second displacement sensor is set on the water pool platform to detect the vertical distances between the transfer platform, the water pool platform and the overlapping platform. This can ensure that the transfer platform is accurately aligned with the overlapping platform during the descent, and that the water pool platform is accurately aligned with the overlapping platform during the descent. Therefore, the transport vehicle moves more smoothly at the overlaps between the water pool platform and the overlapping platform, and between the transfer platform and the overlapping platform, thereby improving transportation efficiency.

[0028] 7. The slide rails on the receiving platform slide with the transport vehicle to fix the moving path of the transport vehicle, making the movement of the transport vehicle more controllable, facilitating the setting of automated drive control equipment, and improving transportation efficiency.

[0029] 8. The first liquid level sensor and the second liquid level sensor are used to detect the water level of the transition tank and the water level of the airtight water tank respectively, so as to monitor the water level of the transition tank and the water level of the airtight water tank at all times to ensure that the water level is at a safe height, and to judge the ambient air pressure in the airtight water tank by the water level difference between the water level of the transition tank and the water level of the airtight water tank.

DETAILED DESCRIPTION

[0033] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, a system 100 for testing a navigation body in a cross-media environment is provided, including an airtight water pool 10, a transition cabin 20, and a transport component 30;

[0035] Among them, the airtight water pool 10 is used to accommodate the water body 11 and the low-pressure environment 12. The side wall of the airtight water pool 10 is provided with an inlet and outlet hole 13, and the height of the inlet and outlet hole 13 is lower than the liquid level of the water body 11; the transition cabin 20 is arranged on one side of the airtight water pool 10, one end of the transition cabin 20 is connected with the inlet and outlet hole 13, and the other end of the transition cabin 20 is connected with the external environment; the transportation component 30 is provided with a navigation body mounting part for loading the navigation body 60 to be tested, and the transportation component 30 can move between the transition cabin 20 and the airtight water pool 10.

[0036] The low pressure environment 12 refers to an environment where the air pressure is lower than the normal atmospheric pressure.

[0037] The above-mentioned system 100 for testing the navigation body is used to test the performance of the navigation body in a trans-water-air medium. In order to improve the effectiveness of the test, a low-pressure water tank test system is adopted. First, the environment in the water tank is kept at a low pressure through the airtight water tank 10 and the water body 11. Furthermore, in order to place the navigation body 60 to be tested into the airtight water tank 10 without destroying the low-pressure environment 12 in the airtight water tank 10, a transition cabin 20 connected to the airtight water tank 10 is provided, so that the navigation body 60 to be tested can enter the airtight water tank 10 through the transition cabin 20 and the inlet and outlet holes 13. The structure is simple and easy to use. At the same time, due to the provision of a transportation component 30, the navigation body 60 to be tested can be loaded on the transportation component 30 to enter and exit the airtight water tank 10. Without the need for manual operation, the navigation body 60 to be tested can automatically enter and exit the airtight water tank, thereby realizing precise transportation, and multiple tests can be carried out in a long-term low-pressure environment, thereby improving the test efficiency.

[0038] Specifically, Figure 1 and Figure 2 As shown, in one embodiment, the transport component 30 includes a receiving platform 31 and a transport vehicle 32, the navigation body installation part is arranged on the transport vehicle 32, the receiving platform 31 passes through the inlet and outlet holes 13 and is respectively located in the transition cabin 20 and the airtight water pool 10, and the transport vehicle 32 is movably arranged on the receiving platform 31. The transport component 30 in the system is provided with a bearing platform spanning the transition cabin 20 and the airtight water pool 10, and a movable transport vehicle 32 is arranged on the bearing platform, the navigation body 60 to be tested is loaded on the transport vehicle 32, and the moving transport vehicle 32 can realize the movement of the navigation body 60 to be tested into and out of the airtight water pool 10, thereby effectively improving the movement efficiency of the navigation body 60 to be tested.

[0039] Furthermore, if Figure 2 As shown, in one embodiment, the measured navigation body 60 is a cylindrical structure, and the navigation body mounting member includes a mounting hole 321 provided on the transport vehicle 32 , and one end of the measured navigation body 60 can be inserted into the mounting hole 321 .

[0040] The vehicle mounting member may also include an elastic gripping clip disposed in the mounting hole 321 for fixing the vehicle 60 to be tested on the transport vehicle 32 .

[0041] Furthermore, in one embodiment, a propeller is provided between the bottom wall of the mounting hole 321 and the test vehicle 60, which is used to set the initial test velocity for the test vehicle 60. For the test vehicle 60 with a cylindrical structure, a circular mounting hole 321 can be provided on the transport vehicle 32, and the test vehicle 60 can be loaded by inserting the test vehicle 60 into the mounting hole 321, which has a simple structure and high loading efficiency. At the same time, a propeller can be provided on the bottom wall of the mounting hole 321, so that the transport vehicle 32 can also be used as a test catapult to set the initial test velocity for the test vehicle 60, thereby realizing the integration of the transport test structure.

[0042] In addition, the system includes a mechanical claw 50, which is arranged on the top of the airtight pool 10 and is used to clamp the test vehicle 60 located on the pool platform 313. When the transport vehicle 32 ejects the test vehicle 60 and performs the water in and out test, the test vehicle 60 will randomly fall on the carrying platform, and the mechanical claw 50 can grab the scattered test vehicle 60 on the carrying platform and load the test vehicle 60 on the transport vehicle 32, so that the transport vehicle 32 can subsequently transport the test vehicle 60 out of the airtight pool 10. Therefore, the mechanical claw 50 improves the automation of the performance test of the test vehicle 60 and improves the test efficiency.

[0043] Various stress sensors can be arranged on the tested navigation body 60 to test the stress changes and stability of various parts of the tested navigation body 60 by simulating the process of the tested navigation body 60 entering and exiting water.

[0044] Among them, the structure of the mechanical claw 50 is an existing mechanical claw structure, which is used to grasp the cylindrical surface of the navigation body 60 to be tested. In order to facilitate the mechanical claw 50 to grasp the navigation body 60 to be tested, a visual sensor 16 is also provided in the airtight water pool 10 to provide environmental information for the mechanical claw 50, so that the mechanical claw 50 can make decisions and perform corresponding operations. The visual sensor 16 is electrically connected to the mechanical claw 50. A grasping mark can be set on the circumferential surface of the navigation body 60 to be tested. The visual sensor 16 is used to identify the grasping mark. When the visual sensor 16 recognizes the grasping mark, the mechanical claw 50 is controlled to grasp the position of the grasping mark set on the circumferential surface of the navigation body 60 to be tested. The position of the transport vehicle 32 can also be identified by the visual sensor 16, and then the mechanical claw 50 is controlled to insert the clamped navigation body 60 to be tested into the installation hole 321. Of course, if the visual sensor 16 is not provided, the position of the mechanical claw 50 can also be manually controlled to grasp and load the navigation body 60 to be tested.

[0045] In this specific embodiment, an elastic pad can be set on the receiving platform 31, especially on the pool platform 313, to protect the receiving platform 31 or the pool platform 313, so as to prevent the receiving platform 31 or the pool platform 313 from being damaged after the test navigation body 60 is ejected.

[0046] Specifically, Figure 2 As shown, in one embodiment, the receiving platform 31 includes a transfer platform 311, a lap platform 312 and a pool platform 313. The transfer platform 311 is arranged in the transition cabin 20, the pool platform 313 is arranged in the airtight pool 10, and the lap platform 312 passes through the inlet and outlet holes 13 and is respectively lapped with the transfer platform 311 and the pool platform 313. In order to simplify the installation and manufacturing process of the receiving platform 31, the receiving platform 31 is divided into three independent parts: the transfer platform 311, the lap platform 312 and the pool platform 313.

[0047] Furthermore, if Figure 1As shown, in one embodiment, the system also includes an operating platform 40, the top of the transition cabin 20 is overlapped with the operating platform 40, and the transfer platform 311 can move up and down along the height direction of the transition cabin 20; the pool platform 313 can move up and down along the height direction of the pool, and is used to set the initial height for the navigation body 60 to be tested.

[0048] The transfer platform 311 and the pool platform 313 are both capable of moving in the height direction. Therefore, when the test object 60 is on the operating platform 40, the transfer platform 311 can be raised with the transport vehicle 32 to be flush with the operating platform 40, and the staff can load the test object 60 on the transport vehicle 32 here. After the loading is completed, the transfer platform 311 and the transport vehicle 32 are lowered to be flush with the lap platform 312. At this time, the transport vehicle 32 carries the test object 60 to the pool platform 313, and the pool platform 313 moves with the transport vehicle 32 to the initial test height of the test object 60. The test object 60 is tested at this height. After the test items are completed, the pool platform 313 moves with the transport vehicle 32 to be flush with the overlapping platform 312, and then the transport vehicle 32 transports the tested navigation body 60 to the transfer platform 311, and the transfer platform 311 rises to the operating platform 40, and the unloading of the tested navigation body 60 is completed on the operating platform 40, and finally the transportation and testing process of the entire tested navigation body 60 is completed; it can be seen that the liftable transfer platform 311 and the pool platform 313 make it more convenient to load and unload the tested navigation body 60 on the transfer platform 311, and the initial test height on the pool platform 313 is more flexible, which effectively improves the test efficiency and scope of use of the system.

[0049] The transfer platform 311 can be provided with a first winch and a first suspension rope 33 structure to achieve lifting, such as fixing the first winch on the operating platform 40, winding one end of the first suspension rope 33 on the winch, and connecting the other end of the first suspension rope 33 to the transfer platform 311, and the lifting of the transfer platform 311 is achieved by rotating the first winch. The pool platform 313 can also be provided with the same lifting structure, including a second winch and a second suspension rope 34, fixing the second winch in the airtight pool 10, and connecting the two ends of the second suspension rope 34 to the second winch and the pool platform 313, respectively, and the second winch rotates to lift the pool platform 313.

[0050] In addition, a horizontal inclination sensor 18 is provided in the airtight water pool 10 to detect the levelness of the water pool platform 313, so that the water pool platform 313 is flush with the overlapping platform 312, thereby improving the docking accuracy.

[0051] In another embodiment, the transfer platform 311 and the pool platform 313 can also be connected to the transition compartment 20 and the bottom of the pool by being set to rise by buoyancy and descend by cable tension, so as to achieve the lifting and lowering of the transfer platform 311 and the pool platform 313. As long as the transfer platform 311 and the pool platform 313 can be lifted and lowered smoothly, they will not be elaborated here.

[0052] Furthermore, if Figure 2 As shown, in one embodiment, a first displacement sensor 21 is provided on the transfer platform 311, and the first displacement sensor 21 is used to detect the vertical distance between the transfer platform 311 and the overlapping platform 312. A second displacement sensor 14 is provided on the pool platform 313, and the second displacement sensor 14 is used to detect the distance between the pool platform 313 and the overlapping platform 312.

[0053] A first displacement sensor 21 is arranged on the transfer platform 311, and a second displacement sensor 14 is arranged on the water pool platform 313 to detect the vertical distances among the transfer platform 311, the water pool platform 313 and the overlapping platform 312, so as to ensure that the transfer platform 311 is accurately aligned with the overlapping platform 312 during the descent, and ensure that the water pool platform 313 is accurately aligned with the overlapping platform 312 during the descent. Therefore, the transport vehicle 32 moves more smoothly at the overlapping parts between the water pool platform 313 and the overlapping platform 312 and between the transfer platform 311 and the overlapping platform 312, thereby improving the transportation efficiency.

[0054] Furthermore, if Figure 2 As shown, in one embodiment, a slide rail 314 is provided on the receiving platform 31, and the slide rail 314 extends in the direction in which the airtight water tank 10 and the transition cabin 20 are relatively arranged. The two ends of the slide rail 314 are respectively located in the transition cabin 20 and the airtight water tank 10, and the transport vehicle 32 slides with the slide rail 314. The slide rail 314 on the receiving platform 31 slides with the transport vehicle 32 to fix the moving path of the transport vehicle 32, so that the movement of the transport vehicle 32 is more controllable, which is convenient for setting the automatic drive control equipment and improving the transportation efficiency.

[0055] A driving structure is provided on the slide rail 314 serving as a bridge rail, for driving the transport vehicle 32 to move on the slide rail 314 .

[0056] Specifically, Figure 2As shown, in one embodiment, a first liquid level sensor 22 is provided in the transition chamber 20, and the first liquid level sensor 22 is used to detect the water level of the transition chamber 20. A second liquid level sensor 15 is provided in the airtight water pool 10, and the second liquid level sensor 15 is used to detect the water level of the airtight water pool 10. The first liquid level sensor 22 and the second liquid level sensor 15 are used to detect the water level of the transition chamber 20 and the water level of the airtight water pool 10, respectively, so as to monitor the water level of the transition chamber 20 and the water level of the airtight water pool 10 at all times, ensure that the water level is at a safe height, and judge the ambient air pressure in the airtight water pool 10 by the water level difference between the water level of the transition chamber 20 and the water level of the airtight water pool 10.

[0057] Furthermore, in one embodiment, a vacuum sensor 17 may be provided in the low pressure environment 12 of the airtight water pool 10 to test the vacuum degree of the airtight water pool 10, thereby ensuring the vacuum requirement of the test and improving the accuracy of the test.
