Detailed Implementation

[0014] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0015] In response to the continuous development and widespread application of UUV technology, this patent aims to propose a UUV testing system experimental platform, which will provide important support for the research, design and optimization of UUV technology, provide strong support for its further development and military application, and promote UUV technology to play a more important role in future naval warfare.

[0016] Reference Figures 1-5 As shown, the present invention provides a UUV testing system test platform. According to different functions, the test platform is divided into a platform body and an internal wireless power transmission system and a push / pull force testing mechanism. The platform body is welded from several rectangular combined water tank frames 11. The combined water tank frame 11 is an external frame structure with each panel embedded in the design. The bottom of the water tank is welded to an integrated steel plate and a reinforcing frame, resulting in a structurally sound structure with good strength. The top and front panels 115 of the combined water tank frame 11 are translucent, while the remaining non-observation surfaces 116 are fitted with non-transparent metal plates, preferably made of rigid material. Used as an experimental platform for unmanned aerial vehicles (UAVs), facilitating the hoisting of UAVs, black original sealing strips are installed between each panel and the combined water tank frame 11; the top of the combined water tank frame 11 is provided with an overflow port 117 and a water inlet 118, and the bottom is provided with a water outlet 119. The sides of the combined water tank frame 11 are also provided with a cable interface 120 and a signal cable interface 121. The water tank interfaces of the combined water tank frame 11 include the overflow port 117 and the water inlet 118 at the top and the water outlet 119 at the bottom, as well as correspondingly designed water inlet pipes, overflow pipes, drain pipes, vent pipes, level gauges, manholes and other accessories.

[0017] The top and front panels 115 of the combined water tank frame 11 of this invention are light-transmitting, which can effectively observe the movement position of the wireless power transmission coil, thereby increasing the radiation area of ​​the wireless power transmission receiving and transmitting coils. The deformation of the strain block can be measured through the push / pull force testing mechanism, thereby calculating the tensile force value and verifying the efficiency of the UUV 44 rim propeller under different working conditions. This provides a basis for the verification and optimization of product design parameters and provides important support and convenience for UUV 44 technology research and design.

[0018] The overall dimensions of the modular water tank frame 11 of this invention are 5m long, 1.5m wide, and 1.5m high. The top and front 115 of the water tank are made of transparent material, while the remaining non-observation surfaces 116 are made of steel plates. The bottom of the water tank is made of high-quality thick steel plate for fixing the push / pull force testing mechanism. The water tank is placed on the test site via a channel steel base 114. The water outlet 119 of the water tank is located at the bottom. The overflow outlet 117, the water inlet 118, and the cable interface 120 and signal cable interface 121 of the UUV 44 are respectively arranged on the upper sides of both ends of the water tank for water filling and drainage, as well as power supply and signal transmission of the UUV.

[0019] To increase the visibility of the tank, in a preferred embodiment, the front panel 115 (observation surface) is made of a transparent material, the non-observation surface 116 is made of a metal material, and the top is made of a lightweight transparent material.

[0020] For ease of installation, in a preferred embodiment, the water tank is rectangular in shape, suitable as an experimental platform for unmanned aerial vehicles (UAVs), and can also house a push-pull force testing system, facilitating the hoisting of the UAVs.

[0021] To improve the strength of the tank, in a preferred embodiment, the water tank adopts an external frame structure with each panel embedded in the design. Transparent materials are used in the light-transmitting parts, while other parts are made of rigid materials. The bottom of the water tank is welded to the reinforcing frame with an integrated steel plate, and the overall structure has good strength.

[0022] To address the issue of tank sealing, in a preferred embodiment, the water tank is sealed using a combined water tank frame 11 welded together, with black virgin sealing strips used between the water tank panels and the frame.

[0023] To facilitate interface standardization, in a preferred embodiment, the water tank interface is designed with accessories such as an inlet pipe, an overflow pipe, a drain pipe, a vent pipe, a level gauge, and a manhole. Since the internal UUV 44 requires external power supply and signal transmission, a cable connection port also needs to be designed. The water pipe interface and cable interface of the water tank are respectively located on both sides of the head and tail of the water tank, and are separate from each other.

[0024] To facilitate water filling of the water tank, in a preferred embodiment, the water inlet pipe of the water inlet 118 is connected from the side wall. When the water tank is filled using the pipeline pressure, a hydraulic water level control valve or float valve should be installed at the water outlet of the inlet pipe, with the control valve connected to the water tank from the top. When the pipe diameter is ≥5mm, the number of such valves is generally no less than two, and a maintenance valve should be installed before each control valve.

[0025] To facilitate drainage of the water tank, in a preferred embodiment, the drain outlet 119 is a water outlet pipe extending from the bottom of the side wall. The water outlet pipe is 50mm above the bottom of the water tank. An internally threaded (small diameter) or flanged (large diameter) gate valve is installed on the water outlet pipe; high-resistance shut-off valves are not permitted. To facilitate overflow of the water tank, the overflow port 117 is located on the side wall to ensure the water level does not become too high.

[0026] To facilitate cable sealing, in a preferred embodiment, the cable interface is used to secure the head side wall of the water tank. The cable interface 120 and signal cable interface 121 of the UUV 44 are connected using cable interfaces with an IP68 protection rating.

[0027] To facilitate understanding of the wireless charging moving mechanism, in a preferred embodiment, the wireless charging moving mechanism enables the wireless power transfer coil to move horizontally and vertically.

[0028] The wireless power transfer system includes a wireless power transfer system moving mechanism 22 and a wireless power transfer coil disposed on the wireless power transfer system moving mechanism 22. The wireless power transfer system moving mechanism 22 realizes the horizontal and vertical movement of the wireless power transfer coil through wireless charging. The wireless power transfer system moving mechanism 22 includes a base 221 and a base slide rail 226. The base 221 is connected to a base vertical movement control rod 224 through a coil base 225. The base vertical movement control rod 224 is respectively provided with a base horizontal movement control screw 222 and a horizontal movement slider 223.

[0029] To achieve multi-dimensional movement of the coil base, in a preferred embodiment, the wireless power transmission coil has a threaded hole and is connected to the vertical movement control rod 224 of the base via a screw pair. By rotating the vertical movement control rod 224, the wireless power transmission coil can achieve vertical displacement on the guide rod of the base. The guide rod of the wireless power transmission base 225 is used to limit the coil, so that the horizontal displacement of the coil is consistent with that of the coil base 225. The coil base 225 is fixed on the slider of the base slide rail 226. By rotating the horizontal movement control screw 223, the horizontal movement slider 222 is horizontally displaced, causing the coil base 225 and the coil to slide on the horizontal slide rail 222.

[0030] The push / pull force testing mechanism includes a UUV mounting base 332 and a support rail 333 mounted on the UUV mounting base 332. A limit stop 334 is provided at the front end of the support rail 333. The limit stop 334 is composed of a sensor bracket 335, a strain block 336 and a motion platform 337. A push / pull force sensor is mounted on the sensor bracket 335. A fixing ring 331 for mounting a UUV 44 is provided on the UUV mounting base 332.

[0031] In order to realize the push-pull force testing system, in a preferred embodiment, the UUV 44 is fixed to the UUV mounting base 332. When the UUV 44 is started, the power is transmitted to the UUV mounting base 332 through the UUV 44, and the push force is converted into an electrical signal and transmitted through the push / pull force testing mechanism.

[0032] To perform push / pull force testing, in a preferred embodiment, the UUV 44 is fixed to the UUV mounting base 332 by a fixing ring 331. The UUV mounting base 332 is partially fixed to the slider of the support rail 333. When the UUV 44 moves forward, the power of the UUV 44 is transmitted to the UUV mounting base 332, causing the UUV mounting base 332 to displace on the support rail 333, compressing the strain gauge 336 of the push / pull force testing mechanism and causing deformation. The amount of deformation is converted into an electrical signal output by the push / pull force sensor. Figure 5 As shown.

[0033] In order to achieve the push-pull force test, in a preferred embodiment, in order to prevent excessive deformation and protect the entire system, a limit stop 334 is designed at the maximum range to prevent the buoyancy effect from interfering with the experiment. A fixing ring 331 is used to fasten and fix the UUV 44 from the top, so that the UUV 44 and the base maintain consistency in movement.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
