Description

Technical Field

[0001] This invention relates to the field of liquid hydrogen experimental testing technology, and in particular to a mobile liquid hydrogen storage tank experimental platform system. Background Technology

[0002] Liquid hydrogen, as a high-energy-density clean energy source, has broad application prospects in transportation and energy sectors. During transportation by road and rail, liquid hydrogen storage tanks are subject to random vibrations, impacts, vehicle acceleration and deceleration, and turning, which can easily induce complex thermodynamic phenomena such as liquid sloshing, gas-liquid two-phase flow phase transitions, and pressure fluctuations within the tank, thus adversely affecting the structural integrity and thermal insulation performance of the storage tank.

[0003] Currently, the two-phase dynamic characteristics tests of liquid hydrogen storage tanks are mostly conducted in fixed laboratory environments. Existing experimental platforms have the following shortcomings: Infrastructure construction has a long cycle and requires large investments, making it difficult to quickly relocate experimental sites to meet experimental needs. The equipment is scattered, and after it is moved, the instruments, pipelines and control links need to be rebuilt, the on-site deployment cycle is long, and it cannot adapt to the needs of multi-site verification. The simulated operating conditions differ significantly from the real continuous, multi-degree-of-freedom coupled transportation environment, resulting in insufficient authenticity and reliability of the experimental data.

[0004] Therefore, there is an urgent need for an experimental platform that can be quickly deployed, flexibly moved, and capable of conducting multiphysics field tests on liquid hydrogen storage tanks in real and simulated transportation environments. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a mobile liquid hydrogen storage tank experimental platform system. By integrating a skid-mounted container-type liquid hydrogen storage tank, motion simulation device, testing sensor system, and safety protection system, the system enables the testing of the safety performance and thermodynamic behavior of the liquid hydrogen storage tank under real storage and transportation environments and controllable multi-degree-of-freedom motion conditions. This provides reliable experimental support for the structural optimization, safety assessment, and standardization of liquid hydrogen storage and transportation equipment.

[0006] The technical solution of the present invention is a mobile liquid hydrogen storage tank experimental platform system, including a skid-mounted container for carrying the experimental platform. The interior of the skid-mounted container is divided by a partition wall into an equipment area for integrated liquid hydrogen storage and experimental equipment and an operation control area for integrated control, monitoring and safety protection facilities. Skid-mounted containers can be selectively fixed to transport vehicles to subject liquid hydrogen storage tanks to real transport conditions; or fixed to test sites to apply controlled simulated transport conditions to the liquid hydrogen storage tanks via a six-degree-of-freedom motion platform.

[0007] Preferably, the explosion-proof isolation wall is equipped with an explosion-proof observation window, an airtight explosion-proof door at the bottom, and an explosion-proof sealing sleeve at the bottom; the airtight explosion-proof door is used to achieve safe passage and sealed isolation between the equipment area and the operation and control area; the explosion-proof sealing sleeve is used for pipelines to pass through the wall and maintain the airtightness between the areas.

[0008] Preferably, the containers corresponding to the equipment area have openable top covers and full-width double-leaf outward-opening doors on the end faces; The equipment area integrates a ground scale, a six-degree-of-freedom motion platform installed on the ground scale, a horizontal liquid hydrogen storage tank fixed on the six-degree-of-freedom motion platform, a valve and pipeline system, nitrogen cylinders, high-pressure helium cylinders, an atmospheric barometer, and a gas flow meter.

[0009] Preferably, the horizontal liquid hydrogen storage tank is equipped with temperature sensors, pressure sensors, and safety valves to monitor the thermodynamic state inside the tank in real time; an atmospheric pressure gauge is embedded in the container wall of the equipment area to monitor the atmospheric pressure of the experimental environment.

[0010] Preferably, the valve and piping system includes a filling valve, an exhaust valve, a nitrogen purging valve, and their corresponding vacuum-insulated pipes integrated into the inlet of the horizontal liquid hydrogen storage tank. The vacuum-insulated pipes are laid longitudinally along the top / side wall of the container's inner wall. The nitrogen purging valve is connected in sequence to a pressure reducing valve, a check valve, and a cryogenic control valve through a vacuum insulated pipeline to a nitrogen cylinder to achieve inert gas replacement and purging of the storage tank system. The downstream pipeline of the exhaust valve is connected in sequence to a heating device, a gas flow meter, and a flame arrester to reheat the discharged low-temperature hydrogen, measure its flow rate, and prevent backfire.

[0011] Preferably, the temperature sensor, pressure sensor, and safety valve are sealed and installed at the center of the top of the horizontal liquid hydrogen storage tank. The temperature sensors are arranged in a multi-point distributed manner. The measurement points include: measurement points evenly distributed around the outer wall of the inner liner of the horizontal liquid hydrogen storage tank, measurement points embedded inside the insulation layer, measurement points at the stress points of the supporting structure, and measurement points arranged along the height direction on the vertical probe inside the tank, so as to comprehensively obtain the temperature field distribution and thermal state of the storage tank under different operating conditions.

[0012] Preferably, the operation control area is used to integrate control and monitoring devices and safety protection equipment, specifically including a control and monitoring area, environmental safety devices, and a protective equipment area.

[0013] Preferably, the control and monitoring area includes a program control system, a data acquisition unit, a PLC industrial control station, a system mobile power supply, and an emergency shut-off button; The data acquisition unit is connected to a six-degree-of-freedom motion platform, a temperature sensor, a pressure sensor, a barometer, and a gas flow meter to achieve synchronous acquisition of multi-physics parameters. The PLC industrial control station connects to and controls the movement of the six-degree-of-freedom motion platform and the opening and closing of each electric valve.

[0014] Preferably, the environmental safety device includes a hydrogen concentration detector and an interlocked exhaust system; when the hydrogen concentration is detected to reach a preset threshold, an alarm is triggered and the exhaust system is activated to prevent the accumulation of combustible gas.

[0015] Preferably, the protective equipment area is equipped with protective equipment cabinets, which integrate and store anti-static and low-temperature resistant protective equipment and first aid toolboxes to provide emergency protection.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: 1. In existing technologies, traditional fixed laboratories require the installation of multiple hydrogen concentration detectors and exhaust fans at different heights in high-risk areas to monitor diffused gases. In contrast, the equipment area container of this invention adopts an openable top cover and a full-width double-leaf outward-opening door. During experiments, the cover and door can be opened to connect with the external environment, facilitating the rapid release of hydrogen vapors. At the same time, a flame arrester is connected in series with the exhaust pipe to prevent external ignition sources from causing backfire inside the container.

[0017] 2. Traditional experimental platforms involve dispersed equipment, requiring reconfiguration of instruments, pipelines, and control links after relocation, resulting in lengthy on-site deployment cycles and unsuitability for multi-site verification needs. This invention integrates liquid hydrogen storage tanks, motion simulation devices, testing and sensing systems, and safety protection systems into a single skid-mounted container. All connections are pre-installed and secured at the factory, eliminating the need for disassembly and reassembly on-site. The container is ready for use immediately after hoisting. The piping system is integrated within the container, reducing unnecessary external connections. After preparation, only connection to the local hydrogen supply system is required to begin remote operation experiments. This enables integrated hoisting, rapid deployment, and mobile transportation, significantly reducing on-site setup time and costs.

[0018] 3. Fixed laboratories can only simulate the working conditions of liquid hydrogen cylinders using vibration platforms, which differs significantly from the real, continuous, multi-degree-of-freedom coupled transportation environment, resulting in insufficient authenticity and reliability of experimental data. This invention employs two experimental methods: a real-world transportation test mode and a fixed-site simulation mode. It allows for the recording of dynamic behavior during actual transportation by hoisting the container onto the transport vehicle, obtaining experimental data under real transportation conditions. Alternatively, it enables the repeated simulation of different transportation stimuli in a fixed location under controllable conditions using a six-degree-of-freedom motion platform. The combination of these two modes is suitable for performance verification of liquid hydrogen storage tanks in various test scenarios, improving the authenticity and repeatability of experimental data.

[0019] 4. The temperature sensor adopts a multi-point distributed arrangement of "circumferential direction of the inner tank outer wall + vertical probe height direction inside the tank", forming a multi-source sensor network with the pressure sensor, gas flow meter, and ground scale; the data acquisition unit is connected to each sensor and motion platform in real time, and under continuous, multi-degree-of-freedom motion excitation conditions, it synchronously collects multiple physical field parameters such as temperature, pressure, flow rate, and tank mass change, so as to realize comprehensive testing of the thermo-dynamic response characteristics of liquid hydrogen storage tank.

[0022] To further understand the technical solution of this application, a specific example is used below for detailed explanation, such as... Figure 1-3 As shown, this embodiment provides a mobile liquid hydrogen storage tank experimental platform system, including a skid-mounted container 1. The skid-mounted container 1 serves as the load-bearing unit of the entire platform, integrating the liquid hydrogen storage tank, motion simulation device, testing and sensing system, piping system, and safety protection system. Through its skid-mounted structural design, the platform can be hoisted and fixed onto a transport vehicle for vehicle-mounted mobility; or it can be deployed as a whole at the test site, allowing for rapid deployment without disassembling the equipment, thereby reducing reliance on fixed experimental infrastructure.

[0023] like Figure 1 As shown, the interior of the skid-mounted container 1 is longitudinally divided into an equipment area 3 and an operation and control area 4 by an explosion-proof partition wall 2. Equipment area 3 is a high-risk experimental area used to house liquid hydrogen storage tanks and related experimental equipment; operation and control area 4 is a personnel operation and monitoring area used to house control systems, safety interlock devices, and protective equipment. This partitioned arrangement physically isolates the high-risk equipment from the personnel operation area, improving the overall safety of the experimental process.

[0024] like Figure 1 As shown, equipment area 3 integrates a ground scale 31, a six-degree-of-freedom motion platform 32, and a horizontal liquid hydrogen storage tank 33. The ground scale 31 is fixed to the bottom structure of the skid-mounted container 1 and is used to monitor the horizontal liquid hydrogen storage tank 33 and the changes in the liquid hydrogen mass inside in real time. The six-degree-of-freedom motion platform 32 is installed on the ground scale 31 and is used to apply continuous, multi-degree-of-freedom motion excitation to the horizontal liquid hydrogen storage tank 33. The horizontal liquid hydrogen storage tank 33 is fixed to the six-degree-of-freedom motion platform 32 by a support structure, and its axis is consistent with the longitudinal direction of the container to simulate the actual force and motion state of the liquid hydrogen storage tank during transportation. Equipment area 3 also includes a valve pipeline system 34, a nitrogen cylinder 35, a high-pressure helium cylinder 36, an atmospheric pressure gauge 37, and a gas flow meter 38, which are used to complete functions such as liquid hydrogen filling, discharge, replacement, and environmental parameter monitoring.

[0025] like Figure 1 As shown, the valve and piping system 34 is integrated with the inlet of the horizontal liquid hydrogen storage tank 33, including a filling valve 341, an exhaust valve 342, a nitrogen purging valve 343, and corresponding vacuum-insulated piping. The vacuum-insulated piping is laid along the top or side wall of the inner wall of the skid-mounted container 1 and is limited by fixed supports to reduce the impact of vibration under transportation and motion excitation conditions. Among them, the nitrogen purging valve 343 is connected to the pressure reducing valve 351, the one-way valve 352, and the cryogenic control valve 353 in sequence through the vacuum-insulated piping and then connected to the nitrogen cylinder 35 for purging the inside of the liquid hydrogen storage tank with inert gas; the downstream piping of the exhaust valve 342 is connected to the heating device 381, the gas flow meter 38, and the flame arrester 382 in sequence for temperature regulation, flow monitoring, and backfire protection of the exhaust gas. All pipelines are sealed with explosion-proof sealing sleeves 23 at the locations where they pass through the explosion-proof isolation wall 2 to prevent gas leakage and maintain the integrity of the area isolation. The valve pipeline system and gas treatment are connected to the outside world through full-width double-leaf outward-opening doors 39.

[0026] like Figure 1 , Figure 2As shown, the operation control area 4 is further divided into a control monitoring area 41, an environmental safety device area 42, and a protective equipment area 43. An explosion-proof observation window 21 is installed on the explosion-proof isolation wall 2 for personnel to observe the status of the equipment area 3 from within the operation control area 4; an airtight explosion-proof door 22 is installed at the bottom of the isolation wall to achieve equipment maintenance access and sealed isolation. The control monitoring area 41 houses a program control system 411, a data acquisition unit 412, a PLC industrial control station 413, a system mobile power supply 414, and an emergency cut-off button 415. The data acquisition unit 412 is connected to a six-degree-of-freedom motion platform 32, a temperature sensor 331, a pressure sensor 332, an atmospheric barometer 37, and a gas flow meter 38 for synchronous acquisition of multi-source parameters. The PLC industrial control station 413 is used for centralized control of the motion status of the six-degree-of-freedom motion platform 32 and the opening and closing of each electric valve.

[0027] The environmental safety device 42 includes a hydrogen concentration detector 421 and an interlocked exhaust system 422. The hydrogen concentration detectors 421 are positioned at different heights within equipment area 3 to monitor hydrogen leakage in real time. When the detected hydrogen concentration reaches a preset threshold, the system automatically triggers an audible and visual alarm and interlocks to activate the exhaust system 422, simultaneously performing a safety shutdown operation on non-essential equipment to reduce the risk of hydrogen accumulation. The protective equipment area 43 contains protective equipment cabinets, which centrally store anti-static and low-temperature resistant protective equipment 431 and a first-aid toolbox 432 to meet experimental operation and emergency response needs.

[0028] A temperature sensor 331, a pressure sensor 332, and a safety valve 333 are sealed and installed at the center of the top of the horizontal liquid hydrogen storage tank 33. The temperature sensor 331 is arranged in a multi-point distributed configuration, such as... Figure 3 As shown, the measurement points are set on the outer wall of the inner liner of the storage tank, inside the insulation layer, at key locations of the support structure, and at the position of the vertical probe inside the tank along the height direction, in order to obtain the temperature characteristics of the liquid hydrogen storage tank under different operating conditions. In experimental applications, the skid-mounted container 1 can be fixed as a whole to the transport vehicle, allowing the horizontal liquid hydrogen storage tank 33 to move synchronously with the vehicle to obtain real-world transport data; or the skid-mounted container 1 can be fixed to the test site, and a controllable multi-degree-of-freedom motion excitation can be applied through a six-degree-of-freedom motion platform 32 to simulate different transport conditions. In both modes, the data acquisition unit 412 synchronously collects temperature, pressure, and flow parameters related to the gas-liquid two-phase flow inside the liquid hydrogen storage tank, enabling data analysis for both real-world testing and repeatable simulation testing.

[0029] In this embodiment, due to the limited internal space of the container, it is necessary to accommodate various equipment such as storage tanks, motion platforms, pipelines, and gas cylinders. The present invention achieves an equivalent safety layout in an extremely compact space through longitudinal partitioning of explosion-proof walls, stacked equipment layout, embedded monitoring, and interlocked ventilation. The horizontal liquid hydrogen storage tank is aligned with the longitudinal direction of the container to reduce the lateral space occupied. The vacuum insulated pipeline is laid along the top or side wall of the container's inner wall to reduce the central space occupied.

[0030] In addition, containers must meet the height standards stipulated by national laws and regulations when on the road, and the height of vehicles carrying containers must not exceed 4.2 meters. This invention limits the size of skid-mounted containers according to the height standards stipulated by national laws and regulations, calculates the maximum envelope space of the experimental platform based on the limited dimensions, and designs the product to meet the requirements of national standards.

[0031] Vibration during transportation may cause loosening of pipeline connections, leakage, and relative displacement of instruments. This invention uses vacuum-insulated pipelines and fixed supports to limit the movement, reducing the impact of vibration under transportation and motion excitation conditions. Explosion-proof sealing sleeves are used where the pipelines pass through the isolation wall to enhance sealing and structural stability. The tank axis is aligned with the longitudinal direction of the container to simulate the stress state during actual transportation. The support structure is adapted to the multi-degree-of-freedom motion characteristics of the motion platform to ensure that the tank does not shift relative to the motion platform during the test.

[0032] Finally, compared to other media, liquid hydrogen has a low density, is flammable and explosive, and poses a high risk in experiments. Multiple safety devices need to be integrated within the limited space of the container. This invention employs a zoned design, physically isolating high-risk equipment from personnel operating areas. It utilizes a centralized control system with multiple safety mechanisms, including hydrogen concentration detectors, interlocked ventilation, flame arresters, and emergency shut-off, effectively reducing the risks of leakage, accumulation, and backfire during liquid hydrogen experiments and improving system operational safety. The protective equipment area is equipped with anti-static and cryogenic equipment and first-aid tools for easy emergency use.

[0033] This embodiment integrates a skid-mounted containerized liquid hydrogen storage tank, a motion simulation device, a testing sensor system, and a safety protection system to test the safety performance and thermodynamic behavior of the liquid hydrogen storage tank under real storage and transportation environments and controllable multi-degree-of-freedom motion conditions. This provides reliable experimental support for the structural optimization, safety assessment, and standardization of liquid hydrogen storage and transportation equipment.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
