Description

Technical Field

[0001] This invention relates to the field of hydrogen storage container equipment technology, and in particular to an intelligent support system for hydrogen storage cylinder groups and its usage method. Background Technology

[0002] Hydrogen refueling stations, as core infrastructure in the hydrogen energy industry chain, play a crucial role in the "production, storage, transportation, and utilization" of hydrogen energy. High-pressure, high-capacity Type IV hydrogen storage cylinders, due to their advantages such as lightweight structure, high hydrogen storage density, and long fatigue life, have become the preferred solution for stationary hydrogen storage cylinder groups and are widely used in large-scale hydrogen storage scenarios at hydrogen refueling stations.

[0003] However, stationary high-pressure, large-capacity Type IV hydrogen storage cylinder assemblies still face numerous technical challenges in engineering practice. Existing support systems are mainly divided into two types: purely rigid supports and purely flexible supports. Purely rigid supports completely fix both ends of the hydrogen storage cylinder to the cylinder assembly frame. While structurally stable, during hydrogen filling and discharging, the axial deformation (expansion or contraction) of the storage cylinder easily generates alternating restraint stress at the interface of the plastic inner liner-carbon fiber layer-BOSS structure, leading to decreased fatigue life and increased leakage risk. Purely flexible supports allow one end of the storage cylinder to slide freely, which can alleviate restraint stress, but due to the lack of effective constraint, it easily leads to excessive deformation of the storage cylinder, also causing stress concentration at critical connections and increasing the risk of structural failure.

[0004] Furthermore, existing technologies lack real-time monitoring methods for the stress and deformation state of hydrogen storage cylinders, making it impossible to quantitatively assess and control the safety status of the support system. At the same time, existing support systems are mostly passive structures, unable to dynamically adjust constraint forces and deformation amounts according to the actual operating conditions of the hydrogen storage cylinders, thus making it difficult to ensure the long-term safe operation of hydrogen storage cylinders under complex hydrogen filling and discharging conditions.

[0005] Therefore, there is an urgent need to develop a support system that can monitor the support status of hydrogen storage cylinders in real time and intelligently adjust the constraint force based on the monitoring data, so as to improve the safety, reliability and service life of stationary hydrogen storage cylinder groups. Summary of the Invention

[0006] The main objective of this invention is to overcome the shortcomings of existing technologies and provide an intelligent support system for hydrogen storage cylinder groups and its usage method. This not only solves the structural and control deficiencies of existing support systems but also provides a complete technical solution for the intelligent and safe operation of stationary high-pressure hydrogen storage cylinder groups, possessing significant engineering application value and market prospects.

[0007] The technical solution adopted by the present invention to achieve its technical objective is: an intelligent support system for hydrogen storage cylinder groups, including a flexible support device, a real-time monitoring system, an intelligent control system, and a cylinder group frame; The cylinder assembly frame contains a large-capacity Type IV hydrogen storage cylinder. One end of the large-capacity Type IV hydrogen storage cylinder is fixedly installed on the cylinder assembly frame, and the other end is flexibly connected to the cylinder assembly frame through a flexible support device. The flexible support device is fixedly installed on the cylinder group frame by bolts. It is used to flexibly connect the large-capacity Type IV hydrogen storage cylinder to the cylinder group frame, accommodate the axial sliding of the large-capacity Type IV hydrogen storage cylinder, and restrict the circumferential rotation of the large-capacity Type IV hydrogen storage cylinder. It can reduce the restraint stress caused by the axial deformation of the large-capacity Type IV hydrogen storage cylinder. The real-time monitoring system is used to collect support status data of large-capacity Type IV hydrogen storage cylinders in real time, including the restraining force of the flexible support device on the large-capacity Type IV hydrogen storage cylinders and the axial deformation of the large-capacity Type IV hydrogen storage cylinders. The intelligent control system is used to control the constraint force and deformation of large-capacity Type IV hydrogen storage cylinders based on data collected by the real-time monitoring system.

[0008] Preferably, the flexible support device includes a support flange, a cylindrical sliding bushing, an octagonal sliding bushing, and an anti-rotation extension sleeve; The support flange is fixedly installed on the bottle assembly frame by bolts; The cylindrical sliding bushing is installed on the inner circular wall of the support flange by an interference fit and is fixed at the end face by an anti-rotation screw. One end of the anti-rotation extension sleeve is inserted into the inside of the cylindrical sliding bushing, and the other end is fixedly connected to the BOSS structure of the large-capacity type IV hydrogen storage cylinder by threads. The octagonal sliding bushing is installed on the anti-rotation extension sleeve by an interference fit and is located inside the support flange.

[0009] Preferably, the supporting flange includes a rectangular protruding structure, a through hole, an octagonal anti-rotation structure, and a rectangular groove. The rectangular protruding structure of the supporting flange is integrally connected to the supporting flange; The rectangular groove of the support flange is formed on the side of the rectangular protruding structure of the support flange near the flange plate. The through hole of the support flange is opened on the flange of the support flange; The octagonal anti-rotation structure of the supporting flange is integrally installed on the opposite side of the flange of the supporting flange.

[0010] Preferably, the octagonal sliding bushing includes an octagonal sliding bushing opening and an octagonal sliding bushing arc surface; The opening of the octagonal sliding bushing is located on one side of the octagonal sliding bushing; The octagonal sliding bushing has an integrally formed arc surface on the outer side of the octagonal sliding bushing.

[0011] Preferably, the anti-rotation extension sleeve includes a rectangular protruding structure, a connecting thread, and an octagonal anti-rotation structure. The anti-rotation extension sleeve connection thread is provided on the circular inner wall surface of the anti-rotation extension sleeve; The octagonal anti-rotation structure of the anti-rotation extension sleeve is integrally connected to the outer wall surface of the anti-rotation extension sleeve. The rectangular protruding structure of the anti-rotation extension sleeve is integrally connected to the octagonal anti-rotation structure of the anti-rotation extension sleeve.

[0012] Preferably, the real-time monitoring system includes a laser rangefinder, a force sensor, a signal line, and an industrial control computer; The laser rangefinder is mounted in the rectangular groove of the supporting flange; One side of the force sensor is fixed to the BOSS structure of the large-capacity Type IV hydrogen storage cylinder by threads, and the other side is fixed to the hydraulic rod in the intelligent control system by threads. The signal line is electrically connected to the signal output interfaces of the laser rangefinder and the force sensor, and leads to the industrial control computer.

[0013] Preferably, the intelligent control system includes hydraulic control valve one, hydraulic control valve two, hydraulic control valve three, constant pressure pump, oil tank, hydraulic pipeline, hydraulic cylinder and hydraulic rod; The hydraulic cylinder is bolted to the support flange. The hydraulic rod and the force sensor are fixed together by threads; The hydraulic control valve one, hydraulic control valve two, and hydraulic control valve three are installed on the hydraulic pipeline; The hydraulic lines are respectively connected to the rod chamber and the rodless chamber of the hydraulic cylinder; the constant pressure pump is fixedly installed above the oil tank, with its oil inlet connected to the oil tank and its oil outlet connected to the hydraulic lines. The oil tank is placed on the bottom plate of the bottle assembly frame.

[0014] Preferably, each of the hydraulic control valves is independently controlled by an industrial computer, enabling independent control of a single large-capacity Type IV hydrogen storage cylinder.

[0015] This invention also provides a method for using an intelligent support system for hydrogen storage cylinder groups, comprising the following steps: Step 1: Turn on the real-time monitoring system and preset the allowable deformation range and allowable restraint force range of the large-capacity Type IV hydrogen storage cylinder in the industrial control computer; Step 2: Use a laser rangefinder to collect axial deformation data of the large-capacity Type IV hydrogen storage cylinder in real time, use a force sensor to collect restraint force data of the large-capacity Type IV hydrogen storage cylinder in real time, and transmit the data to the industrial control computer through a signal line. Step 3: Use an industrial control computer to determine in real time whether the collected data exceeds the preset allowable deformation range and allowable restraint force range; Step 4: Activate the intelligent control system. The constant pressure pump pumps hydraulic oil from the oil tank through the hydraulic pipeline to the hydraulic control valve. After adjustment, it is pumped into the hydraulic cylinder to act on the hydraulic rod. Step 5: Use an industrial control computer to independently control the hydraulic control valve to independently adjust the support status of a single large-capacity Type IV hydrogen storage cylinder in the hydrogen storage cylinder group.

[0016] Preferably, the method further includes the following step: when the data collected by the laser rangefinder and the force sensor are both within their safe range, the industrial control computer controls the hydraulic control valve to remain inactive, so that the intelligent control system maintains its original working state.

[0017] Preferably, the method further includes the following step: when the data collected by both the laser rangefinder and the force sensor exceed their safe range, the industrial control computer throws an error and the intelligent control system cannot work. In this case, the safety threshold needs to be manually adjusted to a reasonable range.

[0018] Preferably, the method further includes the following step: when the data collected by the laser rangefinder exceeds its safe range while the data collected by the force sensor is within its safe range: If the hydrogen storage cylinder expands and deforms, the industrial control computer will connect the hydraulic control valve to the rodless chamber of the hydraulic cylinder and adjust the hydraulic control valve to a suitable opening, so as to increase the extension of the hydraulic rod and strengthen the constraint on the hydrogen storage cylinder until the axial deformation of the hydrogen storage cylinder is reduced to a safe range. If the hydrogen storage cylinder shrinks and deforms, the industrial control computer connects the hydraulic control valve to the rod chamber of the hydraulic cylinder and adjusts the hydraulic control valve to a suitable opening, so as to reduce the outward extension of the hydraulic rod and strengthen the constraint on the hydrogen storage cylinder until the axial deformation of the hydrogen storage cylinder is reduced to a safe range.

[0019] Preferably, the method further includes the following step: when the data collected by the laser rangefinder is within its safe range while the data collected by the force sensor exceeds its safe range: If the hydrogen storage cylinder expands and deforms, the industrial control computer connects the hydraulic control valve to the rod chamber of the hydraulic cylinder and adjusts the hydraulic control valve to a suitable opening, so as to reduce the extension of the hydraulic rod and weaken the restraint force on the hydrogen storage cylinder until the restraint force on the hydrogen storage cylinder is reduced to a safe range. If the hydrogen storage cylinder shrinks and deforms, the industrial control computer connects the hydraulic control valve to the rodless chamber of the hydraulic cylinder and adjusts the hydraulic control valve to a suitable opening, increasing the extension of the hydraulic rod to reduce the restraint force on the hydrogen storage cylinder until the restraint force on the hydrogen storage cylinder drops to a safe range.

[0020] Compared with the prior art, the beneficial effects of the present invention are: The intelligent support system for hydrogen storage cylinders and its usage method can effectively reduce stress concentration: through the synergistic effect of the flexible support device and the intelligent control system, it avoids excessive restraint stress caused by pure rigid support and prevents excessive deformation caused by pure flexible support, significantly reducing the peak stress at the junction of the plastic inner liner-carbon fiber layer-BOSS structure, and improving the structural safety and fatigue life of the hydrogen storage cylinder.

[0021] The intelligent support system for hydrogen storage cylinders and its usage method enable real-time monitoring and intelligent control: by using force sensors and laser rangefinders to collect data on the restraint force and axial deformation of the hydrogen storage cylinders in real time, and combining this with an industrial control computer for data processing and decision-making, the system enables real-time monitoring and intelligent control of the support status of the hydrogen storage cylinders, ensuring that they are always within a safe operating range.

[0022] The intelligent support system for the hydrogen storage cylinder group and its usage method enable independent control of the hydrogen storage cylinders with high reliability: the intelligent control system can independently adjust the support state of a single hydrogen storage cylinder, has multi-condition adaptive capability, and can dynamically adjust the direction and magnitude of the hydraulic force during hydrogen filling and discharging, significantly improving the operational reliability and safety of the entire hydrogen storage cylinder group.

[0023] The intelligent support system for hydrogen storage cylinders and its usage method are reasonably structured and easy to install: the flexible support device adopts a modular design, which is convenient for installation and disassembly, maintenance and replacement, and has good sealing performance and anti-rotation function, making it suitable for high-pressure and high-frequency variable load conditions.

[0040] Example 1: Please see Figures 1-10 A smart support system for hydrogen storage cylinder groups includes a flexible support device 1, a real-time monitoring system 2, an intelligent control system 3, and a cylinder group frame 5.

[0041] Specifically, such as Figures 1-3 The bottle frame 5 is equipped with a large-capacity Type IV hydrogen storage bottle 4. One end of the large-capacity Type IV hydrogen storage bottle 4 is fixedly installed on the bottle frame 5, and the other end is flexibly connected to the bottle frame 5 through a flexible support device 1. The flexible support device 1 is fixedly installed on the bottle group frame 5 by bolts. It is used to flexibly connect the large-capacity type IV hydrogen storage bottle 4 and the bottle group frame 5, accommodate the axial sliding of the large-capacity type IV hydrogen storage bottle 4, and restrict the circumferential rotation of the large-capacity type IV hydrogen storage bottle 4. It can reduce the restraint stress caused by the axial deformation of the large-capacity type IV hydrogen storage bottle 4. The real-time monitoring system 2 is used to collect the support status data of the large-capacity type IV hydrogen storage cylinder 4 in real time, including the restraining force of the flexible support device 1 on the large-capacity type IV hydrogen storage cylinder and the axial deformation of the large-capacity type IV hydrogen storage cylinder 4. The intelligent control system 3 is used to control the constraint force and deformation of the large-capacity type IV hydrogen storage cylinder 4 based on the data collected by the real-time monitoring system 2.

[0042] Specifically, such as Figures 4-5 The flexible support device 1 includes a support flange 101, a cylindrical sliding bushing 102, an octagonal sliding bushing 103, and an anti-rotation extension sleeve 104.

[0043] The support flange 101 is bolted to the cylinder assembly frame 5, serving as a flexible connection between the anti-rotation extension sleeve 104 and the cylinder assembly frame 5. A cylindrical sliding bushing 102 is installed on the inner circular wall of the support flange 101 via an interference fit and is secured at its end face with an anti-rotation screw. The cylindrical sliding bushing 102 reduces the sliding resistance of the outer circular wall of the anti-rotation extension sleeve 104 on the inner circular wall of the support flange 101. One end of the anti-rotation extension sleeve 104 is inserted into the cylindrical sliding bushing 102, and the other end is threadedly connected to the BOSS structure 401 of the large-capacity Type IV hydrogen storage cylinder 4. This threaded connection facilitates installation and removal of the bottom of the large-capacity Type IV hydrogen storage cylinder 4, while also ensuring the sealing of the internal medium. The octagonal sliding bushing 103 is installed on the anti-rotation extension sleeve 104 by interference fit and is located inside the support flange 101. The octagonal sliding bushing 103 is used to reduce the sliding resistance of the octagonal outer wall surface of the anti-rotation extension sleeve 104 on the octagonal inner wall surface of the support flange 101.

[0044] Furthermore, in this embodiment, specifically as follows: Figures 4-8 The support flange 101 includes a rectangular protruding structure 1011, a through hole 1012, an octagonal anti-rotation structure 1013, and a rectangular groove 1014.

[0045] A rectangular protruding structure 1011 is integrally connected to the support flange 101, which is used to accommodate the rectangular protruding structure 1041 of the anti-rotation extension sleeve. A rectangular groove 1014 is provided on the flange side of the support flange 101 near the flange plate, which is used to accommodate the installation of the laser rangefinder sensor 201. A through hole 1012 is provided on the flange plate of the support flange 101, which is used to guide the signal line 203 and the hydraulic pipeline 306 to the outside of the bottle assembly frame 5. An octagonal anti-rotation structure 1013 is integrally provided on the opposite side of the flange of the supporting flange 101. The octagonal anti-rotation structure 1013 and the octagonal anti-rotation extension sleeve 1043 are correspondingly matched to prevent the large-capacity type IV hydrogen storage cylinder 4 from rotating circumferentially. At the same time, the octagonal anti-rotation structure 1013 is designed with axial sliding space to allow the anti-rotation extension sleeve 104 to make axial displacement within a certain range.

[0046] Furthermore, in this embodiment, specifically as follows: Figures 4-8 The octagonal sliding bushing 103 includes an octagonal sliding bushing opening 1031 and an octagonal sliding bushing arc surface 1032.

[0047] The octagonal sliding bushing 103 has an octagonal sliding bushing opening 1031 on one side, which is used to accommodate the rectangular protruding structure 1041 of the anti-rotation extension sleeve. The outer side of the octagonal sliding bushing 103 is integrally provided with an arc-shaped octagonal sliding bushing arc surface 1032. The octagonal sliding bushing arc surface 1032 is used to prevent the octagonal anti-rotation structure 1043 of the anti-rotation extension sleeve from getting stuck with the octagonal anti-rotation structure 1013 of the support flange, and at the same time reduce the frictional resistance between the octagonal anti-rotation structure 1013 of the support flange and the octagonal anti-rotation structure 1043 of the anti-rotation extension sleeve.

[0048] Furthermore, in this embodiment, specifically as follows: Figures 4-8 The anti-rotation extension sleeve 104 includes a rectangular protruding structure 1041, a connecting thread 1042, and an octagonal anti-rotation structure 1043.

[0049] The inner circular wall of the anti-rotation extension sleeve 104 is designed with an anti-rotation extension sleeve connecting thread 1042. The anti-rotation extension sleeve connecting thread 1042 is used to fasten with the thread on the BOSS structure 401 of the large-capacity type IV hydrogen storage cylinder 4, thus fixing the anti-rotation extension sleeve 104 and the BOSS structure 401 of the large-capacity type IV hydrogen storage cylinder 4. An octagonal anti-rotation structure 1043 is integrally connected to the outer wall of the anti-rotation extension sleeve 1044. The octagonal anti-rotation structure 1043 corresponds to and cooperates with the octagonal anti-rotation structure 1013 of the support flange to prevent the large-capacity type IV hydrogen storage cylinder 4 from rotating circumferentially. An octagonal anti-rotation structure 1041 is integrally connected to the octagonal anti-rotation structure 1043. The rectangular protrusion 1041 is used to adapt to the laser rangefinder sensor 201 and reflect the laser emitted by the laser rangefinder sensor 201.

[0050] Specifically, such as Figure 4 , Figure 5 , Figure 9 and Figure 10 The real-time monitoring system 2 includes a laser rangefinder 201, a force sensor 202, a signal line 203, and an industrial control computer 204.

[0051] A laser rangefinder 201 is mounted in the rectangular groove 1014 of the support flange. The laser rangefinder 201 is used to monitor the axial displacement of the large-capacity type IV hydrogen storage cylinder 4. One side of the force sensor 202 is fixed to the BOSS structure 401 of the large-capacity type IV hydrogen storage cylinder 4 by threads, and the other side is fixed to the hydraulic rod 308 in the intelligent control system 3 by threads. The force sensor 202 is used to monitor the restraint force of the large-capacity type IV hydrogen storage cylinder 4.

[0052] Signal line 203 is electrically connected to the signal output interfaces of laser rangefinder 201 and force sensor 202, and then passes through the through hole 1012 of the support flange to the outside of the bottle frame 5. After being organized by the wire harness on the outside of the bottle frame 5, it leads to the industrial control computer 204. Signal line 203 is used to transmit the monitoring data signals of laser rangefinder 201 and force sensor 202 to industrial control computer 204.

[0053] Specifically, such as Figure 4 , Figure 5 , Figure 9 and Figure 10 The intelligent control system 3 includes hydraulic control valve 1 301, hydraulic control valve 2 302, hydraulic control valve 3 303, constant pressure pump 304, oil tank 305, hydraulic pipeline 306, hydraulic cylinder 307 and hydraulic rod 308.

[0054] The hydraulic cylinder 307 is bolted to the flange of the support flange 101 and is used to apply axial force to the large-capacity type IV hydrogen storage cylinder 4. The hydraulic rod 308 and the force sensor 202 are fixed by threads.

[0055] Hydraulic control valves 301, 302, and 303 are installed on hydraulic lines 306 to control the direction and pressure of hydraulic fluid. When the hydraulic control valves connect the inlet line to the rodless chamber of hydraulic cylinder 307, the hydraulic rod 308 extends outward, applying pressure to the BOSS structure 401 of the large-capacity type IV hydrogen storage cylinder 4. When the hydraulic control valves connect the inlet line to the rod chamber of hydraulic cylinder 307, the hydraulic rod 308 retracts inward, applying tension to the BOSS structure 401 of the large-capacity type IV hydrogen storage cylinder 4. Each hydraulic control valve is independently controlled by the industrial computer 204, allowing independent control of a single large-capacity type IV hydrogen storage cylinder 4 that exceeds the safety range.

[0056] Hydraulic lines 306 are connected to the rod chamber and rodless chamber of hydraulic cylinder 307 respectively, and then through the support flange through hole 1012 to the outside of the bottle group frame 5. After passing through the annular flexible pipeline and hydraulic control valve, they are connected to the constant pressure pump 304 and oil tank 305 in sequence. The constant pressure pump 304 is fixedly installed above the oil tank 305. The oil inlet of the constant pressure pump 304 is connected to the oil tank 305, and the oil outlet is connected to the hydraulic pipeline 306. The constant pressure pump 304 is used to pressurize and deliver the oil in the oil tank 305 to the hydraulic pipeline 306 and the hydraulic cylinder 307. The oil tank 305 is placed on the bottom plate of the bottle group frame 5 and is used to store the working oil medium required by the hydraulic system.

[0057] Example 2: Please see Figures 1-10 Based on the above embodiments, this invention also provides a method for using an intelligent support system for hydrogen storage cylinder groups, the method of which specifically includes the following steps: Step 1: Turn on the real-time monitoring system 2 and preset the allowable deformation range and allowable restraint force range of the large-capacity type IV hydrogen storage cylinder 4 in the industrial control computer 204; Step 2: Use laser rangefinder 201 to collect axial deformation data of large-capacity type IV hydrogen storage cylinder 4 in real time, and use force sensor 202 to collect restraint force data of large-capacity type IV hydrogen storage cylinder 4 in real time, and transmit the sensor data to industrial control computer 204 through signal line 203. Step 3: Use the industrial control computer 204 to determine in real time whether the data collected by the laser rangefinder 201 and the force sensor 202 exceed the preset allowable deformation range and allowable restraint force range of the large-capacity type IV hydrogen storage cylinder 4. Step 4: Turn on the intelligent control system 3. The constant pressure pump 304 pressurizes the hydraulic oil from the oil tank 305 through the hydraulic pipeline 306 and pumps it to the hydraulic control valve 1 301, hydraulic control valve 2 302, and hydraulic control valve 303 respectively. After adjusting the flow and pressure through the hydraulic control valves, it is then pumped into the hydraulic cylinder 307 to act on the hydraulic rod 308. Step 5: Use the industrial control computer 204 to independently control hydraulic control valve 1 301, hydraulic control valve 2 302, and hydraulic control valve 3 303, so that they can independently adjust the support status of a single large-capacity type IV hydrogen storage cylinder 4 in the hydrogen storage cylinder group.

[0058] For a single large-capacity Type IV hydrogen storage cylinder 4, the intelligent control system 3 operates under four conditions, specifically including the following steps: When the data collected by the laser rangefinder 201 and the force sensor 202 are both within their safe range, the industrial control computer 204 controls the hydraulic control valve to remain still, so that the intelligent control system 3 maintains its original working state.

[0059] When the data collected by both the laser rangefinder 201 and the force sensor 202 exceed their safe range, the industrial control computer 204 throws an error (i.e., the safety threshold is unreasonable), and the intelligent control system 3 cannot work.
