Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydrogen storage container equipment, in particular to a hydrogen storage bottle group intelligent support system and a use method thereof. BACKGROUND

[0002] As the core infrastructure in the hydrogen energy industry chain, hydrogen refueling stations play a key role in the "production, storage, transportation and use" of hydrogen energy. Type IV hydrogen storage cylinders with high pressure and large capacity have become the preferred solution for fixed hydrogen storage cylinder groups due to their lightweight structure, high hydrogen storage density and long fatigue life, and are widely used in large-scale hydrogen storage scenarios in hydrogen refueling stations.

[0003] However, the current fixed high-pressure large-capacity type IV hydrogen storage cylinder group still faces many technical challenges in engineering practice. The existing support systems are mainly divided into two types: pure rigid support and pure flexible support. Pure rigid support completely fixes the two ends of the hydrogen storage cylinder to the cylinder group frame, although the structure is stable, but during the hydrogen charging and discharging process, due to the axial deformation (expansion or contraction) of the hydrogen storage cylinder, alternating restraint stress is easily generated at the junction of the plastic liner-carbon fiber layer-BOSS structure, which leads to a decrease in fatigue life and an increase in leakage risk. Pure flexible support allows one end of the hydrogen storage cylinder to slide freely, although it can alleviate the restraint stress, but due to the lack of effective constraints, it is easy to cause excessive deformation of the hydrogen storage cylinder, which will also cause stress concentration at the key connection, increasing the risk of structural failure.

[0004] In addition, the existing technology lacks real-time monitoring means for the stress and deformation state of the hydrogen storage cylinder, and cannot quantitatively evaluate and control the safety state of the support system. At the same time, the existing support system is a passive structure, which cannot dynamically adjust the restraint force and deformation according to the actual working condition of the hydrogen storage cylinder, and it is difficult to ensure the long-term safe operation of the hydrogen storage cylinder under complex hydrogen charging and discharging conditions.

[0005] Therefore, it is urgent to develop a support system that can monitor the support state of the hydrogen storage cylinder in real time and intelligently adjust the restraint force according to the monitoring data, in order to improve the safety, reliability and service life of the fixed hydrogen storage cylinder group. SUMMARY

[0076] Please refer to Figures 1-10 A hydrogen storage bottle group intelligent support system, comprising a flexible support device 1, a real-time monitoring system 2, an intelligent control system 3 and a bottle group frame 5.

[0077] Specifically as Figures 1-3 The bottle group frame 5 is internally provided with a large-capacity type IV hydrogen storage bottle 4, one end of which is fixedly installed on the bottle group frame 5, and the other end is flexibly connected to the bottle group frame 5 through the flexible support device 1;

[0078] The flexible support device 1 is fixedly installed on the bottle group frame 5 by bolts, 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 while limiting the circumferential rotation of the large-capacity type IV hydrogen storage bottle 4, and can reduce the restraint stress generated by the axial deformation of the large-capacity type IV hydrogen storage bottle 4;

[0079] The real-time monitoring system 2 is used for collecting the support state data of the large-capacity Type IV hydrogen storage bottle 4 in real time, including the restraining force of the flexible support device 1 on the large-capacity Type IV hydrogen storage bottle and the axial deformation amount of the large-capacity Type IV hydrogen storage bottle 4.

[0080] The intelligent control system 3 is used for controlling the restraining force and the deformation amount of the large-capacity Type IV hydrogen storage bottle 4 according to the data collected by the real-time monitoring system 2.

[0081] Specifically, as shown in 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.

[0082] The support flange 101 is fixedly installed on the bottle group frame 5 by bolts, and is used for flexibly connecting the anti-rotation extension sleeve 104 and the bottle group frame 5. The cylindrical sliding bushing 102 is installed on the circular inner wall surface of the support flange 101 by interference fit, and is fixed at the end face by a rotation-stopping screw. The cylindrical sliding bushing 102 is used for reducing the sliding resistance of the circular outer wall surface of the anti-rotation extension sleeve 104 on the circular inner wall surface 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 fixedly connected with the BOSS structure 401 of the large-capacity Type IV hydrogen storage bottle 4 by threads. The threaded connection makes the bottle bottom position of the large-capacity Type IV hydrogen storage bottle 4 convenient to install and disassemble, and realizes 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 in the support flange 101. The octagonal sliding bushing 103 is used for reducing 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.

[0083] Further, in the embodiment, specifically as shown in Figures 4-8 , the support flange 101 includes a support flange rectangular protruding structure 1011, a support flange through hole 1012, a support flange octagonal anti-rotation structure 1013 and a support flange rectangular recess 1014.

[0084] The support flange 101 is integrally connected with a support flange rectangular protruding structure 1011, which is used to accommodate the anti-rotation extension sleeve rectangular protruding structure 1041. The support flange rectangular protruding structure 1011 is provided with a support flange rectangular recess 1014 near the flange plate side of the support flange 101, which is used to accommodate the installation laser ranging sensor 201. The flange plate of the support flange 101 is provided with a support flange through hole 1012, which is used to guide the signal line 203 and the hydraulic pipeline 306 to the outside of the bottle group frame 5. The flange plate of the support flange 101 is integrally provided with a support flange octagonal anti-rotation structure 1013 on the opposite side, which corresponds to the anti-rotation extension sleeve octagonal anti-rotation structure 1043, and is used to prevent the circumferential rotation of the large-capacity type IV hydrogen storage bottle 4. At the same time, the support flange octagonal anti-rotation structure 1013 is axially designed with a sliding space to allow the anti-rotation extension sleeve 104 to axially displace within a certain range.

[0085] Further, in the embodiment, specifically as Figures 4-8 , the octagonal sliding bushing 103 includes an octagonal sliding bushing opening 1031 and an octagonal sliding bushing circular arc surface 1032.

[0086] The octagonal sliding bushing 103 is provided with an octagonal sliding bushing opening 1031 on one side, which is used to accommodate the anti-rotation extension sleeve rectangular protruding structure 1041. The octagonal sliding bushing 103 is integrally provided with an arc-shaped octagonal sliding bushing circular arc surface 1032 on the outside, which is used to prevent the anti-rotation extension sleeve octagonal anti-rotation structure 1043 from being stuck with the support flange octagonal anti-rotation structure 1013, and to reduce the frictional resistance between the support flange octagonal anti-rotation structure 1013 and the anti-rotation extension sleeve octagonal anti-rotation structure 1043.

[0087] Further, in the embodiment, specifically as Figures 4-8 , the anti-rotation extension sleeve 104 includes an anti-rotation extension sleeve rectangular protruding structure 1041, an anti-rotation extension sleeve connecting thread 1042, and an anti-rotation extension sleeve octagonal anti-rotation structure 1043.

[0088] The circular inner wall surface of the anti-rotation extension sleeve 104 is designed with anti-rotation extension sleeve connecting threads 1042 for fastening with the threads on the BOSS structure 401 of the large-capacity Type IV hydrogen storage bottle 4, fixing the anti-rotation extension sleeve 104 and the BOSS structure 401 of the large-capacity Type IV hydrogen storage bottle 4. The outer wall surface of the anti-rotation extension sleeve 104 is integrally connected with an anti-rotation extension sleeve octagonal anti-rotation structure 1043 corresponding to the support flange octagonal anti-rotation structure 1013, preventing the large-capacity Type IV hydrogen storage bottle 4 from rotating circumferentially. The anti-rotation extension sleeve octagonal anti-rotation structure 1043 is integrally connected with an anti-rotation extension sleeve rectangular protruding structure 1041 for adapting to the laser ranging sensor 201 and reflecting the laser emitted by the laser ranging sensor 201.

[0090] The laser ranging sensor 201 is installed in the support flange rectangular groove 1014 and is used to monitor the axial displacement of the large-capacity Type IV hydrogen storage bottle 4. One side of the force sensor 202 is fixed with the BOSS structure 401 of the large-capacity Type IV hydrogen storage bottle 4 through threads, and the other side is fixed with the hydraulic rod 308 in the intelligent control system 3 through threads, and the force sensor 202 is used to monitor the restraint force of the large-capacity Type IV hydrogen storage bottle 4.

[0091] The signal line 203 is electrically connected to the signal output interfaces of the laser ranging sensor 201 and the force sensor 202, then passes through the support flange through-hole 1012 to the outside of the bottle group frame 5, and after being arranged by the wire harness outside the bottle group frame 5, it is connected to the industrial computer 204. The signal line 203 is used to transmit the monitoring data signals of the laser ranging sensor 201 and the force sensor 202 to the industrial computer 204.

[0092] Specifically as Figure 4 , Figure 5 , Figure 9 and Figure 10 , the intelligent control system 3 includes a hydraulic control valve one 301, a hydraulic control valve two 302, a hydraulic control valve three 303, a constant pressure pump 304, an oil tank 305, a hydraulic pipeline 306, a hydraulic cylinder 307, and a hydraulic rod 308.

[0093] The hydraulic cylinder 307 is installed on the support flange 101 flange plate through bolts and is used to apply an axial force to the large-capacity Type IV hydrogen storage bottle 4, and the hydraulic rod 308 is fixed with the force sensor 202 through threads.

[0094] The hydraulic control valve one 301, the hydraulic control valve two 302, and the hydraulic control valve three 303 are installed on the hydraulic pipeline 306, and are used for controlling the oil passage and pressure. When the hydraulic control valve connects the oil inlet pipeline to the rodless cavity of the hydraulic cylinder 307, the hydraulic rod 308 extends outward, and exerts pressure on the BOSS structure 401 of the large-capacity type IV hydrogen storage bottle 4. When the hydraulic control valve connects the oil inlet pipeline to the rod cavity of the hydraulic cylinder 307, the hydraulic rod 308 retracts inward, and exerts tension on the BOSS structure 401 of the large-capacity type IV hydrogen storage bottle 4. Each hydraulic control valve is independently controlled by the industrial computer 204, and can independently control a single large-capacity type IV hydrogen storage bottle 4 that exceeds the safety range.

[0095] The hydraulic pipeline 306 is connected to the rod cavity and the rodless cavity of the hydraulic cylinder 307, respectively, and then passes through the support flange through hole 1012 to the outside of the bottle group frame 5, and is sequentially connected to the constant pressure pump 304 and the oil tank 305 through the annular pipeline and the hydraulic control valve.

[0096] 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 for pressurizing and delivering 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 for storing the working oil medium required by the hydraulic system.

[0097] Embodiment 2

[0098] Please refer to Figures 1-10 On the basis of the above-mentioned embodiments, the application further provides a use method of the hydrogen storage bottle group intelligent support system, which specifically includes the following steps:

[0099] Step 1: Start the real-time monitoring system 2, and preset the allowable deformation range and the allowable restraint force range of the large-capacity type IV hydrogen storage bottle 4 in the industrial computer 204.

[0100] Step 2: Collect the axial deformation data of the large-capacity type IV hydrogen storage bottle 4 in real time by using the laser ranging sensor 201, collect the restraint force data borne by the large-capacity type IV hydrogen storage bottle 4 in real time by using the force sensor 202, and transmit the sensor collected data to the industrial computer 204 through the signal line 203.

[0101] Step 3: Use the industrial computer 204 to judge whether the data collected by the laser ranging sensor 201 and the data collected by the force sensor 202 exceed the preset allowable deformation range and the allowable restraint force range of the large-capacity type IV hydrogen storage bottle 4 in real time, respectively.

[0102] Step 4: Start the intelligent control system 3, and the constant pressure pump 304 pumps the hydraulic oil from the oil tank 305 to the hydraulic control valve one 301, the hydraulic control valve two 302 and the hydraulic control valve three 303 through the hydraulic pipeline 306, and then the hydraulic oil is pumped into the hydraulic cylinder 307 to act on the hydraulic rod 308 through the adjustment of the hydraulic control valve.

[0103] Step 5: The industrial computer 204 independently controls the hydraulic control valve one 301, the hydraulic control valve two 302 and the hydraulic control valve three 303, so that the support state of the single large-capacity type IV hydrogen storage bottle 4 in the hydrogen storage bottle group can be independently adjusted.

[0104] Among them, for a single large-capacity type IV hydrogen storage bottle 4, the intelligent control system 3 has four working conditions, which specifically include the following steps:

[0105] When the collected data of the laser ranging sensor 201 and the force sensor 202 are both within their safe ranges: the industrial computer 204 does not control the hydraulic control valve, so that the intelligent control system 3 remains in the original working state.

[0106] When the collected data of the laser ranging sensor 201 and the force sensor 202 are both beyond their safe ranges: the industrial computer 204 throws an error (i.e. the safety threshold is unreasonable), and the intelligent control system 3 cannot work. In this case, the safety threshold needs to be manually adjusted to a reasonable range.

[0107] When the collected data of the laser ranging sensor 201 is beyond its safe range and the collected data of the force sensor 202 is within its safe range: if the hydrogen storage bottle expands and deforms, the industrial computer 204 connects the hydraulic cylinder 307 to the rodless cavity of the hydraulic control valve and adjusts the hydraulic control valve to an appropriate opening degree, so that the extension amount of the hydraulic rod 308 increases, so as to strengthen the restraining force on the hydrogen storage bottle, until the axial deformation amount of the hydrogen storage bottle decreases to within the safe range; if the hydrogen storage bottle shrinks and deforms, the industrial computer 204 connects the hydraulic cylinder 307 to the rod cavity of the hydraulic control valve and adjusts the hydraulic control valve to an appropriate opening degree, so that the extension amount of the hydraulic rod 308 decreases, so as to weaken the restraining force on the hydrogen storage bottle, until the axial deformation amount of the hydrogen storage bottle decreases to within the safe range.

[0108] When the collected data of the laser ranging sensor 201 is within its safe range and the collected data of the force sensor 202 is beyond its safe range: if the hydrogen storage bottle expands and deforms, the industrial computer 204 connects the hydraulic cylinder 307 to the rod cavity of the hydraulic control valve and adjusts the hydraulic control valve to an appropriate opening degree, so that the extension amount of the hydraulic rod 308 decreases, so as to weaken the restraining force on the hydrogen storage bottle, until the restraining force on the hydrogen storage bottle decreases to within the safe range; if the hydrogen storage bottle shrinks and deforms, the industrial computer 204 connects the hydraulic cylinder 307 to the rodless cavity of the hydraulic control valve and adjusts the hydraulic control valve to an appropriate opening degree, so that the extension amount of the hydraulic rod 308 increases, so as to weaken the restraining force on the hydrogen storage bottle, until the restraining force on the hydrogen storage bottle decreases to within the safe range.
