Technical Field

[0001] The invention relates to the technical field of pressure stabilization equipment, and in particular to a cluster hydrogen storage pressure stabilization device. Background Art

[0002] Cluster hydrogen storage is a method of storing hydrogen using cluster materials, where clusters are microscopic or submicroscopic aggregates composed of several to thousands of atoms, molecules or ions through physical or chemical bonding forces. This method of hydrogen storage has important application potential in the development of hydrogen energy technology. According to different studies, the performance of cluster hydrogen storage can be optimized by different methods:

[0003] For example, lithium-modified B 6 Cluster (LiB 6 ) showed good performance in hydrogen storage. 6 In the three possible structures of the cluster, hydrogen molecules can undergo dissociative adsorption, while lithium atoms can undergo dissociative adsorption in B 6 The cluster surface does not aggregate, and each lithium atom adsorbs several hydrogen molecules, especially the cage-shaped B modified by two lithium atoms. 6 The cluster can adsorb the largest number of hydrogen molecules, with a hydrogen storage mass fraction of 20.38% and an average adsorption energy of hydrogen molecules of 1.683 kcal / mol, showing the feasibility of using it as a hydrogen storage material under normal temperature and pressure conditions;

[0004] In addition, CN 4 and CN 4 2+ The clusters also show good hydrogen storage properties, with each CNa 4 2+ The cluster can effectively bind with up to 16 hydrogen molecules, achieving a mass hydrogen storage density of 23.5%. 4 2+ The average interaction energy of the clusters is between 2.107 and 4.948 Kcal / mol, and their mass hydrogen storage density is between 7.1 and 23.7 wt%, which meets the target required by the U.S. Department of Energy (5.5 wt%).

[0005] Li 3 O superalkaline clusters also show good hydrogen storage properties. Each Li atom can effectively adsorb up to three hydrogen molecules. 3 The average adsorption energy of the O cluster surface ranges from 1.959 to 3.591 kCal / mol, which meets the thermodynamic requirements of reversible hydrogen absorption and desorption reactions at near room temperature.

[0006] Cage Li 6 Si 5The clusters also show good hydrogen storage properties. The introduction of Li atoms significantly improves the 5 The hydrogen storage capacity of the cluster is that three hydrogen molecules can be effectively adsorbed around each Li atom, and the hydrogen storage density can reach 16.617wt%;

[0007] In summary, cluster hydrogen storage technology has high potential and application prospects, especially in the use of cluster materials modified with different elements.

[0008] The Chinese patent application document with publication number CN216923979U discloses a hydrogen storage tank, including a tank shell, a filling layer, a connecting column, a tank liner, an aramid flame retardant layer, an LCP electrical insulation layer, and a glass fiber interlaced layer. The tank shell and the tank liner are both sealed cavity structures. The tank shell is provided with a tank liner, a filling layer is provided between the tank liner and the tank shell, and a connecting column is provided in the filling layer. One end of the connecting column is connected to the tank shell and the other end is connected to the tank liner. The tank liner is fixedly connected to the tank shell by the connecting column. The connecting column plays a supporting role, the pressure release valve passes through the tank shell and is connected to the tank body. The tank shell is provided with an aramid flame retardant layer, the inner wall of the tank body is provided with an LCP electrical insulation layer, and the outer wall of the tank body is provided with a glass fiber interlaced layer. First, hydrogen is injected into the tank body for storage to facilitate transportation. When the tank body is hit during transportation and the transport vehicle catches fire and burns the tank shell, the glass fiber interlaced layer on the outer wall of the tank body can prevent the tank body from exchanging heat with the outside while maintaining the hydrogen temperature, thereby preventing the hydrogen from burning due to heat.

[0009] In the above technology, when the cluster hydrogen storage tank is storing hydrogen, the hydrogen cannot be stably output from the hydrogen storage tank, resulting in poor use of the hydrogen storage tank, and the hydrogen filling efficiency is low when the cluster hydrogen storage tank is filled with hydrogen. Summary of the invention

[0010] The present invention provides a cluster hydrogen storage pressure stabilization device, which aims to solve the technical problems in the prior art that, during the process of storing hydrogen, the cluster hydrogen storage tank cannot output hydrogen stably from the hydrogen storage tank, resulting in poor use effect of the hydrogen storage tank, and the hydrogen filling efficiency is low when the cluster hydrogen storage tank is filled with hydrogen.

[0011] A cluster hydrogen storage pressure stabilization device of the present invention comprises a cluster hydrogen storage tank, a hydrogen discharge port is arranged at the top of the cluster hydrogen storage tank, a stabilization mechanism is arranged on the cluster hydrogen storage tank, the stabilization mechanism comprises a buffer tank arranged on the cluster hydrogen storage tank and a hydrogen discharge pipe arranged on the buffer tank, a connecting pipe is arranged on the buffer tank at the hydrogen discharge port, the connecting pipe is connected with the hydrogen discharge port, a control valve is arranged on the connecting pipe, a buffer cavity is arranged in the buffer tank, the buffer cavity is connected with the connecting pipe, a plurality of hydrogen filling ports are arranged at the bottom of the cluster hydrogen storage tank, the plurality of hydrogen filling ports are arranged at intervals along the circumference of the cluster hydrogen storage tank, a hydrogen filling joint for filling hydrogen into the cluster hydrogen storage tank is arranged in the hydrogen filling port, and a clamping device for clamping the hydrogen filling joint is arranged in the cluster hydrogen storage tank.

[0012] By adopting the above technical scheme and setting a stabilizing mechanism, when the cluster hydrogen storage tank discharges hydrogen through the hydrogen discharge port, the control valve opens, and the hydrogen can pass through the connecting pipe and enter the buffer cavity. After passing through the buffer cavity, the hydrogen is discharged through the hydrogen discharge pipe. The hydrogen can be output stably, thereby improving the use effect of the cluster hydrogen storage tank. At the same time, through the setting of the hydrogen filling connector and multiple hydrogen filling ports, the cluster hydrogen storage tank can be quickly filled with hydrogen.

[0013] Preferably, a limiting ring for limiting the position of the buffer tank is provided on the cluster hydrogen storage tank, and the buffer tank is located inside the limiting ring.

[0014] By adopting the above technical solution and setting a limiting ring, the buffer tank can be limited, thereby preventing the buffer tank from being displaced in the horizontal direction during use.

[0015] Preferably, the cluster hydrogen storage tank comprises an inner shell and an outer shell fixedly mounted on the inner shell, a temperature regulating chamber is provided between the inner shell and the outer shell, and a regulating device for regulating the temperature inside the inner shell is provided on the temperature regulating chamber.

[0016] By adopting the above technical solution and setting up the temperature regulating chamber and the regulating device, when the external temperature changes, the temperature inside the inner shell can be regulated, thereby avoiding a significant impact of changes in the external environment on the use of the cluster hydrogen storage tank.

[0017] Preferably, the clamping device includes a clamping plate for fixing, clamping and unlocking the hydrogen filling joint, an adjusting mechanism for driving the clamping plate to adjust, and a driving mechanism for driving the adjusting mechanism to move, and the clamping plate is slidably fitted in the cluster hydrogen storage tank.

[0018] By adopting the above technical solution, when the driving mechanism moves, it can drive the adjustment mechanism to move, and then drive multiple clamping plates to fix and clamp the hydrogen charging joint, thereby reducing the pressure in the cluster hydrogen storage tank during the hydrogen charging process. When the pressure in the cluster hydrogen storage tank is high, the force applied to the hydrogen charging joint makes the connection between the hydrogen charging joint and the hydrogen charging port unstable, resulting in poor hydrogen charging efficiency.

[0019] Preferably, the adjustment mechanism includes a slider slidably fitted on the cluster hydrogen storage tank and an elastic member for driving the slider to move close to the inner wall of the cluster hydrogen storage tank, one end of the elastic member is connected to the slider, and the other end is connected to the cluster hydrogen storage tank.

[0022] By adopting the above technical scheme and setting the rotating device, when the rotating rod is rotated, the gear two can be driven to rotate, and the gear two can drive the gear one to rotate. When the gear one rotates, the clamping plate is squeezed, and the clamping plate slides toward the hydrogen charging joint, thereby realizing the squeezing and locking of the hydrogen charging joint by the clamping plate. When the rotating rod does not rotate, the locking mechanism squeezes and locks the rotating rod, thereby reducing the rotation of the rotating rod, thereby improving the clamping stability of the clamping plate on the hydrogen charging joint. At the same time, when the gear two rotates, multiple gears one can be driven to rotate at the same time, thereby realizing the adjustment of the positions of multiple groups of clamping plates, making the clamping of multiple hydrogen charging joints more efficient.

[0023] Preferably, the locking mechanism includes a mounting sleeve mounted on the cluster hydrogen storage tank, a ratchet connected to the rotating rod, a pawl rotatably matched with the ratchet, and an adjustment assembly for driving the pawl for rotational adjustment, and the ratchet is adapted to the pawl.

[0024] Preferably, the adjustment assembly includes a pressing rod that is slidably matched with the mounting sleeve and is used to press one end of the pawl, and an elastic sheet that is used to drive the pawl to press against the ratchet wheel.

[0025] The beneficial effects of the present invention are:

[0026] 1. In the present invention, through the setting of the stabilizing mechanism, when the cluster hydrogen storage tank discharges hydrogen through the hydrogen discharge port, the control valve is opened, and the hydrogen can pass through the connecting pipe and enter the buffer cavity. After passing through the buffer cavity, it is discharged through the hydrogen discharge pipe, so that the hydrogen can be stably output, thereby improving the use effect of the cluster hydrogen storage tank.

[0027] 2. In the present invention, by setting the hydrogen filling joint and multiple hydrogen filling ports, the rapid hydrogen filling operation of the cluster hydrogen storage tank can be realized. By setting the clamping device, when the driving mechanism moves, it can drive the adjustment mechanism to move, and then drive the multiple clamping plates to fix and clamp the hydrogen filling joint, thereby reducing the force applied to the hydrogen filling joint when the pressure in the cluster hydrogen storage tank is high during the hydrogen filling process into the cluster hydrogen storage tank, making the connection between the hydrogen filling joint and the hydrogen filling port unstable, resulting in poor hydrogen filling efficiency;

[0028] 3. In the present invention, by setting the rotating device, when the rotating rod is rotated, it can drive gear two to rotate, and gear two can drive gear one to rotate. When gear one rotates, the clamping plate is squeezed, and the clamping plate slides toward the hydrogen charging joint, thereby realizing the squeezing and locking of the hydrogen charging joint by the clamping plate. When the rotating rod does not rotate, the locking mechanism squeezes and locks the rotating rod, reducing the rotation of the rotating rod, thereby improving the clamping stability of the clamping plate on the hydrogen charging joint. At the same time, when gear two rotates, it can drive multiple gears one to rotate at the same time, thereby realizing the adjustment of the position of multiple groups of clamping plates, making the clamping of multiple hydrogen charging joints more efficient.

When the clamping plate 61 slides, it drives the slider 621 to slide and stretches the elastic member 622. When the gear 1 631 rotates in the opposite direction, it can drive the extrusion block 632 to rotate, and the extrusion block 632 moves away from the clamping plate 61 and no longer squeezes the clamping plate 61. At this time, the elastic member 622 releases its elastic restoring force, drives the slider 621 to slide, drives the clamping plate 61 to slide, and performs the reset operation.

[0045] Reference Figure 2-Figure 5 A rotating device 7 is provided on the cluster hydrogen storage tank 1, and the rotating device 7 includes a gear 2 71 for driving the gear 1 631 to rotate, a rotating rod 72 for driving the gear 2 71 to rotate, and a locking mechanism 73 for squeezing, locking and unlocking the rotating rod 72.

[0046] Reference Figure 2-Figure 5The locking mechanism 73 includes a mounting sleeve 731 fixedly mounted on the cluster hydrogen storage tank 1, a ratchet 732 fixedly connected to the rotating rod 72, a pawl 733 rotatably matched with the ratchet 732, and an adjusting component for driving the pawl 733 to perform rotational adjustment. The ratchet 732 is rotatably matched in the mounting sleeve 731, the ratchet 732 is adapted to the pawl 733, a rotating shaft is fixedly mounted at the middle position of the pawl 733, the rotating shaft is rotatably matched with the mounting sleeve 731, the pawl 733 is rotatably matched with the mounting sleeve 731 through the rotating shaft, and the adjusting component includes a sliding match with the mounting sleeve 731 and used to adjust one end of the pawl 733 The pressing rod 734 for squeezing and the elastic sheet 735 for driving the pawl 733 to press against the ratchet 732, the pressing rod 734 is a "T"-shaped rod, and the end of the pressing rod 734 close to the pawl 733 is set to a circle, and the squeezing rod 734 is abutted against the inner wall of the mounting sleeve 731 and a ring is fixedly set thereon, and the ring abuts against the inner wall of the mounting sleeve 731 to prevent the squeezing rod 734 from slipping out of the mounting sleeve 731, and the elastic sheet 735 is set to an "S" shape, one end of the elastic sheet 735 is fixedly connected to the inner wall of the mounting sleeve 731, and the other end of the elastic sheet 735 abuts against the end of the pawl 733 away from the pressing rod 734.

[0047] Reference Figure 2-Figure 5 , press the pressing rod 734, and the pressing rod 734 slides toward the ratchet 732. The pressing rod 734 squeezes the pawl 733, causing the end of the pawl 733 that is away from the pressing rod 734 to rotate in the direction away from the ratchet 732 and compress the elastic sheet 735. At this time, the pawl 733 is no longer locked to the ratchet 732. When the pawl 733 is no longer locked to the ratchet 732, the rotating rod 72 is rotated, and the rotating rod 72 drives the gear 2 71 to rotate.

[0048] The implementation principle of a cluster hydrogen storage pressure stabilization device of the present invention is as follows: when the cluster hydrogen storage tank 1 needs to be used, hydrogen is first charged into the cluster hydrogen storage tank 1. When charging hydrogen, the plurality of hydrogen charging connectors 5 are first inserted into the plurality of hydrogen charging ports 16 respectively, and then the pressing rod 734 is pressed, and the pressing rod 734 slides toward the ratchet 732, and the pressing rod 734 squeezes the ratchet 733, so that the end of the ratchet 733 away from the pressing rod 734 rotates in a direction away from the ratchet 732, and compresses the elastic sheet 735;

[0049] When the pawl 733 is no longer locked to the ratchet wheel 732, the rotating rod 72 is rotated, and the rotating rod 72 drives the gear 2 71 to rotate. When the gear 2 71 rotates, it can drive multiple gears 1 631 to rotate at the same time. When the gear 1 631 rotates, it can drive the extrusion block 632 to rotate. The extrusion slope 633 of the extrusion block 632 can squeeze the clamping plate 61, so that the clamping plate 61 slides toward the hydrogen charging joint 5. When the clamping plate 61 slides, it drives the slider 621 to slide and stretches the elastic member 622. When the clamping plate 61 squeezes and locks the hydrogen charging joint 5, the pressing rod 734 is no longer pressed. At this time, the elastic sheet 735 releases its elastic restoring force, driving the pawl 733 to rotate. The pawl 733 is pressed tightly against the ratchet wheel 732, and the rotating rod 72 cannot rotate at this time.

[0050] After the hydrogen charging connector 5 is fixed at the hydrogen charging port 16, hydrogen is then charged into the cluster hydrogen storage tank 1 through the hydrogen charging connector 5. After the hydrogen charging is completed, the hydrogen is stored in the cluster hydrogen storage tank 1. When the hydrogen needs to be output, the control valve 3 is opened, and the hydrogen can enter the buffer cavity 212 through the hydrogen discharge port 11 and the connecting pipe 211, and then be discharged through the hydrogen discharge pipe 22;

[0051] When the hydrogen charging connector 5 needs to be disassembled, the pressing rod 734 is pressed, and the pressing rod 734 slides toward the ratchet 732. The pressing rod 734 squeezes the pawl 733, so that the end of the pawl 733 away from the pressing rod 734 rotates in the direction away from the ratchet 732 and compresses the elastic sheet 735. When the pawl 733 no longer locks the ratchet 732, the rotating rod 72 is rotated in the opposite direction. The rotating rod 72 drives the gear 2 71 to rotate. When the gear 2 71 rotates, it can drive multiple gears 1 631 to rotate at the same time. When the gear 1 631 rotates, it can drive the extrusion block 632 to rotate.

[0052] The squeezing block 632 moves away from the clamping plate 61 and no longer squeezes the clamping plate 61. At this time, the elastic member 622 releases its elastic restoring force, driving the slider 621 to slide, driving the clamping plate 61 to slide, and performing a reset operation. After the clamping plate 61 no longer squeezes and locks the hydrogen charging connector 5, the hydrogen charging connector 5 is removed from the hydrogen charging port 16. After removal, the pressing rod 734 is no longer pressed. At this time, the elastic sheet 735 releases its elastic restoring force, driving the pawl 733 to rotate, and the pawl 733 is pressed tightly against the ratchet 732. At this time, the rotating rod 72 cannot rotate, and the disassembly operation of the hydrogen charging connector 5 is completed.
