Description

Technical Field

[0001] The present invention relates to the technical field of pressurized gas storage, and in particular to a high-pressure hydrogen storage tank container group. Background Art

[0002] Hydrogen storage tanks are commonly used pressure vessels for storing hydrogen. Existing hydrogen storage tubes have a slender structure. At the same time, due to the flammable and explosive properties of hydrogen, electrical equipment is avoided as much as possible in its exhaust control system.

[0003] Traditional hydrogen storage tank exhaust mainly relies on the opening and closing of manual valves. At the same time, in order to adapt to different production requirements and purchasing needs, the sizes of most hydrogen storage tanks connected in series are not completely uniform. When exhausting, the pressure at the gas outlet end is much greater than that at the gas consumption end. The switching of the switches when exhausting in sequence can easily lead to large pressure fluctuations, which is not in line with the production process. If they are opened at the same time, after the small hydrogen storage is quickly exhausted, backflow will occur, affecting the gas outlet efficiency and pressure, and it is difficult to control the subsequent closing of the valve. Summary of the Invention

At the same time, the semicircular baffle pushes the rotating block to move toward the driving motor.

[0011] In one embodiment, the main frame includes a plurality of stacked support frames, a plurality of support slides are provided on the support frames, a plurality of tank protection racks are provided between the plurality of support slides, and the gas storage tank is provided above the tank protection racks.

Meshing racks of several lengths are provided on the outer side of the rotating belt, and the meshing racks mesh with adjacent meshing gears.

[0017] The beneficial effects of the present invention are as follows: the present invention is a high-pressure hydrogen storage tank container group that effectively realizes rapid exhaust of hydrogen storage tanks of different sizes and prevents other backflows. The specific implementation method is as follows:

[0018] When the air in the air tank is exhausted, the air in the air tank at the rear end can only flow through the supplementary flow channel 1 or the supplementary flow channel 2. During the exhaust process, the gas pressure of the first exhaust gas tank gradually decreases, which may gradually fail to meet the pressure demand of the terminal gas user. Therefore, the subsequent air tanks need to be exhausted at the same time, and the auxiliary pressure is stable. The gas in the subsequent air tanks flows to the main frame through the supplementary flow channel 2 for air replenishment. Since the outflow pressure of the supplementary flow channel 2 and the gas flow channel 1 is much greater than that of the outlet end, the supplementary gas will not flow back to the front air tank with lower pressure.

[0019] At the same time, the pressure of the front air tank will produce a linear decay when exhausting, so the rear air tank is needed to increase the exhaust volume: start the drive motor to drive the threaded rod to rotate. When the threaded rod rotates, the semicircular baffle engages to drive the sliding exhaust pipe to move horizontally in the auxiliary air pipe. At the same time, the semicircular baffle pushes the rotating block to move toward the drive motor. During the movement of the rotating block, the guide rod engages the arc-shaped periodic wave groove on the auxiliary air pipe to generate rotation, driving the change of the ventilation volume of the supplementary air channel 1 and the supplementary air channel 2, resulting in the following two implementation processes:

[0020] First, the first supply channel expands, and the gas from the subsequent gas tank flows into the first supply channel through the first supply channel. At the same time, the second supply channel gradually shrinks. At this time, the gas pressure of the gas tank close to the vent opening gradually decreases and is about to be equal to the supply pressure. The gas tank close to the rotating block gradually begins to take on the main gas supply task. After moving to the vent opening, the previous gas tank is blocked by the long tube of the sliding vent pipe to prevent the pressurized gas from flowing back. The above gas supply process can be repeated.

[0021] Second, the expansion of the second supplementary gas flow channel indicates that the gas supply pressure at the front end is sufficient. Even if the second supplementary gas flow channel expands, the amount of gas added is relatively small. This is mainly for the preliminary preparation process of the first implementation process to avoid the small gas tank pressure dropping too quickly and the gas supply being insufficient.

[0022] By cyclically alternating the first and second implementation processes, the gas pressure can be kept relatively stable while avoiding the problems of gas backflow and pressure drop caused by inconsistent gas tank sizes.

[0023] When the air filter is turned on, the air filter will be turned off, and the air filter will be turned off immediately. When the cam is in a closed position, the cam is released, and the cam is released to the left, and the cam is in a closed position, so that the cam is in a closed position and the cam is in a closed position, so that the cam is in a closed position and the cam is in a closed position.

[0024] At the same time, a measuring device is installed in the bypass branch pipe of the measuring component. For example, the measuring device is a pressure gauge, which can more clearly understand the changes in the real-time pressure of the equipment and better control the tank group.

[0025] The device has a simple structure and uses the pressure of the gas to effectively seal the gas tank. At the same time, the sliding vent pipe slides in the auxiliary air pipe to effectively change the control of the gas discharge volume of gas tanks with different pressures, avoiding the problems of gas backflow and pressure switching. It has good practicality and economy, and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The driving motor 34 is provided at the blocked end of the air outlet pipe 33, and a threaded rod 35 is provided at the center position of the circle in the middle of the air outlet pipe 33. The driving motor 34 drives the threaded rod 35 to rotate, and the threaded rod 35 passes through and is rotatably connected to the semicircular baffle 374. A supporting sliding block 37101 is provided in the circular tube of the sliding air release pipe 37 away from the air release opening 371, and the threaded rod 35 passes through and is slidably connected to the supporting sliding block 37101.

Specifically, it can be achieved by a rotating groove or a bearing. It is a prior art and will not be described in detail. Not shown, the outer side of the rotating block 373 is provided with an air replenishing notch 37301, the air replenishing notch 37301 is provided with an arc-shaped air replenishing groove 37302 at the symmetrical position of the central axis of the rotating block 373, the rotating block 373 is provided with a guide rod 37303 on the outer side of the arc-shaped air replenishing groove 37302, and the auxiliary air pipe 36 is provided with an arc-shaped periodic wave groove 361 on the side close to the guide rod 37303, and the periodic width is referred to between the two sets of ventilation connecting pipes 31. The rotating block 373 is introduced into and slidably connected to the arc-shaped periodic wave groove 361. The gas flows through the air-supply gap 37301 to the gap between the semicircular baffle 374 and the sliding air release pipe 37 to form a supplementary flow channel 1. The gas flows through the arc-shaped air-supply groove 37302 to the gap between the semicircular baffle 374 and the sliding air release pipe 37 to form a supplementary flow channel 2. The supplementary flow channel 1 and the supplementary flow channel 2 are connected to the gas flow channel 1, and the ventilation volume of the supplementary flow channel 1 and the supplementary flow channel 2 are inversely proportional.

[0044] In practice, during the movement of the rotating block 373, the guide rod 37303 engages the arc-shaped periodic wave groove 361 on the auxiliary air tube 36 to generate rotation, driving the change of the ventilation volume of the supplementary air flow channel 1 and the supplementary air flow channel 2, resulting in the following two implementation processes:

[0045] First, the first supply channel expands, and the gas from the subsequent gas tank 2 flows into the first supply channel through the first supply channel, while the second supply channel gradually shrinks. At this time, the gas pressure of the gas tank 2 near the vent opening 371 gradually decreases, and is about to equalize with the supply pressure. The gas tank 2 near the rotating block 373 gradually begins to take on the main gas supply task. After moving to the vent opening 371, the previous gas tank 2 is blocked by the long tube of the sliding vent pipe 37, preventing the pressurized gas from flowing back. The above gas supply process can then be repeated.

[0046] Second, the expansion of the supplementary gas flow channel 2 indicates that the gas supply pressure at the front end is sufficient. Even if the supplementary gas flow channel 2 is expanded, the amount of gas supplemented is relatively small. This is mainly for the preliminary preparation process of the first implementation process to avoid the small gas storage tank 2 pressure dropping too quickly and the gas supply being insufficient.

[0047] Reference Figure 9 、 10 As shown, it is beneficial that a main control valve 32 is provided in the middle of the ventilation connecting pipe 31, and a closing mechanism 5 is provided in the middle of the ventilation connecting pipe 31 between the main control valve 32 and the outlet pipe 33. The closing mechanism 5 includes an air baffle 523, and the air baffle 523 is provided in the inner cavity of the ventilation connecting pipe 31. A rotating nail plate 53 is provided on the outer side of the ventilation connecting pipe 31. The rotating nail plate 53 passes through and is rotatably connected to the ventilation connecting pipe 31 and is fixed to the air baffle 523. A plurality of fixing holes 531 are provided on the rotating nail plate 53. The ventilator 51 further includes a long rod of a rotating nail plate 53 which passes through and is rotatably connected to the ventilator 51. The outer peripheral side of the rotating disk of the rotating nail plate 53 abuts against the inner cavity of the ventilator 51. The ventilator 51 is further provided with a rotating rod 52. One end of the rotating rod 52 is provided with a meshing gear 521. The other end of the rotating rod 52 passes through the ventilator 51 and is provided with a meshing disk 54. The meshing disk 54 is provided with a protrusion which meshes with the fixing hole 531. The meshing disk 54 abuts against the inner cavity of the ventilator 51. The meshing disk 54 and the inner cavity of the ventilator 51 are combined. A second connecting air pipe 512 is provided between the rotating nail plate 53 and the inner cavity of the ventilator 51, which is connected to the ventilation connecting pipe 31. A disconnect assembly is provided between the rotating rod 52 and the engaging disk 54. The disconnect assembly includes a lifting tube 524, which is inserted into and slidably connected to the rotating rod 52. A movable column 541 is provided in the middle of the engaging disk 54. The movable column 541 is inserted into and slidably connected to the lifting tube 524. There is a movable column 541 on the movable column 541. Slot 542, a long lever 543 is provided on the lifting tube 524, the long lever 543 passes through the movable slot 542 and abuts against the inner cavity of the ventilator 51, the inner cavity of the ventilator 51 is also provided with a wedge-shaped lifting block 513, a rotating belt 552 is provided on one side of the plurality of meshing gears 521, and the two ends of the rotating belt 552 are driven to rotate by a rotating support rod 55 with a rotating disk 551, and a meshing rack 553 of several lengths is provided on the outer side of the rotating belt 552, and the meshing rack 553 meshes with the adjacent meshing gears 521.

[0048] In practice, when the pressure of the auxiliary air pipe 36 connected to the second connecting air pipe 512 is lower than that of the gas tank 2 connected to the first connecting air pipe 511, the gas in the first connecting air pipe 511 pushes the meshing plate 54 to move upward, disengaging the meshing plate 54 from engaging the rotating nail plate 53. Therefore, when the rotating rod 52 rotates, it will not affect the air baffle plate 523, that is, it will not hinder the gas tank 2 from ventilating the auxiliary air pipe 36. If the pressure of the auxiliary air pipe 36 connected to the second connecting air pipe 512 is higher than that of the gas tank 2 connected to the first connecting air pipe 511, the gas pushes the meshing plate 54 to move downward, and the long The rod 543 gradually disengages from the movable groove 542 on the movable column 541, allowing the engaging disk 54 to engage with the fixed hole 531. Then, when the rotating rod 52 rotates, it drives the rotating nail plate 53 below the engaging disk 54 and the air baffle plate 523 to rotate and block the ventilation connecting pipe 31. Before the blocking is completed, the long rod 543 is moved to contact the wedge-shaped lifting block 513 and lift it upward. After the blocking is complete, the lifting tube 524 on the long rod 543 is moved to slide upward so that the long rod 543 is disengaged from the movable groove 542, so that the position of the air baffle plate 523 can be partially affected when the rotating rod 52 rotates subsequently.

[0049] Working principle of the present invention:

[0050] The operator first places the gas tank 2 on the tank protection rack 12, and then connects the ventilation connecting pipe 31 to complete the gas supply. At the same time, when facing gas tanks 2 of different lengths, the tank protection rack 12 is slid on the support slide 13 to change the support position to match different gas tanks 2. When exhaust is required, the main control valve 32 is opened in sequence, and the gas in the gas tank 2 flows through the gas flow channel and is discharged from one end of the outlet pipe 33. At the same time, the outlet pipe 33 has only one outlet. When the gas tank 2 exhausted at the front end is exhausted, the rear end The gas tank 2 can only flow through the supplementary flow channel 1 or the supplementary flow channel 2. Since the gas pressure of the gas tank 2 that is exhausted first gradually decreases during the exhaust process, it may gradually be unable to meet the pressure demand of the terminal gas user. Therefore, the subsequent gas tanks 2 need to be exhausted at the same time to stabilize the auxiliary pressure. The gas from the subsequent gas tanks 2 flows to the main frame 1 through the supplementary flow channel 2 for gas replenishment. Since the outflow pressure of the supplementary flow channel 2 and the gas flow channel 1 is much greater than that of the gas outlet, the supplementary gas will not flow back to the gas tank 2 with lower pressure at the front end;

[0051] At the same time, the pressure of the front air tank 2 will produce a linear decay when exhausting, so the rear air tank 2 needs to increase the exhaust volume: start the drive motor 34 to drive the threaded rod 35 to rotate. When the threaded rod 35 rotates, the meshing semicircular baffle 374 drives the sliding air release pipe 37 to move horizontally in the auxiliary air pipe 36. At the same time, the semicircular baffle 374 pushes the rotating block 373 to move toward the drive motor 34. During the movement of the rotating block 373, the guide rod 37303 engages the arc-shaped periodic wave groove 361 on the auxiliary air pipe 36 to rotate, driving the change of the ventilation volume of the supplementary air channel 1 and the supplementary air channel 2, resulting in the following two implementation processes:

[0052] First, the first supply channel expands, and the gas from the subsequent gas tank 2 flows into the first supply channel through the first supply channel, while the second supply channel gradually shrinks. At this time, the gas pressure of the gas tank 2 near the vent opening 371 gradually decreases, and is about to equalize with the supply pressure. The gas tank 2 near the rotating block 373 gradually begins to take on the main gas supply task. After moving to the vent opening 371, the previous gas tank 2 is blocked by the long tube of the sliding vent pipe 37, preventing the pressurized gas from flowing back. The above gas supply process can then be repeated.

[0053] Second, the expansion of the supplementary gas flow channel 2 indicates that the gas supply pressure at the front end is sufficient. Even if the supplementary gas flow channel 2 is expanded, the amount of gas supplemented is relatively small. This is mainly for the preliminary preparation process of the first implementation process to avoid the small gas storage tank 2 pressure dropping too quickly and the gas supply being insufficient.

[0054] By cyclically alternating the first and second implementation processes, the gas pressure can be kept relatively stable with minimal fluctuations, while also avoiding the problems of gas backflow and sudden pressure drops caused by inconsistent sizes of the gas storage tanks 2.

[0055] In order to prevent the operator from manually closing the main control valve 32 when sliding the air release pipe 37 to block the ventilation connecting pipe 31 of the air storage tank 2, resulting in backflow and other problems, the ventilation connecting pipe 31 is blocked by controlling the internal and external pressure difference between the air storage tank 2 and the auxiliary air pipe 36. When the pressure of the auxiliary air pipe 36 connected to the second connecting air pipe 512 is lower than that of the air storage tank 2 connected to the first connecting air pipe 511, the gas in the first connecting air pipe 511 pushes the meshing disk 54 to move upward and disengages the meshing disk 54 from engaging the rotating nail plate 53. Therefore, when the rotating rod 52 rotates, it will not affect the air baffle plate 523, that is, it will not hinder the air storage tank 2 from ventilating the auxiliary air pipe 36. If the pressure of the auxiliary air pipe 36 connected to the second connecting air pipe 512 is higher than that of the air storage tank 2 connected to the first connecting air pipe 511, the gas pushes the meshing disk 54 to move downward. When the cam 53 is in the airtight position, the cam 532 is in the airtight position, and the cam 533 is in the airtight position, so that the cam 533 is in the airtight position.
