Description

Technical Field

[0001] The invention belongs to the technical field of hydrogen energy equipment, and in particular relates to a bottle changing storage cabinet for hydrogen energy gaseous hydrogen storage bottles. Background Art

[0002] Hydrogen energy gaseous hydrogen storage bottles are a very important link in the hydrogen energy industry chain, mainly used for the storage and transportation of hydrogen. Gaseous hydrogen storage bottles have a wide range of applications, including fuel cell vehicles, hydrogen refueling stations, laboratories, etc. After the hydrogen in the gaseous hydrogen storage bottle is consumed, it needs to be replaced, and then it can be recycled after being filled with hydrogen. However, due to the nature of hydrogen, hydrogen storage bottles have potential risks during the process of gas exchange and storage. The gaseous hydrogen storage bottle exchange storage cabinet is a safety device specially designed for storing and replacing gaseous hydrogen storage bottles, which can effectively reduce potential risks.

[0003] Although the traditional gaseous hydrogen bottle exchange storage cabinet has a ventilation mechanism that can exchange air and a frame that can place the hydrogen bottle, it can reduce certain risks. However, during the most dangerous inflation process, the cabinet door needs to be opened manually to connect the hydrogen bottle and the ventilation mechanism, and the protective performance cannot be well exerted; at the same time, during the replacement of the hydrogen bottle, the bottle mouth and the ventilation mechanism of the hydrogen bottle are weak points of protection. Once a collision occurs, an accident is very likely to occur, and the hydrogen bottle cannot be guaranteed to be firmly installed in the placement frame, which has certain safety hazards. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a storage cabinet for hydrogen energy gaseous hydrogen storage bottles. The present invention can operate the connection between the gas cylinder and the ventilation mechanism when the cabinet door is closed, thereby enhancing the safety protection of the operator. The gas cylinder can be directly stuck in the cylinder frame and can ensure that the gas cylinder is placed in the middle of the cylinder frame, which is helpful for the docking of the gas cylinder and the ventilation mechanism. During the replacement of the gas cylinder, the gas cylinder is away from the ventilation mechanism to prevent the gas cylinder from colliding with the ventilation mechanism, thereby preventing danger.

[0005] The technical solution adopted to solve the above technical problems is: a storage cabinet for hydrogen energy gaseous hydrogen storage bottles, comprising a cabinet, a storage bottle frame, a ventilation mechanism, a cabinet door, a gas storage bottle and a gas collecting hood, wherein the storage bottle frame is slidably connected in the cabinet, the cabinet door is hinged on the front side of the cabinet, the gas collecting hood is fixedly arranged on the rear side of the cabinet, the ventilation mechanism is arranged above the inside of the cabinet, and a crimping mechanism is slidably connected to the cabinet door;

[0006] The gas storage bottle can be clamped in the bottle storage frame, and the ventilation mechanism is arranged above the bottle storage frame;

[0009] The crimping mechanism can drive the ventilation joint to slide vertically when it slides vertically on the cabinet door.

[0010] Through the above technical solution, when the gas cylinder needs to be replaced, the cabinet door is opened to pull out the cylinder frame, and then the gas cylinder is clamped in the cylinder frame, and then the cylinder frame is pushed back. The replacement can be completed by closing the cabinet door. The replacement process is outside the cabinet, and the gas cylinder will not collide with the mechanism inside the cabinet, ensuring the safety of the replacement. After closing the cabinet door, the crimping mechanism can be operated to drive the connection between the gas exchange joint and the gas cylinder, so that the connection operation is performed outside the cabinet and protected by the cabinet. Even if the gas cylinder leaks or other faults, it will not endanger the operator, which strengthens the safety protection of the operator. The gas collection hood can be connected to the gas collection device to absorb the gas in the cabinet, which can effectively deal with the leakage of the gas cylinder.

The air joint is communicated with the ventilation joint, and the ventilation joint can be clamped on the bottle mouth at the top of the gas storage bottle. The bottom of the bracket is symmetrically fixedly connected with a third rack.

[0018] Through the above technical scheme, since the ventilation joint is vertically slidably connected under the bracket, the ventilation joint is connected to the bracket through a telescopic air guide tube, the top of the cabinet is fixedly connected with a gas guide joint, the gas guide joint is connected to the bracket through a telescopic air guide tube, the gas guide joint is communicated with the ventilation joint, and the ventilation joint can be clamped on the bottle mouth at the top of the gas bottle, so that the gas guide joint can be connected to the charging device. After the ventilation joint is connected to the bottle mouth at the top of the gas bottle, the charging device can be turned on to inflate the gas bottle, and the charging device is separated from the cabinet, which effectively ensures the safety of the cabinet and improves the safety during inflation.

[0019] Furthermore, a second rack is fixedly connected to the top of the bottle storage frame, and gears are symmetrically rotatably connected on both sides of the cabinet. The gears are arranged between the second rack and the third rack, the second rack is meshed with the bottom of the gear, and the third rack is meshed with the top of the gear.

[0020] Through the above technical scheme, since the second rack is fixedly connected to the top of the bottle storage frame, gears are symmetrically rotatably connected on both sides of the cabinet, and the gears are arranged between the second rack and the third rack, the second rack is meshed with the bottom of the gear, and the third rack is meshed with the top of the gear, so that when the gears rotate, the second rack and the third rack slide horizontally in opposite directions, and then when the bottle storage frame is pulled out, the ventilation mechanism slides in the opposite direction, and when the bottle storage frame is pulled out to load and unload the gas cylinder, the gas cylinder will not collide with the ventilation mechanism, thereby avoiding the occurrence of danger, and after the loading and unloading of the bottle storage frame is completed, when the bottle storage frame is pushed back into the cabinet, the ventilation mechanism slides horizontally in the direction close to the bottle storage frame, and finally when the bottle storage frame returns to its original position, the ventilation mechanism just returns to the top of the bottle storage frame.

[0021] Furthermore, the cabinet door includes a fixed plate, a force storage spring and a slide groove. The top outer side of the cabinet door is fixedly connected to a fixed plate, the bottom of the fixed plate is fixedly connected to a force storage spring, the bottom of the force storage spring is fixedly connected to a crimping mechanism, a slide groove is provided below the fixed plate on the cabinet door, and the crimping mechanism is slidably connected to the slide groove.

[0024] Through the above technical scheme, since the fork passes through the slide groove and is arranged on the inner side of the cabinet door, the blocking plate is arranged on the outer side of the cabinet door, the blocking plate can block the slide groove, the blocking plate passes through the fixed plate, and the handle is arranged on the outer side of the cabinet door, the fork can be clamped in the ventilation joint, so that when the cabinet door is closed, the handle is pulled down to press the crimping mechanism, so that the fork can drive the ventilation joint to descend, and then the ventilation joint is connected to the bottle mouth at the top of the gas storage bottle. After releasing the handle, the force storage spring can drive the crimping mechanism to rise, and the fork can drive the ventilation joint to rise, and then the ventilation joint is disconnected from the bottle mouth at the top of the gas storage bottle, thereby realizing the connection procedure outside the cabinet door and effectively protecting the operator.

[0025] Furthermore, the gas collecting hood is connected to the cabinet.

[0026] Through the above technical solution, the gas collecting hood and the cabinet are connected, and the gas collecting hood is connected to the gas collecting device. During the process of inflating the gas cylinder, a small amount of hydrogen leakage can be discharged through the gas collecting hood, which effectively enhances the safety of inflating the gas cylinder and prevents hydrogen from being enriched in the cabinet, thereby avoiding the occurrence of danger. Even if the gas cylinder explodes or other dangerous faults occur, the explosion impact will first spread toward the gas collecting hood, reducing the impact on the cabinet door, and effectively protecting the operator.

[0047] The gas storage bottle 6 can be clamped in the bottle storage frame 2, and the gas exchange mechanism 3 is arranged above the bottle storage frame 2;

[0048] The bottle storage frame 2 slides horizontally in the cabinet 1 and can drive the ventilation mechanism 3 to slide horizontally in the cabinet 1;

[0049] A ventilation joint 31 is slidably connected to the ventilation mechanism 3, and the ventilation joint 31 can be clamped on the bottle mouth at the top of the gas storage bottle 6;

[0050] The crimping mechanism 5 can slide vertically on the cabinet door 4 to drive the ventilation joint 31 to slide vertically.

[0051] In this embodiment, when the gas cylinder 6 needs to be replaced, the cabinet door 4 is opened to pull out the cylinder frame 2, and then the gas cylinder 6 is clamped in the cylinder frame 2, and then the cylinder frame 2 is pushed back. The replacement can be completed by closing the cabinet door 4. The replacement process is outside the cabinet 1, and the gas cylinder 6 will not collide with the mechanism inside the cabinet 1, ensuring the safety of the replacement. After closing the cabinet door 4, the crimping mechanism 5 can be operated to drive the connection between the gas exchange joint 31 and the gas cylinder 6, so that the connection operation is performed outside the cabinet 1 and protected by the cabinet 1. Even if the gas cylinder 6 leaks or other faults, it will not endanger the operator, thereby strengthening the safety protection of the operator. The gas collection hood 7 can be connected to the gas collection device to absorb the gas in the cabinet 1, and can effectively handle the leakage of the gas cylinder 6.

[0052] like Figure 3 - Figure 5 As shown, the cabinet 1 is symmetrically provided with support rails 12 on both sides, the bottle storage frame 2 is slidably connected to the support rails 12, the bottle storage frame 2 comprises a clamp 21, a support plate 22 and a crossbeam 23, the crossbeam 23 is two symmetrically fixedly connected to both sides of the bottle storage frame 2, the inner side of the crossbeam 23 is fixedly connected to the limited track, the clamp 21 is slidably connected to the limited track on the inner side of the crossbeam 23, and the support plate 22 is slidably connected to the bottom of the bottle storage frame 2;

[0053] A buffer spring 222 is fixedly connected to the bottom of the support plate 22, and the bottom of the buffer spring 222 is fixedly connected to the bottom of the bottle storage frame 2. The first racks 221 are symmetrically fixedly connected to both sides of the support plate 22;

[0054] A threaded rod 211 is fixedly connected to one side of the clamp 21 , and a toothed ring 231 is rotatably connected to the outer side of the beam 23 . The threaded rod 211 passes through the beam 23 and the toothed ring 231 , and the threaded rod 211 is threadedly connected to the toothed ring 231 , and the first rack 221 is meshed with the toothed ring 231 .

[0055] In this embodiment, when the gas cylinder 6 is placed in the cylinder frame 2, the support plate 22 can support the gas cylinder 6. The setting of the buffer spring 222 can reduce the impact on the gas cylinder 6 and enhance the safety of the gas cylinder 6. After supporting the gas cylinder 6, the support plate 22 will drop, and the first rack 221 can drop together with the support plate 22. When the gas cylinder 6 is taken out, the support plate 22 will rise, so that the first rack 221 rises together with the support plate 22.

[0056] The lifting and lowering of the first rack 221 can drive the gear ring 231 to rotate, that is, the lifting and lowering of the support plate 22 can drive the clamp 21 to slide horizontally. When the support plate 22 descends, the first rack 221 can drive the gear ring 231 to rotate forward, and the forward rotation of the gear ring 231 can drive the two clamps 21 to approach each other, so that the two clamps 21 clamp the gas cylinder 6. When the support plate 22 rises, the first rack 221 can drive the gear ring 231 to rotate reversely, and the reverse rotation of the gear ring 231 can drive the two clamps 21 to move away from each other, so that the two clamps 21 release the clamping of the gas cylinder 6.

[0057] like Figure 6 - Figure 8 As shown, guide rails 13 are symmetrically arranged on both sides of the cabinet 1, and the guide rails 13 are arranged above the support rails 12. The ventilation mechanism 3 is slidably connected to the guide rails 13. The ventilation mechanism 3 includes a ventilation joint 31, a bracket 32 ​​and a third rack 33. The ventilation joint 31 is vertically slidably connected below the bracket 32. The ventilation joint 31 is connected to the bracket 32 ​​through a telescopic air guide pipe. The top of the cabinet 1 is fixedly connected with a gas guide joint 11, which is connected to the bracket 32 ​​through a telescopic air guide pipe. The gas guide joint 11 is communicated with the ventilation joint 31. The ventilation joint 31 can be clamped on the bottle mouth at the top of the gas storage bottle 6, and the bottom of the bracket 32 ​​is symmetrically fixedly connected with the third rack 33.

[0058] A second rack 24 is fixedly connected to the top of the bottle storage frame 2, and gears 14 are symmetrically rotatably connected on both sides of the cabinet 1. The gear 14 is arranged between the second rack 24 and the third rack 33. The second rack 24 meshes with the bottom of the gear 14, and the third rack 33 meshes with the top of the gear 14.

[0059] In this embodiment, the gas guide joint 11 can be connected to the charging device. After the gas exchange joint 31 is connected to the bottle mouth at the top of the gas storage bottle 6, the charging device can be turned on to inflate the gas storage bottle 6. The charging device is separated from the cabinet 1, which effectively ensures the safety of the cabinet 1.

[0060] When the gear 14 rotates, the second rack 24 and the third rack 33 slide horizontally in opposite directions, so that when the bottle frame 2 is pulled out, the ventilation mechanism 3 slides in the opposite direction. When the bottle frame 2 is pulled out to load and unload the gas cylinder 6, the gas cylinder 6 will not collide with the ventilation mechanism 3, thereby avoiding the occurrence of danger. After the loading and unloading of the bottle frame 2 is completed, when the bottle frame 2 is pushed back into the cabinet 1, the ventilation mechanism 3 slides horizontally in the direction close to the bottle frame 2. Finally, when the bottle frame 2 returns to its original position, the ventilation mechanism 3 just returns to the top of the bottle frame 2.

[0061] like Figure 8 - Fig.13 As shown, the cabinet door 4 includes a fixed plate 41, a force storage spring 42 and a slide groove 43. The top of the outer side of the cabinet door 4 is fixedly connected with the fixed plate 41, the bottom of the fixed plate 41 is fixedly connected with the force storage spring 42, the bottom of the force storage spring 42 is fixedly connected with the crimping mechanism 5, and a slide groove 43 is provided below the fixed plate 41 on the cabinet door 4, and the crimping mechanism 5 is slidably connected with the slide groove 43;

[0062] The crimping mechanism 5 includes a shift fork 51, a blocking plate 52 and a handle 53. The shift fork 51 passes through the slide groove 43 and is arranged on the inner side of the cabinet door 4. The blocking plate 52 is arranged on the outer side of the cabinet door 4. The blocking plate 52 can block the slide groove 43. The blocking plate 52 passes through the fixed plate 41. The handle 53 is arranged on the outer side of the cabinet door 4. The shift fork 51 can be clamped in the ventilation joint 31.

[0063] In this embodiment, the pressing mechanism 5 can be pressed down to pull the force storage spring 42, and when the pressing mechanism 5 is released, the force storage spring 42 can drive the pressing mechanism 5 to rise up;

[0064] When the cabinet door 4 is closed, the handle 53 is pulled to press down the crimping mechanism 5, so that the fork 51 can drive the ventilation connector 31 to descend, and then the ventilation connector 31 can be connected to the bottle mouth at the top of the gas storage bottle 6. After releasing the handle 53, the force storage spring 42 can drive the crimping mechanism 5 to rise, and the fork 51 can drive the ventilation connector 31 to rise, and then the ventilation connector 31 can be disconnected from the bottle mouth at the top of the gas storage bottle 6, thereby realizing the connection procedure outside the cabinet door 4 and effectively protecting the operator.

[0065] like Figure 1 - Figure 2 As shown, the gas collecting hood 7 is connected to the cabinet 1.

[0066] In the present embodiment, the gas collecting hood 7 is connected to the cabinet 1, and the gas collecting hood 7 is connected to the gas collecting device. During the process of inflating the gas cylinder 6, a small amount of hydrogen leakage can be discharged through the gas collecting hood 7, which effectively enhances the safety of inflating the gas cylinder 6 and prevents the accumulation of hydrogen in the cabinet 1, thereby avoiding the occurrence of danger. Even if the gas cylinder 6 explodes or other dangerous faults occur, the explosion impact will first diffuse toward the direction of the gas collecting hood 7, reducing the impact of the cabinet door 4, and effectively protecting the operator.

[0067] Working principle:

[0068] When the gas cylinder 6 needs to be replaced, the cabinet door 4 is opened and the cylinder frame 2 is pulled out. At this time, the gas exchange mechanism 3 slides in the opposite direction. When the cylinder frame 2 is pulled out to load the gas cylinder 6, the gas cylinder 6 will not collide with the gas exchange mechanism 3, thereby avoiding the occurrence of danger;

[0069] Then, the gas cylinder 6 is placed in the cylinder frame 2, and the support plate 22 can support the gas cylinder 6. The setting of the buffer spring 222 can reduce the impact on the gas cylinder 6 and enhance the safety of the gas cylinder 6. After supporting the gas cylinder 6, the support plate 22 will drop, and the first rack 221 can drop together with the support plate 22.

[0070] When the support plate 22 descends, the first rack 221 can drive the gear ring 231 to rotate forwardly, and the gear ring 231 can drive the two clamps 21 to move closer to each other, so that the two clamps 21 clamp the gas cylinder 6. At the same time, it can ensure that when the clamp 21 clamps the gas cylinder 6, the gas cylinder 6 is in the middle of the cylinder frame 2, that is, the bottle mouth of the top of the gas cylinder 6 is in the middle;

[0071] Then push the bottle frame 2 back into the cabinet 1, and the ventilation mechanism 3 slides horizontally in the direction close to the bottle frame 2. When the bottle frame 2 finally returns to its original position, the ventilation mechanism 3 is just back to the top of the bottle frame 2, that is, the ventilation joint 31 is just above the top of the gas bottle 6, and the cabinet door 4 can be closed at this time;

[0072] After the cabinet door 4 is closed, the shift fork 51 is located above the ventilation connector 31. Pulling the handle 53 to press down the crimping mechanism 5 can make the shift fork 51 drive the ventilation connector 31 to descend, and then make the ventilation connector 31 connect with the bottle mouth at the top of the gas storage bottle 6. At this time, the charging device can be turned on to inflate the gas storage bottle 6.

[0073] After the inflation is completed, the handle 53 can be released, and the force storage spring 42 can drive the crimping mechanism 5 to rise, so that the fork 51 can drive the venting connector 31 to rise, and then the venting connector 31 is disconnected from the bottle mouth at the top of the gas storage bottle 6, so that the connection procedure can be operated outside the cabinet door 4, which effectively protects the operator;

[0074] When it is necessary to take out the gas cylinder 6 after the gas is filled, the cabinet door 4 is opened to pull out the cylinder frame 2, and then the gas cylinder 6 is taken out from the cylinder frame 2. The support plate 22 will rise, so that the first rack 221 rises together with the support plate 22, and the first rack 221 can drive the gear ring 231 to reverse, and the gear ring 231 reverses to drive the two clamps 21 to move away from each other, so that the two clamps 21 release the clamping of the gas cylinder 6, and the gas cylinder 6 can be easily taken out;

[0075] Whether inflating or preserving the gas cylinder 6, the gas in the cabinet 1 can be discharged through the gas collecting hood 7, ensuring that hydrogen leakage can be quickly discharged from the cabinet 1, effectively enhancing the safety of inflating the gas cylinder 6, preventing hydrogen from being enriched in the cabinet 1, and thus avoiding the occurrence of danger;

[0076] The bottle storage frame 2 may also be wrapped with an explosion-proof curtain to further enhance the protective effect and fully protect the life safety of the operating personnel.
