Description

Technical Field

[0001] The present invention relates to the field of new energy technology, and in particular to a sequence control panel for a hydrogen refueling station. Background Art

[0002] As one of the world's most promising clean energy sources, hydrogen is considered by many countries to be the "ultimate new energy vehicle solution." Hydrogen refueling stations are to fuel cell vehicles what gas stations are to traditional gasoline vehicles and charging stations are to pure electric vehicles. They are an essential cornerstone supporting the development of the fuel cell vehicle industry.

[0003] The global hydrogen energy and fuel cell market is still in the market introduction stage. The hydrogen refueling stations on the market are currently high-pressure gas hydrogen storage and refueling stations. The hydrogen reserves of high-pressure gas hydrogen storage and refueling stations are transported to high-pressure gas hydrogen storage and refueling stations by high-pressure hydrogen transport vehicles. The high-pressure hydrogen in the high-pressure hydrogen transport vehicle is then pressurized by a hydrogen compressor and transported to the hydrogen storage container cache in the high-pressure gas hydrogen storage and refueling station. During refueling, the high-pressure hydrogen in the hydrogen storage container is regulated by a heat exchanger and then transported to the hydrogen refueling machine for refueling. The refueling capacity supply scale of high-pressure gas hydrogen storage and refueling stations is mostly 100-500kg / d, and the maximum can reach 1000kg / d. However, even with a maximum daily refueling capacity of 1000kg / d, it can only refuel a maximum of 25 buses or 100 passenger cars per day.

[0004] Liquid hydrogen has a volume density of 70.8 kg / m³ and a volumetric energy density of 8.5 MJ / L, 6.5 times that of gaseous hydrogen at a transport pressure of 15 MPa. Compared to gaseous hydrogen, liquid hydrogen offers significant advantages in terms of loading capacity, loading and unloading time, storage pressure, and footprint. Gaseous hydrogen is primarily transported by tube trailers, each capable of carrying 250-460 kg of hydrogen per vehicle, making it suitable for small-scale, short-distance transportation. Liquid hydrogen is primarily transported by tanker trucks, each capable of carrying approximately 4,000 kg of hydrogen per vehicle, making it suitable for large-scale, long-distance transportation. Deep-cooling hydrogen to 21K to liquefy it, and then transporting it to liquid hydrogen storage and refueling stations via tanker trucks or pipelines, will significantly improve transportation efficiency and reduce hydrogen costs. In addition to tanker trucks and pipelines, liquid hydrogen can also be transported over long distances and across continents by rail and ship, enabling the future convenient trading of liquid hydrogen as an energy source in the global market.

[0005] Although there are hydrogen refueling stations on the market, and they are also equipped with sequential control panels, there are currently no protective devices to protect the hydrogen refueling stations and sequential control panels, which poses a major safety hazard.

Then, the detection device can send a control signal to the lifting device, so that the lifting device can drive the sequential control panel body to rise to a safe position, ensuring that the sequential control panel body will not be affected by the flood, thereby improving safety.

[0031] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0032] like Figure 1-2 As shown, a sequential control panel for a hydrogen refueling station in one embodiment of the present invention includes a sequential control panel body 1, a frame 2, a detection device 3 and a lifting device 4, the lifting device 4 is installed on the frame 2, the sequential control panel body 1 and the detection device 3 are both installed on the lifting device 4, the detection device 3 is communicatively connected to the lifting device 4, and the detection device 3 is used to measure the height of the bottom water surface of the sequential control panel body 1 from the bottom of the sequential control panel body 1.

[0033] The above-mentioned sequential control panel for hydrogen refueling station is provided with a frame 2, a detection device 3 and a lifting device 4. The lifting device 4 is installed on the frame 2, and the sequential control panel body 1 and the detection device 3 are both installed on the lifting device 4. In this way, the lifting device 4 can drive the sequential control panel body 1 to perform lifting movements. The detection device 3 is communicated with the lifting device 4 through the detection device 3. The detection device 3 is used to measure the height of the water surface at the bottom of the sequential control panel body 1 from the bottom of the sequential control panel body 1, so that when a flood occurs, the detection device 3 can measure the height of the water surface at the bottom of the sequential control panel body 1 from the bottom of the sequential control panel body 1, and then the detection device 3 can send a control signal to the lifting device 4, so that the lifting device 4 can drive the sequential control panel body 1 to rise to a safe position, ensuring that the sequential control panel body 1 will not be affected by the flood, thereby improving safety.

[0034] like Figure 5 As shown, in one embodiment, the lifting device 4 includes a driving device 43, a sliding plate 44 and a guide rod 46. The guide rod 46 is connected to the frame 2, the sliding plate 44 is slidably connected to the guide rod 46, and the driving device 43 is drivingly connected to the sliding plate 44. In this way, the guide rod 46 can guide the sliding plate 44. At the same time, the driving device 43 is driven and connected to the sliding plate 44 through the driving device 43, so that the driving device 43 can drive the sliding plate 44, so that the sliding plate 44 can slide on the guide rod 46.

[0035] like Figure 5 As shown, in one embodiment, the lifting device 4 also includes a placement plate 41 and a sliding plate 44 connected to the placement plate 41. The placement plate 41 is used to place the sequential control disk body 1. In this way, the sequential control disk body 1 can be placed on the placement plate 41. When the driving device 43 drives the sliding plate 44, the sliding plate 44 is connected to the placement plate 41, so that the driving device 43 can drive the sequential control disk body 1 to perform lifting and lowering movements.

[0036] like Figure 3 as well as Figure 5 As shown, in one embodiment, the lifting device 4 also includes a guide plate 42, the frame 2 includes a mounting rod 21, the guide plate 42 is slidably connected to the mounting rod 21, the mounting rod 21 is provided with a guide groove 211, the guide plate 42 is provided with a guide curved block 421, the guide groove 211 is slidably connected to the guide curved block 421, so that the guide groove 211 is slidably connected to the guide curved block 421, thereby realizing the sliding connection between the guide plate 42 and the mounting rod 21, that is, the guide curved block 421 on the mounting rod 21 can guide the movement of the guide plate 42, thereby realizing that the lifting device 4 is more stable during the lifting movement.

[0037] like Figure 3 as well as Figure 4 As shown, in one embodiment, the frame 2 also includes a locking device 22, which is connected to the mounting rod 21, and the lifting device 4 includes a locking rod 47, which is locked and connected to the locking device 22. In this way, the locking rod 47 is locked and connected to the locking device 22, so that the locking device 22 can perform a locking process on the locking rod 47.

[0038] like Figure 3 as well as Figure 4 As shown, in one embodiment, the locking rod 47 is provided with a locking guide groove 471, and the locking guide groove 471 is slidably connected to the locking device 22. In this way, the locking guide groove 471 is slidably connected to the locking device 22, so that the locking device 22 can more conveniently perform the locking process on the locking rod 47.

[0039] like Figure 3 as well as Figure 4As shown, in one of the embodiments, preferably, the locking device 22 is a pressing elastic member, the number of the locking devices 22 is multiple, the locking devices 22 are evenly arranged on the mounting rod 21, and the locking guide groove 471 is an oblique groove. When the lifting device 4 rises, the locking guide groove 471 of the locking rod 47 first contacts the locking device 22. Since the locking guide groove 471 is an oblique groove, when the lifting device 4 continues to rise, the locking device 22 can be easily moved into the locking guide groove 471. At this time, the locking device 22 is squeezed by the locking guide groove 471, and the locking device 22 is pressed; the lifting device 4 continues to rise, and at this time the locking device 22 is located at the locking rod 47, and the locking device 22 is reset.

[0040] like Figure 5 As shown, in one embodiment, the lifting device 4 also includes a safety device 45 and a limit baffle 48. The safety device 45 is installed on the sliding plate 44, the limit baffle 48 is connected to the frame 2, and the limit baffle 48 is located above the safety device 45. The safety device 45 is driven by the driving device 43 to abut against the limit baffle 48. The limit baffle 48 is provided with an elastic component 481. The safety device 45 is driven by the driving device 43 to abut against the elastic component 481. In this way, it can be ensured that when the lifting device 4 rises to a certain height, the elastic component 481 on the limit baffle 48 can limit the rising movement of the lifting device 4, ensuring that the rising height of the lifting device 4 will not exceed the height of the guide rod 46, thereby ensuring the safety of the sequential control disk body 1.

[0041] like Figure 3 As shown, in one embodiment, the rack 2 further includes a positioning device 23, which is located below the rack 2. Preferably, there are multiple positioning devices 23. In this way, through multiple positioning devices 23, the rack 2 can be more firmly installed in the hydrogen refueling station, thereby increasing the safety of the sequential control panel body 1 when in use.

[0042] The working principle of the present invention is as follows: first, the sequential control disk body 1 is placed on the placement plate 41 of the lifting device 4, and then the detection device 3 is installed on the guide plate 42 of the lifting device 4. If a flood occurs, the detection device 3 can measure the height of the water surface at the bottom of the sequential control disk body 1 from the bottom of the sequential control disk body 1. When the water level continues to rise, the detection device 3 can send a control signal to the driving device 43 of the lifting device 4, and the driving device 43 starts to work, so that the driving device 43 drives the sliding plate 44, and then the sliding plate 44 can slide on the guide rod 46, so that the lifting device 4 can drive the sequential control disk body 1 to rise to a safe position; during the lifting process of the lifting device 4, the guide groove 211 is slidably connected with the guide curved block 421, so that the guide plate 42 and the mounting rod 21 can slide. The connection, that is, the guide curved block 421 on the mounting rod 21 can guide the movement of the guide plate 42, thereby realizing that the lifting device 4 is more stable when performing the lifting movement. At the same time, the locking rod 47 is connected to the locking device 22 to realize that the locking device 22 can perform the locking process on the locking rod 47. At this time, if the driving device 43 of the lifting device 4 rises to a certain height and the water affects the driving device 43, the locking rod 47 is connected to the locking device 22 and the guide groove 211 is slidingly connected to the guide curved block 421 to ensure that the lifting device 4 will not fall. That is, the locking device 22 is connected to the locking rod 47 to play a secondary safety insurance role, ensuring that the lifting device 4 will not fall when the driving device 43 fails due to being soaked in water.

[0043] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
