The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0030] In related technologies, nitrogen generators are typically all fixed and integrated into a single enclosure, facilitating transport and relocation, and saving on wiring. However, since nitrogen generators usually include an air compressor, nitrogen generator, and control circuitry, the air compressor generates vibrations during operation, which can easily affect other structures, such as causing loosening or damage to connections in the nitrogen generator or control circuitry. Simultaneously, while the nitrogen generator needs to maintain good airtightness, the air compressor and control circuitry can be exposed to the outside environment, leading to complex maintenance procedures and potentially compromising the nitrogen generator's airtightness. Furthermore, nitrogen generators include filters connected to the nitrogen generator; the filter elements are consumable parts requiring frequent replacement and maintenance, increasing the risk of interference with other structures.

[0031] Based on this, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6This application provides a nitrogen generator according to one embodiment, which facilitates later maintenance and reduces the risk of damage to other components during maintenance, thereby improving safety performance. Specifically, the nitrogen generator includes a support 100 and multiple functional modules 200 mounted on the support 100. The multiple functional modules 200 include at least a shock-absorbing module 210, a fireproof module 220, and a sealing module 230. The shock-absorbing module 210 is used to house the vibrating component 211, the fireproof module 220 is used to house the electrical component 221, and the sealing module 230 is used to house the nitrogen generating component 231.

[0032] The component 211 that generates vibration refers to a component that vibrates during operation in order to achieve its main function, such as an air compressor 2111.

[0033] Electrical component 221 refers to circuit components used for control via electrical or radio signals. Examples of electrical components 221 include circuit breakers 2211, power converters 2212, and controllers 2213. Electrical component 221 is used to control the normal operation of the nitrogen generator. If electrical component 221 experiences a short circuit or other fault, it may generate electrical sparks. If flammable materials are present around electrical component 221, it could easily lead to a fire or other accidents.

[0034] Nitrogen generating component 231 refers to the structure used for nitrogen generation, such as nitrogen generator 2313, filter 2311, etc. Nitrogen generating component 231 needs to maintain airtightness.

[0035] In other words, in this embodiment, the vibration-generating component 211, the electrical component 221 which is prone to sparks and fires, and the nitrogen generator component 231 which needs to maintain airtightness can be divided into independent modules, and these three components can be independently isolated and assembled with their respective supports 100 to avoid interference between the components. For example, the vibration-generating component 211 can be located at a lower position on the support 100, while the electrical component 221 and the nitrogen generator component 231 can be located at a higher position on the support 100. This arrangement can reduce the impact of the vibration-generating component 211 on the electrical component 221 and the nitrogen generator component 231. Furthermore, because each module is independent of the others, when repairing a component in one module, it will not directly interfere with the components in other modules. For example, when the electrical component 221 malfunctions and needs repair, it can avoid affecting the airtightness of the nitrogen generator component 231; or, when the vibration-generating component 211 needs repair, it can reduce interference with the electrical component 221 and the nitrogen generator component 231. In this way, the risk of damage to other components during maintenance can be reduced, and safety performance can be improved.

[0036] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, in actual use, the vibration damping module 210 includes a vibration damping housing 212, and the vibrating component 211 is placed inside the vibration damping housing 212. The vibration damping housing 212 isolates the vibrating component 211 from the fireproof module 220 and the sealing module 230. Meanwhile, the fireproof module 220 includes a fireproof housing 222, and the electrical component 221 is placed inside the fireproof housing 222. The sealing module 230 includes a sealing housing 233, and the nitrogen generator 231 is placed inside the sealing housing 233. It can be understood that the vibration damping housing 212, the fireproof housing 222, and the sealing housing 233 ensure that the vibrating component 211, the electrical component 221, and the nitrogen generator 231 are completely spatially isolated from each other and do not interfere with each other. When one of them malfunctions, only the corresponding housing needs to be opened, without affecting the other components.

[0037] Furthermore, the vibration damping housing 212 is provided with a first inspection port, and the vibration damping module 210 also includes a first inspection window 213, which is located at the first inspection port. When maintenance is required, the first inspection window 213 can be opened to maintain the vibrating components 211 inside; after maintenance is completed, the first inspection window 213 is closed to provide protection. Similarly, the fireproof housing 222 is provided with a second inspection port, and the fireproof module 220 also includes a second inspection window 223, which is located at the second inspection port. The sealed housing 233 is provided with a third inspection port, and the sealing module 230 also includes a third inspection window 234, which is located at the third inspection port. The provision of the second inspection window 223 and the third inspection window 234 is for the convenience of maintaining the electrical components 221 and the nitrogen generating components 231. Among them, the edges of the third inspection window 234 and the third inspection port are pressed with sealing rings to ensure the sealing performance of the third inspection window 234 when it is closed, thereby ensuring the overall airtightness of the sealed box 233.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the aforementioned first inspection window 213, second inspection window 223, and third inspection window 234 are all arranged on the same side. That is, the inspection positions of the shock-absorbing module 210, fireproof module 220, and sealing module 230 can all be located on the same side, facilitating maintenance and eliminating the need to adjust the orientation of the nitrogen generator during maintenance. Of course, the three inspection windows can also be arranged on different sides to further reduce maintenance interference.

[0039] Please see Figure 1 , Figure 2 and Figure 7In some embodiments, the bracket 100 includes a first assembly layer 110 and other assembly layers 120. The first assembly layer 110 is located below the other assembly layers 120 in the vertical direction. The shock-absorbing module 210 is located on the first assembly layer 110, and the fireproof module 220 and the sealing module 230 are both located on the other assembly layers 120. That is, the shock-absorbing module 210 is located below the fireproof module 220 and the sealing module 230. It can be understood that since the vibrating component 211 is placed inside the shock-absorbing housing 212 of the shock-absorbing module 210, this arrangement allows the center of gravity of the shock-absorbing module 210 to be set lower, which not only improves installation stability but also reduces the impact of vibration on the fireproof module 220 and the sealing module 230, thereby extending the overall service life of the nitrogen generator.

[0040] When the bracket 100 is placed on the ground, the distance between the first assembly layer 110 and the ground is relatively small. In some specific embodiments, the bottom of the first assembly layer 110 is also supported on the ground, resulting in better stability.

[0041] In some embodiments, other assembly layers 120 include at least a second assembly layer 1201, and the bracket 100 further includes a partition 130. The partition 130 is disposed on the second assembly layer 1201 and divides the second assembly layer 1201 into a first side and a second side, with the fireproof module 220 and the sealing module 230 respectively disposed on the first side and the second side. For example, the first side is located on the left side of the second side, the fireproof module 220 is disposed on the first side, and the sealing module 230 is disposed on the second side. Conversely, the first side can also be disposed on the front or rear side of the second side; this is only an example. This arrangement can further separate the fireproof module 220 and the sealing module 230; and both the fireproof housing 222 and the sealing housing 233 can be connected to the partition 130, improving assembly reliability.

[0042] Please see Figure 7 In some specific embodiments, the support 100 includes columns 1001 and crossbeams 1002. The columns 1001 have four crossbeams spaced apart circumferentially along the support 100. At least two crossbeams 1002, spaced apart along the length of the column 1001 (i.e., the vertical direction, i.e., the Z-axis direction), connect adjacent columns 1001 circumferentially, thus forming a four-sided frame-like support 100. The crossbeams 1002 include a first crossbeam 1002a extending along the X-axis and a second crossbeam 1002b extending along the Y-axis. At least two second crossbeams 1002b, spaced apart along the X-axis, connect two first crossbeams 1002a, and at least two first crossbeams 1002a, spaced apart along the Y-axis, connect two second crossbeams 1002b. A support surface composed of multiple crossbeams 1002 located in the same plane serves as an assembly layer.

[0043] For example, the projection of the bracket 100 along the vertical direction Z is rectangular. Corresponding to the first assembly layer 110, four second crossbeams 1002b spaced apart along the X-axis are connected between the two first crossbeams 1002a. Further, for the second assembly layer 1201, two first crossbeams 1002 spaced apart along the Y-axis are connected between the two second crossbeams 1002b, one of the first crossbeams 1002a is connected to one end of the two second crossbeams 1002b, and the other first crossbeam 1002a is connected to the middle of the two second crossbeams 1002b, causing a notch to be formed at the other end of the two second crossbeams 1002b, facilitating the assembly of pipes or lines between the shock absorption module 210 and the fireproof module 220 and the sealing module 230. The aforementioned partition 130 may include two columns 1001 and a crossbeam 1002 connected between the two columns 1001, and the partition 130 is arranged in a U-shape.

[0044] Please continue reading. Figure 1 , Figure 2 and Figure 7 In some embodiments, the other assembly layers 120 also include a third assembly layer 1202. The third assembly layer 1202, the second assembly layer 1201, and the first assembly layer 110 are arranged sequentially from top to bottom along the vertical direction Z. The bottom of the partition 130 is connected to the second assembly layer 1201, and the top of the partition 130 is connected to the third assembly layer 1202. The shock-absorbing module 210 is supported and connected to the first assembly layer 110, and the shock-absorbing housing 212 is screwed to the column 1001 and the corresponding crossbeam 1002 of the first assembly layer 110. There is a gap between the shock-absorbing module 210 and the second assembly layer 1201 to facilitate the accommodation of the aforementioned pipes or lines. The bottom of the fireproof module 220 and the bottom of the sealing module 230 are supported and connected to the second assembly layer 1201, and their tops can also be connected to the third assembly layer 1202 to improve the connection reliability. Both the fireproof enclosure 222 and the sealed enclosure 233 are fastened to the column 1001 and the corresponding crossbeam 1002 by screws.

[0045] The third assembly layer 1202 can also connect to other structures, or it can simply serve as a structural reinforcement during assembly.

[0046] Please see Figure 1 and Figure 3In some embodiments, the vibration damping module 210 includes a vibration damping pad 215, which is disposed on the surface of the vibrating component 211 that contacts the vibration damping module 210. By using the vibration damping pad 215, the vibration generated by the vibrating component 211 can be damped and buffered, reducing the vibration transmitted to the support 100, thereby reducing the vibration impact on the fireproof module 220 and the sealing module 230, and improving the reliability of the entire nitrogen generator. For example, the vibration damping pad 215 is disposed between the vibrating component 211 and the vibration damping housing 212.

[0047] Please see Figure 1 , Figure 3 and Figure 4 In some embodiments, the vibration-generating component 211 includes at least an air compressor 2111, and a vibration-damping pad 215 is disposed between the bottom of the air compressor 2111 and the bottom wall of the vibration-damping module 210, that is, the vibration-damping pad 215 is disposed between the bottom of the air compressor 2111 and the bottom wall of the vibration-damping housing 212. This reduces the vibration transmitted from the air compressor 2111 to the support 100. The air compressor 2111 is connected to the nitrogen generator 231 to provide compressed air to the nitrogen generator 231. The air compressor 2111 is equipped with a control module 2111a, which is electrically connected to the electrical component 221 to facilitate the energy supply and operation control of the air compressor 2111.

[0048] Furthermore, the vibration-generating component 211 also includes a radiator 2112, which is spaced apart from the air compressor 2111 and is used to dissipate heat from the air compressor 2111. Since the air compressor 2111 generates a large amount of heat during operation, the radiator 2112 helps cool the air compressor 2111, reducing the overheating effects on its internal components. The radiator 2112 also vibrates during operation, so a vibration-damping pad 215 is provided between the radiator 2112 and the vibration-damping housing 212. The radiator 2112 and the air compressor 2111 can share a single vibration-damping pad 215, or they can each have independent vibration-damping pads 215. The vibration-damping pad 215 can be a single sheet adapted to the wall of the vibration-damping housing 212, or it can be in the form of a block or strip, in which case multiple vibration-damping pads 215 can be spaced apart. This is only an example.

[0049] In actual use, the shock absorber housing 212 is equipped with a heat dissipation vent, and the shock absorber module 210 also includes a heat dissipation window 214, which is located at the heat dissipation vent. This arrangement facilitates the discharge of high-temperature gas inside the shock absorber housing 212, improving the heat dissipation effect. The heat dissipation vent is spaced apart from the first inspection port.

[0050] The heat sink 2112 can be air-cooled, such as by a fan; or it can be liquid-cooled. It only needs to meet the heat dissipation requirements.

[0051] Please see Figure 1 and Figure 3 In some embodiments, the nitrogen generating component 231 includes at least a filter 2311, a dryer 2312, a nitrogen generator 2313, and a nitrogen storage tank 2314 connected in series. The outlet of the air compressor 2111 is connected to the inlet of the filter 2311, and the outlet of the nitrogen storage tank 2314 is connected to a concentration sensor 2315 and a flow sensor 2316. Specifically, the air compressor 2111 draws in ambient air and compresses it to the pressure required for nitrogen generation, then delivers it to the filter 2311. After being filtered and purified by the filter 2311, the air is then delivered to the dryer 2312 for drying. The dried gas is then delivered to the nitrogen generator 2313 for processing to separate nitrogen gas, which is then delivered to the nitrogen storage tank 2314 for storage. During this process, the filter 2311, dryer 2312, nitrogen generator 2313, and nitrogen storage tank 2314 all require good airtightness to prevent leakage or contamination by external gases that could affect the nitrogen concentration. The air compressor 2111 not only needs to be connected to the external environment, but also generates vibration during operation. Therefore, the air compressor 2111 and the aforementioned nitrogen generating component 231 are separated to improve overall safety performance.

[0052] Both the concentration sensor 2315 and the flow sensor 2316 are electrically connected to the aforementioned electrical component 221, and the nitrogen generator 231 is also electrically connected to the electrical component 221. Nitrogen stored in the nitrogen storage tank 2314 can be transported to the target location requiring nitrogen via pipelines. During transport, the concentration sensor 2315 can monitor the nitrogen concentration in real time; a higher concentration indicates higher nitrogen purity. If the concentration falls below a preset threshold, the electrical component 221 can alert personnel to take timely action based on the detection signal from the concentration sensor 2315. For example, it may indicate a malfunction in the filter 2311 or the nitrogen generator 2313, facilitating timely repair.

[0053] Meanwhile, the flow sensor 2316 is used to monitor the output flow rate of nitrogen in real time, thereby determining whether the performance of the air compressor 2111 or the nitrogen generator 231 is normal. If the flow rate is much lower than the preset threshold, it may be due to insufficient air supply from the air compressor 2111, blockage of the filter 2311, or decreased efficiency of the nitrogen generator 2313, allowing staff to respond promptly based on the detection signal from the flow sensor 2316.

[0054] The nitrogen generator 2313 can utilize either pressure swing adsorption (PSA) technology or membrane separation technology, as long as it can separate nitrogen from the air.

[0055] Please continue reading. Figure 1 and Figure 3 In some embodiments, a gas supply pipe 240 connects the sealing module 230 and the fireproof module 220. The gas supply pipe 240 is connected to a nitrogen generator 231 for injecting nitrogen into the fireproof module 220. Because the electrical components 221 inside the fireproof module 220 may generate electrical sparks due to air breakdown, posing a fire risk, nitrogen is introduced into the fireproof enclosure 222 via the gas supply pipe 240 to create a low-oxygen environment for the electrical components 221, thereby improving the fireproof effect.

[0056] In practical use, a control valve 241 is installed on the gas supply pipe 240 to control the opening and closing of the gas supply pipe 240. The control valve 241 can be a solenoid valve, electrically connected to the electrical component 221 for easy control. When the control valve 241 is open (opening degree greater than 0), the gas supply pipe 240 is connected, allowing nitrogen to flow into the fireproof enclosure 222. The flow rate can be adjusted according to the opening degree of the control valve 241. When the control valve 241 is closed (opening degree 0), the gas supply pipe 240 is interrupted, preventing nitrogen from flowing into the fireproof enclosure 222. For example, when the electrical component 221 needs maintenance, the control valve 241 is closed; after maintenance is completed, the control valve 241 is opened.

[0057] Furthermore, the nitrogen storage tank 2314 is also connected to an outlet pipe 232, which is used to connect to the nitrogen-filling device, thereby transporting the nitrogen gas in the nitrogen storage tank 2314 to the nitrogen-filling device. The outlet pipe 232 and the aforementioned gas delivery pipe 240 are both connected in parallel to the outlet end of the nitrogen storage tank 2314. In some specific embodiments, the sealed housing 233 is provided with a first through hole for the outlet pipe 232 to pass through and a second through hole for the gas delivery pipe 240 to pass through. Sealing rings or sealing fillers are provided between the outlet pipe 232 and the wall of the first through hole, and between the gas delivery pipe 240 and the wall of the second through hole.

[0058] In some specific embodiments, the inlet end of the gas delivery pipe 240 is connected between the concentration sensor 2315 and the flow sensor 2316, and the concentration sensor 2315 is located upstream of the flow sensor 2316 along the nitrogen delivery direction.

[0059] In actual use, the sealing module 230 also includes an exhaust pipe 235, which includes a manifold and multiple branch pipes connected to the manifold. The multiple branch pipes are respectively connected to the filter 2311, the dryer 2312, the nitrogen generator 2313 and the nitrogen storage tank 2314. The manifold extends out of the sealing housing 233 to discharge the exhaust gas during the nitrogen generation process.

[0060] Among them, the aforementioned exhaust pipe 235, gas transmission pipe 240, and the pipes connected between the air compressor 2111, filter 2311, dryer 2312, nitrogen generator 2313, nitrogen storage tank 2314 and exhaust pipe 232 for gas transmission are all collectively referred to as gas pipes.

[0061] Please continue reading. Figure 1 and Figure 3 In some embodiments, electrical component 221 includes power converter 2212, circuit breaker 2211, relay 2215, AC contactor 2214, and controller 2213, which are connected in series. AC contactor 2214 is electrically connected to control module 2111a of air compressor 2111 via relay 2215. AC contactor 2214 and relay 2215, and relay 2215 and control module 2111a are connected via high-voltage wiring harnesses. Circuit breaker 2211 and power converter 2212, and circuit breaker 2211 and AC contactor 2214 are also connected via high-voltage wiring harnesses. Meanwhile, the controller 2213 is connected to the nitrogen generator 231 via a low-voltage wiring harness, and the power converter 2212 is also connected to the controller 2213, and the controller 2213 is also connected to the AC contactor 2214 via a low-voltage wiring harness.

[0062] In practical use, electrical component 221 has a low-voltage wiring harness connected to controller 2213 and a high-voltage wiring harness connected to relay 2215. Nitrogen generator component 231 has a main bus harness and multiple branches connected to the main bus harness. The multiple branches are respectively connected to flow sensor 2316, concentration sensor 2315, dryer 2312, nitrogen generator 2313, and control valve 241. The main bus harness is connected to the low-voltage wiring harness. Vibration-generating component 211 has a connecting wiring harness. The control module 2111a and the heat dissipation controller corresponding to heat sink 2112 are connected in series through the connecting wiring harness. The connecting wiring harness is connected to the high-voltage wiring harness.

[0063] The aforementioned high-voltage wiring harness, low-voltage wiring harness, main wiring harness and branch wiring harness of nitrogen generator 231, and connecting wiring harness corresponding to vibration-generating component 211 are collectively referred to as wires.

[0064] Please continue reading. Figure 1 and Figure 3In some embodiments, the wiring for electrical signal transmission between the shock-absorbing module 210 and the fireproof module 220, and between the sealing module 230 and the fireproof module 220, are all connected using quick-connect fittings. This arrangement facilitates quick assembly and disassembly, improving efficiency. Specifically, the nitrogen generator also includes a first main line 252 and a second main line 253. The first main line 252 connects the connecting harness and the high-voltage harness, and the second main line 253 connects the main harness and the low-voltage harness. Both the first main line 252 and the second main line 253 use quick-connect fittings.

[0065] In some embodiments, the gas supply line between the shock-absorbing module 210 and the sealing module 230 is connected by a quick-connect pipe. Specifically, the air compressor 2111's outlet end and the connector's inlet end each have their own gas pipes. The nitrogen generator also includes a vent pipe 251, which connects the two gas pipes. The vent pipe 251 uses a quick-connect pipe to mate with the gas pipes for easy assembly and disassembly. The quick-connect pipe is a quick-connect fitting.

[0066] like Figure 1 As shown, in some embodiments, at least one of the shock-absorbing module 210, fireproof module 220, and sealing module 230 is removably mounted on the bracket 100. This arrangement not only facilitates the assembly of each module relative to the bracket 100 but also facilitates the maintenance of each module. For example, the bracket 100 is provided with a sliding groove, and the corresponding housing of each module is provided with rollers that roll within the sliding groove for easy removal. Of course, it is also possible that only the shock-absorbing module 210 is removably mounted on the bracket 100 via its shock-absorbing housing, or that the shock-absorbing module 210 and the sealing module 230 are each removably mounted on the bracket 100 via their respective housings, or that only the fireproof module 220 is removably mounted on the bracket 100 via its fireproof housing 222. This is merely an example.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
