Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power generation container, in particular to a gas power generation container and a dustproof, waterproof and explosion-proof method thereof. BACKGROUND

[0002] The gas power generation container is a kind of power generation equipment which installs gas power generation unit, fuel supply system and electrical control system and other equipment in a container. This design makes the gas power generation unit have the characteristics of flexibility, convenience and strong mobility, and is suitable for temporary or emergency power supply demand in various scenes. The "three-proofing" (dustproof, waterproof and explosion-proof) of the electrical control system in the gas power generation container is the cornerstone of its safe operation: dustproofing avoids short circuit and overheating of electrical components; waterproofing maintains electrical insulation and avoids corrosion and electric leakage; explosion-proofing needs to avoid the accumulation of flammable gas in the container to prevent catastrophic accidents. At present, the three-proofing of the electrical system mainly depends on special protective cabinets or independent protective structures, and the overall volume of the equipment is large and the space utilization rate is low, which seriously restricts its miniaturization and vehicle-mounted mobility; at the same time, the existing high-protection-grade cabinets have problems such as complicated maintenance and high cost (such as the need to disassemble sealing bolts and replace sealing materials). SUMMARY

[0003] The present application provides a gas power generation container to solve the dustproof, waterproof and explosion-proof requirements of the gas power generation container and the problem of large and difficult-to-maintain three-proofing system equipment in related technologies.

[0004] In a first aspect, the present application provides a gas power generation container, comprising: a main container body, the main container body is divided into a unit compartment and an electrical compartment; a gas power generation unit is arranged in the unit compartment; an electrical control system is arranged in the electrical compartment, and the electrical control system is electrically connected with the gas power generation unit; a negative pressure ventilation system is connected with the unit compartment and is adapted to maintain a negative pressure environment in the unit compartment; and a positive pressure ventilation system is connected with the electrical compartment and is adapted to maintain a positive pressure environment in the electrical compartment.

[0005] The present application divides the main container body of the gas power generation container into independent unit compartments and electrical compartments, and matches the positive pressure ventilation system of the electrical compartment and the negative pressure ventilation system of the unit compartment: on the one hand, it reduces vibration, heat disturbance and gas crosstalk, and guarantees the stability and explosion-proof of the equipment; on the other hand, it can meet the "three-proofing" (dustproof, waterproof and explosion-proof) without traditional electrical protective cabinets, while improving the space utilization rate, adapting to more scenes, simplifying maintenance and reducing the overall cost.

[0006] In one optional embodiment, the gas-fired power generation container further includes a filtration chamber isolated from the generator compartment and the electrical compartment. The filtration chamber is equipped with filters arranged in multiple stages along the gas flow direction, with the filter diameter gradually decreasing across each stage. This multi-stage filtration arrangement provides the electrical compartment and generator compartment with clean air that meets their respective requirements, while simultaneously preventing backflow of pollutants and ensuring the efficiency of the ventilation system.

[0007] In one optional embodiment, the positive pressure ventilation system includes a centrifugal fan and a ventilation duct. The centrifugal fan is adapted to draw filtered air from the filtration chamber and pressurize it before delivering it to the ventilation duct. One end of the ventilation duct is connected to the centrifugal fan, and the other end is connected to the electrical compartment. The pressurization function of the centrifugal fan provides a stable positive pressure to the electrical compartment to resist the infiltration of external gases and ensure the protective effect. At the same time, the airflow can exchange heat with the heat-generating components inside the compartment, delaying component aging and improving the reliability of equipment operation.

[0008] In one optional embodiment, the negative pressure ventilation system includes an intake fan and an exhaust fan. The intake fan is adapted to draw filtered air from the filtration chamber and deliver it to the unit compartment, while the exhaust fan is adapted to exhaust air from the unit compartment. The intake fan and exhaust fan are adapted to provide a negative pressure environment for the unit compartment. The intake fan and exhaust fan operate together to maintain a negative pressure environment within the unit compartment, preventing gas diffusion and improving leakage discharge efficiency. Simultaneously, delivering filtered air reduces component wear, removes high temperatures, reduces condensation, lowers the risk of explosion and equipment failure, and extends service life.

[0009] In one optional embodiment, the filter chamber is stacked above the main housing. The filter chamber includes louvers and a top plate structure. The louvers are arranged circumferentially, with their lower sides attached to the main housing. The top plate structure is located above the louvers. The top of the main housing, the louvers, and the top plate structure together form a filter cavity, in which multiple stages of filter elements are disposed. The filter chamber, stacked above the main housing, does not occupy internal horizontal space, improving space utilization. Its circumferential louvers expand the air intake range and block impurities and rainwater. The filter cavity formed by the top of the main housing, the louvers, and the top plate structure protects the filter elements, extends their service life, and ensures a sufficient supply of clean air.

[0010] In one optional embodiment, the filter element includes a primary filter and a secondary filter. Along the gas flow direction, the intake fan is positioned after the primary filter and is adapted to draw air filtered by the primary filter within the filtration chamber. The centrifugal fan is positioned after the secondary filter and is adapted to draw air filtered by the secondary filter within the filtration chamber. This differentiated design, where the intake fan draws primary filtered air and the centrifugal fan draws secondary filtered air, precisely matches the different needs of the high cleanliness of the electrical compartment and the large airflow of the unit compartment, avoiding airflow competition and energy waste, and ensuring the efficient operation of the ventilation system.

[0011] In one optional embodiment, the intake fan and the exhaust fan are respectively located on opposite sides of the main housing along its length. This forms a through-type straight airflow channel, improving ventilation and heat dissipation efficiency, stabilizing the negative pressure in the unit compartment to reduce gas diffusion, and does not occupy the core space inside the compartment, facilitating independent maintenance.

[0012] In one optional embodiment, the electrical compartment is formed by welding multiple protective partitions together, or by welding protective partitions to the side walls of the main housing. Welds are formed at the welded joints of the protective partitions, and the ratio of (total volume of the electrical compartment / total volume of the main housing) to the weld penetration depth ranges from 0.76 mm⁻¹ to 4.55 mm⁻¹. This design provides sufficient leakage resistance to maintain stable positive pressure in the electrical compartment and ensure safety, while avoiding excessively thick protective partitions that would occupy too much space, thus meeting the requirements for equipment compactness and miniaturization.

[0013] In one optional embodiment, the first side wall of the main container is provided with an openable or closable opening. The electrical compartment is enclosed by a portion of the first side wall and the protective partition. The orthographic projection of the protective partition onto the first side wall at least partially coincides with the opening. Targeted inspection and replacement of electrical components can be performed outside the container, simplifying the process, shortening downtime, reducing maintenance difficulty, and ensuring the electrical compartment's airtightness and "three-proof" effect after inspection, thus improving operational flexibility and efficiency.

[0014] In one optional embodiment, the protective partition has a through-hole extending through its thickness, through which a cable passes. A sealing structure is provided within the through-hole, sealing the space between the protective partition and the cable. This ensures the integrity of the electrical compartment's seal and maintains a stable positive pressure environment, while reducing the erosion of cables by dust and moisture and frictional wear between the hole wall and the cable, thus lowering the risk of line failure.

[0015] In one optional embodiment, a gas detection unit is installed inside the electrical compartment. This gas detection unit is electrically connected to the electrical control system and is adapted to monitor the gas concentration within the electrical compartment and transmit the results to the electrical control system. The gas detection unit continuously monitors the concentration of hazardous gases within the electrical compartment. If leaked gas from the unit compartment seeps in and exceeds the limit, a signal can be transmitted to the electrical control system to promptly trigger alarms or emergency shutdown measures.

[0016] In one optional embodiment, a pressure detection unit is installed inside the electrical compartment. This unit is electrically connected to the electrical control system and is adapted to detect the pressure inside the electrical compartment and transmit the result to the electrical control system. The pressure detection unit provides real-time feedback of the pressure data inside the electrical compartment, ensuring it remains within a set positive pressure range and promptly detecting pressure anomalies caused by weld leaks, seal failures, or centrifugal fan malfunctions.

[0017] In one optional embodiment, the electrical compartment is provided as a plurality of separate compartments, and the plurality of electrical compartments are connected by inter-compartment ventilation ducts. The plurality of electrical compartments separated according to the function of electrical components can reduce component interference, delay the spread of local contamination and thus reduce overall risk, while the inter-compartment ventilation ducts can balance the air pressure in each compartment, ensuring that all zones maintain a set positive pressure.

[0018] Secondly, this application also provides a method for dustproofing, waterproofing, and explosion-proofing of a gas-fired power generation container, including the following steps: S1. Check whether there are any structural or sealing abnormalities in the gas-fired power generation container. If there are no abnormalities, proceed to S2. If there are abnormalities, stop the subsequent steps, record the abnormality, take corresponding corrective measures, and then proceed to S2. S2. Activate the positive pressure ventilation system to purge the electrical compartment; S3. Start the negative pressure ventilation system to exhaust the unit compartment; S4. After the first preset time, the electrical control system checks whether the start-up requirements are met through its configured gas detection unit. If the start-up requirements are met, the gas generator set in the unit compartment is started. S5. After startup, the positive pressure ventilation system continues to work to maintain a positive pressure state in the electrical compartment; S6. After shutdown, shut down the positive pressure ventilation system when the temperature inside the main chamber drops to the preset temperature.

[0019] The entire workflow enables tri-proof protection for gas-fired power generation containers, adapting to the safety operation requirements under complex working conditions such as the field, and ensuring the safety and stability of gas-fired power generation container operation.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The electrical control system 3, as the control center of the gas-fired power generation container, contains a large number of precision electrical components. Its "three-proof" (dustproof, waterproof, and explosion-proof) performance directly determines whether the equipment can operate safely and stably, and is the core foundation for ensuring the continuous and reliable operation of the gas-fired power generation system. In related technologies, the realization of the "three-proof" function often relies on dedicated protective cabinets or separately installed protective structures outside the container. This not only occupies a large space and has low space utilization, resulting in a large overall container volume after the equipment is assembled, restricting the miniaturization of field equipment and its adaptability to vehicle-mounted mobility, but also requires disassembling the panel and sealing bolts for maintenance, making operation cumbersome and maintenance inconvenient. Therefore, there is an urgent need for a gas-fired power generation container that can stably realize the "three-proof" function of the electrical control system 3 without reducing the degree of equipment integration and while ensuring ease of maintenance.

[0024] The following is combined Figures 1 to 3 This describes an embodiment of the present application.

[0025] According to an embodiment of this application, in one aspect, a gas-fired power generation container is provided, including a main body 1, which is divided into a generator compartment 1A and an electrical compartment 1B; a gas generator set 2 is disposed in the generator compartment 1A; an electrical control system 3 is disposed in the electrical compartment 1B and is electrically connected to the gas generator set 2; a negative pressure ventilation system is connected to the generator compartment 1A and is adapted to maintain a negative pressure environment in the generator compartment 1A; and a positive pressure ventilation system is connected to the electrical compartment 1B and is adapted to maintain a positive pressure environment in the electrical compartment 1B.

[0026] The gas-fired power generation container of this embodiment, through a reasonable partitioning design of the main container body 1, divides the generator compartment 1A and the electrical compartment 1B into independent functional spaces. On the one hand, this significantly reduces the interference of vibration and heat generated during the operation of the gas generator set 2 on the electrical control system 3, ensuring control accuracy and equipment stability. On the other hand, it significantly reduces gas crosstalk between the two compartments, laying the foundation for maintaining different gas pressure environments for each. Specifically, the electrical compartment 1B maintains a positive pressure state through a positive pressure ventilation system, which can effectively isolate the intrusion of flammable gases that may leak from the generator compartment 1A, and significantly reduce the entry of external dust, moisture and other pollutants, significantly reducing the risk of short circuits, corrosion or insulation failure of precision components in the electrical control system 3. The generator compartment 1A, on the other hand, maintains a negative pressure environment through a negative pressure ventilation system, which can quickly and efficiently discharge gas that may leak during the operation of the gas generator set 2, significantly reducing the probability of flammable gas accumulation and further preventing explosions. This application achieves stable dustproof, waterproof, and explosion-proof protection by coordinating the design of the container partition and ventilation system, without relying on traditional electrical protective cabinets. This not only improves the space utilization of the main container 1, but also facilitates the miniaturization and compactness of gas-fired power generation containers, making them suitable for more application scenarios such as field emergency response and vehicle-mounted mobility. At the same time, it eliminates the complex sealing structure of traditional electrical sealed cabinets, eliminating the need to disassemble a large number of sealing bolts or frequently replace sealing materials during maintenance. The operation process is more convenient and efficient, significantly reducing the overall cost of long-term use and maintenance of the equipment.

[0027] In one embodiment, such as Figures 1 to 2As shown, the gas-fired power generation container also includes a filter chamber 4 isolated from the generator compartment 1A and the electrical compartment 1B. The filter chamber 4 is equipped with filter elements 5, which are arranged in multiple stages along the gas flow direction, with the filtration diameter of each stage gradually decreasing. "Multiple stages" refers to two or more stages. The clean air purified by the filter chamber 4 can meet the usage requirements of both the electrical compartment 1B and the generator compartment 1A: satisfying the stringent requirements of the precision components of the electrical control system 3 for a dust-free and dry environment, while preventing dust from entering the gas generator set 2 and causing turbine blade wear. The filter chamber 4 is isolated from the generator compartment 1A and the electrical compartment 1B, preventing the back diffusion of impurities or potentially accumulated pollutants generated during filtration, thus not interfering with the air pressure balance and operating environment of the two compartments and ensuring the efficiency of the positive and negative pressure ventilation systems. The multi-stage filter elements 5 are arranged in a gradually decreasing filtration diameter order to prevent a single filter element 5 from quickly clogging due to overload, ensuring stable and long-lasting filtration performance and providing a clean air source for the positive pressure environment of the electrical compartment 1B and the negative pressure environment of the generator compartment 1A.

[0028] In one embodiment, such as Figure 1 As shown, the positive pressure ventilation system includes a centrifugal fan 6 and a ventilation duct 7. The centrifugal fan 6 is suitable for drawing filtered air from the filter chamber 4 and pressurizing it before delivering it to the ventilation duct 7. One end of the ventilation duct 7 is connected to the centrifugal fan 6, and the other end is connected to the electrical compartment 1B. The centrifugal fan 6 has a pressurization function, which provides power for air delivery, ensuring that the air in the ventilation duct 7 is injected into the electrical compartment 1B at a stable pressure and forms a continuous positive pressure. The stable positive pressure can effectively resist the reverse infiltration of external gases, while balancing the internal air pressure of the electrical compartment 1B, avoiding the impact of air pressure fluctuations on the protection effect, and ensuring the long-term stable operation of the electrical control system 3. In addition, the continuous and stable airflow can also remove the heat generated by the electrical components in the electrical compartment 1B, reduce the ambient temperature inside the compartment, delay the aging of components, improve the reliability of equipment operation, and reduce the risk of failure caused by overheating.

[0029] In one embodiment, such as Figure 2As shown, the negative pressure ventilation system includes an intake fan 8 and an exhaust fan 9. The intake fan 8 is suitable for drawing filtered air from the filter chamber 4 and delivering it to the unit compartment 1A, while the exhaust fan 9 is suitable for exhausting air from the unit compartment 1A. The intake fan 8 and the exhaust fan 9 are suitable for providing a negative pressure environment for the unit compartment 1A. The independent operation of the intake fan 8 and the exhaust fan 9 can flexibly control the negative pressure intensity through airflow adjustment. By controlling the exhaust volume to be greater than the intake volume, a stable negative pressure state can be formed and maintained in the unit compartment 1A, effectively preventing any possible leaked gas in the unit compartment 1A from spreading to the electrical compartment 1B, which has dense electrical components, and improving the exhaust efficiency after a gas leak, further reducing the explosion risk of the gas-fired power generation container. In addition, the filtered air delivered by the intake fan 8 can reduce the amount of dust and impurities entering the unit compartment 1A, reduce the probability of wear and blockage of internal components (such as turbines and filters) of the gas generator set 2, extend the service life of the equipment, and the continuous airflow circulation can promptly remove the high temperature generated by the operation of the gas generator set 2, avoid the excessively high ambient temperature in the unit compartment 1A from affecting the efficiency of the unit, and at the same time reduce the formation of condensate and reduce the risk of equipment moisture corrosion.

[0030] In one embodiment, such as Figure 1 As shown, the filter chamber 4 is stacked above the main container 1. The filter chamber 4 includes louvers 51 and a top plate structure 42. The louvers 51 are arranged circumferentially, with the lower side of the louvers 51 located on the main container 1 and the top plate structure 42 located on the upper side of the louvers 51. The top of the main container 1, the louvers 51, and the top plate structure 42 enclose the filter cavity 41, and multi-stage filter elements 5 are arranged in the filter cavity 41. The filter chamber 4 is stacked above the main container 1 without occupying the internal horizontal space of the main container 1, and does not affect the equipment layout and maintenance passage of the unit compartment 1A and electrical compartment 1B, further improving the overall space utilization of the container. The circumferentially arranged louvers 51 have both ventilation and protection functions, expanding the air collection range and efficiently introducing external air from multiple directions, improving air intake efficiency, providing sufficient air source for the filtration system and subsequent ventilation system, and at the same time, initially blocking the direct intrusion of large particulate impurities and rainwater. The top plate structure 42, together with the louvers 51 and the top of the main box 1, forms a filter chamber 41, which can protect the internal filter element 5 from external damage such as sun exposure, rain, and impact, and extend the service life of the filter system.

[0031] Furthermore, in one embodiment, such as Figure 2As shown, filter element 5 includes a primary filter and a secondary filter. The intake fan 8 is located after the primary filter and is suitable for drawing air from the filter chamber 4 after it has been filtered by the primary filter. The centrifugal fan 6 is located after the secondary filter and is suitable for drawing air from the filter chamber 4 after it has been filtered by the secondary filter. Because the electrical components in the electrical compartment 1B are densely packed, fine dust needs to be filtered to prevent damage to precision parts, thus requiring higher air cleanliness. Meanwhile, the unit compartment 1A needs to quickly exhaust any leaked gas and ensure heat dissipation, placing greater emphasis on ventilation and air exchange efficiency. By using the design of drawing primary filtered air from the intake fan 8 and secondary filtered air from the centrifugal fan 6, the electrical compartment 1B can obtain an air source that meets its high cleanliness requirements, while also satisfying the large air volume requirements of the unit compartment 1A. This effectively avoids air volume competition (such as high-resistance fine filtration affecting the air exchange efficiency of the unit compartment 1A) or cleanliness redundancy (such as energy waste caused by over-filtration of the air in the unit compartment 1A) that may occur under a single filtration path. This application can ensure the long-term efficient operation of the ventilation system based on accurately matching the differentiated needs of the unit compartment 1A and the electrical compartment 1B.

[0032] In one embodiment, such as Figure 2 As shown, the intake fan 8 and exhaust fan 9 are respectively located on opposite sides of the main housing 1 along its length, forming a straight airflow channel that runs through the unit compartment 1A. This ensures a smooth airflow path and wide coverage, effectively avoiding dead zones in the airflow. It also reduces the disturbance and dust accumulation caused by airflow reversals, improving ventilation efficiency and heat dissipation. Furthermore, it creates a balanced pressure gradient, helping to maintain a stable negative pressure environment in the unit compartment 1A and reducing the probability of gas diffusion into the electrical compartment 1B. Simultaneously, it fully utilizes the space on the side of the housing, without occupying the core installation and maintenance area within the compartment, and the separate placement of the fans facilitates independent maintenance without interference. It should be noted that... Figure 2 To clearly demonstrate the exhaust fan 9, a virtual window is shown on the partition between the filter chamber and the main housing; this virtual window is for illustrative purposes only and does not exist in the actual product. Figure 2 This is for illustrative purposes only and should not be used as a basis for interpreting the actual condition of the product.

[0033] In one embodiment, such as Figure 1As shown, the electrical compartment 1B is formed by welding together multiple protective partitions 10, or by welding together the protective partitions 10 and the side wall of the main enclosure 1. Welds are formed at the welded joints of the protective partitions 10, and the weld penetration depth (total volume of the electrical compartment / total volume of the main enclosure) is within the range of 0.76 mm⁻¹ to 4.55 mm⁻¹. For example, the weld penetration depth (total volume of the electrical compartment / total volume of the main enclosure) can be 0.76, 0.85, 0.94, 1.08, 1.22, 1.37, 1.52, 1.69, 1.86, 2.04, 2.23, 2.43, 2.64, 2.86, 3.09, 3.33, 3.58, 3.84, 4.11, 4.39, 4.55, or values ​​within any two of the above ranges. Gas inside electrical compartment 1B can leak into unit compartment 1A via weld seams. The weld penetration depth determines the depth of material the leak needs to penetrate. When the pressure difference across the weld seam (positive pressure - negative pressure) is within a fixed range, a greater weld penetration depth results in greater leakage resistance. A weld penetration depth satisfying this formula provides sufficient leakage resistance, effectively preventing gas leakage from electrical compartment 1B through the weld seam, ensuring a stable positive pressure environment, guaranteeing the safe operation of the electrical control system 3, and simultaneously preventing excessively thick protective partitions 10, meeting the requirements of compact equipment design and improving the space utilization of the main housing 1. If this ratio is less than 0.76mm... -1 This means that excessive weld penetration or insufficient volume in the electrical compartment 1B will result in an overly thick protective partition 10, occupying too much space and hindering the miniaturization and vehicle-mounted mobility of the gas-fired power generation container; if the ratio is greater than 4.55mm... -1 If the weld penetration is too shallow or the volume of electrical compartment 1B is too large, the gas leakage resistance will be insufficient, making it difficult to maintain a stable positive pressure in electrical compartment 1B. This can easily lead to risks such as contaminant intrusion and contact with flammable gases, resulting in protection failure. Preferably, the ratio of the total volume of electrical compartment 1B to the total volume of main enclosure 1 is in the range of 0.045 to 0.2. For example, it can be 0.045, 0.0, 0.06, 0.068, 0.076, 0.084, 0.092, 0.1, 0.108, 0.116, 0.124, 0.132, 0.14, 0.148, 0.156, 0.164, 0.172, 0.18, 0.188, 0.196, 0.2, or values ​​within the range of any two of the above values.

[0034] In one embodiment, such as Figure 3As shown, the first side wall 11 of the main housing 1 is provided with an opening 12 that can be opened or closed. The electrical compartment 1B is formed by a portion of the first side wall 11 and a protective partition 10. The orthographic projection of the protective partition 10 on the first side wall 11 at least partially coincides with the opening 12. Specifically, multiple maintenance doors can be installed on the first side wall 11 of the main container 1, forming a corresponding or even one-to-one layout with the electrical compartment 1B. When electrical components in the electrical compartment 1B need maintenance or replacement, there is no need to enter the container, disassemble the container structure, or interfere with the operation of the unit compartment 1A. The corresponding maintenance door can be opened directly from the outside of the container to access the electrical control system 3 and related components in the electrical compartment 1B, enabling targeted maintenance and replacement operations. This greatly simplifies the maintenance process, shortens downtime, reduces the maintenance difficulty and labor intensity in field operation scenarios, and allows the maintenance door to be quickly closed after maintenance, ensuring the airtightness of the electrical compartment 1B and not affecting its positive pressure environment maintenance and "three-proof" protection effect. At the same time, the design of multiple maintenance doors can adapt to the component maintenance needs of different areas in the electrical compartment 1B, further improving operational flexibility and efficiency.

[0035] In one embodiment, such as Figure 1 As shown, the protective partition 10 has a through-hole 13 extending through its thickness. A cable passes through the through-hole 13, and a sealing structure is installed inside the through-hole 13, sealing the space between the protective partition and the cable. The sealing structure between the inner wall of the through-hole 13 and the cable ensures the sealing integrity of the electrical compartment 1B and the stability of the positive pressure environment. It also reduces the erosion of the cable by dust and moisture and the frictional wear between the hole wall and the cable, thus reducing the risk of line failure.

[0036] In one embodiment, a gas detection unit is installed inside the electrical compartment 1B. This gas detection unit is electrically connected to the electrical control system 3 and is suitable for monitoring the gas concentration within the electrical compartment 1B and transmitting the results to the electrical control system 3. The gas detection unit continuously monitors the concentration of hazardous gases within the electrical compartment 1B. If leaked gas from the unit compartment 1A seeps in and exceeds the limit, a signal can be transmitted to the electrical control system 3, triggering an alarm or emergency shutdown measures in a timely manner. Furthermore, a pressure detection unit is installed inside the electrical compartment 1B and is electrically connected to the electrical control system 3. This pressure detection unit is suitable for detecting the pressure within the electrical compartment 1B and transmitting the results to the electrical control system 3. The pressure detection unit provides real-time feedback of the pressure data within the electrical compartment 1B, ensuring that it is always maintained within the set positive pressure range, and promptly detecting pressure abnormalities caused by weld leaks, seal failures, or centrifugal fan 6 malfunctions.

[0037] In one embodiment, such as Figure 1As shown, the electrical compartment 1B is divided into multiple sections, and the multiple electrical compartments 1B are connected by inter-compartment ventilation ducts 71. The multiple separated electrical compartments 1B can be arranged according to the functions of electrical components (such as control modules, power distribution units, etc.) to reduce mutual interference between components in different areas. If a local gas leak or dust contamination occurs in a certain area, the separation structure can slow down the diffusion rate, buy time for the detection unit to respond and handle emergencies, and reduce the overall risk. The interconnection design of the inter-compartment ventilation ducts 71 can balance the air pressure between the electrical compartments 1B, avoid positive pressure fluctuations caused by differences in sealing or local gas consumption in a single compartment, and ensure that all zones are maintained within the set positive pressure range.

[0038] According to an embodiment of this application, another aspect provides a dustproof, waterproof, and explosion-proof method for a gas-fired power generation container, comprising the following steps: Step one, checking the gas-fired power generation container for structural and sealing abnormalities. Specifically, the inspection of the structure and sealing may include checking the structure and sealing of the filter chamber 4: checking the structure of the louvers 51, such as whether they are deformed, damaged, or stuck, preventing normal ventilation or blocking impurities; checking the filter elements 5, such as whether the filter elements 5 are clogged, damaged, deformed, or loosely installed, or have foreign objects accumulating, affecting airflow or filtration effect; and also... This includes inspecting the outer wall of the main enclosure and the main enclosure inspection door, checking for holes, cracks, or other damage to the electrical compartment 1B protective partition 10, and ensuring that the inter-compartment ventilation pipe 71 and its connections are secure and free from leaks. Once no abnormalities are found, proceed to step two. If any abnormalities are found, stop proceeding to the next step, record the abnormality, take corresponding corrective measures, and then proceed to step two. Specifically, the corresponding measures could be: correcting structural deformation if it is found; repairing or replacing seals if they are found to be damaged; tightening loose connections if they are found to be loose; and clearing blocked ventilation openings if they are found to be blocked.

[0039] Step two involves activating the positive pressure ventilation system to purge the electrical compartment 1B. In one embodiment of this application, a centrifugal fan 6 can be activated to extract clean air filtered by the secondary filter in the filter chamber 4 and send it into multiple interconnected electrical compartments 1B through the ventilation duct 7 to thoroughly purge the interior of the electrical compartments 1B and remove residual dust, moisture, and any trace amounts of combustible gas that may be present.

[0040] Step 3 is to start the negative pressure ventilation system to exhaust the air from unit compartment 1A. In one embodiment of this application, the intake fan 8 and the exhaust fan 9 are turned on simultaneously. The intake fan 8 draws the air filtered by the primary filter in the filter chamber 4 and sends it into unit compartment 1A. The exhaust fan 9 discharges the air from the other side of the main housing 1, forming a through airflow to exhaust the air from unit compartment 1A, replace the internal air and reduce the risk of gas accumulation.

[0041] Step four involves the electrical control system 3 checking whether the start-up requirements are met after a first preset time using its configured gas detection unit. If the start-up requirements are met, the gas generator set 2 in unit compartment 1A is started. The first preset time ensures that residual hazardous gases (dust, water vapor, combustible gases) in electrical compartment 1B and unit compartment 1A are completely replaced by clean air, preventing insufficient purging from causing the accumulation of hazardous substances. In one embodiment of this application, after purging for the first preset time (e.g., 30 minutes, which can be adjusted according to actual operating conditions), the electrical control system 3 obtains hazardous gas concentration data through the gas detection unit in electrical compartment 1B. If the detection result meets the preset start-up safety threshold (e.g., combustible gas concentration is below 10% of the lower explosive limit), the start-up requirements are determined to be met, and the gas generator set 2 in unit compartment 1A is started. If the requirements are not met, the process returns to step 2 for re-purging.

[0042] Step 5 is that after the gas generator set 2 is started, the positive pressure ventilation system continues to work to maintain the positive pressure state of the electrical compartment 1B. During the operation of the gas generator set 2, the centrifugal fan 6 continues to work to continuously deliver clean air to the electrical compartment 1B, so that the electrical compartment 1B always maintains the set positive pressure state, and the air pressure difference prevents external dust, moisture and gas that may leak from the unit compartment 1A from entering.

[0043] Step six involves shutting down the gas generator set 2, keeping the centrifugal fan 6 running until the temperature inside the main housing 1 drops to the preset temperature. Then, the positive pressure ventilation system is shut down to confirm there are no high-temperature hazards inside the housing and the gas concentration is stable. Finally, the centrifugal fan 6 is turned off, completing the entire dustproof, waterproof, and explosion-proof process. The preset temperature can be flexibly set according to the actual application scenario (e.g., close to ambient temperature (ambient temperature ± 5℃), meeting the temperature threshold for safe equipment shutdown, etc.). This entire workflow provides three-proof protection for the gas-fired power generation container, adapting to the safe operation requirements in complex working conditions such as in the field, and ensuring the safety and stability of the gas-fired power generation container's operation.
