[0030] To address the problem that existing compressed air power generation devices have their power and air pressure output interfaces located inside the housing, which increases maintenance difficulty, this application provides a compressed air power generation device.

[0031] like Figures 1 to 4As shown, the compressed air generator includes a housing 10, a generator set 20, an air compressor unit 30, a power output interface 40, and a pressure output interface 50. The housing 10 has a first mounting hole 17, a second mounting hole 18, and a receiving cavity, both of which communicate with the receiving cavity. The generator set 20 is disposed within the receiving cavity and includes a diesel engine 21 and a generator 22. The flywheel of the diesel engine 21 is driven by the drive end of the generator 22, causing the generator 22 to generate current by rotating the drive end. The air compressor unit 30 is disposed within the receiving cavity. The power output interface 40 is located at the first mounting hole 17. The first output end of the generator 22 is connected to the power output interface 40, and the second output end of the generator 22 is electrically connected to the air compressor unit 30 to supply power to the air compressor unit 30. The pressure output interface 50 is located at the second mounting hole 18 and communicates with the exhaust port of the air compressor unit 30.

[0032] Applying the technical solution of this embodiment, the power output interface 40 and the air pressure output interface 50 are respectively located at the first mounting hole 17 and the second mounting hole 18 of the housing 10, facilitating direct connection of external equipment by the user. Maintenance and inspection can be performed without opening the housing 10, which not only reduces operational complexity and time consumption but also improves operational convenience and safety. This solves the problem in the prior art where the power and air pressure output interfaces of the compressed air generator are both located inside the housing, increasing maintenance difficulty. Simultaneously, the power generated by the generator 22 is used not only for external power output but also to power the air compressor unit 30, achieving internal power recycling. Furthermore, the output of the generator 22 is divided into two paths: one directly supplies external power demand, and the other is used for the operation of the air compressor unit 30. This design optimizes energy distribution, ensures a stable supply of power and compressed air, and also facilitates adjustment of the power and compressed air output ratio according to actual needs.

[0033] like Figure 2 As shown, the compressed air generator also includes a level gauge 60, which is mounted on the housing 10 to display the amount of diesel fuel in the diesel engine 21. The level gauge 60, power output interface 40, and air pressure output interface 50 are located on the first side of the housing 10. This arrangement of the level gauge 60, power output interface 40, and air pressure output interface 50 on the same side eliminates the need for operators to walk around the equipment when checking the diesel fuel level or connecting external power or air pressure equipment, saving operation time, improving work efficiency, enhancing operational convenience and safety, and optimizing equipment layout and maintenance. Furthermore, the centralized layout facilitates quick access to these critical components for maintenance personnel, reducing maintenance costs.

[0034] In this embodiment, the external display function of the level gauge 60 eliminates the need for operators to frequently open the housing 10 to check the diesel fuel level, thereby reducing the number of times the equipment is opened and closed. This avoids potential degradation of the housing's sealing or damage to internal components due to frequent opening and closing, extending the equipment's service life. Furthermore, by centrally designing frequently used and monitored components on the first side of the housing 10, the external layout of the equipment is optimized, improving its aesthetics and user-friendliness. The design also considers user habits and needs, reflecting the principle of human-centered design.

[0035] like Figure 2 and Figure 4 As shown, the housing 10 also has an installation port, an oil inlet 11, and a drain port 12. The oil inlet 11 is used to inject diesel fuel, and the drain port 12 is used to discharge oil sludge from the diesel engine 21. The compressed air generator also includes a control panel 70, which is located at the installation port. The control panel 70 includes a display device and a control module. The control module is electrically connected to both the diesel engine 21 and the air compressor unit 30 to control their start-stop status. The installation port, oil inlet 11, and drain port 12 are all located on the first side of the housing 10. By concentrating all the critical maintenance and operation interfaces (such as the installation port, oil inlet 11, and drain port 12) and the control panel 70 on the first side of the housing 10, it greatly facilitates equipment maintenance and adjustment for operators. Daily diesel fuel replenishment, oil sludge discharge, and equipment start-up and shutdown operations can be completed without bypassing the entire device, significantly improving work efficiency. Meanwhile, the integrated design of the control panel 70 and the maintenance access port allows operators to monitor and control the equipment's operating status while maintaining a safe distance. This reduces the risk of operators directly contacting hazardous internal components and improves safety during operation.

[0036] In this embodiment, the operator can monitor and adjust the operation of the entire device through the control panel 70, including the oil level of the diesel engine and the compressed air output of the air compressor, so as to achieve comprehensive management of the equipment's operating status.

[0037] like Figure 4As shown, the compressed air power generation device also includes a control module. The air compressor unit 30 includes a compressor 31, a first radiator 32, and a temperature detection device. The first radiator 32 includes a fan for cooling the compressor 31. The temperature detection device is electrically connected to the control module to detect the exhaust temperature of the compressor 31. Specifically, when the detected temperature is greater than or equal to 85°C, the control module controls the fan to start; when the detected temperature is less than or equal to 75°C, the control module controls the fan to stop. This temperature-based automatic fan control mechanism ensures that the fan only operates when necessary. Specifically, when the exhaust temperature of the compressor 31 is below a threshold (e.g., 75°C), the fan automatically stops, reducing unnecessary energy consumption, extending the lifespan of the fan and other related components, and improving the overall system's energy efficiency ratio.

[0038] In this embodiment, by monitoring the exhaust temperature of the compressor 31 in real time, overheating can be responded to promptly. Once the temperature reaches or exceeds a preset upper limit (e.g., 85°C), the fan immediately starts to quickly cool the compressor 31, preventing performance degradation or equipment failure due to overheating and ensuring the stable operation of the compressor and the entire device.

[0039] Specifically, by combining fan control with compressor temperature monitoring to achieve automated heat dissipation management, the operating efficiency and stability of the "compressed air power generation device" are improved, and energy is saved and costs are reduced during long-term operation.

[0040] like Figure 4 As shown, the air compressor unit 30 also includes a first filter device 33 and an oil-gas separator 34. The first filter device 33 is located at the air inlet of the compressor 31 to filter impurities in the air entering the inlet. The oil-gas separator 34 is located at the air outlet of the compressor 31 to separate the gas-liquid mixture discharged from the air outlet. A first radiator 32 is located downstream of the oil-gas separator 34 to cool the separated gas. By placing the first filter device 33 at the air inlet of the compressor 31, impurities and particles in the air can be effectively filtered, ensuring the cleanliness of the air entering the compressor 31. This not only improves the purity of the compressed air but also reduces wear on internal compressor components caused by impurities, improving compression efficiency and extending the lifespan of the compressor 31. Simultaneously, the oil-gas separator 34, located at the air outlet of the compressor 31, can efficiently separate oil and air from the gas-liquid mixture generated during compression. This separation process is crucial for ensuring the quality of the output compressed air, while also recovering and treating lubricating oil, preventing oil pollution and improving the environmental performance of the equipment.

[0041] In this embodiment, the first radiator 32 is located downstream of the oil-gas separator 34 to cool the separated compressed air. By lowering the air temperature, the moisture content in the compressed air can be reduced, increasing its dryness. Simultaneously, through the aforementioned air filtration, oil-gas separation, and compressed air cooling steps, the operating environment of the entire air compressor unit 30 is optimized, reducing wear and corrosion of internal components, thereby extending the equipment's service life and reducing the frequency of maintenance and upkeep, thus lowering maintenance costs.

[0042] like Figure 4 As shown, the air compressor unit 30 also includes an air storage device 35, located at the exhaust port of the oil-gas separator 34, for storing the gas separated by the oil-gas separator 34. The air storage device 35 is connected to the air pressure output interface 50. Thus, the air storage device 35 can store a certain amount of compressed air, ensuring a continuous and stable supply of compressed air even when the compressor 31 temporarily stops operating or operates unstablely, meeting the continuous compressed air supply requirements of industrial applications. Simultaneously, through the storage function of the air storage device 35, the high-pressure airflow instantaneously generated by the compressor 31 can be buffered, reducing compressed air pressure fluctuations and improving the pressure stability and quality of the output compressed air.

[0043] like Figures 1 to 3 As shown, the housing 10 includes a chassis 13, an oil tank 14, and a canopy 15. The chassis 13 has a drain port 12, and the oil tank 14 is mounted on the chassis 13 for supplying fuel to the diesel engine 21. The canopy 15 is mounted on the chassis 13 to form a receiving cavity around the chassis 13. The first mounting hole 17, the second mounting hole 18, and the mounting opening are all located on the canopy 15. This arrangement of the first mounting hole 17, the second mounting hole 18, and the mounting opening on the canopy 15 helps optimize the internal and external spatial layout of the equipment. This centralized design reduces the length and complexity of connecting pipelines, resulting in a more compact overall layout, less space occupation, and easier installation and operation within a limited space. Simultaneously, the receiving cavity formed by the canopy 15 and the chassis 13 provides physical protection for the internal components of the equipment, reducing the impact of external factors on the equipment.

[0044] In this embodiment, the housing 10 achieves the goals of integration, safety and optimized space utilization of the "compressed air power generation device" through the combined design of the chassis 13, oil tank 14 and canopy 15, as well as the reasonable layout of key orifices and interfaces, while ensuring that the equipment is easy to operate, maintain and move.

[0045] Optionally, the chassis 13 and / or the canopy 15 may be made of aluminum alloy. Aluminum alloy has a high strength-to-weight ratio, and compared to traditional materials such as steel, using aluminum alloy for the same structure can significantly reduce the weight of the equipment, improving its mobility and operational efficiency.

[0046] In this embodiment, both the chassis 13 and the canopy 15 are made of aluminum alloy.

[0047] like Figure 3 As shown, the compressed air generator also includes a connecting assembly 80, which includes a base 81 and fasteners 82. The base 81 is mounted on the chassis 13 and has a third mounting hole. The fasteners 82 pass through the third mounting hole and the base to mount the compressed air generator on the base. In this way, the base 81 and fasteners 82 work together to stably fix the compressed air generator on the base. Even if vibration or impact occurs during operation, the equipment will not easily shift or be damaged, improving the stability and safety of the overall system. At the same time, the above-mentioned design of the connecting assembly 80 makes the installation process simpler and faster. The operator only needs to place the base 81 in the predetermined position on the chassis 13, and then pass the fasteners 82 through the third mounting hole and the corresponding hole in the base to complete the installation of the equipment. No complex welding or other fixing processes are required, reducing installation difficulty and time costs.

[0048] Alternatively, fastener 82 may be a screw or bolt.

[0049] Optionally, there may be one connecting component 80; or, there may be multiple connecting components 80, spaced apart along the length and / or width of the chassis 13. This arrangement allows for greater flexibility in selecting the number of connecting components 80 to meet different usage requirements and operating conditions, and also improves the processing flexibility for operators. Furthermore, having multiple connecting components 80 enhances the connection stability between the compressed air generator and the base, preventing separation or displacement that could affect the connection stability of the compressed air generator.

[0050] In this embodiment, there are four connecting components 80, which are spaced apart along the length and width of the chassis 13.

[0051] It should be noted that the number of connecting components 80 is not limited to this and can be adjusted according to working conditions and usage requirements.

[0052] Optionally, the connecting components 80 may be two, three, five, six, or more.

[0053] Optionally, the canopy 15 also has an air inlet 151 and an air outlet 152, with a grille 16 provided at the air inlet 151 and / or the air outlet 152; and / or, the generator set 20 further includes a second radiator 23 for cooling the diesel engine 21; and / or, the generator set 20 further includes a second filter 24, which is located at the air inlet of the diesel engine 21 to filter impurities in the air entering the air inlet. In this way, the second radiator 23 cools the diesel engine 21, improving the heat dissipation efficiency of the diesel engine under long-term, high-load operation, thereby ensuring the operational stability of the diesel engine and extending its service life. Furthermore, the design of the air inlet 151 ensures that sufficient cold air can flow into the canopy 15, providing the necessary cooling medium for the second radiator 23. Simultaneously, the second filter 24, located at the air inlet of the diesel engine 21, can effectively filter out impurities and particles in the air, providing clean air for the diesel engine to burn. Clean air not only improves combustion efficiency and reduces harmful emissions, but also protects internal diesel engine parts from contamination and corrosion, maintaining the healthy operation of the system.

[0054] In this embodiment, the generator set 20 further includes a second radiator 23 and a second filter device 24. The second radiator 23 is used to cool the diesel engine 21. The second filter device 24 is disposed at the air intake of the diesel engine 21 to filter impurities in the air entering the air intake.

[0055] like Figure 2 As shown, the compressed air generator also includes an emergency stop switch 90, which is disposed on the housing 10 and located on the first side of the housing 10, for use in realizing emergency stop control of the compressed air generator.

[0056] like Figure 4 As shown, the generator set 20 also includes a muffler 25, which is located at the exhaust port of the diesel engine 21.

[0057] like Figure 2 As shown, the compressed air power generation device also has a lifting hole 19, which is located on the top of the shed 15. The crane lifts the compressed air power generation device through the lifting hole 19.

[0058] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0059] The compressed air generator includes a housing, a generator set, an air compressor unit, a power output interface, and a pressure output interface. The housing has a first mounting hole 17, a second mounting hole 18, and a receiving cavity, both of which communicate with the receiving cavity. The generator set is located within the receiving cavity and includes a diesel engine and a generator. The flywheel of the diesel engine is driven by the drive end of the generator, causing the drive end to rotate and generate current in the generator. The air compressor unit is also located within the receiving cavity. The power output interface is located at the first mounting hole 17. The first output end of the generator is connected to the power output interface, and the second output end of the generator is electrically connected to the air compressor unit to supply power to the air compressor unit. The pressure output interface is located at the second mounting hole 18 and communicates with the exhaust port of the air compressor unit. In this way, the power output interface and the air pressure output interface are respectively located at the first mounting hole 17 and the second mounting hole 18 on the housing, which facilitates direct connection of external equipment by the user. Maintenance and inspection can be carried out without opening the housing, which not only reduces the complexity and time consumption of operation, but also improves the convenience and safety of operation. This solves the problem of increased maintenance difficulty caused by the fact that the power and air pressure output interfaces of the compressed air generator are located inside the housing in the existing technology. At the same time, the power generated by the generator is not only used for external power output, but also for powering the air compressor unit, realizing the internal recycling of electricity. In addition, the output of the generator is divided into two paths: one path directly supplies the external power demand, and the other path is used for the operation of the air compressor unit. This design optimizes energy distribution, ensures a stable supply of electricity and compressed air, and also facilitates the adjustment of the output ratio of electricity and compressed air according to actual needs.
