Description

Technical Field

[0001] This utility model belongs to the field of tunnel emergency power supply technology, specifically relating to an intelligent diesel generator box suitable for tunnels. Background Technology

[0002] As a critical node in modern transportation networks, highway tunnels rely on a continuous and reliable power supply for their internal lighting, ventilation, fire protection, monitoring, and emergency communication systems. Normally, the main power source for tunnels is the municipal power grid. However, extreme weather, geological disasters, equipment failures, or human-caused accidents can lead to power outages. Once power is interrupted, the tunnel will be plunged into darkness, ventilation failure will cause the accumulation of harmful gases, and the monitoring system will fail, seriously threatening traffic safety and the lives of personnel. Therefore, diesel generator sets, as core equipment for backup power, have become an indispensable component of the tunnel's power supply and distribution system. After a municipal power outage, diesel generators can quickly start supplying power, ensuring the continuous operation of critical equipment and minimizing the risk of safety accidents.

[0003] During the construction phase, traditional diesel generators are mostly fixedly installed indoors in ground substations. Their construction requires pre-planning of independent machine rooms, occupies a large area, and takes several weeks to months to complete. Moreover, they are difficult to reuse or relocate. When faced with irregularly shaped spaces such as underground shafts and equipment chambers common in tunnel engineering, the large size and rigid structure of the equipment often require additional excavation or layout changes, leading to a surge in civil engineering costs and uncontrollable construction periods. This non-standardized "one machine, one design" approach severely restricts the convenience of using diesel generators in tunnel scenarios.

[0004] During operation, traditional diesel generators lack intelligent monitoring capabilities. Key parameters such as fuel level, coolant temperature, and output power rely on manual inspection, leading to data lag and the risk of missed inspections. The fault alarm mechanism is inadequate, hindering proactive early warning and making downtime accidents more likely due to untimely maintenance. Furthermore, routine inspections and maintenance require manual recording of generator start-up, shutdown, and operational status, necessitating frequent on-site visits. This is time-consuming, labor-intensive, and prone to missed inspections. The inability to generate real-time electronic reports results in low maintenance efficiency and difficulties in management and traceability. Utility Model Content

[0034] Preferably, the combined cabinet 16 is located at the far right of the rear end of the enclosure 1, the PLC is connected to the switch, the switch is connected to the server, and the server is connected to the remote monitoring platform.

[0035] Preferably, the radiator assembly 8 includes: an upper water tank 19, a radiator core 21, a lower water tank 20, coolant, a water pump, a fan, a liquid level sensor, a temperature sensor, and an engine speed sensor. The upper water tank 19 is located at the upper end of the radiator assembly 8 and is connected to the outlet pipe of the diesel generator 2. It is used to receive the high-temperature coolant generated during the operation of the diesel engine. The high-temperature coolant is introduced into the upper water tank 19 from the cylinder outlet of the diesel generator 2 through a flexible rubber hose or a metal corrugated pipe. The upper water tank 19 is connected to the radiator core 21 through its inner cavity. The lower part of the core 21 is connected to the lower water tank 20. The coolant flows from the upper water tank 19 into the finned tube bundle of the radiator core 21 for heat exchange. The radiator core 21 adopts an aluminum alloy or copper-aluminum composite structure, which has high thermal conductivity and good air permeability. The coolant is cooled by airflow here, and after the temperature drops by 10-15°C, it flows out from the finned tube bundle of the radiator core 21 and flows into the lower water tank 20, ready to return to the diesel generator 2 for continued circulation. The lower water tank 20 is connected to the inlet end of the water pump through a coolant return hose or metal pipe, and the outlet end of the water pump is connected through a short... A pipe or flange connects to the water inlet of the diesel generator 2. The water pump is driven by the crankshaft of the diesel generator 2 via a belt, forming a closed-loop circulation system. The fan is fixed to the back of the radiator core 21 and driven by the belt of the diesel generator 2 (or by an independent motor). When the fan is running, it draws in external cold air, passes through the core of the radiator core 21, and carries away the heat released by the coolant, improving heat dissipation efficiency. The liquid level sensor is located at the top of the upper water tank 19. If the liquid level is too low, it sends an alarm signal to the PLC or diesel generator controller 3, prompting the relevant authorities to activate the system. The system ensures timely replenishment of coolant to prevent dry burning. The temperature sensor is located in the middle of the radiator core 21, and the engine speed sensor is located at the flywheel or crankshaft of the diesel generator 2 to determine the linkage status between the engine speed and the water pump, thereby confirming the water pump's operating condition. The level sensor, temperature sensor, and engine speed sensor are all connected to the PLC. The radiator assembly 8 has a frame structure, integrating the upper water tank 19, radiator core 21, lower water tank 20, coolant, water pump, fan, level sensor, temperature sensor, and engine speed sensor into one unit.

[0036] In use, the PLC collects operating data from the diesel generator controller 3, temperature and humidity sensor 11, water immersion detector 12, oil level gauge 5, and fire extinguishing controller 13 via the Modbus-RTU bus, and controls the start and stop of the electric louvers 6 and the diesel generator 2, as well as the linkage action of the precision air conditioner 17 and the audible and visual alarm through digital output (DO); the switch carries the communication between the camera 10 and the smart access control 9, and connects to the server via the Ethernet port. The server then establishes communication with the MQTT platform of the tunnel monitoring center through a 4G / 5G industrial router or fiber optic ring network to realize remote operation and maintenance and control.

[0037] When the mains power fails, the PLC triggers the self-starting logic of the diesel generator 2: it outputs a DO instruction to switch the diesel generator controller 3 to automatic mode, and at the same time opens the electric louver 6. After the diesel generator 2 starts, the system monitors its key parameters such as speed, oil pressure, and cooling water temperature in real time. When the above operating parameters meet the set parallel operation conditions, the system automatically completes the load switching to realize emergency power supply.

[0038] During emergency operation, the PLC continuously monitors various operating parameters: when the oil level gauge 5 detects that the oil level is below the safety threshold, the temperature and humidity sensor 11 detects abnormal temperature and humidity inside the cabin, or the water immersion detector 12 detects liquid intrusion, the system will immediately issue an alarm signal, provide a local prompt through the audible and visual alarm, and upload the alarm information to the remote monitoring platform; the camera 10 will simultaneously capture abnormal images for remote inspection personnel to verify; the intelligent access control 9 will record entry and exit behavior and bind it to the platform's authorization mechanism to prevent unauthorized operations.

[0039] When the smoke detector 15 detects smoke or the camera 10 detects flame characteristics, the fire extinguishing controller 13 immediately enters a 10-second countdown process. During the countdown, the PLC will execute emergency shutdown measures: output control commands to stop the diesel generator 2, cut off the precision air conditioner 17 and all non-fire-fighting power supplies, and close the electric louvers 6 to block the combustion air. If the fire alarm signal is not cleared by the end of the countdown, the fire extinguishing controller 13 will automatically drive the perfluorohexanone extinguishing agent cylinder group 14 to spray the extinguishing agent through the top nozzle to complete the gas fire extinguishing in the confined space and ensure the safety of the equipment inside the enclosure.

[0040] After the fire alarm is handled, the system enters maintenance mode and needs to be manually inspected and confirmed before it can be restarted. If the mains power is restored, the PLC will automatically switch back to mains power supply after judging that the voltage is stable, control the diesel generator 2 to shut down normally, and at the same time delay the closing of the electric louvers 6 and the fan to ensure that the residual heat is completely discharged. All operating data, alarm information and fire extinguishing records are uploaded to the server and transferred to the remote platform to realize closed-loop operation and maintenance management.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made to it.
