Description

Technical Field

[0001] This utility model relates to the field of fuel supply technology, and in particular to a redundant fuel supply device for airport emergency lighting diesel generator sets that ensures continuous power supply. Background Technology

[0002] Airport emergency lighting systems are core infrastructure for ensuring flight takeoff and landing scheduling, emergency passenger evacuation, and ground operation safety. The continuity of their power supply is directly related to airport operational safety and public safety. Diesel generator sets, as key backup power sources for airport emergency lighting, need to start immediately and operate stably in scenarios such as power outages, extreme weather, or sudden failures. The reliability and adaptability of the fuel supply device are the core guarantees for the uninterrupted operation of the generator sets.

[0003] However, existing technologies still have shortcomings. When adapting to the special scenarios of airports, the redundant fuel supply devices of existing diesel generator sets still have many technical defects and cannot meet the high requirements for continuous power supply for emergency lighting. 1. Low efficiency in pipeline connection and maintenance: The existing oil supply system's pipeline connections mostly adopt traditional threaded wrapping with PTFE tape, flange gasket sealing, or snap-fit ​​connection structures. Installation requires complex steps such as cleaning, wrapping with sealing material, and symmetrically tightening bolts. Disassembly requires the assistance of professional tools. Not only is the operation cumbersome and time-consuming, but long-term exposure to strong vibrations from the airport ground can easily lead to problems such as loose joints and seal failure. Subsequent maintenance requires shutdown, which seriously affects emergency response efficiency. At the same time, the complex structure of the connection parts also increases the risk of air entering the oil circuit, leading to difficulties in starting the generator set or interruption of operation.

[0004] 2. Shortcomings in fuel filtration and impurity removal: Airport emergency generator sets have long fuel storage periods, and impurities may be introduced due to transportation and storage environments. At the same time, diesel fuel is prone to grease clumping during long-term storage or temperature changes. The existing fuel supply system's filter structure is mostly a fixed-installation filter element, which has insufficient filtration accuracy and is inconvenient to disassemble and install. Clumped grease and impurities can easily clog pipelines, filters, or fuel pumps, leading to insufficient fuel supply or even complete fuel supply interruption, causing generator set shutdown failure. Cleaning clogged filter elements requires disassembling multiple connecting parts, which is cumbersome and has a long maintenance cycle, making it impossible to quickly restore the function of the fuel supply system.

[0005] 3. Poor adaptability to low-temperature environments: Airports often face extreme low-temperature environments below -40℃. Diesel fuel will experience reduced fluidity, solidification, or freezing at low temperatures. Existing fuel supply systems lack targeted insulation designs and rely solely on fuel grade adjustment or external heating assistance. This not only has limited insulation effects but may also lead to pipeline blockage, reduced fuel pump efficiency, or even fuel freezing and inability to supply fuel due to fuel solidification. This seriously affects the reliability of generator set's low-temperature start-up and continuous operation. At the same time, low temperatures can also cause water in the fuel tank to precipitate and form ice crystals, further exacerbating the risk of fuel line blockage.

[0006] Therefore, we propose a redundant fuel supply device for airport emergency lighting diesel generator sets to ensure continuous power supply in order to solve this problem. Utility Model Content

[0007] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a redundant fuel supply device for airport emergency lighting diesel generator sets that ensures continuous power supply.

[0012] Preferably, the cap is fixed by a fixing rotating block.

[0013] In this utility model, a redundant fuel supply device for an airport emergency lighting diesel generator set that ensures continuous power supply is described. This device comprises a support column, fuel tank, fuel filler pipe, motor, stirring rod, fuel outlet pipe, No. 1 threaded ring, No. 1 connecting pipe, mounting ring, No. 1 threaded shell, outer shell, hinge, cap, No. 2 threaded ring, No. 2 threaded shell, filter cartridge, No. 1 mounting plate, No. 2 mounting plate, fixed rotating block, No. 2 connecting pipe, and flange ring. When installing the No. 1 connecting pipe, it is pushed into the fuel outlet pipe. Then, the No. 1 threaded shell is rotated to fit onto the outer surface of the No. 1 threaded ring, thus fixing the No. 1 connecting pipe. The No. 2 connecting pipe is connected to the fuel pump via the flange ring. The fuel in the tank passes through the filter cartridge, which filters the fuel, effectively preventing grease buildup from clogging the pipes and affecting the normal operation of the fuel supply device. Rotating the fixed rotating block moves the fixed rotating block from the No. 2 connecting pipe... The filter cartridge can be removed from the mounting plate by turning the No. 2 threaded housing to open the cover. Rotating the No. 2 threaded housing allows the filter cartridge to be removed from the outer casing, enabling cleaning of any impurities inside. This system eliminates the need for sealing materials or specialized tools; simply rotating the threaded housing secures the pipeline, significantly simplifying the installation process. The threaded connection, combined with the flange sealing structure, provides strong resistance to strong ground vibrations, preventing loosening of joints and seal failure, reducing the risk of air entering the oil circuit, and allowing for maintenance without downtime. It supports rapid online disassembly and assembly, ensuring continuous emergency power supply. The filter cartridge effectively intercepts clumps of grease and impurities in the diesel fuel, preventing blockages in pipelines and pumps at the source and ensuring smooth fuel supply. When the filter cartridge becomes clogged, simply rotate the fixing block to open the cover and unscrew the No. 2 threaded housing to remove the filter cartridge. The cleaning operation is simple and quick, significantly shortening the maintenance cycle and rapidly restoring the fuel supply system's functionality. In this utility model, the redundant fuel supply device for airport emergency lighting diesel generator set that ensures continuous power supply can continuously provide heat protection for diesel fuel in the fuel tank by setting up heat insulation rods. This effectively avoids the diesel fuel from becoming less fluid, solidifying, or freezing in low-temperature environments, while reducing the risk of water in the fuel tank precipitating and forming ice crystals. This ensures that the diesel generator set can still start stably and supply fuel continuously in extreme low-temperature scenarios such as -40℃. This utility model has a reasonable structural design, is simple to operate, and has high reliability. Attached Figure Description
