Referring to fig. 5, the utility power supply device in the invention comprises a power supply device main body (3), wherein a plurality of power supply sockets (2) for ground protection equipment are arranged on the power supply device main body (3), a ground protection cover (1) is arranged at the top of the power supply device main body (3), the power supply device main body (3) is arranged below the ground of the parking apron in a lifting manner, the power supply device main body (3) is lifted after the ground protection cover (1) is opened, and the power supply device main body (3) is closed and covered by the ground protection cover (1) after being lowered. The utility power supply device is an embedded type utility power supply device, and is an embedded type special lifting and turning device paved on an apron. The utility model has the function of conveying electric energy into the utility model through an underground electric power pipe network and then connecting the utility model to energy storage type electric (or fuel oil type) airport ground guarantee equipment, and providing machine leaning operation power for the energy storage type electric (or fuel oil type) airport ground guarantee equipment.
According to the method, the method for setting the embedded type commercial power supply device special for the aircraft apron on the aircraft apron is realized by the position of the interface of the aircraft apron on the aircraft stand according to the operation of different aircraft types and the operation position of the airport ground guarantee equipment.
1. The invention solves the problem of safety of the ground guaranteeing equipment of the energy storage type electric airport by machine operation, namely when the ground guaranteeing equipment of the energy storage type electric airport by machine operation, an energy storage battery carried by the ground guaranteeing equipment is not used, and the ground guaranteeing equipment is powered by mains supply, and the energy storage battery is in a static state or a low chemical reaction state at the moment, so that the risk hidden danger caused by inflammability and explosiveness of the energy storage battery is greatly reduced, and the safety margin of an aircraft, passengers, ground operation guaranteeing personnel and the ground guaranteeing equipment of the energy storage type electric airport is greatly improved.
2. The invention solves the problems of shorter endurance mileage, longer charging time needed each time, short interval time of the required charging times and short time of actually using the energy storage battery of the equipment caused by the working mode that the energy storage battery is used as a power source by the energy storage type electric airport ground protection equipment for the original running and the leaning operation. The working mode of using the energy storage battery when the equipment walks, namely using commercial power when the equipment is used for guaranteeing operation by a machine, the working time of the energy storage battery is shortened relative to that of guaranteeing operation each time, so that the use times and time of the whole battery are increased, and the effective working time of the energy storage battery for completing guaranteeing operation by one-time charging is prolonged.
3. The invention solves the problem of higher purchase cost of the ground guarantee equipment of the energy storage type electric airport, and the original working mode is to always provide kinetic energy by the energy storage batteries, so that the quantity of the energy storage batteries is relatively great. By adopting a new working mode, the actual working time of the energy storage battery can be greatly shortened, so that the number of the original energy storage batteries can be properly reduced, the integral weight of the equipment is lightened, and the energy consumption of the equipment in driving and walking is reduced. The new operation mode can reduce the number of the energy storage batteries, reduce the purchase cost of the energy storage batteries and also reduce the whole vehicle purchase cost of the energy storage type electric airport ground protection equipment.
4. The invention solves the problem of the contradiction between the allocation quantity of the airport charging piles and the supply and demand shortage of the quantity ratio of the ground guarantee equipment of the energy storage type electric airport. Because the energy-saving and emission-reducing requirements, the number of the ground guarantee devices of the energy-storage electric airport can be gradually increased, the number of the charging piles is also synchronously increased according to the proportion of the piles and the devices, but the space resources of the air side ground of the airport are limited, the requirement of the number of the charging piles cannot be completely met for arrangement and installation, and the popularization of the electric guarantee devices can be influenced. In addition, some charging piles are arranged and installed unreasonably, so that the distance between the ground guarantee equipment of the energy storage type electric airport and the charging piles, which is arranged on the apron, is longer, the effective acting of the energy storage battery of the equipment is greatly reduced, the operation efficiency of the part of the guarantee equipment is low, and the use efficiency of the equipment is reduced.
Because the low-voltage power distribution cabinet (power distribution booth) of the existing apron stand is arranged near the high-pole lamp of the apron and is far away from the place where the airplane is parked, if the commercial power is taken from the low-voltage power distribution cabinet to provide power for airport ground guarantee equipment, the cables on the airport ground guarantee equipment need to be pulled out for a long distance, and the time for pulling out or retracting the cables is too long, so that the time specified by guarantee operation is influenced, and the operation safety specification of the apron is not met.
5. The invention solves the problems of shorter endurance mileage, longer refueling time per time, short interval time of refueling times and short time of actually available fuel engines of the equipment caused by the working mode that the fuel type airport ground assurance equipment completely uses the fuel engines as power sources in the original running and leaning operation. The working mode of using the fuel engine when the equipment walks, namely using the commercial power when the operation is ensured by a machine, shortens the working time of the fuel engine relative to each guarantee operation, thereby increasing the use times and time of the whole engine, prolonging the effective working time of finishing the guarantee operation by one-time oiling, solving the problem of reducing the emission of the fuel engine, simultaneously solving the defect problem inherent to the fact that the energy storage battery discharges too fast and has low efficiency in cold areas and influencing the green development.
Based on the method, when the energy storage type (or fuel oil type) electric airport ground guarantee equipment works, the airport ground guarantee equipment can be driven to finish the abutting running by adopting an energy storage battery (fuel oil type engine) of the equipment for kinetic energy when the airport ground guarantee equipment runs in an airplane abutting mode in an apron operation waiting area. After the operation procedure of the energy storage type electric (or fuel oil type) airport ground guarantee equipment and the aircraft is finished, a power control switch on the energy storage type electric (fuel oil type) airport ground guarantee equipment is converted into a ground apron commercial power supply mode by the equipment in a power supply mode with an energy storage battery (fuel oil type).
