The heating device 4 includes a water tank 9 fixedly connected to the upper left end of the ground cleaning vehicle body 1, multiple heating pipes 10 embedded inside the water tank 9, a connecting rod 13 fixedly connected inside the water tank 9, two floats 14 slidably sleeved on the outside of the connecting rod 13, two contact switches 15 embedded on opposite sides of the connecting rod 13, and a water pump 5 fixedly mounted on the upper side of the water tank 9. The cleaning device 6 includes a first connecting plate 16 connected to the right side of the water pump 5, a second connecting plate 17 fixedly connected to the right side of the first connecting plate 16, two electric telescopic rods 18 fixedly mounted to the right side of the second connecting plate 17, a conversion connector 19 fixedly mounted at the output end of the electric telescopic rods 18, and a drain head 20 connected to one side of the conversion connector 19.

[0029] The ground cleaning vehicle body 1 has a pulling structure on its side, which includes two connecting rods 2 fixedly connected to the side of the ground cleaning vehicle body 1 and a tow head 3 fixedly connected to the connecting rods 2 away from the ground cleaning vehicle body 1. An adjustment device 7 is provided on the upper side of the ground cleaning vehicle body 1. The adjustment device 7 includes a first housing 22 fixedly connected to the upper right end of the ground cleaning vehicle body 1, a drive motor 23 fixedly installed on the right side of the first housing 22, a threaded rod 24 fixedly connected to the output end of the drive motor 23, a threaded sleeve 25 threadedly connected to the outside of the threaded rod 24, a second housing 27 fixedly connected to the upper side of the ground cleaning vehicle body 1, a sliding rod 28 fixedly connected inside the second housing 27, and a sliding sleeve 26 slidably sleeved on the outside of the sliding rod 28. A water tank 9 is inlaid on the front end face. A temperature sensor 12 is installed on the right side of the front face of the water tank 9, and a PLC controller 8 is embedded therein. The suction pipe of the water pump 5 passes through the heating device 4 and extends into it. The discharge pipe of the water pump 5 passes through the first connecting plate 16 and extends into the second connecting plate 17. Three alarm lights 11 are embedded on the left side of the water tank 9. The three alarm lights 11 are arranged vertically at equal intervals. Multiple heating tubes 10 are arranged in groups of three, and each group of heating tubes 10 is arranged vertically at equal intervals inside the water tank 9. The output end of the contact switch 15 is electrically connected to the output end of the water pump 5. One side of the first connecting plate 16 is vertically fixedly connected to one side of the threaded sleeve 25. The other side of the first connecting plate 16 is vertically fixedly connected to one side of the sliding sleeve 26. The right side of the second connecting plate 17 is connected to two telescopic drain pipes 21 that are compatible with the conversion connector 19.

[0030] The working principle of the above embodiments is as follows:

[0031] The ground cleaning vehicle body 1 moves to the end of the aero-engine and is connected to the tow head 3 at the end of the connecting rod 2 by rope. The heating tube 10 is controlled by the PLC controller 8 to heat the water inside the water tank 9. The temperature sensor 12 is used to observe the specific water temperature. The electric telescopic rod 18 is driven to extend the conversion joint 19 to extend the drain head 20 to one side. The drive motor 23 controls the threaded sleeve 25 to drive the first connecting plate 16 to adjust the lateral position of the drain head 20 on the upper side of the ground cleaning vehicle body 1. Then, the rope is pulled to rewind and move the ground cleaning vehicle body 1 towards the aero-engine. At this time, the water pump 5 absorbs the water in the water tank 9 and discharges it from the drain head 20 to wash the aero-engine. As the water continues to drop, the float 14 will also separate from the contact switch 15 at the top. When the bottom of the float 14 contacts the contact switch 15 on the lower side, the operation of the water pump 5 will be cut off. At the same time, the alarm light 11 on the left side of the water tank 9 will be turned on to sound an alarm, notifying the staff that the water in the water tank 9 cannot be discharged and that water needs to be replenished in time.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
