Description

Technical Field:

[0001] The utility model relates to a cleaning device for embedded lights on airport runways, belonging to the civil aviation field. Background Art:

[0002] When an airplane lands, sometimes the wheels may press on the embedded lights. The friction between the airplane tires and the navigation lights will leave tire marks on the surface of the navigation lights. These marks are very difficult to clean. Secondly, the navigation lights are installed outdoors, and there are many pollution sources. The pollutants attached to the surface of the navigation lights will affect the illuminance, light intensity and other properties of the navigation lights. The navigation lights have strict requirements for illuminance, light intensity and other properties. The unqualified illuminance, light intensity and other properties will lead to the unqualified of the entire visual navigation lighting system, affecting the normal takeoff and landing of the airplane. At present, the cleaning methods for navigation lights in China often use cleaning agents or wiping with rags. The main defects include: the cleaning efficiency of the navigation lights is very low, the cleaning degree is uncontrollable, and the labor cost is very high, occupying a long time on the airport road surface and environmental protection issues; it is very difficult to clean the stains attached to the lights, and the cleaning agent has a corrosive effect on the surface of the lights.

A steam solenoid valve 113 is arranged on the telescopic pipe between the nozzle of the steam spray pipe 16 and the steam quick connector 111. The cleaning switch 112, the steam solenoid valve 113, the electric telescopic rod 13, and the brush motor 14 are all electrically connected to the aviation connector 112. The controller 3 is electrically connected to the aviation connector 112 through a wire 8. A handle 9 is arranged on the top of the cleaning head.

[0020] Working description: The staff holds the handle 9 and places the cleaning head 1 above the embedded light, so that the cleaning cover 6 covers the embedded light, and places the fixing bolt of the embedded light into the alignment notch 61 to align the brush head of the brush 15 with the lamp socket of the embedded light.

[0021] As Figure 4As shown, the cleaning switch 112 is connected in series with the coils of the intermediate relay KM1, the time relay KT1, and the normally closed contact of the time relay KT5 in the control circuit of the controller 3.

After reaching the time set by the time relay KT1, the electric telescopic rod 14 is just fully extended. At the same time, the brush motor 14 works, driving the brush 15 to rotate forward and reverse intermittently, brushing the lamp socket of the embedded lamp. During the operation of the brush motor 14, the steam solenoid valve 113 and the cleaning agent solenoid valve 115 open and close intermittently at regular intervals; the opening and closing of the steam solenoid valve 113 control the steam generated by the steam generator 4 to be ejected from the steam nozzle 16 towards the nozzle below the brush 15 through the pipeline 7 and the steam quick connector 111, spraying the steam on the lamp socket of the embedded lamp, facilitating the removal of stains on the lamp socket of the embedded lamp by the brush 15; the opening and closing of the cleaning agent solenoid valve 115 control the foam generated in the foam pot 17 to be ejected from the cleaning agent nozzle 18 towards the nozzle below the brush 15 through the cleaning agent quick connector 114, spraying the foam on the lamp socket of the embedded lamp, facilitating the removal of stains on the lamp socket of the embedded lamp by the brush 15; the steam solenoid valve 113 and the cleaning agent solenoid valve 115 open and close intermittently at regular intervals, realizing that when the controller 3 controls the cleaning agent solenoid valve 115 to open, the steam solenoid valve 113 closes, that is, the cleaning agent solenoid valve 115 and the steam solenoid valve 113 are interlocked with each other to prevent the foam sprayed on the lamp socket of the embedded lamp from being blown away by the steam; after the cleaning time reaches the set time in the controller 3, the controller 3 controls the steam solenoid valve 113 and the cleaning agent solenoid valve 115 to close, controls the brush motor 14 to stop working, and controls the electric telescopic rod 13 to retract.
