Example Embodiment

[0020] Attached below Figure 1-3 The present invention will be further described in detail with specific embodiments.

[0021] When an ice layer 2 forms on the road surface 1 of the military airport, the ice layer thickness sensor 3 first detects the icing information on the road surface, and sends out an ice layer thickness signal, which is amplified and filtered by the preamplifier 4 and then transmitted to the signal The receiver 5 converts the electrical signal that can be recognized by the controller 6, and the controller 6 judges the freezing strength according to the thickness of the ice layer, and issues instructions to the ultrasonic generator 7, and instructs the ultrasonic generator 7 to emit ultrasonic waves of a specific frequency and waveform to achieve optimal The deicing effect, the optimal ultrasonic waveform and frequency required for different ice thicknesses can be obtained through experiments or analysis in advance. The ultrasonic wave emitted by the ult...

Abstract

The invention discloses a road surface de-icing device for a military airfield. The road surface de-icing device comprises an ice layer thickness sensor (3), a front-arranged amplifier (4), a signal receiver (5), a program controller (6), an ultrasonic wave generator (7), a power amplifier (8) and an executor (9). Ultrasonic waves are utilized for generating instantaneous local high power density to overcome the adhesive force of an ice layer and the road surface, the ice layer is stripped from the road surface, and then a common cleaning device is used for cleaning, so that the de-icing work is finished. Compared with a heating de-icing mode, a mechanical de-icing mode and a geometrical de-icing mode, the road surface de-icing device has the advantages of being low in energy consumption, free of pollution, high in efficiency and wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of deicing devices, in particular to a road surface deicing device for military airports. Background technique [0002] Military airports are the basic guarantee for the Air Force's daily training and wartime operations. Snowfall in winter will cause the snow on the airport road to freeze. If it is not removed in time, it will cause the aircraft to fail to take off and land normally, directly affect daily training and combat capabilities, and even lead to flight accidents. Therefore, airport deicing is an important task to ensure the normal takeoff and landing of aircraft in low temperature environment. All countries in the world are very concerned about the research of deicing work. So far, a series of deicing technologies have been developed. Such as: According to different operating mechanisms, it can be divided into physical, chemical and mechanical deicing methods. [0003] The physical deicing meth...
