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
The present invention relates to deicer technical field, be specifically related to a kind of military airfield road surface deicing device.
Background technology
Military airfield is the daily workout of air force and the basic guarantee of fighting wartime.The snowfall meeting in winter causes airport pavement accumulated snow to freeze, if removed not in time, can cause aircraft normally to take off and to land, and directly affects daily workout and fight capability, even causes aircraft accident.Therefore, airport deicing is an important process that ensures aircraft Normal Take-Off And Landing under low temperature environment.The research of de-icing work is all paid special attention in countries in the world.Up to now, developed a series of deicing technology.As: according to operation mechanism difference, can be divided into physics, chemistry and mechanical deicing's method etc.
Physics deicing method is directly to heat and make accumulated ice melt to realize the object of deicing to the ice sheet that condenses in Airport Surface, mainly comprises: the modes such as electrical heating, heating using microwave, LASER HEATING, infrared heating.The shortcomings such as the method principle is simple, and development early, but exists efficiency low, and energy consumption is large, and the ice that is melted into water can again freeze under the lower environment of temperature, affects the effect of deicing.
Chemistry deicing method is by the appropriate antifreezing agent of road surface spreading or Snow Agent, as salt (NaCl, CaCl2) or other New Kind of Solvent of Snow-melted, ice and snow on road surfaces melted, and can avoid melting rear ice and snow and again condense.But when in fact Snow Agent, snowfall higher at temperature is little, effect is more obvious; When temperature is lower, snowfall is when larger, poor effect.On the other hand, most of Snow Agent corrosivity is stronger, as sodium salt Snow Agent, easily causes the surface peeling of cement concrete pavement, makes pavement quality impaired and reduction of service life.And almost do not have corrosion-damaged organic Snow Agent cost too high, be unfavorable for applying.
Mechanical deicing's method is to directly act on ice and snow by mechanical device, the sweep-out method that ice and snow is separated with road surface.By the mode of action can be divided into vibrating type, quiet roll split formula, flexible chain impact type, shovel is cut the type such as formula, high-pressure water jet.These class methods to a large amount of accumulated snow, accumulated ice elimination efficiency is high, cost is low, pollution-free, be widely used in the occasion that ice and snow amount is larger.But this class methods Ex-all rate is lower, as for avoiding damaging road surface, forklift etc. often can only be removed the accumulated ice from more than road surface certain altitude, and the remaining accumulated ice relatively thin with the compact one deck in road surface removed very difficult.
In sum, all there is deficiency in various degree in existing airport de-icing method, in the urgent need to a kind of can be efficiently, environmental protection, remove economically the new method of airport pavement accumulated ice.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, efficiently convenient, and is particularly suitable for the road surface deicing device that military airfield uses.
For solving above technical problem, technical scheme of the present invention is: a kind of military airfield road surface deicing device, is characterized in that: comprise ice layer thickness sensor, preamplifier, signal receiver, cyclelog, supersonic generator, power amplifier, actuator;
Described ice layer thickness sensor is arranged on airport pavement, for surveying the icing degree on road surface, and sends ice layer thickness signal; Ice layer thickness sensor is connected to preamplifier by cable, preamplifier is connected to signal receiver by cable, signal receiver is connected to cyclelog by cable, described ice layer thickness signal amplifies, filters through preamplifier, then after signal receiver converts the signal of telecommunication to, is transferred to cyclelog; Cyclelog sends suitable frequency and the ultrasonic wave of waveform according to ice layer thickness signal instruction supersonic generator, and after amplifying, power amplifier is transferred to actuator, described actuator is arranged on airport pavement inside, ultrasonic electrical signal can be changed into mechanical oscillation, finally drive road surface generation oscillation crosswise to reach the object of deicing.
Described actuator is piezoelectric ceramic transducer.
Two surfaces up and down of described actuator are connected with power supply.
Above-mentioned actuator is arranged in parallel at length direction in inside, ground.
Between described actuator, distance is the odd-multiple of Rayleigh ripple half-wavelength.
Described actuator is 10-12mm apart from the distance on military airfield earth's surface.
Described actuator is rectangular strip or discoid.
The present invention utilizes ultrasonic wave to produce instantaneous local high power density to overcome the adhesion on ice sheet and road surface, first by ice sheet and stripping, and then clean and can complete de-icing work with common clearing apparatus, compared with heating, machinery, how much deicing modes, have the advantages that energy consumption is low, pollution-free, efficiency is high, and use ground not damaged for a long time, the military airfield deicing that is therefore particularly suitable for scrambling is used.

Structural representation when Fig. 2 is the use of military airfield road surface deicing device;
Fig. 3 is the layout schematic diagram of actuator in road surface in military airfield road surface deicing device.
The specific embodiment
Below in conjunction with accompanying drawing 1-3 and the specific embodiment, the present invention is further detailed explanation.
When having on military airfield road surface 1 after ice sheet 2, first ice layer thickness sensor 3 detects information icy on road, and send ice layer thickness signal, ice layer thickness signal through preamplifier 4 amplify and filtering after be delivered to signal receiver 5 and change into the signal of telecommunication that controller 6 can be identified, controller 6 judges icing intensity according to ice layer thickness, supersonic generator 7 is sent to instruction, instruction supersonic generator 7 sends the ultrasonic wave of CF and waveform to reach optimum deicing effect, the needed optimum ultrasonic wave waveform of different ice layer thickness and frequency can draw through experiment or analysis in advance.The ultrasonic wave that supersonic generator 7 sends carries out power amplification through power amplifier 8 and acts on actuator 9, actuator 9 is piezoelectric ceramic transducers, after ultrasonic electrical signal excitation, can produce horizontal mechanical oscillation, because actuator 9 is that potting is in airport pavement inside, so road surface can produce oscillation crosswise along with actuator 9, so just on the bonding surface of road surface 1 and ice sheet 2, produce cross shear, in the time that it exceedes the adhesion on ice sheet 2 and road surface 1, ice sheet 2 is peeled off from road surface 1, reaches deicing object.
