Abstract
The invention discloses an anti-freezing device for a road surface, which comprises an electric heating device arranged in the road surface and piezoelectric ceramics arranged between a roadbed and the road surface. The output ends of the left side and the right side of the piezoelectric ceramics are electrically connected with the electric heating device through a left lead and a right lead, a temperature contact switch is arranged on the right lead, the temperature contact switch is closed when the temperature is lower than zero DEG C, and the temperature contact switch is opened when the temperature is higher than zero DEG C. When an automobile runs on a road, the weight of the automobile presses on the piezoelectric ceramics through the road surface, and voltage is generated on the left side and the right side of the piezoelectric ceramics. When the temperature is lower than zero DEG C in winter, the temperature contact switch is closed, current flows through the electric heating device, the road surface is heated by the electric heating device, the temperature rises, and ice and snow on the road surface melt, therefore an anti-freezing effect is achieved. When the temperature is higher than zero DEG C, the temperature contact switch is opened, and the electric heating device does not work.
Description
Technical field
The present invention relates to defroster, especially a kind of highway pavement is prevented freezing device.
Background technology
When highway pavement froze in freezing day, can make the automobilism difficulty, accidents caused, the serious threat personal safety at present, prevents that the method that highway pavement freezes from mainly being that manual work is rooted out, and efficient is low, and labour intensity is big.
Summary of the invention
The objective of the invention is to: provide a kind of highway pavement simple in structure, reasonable in design, applied widely to prevent freezing device.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
A kind of highway pavement of the present invention is prevented freezing device; It comprises the electrothermal device that is arranged in the highway pavement; And being arranged at the piezoelectric ceramics between roadbed and the said highway pavement, the output of the said piezoelectric ceramics left and right sides is electrically connected with said electrothermal device through left side lead, right side lead respectively, on the lead of said right side, is provided with the temperature contact switch; Said temperature contact switch is closed when temperature is lower than zero degree, when temperature is higher than zero degree, breaks off.
Said piezoelectric ceramics is the stacked formation of multilayer piezoelectric ceramic, and each lamination electroceramics is connected in series.
Compared with prior art the invention has the beneficial effects as follows: owing to adopt technique scheme, piezoelectric ceramics, left side lead, electrothermal device, right side lead and temperature contact switch constitute the electrical heating loop, when on the highway automobilism being arranged; The weight of automobile is pressed on the piezoelectric ceramics through highway pavement, produces voltage in the left and right sides of piezoelectric ceramics, when winter temperature is lower than zero degree; Said temperature contact switch is closed; Electric current flows through electrothermal device, and highway pavement is heated by electrothermal device, and temperature rises; Melt the ice and snow on the highway pavement, thereby reach anti-freeze effect.When the same day, the temperature degree was higher than zero degree, the temperature contact switch broke off, and electrothermal device is inoperative.This highway pavement simple in structure, reasonable in design, applied widely is prevented freezing device, can effectively solve the technical problem that the on business freezing vehicle operating that causes in road is difficult, have accident potential.
In order to improve electric pressure, said piezoelectric ceramics is the stacked formation of multilayer piezoelectric ceramic, and each lamination electroceramics is connected in series.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of highway pavement of the present invention is prevented freezing device, and it comprises the electrothermal device 6 that is arranged in the highway pavement 1, and is arranged at the piezoelectric ceramics 3 between roadbed 4 and the said highway pavement 1.Said piezoelectric ceramics 3 is the stacked formation of multilayer piezoelectric ceramic; Each lamination electroceramics is connected in series; The output of its left and right sides is electrically connected with said electrothermal device 6 through left side lead 2, right side lead 2 ' respectively; On said right side lead 2 ', be provided with temperature contact switch 5, said temperature contact switch 5 is closed when temperature is lower than zero degree, when temperature is higher than zero degree, breaks off.
When practical application, the anti-freezing device of a plurality of said highway pavements is distributed in the whole piece highway, when on the highway automobilism being arranged; The weight of automobile is pressed on the piezoelectric ceramics through highway pavement, produces voltage in the left and right sides of piezoelectric ceramics, when winter temperature is lower than zero degree; Said temperature contact switch is closed, and electric current flows through electrothermal device, and highway pavement is heated by electrothermal device; Temperature rises, and melts the ice and snow on the highway pavement, thereby reaches anti-freeze effect.When the same day, the temperature degree was higher than zero degree, the temperature contact switch broke off, and electrothermal device is inoperative.
