Abstract
The invention discloses an ice melting structure for carbon fiber bridge cable ropes. The ice melting structure comprises a heat conducting plate (1) and a plurality of carbon fiber heating cables (2), wherein the heat conducting plate (1) is positioned under the cable ropes, and is bonded to the bottoms of the cable ropes or fixed to the bottoms of the cable ropes through buckles; the carbon fiber heating cables (2) are arranged and uniformly distributed on the inner side of the heat conducting plate (1). According to the ice melting structure disclosed by the invention, on the premise that conventional bridge cable ropes are not changed, the problem that the cable ropes are frozen to form ice slushes and the formed ice slushes drop in winter is solved; when no ice is formed, the electricity supply to the carbon fiber heating cables can be stopped, so that electric energy is not consumed. According to the ice melting structure disclosed by the invention, the carbon fiber heating cables are used for heating, so that the ice melting structure has the characteristics of being light in mass, rapid in heat generation and high in electrothermal conversion rate, and the efficiency that the electric energy is converted into heat energy can reach 90% or above. The heat conducting plate is mounted, so that the shape of the section of each of original cable ropes becomes a shape with a local protruded bottom from a circle, the effect of converging water and heat can be achieved, heat is focused on an ice slush formation region or a root with the ice slushes, the effect of quickly melting the ice slushes or quickly fusing the ice slushes can be achieved, and thermal losses are reduced.
Description
Technical field
The present invention relates to bridge structure technical field, a kind of carbon fiber bridge cable ice structure being mainly used in cable-stayed bridge cable and suspension bridge suspension cable.
Background technology
Cable-stayed bridge cable and suspension bridge suspension cable bottom are bridge floor, and temperature is relatively low in the winter time, and wind speed is relatively big, and when humidity is bigger, bridge cable easily freezes.Can again freeze in bottom to form ice slush additionally, form water droplet bottom ice-melt on daytime cable, when ice slush increases to a certain degree or cable temperature rises, ice slush fracture of root falls, harm bridge floor pedestrian and vehicle safety.Therefore, eliminating ice slush in time or check ice slush formation bottom cable, becoming problem demanding prompt solution, safety current to bridge floor has great importance.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, it is provided that a kind of carbon fiber bridge cable ice structure.
Design principle of the present invention is: the present invention is to set heat-conducting plate on the periphery wall of existing highway bridge cable to be wrapped up by carbon fiber heating cable, cable is heated, just can be by sensing system or according to weather forecast during use, it is energized to carbon fiber heating cable under ice-formation condition, it just automatically generates heat and is conducted to heat-conducting plate, maintain the steady temperature of heat-conducting plate outer surface, reach the effect of automatic snow-melting ice.
One carbon fiber bridge cable ice structure of the present invention, including heat-conducting plate 1 and carbon fiber heating cable 2, described heat-conducting plate 1 is positioned at below cable, and heat-conducting plate 1 is fixed with cable bottom adhesive or employing latch closure；Arrange inside heat-conducting plate 1 and be evenly equipped with many carbon fiber heating cables 2.
Described heat-conducting plate 1 is U-board or V shaped slab, and cable is close at heat-conducting plate 1 two ends.
Described heat-conducting plate 1 is the flexible metal sheet with good heat conductive performance and ductility.
The power of described carbon fiber heating cable 2 is constant, and the length direction of carbon fiber heating cable 2 is axial consistent with bridge cable.
The outer surface of described heat-conducting plate 1 is evenly equipped with salient point 6, is used for guiding ice slush to be formed or ice-melt water row leads.
Compared with prior art, the beneficial effects of the present invention is:
1, the present invention can solve the cable formation ice slush that freezes in the winter time on the premise of being changed without existing highway bridge cable and falls problem；
2, when being formed without ice, the power supply to its carbon fiber heating cable can be stopped, electric energy is not lost；
3, using carbon fiber heating cable to heat due to the present invention, have light weight, the feature fast, electric heating conversion ratio is high of generating heat, electric energy is converted into the efficiency of heat energy can reach more than 90%；
4, original cable cross sectional shape is made to be become bottom local crowning from circle due to the installation of heat-conducting plate of the present invention, thus play convergence moisture and the effect of heat, make heating concentrate on ice slush and form region or existing ice slush root, play fast melt or fusing ice slush effect, reduce thermal losses.
