Device and method for preserving heat and de-icing bridge floor

Abstract

The invention discloses a device for preserving heat and de-icing a bridge floor. The device comprises a variable frequency fluid heating device, and radiating pipelines paved below the bridge floor; the variable frequency fluid heating device communicates with the radiating pipelines; the variable frequency fluid heating device and the radiating pipelines are filled with fluid; the fluid circularly flows between the variable frequency fluid heating device and the radiating pipelines. The invention further discloses a method for preserving heat and de-icing the bridge floor. With the adoption of the device and the method, the bridge floor and a bridge can be heated without pollution and corrosion; meanwhile, a comfortable living environment is provided to wild birds inhabiting in clearances of a bridge frame structure in winter, the temperature of the bridge floor can be raised by the body temperature of the wild birds, and thus, the ice and snow can be removed in real time; a plurality of functions such as energy saving, environment protecting, and wild birds protecting can be achieved.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a bridge deck warm-keeping and ice-melting equipment and a bridge deck warm-keeping and ice-melting method. Background technique [0002] According to the statistics of the traffic department, the incidence of traffic accidents on ice and snow roads is 6 to 8 times that of usual times, which causes huge economic losses every year. The traditional artificial snow removal methods can no longer meet the increasing demands of highways and roads. How to quickly, economically and scientifically remove ice and snow from cities and highways has become a difficult problem to ensure the smooth flow of northern roads and highways in winter. [0003] Bridge decks and culvert roads are prone to freezing. Because the temperature difference between the upper and lower sides of bridges and culverts is large, the moisture in the air is more likely to condense. If the bridge an...

Problems solved by technology

The snow removal effect on icy roads is more obvious, but the disadvantage is: high cost

Environmentally friendly deicing agents have little impact on the environment, but the quality is unstable and the cost is higher

[0006] At present, chlorine salt deicing agents are often used in my country to remove snow and ice. This method not only seriously corrodes the bridge structure, but also increases maintenance costs in the later period and seriously reduces the service life of the bridge. Moreover, the environment on both sides of the road is destroyed, and the vegetation dies. The water is polluted, so what kind of ice and snow removal plan should be adopted to achieve advanced and environmental protection without causing corrosion to the existing road and bridge structures is an urgent problem to be solved at present

[0007] At the same time, due to the heat island effect generated by the city, the urban area is warmer than the suburbs, which attracts groups of crows and other birds to live in, which brings noise, feces pollution and disease transmission risks to the city. Although the citizens have invested a lot Manpower and material resources are used to clear the bird's nest, but the bird has no bird's nest. It lives on the low-voltage overhead line at night, relying on a little temperature generated by the current on the wire to supplement its body temperature. It can still survive and cannot be driven away. Only in the daytime do the birds fly in groups Forage to Suburban Junkyards

[0008] Since the low-voltage power transmission and distribution system will generate part of the loss during operation, the heat generated by the outdoor overhead wires has attracted a large number of wild birds that live on domestic garbage dumps in the suburbs of the city; low-voltage power transmission and distribution cables have electromagnetic radiation, which is not conducive to wild birds. Animals survive healthy, and their excrement increases the labor intensity of sanitation workers and roadside parking owners
