Abstract

The invention provides a facility for removing snow on roads and airports by solar energy and wind energy. The supporting facility is energy-saving, environment-friendly, corrosion-free and convenient, is important in the traffic innovation and plays an important role in the improvement of roads, streets and aviation security. The facility can convert the solar energy and the wind energy into electric energy and convert the electric energy into the heat energy which is stored underground; the underground rock and earth and the roadbed have the functions of storing heat and transporting heat medium, thereby ensuring that the road surface in the winter keeps an appropriate temperature and that the snow on the road surface melts into water in real time and is discharged from a gutter on the road side; when the rain or snow stops, the road surface is rapid to become dry, thereby reducing the aviation road surface accidents. A photovoltaic system and a wind-electricity system can be selected for one according to the local photo and wind resources or form a photo-wind complementary system, or is parallel in the local state grid. In the latter event, the trough electricity can be adopted to produce heat. A solar battery and the power of the wind power generation are mainly used for the power supply; the power for removing snow is not great; moreover, the solar battery and the power of the wind power generation are only used in sleet in the winter.

Description

Ice and snow removal facilities by solar energy and wind energy at highroad and airport

The invention belongs to solar wind-energy and utilize technology, is the deicing method on highway, street and airport.

Ice and snow exists the safety of traffic and unimpeded threat from ancient times.For many years, the way that people tackle it is mainly salting and black powder, impels its thawing and increases frictional force.Also have cleaning in time to transport in addition.In recent years because the sharp increase on vehicle, speedway and airport prevents that the problem of ice and snow harm from especially seeming important.Salting and powder all influence clean environment.Salt is contaminated soil and underground water also, and metal is produced corrosion, and plant is played ill-effect.Seek free from environmental pollutionly fully, the removing road surface of implementing easily and the method for airport ice and snow are pressing for of Modern Traffic again.The present invention melts ice and snow with thermal methods in real time, and icy water is drained by road surface and side drain gravity flow, and draining also works to remove road dust and fine earth.The thermal source that thaws ice and snow is transformed by electric energy and produces, and electric energy is then produced by solar energy, wind energy.Can be realized the conversion of light-electricity and wind-electricity by these two kinds of regenerative resources in the locality in normal conditions, electricity is converted into heat energy in the locality again, stores in underground.At this moment electric energy does not need the long distance transmission, and therefore, this deicing method is simple and easy and reliable, low cost.

Deicing in temperate zone and frigid zone and other extremely frigid zones be necessary that just and often be limited to winter, individual cases appear at the Qiu Mo or the early spring, the date of actual needs electric energy deicing is few, power demand is little.Build photovoltaic generating system or wind energy turbine set, or build wind, light complementary power generation system, decide on local solar energy resources and wind energy resources, and preferably can be incorporated into the power networks, and deicing is the attachment of a task of indivedual periods of this net with national grid.When underground heat storage increases ground temperature except that ground ice and snow, also can only utilize low ebb.Therefore, the required special investment of this deicing is few, only needs electricity-Re conversion facility.Electricity-Re conversion facility is the special steel pipe that buries under the highway foundation of center, and it extends along the highway axis, and length can reach several km, and there is branched pipe at two ends, can connect power supply.The flow through electric current of special steel pipe changes electric energy into heat energy under the effect of this pipe.This pipe institute heat production can be heated rock heating on every side with highway foundation.Therefore, highway pavement has the temperature more than tens degrees centigrade, and this temperature is enough to make ice dissolution, melts the icy water that forms flows to the roadside along the gradient (20%) on road surface gutter.When snowfall, when rain stops, the road surface can very fast drying.Because rock and highway foundation are the non-conductor of heat, their heat capacity very big again (be air 4000 times) is so when their temperature is elevated to more than 100 ℃, even have a power failure (not heat production) for the moment, the heat of storing also is enough to keep surface temperature more than tens degree, keeps several days.So, can be with the low ebb electricity at underground heat storage, for the whole day usefulness that thaws ice and snow.Above special steel pipe, thermoelectric corner is installed, the temperature on basis, monitoring metal pipe top.When its temperature during near the deformation temperature of flexible pavement, the metal arm can be by air pump for an amount of cold air to the specialty metal pipe, pipe cooling for this reason no longer heats up surface temperature and (exempts from the flexible pavement distortion.To the rigid pavement, temperature upper limit can improve).

Figure of description is the cross section of highway.Wherein 1 is special steel pipe, and 2 is thermoelectric corner, and 3 is the metal arm, and 4 are gutter on both sides of the road.Special steel pipe (amplify among the figure and draw) is embedded under the highway foundation.Thermoelectric corner is installed among the basal layer.The metal arm connects an end of special steel pipe, and the center is guided into outside the road by road.Wherein the temperature that records according to thermoelectric corner of the metal tube of an end is given special steel pipe by an amount of cooling air of air pump (its required electric energy is also supplied with by photoelectricity or wind-powered electricity generation), and control basal layer temperature is not higher than the surface deformation temperature.Then will flow through in the special steel pipe hot air of (heating back) of the arm of the other end flows out, and this hot air can be supplied with highway building along the line and greenhouse heating, also can make the thermal source of low temperature drying technology.Arm 3 still is the prap of power supply, so their terminal is answered exposure ground, and insulation.20% is road gradient on the cross section among the figure, and arrow shows aspect (the icy water flow direction).

In the abundant area of wind energy, can (2 position among the figure) establish wind-driven generator in the highway center, form from the anti-ice and snow system of net heat supply.

When the present invention was used for the airport deicing, the position of special steel pipe was in the middle of taxiway, and just arm should be very long, reach beyond the airport; If with wind energy or solar energy, then wind-driven generator and solar cell all should be arranged in outside the airport, in order to avoid influence flight safety.

The present invention also is applicable to existing highway, street and airport, at this moment both can special steel pipe be embedded in according to aforesaid way underground, can also the forceful electric power light source irradiation ground, make ice dissolution.

The present invention is that details can be consulted this patent of invention based on " electricity of light-electricity and wind-electricity-Re conversion in parallel storage and continuous constant temperature utilization altogether " technology.
