Description
Technical field
The invention belongs to the heat pump utilization, be specifically related to a kind of heat pump snow melt technology.
Background technology
The problems that winter, snow back accumulated snow covered on the road surface to be brought have become the multinational thorny difficult problem in the world, in order to ensure traffic safety and unobstructed need in time remove the snow.Snow-removing method commonly used at present has: Snow Agent is spread on the road surface; Special-purpose machinery is rooted out the back transportation; The hot snow melt of boiler loaded on truck and adopt hot snow melt of underground buried tube or the like at special road section.Though these methods are effective, also bring a series of problems simultaneously, can cause secondary environmental pollution as Snow Agent; It is that a large amount of accumulated snow need be deposited or transportation in time in addition that power shovel removes the problem of bringing; Boiler loaded on truck cost of investment height, the big efficient of energy consumption is lower; The hot snow melt of underground buried tube is energy-conservation, but initial outlay is huge and be only applicable to special highway section, as place among a small circle such as charge station, sloping road.Therefore above-mentioned technology or method are not the preferred plan that solves pavement snow melting, and proposition of the present invention can be drawn the advantage of above-mentioned technology, and bad problem is well solved.
Summary of the invention
The objective of the invention is to utilize heat pump techniques, draw heat in the external environment and improve its temperature through heat pump and be used for hot snow melt, a kind of efficient height that removes the snow, heat pump type snow melting vehicle that cost is low are provided.
Know-why of the present invention is: heat pump type snow melting vehicle is made up of dynamical system, heat pump and three parts of snow-melting system, and dynamical system comprises: motor, battery, cooling heat exchanger, clutch and auxiliary cooling heat exchanger etc.; Heat pump comprises: compressor, condenser, electric expansion valve, evaporimeter etc.; Snow-melting system comprises: U type feeder, conveyer belt, water storage box, conveyer belt driving shaft, take off snow runner etc.Dynamical system places front portion, snow melting vehicle chassis; Heat pump places middle part, snow melting vehicle chassis; Snow-melting system places rear portion, snow melting vehicle chassis.Key problem in technology of the present invention is: motor and heat pump profit are combined as a whole, with the power source of motor as heat pump, evaporimeter in the heat pump is draw heat from the water tank of cooled engine and surrounding environment, discharge by condenser, and condenser is combined closely with the snow melt section, so consumed energy only is compressor and relevant ancillary service energy consumption in the cyclic process.The heat of high temperature that heat pump is used for snow melt equals to compare with the electrical heating snow melt with boiler from low-temperature heat source draw heat and compressor consumed energy sum, and the accumulated snow that obviously consumes identical energy thawing is more.Another key of the present invention is: the collection of snow and the thawing of snow.Collection as accumulated snow is divided into two kinds of structures, and first kind of form is: a U type collection snow groove is tilted to place the car body middle part, and along with the reach of locomotive, the profile of tooth snow cave shovel of collection snow front of the slot is sent snow into collection snow groove.Because the bottom of U type collection snow groove is a conveyer belt, therefore conveyer belt constantly sends into accumulated snow the upper end water storage box by the upper and lower end drive shaft.In order to make accumulated snow can enter the snow melt passage smoothly, above the top of U type collection snow groove, be provided with and take off the snow runner.Because the bottom of condenser upper surface and snow melt passage is closely as one, so the heat that condenser gives out makes the snow melt passage keep certain high temperature with snow melt.Snow-broth after the thawing is taken advantage of a situation and is entered water storage box; Second kind of form is: be provided with the snow adsorbing pipe road perpendicular to the road surface at the car body middle part, reach along with locomotive, the negative pressure that is produced by car body top air-introduced machine constantly sucks accumulated snow the snow adsorbing pipe road, and its snow melt section is at snow adsorbing pipe road horizontal segment, and air-introduced machine is positioned at inhales the snow channel outlet.Because the engine cool heat exchanger and the upper surface of condenser and the bottom of snow adsorbing pipe road horizontal segment are closely as one, so the heat that engine cool heat exchanger and condenser give out makes snow adsorbing pipe road horizontal segment keep certain high temperature with snow melt, send into the upper end water storage box then.During second kind of form structure is applicable to and snows or do not have through the accumulated snow that rolled.For fear of snow melting vehicle snowflake congestion affects heat exchange during operation during snowing, wire gauze is housed and can regularly brushes snow in the evaporimeter outside.Be equipped with netted baffle plate at snow adsorbing pipe road horizontal segment and convex tank top, wherein the baffle plate of establishing in the horizontal segment is to prevent that in a large number the snow covers of thawing are not taken away, and the baffle plate in the convex tank top passage is to stop the moisture content of evaporation in the water storage box and snow cover air-introduced machine extraction on a small quantity.
