Abstract
The utility model relates to an alternating current electrothermal type road-bridge ice-snow cleaning device, which relates to an electrical heating ground surface ice-snow cleaning device of winter roads and bridges for solving the problems that the existing device which unfreezes snow through laying an electrical heating device under ground surface needs to do insulation treatment, has low heat utilization efficiency, and is not easily repaired when one portion is damaged. A plurality of iron dust or carbon fiber powder and asphalt or cement mixture electric heater units are all arranged in an asphalt pavement layer according to a certain distance, and 36V alternating current voltages are arranged on both ends of each iron dust or carbon fiber powder and asphalt or cement mixture electric heater unit. The alternating current electrothermal type road-bridge ice-snow cleaning device is not needed to do insulation treatment, which avoids the problem of earth leakage which is caused by damaging the insulation outsourcing. The alternating current electrothermal type road-bridge ice-snow cleaning device utilizes the heat quantity which is generated when current flow passes through a conductor to melt snow, and the integral pavement which is paved with the alternating current electrothermal type road-bridge ice-snow cleaning device is enabled to achieve the purpose of cleaning ice and snow in short time after snowing. The alternating current electrothermal type road-bridge ice-snow cleaning device has no influence to normal traffic in the process of cleaning ice and snow.
Description
Technical field
The utility model relates to highway and the clear ice and snow device in electrical heating road surface of bridge in a kind of winter.
Background technology
The highway transportation of north of china in winter usually is subjected to the puzzlement of ice and snow, in case snowfall appears in land route supply lines such as highway, bridge, will cause the transportation paralysis if can not in time clear up.The large tracts of land snowfall of China middle part has brought great difficulty to transportation at the beginning of 2008, because middle part winter temperature characteristics, sleet and snow drop to the evaporation that also is not able to do in time on the ground and have just formed ice, make speedway and bridge have to seal completely, and the method for snow clearing machinery that northern area generally uses and snow-melting agent all can't be removed a large amount of ice and snow at short notice, also can influence the normal operation of traffic in clear ice and snow process.Publication number be 2816127 name be called full-automatic clear ice and snow system utility model patent disclose a kind of by below the road surface, laying the device that electric heater unit melts accumulated snow fast, but this device exist heat utilization ratio lower, need carry out insulation processing, in case appearance partly damages the not shortcoming of easy-maintaining.
The utility model content
The utility model for solve existing by below the road surface, lay needs that device that electric heater unit melts accumulated snow exists carry out insulation processing, heat utilization ratio lower, damage the not problem of easy-maintaining in case part occurs, provide a kind of alternating current hot type bridge clear ice and snow device.The utility model is made up of with pitch or cement mixing body electric heater unit 1 a plurality of iron powders or carbon fiber powder, a plurality of iron powders or carbon fiber powder and pitch or cement mixing body electric heater unit 1 all are set in parallel in the blacktop at a certain distance, add the alternating voltage of 36V at the two ends of each iron powder or carbon fiber powder and pitch or cement mixing body electric heater unit 1.
Beneficial effect: the utility model adopts the low-voltage that directly electric heating sheets is arranged in the blacktop and adds 36V at iron powder or carbon fiber powder and pitch or cement mixing body electric heater unit two ends, so do not need to carry out insulation processing, avoided because of corrosion, extruding etc. easily causes the problem that insulate the outsourcing damage and cause leaking electricity, the utility model utilizes electric current to melt accumulated snow by the heat that conductor produces, and make this whole piece of the present utility model road surface of laying in snowfall finishes the back short time, reach the purpose of ice and snow clearly, in clear ice and snow process, normal traffic is not influenced.
Description of drawings
Fig. 1 is the structural representation that a plurality of iron powders or carbon fiber powder and pitch or cement mixing body electric heater unit 1 are set in parallel in the blacktop at a certain distance.
The specific embodiment
The specific embodiment one: referring to Fig. 1, present embodiment is made up of with pitch or cement mixing body electric heater unit 1 a plurality of iron powders or carbon fiber powder, a plurality of iron powders or carbon fiber powder and pitch or cement mixing body electric heater unit 1 all are set in parallel in the blacktop at a certain distance, all the design width with blacktop is identical for the length of each iron powder or carbon fiber powder and pitch or cement mixing body electric heater unit 1, the ratio that the length and width of each iron powder or carbon fiber powder and pitch or cement mixing body electric heater unit 1 are high is 10～20: 5～8: 1～2, the alternating voltage that adds 36V at the two ends of each iron powder or carbon fiber powder and pitch or cement mixing body electric heater unit 1, the temperature that makes the set blacktop of each electric heating sheets reaches 10～30 ℃ according to the difference of iron powder or carbon fiber powder addition, the accident that the appearance of a plurality of iron powders or carbon fiber powder and pitch or cement mixing body electric heater unit 1 does not have insulation crust can not cause electric leakage to hurt sb.'s feelings yet, and the heat of a plurality of iron powders or carbon fiber powder and pitch or cement mixing body electric heater unit 1 can better be dispersed in the blacktop, snowfall begins the back opening power and gets final product fast snow melting, a snow-broth part of melting can evaporate, another part can enter the drainage system of bridge, to reach the purpose of efficient clear ice and snow.The input of transformer directly is connected with the 10kV high-tension electricity, the output output 36V alternating current of transformer is a plurality of iron powders in parallel or carbon fiber powder and pitch or cement mixing body electric heater unit 1 directly, make and keep bigger current value in the electrical network, can also increase simultaneously the power factor in the electrical network, improve the active power of using electricity system.
Claims (1)
