Abstract
The utility model discloses an electromagnetic turnout snow-melting and ice-melting device, comprising an electromagnetic disc arranged at the bottom of a steel rail and a controller electrically connected with the electromagnetic disc, wherein the controller is also electrically connected with a temperature sensor; and the electromagnetic disc consists of a shell and an electromagnetic coil arranged in the shell. The electromagnetic turnout snow-melting and ice-melting device generates alternating magnetic field by the electromagnetic coil in the electromagnetic disc; a steel rail cuts the alternating magnetic field to generate alternating current at a metal part of the bottom of the steel rail (namely, vortex flow); and the vortex flow leads iron molecules of the steel rail to move irregularly at high speed, and the molecules collide and friction mutually to generate heat energy so as to lead the steel rail to heat by self at high speed. Therefore, a heat source of the electromagnetic turnout snow-melting and ice-melting device is from the bottom of the steel rail instead of conducting heat generated by the self electromagnetic coil to the steel rail, therefore, the heat efficiency is high, the operating cost is low and the snow-melting and ice-melting effects are good.
Description
Technical field
The utility model relates to a kind of snow melt deicing device, particularly a kind of snow melt deicing device that is used for railway switch.
Background technology
In order to guarantee the railway transportation installation, snow melt, deicing device need be installed, on the track switch of rail with the accumulated snow on the removal track switch, icing.At present, the domestic track switch snow melt deicing device of having installed and used at the scene has multiple, the method for basic principle for laying resistance-type electrical heating bar at track switch stock rail waist, generate heat by the electric heating bar, with the heat transferred rail, rail temperature is raise, to reach the purpose of snow melt ice-melt.Because electric heating bar heating mainly is by heat conducting mode, when the electric heating bar is to rail conduction heat, a large amount of heats is dispersed in the air goes, cause heat to waste in a large number, thereby cause operation cost to increase.In addition, the heating of electric heating bar makes the rail temperature rise speed slower, the requirement in the time of can not satisfying cold especially and heavy snow.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, quick heating, cost is low, the snow melt ice-melt is effective electromagnetic type track switch snow melt deicing device.
In order to solve the problems of the technologies described above, the utility model provides a kind of electromagnetic type track switch snow melt deicing device, comprise the electromagnetic disc that is arranged at rail foot, and with the controller that described electromagnetic disc electrically connects, also be electrically connected with temperature pick up on the described controller; Described electromagnetic disc is made of housing and the electromagnetic coil that is arranged in the housing.
Further, described electromagnetic disc is rectangular.
Further, described electromagnetic disc is arranged between the sleeper of rail.
Further, described controller is made up of control circuit, oscillating circuit, temperature signal converter, temperature-control circuit, described temperature pick up is connected with control circuit with temperature-control circuit through described temperature signal converter successively, described electromagnetic disc links to each other with described control circuit by described oscillating circuit, and control circuit connects power supply.
Electromagnetic type track switch snow melt deicing device of the present utility model, produce alternating magnetic field by the electromagnetic coil in its electromagnetic disc, rail cuts this alternating magnetic field and produces the electric current (being eddy current) of alternation at the rail foot metalwork, eddy current makes the random motion of rail iron molecule high speed, molecule runs foul of each other, rubs and produces heat energy, make rail heating at a high speed voluntarily itself, so thermal source of the present utility model comes from rail foot rather than rail is given in electromagnetic coil heating conduction itself, so thermal efficiency height, running cost are low, the snow melt ice-melt is effective.
Description of drawings
Fig. 1 is the structural representation of electromagnetic type track switch snow melt deicing device one Application Example of the present utility model;
Fig. 2 is the schematic diagram in rail cross section, middle electromagnetic disc place embodiment illustrated in fig. 1.
Among the figure: 1. electromagnetic disc, 2. controller, 3. temperature pick up, 4. rail, 5. sleeper.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to qualification of the present utility model.
As shown in Figure 1, see also shown in Figure 2 simultaneously, electromagnetic type track switch snow melt deicing device of the present utility model comprises the electromagnetic disc 1 that is arranged at rail 4 bottoms, and with the controller 2 that described electromagnetic disc 1 electrically connects, also be electrically connected with temperature pick up 3 on the controller 2.Wherein, electromagnetic disc 1 is made of housing and the electromagnetic coil that is arranged in the housing, is located between the sleeper 5 of rail 4.Electromagnetic disc 1 is preferably rectangle, adapts with the shape with rail 4.Temperature pick up 3 is arranged on rail 4 one sides.
Controller 2 is made up of control circuit, oscillating circuit, temperature signal converter, temperature-control circuit, and temperature pick up is connected with control circuit with temperature-control circuit through the temperature signal converter successively, and electromagnetic disc links to each other with described control circuit by oscillating circuit.
Control circuit obtains electric energy by power supply and sends oscillating circuit to, oscillating circuit produces the alternating current of the electromagnetic coil of the electromagnetic disc 1 of flowing through, make electromagnetic disc 1 produce alternating magnetic field, the rail 4 of electromagnetic disc 1 top cuts these alternating magnetic fields and partly produces eddy current in rail 4 bottom metal, eddy current makes rail 4 iron molecule high speed random motions, molecule runs foul of each other, rubs and produces heat energy, and rail 4 itself is generated heat at a high speed voluntarily.
During heating snow melt ice-melt, carry out Artificial Control or control automatically according to weather, temperature and switch section accumulated ice snow situation.Temperature pick up 3 on the rail 4 sends the temperature of rail 4 to control circuit through temperature signal converter and temperature-control circuit, by control circuit control heating power, with the heating-up temperature of further control rail 4.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited thereto.Being equal to that those skilled in the art are done on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
