Abstract
The utility model discloses a deicing device for an electrified railway tunnel. The deicing device comprises a housing and a heating element arranged in the housing, as well as a temperature controller and a temperature sensor which are arranged outside the housing and connected with a power supply, wherein the temperature controller is connected with both the heating element and the temperature sensor through lead wires. The deicing device has a reasonable design and a simple structure; as the housing is completely made of an insulating material, the working performance is safe and reliable; manpower is saved; the deicing effect is good; and normal operation and safe power supply of an overhead line system in the electrified railway tunnel are guaranteed.
Description
Technical field
The utility model belongs to the electromechanical equipment technical field, relates to a kind of deicer, is specifically related to a kind of electrified railway tunnels deicer.
Background technology
At northern area, because part electrified railway tunnels top leaks, can form icicle winter at tunnel top or tunnel wall, the contact net live part that is erected in the tunnel partly tends to invading the icicle discharge of its insulation distance, cause disconnected strand of traction substation tripping operation, contact net burn, or directly cause catenary cut off, influence train operation.For this reason, electric railway unit of operation has to spend great amount of manpower and material resources adopt the method deicing of manually beating ice in the winter time, to guarantee electrifing railway supply safety.Nonetheless, because icing rate is fast in the tunnel, cause the event of contact net tripping operation to happen occasionally because freezing.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provide a kind of reasonable in design, simple in structure, service behaviour is safe and reliable, deicing is effective, can guarantee the electrified railway tunnels deicer of contact net safe power supply.
For achieving the above object, the technical solution adopted in the utility model is: the electrified railway tunnels deicer, it is characterized in that: comprise housing and be arranged on the interior heater element of housing, and being arranged on hull outside and the temperature controller that is connected with power supply and temperature pick up, described temperature controller all is connected with temperature pick up with heater element by lead.
Above-mentioned electrified railway tunnels deicer, it is characterized in that: described housing comprises top board, base plate and the gusset of being made by insulation materials, described top board is set in parallel in the top of base plate, and top board is connected by described gusset with base plate, and gusset is provided with for the connector of installing.
Above-mentioned electrified railway tunnels deicer is characterized in that: be provided with warming plate between described heater element and the base plate, the surface of described warming plate is provided with thermal reflecting coating.
Above-mentioned electrified railway tunnels deicer is characterized in that: the cross section of described top board and the cross section of base plate are arc.
Above-mentioned electrified railway tunnels deicer is characterized in that: described heater element is heating tape.
The utility model compared with prior art has the following advantages:
(1) the utility model device is reasonable in design, and is simple in structure, and housing adopts insulation materials, and service behaviour safety, reliable is saved manpower, and deicing is effective, can guarantee the contact net safe power supply;
(2) adopt the permanent power heating cable of two-phase, but that its heating-up temperature scope assurance device itself reaches deicing in the short period of time is temperature required;
(3) adopt two sense intelligent temperature control systems, can play overtemperature protection and reduce the purpose of energy consumption;
(4) the device top board adopts the arc design according to the tunnel, is easy to top ponding and in time flows down from the side.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises housing 1 and the heater element 2 that is arranged in the housing 1, and the temperature controller 3 and the temperature pick up 4 that are arranged on housing 1 outside and are connected with power supply, described temperature controller 3 all is connected with temperature pick up 4 with heater element 2 by lead.
As shown in Figure 2, described housing 1 comprises top board 5, base plate 6 and the gusset of being made by insulation materials 7, and described top board 5 is set in parallel in the top of base plate 6, and top board 5 is connected by described gusset 7 with base plate 6, and gusset 7 is provided with for the connector of installing 10.Be provided with warming plate 8 between described heater element 2 and the base plate 6, the surface of described warming plate 8 is provided with thermal reflecting coating 9.
As shown in Figure 1, the cross section of the cross section of described top board 5 and base plate 6 is arc.
Described heater element 2 is heating tape.
The utility model device has ice-melt and drainage function.When working in the tunnel in the winter time, the housing 1 of device is fixed in tunnel top leakage point below by connector 10, for guarantee this device can be reliably under the situation of net-fault normal power supply, trouble free service, the top board 5 of component devices housing 1, base plate 6 and gusset 7 all adopt insulation and the good epoxide resin materials of heat resistance to make.The heating tape of the housing 1 inner heater element that arranges 2 for being connected with power supply, the working condition of heating tape is by temperature controller 3 controls, and temperature controller 3 is controlled heater switch and heating-up temperature according to the temperature information of temperature pick up 4 tunnel environment that provides and this device top board 5.Cross when low in subzero or this device top board 5 self temperature when the environment temperature in the tunnel, 3 of temperature controllers start heater switch, beginning ice-melt work; When the upper surface of top board 5 reaches a certain setting value, device will stop heating.In non-icing season, this device can play the effect of water conservancy diversion under the no power state, make the infiltration of tunnel upper along the runs down both sides of curved roof 5, away from the contact net electrical body, thereby the contact net in the assurance tunnel can both operate as normal under various seasons, all temps condition, guarantees the power supply safety of contact net.
