Abstract
Description
Technical Field
[0001] The utility model belongs to the field of turnout switch machines, and in particular relates to a moisture-proof heating device for turnout switch machines. Background Art
[0002] The switch machine is a very important equipment in rail transit. Its main function is to switch and lock switches, which can greatly improve the marshaling efficiency of freight and passenger vehicles. It can quickly switch the switch to the specified position according to the system control requirements, and keep the switch point rail and the base rail in close contact, ensuring that the vehicle passes through the switch safely and reliably.
[0003] The climate in different regions of my country is different, and the switch machine inevitably works under some harsh environmental conditions. Many factors will affect its normal operation, such as large temperature difference between day and night, excessive or insufficient air humidity, low ambient temperature, etc. These factors will cause the switch machine that can work normally under laboratory conditions to fail to guarantee the stability of its performance in actual use scenarios. The switch machine completes the pulling in and pushing out of the push rod under the action of hydraulic oil, which will push humid air into the equipment cavity. When the ambient temperature drops at night, these humid air will liquefy into small droplets or condense into frost. These small droplets or frost adhere to the parts inside the switch machine, which will cause aging of plastic contact points and corrosion of metal contact points, and will also cause the terminal block to mold. These will cause line failures and pose great safety hazards to the safe operation of the railway.
[0004] Based on the above reasons, the moisture-proof problem inside the switch machine is particularly important. At present, the industry uses absorbent sponges for moisture-proofing, but the moisture-proof effect is not ideal, and the sponge needs to be replaced frequently, and the maintenance operation is cumbersome. Therefore, a more permanent and effective method is needed for moisture-proofing of the switch machine. Utility Model Content

DETAILED DESCRIPTION
[0023] like Figure 1-4 As shown, this embodiment is applied to the cover body 3 of the switch machine.
[0024] A solar panel 1 is provided on the outer side 3a of the cover. Specifically, the solar panel 1 adopts a flexible photovoltaic module, including a plurality of flexible photovoltaic cells 1a, and adjacent flexible photovoltaic cells 1a are connected by flexible wires. The solar panel 1 can convert solar energy into electrical energy, does not require a fuel generator for power supply, conforms to the concept of green environmental protection, and has a relatively low cost. When the train is running at high speed, the flying stones can easily break the glass panel, and the splashing of glass due to the breakage may cause secondary damage to personnel and facilities. Therefore, the flexible photovoltaic module used in this embodiment can effectively avoid this problem.
[0025] The cover 3 in this embodiment is rectangular, so the shape of the solar panel 1 is also made into a corresponding rectangle, so that the solar panel 1 is completely covered to the outer side 3a of the cover, and the solar panel 1 is fixed to the cover 3 by bolts provided at four corners. The bolts are very convenient to install and remove, and no modification is required to the installation structure during the installation process, which can reduce the installation cost and improve the installation and removal efficiency. In other embodiments, the cover 3 can also be made into other shapes, such as hexagonal, etc.
[0026] A graphene heating sheet 2 is provided on the inner side 3b of the cover. Specifically, the graphene heating sheet 2 includes a graphene wire, a silicon tube 2a, an aluminum foil and a thermal insulation cotton 2b. The graphene wire is strung in the silicon tube 2a, the silicon tube 2a is laid on the aluminum foil, and the thermal insulation cotton 2b is covered on both sides of the aluminum foil. The silicon tube 2a has a good thermal conductivity, and the graphene wire strung in the silicon tube 2a can transfer heat well, and the silicon tube 2a can also protect the graphene wire. The silicon tube 2a in this embodiment is bent back and forth, and in other embodiments, the silicon tube 2a can also be arranged in other shapes, such as a ring shape arrangement.
[0027] The graphene heating sheet 2 of this embodiment is bonded to the inner side 3b of the cover body by high temperature resistant epoxy resin adhesive, so it is very convenient to install and remove.
[0028] The switch cover 3 is provided with a wire hole 3c, through which the solar panel 1 is connected to the graphene heating sheet 2. In order to prevent water seepage in the wire hole 3c, the present embodiment also uses hot melt adhesive to seal the wire hole 3c after the wire is threaded.
[0029] In this embodiment, a polyurethane thermal insulation pad is provided on the inner side 3e1 of the side wall of the cover body. The polyurethane thermal insulation pad can prevent heat from being lost to the cover body 3, while maintaining the temperature of the cover body 3 and its vicinity, preventing cold air from condensing on the cover body 3 and its vicinity, and effectively preventing cold air from condensing into water droplets above the switch machine and dripping downward into the electrical equipment below, causing damage to the electrical components.
[0030] The utility model can generate energy, store energy and provide heat by itself without being connected to an external power source. All parts of the utility model are integrated with the cover body 3, and can be directly modified on the existing switch machine. When repairing and replacing, the cover body 3 can even be directly replaced, which is very convenient.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
