[0002] In recent years, with the rapid economic growth and rapid urbanization in my country, the rail transit industry in various cities in China has also developed rapidly. The adaptability of rail transit vehicles to different regions or climates has also attracted attention from all parties. Due to the openness and complexity of the external structure of rail vehicles, there is currently no effective and reliable way for vehicles to cope with extreme cold or snowy weather. When problems occur, they can only be de-iced manually, which is inefficient, unsafe and unreliable. Urban rail transit vehicles are the most convenient way to commute in the city, and they have a very large passenger flow, especially in bad weather. For urban rail vehicles in special areas, heating and de-icing devices are arranged. When the device is working, it can effectively remove the ice produced in extreme cold or snowy weather to ensure the working temperature of equipment in the area.

[0003] For example, the linear guide rail heating device and the front cover opening and closing mechanism using the device disclosed in the utility model with authorization announcement number CN203844757U effectively solve the problem of the high cold climate affecting the function of the opening and closing mechanism, while not causing loss of strength and movement accuracy of the overall structure, so that the front cover opening and closing mechanism can be left stationary for more than 12 hours after the ambient temperature reaches -40°C and still achieve normal opening and closing functions, thereby improving the safety factor of normal operation.

[0004] This prior art also has the following problems when in use: the open structure outside the vehicle is prone to ice formation, manual deicing is difficult to implement, and the workload is large. For this reason, we propose a hidden heating deicing installation structure suitable for subway vehicles. Utility Model Content

The cable trough body on which the heating belt is installed in the installation structure is reasonably arranged along the length direction of the vehicle. The heating belt is located on both sides of the cable trough body. The cable trough body is integrated with the C-shaped trough, and there is no need to design a separate installation structure. The concealment is good and does not increase the complexity of vehicle design, nor does it affect the normal installation of the trough body itself. Heat is conducted through the cable trough body and the cable trough cover, which basically covers most areas under the vehicle, and can remove surrounding ice in extremely cold weather.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a hidden heating and deicing installation structure suitable for subway vehicles, including a wire trough body, the installation structure is composed of a wire trough body, a wire trough cover, a parallel heating belt group, a loop heating power line, and a C-shaped groove. The wire trough body of the installation structure is installed along the length of the vehicle, and the C-shaped groove is located on both sides of the wire trough body. A parallel heating belt group is installed on the inner side of the C-shaped groove, and a loop heating power line is installed on one side of the parallel heating belt group. The parallel heating belt group and the loop heating power line are inserted into the inner side of the C-shaped groove from the end face of the wire trough body and fixed on the inner side of the C-shaped groove. The parallel heating belt group is composed of multiple groups of heating belts, and each group of heating belts is connected to the loop heating power line from a power branch line.

[0007] As a preferred technical solution of the utility model, a threaded hole is opened on the inner wall of the bottom end of the wire trough body, a U-shaped mounting frame is installed on the inner side of the wire trough body, and reserved mounting holes are opened on the bottom surface and both side surfaces of the U-shaped mounting frame.

[0009] As a preferred technical solution of the utility model, round holes are provided at the four corners of the wire trough cover plate, and thread grooves are evenly provided on the top surface of the U-shaped mounting frame.

[0010] As a preferred technical solution of the present utility model, the wire trough body and the C-shaped trough are integrated as a whole, and the wire trough body and the wire trough cover are both made of aluminum alloy metal.

[0011] As a preferred technical solution of the utility model, the surface of the wire trough cover plate is provided with crisscrossing air holes.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] 1. The main body of the cable duct installed in the heating belt of this installation structure is reasonably arranged along the length of the vehicle. The heating belt is located on both sides of the main body of the cable duct. The main body of the cable duct is integrated with the C-shaped duct. There is no need to design a separate installation structure. It has good concealment and does not increase the complexity of vehicle design. It will not affect the normal installation of the duct itself.
