[0035] Through the above technical solution:

[0036] The fixed rails 33 are set up on both sides of the railway turnout with a certain distance between them. The structures on both sides are symmetrically arranged. Antifreeze is stored in the water pump box 20. When the railway turnout needs to melt snow, the motor 1 2 and the motor 2 28 are operated first. The motor 1 2 drives the threaded tube 3 to rotate and pushes the support seat 5 to a distance through the screw 4, so that the hollow rod 1 9 slides along the surface of the hollow rod 2 10. The side of the fixed seat 1 is slightly tilted so that the hollow rod 1 9 moves obliquely upward when it slides out. The motor 2 28 drives the hollow shaft 13 to rotate through the gear 29 and the toothed ring 27, so that the power supply line and water pipe wound on the hollow shaft 13 are released, so that the power supply line and water pipe adapt to the extension of the hollow rod 1 9 and the hollow rod 2 10, and keep the same The connection between the nozzle 6 and the hot air blower 7, the battery 23 is rotatably connected to the vertical plate 25 through the support shaft 3 24, and when the hollow shaft 13 rotates, the support shaft 2 16 and the line pipe 22 drive the battery 23 to rotate, so that the power supply line connected to the battery 23 rotates synchronously with the hollow shaft 13 to avoid torsion damage to the power supply line. When the support seat 5 moves to the extreme position, the nozzles of the nozzle 6 and the hot air blower 7 are aimed at the area where the railway switch needs to melt snow. The hot air blower 7 has remote control and hot and cold air switching functions, which is the existing technology. Then the battery 23 is started to power the hot air blower 7. The hot air blower 7 first blows out cold wind to blow away the fine snow particles accumulated at the switch to reduce accumulation. At the same time, the side of the rail car 12 The driving motor is started to move the rail car 12 along the top of the fixed rail 33, so that the cold wind blown by the hot air blower 7 cleans the fine snow particles, and then the rail car 12 moves in the opposite direction and the hot air blower 7 starts to blow out hot air to melt the snow at the switch. The rail car 12 moves to the initial position and then moves in the opposite direction again. At this time, the battery 23 and the hot air blower 7 are turned off, and the water pump box 20 starts to supply liquid to the nozzle 6. The nozzle 6 sprays the antifreeze liquid to the switch, thereby playing an antifreeze role. The connecting pipe 18 rotates along the inner wall of the drain pipe 21 without affecting the infusion and will not cause the water pipe to twist. The limiting ring 19 plays a limiting role. The side of the protective cover 30 is provided with a through hole adapted to the shape of the fixing seat 1, and the protective cover 30 plays a protective role And it can be disassembled from the rail car 12 for easy maintenance of the internal equipment. The snow melting process is fully mechanically operated without manual assistance, which greatly improves safety and work efficiency. It solves the problem that most traditional snow melting methods rely on manual operation, consume a lot of manpower, have low snow melting efficiency, and frequently work on both sides of the railway turnout. The safety is difficult to ensure, which affects the normal operation of the train. After the snow melting is completed, the output end of the motor 2 is reversed to make the support seat 5 close to the fixed seat 1 and return to the initial position without affecting the passage of the train. By setting a wire pipe winding device, the power supply and liquid supply can adapt to the change of the position of the support seat 5 and avoid the power supply line and water pipe being exposed, thereby extending the service life and avoiding the power supply line or water pipe being drawn into the track and crushed by the train.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
