[0018] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0019] Example 1
[0020] like Figures 1 to 3 As shown, in an embodiment of the first aspect of the present invention, an electric induction heating snow melting device for a railway turnout includes a rail 1, a mounting housing 2 is mounted on one side of the rail 1, a mounting conductor 3 is mounted inside the mounting housing 2, and a first induction coil 4 is connected to one side of the mounting conductor 3. A metal pipe 5 is disposed inside the first induction coil 4, and the metal pipe 5 is filled with water. The longitudinal cross-section of the metal pipe 5 is S-shaped and is adapted to fit the upper and lower sides of the rail 1.
[0021] Specifically, when snow accumulates on a railway switch, affecting traffic and switch replacement, the remote-start installation conductor 3 is energized, causing the first induction coil 4 to induction heat the metal pipe 5, thereby heating the water in the metal pipe 5. Even if the water freezes in a low-temperature environment, it can be quickly heated and melted by induction heating, and the temperature of the water in the metal pipe 5 is transferred outward to the snow, thereby melting the snow. It should be noted that before the heated metal pipe 5 reaches the melting point, the operation of the first induction coil 4 must be stopped to prevent the heated metal pipe 5 from melting. Therefore, the operation time of the first induction coil 4 is limited according to the specific material of the heated metal pipe 5.
[0022] A first expansion airbag 6 is installed in one end of the metal pipe 5 close to the upper side of the rail 1, which is used to fit with the rail 1 after expansion, so that the water vapor rising after the water in the metal pipe 5 boils can come into contact with the rail 1, which can improve the heat exchange efficiency and allow the rail 1 to be heated.
[0023] A reserved hole 7 is also provided on the inner side of the rail 1, and a connecting pipe 8 is provided on the inner side of the reserved hole 7. One end of the connecting pipe 8 is connected to a second expansion airbag 9, and the second expansion airbag 9 and the first expansion airbag 6 are symmetrically arranged about the center of the rail 1. The longitudinal section of the connecting pipe 8 is "U"-shaped, which can heat both sides of the rail 1, thereby achieving a better heating effect on the rail 1.
[0024] Example 2
[0025] like Figure 3 As shown, an electric induction heating snow melting device for a railway turnout includes all the contents of Example 1. In addition, a second induction coil 10 is installed on the outside of the vertical pipe of the metal pipe 5 to reduce the ice melting distance required by the first induction coil 4 when heating the frozen water in the vertical pipe of the metal pipe 5, thereby accelerating the ice melting efficiency.
