Description

Technical Field

[0001] This utility model relates to the technical field of de-icing devices for urban rail transit power supply contact networks, and in particular to a de-icing device for urban rail transit power supply contact networks. Background Technology

[0002] In urban rail transit systems, the overhead contact line, as a critical power supply facility, directly affects the normal operation of trains. However, in cold climates, the contact line is highly susceptible to icing. When the temperature is below freezing and the air humidity is high, water vapor condenses on the contact line and gradually forms an ice layer. The problem of contact line icing is widespread in electrified railways in northern, central, and western China.

[0003] The hazards of icing to the overhead contact system should not be underestimated. On the one hand, icing can cause insulator failure, leading to short circuits and power outages in the contact system, causing trains to lose power and malfunction. On the other hand, icing can hinder the pantograph's power collection process, potentially causing arcing. This not only accelerates wear on the pantograph and contact system but can also lead to safety accidents. Furthermore, severe icing can cause the contact system to bear loads exceeding design standards, resulting in support posts breaking and compromising the structural integrity of the entire power supply system.

[0004] Currently, existing measures to address the problem of icing on overhead contact lines mainly focus on post-incident handling. Common de-icing methods include manual de-icing, high-current thermal melting, and mechanical de-icing. Manual de-icing requires workers to climb onto the roof of the vehicle after power is cut off and remove the ice layer on the contact line by striking it with wooden sticks. This method is not only labor-intensive and extremely inefficient, but also poses significant personal safety risks to workers operating on top of moving vehicles. Mechanical de-icing uses striking devices to knock down the ice on the contact line surface; however, this method has safety issues, easily damaging the contact line during the de-icing process. Furthermore, its information technology level is low, making real-time monitoring of icing difficult, and the equipment integration is poor, resulting in low work efficiency. Therefore, a de-icing device for urban rail transit power supply contact lines is proposed to solve the above problems. Utility Model Content

[0024] In this embodiment, in the drive assembly 21, the fixing frame 211 is fixedly connected to the outer right wall of the fixing base 1, and the drive motor 212 mounted on its back provides power for the entire drive process. After the drive motor 212 starts, its output end drives the rotating shaft 213 to rotate, and the drive gear 214 on the outer wall of the rotating shaft 213 rotates accordingly. Since the right side of the drive gear 214 meshes with the meshing gear 215, the rotation of the drive gear 214 will drive the meshing gear 215 to rotate synchronously. The transmission rod 216 fixedly connected to the inner wall of the meshing gear 215 starts to rotate under the drive of the meshing gear 215.

The bottom of the seat 2110 is fixedly connected to the top of the limiting frame 221, so that the drive assembly 21 and the de-icing assembly 22 form a stable connection. As the transmission rod 216 rotates, the bevel gear 217 fixed at its front and rear ends also rotates. The bevel gear 217 meshes with the bevel gear 218 at the bottom, thereby transmitting the rotation to the bevel gear 218.
