Description

TECHNICAL FIELD

[0001] The utility model relates to the field of subway operation and maintenance technology, concretely to flexible contact net double conductor suspension form deicing device. BACKGROUND

[0002] The flexible overhead contact net is adopted in the metro field section and the overhead section of the main line to supply power to the electric passenger car. The flexible overhead contact net is mainly divided into simple suspension and double-accepting double-conductor chain type suspension in structure. The simple suspension is adopted in the single track of the field section and the suspension in the warehouse. The double-accepting double-conductor chain type suspension structure is designed to meet the load flow demand in the field section and the overhead section of the main line.

[0003] The flexible overhead contact net is erected in the open section and is greatly affected by weather factors. When the temperature decreases after raining in the northern region, the contact line is easily covered with ice in a large area. When the flexible overhead contact net is covered with ice, the ice shell with different thicknesses is formed on the surface of the contact line to affect the current collection of the pantograph, and the arc phenomenon is easily generated when the electric locomotive passes through. The ice shell with different thicknesses is easily impacted on the carbon slide plate of the pantograph of the electric locomotive to easily cause the damage of the pantograph equipment and the pantograph net failure.

[0004] In view of the ice covering phenomenon of the flexible overhead contact net, the current traditional treatment measures have two kinds. The first kind is that the maintenance personnel climbs to work after the overhead contact net is powered off, and uses a wooden stick or other tools to knock and remove the ice. The second kind is that the ice knocking rod is used to knock and remove the ice under the live state of the overhead contact net. The traditional ice removing mode has the defects of low work efficiency, large personnel demand, poor work quality, high personnel risk and the like. The flexible overhead contact net single line deicing device makes up for the defects of the above traditional ice removing mode, but is limited by the suspension form of the flexible overhead contact net. For example, the Chinese patent CN221150913U is a flexible overhead contact net deicing device designed and developed by the applicant. The device is only applicable to the deicing of the simple suspension (single contact line) of the flexible overhead contact net, and cannot realize the simultaneous deicing of the two contact lines in the double-accepting double-conductor chain type suspension form, and the deicing efficiency is low.
