The pantograph is generally installed on the top of the locomotive or motor car, and the power of the substation is transferred to the locomotive through the friction with the contact wire. In rainy and snowy weather, the surface of the catenary will freeze, which will affect the pantograph to accept power. Therefore, the existing pantograph ice breaking device for electric locomotive has been continuously innovated and developed, but there are still some problems with the existing pantograph ice breaking device.
[0003] The existing pantograph ice breaking device needs to contact the catenary for a long time, and the friction between the pantograph ice breaking device and the catenary will cause damage to the catenary, thereby reducing the service life of the catenary, which is not convenient for the staff to use. Therefore, a pantograph ice breaking device for electric locomotive is needed to solve the above problems. UTILITY MODEL CONTENTS

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. When the electric locomotive turns, the second connecting plate slides inside the sliding plate via a slider, allowing it to slide at the bottom of the sliding plate. The second return spring then causes the second connecting plate to slide, thus bringing the ice-breaking assembly into close contact with the contact wire. This prevents excessive friction between the ice-breaking assembly and the contact wire, which could damage it. The rotating block rotates inside the rotating frame, allowing the pantograph ice-breaking device to adjust according to the turning angle of the electric locomotive. This prevents excessive pressure on the contact wire during turns, thus avoiding damage to the contact wire.
