Document Type and Number:
Japanese Patent JP6931725
Kind Code:
B2
Abstract:
To provide a noise suppression structure of a current collection device and a current collection system capable of suppressing, by a simple structure, noise radiated from a circumference of a joint part between a current collecting shoe and a shoe supporting part to a wayside.SOLUTION: A noise suppression structure suppresses noise radiated from current collection devices 7A and 7B to waysides Wand W. The current collection devices 7A and 7B are elevated according to a travelling direction of a vehicle 5, and includes a shoe supporting part 9a for supporting a position close to an end of one of a current collecting shoe 8 of the current collection devices 7A and 7B. When a joint part between the current collecting shoe 8 and the shoe supporting part 9a is located at a side far from waysides Wand W, the current collection devices 7A and 7B are switched to an elevating state. When the joint part between the current collecting shoe 8 and the shoe supporting part 9a is located at a side near from the waysides Wand W, the current collection devices 7A and 7B are switched to a lowering state. The noise suppression structure includes a sound insulation plate 13 for blocking the noise radiated from the current collection devices 7A and 7B to the waysides Wand W.SELECTED DRAWING: Figure 1
