Anti-collision buffering large circular swing gate for channel

The utility model provides an anti-collision buffering large circular swing gate for a channel, and relates to the technical field of circular swing gates, the anti-collision buffering large circular swing gate comprises a swing gate box body, one side of the swing gate box body is rotatably provided with a swing gate gate, and the inner part of the swing gate box body is provided with a mounting rod 1. According to the buffer device, when the buffer plate is stressed and extruded, the buffer plate moves in the stressed direction, the connecting rod on one side of the buffer plate moves to drive the two first connecting bases to be away from each other on the first mounting rod, the first spring is compressed, meanwhile, the second mounting rod on one side of the buffer plate is stressed to push the limiting plate to move in the stressed direction, and the second spring is also stressed and compressed; in the compression process of the first spring and the second spring, external impact force can be counterac
