[0030] The oil collection structure includes an oil collection box 201, with a splash-proof cover 202 mounted on top. An oil extraction pipe 203 is mounted near the bottom of the left and right middle portions of the outer surface of the oil collection box 201, and a connector 204 is mounted on one end of the oil extraction pipe 203. The oil collection box 201 is fixedly mounted in the middle of the bottom surface of the fuel hydrant well 1. The splash-proof cover 202 is a curved plate.
