A seal plate (10) is arranged on a wellhead of the bottom of the derrick (1). The split trapdoors (8) are arranged in a wellhole in the seal plate (10). The opening device is characterized in that a hinge base (9) is arranged, a lifting rod (11) is connected to the middle of the hinge base, and the upper end of the lifting rod (11) is connected with a pulling rope (5); and a supporting rod (7) is hinged to the inner side of each trapdoor (8), and the other ends of the supporting rods (7) are symmetrically connected to the hinge base (9). The pulling rope (5) is arranged in the trapdoor winch (4), and the pulling rope (5) is connected with the lifting rod (11) through a pulley (3) at the upper portion of the derrick. The opening device has the beneficial effects that compared with a traditional opening device, the opening device for the vertical shaft trapdoors is low in fault rate, safe and reliable.
