The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0029] The working principle of the above embodiment is:

[0030] (1) When in use, align the connection seat 501 with the wellhead and put it in, so that the connection seat 501 can contact the positioning plate 7, and then fix the connection seat 501 on the wellhead by the fixing bolt 6, so that the connection mechanism 5 can be fixed to the wellhead. When installing the blowout preventer, align the positioning hole on the lower connecting pipe 2 with the positioning rod 502 and put it in, and the flange connecting plate on the connecting pipe 2 is in contact with the moving block 504, so that the moving block 504 can move, so that the moving block 504 can drive the spring 503 to be compressed. When the moving block 504 is not in contact with the flange connecting plate, the spring 503 allows the moving block 504 to rebound, so that the moving block 504 can limit the connecting pipe 2, and then fix the connecting pipe 2 and the connection seat 501 by the connecting bolts, so as to facilitate the connection between the blowout preventer body and the wellhead.

[0031] (2) After the connection seat 501 is fixed to the oil well mouth, the fan 506 is started so that the fan 506 can absorb external air through the air inlet pipe 507 and transport the air to the inside of the air bag 509 through the air outlet pipe 508, so that the air bag 509 can be inflated. When the air bag 509 is filled with air, the air bag 509 will fit with the inner wall of the oil well mouth, so that the oil inside the oil well will not overflow from the gap between the connection seat 501 and the oil well mouth.
