[0005] A cross universal joint and a connecting shaft are installed at one end of the output shaft, and the connecting shaft is connected with the operation rods of the upper sealing gate plate, the lower sealing gate plate and the full sealing gate plate of the well packer.

[0006] An operation hand wheel is installed at one end of the operation shaft, the operation hand wheel is connected with the operation shaft by a hexagonal sleeve, a stainless steel button quick-release pin is installed between the operation hand wheel and the operation shaft, a rope falling prevention device is arranged on the stainless steel button quick-release pin, and the other end of the rope falling prevention device is fixed on the operation hand wheel.

[0007] The operation shaft is provided with a digital position counter, which is fixed on the box body by a counter-torque bracket, and a display screen is aligned with an observation window on the box body.

[0008] Rotary maintenance doors are designed on the two sides of the box body, and a back plate is detachable.

[0009] The beneficial effects of this utility model are that it lowers the operation of the well sealing device, enabling fast, simple, and safe well sealing, reducing personal safety and risks, reducing the space occupied at the wellhead, and is economical and practical.

[0017] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings, such as... Figures 1 to 6 Shown:

[0018] The technical solution is that the well sealer low-position control panel consists of a housing 1, an output shaft 2, a chain 3, an operating handwheel 4, a digital position counter 5, an operating shaft 6, and a mounting bracket 8. The well sealer low-position control panel is a box-type module with chain drive and grease lubrication. It is installed on the outside of the drilling rig base and is used to operate the upper half-sealing gate, lower half-sealing gate, and full-sealing gate of the well sealer to the low position. During operation, the operator stands on the ground and rotates the operating handwheel 4.

[0019] like Figure 1 , Figure 2 As shown, the well sealing device has a six-shaft assembly installed inside the low-position control panel, consisting of three output shafts 2 and three operating shafts 6, each with different lengths. The output shafts 2 are arranged vertically and horizontally at the top, while the operating shafts 6 are arranged horizontally and horizontally at the bottom. The three operating shafts 6 and the three output shafts 2 are respectively paired with chains 5 for driving. The three chains 5 are installed in a staggered manner.

[0020] like Figure 3、 Figure 4 As shown in the figure, the output shaft 2 is supported by the bearing 12, the output sprocket 13 is installed at one end of the shaft 11, and the cross universal joint 10 is installed at the other end to realize soft connection. The cross universal joint 10 is further installed with the connecting shaft 9, and the other end of the connecting shaft 9 is connected with the upper sealing board, the lower sealing board, and the full sealing board operating rod of the blowout preventer.

[0021] As shown in the figure, the operating shaft 6 is supported by the bearing 12, and the input sprocket 14 is installed at the second shaft 15.
