Embodiment 1

[0027] Such as Figure 1-7 As shown, a blowout preventer that is easy to fix includes a housing 1, a fixing plate 15 located on both sides of the housing 1 and a first equipment box 2 located above the fixing plate 15, the first The equipment box 2 is two groups, which are respectively fixed on both sides of the casing 1. The fixing plate 15 is used to fix the blowout preventer at the wellhead so that the blowout preventer can seal the oil well; the casing 1 is equipped with The first through hole 11, the oil delivery pipe can be inserted into the oil well from the first through hole to perform oil pumping work; the first equipment box 2 is provided with a sealing assembly and a driving member for driving the sealing assembly to move; The bottom of the first equipment box 2 is provided with a support seat 16; the support seat 16 is set as a triangular structure, and the first equipment box is fixed on the side wall of the housing by using the principle of triangular stability;...

Embodiment 2

[0039] Such as Figure 8-10 As shown, the difference between this embodiment and Embodiment 1 is that: the fixing plate 15 is provided with a fixing device, and the fixing device is detachably connected with the fixing plate 15; the blowout preventer is fixed by the fixing device, increasing The fixing effect of the blowout preventer enables the blowout preventer to be fixed more stably at the wellhead and has a good blowout prevention effect; through the detachable connection between the fixing device and the fixing plate, the fixing device can be easily repaired and maintained, and the fixing time can be extended. The service life of the device.

[0040] Described fixing device comprises the second equipment box 4 that is located on described fixed plate 15, is located at the hydraulic cylinder 41 in described second equipment box 4, is located at the rotary motor 44 on the piston rod of described hydraulic cylinder 41 and The positioning drill bit 45 arranged on the output...

Embodiment 3

[0044] Such as Figure 11-12 As shown, the difference between this embodiment and Embodiment 1 is that a fixing assembly is also provided on the inner wall of the first through hole 11; the oil delivery pipe inserted into the blowout preventer is fixed by the fixing assembly, so as to prevent the oil delivery pipe from The vibration will affect the connection effect between the oil pipeline and the blowout preventer, improve the sealing performance of the blowout preventer, and avoid the occurrence of blowout accidents.

[0045] The fixing assembly includes a second mounting plate 5 disposed on the inner wall of the first through hole 11 , a connecting spring 54 disposed on the second mounting plate 5 , and a fastener fastened to the connecting spring 54 . Plate 51; two sets of fixing components are respectively installed on both sides of the inner wall of the first through hole. After the oil delivery pipe is inserted into the first through hole, the oil delivery pipe is plac...
