Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The sealing ring 23 is composed of a plurality of air bags 231, the air bags 231 are evenly distributed in the sealing ring 23, the air bags 231 are connected with the gas expander 28 through air guide pipes, when the gas expander 28 is triggered in the using process, the internal igniter ignites the air bags 231 which release air, so that the expansion rings 22 are driven to expand to be in contact with the outer side pipe wall to realize sealing, a plurality of groups of gas expanders 28 can be arranged in the using process to supply the air bags 231 respectively, the sealing effect is better, in addition, the internal gas is discharged through an exhaust pipeline in the using process, so that the expansion rings retract and the device is convenient to take out, and the exhaust induction head 26 is arranged in the technical scheme, so that the proper exhaust gas release pressure in the using process can be judged.
The air bag 231 is of an elastic air bag structure, the expansion ring 22 is made of wear-resistant rubber elastic materials, and the elastic structure can automatically retract after gas is released, so that the contact with the inner wall of the petroleum pipeline in the use process is avoided.
According to the technical scheme, the sealing effect on the outer side surfaces of the petroleum pipeline and the packer is realized through the matching of the sealing ring 23 and the expansion ring 22 in the implementation process, the contact induction control and the matching of the gas expander are adopted to realize automatic operation control in the implementation process, the control of external equipment is not needed, and when the locking mechanism at the upper end of the taking-out process is separated from the anchoring mechanism at the lower end, the gas in the air bag can be discharged through the signal of the exhaust induction contact 27 so as to be conveniently separated from the pipe wall and taken out.
