8. The hydraulic reinforced sealing seabed oil and gas pipeline positioning mechanism of claim 1, wherein: the cable (22) is arranged on the outer side of the warm-keeping outer cylinder (9), and branch lines of the warm-keeping outer cylinder (9) are electrically connected with the power-on slip ring (7) and the heating element (23).
9. The hydraulic reinforced sealing seabed oil and gas pipeline positioning mechanism of claim 1, wherein: the anti-blocking dredging method of the seabed oil and gas pipeline positioning mechanism comprises the following steps:
s1, when butt joint installation and positioning are carried out between the end parts of the pipelines, the end parts of the pipeline bodies (1) are positioned between the pipe ends of the pipeline bodies (1) through the use of the composition structure of the extrusion ring (2) and the inner ring (3), the end parts of the pipeline bodies (1) are coaxially positioned, the installation and the use of the sealing rubber gasket (4) can prevent the sealing leakage problem between the connection parts of the composition structure of the extrusion ring (2) and the inner ring (3) and the pipeline bodies (1), and meanwhile, the positioning ring (10) and the annular support piece (11) are fixed on the outer walls of the pipeline bodies (1) and the warm-keeping outer cylinder (9) through the installation and the use of the first bolt piece (12) and the second bolt piece (14) respectively;
s2: under the installation action of the second bolt pieces (14), the positioning cylinder (13) is positioned and reinforced between the annular support pieces (11), the end parts of the pipeline body (1) are positioned and reinforced in a wrapping mode through the installation, positioning and reinforcing of the positioning cylinder (13), leakage between the end parts of the pipeline body (1) is prevented when the pipeline body is used, meanwhile, when the pipeline body (1) is placed on the seabed, the waterproof rubber belt (18) is deformed under the influence of the pressure of water pressure, the positioning bolt (17) and the pressure cylinder (16) perform relative telescopic movement, the lower end arrangement position of the positioning bolt (17) is changed, and when the positioning bolt (17) is pushed downwards, the pull rod (19) is pulled through the connecting rod (21), so that the pull rod (19) moves towards the positioning bolt (17) under the clamping sliding connection action of the sliding block (20) and the positioning cylinder (13), and simultaneously, due to the mutual clamping connection action between the positioning bolt (17) and the positioning ring (10), under the combined action of the positioning bolts (17) and the pull rods (19) which are distributed in a staggered manner, the positioning ring (10) pushes the pipeline body (1), so that the pipeline body (1) moves towards the opposite direction, the connecting end of the pipeline body is positioned and reinforced in a pressurized manner, the sealing and connecting positioning stability of the connecting part of the end part is maintained, and the problems of expansion crack and leakage caused by blocking expansion are prevented;
s3: when the oil inside the pipeline body (1) circulates, the oil circulates through the pushing guide vanes (8), so that the rotating ring (5) and the inner ring (3) perform relative rotating motion under the installation effect of the connecting piece (6), the inner ring (3) and the guide vanes (8) which perform rotating motion can drive the oil which flows linearly to stir, the phenomenon that the oil is layered and deposited under the action of gravity to influence the normal conveying effect of the pipeline is avoided, and meanwhile, under the auxiliary installation effect of the cable (22), the cable (22) can be continuously powered for the installation and use of the heating element (23) through the electrified sliding ring (7), so that the rotating ring (5) in the rotating process can heat the oil again in the conveying process to prevent blockage, and when the blockage occurs inside the connecting end of the pipeline body (1), the conveying pushing acting force of the oil and the continuous heating effect of the heating element (23) in the inner ring (3) are achieved, can carry out the thermal solution of fluid, the mediation when condensing the fluid of blocking and appearing piling up the jam.
