The utility model discloses guide pillar formula mooring location offshore platform's working process as follows: firstly, an offshore platform 3 is built on land or in a dock, a plurality of guide sleeves 2 are uniformly distributed on the offshore platform 3, and meanwhile, a guide post 1 is built, when the offshore platform 3 is used, the offshore platform 3 is pulled to the sea, the guide post 1 is longitudinally connected in the guide sleeves 2 in a penetrating manner, a support plate 10 on the outer wall of the guide post 1 is supported by a turnover plate 13 which is arranged below the support plate and is in a horizontal state, at the moment, the guide post 1 cannot move downwards relative to the guide sleeves 2, so that the whole offshore platform 3 floats on the water surface, after the offshore platform 3 is pulled to a specified place by a barge, all turnover plate mechanisms are controlled to be recovered, the turnover plates move towards the outer side and are extracted from the lower part of the support plate 10 (as the guide post 1 is hollow and bears buoyancy in the water, the forward pressure between the support plate 10 and the turnover plate 13 is not large; after the guide pillar is pulled away, the guide pillar 1 loses the support; a valve capable of being controlled remotely is arranged at the bottom of the guide pillar 1, seawater is poured into the guide pillar 1 after the valve is controlled to be opened, and the guide pillar 1 sinks relative to the guide sleeve 2 until the bottom end of the guide pillar 1 is contacted with the seabed; after all the guide columns 1 are fastened on the seabed, the offshore platform 3 is positioned in the horizontal direction;
in the working state, the turning plates 13 in all the turning plate mechanisms are in a recovery state, namely when the guide pillar 1 longitudinally moves in the guide sleeve 2, the turning plates 13 cannot interfere with the support plate 10; because the guide sleeve 2 and the guide post 1 can move relatively, when the sea level changes, the whole offshore platform 3 (including the guide sleeve 2) changes along with the change of the sea level, namely passively does lifting action;
in the elastic supporting mechanism, because the spring 8 always provides thrust for the sliding block 7, the high-strength nodular cast iron balls 9 at the end part of the sliding block 7 are always in contact with the outer wall of the guide post 1, so that when the guide post 1 and the guide sleeve 2 move relatively, the high-strength nodular cast iron balls 9 roll on the surface of the guide post 1; due to the existence of the elastic supporting mechanism, the guide pillar 1 and the guide sleeve 2 are relatively positioned in the horizontal direction, and stable longitudinal relative motion can be realized;
meanwhile, because the spring 8 has a certain telescopic capacity, when the guide sleeve 2 is subjected to horizontal thrust from a certain direction due to sea waves, the spring 8 corresponding to the direction can be automatically compressed (or extended) under the action of external force, that is, the guide sleeve 2 has a certain displacement in the horizontal direction relative to the guide post 1 and the capacity of recovering the initial state, and the guide sleeve and the guide post are flexibly connected in the horizontal direction, and the design can absorb a part of force generated by the impact of the sea waves on the guide sleeve 2;
if the whole offshore platform 3 needs to be moved again, only high-pressure gas needs to be filled into the inner cavity of the guide pillar 1 from the upper part, meanwhile, a valve at the bottom end of the guide pillar 1 is opened again, seawater is discharged from the inner cavity of the guide pillar 1 under the action of air pressure, the buoyancy borne by the guide pillar 1 is larger and larger, and the guide pillar 1 rises relative to the guide sleeve 2 until the buoyancy is larger than the gravity of the guide pillar;
before that, the turning plate 13 in the turning plate mechanism is controlled to extend towards the direction close to the guide post 1, and at this time, the movement tracks of the turning plate 13 and the support plate 10 can interfere with each other, but because the turning plate 13 can turn upwards (as shown in fig. 6), when the support plate 10 contacts the turning plate 13 from the lower part, the support plate can be driven to turn upwards and reversely, that is, the turning plate mechanism does not obstruct the ascending action of the guide post 1 at this time; when the bottom end of the guide post 1 is completely separated from the seabed, high-pressure air stops being filled into the guide post 1, the guide post 1 falls down, and the turning plate 13 cannot turn downwards, so that the turning plate 13 supports the guide post 1 and the guide sleeve 2 to be relatively fixed (namely the guide sleeve 2 supports the guide post 1);
and dragging the offshore platform 3 to a dock for maintenance or other sea areas by using the barge again, and lowering the guide columns 1 again to form a new offshore platform 3.
