The lifting mechanism 4 comprises a lower limiting hydraulic cylinder 11, a lifting hydraulic cylinder 12 and an upper limiting hydraulic cylinder 13; the lower limiting hydraulic cylinder 11 is horizontally fixed on the main box body 1, and the free end of the lower limiting hydraulic cylinder 11 moves towards the operation cylinder 3 along the horizontal direction to realize clamping connection with the positioning groove 10; the lifting hydraulic cylinder 12 is vertically fixed on the lower limiting hydraulic cylinder 11, and the free end of the lifting hydraulic cylinder 12 moves upwards in the vertical direction; the upper limiting hydraulic cylinder 13 is horizontally fixed at the free end of the lifting hydraulic cylinder 12, and the free end of the upper limiting hydraulic cylinder 13 moves towards the operation cylinder 3 along the horizontal direction to realize clamping connection with the positioning groove 10. The lifting mechanism and the positioning groove 10 are matched to realize the function of moving the operation barrel 3 up and down.
The bottom end of the operation cylinder 3 is provided with an anti-seepage claw 14; the anti-seepage claw 14 is bent inwards; a grid-shaped reinforcing plate 15 is arranged above the anti-seepage claw 14. Considering that when the operation cylinder 3 is lowered into the seabed sediment, the phenomenon of sediment water seepage can occur after a long time, therefore, the sediment at the bottom is compacted through the design of the anti-seepage claw, and the phenomenon of seawater seepage is prevented.
A spraying and flushing device is arranged in the operation cylinder 3; a plurality of the spraying and punching devices are longitudinally arranged around the center of the operation barrel 3 as an axis; the spraying and punching device comprises a spraying and punching main pipe 6, a plurality of spraying and punching heads 7 and a converter; the spraying and punching main pipe is longitudinally fixed inside the operation barrel 3, the upper end of the spraying and punching main pipe is connected with the pump station 5 through a connecting pipeline, the lower end of the spraying and punching main pipe is connected with a plurality of spraying and punching heads 7 through converters, and the spraying and punching heads 7 penetrate through the upper end of the anti-seepage claw 14 and are positioned outside the anti-seepage claw 14. The reason for designing the jetting device is that after the operation of the operation cylinder 3 is completed, the operation cylinder needs to be pulled up and then moved away through the tug boat, and in the pulling-up process, the bottom generates a large adsorption force with the sediment on the seabed due to the self gravity, so that the sediment on the bottom needs to be scattered through the jetting device.
The spraying and punching jet pipes on the spraying and punching head 7 are outwards inclined and are provided with a plurality of spraying and punching jet pipes by taking the center of the spraying and punching head 7 as an axis. If the vertical design is adopted, a part of silt enters the jet nozzle 7 in the placing process to cause blockage, so that the inclined design is adopted to reduce the blockage.

The auxiliary buoyancy tanks 2 are mounted on two sides of the main tank body 1 and fixed through connecting rods 9, and one side end face of each auxiliary buoyancy tank 2 is in a tapered shape. The auxiliary buoyancy tank 2 can provide larger ballast gravity or buoyancy on one hand, so that the operation cylinder 3 can be conveniently lowered and pulled up, and simultaneously, the seawater resistance borne by the operation cylinder during marine consignment is reduced by optimizing the structure.
The main tank body 1 and the auxiliary buoyancy tank 2 are both composed of a plurality of independent empty chambers. The stability of the adjusting platform main body is realized through an independent empty cabin.
The working principle is as follows:
the main tank body 1 and the auxiliary buoyancy tank 2 form a platform tank body, a plurality of ballast water tanks are contained in the platform tank body, and relevant auxiliary supporting facilities are arranged in the platform tank body, firstly, after the facilities are wet towed to a designated position through towing boats by utilizing buoyancy provided by the main tank body 1 and the auxiliary tank 2, the platform is precisely positioned by three towing boats at the moment so as to ensure the relative stability of the position of the platform, and the specific reference is made to fig. 1.
Then, the lowering operation is started by the self-gravity of the lifting device and the operation cylinder 3, specifically, firstly, the free end of the lower limiting hydraulic cylinder 11 is inserted into the positioning groove 10 below to realize the relative fixation with the operation cylinder 3, then, the lifting hydraulic cylinder 12 moves upwards to enable the upper limiting hydraulic cylinder 13 to reach the positioning groove 10 above and insert the free end into the positioning groove 10 above, at the moment, the free end of the lower limiting hydraulic cylinder 11 is drawn out by the lower limiting hydraulic cylinder 11, then, the lifting hydraulic cylinder 12 moves downwards to realize the downward movement of the operation cylinder 3, then, the free end of the lower limiting hydraulic cylinder 11 is inserted into the positioning groove 10 in the middle, and the operation is repeated, and the operation is specifically referred to fig. 2.
In this process, ballast leveling is performed by adjusting the amount of water in a plurality of empty tanks in the main tank body 1 and the auxiliary buoyancy tank 2 to match the sinking of the work drum 3 to a predetermined depth. As the lower end of the barrel 3 is embedded in the silt, an opposite sealing surface is formed and the silt at the bottom of the barrel is compacted by the anti-seepage claw 14 to achieve the anti-seepage effect, which is specifically referred to fig. 3.
In order to ensure the integral stability of the platform, the steel piles can be driven into the operation barrel through the fixing pile guide grooves 8, and then the seawater in the operation barrel 3 is pumped out through the pump station 5, so that a dry operation environment of the sea bottom surface is realized, and operations such as well sealing, cutting and dismantling are conveniently carried out. After accomplishing the construction operation, need pull up the platform wholly and transport away, spout through spouting the silt that dashes the device to 3 bottoms of operation section of thick bamboo this moment and dash for it is not hard up to receive extruded silt originally, in order to reduce its adsorption affinity, makes things convenient for operation section of thick bamboo 3 to move up, and the process of pulling up is similar with the process of transferring, therefore no longer gives unnecessary details. In this process, the water in the main tank 1 and the auxiliary float 2 can be drained to increase the buoyancy thereof, thereby facilitating the entire removal of the work cylinder 3.
