The utility model provides a pump pry block commonly used for sinking a suction barrel foundation of an offshore wind turbine, which is described by taking a pump pry block which can sink and inertia four suction barrels at the same time and is provided with four sets of identical pump valve groups as an example, and is shown in figures 1-4: the pump valve group structure comprises a frame body 8, wherein a butt flange 7 is fixed at the bottom of the frame body 8, four interfaces 7.1 are arranged on the butt flange 7, and each interface 7.1 corresponds to one set of pump valve group. The upper end of each interface 7.1 is communicated with a first passage of a tee joint 1; the second passage of the tee joint 1 is communicated with a three-way valve II 6 fixed at the bottom of the frame body 8 through a pipeline 3, the third passage of the tee joint 1 is communicated with a three-way valve I2 arranged in the frame body 8 through the pipeline 3, and the second passage of the three-way valve II 6 is communicated with a water suction port 5.1 of a water pump 5 fixed in the frame body 8 through the pipeline 3; a second passage of the three-way valve I2 is communicated with a water outlet 5.2 of a water pump 5 through a pipeline 3; and a third passage in the three-way valve I2 and the three-way valve II 6 is directly communicated with the outside. After the wind driven generator foundation with the suction barrels at the bottom is hoisted to the seabed, the barrel bottoms of the suction barrels are sealed by sea mud, the barrel openings of the suction barrels are connected with the interfaces 7.1 of the butt flanges 7 by pipelines, and the connection positions are sealed; when the sinking inertia speed of a certain suction bucket is slow and the seawater in the suction bucket needs to be discharged, twisting the valve bolts of the three-way valve I2 and the three-way valve II 6 to the positions shown in figure 6, and then starting the water pump 5 connected with the valve bolts, the seawater in the suction bucket is discharged into the sea along the directions of the suction bucket → the butt flange 7 → the three-way valve II 6 → the water suction port 5.1 → the water pump 5 → the water discharge port 5.2 → the three-way valve I2; when the sinking inertia speed of a certain suction bucket is high and seawater needs to be injected into the suction bucket, the valve bolts of the three-way valve I2 and the three-way valve II 6 are twisted to the positions shown in figure 7, the water pump 5 connected with the valve bolts is started, and the seawater is injected into the suction bucket along the directions of the three-way valve II 6 → the water suction port 5.1 → the water pump 5 → the water discharge port 5.2 → the three-way valve I2 → the butt flange 7 → the suction bucket. When the seawater is sucked out of the suction bucket, the pressure difference between the seawater inside and outside the suction bucket is increased, and the suction bucket is accelerated to sink; when the seawater is injected into the suction bucket, the pressure difference between the seawater inside and outside the suction bucket is reduced until the seawater is the same, and the sinking inertia speed of the suction bucket is reduced until the sinking inertia stops. By coordinating the opening and closing directions of the valve bolts of the three-way valve I2 and the three-way valve II 6 in the four pump valve groups, synchronous sinking and inertia of the four suction buckets can be realized, and the upper structures of the suction buckets are kept stable.
