Description

Technical Field

[0001] The present invention relates to the technical field of deep sea wind power construction equipment, and in particular to a temporary pile shoe of a suction tube for deep sea wind power and a wind power operation construction method thereof. Background Art

[0002] In the construction of offshore wind power in the deep sea, the positioning of the ship during the lifting operation of the wind power construction platform ship faces many challenges: 1) High requirements for equipment: The water depth of the deep sea wind turbine lifting operation exceeds 70 meters. When the platform ship is stationed, the pile legs are deeply buried in the mud. The platform ship's pile insertion and extraction has high requirements for the platform ship's lifting system. The lifting system needs to have a large power and torque to achieve pile insertion and extraction, which increases the cost of ship construction; 2) Low construction efficiency: When the platform ship's pile legs are deeply buried in the mud, it is necessary to cooperate with the pile punching system to insert and extract piles. The pile punching system needs to flush the silt around the pile legs to reduce friction, but the long pile punching time leads to low construction efficiency. At the same time, the insertion and extraction requires the platform ship to adjust the ballast water to meet the mud entry requirements, and the time required to adjust the ballast water is also long. Therefore, based on the above-mentioned existing technical problems, it is necessary to design a temporary pile shoe structure for suction cylinders for deep sea. Summary of the invention

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments are by no means intended to limit the present invention in any way.

[0042] Example 1

[0043] See also Figure 1 and Figure 2 The temporary pile shoe of the suction tube for deep-sea wind power generation comprises a top platform 1 and a suction tube group 2 which are arranged in sequence from top to bottom.

[0044] The top platform 1 is a platform with a groove in the center. The depth of the groove is 5m, and the diameter of the groove is larger than the outer diameter of the pile leg 6, so that the pile leg 6 can be matched with the groove to realize the positioning and plug-in connection between the structure and the pile leg 6 at the bottom of the platform ship; four lifting ears 105 are evenly distributed along the circumference on the top of the top platform 1; wherein the lifting ears 105 are made of high-strength alloy steel, with good strength and toughness to withstand huge tensile force; in actual offshore wind farm operations, the top platform 1 forms a reliable connection with the crane on the operating ship through the lifting ears 105, so that the temporary pile shoe of the suction cylinder that will be in a floating state can be moved to the next machine position with the operating ship.

[0045] In this embodiment, see Figure 3 The top platform 1 includes a horizontally arranged square platform plate 101, two first vertical plates 102 are vertically fixed at a group of opposite edges on the top surface, and two second vertical plates 103 are vertically fixed at another group of opposite edges on the top surface. The adjacent first vertical plates 102 and second vertical plates 103 are vertically connected and fixed, so that the top platform 1 forms a structure with a groove; the first vertical plates 102 and the second vertical plates 103 are both made of the same rectangular plate, and two horizontal plates 104 are symmetrically fixed on both sides of the top surfaces of the two first vertical plates 102, and the two horizontal plates 104 are simultaneously connected and fixed to the top side edges of the two second vertical plates 103, so that a top surface platform that can be used to install four lifting ears 105 is provided on the top of the four vertical plates, and at the same time has the function of strengthening the structural strength of the top platform 1; the top platform 1 is a steel frame structure as a whole, and meets the load-bearing and force requirements when the auxiliary operation ship is stationed.

[0046] As a preferred technical solution of this embodiment, since the barge does not have pile legs 6, in order to achieve the positioning connection between the structure and the barge, the top sides of the two first vertical plates 102 are respectively centrally provided with inverted trapezoidal notches 1021, and the width of the inverted trapezoidal notches 1021 is adapted to the width of the barge, so that an embedding groove is formed on the top side of the top platform 1; when the temporary pile shoe of the suction cylinder is used in conjunction with the barge, the bottom of the barge can be embedded and matched with the top platform 1.

[0047] A gravel layer 3 is laid in the groove of the top platform 1; wherein, the gravel layer 3 has a thickness of 3m and is formed by the accumulation of gravel with a diameter of 10mm to 50mm; the gravel layer 3 is used to insert the pile legs 6 at the bottom of the hull to stabilize the connection stability between the pile legs 6 and the top platform 1, and also has a buffering effect to achieve the purpose of dispersing the load transmitted by the superstructure, reducing local stress concentration, and reducing the impact force generated when the pile legs 6 are docked with the temporary pile shoes of the suction tube.

[0048] The suction cylinder group 2 includes four suction cylinders 201, which are evenly distributed along the circumference and fixed at the bottom of the top platform 1; the four regularly distributed suction cylinders 201 can ensure that the entire structure is evenly stressed; every two adjacent suction cylinders 201 are welded and fixedly connected by a connecting plate 202 to form a stable whole.

[0049] Four pipeline penetration openings are evenly distributed along the circumferential direction on the bottom surface of the top platform 1, so that the conveying pipes on the top of the four suction cylinders 201 pass through the four pipeline penetration openings respectively; an extension pipe 5 is connected to the end of each conveying pipe, and the length of the extension pipe 5 is 3.5m, so that after the top platform 1 is filled with the gravel layer 3, the other end of the extension pipe 5 can protrude above the gravel layer 3.

[0050] Four pump skids 4 are also arranged on the gravel layer 3 of the top platform 1, which respectively cooperate with the four suction cylinders 201 in the suction cylinder group 2 to drive the four suction cylinders 201 to sink to a stationary state or float to a movable state; the four pump skids 4 are movably arranged on the gravel layer 3 to facilitate removal when connected to the hull.

[0051] Each pump skid 4 includes a submersible pump, an air compressor and a small generator arranged in a box; wherein the small generator is electrically connected to the submersible pump and the air compressor respectively for power supply; during actual operation, the extension pipe 5 is connected to the corresponding port of the submersible pump or the air compressor according to the operation requirements.

[0052] The actual working principle of the above-mentioned pump skid 4 is as follows: when the suction cylinder 201 needs to drive the top platform 1 to sink and insert into the mud surface, the extension pipe 5 is directly connected to the atmosphere, and the suction cylinder 201 first relies on its own weight to drive the top platform 1 to gradually sink to the seabed until it is in a stable state; then the water inlet end of the submersible pump is connected to the extension pipe 5, and the water outlet end of the submersible pump enters the sea through the pipeline, and the submersible pump is started. The submersible pump draws the water in the suction cylinder 201 and discharges it into the sea, so that the suction cylinder 201 continues to sink under the action of negative pressure until it sinks to the specified depth position; at this time, the temporary pile shoe of the suction cylinder is stationed; when the suction cylinder When 201 needs to drive the top platform 1 to float up for displacement, the extension pipe 5 is connected to the water outlet end of the submersible pump, the water inlet end of the submersible pump enters the sea through the pipeline, the submersible pump is started, and the submersible pump injects seawater into the suction cylinder 201, so that the suction cylinder 201 drives the top platform 1 to float up to a certain height; then, the extension pipe 5 is connected to the air outlet end of the air compressor, and the air compressor is started, and the air compressor is used to inject air into the suction cylinder 201, so that the suction cylinder 201 continues to drive the top platform 1 to continue to float up and emerge from the water surface; at this time, the temporary pile shoe of the suction cylinder is in a floating state, so that it can be moved synchronously with the passing working ship or disassembled.

[0053] As a preferred technical solution of this embodiment, the pump skid 4 also includes a PLC controller; the water inlet end of the submersible pump is connected to the other end of the extension pipe 5 through a first delivery pipe, and the water inlet end of the submersible pump is also connected to the sea through a second delivery pipe; the water outlet end of the submersible pump is connected to the other end of the extension pipe 5 through a third delivery pipe, and the water outlet end of the submersible pump is also connected to the sea through a fourth delivery pipe; the air outlet end of the air compressor is connected to the other end of the extension pipe 5 through a fifth delivery pipe; a first electrically-controlled valve is provided on the first delivery pipe, a second electrically-controlled valve is provided on the second delivery pipe, a third electrically-controlled valve is provided on the third delivery pipe, a fourth electrically-controlled valve is provided on the fourth delivery pipe, and a fifth electrically-controlled valve is provided on the fifth delivery pipe; each electrically-controlled valve is electrically connected to the PLC controller respectively, so that the PLC controller can control the sinking and floating of each suction cylinder 201 according to actual operation.

[0054] As a preferred technical solution of this embodiment, in order to facilitate transfer, two lifting ears are symmetrically arranged on the outer side of the box body of each pump skid 4 to facilitate connection with the crane on the operating vessel for easy lifting.
