Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power foundation scour prevention and control, in particular to an underwater cemented riprap conduit device. Background Art

[0002] The marine environment conditions where offshore wind farms are located are very complex. The wind turbine foundation is subjected to the reciprocating effects of various environmental loads such as wind, waves, and currents throughout its life cycle. The bearing capacity and structural deformation of the wind turbine foundation are important guarantees for the safe and stable operation of wind turbines. In the ocean current environment, the presence of structures such as wind turbine foundations causes complex three-dimensional flow patterns to form around them, resulting in the local bed surface velocity being greater than the starting flow velocity of the bed, which in turn causes the local bed to be transported along the flow direction, forming local scour pits around the structure. The scour and protection of offshore wind power foundations are not only related to the safety of offshore wind farms during operation, but also play an important role in the optimal design of the foundation structure. It has become an important issue that needs to be considered in the design stage of offshore wind farms.

[0003] Riprap is the preferred anti-scouring measure for offshore wind farms due to its advantages of convenient material acquisition, simple construction, and adaptability to terrain changes. After the graded stone filling is completed, underwater protective agent is placed on the surface of the riprap, and a new type of underwater self-protecting concrete is poured to form a composite structure of riprap + cemented riprap. Therefore, an underwater cemented riprap conduit device is designed.

[0004] In the prior art CN117684573A, the float needs to be recovered repeatedly, and when in use, the user needs to place the float at an extremely high position. When the pipeline is too long, it takes a long time to repeatedly adjust the position of the float.

[0005] When the sea is windy and rough, the riprap construction vessel can adjust the height of the pouring conduit through the mechanical arm. However, since it is impossible to monitor the real-time height of the bottom of the pouring conduit, there will be a delay when the mechanical arm passively adjusts the height, which will cause the material poured in the pouring conduit to shift, causing riprap to leak, and causing the pouring conduit on the water surface to collide with the side of the aggregate hopper, damaging the feed pipe and the protective agent feed pipe wall. After the riprap conduit under the water surface is damaged, material leakage or pipeline blockage will occur. Utility Model Content

It is prevented that the first riprap tube 5 touches the foundation stone and damages the first riprap tube 5. An extended steel pipe 2 is added below the first riprap tube 5, and the steel pipe 2 is sleeved outside it, making full use of the elasticity of the first riprap tube 5 to adapt to the change of tide level at sea. The bottom of the second riprap tube 6 is fixedly connected to the inner wall of the first sliding flange 501, and the outer wall of the first sliding flange 501 is slidably fitted to the inner wall of the first riprap tube 5; a first clamping ring 5011 is welded to the inner wall of the top of the first riprap tube 5, and the first clamping ring 5011 prevents the first sliding flange 501 from falling off from the top of the first riprap tube 5. A single-beam depth sounder 3 is connected to the bottom outer wall of the first riprap conduit 5 , and a sensor is provided on the single-beam depth sounder 3 to transmit water depth data back to the monitoring system 301 through a data line;

The trumpet-shaped outlet of the collecting hopper 10 is connected to the inlet center of the pouring conduit 4. The hull of the construction vessel 12 floats on the AA sea surface and floats up and down and left and right at will.

[0049] See also Figure 3~Figure 9The operating table 11 transmits the B riprap, which is sequentially settled at a designated position through the collecting hopper 10, the casting conduit 4, the steel pipe 2, and the magnetic opening and closing device 1; the magnetic opening and closing device 1 includes three first permanent magnets 101, a buffer belt 1011, three second permanent magnets 102, four iron blocks 103, ten first gears 104, ten first rotating shafts 1041, ten push rods 105, a plurality of saw teeth 1051, four sensors 106, ten second gears 107; ten second rotating shafts 1071, ten second reversible motors 1072, and ten first reversible motors 1042.

[0050] See also Figure 3~Figure 7 , the operation mode of the reversible motor on one side of the magnetic opening and closing device 1 is used as an example for explanation.

When the first reversible motor 1042 drives the first gear 104 to rotate counterclockwise through the first rotating shaft 1041, the second reversible motor 1072 drives the second gear 107 to rotate clockwise through the second rotating shaft 1071, and cooperates to pull the push rod 105 back to adjust the outlet of the magnetic opening and closing device 1, and the material flow rate of the riprap body B inside the casting conduit 4 is increased accordingly.

[0051] A plurality of first reversible motors 1042 and a plurality of second reversible motors 1072 are fixedly connected to one side of the inner wall of the shell of the magnetic opening and closing device 1; the output end of each of the first reversible motors 1042 is connected to the first rotating shaft 1041, and each of the first rotating shafts 1041 is fixedly connected to the first gear 104; the output end of each of the second reversible motors 1072 is connected to the second rotating shaft 1071, and each of the second rotating shafts 1071 is fixedly connected to the second gear 107; each of the first gears 104 is respectively rotatably connected to the sawtooth 1051 on one side of each push rod 105; each of the second gears 107 is respectively rotatably connected to the sawtooth 1051 on the other side of each push rod 105; the five push rods 105 on one side of the magnetic opening and closing device 1 are respectively connected in parallel with the first permanent magnet 101 and the iron block 103, and the five push rods 105 on the other side of the magnetic opening and closing device 1 are respectively connected in parallel with the second permanent magnet 102 and the iron block 103, and the iron block 103 is respectively installed between the two vacancies formed by the three first permanent magnets 101. An iron block 103 is installed between two vacancies formed by the three second permanent magnets 102 .

[0052] An iron block 103 is arranged in parallel between every two first permanent magnets 101; an iron block 103 is arranged in parallel between every two second permanent magnets 102; and the iron block 103 and the permanent magnets are arranged crosswise to reduce the number of first permanent magnets 101 and second permanent magnets 102 used, thereby saving costs.

[0053] A buffer belt 1011 is provided on one side of the outer wall of each first permanent magnet 101 and each second permanent magnet 102 to buffer the pressure between the first permanent magnet 101 and the second permanent magnet 102 when closed, so as to prevent the first permanent magnet 101 and the second permanent magnet 102 from being damaged by collision.

[0054] Figure 3 In the figure, the magnetic opening and closing device 1 is fixedly connected to the trapezoidal outlet of the steel pipe 2, and 8 push rods 105 are installed in the shell of the magnetic opening and closing device 1; a plurality of equally spaced saw teeth 1051 are fixedly provided on both sides of the push rod 105; the saw teeth 1051 on both sides of each push rod 105 are respectively rotatably engaged with the first gear 104 and the second gear 107, and the first gear 104 is fixedly connected to the first rotating shaft 1041; the first rotating shaft 1041 is connected to the bottom output end of the first reversible motor 1042;

Each first reversible motor 1042 and each second reversible motor 1072 are fixedly connected to the inner shell of the magnetic opening and closing device 1 through a fixing block.

[0056] Since the reversible motor causes greater wear and heat to the bearings of the first rotating shaft 1041 and the second rotating shaft 1071, and is prone to corrosion when immersed in a deep, high-pressure, humid and dark seawater environment for a long time, the first rotating shaft 1041 and the second rotating shaft 1071 of the new invention are preferably silver-plated on the surface and stainless steel on the inside; the first gear 104, the second gear 107, and the sawtooth 1051 are silver-plated on the surface and chromium on the inside; the permanent magnet pair can adjust the speed of the reversible motor to 0.5rpm~10rpm to prevent excessive speed and excessive load, which will damage the life of the brake pads inside the first reversible motor 1042 and the second reversible motor 1072, and damage the first permanent magnet 101 and the second permanent magnet 102 at the same time.
