Description

The present invention relates to the technical field of fastening the foundation for wind parks, in particular a high-strength, wind-resistant platform pile foundation for offshore wind parks.

Offshore wind farms mostly refer to offshore wind farms with shallow water. Compared to onshore wind farms, the main advantages of offshore wind farms are that they do not occupy land resources, are essentially unaffected by topography and landforms, and have higher wind speeds and a greater individual capacity of wind turbines, as well as higher annual usage hours. When building offshore wind farms, the strong wind in the sea area places high demands on the wind resistance of the platform pile foundation.

When the existing wind-resistant platform pile foundations for offshore wind farms are in operation, they are exposed to strong winds with high strength for a long time. Due to the influence of the geomorphology of the seabed, the pile foundations are not stable and inclined, which affects the efficiency of electricity generation from wind farms. At the same time, when pile driving for pile foundations, the driving depth is impaired due to the harder geology under the seabed.

In view of the disadvantages of the prior art, the present invention provides a high-strength, wind-resistant platform pile foundation for offshore wind farms, which not only has the advantage of increasing the contact area between the pile foundation and the seabed, at the same time improving the depth and contact area of the pile foundation and the Improving the stability of the pile foundation, but also solves the problems of a small contact area between the wind-resistant platform pile foundation for wind farms and the seabed, poor stability and a small contact area when it is inserted into the seabed.

To achieve the above object, a high-strength, wind-resistant platform pile foundation for offshore wind farms is proposed according to the present invention, comprising a mounting box, wherein a first mounting plate is fixedly mounted in an inner cavity of the mounting box, with the front and rear sides of the a first support rod is rotatably mounted on the first mounting plate, a second support rod is rotatably mounted on the opposite sides of the two first support rods, a first spring is fixedly mounted on the opposite sides of the two second support rods, with the far apart Sides of the two first support rods a connection block is fixedly mounted in each case, the widely spaced sides of the two connection blocks each penetrating the assembly box and extending to the outside of the assembly box, with the far apart side In each of the two connecting blocks, a support plate is fixedly mounted, a slide rod being fixedly mounted on the bottom of the inner cavity of the assembly box, and the upper end of the slide rod penetrating the first mounting plate and extending to the outside of the first mounting plate, the outer surface of the Slide bar, a slide block is slidably mounted, the top of the second support bar being rotatably connected to the bottom of the slide block.

The principle of operation of this embodiment is described below. First the operator guides the insertion column 11 on the pile foundation to a certain depth in the seabed and then hits the extrusion column with a heavy hammer 12th . The extrusion column 12th drives the sliding block 9 in such a way that it sits on the slide bar 8th moves down and drives the second support rod 4th in such a way that it runs. Meanwhile, the first spring begins 5 to stretch, and the second support rod 4th rotates to the first support pole 3 drive so that it begins to rotate. The first support rod 3 drives the connection block 6th so that it extends outward, and the connecting block 6th drives the support plate 7th so that it moves down until the support plate 7th touches the ocean floor. When the extrusion column 12th in the assembly box 1 enters, drives the telescopic rod 13th under the force of the second spring 14th the locking block 15th such that it moves and the extrusion column 12th in the assembly box 1 latches, whereby the support effect of the pile foundation is realized. During the extrusion process, the slide block drifts 9 the threaded block 18th by the conductive rod so that it moves downward and drives the threaded rod 17th in such a way that it rotates and drives the drilling column 20th in such a way that it rotates. In this way the drilling column becomes 20th Drilled in the seabed so that the contact area between the bottom of the pile foundation and the seabed is greater and the insertion depth is deeper.

In summary, the high-strength wind-resistant platform pile foundation for offshore wind farms can be designed as follows. The extrusion column 12th drives the sliding block 9 so that it moves down and propels through the first support rod 3 the second support rod 4th in such a way that it turns and runs. The second support rod 4th pushes through the connection block 6th the support plate 7th against the surface of the seabed, whereby the supporting effect of the pile foundation is realized. Then through the interaction of the sliding block 9 and the conductive rod of the threaded block 18th driven to move downward and the threaded block 18th drives the drilling column 20th through the threaded rod 17th in such a way that the drilling column 20th rotates and can be drilled into the seabed so that the pile foundation is inserted deeper into the seabed and the contact area between the bottom of the pile foundation and the seabed is greater.
