[0003] At present, due to the abundant offshore wind energy resources and the feasibility of current technology, the ocean will become a rapidly developing wind power market. The current installation of offshore wind fans requires the pre-installation of steel pipe piles at sea to ensure the stability of the subsequent fans. However, the pipe piles need to be vertical during installation to prevent subsequent tilting.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0028] like Figures 1 to 9 As shown, the load-bearing plate 2 is located inside the steel pipe pile 1, and the top of the load-bearing plate 2 is fixedly connected to the load-bearing plate 3 through an opening. The top of the load-bearing plate 3 is provided with an arc groove 4 that extends through to the bottom. The inside of the arc groove 4 is connected with a ball 5 that is rolled therein, and the bottom of the ball 5 is fixedly connected to the gravity column 6 through a fixed block. An annular groove 26 is provided on the edge side of the top of the load-bearing plate 3, and a button 7 is fixedly installed on the bottom of the inner cavity of the annular groove 26 through a connecting block, and several buttons 7 are arranged in a ring shape, and the top of the ball 5 is fixedly connected to an umbrella-shaped frame 8 used in conjunction with the button 7 and the annular groove 26 through a fixed block.

[0029] Specifically, the bottom of the inner cavity of the load-bearing plate 2 is rotatably connected to the annular rotating plate 27 through a bearing member, and teeth 9 are provided on the edge side of the top of the annular rotating plate 27, and a number of teeth 9 are equidistantly provided in a ring shape. The front and rear parts of the top of the annular rotating plate 27 are rotatably connected to the turning handle 10 through the bearing member, and the top of the turning handle 10 passes through the load-bearing plate 2 and extends to the upper part of the load-bearing plate 2. The top of the load-bearing plate 2 is provided with an annular rotating groove 28 for use with the turning handle 10.

[0030] In order to enable the U-shaped frame 15 to be extended and docked with the rack plate 21, the outer side of the bearing plate 2 is fixedly connected to the connecting frame 11 through a fixing plate, and six connecting frames 11 are arranged in a ring at equal intervals. A square opening 20 is opened at the end of the connecting frame 11 away from the bearing plate 2, and a square threaded cylinder 12 is slidably installed on the inner side of the square opening 20. The inner side of the square threaded cylinder 12 is threadedly connected to a threaded rod 13. The end of the threaded rod 13 close to the bearing plate 2 passes through the bearing plate 2 and extends to the interior of the bearing plate 2. The threaded rod 13 extends to one end of the inside of the load-bearing plate 2 and is fixedly connected to a gear 14 that meshes with the teeth 9. The end of the connecting frame 11 away from the load-bearing plate 2 is fixedly connected to a U-shaped frame 15 through a fixed block. The inner side wall of the steel pipe pile 1 is fixedly connected to a rack plate 21 used in conjunction with the tooth block 19, and the number of rack plates 21 is the same as that of the U-shaped frame 15. A linkage groove 16 is opened on the side of the square threaded cylinder 12 away from the load-bearing plate 2, and the inner cavity of the linkage groove 16 is fixedly connected to an electric telescopic rod 17.

[0031] In order to fix the U-shaped frame 15 and the rack plate 21, a recovery groove 18 is opened on one side of the inner cavity of the U-shaped frame 15. One end of the electric telescopic rod 17 passes through the square threaded cylinder 12 and the U-shaped frame 15 in sequence and extends to the inside of the recovery groove 18. The end of the electric telescopic rod 17 extending into the recovery groove 18 is fixedly connected to a tooth block 19 used in conjunction with the recovery groove 18.

[0032] In order to enable the staff to monitor the verticality of the steel pipe pile 1 in real time, a warning light 23 used in conjunction with the button 7 is fixedly connected to the top of the detection platform 22 through a connecting plate, and the number of warning lights 23 is the same as the button 7. A top plate 24 is placed on the top of the steel pipe pile 1, and a cable 25 is fixedly connected to the edge side of the bottom of the top plate 24, and the bottom of the cable 25 is fixedly connected to the top of the load-bearing plate 2. The warning light 23 is an LED remote control light and can be operated in conjunction with the button 7.

[0033] The working principle of the present invention is as follows: when in use, the staff first places the bearing plate 2 on the inner side of the steel pipe pile 1, and then according to the size of the inner diameter of the steel pipe pile 1, holds the turning handle 10 by hand and drives the annular rotating plate 27 to rotate. When the annular rotating plate 27 rotates, it drives the threaded rod 13 to rotate through the engagement of the gear 14, and then the square threaded cylinder 12 extends to the outside of the bearing plate 2 under the limit of the square mouth 20. When the U-shaped frame 15 at one end of the square threaded cylinder 12 is engaged with the rack plate 21, the square threaded cylinder 12 is rotated. The load-bearing plate 2 is stopped at this time. At this time, the load-bearing plate 2 has been limited. Then the staff lowers the load-bearing plate 2 to the lower part of the inner cavity of the steel pipe pile 1 through the top plate 24 and the cable 25. The U-shaped frame 15 can limit the load-bearing plate 2. When the load-bearing plate 2 is lowered to the inside, the top plate 24 is engaged with the top of the steel pipe pile 1. At the same time, the electric telescopic rod 17 starts to push the tooth block 19 out from the inside of the recovery groove 18 and meshes with the rack plate 21. At this time, the load-bearing plate 2 is in a fixed state to prevent falling and rolling over. After the installation is completed, the staff uses a crane to lift the steel pipe pile 1 for installation. During the installation process, if the steel pipe pile 1 tilts and cannot reach a vertical state with the horizontal plane, the bearing plate 2 will also tilt with the steel pipe pile 1. At this time, the ball bearing 5 will roll inside the arc groove 4, and the weight of the gravity column 6 will pull the ball bearing 5 vertically downward. At the same time, the rotation of the ball bearing 5 will drive the umbrella frame 8 to rotate in a circular shape. One side of the umbrella frame 8 will press the button 7 on the tilted side. When the umbrella frame 8 presses the button 7, the warning light 23 on the top of the inspection table 22 will light up accordingly. The staff can adjust the steel pipe pile 1 according to the number and direction of the warning lights 23. When the ball bearing 5 is stable, the umbrella frame 8 does not press the button 7, and the corresponding warning light 23 goes out. When the steel pipe pile 1 is installed, the staff starts the electric telescopic rod 17 to retract the tooth block 19, and then pulls the bearing plate 2 out of the interior of the steel pipe pile 1 through the top plate 24 and the cable 25, and then carries out subsequent installation.

[0034] Furthermore, a load-bearing plate is installed on the inner side of the load-bearing plate, and a ball is connected to the top of the load-bearing plate using an arc groove. The ball can always swing vertically under the pull of the gravity column. The swing of the ball can drive the umbrella-shaped frame to roll in the annular groove and press the button on the corresponding side, so that the corresponding warning light can also be lit. This setting enables the staff to monitor the vertical state of the steel pipe pile online in real time and continuously, and make timely adjustments, which greatly facilitates the use of the staff, while also reducing the installation cost and providing convenience for the installation of offshore wind power.

[0035] Furthermore, by installing a connecting frame on the edge side of the load-bearing plate and installing a square threaded barrel inside the connecting frame, this arrangement can enable the square threaded barrel to drive the U-shaped frame to extend and dock with the rack plate through the rotation of the annular rotating plate, thereby limiting the load-bearing plate to prevent deviations in lifting and lowering. At the same time, it can also be applied to steel pipe piles with different inner diameters, greatly improving the overall practicality and functionality of the device.
