[0001] This invention relates to the field of offshore wind turbine installation technology, specifically to an easily controllable offshore wind turbine installation and connection device and method. Background Technology

[0002] Offshore wind turbine installation and connection equipment is mainly used for the installation of wind turbine blades. It allows the wind turbine blades to be adjusted in height and position by hoisting, so that the wind turbine blades can be connected and fixed to the hub. The wind turbine blades and hub are fastened with blade bolts, thereby completing the positioning and connection work.

The two ends of hydraulic cylinder five are hinged to the lifting beam and hydraulic cylinder three, and the two ends of hydraulic cylinder six are hinged to the lifting beam and hydraulic cylinder four.

[0004] Currently, existing offshore wind turbine installation and connection equipment uses a frame for support and is then lifted to a suitable location by a crane. This method cannot improve safety and causes the wind turbine blades to sway during hoisting, which can easily lead to safety issues. Therefore, improvements are needed to address these problems. Summary of the Invention

[0005] To address the problems in the prior art, this invention provides a convenient and controllable offshore wind turbine installation and connection device and method.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a conveniently controllable offshore wind turbine installation and connection equipment and method, including a hoisting connection structure, a side guard frame, a support base frame, a fitting support plate and a reinforcing base. The side guard frame is fixedly connected to the side end of the hoisting connection structure, the support base frame is fixedly connected to the lower end of the side guard frame, the reinforcing base frame is fixedly connected to the support base frame, and the fitting support plate is fixedly connected to the upper end of the reinforcing base frame.

[0007] The hoisting connection structure includes a support limiting component and an adjustment component. The adjustment component is fixedly connected to the side end of the support limiting component. The support limiting component includes a first limiting mechanism, a top cooperating mechanism, and a second limiting mechanism. The first limiting mechanism is fixedly connected to one side of the top cooperating mechanism, and the second limiting mechanism is fixedly connected to the other side of the top cooperating mechanism. The first limiting mechanism and the second limiting mechanism are symmetrically arranged about the top cooperating mechanism.

[0008] Specifically, the first limiting mechanism includes a side plate, a supporting rod, a movable adjustment frame, and a contact extrusion wheel. The lower end of the side plate is fixedly connected to the supporting rod, and the movable adjustment frame is hinged to the supporting rod. The lower end of the movable adjustment frame is rotatably connected to the contact extrusion wheel.

[0009] Specifically, the first limiting mechanism further includes a first cooperating guide rod, an electro-hydraulic control rod, a second cooperating guide rod, and a support pad. The support pad is fixedly connected to the side end of the side plate, and the second cooperating guide rod is fixedly connected to the support pad. The electro-hydraulic control rod is hinged on the second cooperating guide rod, and the lower end of the electro-hydraulic control rod is hinged to the first cooperating guide rod. The first cooperating guide rod is fixed to the side of the movable adjustment frame.

[0010] Specifically, the top mating mechanism includes a buffer reinforcement shaft, a lifting plate, a positioning shaft seat, a support and stabilizing plate, a diagonal frame, a mating docking shaft, a platform frame, a fixed rod, a first contact wheel, a fixed pad, and a hydraulic buffer seat. The lower end of the lifting plate is fixedly connected to the support and stabilizing plate, and the rear end of the lifting plate is fixedly connected to the buffer reinforcement shaft. The side end of the support and stabilizing plate is fixedly connected to the diagonal frame via the positioning shaft seat. The lower end of the diagonal frame is fixedly connected to the mating docking shaft, and the lower end of the mating docking shaft is fixedly connected to the platform frame. The lower end of the support and stabilizing plate is equipped with a hydraulic buffer seat, and the lower end of the hydraulic buffer seat is limited and connected to the platform frame via a fixed pad.

[0011] Specifically, a fixing rod is fixedly connected to the front end of the platform frame, an arc frame is fixedly connected to the front end of the fixing rod, and a first contact wheel is installed at the lower end of the arc frame.

[0012] Specifically, the control components include a mounting partition, a hydraulic controller, a hydraulic telescopic control rod, a reinforced end frame, an arc-shaped guide frame, a buffer platform, and a second contact wheel. The hydraulic controller is mounted on the mounting partition and controls the telescopic adjustment of the hydraulic telescopic control rod. The lower end of the hydraulic telescopic control rod is limited and connected to the reinforced end frame. The side end of the reinforced end frame is fixedly connected to the arc-shaped guide frame. The second contact wheel is rotatably connected to the arc-shaped guide frame via the buffer platform.

[0013] Specifically, the side end of the mounting partition is fixedly connected to the side upright plate, the arc frame and the arc-shaped guide frame are symmetrically arranged, the first contact wheel and the second contact wheel are symmetrically arranged, and the hydraulic controller drives the reinforced end frame, the arc-shaped guide frame and the buffer platform to move longitudinally through the hydraulic telescopic control rod.

[0014] Specifically, the side upright plate is fixed to the lower side of the platform frame, the upper end of the side guard is fixed to the mounting partition, and the side guard, support base, fitting support plate and reinforcing base are integrally molded and fixed to support the fan blades.

[0015] Specifically, the electro-hydraulic control rod extends and retracts, causing the movable adjustment frame to move around the supporting rod, and the contact extrusion wheel can contact the fan blades to extrude and limit the fan blades. The second contact wheel is adjusted by extending and retracting through the buffer platform, and the second contact wheel rotates on the buffer platform.

[0016] A convenient and controllable method for installing and connecting offshore wind turbines includes the following steps:

[0017] S1. First, connect the lifting plate to the lifting rope to lift the lifting connection structure, side guard frame, support base frame, fitting support plate, and reinforced base. The fan blades can be fastened through multiple sets of connecting equipment to ensure the stability of the lifting.

[0018] S2. Before use, insert the fan blades between the first contact wheel and the arc-shaped guide frame. At this time, the fan blades are in contact with the support plate. The side guard, support base, support plate, and reinforced base are fixed as a whole, which can carry out uniform load-bearing work. Then, control the hydraulic controller to pull back, which drives the hydraulic telescopic control guide rod to move upward, so that the reinforced end frame, arc-shaped guide frame, buffer platform, and second contact wheel change position. At this time, the second contact wheel contacts the fan blades and cooperates to carry the load, thereby limiting the fan blades.

[0019] S3. Subsequently, the first limiting mechanism operates. The upper end of the electro-hydraulic control rod in the first limiting mechanism is hinged to the second cooperating guide rod, and the lower end of the electro-hydraulic control rod is hinged to the first cooperating guide rod. At this time, the electro-hydraulic control rod extends, driving the movable adjustment frame to move. The movable adjustment frame rotates around the supporting cooperating rod, synchronously driving the contact pressing wheel to move around the supporting cooperating rod. The supporting cooperating rod contacts the wind turbine blades and is limited and fixed again, thereby improving the connection stability. The first contact wheel can move through the second electro-hydraulic control rod, driving the first contact wheel to move down, so that the first contact wheel contacts the upper surface of the wind turbine blades, thereby ensuring the stability of the wind turbine blades during hoisting.

[0020] S4. Finally, the wind turbine blades can be lifted by a crane. The center of the support plate is connected to the platform frame through fixed pads and hydraulic buffer seats, which can improve the buffer protection performance of the center position. The support plate is fixed to the four corners of the platform frame through positioning shaft seats, diagonal brackets and mating shafts, which can improve the structural stability of the platform frame. With the setting of hydraulic buffer seats, excess stress can be absorbed, which can reduce the problem of high-altitude swaying, thus enabling smooth lifting.

[0021] The beneficial effects of this invention are:

[0022] First, this invention features a side guard frame that is fixed to the support base, the fitting support plate, and the reinforcing base. The side guard frame, the support base, the fitting support plate, and the reinforcing base are integrally formed. The reinforcing base provides bottom support for the wind turbine blades. An adjustment component is fixedly connected to the side end of the support limiting component. The hydraulic controller within the adjustment component controls the retraction of the hydraulic telescopic control rod, causing the reinforcing end frame and the arc-shaped guide frame to change position. Once they reach the appropriate position, the buffer platform controls the extension of the second contact wheel, thereby contacting the wind turbine blades for support.

[0023] Second, the present invention facilitates upper support and limiting operations through the top-fitting mechanism, making it easy to lift the platform. The platform frame is connected to the support and stabilizing plate via fixed pads, hydraulic buffer seats, and the side end of the support and stabilizing plate can be fixed to the mating shaft via positioning shaft seats, achieving efficient support of the platform frame. The side end of the fixed rod fixes the arc frame, and the lower end of the arc frame is equipped with a first contact wheel for easy contact with the fan blades. After the limiting is completed, the electro-hydraulic control rod can extend, allowing the movable adjustment frame to rotate via the support and fitting rod, changing the position of the contact extrusion wheel. The contact extrusion wheel contacts and extrudes the fan blades, improving the load-bearing protection capacity. Furthermore, the arc frame and arc-shaped guide frame are both arc-shaped, which facilitates improved load-bearing capacity. Attached Figure Description

S2. Before use, insert the fan blades between the first contact wheel (27) and the arc-shaped guide frame (34). At this time, the fan blades are in contact with the support plate (4). The side guard (2), the support base (3), the support plate (4), and the reinforced base (5) are fixed in one piece, which can carry out uniform load-bearing work. Then, control the hydraulic controller (31) to pull back, drive the hydraulic telescopic control guide rod (32) to move up, so that the reinforced end frame (33), the arc-shaped guide frame (34), the buffer platform (35), and the second contact wheel (36) change position. At this time, the second contact wheel (36) contacts the fan blades and carries out load-bearing work, thereby limiting the fan blades. S3. After that, the first limiting mechanism (8) works. The upper end of the electro-hydraulic control rod (16) in the first limiting mechanism (8) is hinged to the second cooperating guide rod (17), and the lower end of the electro-hydraulic control rod (16) is hinged to the first cooperating guide rod (15). At this time, the electro-hydraulic control rod (16) is extended, and the movable adjustment frame (13) is driven to move through the electro-hydraulic control rod (16). At this time, the movable adjustment frame (13) rotates around the support cooperating rod (12), and synchronously drives the contact extrusion wheel (14) to move around the support cooperating rod (12). The support cooperating rod (12) contacts the wind turbine blade and is limited and fixed again, thereby improving the connection stability. The first contact wheel (27) moves through the second electro-hydraulic control rod, driving the first contact wheel (27) to move down, so that the first contact wheel (27) contacts the upper surface of the wind turbine blade, thereby ensuring the stability of the wind turbine blade during hoisting. S4. Finally, the wind turbine blades can be lifted by the crane. The center of the support plate (22) is connected to the platform frame (25) through the fixed pad (28) and the hydraulic buffer seat (29), which can improve the buffer protection performance of the center position. The support plate (22) is fixed to the four corners of the platform frame (25) through the positioning shaft seat (21), the diagonal frame (23) and the mating shaft (24), which can improve the structural stability of the platform frame (25). With the setting of the hydraulic buffer seat (29), excess stress is absorbed, which can reduce the problem of high-altitude swaying, thus enabling smooth lifting.
