Description

Technical Field

[0001] This utility model belongs to the field of wind power transportation technology, specifically relating to a novel blade root side support. Background Art

[0002] Wind turbine blades are one of the core components of wind turbines, and their quality directly affects the performance and effectiveness of the wind turbine.

[0003] The structure of a wind turbine blade mainly includes the following parts: The outer shell, typically made of composite materials such as glass fiber reinforced resin, to ensure lightweight yet high strength. The root reinforcement layer, located at the blade root, provides additional strength and stiffness to cope with the enormous stresses generated during rotation. The web, perpendicular to the outer shell and located inside, supports the blade shell and bears bending loads; it often uses an I-beam structure to reduce weight. The spars, perpendicular to the web and located inside the outer shell, serve as the main load-bearing structure of the blade; their structure directly affects the structural strength in the flapping direction. The leading and trailing edge structures, located at bends on the outer shell surface, include a bonding area and a sandwich area at the leading edge, and a sandwich structure, reinforcement area, and bonding area at the trailing edge. These structures collectively enhance the blade's shear resistance and stiffness.

[0004] The root of a wind turbine blade is connected and fixed to the hub for rotation. During transport, a curved support is placed at the blade tip, the middle of the outer casing, and below the blade root, secured with ropes. This method is suitable for land-based operations. However, for ship transport, where blades are placed on cargo ships, this curved support is unsuitable. At sea, blades are subject to rocking from wave to wave. Placing the support only below the blade root leaves the root unsecured as it moves upwards, leading to bending, collisions, and damage that renders the blade unusable. Therefore, a new structure is needed to secure the blade root during ship transport. Summary of the Invention

[0027] The base frame 01 is made of metal tubing and has high strength and stability. The base frame 01 includes several horizontally arranged first horizontal tubes 010 and several vertically arranged first vertical tubes 011. The first horizontal tubes 010 and the first vertical tubes 011 are spliced ​​together to form a rectangular base frame. The first horizontal tubes 010 are used for horizontal connection on the horizontal plane, and the first vertical tubes 011 are used for vertical connection.

[0028] The top of the first vertical tube 011 is provided with a limiting tip 012, and the limiting tip 012 has a first through hole 0120 that penetrates the surface; the limiting tip 012 is also made of metal block; a positioning mechanism 03 is installed on the bottom frame, and the positioning mechanism 03 is used to fix the stud 05 on the blade root by screwing on the nut.

[0029] The top frame 02 is also made of metal tubing. The top frame 02 includes several horizontally arranged second horizontal tubes 020 and several vertically arranged second vertical tubes 021. The second horizontal tubes 020 and the second vertical tubes 021 are spliced ​​together to form a rectangular top frame. The bottom surface of the second vertical tube 021 is provided with a first limiting hole 0210, and the side wall of the second vertical tube 021 is provided with a through second through hole 0211. A positioning mechanism 03 is installed on the top frame. The positioning mechanism 03 is used for the studs 05 on the blade root to pass through and be screwed on with nuts for fixation. The second horizontal tubes 020 and the second vertical tubes 021 are also spliced ​​together to form a rectangular frame.

[0030] The top frame 02 is stacked on the base frame 01, and the limiting point 012 is inserted into the first limiting hole 0210. The pin 04 passes through the second through hole 0211 and the first through hole 0120 for connection and fixation. This achieves a detachable connection, facilitating assembly and transportation.

[0031] As described above, in the specific usage process, the base frame 01 is placed on the cargo ship, the top frame 02 is placed on the base frame 01, the limiting pin 012 is inserted into the second vertical tube 021, and the pin 04 passes through the second vertical tube 021 and the limiting pin 012 for fixation, thereby achieving connection and fixation; then the studs 05 on the blade root pass through the positioning mechanisms 03 on the base frame 01 and the top frame 02 respectively, and then the nuts are screwed on for fixation; the bolts pass through the base frame 01 and are fixed on the cargo ship.

[0032] The base frame 01 and the top frame 02 are spliced ​​together to form a large rectangular frame, which fixes the studs 05 on the blade root, that is, fixes the sides of the blade root from top to bottom, thus preventing the blade root from being damaged by collisions when it is rocked at sea.

[0033] Furthermore, several short first horizontal pipes 010 are welded between the two long first horizontal pipes 010, and two first vertical pipes 011 are welded to the front and rear ends of the bottom frame respectively, and two first vertical pipes 011 are welded to the left and right ends of the bottom frame.

[0034] According to design requirements, the first horizontal tube 010 and the first vertical tube 011, of varying lengths, are welded and fixed together. Figure 2As shown; two first vertical tubes 011 are respectively set on the left, center and right of the bottom frame, which have better support and bearing capacity, and will inevitably be crushed by the top frame 02;

[0035] The top of the limiting tip 012 is conical, and the bottom of the limiting tip 012 is provided with a threaded post 0121; the top of the limiting tip 012 facilitates the insertion of the second vertical tube 021.

[0036] It also includes a first pad 013, on which a third through hole 0600130 is provided. A threaded post 0121 passes through the third through hole 0600131 and is fixed by screwing on a nut. The first pad is welded to the first vertical pipe 011 for fixation.

[0038] As described above, in the specific assembly process, the threaded post 0121 of the limiting tip 012 passes through the first pad 013 and is fixed with a nut. Then, the first pad 013 is welded onto the first vertical tube 011. If the limiting tip 012 is damaged, the first pad 013 is cut and replaced.

[0039] Furthermore, a first support plate 014 with an arc-shaped upper surface is welded to the first horizontal tube 010 at both ends of the bottom frame, and a second support plate 015 with an arc shape is welded between the two first support plates 014.

[0040] As mentioned above, the second support plate 015 is used to support the leaf root, which serves to limit and support, making it more stable;

[0041] Furthermore, a triangular first reinforcing plate 0140 is welded between the first support plate 014 and the second support plate 015.

[0042] As mentioned above, the second support plate 015 is more robust, less prone to being crushed, and has a longer service life.

[0043] Furthermore, the positioning mechanism 03 includes two opposing first plates 030, and a number of through first round tubes 031 are welded between the two first plates 030, and the number of first round tubes 031 are arranged in an arc shape.

At the same time, several first circular tubes 031 are arranged in an arc shape to fit the studs 05 of the blade root.

[0047] Furthermore, it also includes a buffer block 06, which has several third through holes 0600130. Bolts pass through the buffer pad and are connected to the first plate 030. The third through holes 0600130 correspond to the first round tube 031.

[0048] As described above, the buffer pad is supported by an elastic rubber block in order to prevent damage to the stud 05 when it is inserted into the first round tube 031.

[0049] Preferably, an arc-shaped long strip washer is added. The stud 05 passes through the first round tube 031, passes through the long strip washer, and is screwed on with a nut. The long strip washer plays a clamping and fixing role to prevent the stud 05 from shaking.

[0050] Furthermore, two forklift pipes 0110 are welded onto the first vertical pipe 011 and the second vertical pipe 021.

[0051] As described above, the forklift tube 0110 is a metal square tube, welded to the first vertical tube 011 and the second vertical tube 021, for the insertion of the forklift's forks to facilitate transportation.
