[0002] Currently, the installed capacity of wind power units in the new energy market is getting larger and larger, and the requirements for the design and installation precision of wind turbines are getting higher and higher. In order to ensure that there is no risk of falling objects around the tower base platform and to meet the requirements of the accuracy and aesthetics of accessory installation, the gap between the tower base platform and the tower is generally about 5-10mm. Therefore, the installation process of the tower base platform requires accurate cross-line layout. In the current wind turbine installation process, steel wire is only tied to the bolts for layout. The steel wire is relatively loose and cannot accurately locate the center of the bolt. As a result, the tower often interferes with the platform after installation and cannot be positioned. The problem of secondary platform installation and alignment is often encountered, which is time-consuming, labor-intensive and affects the construction progress. Summary of the Invention

[0003] This utility model aims to solve the problems in the prior art where insufficient installation accuracy of the wind turbine tower base platform, electrical cabinet, and ventilation equipment accessories causes interference between the bottom section of the tower and the platform, preventing them from being positioned properly and requiring secondary hoisting and alignment of the platform. Insufficient installation accuracy of other equipment accessories also results in unsightly equipment installations that fail to meet design requirements. Therefore, this utility model provides a wind turbine accessory installation and positioning device.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a wind turbine accessory installation and positioning device, comprising four sets of positioning components arranged in a cross shape. Each set of positioning components includes a foundation anchor bolt nut sleeve, a positioning support, a positioning fastening pin, a fastening lever, and a support locking rod. The positioning support is fixed to the top of the foundation anchor bolt nut sleeve. The positioning fastening pin is rotatably connected to the positioning support. A groove is formed on the shaft of the positioning fastening pin, the center of which corresponds to the center of the foundation anchor bolt nut sleeve. A through-hole is provided in the groove, through which two steel wires pass. Two steel wires cross in a cross shape and pass through the corresponding through-holes. The end of the positioning fastening pin protrudes from the positioning support. The fastening lever passes through the end of the positioning fastening pin and drives the positioning fastening pin to rotate to tighten the steel wires. The support locking rod is installed at the lower end of the fastening lever. The fastening lever is fixed to the foundation platform by the support locking rod at an angle.

[0005] Specifically, the width of the groove is 3mm.

[0006] Specifically, the diameter of the thread hole is 3mm.

[0007] Specifically, the positioning support is inverted U-shaped, and the two side plates of the positioning support are provided with pin holes, and the positioning and fastening pins are rotatably connected in the pin holes.

[0008] Specifically, the support locking rod is sleeved on the fastening lever arm, and the outside of the support locking rod is provided with an anti-slip sleeve.

[0009] Specifically, the end of the positioning and fastening pin is provided with a lever arm through hole, through which the fastening lever arm passes.

[0010] The beneficial effects of this utility model are: This utility model is convenient to install and dismantle on site, and is suitable for cross-positioning before the installation of all types of wind turbine tower accessories, so that the platform, electrical cabinet and ventilation equipment accessories can be installed in one go, avoiding rework due to installation accuracy issues, saving time and effort, improving construction efficiency, and increasing the accuracy and aesthetics of the installation process of platform, electrical cabinet and ventilation equipment accessories, reducing the manpower and material resources required for subsequent wind turbine troubleshooting.

[0017] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] like Figures 1-5 As shown, a wind turbine accessory installation and positioning device includes four sets of positioning components arranged in a cross shape. Each set of positioning components includes a foundation anchor bolt nut sleeve 1, a positioning support 2, a positioning fastening pin 3, a fastening lever 4, and a support locking rod 5. The positioning support 2 is fixed to the top of the foundation anchor bolt nut sleeve 1, and the positioning fastening pin 3 is rotatably connected to the positioning support 2. The positioning support 2 is inverted U-shaped, and pin holes 8 are provided on both side plates of the positioning support 2. The positioning fastening pin 3 is rotatably connected in the pin holes 8.

[0020] A groove 6 is provided on the shaft of the positioning fastening pin 3. The center of the groove 6 corresponds to the center of the foundation anchor nut sleeve 1. A wire hole 7 is provided in the groove 6, which passes through the center of the groove 6. The width of the groove 6 is 3mm and the diameter of the wire hole 7 is 3mm. Two steel wires are crossed in a cross shape and passed through the corresponding wire holes 7 respectively.

[0021] The end of the positioning fastening pin 3 extends out of the positioning support 2. The fastening lever 4 passes through the end of the positioning fastening pin 3 and drives the positioning fastening pin 3 to rotate to tighten the steel wire. The end of the positioning fastening pin 3 is provided with a lever through hole 9. The fastening lever 4 passes through the lever through hole 9. The support locking rod 5 is installed at the lower end of the fastening lever 4. The fastening lever 4 is fixed to the foundation platform by the support locking rod 5 at an angle. The support locking rod 5 is sleeved on the fastening lever 4, and the outside of the support locking rod 5 is provided with an anti-slip sleeve.

[0022] The working principle of this utility model is as follows: Before use, confirm the positions of the foundation anchor bolts in four directions of the fan, and install two nuts on each foundation anchor bolt. Put the foundation anchor bolt nut sleeve 1 on the nut, adjust the direction of the positioning fastening pin 3 so that the wire grooves 6 on the two opposite positioning fastening pins 3 are aligned, thread the steel wire through the wire hole 7 and wind it in the wire groove 6. After confirming that there is no error, pre-tighten the steel wire and fix it firmly. Use the fastening lever 4 to rotate the positioning fastening pin 3 to straighten the steel wire. Then install the support locking rod 5 on the lower side of the fastening lever 4 and fix it on the foundation platform by locking it with the support locking rod 5. At this time, the cross positioning steel wire is pulled on the foundation platform to facilitate the installation of fan accessories. By using this utility model, the installation accuracy of accessories such as wind turbine platforms, electrical cabinets, and ventilation devices can be increased, avoiding the problem of interference between the bottom section of the wind turbine tower and the platform due to inaccurate positioning, and the need for rework in secondary positioning and installation. This can save mechanical construction time and personnel input. At the same time, the installation quality of accessories such as wind turbine platforms, electrical cabinets, and ventilation devices is high and aesthetically pleasing, reducing the rectification work in the wind turbine troubleshooting process.
