Novel assembly wind power tower drum verticality detection device and detection method

Abstract

The invention discloses a novel assembly type wind power tower cylinder verticality detection device and detection method. The device comprises a connecting part, a laser emitter and a coordinate plate. The connecting part is installed on the outer wall of the upper end of the wind power tower barrel and is parallel to the ground. The laser emitter is mounted on the connecting part; the included angle between the laser beam emitted by the laser emitter and the ground is recorded as sigma, the included angle between the outer wall of the wind power tower and the ground is recorded as lambda, wherein sigma is equal to lambda; a magnet is attached to the center of the bottom of the coordinate plate; an XOY coordinate system is arranged on the surface of the coordinate plate, scales are arranged in the X-axis direction and the Y-axis direction, and positioning lines parallel to the X axis and the Y axis are arranged in the XOY coordinate system at intervals; during detection, the coordinate plate is fixedly connected to the ground at the position corresponding to the laser emitter; according to the invention, the mode of combining laser and the coordinate plate is adopted, so the measurement result accuracy is high, the measurement speed is high, and the reading is fast.

Description

technical field [0001] The invention belongs to the technical field of measuring devices, and in particular relates to a novel assembly-type wind power tower perpendicularity detection device and detection method. Background technique [0002] With the increasingly prominent energy and environmental issues, more and more targets are being invested in renewable energy around the world. Among them, wind energy, as an important category of renewable energy due to its own advantages, has become the most large-scale development condition and commercial The renewable energy power generation method with the prospect of globalization development, and the corresponding prefabricated wind power tower are also being vigorously promoted and used. [0003] Long-term reciprocating cyclic loads and external forces during the operation of wind power towers may cause the foundation to become loose, and the tower body to tilt or bend from top to bottom, which may eventually lead to abnormal o...

AI Technical Summary

Problems solved by technology

[0004] 1) When measuring instruments such as total stations and theodolites, the installation and disassembly process takes a long time and the work efficiency is relatively low

[0005] 2) Measurement instruments such as total stations and theodolites are relatively large in size and mass, the layout of wind power towers is relatively scattered, and the traffic conditions between wind power towers are poor. Therefore, it is difficult to transport and carry measuring instruments such as total stations and theodolites

Therefore, the use of this method requires high professionalism of personnel, and it is difficult to detect in time in engineering

[0007] 4) The detection method combining the laser device and the electronic receiving device needs to be calculated and analyzed by the electronic receiving device to obtain the deflection of the tower tube. The device is complex and takes a long time to run

[0008] 5) Traditional manual detection methods are inefficient

In the process of surveying and mapping, it is greatly affected by the external environment, the labor cost is high, and there are potential safety hazards
