The solar reflector is one of the core components of the trough-type medium and high temperature heat collection system, including glass mirror, ceramic mirror, metal mirror and so on. Reflectors are an important part of solar heat utilization, and high precision, high reflectivity and high durability constitute important performance indicators of solar reflectors.

Practical problems

1. The solar reflector is more than 5m long and 2.5m wide. The three-dimensional scanner equipment cannot complete the deviation of the solar reflector and the mounting hole of the bracket.
2. The solar mirror installation hole position and bracket detection work, using traditional detection methods, the detection speed is slow, and it takes a long time, which can not meet the measurement needs of the company.

Holon solutions

Case Introduction:
        For a large domestic new energy company, due to the deviation and deformation of the mounting holes between the trough solar reflector and the bracket, it is very difficult for the company’s technicians to install the solar reflector. Hualang technical engineers based on the problems faced by the company , Use Hualang 3D photogrammetry system to detect and analyze the installation holes and brackets of solar mirrors, and provide effective solutions for the company's later installation and debugging of solar mirrors.
Scanning device:
        HL-3DP three-dimensional photogrammetry system
Features:
      ●Global coded actuarial registration, suitable for measuring different objects of large, medium and small.
      ●For the 3D measurement of super large workpieces, control the overall accuracy of the workpiece and use it with a 3D scanner to reduce the cumulative error of 3D scanning data splicing.
      ●Quickly calculate the precise three-dimensional coordinates of the coding points and marking points on the surface of the workpiece.
      ●Using alloy target rod, higher stability.
