Description

A surveying instrument positioning device suitable for high-altitude occasions

technical field

The invention relates to the field of surveying instrument installation, in particular to a surveying instrument positioning device suitable for high-altitude occasions.

Background technique

In order to evaluate the thermal insulation performance of high-rise building curtain wall glass and new building materials, it is an essential item to test the heat transfer coefficient of materials. Among them, when testing the heat transfer coefficient of materials, it is necessary to test the wind speed and temperature of the outer wall. At present, it is difficult to install the wind speed tester to keep the probe at a sufficient distance from the outer wall when testing the wind speed of the outer wall. Generally, the wind speed tester is only bundled. On the edge of the window, this causes the wind speed tested by the anemometer to be only the wind speed of the boundary layer of the outer wall, rather than the real wind speed blown to the glass and the outer wall, and the accuracy of the test data cannot be guaranteed.
