[0002] With the development of science and technology, the standardization of construction projects is becoming more and more stringent. Levels are often needed in construction projects. Levels are instruments that establish a horizontal line of sight to measure the height difference between two points on the ground. Their principle is to measure the height difference between ground points according to the principle of leveling. Their main components include a telescope, a tube level, a vertical axis, a base, a foot screw, etc.

[0003] At present, in the existing level instrument, in addition to the operation error and instrument error, the error caused by the environment is also an important factor affecting the final observation result during the measurement process. For example, when encountering rainy days or strong sunlight outdoors, especially in rainy weather, rainwater seeping into the instrument will affect the instrument. At the same time, long-term rain will reduce the life of the level instrument, and strong sunlight will cause the surface temperature of the level instrument to rise due to the sun's exposure, affecting the accuracy of the instrument.
