Description

Technical Field

[0001] The present invention relates to the field of unmanned aerial vehicles (UAVs), and in particular to an unmanned aerial vehicle (UAV) for detecting thermal performance defects of enclosure structures. Background Art

[0002] The enclosure structure refers to the enclosures on all sides of buildings and rooms, which are divided into two types: transparent and opaque. After the existing enclosure structure is produced, it is necessary to use a detection device to test the thermal performance of the enclosure structure. Thermal performance refers to the thermophysical properties of materials, such as thermal conductivity, thermodynamic efficiency, etc. It is the abbreviation of engineering thermodynamics and heat transfer. Generally, the existing enclosure structures are often set in a closed thermal environment when conducting thermal performance tests. When conducting tests in a closed environment, it is often difficult for users to enter the closed environment for real-time testing due to the high temperature environment. Therefore, drones used for thermal performance defect detection of enclosure structures came into being, and are gradually valued by staff.

[0003] For example, the Chinese authorized patent with announcement number CN203385687U (a wireless detector for thermal performance of enclosure structure): includes a data acquisition module for collecting thermal performance signals, and the detector also includes: a transmitting terminal connected to the data acquisition module, which outputs corresponding thermal performance data according to the thermal performance signal; a receiving terminal wirelessly connected to the transmitting terminal to receive the thermal performance data; and a control module connected to the receiving terminal, which reads the thermal performance data and controls an LED data display module to display the thermal performance data;

[0004] Although the above-mentioned existing technology has the advantage of effectively reducing the materials used in thermal performance testing when in use, when performing thermal performance testing on enclosure structures, it is often difficult for the testing mechanism to be closely attached to the enclosure structure to be tested because most drones are hovering structures, which can easily affect the detection accuracy of the entire testing mechanism. Therefore, the market urgently needs to develop a drone for thermal performance defect detection of enclosure structures to help people solve existing problems. Summary of the invention
