Description

Technical Field

[0001] The utility model relates to the technical field of forestry detection, in particular to an adjustable infrared thermal imager for forestry. Background Art

[0002] Infrared thermal imagers are often used for forest fire detection. Existing infrared thermal imagers used for forest fire monitoring are mostly fixedly installed and cannot be adjusted according to needs. In order to improve the above shortcomings, adjustable thermal imagers have emerged.

[0003] The prior art discloses an adjustable infrared thermal imager for forest fire identification and detection (publication number: CN212482708U), which includes a shell, a support base installed on the top of the shell, a mounting slot provided on the top of the support base, a motor 1 installed inside the mounting slot, a rotating plate installed on the top of the motor 1, and the top of the rotating plate extends to above the top of the support base, a fixed plate symmetrically installed on the top of the rotating plate, and adjusting bolts are installed through the fixed plates, and the ends of the adjusting bolts close to each other are installed with shaft seats, and the sides of the shaft seats close to each other are installed with fixing frames, and the infrared thermal imager body is installed between the fixing frames.

[0004] In the existing technology, multi-position adjustment of thermal imagers is achieved through multiple motor drives. For forest protection, point-to-point monitoring is mostly adopted, that is, one thermal imager is responsible for monitoring an area. Although multi-motor adjustment of thermal imagers can flexibly adjust the monitoring position, it also increases the subsequent maintenance and usage costs. For usage scenarios where repeated position adjustment is not required after forest debugging is completed, the multi-motor position adjustment method is somewhat unreasonable.

[0005] To this end, we propose an adjustable infrared thermal imager for forestry use. Utility Model Content
