AI Technical Summary

Technical Problem

In high humidity environments, condensation can easily form on the surface of the search and rescue drone's camera, resulting in unclear images and affecting the search and rescue effectiveness.

Method used

The camera is protected by a hemispherical protective cover, and a thermoelectric cooling chip is installed inside it. The inside of the protective cover is heated to prevent condensation. At the same time, protruding columns and heat sinks are used to accelerate the dissipation of cold energy at the cold end. An arc frame and sponge strips are used to clean the surface of the protective cover to remove moisture and foreign objects.

Benefits of technology

It effectively prevents condensation on the camera, ensures clear imaging, improves search and rescue efficiency, and extends the service life of the equipment.

Abstract

This utility model relates to the field of drone search and rescue technology, specifically to a search and rescue drone, including a drone body. A fixing plate is installed at the bottom center of the drone body, and an annular plate is installed at the bottom of the fixing plate. A hemispherical protective cover is fixed to the bottom of the annular plate. The protective cover is transparent. A camera module is installed on the fixing plate inside the protective cover, with the camera module facing downwards. A thermoelectric cooling element is installed on the fixing plate inside the protective cover, offset from the camera module, with the hot end of the thermoelectric cooling element facing the inside of the protective cover. This utility model uses a protective cover to isolate the search and rescue camera module, and then uses a thermoelectric cooling element to heat the inside of the protective cover. By raising the temperature of the protective cover, it is brought above the dew point temperature, thereby preventing moisture condensation in high humidity environments from affecting the imaging of the camera module.
