The invention provides a navigation antenna retracting device and an inspection unmanned aerial vehicle device. The navigation antenna retracting device comprises a box body, a signal detector, a lifting box, an antenna, a first driving device and a second driving device, the lifting box movably penetrates through the penetrating opening of the box body and is connected with the first driving device; the second driving device is arranged in the lifting box and is connected with the antenna; the signal detector detects a navigation signal received by the unmanned aerial vehicle; when the intensity of the navigation signal is smaller than the preset intensity, the controller controls the first driving device to drive the lifting box to move towards the top of the box body and controls the second driving device to drive the antenna to move towards the top of the lifting box; and when the navigation signal is greater than or equal to the preset intensity, controlling the first driving device to drive the lifting box to move towards the bottom of the box body, and controlling the second driving device to drive the antenna to move towards the bottom of the lifting box. According to the invention, navigation signals can be received to the greatest extent, automatic contraction of the antenna is realized, antenna damage is avoided, and safe use of the unmanned aerial vehicle is ensured.
