Probe vehicle for pavement depression detection and temporary shielding

The invention discloses a probe vehicle for pavement depression detection and temporary shielding. The probe vehicle comprises a placement block, a placement cavity with a downward opening is formed in the placement block; a blocking mechanism is arranged in the placement cavity; the blocking mechanism comprises an induction fixing block fixedly connected with the inner wall of the rear side of the placement cavity. An induction sliding cavity with a downward opening is formed in the induction fixing block. The inner wall of the upper side of the induction sliding cavity is fixedly connected with an induction extension spring; an induction sliding block in sliding connection is arranged in the induction sliding cavity; and the induction sliding block is fixedly connected with the inductionextension spring. According to the device, the road surface can be detected, when the road surface is sunken, a machine can be started, a temporary shielding effect is achieved by placing a shieldingplate on the road surface
