This invention discloses a device for wireless communication between underground manholes and the ground, relating to the field of urban underground infrastructure monitoring technology. It solves the problem that manhole covers and frames are mostly made of metal, which strongly shields electromagnetic waves, affecting data acquisition by monitoring equipment inside the manhole. The key technical points include: a manhole frame support: an open-frame structure adapted to the manhole cover; an adjustment component on the support to adjust the diameter of the support to accommodate differences in the manhole cover's diameter; and an equipment support: located on the support, forming a downwardly protruding load-bearing structure. The effect is that by fixing the transmitting antenna in the gap between the manhole cover and frame, the electromagnetic shielding effect of the cover and frame is avoided, significantly enhancing signal strength compared to inside the manhole, ensuring normal data communication between the monitoring equipment inside the manhole and the ground.
