The invention discloses an underground water level observation device for hydrogeological exploration, which comprises a detection head, a lower-section protective shell, a filter screen, a rotating ring and a scraper, and is characterized in that the rotating ring is driven by a driving mechanism to rotate on the lower-section protective shell; the pressure applying piece is arranged between the lower-section protective shell and the scraping plate and keeps rotating along with the rotating ring, and the scraping plate is extruded by the pressure applying piece to be attached to the outer wall of the filter screen all the time. According to the underground water level observation device for hydrogeological exploration provided by the invention, the rotating ring keeps rotating through the driving mechanism, and the scraping plate on the rotating ring can keep rotating on the outer wall of the lower-section protective shell, so that viscous objects attached to the filter screen are scraped, viscous solids att
