The invention discloses a multi-stage early warning method for geological disasters in urban underground space, and belongs to the technical field of early warning of geological disasters. Through the arrangement of a rain baffle and a hydrophobic layer, a rain shielding effect is achieved. When wind blows, movable heating balls are blown to collide and rub with one another to generate heat, and the heat enters a transverse cylinder, so that a deformation memory spring is heated to deform and starts to slowly extend to push a piston and a push rod to move, and therefore, an adsorption rubber mat is pushed to be in contact adsorption with a protective fence, and the supporting stability is enhanced. A monitoring device body generates heat during working, surrounding air expands due to heating and flows upwards, and hot air flows into a water storage barrel, so that water is heated and vaporized to form water vapor, a large amount of heat is absorbed, hot air flowing is accelerated, fan blades are driven to rot
