Abstract
A casing pipe extends in a vertical direction, and two adjacent casing pipes are connected by a plurality of link mechanisms; the link mechanism includes two supports, the two supports are hinged by a first pin to form a hinged portion, an upper end and a lower end of the link mechanism are hinged to two adjacent casing pipes by second pins separately, a sensor is fixed to the link mechanism, and the link mechanism has an initial state of extending in the vertical direction and an extending state in which the hinged portion extends outwards to be located on an outer side of the casing pipe; a driving mechanism drives a push portion to move towards the link mechanism; and a downward pressing apparatus is used for pressing a top end of the topmost casing pipe downwards to push the hinged portion into a side wall of the borehole.
