Be out of shape for present landslide depth the present situation that large displacement can't be monitored, intend adopting high precision inclination sensor and photoelectric encoder to combine, by independent development and the system integration, research can be followed the tracks of sliding real-time monitoring system and field installation process with large change in displacement, landslide elastic deformation stage, fine fisssure deformation stage and the high precision monitor of deformation stage had at the uniform velocity both been solved, can follow the tracks of again that deformation stage is accelerated on the landslide and acute sliding deformation stage cunning is with large change in displacement, for analysis of landslide body real-time deformation process and monitoring and warning provide reliable full and accurate foundation.
Further, the center of described take-up and the center of fixed leg are provided with pin, and the bottom of pin is fixed on the monitoring case, and take-up and fixed leg all can rotate around pin separately.Wire rope on take-up is some circles, tightens up or during unwrapping wire, take-up all will rotate at needs, by scroll spring, drives fixed leg and rotates, and bearing pin is set, and is convenient to exactly the synchronous rotation of take-up and fixed leg.
Further, described flexible rope is wire rope, and spring is scroll spring, and wire rope is arranged on the top of scroll spring.Adopt wire rope and scroll spring to be optimal way, satisfy service condition as long as can provide, scroll spring has another name called clockwork spring, and the one end is fixed and other end effect has moment of torsion; In the distortion of the torsional interaction lower spring material production elasticity of flexure, make spring planar produce torsion, its size of being out of shape the angle is directly proportional to moment of torsion.
Further, described photoelectric encoder is connected with runner, and runner and photoelectric encoder are connected to one-piece construction, and one-piece construction can be rotated along the axial line of runner, and the wheel face indent of runner forms groove, and wirerope-winding is in groove.Wirerope-winding is a circle in groove, utilizes the motion of wire rope to drive the rotation of runner, and photoelectric encoder utilizes the number of turns that runner rotates and girth etc. to calculate the distance that wire rope moves.
In sum, the beneficial effects of the utility model are:
(a) traditional landslide displacement distortion relies on borehole inclinometer to complete, the restriction but borehole inclinometer takes measurement of an angle, when Landslide Deformation larger, when exceeding the dipmeter survey scope, borehole inclinometer lost efficacy, and still can react the deformation on landslide by the length variations of the wire rope that employing flexibly connects this moment;
(b) propose to install the flexible displacement monitors of many groups in same boring, the length variations of the wire rope by different depth position, each degree of depth deformation of analysis of landslide, and then landslide bulk deformation situation is analyzed.
