Including cantilever 2, detection box 3, probe 4 and hydraulic cylinder, cantilever 2 end is located at by detection box 3,
Hydraulic cylinder is located in detection box 3, and probe 4 is located on the outer face of piston 7, and probe 4 is with alive
The axis of plug 7 is parallel.Preferably, when hydraulic cylinder does not works, probe 4 is also in detection
In box 3, when hydraulic cylinder is started working, probe 4 just removes from detection box.Further,
Detection device also includes that controller 6, hydraulic cylinder electrically connect with controller 6.Preferably, piston
7 or probe 4 be provided with displacement transducer, displacement transducer electrically connects with controller 6, passes through
The degree of depth of the displacement of probe 4, i.e. sediment known by displacement transducer.
Further, described cantilever 2 is scalable, it is preferred that cantilever 2 is level Four telescopic arm；
Cantilever 2 can also be telescoping hydraulic cylinder, further, and cantilever 2 top and the steel of unwheeling 1
Twisted wire be connected, steel strand wires with drive on hook be connected, detect device move with unwheeling 1.Frame
Car 1 may select winch.
During use, after borehole and clinkerer complete, by driving 1 by this utility model dress
Put and move to aperture, slowly put down cantilever 2, when probe 4 bottom arrives sediment surface, stop
Transferring cantilever 2, hydraulic cylinder is started working, and hydraulic cylinder drives piston 7 to move down with constant force,
Probe 4 moves down with piston 7, when probe 4 arrives at the bottom of hole, due to the active force at the bottom of hole
More than the thrust of the piston 7 of hydraulic cylinder, piston 7 stops mobile, reads the displacement of probe, this
Individual displacement is i.e. the degree of depth of sediment.The displacement of probe can be read by arranging scale on probe
Take, it is also possible to measure distance by ultrasonic unit.
Embodiment 2
As shown in Figure 3,4, the present embodiment is with the difference of embodiment 1: controller 6 wraps
Including display screen, detection box 3 side is mounted with minisize pick-up head 5, minisize pick-up head 5 and detection
Box 3 bottom surface is in same level, and minisize pick-up head 5 electrically connects with controller 6.Display screen
Minisize pick-up head finding picture can be shown, it is judged that whether device front end arrives sediment surface.Use
In and read the probe test degree of depth.
During use, after borehole and clinkerer complete, by driving 1 by this utility model dress
Put and move to aperture, slowly put down cantilever 2, observed by display screen, when probe 4 bottom arrives
During sediment surface, stopping transferring cantilever 2, hydraulic cylinder is started working, and hydraulic cylinder drives with constant force
Piston 7 moves down, and probe 4 moves down with piston 7, when probe 4 arrives at the bottom of hole,
Owing to the active force at the bottom of hole stops mobile more than the thrust of the piston 7 of hydraulic cylinder, piston 7, position
Displacement sensor measures the displacement of probe, and this displacement is i.e. the degree of depth of sediment.
