b. a directional WIFI receiving wire interface (23) and an emergency rope connecting post (24) at the bottom of the peeping probe are connected with a directional WIFI receiving wire (28) and an emergency rope (27) with a length label attached in a meter unit, firstly, a group of rocker arms (4) at the upper part of a peeping probe main body (1) are loosened, a rocker arm locking block (6) at the side surface of a side wall groove (5) is pushed to be unlocked with a rocker arm locking hole (7), then, the rocker arms (4) are released, a group of rocker arms (4) at the upper part of the peeping probe main body (1) are pressed and contracted, then, the peeping probe is pushed into a drill hole (25), a group of rocker arms (4) at the front part of the drill hole (25) slowly expand outwards under the double actions of a torsion spring (12) and a gas spring (16), the rocker arms (4) abut against the side wall around the drill hole (25), and then, a group of rocker arms (4) at the lower part, the rocker arm locking block (6) is pushed to release the rocker arm (4) in the same way as the rocker arms in the groups, the rocker arm (4) is pushed and then pushed into the drill hole (25), the action of the rocker arms in the rear group entering the drill hole (25) is the same as that of the rocker arms in the front group, and the rocker arms in the rear group and the rocker arms in the front group are supported and abutted against the side wall around the drill hole (25) in a cross manner;
c. continuously pushing the peeping probe into the drill hole (25), fixing and orienting a WIFI transmitting line (29) at a position 5-10 cm away from the hole opening of the drill hole (25) by using an adhesive tape, enabling the WIFI transmitting line to cling to the inner wall of the drill hole (25), connecting the other end of the WIFI transmitting line (29) with an operation host (30), and controlling and monitoring the working state of the peeping probe main body (1) through the operation host (30);
d. the electronic control signal is transmitted by controlling a directional WIFI receiving line (28) and a directional WIFI transmitting line (29) between a host (30) and a peeping probe body (1), the receiving end is the peeping probe body (1), the transmission path is the directional WIFI receiving line (28), the transmitting end is the control host (30), and the transmission path is the directional WIFI transmitting line (29); the peeping probe main body (1) collects signals and stores a peeping video, and a length label attached to the emergency rope (27) in a meter unit is referred to, and the forward distance of the peeping probe displayed by an operating personnel handheld control host (30) is compared and checked;
e. when the peeping probe moves forwards and meets a rock stratum crushing area, the peeping probe body (1) moves forwards or backwards by operating the host (30) and matching with the emergency rope (27), and the peeping probe body (1) can move backwards quickly by pulling the emergency rope (27);
f. when the peeping probe encounters an area with the diameter increased by a drill hole (25) in the advancing process, the rocker arm (4) expands under the dual actions of the torsion spring (12) and the gas spring (16), when the probe expands to the maximum angle, the rocker arm end detection contact piece (10) is connected with the probe body end detection contact piece (11), a warning signal is fed back, a directional WIFI transmission line (29) is transmitted to the handheld control host (30), and an operator takes measures immediately;
g. when the diameter of the peeping probe is reduced due to the deformation of the drill hole (25) in the advancing process, the rocker arm (4) contracts and presses the torsion spring (12) and the gas spring (16), so that the overall effective diameter of the peeping probe is reduced, and the peeping probe is adapted to a deformed drill hole area and passes through the area.
9. The peeking method of claim 8 using the self-propelled peeking probe of claim 1 adapted for different borehole diameters, wherein: in the serious broken region of drilling (25), when peeping probe main part (1) because cracked rock leads to the card phenomenon to take place, pulling and adjusting emergent rope (27), make rocking arm (4) retract towards the direction of recess (5), can avoid taking place to peep the unable condition emergence of rolling back of probe main part (1).
