As shown in fig. 1, 2 and 5, under the action of conveying hydraulic oil inside the core cylinder 5 and the inner cylinder 2, the hydraulic oil enters the annular groove 29 through the first passage 25, and the hydraulic oil applies pressure to the seal ring 30, so that the seal ring 30 increases the pressure on the outer side wall of the core cylinder 5, thereby improving the sealing property between the inner cylinder 2 and the core cylinder 5, avoiding the phenomenon of oil leakage between the core cylinder 5 and the inner cylinder 2 when the hydraulic oil inside the core cylinder 5 and the inner cylinder 2 has higher pressure, and contributing to improving the working stability of the whole device.
In the process that the inner cylinder 2 pushes the equipment cylinder 11 to move towards the inside of the anchor rod hole, when a hole blocking situation is met, the motor 10 is started to work, the motor 10 drives the gear ring I12 to rotate through the gear 15, so that the gear ring I12 synchronously drives the rotary ring 13 to rotate, the rotation of the rotary ring 13 applies thrust to each sliding rod 23 through the wavy side edge of the rotary ring, and under the matching action of the spring 24, the sliding rod 23 drives the hammer head 22 to hammer foreign matters blocked in the anchor rod hole, so that the anchor rod hole is acted, the scraper 14 is synchronously driven to rotate by the rotation of the gear ring I12, bulges and the like on the inner wall of the anchor rod hole are scraped, so that the accidents that the measurement error is large and the analysis result is influenced due to the fact that the blocked foreign matters mistakenly arrive at the bottom of the anchor rod hole are avoided, and the gear ring II 17 is synchronously driven to rotate while the gear ring I12 is driven to rotate by the gear 15, thereby make ring gear two 17 drive the rotary drum 18 in step and rotate, and then make rotary drum 18 drive impeller 20 and rotate, make impeller 20 carry the air in the rotary drum 18 to nozzle 19, and then make the interior suction power that produces of rotary drum 18, this suction power passes through trachea one 3 with outside air in filter tip 7's filtration gets into rotary drum 18, wherein trachea one 3 adopts the steel wire pipe, both had soft flexible characteristic, it can avoid being shriveled by the pressure of hydraulic oil to have, thereby make rotary drum 18 can reliable and stable transport air at the pivoted in-process, the air of carrying to nozzle 19 spouts to the inside in anchor rod hole, thereby blow away the sediment bits of gathering at the bottom of hole, avoid appearing the collection sediment phenomenon, thereby further improvement is to anchor rod hole depth measurement's precision.
After the measurement is finished, the hydraulic pump is started to work, so that the hydraulic pump pumps out the hydraulic oil in the core barrel 5 and the hydraulic oil in the inner barrel 2 through the liquid pipe 6, the inner barrel 2 moves towards the inside of the outer barrel 1, the open end of the inner barrel 2 faces the air in the space to be compressed, the conduction direction of the one-way valve I9 points to the space, the conduction direction of the one-way valve II 27 points to the channel II 26, so that the compressed air in the space is blown to the outer side edge of the inner barrel 2 through the channel II 26, the baffle 28 is opened under the action of the air flow, the channel II 26 is not blocked, the dust adhered to the outer peripheral wall of the inner barrel 2 is blown away by the air flow, the inner barrel 2 is prevented from being blocked in the outer barrel 1 when the inner barrel 2 enters the outer barrel 1, the inner barrel 2 can run smoothly in the outer barrel 1, and the inner barrel 2 can not move smoothly when the inner barrel 2 does not move or move towards the outside of the outer barrel 1, the baffle 28 seals the port of the second channel 26 under the action of the coil spring, so that external dust and impurities are prevented from entering the second channel 26, and the second channel 26 is ensured not to be blocked.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
