Abstract
The utility model discloses appearance is peeied at in pull rod formula self -cleaning rockhole mainly comprises photoelectric probe, scalable pull rod, hand -held type display and gasbag. The PVC pipe box that scalable pull rod was 1m by length connects to be constituteed, and its length can be stretch according to the engineering needs. Photoelectric probe installs in the protective sleeve of 8 wash -out holes is evenly arranged to the inboard, and when the photoelectric probe surface adhesion drop of water or other debris, gasbag that the extrusion is connected through quick -operation joint and scalable pull rod, the air current of production arrive the wash -out hole along the gas passage, adsorbs at the drop of water on photoelectric probe surface or other debris through the recess outflow of protective sleeve afterbody under the air current acts on. The data message of being gathered by photoelectric probe arrives data line concentration ware through optic fibre. The utility model relates to a geotechnical engineering inner structure monitoring facilities, the design is exquisite reasonable, easy operation.
Description
Technical field
The utility model relates to a kind of underground geotechnical engineering internal construction monitoring instrument, and especially a kind of rod-pulling type self-cleaning rockhole endoscope, in rock body drilled internal construction monitoring technology.
Background technology
The quality of rock-mass quality particularly internal construction is directly connected to the safety in production of underground geotechnical engineering design, construction, later maintenance links, lacks and will control have a negative impact to geotechnical engineering stability to the accurate control of rock mass internal construction.Large quantifier elimination is expanded to the monitoring of rock mass internal construction both at home and abroad, basically formed with the direct monitoring that is main flow of rockhole endoscope and take CT scan as the nondestructive testing of representative.The reliability that rockhole endoscope is directly perceived with it, visual and higher occupies an important position in the monitoring of current geotechnical engineering (gas drilling, roof delamination, armature boring) internal construction, but still there are problems in actual applications.Under normal circumstances, photoelectric probe is connected with Flameproof box by optical cable, for observing the surrounding rock structure in taller and bigger depth bounds, the length of optical cable certainly will increase, the volume depositing the explosion-proof tank of optical cable increases, cause whole equipment to become abnormal heavy thereupon, inconsistent with the basic demand of underground geotechnical engineering monitoring equipment volume miniaturization, be unfavorable for onsite application.Secondly, inevitably there is trickle to a certain degree in the bore inner set in the geotechnical engineering of underground, during traditional built-in optical electric probe adsorption globule, when particularly trickle effect is serious, detecting head surface will become abnormal fuzzy, clearly cannot observe rock mass internal construction accurately, for not affecting normal use, boring is reentered into after needing artificial photoelectric probe being taken out from boring to carry out wiping, so repeatedly operate in the efficiency reducing instrument to a certain extent and use, in operating process repeatedly, easily cause the damage of photoelectric probe simultaneously.
Summary of the invention
Technical problem: the purpose of this utility model is to provide a kind of impact that can reduce to greatest extent on photoelectric probe when trickle appears in bore inner in the geotechnical engineering of underground, the rockhole endoscope of compact conformation, small volume, realizes the scientific and effective monitoring of underground geotechnical engineering rock mass internal construction.
Technical scheme: the utility model rod-pulling type self-cleaning rockhole endoscope, forms primarily of photoelectric probe, telescopic bar, hand-held display device and air bag.The pvc pipe that described telescopic bar is 1m by 8 length is nested to be formed, and pvc pipe diameter increases successively, nested layer by layer, is furnished with optical-fibre channel and gas passage respectively therein.Telescopic bar upper end is connected by internal thread with the photoelectric probe be arranged in cylindrical protective sleeve, and the data hub that lower end is installed is connected with hand-held display device by wireless transmission method.The image information that photoelectric probe gathers by the Optical Fiber Transmission in optical-fibre channel to data hub.8 clean-out openings towards photoelectric probe surface diameter 5mm are evenly arranged inside protection sleeve; when photoelectric probe surface attachment has the globule or other foreign material; the air bag that extruding telescopic bar afterbody is connected by snap joint; the air-flow produced arrives clean-out opening along gas passage; the globule or other foreign material that are attached to photoelectric probe surface are dispelled; the foreign material dispelled and the globule groove bottom protection sleeve flows out, thus reaches the object of cleaning probe.
Beneficial effect: the present invention is applied in the inner surrounding rock structure monitoring of underground geotechnical engineering, size and the weight of monitoring instrument farthest can be reduced by rod-pulling type self-cleaning rockhole endoscope, the air-flow simultaneously extruding the generation of elliposoidal air bag cleans photoelectric probe, ensure that the normal use of instrument.Rod-pulling type self-cleaning rockhole endoscope compact conformation, deft design is reasonable, simple to operate, has practicality widely, rock mass internal construction monitoring technology is simplified further in the monitoring of underground construction rock mass internal construction.

Detailed description of the invention
Below in conjunction with accompanying drawing, an embodiment of the present utility model is further described:
Shown in Fig. 1, the utility model rod-pulling type self-cleaning rockhole endoscope, comprises photoelectric probe (2), telescopic bar (4), hand-held display device (7) and air bag (5).Described telescopic bar (4) upper end is connected by internal thread (3) with the photoelectric probe (2) being placed in cylindrical protective sleeve (1) inside, and telescopic bar (4) afterbody is connected with air bag (5) by snap joint (6).Hand-held display device (7) is connected with data hub (14) by the mode of wireless transmission.
Shown in Fig. 2, cylindrical protective sleeve (1) inner homogeneous of the utility model rod-pulling type self-cleaning rockhole endoscope is furnished with the clean-out opening (8) that 8 diameters are 5mm, and being provided with at protection sleeve (1) afterbody can the groove (9) of water supply and draining.
Shown in Fig. 3, the telescopic bar (4) of the utility model rod-pulling type self-cleaning rockhole endoscope is by 8 length that the pvc pipe (10) of 1m is nested layer by layer to be formed, according to requirement of engineering stretching pvc pipe in use procedure, thus change the length of telescopic bar (4).Pvc pipe (10) internal placement has data transmission channel (11); the inside in data transmission channel (11) pasted by optical fiber (13); one end is connected with photoelectric probe (2); one end is connected with data hub (14), the clean-out opening (8) that gas passage (12) connective protection sleeve (1) is inner and air bag (5).When photoelectric probe (2) the surface attachment globule or other foreign material; the air-flow that extruding elliposoidal air bag (5) produces arrives clean-out opening (8) along gas passage (12); the globule that air-flow dispels or other foreign material flow out along the groove (9) of protection sleeve (1) afterbody, reach the object of cleaning photoelectric probe (2).
