Technical field
The present invention relates to special equipment field, specifically a kind of pressure pipeline detects intelligent sphere from drifting type ultrasound.
Background technique
Pressure pipeline cause of accident mainly has burn into welding and fault in material, equipment fault, operation against rules and external force to destroy
Deng.Accident caused by wherein burn into welding and fault in material rupture occupies very big ratio.Therefore pressure pipeline every
The defects of some cycles should carry out periodic inspection, burn into crackle to detect pressure pipeline eliminates accident in budding state.
Pressure pipeline mostly uses the detection of the technologies such as Magnetic Flux Leakage Inspecting, ultrasound detection, EDDY CURRENT, vision-based detection progress defect
With security evaluation.However, these methods are only applicable to the outer detection of pressure pipeline, for the buried pipeline of depths underground, by it
The limitation of running environment, pumped (conveying) medium has larger difficulty from pipeline external detection corrosion, even if using not excavating, not influencing just
The outer detection mode often to work detects buried pipeline, and result also belongs to indirect acquisition, need to manually carefully analyze and school
It tests, meanwhile, such methods are not suitable for detecting the pipeline under the regions such as highway, railway or river, ocean yet, cannot achieve to pipe
The complete detection in road.For these problems existing for pipeline added salts, Inner Examination Technology on Pipeline comes into being.Out of pipeline
Portion is detected, and is the wide pressure pipeline periodic inspection of realization amount multi-panel, the effective means for ensureing normal operation and essential safety
And key problem in technology, it is a kind of highly desirable method for detecting pipeline.
Summary of the invention
The purpose of the present invention is overcoming the shortcomings of in above-mentioned background technique, a kind of pressure pipeline is provided from drifting type ultrasound
Intelligent sphere is detected, which should have the characteristics that easy to operate, detection accuracy is high.
The technical scheme is that
A kind of pressure pipeline detects intelligent sphere from drifting type ultrasound, it is characterised in that: the intelligent sphere includes two balances
Ball and the detection ball being connected to by traction rope between two balanced balls；The detection ball includes spherical inner casing, is arranged in inner casing
In signal processing unit, several ultrasonic probes being evenly arranged on inner casing and the shell for wrapping inner casing；At the signal
Reason unit include built-in PC platform and the channel ultrasonic card for being separately connected built-in PC platform, accelerometer, magnetometer,
Reservoir, high-effect battery；The built-in PC platform also passes through conducting wire and connects ultrasonic probe.
The detection ball and balanced ball are elliposoidal, and the both ends of traction rope are separately connected the longitudinal end of detection ball and balanced ball
Point.
The shell of the detection ball is made of polyurethane foamed material；The inner casing of the detection ball is aluminum alloy materials system
At.
The traction rope is spring；The detection ball and balanced ball are equipped with the pull ring for fixed spring.
The inner casing is docked by two hemispherical Shells.
The beneficial effects of the present invention are:
The present invention is arranged in pipeline and can drift about along pipeline, is realized by the ultrasonic probe being arranged on detection ball
Automatic detection to pressure pipeline, operation is very easy；Specific gravity of the invention and water are almost the same, not only mobile steady, detection
High sensitivity, and blocking phenomenon does not occur for while detecting, the detection of final the defects of realizing to pressure pipeline structure erosion and is commented
Estimate, ensures the safe operation of pressure pipeline.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the invention.
Fig. 2 is overlooking structure diagram of the invention.
Specific embodiment
Below in conjunction with Figure of description, the invention will be further described, but the invention is not limited to following embodiments.
As shown in Figure 1, a kind of pressure pipeline detects intelligent sphere, including detection ball and two balances from drifting type ultrasound
Ball 14.The detection ball and balanced ball are elliposoidal, in order to keep drift posture steady.The detection ball is arranged at two
Between balanced ball, detects and connected between ball and the long axis endpoint of balanced ball by spring 12, and detect and set on ball and balanced ball
There is the pull ring 13 for fixed spring, since spring stiffness is partially soft, the bend pipe position of pipeline 11 can be passed through convenient for intelligent sphere.
The detection ball includes spherical inner casing 1, the signal processing unit being arranged in inner casing, several settings in spherical inner casing
On ultrasonic probe 2 and wrap the elliposoidal shell 4 of inner casing.The ultrasonic probe is evenly arranged on spherical inner casing, and
The signal processing unit of spherical inner housing inner is connected by conducting wire.It is opened on the inner casing and is formed with several through-holes, ultrasonic probe one
One installation is in through-holes and along the radially arrangement of spherical inner casing.
The signal processing unit include built-in PC platform 8, channel ultrasonic card 3, reservoir 9, high-effect battery 7,
Accelerometer 5 and magnetometer 6.The built-in PC platform passes through conducting wire connecting multi-channel ultrasound card, accelerometer and magnetometer,
Channel ultrasonic card reconnects ultrasonic probe.The signal processing unit is used for transmitting-receiving, control, synchronization and the place of ultrasonic signal
Reason.The spherical shape inner casing includes hemispherical Shell made of two aluminum alloy materials, and hemispherical Shell is with rim of the mouth docking mode and by several
Screw fastens, and is equipped with sealing ring at the docking of hemispherical Shell and places the groove of sealing ring.
The accelerometer is three axis accelerometer, for recording acceleration information, smoothly obtains detection ball in the duct
The distance passed through.The ultrasonic probe is used to acquire the corrosion condition data of pipeline, calculates in conjunction with accelerometer data
Distance and location information position the hot spot of pipeline.The magnetometer can detect this from pipeline external application magneto sensor
The Position Approximate of invention.The high-effect battery powers to channel ultrasonic card, accelerometer, built-in PC platform.
The shell is made of polyurethane foamed material, the length of shell (long axis length of elliposoidal, the level in Fig. 1
Direction) it is no more than the 75% of internal diameter of the pipeline, the width of shell (minor axis length of elliposoidal, the vertical direction in Fig. 1) is no more than
The 70% of internal diameter of the pipeline.The inner casing can wrap up various sizes of shell, and such a construction increases the interchangeability of intelligent sphere, avoid
The trouble of different core inner casing, the different size circuit plates of design is fabricated for different size pipe designs.The balanced ball
Depending on size is as needed, the gross density for guaranteeing entire intelligent sphere is identical with the density of water.
It is also provided with tapped through hole on the inner casing of the detection ball, and realizes sealing, spiral shell with M12 thread plug 10 and sealing ring
The position of line through-hole corresponds to the position of reservoir, is not required to open entire spherical inner casing at the end of detection, only need to open thread plug simultaneously
It takes out reservoir and carries out data analysis.
Each component of the invention can be obtained directly in outsourcing.
Finally it should be noted that the above enumerated are only specific embodiments of the present invention.It is clear that the invention is not restricted to
Above embodiments can also have many variations.Those skilled in the art can directly lead from present disclosure
