Preferably, a diameter of 3-6 meters of the fine motion array.
Preferably, it is in the annular array module of fan that the fine motion array, which includes at least two, and the array module is in a ring
Splice in array.
The utility model has the beneficial effects that:It connect by using the fine motion array, recorder and with by the recorder
The detection device of computer composition is the detection boulder device being arranged according to fine motion method, simplifies boulder detection process, reduces
Operation difficulty improves detection accuracy.Meanwhile being arranged to be made of the array unit of several various outer diameters by the fine motion array, it can
To need data acquisition device being mounted on the array unit of various outer diameter according to different, application range is increased.This practicality
Novel operating is simple, and using effect is good, use easy to spread.
Description of the drawings
Fig. 1 is the structural schematic diagram of the boulder detection device of the utility model.
Wherein:The 1- fine motion arrays, 2- recorders, 3- computers, 4- data acquisition devices, 5- mounting holes, the installation of the centers 6-
Hole.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Please refer to attached drawing 1, a kind of boulder detection device of the present embodiment, including the fine motion array 1, recorder 2 and with by institute
The computer 3 of recorder connection is stated, the fine motion array 1 is by several various outer diameters and sequentially connected array list in a ring
Member composition, sets the mounting hole 5 there are five installation data harvester 4 on each array unit, five mounting holes 5
The line at center is equipped with center in the regular pentagon centered on the center of the fine motion array 1, the center of the fine motion array 1
Mounting hole 6, six data acquisition devices 4 are separately mounted to five mounting holes 5 of one of them array unit
In the center mounting hole 6, and six data acquisition devices 4 are electrically connected the data logger 2 simultaneously.
Boulder detection device based on above-mentioned technical characteristic, by using the fine motion array 1, recorder 2 and with by the note
It is the detection boulder device being arranged according to fine motion method to record the detection device that the computer 3 that instrument 2 connects forms, and simplifies boulder detection
Process reduces operation difficulty, improves detection accuracy.Meanwhile the fine motion array 1 being arranged to by the array of several various outer diameters
Unit forms, and can need data acquisition device 4 being mounted on the array unit of various outer diameter according to different, increase application
Range.The utility model is easy to operate, and using effect is good, use easy to spread.
In the present embodiment, from top to the bottom end of the fine motion array 1, the outer diameter of each array unit is sequentially increased,
Each array unit stepped connection on the central axis direction along the fine motion array.Such set-up mode conveniently exists
When difference needs, can easily the data acquisition device 4 be mounted on the array unit of various outer diameter, and not
Interference is will produce, has been operated not only simply, conveniently, but also can ensure detection accuracy.
