Description
Technical field
This utility model relates to sound wave lossless detection field, is specifically related to a kind of remote control sound wave generating device.
Background technology
Compared with ultrasonic listening, although acoustic detection precision is low, but it is big to have investigation depth, the feature that detection range is remote.Therefore, in pile's integrity testing, ground geology physical prospecting, sound wave lossless detection is widely used.Present stage, the sonic source device that sound wave (20Hz-20kHz) detector that market is sold provides is hand hammer.Hand hammer needs arm directly to operate, and some detects space, and testing staff can not enter, in shield machine excavation face, earth-boring, it is impossible to fire sound source by hand hammer.At sound wave lossless detection, for improving signal to noise ratio, the method that Signal averaging is usually taken, but during hand hammer percussion, owing to each hammering angle, dynamics, position are the most different, the effect of Signal averaging is the most undesirable.
Summary of the invention
The purpose of this utility model is: provide remote control sound wave generating device a kind of applied widely, that Signal averaging is effective.
This utility model is achieved through the following technical solutions: a kind of remote control sound wave generating device, including steel pipe, described steel pipe includes inflating section and exhaust section, it is provided with electromagnetic valve between described inflation section and exhaust section, described inflation section end seal is also communicated to inflator pump by gas tube, the end of described exhaust section is provided with impingement baffles, and described exhaust section is provided with some steam vents near one end of impingement baffles；Steady pin and metal ball it is provided with in described exhaust section, described steady pin is located at the one end near electromagnetic valve, and described metal ball is connected to steady pin by spring, and the external diameter of described metal ball is equal to the internal diameter of exhaust section, when described metal ball contact impact baffle plate, described spring is in extended configuration.
Further, the two ends of described steady pin are welded on exhaust section inwall, described steady pin axially and exhaust section axially vertical and its be centrally located on the axis of exhaust section.
Further, described spring is connected to the center of steady pin.
Further, described metal ball is stainless steel ball.
Further, described some steam vents are uniformly distributed ringwise.
Further, described impingement baffles is bolted on exhaust section.
Compared with prior art, this utility model has the advantages that
One, this device implements long-distance remote control, it is not necessary to testing staff directly arrives test site, can be used for space or the inaccessiable space of testing staff of some danger.
Two, this device realizes multiple impact by inflation, electromagnetic valve, spring, steel ball can be controlled by air pressure adjustment and clash into dynamics, stainless steel ball is for linear motion in steel pipe, angle, the position that can make to clash into identical every time, is overlapped obtaining the test signal that signal to noise ratio is higher to test signal.
Three, impingement baffles uses bolt to be connected with steel pipe, by changing impingement baffles, can change the frequency of sound source, the most also can be without impingement baffles, and such as the detection of stake, stainless steel ball directly clashes into an end face.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1, a kind of remote control sound wave generating device, including steel pipe 1, described steel pipe 1 includes inflating section 11 and exhaust section 12, it is provided with electromagnetic valve 2 between described inflation section 11 and exhaust section 12, described inflation section 11 end seal is also communicated to inflator pump by gas tube 3, and the end of described exhaust section 12 is provided with impingement baffles 4, and described exhaust section 12 is provided with some steam vents 5 near one end of impingement baffles 4；Steady pin 6 and metal ball 7 it is provided with in described exhaust section 12, described steady pin 6 is located at the one end near electromagnetic valve 2, described metal ball 7 is connected to steady pin 6 by spring 8, the external diameter of described metal ball 7 is equal to the internal diameter of exhaust section 12, when described metal ball 7 contact impact baffle plate 4, described spring 8 is in extended configuration.The two ends of described steady pin 6 are welded on exhaust section 12 inwall, described steady pin 6 axially and exhaust section 12 axially vertical and its be centrally located on the axis of exhaust section 12.Described spring 8 is connected to the center of steady pin 6.Described metal ball 7 is stainless steel ball.Described some steam vents 5 are uniformly distributed ringwise.Described impingement baffles (4) is bolted on exhaust section (12).
Being fixed on an end face or cutter head of shield machine by this device or tying up stretches in earth-boring on steel pipe, air pump is first used by gas tube 3, inflation section 11 to be inflated, when air pressure is raised to certain value (such as 300kPa), stop pump gas, electromagnetic valve 2 wire connected power, electromagnetic valve 2 is opened, powerful gas is gone out from valve, rush in exhaust section 12, under gas pressure, stainless steel ball 7 forward impact, strike on impingement baffles 4, send the biggest sound, the vibrational waveform that sound source causes is measured with sonic test instrument, impingement baffles 4 can also take off from device, stainless steel ball 7 is allowed directly to clash into stake end face, gas is discharged by air vent 5, after air pressure declines, stainless steel ball 7 returns under the pulling force effect of spring 8 at steady pin 6.Disconnect the power supply of electromagnetic valve 2, it is possible to start remote control next time and clash into, carry out and test next time.
