In the diameter of fluting 7, effect is the design equal by aperture, diameter, and it is logical to reduce first through hole 3, sound wave
The channel of 7 composition of road 6 and fluting is transmitted noise quickly, is isolated in 2 inner wall of outline border to the resistance of noise transmission
The side opposite with the second through-hole 5 is uniformly provided with groove 8, and is all pasted with sound absorption cotton 9 by super glue on groove 8.
Groove 8 and all semicirculars in shape of cotton 9 that absorb sound, the size of spacing is less than into 4 spacing of sound area between two end grooves 8
Size, effect be by semicircular design, can be by so that into noise channel of acoustic wave 6 inside and contacted with groove 8
Groove 8 and sound absorption 9 good absorption of cotton, will not make noise directly detour after blocking and transfer away, can be abundant with sound absorption cotton 9
Contact, and by the design of spacing size, further such that noise and sound absorption cotton 9 come into full contact with, sound absorption cotton 9 is porous sound absorption
Material, mainly includes numb cotton wool felt, organic fibrous material, inorganic fibers, mineral wool, mineral wool, urea-formaldehyde foam material etc.,
The micropore largely to interpenetrate and gap are uniform-distribution with inside it, micropore is outwardly open so that sound wave enters inside micropore.
The device by setting isolation outline border 2, first through hole 3, into sound area 4, the second through-hole 5, channel of acoustic wave 6, fluting 7,
Groove 8 and sound absorption cotton 9, carry out absorbing weakening and change its direction, noise is avoided to enter sonar contact to the noise that side comes
The receiving area of device noumenon 1 weakens the interference of noise to a certain extent, avoids bringing deviation to testing result, improves
The accuracy that sonar contact device noumenon 1 detects.
The side of 1 inner wall of sonar contact device noumenon is provided with level-one damping chamber 10, and the inside of level-one damping chamber 10 is equal
Even to be welded with damping spring 11, the inside of level-one damping chamber 10 is welded with second level damping chamber 12, and second level damping chamber 12 is close to one
First rubber mount 13 is pasted with by glue on the side inner wall of grade damping chamber 10, the inside of the first rubber mount 13 is uniformly solid
Surely there is the first damping rubber block 14, be pasted with by glue on side inner wall of the second level damping chamber 12 far from level-one damping chamber 10
Two rubber mounts 15, and the second damping rubber block 16 is uniformly fixed on the second rubber mount 15, level-one damping chamber 10 and damping
By being welded to connect between spring 11, the first damping rubber block 14 and the first rubber mount 13, the second damping rubber block 16 and the
It is all pasted and is connected by super glue between two rubber mounts 15, effect is the side for pasting connection by welding, super glue
Formula, so that level-one damping chamber 10 and damping spring 11, the first damping rubber block 14 and the first rubber mount 13, the second rubber shock-absorbing
Stable connection between block 16 and the second rubber mount 15, the first damping rubber block 14 and the second damping rubber block 16 are all in semicircle
Shape, and it is staggeredly symmetrical, effect is by semicircle and staggeredly symmetrical design, so that the first damping rubber block
14 and second damping rubber block 16 contact when can be very good to disperse plus-pressure, to weaken to extruding force.
The device passes through setting level-one damping chamber 10, damping spring 11, second level damping chamber 12, the first rubber mount 13, the
One damping rubber block 14, the second rubber mount 15 and the second damping rubber block 16, by sonar contact device noumenon 1 itself
On the basis of be arranged two-stage shock-damping structure, the extruding force being subject to it weakens to a certain extent, to improve sonar contact device sheet
The intensity of body 1 plays a protective role to sonar contact device noumenon 1, avoids being damaged because hydraulic pressure is excessive, will not influence dress
The normal work set improves the practicability of device.
Working principle: in use, first as shown in Fig. 1, when there is noise to come on the left of sonar contact device noumenon 1
When, a part of noise that will cause interference will enter in the horn chamber of isolation outline border 2, this partial noise will be divided at this time
Two paths, one is stopped into the entity other than sound area 4, is detoured and is walked, have changed its direction at this time, will not visit to sonar
It surveys device noumenon 1 to interfere, another can be by entering the sound wave in isolation 2 inner wall of outline border into the second through-hole 5 on sound area 4
In channel 6, it is applied directly on groove 8 and sound absorption cotton 9 at this time, a part will be absorbed by the sound absorption cotton 9 on groove 8, to making an uproar
Sound is weakened, and another part will detour, and is moved along the channel that channel of acoustic wave 6, fluting 7 and first through hole 3 form, by one
The horizontal direction of beginning becomes direction transmitting normal thereto, so as to avoid sonar contact device noumenon 1 by noise herein
Interference；
When sonar contact device noumenon 1 reaches detection target and is in deeply not shallow region, the hydraulic pressure effect of surrounding
The impact force of power or experience will act in sonar contact device noumenon 1, the damping spring inside level-one damping chamber 10
Under 11 effects, primary weakening is carried out to such power and has been buffered, will then be applied on second level damping chamber 12, pass through the first rubber
Cushion 13 squeezes the second damping rubber block 16, so that this active force is weakened by dispersion, to achieve the purpose that damping, buffering, to sound
Detection device ontology 1 plays certain protection, and operation leaves it at that.
