Description
Technical field
The invention belongs to ship domain, it is related to acoustic transducer platform, especially a kind of Half-immersion type marine acoustic platform.
Background technology
Acoustic platform is a kind of hull bottom mounting means of acoustic equipment, is to install acoustic transducer equipment specific concentratedly
The engineering of bay section.By multiple acoustic transducers（Battle array）The installment work of water tank includes the design of this section of hull as an entirety
In construction, what is produced when not only contributing to avoid each independently installed mutually ties up position and matching component, cross pipe-line weight
The generation of the phenomenon such as folded, saves installing space, moreover it is possible to reduce acoustic interference between acoustic transducer, reach each equipment task performance
Optimize, while resource and material can be efficiently utilized again, to ensure that the ship measuring apparatus reaches that expected tactics, technology refer to
Mark provides reliable guarantee.
At present, acoustic platform is by multiple acoustic transducers（Battle array）Water tank is constituted.An acoustics is specially designed in cabin space
Platform freight space, acoustic transducer（Battle array）Water tank is arranged in acoustic platform cabin, and acoustic transducer water tank bottom is connected with hull,
With contact with sea water.Have the drawback that：1st, tank box is directly welded on hull bottom bottom plate, is difficult to control to, is held during release stress
The deformation of water tank bottom plane and the deformation of bottom flange sealing trough are easily caused, so as to cause bottom entrant sound plate sealing property by shadow
Ring；2nd, it is bolted on after the punching of entrant sound edges of boards edge on the flange of water tank bottom, it is bolt strained to be difficult to ensure uniform, and entrant sound
The bolt hole of plate and inner flange it cannot be guaranteed that be aligned, on the side during stress completely, it is easy to causes to ftracture at entrant sound plate punching；3、
Echo noise in water tank is larger；4th, entrant sound plate face is to the easy apposition growth marine growth in seawater side.
By retrieval, following two correlations patent document altogether is found：
1st, one kind monitoring device used in during multibeam calibration（CN201034719）, passed through by drill bit
Drilling rod body that threaded connector and drilling rod are integrally fixed, connecting bracket, support bar, electronics storehouse, electronics bin bracket, kentledge,
Kentledge support and hoisting ring composition.Electronics bin bracket is fixed on 3 support bars by 3 semicircle anchor ears, and electronics storehouse is put
Put on electronics bin bracket center position, multifrequency transmitting transducer group is arranged on side below connecting bracket, multiple-frequency signal receives
Device group can adjust whole in the side towards multifrequency transmitting transducer group, this equipment by changing the ballast number of blocks placed
Gross weight needed for marine exploration drilling rod.
2nd, the platform of bottom sediment sample acoustical testing is carried out under the conditions of a kind of constant temperature and pressure（CN201886000U）, bag
Include sample bin, specimen holder, constant-voltage equipment, thermostat, pressue device, pressurization storehouse, pressure plunger, temperature transducer, pressure measurement biography
Sensor, displacement transducer and transducer erecting device, wherein specimen holder are arranged on the inside of sample bin lid；Pressurization storehouse and sample bin are close
Envelope is fixedly connected；Pressurize storehouse inside pressure plunger and sample bin piston connect, and by dynamic sealing through pressurization Cang Gai with
Displacement transducer is connected；2 groups of transducer erecting devices are separately mounted to inside sample bin outer side of lid and pressure plunger.
Contrasted by technical characteristic, above-mentioned two patent documents have relatively big difference with the present patent application.

Upper flanges are connected with casing is respectively mounted blast pipe and water inlet pipe, and sound absorbent rubber plate is fixedly mounted with the inwall of casing, and it is special
Levy and be：
Installation pedestal is fixed with the lateral wall cladding of casing, the installation pedestal is by bolt and uses sealing ring and casing
Upper flanges be coaxially fixedly mounted with, the installation pedestal is packed on hull bottom plate；
The lower bottom side outer rim of the entrant sound plate is formed with step, and pressure ring is provided with the entrant sound plate of the stepped portions, should
Pressure ring is engaged with the lower flange screw thread in casing using sealing by hold-down bolt and is solidly installed, and entrant sound plate is close to laxative remedy
It is blue.
Moreover, sticking sound absorbent rubber plate again after the first blasting treatment of the madial wall of the casing.
Moreover, first applying anti-marine growth paint before lower water to the lower bottom side of seawater in entrant sound plate face.
Moreover, the casing is circular or square.
The advantages of the present invention are：
1st, this acoustic platform welds water tank alow by water tank pedestal, after release stress, then installs water tank, passes through spiral shell
