As shown in fig. 1 to 5, the present invention further provides an embodiment of a method for mounting a transducer array, which employs the above-mentioned case 100 for mounting a multi-beam system transducer array; the method comprises the following steps: setting a first predetermined mounting line on the bottom outer plate, and setting a second predetermined mounting line on an upper end surface of the transducer array 500; s1, assembling the transducer case 100 in a reverse state: providing a box top plate 200, a box side plate 210, a box bottom plate 220, a transition plate 320, a base plate 310 and a position adjusting assembly 340; determining a first predetermined straight line 201 of the box top plate 200 and a second predetermined straight line 311 of the mounting end face of the substrate 310 according to the mounting position of the transducer array 500 on the ship body, and determining a predetermined end face position 350 of the lower end face of the substrate 310 according to the angles of the upper end face 510 and the lower end face 502 of the transducer array 500 with the horizontal plane and the external size of the transducer array 500; welding the box side plate 210 and the box top plate 200, the box bottom plate 220 and the box side plate 210, and connecting the transition plate 320 and the base plate 310 through the position adjusting assembly 340; when the lower end surface of the substrate 310 is located at the predetermined end surface position, and the transducer array 500 is mounted on the substrate 310, the lower end surface of the transducer array 500 is flush with the lower end surface of the bottom plate; the first predetermined straight line 201 and the second predetermined straight line 311 are positioned on the same vertical plane; s2, normally assembling the transducer box body 100 on the outer bottom plate of the ship body: assembling the transducer box 100 on the outer hull bottom plate, wherein the first predetermined straight line 201 is coincident with a first predetermined mounting straight line of the outer hull bottom plate; s3, adjusting the position of the lower end surface of the substrate 310 so that the lower end surface of the substrate 310 is located at the predetermined end surface position, and fixing the substrate 310 on the transition plate 320 by using the position adjusting assembly 340; s4, mounting the transducer 500, and mounting the transducer 500 on the substrate 310, wherein the second predetermined straight line 311 coincides with the second predetermined mounting straight line.
In the final state after the transducer 500 is mounted on the transducer case 100, the lower end surface of the transducer 500 is parallel to the horizontal plane, according to actual requirements. The transducer upper end face 501 is generally parallel or at an angle to the transducer lower end face 502. Therefore, the position of the lower end surface of the substrate 310, i.e., the predetermined end surface position 350 defined in the present invention, can be determined by the specific positional relationship between the transducer upper end surface 501 and the transducer lower end surface 502 and the external dimensions of the transducer. Specifically, the angle between the predetermined end surface position and the horizontal plane may be determined according to the angles between the transducer array upper end surface 501 and the transducer array lower end surface 502 and the horizontal plane; and determining the distance between the preset end surface position and the lower end surface of the box bottom plate according to the thickness of the transducer array in the vertical direction. In the present embodiment, the transducer upper end surface 501 is parallel to the transducer lower end surface 502, and thus, it is only necessary to ensure that the lower end surface of the substrate 310 is parallel to the horizontal plane.
The inverse manufacturing refers to a process of manufacturing the transducer case 100 in which the transducer case 100 is placed in a direction opposite to the direction in which the transducer case 100 is placed when mounted on the hull. Specifically, the top board 200 of the case is placed on the fabrication table, the lower end surface of the top board 200 of the case faces upward, and the side boards 210 of the case are welded in sequence. Correspondingly, the transducer box 100 is normally assembled on the outer bottom plate of the hull, that is, the box top plate 200 is abutted on the outer bottom plate of the hull, and the manufactured transducer box 100 is welded on the outer bottom plate of the hull.
The transducer array box 100 is manufactured in a single reverse state, so that the transducer array box 100 is convenient and simple, and the precise installation of the transducer array box 100 and a ship body, and the transducer array box 100 and the transducer array 500 can be realized through the matching of the first preset straight line 201 and the first preset installation straight line and the matching of the second preset straight line 311 and the second preset installation straight line; after the box structure is normally installed on the outer plate at the bottom of the ship, the end face of the base plate 310 can be adjusted to a preset end face position through the position adjusting assembly, and finally the transducer array and the multi-beam system are installed, so that the problem that personnel conduct upward construction on the outer plate at the bottom of the ship is solved as much as possible, accuracy control is achieved, construction efficiency is improved, construction period is shortened, and production cost is reduced.
Specifically, in this embodiment, the box top plate 200, the box side plates 210, the box bottom plate 220, the transition plate 320, and the base plate 310 are all flat plates, and the box top plate 200, the transition plate 320, and the base plate 310 are cut according to a design size. The transition plate 320 is cut according to the design size, and the height dimensional tolerance of the transition plate 320 is controlled within +/-2 mm because the lower end surface of the base plate 310 is finally flush with the horizontal plane. Waist-shaped holes for fixing the connecting angle steels 341 and circular screw holes for fixing the multi-beam grounding pieces are respectively processed on the transition plate 320, the base plate 310 and the box body side plate 210, the screw holes all use the connecting end part of the transition plate 320 and the box body top plate 200 as a positioning reference point, and the position deviation is controlled within +/-2 mm.
For convenience of description, in the present embodiment, the top plate 200, the transition plate 320, and the base plate 310 of the case may be idealized as flat plates having no thickness. The box body top plate 200 is a symmetrical figure, the first preset straight line 201 is a symmetrical straight line, and the corresponding first preset installation straight line is a midship line of a bottom outer plate. And the box top plate 200 is arranged along the direction parallel to the horizontal plane, the transition plates 320 are symmetrically welded on both sides of the box top plate 200, and the transition plates 320 are vertically assembled with the box top plate 200.
When assembling, in order to further ensure the assembling accuracy, the tolerance of the transition plate 320 and the pre-installation position is controlled within +/-3 mm, and the perpendicularity tolerance of the transition plate 320 and the box top plate 200 is controlled within 1 degree. During actual welding, the welding sequence follows the symmetrical welding principle of double welders, and the welding is carried out by adopting split gradual backing welding and small welding parameters. In order to secure the strength of the transition plates 320, reinforcing toggle plates may be further provided between the transition plates 320. During actual welding, the welding sequence follows the principle of symmetric welding of even welders, the deformation of the transition plate 320 is monitored, and the ultra-poor precision of the transition plate 320 is prevented.
The case side plate 210 is fitted to the lower end surface of the case top plate 200 along the periphery, and a sacrificial anode 520 is mounted on the inner side of the transducer case 100. A box body bottom plate 220 is assembled below the box body side plate 210, and the lower end surface of the box body bottom plate 220 is parallel to the horizontal plane; wherein, the transducer mounting hole 221 reserved on the bottom plate 220 of the case is approximately aligned with the up-down direction of the position to be mounted of the transducer 500.
After the transducer array box 100 is manufactured, the fore and aft identification can be marked. The transducer case 100 is painted. The screw holes on the transition plate 320 of the transducer case 100 can be plugged with putty, and the sacrificial anode 520 can be wrapped and protected. The transducer array case 100 is sand washed and protected by painting.
The position adjusting assembly 340 includes a plurality of connecting angles 341, a first adjusting bolt 342, and a second adjusting bolt 343; the first adjusting bolt 342 is connected with the transition plate 320 and the first end of the connecting angle 341, and the second adjusting bolt 343 is connected with the base plate 310 and the second end of the connecting angle 341; in step S1, the transition plate 320 is connected to the base plate 310 through the position adjustment assembly 340, the first adjustment bolt 342 is disposed between the transition plate 320 and the connection angle 341, and the second adjustment bolt 343 is disposed between the base plate 310 and the connection angle 341 in an unthreading state, so as to facilitate the adjustment of the position of the lower end face of the base plate 310 in the later period; in step S3, when the lower end surface of the base plate 310 is located at the predetermined end surface position 350, the first adjustment bolt 342 and the second adjustment bolt 343 are tightened, so that the lower end surface of the base plate 310 is accurately adjusted to the predetermined end surface position 350.
Specifically, when the position of the lower end surface of the substrate 310 is adjusted, the lower end surface of the substrate 310 is adjusted to the predetermined end surface position 350 and fixed by the first adjusting bolt 342 and the second adjusting bolt 343. In this embodiment, the adjusting screw 400 may be temporarily welded to the upper end surface of the substrate 310 and the case bottom plate 220, the relative height of the case bottom plate 220 is adjusted by the extension and contraction of the adjusting screw 400, and finally the first adjusting bolt 342 and the second adjusting bolt 343 are locked to position the substrate 310 of the transducer array case 100. The adjustment of the position of the substrate is facilitated by temporarily welding and applying the adjusting screw 400, and the number of operators can be reduced.
Since the lower end surface of the substrate 310 of the present embodiment is adjusted to the predetermined end surface position, the lower end surface of the substrate 310 is parallel to the horizontal plane. Therefore, the flatness tolerance of the substrate 310 can be controlled within 3mm during the adjustment process; when the second adjustment bolt 343 is tightened, if a local over-tolerance is found, the second adjustment bolt 343 can be fastened in place by adding a spacer between the nut of the second adjustment bolt 343 and the angle 341. Finally, the base plate 310 is fixed to the connection angle 341 by the pressing plate 344.
The height difference between the lower end surface of the base plate 310 and the predetermined end surface position 350 is adjusted by extending or shortening the adjusting screw 400 and fixed by the first adjusting bolt 342, wherein the height difference of the lower end surface of the base plate 310 can be controlled within ± 1 mm.
After the position of the substrate 310 is adjusted, the ground wire 530 may be fixed to the connection angle 341, and the small fillet weld between the connection angle 341 and the transition plate 320 is performed by a full-length welding process, where the fillet weld is 5 mm. The welding adopts small current, gradually retreats in different steps, and the flatness of the substrate 310 is monitored in the welding process. The first adjusting bolt 342 is removed, the transducer 500 is fixed on the substrate 310, and meanwhile, the transducer cable 510 is laid in a designated cabin, and a cable bundle needs to be bound and fixed in the transducer box body 100 to prevent shaking and abrasion.
And a sealing plate is arranged at the residual gap between the lower end surface 502 of the transducer array and the lower end surface of the box bottom plate 220, so that the working state of the transducer array 500 is more stable. And the shape of the sealing plate is cut on site according to the actual residual space. The bolt grooves (including the sealing plate bolts and the transducer bolts 540) exposed outside the hull and the gaps between the transducer and the opening of the box bottom plate 220 are smoothed with putty. Finally, the exposed surface of the transducer array 500, i.e., the lower end surface 502, is coated to protect against marine growth.
Finally, the system attachment of the transducer array 500 is installed. And system terminal accessories such as a receiver, a control station and the like in the cabin are installed, and after the system is completely installed and before a ship is launched, the relative positions of the acoustic center of the transducer, the compass motion sensor and the GPS coordinates are measured for correcting the system deviation.
