Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
The utility model relates to a kind of easy device of acoustic sounding instrument calibration standard target, as shown in Figure 1, comprise research ship 1 that transducer 3 is housed, hand-held fishing rod 5, two fixedly fishing rod 6 and three nylon monofilaments 7, described two fixedly an end of fishing rod 6 be fixed on ship side one side of research ship 1, fixedly fishing rod 6 and hand-held fishing rod 5 is fixing with two respectively for one end of described three nylon monofilaments 7, the other end common with standard ball 8 links, described standard ball 8 belows also are connected with balancing weight 9.Wherein, described transducer 3 is positioned at hull bottom or the topside of research ship 1.Described balancing weight 9 is arranged on 1 meter, standard ball 8 belows.The quality of described balancing weight 9 is 4-6kg.Described hand-held fishing rod 5 and fixedly fishing rod 6 be the carbon element bar.Described hand-held fishing rod 5 and fixedly the bar length of fishing rod 6 be 8 meters, the long 80-100 rice of fishing line.The length of described nylon monofilament 7 is 100 meters, and diameter is 0.5mm.The diameter of described standard ball 8 is 21.2～38.1mm.
This device is read two parts and is formed by the setting of standard ball depth of water scope, beam signal.
Standard ball depth of water scope is set: in the actual trimming process, (diameter 21.2～38.1mm) own vols are less to consider standard ball, being subject to ocean current impacts and drift everywhere, therefore be that the lead of 4-6kg ties up to 1m place, standard ball below with a quality, utilizing diameter is the nylon monofilament link standard ball of 0.5-1mm.Simultaneously, for guaranteeing to eliminate near-field effect and ocean current impact, vertical range is R between established standards ball and transducer
Opt+ 2m.(R
OptTheoretical vertical range for standard ball and transducer).
Beam signal reads: be that 0.5mm, length are that 100m nylon monofilament links with three same specification fishing rods respectively that (the fishing rod material is the carbon element bar with three diameters; Pole is long: 8m, fishing line is long: 100m, subsidiary fishing lines reel), the other end all links with standard ball, simultaneously 1m place is the lead link of 4-6kg with a quality below standard ball, is the interference to the standard ball trimming process of the target strength of elimination lead, and established standards ball signal depth of water scope is (R
Opt+ 2) ± and 0.5m, by changing standard ball at distance transducer (R
Opt+ 2) ± and the interior position of 0.5m scope, the beam signal of standard ball is evenly appeared in the four-quadrant at software correction interface, preservation is upgraded, thereby finishes the work of acoustic sounding instrument calibration standard target.
The below further specifies the utility model with a specific embodiment.
As shown in Figure 1, research ship 1 is docked in the investigation waters 2, takes hull bottom installation or topside fixed form (fixing with stainless-steel tube 4) to be installed on the research ship 1 transducer 3.Be that 0.5mm, length are that 100m nylon monofilament 7 links with three same size fishing rods respectively that (the fishing rod material is the carbon element bar with three diameters; Pole is long: 8m, fishing line is long: 80-100m, subsidiary fishing lines reel), the other end of nylon monofilament 7 all links with standard ball 8, and simultaneously, 1m place and a quality are lead 9 links of 4-6kg below standard ball 8; Measure temperature, the salinity in investigation waters, for the transducer 3 of different frequency, select size and the corresponding target strength (TS value) of unlike material standard ball, above-mentioned parameter is inputted in the acoustic treatment software.Standard ball 8 was inserted in the liquid detergent solution that concentration is 20-40% 5 minutes the echoed signal that produces in order to the foaming of eliminating the standard ball surface.
The fixedly fishing rod 6 that above-mentioned link is good is fixed on ship side one side, and the isometric distance (2m) that stretches out, and the distance of establishing 3 of ship side and transducers is rm; Inserting the standard ball 8 that is connected with lead 9 apart from the water surface degree of depth is R
OptIn the investigation waters 2 of+r+2m, two fixedly 7 angles of nylon monofilament of linking of fishing rod 6 be 55 °-65 °; To hand fishing rod 5 and place other side ship side, move the dimensional orientation of regulating the mode adjustment criteria ball of nylon monofilament length with fishing lines reel along ship side by hand-held fishing rod 5, the beam signal of standard ball 8 is uniformly distributed in the four-quadrant at software correction interface, preserve, upgrade, finish the work of acoustic sounding instrument calibration standard target.
Be not difficult to find, the utility model is undesirable in sea conditions, and investigation ship model is not fixed, when the transducer mounting means changes, can be finished easy, quickly the correction work of detection instrument standard target.
