An aviation sonar buoy for deep sea search and rescue comprises a parachute landing mechanism, a water surface electronic bin and an underwater electronic bin, a depth setting device is arranged on the bottom side of the water surface electronic bin and comprises a cable cylinder, an upper flange and a lower flange, and depth setting cables are spirally wound and stacked in the cable cylinder layer by layer; two ends of the depth-keeping cable are respectively connected with the depth-keeping device and the underwater electronic cabin; the upper flange is provided with a wire burning circuit board, the wire burning circuit board is provided with a plurality of resistors, the plurality of resistors are respectively connected with nylon wires with different lengths, the plurality of nylon wires are respectively connected with different positions of the depth-keeping cable, and the nylon wires can limit the parts, connected with the nylon wires, on the depth-keeping cable from being separated from the spiral winding and stacking positions. When the resistor is powered on, the nylon wire can be burnt out, the unburnt and longest nylon wire can limit the releasing length of the depth-keeping cable from the cable cylinder, the underwater electronic bin can sink gradually according to a plurality of preset gear depths, and the deep sea search range of the aviation sonar buoy is remarkably expanded.

    一种用于深海搜救的航空声纳浮标,包括伞降机构、水面电子仓和水下电子仓,水面电子仓的底侧设有定深装置,定深装置包括电缆筒体、上法兰和下法兰,电缆筒体内以螺旋形逐层缠绕堆叠有定深电缆,定深电缆的两端分别与定深装置和水下电子仓连接;上法兰设有烧丝电路板,烧丝电路板上设有多个电阻,多个电阻上分别连接有不同长度的尼龙线,多个尼龙线分别与定深电缆的不同位置连接,尼龙线能够限制定深电缆上与其连接的部位从螺旋形的缠绕堆叠位置脱离,电阻通电时能够烧断尼龙线,通过未被烧断且长度最长的尼龙线能够限制定深电缆从电缆筒体内的放出长度,水下电子仓就可以按照预定的多个档位深度逐次下沉,显著扩大了航空声纳浮标的深海搜索范围。
