The invention relates to the technical field of ship underwater detection equipment and relates to a novel acoustic transmission window for a shipborne high-frequency sonar. The novel acoustic transmission window comprises an acoustic window shell plate; the acoustic transmission window shell plate is embedded in a water tank shell plate and is in sealing fit with the water tank shell plate; the high-frequency sonar is fixed in a water tank; the acoustic transmission window shell plate is divided into a plurality of non-acoustic-transmission vibration suppression and noise reduction areas anda plurality of acoustic transmission areas; and the acoustic transmission areas and a sonar array plane in the high-frequency sonar are arranged oppositely at intervals. The high-frequency sonar is fixed in a water tank; the water tank body can be sealed through a watertight tank cover; water can be pumped and drained through a drainage pump; the water tank can protect the high-frequency sonar; when the high-frequency sonar needs to be maintained and overhauled, the water in the water tank is drained, people can enter the water tank to maintain the high-frequency sonar; the sonar array plane in the high-frequency sonar faces the acoustic transmission areas of the sound transmission window shell plate conveniently, so that the acoustic transmission window with low acoustic transmission lossand high strength is provided for sonar use, and the application requirement of high-performance detection is met.

    本发明涉及舰船水下探测设备技术领域,尤其是一种用于船载高频声呐的新型透声窗,包括透声窗壳板,透声窗壳板镶嵌在水舱壳板中且二者密封配合,高频声呐固定在水舱内部,透声窗壳板划分为若干非透声抑振降噪区和若干透声区,透声区和高频声呐中的声呐阵面相对间距布置,本发明的高频声呐固定在水舱内部,水舱本身可以通过水密舱盖密封,也可通过排水泵抽排水,水舱既能保护高频声呐,当需要维护和检修高频声呐时,将水舱内部的水排出,人便能进入水舱内部维修高频声呐,较为方便高频声呐中的声呐阵面面向透声窗壳板的透声区,为声呐使用时提供低透声损失和高强度的透声窗,满足高性能探测的应用需求。
