The invention provides a ship head sonar platform capable of reducing vibration energy transmission, aims to reduce the influence of vibration energy transmission on self noise of the ship head sonar platform, and belongs to the technical field of ship vibration and noise reduction. The sonar platform comprises a hydraulic spring damping device, a transmission rod buffer device, a positioning block fixing device, a hydrophone array and the like, the transmission rod buffer device comprises a platform, a transmission rod, a supporting spring and the like, the transmission rod comprises two rod bodies hinged to each other, and the upper end of the platform is connected with an upper deck through the hydraulic spring damping device. The positioning block fixing device comprises an upper positioning block and a lower positioning block which are connected in a matched mode, the lower positioning block is connected with the lower deck, the hydrophone array comprises a plurality of hydrophones, an elastic rope and two rigid rods, the two ends of the elastic rope are connected with the two rigid rods respectively, and the hydrophones are arranged on the elastic rope at certain intervals. The sonar platform is mainly used for reducing the background noise of the sonar area at the head of the ship and improving the sonar detection level.

    本发明提出了一种降低振动能量传递的船舶首部声纳平台,旨在降低振动能量传递对船舶首部声纳平台自噪声的影响,属于船舶减振降噪技术领域。该声纳平台包括液压弹簧减振装置、传动杆缓冲装置、定位块固定装置和水听器基阵等,传动杆缓冲装置包括平台、传动杆和支撑弹簧等,传动杆包括两个相互铰接的杆体,平台上端通过液压弹簧减振装置与上甲板相连,定位块固定装置包括配合相连的上定位块和下定位块,下定位块与下甲板相连,水听器基阵包括多个水听器、弹性绳和两个刚性杆,弹性绳两端分别与两个刚性杆相连,多个水听器间隔一定距离布置在弹性绳上。该声纳平台主要用于降低船舶首部声纳区背景噪声,提高声纳探测水平。
