An underwater point detection device based on sonar comprises a suspension body and a detection head arranged on the lower side of the suspension body, balance faces are arranged on the two side faces of the suspension body, the distance between the balance faces on the two sides is gradually reduced from top to bottom, two shunting faces are symmetrically arranged on the front surface of the suspension body, and side openings are formed in the positions, close to the upper ends of the balance faces, of the two side faces of the suspension body. A flow wing is fixedly connected to the inner side of the side opening, two symmetrical flow guide faces which are gradually folded together extend out of the rear face of the suspension body, and a tail plate is rotationally connected to the rear end of the suspension body. A suspension point of the traction mechanism is located on the upper surface of the suspension body. When the point detecting equipment is pulled towards the front upper portion, water flow passes through the flow wing and then presses the suspension body, the tail plate swings under the action of the water flow on the two sides, the water flow speed of the lower surface of the flow wing is high, therefore, the pressure intensity is low relative to the upper portion, the tail plate can be subjected to pressing force, the balance state in the suspension process is kept good, stable starting during moving is facilitated, and the service life of the device is prolonged. And the problem of poor detection precision caused by floating along with traction and pulling does not occur.

    一种基于声呐的水下探点设备,包括悬体、设置在悬体下边的探测头,悬体的两侧面开设有平衡面,两侧平衡面间距自上至下逐步减小,悬体的前表面对称开设两个分流面,悬体的两侧面靠近平衡面上端处开设有侧口,侧口的内侧固定连接有流翼,悬体的后面延伸出两个对称的并逐步收拢在一起的导流面,悬体的后端转动连接有尾板;牵引机构的悬吊点位于悬体的上表面。本发明探点设备在受到朝向前上方牵引时水流经过流翼后将悬体下压,尾板受两侧水流作用而发生摆动,流翼下表面水流速度较大,因此压强相对于上方来说较低,会受到一个下压的力,因此悬吊中平衡态保持较好,利于移动时平稳起步,不会发生随着牵引拉扯而上浮,从而导致探测精度变差的问题。
