The invention discloses a detector for a metal target submerged underwater, dragging equipment is connected with a detection device through a dragging device, and the dragging equipment is provided with an optical observer, a sound detector, a response sound beacon, a height gauge and signal processing and result display equipment. An electric loop is formed by the first electrode, the second electrode and the water medium, fixed electric field space distribution is generated between the first electrode and the second electrode in water, and when a water bottom sinking metal target exists in the space nearby the first electrode and the second electrode or the metal target exists nearby, the resistance of the water medium space is changed, therefore, the stably distributed space electric field is changed, whether the underwater metal target exists or not can be determined after the detection signals are compared, analyzed and processed, and the position of the underwater metal target and the detection result are displayed through the signal processing and result display device. The device has the advantages of simple structure, safety, reliability, light weight and good detection effect.
本发明公开了一种用于水底沉埋金属目标的探测器,在拖动设备上通过拖曳装置与检测装置联接,拖动设备上设置有光学观察器、声探测器、应答声信标、高度仪、信号处理与结果显示设备。本发明通过第一电极、第二电极与水介质构成电回路,在水中第一电极与第二电极之间产生固定的电场空间分布,当第一电极与第二电极附近空间存在水底沉埋金属目标时或附近存在金属目标时,使水介质空间的电阻发生变化,从而使稳定分布的空间电场产生变化,对检测信号进行对比分析处理后,能够确定水底是否存在水底沉埋金属目标,并通过信号处理与结果显示设备显示目水底沉埋金属目标的位置和探测结果,本发明具有结构简单、安全可靠、重量轻、探测效果好的优点。
