The invention discloses an underwater detection device convenient for accurate positioning and fixing. The device comprises a working box body, a power cavity is formed in the working box body, a motor is fixedly arranged on the inner wall of the left side of the power cavity, the underwater detection device is driven to dive through thrust generated by rotation of a propeller, the thrust direction borne by the underwater detection device is changed by changing the direction of the propeller, and the device floats upward. When the device dives, air in a floating and sinking cavity is exhausted, water is injected into the floating and sinking cavity, the overall weight of the device is increased, the buoyancy of the device is reduced, the stability of the device in the diving process is facilitated, and the influence of water flow on the diving position of the device is reduced; when the device dives to the water bottom, a drill bit is used for drilling and feeding the water bottom to achieve fixing of the device, the device can stably conduct underwater detection work for a long time, the underwater air communication with the water surface is achieved through a released buoyancy plate when the device floats upwards, and air is injected into the floating and sinking cavity to reduce the weight of the device and increase buoyancy; and the rapid upward floating of the device is achieved.

    本发明公开的一种便于精准定位固定的水下探测装置,包括工作箱体,所述工作箱体内设有动力腔,所述动力腔左侧内壁上固定设有电机,本发明利用螺旋桨转动产生的推力带动装置下潜,并通过改变螺旋桨方向以改变装置所受推力方向,实现装置的上浮,本装置在下潜时排出浮沉腔中的空气并对其注入水,增加装置的整体重量并减小其浮力,有利于装置在下潜过程中的稳定性,减小了水流对装置下潜位置的影响,在装置下潜到水底时利用钻头对水底钻孔进给实现装置的固定,有利于装置长时间稳定的进行水下探测工作,本装置在上浮时通过放出的浮力板实现水下与水面的空气连通,通过对浮沉腔中注入空气以减小装置重量并增加浮力,实现装置的快速上浮。
