Underwater detection device convenient for accurate positioning and fixing

Abstract

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.

Description

technical field [0001] The invention relates to the related field of detectors, in particular to an underwater detection device that is convenient for precise positioning and fixing. Background technique [0002] Detector is a kind of information collection device. The common ones are metal detectors, trajectory detectors, aerospace detectors, etc. It is widely used and can complete various tasks in harsh environments where humans cannot work normally. [0003] The underwater detector is a kind of intelligent underwater equipment used to detect the underwater environment and perceive the target signal. When the underwater detector dives naturally, it is affected by the direction of the water flow and the undercurrent inside the water body. Affected by many factors, it is not easy to complete the position accuracy control of natural diving, and it is not conducive to the stability of the long-term work of the detector, and there is a certain danger in artificial placement.
