Description
Technical Field
The invention relates to a self-contained ADCP (acoustic Doppler current profiler) suitable for deepwater distribution, belonging to the field of applied acoustics.
Background
An Acoustic Doppler Current Profiler (ADCP) is an advanced real-time measuring device for Current flow rate and flow rate in the world. By using the acoustic Doppler principle, the ADCP emits acoustic pulses to the water body, the acoustic pulses generate reflected waves after encountering particles which are suspended in the water body and move along with the water body, the ADCP receives the reflected waves and records the frequency change between the reflected waves and the emitted waves, and the frequency change is Doppler frequency shift, so that the water flow velocity is calculated. The working modes of the ADCP mainly include: ship-borne sailing type, ship-borne towing type, underwater self-contained type and shore-based direct reading type. The underwater self-contained type is generally provided with ADCP in the modes of submerged buoy, buoy and the like, the storage battery supplies power, and the equipment collects the flow velocity and flow field of the water body and other data for a long time at a relatively fixed place. Common self-contained ADCPs which need to be laid in deep water need to be processed by high-strength materials or filled with oil in the inner cavity of equipment to bear external high water pressure. The commonly used materials with seawater corrosion resistance and high strength are generally made of titanium alloy, and the equipment processing and production cost is high. If the processing equipment shell is made of 316L stainless steel materials with low strength and seawater corrosion resistance, when the equipment shell is used in deep sea, the inner cavity is filled with low-compression hydraulic oil, even a compensation oil bag communicated with the inner cavity is arranged outside the equipment to keep balance of internal pressure and external pressure, and the equipment needs to be drained completely in the process of maintaining a circuit board and debugging, so that the work is complicated. After the oil is filled in the inner cavity, the external high pressure of the ADCP can be directly transmitted to precise devices such as capacitors and inductors on the circuit board through hydraulic oil, and the design and production cost of the circuit board and the like is increased.
