Abstract
An underwater detector includes a sealed enclosure, inside an infrared sensor module is disposed. The module rotates around a spindle at a fixed angular velocity along a horizontal plane. An electronic compass disposed on the module. A bottom of the sealed enclosure connected to an indicator through a rotary shaft, and the indicator rotates around the rotary shaft on the horizontal plane. The indicator includes a head and tail fin. A light source emits a light beam vertically upwards on the tail fin. The module is configured to trigger, when receiving the light beam, the electronic compass records a real-time direction relative to the spindle, which is processed by a processor module to obtain a direction of the water flow. A spring connects between the head and tail fin. The infrared sensor module transmits a moment of receiving the light beam to the processor module to calculate the water flow.
