Marine flow test automatic control device

Abstract

The invention discloses a marine flow test automatic control device and relates to the technical field of automatic control. The marine flow test automatic control device comprises a tested ship, a power part and a control part. The marine flow test automatic control device is characterized in that the power part is integrated by a motor, a speed reducer and a brake, the speed reducer drives a middle transmission wheel and a tensioning wheel through a belt, the middle transmission wheel drives a rotary drum, one end of a lifting loop cable is fixed on the rotary drum, a fish lead is fixed at the other end of the lifting loop cable, a base seat is arranged on the tested ship, a base plate is fixed on the base seat, a winch frame is installed on the base plate, the power device and the control device are installed on the base plate, and the rotary drum is installed on the winch frame. The marine flow test automatic control device has the advantages that lifting of the fish lead is automatic, labor intensity of staff is greatly relieved, flow testing accuracy is further improved, and digitization and computerization of testing data are achieved.

Description

Technical field [0001] The invention relates to the technical field of automatic control, in particular to an automatic control device for marine flow testing. Background technique [0002] At present, all hydrological stations generally use suspension lead fish lanyard flow meter to conduct flow measurement during flat, low water and freezing flood periods. The lead fish lifting and lowering adopts manual manual operation, and the labor intensity of the test personnel is large; the water depth of the vertical line and the water depth of the measuring point are obtained by manually reading the inscription on the suspension cable. The friction between the marking mark and the pulley causes the inscription Unclear lines can easily cause errors in readings. The use of electric bells and stopwatches for flow rate measurement not only takes time and effort, increases the duration of the test, but also easily causes errors in signal numbers and stopwatch readings. Summary of the inven...

AI Technical Summary

Problems solved by technology

The lifting and lowering of the lead fish is manually operated, and the labor intensity of the testers is high; the water depth of the vertical line and the water depth of the measuring point are obtained by manually reading the markings on the suspension cable. Due to the friction between the marking mark and the pulley, the marking The strokes are blurred, which is easy to cause reading errors; the electric bell and stopwatch are used to measure the flow rate, which is not only time-consuming and laborious, but also increases the test duration, and is prone to signal error and stopwatch reading error
