Abstract
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...

Embodiment Construction
[0012] The present invention will be further explained below in conjunction with the drawings.
[0013] Such as figure 1 As shown, the automatic control device for marine flow test according to the present invention includes a measuring vessel 7, a power part 4, and a control part 11. The power part adopts an integrated structure of a motor, a reducer and a brake, and the reducer drives the intermediate transmission through a belt Wheel 5 and tension wheel 6, the intermediate transmission wheel 5 drives the drum 3. One end of the lifting loop 9 is fixed on the drum, the lead fish 10 is fixed on the other end of the lifting loop 9, the base 1 is placed on the survey ship, and the bottom plate 12 is fixed on the base , The bottom plate is installed with the winch frame 2, the power unit and the control device are installed on the bottom plate 12, and the drum 3 is installed on the winch frame. The control part includes a hydrological winch controller, a flow rate recorder, and...
