Embodiment
Below in conjunction with accompanying drawing, illustrate the utility model.
Referring to Fig. 1-Fig. 4, the utility model comprises counterweight 103, valve 102 and electric control box 101.Electric control box 101 is fixed on working platform 115, and counterweight 103, valve 102 are positioned at electric control box 101 casings, and electric control box 101 tops are provided with electrical control circuit.Electrical control circuit comprises power supply 111, switch 109 and lifting motor 108, affixed pulley 110 on the output shaft of lifting motor 108, and pulley 110 is connected with valve 102 by hawser 104.Electric control box 101 bottoms are provided with bar shaped hole slot 113, for water inlet.Electric control box 101 casings are provided with regulator hole 114.
Working procedure is as follows:
Wave enters electric control box 101 inside by the hole slot 113 of electric control box 101 bottoms, and water level rises gradually, and when water level reaches designated water level, switch 109 is communicated with, lifting motor 108 energisings.The output shaft band movable pulley 110 of lifting motor 108 rotates, and pulley 110 is by hawser 104 poppets 102.
When hawser 104 is promoted to spacing ball 105 and contacts with longitudinal spacing bar 106, hawser 104 drives counterweight 103 to rise simultaneously, until rise to longitudinal spacing bar 106, contacts with electric control box top box plate 112.
Water level declines, water level drop to setting close water level time, switch 109 disconnects, lifting motor 108 power-off.Water level decline buoyancy reduces, and counterweight 103 falls after rise under the effect of gravity, and meanwhile, valve 102 is followed counterweight 103 and fallen after rise under the effect of spacing ball 105.
