Change and change, by outside wave effect, it is to avoid corrugated rises and falls the interference to tidal level monitoring.The method also need to be sent out at wave energy
Default control method and action command before water under electric installation, the signal that PLC is produced by logical judgment liquidometer controls spiral lifting
Device carries out corresponding action, drives hydraulic cylinder to adjust to trouble free service position.But use liquidometer monitoring tidal level change to exist as follows
Shortcoming: owing to tide gauge well need to be assembled on wave energy generating set so that device overall structure becomes complicated and intensity decline, easily
Produce malformation even to damage；If stopping state occurs in tide gauge well, the liquidometer monitoring to outside tidal level change will be directly affected,
Helical riser is made to cannot be carried out correct operation；Liquidometer top rosette need to be done waterproof sealing and process, if circuit makes moist or enters
Water also will directly affect liquidometer service behaviour and even result in liquidometer inefficacy.
