Buffer for tidal stream generation apparatus

A generating apparatus for converting kinetic energy from a water flow to electrical energy, comprising:

• a housing comprising a front plate, a rear plate, two side plates, a top plate, a bottom plate, an inlet disposed through the front plate for flowing sea water into the housing, an outlet disposed through the rear plate for flowing sea water out of the housing, a first gate disposed at the inlet, a first activation device disposed at the inlet for opening or closing the first gate, a second gate disposed at the outlet, and a second activation device disposed at the outlet for opening or closing the second gate;
• a kinetic energy collecting device disposed in the housing and comprising a shaft, two pivots at two ends of the shaft pivotably secured to the side plates respectively, a waves breaking board extended downward from the shaft to dispose between the inlet and the outlet, an impact rod extended rearward from the shaft, and a projection disposed at a rear end of the impact rod wherein length of the impact rod is greater than height of the waves breaking board;
• a set of pulleys disposed in the housing and comprising a first connecting rod having two ends fastened in the side plates respectively, a movable pulley disposed on an intermediate portion of the first connecting rod, a second connecting rod having two ends fastened in the side plates respectively, a fixed pulley disposed on an intermediate portion of the second connecting rod, a rope having a first end secured to the rear end of the impact rod, the rope passing over the movable pulley and the fixed pulley to have a second end secured to a counterweight, and a guide tube with the counterweight movably disposed therein;
• a shock absorbing assembly disposed under the fixed pulley and above the counterweight, the shock absorbing assembly comprising a support plate having two ends secured to the side plates respectively, a hole disposed through the support plate with the rope passing through, and a plurality of biasing members facing the counterweight and disposed externally of the hole;
• a tidal stream generator comprising an energy storage device disposed on the front plate, an electricity generation device disposed on the energy storage device and facing the kinetic energy collecting device, and an elastic member disposed on the electricity generation device;
• and
• a control device disposed on the front plate and comprising a rechargeable battery electrically connected to the tidal stream generator and configured to store electricity, a wireless receiver electrically connected to the rechargeable battery, and a water level sensor electrically connected to the rechargeable battery.
