Abstract: An onshore hydroelectric power generation device is disposed above a flow to obtain and convert the energy of flow into electricity, comprising a body unit, a water wheel unit, a mobile energy transmitting unit, and an electricity power generating unit. The kinetic energy of the flow is obtained by the water wheel unit, and is transmitted to the power generation unit adapted to the height of water level by the mobile energy transmitting unit.

Abstract: An eye protection device a first covering sheet, a protection sheet, and a second covering sheet. The first covering sheet has a first supporting edge with a containment slot and a first opening disposed on the first supporting edge. The protection sheet is disposed in the containment slot and has a non-transparent sheet and an axial aperture provided in the sheet. The second covering sheet has a second supporting edge and a second opening provided on the second supporting edge. The second supporting edge overlaps the first supporting edge, and the first and second supporting edges sandwich the protection sheet in the containment slot.
