Self-supported power generation device

Abstract

A self-supported power generation device is installed in a high building having multiple floors to realize self-supported power supply of low power and simplified arrangement. Water reservoir is arranged in a floor-spaced manner by tanks set in different floors. Each tank has a conic converged lower section forming a discharge opening coupled to a power generator unit that is driven by vanes to generate electrical power. Thus, by the water head supplied from each tank to drive the vanes for rotating the power generator unit, and with a vertical stacked manner of the multiple sets of power generator units and tanks, a multi-floor water-weight-driven power generation assembly is established. A water collection reservoir is provided at the bottommost location to collect the water for cyclic use. Thus, self-supported power generation for self-supported supply of power of a building is realized and environmental protection and healthy concerns are also satisfied.

1 . A self-supported power generation device, comprising water reservoir tanks and generator units, wherein the water reservoir tanks are separately and respectively arranged on different floors of a building to form a floor-spaced water reservoir system, each tank having a bottom forming conic converged section to serve as means for speed increasing for a water flow discharged from a discharge opening in the bottom of the tank to thereby allowing the water flow to drive rotation of vanes arranged under the bottom of the tank, the rotation of vanes being transmitted through a transmission and speed-increasing means so that low rotational speed of the vanes is converted into high speed of the respective power generator to generate electrical power, the tank that is arranged on a next floor being located below the vanes and coupled to the vanes by piping to guide the water flow toward the tank of the next floor, which is also provided with a conic converged discharged opening to guide the water to drive vanes of the next floor for power generation, wherein the water is so guided to sequentially flow through all the different floors to carry out the power generation operation and is eventually collected in a bottommost collection reservoir to completely recover the water used to generate power, the water being pumped by pumping means to a topmost reservoir for cyclic use for power generation to thereby effect continuous power generation. 
     
     
         2 . The self-supported power generation device as claimed in  claim 1 , wherein the power generators are selectively added or removed on the basis of practical needs in accordance with addition or removal of the tanks to thereby change capacity of power generation. 
     
     
         3 . The self-supported power generation device as claimed in  claim 1 , wherein the power generator units and the water tanks are arranged in a floor-spaced manner in a basement of a building. 
     
     
         4 . The self-supported power generation device as claimed in  claim 1 , wherein the floor-spaced arrangement is provided with a power distribution means to distribute the electrical power generated. 
     
     
         5 . The self-supported power generation device as claimed in  claim 1 , wherein the water tank is arranged at an upper floor while the power generator unit is arranged at a lower floor and connected to the water tank with piping in order to realize potential based power generation. 
     
     
         6 . The self-supported power generation device as claimed in  claim 1 , wherein the power generator comprises an axial-flow type or inclined-impact type hydraulic power generation device. 
     
     
         7 . The self-supported power generation device as claimed in  claim 1 , wherein the self-supported power generation device is arranged in a sectionized manner based on the floors of the building so that each section is self-supported for power generation and supply.
