Crushing power generator

Abstract

A crushing power generator is capable of being installed below a road surface. The crushing power generator includes a hollow casing installed below a road surface and having an upward opening; a resetable pressing unit installed in the hollow casing and part of the resetable pressing unit protruded out of the hollow casing from the opening the hollow casing for receiving pressure from the road surface to descend into the hollow casing so as to generate a downward pressure; a generator unit received in the hollow casing; and a power converter received in the hollow casing and connected to the resetable pressing unit and the generator unit so as to convert the downward pressure from the resetable pressing unit into mechanic power to drive the power generator unit to generate power.

         5 . The crushing power generator as claimed in  claim 4 , wherein the resetable pressing unit includes a roller set having a connecting rod and two rollers at two ends of the connecting rod; one end of the connecting rod is approximately connected to the first end of the first inclined plate and has a roller; another end of the connecting rod faces toward the hollow casing and is connected with another roller; the resisting plate is connected at one end of the driving shaft and is in contact with the roller; the elastic element is a spring enclosing the driving shaft and is placed between the resisting plate and the spacer; when the first inclined plate and the second inclined plate are pressed, the second ends of two plates are pivotally rotated downwards to drive the roller set to push the driving shaft to moves downwards so that the pressure cylinder can output pressure. 
     
     
         6 . The crushing power generator as claimed in  claim 3 , wherein the power converter further includes a tube set and a pressure motor; the pressure motor is connected to a power generator unit through a speed change unit so that the output pressure from the pressure cylinder is transferred to the pressure motor through the tube set to drive the pressure motor to generate mechanic power; the generator is driven by the mechanic power to generate electric power. 
     
     
         7 . The crushing power generator as claimed in  claim 6 , wherein the pressure motor is an air compressing motor; and the tube set includes an air pressure tubes connected to the pressure cylinder and the air compressing motor. 
     
     
         8 . The crushing power generator as claimed in  claim 6 , wherein the pressure motor is an oil pressure motor and the pressure cylinder is an oil pressure cylinder; the tube set are oil tubes connected the oil pressure cylinder and the oil pressure motor. 
     
     
         9 . The crushing power generator as claimed in  claim 6 , wherein the power converter includes a gear change unit connected the power generator unit and the pressure motor for converting mechanic power from the pressure motor to be transferred to the power generator unit. 
     
     
         10 . The crushing power generator as claimed in  claim 2 , wherein the power converter includes a rack and an unidirectional gear set and a driving shaft; a top of the driving shaft is located below the connection of the first inclined plate and the second inclined plate; the rack is located at a lower end of the driving shaft; the unidirectional gear set is installed at the power generator unit and is engaged to the rack at the lower end of the driving shaft; when the first inclined plate and the second inclined plate are pressed downwards, the driving shaft is pushed downwards to drive the rack to rotate the unidirectional gear set so that the power is transferred to the power generator unit to drive the power generator unit to generate power. 
     
     
         11 . The crushing power generator as claimed in  claim 1 , wherein the power generator unit is an induction power generator. 
     
     
         12 . The crushing power generator as claimed in  claim 11 , wherein the power generator unit further includes a battery set for storing power from the generator. 
     
     
         13 . The crushing power generator as claimed in  claim 3 , wherein the power converter further includes a pressure storage device for storing pressure from the power converter.
