Detailed Description

As shown in fig. 1, 2 and 3, the small-size flexible shaft power generation device of rivers self-adaptation includes flotation pontoon 10, flotation pontoon 10 is inside to be fixed with accumulator jar 20, flotation pontoon 10 top fixedly connected with alarm lamp 30, alarm lamp 30 passes through the wire and connects in accumulator jar 20, flotation pontoon 10 is inside still to be equipped with dc generator 40, dc generator 40's rotor coaxial fixation is in flexible axle 50 axle core one end, flexible axle 50 axle core other end axle core coaxial fixation is in impeller 60 center, dc generator 40 passes through the wire and connects accumulator jar 20.

Particularly, including plastics flotation pontoon 10 (adopt the sealed shell of flotation pontoon), warning light 30 (adopt LED) is installed at flotation pontoon 10 top and can install the switch through wire (can install on the wire) and be connected to the accumulator jar 20 in flotation pontoon 10 middle part inner chamber, flotation pontoon 10 is located accumulator jar 20 below and still is equipped with DC generator 40's installation cavity, this installation cavity is equipped with the outside vertical decurrent through-hole of intercommunication flotation pontoon 10, the setting of DC generator 40 rotor below the flotation pontoon is faced, DC generator 40 can be connected with the rotor shaft through the connecting rod and extend to flotation pontoon 10 lower bottom and 50 one end fixed connection of flexible axle (accessible universal joint), the 50 other end of flexible axle passes through-hole back connection fixed connection (can direct welded fastening or bolt fastening) in impeller 60 center, DC generator 40's output current end passes through wire fixed connection in order in time to charge accumulator jar 20 in accumulator jar 20.

Further, the impeller 60 includes a central column 601 and a plurality of blades 602 uniformly fixed along the circumference of the central column 601, one end of the blade 602 is fixedly connected to the central column 601, the other end is fixedly connected to the inner wall of the air guide sleeve 603, and the shaft core of the flexible shaft 50 is fixedly connected to the shaft center of the central column 601. Through fixing both ends of the fan blade 602 with the center post 601 and the air guide sleeve 603 respectively, the water flow impacting the fan blade 602 can make the impeller 60 integrally rotate due to the better convergence of the air guide sleeve 603, so as to drive the direct current generator 40 to rotate through the flexible shaft 50.
