Waterpower secondary electricity generation unit
Technical field
The utility model relates to a kind of waterpower secondary electricity generation unit, and it belongs to a kind of equipment that utilizes reservoir impoundment power generation.
Background technique
The present hydroelectric power unit of China all is only the retaining resource once to be utilized, and build the dam, the barrage investment is big, only utilizes the retaining resource one time, investment and regenerated resources is existed the shortcoming of serious waste.
Summary of the invention
The purpose of this utility model is the serious technological difficulties of the waste resource of the existing hydroelectric power unit existence of solution and a kind of waterpower secondary electricity generation unit that can make full use of retaining resource and saving investment is provided.
The utility model for the technological scheme that solves above-mentioned technological difficulties and adopt is: waterpower secondary electricity generation unit, comprise hydroelectric generator No. one time, wherein: it also comprises drainage trough, by water turbine, main shaft, the secondary hydroelectric generator that frame and generator constitute, the upper end of drainage trough is connected with the water outlet of a hydroelectric generator, the lower end of drainage trough is connected with the water intake of water turbine, main shaft is located on the frame of unit, one end of main shaft is connected with water turbine, the other end of main shaft is connected with generator, and the secondary hydroelectric generator is located at the following of a hydroelectric generator and will forms drop.
Because the utility model has adopted technique scheme, at a generator set water outlet place drainage trough is set, the current after the generating are for the first time introduced in the water turbine of secondary electricity generation unit, drive generator and carry out secondary electricity generation.Therefore, compare, the utlity model has advantages such as to make full use of retaining resource and saving investment with background technique.
