Abstract

The invention discloses an adjustable impeller structure and hydroelectric equipment. The adjustable impeller structure comprises a shell and a rear cover detachably connected with the shell, and further comprises a plurality of blades, a rotating shaft penetrating through the side wall of the shell is fixed to the side, facing the shell, of each blade, a first bevel gear is fixed to the end, awayfrom the corresponding blade, of each rotating shaft, the first bevel gears are engaged with a second bevel gear rotationally mounted on the rear cover, and the second bevel gear is connected with anadjusting mechanism arranged on the outer side of the shell. A limiting disc is further installed on each rotating shaft, a plurality of limiting holes are formed in each limiting disc, and the limiting holes are matched with a clamping pin assembly arranged on the rear cover. The adjusting mechanism is separated from the rear cover, the clamping pin assembly is automatically separated from the limiting holes at the moment, the arranged adjusting mechanism drives the second bevel gear to rotate, and when the second bevel gear rotates, the rotating shafts and the blades connected with the rotating shafts are driven to rotate through rotation of the first bevel gears engaged with the second bevel gear, so that the placement angles of the blades are changed.

Description

Technical field[0001]The invention relates to the technical field related to hydropower generation, in particular to an adjustable impeller structure and hydropower generation equipment.Background technique[0002]Hydropower is the science and technology that studies technical and economic issues such as engineering construction and production operations that convert water energy into electrical energy. The water energy used by hydropower is mainly the potential energy stored in the water body. In order to convert water energy into electricity, different types of hydropower stations need to be built.[0003]Using rivers, lakes and other water with potential energy located at a high place to flow to a low place, the potential energy contained in it is converted into the kinetic energy of the water turbine, and then the water turbine is used as the driving force to drive the generator to produce electricity. Use hydraulic power (having a head) to push a hydraulic machine (water turbine) t...
