Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] Such as figure 1 , figure 2 , image 3 As shown, a hydroelectric generating unit of the present invention includes a generator, a water turbine 1 and an installation platform 2. The installation platform 2 is generally formed by pouring cement, and is generally called the ground of a hydroelectric turbine room in a hydropower station. The bottom surface is composed of several layers of poured cement boards. The installation platform 2 has two levels of flat panels, the lower level flat panel is used to install the water turbine 1, and the upper level flat panel is installed with a generator base 4 and a bearing box; the generator and the water turbine 1 are respectively installed on the top and bottom of the installation platform 2; Bolts can be installed; the generator is a permanent magnet direct drive hydraulic generator 3; a gener...

The invention discloses a water-turbine generator set which comprises a power generator, a water turbine (1) and a mounting table (2), wherein the power generator and the water turbine (1) are respectively mounted at the upper part and the lower part of the mounting table (2); the power generator is a permanent magnetic direct driving hydraulic power generator (3); a power generator base (4) which is mounted on the mounting base (2) is further arranged between the permanent magnetic direct driving hydraulic power generator (3) and the water turbine (1); the permanent magnetic direct driving hydraulic power generator (3) is mounted on the power generator base (4); a bearing box is arranged in the power generator base (4); the output shaft and the input shaft of the bearing box are respectively connected with the input shaft of the permanent magnetic direct driving hydraulic power generator (3) and the output shaft of the water turbine (1); a main shaft water resistor is further arranged on a shaft hole between the bearing box and the water turbine (1). The water-turbine generator set is high in power generation efficiency.
Description
technical field [0001] The invention relates to a device for converting water energy into electric energy, in particular to a water turbine generator set. Background technique [0002] The hydroelectric generating set of the prior art comprises a synchronous generator, a water turbine and an installation platform formed by pouring cement, and the synchronous generator and the water turbine are all installed on the installation platform; the power input shaft of the synchronous generator, the water turbine The power take-off shafts are all connected by couplings. When in use, the water flow drives the runner of the water turbine to rotate, and then drives the generator to generate electricity. The hydroelectric generating set with the above structure has the following disadvantages in the actual use process: the water head of the hydropower station will constantly change in different seasons. The efficiency of the water turbine is the highest at the optimal speed correspond...
