Dam-free river-crossing hydraulic power generation device

The invention discloses a dam-free hydraulic power generation device which collects water energy on a big river to generate power under the condition that a dam is not built. The impeller consists of the following parts: 1, impeller frames and impeller discs on two banks; 2, an impeller and blade framework consisting of river-crossing steel wire ropes (or soft ropes which do not absorb water and are made of other materials) (similarly hereinafter); 3, a water baffle consisting of a river-crossing steel wire rope and non-water-absorbing fiber and plastic soft cloth (or a non-water-absorbing light material plate) (similarly hereinafter), namely a water wheel blade; 4, a speed reducer; 5, a generator and a power regulation system; 6, an impeller lifting system; 7, a steel wire rope reinforcing wheel; river water flow collects kinetic energy to rotate when passing through impeller blades jointly formed by river steel wire ropes and fiber plastic soft cloth, impeller discs on the two sides are driven to rotate thr
