The invention relates to a dual-body water conservancy power generation ship. Damming power generation is characterized in that the unit installed capacity is determined by the water flow fall. The dam-free water conservancy power generation ship is characterized in that the unit (ship) installed capacity is determined by traction positioning energy of a traction device. According to the dual-body water conservancy power generation ship, a large traction hanging pile (sunken anchor) and a shore hanging pile (shore anchor) are built at the river bottom to be combined with the power generation ship to form three-dimensional triangular traction positioning, and water flow attacks a unit paddle wheel to convert water flow power into mechanical energy for work doing power generation. In order to improve the installed capacity and effectively reduce dual-anchor loads, dual-anchor-chain hanging points are selectively arranged at the portions of dual-hull-bottom keels to form appropriate angles, so that water flow attacking is converted into upper floating force to reduce resistance. In order to keep the balance of the dual-body ship, the installing space is increased, and the ship building cost is reduced; the flat-bottom dual-body ship is selected. A control system is formed by three anchors and ship-load power so as to keep the transverse level and the longitudinal level of the dual-body ship, and the best water flow is selected through transverse movement positioning. The unit is suitable for working doing power generation in any water flow state through wheel propeller lifting operation.
