Detailed ways

Embodiment one

The ecological power generation system of this embodiment, its structure as shown in Figure 1 and Figure 2, includes a set of diversion canals 1 with a certain slope, runners 2 arranged in the diversion canals 1, and power generating units installed on both sides of the runners 2 device, wherein the slope of the aqueduct 1 is 25°, which can increase the drop of the water flow, and the power generation device includes a speed increaser box 3 and a generator set 4, and the runner 2 passes through the universal support shaft 22 and its bearings arranged on the aqueduct 1 The seat is fixedly installed on the ground on both sides of the water diversion channel 1, wherein the runner 2 is connected with the speed-up box 3 distributed on both sides through the central shaft 21 and the coupling 23 in turn, and the speed-up box 3 is connected with the gear in turn through the connecting shaft. Case 5, generating set 4 are connected. The front end of the aqueduct 1 is provided with a front pool 6, and the tail end is provided with a tail pond 7. An adjustment gate 10 is provided in the aqueduct 1 in front of the runner 2 to adjust the water energy flow in the aqueduct 1.

In actual work, a group of diversion canals are arranged sequentially on the embankment 8 from top to bottom, wherein a water pump 9 is installed in the tail pond 7 of the last diversion canal 1 , and the water outlet of the water pump 9 is set at the front pond of the first diversion canal 1 6, the low water level water flow can be transported to the high water level to facilitate the reuse of water sources, and a trash rack 61 and a gate are set at the water outlet of the front pool 6 of the first diversion canal 1 (see Figure 3). When generating electricity, the water flow from the water source flows from the upper water level into the front pool 6 for storage. After the accumulation reaches a certain water level, the gate is opened to release the water, and the water flows through the artificially built diversion channel 1. At this time, the water head is 1.8-3m, and the water flow flows from the upper water level to the lower water level. The potential energy of the drop can do work, and the runner 2 is driven to rotate at a speed of 2-5m/s to convert water energy into mechanical energy. At the same time, the central shaft of the runner 2 drives the speed-up box 3 on both sides to drive the generator sets on both sides. The rotor of 4 works to convert mechanical energy into electrical energy output.

Except above-mentioned embodiment, the utility model also can have other embodiment. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the utility model.
