Detailed Description
The invention is further illustrated by the following figures and examples.
The straight-flow type side-edge deflection discrete water turbine shown in fig. 1 and fig. 2 comprises a support, a rotor and a plurality of flow-blocking directional discrete baffles, wherein the rotor is mounted on the support through a rotating shaft, the flow-blocking directional discrete baffles are mounted on the support, and all the flow-blocking directional discrete baffles are uniformly distributed relative to the circumference of the axis of the rotating shaft; the rotor comprises a rotor main body and a plurality of guide vanes, the rotor main body is arranged on the bracket through a rotating shaft, one end of the rotor main body is provided with a water inlet, the guide vanes are arranged on the rotor main body, the guide vanes are uniformly distributed relative to the circumference of a central shaft of the rotor main body, and a space is reserved between every two adjacent guide vanes to form a water outlet; the rotor main body and all the guide vanes form a rotor inner cavity communicated with the water inlet and the water outlet; the water outlet faces the flow-resisting directional discrete baffle. Specifically, water flow enters the inner cavity of the rotor from the water inlet and then flows out from the water outlet, so that the rotor is pushed to rotate, and the energy of the water flow is converted into mechanical energy. The water outlet of the straight-flow type side deflection discrete water turbine is composed of guide vanes which are uniformly distributed on the circumference of the rotor main body to form a circular tangent water outlet, when water flows out of the water outlet, circular tangent water flow can be formed, thrust is generated by the circular tangent water flow to enable the rotor to rotate, further, the circular tangent water flow forms reverse counter-current under the action of the flow-blocking directional discrete baffle, and therefore the maximum counter-thrust is provided for the circular tangent water flow, and the efficiency of converting water energy into mechanical energy is improved.
As shown in fig. 2 and 3, the guide vane comprises a first tangent guide section, a second tangent guide section and a discrete guide section, the first tangent guide section, the second tangent guide section and the discrete guide section are sequentially connected, and the angle between the second tangent guide section and the discrete guide section is a, wherein a is greater than or equal to 90 degrees and less than or equal to 135 degrees; in 2 adjacent guide vanes, the extension lines of the first tangent guide section of 1 guide vane and the second tangent guide section of the other 1 guide vane can fall on the same flow-resisting directional discrete baffle. The guide vane is arranged into three sections, namely a first tangent guide section, a second tangent guide section and an off-line guide section, which are sequentially connected with one another, so that the direction of the water outlet is the direction of a circular tangent, and the water flow flowing out of the water outlet is ensured to form the circular tangent water flow. And an angle a is formed between the second tangent line guide section and the discrete flow guide section, so that the water in the inner cavity of the rotor can smoothly flow to the water outlet, and the effective operation is ensured. In 2 adjacent guide vanes, the extension lines of the first tangent guide section of 1 guide vane and the second tangent guide section of the other 1 guide vane can fall on the same flow-resisting directional discrete baffle, so that the circular tangent water flow can obtain the optimal reverse thrust, and the conversion rate of water energy is further improved.

The cross section of the flow-resisting directional discrete baffle is L-shaped. The cross section of the flow blocking directional discrete baffle is not limited to the above, and an arc-shaped or straight-line plate can be adopted, so that the flow blocking directional discrete baffle can block the circular tangent water flow flowing out of the water outlet. In the embodiment, the L-shaped cross section is adopted, so that a small number of flow-blocking directional discrete baffles can be adopted to block all water flows at the water outlet, the installation can be simplified, and the cost is saved.
