Problems solved by technology

However, hydroelectric power generation requires the construction of dams to concentrate the water flow drop. On the one hand, the investment is huge and the construction period is long. On the other hand, the natural river must be artificially cut off, which has a certain impact on the ecological environment. The reservoir area may flood fertile fields, forests and Cultural facilities such as historical sites can affect the life and reproduction of fish, and even cause relocation of immigrants

Embodiment 1

[0031] The structure of the hydroelectric power plant that does not cut off the river course in this embodiment is as follows: Figure 1-2 , Figure 4-5 As shown, it includes a force transmission shaft 1 installed on both banks of the river channel 4 through a supporting device and several blades 2 installed on the force transmission shaft. The power transmission shaft is installed across the river bank 3 in a manner perpendicular to the direction of water flow. , and the two ends are respectively connected with the transmission device in the generator set 4 on the slopes on both banks of the river channel; The blade surface is a blade surface with a symmetrical structure shape. The blade is installed on the force transmission shaft through the installation hole so that the direction of the symmetrical plane of the blade surface on the left and right sides of the blade is at an angle of 30° with the direction of the water flow. The flow velocity on one side blade is greater t...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is: the blade surfaces on the left and right sides of the blade are designed as asymmetrically shaped blade surfaces, so that the streamline of the streamlined blade surface on the left side of the water flow direction is longer than that on the right side of the water flow direction, so that the water flow flows through The flow velocity on the left leaf surface of the blade is greater than that on the right leaf surface, and the static pressure of the water flow acting on the surface of the high flow velocity side of the blade surface is smaller than the static pressure acting on the surface of the low flow velocity side. The thrust in one direction provides the required mechanical power for the generating set through the power transmission shaft. At this time, the design can be simulated according to the shape of the shorter side of the streamline and the symmetrical side to obtain the central circle, which can b...

Abstract

The invention provides a hydraulic electric generation power device with a river channel not cut off. The hydraulic electric generation power generation device comprises at least one force transmission shaft stretching across the river channel and installed on both sides of the river channel through supporting devices, and multiple blades installed on the force transmission shaft. The force transmission shaft is located at the position, enabling the blades installed on the force transmission shaft to be located in water flow in the river channel, in the river channel. At least one end of the force transmission shaft is connected with a transmission device installed in a power generator set on the river bank. The blade profiles of the blades are equal in width in the water depth direction,the blade faces on the left side and the right side are streamline curved faces in the water flow direction, when water flow flows through the blades, the flowing speed on the blade faces of one sidesis larger than that of the blade faces on the other sides, the pressure difference is formed by the pressure of the blade faces of the two sides of each blade, and needed mechanical power is providedfor the power generator sets through the force transmission shaft. By means of the hydraulic electric generation power device with the river channel not cut off, hydraulic electric generation can becompleted on the premise that the natural river channel is not cut off, and therefore the phenomenon that the river is cut off, a reservoir is formed, and therefore adverse effects are caused on the ecological environment, animals, plants, natural sand conveying and the like is avoided.

Description

technical field [0001] The invention belongs to the technical field of hydroelectric power generation in water conservancy and hydropower projects, and in particular relates to a hydroelectric power generation device that does not cut off a river course. Background technique [0002] Hydropower generation is the use of rivers and other water with potential energy in high places to flow to low places, convert the potential energy into kinetic energy of water turbines, and then use the water turbines as the driving force to drive generators to generate electricity. Since the water flow is continuously circulated according to a certain hydrological cycle, it is renewable as an energy source. Hydropower only uses the energy carried by the water flow without consuming other power resources, and the water flow used by the upper-level power station can still be used for the next-level power station. Utilization, the cost of power generation is low, and can provide cheap and clean e...
