Problems solved by technology

At present, most of the power generation equipment on the market is generally used for dams with high flow rate and high water head, but they are huge in size and inconvenient to carry
For dams with a certain flow rate, only the number of turbines can be fixed, and the assembly cannot be flexibly changed according to the flow rate.
To sum up, the current market lacks a flexible, convenient and efficient power generation device for water flow with small flow rate and low head.

Embodiment

[0071] A stepped distributed power generation device can be applied to water conservancy and hydropower projects, acting on the surface of an overflow surface.

[0072]In the distributed power generation device, the vertical stepped steel plate 3-2 is perpendicular to the horizontal steel plate 3-1 in the initial state and is in a closed state. In the control system, the initial state of the movable slider 14 is the far end in the 90° slide rail 7 .

[0073] In the control system, the maximum swing angle of the swing motor 8 is controlled through the 90° slide rail, so that the vertically stepped steel plate 3-2 achieves the expected 90° flip. The swing motor 8 connects the slide block 14 through a steel rod, and the other side connects the slide block 14 and connects the hinged bearing 6 through the connecting rod 23 and the tunnel moving rod 24 . Two cylindrical wheels 15 are respectively placed at the grooves on both sides of the 90° slide rail. The main purpose of this is...

Abstract

The invention belongs to the field of hydroelectric generation, and particularly relates to a step-shaped distributed power generation device and an operation method thereof. The device is arranged on an overflow dam face and comprises a plurality of sets of step-shaped steel plates, distributed power generation mechanisms and a control system, wherein, the plurality of sets of stepped steel plates are distributed in the height direction of the overflow dam face, the plurality of distributed power generation mechanisms are evenly and detachably arranged in each step-shaped steel plate in the transverse direction, and the size of each distributed power generation mechanism is gradually increased along with reduction of the height of the stepped steel plates; and the distributed power generation mechanisms are in a working state and a non-working state through the control system, and when the distributed power generation mechanisms are in the non-working state, the distributed power generation mechanisms are located in a gap formed by the step-shaped steel plates and the overflow dam face. The device can act on a dam with low flow velocity and low water head or an overflow face with certain flow; and the distributed power generation device is flexible and has the advantages of being small, exquisite, convenient in use, capable of being assembled at will according to the width of the overflow face or the flow, high in power generation efficiency and the like.

Description

technical field [0001] The invention belongs to the field of hydroelectric power generation, and in particular relates to a stepped distributed power generation device and an operating method thereof. Background technique [0002] As the concept of low-carbon environmental protection is deeply rooted in the hearts of the people, water, as a renewable clean energy, has also been valued by people for its power generation function. Most of the power generation equipment currently on the market is generally used for high flow rate and high water head dams, but they are huge in size and inconvenient to carry. However, for dams with a certain flow rate, the number of turbines can only be fixed, and the assembly cannot be flexibly changed according to the size of the flow rate. To sum up, there is currently a lack of a flexible, convenient and efficient power generation device on the market for water flow with low flow rate and low head. Contents of the invention [0003] The p...
