Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic power generation, and specifically refers to a hydraulic power generation device for river ecological landscape. Background Art

[0002] A hydraulic power generation device is a device that converts the kinetic energy of water flow into mechanical energy and then into electrical energy through a generator. As a clean and renewable energy form, it occupies an important position in the energy structure. With the increasing attention of society to environmental protection and sustainable development, hydraulic power generation devices have also been widely used in the construction of river ecological landscapes.

[0003] However, existing hydraulic power generation devices often neglect the impact of water level changes on power generation efficiency during design. The water level in the river is affected by various factors such as seasons, climate, and rainfall, showing obvious change characteristics. When the water level rises, the water flow velocity increases, but too high a water level may cause the power generation device to be overloaded and even pose safety hazards; while when the water level drops, the water flow velocity slows down, and the power generation efficiency will decrease significantly.

[0004] In addition, existing hydraulic power generation devices lack flexibility in adapting to water level changes and cannot automatically adjust the power generation power according to the water level changes, resulting in low energy utilization efficiency. At the same time, this lack of adaptability in design also does not meet the overall requirements of river ecological landscape construction and cannot achieve a win-win situation between ecology and power generation benefits. Content of the Utility Model

[0005] In order to solve the problem that existing hydraulic power generation devices often neglect the impact of water level changes on power generation efficiency during design, the utility model proposes a hydraulic power generation device for river ecological landscape.

A rolling shaft is sleeved on the bearing two. Stirring blades are annularly arranged on the rolling shaft. A linkage shaft is provided at one end of the rolling shaft. A power generation device is provided at the other end of the linkage shaft.

[0007] Further, the elevating frame is slidably and internally connected to the cross block. A bearing one is provided on the elevating frame. A lead screw is provided on the bearing one. The lead screw is internally connected to the cross block. The lead screw is threadedly connected to the cross block.
