Hydroelectric generating set and dam power generation system

Abstract

The invention discloses a hydroelectric generating set which comprises a cylindrical water cylinder with a water inlet and a water outlet, a water conduit, a water wheel, a water outlet pipe and a generating set, wherein the water conduit is connected with the water inlet of the water cylinder, the water outlet pipe is connected with the water outlet of the water cylinder, the water conduit is vertically arranged in the tangent direction of the water inlet of the water cylinder, and the extension line of the water conduit is vertical to the extension line of the water outlet pipe; and the water wheel is arranged in the water cylinder and is coaxially connected with the generating set at the outside. The invention provides the hydroelectric generating set and a dam power generation system and provides a dam power generation building structure and a more effective water injection mode, therefore, the water has much more free falling movement potential energy, and the geopotential energy guarantees strong water turbine power, small water requirement for acting and high mechanical efficiency.

Description

technical field [0001] The invention relates to the field of hydroelectric power generation engineering, in particular to a hydroelectric power generation device and a dam power generation system. Background technique [0002] 1. The existing turbines are only suitable for storage capacity hydropower generation, but not waterfall hydropower generation. Waterfalls are widely distributed in my country and even around the world, with large water level drop and strong water potential energy. The development of waterfall resources and the use of waterfall hydropower generation will greatly provide Clean energy, alleviating energy shortage and reducing air pollution are of great strategic significance. [0003] 2. Existing turbines are built inside the dam body, which uses the pressure force of water to generate kinetic energy, and the force of the water in the dam body is decomposed: one is the pressure force, the other is the vertical downward gravity, and the vertical force The...

Problems solved by technology

[0004] 3. The existing water turbines are all built in the dam body, which causes the dam body to form many huge cavities and destroys the integrity of the dam body. Such a hollow dam body structure highlights the fragility of the dam body. , it is necessary to increase the width of the dam body, increase the amount of cement, stone, and steel, increase the project cost and cost, and extend the project period

[0005] 4. The existing water turbine does not have a water flow control device and a gearbox system. The water turbine rotates at a high speed and has a large displacement. The high speed results in a high water flow velocity. The water discharged after doing work is like a galloping horse. waste of water

[0006] 5. The existing hydraulic turbines are all built in the dam body, and the number of hydroelectric generating units is restricted by the space of the dam body, which will not form a scale attitude of hundreds or thousands of generating units, which greatly limits the power generation

[0007] 6. The existing water turbines are all built in the dam body, which is very inconvenient for the installation and maintenance of the water turbines
