Embodiment 1

[0049] In this embodiment, the vertical submersible blade variable-angle hydroelectric generating set has a structure such as Figure 1 to Figure 4 As shown, a main support 1 is included, and the main support 1 includes a support base 1-1, a mounting plate 1-2 vertically installed on the support base 1-1, and a reinforcement plate 1 vertically installed on the back of the mounting plate 1-2 -3, wherein the support base 1-1 is combined with the reinforced concrete foundation at the bottom of the river to carry the unit. Mounting plate 1-2 is provided with U-shaped guide rail 7 extending along its length direction and lifting rack 11, and lifting rack 11 is meshed with the gear of lifting gear box 10, and lifting gear box 10 links to each other with lifting motor 9, in Driven by the lifting motor 9, the gear of the lifting gear box 11 moves up and down along the lifting rack 11, thereby driving the rectangular deck 1-4 installed in the U-shaped guide rail 7 to move up and down a...

Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that in order to solve the problem that the negative water facing surface 2-10 of the blade 2-3 in the static fixed blade water wheel assembly has a large resistance in water, a "flexible blade" is proposed. technology", such as Figure 12 and Figure 13 As shown, the flexible blade is divided into two parts, the two parts include the blade tip section 2-3-3 and the blade bottom section 2-3-2, the blade bottom section 2-3-2 and the blade tip section 2-3-3 There are three living hinges 2-3-4 evenly distributed along the height direction between the ends of the two. One end of the first hinge is hinged with the hinge seat, the other end of the first hinge is fixed on the water facing surface of the blade bottom section 2-3-2, and the other end of the second hinge is fixed on the blade tip section 2-3-3 On the facing water surface, the blade bottom section 2-3-2 is hinged with the blade tip section 2-3-3 through ...

Embodiment 3

[0058] The difference between the present embodiment and the second embodiment is that the blade variable-angle hydro-generator set of the present embodiment is a portal-type semi-submersible horizontal-axis generator set, and its structure is as follows Figure 16 , 17As shown, the left and right main brackets 1 (the structures of the left and right main brackets 1 are the same as in Embodiment 1) that are arranged in mirror image are included, and the upper ends of the left and right main brackets 1 are connected by bracket beams 14 to form a portal structure. The upper ends of the rectangular decks 1-4 of the left and right main brackets 1 are all fixed on the equipment beam 13, and the lower ends are respectively fixed with water wheel main shaft bearing seats 8, and on the equipment beam 13, in addition to a speed regulator 3 and a generator 4. The lifting motor 9 and the lifting gear box 10 are also installed. The water wheel assembly 2 is horizontally arranged between t...

Abstract

The invention relates to a blade variable-angle type water-turbine generator set for a river. The blade variable-angle type water-turbine generator set for the river comprises a main bracket, wherein a water turbine assembly, comprising a main shaft and a blade seat which fixedly sleeves the main shaft, is mounted on the water turbine assembly; a group of blades which axially extend is circumferentially uniformly distributed on the outer circumferential surface of the blade seat; each blade is hinged with the blade seat and can open or contract by angles relative to the blade seat; a shaft hole is formed in the upper end of the root part of each blade, and a blade angle adjusting shaft which is fixedly sleeved with a blade angle adjusting gear is fixedly arranged in each shaft hole; a blade angle adjusting rack seat is movably connected on the main shaft and above the blade seat in a sleeving manner; the blade angle adjusting rack seat is fixedly connected with the main bracket; blade angle adjusting racks which can be engaged with the blade angle adjusting gears are arranged on the blade angle adjusting rack seat. The blade variable-angle type water-turbine generator set for the river has the advantages that the water resource energy, including large water yield, fast flowing speed and large water mass potential energy, of the river is utilized; a dam constructed for storing water is saved; a traditional dam type water-turbine set technology is saved; and the power can be generated without other mechanical power and chemical energy.

Description

technical field [0001] The invention relates to a generator set, in particular to a blade variable-angle hydraulic turbine generator set used in rivers and rivers, and belongs to the technical field of power generation equipment. Background technique [0002] Hydropower is a renewable, energy-free, green and clean energy that does not produce carbon dioxide and other environmental pollution, so it is strongly advocated by the state. [0003] Traditional hydroelectric power generation is to use the drop of water to impact the blades of the water turbine to drive the generator to generate electricity, and convert the potential energy into electrical energy. Its technical characteristics are closely related to water flow and water drop. The greater the water flow, the greater the water drop, and the greater the amount of electricity that can be generated. In the existing technology and practice, in order to achieve large water volume and large drop, water conservancy dams are...
