Problems solved by technology

However, with the development of hydropower generation, there are more and more small movable hydroelectric generators. If the blades of this type of generators are also similar to those of large hydropower stations, due to their small weight, they are easily affected by the impact of water flow in all directions. Shake left and right when rotating, which will cause problems caused by the impact of various parts of the impeller, resulting in a short service life of the overall device and high maintenance rate

Embodiment 1

[0028] An impeller for hydroelectric power generation, including an impeller shaft and impeller blades;

[0029] One end of the impeller shaft is connected to the top bearing, the other end is connected to the end bearing, and is coaxially connected to the transmission shaft at the end.

[0030] There are 5 impeller blades, all of which take the entire length of the impeller shaft as the contact part and extend outward in an arc shape, and the width of each impeller blade gradually increases from the top of the impeller shaft to the width at the end of the impeller shaft widest.

[0031] Inside the arc of each impeller blade, a speed reduction plate is arranged in reverse. The speed reduction plate includes a root portion of the speed reduction plate and a head portion of the speed reduction plate. The root portion of the speed reduction plate is fixedly connected to the impeller blade. The width of the root of the speed reduction plate is greater than the width of the head o...

Embodiment 2

[0040] Such as Figure 1~Figure 3 shown.

[0041] An impeller for hydroelectric power generation, including an impeller shaft and impeller blades;

[0042] One end of the impeller shaft is connected to the top bearing, the other end is connected to the end bearing, and is coaxially connected to the transmission shaft at the end.

[0043] There are 3 impeller blades, all of which take the entire length of the impeller shaft as the contact part and extend outward in an arc shape, and the width of each impeller blade gradually increases from the top of the impeller shaft to the width at the end of the impeller shaft widest.

[0044] Inside the arc of each impeller blade, a speed reduction plate is arranged in reverse. The speed reduction plate includes a root portion of the speed reduction plate and a head portion of the speed reduction plate. The root portion of the speed reduction plate is fixedly connected to the impeller blade. The width of the root of the speed reduction ...

Embodiment 3

[0060] An impeller for hydroelectric power generation, including an impeller shaft and impeller blades;

[0061] One end of the impeller shaft is connected to the top bearing, the other end is connected to the end bearing, and is coaxially connected to the transmission shaft at the end.

[0062] There are 3 impeller blades, all of which take the entire length of the impeller shaft as the contact part and extend outward in an arc shape, and the width of each impeller blade gradually increases from the top of the impeller shaft to the width at the end of the impeller shaft widest.

[0063] Inside the arc of each impeller blade, a speed reduction plate is arranged in reverse. The speed reduction plate includes a root portion of the speed reduction plate and a head portion of the speed reduction plate. The root portion of the speed reduction plate is fixedly connected to the impeller blade. The width of the root of the speed reduction plate is greater than the width of the head o...

Abstract

The invention relates to a hydropower impeller. The hydropower impeller comprises an impeller shaft and an impeller blades, the shapes of the impeller blades, a speed reducing plate and a noise removal part are set, so that the hydropower generator impeller is stabilized and does not shake in the rotating process, the rotating speed is stable, the collision between the impeller shaft and a bearing and between shafts is greatly reduced, and the stability and the durability of the whole device are greatly improved.

Description

technical field [0001] The invention belongs to the fields of water conservancy equipment and hydropower generation, and in particular relates to an impeller for hydropower generation. Background technique [0002] Water turbine blades for hydropower (water conservancy) power generation can be divided into two categories, one is lateral (similar to lateral wind turbine blades), and the other is turbine blades, both of which can be applied to large hydropower stations. However, with the development of hydropower generation, there are more and more small movable hydroelectric generators. If the blades of this type of generators are also similar to those of large hydropower stations, due to their small weight, they are easily affected by the impact of water flow in all directions. When it is rotating, it shakes left and right, which will cause problems caused by the impact of various parts of the impeller, resulting in a short service life of the overall device and a high maint...
