Water flow speed increasing device for bulb tubular generator set

Abstract

The invention relates to a water flow speed increasing device for a bulb tubular generator set. The device comprises a speed increasing tube, at least four drainage plates, a guide plate and at least four speed increasing plates. The speed increasing tube is in a hollow truncated pyramid structure, a water inlet is formed in the lower bottom, a water outlet is formed in the upper bottom, and the at least four drainage plates are arranged on the tube wall of the water inlet and the water outlet and are hinged to the tube wall of the speed increasing tube. An angle adjusting mechanism is further arranged, and the guide plate is disposed in the speed increasing tube and is perpendicular to the inner wall of the speed increasing tube and distributed along the axial direction of the speed increasing tube. The at least four speed increasing plates are connected with the inner wall of the speed increasing tube and are distributed in the same horizontal plane. Each of the speed increasing plates comprises a compression plate and a pressure relief plate. According to the device, functions of speed increasing active adjusting and active drainage and guide of water flows are provided, and accordingly, water flow speeding up is facilitated, irregular impact of turbulence and the like on subsequent generator sets is prevented, and the generator operation stability is improved.

[0002] When using hydropower to generate electricity, the flow rate and direction of the water flow directly play a decisive role in the working efficiency and operating state of the generator, especially in the case of bulb tubular power generation This phenomenon is more obvious when the unit is generating electricity. In order to improve the power generation efficiency of the generator and the stable operation of the generator set, the current common practice is to install a water flow speed-up device at the front of the generator. However, in use, it is found that most of the water flow speed increasing devices currently used are trumpet-shaped structures, which are fixed in structure and do not have flexible adjustment capabilities, so their ability to guide water flow is relatively weak, and when adjusting water flow On the other hand, it can only operate at a fixed ratio without any adjustment capability, which greatly reduces the flexibility of its use, and ultimately leads to its weak water flow growth rate, which cannot effectively meet the needs of actual use.
