Combined type tail water power generation set

Abstract

The invention discloses a combined type tail water power generation set. The combined type tail water power generation set is characterized by comprising a plurality of tail water turbines arranged in parallel and a generator; each tail water turbine comprises a water retaining plate, a water turbine shell body and water turbine bodies; each water turbine shell body comprises two chambers, that is, the first water turbine chamber and the second water turbine chamber, the bottoms of the first water turbine chamber and the second water turbine chamber are in circular arc shapes, the middles of the first water turbine chamber and the second water turbine chamber are provided with the first water turbine body and the second water turbine body, and the inner diameter of the first water turbine chamber is larger than that of the second water turbine chamber; the included angle between first water turbine blades and a blade bracket is 10-45 degrees; each second water turbine body comprises a plurality of second water turbine blades, and the included angle between the second water turbine blades and a blade bracket is 10-45 degrees; and each water turbine rotating shaft is connected with the generator through a driven gear and a speed increasing mechanism. According to the combined type tail water power generation set, the tail water turbines can be arranged and combined at random according to the widths of river channels, using is free and convenient, and in addition, the tail water power generation efficiency is improved.

Description

technical field [0001] The invention relates to the field of tail water power generation equipment, in particular to a combined tail water power generating set. Background technique [0002] Hydropower generation is valued and vigorously developed by various countries for its advantages of no pollution, cleanliness and environmental protection. At the moment when energy is increasingly in short supply, hydropower generation is particularly important. The tail water is wasted in vain, and the utilization of tail water is paid more and more attention by people. Most of the existing tail water power generation devices are simple in structure, the utilization rate of tail water is not high, and the operation is not stable enough, as published in Chinese patent CN 201013525Y A tail water power generation device of a hydropower station, although it can utilize the tail water, has a simple design structure and a low utilization rate of the tail water. In some hydropower stations, ...

[0002] Hydropower generation is valued and vigorously developed by various countries for its advantages of no pollution, cleanliness and environmental protection. At the moment when energy is increasingly in short supply, hydropower generation is particularly important. The tail water is wasted in vain, and the utilization of tail water is paid more and more attention by people. Most of the existing tail water power generation devices are simple in structure, the utilization rate of tail water is not high, and the operation is not stable enough, as published in Chinese patent CN 201013525Y A tail water power generation device of a hydropower station, although it can utilize the tail water, but the design structure is simple, and the utilization rate of the tail water is not high

In some hydropower stations, the width of the river channel in the tailwater stage is not fixed, or the area with a small drop below it is not suitable for large-scale hydropower generation. However, the current tailwater generators are all fixed and not flexible enough to use
