Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The present invention is suitable for siphon type direct-drive tubular water turbine with low water head or ultra-low water head, and its structure is as follows: figure 1 As shown, including a siphon 1, a direct-drive generator set 5 is installed in the siphon 1, and a stator 7 of the direct-drive generator 5 is fixedly installed on the inner wall of the siphon 1, as Figure 2-4 As shown, the runner 8 of the direct drive generator set 5 is connected with the stator 7 through a bearing.

[0025] The siphon pipe 1 includes a water inlet section 1-1, an ascending section 1-2, a hump section 1-3, a horizontal section 1-4 and a descending section 1-5, which are sequentially connected as one. The direct drive generator set 5 is installed on the horizontal section 1 -4.

[0026] The front and rear ends of the direct drive generator set 5 a...

Abstract

The invention discloses a siphon type direct-driven through-flow turbine suitable for a low water head or an ultra-low water head. The siphon type direct-driven through-flow turbine comprises a siphonpipe, wherein a direct-driven generator set is mounted in the siphon pipe; a stator of the direct-driven generator set is fixedly mounted on the inner wall of the siphon pipe; and a rotating wheel ofthe direct-driven generator set is connected with the stator through a bearing. The siphon type direct-driven through-flow turbine suitable for the low water head or the ultra-low water head solves the problem of loose sealing between dynamic and static parts caused by the fact that a main shaft of a siphon type water turbine penetrates through the siphon pipe in the prior art.

Description

technical field [0001] The invention belongs to the technical field of water turbines, and relates to a siphon type direct-drive tubular water turbine suitable for low water head or ultra-low water head. Background technique [0002] my country's coastal areas are rich in hydropower resources. However, with the gradual development of high-head hydropower resources and the increase in demand for electricity in coastal areas, the development demand for low-head hydropower resources continues to rise. Compared with high-head power stations, under the condition of the same output, low-head power stations will increase the unit size, civil engineering workload and unit investment cost. Most of the traditional low-head hydropower stations use tubular turbines to operate under low or ultra-low head, and there are many problems such as low operating efficiency, serious unit cavitation, and short operating period. The siphon turbine has the advantages of convenient installation and ...
