Detailed Description

In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

Example one

As shown in fig. 1-2, a pipeline energy storage hydroelectric power station comprises a pipeline group, a dam 6 and a generator set 5, wherein the pipeline group comprises 4 low-

pressure pipes

1, 2 medium-

pressure pipes

2 and 1 high-pressure pipe 3, each 2 low-pressure pipes 1 are connected with the medium-pressure pipes 2 in a two-to-one mode, 2 medium-pressure pipes 2 are connected with the high-pressure pipes 3 in a two-to-one mode, the low-pressure pipes 1 are connected with the dam 6 and are positioned on the upper side with large river fall, and the high-pressure pipes 3 are connected with the generator set 5 and are positioned on the lower side with large river fall. Two water outlets 4, one large and one small, are arranged below the high-pressure pipe 3, the water outlets 4 are provided with gates, and the water outlets 4 respectively correspond to the generator sets 5 with corresponding power. One end of the retaining dam 6 is provided with a navigation flood discharge gate 8. The water blocking dam 6 is provided with a protective net 9 and a pipeline gate 7 corresponding to the low-pressure pipe 1.

When the device is used, the pipeline gate 7 is opened, a river flows into the 4 low-pressure pipes 1, the generator sets with different powers are selected according to the flow of the river through the 2 medium-pressure pipes 2 and the 1 high-pressure pipe 3, the gate of the water outlet 4 is opened, the river drives the generator set 5, the generator sets with different powers are selected when the flow is small, the generator set with large flow is selected when the flow is medium, and the generator sets with large flow and small flow run together when the flow is large. Optionally, the pipe set may be protected by a layer of reinforced concrete 12 to provide flood relief when the river flow is too high.
