Description

Technical Field

[0001] This utility model relates to a semi-underground vertical shaft powerhouse for a pumped storage power station, belonging to the technical field of power station facility structure. Background Technology

[0002] A pumped storage power station requires a height difference between its upper and lower reservoirs to ensure that the water in the upper reservoir can flow by gravity to the lower reservoir for power generation. Therefore, pumped storage power stations are typically built in mountainous environments.

[0003] Existing pumped storage power stations are constructed in mountainous environments, as shown in Chinese Patent Publication No. CN117684524A. The entire workshop space for installing the turbines is underground, and the limited underground construction space makes it inconvenient to stack or adjust turbine components. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a semi-underground vertical shaft powerhouse for pumped storage power stations.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a semi-underground vertical shaft powerhouse for a pumped storage power station, comprising:

[0007] The mountain has an open horizontal surface excavated on its side, and a vertical shaft is excavated below the open horizontal surface.

[0008] The shaft contains an underground powerhouse section, the top of which extends out to an open horizontal plane. Water turbines and generators are installed inside the underground powerhouse section.

[0009] The underground factory building has an open horizontal section at the top covered by a cover.

[0010] The underground plant section located at the top of the shaft has crane legs inside its top, on which cranes are mounted.

[0011] The above-ground factory building is constructed on the open horizontal surface away from the side of the mountain.

[0012] A transformer station is constructed on the open horizontal surface away from the side of the above-ground factory building.

[0013] The beneficial effects of this utility model are as follows: When installing the water turbine and generator, they can be hoisted and placed through the top of the underground powerhouse. The top of the underground powerhouse is an open horizontal plane, which facilitates the stacking or adjustment of the components of the water turbine and generator, and solves the problem that the limited underground construction space makes it inconvenient to stack or adjust the components of the water turbine.

[0016] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0017] like Figure 1 As shown.

[0018] This application discloses a semi-underground vertical shaft powerhouse for a pumped storage power station, comprising:

[0019] The mountain body 1 has an open horizontal plane 2 excavated on its side. A vertical shaft 3 is excavated beneath the open horizontal plane 2. An underground powerhouse section 4 is located within the shaft 3, housing a water turbine 5 and a generator 6. Water is introduced into the water turbine 5 through its inlet 51 to drive its rotation, and the water turbine 5 drives the generator 6 to generate electricity. The top of the underground powerhouse section 4 protrudes upwards from the open horizontal plane 2 and is covered by a cover 81. The cover 81 provides protection when the water turbine 5 and generator 6 are operating; it is opened and removed during maintenance or installation.

[0020] The underground plant section 4, located at the top of the shaft 3, has a crane leg 7 inside its top, on which a crane 8 is installed. The above-ground plant section 9 is constructed on the open horizontal plane 2 away from the mountain 1, and is used to house control boxes and other related equipment.

[0021] A transformer station 10 is constructed on the open horizontal plane 2 on the side away from the above-ground factory building 9. The transformer station 10 transforms the power supply.

[0022] In this application, the turbine 5 and generator 6 can be hoisted into place through the top of the underground powerhouse section 4. The top of the underground powerhouse section 4 is located on an open horizontal plane 2, which facilitates the stacking or adjustment of the turbine 5 and generator 6 components, solving the problem that the limited underground construction space makes it inconvenient to stack or adjust turbine components. The crane 8 can provide hoisting operations for adjusting the components of the turbine 5 and generator 6.
