Description

Technical Field

[0001] This utility model relates to the field of dam slope reinforcement, and more specifically, to a dam slope reinforcement device for pumped storage power stations. Background Technology

[0002] Pumped storage power stations utilize electricity generated during periods of low electricity load to pump water to an upper reservoir and release it to a lower reservoir during periods of high electricity load to generate electricity. They can convert excess electricity generated during periods of low grid load into high-value electricity generated during periods of high grid load. They are also suitable for frequency and phase regulation, stabilizing the frequency and voltage of the power system, and are ideal for emergency backup. Furthermore, they can improve the efficiency of thermal power plants and nuclear power plants in the system.

[0003] However, the current pumped storage power station dam slopes are prone to poor stability during long-term use, making them susceptible to landslides. This is compounded by the fact that most fastening plates are square, resulting in low stability, small stress area, and short service life. Furthermore, when a landslide occurs, the soil layer cannot be effectively buffered to reduce the affected area and damage.

[0004] Therefore, a pumped storage power station dam slope reinforcement device is provided to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the following issues: the dam slopes of pumped storage power stations are prone to poor stability and landslides during long-term use; the square shape of most fastening plates results in low stability and strength, small stress area, and short service life; and the inability to effectively buffer the soil layer to reduce the affected area and damage when a landslide occurs.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A pumped storage power station dam slope reinforcement device includes a slope plate. An anchor is fixedly connected to one side of the slope plate. A snap-fit ​​groove is formed on both sides of the upper surface of the slope plate. A snap-fit ​​component adapted to the snap-fit ​​groove is formed on both sides of the lower surface of the slope plate. Adjusting components are fixedly connected to both sides of the bottom of one side of the slope plate. A connecting component is movably snapped into the adjusting component. An adjusting bolt is threadedly connected to the snap-fit ​​joint between the connecting component and the adjusting component. A sleeve is fixedly connected to one end of the connecting component, and one end of the sleeve has an internal thread groove.

[0008] As a preferred technical solution of this application, the sleeve is threadedly connected to an extension rod through an internal thread groove, and a connecting groove is opened at one end of the extension rod, through which a conduit is slidably connected.

[0009] As a preferred technical solution of this application, one end of the conduit is provided with a torsion spring, and an extension member is movably connected through the torsion spring. An injection hole is provided at the top of the inner arc surface of the conduit and at the top of the inner arc surface of the connecting groove.

[0010] As a preferred technical solution of this application, a reset spring is fixedly connected to the inner wall of the connecting groove, and one end of the reset spring is fixedly connected to one end of the conduit.

[0011] As a preferred technical solution of this application, one end of the extension rod is connected to a pull rod, one end of the pull rod is fixedly connected to one end of the conduit, and the reset spring is sleeved on the pull rod.

[0012] As a preferred technical solution of this application, a positioning ring is fixedly connected to one end of the pull rod, the diameter of the positioning ring being adapted to the internal thread groove of the sleeve, and a movable groove adapted to the positioning ring is provided at one end of the extension rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this application, the design incorporates a tie rod, positioning ring, return spring, injection hole, extension piece, and conduit, allowing workers to more easily install the slope plate on the slope. Simultaneously, the extension plate's pop-out unfolds, fixing the extension rod inside the slope. Concrete slurry is then injected into the extension rod, conduit, and slope through the injection port, thus securing the slope plate and effectively preventing damage to the slope's soil layer. This addresses the problems of existing pumped-storage power station dam slopes, which are prone to landslides due to poor stability over long-term use; the limitations of most fastening plates being square, resulting in low stability, small bearing area, and short service life; and the inability to effectively buffer the soil layer to reduce the affected area and damage when a landslide occurs.
