The support block 31 is located at the lower side of the water turbine 100 and is used to support the water turbine 100. The support surface of the support block 31 has an arc that matches the water turbine 100, so that the support block 31 can fit the water turbine 100. The clamp bar 32 is clamped on the water turbine 100 and one end is fixed on the base 1, and the other end is inserted into the plug hole 21.

[0053] The pipe connection part is installed on the base 1 , and the water inlet pipe 101 of the water turbine 100 is connected with the water supply pipe 5 through the pipe connection part.

[0054] The limiting device for the pumped-storage turbine unit of the present embodiment provides support and limiting for the turbine by arranging a plurality of limiting parts around the turbine, connects the water supply pipe and the water inlet pipe of the turbine through the pipe connecting part, and the pipe connecting part and the plurality of limiting parts are all installed on the same base to form a whole, thereby preventing the turbine from moving or deflecting during use, improving the stability of the equipment and reducing the failure rate.

[0055] In one example, see Figure 1 and Figure 2 As shown, the clamp strip 32 includes a C-shaped segment 321 and a Z-shaped segment 322, wherein one end of the Z-shaped segment 322 is connected to the base 1 by means of fasteners such as screws or bolts, and the other end is welded to the C-shaped segment 321. The clamping surface of the C-shaped segment 321 is attached to the turbine 100, and one end is inserted into the plug hole 21 to form a stable clamping limit. In addition, the segmented structure makes processing more convenient.

[0056] In this embodiment, preferably, the cross section of the support block 31 is I-shaped.

[0057] In this embodiment, preferably, the pipe connecting portion is a hollow box body 4, and the opposite sides are respectively connected to the water inlet pipe 101 and the water supply pipe 5 of the turbine, so as to realize the connection between the water inlet pipe 101 and the water supply pipe 5 of the turbine, and at the same time realize further limiting of the turbine 100.

[0058] In order to seal the water delivery pipe 5 when not in use, in one example, a detachable sealing cap 51 is provided at the end of the water delivery pipe 5. Preferably, the sealing cap 51 is threadedly connected to the water delivery pipe 5.

[0060] In order to achieve the limit and adjust the water flow at the same time, in one example, see Figure 1 and Figure 4 As shown, an inverted U-shaped hanging frame 42 is provided on the hollow box body 4, and the inverted U-shaped hanging frame 42 is located above the hollow box body 4. Multiple adjustment plates 43 are arranged in parallel, and one end of each of the adjustment plates 43 passes through the upper cover plate 41 and is inserted into the hollow box body 4, and the other end of each adjustment plate 43 is connected to the inverted U-shaped hanging frame 42 through a telescopic rod 44. Each adjustment plate 43 is provided with an adjustment hole 431, and the diameters of the adjustment holes 431 on each adjustment plate 43 are different, that is, the water flow rate that can pass through is different. According to needs, the required adjustment plate 43 can be selected to pass water by telescoping the telescopic rod 44, so as to control the water volume and thus adjust the speed of the turbine. Preferably, a sealing ring is provided between the adjustment plate 43 and the upper cover plate 41 to improve the sealing performance.
