Embodiment 1
[0031] Such as Figure 1~2 As shown, an embedded part structure includes a main body section 2 with a rectangular cross section, a gate groove 5 arranged on the main body section 2 , and a pressure slope section 4 .
[0032] The structure of the slope section 4 includes a horizontal bottom surface 41 , two wall surfaces 42 perpendicular to the bottom surface 41 , and a top surface 43 . The bottom surface 41 , the side wall surface 42 and the top surface 43 are enclosed to form a hollow structure with closed sides and open ends. The top surface 43 is a slope surface that gradually slopes downward from the upstream to the downstream direction, so that the pressure slope section 4 forms a variable cross-sectional structure with a diameter that gradually decreases. The slope ratio of the top surface 43 is 1:10.
[0033] The upstream end of the slope section 4 is butted against the downstream end of the main body section 2 .
[0034] This embodiment also provides a gate system, ...
Embodiment 2
[0040] Such as image 3 As shown, repeat embodiment 1, the difference is that the construction location of embodiment 1 is outside the tunnel, the construction location of embodiment 2 is located in the tunnel, and the water head at the working gate 31 of embodiment 2 is 130.0m.
[0041] The circle-to-square transition section 1 , the gate mechanism 3 , and the embedded structure are all located in the tunnel 7 . In the tunnel 7, near the downstream end of the pressure slope section 4, there is a ventilation hole 6 communicating with the outside world. The junction between the downstream end of slope pressure section 4 and the tunnel adopts a sudden expansion design scheme.
[0042] The purpose of designing the vent hole 6 is to supply air to the outlet of the downstream end of the slope section 4, so as to balance the pressure change of the water flow from pressurized to non-pressurized.
