Embodiment
[0033] The novel tailrace tunnel ventilation orifice structure of this embodiment, such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, when the movable baffle 2 is closed, the air flow can only pass through the reserved round hole 9 in the movable baffle 2, the movable connecting rod 3 is fixed with the movable baffle 2, and the annular anti-slip block body 6 is used to fix the movable connecting rod 3. direction. A movable baffle 2 is set at the ventilation hole 1. When the movable baffle 2 is opened, the movable connecting rod 3 slips sideways. A lubricating device 10 is arranged between the annular anti-slip block body 6 and the movable connecting rod 3. The spring buffer device 5 is used to protect The movable connecting rod 3, when the movable baffle 2 is pushed up by the air flow of the intake air, the movable connecting rod 3 moves accordingly, compressing the spring 4, at this time, the ventilation hole is full-area air intake; when the mova...
