Embodiment 1
[0041] see Figure 1-9 , an inflatable hydropower station ecological tailgate, which includes an upper door leaf 1 and a lower door leaf 2, the upper door leaf 1 and the lower door leaf 2 are made of rubber door panels 24; the upper and lower top ends of the rubber door panels 24 Both are provided with a supporting steel sheet 23, and the two ends of the supporting steel sheet 23 respectively form a sliding fit with the left gate groove 17 and the right gate groove 18; the upper door leaf 1 and the lower door leaf 2 are arranged symmetrically on the Both sides of the upper door leaf 1 and the upper end of the lower door leaf 2 are connected with the double-layer casing 3; the two ends of the double-layer casing 3 are fixedly installed in the middle of the entire gate, which includes an outer tube 8 and Inner pipe 9; the outer pipe 8 is set on the outside of the inner pipe 9; the left side of the inner pipe 9 is provided with an air inlet 15, and the right side is provided with...
Embodiment 2
[0055] Utilize the equipment and structural dimensions used in the ecological tailgate of a kind of inflatable hydropower station of the present invention:
[0056] 1. The total length of the door leaf is 6m, the arc diameter at both ends is 0.5m, the width is 0.3m, and the height is 3m;
[0057] 2. Two air pressure sensors inside each door leaf are located at the bottom of the rubber door panel at 1.5m and 4.5m along the length direction;
[0058] 3. The length of the outer pipe is 6.4m, the outer diameter is 0.15m, the inner diameter is 0.145m, the length of the outer pipe ventilation groove is 4m, the width is 0.075m, the radius of the downstream exhaust hole is 0.05m, and the pipe section corresponding to the outer pipe ventilation groove is from 1.6m to 4.8m A downstream exhaust hole with a diameter of 0.05m is provided at every 0.8m of the pipe section;
[0059] 4. The length of the inner pipe is 8m, the outer diameter is 0.14m, the inner diameter is 0.135m, the length ...
Embodiment 3
[0064] Utilize a kind of inflatable hydropower station ecological tailgate of the present invention, can carry out according to the following steps:
[0065] When the gate is in the closed state and the gate needs to be opened, the motor 19 is started, and the driving sprocket 20 drives the driven sprocket 22 through the transmission chain 21, so that the inner pipe 9 starts to rotate counterclockwise. When the upper inner pipe ventilation groove 12 of the inner pipe 9 Align with the upper outer tube ventilation slot 10 of the outer tube 8, when the lower inner tube ventilation slot 13 of the inner tube 9 is aligned with the lower outer tube ventilation slot 11 of the outer tube 8, turn off the motor 19, and the downstream exhaust hole 14 of the outer tube 8 will be in a closed state, close the air outlet 16 of the inner pipe 9, and inflate the air inlet 15 through the main gas supply pipe of the hydropower station, and the gas enters the interior of the upper door leaf 1 and t...
