be separately fixed atpower transmission shaft 3
two ends,second gear 23 utilizes power transmission shaft 3 to be formed with the second runner 22 and is coaxially fixedly connected with relation
,power transmission shaft 3 two ends are enclosed within two circular axle bed 31 peripheries, left and right rotationally, can freely rotate around circular axle bed 31, namely around the second gear 23 center axis thereof.First runner 12 is positioned at directly over the second runner 22, intermediate roller 4 is between the first runner 12 and the second runner 22, the rotating shaft 41 of intermediate roller 4 is fixedly mounted on the movable end of activity swing arm 5, intermediate roller 4 can around its rotating shaft 41 rotation, and the movable end of activity swing arm 5 can swing up and down around the balance staff 51 of activity swing arm; First runner 12 is fixed on the end of the first levels operation axle 11 and rotates in company with the first levels operation axle 11.
Shown in Fig. 6, Fig. 7, Fig. 8, first runner 12 periphery is formed with the first arc notch 14, second runner 22 periphery is formed with the second arc notch 24, contour shape, the size of the second runner 22 are identical with the contour shape of the first runner 12, and shape, the size of the first arc notch 14 are identical with the second arc notch 24; The arc radius of the first arc notch 14 is equivalent to 1.05 times of intermediate roller radius, the arc radius of the first arc notch 14 i.e. the arc radius of Fig. 7 mean camber line CAD;
Shown in Fig. 5, Fig. 9, form following geometrical relationship between the notch depth n of the wheelbase m between the first runner and the second runner, the first runner radius R, intermediate roller radius r, the first arc notch: m=2R+2r-n; First runner radius R is equivalent to 2.5 times of intermediate roller radius r;

The course of work and the principle of above-described embodiment are as follows:
One, in an initial condition, first levels operation axle 11 turns to open position, second levels operation axle 21 also can be turned to open position simultaneously, now, first arc notch 14 of the first runner 12 aims at intermediate roller 4, second arc notch 24 of the second runner 22 also aims at intermediate roller 4, as shown in Figure 5, Figure 9;
Two, if want to change Fig. 5, initial condition shown in Fig. 9, the first on-load switch 1 is such as want to close a floodgate, then the first levels operation axle 11 can be rotated counterclockwise 90 °, so the first on-load switch 1 closes a floodgate, first arc notch 14 of the first runner 12 turns to the position of departing from intermediate roller 4 simultaneously, the profile of the first runner 12 pushes down intermediate roller 4 downwards, intermediate roller 4 is made closely to embed the second arc notch 24 of the second runner 22 downwards, second runner 22 is locked, so the second runner 22 and power transmission shaft 3, second gear 23, first gear 13, second levels operation axle 21 can not rotate, namely the second levels operation axle 21 is locked in open position, second on-load switch 2 can not be closed a floodgate, as shown in Figure 10,
Three, if want to change the state shown in Figure 10, that is, if want the 2-in-1 lock of the second on-load switch under the state shown in Figure 10, again the first levels operation axle 11 can only be rotated backward 90 ° (rotating clockwise 90 °), reach two on-load switches 1, 2 initial conditions being all in separating brake, as Fig. 5, shown in Fig. 9, then the second levels operation axle 21 is rotated clockwise 90 °, so the 2-in-1 lock of the second on-load switch, second levels operation axle 21 drives the first gear 13 simultaneously, second gear 23, power transmission shaft 3, second runner 22 rotates 90 °, so intermediate roller 4 is pushed out the second arc notch 24, activity swing arm 5 upwards rotates clockwise around activity swing arm rotating shaft 51, intermediate roller 4 is closely embedded the first arc notch 14 entering the first runner 12, and the second arc notch 24 of the second runner 22 turns to the position of departing from intermediate roller 4, the profile of the second runner 22 upwards press against intermediate roller 4, as shown in figure 11, so the first runner 12 and the first levels operation axle 11 can not rotate, namely the first levels operation axle 11 can not forward closing position to, first on-load switch 1 can not close a floodgate, as shown in figure 11,
Four, same, if want to change the state shown in Figure 11, that is, if want under the state shown in Figure 11, the first on-load switch 1 to be closed a floodgate, again the second levels operation axle 21 can only be rotated backward 90 ° (rotating counterclockwise 90 °), reach the initial condition coming back to " two on-load switches are all in separating brake " shown in Fig. 5, just can carry out the operation of " being closed a floodgate by the first on-load switch 1 ".
