Abstract
The utility model relates to a hydraulic flap gate, two ends of a connecting rod of the gate are respectively connected with two pivoted shafts, wherein one pivoted shaft is arranged on a support leg, the other pivoted shaft is arranged on a buttress, an idler wheel is arranged on the buttress, the support leg leans against the idler wheel, a door plate is attached on the support leg, and the door plate and the support leg are obliquely arranged on a dam body. With the adoption of the utility model, when the gate is opened, the whole center of gravity can be quickly deviated from the position of the original center of gravity, therefore, the gate can be opened quickly, and the sensitivity performance can improved; simultaneously, the sway phenomenon can not be generated, and the service life of the gate is prolonged.
Description
Technical field
The utility model relates to a kind of waterpower flap gate.
Background technology
In hydraulic facilities, need to use a kind of flap gate that can open automatically usually, break and when not having flood forecasting in case rise suddenly and sharply at water level, the superiority of this gate just can embody, this gate is controlled by waterpower, and it is made up of door-plate, supporting leg, buttress, roller, connecting rod, twisted axis, and connecting rod is located on the roller, the two ends of connecting rod are connected with two twisted axis respectively, roller is positioned on the buttress, and supporting leg leans against on the roller, and door-plate is perpendicular to dam body and be attached on the supporting leg.Whole center of gravity during this gate opening is only moving with the center of gravity direction with door-plate basically, the moment of closing the door reduces amplitude and reduces amplitude less than the moment of opening the door, close the door moment greater than the moment of opening the door, thereby cause gate in certain unlatching or the certain hour of closing, to open and close repeatedly, the continuous shaking phenomenon of gate appears, both influence the performance of gate, influenced the application life of gate again.
Summary of the invention
The purpose of this utility model provides a kind of waterpower flap gate of the unlatching sensitivity that can improve gate.
The technical scheme that the utility model is taked is: a kind of waterpower flap gate, comprise door-plate, supporting leg, buttress, roller, connecting rod and twisted axis, the two ends of connecting rod are connected with two twisted axis respectively, a twisted axis is located on the supporting leg, another twisted axis is located on the buttress, and roller is positioned on the buttress, and supporting leg leans against on the roller, door-plate is attached on the supporting leg, it is characterized in that door-plate and supporting leg are obliquely installed on dam body.
Adopt the utility model, whole center of gravity can depart from original position of centre of gravity very soon during gate opening, thereby causes gate to open rapidly, has improved sensitive performance, simultaneously, shaking phenomenon can not occur, has prolonged the application life of gate.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Sequence number is represented among the figure: door-plate 1, supporting leg 2, connecting rod 3, twisted axis 4, buttress 5, dam body 6 and roller 7.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
With reference to Fig. 1, this gate comprises door-plate 1, supporting leg 2, buttress 5, roller 7, connecting rod 3 and twisted axis 4, the two ends of connecting rod 3 are connected with two twisted axis 4 respectively, a twisted axis 4 is located on the supporting leg 2, and another twisted axis 4 is located on the buttress 5, and the two ends of connecting rod 3 are connected with twisted axis 4, roller 7 is positioned on the buttress 5, supporting leg 2 leans against on the roller 7, and door-plate 1 is attached on the supporting leg 2, and door-plate 1 and supporting leg 2 are obliquely installed on dam body 6.
During use, when upper pond level raises, surpass and open a water level, flowing pressure to support moment greater than the Men Chongyu frictional resistance during to support moment, because of door-plate 1 and supporting leg 2 are obliquely installed on dam body 6, the deviation of gravity center of door-plate 1 and supporting leg 2 is very fast, therefore can turn over to the right all the time, pulling twisted axis 4, the bottom of drivening rod 3 upwarps, and makes gate opening angled, when flowing pressure equals the Men Chongyu frictional resistance to support moment to support moment, reach new balance, door-plate 1 and supporting leg 2 just keep motionless, and the gate opening angle also just remains unchanged.When upper pond level descends, door heavily to support moment greater than flowing pressure and frictional resistance during to support moment, equally, because of door-plate 1 and supporting leg 2 are obliquely installed on dam body 6, the center of gravity of door-plate 1 and supporting leg 2 also departs from very fast, therefore can turn over left all the time, pulling twisted axis 4, the upper end of drivening rod 3 upwarps, and makes gate begin to close and closes, up to reaching new balance.Like this, just can not produce keying repeatedly, the continuous shaking phenomenon of gate can not occur.
