Embodiment Construction
[0008] The invention will be further explained below in conjunction with the drawings.
[0009] Such as Figure 1-2 As shown, the energy-consuming opening and closing device and gate opening and closing method of the arc gate disclosed in the present invention consist of a water distribution tank 1, a connecting water pipe 2, a connecting water pipe valve 3, an exhaust hole 4, a water distribution box bracket 5, a drain pipe 6, and a drain The water distribution box 1 and the water distribution box bracket 5 are fixedly arranged together and fixedly arranged on the arm of the arc gate. One end of the connecting water pipe 2 is connected with the water distribution tank 1 and the other end is fixedly arranged at the lower part of the arc gate. The opening on the arc gate is connected to the connecting water pipe 2, and the drain pipe (6) is fixedly arranged at the lower part of the water distribution tank (1). When the gate is closed, the gate end of the connecting water pipe 2 is...

The invention discloses an energy-consumption-free arc gate opening / closing device and a gate opening / closing method. The arc gate opening / closing device comprises a water distribution tank, a communication water pipe, a communication water pipe valve, a gas discharge hole, a water distribution tank support, a water discharge pipe, and a water discharge pipe valve. According to the energy-consumption-free arc gate opening / closing device, a water tank is arranged in the reverse direction of the gate, after the water tank is full of water, the moment of the self gravity to a hinge shaft is large than the moment of an arc gate to the hinge shaft, when the gate needs to be opened, a water inlet valve is opened, water in a reservoir enters the water tank through the water pipe by virtue of self gravity, and the gate is automatically opened slowly when the moment of the self gravity of the water tank and the gravity of the water in the water tank to the center of the hinge shaft is large than the moment of the arc gate to the hinge shaft; when the gate needs to be closed, water in the water tank is discharged, and the gate is automatically closed slowly when the moment of the self gravity of the water tank and the gravity of the water in the water tank to the center of the hinge shaft is smaller than the moment of the arc gate to the hinge shaft; the energy supply is not needed for opening / closing the gate.
Description
Technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a non-energy-consuming opening and closing device for an arc gate and a gate opening and closing method. Background technique [0002] When the arc gate is opened and closed, the gate rotates around a fixed hinged horizontal axis. The center of the hinge shaft is generally arranged at the center of the arc-shaped panel, so all the water pressure acting on the panel passes through the centroid. When opening and closing the gate, it is only necessary to overcome the resistance moment of the gate's own weight and the frictional resistance of the water stop on the shaft center. Therefore, the arc gate has the advantages of labor-saving opening and closing and good hydraulic conditions. It is one of the priority gate types in the selection of hydraulic structures. Although the arc gate has the advantage of the minimum required opening and closing force, the opening a...
