Air floatation type dam gate
The invention discloses an air floatation type dam gate. The air floatation type dam gate is characterized by comprising an upper fixed pulley and a lower fixed pulley; one end of a first mooring rope is connected with the top edge of the gate, and the other end of the first mooring rope winds across the upper fixed pulley to be connected to a pulley support of a movable pulley; one end of a second mooring rope is fixed to the bottom of a dam body, and the other end of the second mooring rope sequentially winds across the movable pulley and the lower fixed pulley to be connected with a gate starting airbag; one end of a mooring rope on the left side and one end of a mooring rope on the right are connected to the corresponding sides of the gate respectively, and the other ends wind across the fixed pulleys to be connected with a gate closing airbag; the air floatation type dam gate is provided with a flood discharge magnetic float position switch, a water storage magnetic float position switch, an electromagnetic switch and an air pump; the water level is detected through the switches, then air inflation and deflation control is achieved over the gate starting airbag and the gate closing airbag, and then starting and closing control over the gate is achieved. The air floatation type dam gate is suitable for the areas with inconvenient traffics and low power supply assurance rate, the management difficulty is reduced, dam safety is ensured, and water resource waste is avoided.
