Rope type rotating weir and control method of rope type rotating weir
The invention discloses a rope type rotating weir and a control method thereof, and the rope type rotating weir comprises a weir plate which is rotatably arranged in a water passing channel and divides the water passing channel into an upstream and a downstream; a fixed pulley; a deflecting pulley; one end of the traction rope is connected with the weir plate, and the other end sequentially bypasses the fixed pulley and the steering pulley to be connected with the driving device; and the driving device is used for winding and unwinding the traction rope, so that the traction rope can drive the weir plate to rotate. In the process of increasing the opening degree of the weir plate, the gravity of the weir plate is beneficial to continuous increase of the opening degree. And in the process of reducing the opening of the weir plate, the opening can be continuously reduced under the action of water pressure. Therefore, based on the rope type rotating weir, the opening degree of the weir plate can be controlled by controlling the winding and unwinding amount of the traction rope, and the precision reliability and controllability are better. And no matter the opening degree is increased or decreased, the pressure or water pressure of the weir plate is beneficial to rotation of the weir plate, and the driving device is more labor-saving, so that the advantage of low energy consumption is achieved.
本发明公开一种绳式旋转堰及其控制方法，包括：堰板，用于可旋转式的设置于过水通道，将过水通道分割为上游和下游；定滑轮；转向滑轮；牵引绳，一端连接堰板，另一端依次绕过定滑轮、转向滑轮与驱动装置连接；驱动装置，用于收放牵引绳，以使得牵引绳可带动堰板做旋转运动。在堰板开度增大的过程中，堰板的自身重力有利于开度的继续增大。在堰板开度减小的过程中，水压的作用有利于开度的继续减小。因此，基于绳式旋转堰，控制牵引绳的收放量即能控制堰板的开度，精度的可靠性和可控性更好。而且不管是开度增大还是开度减小的过程，堰板自身的压力或者水压都有利于堰板的旋转，驱动装置更加省力，从而到有低能耗的优点。
