Vortex eliminating device for hydropower station water inlet and vortex eliminating adjusting method
The invention provides a vortex eliminating device for a hydropower station water inlet and a vortex eliminating adjusting method. The vortex eliminating device comprises fixed arms, a guide rail, a connecting rod mechanism and vortex eliminating wings. The vortex eliminating device is arranged between two connecting beams of a first layer and a second layer of the hydropower station water inlet.The fixed arms are fixedly connected with a hydropower station foundation, the connecting rod mechanism rotates around the guide rail, and the vortex eliminating wings rotate around the connecting rodmechanism. The two vortex eliminating wings located on the same guide rail are opposite in rotating direction, on the premise that layered water taking and discharged water temperature increasing arenot affected, a composite vortex structure near the hydropower station water inlet is effectively eliminated, water flow turbulence of a water inlet pipe is reduced, and safe operation of a generatorset is guaranteed. The working time and the working intensity of the vortex eliminating device are optimized, and the head loss of a hydropower station is reduced.
一种水电站进水口的消涡装置及消涡调节方法，它包括固定臂、导轨、连杆机构和消涡旋翼，通过在水电站进水口的第一层和第二层的两根联系梁之间设置该装置，通过固定臂与水电站基础连接固定，通过连杆机构绕导轨旋转，通过消涡旋翼绕连杆机构，位于同一根导轨上的两个消涡旋翼的旋转方向相反，在不影响分层取水、提高下泄水温的前提下，有效消除水电站进水口附近复合涡旋结构，降低进水管水流紊动，保证发电机组的安全运行，有利于优化消涡装置的工作时间和工作强度，降低水电站的水头损失。
