A water turbine guide system with remote control function

Abstract

The invention relates to a water turbine water guiding system with a remote control function. The water turbine water guiding system with the remote control function comprises a center mechanism, a bottom ring, a plurality of transmission mechanisms which are evenly distributed on the outer side of the center mechanism in the circumferential direction, and a plurality of steering mechanisms which are evenly distributed on the inner side of the bottom ring in the circumferential direction. The number of the transmission mechanisms is equal to the number of the steering mechanisms, and the transmission mechanisms are in one-to-one correspondence with the steering mechanisms. According to the water turbine water guiding system with the remote control function, guide vanes are driven to rotate through the center mechanism; since the transmission mechanisms are used by the guide vanes independently, the number of gaps of mechanical connection is reduced, and the driving requirement is lowered; the acting forces of the steering mechanisms on the guide vanes are the same, so that the steering directions of the guide vanes are consistent, operation is more stable while uniform stress is guaranteed; and furthermore, an electric oscillation signal is converted into an ultrasonic signal through a frequency oscillator, composed of an ultrasonic sensor, a first triode and a second triode, in an ultrasonic transmitting circuit, and conventional elements are adopted, so that the production cost is reduced, and the practical value of the system is improved.

Description

technical field [0001] The invention relates to a hydraulic turbine water guide system with remote control function. Background technique [0002] In the hydropower generation system, according to the usage of the power system load, it is necessary to adjust the generating power of the hydraulic turbine in real time to meet the requirements of the system for the unit. In order to achieve the purpose of adjusting the generating The direction of the leaves controls the flow rate of the water flow, and in turn adjusts the amount of work done by the water flow on the water turbine, thereby realizing the change of the power generation of the water turbine. [0003] In the existing hydraulic turbine water guide system, usually two servomotors operate the rotation of the control ring to drive the rotation of the guide vane angle. During the operation, the servomotor has few action points on the control ring, so the servomotor is required. Only a large driving force can push the co...
