Rubber ball number on-line monitoring and automatic ball supply device and method based on ultrasonic sensing technology

The invention belongs to the technical field of thermal power generation cold end optimization and discloses a rubber ball number on-line monitoring and automatic ball supply device and method based on an ultrasonic sensing technology. The ball supply device comprises an ultrasonic sensor, a data acquiring, analyzing and processing unit, a ball loading chamber, a standby rubber ball chamber and arubber ball pump. The rubber ball pump is connected with the ball loading chamber through a rubber ball pump outlet electric ball valve. The rubber ball pump is connected with the standby rubber ballchamber through a standby rubber ball chamber inlet electric ball valve. The standby rubber ball chamber is connected with the ball loading chamber through a standby rubber ball chamber outlet electric ball valve. The ball supply device is simple and practical, and the effect that sufficient rubber balls exist in a system to be effectively cleaned is ensured; and the device can achieve central control room on-line monitori
