In steady state the operation of the hydraulic level control is provided by the interaction of contrast and float through the swinging crossbar. When this float is associated with the membrane mechanism controller through the cable. This functional separation of the components of the device significantly complicates the design, reduces the accuracy and stability of the job setting.The closest in technical essence of the present invention is a device for changing the setpoint level regulators with hydraulic sensor /2/ containing shaper electrical signals, a float and a mechanism for changing the position of the float including the motor and gearbox. The float is in the position of the float. When the setpoint changes, the float moves along the rod, made in the form of a lead screw kinematically connected with the electric motor.The disadvantage of this device is the increased power of the motor required to enforce a full immersion of the float in the water when the setpoint changes. This limits the application of this device in telecontrol systems management. The application of the lead screw to move the float in contact with mineralized water and exposed to pollution, significantly reduces the reliability and stability of the device.The objective of the invention is to simplify the design and reduce power consumption of the device.The solution is achieved by the fact that in the proposed device, the float is made in the form of a toroidal body, in the middle part of which is the shaper of electrical pulses, motor, gearbox and drum for winding a running rope connected to the control valve to the hydraulic level control.To reduce the power consumption command to change the setpoint of the controller is performed in a pulsed mode. The pulse duration of the inclusion of the motor is determined by the same process, water level control, then the process of changing the setpoint is resumed, and so on until it ends.The drawing shows a diagram of the device for remote changing of setting of hydraulic level control.The device consists of a float 1 in the form of a toroidal body, in the middle part of which is mounted the driver of electrical pulses 2 and the mechanism for changing the position of the float including the electric motor 3 and a gear 4 which additionally included the drum 5 for winding a running rope 6, kinematically associated with the control valve of the hydraulic control water level 7.The device operates as follows.The float 1 is the flow in the working position. Its orientation in space is limited to running cable 6 connected with the valve 7 controls the hydraulic control of the water level. When submitting commands to change the setpoint driver electrical impulses 2 includes a motor 3 in accordance with the set pulse control mode. The rotation of the motor 3 through the reduction gear 4 is driven drum 5, which in turn changes the length of the suspension rope 6 by winding it on the drum 5. At the end of the next pulse of control which it is served the next control pulse to the electric motor 3 and the setpoint change continues. The process ends with the achievement of specified water level in the downstream hydraulic structures.The efficiency of the device is ensured by the fact that in comparison with the known devices it is applied freely oriented in the flow of water float. This eliminates mechanical failures, increases the sensitivity of the device to changes in water level. The introduction of special control algorithm to drive the motor in change mode setting significantly reduces the power consumption of the device and extends its field of application is in remote control systems.Sources of information1.
