Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The utility model relates to a turbine formula flow monitoring device, the device includes shell 1, and 1 left end of shell is delivery port 10, and the right-hand member is water inlet 9, is provided with turbine formula rotor subassembly between 1 inside delivery port 10 of shell and the water inlet 9. The turbine formula rotor subassembly includes T type plastic part 4, connecting rod 3 and turbine 2, and 2 vertical settings of 2 axial of turbine are between delivery port 10 and water inlet 9, and 2 tops of turbine are connected to T type plastic part 4 through connecting rod 3 on, and the bar inslot that 13 top surfaces of T type plastic part were seted up is provided with magnet 6, and 13 one sides of T type plastic part are provided with hall sensor 5. The bottom of the shell 1 is provided with a drain outlet 7, and the drain outlet 7 is provided with a plug 8. The casing 1 is provided with a glass window 11, and the water flow and the turbine operation condition of the inner pipeline can be seen.
The top is provided with turbine formula rotor subassembly support in the shell 1, cavity and bottom trompil, and T type plastic part 4 is located the support intracavity, and connecting rod 3 inserts in the support trompil.
And an RS485 interface for communicating with external equipment is arranged on the Hall sensor 5. The Hall sensor 5 can also send a control command to the current signal special chip AD694 through a singlechip of the instrument part to generate a 4-20mA analog quantity signal. The function is to communicate with the upper computer. The current type analog quantity signal has strong anti-interference, and is the most common communication mode among hydropower station equipment. In addition, a single chip microcomputer in the instrument collects signals transmitted by the Hall sensor, processes the signals and converts the signals into flow information, the flow information is compared with an alarm value set by a user, and if the flow information is larger than the alarm value, a peripheral relay is closed to give an alarm.
When liquid flows through the flow monitoring device installed in the pipeline, the liquid can drive the turbine 2 inside the device to rotate, the turbine 2 drives the T-shaped plastic part 4 above the T-shaped plastic part through the connecting rod 3 to rotate synchronously, and meanwhile, the magnet 6 on the T-shaped plastic part 4 is monitored by the Hall sensor 5.
The information collected by the Hall sensor 5 can be collected, then the rotating speed under different flow rates is obtained through calculation, the rotating speed and the actual flow rate (measured by a water meter) are corresponded according to a certain proportion, and the proportion coefficient is set through a key on the device, so that the actual flow rate of the current pipeline can be obtained; then the device can be additionally provided with a display module to display the information through an LED nixie tube for a user to check, and can be communicated with external equipment through an RS485 interface and can also output 4-20mA analog quantity signals. In the case of setting the alarm point values, corresponding switching values and alarm contacts can also be output after the flow has reached these values.
The single chip microcomputer and the LED nixie tube can be arranged at the top of the device shell and are displayed in an instrument mode, and the instrument part can comprise the single chip microcomputer, the LED nixie tube, an alarm relay, a 4-20mA circuit and an LED lamp.
