Background technology
At present, industrial flow instrumentation is of a great variety, structural shape is also varied, by detecting the principle branch differential pressure flowmeter, volumeter, float type flow meter, turbine meter, electromagnetic type flow meter, eddy currents flowmeter, ultrasonic type flowmeter, Coriolis-type mass flowmeter or the like is arranged.Wherein: volumeter is to utilize the mechanical measurement element that fluid continuously is divided into single known volume, repeatedly is full of and the number of times that discharges this volume fluid is measured the flow volume total amount according to measuring room; In order to adapt in the production requirement to the various different mediums and the different operating condition of flow measurement, volumeter can be divided into gear type again, scrape three kinds of patterns such as template and rotary-piston type, the wheeled flowmeter of waist is a kind of of gear type volumeter, it is by measuring room, gear train, integrator, the indication gauge outfit, Automatic Temperature Compensator, compositions such as automatic pressure compensator and sender unit, measuring room is made of a pair of waist wheel and housing, two waists wheel has the rotor of conjugate curves each other, with the coaxial driven wheel that is equipped with of waist wheel, measured flux promotes the rotor rotation, between rotor by driving gear drives; Gear train comprises shaft coupling and gear, and its weak point is: sender unit can send to data acquisition system (DAS) with flow parameter and manage concentratedly, but all needs external power supply, and signal also all is to transmit by wired mode.
The utility model content
Technical problem to be solved in the utility model provides a kind of wireless digital waist wheel volume-displacement, it not only can detect flow automatically, and dispense with outer connecting power and laying data acquisition cable, can directly obtain flow parameter, easy and simple to handle, stable performance is easy to use with the higher place of maneuverability requirement in the open air.
The utility model wireless digital waist wheel volume-displacement comprises waist wheel flow cell, and waist wheel flow cell is provided with transmission gear shift device, speed probe, main circuit and display, also comprises emitting antenna, shaft coupling and microgenerator.Wherein: emitting antenna links to each other with main circuit, and the output signal of main circuit is exported via the emitting antenna teletransmission; The main shaft of microgenerator links to each other by the output shaft of shaft coupling with the transmission gear shift device, is main circuit, display and emitting antenna power supply.
The utility model wireless digital waist wheel volume-displacement, wherein be connected to charging circuit and accumulator between microgenerator and the main circuit, the electric current that microgenerator sends is a charge in batteries through described charging circuit, and accumulator is main circuit, display and emitting antenna power supply.
The utility model wireless digital waist wheel volume-displacement, wherein microgenerator, charging circuit, accumulator and main circuit are installed in the airtight can.
Because the rotor in the measuring room rotates under the fluid pressure difference effect between its import and the outlet, carry out transmission by being installed in the outer transmission gear shift device of its housing, that is: generator is sending electric current and is being charge in batteries through overcharge circuit control with after handling under the driving of transmission gear shift device, and accumulator is main circuit, display and emitting antenna power supply again; Speed probe passes to display with detected flow signal and directly indicates flow after main circuit is handled simultaneously, and can realize the flow teletransmission; So have the utility model wireless digital waist wheel volume-displacement of said structure feature, do not need external power supply and lay the signals collecting cable, just can directly obtain integrated flow and instantaneous delivery on the fluid circuit, thereby realize the self-powered and the transmission of wireless signals of flow detection circuit, the flow that is particularly suitable for the higher place of field or maneuverability requirement detects automatically.
