Abstract
A passive electric display flow-meter relates to measurement and display device of water flow for realizing long distance transmission and on-line of measured data signals characterizing in mounting a micro-generator in the shell of a flow-meter and turning water flow energy to electric signals then to become water flow value after compensating by operation circuit to be display on the screen of a flow-meter. The device can store and transmit data.
Description
Technical field the present invention relates to a kind of passive electronic display flowmeter, the flow measurement of especially a kind of self power generation, power supply and the flowmeter of demonstration.
Background technology uses the most general water meter to belong to a kind of mechanical type water meter that is driven one group of gear and mechanical count mechanism by impeller now.Also having a kind of is value stored type, and it is that stem-winder shows mixture with electricity, and it is by the mode by user's anticipate payment, the quantity of the buying water mode with electronic data is stored in the water meter, when the water of being buied was used up, solenoid valve will cut out flowmeter, and pointed out the user with this.
A kind of passive electronic display flowmeter that summary of the invention is involved in the present invention is a kind of device that utilizes the kinetic energy generating of current in the water pipe and show flow, and its course of work does not need additional power source.
It specifically is constructed as follows: impeller is contained in the kuppe, is connected with a generator amature with impeller is coaxial, an insulated enclosure lid is housed below in gland, and circuit, display screen are installed in the insulated enclosure side of covering.The rotor pivot is contained in the axis hole of the following center of insulated enclosure lid, and the following pivot of rotor is contained in the pedestal of the center below the kuppe.Coil winding, iron core are assemblied in the inner ring surface on flowmeter shell top.Side at the insulated enclosure lid has pair of electrodes to pass.Between the lower edge of insulated enclosure lid and flowmeter shell O-ring seal is housed.
With the impeller tube of impeller one with the parallel horizontal axis line place that is installed on flowmeter shell of flowmeter shell, rotor is equipped with at the outer ring surface place of impeller tube, flowmeter shell is formed through the shell flange butt joint by two parts, and winding and iron core are in the both ends of the inner ring surface of flowmeter shell.Flowmeter shell is a butt joint cylindrical shell in the middle of cylindrical shape, and a display screen is housed above flowmeter shell, is connected by pair of electrodes between display screen and winding, is separated by the insulated enclosure cover between electrode and flowmeter shell.Vertical pedestal is installed in the both ends of flowmeter shell inner chamber, is sealed by O-ring seal between shell flange.The impeller inner edge is connected with armature spindle, and outer rim is connected with the impeller tube.Its advantage is that this flowmeter does not need additional power source, and flow is accurate.
Description of drawings Fig. 1 is the axial cut-open view of embodiment 1; Fig. 2 is the axial cut-open view of embodiment 2.
Embodiment in the embodiment shown in fig. 1, outside planform and flowmeter shell 16 glands 1, kuppe 12, impeller 13 grades are all identical with water meter structure of the prior art, and the position of having only the top of impeller that speed gear group and mechanical counter were installed is originally replaced by the rotor 7 of microgenerator and coil winding 5, iron core 6.Impeller 13 is coaxial with rotor 7, pivot 8-1 is installed in the axis hole 8-2 of insulated enclosure lid 10 following centers on the rotor, the following pivot 17 of rotor is installed in the pedestal 15 at kuppe 14 bottom centre place, the electric current that coil winding 5 produces flows to the circuit 3 that signal Processing is used by the pair of electrodes that is installed on insulated enclosure and covers 10 bottoms, send display screen 9 then to and be used for direct-reading, also can teletransmission give the Data LAN Management Centre.In this embodiment of Fig. 1, gland below 2 is windowpanes, the 11st, and O-ring seal, the 14th, the pod apertures on the kuppe 12 utilizes this hole that current rotation impeller 13 is rotated, and then drives rotor 7 rotation generatings.
Figure 2 shows that an alternative embodiment of the invention, in this embodiment, primary structure and principle of work are substantially the same manner as Example 1, all be that the rotor 7 that utilizes current to drive microgenerator rotates the generation electric current, utilize the corresponding relation of this electric current and discharge again, be converted into suitable electric signal by corresponding circuit, direct-reading on display screen 9.
In Fig. 2, impeller 13 is horizontal installation, 13 li edge of impeller are connected with impeller shaft 8, outer rim is connected with impeller tube 21, and the three is structure as a whole, on the two vertical pedestals 18 about rotor pivot 8-1 is installed in respectively, rotor 7 also is fixed on the impeller tube 21 middle part outer ring surfaces, two vertical pedestals are wheel shape, and porous is beneficial to current and flows through, and are fixed on two ends in the flowmeter shell 16.Coil winding and iron core 6 are installed in the two ends of the cylindrical cavity of flowmeter shell 16, are positioned at the both sides of rotor 7, the electric current that coil winding 6 produces by a pair of motor 4 on the flowmeter shell 16 be transferred to be installed in flowmeter shell 16 tops display screen 9 so that direct-reading.This is permeate water watch shells 16 to electrode 4, and seal through insulation sealing shroud 20.Embodiment 1,2 two ends all have external thread to be connected with existing water pipeline is convenient.
