In order to improve induction precision of the inner impeller to water flow impact pressure, the water blockoff lid 17 is cone shell shape；It is described
The circular cone concave face of water blockoff lid 17 is towards the inside of quill 3.Water blockoff lid 17 can further increase after using cone shell to flow
The induction precision of impact force improves the susceptibility to water flow, is convenient for the conversion of out rotor and inner impeller.
Preferably, first transmission shaft 25, second driving shaft 7 both pass through after 14 roof of installation cavity with corresponding inductive disks
29 connections；The inductive disks 29 are arranged in seal box 28；The seal box 28 is disc-shape；28 side wall of the seal box is
It is double-deck；The Hall sensor 32 is arranged in interlayer；The circuit system 30 that the Hall sensor 32 passes through electric wire and upper end
Connection.28 side wall of seal box is arranged to double-layer structure so that inductive disks 29 are in different sealants from Hall sensor 32
In, therefore Hall sensor 32 and the circuit of cooperation can be opened with water segregation completely, improve the water proofing property of monitoring device, be stablized
Property.
Preferably, the installation cavity 14 is provided at both ends with mounting bracket 5；3 both ends of described sleeve pipe axis are arranged on mounting bracket 5.
The specifically used principle of the present invention：
Flow passes through total process：Flow enters from water inlet 12, after filter screen 41 after inner impeller 2 and out rotor 4 monitor,
It is flowed out from the water outlet 1 of lower end.
The monitoring principle of small flow flow：For flow after the entrance of water inlet 12, the flow into out rotor 4 can be by bottom
Water blockoff ring 16 is blocked, and can not be passed through；And the flow of sleeve pipe axis 3 pass through inner impeller 2 when, can drive inner impeller 2 rotate, internal lobe
Wheel 2 drives the first transmission shaft 25 rotation on top, to drive inductive disks 29 to rotate, magnet 36 and hall sensing in inductive disks
Device 32 occurs induction and is passed to signal in the circuit system 30 of upper end by electric wire.
Since small flow water flow impact pressure is small, water blockoff lid 17 can not be pushed；The vertical steel bracket ring 37 of 16 top surface of water blockoff ring
It is engaged with the lower tooth torus 9 of 3 lower end of quill always so that out rotor 4 can not rotate.
With the increase of water flow, flow pushes water blockoff lid 17 to continue to decline, promotes water blockoff lid 17 when water flow increases to
After dropping to preset distance, hairspring 24 is compressed, and thin axis 23 pushes down on the decline of lifting tube 21, and bulky spring 19 is also compressed,
Lifting tube 21 drives water blockoff ring 16 to decline, and vertical steel bracket ring 37 is disengaged from lower tooth torus 9, and since water blockoff ring 16 declines, makes
The flow obtained in out rotor 4 can flow downward out, and thus out rotor 4 be driven to rotate, and due to the decline of rotary shaft 26 so that rotation
The spline structure on 26 top of axis unclamps, and the first transmission shaft 25 is separated from rotary shaft 26, and the first transmission shaft 25 stops rotating at this time,
Circuit system can not receive the rotating signal of inner impeller 2；And the rotation of out rotor 4 can drive driven tooth by ring gear 13
6 rotation of wheel, driven gear 6 drive second driving shaft 7 to rotate, and second driving shaft 7 drives another inductive disks 29 rotation of upper end
Turn, the circuit system 30 that signal is passed to upper end by induction by electric wire occurs with Hall sensor 32 for the magnet 36 in inductive disks
In.
When rotary shaft 26 declines due to water flow increase, face of gear and 10 upper surface of lantern ring of 27 bottom surface of gear platen
Face of gear engagement, inner impeller 2 drives lantern ring 10 to rotate, while generating downward pressure to lantern ring 10 so that brush stroke 38 is pressed
It is tightly rotated on filter screen 41, the sundries accumulated on filter screen 41 can be brushed rapidly, be drained into inclined ramp 43, most
After drop into slag trapping cavity 39 and be collected, user can timing opening scum pipe 40, sundries is cleaned up.
In order to enable the sundries disposed on filter screen that 38 energy of brush stroke is lasting, can be arranged water wheels leaf on lantern ring 10
Piece 44 is rotated using the flow driving turbine blade 44 of flow, and what such brush stroke 38 can continue scrapes on filter screen 41
Sundries, but due to lacking pressure of the gear platen 27 to lantern ring 10, brush stroke 38 at this time, which can only understand, falls filtering
Online some loosening junks and sundries is dispersed, really realize the efficient removing of sundries or needs the band after inner impeller 2 declines
The rotation of 38 crushing failure at high speed formula of electric brush bar could be realized.
Since the out rotor 4 in the present invention can voluntarily adjust startup from inner impeller 2 according to different water flow sizes, flow
Start out rotor when measuring big, although inner impeller is rotating, idle running；Flow hour, out rotor stop rotating, and inner impeller opens
It is dynamic, transmit a signal to circuit system 30；The independent monitoring of small-large flow is realized as a result of coaxial interior out rotor, therefore is supervised
Survey is more reliable and more stable, and monitoring result is more accurate, and since circuit system is the signal of two impellers of individual reception, because
This signal processing is simpler reliable and stable.
Moreover, in the case where out rotor stops rotating state, the out rotor lower end water ring 16 that is blocked is blocked, therefore flow at this time
It is flowed out after all having to pass through inner impeller 2, therefore the testing result of small flow flow can be very accurate and reliable.
There is also the advantages of an accident to be by the present invention：It can prevent user from carrying out water steathily, when user opens tap very
Hour, flow, which can be oozed slowly, to be come, but actually water meter is not run, therefore water is freely used；And the present invention
Device is due to being provided with water blockoff ring 16 and water blockoff lid 17, so if tap is opened very little by user, it is desirable to which flow is slow at water droplet
When slug flow goes out, since flow rate of water flow is inadequate, the pressure of hairspring 24 is more than the impact force of flow, and water blockoff lid 17 can not be rushed to open
Namely flow be plugged in the present apparatus, will not flow out and, therefore cannot achieve water steathily.
It should be noted that herein, the terms "include", "comprise" or its any other variant are intended to non-row
His property includes, so that the process, method, article or equipment including a series of elements includes not only those elements, and
