Specific embodiment
The structure of the utility model is further illustrated with reference to the accompanying drawing.It describes shown in attached drawing and with reference to the accompanying drawings
The embodiments of the present invention be only exemplary, and the utility model is not limited to these embodiments.Also need
It is noted that in order to avoid having obscured the utility model because of unnecessary details, illustrate only in the accompanying drawings and basis
The closely related structure of the embodiment of the utility model, and the other details little with the utility model relationship are omitted, these are thin
Section can be known from the prior art or from the structure of the disclosed water meter of applicant.
Embodiment 1: it as shown in Figure 1, a kind of counting mechanism described in the utility model, including upper clamp plate 1, lower clamp plate 2, sets
The pointer 3 being placed in upper clamp plate and the machine core gear set 4 between upper clamp plate and lower clamp plate, machine core gear set 4 include and leaf
It takes turns the central gear 41 of transmission connection, be sequentially connected with the first counting gear group of central gear transmission connection, with central gear
For incude reading the second counting gear group, the second counting gear group include with central gear 41 be sequentially connected first count
Number gear 401, and the second counting gear 402 with the transmission connection of the first counting gear, the second counting gear 402 pass through gear
Column and reading pointer 31 are sequentially connected, and the second counting gear 402 is coaxially disposed with reading pointer 31.
Reading pointer 31 is non-magnetic rustproof steel disc, and it is that arc is stainless that reading pointer 31 goes out in wheel group radially around in machine core
Steel thin slice, receives as electromagnetism and trigger mechanism forms electromagnetic echoes when detection electromagnetic wave is dealt into magnetism-free stainless steel thin slice,
Emitted frequency, phase and amplitude are changed, so that transmitting circuit generates sampled signal, output digit signals after processing are completed
Water meter electronical reading.
Compared with traditional non-magnetic intelligent water meter, the utility model is referred to by the reading being sequentially connected with machine core gear set 4
Needle 31 does not influence the normal reading of the mechanical character wheel metering of water meter, while the reading of water meter being passed through to the variation of reading pointer 31,
Complete digital signal output.It avoids and the reading pointer without magnetic is set in vane edge in the prior art, turned by measurement impeller
Dynamic circle number obtains fluid flow, but the setting reading pointer at impeller, interferes the normal reading of water meter, and it is straight to read pointer
It connects and is connect with impeller, the external environment of impeller is complicated, and suffered disturbing factor is more, influences the accuracy of electronical reading.Directly and leaf
Wheel connection cannot achieve accurately electronical reading.
Further, as shown in figure 3, the connection type of reading pointer and machine core gear set can divide it is a variety of, specifically, the
One counting gear group includes the gear 403 connecting with central gear, gear 404, gear 405, gear 406, gear 407 and gear
408, the first counting gear group completes the mechanical character wheel metering of water meter, artificial reading is realized, by reading pointer 31 and gear 408
Transmission connection can also realize electronical reading, but this kind of connection type reads the error propagation of water meter mechanical reading to electronics
Number.Further, since intermediate drive gear increases, the probability that electronical reading generates error is increased.
Further, if electronical reading is realized in induction pointer 31 and the transmission connection of central gear 41, this kind of connection type connects
Connecing can be because central gear 41 be directly connected with impeller, and undermoderated causes the phase-shifted of induction pointer 31 excessive, causes to read
Number is inaccurate, and induction indicators turn is too fast, and damage is excessive, influences the service life of water meter.
Therefore central gear 41 is sequentially connected with the first counting gear 401 first in the utility model, tentatively slowed down,
Second counting gear 402 and the first counting gear 401 are sequentially connected, and reading pointer 31 is set on the second counting gear 402,
Mechanical reading is neither influenced, and can accurately realize electronical reading, and error probability is small and water meter long service life.
It can be seen that mechanical reading and electronical reading from the structure of the utility model to be counted with separated gear set,
First be when leaving the factory, can carry out exfactory inspection to water meter, by electronical reading and mechanical reading, form a prompt judgement water meter
Qualification rate；Second does not interfere with each other for two kinds of counting modes, can accurately realize the counting of two ways；Third is also logical
Two kinds of separated counting modes are crossed, realize the calibration of reading, the exception that discovery water meter counts.
Above-mentioned counting mechanism is applied in water meter, mechanical count and electronic counting can be achieved at the same time, working principle is such as
Under:
Linkage part in impeller shaft is connected with counting mechanism, and when water flow enters from the inlet, driving impeller rotates, leaf
Central gear on the driven impeller axis of wheel is meshed with first gear 403 of the first counting gear group, counts tooth by first
Wheel group realizes speed change, records wheel speed, indicates the water for flowing through water meter on scale by pointer, realizes mechanical
It counts the first counting gear 401 to be sequentially connected with central gear 41 simultaneously, impeller is then transmitted by the second counting gear 402 and is turned
Speed, by reading pointer 31 realize position signal reading, sensor will collected position signal, be sent in mainboard
Position signal is converted to wheel rotation circle number, completes electronical reading by controller by the calculating of controller.
The utility model realizes the mechanical reading and electronical reading of water meter by the improvement to machine core gear set.For
Realize that the second counting gear group of electronical reading by the rotation of impeller, is transmitted to reading pointer, wherein during electronical reading
Data transmission and calculating are all made of state of the art and conventional technical means and can be realized.The utility model protection is to answer
It is further the machine core gear set in counting mechanism for the counting mechanism in water meter.Above embodiments are to the utility model
Do not constitute restriction, relevant staff in the range of without departing from the utility model technical idea, carried out multiplicity variation and
Modification, each falls within the protection scope of the utility model.
