Description
Technical field
The present invention relates to water meter fields, and in particular to a kind of intellectual water meter is combined using Magnetic drive with no magnetic sensing
Mode guarantees the accuracy counted.
Background technique
Intellectual water meter is seen everywhere, and the counting mode of intellectual water meter mainly uses no magnetic sensing mode in the prior art, i.e.,
Half-turn steel disc (steel foil) is added on the pointer of conventional water meter, is placed in magnetic field, counting principle is as follows: when indicators turn,
Cutting magnetic line simultaneously generates pulse current, and the movement of pulse current trigger sensor shows the dosage of water with the change of reading.
But current sensor because magnetic field strength deficiency and reduce the comprehensive consideration of cost, generally can only with steel disc
It can guarantee the accuracy counted in the range of (steel foil) radius 6mm, it will cause the data of reading are inadequate more than this distance
Accurate problem.Because current intellectual water meter is all on conventional water meter plus sensor, and the machine core of conventional water meter and biography
One layer of glass is necessarily separated between sensor, under normal circumstances glass with a thickness of 4mm, consider further that water meter movement, sensor and glass
The reality that glass cannot be close to completely, the installation space that sensor receives data is limited, is substantially at critical distance, directly will
Cause the data read inaccurate.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of intellectual water meters, next do further to the technical program
It illustrates.
The technical problem to be solved by the present invention is to existing intellectual water meter count when, because between machine core and sensor necessarily every
Under the reality that some glass and water meter movement, sensor cannot be close to completely with glass, sensor can not be counted accurately
Number；Concrete scheme is as follows: a kind of intellectual water meter, including machine core, pointer, Magnetic drive mechanism and non-magnetic sensor, and pointer is forever
Magnet is made and is set to inside machine core, and Magnetic drive mechanism is set to above glass；The Magnetic drive mechanism includes shaft, is fixed at
Cutting part and the permanent magnetic portion close in shaft and with glass, permanent magnetic portion in shaft attract each other with pointer, cutting part
With shaft rotation and cutting magnetic induction line；Non-magnetic sensor and cutting part are electrically connected to form closed circuit.
Further, the cutting part is fan-shaped steel disc, and the center of circle of fan-shaped steel disc is set on the axis of shaft.
Further, the fan-shaped steel disc is semicircle steel disc, and the center of circle is set on the axis of shaft.
Further, the pointer, permanent magnetic portion is close to glass but there are gaps.
Further, the permanent magnetic portion is a block permanent magnet, and the permanent magnet is just being set to the vertical direction of pointer.
Further, the permanent magnetic portion includes two block permanent magnets, and the resultant force of two block permanent magnets and pointer drives Magnetic drive machine
Structure and pointer rotate synchronously.
Further, the centre distance of two block permanent magnet is identical as the diameter of pointer, and one of permanent magnet is just
Set on pointer vertical direction.
The utility model has the advantages that compared with prior art, non-magnetic sensor is set to above permanent magnetic portion by the present invention, since no magnetic senses
Device can be arbitrarily arranged at a distance from steel disc or steel foil, break through the mounting distance limitation of the prior art, and counting can be very smart
Really, it solves the problems, such as to cause to count inaccuracy since distance is excessive between sensor and pointer.
Detailed description of the invention
Fig. 1: the structural schematic diagram of the present apparatus.
In figure: 10- machine core, 11- glass, 20- pointer, 30- Magnetic drive mechanism, 31a- permanent magnet, 31b- permanent magnet, 32-
Shaft, 33- steel disc, 40- non-magnetic sensor.
Specific embodiment
A specific embodiment of the invention is set forth now in conjunction with attached drawing.
A kind of intellectual water meter, the machine core 10 for being fixed with transparent glass 11 including top, the pointer inside machine core 10
20, positioned at the Magnetic drive mechanism 30 of the glass outer of machine core 10 and with Magnetic drive mechanism 30 close to non-magnetic sensor 40；Refer to
Needle 20 is set to 10 inside of machine core and close to glass 11 but there are gap, and pointer 20 is made of permanent magnet, turns under the promotion of water flow
Move and formed the magnetic field of rotation；Magnetic drive mechanism 30 close to glass 11 but also there are gap, shorten with permanent magnet pointer 20 away from
From Magnetic drive mechanism 30 is rotated with the magnetic field of rotation, and permanent magnet pointer 20, Magnetic drive mechanism 30 make magnetic field close to glass 11
Line is intensive, and the strong magnetic force of generation guarantees the synchronous rotation of permanent magnet pointer 20 and Magnetic drive mechanism 30.
Magnetic drive mechanism 30 includes vertically disposed shaft 32, the steel disc 33 being fixed in shaft and is set under shaft
It holds and is located above glass and close with glass spaces permanent magnet 31a, 31b, the steel disc 33 is constituted with non-magnetic sensor 40
Closed circuit；The permanent magnet 31a and permanent magnet 31b with rotated synchronously under the magneticaction of permanent magnet pointer 20, go forward side by side one
Step drives steel disc 33 to rotate, and cutting magnetic induction line simultaneously generates pulse current, and pulse current triggers non-magnetic sensor in closed circuit
40 count.
33 cutting magnetic induction line of steel disc is used in the present embodiment, can be used cut made of other conductors in other embodiments
The cutter device for cutting device or other shapes is not limited to steel or sheet.
As a preferably embodiment, in the present embodiment, center between the permanent magnet 31a and permanent magnet 31b away from
It is identical from the diameter of pointer 20, also, one of them such as permanent magnet 31a is just being set to 20 vertical direction of pointer, so increases
Resultant force between permanent magnet 31a, 31b and permanent magnet pointer 20 guarantees big synchronous rotation power.
It proposes, in another embodiment, Magnetic drive mechanism 30 can be provided only with a permanent magnet 31, and be located at pointer 20
Surface also can reach technical goal.
Working principle: water flow drives pointer 20 to rotate, and the pointer 20 of permanent magnet material attracts being set to for permanent magnet material to turn
Permanent magnet 31a, 31b of 32 lower end of axis are rotated synchronously, so that Magnetic drive mechanism 30 rotates synchronously, steel disc 33 rotates synchronously therewith,
And cutting magnetic induction line generates pulse current, triggers non-magnetic sensor 40 by closed circuit and counts, completes the meter to water flow
Number.
In the present embodiment, non-magnetic sensor 40 is set to the top of permanent magnetic portion 31, non-magnetic sensor 40 and steel disc 33 away from
From can arbitrarily be arranged, i.e. the mounting distance limitation of the breakthrough prior art can be very accurate so that counting, solve due to
The excessive problem for causing to count inaccuracy of distance between non-magnetic sensor 40 and pointer 20.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
