Description
Technical field
The present invention relates to water meter, more specifically relate to the water meter of digital electronic unit with clearance transmission mechanism.
Background technology
Water meter now, the number system that also has watt-hour meter, gas meter, flow meter all is to adopt decade count, and all be to realize by gear drive, this gear train is used for indication, all be connected a dial on the gear shaft as individual position, ten, hundred and kilobit, it is marked with 0,1,2 ... 9, not that the collocation by ratio of gear realizes between the isotopic number.When the dial of individual position by 0,1,2 ... forward 9 to, again and then get back to 0, that is to say, user's water consumption, perhaps electricity consumption, gas consumption reaches 10 measurement units, at this moment the dial of representing ten will turn to 1 from 0, based on gear drive is a kind of continuous kind of drive, so when the units letter disk was rotating, the dial of ten, hundred and kilobit was also all followed rotation.For instance, when the units letter disk rotates 360 °, the tens letter disk will rotate 36 °, and hundred dials with kilobit have then rotated 3.6 ° and 0.36 ° respectively, consequently make inconvenience to reading on the one hand, turn to 7,8 or 8,9 position as the units letter disk, the tens letter disk is the numeral of carry, and for example 1, almost taken the reading window, easily misread into 1.8 or 1.9, misread thereby cause with 0.8 or 0.9.The transmission resistance of main is whole gear drive itself is big, and in order to make the driving force that gear drive rotates just needs to increase the driven wheel gear train, this directly influences the measuring accuracy of water meter or ammeter, gas meter, flow meter.Also require to improve the manufacturing accuracy of gear for this reason, reduce the friction force between axle and bearing as far as possible, thereby improved manufacturing cost.On November 17th, 1999, disclosed Chinese patent CN2349548Y disclosed a kind of " ratchet digital direct-reading type water meter ", it has increased a ratchet between the gear shaft of the dial connection of individual, ten, hundred of expressions and kilobit, this just makes that dial no longer is continuous rotation, but step-type rotation, thereby improved the accuracy of reading, but still can not solve the crucial big problem of gear train resistance.
Summary of the invention
The object of the present invention is to provide a kind of water meter that can overcome the digital electronic unit with clearance transmission mechanism of prior art defective.
The said water meter of the present invention with digital electronic unit of clearance transmission mechanism, comprise a watchcase, the bottom of watchcase splits into, outlet conduit, be provided with impeller therebetween, the output shaft of impeller is through the first transition gear group, be connected to the second transition gear group by magnetic force then, the second transition gear group is connected with the gear train of counting assembly, the gear train that it is characterized in that said digital electronic unit is made up of the striking gear of a plurality of expression varying number levels and the device that is struck, and the striking gear of the same order of magnitude and the device that is struck link into an integrated entity, wherein, be struck device and the striking gear of minimum magnitude digital electronic unit all are first gears of the second transition gear group, the device that is struck of the digital electronic unit of the inferior low order of magnitude is last gear of the second transition gear group, and maximum quantity level digital electronic unit only contains the device that is struck; Resistance dish and a reading device that detects each resistance dish resistance value are housed on a plurality of striking gears that fuse and the device that is struck whole or in part.According to the present invention's said " order of magnitude " is to define by decimal carry.For example, one of percentage position, 1/10th, individual position, ten, hundred and kilobit.Used order of magnitude when the present invention said " partly " is digital examination user actual used water amount is generally a position to kilobit.
According to a preferred embodiment of the present invention, said striking gear is a dead man, and the device that is struck is to be contained in uniform column on the same circumference of a disk.
According to another preferred embodiment of the present invention, said striking gear is a driving lever, and the device that is struck is a driver chuck.
According to the water meter of the said electronics digital electronic unit with clearance transmission mechanism of the present invention in use, water enters and promotes wheel rotation from inlet channel, flows into user's the water end (W.E.) of using then through the outlet conduit of water meter.First gear of the first transition gear group is equipped with on the top of impeller shaft, after this gear set speed change, its last gear the axle the top one magnetic patch is housed.A magnetic patch also is equipped with in magnetic patch position on the top of the axle of last gear of the corresponding first transition gear group below the axle of first gear of the second transition gear group, realizes that the first transition gear group transmits moment of torsion to the second transition gear group thereby connect by magnetic.The advantage of doing like this is can be with the first transition gear group and the second transition gear group, and digital electronic unit separates with the water proof device, that is to say, the second transition gear group and digital electronic unit can be in work under the dry type state, this will help prolonging the serviceable life of water meter, and easy to use, care and maintenance.
According to the first transition gear group of the present invention is a reduction gear, that is to say, the rotating speed of first gear of this gear set is higher than the rotating speed of last gear.To help like this transmitting moment of torsion to the second transition gear group.
Upwards increase progressively step by step to the maximum quantity level by the minimum magnitude according to digital electronic unit of the present invention, and be by decimal carry.Increase progressively by following rule to advance level than its high order of magnitude by a low order of magnitude, that hangs down the order of magnitude enters 9 by 0, only rotate the device that is struck of the low order of magnitude, when entering 10 by 9, the device that is struck that the striking gear of the low order of magnitude is stirred the order of magnitude number that makes it to advance, for example, enter 1 by 0, this moment, the device that is struck of the low order of magnitude then got back to 0.This process, that is to say, the device that is struck of the low order of magnitude rotate 360 ° (promptly from 0,1,2 ... 9 return 0), only go to original number from original number adds 1 position to the device that is struck of its high order of magnitude, for example, forward 1 to from 0, just only changeed 36 °, and can not stir for the striking gear of its previous order of magnitude than the device that is struck of its higher order of magnitude.
When detecting user's water consumption, described electronical reading device detects the resistance value of all or part of resistance dish, and the result that will detect and the comparison of standard electric resistance and through being converted into user's water consumption, be sent to relevant department by transmitting device, for example, water-supplying unit, and charge in view of the above.Be remote examination water meter, and then realize paying dues at a distance that provide may.
Obviously, water meter with digital electronic unit of clearance transmission mechanism of the present invention adopts the digital electronic unit with clearance mechanism, it has overcome in the prior art because this big defective of resistance that adopts the counting assembly of gear drive to bring, because this advantage, the transition gear group of winning can be reduced to the moment of torsion of the second transition gear group transmission, thus the sensitivity that has improved water meter.On the other hand, owing to adopted clearance transmission mechanism, make it simple in structure comparing, reduced requirement, thereby also reduced cost machining precision with gear drive.Owing to adopted the electronical reading device also will reduce the input of manpower and materials widely.
