Description

A kind of seamless closing formula passive intelligent water meter based on NB-IOT

Technical field

The utility model relates to water meter technical fields, and in particular to a kind of seamless closing formula passive intelligent based on NB-IOT Water meter.

Background technique

Now most on the market is mechanical water meter, needs manually to carry out meter reading, time-consuming and laborious；Also part awards non- Small wireless water meter under frequency range is weighed, is easy to be interfered by outer signals, meter reading efficiency is low, error rate is high, and these water meter functions It is single, it can not grow with each passing hour, not adapt to intelligent social progress demand.

In addition, rotary vane meter on the market uses top, agate or corundum support construction at present, and when flowing water measures, leaf Wheel rotation is fast, and top, agate or corundum abrasion are big, and initial-flow is caused to rise, and water meter is walked slowly, and error deterioration, precision gradually becomes Difference not can guarantee accurate metering, can shorten the working life of water meter yet.

Summary of the invention

The purpose of the utility model is to overcome the defect of existing technology and deficiency, provide a kind of simple structure, long service life, The high seamless closing formula passive intelligent water meter based on NB-IOT of measuring accuracy.

In order to achieve the above object, the technical solution of the utility model is: a kind of seamless closing formula based on NB-IOT Passive intelligent water meter, including watchcase, current management block, control module and NB-IOT module, it is characterised in that: in the watchcase Portion is equipped with the hollow hydrostatic bearing passed through for water flow, and the inside of the hydrostatic bearing is equipped with shaftless blade, described shaftless The upper and lower lobes edge of blade is fixedly connected with the inner wall of hydrostatic bearing respectively, and the side of the hydrostatic bearing, which is arranged side by side, to be had and static pressure The magnet ring that bearing outer wall is fixedly connected, is provided with water stream channel in the watchcase of hydrostatic bearing surrounding, the magnet ring up and down two Induction coil is provided in the watchcase of side, the induction coil is electrically connected with current management block.

The induction coil, which is equipped with, draws connector, and the extraction connector is electrically connected with the input terminal of current management block, The output end of the current management block is electrically connected with the input terminal of control module, the output end and NB-IOT of the control module The input terminal of module is electrically connected.

Another end opening of the outside open at one end positioned at hydrostatic bearing of the water stream channel, water stream channel is located at static pressure Above or below bearing, the height of the watchcase is slightly larger than the height of hydrostatic bearing.

The utility model compared with prior art, has the advantage that

1, impeller is arranged in hollow hydrostatic bearing the utility model, and hydrostatic bearing is held up and rotated using water flow, Hydrostatic bearing is not contacted with surrounding, and for water flow as lubricant medium, the frictional force of bearing and peripheral wall is small, and abrasion, water is substantially not present Table long service life is arranged in the impeller inside hollow hydrostatic bearing and mechanical friction is not present, accuracy of water meter can be improved, Reduce initial-flow.

2, the ingenious setting pipelined channel of the utility model, carries out the suspension of hydrostatic bearing and rotation simultaneously, mentions The high measuring accuracy of water meter.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

In figure: watchcase 1, current management block 2, control module 3, NB-IOT module 4, hydrostatic bearing 5, shaftless blade 6, magnetic Iron hoop 7, water stream channel 8, induction coil 9 draw connector 10.

Specific embodiment

The utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.

Referring to Fig. 1, a kind of seamless closing formula passive intelligent water meter based on NB-IOT, including watchcase 1, current management block 2, control module 3 and NB-IOT module 4 are equipped with the hollow hydrostatic bearing 5 passed through for water flow inside the watchcase 1, in order to Hydrostatic bearing 5 is enabled to have sufficiently large space to suspend, the height of the watchcase 1 is slightly larger than the height of hydrostatic bearing 5, described The inside of hydrostatic bearing 5 is equipped with shaftless blade 6, and the upper and lower lobes edge of the shaftless blade 6 is solid with the inner wall of hydrostatic bearing 5 respectively Fixed connection, the side of the hydrostatic bearing 5, which is arranged side by side, the magnet ring 7 being fixedly connected with 5 outer wall of hydrostatic bearing, hydrostatic bearing Water stream channel 8, the outside open at one end positioned at hydrostatic bearing 5 of the water stream channel 8, water flow are provided in the watchcase 1 of 5 surroundings Another end opening in channel 8 is located above or below hydrostatic bearing 5, is provided in the watchcase 1 of about 7 two sides of magnet ring Induction coil 9, the induction coil 9, which is equipped with, draws connector 10, the input terminal for drawing connector 10 and current management block 2 Electrical connection, the output end of the current management block 2 are electrically connected with the input terminal of control module 3, the output of the control module 3 End is electrically connected with the input terminal of NB-IOT module 4.

The working process of the utility model is as follows: water flow enters from the inlet in watchcase 1, and is divided into before hydrostatic bearing 5 more Stock water flow, a part of tiny water flow are flowed into from water stream channel 8 respectively, and are flowed out respectively from the upper and lower of hydrostatic bearing 5, will Hydrostatic bearing 5 is held up, and intermediate main water flow passes through hydrostatic bearing 5, pushes shaftless blade 6 to rotate when passing through hydrostatic bearing 5, nothing The rotation of axis blade 6 will drive hydrostatic bearing 5 and magnet ring 7 rotates with it, in the course of rotation, the magnetic that magnet ring 7 generates Field can be by 9 cutting magnetic induction line of induction coil, therefore generates induced current, and induced current is transmitted to electric current by drawing connector 10 Management module 2 manages induced current by current management block 2, and sends current-voltage information to control module 3, controls mould On the one hand the effect of block 3 is that flow is calculated according to Current Voltage, flow information is transferred to by still further aspect control NB-IOT module 4 Receiving terminal.
