Description
Technical field
The utility model proposes a kind of permanent magnetism coil self-generating devices, and in particular to pumping unit indicator for Denso
It sets.
Background technique
Pumping unit is that most important lifting equipment in rod pumping system according to Pumping Unit feature can be divided into walking beam
Formula pumping unit and without beam pumping unit.Since the advent of the world, beam pumping unit occupy always absolute dominance.It is main special
Point is that structure is simple, applied widely, reliability and durability, manufacture maintenance cost is low, technology maturation.Beam pumping unit, refer to containing
Walking beam is commutated by link mechanism, and the pumping unit of crank weight balance is commonly called as kowtowing machine.Mainly by horse head-walking beam-company
The most of composition of bar-crank mechanism, reduction gearbox, power-equipment and auxiliary equipment etc. four.When work, the transmission of motor is through becoming
Fast case, crank link mechanism become the up and down motion of horse head, and horse head drives on the plunger work of downhole pump through polished rod, sucker rod
Lower movement, so that the crude oil in well is constantly extracted out pit shaft.
It in the pumping unit course of work, needs to judge the working condition of pumping unit well pump, at this moment indicator is just needed to carry out
Auxiliary detection and supervision.Indicator is a kind of instrument that combined load measurement, displacement measurement, less radio-frequency, GPRS technology are integrated
Device, can automatic collection pumping unit load, stroke calculates function diagram data, it is independent or by with live RTU remote-terminal unit
Long-range function figure monitoring is realized in cooperation.Indicator card can be measured by indicator, indicator card is to judge pumping unit well pump working condition
Important means.Pumping-unit workdone graphic is the relation curve of oil-extractor polish-rod load and displacement, some documents are mentioned directly at present
Maneuvering load sensor measures light rod load, also has the document to mention the indicator card indirect method of measurement.
Pump unit dynamometer is mainly using the mode of wireless transmission at present, and main mode has battery in terms of power supply
Power supply, the mode that solar powered and lithium battery adds solar panels to power.Traditional battery is powered unavoidable to be replaced
Trouble, in primary replacement, pumping unit must be shut down, this greatly reduces production efficiency, and service life is shorter, and too
In the case where continuous rainy weather does not have sunlight in several days in succession, solar panel can not generate the power supply mode of positive energy solar panel
Lasting electric energy, the method that in addition also someone is combined using solar power generation and natural wind power generation, the combination of two methods
It can be improved the stability of power generation, actually this method can also encounter long-term calm and cloudy situation, will cause and show function
The power supply instability of device further will lead to the shutdown of pumping unit, and oil field stops production, and cause huge economic loss to enterprise.
Summary of the invention
In order to solve the powerup issue of km deep well machine indicator sensor, the utility model provides one kind and is based on
The pumping unit indicator power supply unit of permanent magnetism coil power generation, obtains energy using sucker rod in up and down motion, can guarantee to show
Power supply of the function device under different weather and different working environments, and its structure is very simple.
The technical solution adopted by the utility model to solve its technical problems is that: the power supply module of the utility model directly and
Indicator is packaged together, and is directly coupled with beam hanger for pumping machine by U-shaped opening, and U-shaped mouth designs so that power generation dress
It sets and cooperates conveniently with wirerope, do not need to penetrate from wirerope both ends, it is convenient and efficient, and bear to carry by indicator by polished rod eye
Lotus.It is characterized by: iron core is cylindrical in the stator core construction of a cylindrical body, multiple annulus are machined in cylinder
Shape slot has inlayed embedded stator winding on slot, and the interval between slot becomes tooth, and slot and tooth can increase magnetic conductivity, promotes power generation
Performance.The part of linear motion is known as mover, and mover is made of mover magnetic yoke and multiple annular poles, is mounted on d-axis, magnetic
Yoke is the good magnetizer overlayed on d-axis, is the flux path between magnetic pole, and the thickness of annular poles is identical as the stator facewidth.Mover
Both ends are connected separately with spring, and the other both ends of spring are connect with cylindrical body both ends of the surface, when indicator be in it is static when, mover in
Middle position balance.
During pumping unit works normally, velocity and acceleration is variation during the up and down motion of sucker rod
, since inertia force to generate vibration between mover and spring, mover and stator is made to generate relative motion.Conducting wire cutting magnetic induction is answered
The electric energy that line generates, is output to accumulators store after rectification circuit is handled, guarantees the normal work of sensor.And when oil pumping
When machine stops working, although at this moment power generator stops vibration, mover and stator no longer generate relative motion, no electric energy production,
But indicator does not also work at this time.When pumping unit rework indicator need electric energy when, power generator with sucker rod fortune
It moves and vibrates, so that power generator produces electricl energy.
The beneficial effects of the utility model are: solving the powerup issue of km deep well machine indicator sensor, energy
Enough guarantee power supply of the indicator under different weather and different working environments, and its structure is very simple, not by weather
Etc. factors influence, jamproof ability is strong, be able to maintain sensor stabilization operation.
