Description
Technical field
This utility model relates to gatage detection field, particularly a kind of gates of segmental shape Measuring opening device.
Background technology
These technical schemes following that what gates of segmental shape aperture measurement method was the most most widely used mainly have:
1, for fluid pressure type gates of segmental shape, driving gate opening, the liquid of closedown are measured by draw-wire displacement sensor
The displacement of oil pressuring cylinder piston, indirectly converted arc gate opening by piston displacement.This sensor body is arranged on arc door hydraulic jack
Above cylinder body, pulling out a seizing wire in sensor, one end of this steel wire rope pull-out is fixed on oil cylinder piston far-end with lock
Near door hinged place, along with extending and retracting of piston, steel wire rope is the most and then drawn out and regains, and steel wire rope pull-out relies on piston
Pull, regain the elastic force of scroll spring relying on sensor internal, this principle some to be similar to our energy used in everyday automatic
The ribbon regained.At sensor internal, steel wire disk is wound on a wheel hub, during steel wire rope pull-out, regaining, and wheel
Hub can and then rotate, and (past also commonly uses cheap incremental coding to be coaxially installed with an absolute type encoder with wheel hub
Device), this encoder in order to detect the angular displacement of wheel hub, this angular displacement signal typically by RS422 (SSI agreement) interface,
The agreements such as RS485(Modbus, Profibus) mode such as interface, 4-20mA electric current loop transmits to corresponding arc door electrical control cabinet
PLC(Programmable Logic Controller) or Measuring opening instrument, owing to the displacement at sensor inner wheel hub angle and the displacement of the lines of steel wire rope are
Linear corresponding relation, therefore can calculate displacement of the lines i.e. the position of oil cylinder piston of steel wire rope by simple linear transformation
Move, then indirectly calculated the aperture of gate by oil cylinder piston displacement.Though this technology uses universal, but shortcoming is obvious, mainly
Show: 1) storm flood season, gate upper pond level is higher, and all kinds of floating things such as some branches, tree root, weeds collect in lock
The edge of door upstream, often climbs over gate under the effect of wind or wave and directly pounds on following sensor steel wire rope, cause
Steel wire rope is pounded disconnected causes aperture measurement to lose efficacy, the foreign material that fall down in upstream or due to the too high floating foreign material come of the level of tail water
It is also possible to be wound around or hang steel wire rope causes extra disturbance on a steel cord, brings huge deviation to aperture measurement；
2) steel wire rope one encloses orderly being wrapped in above wheel hub during regaining, it sometimes appear that the situation of lap wound, so can
Cause the biggest measured deviation.3) scroll spring of sensor internal is of long duration may get rusty or mechanical failure, can cause
Steel wire rope can not be tightened very well or normally regain, even broken by oil cylinder piston.4) it is outdoor installation due to sensor, if anti-
It is bad that water does, and at heavy rain weather, rainwater is easy at the rotating shaft by sensor inner encoder enter decoder internal to be caused
Encoder damages.5) a piston displacement and gatage not simple mathematical relationship, is a more complicated functional relationships
System, the calculating of this function relates to mechanical dimension and the installation position data of many gates self, at the scene in actual application, especially
It is for the openness measuring device of later stage equipment, and these data are often difficult to accurately obtain, and this calculates to arc gate opening and brings very
The most difficult, in order to overcome this problem, mostly actual application being, the method matching taking aperture multidraw linear approximation is actual
Aperture function curve calculates aperture, but so not only has bigger calculating error, and debugs demarcation and bother very much, the most extremely
Needing to sample the aperture point of more than 10 less, each sample point is required for measuring actual aperture, as opening with additive method
The fixed basic data of scale is also required to ensure certain certainty of measurement.
2, for fluid pressure type gates of segmental shape, another conventional opening detection method is to measure oil cylinder piston displacement indirectly to change
Calculating aperture, only displacement transducer (such as: magnetostrictive displacement sensor) used is mounted in inside oil cylinder.Though this scheme
So there is no some shortcomings of above-mentioned draw-wire displacement sensor, but its shortcoming of yet having self: 1) due to displacement transducer built-in,
It is just internally installed in place at oil cylinder before oil cylinder dispatches from the factory that this is accomplished by displacement transducer, displacement transducer one during onsite application
Denier breaks down, keep in repair or change will and difficulty, the most even need to pull down whole oil cylinder depot repair, and keep in repair week
Phase length, cost are big.2) a piston displacement and gatage not simple mathematical relationship, is a more complicated functional relationships
System, the calculating of this function relates to mechanical dimension and the installation position data of many gates self, at the scene in actual application, especially
It is for the openness measuring device of later stage equipment, and these data are often difficult to accurately obtain, and this calculates to arc gate opening and brings very
The most difficult, in order to overcome this problem, mostly actual application being, the method matching taking aperture multidraw linear approximation is actual
Aperture function curve calculates aperture, but so not only has bigger calculating error, and debugs demarcation and bother very much, the most extremely
Needing to sample the aperture point of more than 10 less, each sample point is required for measuring actual aperture, as opening with additive method
The fixed basic data of scale is also required to ensure certain certainty of measurement.
3, for the aperture measurement of winding type gates of segmental shape, conventional scheme is to install with one heart with reel at the end face of reel
One absolute type encoder, measures the angular displacement of reel by this absolute type encoder, and angular displacement signal is typically connect by RS422
The mode such as mouthful (SSI agreement), RS485 interface agreements such as () Modbus, Profibus, 4-20mA electric current loop is transmitted to corresponding arc door
PLC in electrical control cabinet or Measuring opening instrument, reel angular displacement calculates into the line of hoisting rope by linear transformation
Displacement, then by the displacement of the lines conversion gatage of steel wire rope, owing to displacement of the lines and the gatage of steel wire rope are not the most letters
Single mathematical relationship, is a more complicated functional relationship, and the calculating of this function relates to the mechanical chi of many gates self
Very little and installation position data, at the scene in actual application, particularly with the openness measuring device of later stage equipment, these data are often
Being difficult to accurately obtain, this calculates to arc gate opening and brings a lot of difficulty, in order to overcome this problem, is mostly to take in actual application
The method matching actual aperture function curve of aperture multidraw linear approximation calculates aperture, but so not only has bigger meter
Calculating error, and debug demarcation and bother very much, the most at least need to sample the aperture point of more than 10, each sample point is required for
Measuring actual aperture with additive method, the basic data demarcated as aperture is also required to ensure certain certainty of measurement.
