Technical field

The present invention relates to a kind of level gauging, the tank gage is dedicated for measuring and show large-scale oil storage tank and similar containers Liquid level, the interface between liquid temperature and different liquids.

Background technique

After large-scale oil storage tank oil product passes in and out, disengaging oil product amount, the parameter that scene mainly obtains: oil storage are accurately calculated (density of oil product is usually into the oil product for having before tank third party to provide for the liquid level of tank, tank bottom water height and oil product temperature density It tests known to report)；The liquid level and other parameters of oil storage tank are obtained, mainly uses conventional pontoon steel band, magnetostriction, radar at present And servo liquid instrument；Traditional floating drum steel band tank gage, due to pulley, the frictional force of Pan Dan mechanism and mechanical counter is big, surveys Poor reliability is measured, precision is low；Magnetostrictive liquid level apparatus brings certain measurement error, range mistake because of test solution body temperature variable density It is high not easy to install, and float is easily blocked by conduit；Radar level gauge measures tank bottom oil-water interfaces difficulty, breaks down difficult, Using limited；Servo liquid instrument uses special-purpose member, and structure is complicated, and level gauging information is converted, amplification, multiple rings such as adjustment Section can be accepted by a computer utilization, and the reliability and precision of measured value are influenced in various degree.The scope of application is limited System, cost of investment are also high.

Oil storage tank pass in and out oil product trade settlement, measurement liquid level and tank bottom water height in terms of, Most current still with Subject to hand-dipping, by environment, the factors such as condition and operator's operative skill influence the precision of hand-dipping measurement, dislike Also jeopardize survey crew's safety when bad weather, and cannot accomplish real-time detection.

Summary of the invention

Tank gage of the present invention is that a fixed pulley, equal arc length in fixed pulley outer circle are fixedly mounted above oil storage tank tank deck side Several protrusion ball roller pins are embedded in, the steel band contacted is punched along y direction, in two adjacent pitch-rows and fixed pulley outer circle Two adjacent straight pin arc length are equal, and aperture is as straight pin outer diameter, steel band and floating drum top in oil storage tank on the right side of fixed pulley Connection, left side steel band are connect with the weight top in oil storage tank inner sleeve, and weight weight is greater than steel band weight, and floating drum is along conduit And dragline in oil storage tank liquid level go up and down and move up and down, under the action of weight and floating drum, steel band drive fixed pulley it is inverse or It rotates clockwise, fixed pulley makees pure rolling on steel band, and the millimeter dial and fixed pulley being mounted on fixed pulley are same with angle Direction rotates, and millimeter engraving is outside one's consideration the arc length that rotates through of circle and fixed pulley outer circle equal, the steel band amount of moving up and down that rotates through arc length As liquid level lifting amount in oil storage tank (setting steel band act on pulling force upward on floating drum constant always), then millimeter dial On scale variable quantity it is identical as liquid level changing value in oil storage tank, rice dial is to determine ratio through fixed pulley to be rotated in deceleration, When liquid level changing value is more than thousand millimeters in oil storage tank, rice dial shows the aggregate-value of liquid level rice in oil storage tank.In It measures in oil tank level lifting process, steel band is constantly to transfer at left and right sides of fixed pulley, since steel band has certain self weight, steel Band acts on pulling force upward on floating drum and is varied, and the error which generates measurement liquid level can be controlled in 2/10000ths Within；Since the error is linear, and can be completely eliminated with correction value.The bottom side of conduit installs direct-reading grease circle Face meter, height can show oil-water interfaces and its height depending on demand；Sleeve, installation on the inside of sleeve bottom are inserted into conduit Electronic eyes with illumination absorbs oil-water interfaces height and is transmitted to tank deck through cable；Multiple temperature are filled along outside of sleeve y direction Sensor is spent, quantity depends on the needs, and measurement data is transmitted to tank deck through cable；Casing can extract dimension from conduit at any time Shield.The tank gage energy real-time measurement shows the liquid level of oil storage tank, the oil temperature of tank bottom water height and different oil reservoirs；Measurement accuracy Height, measurement data is reliable and stable, and explosion-proof performance is good, and structure is simple, easy for installation, long service life；The resolution ratio that liquid level is shown Less than or equal to millimeter, system sensitivity is less than millimeter；The tank gage properties, index are superior to above-mentioned tank gage, also solve When oil storage tank disengaging oil product trade settlement hand-dipping, because of environment, the factors shadow such as condition and operator's operative skill Ring measurement accuracy, the problem that harsh weather cannot be detected in time.

Also the liquid level of scene display can be passed through electronic eyes from the water height of tank bottom and the oil temperature of different oil reservoirs through cable It is transmitted to control room to show, then after image recognition processing, calculates oil reserve in oil storage tank in real time on computers, be existing The automatic management of real oil storage tank tank field provides accurate and reliable data.

Detailed description of the invention

Attached drawing is schematic structural view of the invention.

The tank gage is by fixed pulley 1, millimeter dial 2, rice dial 3, weight 4, conduit 5, casing 6, direct-reading grease Level meters 7, electronic eyes 8, floating drum 9, temperature sensor 10, dragline 11 and steel band 12 form.

Specific embodiment

Below by structural schematic diagram, the course of work of the tank gage is described:

Oil tank level be in swept volume lowest order or and its when any of the above liquid level, buoyancy, steel of the floating drum 9 in oil product It is balanced under the action of the upward pulling force of band 12 and self gravity, in static state, manually dipping proofreads millimeter dial 2, rice at this time The show value of dial 3 and direct-reading oil-water interfaces meter 7.

When oil storage tank oil inlet liquid level rises, floating drum 9 is by the disturbance of oil product buoyancy, and Yuanping City weighs and is broken, and floating drum 9 is along conduit 5 and dragline 11 moved up with liquid level, steel band 12, to shifting on the left of fixed pulley 1, drives 1 He of fixed pulley under the action of weight 4 The synchronous rotary counterclockwise of millimeter engraving scale 2, millimeter engraving scale 2 shows liquid level millimeter variable quantity, when oil tank level height Variable quantity is more than thousand millimeters, and the aggregate-value of oil tank level height change rice is shown by rice dial 3；Oil storage tank oil inlet terminates Afterwards, floating drum 9 balances under the action of the buoyancy of oil product, the upward pulling force of steel band 12 and self gravity again, restores static, millimeter scale The liquid level of disk 2 and the combination display oil storage tank of rice dial 3；The oil temperature and tank bottom water height of different oil reservoirs are by temperature sensor 10 Intake output is measured to tank deck with electronic eyes 8.Conversely,.
