Abstract
The utility model provides a storage tank liquid level measurement device, comprises probe 1, span wire 2, upper limit switch 3, spring 4, count probe 5, branch 6, unsteady runner 7, position switch 8, cylinder 9, motor 10, screw rod 11, the utility model discloses owing to adopt the probe to walk around unsteady runner through the span wire and be connected with the cylinder, be connected respectively through branch and count probe, upper limit switch, spring, position switch on unsteady runner, the cylinder passes through the screw rod and is connected with the motor. When the probe touches the liquid level, the tension of the suspension cable is reduced, the spring lifts the floating rotating wheel of the suspension probe, the control switch is driven to stop the rotation of the motor, and an indication is given. The motor is reversely rotated, the probe is withdrawn, the grating disk on the floating rotating wheel and the infrared transmitting and receiving devices on the two sides form a counting sensor, and the control display device processes signals sent by the counting sensor and converts the signals into measuring results. Simple structure, easy operation and is very suitable for field application.
Description
Technical field:
The utility model relates to a kind of measurement of liquid level in the storage tank in Petroleum Production, particularly a kind of tank level measurement mechanism.
Background technology:
In Petroleum Production, need a large amount of storage tank, and the measurement of liquid level in the storage tank is crucial, concerns the safety of field produces and the accurate metering of crude oil.The measurement of liquid level in the past is to utilize the principle of ultrasonic reflections to measure, the problem that this method exists is that oil tank liquid level top is a uneven coagulate solids piece surface, ripple is produced the scattering of different directions, bring measuring error, force instrument to strengthen emissive power, the production difficulty of instrument and cost height, the instrument price is expensive, can't apply.Traditional for another example float level meter, its float and evener couple together with silk, line, drive pulley by silk thread during liquid level change and rotate liquid level position as can be known, this method has following deficiency: float contacts with liquid level all the time, silk, line are exposed all the time, be subjected to environment (freeze, volatile matter condense, corroded etc.) influence big, poor stability as liquid level.So, on-the-spot at present still based on artificial upward jar manual metering of tape measure of using the band "painted-face" character in opera, but the artificial observation error is bigger, and go up a jar operation every day for several times, and very there is potential safety hazard in inconvenience.
The utility model content:
The purpose of this utility model is to provide a kind of tank level measurement mechanism, adopts far-end control to measure, and is implemented in the liquid level that directly obtains storage tank on ground or the other-end, and is low-cost, precision is high, safe and reliable.
The utility model is to realize like this, it is made up of probe (1), suspension cable (2), upper limit switch (3), spring (4), counting probe (5), pole (6), the runner (7) that floats, position switch (8), cylinder (9), motor (10), screw rod (11), probe (1) is walked around unsteady runner (7) by suspension cable (2) and is connected with cylinder (9), upward be connected respectively by pole (6) and counting probe (5), upper limit switch (3), spring (4), position switch (8) at unsteady runner (7), cylinder (9) is connected with motor (10) by screw rod (11).
Its principle of work is:
During measuring liquid level, the control display device links to each other with interface, connects and transfers switch, motor just changes, and cylinder just changes, and probe descends, when probe touches liquid level, unsteady runner is reduced by pulling force, and generation is floated under the effect of spring, drives position switch and disconnects, make motor, cylinder stall, probe remains on liquid level position, and the liquid level warning light is switched on, and finishes detecting liquid level.
Connect measuring switch, the motor counter-rotating, the cylinder counter-rotating, suspension cable traction probe rises, and the runner that floats drives grating and rotates, and the sensor for countering displacement signal sends to the control display device and handles, and shows the probe shift value.When probe rises to upper limit switch place, switch motion, motor stops traction, and warning light is bright, finishes measurement.
The utility model is owing to adopt probe to walk around the runner that floats by suspension cable to be connected with cylinder, on unsteady runner by pole with count probe, upper limit switch, spring, position switch and be connected respectively, cylinder is connected with motor by screw rod.Motor is walked around moving, and suspension cable is transferred, and when probe touches liquid level, suspension cable is reduced by pulling force, and spring lifts the unsteady runner of suspention probe, drives gauge tap and stops the rotation of motor, and provide indication.Make the motor counter-rotating, regain probe, grating dish on the runner that floats and both sides infrared, receiving trap constitute sensor for countering, and the control display device is handled the signal that sensor for countering sends, and converts measurement result to.Simple in structure, processing ease is well suited for rig-site utilization.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of probe 1, suspension cable 2, upper limit switch 3, spring 4, counting probe 5, pole 6, the runner 7 that floats, position switch 8, cylinder 9, motor 10, screw rod 11, probe 1 is walked around the runner 7 that floats by suspension cable 2 and is connected with cylinder 9, be connected respectively with counting probe 5, upper limit switch 3, spring 4, position switch 8 by pole 6 on unsteady runner 7, cylinder 9 is connected with motor 10 by screw rod 11.Probe is not with level change, and the axle of the runner that floats links by support and spring; Supporting shaft support and switch links; Float runner with constitute sensor for countering by grating dish and ultrared emission, receiving end and link.
1. measurement mechanism is simple in structure, low cost of manufacture; Discrete design, intercommunity is good, and one Individual control display device can cooperate a plurality of measurement mechanisms to use, and overall cost is low.
2. the precision height is digital the demonstration, accurate than the artificial observation data.
3. measure with the discontinuous way of contact, reduce environment to the impact of suspension cable and probe, steady Qualitative height.
4. avoid manually going up the inconvenience that tank is measured, realize easily teletransmission.
Claims (1)
1. tank level measurement mechanism, form by probe (1), suspension cable (2), upper limit switch (3), spring (4), counting probe (5), pole (6), the runner (7) that floats, position switch (8), cylinder (9), motor (10), screw rod (11), it is characterized in that: probe (1) is walked around unsteady runner (7) by suspension cable (2) and is connected with cylinder (9), upward be connected respectively by pole (6) and counting probe (5), upper limit switch (3), spring (4), position switch (8) at unsteady runner (7), cylinder (9) is connected with motor (10) by screw rod (11).
