Abstract
The utility model relates to a container liquid detecting device which provides a bobber electric potential type liquid level measurement device. The device is characterized in that: a bracket is arranged on the container, and a counterbalance body and a bobber are arranged in the liquid respectively at the two sides of the rotation pulley of the bracket. When the bobber descends (or ascends) with the liquid level, the interaction of the bobber, the counterbalance body, and the buoyancy lead the bobber to descend or ascend so that the pulley rotates under a tangential force to drive the rotation of the potentiometer shaft on the bracket and thus potential amount change is generated, and the reading is performed through a mimic digital meter. The method of measuring container liquid depth through changing of the liquid level has simple structure, and is easy to operate, with low cost and high measurement precision.
Description
(1) technical field:
The utility model relates to a kind of liquid in container sounding gear.
(2) background technology:
The widely used oil vessels of industrial and mining enterprises (being commonly called as oily tank) often need to understand or measure its trapped fuel degree of depth, so that in time add at present.Usually the method that adopts is tape measure or ultrasound wave depth calibrator.Must be by manually carrying out with the tape measure method, measurement result is by the range estimation reflection, and error is big, wastes time and energy; Use ultra-sonic depth finder, the use cost height, mechanism's more complicated is used inconvenient.
(3) summary of the invention:
The utility model provides a kind of float current potential formula liquid surface measuring device, utilization is positioned over float and the balance weight body in the oil vessel, when liquid levels changes, float is under the effect of buoyancy and balance weight body, to produce the displacement of vertical direction, and rotate and convert analog digital meter reading to, just can record the variable quantity of liquid level position by pulley belt moving-wire potentiometer shaft, according to the liquid level position variable quantity, just can calculate the degree of depth of liquid in container.The load that this device has guaranteed to act on the linear potentiometer axle makes it stability of rotation for minimum, potential change accuracy of measurement height, and numeral meter reading is accurate.
The utility model is to realize like this, a kind of float current potential formula liquid surface measuring device, pulley and bonnet are connected as one, can freely rotate on support by Bearing Installation, linear potentiometer is fixed on the support, the rotation axis two ends are fixedly connected with potentiometer shaft and bonnet respectively, have vertical channel and flat spin groove on the pulley, the counterweight rope is installed in the vertical channel, and corkline is installed on the flat spin groove, counterweight rope one end is fixed on the pulley, one end and balance weight body link, and corkline one end is fixed on the pulley, and an end and float link, balance weight body and float overhang respectively on the cylindrical of pulley both sides, and balance weight body and float all place liquid in container.
Above-mentioned float current potential formula liquid surface measuring device, transmission shaft can be a sectional type universal coupling structure.
When the liquid level of liquid in container is constant, float deadweight and buoyancy make a concerted effort and balance weight body is conducted oneself with dignity and the balance of making a concerted effort to keep of buoyancy.When liquid level reduces, float buoyancy will reduce, this moment, float and balance weight body were sunk out of trim, till when reaching with the new equilibrium state of balance weight body, to the tangential force of pulley output pulley is rotated by corkline because float sinks, drive potentiometer shaft by bonnet and intermediate shaft and rotate synchronously, the linear potentiometer current potential is changed, and be converted to the reading of the analog digital meter that connects with potentiometer, thereby draw the level change amount.
(4) description of drawings:
Fig. 1 is a float current potential formula liquid surface measuring device synoptic diagram.
Among the figure, 1 is the analog digital meter, and 2 is linear potentiometer, 3 is support, and 4 is potentiometer shaft, and 5 is vertical channel, 6 is the counterweight rope, and 7 is pulley, and 8 is corkline, 9 is the flat spin groove, and 10 is bearing, and 11 is bonnet, 12 is stop screw, and 13 is transmission shaft, and 14 is locking plate, 15 is balance weight body, and 16 is float, and 17 is container.
(5) embodiment:
Optimal way of the present utility model is provided by following accompanying drawing.
Referring to Fig. 1, linear potentiometer 2 is fixed on the support 3, and link with secondary instrument analog digital meter 1, support 3 is fixed on the container 17, pulley 7 is connected as one with bonnet 11, be installed on the support 3 by bearing 10, be positioned at support 3 centers transmission shaft 13 two ends respectively with potentiometer shaft 4 and bonnet 11, be fixedly connected with stop screw 12, bearing 10 outsides are equipped with locking plate 14, have vertical channel 5 and flat spin groove 9 on the pulley 7, corkline 8 is positioned on the flat spin groove 9, one end is fixed on the pulley 7, one end connects with float 16, counterweight rope 6 is positioned on the vertical channel 5, one end is fixed on the pulley 7, one end connects with balance weight body 15, balance weight body 15 and float 16 all place liquid in the container 17, float 16 and balance weight body 15 place the both sides cylindrical of pulley 7 respectively, when liquid level in the container 17 reduces, the deadweight P2 of float 16 and buoyancy Q2 make a concerted effort, greater than the deadweight P1 of balance weight body 15 and making a concerted effort of buoyancy Q1, the displacement vertically downward of float 16 this moment, the tangential force that is produced by corkline 8 is rotated the pulley 7 that is installed on the support 3, because the load that acts on linear potentiometer axle 4 for minimum, rotates just very steady so drive potentiometer shaft 4 synchronously, linear potentiometer 2 produces the variation precision height of current potentials, this moment by read on the secondary instrument analog digital meter 1 reading accurate.When the linear potentiometer model is the WX5-11 type, balance weight body 15 is 700 grammes per square metre copper rods, float 16 is that 1000 grammes per square metres are made of copper, the bottom is cone, top is cylindrical sealing thin-walled ducted body, corkline 8 and counterweight rope 6 are 2 millimeters stainless steel wires of Φ, flat spin groove center diameter on the pulley 7 is 67 millimeters of Φ, corkline 8 is totally 10 circles, when counterweight rope 6 and corkline 8 are isometric, can record 2 meters of level change amount L=10 π D ≈.If container 17 is uniform cross section (or regular) shape, then can calculate liquid container by the level change amount.
The utility model is simple in structure, and is easy to operate, and low cost of manufacture is measured accurately.
