Description
Technical field
The utility model relates to a kind of level monitoring device, is specifically related to a kind of to rocking the monitoring device that liquid is measured.
Background technology
In the prior art, existing level monitoring method has mechanical type, condenser type, pressure type, magnetic-type etc., and its measurement mechanism must be directly or relatively directly contacted with liquid level to be measured, thereby realizes the measurement for liquid level in the container.
But said method in all-vanadium flow battery is used, run into electrolytic solution blowback tank body after, liquid level rises and falls and causes float can bring measuring error with liquid fluctuating.All-vanadium flow battery, be will have a different valence state vanadium ion solution respectively as the active substance of anodal and negative pole, be stored in respectively in the electrolytic solution storage tank separately, battery is being filled, during discharge test, electrolytic solution is by the effect of pump, by cathode chamber and the anode chamber of outside receiver difference circular flow through battery, and in electrode surface generation oxidation and reduction reaction, realization discharges and recharges battery, in order to guarantee the operate as normal of battery system, need the anodal and negative pole electrolytic solution of the monitoring in real time height of liquid level in the receiver separately, because redox reaction has taken place through the cathode chamber of battery and the electrolytic solution after the anode chamber in circular flow, vanadium ion concentration changes, in order to guarantee that vanadium ion concentration is even in the receiver, electrolytic solution need pour with certain flow velocity in the receiver, and this just causes liquid level to fluctuate, and the measuring accuracy error was bigger when use had level monitoring device now.
The utility model content
When measuring liquid level for solving in the prior art, because slosh can't obtain the problem of accurate measurement result, the utility model provides a kind of can accurately measure the measurement mechanism that rocks liquid level.Concrete scheme is as follows: a kind of fluctuation level monitoring device, comprise pulley blocks, floating ball device and display device, and it is characterized in that described floating ball device is three ball floats that connected by connecting rod.
Another optimal way of the present utility model: described pulley blocks comprises travelling block, quiet pulley A, quiet pulley B and pulley bracket A, pulley bracket B and pulley bracket C, quiet pulley A, quiet pulley B are fixed by the isometric backguy on pulley bracket B, the pulley bracket C, described travelling block is connected by the mid point of backguy with three floating ball rods, walks around travelling block, quiet pulley A and quiet pulley B access display device respectively by the measurement backguy that pulley bracket A draws.
Another optimal way of the present utility model: described display device comprises measuring tube, sash weight and scale, and described sash weight is installed in the measuring tube and with the measurement backguy of pulley blocks and is connected, and described scale is installed in the interior measurement wiring of measuring tube.
Another optimal way of the present utility model: described length of connecting rod equates.
Another optimal way of the present utility model: described three ball floats in a plane and between angle equate.
Another optimal way of the present utility model: described measuring tube outside is equipped with the reading window.
The utility model adopts three ball floats to measure liquid level and makes its measurement range expand planar survey to from a pageview, changed traditional measurement method, and pulley blocks measurement by magnification value can effectively improve measuring accuracy, rational in infrastructure, safe in utilization, dependable performance, easy maintenance is installed easily.
Description of drawings
Fig. 1 the utility model structural representation
Fig. 2 the utility model ball float structural representation
Among the figure: 1, ball float 2, travelling block 3, quiet pulley A 4, quiet pulley B 5, measuring tube 6, sash weight 7, measurement backguy 8, reading window 9, pulley bracket A 10, pulley bracket B 11, pulley bracket C12, connecting rod 13, mid point 14, scale
Embodiment
As shown in Figure 1, this programme monitoring device comprises pulley blocks, floating ball device and display device, pulley blocks comprises quiet pulley A3, quiet pulley B4, travelling block 2 and pulley bracket A9, pulley bracket B10 and pulley bracket C11, measurement mechanism comprises ball float 1, connecting rod 12, and display device comprises reading window 8, scale 14, measuring tube 5 and sash weight 6.
Above the receiving fluids storage tank, pulley bracket A9 and pulley bracket B10 are installed, in the storage tank outside pulley bracket C11 is installed, three ball floats 1 form a triangulation face in the mode of isogonism, utilize the connecting rod 12 of equal in length to connect between each ball float, travelling block 2 is installed above the mid point 13 that three ball floats connect, quiet pulley A3 is installed in travelling block 2 tops, quiet pulley B4 is installed in the storage tank outside parallel with quiet pulley A3, a hollow measuring tube 5 is installed below quiet pulley B, wherein quiet pulley A and quiet pulley B utilize and hang over pulley bracket B10, pulley bracket C11 goes up isometric backguy and hangs, travelling block is walked around in the measurement backguy 7 that the pulley bracket A9 of travelling block top draws, pass quiet pulley A again, quiet pulley B, measure the backguy line end and tangle a sash weight 6, sash weight 6 is positioned at measures tube 5, and reading window 8 is installed on the measuring tube outside surface, above sash weight, measure and measure scale 14 of connection in the wiring in the tube, have a backguy to be connected on the travelling block axle center with the mid point of three ball floats.
In use, ball float is placed on the testing liquid, ball float can be along with the fluctuation of liquid dipping and heaving, because three ball floats adopt the isogonism mode to arrange in one plane, therefore always there is the fluctuating height of one or two ball float inconsistent with other the floating height of two or one ball floats, because three ball float structures make the mid point flying height only be 1/3 of ball float flying height, the fluctuating height change of its three ball float tie points passes to travelling block, the sash weight that is arranged in measuring tube is by measuring the variation that travelling block is sensed in backguy, will rise accordingly or descend, according to the knee-action of scale in measuring tube, numerical value is reflected on measuring tube measures above the reading window, obtain the numerical value that needs.This programme is equivalent to amplify measured value with mechanical means because ball float connects the operating distance that the knee-action distance of mid point equals 1/2nd scales, makes measuring accuracy improve 2 times.
The selection of various materials adapts to the liquid phase that needs test in this programme, during as the test corrosive liquid, needs ball float, connecting rod all anticorrosive.
