A kind of allocation method of hydroenergy storage station reservoir level tester carries out successively according to the following steps,
(1) on the panel of hydroenergy storage station reservoir face dam upstream dam slope, behind vertical equidistant arrangement one row's buttress, limit interoperability test tube coupling, the vertical axis of dam in limit is installed on testing tube on those buttresses;
(2) perforate on the testing tube upstream side tube wall at peak level, ordinary water level, level of dead water place, settle magnetosensitive limit switch A, magnetosensitive positioning switch, magnetosensitive limit switch B respectively, its cable is penetrated the cable tube of being close to testing tube, introduce in the reservoir level sensing device at dam crest position;
(3) settle blow vent in the upper pipes oral area position of testing tube, filtering screen on the mouthpiece cover of the bottom of testing tube, and the support that the reservoir level sensing device is installed at bulwark;
(4) after support is settled the reservoir level sensing device, draw stay cord from the rope drum of electric block, pass rope winding jib, twine wiring dish two circles, pulley through the pulley microswitch, pass the through hole and rope mouth of base, stay cord is tied up on the float, again float is put into testing tube from the testing tube upper end mouth of pipe;
(5) the cable of magnetosensitive limit switch A, magnetosensitive positioning switch, magnetosensitive limit switch B, pulley microswitch, wiring formula level sensor, electric block with after hydroenergy storage station reservoir level tester is connected, operate this reservoir level tester, open the motor of electric block, rotate the rope drum, lifting float etc. carries out debugging just; After treating that reservoir begins retaining, discharges water, operate hydroenergy storage station reservoir level tester again and further debug;
(6) finish the arrangement of whole hydroenergy storage station reservoir level tester.
The principle of work of hydroenergy storage station reservoir level tester of the present invention: by being installed in the testing tube on the rock upstream dam slope faceplate panels, utilize the float in the testing tube pipe, by stay cord the change in location of float is passed to the reservoir level sensing device, carry out the test of hydroenergy storage station reservoir level.Owing to communicate with atmosphere in the testing tube, the interior water level of reservoir and testing tube flushes all the time, so the interior water level of testing tube can represent the water level of reservoir.When reservoir level arrives level of dead water, normal pool level, peak level, under the effect of the magnet strip magnetic force in the float, exported the control signal of equivalent water level respectively by magnetosensitive limit switch B, magnetosensitive positioning switch, magnetosensitive limit switch A.
The principle of work of reservoir level sensing device: tie up to the stay cord of float in the testing tube, enter from the rope mouth of reservoir level sensing device, through the pulley of pulley microswitch, twine wiring two weeks of dish, pass thread arranging device again after, coil the rope drum in electric block.When reservoir level rose or descend, the float in the testing tube also rose thereupon or descends, and ties up to the stay cord on the float, descended with water level, and the float loss of buoyance makes the pulling force of stay cord become big, and stay cord is then tight; Rise with water level, float obtains buoyancy, and the stay cord pulling force is diminished, and stay cord is then lax.Now the pulley of pulley microswitch vertically is tight against on stay cord, the big young pathbreaker of stay cord pulling force triggers the pulley microswitch.The pulley yoke frame body activity of this pulley microswitch is placed in the switch base, and trace is mobile back and forth for energy one dimension direction, is equivalent to hilted broadsword double-gate switch.When the water surface transfixion of float in testing tube, buoyant effect, the weight of float is G, the pulling force that ties up to stay cord on the float is N, i.e. N=G, and the pulley yoke that the pulley microswitch is sliding rests on the centre of switch base, switch is state 1, and the rope drum of electric block stops operating; When water level descends, the float loss of buoyance, tie up to that the pulling force of stay cord adds greatly G+F on the float, tight stay cord is pressed into bottom in the switch base to pulley yoke frame body, and switch is the unlatching of state 2, allow the rope drum of electric block clockwise rotate to loosen stay cord, after treating that float arrives at the water surface, float recovers buoyancy, and the pulling force that ties up to stay cord on the float is N, the rebound centre of switch base of wheel carrier frame body, switch returns to form 1; When water level rises, the float come-up, tie up to that the pulling force of stay cord is reduced to N-F on the float, lax stay cord is by the top of pulley yoke frame body bullet to the switch base, switch is the unlatching of state 3, and the rope drum of electric block rotates counterclockwise to tighten up stay cord thereupon, ties up to when the pulling force of stay cord reaches N on the float, the rebound centre of switch base of pulley yoke frame body, switch returns to form 1.Like this, no matter fluctuation in stage, float rests on the water surface in the testing tube automatically.When having only the pulley microswitch to be in switch to be state 1, the pulley microswitch sends the signal of wiring formula level sensor water level reading to the reservoir level tester.There is the wiring dish of design setting diameter to be fixed in the main shaft of wiring formula level sensor again, stay cord takes up two circles at wire spool, and be pressed on by press rope wheel elasticity on the stay cord of wiring dish, do not allow the stay cord walking time not unclamp or skid in the wiring dish, the main shaft that makes stay cord drive wiring formula level sensor synchronously rotates, by travel distance and the direction of wiring formula level sensor output stay cord, thereby obtain the reservoir level transducing signal.
The principle of work of wiring formula level sensor: the main shaft of the moving wiring formula level sensor of wiring dribbling rotates, and again by the spindle transmission gear group, the switching wheel acceleration of the minimum engaged wheel of gear set is rotated.The wiring dish rotates a circle, switches wheel and will rotate up to ten thousand times, has improved measuring resolution like this.Switch the number of times of the magnetic line of force of magneto sensor A, magneto sensor B with the magnet circle on the switching wheel, obtain the transducing signal of reservoir level height, with the magnetic line of force switching magneto sensor A of this magnet circle, the precedence of magneto sensor B, obtain the transducing signal of reservoir level lifting direction.The transducing signal of height of water level, lifting direction through identification, processing, counting, the storage of reservoir level tester, demonstrates the water level of hydroenergy storage station reservoir.
Compared with the prior art, beneficial effect of the present invention is embodied in: a kind of hydroenergy storage station reservoir level tester and allocation method thereof that the present invention proposes, it can satisfy, and hydroenergy storage station reservoir level heave amplitude is big, SEA LEVEL VARIATION speed is fast, measuring accuracy is high, and the requirement of testing water level on the dam slope inclined-plane, have round-the-clock, wide range, high precision, fast, little, the reliable operation of volume, characteristics easy for installation, be a kind of instrument that can export the hydroenergy storage station reservoir level in real time.
