(3) settle blow vent, filtering screen on the bottom mouthpiece cover of testing tube at the upper pipes port part of testing tube, and the support of reservoir level sensing device is installed on bulwark;
(4) after settling reservoir level sensing device on support, stay cord is drawn from the rope drum of electric block, through rope winding jib, be wound around wiring dish two to enclose, through the pulley of pulley microswitch, pass the through hole of base and rope mouth, stay cord is tied up on float, then float is put into testing tube from the testing tube upper end mouth of pipe;
(5) after the cable of magnetosensitive limit switch A, magnetosensitive positioning switch, magnetosensitive limit switch B, pulley microswitch, wiring formula level sensor, electric block being connected with hydroenergy storage station reservoir level tester, operate this reservoir level tester, open the motor of electric block, rotate rope drum, lifting float etc. carries out just debugging; After starting retaining until reservoir, discharging water, then operate hydroenergy storage station reservoir level tester and debug further;
(6) arrangement of whole hydroenergy storage station reservoir level tester is completed.
The principle of work of hydroenergy storage station reservoir level tester of the present invention: by being arranged on the testing tube on rock upstream dam slope faceplate panels, utilize the float in testing tube pipe, by stay cord, the change in location of float is passed to reservoir level sensing device, carry out the test of hydroenergy storage station reservoir level.Owing to communicating with air in testing tube, reservoir flushes all the time with the water level in testing tube, so the water level in 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 float, respectively by the control signal of magnetosensitive limit switch B, magnetosensitive positioning switch, magnetosensitive limit switch A output equivalent water level.
The principle of work of reservoir level sensing device: the stay cord tying up to float in testing tube, enters from the rope mouth of reservoir level sensing device, through the pulley of pulley microswitch, is wound around wiring dish two weeks, then through after thread arranging device, coils the rope drum in electric block.When reservoir level rises or decline, the float in testing tube also rises thereupon or declines, and ties up to the stay cord on float, with water level decreasing, and float loss of buoyance, make the pulling force of stay cord become large, stay cord is then tight; Rise with water level, float obtains buoyancy, and stay cord pulling force is diminished, and stay cord then relaxes.Now the pulley of pulley microswitch is vertically tight against on stay cord, the large young pathbreaker of stay cord pulling force triggers pulley microswitch.The pulley yoke frame body activity of this pulley microswitch is placed in switch base, can move by one-dimensional square, be equivalent to hilted broadsword double-gate switch to micro-back and forth.When the water surface transfixion of float in testing tube, buoyant effect, the weight of float is G, the pulling force tying up to stay cord on float is N, i.e. N=G, and the pulley yoke that 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 the water level descends, float loss of buoyance, tie up to the pulling force of stay cord on float and add greatly G+F, tight stay cord is the bottom in pulley yoke frame body press-in switch base, and switch is the unlatching of state 2, the rope of electric block drum is allowed to rotate clockwise to loosen stay cord, arrive at after the water surface until float, float recovers buoyancy, and the pulling force tying up to stay cord on float is N, the centre of wheel carrier frame body snap-switch seat, switch returns to form 1; When water level rises, float floats, tie up to the pulling force of stay cord on float and be reduced to N-F, lax stay cord by pulley yoke frame body bullet to the top in switch base, switch is the unlatching of state 3, and the rope of electric block drum rotates counterclockwise to tighten up stay cord thereupon, when tying up to that on float, the pulling force of stay cord reaches N, the centre of pulley yoke frame body snap-switch seat, switch returns to form 1.Like this, no matter fluctuation in stage, float rests on the water surface in testing tube automatically.When to only have pulley microswitch to be in switch be state 1, pulley microswitch sends the signal of wiring formula level sensor water level reading to reservoir level tester.The wiring dish of design setting diameter is had again to be fixed on the main shaft of wiring formula level sensor, stay cord takes up two circles on wire spool, and be pressed on the stay cord of wiring dish by press rope wheel elasticity, do not unclamp when not allowing stay cord walk or skid in wiring dish, stay cord is made synchronously to drive the main axis of wiring formula level sensor, exported travel distance and the direction of stay cord by wiring formula level sensor, thus obtain reservoir level transducing signal.
The principle of work of wiring formula level sensor: the main axis of wiring formula level sensor is moved in wiring dribbling, then by spindle transmission gear group, the switching of minimum for gear set engaged wheel wheel is accelerated to rotate.Wiring dish rotates a circle, switches wheel and will rotate up to ten thousand times, improve measuring resolution like this.The number of times of the magnetic line of force of magneto sensor A, magneto sensor B is switched with the magnet circle switched on wheel, obtain the transducing signal of reservoir level height, switch the precedence of magneto sensor A, magneto sensor B with the magnetic line of force of this magnet circle, obtain the transducing signal in reservoir level lifting direction.The transducing signal in height of water level, lifting direction, through the identification of reservoir level tester, process, counting, storage, 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 that the present invention proposes and allocation method thereof, it can meet, and hydroenergy storage station reservoir level heave amplitude is large, SEA LEVEL VARIATION speed is fast, measuring accuracy is high, and on dam slope inclined-plane, test the requirement of water level, have round-the-clock, wide range, high precision, fast, volume little, reliable operation, feature easy for installation, be a kind of instrument that can export hydroenergy storage station reservoir level in real time.
