Abstract
The utility model relates to an electrode type liquid level detector which comprises a reversible motor, a steel wire rope, an inversion wheel, a probe and a heavy hammer. The utility model is characterized in that a reversible counter is also arranged above the inversion wheel. A transmission shaft is arranged in a bearing on the center of a casing, and a circular counting disk is arranged on the transmission shaft; blocking sheets are uniformly distributed around the circular counting disk, and correspond to photoelectric switches in the casing. The probe is one electrode, and tank liquid which is detected is another electrode. Due to the adoption of a test mode of electrode type momentary contact liquid and the reversible motor with high precision, the height of a liquid level is calculated by a photoelectric code reading device, and therefore, the utility model can carry out the measure of the liquid level with high precision in the environment of high alkali, serious scab and large liquid rolling wave.
Description
The utility model relates to a kind of detection liquid level technology, particularly a kind of electric pole type Level meter.
The surveying instrument that the technology of existing measuring liquid level has float-ball type, static pressure type etc. and liquid directly to contact when fluid to be measured is high-alkali, scabs when serious, and this instrument is operate as normal for a long time; Radar level gauge and ultrasonic level gage are a kind of measuring techniques that does not directly contact with liquid, still roll wave when big for liquid flow, and its measuring accuracy is lower.
The purpose of this utility model provides a kind of can scabbing seriously to high temperature, high-alkali, high burn into, and the liquid big liquid of wave that rolls carries out the electric pole type Level meter that high-precision liquid level is measured.
Task of the present utility model is to realize like this, it comprises reversible electric machine, wire rope, reversing roller, probe and weight, it is characterized in that: above reversing roller, also be provided with reversible register, its structure is to have a transmission shaft to place the bearing at housing center, and a circular numeration dish is arranged on the transmission shaft, and the optoelectronic switch in being evenly equipped with washer on dish week and being located at housing is corresponding, probe is an electrode, and tested tank liquor is another electrode.Be provided with limit switch between the reversing roller outside reversible register and detector shell, be connected with lead between the power supply of switch and reversible electric machine and the reversible register.
The utility model is owing to adopted the metering system of electric pole type moment contact liq, with employing high precision reversible electric machine electrode is carried out folding and unfolding, calculate liquid level by the photoelectricity code reader, therefore have high-alkali, scab seriously, and liquid rolls and carries out high-precision level gauging in the big environment of wave.
Fig. 1 is the structural representation of the utility model electric pole type Level meter.
Fig. 2 is the structural representation of reversible register of the present utility model.
The drawing explanation: 1. 13. optoelectronic switches are coiled in 12. numerations of probe 2. weights 3. reversing rollers 4. limit switches 5. reversible register standard wheels 6. reversing rollers 7. rope-winding wheels 8. solution tanks 9. instrument shells 10. bearings 11. transmission shafts
In conjunction with above accompanying drawing embodiment of the present utility model is elaborated.Be provided with reversible electric machine in the electric pole type Level meter housing 9, by reducing gear band one rope-winding wheel 7, one end of wire rope ties up on the rope-winding wheel 7, walking around reversing roller 6 then contacts with reversible register standard wheels 5 and limit switch 4, wire rope should have certain-length with contacting of reversible register standard wheels 5, to guarantee that wire rope does not slide on standard wheels.Wire rope hangs down in the solution tank 8 of instrument below after walking around the reversing roller 3 that is located at Instrument shell 9 places, and the end of wire rope is provided with a probe 1, and there is a weight 2 top of probe 1.The distance of 1 lifting of popping one's head in is read by reversible register, and reversible register is installed in the top of reversing roller 6.The structure of reversible register as shown in Figure 2, its transmission shaft 11 places the bearing 10 at Instrument shell 9 centers, and a circular numeration dish 12 is arranged on the transmission shaft 11, numeration dish dish be evenly equipped with washer on week and the optoelectronic switch 13 that is located in the housing 9 corresponding.Probe is an electrode, and tested tank liquor is another electrode.Be provided with limit switch between the reversing roller outside reversible register and detector shell, be connected with lead between the power supply of switch and reversible electric machine and the reversible register.When probe rises or descend, wire rope drives reversible register standard wheels 5, washer on the rotation numeration dish 12 produces photoimpact when passing through optoelectronic switch 13, the angle that the corresponding standard wheels 5 of photoimpact is rotated, the also just corresponding displacement of probe, the washer quantity on the numeration dish can require to determine according to measuring accuracy.According to the needs of measuring, can be set, the interval time of reversible electric machine work when probe 1 contact tank liquor, because probe is negative pole, tank liquor is anodal, so produce an electric signal, the counter-rotating of control reversible electric machine, make probe leave tank liquor, when being raised to the height of setting, the motor stall.Because repeated measurement, accumulated error in the system can surpass the requirement of measuring accuracy, is head it off, can between reversing roller above the probe and reversible register limit switch 4 be set, when needs carry out zero clearing, when reversible electric machine promotes probe, when weight is run into solution tank loam cake or other barrier, wire rope is produced resistance, so the wire rope tensioning presses down, make limit switch 4 instantaneous shutdown system power supplys, reversible electric machine stall, reversible register zero clearing.This detector can adopt computing machine to control, and realizes the robotization of measuring.
