Abstract
The utility model relates to an automatic measuring instrument which can measure the sediment concentration in water on the spot in hydrometry and is mainly composed of a low-voltage power supply, a single chip computer, a probe, a PP40 printer and a print power supply. The automatic measuring instrument can measure the sediment concentration which is less than 2 kg/m<3>on the spot and can discretionally measure in the water whose depth is scores of meters. Control measurement and the value of the sediment concentration which is printed by the printer are implemented by the single chip computer to realize the automation of the hydrometry. The utility model is maximally characterized in that the real-time measurement can be carried out on the spot and the measuring error is less than those of native and foreign instruments of the same kind.
Description
The utility model relates in a kind of hydrologic survey the automatic measuring instrument of silt content in the measure field water.
Traditional sampling weight method is still continued to use in the measurement of silt content in the hydrologic survey at present.After water sample is gathered at the scene, utilize the oven dry weighing method to draw silt content.Test is too complicated in this way, time-consuming take a lot of work expensive.
The purpose of this utility model is exactly to be to adopt a kind of automatic sand meter that can measure silt content in the water at the scene in real time.
The purpose of this utility model is achieved in that
Structure of the present utility model is by low-tension supply 1, and single-chip microcomputer 3 pops one's head in 2, PP40 printer 4, and printer power supply 5 is formed.Wherein pop one's head in 2 structure by probe cover 6, pad 7, system water rubber 8, sonde body 9 is formed.Be provided with infrared light supply 12 in the sonde body 9, tested part 13, detector 4.Tested part 13 constitutes a rectangular parallelepiped by organic glass, is fixed in the groove of sonde body 9 front ends, and one semi-hermetic and standard water 10 is housed, second half communicates with the external world, is the tested Sha Shui 11 that contains.
Advantage of the present utility model is:
Adopt the utility model field survey 2kg/m at the scene
3Following silt content.It can be measured arbitrarily in tens meters depth of waters, implements control survey, the value of printer prints silt content by single-chip microcomputer.Realized the robotization of hydrologic survey, its error is less than same quasi-instrument both domestic and external.
Fig. 1 is a fundamental diagram of the present utility model.
Fig. 2 is the double light path principle schematic of the said probe of the utility model.
Fig. 3 is the structural representation of the said probe of the utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
The utility model is to adopt sand meter probe double light path principle shown in Figure 2, utilizes the low-tension supply 1 of probe shown in Figure 32 in conjunction with sand meter shown in Figure 1, single-chip microcomputer 3, and PP40 printer 4, printer power supply 5 is finished the measurement to silt content in the hydrologic survey.
As shown in Figure 1, low-tension supply 1, probe 2, single-chip microcomputer 3, PP40 printer 4 is connected by lead between the printer power supply 5.As shown in Figure 2, the probe double light path principle schematic of sand meter is divided infrared light source 12, tested part 13, detector 14 3 parts, by organic glass standard water 10 and the tested Sha Shui 11 that contains is separated in the tested part 13.When detecting, probe 2 measured layers that are placed in the water, the electric energy that low-tension supply 1 produces is given infrared light supply 12 by cable transmission, the light that sends from infrared light supply 12 is divided into two bundles, a branch of by standard water 10, a branch of by containing Sha Shui 11, accept by detector 14 from the two-beam that these two kinds of water bodys transmit, and be converted into two groups and output signal to single-chip microcomputer 3, single-chip microcomputer 3 softwares according to the establishment of youth's primary-Beer law are handled data automatically, and its result transmission prints the relevant data of actual measurement silt content to printer 4.As shown in Figure 3, probe is made up of probe cover 6, pad 7, system water rubber 8, sonde body 9.Adopt between probe cover 6 and the sonde body 9 to be threaded, pad 7 and system water rubber 8 are contained between them.Wherein probe cover 6, pad 7, and the center of system water rubber 8 has a circular hole to communicate, and cable is connected low-tension supply 1 and single-chip microcomputer 3 by this hole with infrared light supply 12 and detector 14 in the sonde body 9.The utility model can directly descend water gaging, as long as the cable long enough can be measured the silt content in the water in real time in any depth of water.
