Abstract
A dynamic detection device for silt content in runoff comprises a single chip computer. The lower part of a drainage tube for leading the runoff water extends into an overflowing machine; the bottom of side of the overflowing machine is fixed with a solenoid valve for draining water; a liquid level switch is arranged on the inner wall surface of the overflowing machine at a certain height; and thewhole overflowing machine is laid on a weighting sensor. The dynamic detection device for silt content in runoff is featured with simple structure, convenient and fast operation maintenance, capableof detecting the slit content in the runoff quickly and improving the detection efficiency and accuracy.
Description
Technical field
The utility model technology relates to a kind of water flow mud-sand content testing device, particularly at the field irrigation and the escape canal of low water head, certain flow, and in the detection of district observation field, sediment charge in the runoff is carried out the device of in good time detection of dynamic.
Background technology
In the open-air test item of departments such as irrigation and water conservancy, forest ecology, environmental protection, radial flow sediment content is an important index.
Conventional classical direct assay method has: 1, oven drying method: artificial field sampling, then indoor to operations such as sample liquid filter, dries, weighs, determine the sediment charge of sample liquid; 2, hydrometer method: artificial field sampling, measure proportion again and then infer the sediment charge of sampling flowing water.Indirect determination method has laser method branch, gamma-rays method, supercritical ultrasonics technology spectrophotometric method, infra-red method, vibratory drilling method and capacitance method.
The subject matter that exists is: 1, classical way, and poor in timeliness, operation is many, from sampling testing result, often needs a few days; 2, indirect method, the content range of monitoring often has certain limitation, and accuracy is not fine, and it is higher to detect cost.
The utility model content
The purpose of the utility model technology provides a kind of simple in structure, operates, safeguards dynamic detection device of runoff sediment content easily.
The purpose of the utility model technology is achieved in that a kind of dynamic detection device of runoff sediment content, comprise single-chip microcomputer, LOAD CELLS, overflowing device is stretched in the drainage tube bottom that is used for introducing runoff water, the overflowing device side bottom is mounted with a solenoid valve (model: model004 that is used for drain water, the place of production, the U.S.), level switch is arranged on the overflowing device internal face certain altitude, and whole overflowing device is flat on the described LOAD CELLS.
This novel beneficial effect is: introduce the overflowing device of this device when the flowing water of small stream ditch or open channel after, can fast detecting go out its sediment charge in process of flowing, the ageing and accuracy that raising detects reduces the energy consumption and detection cost that detect.
Description of drawings
Fig. 1 is the structural representation of the utility model pick-up unit.
Embodiment
Fig. 1 illustrates, and forms automatic control unit by single-chip microcomputer.Silt content dynamic detection device is made up of drainage tube 1, overflowing device 2, level switch 3, solenoid valve 4, LOAD CELLS 5.Overflowing device 2 is stretched in drainage tube 1 bottom that is used for introducing runoff water, the overflowing device side bottom is mounted with a solenoid valve 4 that is used for drain water, level switch 3 is arranged on the overflowing device 2 internal face certain altitudes, and whole overflowing device is flat on the described LOAD CELLS 5.
Hydraulic selector is attached to the vertical plane of overflowing device inwall, and it reflects the liquid level position of certain orthobaric volume, and battery valve is fixed on the bottom sides of overflowing device, with the flow through bleeder quantity of overflowing device of control runoff, prevents the alluvial of silt simultaneously.
When the runoff of q.s flows into overflowing device 2 through drainage tube 1 continuously, because the control of solenoid valve (relay switch), a large amount of water inlets forms relative current stabilization state and raises its liquid level gradually in overflowing device, when liquid level rises to built-in level switch, just triggering LOAD CELLS once moves, note the weight of overflowing device when filling the known volume runoff, the back battery valve of weighing is opened sluicing, close Sheng runoff next time after the sluicing again, the machine preset program is handled the sediment charge that can detect in a certain moment runoff as calculated.
Level switch is a prior art, can adopt two electrodes to make.When water level reaches the electrode height position, two electrode conductions, make the relay adhesive through transistor amplifier, its normally opened contact is connected simultaneously, current signal adds to LOAD CELLS, weight of trigger recording, and alternating current (as 220 volts) is added on the solenoid valve, solenoid valve is opened, and discharges the water in the overflowing device.
Claims (1)
