Abstract
A silt content dynamic detection device is composed of a drainage groove (1), a flowing device (2), a liquid level switch (3), a sluice valve (4) and a weighing sensor (5). The liquid level switch (3) is arranged on the vertical surface of the inner wall of the flowing device (2) in a built-in way, the sluice valve (4) is fixed at the bottom side surface of the overflowing device, and the whole flowing device (2) is horizontally arranged on the weighing sensor (6). When enough channel water intermittently flows into the flowing device (2) by the drainage groove (1), only a small quantity of channel water is drained owning to the control of the sluice valve (4), the rest channel water forms relative steady flow in the flowing device (2) and gradually lifts the liquid level, when the liquid level rises to the built-in liquid level switch (3), the weighing sensor (5) is triggered to operate, and the weight of the flowing device (2) when the flowing device is filled with channel water in known volume, and the silt content at one moment in the channel water can be detected by computer processing.
Description
One, technical field
The present invention relates to a kind ofly, in department's water quality detections such as the field irrigation of low discharge, environmental protection sediment charge in the flowing water is carried out the device of in good time detection of dynamic at low water head.It has improved efficient and accuracy that the flowing water sediment charge detects significantly.
Two, background technology
The sediment charge that detects in the water quality in departments such as irrigation and water conservancy, forest ecology, environmental protection is an important index.
Conventional method is: artificial field sampling, then indoor to operations such as sample liquid filter, dries, weighs, determine the sediment charge of sample liquid, and then infer the sediment charge of sampling flowing water.
The subject matter that exists is: poor in timeliness, operation is many, from sampling testing result, often needs a few days, and detects the cost height.
Three, summary of the invention
The problem to be solved in the present invention provides a kind of simple in structure, operate, safeguard silt content dynamic detection device easily, as shown in Figure 1, this device is made of drainage trough (1), overflowing device (2), level switch (3), emptying valve (4), LOAD CELLS (5).Level switch (3), attached to the vertical plane of overflowing device (2) inwall, it reflects the liquid level position of certain orthobaric volume, and emptying valve (4) is fixed on the bottom sides of overflowing device (2), with the flow through bleeder quantity of overflowing device (2) of control water in a canal, prevent the alluvial of silt simultaneously.Whole overflowing device (2) is flat on the LOAD CELLS (5).
Beneficial effect is: introduce the overflowing device (2) 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, improve the ageing and accuracy that detects, reduce the energy consumption that detects and detect cost.
Four, description of drawings
The invention will be further described below in conjunction with accompanying drawing.

1, drainage trough, 2, overflowing device, 3, level switch, 4, emptying valve, 5, LOAD CELLS.
Five, concrete implementation content
As shown in Figure 1, silt content dynamic detection device is made of drainage trough (1), overflowing device (2), level switch (3), emptying valve (4), LOAD CELLS (5).Water in a canal intermittence ground warp drainage trough (1) inflow overflowing device (2) when q.s, because the control of emptying valve (4) only allows a small amount of water in a canal to discharge, a large amount of water inlets forms relative current stabilization state and raises its liquid level gradually in overflowing device (2), when liquid level rises to built-in level switch (3), just triggering LOAD CELLS (5) once moves, note the weight of overflowing device when filling known volume water in a canal (2), the machine preset program is handled the sediment charge that can detect in this open channel of a certain moment (small stream ditch) flowing water as calculated.
Claims (1)
- A kind of silt content dynamic detection device, it is made of drainage trough (1), overflowing device (2), level switch (3), emptying valve (4), LOAD CELLS (5), it is characterized in that described overflowing device (2), be to be flat on the LOAD CELLS (5), and be built-in with level switch (3) and emptying valve (4).
