Abstract
The invention provides a drainage type ombrometer. The main body of the ombrometer is a cylinder with lateral gaps (straight gaps or V-shaped gaps), or a reverse conical or reverse pyramidal rain gauge bucket, when flowing into the rain gauge bucket, the rain is simultaneously drained from the lateral gaps of the rain gauge bucket, because the drainage amount equals to the water inlet amount, so the rainfall can stop at a horizontal plane with a certain height in the rain gauge bucket, and the horizontal plane is the instant rainfall strength at the moment. The rain weight can be subjected to data processing conveniently when the rain gauge bucket is used to detect the level height. The drainage type ombrometer has the advantages of large range, no intermittent operation, simple structure and high accuracy.
Description
Affiliated technical field:
The present invention relates to a kind of instrument that detects the rainfall precipitation intensity.
Technical background:
The instrument of monitoring rainfall precipitation intensity mainly divides two kinds at present, though one is the tipping-bucket rain-gauge of Englishman's invention in 1826. and use the basic inventive principle of improvement over more than 100 year till today and do not become; Another kind is a siphon rainfall recorder. these two kinds of rain gages all have identical shortcoming, and intermittently discontinuous action is all arranged.
Tipping-bucket rain-gauge is by two tipping buckets that stir water receiving up and down, and a tipping bucket fills rainwater, turns down simultaneously rainwater is inclined to, and the tipping bucket that rolls up begins to connect rainwater and fills and turn down and incline to rainwater, and tipping bucket drives a magnet steel and makes tongue tube work counting.The volume of tipping bucket is certain, can obtain the rainfall precipitation intensity according to time and tipping bucket number of times.Shortcoming is that the mechanical clearance action is arranged.Because the tipping bucket capacity is certain, the heavy rain of can light rain being failure to actuate turns over too late, has to spill, and influences measuring accuracy, accuracy.
The precipitation gauge of siphon rainfall recorder is when precipitation is filled with more, and U trap is taken out ponding in the tube, and precipitation gauge begins water receiving again, produces intermitten.And the cleaning of hydrocone type glass tube is difficult, behind the cleaning U trap, installs and adjusts also than bothering.
Summary of the invention:
The present invention is a kind of new-type rain gage, and its main body is the container of drum type brake or rounding bevel-type or chamfered edge bevel-type.Container side has opened vertical masonry joint or V-arrangement cracks.When rainwater enters the precipitation gauge of this cylinder or back taper, rainwater can release from vertical masonry joint or V-arrangement latasuture simultaneously, bleeder quantity=inflow, precipitation will be parked on the surface level of certain altitude in precipitation gauge like this, this surface level just can be represented instant at that time rainfall amount with scale, or claims rainfall intensity.When rainfall intensity was bigger when rainfall amount is bigger, the surface level in the precipitation gauge of cylinder or back taper can be elevated to another height; Otherwise when rainfall amount reduced, the surface level in the precipitation gauge can drop to lower height, and the scale on cylinder or the back taper precipitation gauge can reflect the intensity of rainfall amount very accurately.
Because the awl of back taper precipitation gauge point capacity vertical masonry joint or the V-arrangement little and side crack, so also can reflect to some extent when rainfall density is very little.When rainfall density is very big, also can reflect strictly according to the facts.So this invention is rainfall METHOD FOR CONTINUOUS DETERMINATION in the great scope of 0-----in principle, the big rain gage of accurately measuring of range.
This be the tipping-bucket rain-gauge siphon rainfall recorder can not compare.And its texture ratio tipping bucket type and siphon rainfall recorder are greatly simple, and cost is also much lower, without any mechanical motion mechanism and the position that will adjust.As long as when the tube inwall need clean, do simple cleaning, without any other requirement.
The mode that vertical masonry joint is arranged or have the precipitation gauge of V-arrangement latasuture can have several data monitoring and data to export with drum type brake or back taper (turbination or chamfered edge taper) and side.Add that as laser range finder or supersonic liquid level detection instrument the current stabilization dividing plate can directly be transferred to registering instrument or computer with the liquid level of this precipitation gauge, be for data processing and record:, can on roll-chart recorder, make paper setting-out record if in this precipitation gauge, put a float.
The present invention will adopt easier low cost of another kind and reliable method accurately, use the method for weighing exactly.
Surveying with laser range finder or supersonic liquid level detection instrument or float-type all is that the height of liquid level is monitored, and here, and this invention is with actual weight of rainwater in the monitoring precipitation gauge.For the rainwater in the precipitation gauge, because sluice simultaneously in the side, the height of actual rainwater can reflect the intensity of actual rainwater, and it also must have a relative weight at the rainwater of its height and position, and we can monitor the weight of rainwater in the precipitation gauge accurately with the weight sensor of electronic scale.The height-precision that the rain gage of international standard requirement at present detects the liquid level of precipitation gauge is 0.1 millimeter, precipitation gauge standard bore is 200 millimeters, 0.1 millimeter height weight is 3.14 grams, and the most general electronic scale precision is 1 gram, be better than of the accuracy requirement of existing rain gage greatly to the rainwater monitoring, illustrate that if monitor rainfall density with weighing method, precision can improve 300% at least.
Weight sensor is monitored the actual weight of rainwater in cylindrical shape and the back taper precipitation gauge, convert the instant data of rainfall density to, input computer or registering instrument get final product.
The invention will be further described below in conjunction with drawings and Examples.
Figure one is the inverted cone precipitation gauge,
Figure two is meters,
Figure three is these drainage type rain gage entity synoptic diagram.
Rain gage holds the mouth of a river 1, funnel 2, conduit 3, turbination tube 4, rainfall density scale 5, V-arrangement earial drainage latasuture 6, weight sensor seat 7, suspension cable 8, weight sensor 9, bearing plate 10, circuit board 11, computer or registering instrument 12.
Rainwater is through the udometric mouth of a river 1 of holding, and enters turbination tube 4 and releases through earial drainage latasuture 6 through funnel 2 and conduit 3, because vent flow=inflow, when inflow is big, can rise in the water level planes in the turbination tube 4.Otherwise advance amount of rainfall hour, the surface levels in the turbination tube 4 can descend, so the waters surface in the conical tube 4 are rainfall intensities at that time.Can read from the V-arrangement earial drainage latasuture 6 other metering scales of inverted cone tube 4.
Embodiment:
Figure three is drainage type rain gage entity synoptic diagram.
Rainwater holds the mouth of a river 1 through rain gage, funnel 2, and conduit 3 enters turbination tube 4, and a part of rainwater flows out from V-arrangement earial drainage latasuture simultaneously.
No matter the rain heavy rain is little, and this rain gage can both write down and report continuously accurately.The drainage type rain gage is skillfully constructed simple and convenient, safeguards also very simple and convenient.Only need clean precipitation gauge.
