Utility model content
The utility model technical issues that need to address are:
Existing underground water meter flow pumping system, bubble and sediment and sediment in the underground water for pumped of drawing water can be every Cut off the water supply stream, reduce the flow velocity of current, cause flow measurement to produce error;Current fluid cross-section product is obstructed, influences water meter, electromagnetic type With the error in dipping of ultrasonic flow meter;Bubble in current may influence the chemical property of fluid, so as to cause flow There is error in dipping in meter;The underground water that suction pump extracts contains the impurity such as silt, to water meter, the life-span of flowmeter and accuracy of detection There is bad influence.
The utility model takes following technical scheme:
A kind of ground water drainage system exhaust draws the soaring pipe device of sand, including drainpipe 2, drinking-water pipe 4, water pump, flowmeter; The accumbency of drainpipe 2 is set, and opens up at least one steam vent above tube wall, the steam vent is fixedly connected with blast pipe 1;Institute State the corresponding hydraulic pressure that the hydraulic pressure in drainpipe 2 is less than exhaust gas pipe height;The end of drainpipe 2 is connected with drinking-water pipe 4, described to take out Water pump 3 is set on water pipe 4, and the end of drinking-water pipe 4 is additionally provided with flowmeter.
Further, the blast pipe 1 is welded and fixed with drainpipe 2.
Further, the blast pipe 1 is set straight up.
Further, the quantity of the blast pipe 1 on drainpipe 2 sets some, such as 3-5 roots.
Further, the drinking-water pipe 4 is flexible pipe, and the drainpipe 2 and blast pipe 1 are hard tube.
Further, the caliber of the blast pipe 1 is less than the caliber of drainpipe 2.
Further, the bottom of the drainpipe, sediment tube, the sediment tube are provided with the position of the face of blast pipe 1 Filter screen 5 is provided with, for precipitating placer.
Further, current meter is set on the sediment tube.
Further, valve is set under the sediment tube, for water sampling and draws sand.
The beneficial effects of the utility model are:
1) bubble in current and sediment are gradually discharged in drainpipe by blast pipe, improve the accurate of flowmeter measurement Degree;
2) bubble and sediment is avoided to obstruct current fluid cross-section product, thereby using water meter, electromagnetic type and ultrasonic type flow Timing will not produce extra error;
3) avoid the material in bubble and current that chemical reaction occurs so as to avoid influenceing the chemical property of fluid, further Avoid error in dipping;
4) water pipe exhaust, drainage speed are improved;
5) drainpipe suspension cleaning efficiency is improved;
6) blast pipe is versatile and flexible, changeable, can be high or low, and adds blast pipe according to law of connected vessels, improves draining Pipe resistance to compression, draining, desilting and relay effect.
Brief description of the drawings
Fig. 1 is that the utility model ground water drainage system exhaust draws the soaring pipe device of sand
In figure, 1. blast pipes, 2. drainpipes, 3. water pumps.
Embodiment
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of ground water drainage system exhaust draws the soaring pipe device of sand, including drainpipe 2, drinking-water pipe 4, water Pump, flowmeter;The accumbency of drainpipe 2 is set, and at least one steam vent, the steam vent and blast pipe 1 are opened up above tube wall It is fixedly connected;Hydraulic pressure in the drainpipe 2 is less than the corresponding hydraulic pressure of exhaust gas pipe height;The end of drainpipe 2 and drinking-water pipe 4 Connect, water pump 3 is set on the drinking-water pipe 4, and the end of drinking-water pipe 4 is additionally provided with flowmeter.
In this embodiment, the blast pipe 1 is welded and fixed with drainpipe 2.
In this embodiment, the blast pipe 1 is set straight up.
In this embodiment, with continued reference to Fig. 1, the quantity of the blast pipe 1 on drainpipe 2 sets some.
