Abstract
The utility model provides a point source infiltration wetting front testing device based on a Markov bottle. An external connection device is connected on the basis of the Markov bottle. The external connection device comprises a support, a transparent water bottle, a connecting pipe, a thin hose provided with a valve and the like. During testing, a water dripping process of a dripper can be monitored through observing the variation of the water level in the transparent water bottle, and the test accuracy is improved.
Description
Technical field
The utility model relates to wetting front proving installation under a kind of Infiltration from Point Sources condition, can the monitoring test process, improve test accuracy.
Background technology
The Ma Shi bottle is can provide with a kind of of French physicist Mariotte name the measuring apparatus of stablizing head, closed cylinder, draft tube (water inlet pipe), vent port, outlet valve, graduated tube etc., consist of, the scientific research institutions such as hydrogeology, water conservancy, agricultural and production division are multiplex in monitoring daily evaporation amount and infiltration capacity.Drip irrigation is a kind of emerging irrigation technique, with traditional flood irrigation, essential distinction is arranged, for Infiltration situation (wetting front) under the research condition of drip irrigation, scientific research institutions adopt the Ma Shi bottle as test unit more, to study soil body wetness conditions under a certain water dropper flow, but the test discovery, water dropper instability of flow in the process of dripping, can not be monitored process of the test, easily test findings be impacted.
Summary of the invention
Using in order to solve the deficiency that the Ma Shi bottle can not be monitored process of the test as the Infiltration from Point Sources test unit, the utility model has designed a kind of external device based on the Ma Shi bottle, this device can well be monitored the Infiltration from Point Sources process of the test, to improve the precision of test.
The utility model solves the technical scheme that its technical matters adopts: in the Infiltration from Point Sources test, generally at the direct external delivery hose of Ma Shi bottle water delivering orifice, connect water dropper at hose end, in test, the water dropper uninterrupted is controlled by Ma Shi bottle outlet valve aperture, after regulating flow, start test, in process of the test, whether head changes can not draw by observation, and constant current just can draw wetting front accurately, therefore extremely important to the monitoring of process of the test.For this problem, the technical program, on the basis of Ma Shi bottle, has designed an external device, by support, connecting pipe, transparent water bottle (aperture is opened in bottom), form with small hose of minor valve etc.During test, the Ma Shi bottle is full of to water and is placed on support, keep bottle vertical, close gas outlet; Transparent water bottle is inverted and is suspended on support, the transparent water bottle suspension height be bottom, the bottle end a little more than Ma Shi bottle rising pipe center 3-4cm, and a bottle end far from ground, certain altitude is arranged; Small hose with minor valve is inserted in the transparent water bottle with rubber plug, make on small hose minor valve in closed condition; Connecting pipe is full of to water, and one terminates on Ma Shi bottle rising pipe, and an end inserts in transparent water bottle by bottle end aperture, and makes the connecting pipe end lower than Ma Shi bottle rising pipe center 7-8cm; Open Ma Shi bottle outlet valve fully, under 7-8cm head suction function between connecting pipe end and Ma Shi bottle rising pipe, the water in the Ma Shi bottle constantly is sucked out, when the transparent water bottle middle water level rises to Ma Shi bottle rising pipe center, pressure reaches balance, and current stop; The small hose end is fixed on to a certain height (lower than bottle middle water level height), and keeps this highly constant, open minor valve on small hose, under the transparent water bottle Water Pressure, liquid will continuously outflow, and regulate minor valve aperture on small hose, obtain the required water dropper flow of test; Once the transparent water bottle middle water level descends, when the transparent water bottle middle water level during lower than Ma Shi bottle rising pipe center, regenerate negative pressure, current flow out again until water level flushes with the rising pipe center, reach dynamic balance state, to keep the bottle middle water level by constant, guarantee small hose end water dropper constant flow; In test, the small hose end, in stationary state, by observing transparent water bottle middle water level situation of change, can learn whether small hose end flow changes, and realizes the monitoring to the process of dripping, and improves the precision of test.
The beneficial effects of the utility model are, in test, by observing transparent water bottle middle water level situation of change, realize the monitoring to the process of dripping, simple in structure.
The accompanying drawing explanation
Below in conjunction with Fig. 1 and embodiment, the utility model is further illustrated.
Fig. 1 is the Infiltration from Point Sources wetting front proving installation based on the Ma Shi bottle.
In figure 1---air intake opening/water inlet, 2---exhaust valve, 3---water inlet pipe/blowdown pipe, 4---graduated tube, 5---the rising pipe valve, 6---connecting pipe, 7---transparent water bottle, 8---small hose, 9,11---support, 10---minor valve on small hose, 12---the Ma Shi bottle, 13---the test soil body, 14---gas outlet, 15---rising pipe.
Embodiment
During test, support (9,11) is placed on the test smooth position of the soil body (13), keeps certain distance, Ma Shi bottle (12) is placed on to support (11) upper, keep plumbness; Transparent water bottle (7) is inverted and is suspended on support (9) above, make transparent water bottle (7) bottom a little more than rising pipe (15) center 3-4cm; Open exhaust valve (2), close rising pipe valve (5), by air intake opening/water inlet (1), Ma Shi bottle (12) is full of to water, close exhaust valve (2); Small hose (8) is inserted to water bottle bottom, and the fixation ends position, height, lower than rising pipe (15) center, is closed minor valve on small hose (10); Connecting pipe (6) is full of to water, and it is upper that an end is connected to rising pipe (15), and an end inserts in transparent water bottle (7), makes end lower than rising pipe (15) center 7-8cm; Open rising pipe valve (5), under head suction function between connecting pipe (6) end and rising pipe (15), water in Ma Shi bottle (12) will constantly be sucked out, until transparent water bottle (7) middle water level rises to rising pipe (15) center; Open minor valve on small hose (10), controlling opening of valve makes aquifer yield reach the required water dropper flow of test; During test, once transparent water bottle (7) middle water level is lower than rising pipe (15) center, to produce negative pressure, in Ma Shi bottle (12), liquid will be sucked out again, transparent water bottle (7) middle water level will flush with rising pipe (15) center again, transparent water bottle (7) middle water level is remained unchanged, thereby make small hose (8) end water dropper flow keep constant; Change by observing transparent water bottle (7) middle water level, can be monitored the test process of dripping.
Claims (1)
1. the Infiltration from Point Sources wetting front proving installation based on the Ma Shi bottle, by Ma Shi bottle, connecting pipe, support, transparent water bottle, form with small hose of minor valve etc., it is characterized in that: a transparent water bottle is inverted and is suspended on support, the bottle end, is a little more than Ma Shi bottle rising pipe center, by connecting pipe, the Ma Shi bottle is connected with transparent water bottle, the connecting pipe end, lower than Ma Shi bottle rising pipe center, forms certain discrepancy in elevation, regulates minor valve on small hose and obtains the required water dropper flow of test.
