Description
Technical field
The utility model relates to a kind of leakage visualizer.
Background technology
At present, analysis to nitrogen, phosphorus content in the observation of rice field underground leakage amount and the rice field underground leakage water, mainly be to calculate according to the irrigation tests standard to obtain, its method is: adopt to steam by rice field tatol evapotranspiration and leakage and ooze the method mensuration that device combines with the sub-district, cell measurement tatol evapotranspiration and field leakage sum, steaming is oozed device and is measured tatol evapotranspiration, calculates leakage by the two difference.Simultaneously, also ooze device and field, sub-district face has no water layer, adopt different computing formula to calculate respectively according to steaming.But mainly there is following problem in this leakage observation procedure: because device is oozed in steaming and two districts of little differentiation are observed respectively, therefore often the soil water regime of the two differs greatly, and accuracy is lower; Owing to steam the setting of oozing device, exist all the time and steam the field face boundary effect of oozing device; Because the field face has the boundary concept obfuscation of no water layer, when practical operation, be difficult to hold; Because related observation content is many, causes big error easily.
The utility model content
The utility model is the lower problem of observation accuracy that has the leakage observation procedure now in order to solve, thereby a kind of buried leakage visualizer is provided.
Buried leakage visualizer, it comprises vacuum extractor, percolating water extraction flask, obturator, drinking-water pipe, draft tube and concave bottom formula leakage water collecting device; The bottom of concave bottom formula leakage water collecting device has water delivering orifice and air intake opening, and described air intake opening is communicated with the gas outlet of draft tube, and the water delivering orifice of concave bottom formula leakage water collecting device is communicated with the water inlet of drinking-water pipe; Obturator has water inlet and gas outlet with the opening sealing of percolating water extraction flask on the described obturator, the water delivering orifice of described drinking-water pipe is communicated with the percolating water extraction flask by the water inlet on the obturator; The bleeding point of vacuum extractor is communicated with the percolating water extraction flask by the gas outlet on the obturator.
Beneficial effect: the utility model in use, the mode that concave bottom formula leakage water collecting device makes progress with opening is imbedded in the soil to be measured, seepage is after a period of time, adopt vacuum extractor that the percolating water extraction flask is evacuated, under the effect of vacuum pressure, the water in the seepage water bottle enters in the percolating water extraction flask, measures the water yield in the percolating water extraction flask, realize the observation of leakage, observation accuracy height.
