Technical Field

The utility model relates to a groundwater velocity of flow measures technical field, especially relates to an downthehole vertical flow and moves measuring wire device.

Background

The single-hole point dilution method for determining the horizontal flow rate of an aquifer refers to: the water column in the borehole is marked by the tracer, and due to the flow of the leaking water, water in the aquifer upstream of the borehole enters the borehole, while the water marked by the tracer in the borehole migrates downstream of the aquifer. Under the condition of ensuring that the water quantity in the drill hole is not changed, the tracer continuously moves out of the drill hole to generate the phenomenon that the concentration of the tracer is diluted. It is clear that the dilution rate of the tracer is closely related to the permeation flow rate of the leakage water. According to the mathematical relationship between the two, the concentration of the tracer in the borehole can be detected at different moments, and the permeability flow rate of the aquifer can be calculated. The method is called a single-hole tracer dilution method because the method is carried out in a single hole, namely the feeding of the tracer and the detection of the concentration of the tracer are carried out in the same drilling hole. When there is the vertical stream of groundwater in the drilling, also can cause the tracer concentration to dilute, lead to horizontal velocity of flow to calculate and appear great error, consequently need survey the downthehole vertical velocity of flow. In the existing measuring method, after a tracer is generally put into a drill hole, a putting device is lifted out of the hole and then a detector is put into the hole to test the concentration data of the tracer, but under the condition of large flow rate of underground water, a large measuring error is often generated.

Accordingly, there is a need for an in-bore vertical flow mobile metering device that addresses one or more of the problems set forth above.
