Portable non-disturbance water intaking device and water intaking method thereof

Abstract

The invention relates to the technical field of water intaking, in particular to a portable non-disturbance water intaking device and a water intaking method thereof. The portable non-disturbance water intaking device comprises an air bag, a telescopic rod, an inflating device, a four-way joint and a water intaking pipe; the air bag is provided with a vertically-through penetrating hole, the bottom end of the telescopic rod penetrates through the penetrating hole of the air bag, and the top end of the telescopic pipe is communicated with the bottom end of the four-way joint; the output end of the inflating device is provided with a first air supply pipe and a second air supply pipe, the output end of the first air supply pipe is communicated with the left end of the four-way joint, the output end of the second air supply pipe is communicated with the air bag, and the first air supply pipe and the second air supply pipe are each provided with a switch valve; and the bottom end of the water intaking pipe sequentially penetrates through the four-way joint and the telescopic pipe from the top end of the four-way joint, an exhaust pipe is arranged at the right end of the four-way joint, and an exhaust valve is arranged at the exhaust pipe. When the water intaking device is used for taking water, the water intaking device can adapt to a complex in-well environment, disturbance to a water sample is reduced, and particularly, the loss of organic matters in a volatile organic water sample collection process can be effectively avoided, and therefore the accuracy of detection data is ensured.

Description

technical field [0001] The invention relates to the technical field of water intake, in particular to a portable non-disturbance water extractor and a water intake method thereof. Background technique [0002] At present, groundwater sampling mainly adopts buckets and various types of pumps to collect water. The buckets are mainly open type, closed type water dispensers and Baylor tubes. Various types of water pumps include inertial pumps, bladder pumps, air lift pumps, submersible pumps and self-priming pumps. Both the Baylor tube and the low-flow pump have many disadvantages in the process of washing wells and sampling groundwater. Baylor pipe: When the well is too deep, it is laborious and time-consuming to lift water; it is easy to cause disturbance, and there are more impurities in the water. It is not easy to reach the water surface; each well needs to replace the Baylor tube, resulting in waste of raw materials. Low-flow pump: Low-flow pumps are limited by head an...

Problems solved by technology

Both Baylor tubes and low flow pumps have many disadvantages in groundwater well cleaning and sampling

Baylor pipe: When the well is too deep, it is laborious and time-consuming to lift water; it is easy to cause disturbance, and there are more impurities in the water. Difficult to reach the water surface; Baylor tubes need to be replaced for each well, resulting in waste of raw materials

Low-flow pump: Low-flow pumps are limited by head and flow, and if the well depth is too deep, water will not flow out; long pumping time will easily cause disturbance, resulting in more water impurities, and the loss of organic matter cannot be avoided in the collection of volatile organic matter water samples, which will affect Check the accuracy of the data
