Description

Portable well washing device

Technical Field

The utility model relates to a detection technology especially relates to groundwater water quality testing technique, specifically is a portable well washing device.

Background

The conventional detection of the water quality of underground water is realized by an underground water environment monitoring well (hereinafter referred to as a monitoring well). Through the monitoring well, the underground water environment quality condition and the dynamic distribution change condition of pollutants in the underground water body can be accurately mastered. Because the monitoring well has the possibility of being polluted, the monitoring well needs to be regularly washed in daily monitoring so as to ensure the accuracy of water quality monitoring data; when abnormal data occurs during monitoring, well flushing operation is also required to clear the cause so as to eliminate whether the abnormal data is a pollution factor of the monitoring well.

For water quality monitoring in a city, the number of monitoring wells is large, the geographical positions are widely distributed, the geological conditions are different, and the field conditions are limited when conventional well washing sampling operation is carried out, so that the well washing equipment is convenient to transport and carry.

At present, common portable well-flushing equipment comprises an air bag pump, a Beller tube, a submersible pump and the like. The Beller tube is mainly used for collecting water samples, and when the Beller tube is used for washing a well, sediment in the well is difficult to stir, and the bottom of the well cannot be thoroughly cleaned. The immersible pump because will sink to the surface of water below, the mechanical structure of motor self can influence quality of water, and the motor generates heat and also can influence quality of water, and the monitoring well is all small-bore usually moreover, if the well depth is great, just can only select the immersible pump that the draw ratio is great, and the volume quality of this kind of immersible pump is also corresponding great, and transport, installation, well descending all are very hard, consequently, its well-flushing operation that is used for irrigation well usually, is not suitable for the well-flushing operation of monitoring well. The air bag pump can discharge well water mixed with impurities while flushing the well, has good well flushing effect but limited lift, and is mainly applied to shallow water level monitoring wells; when the device is applied to a monitoring well with a deep water level, the water outlet speed is low, and sometimes water cannot be discharged.

In the prior art, portable well washing and sampling integrated equipment is available, the principle of an air bag pump is basically adopted, for example, a low-speed well washing sampling system produced by a certain company, the limitation of the air bag pump cannot be broken through in the integrated equipment, and the pumped water volume is extremely small in the well washing process, so that the well washing speed is still low. By adopting the low-speed well washing sampling system, the conventional well washing operation has low efficiency and long time consumption; for monitoring points with water quality pollution problems, repeated well flushing operation is sometimes needed for determining reasons, and the low-speed well flushing sampling system also seriously slows down the working progress.
