Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to an environmental monitoring groundwater well protection device. Background Art

[0002] At present, environmental monitoring uses a well drilling machine to make groundwater sampling wells. After the groundwater sampling well is completed, the sleeve filter device of the well is made of polyvinyl chloride pipes. In order to facilitate use, the well pipe must leak out above the ground. The ground part is easily damaged and unsafe. It is easy to mix with other impurities, and the surrounding surface water is also easy to flow in, affecting the groundwater quality indicators. Therefore, a protective device must be installed at the place where the well pipe of the groundwater monitoring well leaks out of the ground to prevent damage to the well pipe on the ground and external foreign matter from entering and interfering with the water quality.

[0003] Reference announcement number CN213657944U is a bottom-embedded groundwater environment monitoring wellhead protection device, which includes an upper cover, a box located below the ground, and a detection device. The upper cover is closed on the box, the box is mounted on the monitoring well, and the detection device is located on the box. This device has a box arranged on the outside of the monitoring well. If the seal of the upper cover fails and contaminated water enters, it will directly enter the box. The detection device can detect the sealing of the upper cover and the box. If the seal fails and contaminated water enters the box, the detection result will be notified to the staff, thereby reducing the possibility of contaminated water entering the monitoring well. According to the above, although this protection device can be well applied, it is usually not convenient to lock it on the outside of the well pipe, and it is difficult for a dedicated person to open and close it. It is easy for an outsider to accidentally open the protection device and damage the well pipe, which needs to be improved. Summary of the Invention
