[0002] Groundwater refers to water stored in the pores of rocks below the ground. It is an important component of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industrial conditions and cities. Monitoring wells are special wells completed by drilling to monitor changes in groundwater levels, water temperatures and water quality. It is usually necessary to set up relevant equipment on the inner wall of the well and set relevant sensors underground. The measured data is transmitted by people or through wireless communication. In order to protect the equipment placed in the well, the monitoring wellhead needs to be protected.
