An automatic water level and temperature monitoring system based on shallow geothermal wells

Abstract

The invention provides a water level and water temperature automatic monitoring system based on a superficial layer geothermal well. The water level and water temperature automatic monitoring system based on the superficial layer geothermal well comprises a well cementation section and a geothermal well of a filter well section from up to down, and the well cementation section comprises well wall pipes six meters long; the filter well section comprises water permeable pipes six meters long, the space between the permeable well and a well body is filled with cobbles and a sediment well section five meters long is arranged at the bottom of the filter well section, the diameter of the sediment well section is smaller than the diameter of the well cementation section and the filter well section; a water temperature information collection device is arranged on a filter, the water information collection device comprises a water temperature sensor, and a thermosensitive resistance wire arranged on the water temperature sensor is wound on the outer surface of the filter; and a geothermal well opening is provided with a water level information collection device comprising an ultrasonic wave water level sensor and a general packet radio service (GPRS) module, and all monitoring information is transmitted to a servicer through the GPRS. The water level and water temperature automatic monitoring system based on the superficial layer geothermal well can accurately measure the water temperature of the geothermal well, measuring information is transmitted to the servicer in real time, and an accurate data foundation is provided for thermal energy application.

Description

technical field [0001] The invention relates to the technical field of geothermal detection, in particular to an automatic monitoring system for water level and temperature based on shallow geothermal wells. Background technique [0002] Geothermal energy is a kind of renewable clean energy, the most common is natural hot spring, which is favored by people, and now geothermal energy has been widely used in various fields. [0003] Geothermal wells are an important step in the utilization of geothermal resources. For different geology, the well structure of geothermal wells is also different. The filtering function of the geothermal well is very important for the subsequent use of geothermal heat. If sediment enters the geothermal well, the submersible pump will pump out the water containing sediment for use, which will easily cause damage to the equipment, affect the operation of the system, and cause major losses; The amount of sediment entering the geothermal well will in...

Problems solved by technology

This detection method has certain defects. In the process of pumping groundwater, it will inevitably cause heat loss, resulting in large deviations in water temperature measurement. If you want to accurately detect, you need to properly heat the water pumped to the surface and then measure it. , resulting in heat loss
