Description

Technical Field

[0001] This utility model relates to the field of geothermal exploration technology, and in particular to a water temperature monitoring device for geothermal wells. Background Technology

[0002] Geothermal energy is the heat resource inside the Earth that can be economically utilized by humankind. To utilize geothermal energy, it is necessary to drill geothermal wells. A geothermal well refers to a method and device for generating electricity from geothermal energy or hot spring water with a temperature greater than 30°C at a depth of about 3,500 meters. Geothermal energy is divided into three categories: high temperature, medium temperature, and low temperature. In order to monitor the water temperature, water temperature monitoring devices are usually used to provide important data support for geothermal exploration, geothermal resource development, utilization, and management.

[0003] The geothermal well water temperature monitoring device disclosed in announcement number CN221346906U can be used to place the temperature measuring component pulled by the pull rope at different heights through the action of the pull component. Depending on the height, the geothermal well water temperature at different levels can be recorded in real time, and the average value of multiple measurements can be taken to obtain a relatively accurate temperature of the water inside the geothermal well, which further improves the accuracy of geothermal well measurement and control.

[0004] However, the water temperature monitoring device for this geothermal well has the following disadvantages: when the temperature detection component moves inside the geothermal well, it may collide with the well wall. At the same time, fluid flow or pressure changes inside the well may cause the sensor to shake, making it difficult to protect the detection equipment. In addition, after the temperature measurement is completed, the water temperature monitoring device needs to be stored away. Sand particles or water stains from inside the geothermal well may remain on the surface of the cable, making cleaning time-consuming and hindering the speed of storage. Utility Model Content

[0020] 1. The geothermal well water temperature monitoring device, through the setting of protective components, has a metal limiting tube installed on the surface of the armored water temperature detection module during use. The counterweight provides weight, keeping the armored water temperature detection module in a vertical position and reducing friction with the well wall. At the same time, the protective ring is made of perfluoroether rubber, which has the characteristics of corrosion resistance, high temperature resistance and elasticity, reducing the impact force, thereby protecting the armored water temperature detection module.
