Description

Technical Field

[0001] The utility model relates to the technical field of water level measurement, in particular to a geothermal well water level measuring device. Background Art

[0002] Geothermal well refers to a method and device for generating electricity using geothermal energy from a depth of about 3,500 meters or hot spring water with a water temperature greater than 30°C. Geothermal energy is divided into three categories: high temperature, medium temperature, and low temperature. Since the water level in a geothermal well changes all the time, it is necessary to measure the water level of the geothermal well to understand the situation inside the geothermal well.

[0003] After searching, the patent with announcement number CN219034706U discloses a geothermal well water level measuring device, which is convenient for limited fixing by providing a pipe wall fixing rod structure. The concave magnetic plate of the pipe wall fixing rod is sleeved on the geothermal well pipe and is effectively adsorbed and fixed to avoid tilting during fixation, making it easy to install and connect quickly. Then, due to the fixing screws on the supporting concave rod, it is easy to install and fix. In this way, the overall installation is more efficient. The supporting concave rod is fixed to the top panel due to the welding top plate, so that the top panel is easy to place stably.

[0004] The patent with announcement number CN219864915U discloses a geothermal well water level measuring device, which can adjust the height of the take-up wheel through a height adjustment component so that the horizontal baffle on one side of the L-shaped plate is flush with the wellhead of the geothermal well, so as to accurately measure the water level of the geothermal well, solving the problem that the height of the take-up wheel of the existing geothermal well water level measuring device cannot be adjusted and the water level cannot be measured for geothermal wells of different heights.

[0005] Although both of the above-mentioned solutions can effectively measure the water level of geothermal wells, their water level probes are poorly protected and may collide with the well wall during the descent in the well, which may easily cause damage to the probes. In addition, the depth of geothermal wells can easily reach thousands of meters, and water level probes lacking counterweights are difficult to descend quickly in the well, which needs to be improved.
