Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a staged water pumping device for geothermal new energy. Background Art

[0002] Geothermal energy is a green, low-carbon, and recyclable renewable energy source. Compared with other green energy sources such as solar energy, wind energy, and tidal energy, it has the advantage of not being affected by external factors such as seasons, climate, and diurnal changes. Geothermal resources can be divided into three categories based on temperature: high temperature, medium temperature, and low temperature. The earth itself is like a huge boiler, with enormous thermal energy stored deep inside. Under the control of geological factors, this thermal energy will gather in a certain range of the earth's crust in the form of hot steam, hot water, and hot dry rocks. If the conditions for development and utilization are met, it will become a geothermal resource with development significance. At present, during the process of geothermal exploration and development and utilization, it is necessary to conduct water pumping tests on the drilling wells to obtain the hydrogeological parameters of the thermal reservoir to provide a basis for later mining and utilization.

[0003] At present, the pumping device in the existing technology only relies on water pumps to pump water. When faced with large-flow application scenarios, it cannot meet the specific fluid transportation requirements in the field of geothermal new energy exploration and development. In addition, there is no vibration reduction structure at the bottom of the water pump. When the pumping device is subjected to large vibrations, it may affect the overall operation effect of the pumping device. Utility Model Content
