Problems solved by technology

[0003] However, during the use of the above-mentioned geothermal extraction equipment, due to the deep depth of these abandoned thermal wells, a large amount of heat will inevitably be lost during the transmission of the extracted heat energy, reducing the heat that can be obtained per unit time, which is extremely Greatly affects work efficiency; at the same time, water is usually used as a carrier when extracting heat energy, but the operator cannot accurately know when the water is used up, which brings inconvenience to the operation

Abstract

The invention provides terrestrial heat extraction equipment with a heat-preserving function. The terrestrial heat extraction equipment with the heat-preserving function comprises a main body mechanism, a water input pipe, a water output pipe, a pressure water pump and a heat exchanger. The main body mechanism comprises a main body shell, a heat absorbing face, a heat preserving vacuum cavity anda partition plate. The heat preserving vacuum cavity is formed in the main body shell. The heat absorbing face is fixedly connected to the bottom of the main body shell. The partition plate is fixedlyconnected to the portion, distancing from the bottom by one third, of the inner side wall of the main body shell. The water input pipe is fixedly installed on one side of the top of the main body shell. The water output pipe is fixedly installed on one side, located on the top of the main body shell, of the water input pipe. The terrestrial heat extraction equipment with the heat-preserving function has the advantages that operation is convenient, heat can be kept from being dispersed in the terrestrial heat extraction process to the greatest extent, the working efficiency is improved, and meanwhile, an operator can be accurately reminded when the water is used up.

Description

technical field [0001] The invention relates to the technical field of geothermal extraction, in particular to a geothermal extraction device with heat preservation function. Background technique [0002] With the continuous development of science and technology, and the large demand for energy in today's society, the development of new energy sources such as geothermal is getting more and more in-depth. In actual production, hydrothermal geothermal systems and well hot spring systems need to dig deep wells. During the excavation process and subsequent use of the deep well, there is no groundwater hot water after the completion of the geothermal well, or the water output is small, or the groundwater level drops during use, and the hot water in the well cannot be extracted, etc., it becomes a waste geothermal well. , making it unusable. The depth of such waste geothermal wells is generally about 2,000 meters, and the temperature at the bottom of the well is about tens of deg...
