Problems solved by technology

[0003] Although geothermal energy is a renewable energy, it still needs to be used economically. At present, conventional geothermal wellheads are generally in an open and closed state, that is, hot water will always flow out, resulting in a large waste of energy.

Abstract

The invention provides a wellhead device for geothermal energy. The wellhead device for geothermal energy comprises a fixing sleeve, a bottom sleeve, a rotating structure and a sealing structure; thesealing structure is arranged in the fixing sleeve; the sealing structure comprises a screw rod, a bearing, a sealing plug, a sealing ring and a limiting ring; the screw rod is rotationally connectedinto the rotating structure; the bearing is fixed to the outer portion of the bottom end of the screw rod; the circular sealing plug is fixed to the outer portion of the bearing; the screw rod is rotationally connected with the sealing plug through the bearing; the sealing ring is fixed to the outer portion of the sealing plug; and the limiting ring is arranged at the bottom end of the sealing plug. The wellhead device for geothermal energy has the advantages of being capable of sealing a wellhead and good in sealing performance.

Description

technical field [0001] The invention relates to the technical field of utilization of geothermal energy, in particular to a wellhead device for geothermal energy. Background technique [0002] Geothermal heat is a source of energy derived from nuclear fission within the Earth. The temperature of lava ejected from volcanoes on the earth is as high as 1200°C to 1300°C, and the temperature of natural hot springs is mostly above 60°C, and some are even as high as 100°C to 140°C. This shows that the earth is a huge heat reservoir, containing huge heat energy. This heat seeps out to the surface, so there is geothermal heat. Geothermal energy is a kind of clean energy and renewable energy, and its development prospect is very broad. In order to utilize geothermal energy, people often set up wellheads at geothermal outlets. [0003] Although geothermal energy is a renewable energy, it still needs to be used economically. At present, conventional geothermal wellheads are generall...
