Description

Technical Field

[0001] The utility model relates to the technical field of geothermal energy pipe laying, in particular to a geothermal energy vertical pipeline pipe laying device. Background Art

[0002] The temperature inside the Earth is as high as 7000°C, and at a depth of 80 to 100 miles, the temperature drops to 650 to 1200°C. Heat is transferred closer to the surface through the flow of groundwater and the upwelling of molten rock to the crust 1 to 5 kilometers below the ground. The hot molten rock heats the nearby groundwater, which eventually seeps out of the ground. The simplest and most cost-effective way to use geothermal energy is to directly access these heat sources and extract their energy.

[0003] The application number is CN202320555931.2. The utility model discloses a geothermal energy vertical pipeline lowering device, including a guide cylinder, a plurality of guide components are arranged around the center of a circle inside the guide cylinder, the guide components all include guide protection plates, the guide protection plates all include petal-shaped lower pressure plates and arc-shaped guide plates, a plurality of shaft rods arranged around a circle are inserted on the side wall of the guide cylinder, one end of the shaft rod is threadedly connected to the side wall of the arc-shaped guide plate, and the other end of the shaft rod is threadedly connected to a nut, a spring is connected between the nut and the side wall of the guide cylinder, and the spring is sleeved on the shaft rod; the utility model adopts a guide component, and guides and protects the lowering pipe by squeezing the guide protection plate through the lowering pipe of the geothermal pipe, so as to avoid manual support for guiding the lowering pipe.
