Middle-deep layer underground geothermal heat exchanger convenient to install

Abstract

The utility model discloses a middle-deep layer underground geothermal heat exchanger convenient to install. The middle-deep layer underground geothermal heat exchanger comprises a geothermal heat exchanger body, a fixing plate, a fixing frame and a steel wire rope. By arranging the mounting plate and the moving wheels, the geothermal heat exchanger body can move up and down to drive the moving wheels to roll up and down on the surface of a well wall, so that the geothermal heat exchanger body can be prevented from shaking and colliding with the well wall when moving up and down; the problems that although a geothermal heat exchanger body is installed conveniently through electromagnets and clamping jaws, the geothermal heat exchanger body shakes inevitably when a steel wire rope is wound by a rotating roller, and the geothermal heat exchanger body is not prone to deformation are solved. And along with extension of the steel wire rope, the shaking amplitude of the geothermal heat exchanger body is increased, so that the geothermal heat exchanger body is likely to collide with the well wall, then the clamping jaw is separated from the geothermal heat exchanger body, the geothermal heat exchanger body falls off, and therefore the installation structure is not stable enough, and the danger of falling off is likely to happen.

Description

Technical Field

[0001] The utility model relates to the technical field of geothermal heat exchangers, in particular to a mid-deep underground geothermal heat exchanger which is easy to install. Background Art

[0002] The geothermal heat exchange process is mainly completed through geothermal heat exchangers. During the heat exchange process of geothermal wells, there are two different directions of heat transfer. One is that when the water flow temperature in the pipeline is lower than the rock layer temperature outside the pipeline, the heat is transferred from the rock layer to the fluid. This area mainly exists in the lower part of the downward section, the horizontal section and the lower part of the upward section of the geothermal well; the other is that when the water flow temperature in the pipeline is higher than the rock layer temperature outside the pipeline, the heat is transferred from the fluid to the rock layer. This area mainly exists in the upper part of the downward section and the upper part of the upward section of the geothermal well.

[0003] For example, publication number CN210154120U discloses a horizontally docked well-type medium-deep geothermal heat exchanger, including a bracket installed at the wellhead and a geothermal heat exchanger body located in the well, an iron base is installed on the top of the geothermal heat exchanger body, a first rotating shaft is horizontally arranged on the bracket, a roller is sleeved in the middle of the first rotating shaft, a driving motor is fixedly connected to the bracket on the left side through a support, the right end of the first rotating shaft is fixedly connected to the output end of the driving motor through a coupling, and a counterweight vertical plate is fixedly connected to the roller through a wound wire rope. The utility model can achieve the purpose of lifting the geothermal heat exchanger body to the wellhead by turning on the switch of the driving motor to drive the roller to rotate and reel in the wire rope, and then the geothermal heat exchanger body can be easily and quickly removed from the double insurance fixing mechanism for maintenance, which greatly reduces the difficulty for technicians to repair the geothermal heat exchanger body placed in the deep well.

[0004] Based on the search of patent numbers and combined with the deficiencies in the prior art, it is found that:

[0005] Although this horizontal docking well-type medium-deep geothermal heat exchanger reduces the difficulty for technicians to inspect and repair the geothermal heat exchanger body placed in the deep well, when in use, although the geothermal heat exchanger body is installed more conveniently through the electromagnet and the clamping claw, the roller will inevitably cause the geothermal heat exchanger body to shake when winding the wire rope, and as the wire rope is extended, the shaking amplitude of the geothermal heat exchanger body will increase, making it easy to collide with the well wall, and then cause the clamping claw to separate from the geothermal heat exchanger body, causing the geothermal heat exchanger body to fall, so the installation structure is not stable enough and is prone to falling.
