Floating-preventing device for buried pipe of ground source heat pump

Abstract

The invention discloses a floating-preventing device for a buried pipe of a ground source heat pump. The device comprises a mounting plate. A rotating shaft is rotatably inserted onto the mounting plate in a penetrating manner, a driving wheel is fixedly connected to the rotating shaft, threaded rods are symmetrically and rotatably inserted onto the mounting plate in a penetrating manner, driven wheels are fixedly connected to the threaded rods, a transmission belt is arranged between the driven wheels and the driving wheel, threaded sleeves are in threaded connection to the threaded rods, limiting mechanisms are symmetrically arranged on the mounting plate, connecting rods are symmetrically and slidably connected to the bottom side of the mounting plate, drive pipes are fixedly connectedto the connecting rods, and U-shaped pipes are slidably connected to the drive pipes. By connecting the drive pipes to the U-shaped pipes, laying the U-shaped pipes down to a drilled hole with an appointed depth, the threaded sleeves are attached to the ground. Then, by rotating a rotating rod to rotate the rotating shaft to drive the driving wheel to rotate, and by rotating the driven wheels by means of action of the transmission belt to drive the threaded rods to rotate, the threaded sleeves move downward into the ground to fix the device.

Description

technical field [0001] The invention relates to the technical field of ground source heat pumps, in particular to a floating prevention device for buried pipes of ground source heat pumps. Background technique [0002] The ground source heat pump is a device that transfers low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy, etc.) from shallow terrestrial energy. Usually the ground source heat pump consumes 1kwh of energy, and the user can get more than 4kwh of heat or cold. [0003] The ground source heat pump is a heating central air conditioning system composed of a water ground source heat pump unit, a geothermal energy exchange system, and a building system, which uses rock and soil, stratum soil, groundwater or surface water as a low-temperature heat source. According to the different forms of geothermal energy exchange systems, ground source heat pump systems are divided into buried pipe ground sou...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem in the prior art that “it takes a certain amount of time for the backfill to solidify. During this time, the buried pipe will float up under the buoyancy of the backfill, so the depth of the buried pipe will change, affecting to the heat transfer efficiency of ground source heat pumps”, thus a kind of anti-floating device for buried pipes of ground source heat pumps is proposed
