Pipeline equipment for soil ground source heat pump

Abstract

The invention relates to the technical field of ground source heat pumps, and discloses pipeline equipment for a soil ground source heat pump. The pipeline equipment comprises a pipeline, a detectionblock is inserted into the side surface of the pipeline, detection plates are inserted into the side surface of the detection block, and push rods are arranged on the opposite sides of the two detection plates. Arc-shaped rods are rotatably connected to the sides, away from the detection plates, of the push rods, rollers are connected to the surfaces of the arc-shaped rods in a rolling mode, supporting springs are arranged on the side faces of the arc-shaped rods and located above the rollers, a guide pipe is fixedly connected to the left side of a transition air bag, and a one-way toothed rodis fixedly connected to the side face of an air plate. The side face of the one-way toothed bar is connected with a limiting toothed plate in an engaged mode. According to the pipeline equipment forthe soil ground source heat pump, through cooperative use of the detection plates and liquid blocking wheels, the effect that when the tightness degree of connection between the pipeline and soil is reduced, the tightness degree of the pipeline and the soil is automatically reinforced, and heat conduction is prevented from being affected is achieved.

Description

technical field [0001] The invention relates to the technical field of ground source heat pumps, in particular to pipeline equipment for soil ground source heat pumps. Background technique [0002] 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) from shallow land energy. Usually, ground source heat pump consumes 1kWh of energy, and users can get more than 4.4kWh of heat or Cooling capacity, in addition, the concept of ground source heat pump was first proposed by Swiss experts in 1912, and the proposal of this technology began in Britain and the United States. [0003] In the actual use of ground source heat pumps, it is necessary to bury the pipes in the outdoor soil and form a circulation with the indoor heat pump unit, and the pipes buried outdoors need to be fully in contact with the soil to maximize heat transfer. When rainwater infiltrates into...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a pipeline equipment for soil ground source heat pumps, which has the advantages of automatically reinforcing the tightness of the connection between the pipeline and the soil to avoid affecting heat conduction when the tightness of the connection between the pipeline and the soil decreases, and solves the problem of Currently, when rainwater infiltrates into the junction between the pipe and the soil, the rainwater will scour the soil at the junction, which will lead to a decrease in the tightness of the connection between the soil and the pipe, and adversely affect the heat conduction between the pipe and the soil.
