Arrangement device and arrangement method of subsurface temperature detection sensor of ground source heat pump

Abstract

The invention relates to an arrangement device and arrangement method of a subsurface temperature detection sensor of a ground source heat pump, and belongs to the field of new energy. The device comprises a vertical tube assembly, a straightening mechanism, a transmitting tube nest assembly and multiple temperature measuring and sensing assemblies. The vertical tube assembly is located by the straightening mechanism, it is guaranteed that the vertical tube assembly is relatively stable in heat exchange holes, the transmitting tube nest assembly is arranged on one side of the vertical tube assembly and is perpendicular to the vertical tube assembly, the temperature measuring and sensing assemblies are transmitted into rock soil through the transmitting tube nest assembly, and by means of the above structure, hole stringing caused by dense perforating between the heat exchange holes is avoided. Specifically, the vertical tube assembly comprises a vertical shell and multiple wire guide wheels fixed in the vertical shell, the multiple wire guide wheels can smoothly pull and move wires of the temperature measuring and sensing assemblies, and the wires of the temperature measuring and sensing assemblies are prevented from being wound during transmitting of the temperature measuring and sensing assemblies.

Description

technical field [0001] The invention relates to an arrangement device and an arrangement method of an underground temperature detection sensor of a ground source heat pump, belonging to the field of new energy sources. Background technique [0002] After the construction and backfilling of the ground source heat pump buried pipe system is completed, it is necessary to obtain data on how the temperature of the underground rock and soil changes during operation, and to simulate the temperature gradient of the rock and soil around the heat exchange hole through computer simulation. Because the mathematical model is far from the actual geological situation, it is difficult to accurately reflect the temperature field distribution of the underground rock and soil, and only sensors are placed in the heat exchange holes, which can only reflect the temperature distribution of a single point in the heat exchange holes, and cannot reflect the heat transfer. Geotechnical gradient data a...

Because the mathematical model is far from the actual geological situation, it is difficult to accurately reflect the temperature field distribution of the underground rock and soil, and only sensors are placed in the heat exchange holes, which can only reflect the temperature distribution of a single point in the heat exchange holes, and cannot reflect the heat transfer. Temperature gradient data of rock and soil around the hole

[0003] Drilling holes between the heat exchange holes to lay out the temperature sensing components has the following disadvantages: one is that the drilling cost of the temperature measurement sensor components is high in the middle of the heat exchange holes; The way of laying out the temperature sensing components in the holes determines that only one hole can be drilled between the two heat exchange holes. If two or more holes are to be drilled, the construction is difficult and the verticality of the holes is difficult to guarantee, which may cause the sensor layout to be damaged. Holes and heat exchange holes are intersected to form a string of holes, making it difficult to measure the temperature gradient of rock and soil around the heat exchange holes
