Background technology
With characteristics environmental protection has received widely energy-conservation because of it of earth-source hot-pump system is used in the last few years, ground pipe laying earth-source hot-pump system be wherein use the most a kind of.The efficient of ground pipe laying earth-source hot-pump system and the hot rerum natura of underground ground have much relations, normally record the hot rerum natura of circulation fluid temperature back analysis ground at present in the engineering according to the scene.But because ground pipe laying diameter is less, can only be on ground the pipe laying import and export record the temperature of circulation fluid, the thermal physical property parameter that obtains of back analysis is the integrated value of multilayer ground thus, can not reflect the characteristics of underground ground layering and seepage flow.
Summary of the invention
For based on the Temperature Distribution of circulation fluid in the ground pipe laying and the thermal physical property parameter of each soil layer of back analysis, the utility model provides a kind of U-shaped pipe laying, and it can detect the vertical Temperature Distribution of circulation fluid in the pipe laying in real time.
The utility model solves the technical scheme that its technical problem adopted: select larger-diameter U-shaped pipe laying, place a cable for measuring temperature within it, cable for measuring temperature connects two arms of whole U-shaped pipe and is positioned at its inboard.Cable for measuring temperature is that tubulose insulation plastic cement cortex encapsulates a plurality of digital temperature sensors and three leads and two wires.Because digital temperature sensor adopts bus mode to link to each other with lead, only need three leads in the cable for measuring temperature, and can make the diameter of cable for measuring temperature be no more than 10mm.Wire in the cable for measuring temperature can adopt the mode stationary digital temperature sensor of epoxy sealing on the one hand, can bear certain pulling force on the other hand, is used for stretching cable for measuring temperature to confirm point for measuring temperature.The insulation plastic cement cortex that wraps up on the cable for measuring temperature can play the effect of waterproof and protection temperature sensor, power supply and steel wire rope.
In addition, design an electro-fusion sleeve with holes, the two ends of sleeve pipe are the electric smelting welding section, and the centre is for the preformed hole section and leave a small diameter bore.Import and export at U-shaped pipe two arms welds electro-fusion sleeve respectively, and through the hole on it cable for measuring temperature is drawn this hole of sealing, tension back.At the other end of two sleeve pipes electric smelting welding water inlet pipe and outlet pipe easily.
Lead in the cable for measuring temperature is linked to each other with temperature data acquisition equipment, can read the temperature of circulation fluid in the pipe laying in real time.
The beneficial effect of the utility model is, can The real time measure U-shaped pipe laying in the vertical Temperature Distribution of circulation fluid, to be used for the hot rerum natura and the percolation flow velocity of underground each rock-soil layer of back analysis.Only need during site operation U-shaped pipe laying 1 and electro-fusion sleeve 3 welding with holes are placed cable for measuring temperature 2 in the U-shaped pipe laying 1, and pass this hole of sealing, electro-fusion sleeve with holes 3 back.
