A kind of shallow layer geothermal energy underground buried tube system structure, comprising the following steps:
The first step accesses cold water by water inlet pipe 5, and water pump 9 starts, if the first temperature sensing 19 and second temperature sensor 27
Interior temperature value carries out numerical value comparison by sensing main body 21, and when difference is lower than 5 DEG C, while three-way magnetic valve 30 flows to efferent duct
31 one end is closed, and the one end for flowing to return pipe 29 is opened, meanwhile, anti-blocking motor 12 works, and drives anti-16 swivel plate 17 of blocked shot
It is rotated, so that the ice cube in water inlet pipe be made quickly to remove, flows water flow, under the action of water pump 9, water flow is by water inlet
Pipe 5, heat energy utilization pipe 6, outlet pipe 8 and return pipe 29 form water flow circuits, at this time the temperature of second temperature sensor measured
Value is gradually higher than the first temperature sensor;
Second step, after the water in water flow circuits is full, water inlet pipe 5 does not reinject cold water, thus what the first temperature sensor measured
Temperature value increases, when the temperature value difference zero that the first temperature sensor 19 and second temperature sensor 2 measure, anti-blocking motor
12 stop working, and three-way magnetic valve 30 flows to one end opening of efferent duct 31, and the one end for flowing to return pipe 29 is closed, to make
Hot water is smoothly discharged;
Third step is arranged temperature in outlet pipe 8 by control main body 22, sets when the temperature that second temperature sensor 27 measures is lower than
Temperature is set, control main body 22, which controls the flap movement in flow valve 28, makes 28 bore of flow valve become smaller, to make geothermal energy utilization
Pipe 6 reduces to the flow that outlet pipe 8 flows out hot water, while controlling the control frequency converter 26 of main body 22 reduces the power of water pump 9, from
And the time for flowing through water flow in geothermal energy utilization pipe 6 lengthens, geothermal energy is also just longer to the heat transfer time of water, and temperature rises,
When the temperature that second temperature sensor 27 measures is higher than setting temperature, control main body 22, which controls the flap movement in flow valve 28, to be made
28 bore of flow valve becomes larger, so that the flow for making geothermal energy utilization pipe 6 flow out hot water to outlet pipe 8 increases, while controlling main body
22 control frequency converters 26 increase the power of water pump 9, so that the time for flowing through water flow in geothermal energy utilization pipe 6 shortens, underground heat
Can heat transfer time to water it is also just shorter, temperature decline is adjusted, repeatedly so that leaving water temperature is identical as set temperature.
