Solar cross-season soil embedded pipe heat storage and supply device

The utility model discloses a solar cross-season soil embedded pipe heat storage and supply device, which comprises a solar heat collector, a water tank and a solar heat supply and exchange coil pipe. A ground source heat pump heat exchange coil pipe is arranged in the water tank and communicated with a plate heat exchanger through a second circulating pipeline, wherein the second circulating pipeline is provided with a second water pump, a first constant pressure tank and an electromagnetic valve; the plate heat exchanger is communicated with a heat pump unit through a third circulating pipeline, and the third circulating pipeline is provided with a third water pump, a third constant pressure tank and an electromagnetic valve; and the plate heat exchanger is also communicated with an underground embedded pipe embedded underground and provided with an underground heat insulation device through a fourth circulating pipeline, wherein the fourth circulating pipeline is provided with a fourth water pump, a second constant pressure tank and an electromagnetic valve. The device can store the redundant heat generated by a summer solar heat collecting system for use in winter, effectively save the energy, improve the use efficiency of the solar energy, and meanwhile overcome the defect of the traditional ground source heat pump.
