Embodiment 1
[0032] Embodiment 1: The first kind of water source heat pump central air conditioning water source well with integrated inner and outer pipes and well outlet and return water device, including water source well and well cover 18, inner well pipe and outer well pipe, outlet pipe 17, return pipe 16 and submersible pump 11 and so on.
[0033]Among them, such as figure 1 As shown, the inner well pipe and the outer well pipe are a structure composed of multi-segment units, which are respectively: well pipe unit, isolation unit, wellhead unit and well bottom unit.
[0034] The well pipe section unit body in this embodiment is as follows figure 2 , including the inner well pipe section 1 and the mesh type well pipe section 5, both of which are coaxially fixed together by connecting pieces 6. One end of each inner well pipe section 1 is provided with a casing seat 2, and the other end is provided with a plug. Therefore, the inner well pipe section 1 between the adjacent well pipe...
Embodiment 2
[0041] Embodiment 2: On the basis of Embodiment 1, the well pipe unit is modified. Such as Figure 5 As shown, the inner well pipe section contains the part of the plug, and its diameter is smaller than that of the inner well pipe section to form a shrinkage pipe section 9, and the plug is located at the end of the shrinkage pipe section 9.
Embodiment 3
[0042] Embodiment 3: On the basis of Embodiment 1, the well pipe unit is modified. Such as Figure 6 and Figure 7 As shown, plugs or casing seats 2 are provided at both ends of the inner well pipe section, and casing seats 2 or plugs are provided at both ends of the adjacent inner well section matched with it.
