Problems solved by technology

The outer well pipe is provided with a contact surface and an isolation structure that cooperates with the outer wall of the inner well pipe. Only when the lengths of each contact section are exactly the same can they maintain a sealed connection with each other, but it is actually difficult to achieve the purpose of all sealed connections
Since the depth of the well is usually hundreds of meters, the outer well pipe and the inner well pipe are welded separately. After the inner and outer well pipes are lowered into the well, the displacement or welding errors are relatively large, and the corresponding standards are not uniform, which leads to the contact between the inner well pipe and the outer well pipe. Poor sealing performance
Since the sealing and docking process takes place in the underground, it is in a blind spot, and cannot be maintained by people, so it is difficult to grasp the connection effect and sealing effect, and the submersible pump in the future will be time-consuming and labor-intensive, which will affect the use of the air conditioner for a long time

Embodiment 1

[0032] Among them, such asfigure 1 As shown, the inner well pipe and the outer well pipe are composed of multi-section units, which are respectively: well pipe section unit, isolation section unit, wellhead unit and well bottom unit.

[0033] 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 section unit body and the well pipe section unit body is fitted together through the plug and the casing seat 2, and the adjacent mesh type well pipe section 5 is welded (or bolt or buckle). connected) fixed together. The water outlet pipe 17 is located in the well pipe after the inner assembly is butted. In this embodiment, the ...

Embodiment 2

[0041] Embodiment 3: On the basis of Embodiment 1, the well pipe unit is modified. like 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.

Embodiment 3

[0042] Embodiment 4: On the basis of Embodiment 1, the unit body of the isolation section is modified. like Figure 8 and Figure 9 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.

Abstract

The invention discloses an inside-outside integral docking type same-well pumping and recharging device for a water source well of a water source heat pump type central air conditioning. The inside-outside integral docking type same-well pumping and recharging device comprises the water source well, a well lid, an inner well pipe, an outer well pipe, a water outlet pipe, a water return pipe and a water suction pump. Each of the inner well pipe and the outer well pipe is in a multi-unit combined structure and comprises a well pipe unit, an isolation unit, a wellhead unit and a well bottom unit. The inside-outside integral docking type same-well pumping and recharging device has the advantages that industrial manufacturing and processing can be realized to achieve unification and standardization of product specifications, the problem of inside-outside axial misplacement is avoided, operability of hermetic connection is guaranteed, and hermetic docking quality is improved; quickness and accuracy in onsite positioning and construction are benefited; troubles of checking after installation are avoided, the problem of possibility of poor docking tightness after installation is avoided as well, pipe mounting speed is increased by at least one time, and time consumed for subsequent maintenance and submersible pump replacement is shortened from 3-4 days to 7-8 hours.

Description

technical field [0001] The invention relates to the problem of water source well recharge and recharge water cooling and heat exchange in the technical field of water source heat pump central air-conditioning, in particular to a water source heat pump central air-conditioning water source well whose inner and outer pipes are integrally sealed and docked with the well outlet and return water device. Background technique [0002] The water source heat pump central air conditioner is a central air conditioner that uses groundwater with a constant temperature for many years as the medium. Through the heat pump unit, the water temperature is raised or lowered to achieve the purpose of cooling and heating, and to provide cold and heat sources for buildings. Because of its high energy efficiency ratio, it saves 40-60% energy compared with other traditional forms of central air conditioners, and has a remarkable effect of energy saving and consumption reduction. It is gradually favor...
