Abstract
The invention discloses an automatic switching system for ground source heat pump groundwater exploitation and recharging wells. The automatic switching system comprises a plurality of deep wells, deep well submersible pumps and a heat exchanger, wherein the deep well submersible pumps are arranged below water levels in the deep wells; the heat exchanger is connected with the deep well submersible pumps through connecting pipelines. The automatic switching system is characterized in that exploitation and recharging switching devices are vertically arranged on the connecting pipelines, and each exploitation and recharging switching device comprises a valve body and a valve element, wherein a longitudinal runner and a transverse runner are formed in the valve body, and are communicated mutually; each rotatable valve element is arranged on one side of a joint of the corresponding longitudinal and transverse runners; the size and shape of each valve element are matched with those of the corresponding longitudinal and transverse runners. The automatic switching system has the beneficial effects that the deep exploitation and recharging wells can be switched for running under the condition of no increase of system investment and maintenance cost, a strainer pipe is effectively prevented from being clogged, and the service life of each deep well is prolonged.
Description
Technical field
The present invention relates to underground water heat pump air conditioner technical field, specially refer to the underground hydromining of a kind of earth source heat pump and fill with the well automatic switchover system.
Background technology
Ground water heat pump air-conditioning system is more and more used in case history with the characteristic of its energy-conserving and environment-protective.Thus, the operation that just directly has influence on whole air-conditioning system as the result of use of the deep-well of ground water heat pump air-conditioning system core and life-span.In case deep-well is because use and maintenance is improper scraps in advance, so a whole set of air-conditioning system also will be owing to Cooling and Heat Source can't be supplied with and can not use, very huge of the loss that brings.The at present maintenance of deep-well is except regular Hui Yang, immersible pump inspection and examination of water, and the method in the easiest and effective prolongation well service life is exactly regularly to adopt the exchange of filling with well to move.That is to say, if 3 mouthfuls of deep-wells of certain requirement of engineering, 1 adopts 2 fills with, and 3 mouthfuls of wells need to be adopted the use of filling by turns during system's operation so, and such as first cycle of operation, No. 1 well is adopted, 2, No. 3 well irrigation; The so next cycle of operation just changes into, and No. 2 well is adopted, 1, No. 3 filling; Next again, No. 3 well is adopted, 1, No. 2 filling.Doing like this dredging that is conducive to filter pipe prevents from stopping up.
As shown in Figure 5, A adopts when deep-well, when deep-well B fills with, and Open valve 7,10, valve-off 8,9, this moment, deep-well A immersible pump just entered deep-well B by recharging pipe after drawing up next water process heat exchanger; Otherwise, Open valve 8,9 then, valve-off 7,10.Because the immersible pump delivery port has check-valves (check-valves is used for stoping the whereabouts protection water pump blade of water in the pipe when termination of pumping), enters in the well from recharging pipe so recharge to switch by valve.This way has increased undoubtedly adopts the workload of filling with when switching, and must operate manually when transposing, and the deep-well spacing is often distant again, operates very inconvenient.If adopt electrically operated valve to switch, the first, increased the cost of investing; The second, many electrically operated valves have increased again the cost of system maintenance.
In sum, for the defective of prior art, need especially the underground hydromining of a kind of earth source heat pump to fill with the well automatic switchover system, to solve above-mentioned problem.
Summary of the invention
The object of the present invention is to provide the underground hydromining of a kind of earth source heat pump to fill with the well automatic switchover system, adopt the filling switching device shifter by in water lines, increasing, thereby realize purpose of the present invention.
Technical problem solved by the invention can realize by the following technical solutions:
The underground hydromining of a kind of earth source heat pump is filled with the well automatic switchover system, comprise some deep-wells, the heat exchanger that is arranged at the deep well submerged pump under the water level of deep well and links to each other with described deep well submerged pump by connecting line, it is characterized in that, be provided with on the described connecting line adopt vertically install adopt the filling switching device shifter;
The described filling switching device shifter of adopting comprises valve body and spool, vertical runner and transverse flow channels that the valve inner setting is interconnected, side in described vertical runner and transverse flow channels junction is installed rotating spool, and the size of the size shape of described spool and vertical runner and transverse flow channels matches.
Beneficial effect of the present invention is: in the situation that not increase system investment and maintenance cost, realized that deep-well adopts the exchange of filling with well and move, effectively prevented the obstruction of filter pipe, prolonged the service life of deep-well.

The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
As depicted in figs. 1 and 2, the underground hydromining of a kind of earth source heat pump of the present invention is filled with the well automatic switchover system, comprise deep-well 1 and 2, the heat exchanger 5 that is arranged at the deep well submerged pump 3 under the water level of deep well and links to each other with described deep well submerged pump 3 by connecting line, it is characterized in that, be provided with on the described connecting line and adopt adopting of vertically installing to fill with switching device shifter 4;
The described filling switching device shifter 4 of adopting comprises valve body 41 and spool 42, vertical runner and transverse flow channels that the valve inner setting is interconnected, side in described vertical runner and transverse flow channels junction is installed rotating spool, and the size of the size shape of described spool and vertical runner and transverse flow channels matches.
As shown in Figure 3, deep well submerged pump is extracted underground water out, and current produce a pressure P to spool at this moment, thereby sealed transverse flow channels from bottom to top.
As shown in Figure 4, fill with switch when recharging state when adopting, current from the top down, make spool that end opening is sealed bypass to the pressure P of spool and open, realized recharging, made things convenient for and adopted the switching of filling with well this moment.
Beneficial effect of the present invention is: in the situation that not increase system investment and maintenance cost, realized that deep-well adopts the exchange of filling with well and move, effectively prevented the obstruction of filter pipe, prolonged the service life of deep-well.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
