Abstract
The utility model discloses a wellhead sealing structure of a mining and irrigating system of an underground water source heat pump. The wellhead sealing structure comprises a flange and a flange cover, wherein the flange is welded at a wellhead; the flange cover is matched with the flange for use and is provided with a plurality of preassembling holes; a water drawing pipe, a submersible pump cable and a water thermometer cable penetrate through the preassembling holes from the inner part of the wellhead to the outer part of a well; the top end of the flange cover is also provided with a vacuum meter and a pressure meter for detecting the conditions in the well; and a manual exhaust valve is arranged at the wellhead. The wellhead sealing structure disclosed by the utility model has the beneficial effects that the structure is simple, the design is ingenious, a reasonable sealing scheme is provided, and simultaneously the air tightness and the re-irrigation state of an underground water system also can be effectively monitored.
Description
Technical field
The utility model relates to the ground water regime technical field, specially refers to a kind of groundwater heat pump and adopts fill system well head hermetically-sealed construction and detection method thereof.
Background technology
Groundwater heat pump air-conditioning system difficult point is phreatic recharging.If it is bad that well is handled, inverted well will can't reach the amount of recharging, some Yangtze River Delta Area such as Shanghai because of impurity stops up; The water quality ferromanganese ion content in second water-bearing layer of the degree of depth about 100m is big; With can very fast oxidation after air contacts and produce deposition, the deposit of generation is easy to stop up well casing considers net and causes the groundwater recharge ability drop, so if there is air to get in the ground water regime; If things go on like this will influence groundwater recharge even cause well to be scrapped; In case underground water well can not normally use, entirely descend water source heat pump air conditioning system also will can't use because losing Cooling and Heat Source, lose huge.
The difficult point of ground water regime sealing with the sealing technique of well head.The making of pipeline can be accomplished watertight; But wellhead equipment is complicated; Drinking-water pipe, recharge pipe, immersible pump and sensor cable etc., all need pick out, so sealing is not easy especially just from well head; Not only to design rational closure solutions, but also will have effective surveillance and control measure to check the air-tightness of ground water regime at any time and recharge state.
In sum, to the defective of prior art, need a kind of groundwater heat pump to adopt fill system well head hermetically-sealed construction and detection method thereof especially, with the problem of mentioning more than solving.
The utility model content
The purpose of the utility model is to provide a kind of groundwater heat pump to adopt fill system well head hermetically-sealed construction and detection method thereof,
The technical problem that the utility model solved can adopt following technical scheme to realize:
A kind of groundwater heat pump is adopted fill system well head hermetically-sealed construction; It is characterized in that; Comprise the flange and the blind flange matching used with it that are welded in well head, said blind flange is provided with some prepackages hole, and drinking-water pipe, submersible pump cable and water level thermometer cable pass the prepackage hole and extend to outside the well from well head inside; On the top of blind flange vacuum meter and the Pressure gauge that is used to detect situation in the well is installed also, the place is provided with manual exhaust valve at well head.
In an embodiment of the utility model; Said submersible pump cable and water level thermometer Seal of Cables mounting structure comprise bolt, nut and rubber ring; Said nut is welded in the top in blind flange cable prepackage hole; Be provided with the rubber blanket with the identical bore of nut in the hole in prepackage, bolt passes nut and compresses rubber blanket.
The beneficial effect of the utility model is: simple in structure, design ingeniously, and a kind of rational encapsulation scheme is provided, air-tightness that simultaneously can also effective monitoring ground water regime and recharge state.
Description of drawings
Fig. 1 adopts the profile of fill system well head hermetically-sealed construction for the described groundwater heat pump of the utility model.
Fig. 2 adopts the vertical view of fill system well head hermetically-sealed construction for the described groundwater heat pump of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.
As depicted in figs. 1 and 2; The described a kind of groundwater heat pump of the utility model is adopted fill system well head hermetically-sealed construction; Comprise the flange 7 and the blind flange matching used 6 that are welded in well head with it; Said blind flange 6 is provided with some prepackages hole; Drinking-water pipe 1, submersible pump cable 2 and water level thermometer cable 12 pass the prepackage hole and extend to outside the well from well head inside, the vacuum meter 10 and Pressure gauge 11 that are used to detect situation in the well also are installed on the top of blind flange 6, are provided with manual exhaust valve 13 at the well head place.
The sealing mounting structure of said submersible pump cable 2 and water level thermometer cable 12 comprises bolt 3, nut 4 and rubber ring 5; Said nut 4 is welded in the top in blind flange 6 cables prepackage hole; Be provided with the rubber blanket 5 with nut 4 identical bores in the hole in prepackage, bolt 3 passes nut 4 and compresses rubber blanket 5.
It is following that the described groundwater heat pump of the utility model is adopted the installation method of fill system well head hermetically-sealed construction:
Underground water well Cheng Jinghou at the well head flange of burn-oning, reserves the hole and the bolt hole of drinking-water pipe caliber on blind flange, the aboveground part of drinking-water pipe is connected with blind flange with the down-hole part, blind flange is installed on the flange that well head welds again.Blind flange also must be reserved submersible pump cable, water level thermometer cable, vacuum meter, Pressure gauge and manual exhaust valve installation position before installation.The sealing of submersible pump cable is installed, and gets the bolt of the suitable size of a cover, on bolt, bolt is from first to last got through the hole; Nut is welded in blind flange cable preformed hole top, is encased inside the installation site after getting the rubber blanket punching of the identical bore of nut, all opening diameters for cable just through being advisable; After cable is worn from well inside to well through hole; Bolt is screwed in the nut base, and expand in the compacted back of rubber blanket, with preformed hole and cable seal; Water level thermometer cable same procedure is installed, and at well head vacuum meter, Pressure gauge and manual exhaust valve is installed at last.
A kind of groundwater heat pump is adopted the detection method of fill system well head sealing property, and said method comprises the steps:
1) when recharging, open manual exhaust valve,, well water is full of water to drain air in the explanation well when spraying, and this moment, valve-off was noted the pressure on the Pressure gauge;
2) continue to recharge a period of time after, if Pressure gauge pressure rises, explain that then inverted well has clogging, the cleaning of need taking measures is considered net;
3) when recharging when stopping, the water level in the well casing is because gravity effect meeting descends, and can produce vacuum in the well this moment, on vacuum meter, can read vacuum, and when vacuum had obvious declines at short notice, illustrative system had leakage repairing at once.
The beneficial effect of the utility model is: simple in structure, design ingeniously, and a kind of rational encapsulation scheme is provided, air-tightness that simultaneously can also effective monitoring ground water regime and recharge state.
