５２０２号公報）。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a circulation type well pump device that circulates pumped well water back to the well through a radiator tube. [Prior Art and Problems of the Present Invention] Pumped well water is passed through a radiator pipe to melt snow on roads, parking lots, roofs, etc., or passed through a radiator pipe for preventing freezing or a radiator pipe for heating, and the water is returned to the same well. Circulation type well pump devices that recirculate water are conventionally known. (Unexamined Japanese Patent Publication No. 53-5
5202).
この従来技術は、同一発明者の発明に係るものであり、
第１図に示す機構を備えたものである。This prior art is related to the invention of the same inventor,
It is equipped with the mechanism shown in FIG.
この従来技術の概略を説明すると次のとおりである。An overview of this conventional technology is as follows.
すなわち、外管３を地中深く埋設し、この外管に吸上げ

いる。That is, the outer pipe 3 is buried deep underground, the suction pipe 2 is installed inside the outer pipe, the submersible pump 6 is connected to the upper end of the suction pipe 2, and the discharge pipe 9 of the submersible pump is connected to the airtight lid 8. This seal M8 is fixed to the flange 3' at the upper end of the outer tube.

戻り管１７．バルブ１６、外管３の枝管１４を通して外
管３に環流させ、外管３と吸上げ管２との間を通して再
び地下に押し込む。The groundwater that has flowed into the outer pipe buried deep underground is pumped up by the pump 6 through the suction pipe 2, and then pumped up through the discharge pipe 9. The water is sent to the water pipe through the check valve 11 and the valve 12, and the heat radiation pipe 18.
Return pipe 17. The water is returned to the outer pipe 3 through the valve 16 and the branch pipe 14 of the outer pipe 3, and then passed between the outer pipe 3 and the suction pipe 2 and pushed underground again.
以上の従来技術においては、ポンプ６の保守のためにポ

水を汲み上げるためには、相当の長さの吸い上げ管が必
要であるので、吸上げ管２を外管から引き抜く作業は容
易なことではない。In the above conventional technology, when the pump 6 is pulled up for maintenance, it must be pulled out from the outer pipe together with the suction pipe 2. In order to pump up groundwater at a temperature higher than that required for snow melting, a considerable amount of water is required. Since a long suction tube is required, it is not easy to pull out the suction tube 2 from the outer tube.
従来技術において吸上げ管２を外管に固定させず、吐出
管９に固定して支持させているのは、吸上げ管２の上端

封するとともにこの完全密封状態を長期間維持すること
が困難であるからである。In the conventional technology, the suction pipe 2 is not fixed to the outer pipe, but is fixed and supported by the discharge pipe 9. If the upper end of the suction pipe 2 is not completely sealed, outside air will be sucked in from the upper end, and underground water will be drawn in. This is because it is difficult to completely seal the upper end of the suction tube and maintain this completely sealed state for a long period of time with a structure in which the suction tube is fixed to the outer tube. be.

きるようにすることをその技術的課題とするものである
。One object of the present invention is to facilitate the sealing of the upper end of the suction pipe and to facilitate the maintenance of this seal, in contrast to the conventional structure in which the suction pipe is supported by the outer pipe and the pump is separated from the suction pipe. The technical objective is to easily maintain complete sealing for a long period of time.

的に抑制するために、伝熱性の小さいものが好ましい。The outer casing pipe 22 is preferably one with high heat conductivity so that the water returned into the outer casing vibe can absorb more geothermal heat while descending, but usually a steel pipe is used. As for the inner casing pipe, it is preferable to use one with low heat conductivity in order to suppress as much as possible the warm underground water flowing upward therein from being cooled by the cold return water flowing downward within the outer casing pipe 22. .

事量は。The fact that the problems of the prior art mentioned above are solved is itself an effect unique to the present invention. In addition, the water head pressure inside the inner casing pipe (corresponding to the "suction pipe" in the prior art section) is approximately equal to the water head pressure in the outer casing pipe (corresponding to "outer pipe J" in the prior art section), and The head pressure of the casing pipe is the return pipe 31.
is equal to the return pressure by , so the work done by pump 24 is .

利点である。This corresponds to the pressure loss due to pipe resistance throughout the system. Therefore, the power consumption for this pump work is extremely small compared to the amount of water of 1wJ.This means that the outer casing pipe and the inner casing pipe are sealed with a top plate and a lid plate to form a sealed pipe. This is a major advantage because the groundwater circulation system is basically a closed circuit. Furthermore, related to this, there is no need to lower the position of the pump 24 to a deep position, and the length of the pumping pipe 25 (corresponding to the "discharge pipe" in the prior art section) can be short. Another major advantage is that removal from the inner casing pipe and insertion into the inner casing pipe are extremely simple and easy.
