Description
本発明は、深井戸用の水中ポンプと深井戸用手押しポンプを取付けた共用型ポンプ装置の改良に関する。
The present invention relates to an improvement of a shared type pump device equipped with a submersible pump for deep wells and a hand pump for deep wells.
従来、地下水を揚水する手押しポンプには、井戸の水位が８メートル未満の浅井戸用の手押しポンプと、８メートルより深い井戸に使用する深井戸用手押しポンプとがある。しかし、深井戸用に使用される手押しポンプは、ポンプ操作に力が必要であることから浅井戸用手押しポンプのごとく、簡単に揚水することは困難である。そのため、多くの深井戸には、電動で揚水するモーターポンプ（以下、水中ポンプという）が使用されている。
Conventionally, there are two types of hand pumps for pumping up groundwater, one for shallow wells where the water level of the well is less than 8 meters, and one for deep wells used for wells deeper than 8 meters. However, hand pumps used for deep wells are difficult to pump as easily as shallow well hand pumps, because force is required for pump operation. Therefore, motor pumps (hereinafter referred to as submersible pumps) that pump water electrically are used in many deep wells.
また、深井戸用に掘削した井戸は、壁面崩れを防止すると共に保護するためケーシングパイプやスクリーンパイプ（以下、ケーシングパイプという。）が使用されている。このケーシングパイプの内径は、地下水を汲み上げるための水脈に水没させる水中ポンプ、または、手押しポンプのポンプ装置が挿入可能な口径を有するケーシングパイプ、例えば、４～６インチ（約１０～１５ｃｍ）径のものが多く使用されている。
In addition, casing wells and screen pipes (hereinafter referred to as casing pipes) are used for wells excavated for deep wells in order to prevent wall surface collapse and protect them. The inner diameter of the casing pipe is a submerged pump that is submerged in a water vein for pumping up ground water, or a casing pipe having a diameter into which a pump device of a hand pump can be inserted, for example, a diameter of 4 to 6 inches (about 10 to 15 cm). Many things are used.
一方、昨今は災害に備えた自衛意識の高まりや省エネ意識の高まり、または水不足に対応するため、さらには深井戸は地下水が枯渇するおそれが少ないことなどにより、電源を使用しない深井戸用手押しポンプが見直されている。そこで、深井戸用の水中ポンプに深井戸用手押しポンプを取付けて併用するものが知られている（例えば、特許文献１参照）。
On the other hand, in order to respond to the heightened awareness of self-defense and energy conservation in preparation for disasters, or in response to water shortages, deep well push pumps that do not use a power source due to the fact that groundwater is less likely to be depleted. Has been reviewed. Therefore, a deep well submersible pump is known to be used by attaching a deep well hand pump (see, for example, Patent Document 1).
併用型の深井戸ポンプ６４は、図１１に示すごとく、ケーシングパイプ７５内にモーターポンプ６５用の水中ポンプ６６を取付けた揚水パイプ６７と、手押しポンプ用７０のポンプ装置７１を取付けた揚水パイプ７２との２本をそれぞれ挿通して取付けてある。そのため、口径の広い、例えば６インチ（約１５ｃｍ）以上のケーシングパイプ７５を使用した深井戸にしか併用型の深井戸ポンプ６４を取付けることができなかった。
As shown in FIG. 11, the combined type deep well pump 64 includes a pumping pipe 67 in which a submersible pump 66 for a motor pump 65 is mounted in a casing pipe 75 and a pumping pipe 72 in which a pump device 71 for a hand pump 70 is mounted. And are inserted through each of them. For this reason, the combined type deep well pump 64 can be attached only to a deep well using a casing pipe 75 having a large diameter, for example, 6 inches (about 15 cm) or more.
しかし、深井戸用に使用されるケーシングパイプの多くは、経済コストの面から圧倒的に４インチ（約１０ｃｍ）径を有するケーシングパイプが使用されている。そのため、口径の狭い４インチのケーシングパイプに水中ポンプ用の揚水パイプ６７と手押しポンプ用の揚水パイプ７２の二本の揚水パイプを取付けることは不可能であった。
However, most of the casing pipes used for deep wells are casing pipes having a diameter of 4 inches (about 10 cm) overwhelmingly from the viewpoint of economic cost. Therefore, it has been impossible to attach two pumping pipes, that is, a pumping pipe 67 for submersible pumps and a pumping pipe 72 for hand pumps, to a 4 inch casing pipe having a narrow diameter.
本発明は、共用型深井戸ポンプ装置において、手押しポンプ用のポンプ装置７１と、深井戸用の水中ポンプの揚水路を手押しポンプ用のポンプ装置とを纏めて形成し、該ポンプ装置７１と水中ポンプ６６とを垂直方向に位置して取付けることにより、狭い４インチ径の深井戸用ケーシングパイプ内に装着可能に形成することにより、既存する多くの深井戸に取付けることができ、通常は水中ポンプを使用して揚水し、災害時や庭木の水やりなどの省エネ時には手押しポンプを使用して揚水することができるタンデム式手押しポンプを提供する。さらに、従来の深井戸水中ポンプは多くの場合、一般家庭の電力を利用して揚水する水中ポンプを使用しているため、地震などの災害時に停電になると使用できなくなるが、本発明はソーラ―電源を利用し、ソーラパネルからの電力により該深井戸用水中ポンプを利用できるようにした点に特徴を有する。しかし、ソーラ－電源を利用する場合、天候が悪いと効率よく使用できなくなるが、本発明はそのような場合にも、人力により深井戸用手押しポンプを利用できるため、災害に強いポンプを提供するものである。
In the common type deep well pump device, the present invention forms a pump device 71 for a hand pump and a pumping device for the hand pump by collectively forming a pumping channel for the submersible pump for the deep well. By mounting the pump 66 in the vertical direction, it can be mounted in a narrow 4-inch diameter deep well casing pipe, so that it can be mounted on many existing deep wells. To provide a tandem hand pump that can be pumped using a hand pump to save water during a disaster or watering a garden tree. Furthermore, in many cases, conventional deep well submersible pumps use submersible pumps that use ordinary household power to pump water, so they cannot be used if a power failure occurs during a disaster such as an earthquake. It is characterized in that the deep well submersible pump can be used by power from a solar panel using a power source. However, when a solar power source is used, it cannot be used efficiently if the weather is bad, but the present invention provides a pump that is resistant to disasters even in such a case, since a hand pump for deep wells can be used manually. Is.

The upper valve body 58 located in the valve accommodating chamber 54 of the sliding cylinder portion 53 is accommodated in the upper part of the valve seat cylinder 59 attached in the lower end opening of the sliding cylinder portion 53 so as to be movable up and down. The upper valve body 58 moves up and down by the water pressure of the groundwater flowing through the inside and the piston movement of the operating valve body 51 to open and close the valve seat 61.
手押しポンプ４による地下水の吸い上げは、図９、１０に示すごとく、分岐管６の切換弁７を切換えて水中ポンプ１２側を閉口し、手押しポンプ４側を開口する。次いで、手押しポンプ４の作動ハンドル５を操作して複合揚水ユニット１５内のシリンダ筒２８に内蔵したポンプ機構３０により揚水する。ここで弁体１０は、分岐管６の垂直管部６ａ及び揚水パイプ８内に上下方向に挿通したピストン軸９の上部に挿通され、作動ハンドル５が、図７に示すように上方に位置すると、該垂直管部６ａの上端のポンプ弁座８ａを閉口するように装着してある。そして、作動ハンドル５を上方から下げるとピストン軸９が上昇し、前記ポンプ弁座８ａを開口するように構成してある。
As shown in FIGS. 9 and 10, suction of groundwater by the hand pump 4 switches the switching valve 7 of the branch pipe 6 to close the submersible pump 12 side and opens the hand pump 4 side. Next, the operation handle 5 of the hand pump 4 is operated to pump water by the pump mechanism 30 built in the cylinder cylinder 28 in the composite pumping unit 15. Here, the valve body 10 is inserted into the vertical pipe portion 6a of the branch pipe 6 and the upper part of the piston shaft 9 inserted vertically in the pumping pipe 8, and the operation handle 5 is positioned upward as shown in FIG. The pump valve seat 8a at the upper end of the vertical pipe portion 6a is mounted so as to be closed. When the operating handle 5 is lowered from above, the piston shaft 9 is raised and the pump valve seat 8a is opened.
作動ハンドル５を上下に操作してピシトン軸９を介してポンプ機構３０の作動弁体５１を上昇させると、シリンダ筒２８内の下部連結筒３１と作動弁体５１との間に生じた負圧により上部弁体５８は降下して弁座６１を閉口し、下部連結筒３１の下部弁体３４は、負圧により上昇して固定弁座３３を開口する（図６）。
When the actuating handle 5 is operated up and down to raise the actuating valve body 51 of the pump mechanism 30 via the piston shaft 9, the negative pressure generated between the lower connecting cylinder 31 and the actuating valve element 51 in the cylinder cylinder 28. Accordingly, the upper valve body 58 is lowered to close the valve seat 61, and the lower valve body 34 of the lower connecting cylinder 31 is raised by the negative pressure to open the fixed valve seat 33 (FIG. 6).
固定弁座３３が開口すると、地下水は吸込パイプ３８を通って下部連結筒３１の吸込孔３２に入り、弁保持部３５の流入孔３６を通って作動弁体５１と下部連結筒３１との間のシリンダ筒２８内に一定量の地下水が流入する。
When the fixed valve seat 33 is opened, the groundwater enters the suction hole 32 of the lower connection cylinder 31 through the suction pipe 38, and passes between the operation valve body 51 and the lower connection cylinder 31 through the inflow hole 36 of the valve holding portion 35. A certain amount of groundwater flows into the cylinder cylinder 28.
次いで、ピストン軸９を介して作動弁体５１が降下すると、下部連結筒３１の下部弁体３４は、作動弁体５１が降下する圧力で固定弁座３３を閉口し、シリンダ筒２８内の地下水が戻るのを防止すると同時に、作動弁体５１の上部弁体５８がシリンダ筒２８内の地下水の水圧により上昇して弁座６１を開口する。
Next, when the operating valve body 51 is lowered via the piston shaft 9, the lower valve body 34 of the lower connecting cylinder 31 closes the fixed valve seat 33 with the pressure at which the operating valve body 51 descends, and the groundwater in the cylinder cylinder 28 is closed. At the same time, the upper valve body 58 of the operating valve body 51 rises due to the ground water pressure in the cylinder tube 28 and opens the valve seat 61.
作動弁体５１が降下すると、シリンダ筒２８内の水圧により上部弁体５８は押し上げられて弁座６１を開口する。そして、該シリンダ筒内の地下水は摺動筒部５３の弁収容室５４から吸水孔５７を通ってシリンダ筒２８の上方に揚水される。
When the operating valve body 51 is lowered, the upper valve body 58 is pushed up by the water pressure in the cylinder cylinder 28 to open the valve seat 61. The groundwater in the cylinder cylinder is pumped from the valve accommodating chamber 54 of the sliding cylinder portion 53 through the water absorption hole 57 and above the cylinder cylinder 28.
さらに、上下動する作動ハンドル５を下方に押し下げるとピストン軸９は上昇し、作動弁体５１がシリンダ筒２８内を上昇すると、作動弁体５１と下部連結筒３１との間に生じた負圧により作動弁体５１の上部弁体５８は弁座６１を閉口し、下部弁体３４は、下部連結筒３１の固定弁座３３を開口して地下水をシリンダ筒２８内に流入させる。この動作を繰返すことにより、地下水は順次汲み上げられて該シリンダ筒２８から連結筒４４を通過して揚水パイプ８内を通って手押しポンプ４の吐出口Ｎから地下水を流出させることができる。
Further, when the operating handle 5 that moves up and down is pushed downward, the piston shaft 9 rises, and when the operating valve body 51 rises in the cylinder cylinder 28, a negative pressure generated between the operating valve body 51 and the lower connecting cylinder 31 is obtained. As a result, the upper valve body 58 of the operating valve body 51 closes the valve seat 61, and the lower valve body 34 opens the fixed valve seat 33 of the lower connecting cylinder 31 and allows groundwater to flow into the cylinder cylinder 28. By repeating this operation, the groundwater is sequentially pumped up, and can flow out from the discharge port N of the hand pump 4 through the pumping pipe 8 through the connecting tube 44 from the cylinder tube 28.
以下、本発明の実施の形態の作用について説明すると、タンデム式手押しポンプ１は、地下水を汲み上げる揚水パイプ８の上端に、手押しポンプ４と水中ポンプ１２の吐出口Ｍを位置させ、前記揚水パイプ８の下端に複合揚水ユニット１５と水中ポンプ１２を垂直方向に連結して構成してある。
Hereinafter, the operation of the embodiment of the present invention will be described. In the tandem hand pump 1, the discharge port M of the hand pump 4 and the submersible pump 12 is positioned at the upper end of the pump pipe 8 for pumping up ground water, and the pump pipe 8. A composite pumping unit 15 and a submersible pump 12 are connected in the vertical direction to the lower end of each.
したがって、深井戸用のケーシングパイプとして広く普及している４インチ（約１０ｃｍ）径の深井戸に使用することができるので便利である。また、新たに深井戸を掘る場合、径の太いケーシングパイプを使用することなく、径の細い安価な４インチ径のケーシングパイプを使用することができるのでコストが安価で経済的である。
Therefore, it can be used for a deep well having a diameter of 4 inches (about 10 cm) that is widely used as a casing pipe for deep wells, which is convenient. In addition, when a new deep well is dug, an inexpensive 4-inch diameter casing pipe with a small diameter can be used without using a casing pipe with a large diameter, so that the cost is low and economical.
タンデム式手押しポンプ１において、水中ポンプ１２を作動させて揚水する場合、図７に示すごとく、作動ハンドル５を上方に作動してポンプ軸５ａを降下させると弁体１０でポンプ弁座８ａを閉口し、切換弁７を切換操作して水中ポンプ１２側を開口すると手押しポンプ４側は閉回路となる。次いで、水中ポンプ１２を駆動して地下水を揚水口１３から揚水する。
In the tandem hand pump 1, when pumping water by operating the submersible pump 12, as shown in FIG. 7, when the operating handle 5 is operated upward to lower the pump shaft 5 a, the valve body 10 closes the pump valve seat 8 a. When the switching valve 7 is switched to open the submersible pump 12 side, the hand pump 4 side becomes a closed circuit. Next, the submersible pump 12 is driven to pump the groundwater from the pumping port 13.
水中ポンプ１２で揚水された地下水は、複合揚水ユニット１５の水中ポンプ用揚水路Ｘを通って揚水される。水中ポンプ用揚水路Ｘは、図２、８に示すごとく、揚水口１３から水中ポンプ１２の上端に設けた連結筒部１４を通って複合ユニット１５の下端に設けた下部支持筒１７の揚水路１８に送水され、該揚水路から支持リング２１の孔２２を通って外筒１６とシリンダ筒２８との間に設けた流路２７を通り、シリンダ筒２８の上方に揚水され、外筒１６とシリンダ筒２８を連結している連結筒４４の連通口４５から揚水パイプ８を通って吸い上げられて切換弁７を介して水中ポンプ１２の吐出口Ｍから流出する。
The groundwater pumped by the submersible pump 12 is pumped through the submersible pump pumping channel X of the combined pumping unit 15. As shown in FIGS. 2 and 8, the pumping path X for the submersible pump is a pumping path of the lower support cylinder 17 provided at the lower end of the composite unit 15 through the connecting cylinder part 14 provided at the upper end of the submersible pump 12 from the pumping port 13. The water is fed to 18, passes through a hole 22 of the support ring 21 from the pumping passage, passes through a flow path 27 provided between the outer cylinder 16 and the cylinder cylinder 28, and is pumped above the cylinder cylinder 28. It is sucked up through the pumping pipe 8 from the communication port 45 of the connecting tube 44 connecting the cylinder tube 28, and flows out from the discharge port M of the submersible pump 12 through the switching valve 7.
手押しポンプ４を使用する場合は、図９に示すごとく、切換弁７を切り換えて水中ポンプ１２側を閉口して手押しポンプ４側を開口し、手押しポンプ４の作動ハンドル５を上下動させるとポンプ軸５ａとピストン軸９が連動して複合ユニット１５のシリンダ筒２８に内蔵したポンプ機構３０をピストン運動させて地下水を揚水する。
When the hand pump 4 is used, as shown in FIG. 9, the switching valve 7 is switched to close the submersible pump 12 side, the hand pump 4 side is opened, and the operating handle 5 of the hand pump 4 is moved up and down. The shaft 5a and the piston shaft 9 work together to move the piston of the pump mechanism 30 built in the cylinder cylinder 28 of the composite unit 15 to pump up the groundwater.
作動ハンドル５の操作により作動するポンプ機構３０は、図６に示すごとく、作動弁体５１がシリンダ筒２８内を上昇すると、作動弁体５１と下部連結筒３１との間に負圧が生じて作動弁体５１の上部弁体５８が弁座６１を閉口し、下部連結筒３１の下部弁体３４は負圧により上昇して固定弁座３３を開口する。固定弁座３３が開口すると地下水は、下部連結筒３１の吸込孔３２から弁保持部３５の流入孔３６を通って作動弁体５１と下部連結筒３１との間のシリンダ筒２８内に一定量が流入する。
As shown in FIG. 6, the pump mechanism 30 that operates by operating the operation handle 5 causes a negative pressure to be generated between the operation valve body 51 and the lower connecting cylinder 31 when the operation valve body 51 rises in the cylinder cylinder 28. The upper valve body 58 of the operating valve body 51 closes the valve seat 61, and the lower valve body 34 of the lower connecting cylinder 31 rises due to negative pressure to open the fixed valve seat 33. When the fixed valve seat 33 is opened, a certain amount of groundwater passes through the suction hole 32 of the lower connecting cylinder 31 and the inflow hole 36 of the valve holding portion 35 into the cylinder cylinder 28 between the operating valve body 51 and the lower connecting cylinder 31. Flows in.
次いで、作動ハンドル５を上方に移動してシリンダ軸９の下部に連結したに作動弁体５１が降下すると、シリンダ筒２８内に溜った地下水の水圧で下部連結筒３１の下部弁体３４が固定弁座３３を閉口すると同時に、ポンプ軸５ａに取り付けた弁体１０が手押しポンプ４の下部に設けたポンプ弁座８ａを閉口し、揚水パイプ８内の負圧を維持してシリンダ筒２８内の地下水が戻るのを防止すると共に、作動弁体５１の上部弁体５８をシリンダ筒２８内の地下水の水圧により押し上げて弁座６１を開口する。作動弁体５１が降下しながら弁座６１を開口すると、シリンダ筒２８内の地下水は、摺動筒部５３の弁収容室５４から給水孔５７を通ってシリンダ筒２８の上方に揚水される。
Next, when the operating valve body 51 is lowered while the operating handle 5 is moved upward and connected to the lower portion of the cylinder shaft 9, the lower valve body 34 of the lower connecting cylinder 31 is fixed by the water pressure of the groundwater accumulated in the cylinder cylinder 28. Simultaneously with closing the valve seat 33, the valve body 10 attached to the pump shaft 5 a closes the pump valve seat 8 a provided at the lower part of the hand pump 4, and maintains the negative pressure in the pumping pipe 8 to maintain the inside of the cylinder cylinder 28. The ground water is prevented from returning, and the upper valve body 58 of the operating valve body 51 is pushed up by the ground water pressure in the cylinder cylinder 28 to open the valve seat 61. When the valve seat 61 is opened while the operating valve body 51 is lowered, the groundwater in the cylinder cylinder 28 is pumped from the valve storage chamber 54 of the sliding cylinder portion 53 through the water supply hole 57 and above the cylinder cylinder 28.
前記作動弁体５１がシリンダ筒２８内を上昇すると、作動弁体５１と下部連結筒３１との間に生じた負圧で作動弁体５１の上部弁体５８は６１弁座を閉口し、下部弁体３４が下部連結筒３１の固定弁座３３を開口してシリンダ筒２８内に地下水が流入する。この動作を繰返すことにより、地下水は順次汲み上げられてシリンダ筒２８から連結筒４４を通って揚水パイプ８から手押しポンプ４に揚水されて吐出口Ｎから流出させる。
When the operating valve body 51 rises in the cylinder cylinder 28, the upper valve body 58 of the operating valve body 51 closes the 61 valve seat by the negative pressure generated between the operating valve body 51 and the lower connecting cylinder 31, and the lower part The valve body 34 opens the fixed valve seat 33 of the lower connecting cylinder 31 and the groundwater flows into the cylinder cylinder 28. By repeating this operation, groundwater is sequentially pumped up, pumped from the cylinder tube 28 through the connecting tube 44 to the hand pump 4 from the pumping pipe 8, and flows out from the discharge port N.
したがって、手押しポンプ用揚水路Ｙは、図１０に示すごとく、ポンプ機構３０の作用により、外筒１６の下部支持筒１７に設けた吸込口１９から吸込パイプ３８に流入する地下水は、下部連結筒３１の固定弁座３３が開口して吸込孔３２から弁保持部３５の流入孔３６を通ってシリンダ筒２８内に揚水され、作動弁体５１が降下すると、固定弁座３３は下部弁体３４で閉口されてシリンダ筒内の地下水が、開口した作動弁体５１の弁座６１から収容室５４を通って吸水孔５７からシリンダ筒２８の上方に揚水され、さらに上部連結筒４１から連結筒４４と揚水パイプ８を通って手押しポンプ４の吐出口Ｎから吐出する。
Accordingly, as shown in FIG. 10, the hand pump pump pumping path Y is configured so that the groundwater flowing into the suction pipe 38 from the suction port 19 provided in the lower support cylinder 17 of the outer cylinder 16 by the action of the pump mechanism 30 flows into the lower connection cylinder. When the fixed valve seat 33 of 31 is opened and pumped into the cylinder cylinder 28 from the suction hole 32 through the inflow hole 36 of the valve holding portion 35 and the operating valve body 51 is lowered, the fixed valve seat 33 is lowered to the lower valve body 34. The groundwater in the cylinder cylinder is closed from the valve seat 61 of the opened working valve body 51 through the storage chamber 54 through the water receiving hole 57 and above the cylinder cylinder 28, and further from the upper connection cylinder 41 to the connection cylinder 44. And discharged from the discharge port N of the hand pump 4 through the pumping pipe 8.
複合揚水ユニット１５内に水中ポンプ用揚水路Ｘと手押しポンプ用揚水路Ｙをそれぞれ別回路でコンパクトにまとめて形成し、該複合揚水ユニットの下部に水中ポンプ１２を連設し、且つ、前記水中ポンプ用揚水路Ｘと手押しポンプ用揚水路Ｙとを一本の揚水パイプ８に連通させて揚水可能にしたことにより、深井戸用ポンプとして簡単にケーシングパイプに取付けることができるので工事期間が短く安価で経済的である。
A submersible pump pumping channel X and a hand pump pumping channel Y are formed in a separate circuit in a compact manner in the combined pumping unit 15, and a submersible pump 12 is connected to the lower portion of the combined pumping unit, and The pump pumping channel X and the hand pump pumping channel Y are connected to one pumping pipe 8 to enable pumping, so that it can be easily attached to the casing pipe as a deep well pump, so the construction period is short. Inexpensive and economical.
尚、水中ポンプ駆動用の電源は、通常一般家庭用電源を使用するが、災害時など一般家庭用電源が停電になった場合には、ソーラーパネルからの電源を利用できるよう、該水中ポンプの電源接続部に直接、またはソーラ電源用の適宜コネクター（図示せず）を介して接続して使用できるよう、該水中ポンプの電力供給部分にソーラー電源用接続部を設けてある。しかし、天候が曇っている場合は、人力で手押しポンプ４を作動させて地下水を揚水することができるという利点を有するものである。
The power supply for driving the submersible pump is usually a general household power supply. However, in the event of a power outage, such as during a disaster, the submersible pump power supply can be used so that the power from the solar panel can be used. A solar power supply connection portion is provided in the power supply portion of the submersible pump so that the submersible pump can be used by connecting directly to the power supply connection portion or via an appropriate connector (not shown) for solar power supply. However, when the weather is cloudy, it has an advantage that groundwater can be pumped by manually operating the hand pump 4.
