　ところで、上記土壌測定装置では、土壌（粘性体）の例えば湿度は測定できるが、その測定地点の土壌の水位情報を取得することはできない。水田等のように水と泥が積層された積層体の所定地点の水位及び泥の温度を測定する場合には、上記土壌測定装置とは別に水位情報を取得する水位測定装置も設置する必要がある。したがって、使用する測定装置の数も多くなり、測定装置の取り扱い及び管理が煩雑となる。 By the way, in the above soil measuring apparatus, for example, the humidity of the soil (viscous body) can be measured, but the water level information of the soil at the measurement point cannot be acquired. When measuring the water level and mud temperature at a predetermined point of a laminated body in which water and mud are laminated, such as paddy fields, it is necessary to install a water level measuring device that acquires water level information separately from the soil measuring device. is there.

　本発明はかかる事情に鑑みてなされたものであり、その目的は、液体が粘性体上に積層された積層体の所定地点の液体の水位と粘性体の温度を測定するとき、水位及び温度の測定データを簡単に取得することができるとともに、使用する測定装置の削減を図ることができる水位温度測定装置を提供することにある。 The present invention has been made in view of such circumstances, and its purpose is to measure the water level and temperature when measuring the liquid level and the temperature of the viscous body at a predetermined point of the laminated body in which the liquid is laminated on the viscous body. An object of the present invention is to provide a water level temperature measuring device that can easily acquire measurement data and can reduce the number of measuring devices to be used.
　上記の目的を達成するために、本発明の水位温度測定装置は、液体が粘性体上に積層された積層体における前記液体の水位と前記粘性体の温度を測定する水位温度測定装置であって、前記積層体に設置されるセンサユニットを有し、前記センサユニットの上部側に前記液体の水位を測定するための水位センサが少なくとも一つ搭載されるとともに、下部側に前記粘性体の温度を測定するための温度センサが少なくとも一つ搭載されていることを特徴とする。 In order to achieve the above object, a water level temperature measuring device according to the present invention is a water level temperature measuring device for measuring a liquid level in a laminate in which a liquid is laminated on a viscous material and a temperature of the viscous material.

At least one temperature sensor for measurement is mounted.
　この構成によれば、液体が粘性体上に積層された積層体の所定地点の液体の水位と粘性体の温度を測定するとき、一つの測定装置で水位と温度を同時に測定することができるので、水位と温度の測定データを簡単に取得することができ、且つ使用する測定装置の削減を図ることができる。 According to this configuration, when measuring the liquid level and the temperature of the viscous body at a predetermined point of the laminated body in which the liquid is laminated on the viscous body, the water level and the temperature can be measured simultaneously with one measuring device. The water level and temperature measurement data can be easily obtained, and the number of measuring devices to be used can be reduced.
　好適には、本発明は、前記センサユニットは筒状の筐体内に組み込まれ、前記筐体には前記液体が前記水位センサの搭載位置に流入する液体流入口が形成されるとともに、前記粘性体が前記温度センサの搭載位置に流入する粘性体流入口が形成されていることを特徴とする。
　この構成によれば、筐体内に組込まれている水位センサの搭載位置に液体がスムーズに流れ込むとともに、温度センサの搭載位置に粘性体がスムーズに流れ込む。したがって、積層体の液体の水位及び粘性体の温度を簡単かつ精度よく測定することができる。
　また、筐体が筒状に形成されているので、筐体を抵抗なくスムーズに粘性体に差込み、そして埋め込むことができるので、筐体内に組込まれている水位センサ及び温度センサの損傷を防ぐことができる。 Preferably, in the present invention, the sensor unit is incorporated in a cylindrical casing, and the casing is formed with a liquid inflow port through which the liquid flows into the mounting position of the water level sensor.

According to this configuration, the liquid smoothly flows into the mounting position of the water level sensor incorporated in the casing, and the viscous material smoothly flows into the mounting position of the temperature sensor. Therefore, the liquid level of the laminated body and the temperature of the viscous body can be measured easily and accurately.

　好適には、本発明は、前記温度センサは前記センサユニットの深さ方向に所定間隔をおいて２個配置されていることを特徴とする。
　この構成によれば、粘性体の温度を測定するとき、温度センサの一方が故障しても、他方の温度センサで継続して温度測定を行うことができるので、温度センサが故障する毎に水位温度測定装置を積層体から取り外す必要はなく、水位温度測定装置の取り扱いを簡単に行える。
　また、粘性体の温度を粘性体の層の深さ方向の２箇所で測定することができるので、所定地点における粘性体の温度を正確に測定することができる。 Preferably, the present invention is characterized in that two temperature sensors are arranged at a predetermined interval in the depth direction of the sensor unit.

　筐体２内は水位センサ３２が配置される上部領域４と第１温度センサ３４及び第２温度センサ２５が配置される下部領域５に区分けされている。 (Casing)
The housing 2 is divided into an upper region 4 in which the water level sensor 32 is disposed and a lower region 5 in which the first temperature sensor 34 and the second temperature sensor 25 are disposed.
　筐体２の上部側には水田５０の泥５２の層への埋め込み深さを規定する傘部６が一体形成されている。傘部６は円盤状の底板部７を有し、底板部７の中央部分に筐体２が差し込まれた構成となっている。底板部７の外周には円環状の側板部８が上方に突出するように形成されている。側板部８には周方向に等間隔をおいて複数の側板側水連通口８Ａが形成されている。底板部７の上面には円環状の側板部８が歪まないように４枚の補強板７Ａが周方向に等間隔をおいて形成されている。底板部７の下面７Ｅと筐体２の外周面との間には、傘部６が筐体２に対して位置ずれを起こさないように４枚の三角形状の補強板７Ｂが筐体２の周方向に等間隔をおいて形成されている。 On the upper side of the housing 2, an umbrella portion 6 that defines the depth of padding 50 in the mud 52 layer is integrally formed. The umbrella part 6 has a disk-shaped bottom plate part 7, and the housing 2 is inserted into the central part of the bottom plate part 7. An annular side plate 8 is formed on the outer periphery of the bottom plate 7 so as to protrude upward. A plurality of side plate side water communication ports 8 </ b> A are formed in the side plate portion 8 at equal intervals in the circumferential direction. Four reinforcing plates 7A are formed on the upper surface of the bottom plate portion 7 at equal intervals in the circumferential direction so that the annular side plate portion 8 is not distorted. Between the lower surface 7E of the bottom plate portion 7 and the outer peripheral surface of the housing 2, four triangular reinforcing plates 7B are provided on the housing 2 so that the umbrella portion 6 does not shift relative to the housing 2. It is formed at equal intervals in the circumferential direction.
　傘部６の底板部７の上面から上側に突出する筐体２の基端部分には、筐体２内の上部領域４に水田５０の水５１を流し込むための液体流入口となる第１水流入口２Ａ及び第２水流入口２Ｂ（図７を参照）が筐体２の径方向に対向して形成されている。 A first water flow serving as a liquid inlet for pouring the water 51 of the paddy field 50 into the upper region 4 in the housing 2 at the base end portion of the housing 2 protruding upward from the upper surface of the bottom plate portion 7 of the umbrella portion 6. An inlet 2 </ b> A and a second water inlet 2 </ b> B (see FIG. 7) are formed facing the radial direction of the housing 2.

　筐体２を水田５０の泥５２の層へ埋め込み、そして傘部６の底板部７の下面７Ｅが水田５０の泥５２の層の表面５２Ａに当接すると、傘部６の底板部７には泥５２の層の抵抗が加わる。そうすると、筐体２をそれ以上泥５２の層へ埋め込むことができなくなり、筐体２の泥５２の層への埋め込み深さが規定される。すなわち、筐体２を泥５２の層に埋め込み、傘部６の底板部７の下面７Ｅが泥５２の層の表面５２Ａに当接して、それ以上、筐体２を泥５２の層に埋め込むことができなくなった位置が、水田５０の水位がゼロの位置となる。 When the casing 2 is embedded in the mud 52 layer of the paddy field 50 and the lower surface 7E of the bottom plate part 7 of the umbrella part 6 abuts the surface 52A of the mud 52 layer of the paddy field 50, the bottom plate part 7 of the umbrella part 6 The resistance of the mud 52 layer is added. If it does so, it will become impossible to embed the housing | casing 2 in the layer of the mud 52 any more, and the embedding depth to the layer of the mud 52 of the housing | casing 2 will be prescribed | regulated. That is, the housing 2 is embedded in the mud 52 layer, the lower surface 7E of the bottom plate portion 7 of the umbrella portion 6 abuts the surface 52A of the mud 52 layer, and the housing 2 is embedded further in the mud 52 layer.

　（センサユニット）
　筐体２内には、センサユニット３が着脱自在に組込まれている。
　図５及び図６に示すように、センサユニット３は合成樹脂により形成された縦長のセンサ保持部材３０と、センサ保持部材３０に組付けられた縦長のプリント回路基板３１と、プリント回路基板３１上の上部側に搭載された水位センサ３２を覆うようにセンサ保持部材３０に取付けられたユニットカバー３３を有している。 (Sensor unit)

The unit cover 33 is attached to the sensor holding member 30 so as to cover the water level sensor 32 mounted on the upper side of the sensor.
　水位センサ３２は圧力センサからなり、測定地点の水圧を測定する。そして、測定された水圧と大気圧を比較することによって、水田５０の水位が測定される。 The water level sensor 32 is a pressure sensor and measures the water pressure at the measurement point. And the water level of the paddy field 50 is measured by comparing the measured water pressure and atmospheric pressure.
　なお、本実施形態においては、水位センサ３２がプリント回路基板３１上に１個搭載されたものであるが、本発明は水位センサをプリント回路基板３１上に２個搭載し、いずれか一方の水位センサを他方の水位センサが故障したときの代替用の水位センサとして使用するようにした構成のものであってもよく、プリント回路基板３１上に搭載される水位センサの個数には限定されない。 In this embodiment, one water level sensor 32 is mounted on the printed circuit board 31. However, in the present invention, two water level sensors are mounted on the printed circuit board 31, and one of the water level sensors is mounted.

　プリント回路基板３１上に２個の温度センサ、すなわち第１温度センサ３４及び第２温度センサ３５が搭載されているので、温度センサのいずれ一方が故障したとき、他方の温度センサを使用することによって、継続して泥５２の温度の測定を行うことができる。したがって、温度センサが故障する毎に水位温度測定装置を新しいものに取替える必要がなく、水位温度測定装置１の取扱いが簡単となる。 Since two temperature sensors, that is, the first temperature sensor 34 and the second temperature sensor 35 are mounted on the printed circuit board 31, when one of the temperature sensors fails, the other temperature sensor is used. The temperature of the mud 52 can be continuously measured. Therefore, it is not necessary to replace the water level temperature measuring device with a new one every time the temperature sensor breaks down, and the handling of the water level temperature measuring device 1 is simplified.
　また、第１温度センサ３４と第２温度センサ３５が深さ方向に所定距離を置いて搭載されているので、泥５２の深さ方向の２箇所の地点の温度を測定することができる。したがって、水田５０の所定地点における泥５２の温度を正確に測定することができる。 Also, since the first temperature sensor 34 and the second temperature sensor 35 are mounted at a predetermined distance in the depth direction, the temperature at two points in the depth direction of the mud 52 can be measured. Therefore, the temperature of the mud 52 at the predetermined point of the paddy field 50 can be accurately measured.

Water inlets 33 </ b> C are formed in the longitudinal direction of the unit cover 33 at a predetermined interval.
　センサユニット３は、水位センサ３２及び各温度センサ３４、３５が搭載されているプリント回路基板３１側が筐体２に形成された測定用開口部２Ｃに臨むように、且つ水位センサ３２が傘部６の底板部７の下端の位置（水位ゼロの位置）に保持されるように筐体２内に組込まれている。
　また、センサユニット３は、筐体２の内壁に突出形成された支持用リブ２Ｅによって、筐体２の内壁とセンサユニット３との間に隙間２Ｆが形成されるように筐体２内で支持されている。 The sensor unit 3 includes the water level sensor 32 and the temperature sensor 34, 35 so that the printed circuit board 31 side faces the measurement opening 2 </ b> C formed in the housing 2, and the water level sensor 32 includes the umbrella portion 6. The bottom plate portion 7 is incorporated in the housing 2 so as to be held at the lower end position (position where the water level is zero).
Further, the sensor unit 3 is supported in the housing 2 so that a gap 2F is formed between the inner wall of the housing 2 and the sensor unit 3 by the supporting ribs 2E that are formed to protrude from the inner wall of the housing 2. Has been.
　筐体２には、測定用開口部２Ｃに臨むようにフック部２Ｇが一体形成されている。ユニットカバー３３の正面部の下部にはフック部２Ｇが引っ掛けられる係止用凹部３３Ｄが形成されている。フック部２Ｇが係止用凹部３３Ｄに引っ掛けられることによって、センサユニット３は筐体２内に位置決め固定されている。 The housing 2 is integrally formed with a hook portion 2G so as to face the measurement opening 2C. At the lower part of the front portion of the unit cover 33, a locking recess 33D is formed on which the hook 2G is hooked. The sensor unit 3 is positioned and fixed in the housing 2 by hooking the hook portion 2G to the locking recess 33D.
　本実施形態の水位温度測定装置１では、センサユニット３は筐体２内に着脱自在に組込まれたものであるが、本発明はセンサユニットが筐体２内から取外すことができないように、組込まれているものであってもよい。 In the water temperature measuring apparatus 1 of the present embodiment, the sensor unit 3 is removably incorporated in the housing 2, but the present invention is incorporated so that the sensor unit cannot be removed from the housing 2.

　（水位温度測定装置の作用）
　水位温度測定装置１を水田５０に設置する場合、筐体２を下端２ａ側から水田５０の水中に挿入する。そして、筐体２を泥５２の層に差込み、そして埋め込んでいく。
　筐体２の下端２ａ側を水中に挿入していくと、水田５０の水面５１Ａが傘部６の底板部７の下面７Ｅに当接する。水田５０の水面５１Ａが傘部６の底板部７の下面７Ｅに当接すると、筐体２の挿入に対して抵抗力が発生するが、その抵抗力に抗して筐体２をさらに水中に挿入していく。 (Operation of water level temperature measuring device)
When the water level temperature measuring device 1 is installed in the paddy field 50, the casing 2 is inserted into the water of the paddy field 50 from the lower end 2a side. Then, the housing 2 is inserted into the mud 52 layer and embedded.
When the lower end 2 a side of the housing 2 is inserted into the water, the water surface 51 </ b> A of the paddy field 50 contacts the lower surface 7 </ b> E of the bottom plate portion 7 of the umbrella portion 6. When the water surface 51A of the paddy field 50 comes into contact with the lower surface 7E of the bottom plate portion 7 of the umbrella portion 6, resistance is generated against insertion of the housing 2, but the housing 2 is further submerged against the resistance. Insert it.
　そうすると、水５１は、第１底板側水連通口７Ｃ及び第２底板側水連通口７Ｄから傘部６の底板部７の上側に流れ込む。
　水５１は、第１底板側水連通口７Ｃ及び第２底板側水連通口７Ｄから傘部６の底板部７の上側に流れ込むと同時に、側板側水連通口８Ａからも傘部６の底板部７の上側に流れ込む。 Then, the water 51 flows into the upper side of the bottom plate portion 7 of the umbrella portion 6 from the first bottom plate side water communication port 7C and the second bottom plate side water communication port 7D.
The water 51 flows from the first bottom plate side water communication port 7C and the second bottom plate side water communication port 7D to the upper side of the bottom plate portion 7 of the umbrella portion 6, and at the same time, from the side plate side water communication port 8A, the bottom plate portion of the umbrella portion 6. 7 flows into the upper side.
　そして、筐体２を更に水中に挿入していくと、傘部６の底板部７の上側の水５１は、図７中矢印Ａ１方向及び矢印Ａ２方向に示すように、第１水流入口２Ａ及び第２水流入口２Ｂから筐体２の内壁とセンサユニット３との間に形成された隙間２Ｆを介して筐体２内の上部領域４に流れ込む。
　筐体２の上部流域４に流入した水５１は、図７中矢印Ｂ１及び矢印Ｂ２方向に示すように、センサユニット３のユニットカバー３３左右両側面部に形成されている第１カバー側水流入口３３Ａ及び第２カバー側水流入口３３Ｂからユニットカバー３３内に流れ込む。そして、水５１は、プリント回路基板３１の上部側に搭載されている水位センサ３２の位置まで流れ込む。なお、水５１は第３カバー側水流入口３３Ｃからもユニットカバー３３内に流れ込む構造である。図７においては、第３カバー側水流入口３３Ｃの図示は省略している。 Then, when the casing 2 is further inserted into the water, the water 51 on the upper side of the bottom plate portion 7 of the umbrella portion 6 has the first water inlet 2A and the second water inlet 2A as shown in the arrow A1 direction and the arrow A2 direction in FIG. It flows into the upper region 4 in the housing 2 through the gap 2F formed between the inner wall of the housing 2 and the sensor unit 3 from the second water inlet 2B.
As shown in the directions of arrows B1 and B2 in FIG. 7, the water 51 that has flowed into the upper basin 4 of the housing 2 is a first cover-side water inlet 33A formed on the left and right side portions of the unit cover 33 of the sensor unit 3. And it flows in into the unit cover 33 from the 2nd cover side water inflow port 33B. Then, the water 51 flows to the position of the water level sensor 32 mounted on the upper side of the printed circuit board 31. The water 51 is structured to flow into the unit cover 33 also from the third cover side water inlet 33C. In FIG. 7, the third cover side water inlet 33C is not shown.
　そして、筐体２の下端２ａを泥５２の層に差込み、そして埋め込んでいくと、泥５２は筐体２の泥流入口２Ｄから筐体２内の下部領域５に流れ込む。
　このように、筐体２に第１水流入口２Ａ及び第２水流入口２Ｂを設けることによって、筐体２内に組込まれている水位センサ３２の搭載位置に水５１をスムーズに流し込むことができる。また、泥流入口２Ｄを設けることによって、筐体２内に組込まれている各温度センサ３４、３５の搭載位置に泥５２をスムーズに流し込むことができる。したがって、水田５０の水位及び泥５２の温度を簡単かつ精度よく測定することができる。 Then, when the lower end 2 a of the housing 2 is inserted into the mud 52 layer and embedded, the mud 52 flows from the mud inlet 2 </ b> D of the housing 2 into the lower region 5 in the housing 2.
In this manner, by providing the first water inlet 2A and the second water inlet 2B in the housing 2, the water 51 can be smoothly poured into the mounting position of the water level sensor 32 incorporated in the housing 2. Moreover, by providing the mud inlet 2D, the mud 52 can be smoothly poured into the mounting positions of the temperature sensors 34 and 35 incorporated in the housing 2. Therefore, the water level of the paddy field 50 and the temperature of the mud 52 can be measured easily and accurately.

　また、筐体２が筒状に形成されているので、筐体２を泥５２の層に埋め込むとき、筐体２を抵抗なくスムーズに差し込み、そして埋め込んでいくことができる。したがって、筐体２内に組込まれている水位センサ３２、第１温度センサ３４及び第２温度センサ３５の損傷を防ぐことができる。 According to the present embodiment, since the water level and the temperature of the mud 52 layer at a predetermined point of the paddy field 50 can be measured simultaneously by the single water level temperature measuring device 1, the measurement data of the water level of the paddy field 50 and the temperature of the mud 52 are measured. Can be easily obtained, and the number of measuring devices to be used can be reduced.
Moreover, since the housing | casing 2 is formed in the cylinder shape, when the housing | casing 2 is embedded in the layer of mud 52, the housing | casing 2 can be smoothly inserted and embedded without resistance. Therefore, damage to the water level sensor 32, the first temperature sensor 34, and the second temperature sensor 35 incorporated in the housing 2 can be prevented.
