Description
本発明は、液体が流れる箇所に設置され液体の水質を測定する無線式水質分析計に関し、自身で使用する電力を自家発電により賄うようにした無線式水質分析計に関する。 TECHNICAL FIELD The present invention relates to a wireless water quality analyzer that is installed at a location where a liquid flows and measures the quality of the liquid water, and relates to a wireless water quality analyzer configured to supply electric power used by itself by private power generation.
図２は無線式水質分析計の一般的な構成を示すもので、１は水質を検出する水質計、２は被測定水が流れる槽（以下、流水槽）、３は水質計１を適正な水深を保つように固定する浸漬式ホルダー、４はスタンション、５は浸漬式ホルダー３を流水槽の端に立てられたスタンション４に固定する止め金具、６は変換器（伝送器）、７は変換器６の内部にあるワイヤレス送信装置、８は変換器６の内部にある電源装置、９は建屋、１０は流水槽２の陸上にあるスタンション４あるいは建屋９等に据え付けられる変換器、１１は変換器１０の内部にあるワイヤレス受信装置である。 FIG. 2 shows a general configuration of a wireless water quality analyzer. 1 is a water quality meter for detecting water quality, 2 is a tank (hereinafter referred to as a flowing water tank) through which water to be measured flows, and 3 is an appropriate water quality meter 1. Immersion type holder for fixing the water depth, 4 is a stanchion, 5 is a stopper for fixing the immersion type holder 3 to the stanchion 4 standing at the end of the flowing water tank, 6 is a converter (transmitter), 7 is a conversion Wireless transmission device inside the vessel 6, 8 a power supply device inside the transducer 6, 9 a building, 10 a converter installed on the stanchion 4 or building 9 on the land of the flowing water tank 2, 11 a conversion This is a wireless receiver inside the device 10.
上述の構成において、水質計１は、流水槽２内の水質データ（ＤＯ、ＭＬＳＳ、ｐＨ、ＯＲＰ等の計測値）を検出して、各種センサーがそれぞれ特殊な電気信号を発生する。その電気信号は、変換器６のワイヤレス送信装置７でワイヤレス信号に変換され無線送信される。水質計１とワイヤレス送信装置７は、電源装置８から電源が供給され、水質計１は外部からの電源供給なしに現場で独立稼働する。 In the above-described configuration, the water quality meter 1 detects water quality data (measured values such as DO, MLSS, pH, ORP, etc.) in the flowing water tank 2, and each sensor generates a special electrical signal. The electrical signal is converted into a wireless signal by the wireless transmission device 7 of the converter 6 and transmitted by radio. The water quality meter 1 and the wireless transmission device 7 are supplied with power from the power supply device 8, and the water quality meter 1 operates independently at the site without external power supply.
ワイヤレス送信装置７から無線送信されるワイヤレス信号は、気中を伝搬し、流水槽２の陸上に設置される変換器１０の内部にあるワイヤレス受信装置１１で無線受信され、再度電気信号に変換され、変換器１０で共通信号（４〜２０ｍＡ等）に変換されて図示しない監視室等へ伝送される。 The wireless signal wirelessly transmitted from the wireless transmission device 7 propagates in the air, is wirelessly received by the wireless reception device 11 inside the converter 10 installed on the land of the flowing water tank 2, and is converted into an electrical signal again. The converter 10 converts the signal into a common signal (4 to 20 mA or the like) and transmits it to a monitoring room (not shown).
図３は図２で示す無線式水質分析計の配線関係の詳細を示すもので、矢印Ｓは信号伝送線を示し、矢印Ｐは電力供給線を示している。
図２に示すように、従来のセンサは無線式とはいえ、電力は変換器（伝送器）６から供給される電力を用いて水質計１内のセンサ部を駆動させていた。
低電力の２線式伝送器では電力が限られており、その限られた電力でセンサからの出力信号等の増幅を賄ってきた。
FIG. 3 shows the details of the wiring relationship of the wireless water quality analyzer shown in FIG. 2, wherein an arrow S indicates a signal transmission line and an arrow P indicates a power supply line.
As shown in FIG. 2, although the conventional sensor is a wireless type, the power is driven by the sensor unit in the water quality meter 1 using the power supplied from the converter (transmitter) 6.
Low-power two-wire transmitters have limited power, and the limited power has been used to amplify output signals from sensors.
従って本発明は、水質計自身が独立して電力を発電することで、変換器（伝送器）からの電力供給を不要とするものであり、かつ独立した無線式水質分析計を提供することを目的としている。 Therefore, the present invention provides an independent wireless water quality analyzer that eliminates the need for power supply from a converter (transmitter) by the water quality meter itself generating power independently. It is aimed.

以上説明したことから明らかなように本発明によれば、
回転翼付き円筒の内周にコアとコイルが配置され中心に配線が可能な空洞が形成された発電機と、
この発電機の一端に上部スリップリングを介して配置され蓄電手段およびワイヤレス送信装置を備えた変換器と、
前記発電機の他端に下部スリップリングを介して配置された水質計と、
からなり、
前記発電機を測定成分を含む流水槽に浸漬して水流により前記回転翼を回転させて発電し、発電した電力を前記発電手段に蓄電し、蓄電された電力を前記空洞に配置された配線を介して前記水質計および前記変換器に供給するとともに、前記水質計で検出された測定信号を前記ワイヤレス送信装置に伝送して発信するので、変換器（伝送器）からの電力供給が不要となり、かつ独立した無線式水質分析計を提供することができる。
As is clear from the above description, according to the present invention,
A generator in which a core and a coil are arranged on the inner periphery of a cylinder with a rotor blade and a cavity capable of wiring in the center is formed;
A converter provided with an electricity storage means and a wireless transmission device disposed at one end of the generator via an upper slip ring;
A water quality meter disposed at the other end of the generator via a lower slip ring;
Consists of
The generator is immersed in a flowing water tank containing a measurement component, and the rotor blades are rotated by a water flow to generate power, the generated power is stored in the power generation means, and the stored power is disposed in the cavity. Since the measurement signal detected by the water quality meter is transmitted to the wireless transmission device and transmitted to the water quality meter and the converter through the power supply from the converter (transmitter) becomes unnecessary, and it is possible to provide a separate wireless quality analyzer.
図１は無線式水質分析計の一部断面構成図（ａ）及び（ａ）図のＡ−Ａ断面図（ｂ）である。
これらの図において、１は水質計、２０は変換器（伝送器）であり、この変換器２０内には、ワイヤレス送信装置２１、ＣＰＵ２１、プリアンプ２３などが収納されている。
FIG. 1 is a partial cross-sectional configuration diagram (a) of the wireless water quality analyzer and a cross-sectional view A-A in FIG.
In these drawings, 1 is a water quality meter, and 20 is a converter (transmitter). In this converter 20, a wireless transmission device 21, a CPU 21, a preamplifier 23, and the like are accommodated.
２７は外周に複数（図では８枚）の回転翼２５が形成された回転翼付き円筒であり、この回転翼付き円筒内にはコア（鉄心相当）２８及びコイル２９が配置され、中心部の空洞３３には水質計１と変換器２０を接続する信号伝送線３０が配置されている。
Reference numeral 27 denotes a cylinder with a rotor blade in which a plurality (eight in the figure) of
３１は変換器２０と回転翼付き円筒２７の間に配置された上部スリップリング、３２は回転翼付き円筒２７と水質計１との間に配置された下スリップリングであり、回転翼付き円筒２７はコイル２９の外周を水密な状態を維持して回転可能な構成となっている。 Reference numeral 31 denotes an upper slip ring disposed between the transducer 20 and the cylinder 27 with the rotor blades, and 32 denotes a lower slip ring disposed between the cylinder 27 with the rotor blades and the water quality meter 1. Is configured such that the outer periphery of the coil 29 can be rotated while maintaining a watertight state.
上述の構成において、回転翼付き円筒２７を流水槽２内に浸漬すると水流により回転翼２５を介して回転翼付き円筒２７が回転する。この回転により円筒内に設けられたコイル２９が電極類の外側に設けられたコア部品２８の外側を回転しコイル内に電流を誘導する。誘導された電流はブラシ式端子によりプリアンプ部へ電力として伝送される。
In the above-described configuration, when the rotating blade-equipped cylinder 27 is immersed in the flowing water tank 2, the rotating blade-cylinder 27 is rotated via the rotating
プリアンプでは電力を図示しないコンデンサ類に蓄電する。このコンデンサ類に充電された電力を用いてＣＰＵ２２、水質計１を構成する電子部品に電力が供給され、水質計で計測された測定信号がワイヤレス送信装置を介して発信される。
In the preamplifier, electric power is stored in capacitors (not shown). Electric power is supplied to the electronic components constituting the
上述のように無線式水質分析計が自家発電する事により、単独で自律的に測定、演算、信号伝送を行うことが出来、センサ自身への電力供給が不要になる。
即ち、低電力で測定、演算、信号伝送を行い変換器（伝送器）の電力使用を抑えることが出来る。
また、電極外側に設けられたコアによってシールド効果を高められることで、外部からのノイズに対しても耐性をもたせることができる。
As described above, when the wireless water quality analyzer generates power in-house, it can independently perform measurement, calculation, and signal transmission independently, and power supply to the sensor itself becomes unnecessary.
That is, measurement, calculation, and signal transmission can be performed with low power to suppress the power consumption of the converter (transmitter).
In addition, since the shielding effect is enhanced by the core provided outside the electrode, resistance against external noise can be provided.
なお、以上の説明は、本発明の説明および例示を目的として特定の好適な実施例を示したに過ぎない。例えば回転翼の形状は図では長方形状の板として８枚を示したが、回転翼の枚数はこれに限ることなく多くても少なくても良い。また、回転翼の形状も曲線でもよく斜め方向に取付けてもよい。従って本発明は、上記実施例に限定されることなく、その本質から逸脱しない範囲で更に多くの変更、変形を含むものである。 The above description merely shows a specific preferred embodiment for the purpose of explanation and illustration of the present invention. For example, in the drawing, the shape of the rotor blades is eight as a rectangular plate in the figure, but the number of rotor blades is not limited to this and may be more or less. Further, the shape of the rotary blade may be curved or attached in an oblique direction. Therefore, the present invention is not limited to the above-described embodiments, and includes many changes and modifications without departing from the essence thereof.
