The rectifying circuit comprises a rectifying bridge stack A1 and a capacitor C1 which are connected through circuit board wiring, and the 3 and 4 pins of the power output end of the rectifying bridge stack A1 are respectively connected with the positive pole and the negative pole of the capacitor C1.
As shown in fig. 1 and 2, two ends of a power supply of a water flow generator M and 1 and 2 pins of a rectifier bridge stack a1 at two ends of a power supply input of a rectifier circuit are respectively connected through leads, 3 and 4 pins of the rectifier bridge stack a1 at two ends of the power supply output of the rectifier circuit and two poles of a storage battery G, the anode of a power supply input end diode VD of a detection circuit and the other end of a resistor R1, 1 and 2 pins of a GPRS module A3 of a data transmission circuit, and 1 and 2 pins of a power supply input end of a multi-parameter water quality detector body a2 are respectively connected through leads.

As shown in fig. 1 and 2, the water flow generator M of the present invention is usually located below the water surface, the flowing water flow drives the blades thereof to rotate, and then the water flow generator M (actual output voltage is about 14V) generates an ac power to enter the rectifier bridge stack a1, the rectifier bridge stack a1 rectifies the ac power and outputs the rectified ac power to the storage battery G after being filtered by the capacitor C1, and the storage battery G stores electric energy (diode VD is in one-way conduction effect) to supply power to related circuits (the water flow generator is used in combination with the storage battery to supply power, so that the influence of weather environment on power supply is overcome, and the supply of electric energy is ensured on the premise of saving cost). After the detection circuit is powered on to work, if the water flow of a river is smooth, the electric energy generated by the generator M is relatively small, a power supply output by a pin 3 of the rectifier bridge stack A1 is subjected to voltage division through the adjustable resistor RP1 and the resistor R1, the voltage is reduced and the current is limited through the resistor R2, the base of the NPN triode Q1 is lower than 0.7V, the NPN triode Q1 cut-off relay K is in a power-off state (the input end of the power supply and the normally closed contact end are controlled to be closed), and therefore the time control switches A4 and A5 are in a power-on working state. After the time control switches A4 and A5 are powered on to work, power can be output at intervals to enter positive and negative and positive two-pole power input ends of a motor reducing mechanism M1 (for example, the time control switches A4 and A5 alternately output 1-minute power every 10 minutes), so that in the time when the positive and negative two poles of the motor reducing mechanism M1 are powered on, the motor reducing mechanism can alternately drive a connecting rod 104 to rotate clockwise and anticlockwise, a probe head 6 of a corresponding multi-parameter water quality detector body can alternately rotate clockwise and anticlockwise, and water quality of relatively more areas and points in a river is detected. In practical situations, the motor reduction mechanism M1 drives the connecting rod 104 to rotate clockwise and counterclockwise before dead points, the front and rear ends of the linkage plate 106 can respectively contact the buttons of the two power switches S1 and S2, and the internal contacts of the power switches S1 and S2 are respectively opened, because the two terminals of the power switches S1 and S2 are respectively connected in series with the 3 pins of the time control switches a4 and a5 at the two power output ends of the time control circuit and the positive and negative power input ends of the motor reduction mechanism M1, when the power output shaft of the motor reduction mechanism M1 drives the probe to rotate clockwise to the left dead point, the positive power input end of the motor reduction mechanism M1 loses power and does not work any more, and only the reverse input power can obtain electric work; when the power output shaft of the motor speed reducing mechanism M1 anticlockwise drives the detecting head to rotate to a right dead point, the input end of the negative power supply of the motor speed reducing mechanism M1 loses power and does not work any more, and only the power supply input in the reverse direction can work; through the above, the influence on the whole work caused by the uncontrolled rotation of the motor speed reducing mechanism is prevented.
As shown in fig. 1 and 2, after the detection circuit is powered on and works, if the water flow of a river is relatively rapid, the electric energy generated by the generator M is relatively large, the power output by the rectifier bridge stack a1 is divided by the adjustable resistor RP1 and the resistor R1, the voltage is reduced and the current is limited by the resistor R2, the voltage is reduced and the current is limited, the base of the NPN triode Q1 is higher than 0.7V, the NPN triode Q1 is connected with the collector to output low level and enters the negative power input end of the relay K, the relay K is in a powered state and controls the power input end and the normally closed contact end to be open, and the power input end and the normally open contact end to be closed, so that the time control switches a4 and a5 are in a powered-off state, the relay K1 is powered on and controls the power input end and the normally closed contact end, and further, the positive and negative poles and the negative poles of the motor speed reduction mechanism M1 are powered, and the motor speed reduction mechanism drives the connecting rod 104 to rotate to stop. Through the above, the connecting rod 104 is in the longitudinal state and the water flow is in the longitudinal straight line when the river water flow is large at ordinary times, so that the influence of the excessive water flow on the connecting rod 104 on the service life of the connecting rod is prevented (that is, when the water flow is urgent, the connecting rod 104 cannot move and the water flow impact direction is vertical to prevent the damage and the like caused by the excessive water flow impact). The multi-parameter water quality detector body A2 can detect the quality of water of river in real time under the effect of supporting detecting head 6 after work, the data of detection exports GPRS module A3's signal input end through the RS485 port, GPRS module A3 passes water quality data through wireless mobile network teletransmission, and like this, under the condition that the relevant personnel of far-end are not at the scene, the concrete quality of water condition that can real-time very first time understand, the relevant personnel of far-end can obtain more river course quality of water data in real time, have played powerful data support for more effective management river course. In fig. 2, resistances R1 and R2 are 100K and 10K, respectively; the model of the NPN triode Q1 is 9013; the capacitor C1 is model 470 UF/25V; relay K, K1 model DC 12V; the diode VD model is 1N 4007; the GPRS module A3 is ZLAN8100 in model, and an RS485 data input port (two power input ends and one signal input end) is arranged on a GPRS module finished product; the time control switches A4 and A5 are full-automatic microcomputer time control switch finished products of model KG316T, the microcomputer time control switch has a plurality of keys of cancel/recovery, time correction, week correction, automatic/manual, timing and clock, and has two power input ends 1, 2 feet and two power output ends 3, 4 feet, a user respectively presses and operates the plurality of keys, and the interval time of the two power output ends for outputting power and the time of each power output can be set; the model of the adjustable resistor RP1 is 2M (the model is adjusted to 1.12M); rectifier bridge stack a1 is model GBU 810.
