The embodiment of the application is written in a progressive manner.

As shown in fig. 1 to 5, the real-time pollution-free intelligent water quality detection device provided by the embodiment of the utility model is of a hull structure, the center of gravity of the hull moves forward, and the whole posture is downward, and comprises: the device comprises a shell, an optical sensing module 1, a sampler 2, a reagent bottle 3 and an electric propulsion module 4, wherein the sampler 2 is positioned at the middle front end in a cabin and is used for extracting a water body sample of a detection area through a sampling port on the side surface of a ship body; the reagent bottle 3 is vertically arranged behind the sampler 2 and is used for storing a water body sample; the optical sensing module 1 is positioned in the notch below the bow and is used for detecting and analyzing the water body sample to obtain a detection result; the electric propulsion module 4 is arranged in the floating bodies at the two sides of the ship body and is used for providing propulsion power in water.

The embodiment of the utility model comprises a shell, an optical sensing module 1, a sampler 2, a reagent bottle 3 and an electric propulsion module 4, wherein the whole ship body is designed to ensure the reliability service of water quality detection, not only ensures the accuracy of water quality detection, but also ensures that the optical sensing module 1 is required to be always kept under the water surface, so that the whole ship body is downward in posture, the optical sensing module 1 is positioned in a notch below the ship head, main parts of a patrol ship are concentrated on the side of the ship head to move forward the center of gravity of the ship, and floating bodies at two ends of the electric propulsion module 4 are slightly higher than the ship body, so that the ship head is kept downward in posture. When the ship detects that the water quality exceeds the standard, the sampler 2 is automatically started to collect the water body sample and pump the water body sample into the reagent bottle 3 for storage. The sampler 2 extracts a water body sample of the detection area through a sampling port on the side surface of the ship body, the water body sample is stored in a reagent bottle 3 in the cabin, and the reagent bottle 3 can be taken from an opening at the upper end of the ship body.

In the real-time pollution-free intelligent water quality detection device shown in the above figures, the optical sensing module 1 comprises a light source 101, a light absorption tank 102, an optical sensor 103, a power supply module 104, a communication module 105 and a control module 106; a light source for emitting a stable continuous spectrum; the light absorption pool is used for accommodating a water body sample; the optical sensor is used for detecting the light intensity transmitted through the light absorption cell to obtain an initial electric signal; the power module is used for providing electric energy; the control module is used for calculating and processing the initial electric signals to obtain measured electric signals and absorbance data of the water body sample; the communication module is used for uploading the measured electric signals and absorbance data to the microcomputer processing end; the light source and the optical sensor are respectively positioned at two sides of the light absorption tank and are arranged on a horizontal line; an optical lens 107 is also arranged among the light source, the light absorption tank and the optical sensor, and the optical lens 107 is perpendicular to the horizontal plane.

In the embodiment of the utility model, after a real-time pollution-free intelligent water quality detection device is put into a water sample, an optical lens 107 is kept in a state vertical to a horizontal plane, a light source 101, a light absorption tank 102 and an optical sensor 103 are connected into a line parallel to the horizontal plane, sediment adhesion can be avoided, a test result is shown in fig. 6, a purple solid line shows absorbance data at 265nm, a red dotted line shows reference absorbance data when no sediment interference is generated by an instrument, ultraviolet band absorbance data can be obviously seen to rapidly rise under the interference of sediment deposition in a rapid (1S/time) continuous measurement mode of the instrument, the suspension posture of the instrument in water is changed, the instrument is kept in a horizontal posture in lake water, so that sediment is not easy to generate, the absorbance data can be rapidly recovered to be normal, and the corresponding absorbance data is continuously increased again according to the original rule after the suspension posture is changed to be the vertical horizontal plane. In contrast, if the sensor module does not adopt the floating posture of the present utility model, especially if the optical lens 107 is kept horizontal to the horizontal plane, and the light source 101, the light-absorbing cell 102, and the optical sensor 103 are connected in a line perpendicular to the horizontal plane, the deposition phenomenon will greatly interfere with the accuracy of the measurement module in a short time. As shown in FIG. 7, it was found that the contaminants formed a deposit on the window surface within about 30min, and that the COD detection value was continuously increased from 20mg/L to 50mg/L without algorithm compensation, and that the nitrate, total P, and total N parameter detection indication values were significantly larger than the true values, thereby seriously affecting the equipment accuracy. This means that the disturbance caused by the deposition phenomenon can be effectively eliminated by changing the suspension posture of the instrument.

In general, the light source 101 is opposite to the optical lens 107 so that more light can pass through the light absorption cell 102, the light sensitive surface of the optical sensor 103 is opposite to the optical lens 107 so as to realize sensing, the light source 101 and the optical sensor 103 are distributed on the left and right sides of the light absorption cell 102 without specific requirements, the measured electric signal and absorbance data of the water body sample are obtained through measurement, and are uploaded to the microcomputer processing end through the communication module 105, so that the accurate real-time measurement of the water body sample is realized, the error caused by the deposition phenomenon can be effectively solved, and the maintenance-free, real-time and pollution-free optical water quality detection is realized. Specifically, the communication module 106 is a 4G/NB-lot communication module.

Further, in the real-time pollution-free intelligent water quality detection device provided by the embodiment of the utility model, the optical lens 107 is a planar optical lens. The optical lens 107 may be a condenser lens or a planar optical lens, and has a similar advantageous effect, although no parallel light is formed.

In the utility model, after the LED optical signals with different wave bands are effectively converted by the photodiode, an electric signal for reacting absorbance can be generated, absorbance data with different wave bands can react with different pollutants, such as the concentration of absorbance-reactive nitrate substances at 220 nm; absorbance data sets of four wave bands of 254nm, 265nm, 275nm and 310nm can be fitted through PLS algorithm, and COD concentration of a water body can be obtained through joint inversion, wherein in the traditional design, either 254nm single wave band or 254nm plus single visible wave band is used for compensating turbidity interference, or full spectrum inversion is used for COD. However, the pollution information of the single ultraviolet light source reaction is not comprehensive, the full spectrum cannot effectively reduce the cost and the volume, so that the utility model selects a plurality of wave band ultraviolet LED light sources so as to reflect more comprehensive water quality information; in the infrared part, experiments show that the absorbance data size at 1650nm is positively correlated with the total P content of the water body, and the absorbance data size at 2100nm is positively correlated with the total N content of the water body, so that the absorbance data at the two positions are used for reflecting the total P content and the total N content of the water body, and the infrared light absorption effect of the water body is strong, so that the optical path in the mechanical design is as small as possible to ensure that light sufficiently penetrates through a water sample to be detected. Through the multi-band absorbance data of ultraviolet-visible-infrared, the utility model can effectively detect and early warn a plurality of parameters of nitrate, COD, total P and total N.
