[0065] Exemplary embodiments of the present application are described herein with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating preferred embodiments of the application, are given by way of illustration only, and are not by way of limitation.

[0066] The embodiments of the present application provide a water environment monitoring device, wherein, Figures 1 to 6 Embodiment One is shown, Figures 7 to 12 Embodiment Two is shown.

[0067] Referring to Figure 1 In Embodiment One of the present application, the water environment monitoring device can include a first light source 110 for providing incident light.

[0068] The water environment monitoring device can include a window seat 200 defining a detection area 300 and an exit portion 210, a first detection portion 220 and a second detection portion 230 arranged around the detection area 300. The detection area 300 is open so that the water to be measured can flow through or fill the detection area 300. The scattered light and / or fluorescence formed by the incident light in the water to be measured can enter the first detection portion 220, and the transmitted light of the incident light that has passed through the water to be measured can enter the second detection portion 230. The distance between the exit portion 210 and the second detection portion 230 is greater than or equal to 2 mm and less than or equal to 50 mm to meet the test optical path requirement. Compared with separate transmission detection or scattering detection, the water environment monitoring device provided by the embodiments of the present application can simultaneously realize detection of, for example, scattering, fluorescence, and transmission types, to meet more detection index requirements. The exit portion 210 is used to be connected with the light source so that the light emitted by the light source can enter the detection area 300 through the exit portion 210. The water filling in the detection area indicates that the water to be measured can not be flowing, for example, the detection device is placed in a container filled with water for measurement, at this time the water is filled in the detection area.

[0069] The water environment monitoring device can be configured such that the incident light can enter the detection area 300 through the exit portion 210, the scattered light and / or fluorescence of the incident light at the detection area 300 can enter the first detection portion 220, and the transmitted light of the incident light that transmits through the detection area 300 can enter the second detection portion 230. The water environment monitoring device provided by the embodiments of the present application has a complete incident light path and necessary components, can realize in-situ detection underwater, realizes multi-parameter detection, and can obtain various spectral information such as transmission, scattering, fluorescence, etc. of the water body to be detected, and realizes detection of multiple indexes.

[0070] Further, the water environment monitoring device can include a second light source 120. The optical axis of the first light source 110 and the optical axis of the second light source 120 can have an included angle. For example, the optical axis of the first light source 110 and the optical axis of the second light source 120 can be perpendicular or formed at other angles. The water environment monitoring device can include an optical lens, and the light emitted by the first light source 110 and the second light source 120 can form incident light via the optical lens. It can be understood that the setting form of the dual light source can provide more wavelength selection compared with a single light source, realize more detection requirements, and at the same time can also make the lamp beads as close to the optical axis as possible. Of course, the water environment monitoring device can also include more light sources.

[0071] Further, the wavelengths of the light emitted by the first light source 110 and the second light source 120 can be set to be different, and the first light source 110 and the second light source 120 are configured to be able to control the switch respectively. Thus, more wavelength selection can be provided for the incident light by controlling the switch of the light source, and various detection requirements can be met.

[0072] Further, the first light source 110 and / or the second light source 120 can be formed as an LED (light-emitting diode) lamp panel, and the LED lamp panel is integrated with a single or multiple lamp beads. For example, the LED lamp panel can have a single lamp bead, 2, 3, 6, 9 lamp beads, etc. The colors of the light emitted by each lamp bead can be the same or different. The setting of the light source in the form of integrated LED can make the positions of each lamp bead (if more than 2) more concentrated.

[0073] Further, referring to Figure 3 , the first optical lens 410 can be a dichroic mirror, the light of the first light source 110 can transmit through the first optical lens 410, and the light of the second light source 120 can be reflected by the first optical lens 410, and then the light of the two light sources can be combined into incident light. For example, the optical axes of the first light source 110 and the second light source 120 are perpendicular, and the mirror surface of the first optical lens 410 is inclined at 45° to the optical axes of the first light source 110 and the second light source 120. Of course, the optical lens can also be other structures that can combine two beams of light into one beam of light.

[0074] Further, the water environment monitoring device can further comprise a second optical lens 420 and a third detection unit 500. The second optical lens can also be a dichroic mirror. The water environment monitoring device is configured such that the incident light can pass through the second optical lens 420 into the exit unit 210, and the incident light can also be reflected by the second optical lens 420 into the third detection unit 500 without passing through the water body to be measured. The third detection unit 500 can be provided with a sensor capable of detecting changes in incident light, such as changes in light intensity, wavelength and spectral line of incident light, which can be used for light intensity correction or reference.

[0075] Of course, the first optical lens and the second optical lens are not limited to being dichroic mirrors, but can also be other optical lenses as long as they can achieve partial light reflection and partial light transmission. For example, quartz. One side of the quartz can be coated to achieve reflection and transmission functions.

[0076] Further, the water environment monitoring device can further comprise a first lens 430, a second lens 440 and a third lens 450. The first lens 430 can be arranged between the first light source 110 and the first optical lens 410, the second lens 440 can be arranged between the second light source 120 and the first optical lens 410, and the third lens 450 can be arranged between the second optical lens 420 and the exit unit 210. Each lens can be an aspherical lens, which has stronger light converging ability.

[0077] Further, the water environment monitoring device can further comprise an optical path seat for bearing the optical lens, the first light source 110 and the second light source 120. The optical path seat can comprise a first optical path seat 630 and a second optical path seat 640. The first optical path seat 630 and the second optical path seat 640 can be provided with a clamping mechanism 650 such as a positioning protrusion, so that the aforementioned dichroic mirror, lens and other structures can be positioned and arranged on the optical path seat respectively. More specifically, the lens and the dichroic mirror can be bonded to the clamping mechanism 650 on the optical path seat, and the light source and the sensor can be threadedly connected to the optical path seat.

[0078] The optical path seat (more specifically, the second optical path seat 640) has an insertion part 610, and the window seat 200 has an insertion opening 620. The optical path seat and the window seat 200 are connected by the insertion part 610 and the insertion opening 620, and are connected in a sealed manner, which facilitates installation and meets the accuracy requirements.

[0079] Further, the outer side of the second optical path seat 640 can be provided with a light shield 660 to prevent the optical path from being affected by stray light, for example.

[0080] Further, referring to Figure 6 , the window seat 200 can be formed in a U-shaped structure, the exit unit 210 and the second detection unit 230 are located at the two arm portions of the U-shaped structure, and the first detection unit 220 is located at the bottom of the U-shaped structure.

[0082] Further, the first detection part 220 can further comprise a quantum dot filter film, and the quantum dot filter film can be arranged at the side of the quantum dot light splitting sheet away from the detector. The quantum dot filter film is used to filter the incident light irradiated to the quantum dot filter film, that is, the light emitted by the light source can not directly enter the area of the quantum dot filter film covered by the detector 700 of the first detection part, and the scattered light and / or fluorescence can enter. The area of the quantum dot filter film can be smaller than the area of the quantum dot light splitting sheet. Further, the window seat 200 can comprise an exit window sheet 211, a first window sheet 221, and a second window sheet 231. The light in the exit part 210 can enter the detection area 300 through the exit window sheet 211, and the light in the detection area 300 can enter the first detection part 220 and the second detection part 230 through the first window sheet 221 and the second window sheet 231.

[0083] Taking the first detection part 220 as an example, the first detection part 220 can comprise an opening 222, a cover plate 223, and a sealing ring 224.

Therefore, the first window sheet 221 and the cover plate 223 can seal the detector 700 in the first detection part 220.

[0084] Similarly, the second detection part 230 can be sealed through the second window sheet 231 and the corresponding cover plate and sealing ring.
