Description

Technical Field

[0001] This application relates to the technical field of water quality detection. Specifically, it relates to a monitoring device for eutrophic water bodies. Background Art

[0002] Water eutrophication refers to the fact that under the influence of human activities, nutrients such as nitrogen, phosphorus, and oils required by organisms enter slow-flowing water bodies such as lakes, rivers, and bays in large quantities. Due to water eutrophication, algae and other plankton reproduce rapidly, forming a layer of "green scum". As a result, harmful gases produced by the decomposition of organic substances accumulated at the bottom under anaerobic conditions and biotoxins produced by some plankton can also harm fish. The oil content exceeds the self-purification capacity of the water body, causing changes in the physical, chemical properties or biological community composition of the water quality and bottom sediment. The floating oil on the water surface will affect the replenishment of oxygen in the water and the photosynthesis of plants, and can also extract chlorinated hydrocarbons dispersed in the water body, such as pesticides like dieldrin and toxaphene, and polychlorinated biphenyls, etc., and concentrate these poisons on the water surface layer to poison aquatic organisms. It is necessary to regularly monitor water quality indicators to understand the current situation and changing trends of water quality.

[0003] However, floating algae and floating oil have the characteristics of gathering on a flat water surface and dispersing on a rolling water surface, and will transfer with the flow of water. Static water sampling requires a specific flat water area to sample floating algae and floating oil, and it is relatively easy to monitor water samples. In dynamic water bodies, floating algae and floating oil are dispersed and difficult to gather. It is very difficult for floating algae and floating oil water samples that do not reach a certain purification concentration to show color in the spectral band under reagents, and processes such as filtration and distillation are required for purification. The monitoring efficiency of floating algae and floating oil in dynamic water bodies is low, and the sampling cycle of floating algae and floating oil water samples is long. Summary of the Invention

The water collection trough frame 110 is controlled by the first sliding cylinder 330 and the second sliding cylinder 350 to lift and leave the water surface, and is driven by the conveying motor 560 to move the water collection trough frame 110 near the screening box frame 710. The water collection trough frame 110 at one place of the discharge gate leaf 150 is controlled by the opening motor 360 to incline downward towards the guide inclined plate 711. The discharge gate leaf 150 is controlled by the discharge motor 160 to rotate and open. The sealed water sample flows into the guide inclined plate 711 along the gap between the discharge gate leaf 150 and the discharge gate leaf 150. The floating algae in the water sample are screened and filtered through the screening filter 712, and are evaporated and dried by natural light. The detection personnel can periodically scrape off the floating algae to analyze the types and contents of the floating algae in the area. The floating oil and the water body flow into the sedimentation box frame 720 through the screening filter 712. If the water sample is colored or turbid and contains some other interfering substances, the flocculant is injected into the sedimentation box frame 720 through the liquid metering port 721, and the water sample is sedimented and stratified by standing still. The light-shielding plate 750 is controlled by the curtain cylinder 740 to fall, reducing the interference of light transmission in the screening box frame 710. The monitoring main body 760 measures the concentration of oil molecules in the water by the ultraviolet fluorescence method. The oil molecules are activated to the excited state under the irradiation of specific ultraviolet light. This excited state is very unstable and will quickly return to the ground state. During the process of returning to the ground state, radiation fluorescence will be generated. By controlling the emission wavelength of the ultraviolet light and selecting the specific fluorescence wavelength scattered back by the oil molecules, the types of floating oil and the concentration in the water are analyzed periodically. Sampling is carried out regularly through the liquid separation port 770, facilitating the analysis and detection of other components of the water sample. The sampling and monitoring of floating algae and floating oil in dynamic and static water bodies are realized, with high automation degree, convenient pretreatment and classification of water samples, periodic sampling and monitoring of eutrophic water bodies, and convenient analysis and research on the current situation and change trend of water quality.

[0051] Specifically, the working principle of the monitoring device for eutrophic water bodies is as follows: When the water body monitoring area is in a static and gentle water area, the water collection tank frame 110 is moved above the sampling water area through the operating device. The first sliding cylinder 330 and the second sliding cylinder 350 are used to control the water collection tank frame 110 to sink half below the water surface. The power motor 370 is used to control the slow rotation of the water collection tank frame 110. Under the guiding action of the guiding blades 120, the water flow impacts the overflow gate blades 130. At this time, the water flow has a certain dynamic potential energy. The floating algae and floating oil climb up and flow into the water collection tank frame 110 between the overflow gate blades 130 and the discharge gate blades 150 driven by the water flow. When the water sample height between the overflow gate blades 130 and the discharge gate blades 150 is higher than the water surface height of the water area, the discharge gate blades 150 are controlled to rotate and open by the discharge motor 160. A drainage gap is left between the lower end of the discharge gate blades 150 and the bottom of the water collection tank frame 110. The floating algae and floating oil are restricted in the upper layer of the water body between the flow gate blades 130 and the discharge gate blades 150.

[0052] When the water body monitoring area is in a dynamic water area, the opening of the water collection tank frame 110 is controlled to rotate downward by the opening motor 360. The rotation speed of the water collection tank frame 110 is increased by the power motor 370 to increase the water intake of the water collection tank frame 110. The floating algae and floating oil climb up and flow into the water collection tank frame 110 between the overflow gate blades 130 and the discharge gate blades 150 driven by the water flow. The overflow gate blades 130 are controlled to rotate and open by the overflow motor 140. A water passage gap is left between the lower end of the overflow gate blades 130 and the bottom of the water collection tank frame 110. The discharge gate blades 150 are controlled to rotate and open by the discharge motor 160. A drainage gap is left between the lower end of the discharge gate blades 150 and the bottom of the water collection tank frame 110. The lower ends of the overflow gate blades 130 and the discharge gate blades 150 form a lower layer water flow channel, while the floating algae and floating oil are restricted in the upper layer of the water body between the flow gate blades 130 and the discharge gate blades 150.

[0053] The compliance status of the purification concentration of floating algae and floating oil in the water collection tank frame 110 is monitored by imaging. The windshield 170 is used to reduce the shaking of the floating oil and floating algae water body between the overflow gate blades 130 and the discharge gate blades 150. The overflow gate blades 130 are controlled to rotate and close by the overflow motor 140. The discharge gate blades 150 are controlled to rotate and close by the discharge motor 160 to seal the water sample, which is then transported out by the transfer device. Compared with the cumbersome purification and sampling of traditional eutrophic water bodies, the device can adjust the sampling water intake according to the dynamic and static changes of the water body, utilize the buoyancy of floating algae and floating oil themselves, and filter the floating algae and floating oil in the water body through water layer diversion, so as to achieve the purpose of purification. The monitoring efficiency of water body floating algae and floating oil is high, and the sampling period of floating algae and floating oil water samples is short.

[0054] Further, the counterweight pier 510 is installed on the water area shore through a concrete foundation, the support pier 520 is added according to the height difference between the shore height and the water surface height of the water area. After the water collection trough frame 110 finishes sampling, the flow-through gate leaf 130 rotates and closes, and the discharge gate leaf 150 rotates and closes to seal the water sample. The water collection trough frame 110 is controlled by the first sliding cylinder 330 and the second sliding cylinder 350 to lift away from the water surface, and is driven by the conveying motor 560 to move the water collection trough frame 110 near the screening box frame 710. The water collection trough frame 110 at one place of the discharge gate leaf 150 is controlled by the opening motor 360 to incline downward towards the diversion inclined plate 711. The discharge gate leaf 150 is controlled by the discharge motor 160 to rotate and open, and the sealed water sample flows into the diversion inclined plate 711 along the gap between the discharge gate leaf 150 and the discharge gate leaf 150. The floating algae in the water sample are screened and filtered through the screening filter 712, and are evaporated and dried by natural light. The detection personnel can regularly scrape off the floating algae to analyze the types and contents of the floating algae in the area. The floating oil and the water body flow into the sedimentation box frame 720 through the screening filter 712. If the water sample is colored or turbid and contains some other interfering substances, the flocculant is injected into the sedimentation box frame 720 through the liquid metering port 721, and the water sample is sedimented and stratified by standing still. The light-shielding plate 750 is controlled by the curtain cylinder 740 to fall, reducing the interference of light transmission in the screening box frame 710. The monitoring main body 760 measures the concentration of oil molecules in the water by the ultraviolet fluorescence method. The oil molecules are activated to the excited state under the irradiation of specific ultraviolet light. This excited state is very unstable and will quickly return to the ground state. During the process of returning to the ground state, radiation fluorescence will be generated. By controlling the emission wavelength of the ultraviolet light and selecting the specific fluorescence wavelength scattered back by the oil molecules, the types of floating oil and the concentration in the water can be analyzed regularly. Sampling is carried out regularly through the liquid separation port 770, which is convenient for the analysis and detection of other components of the water sample. The sampling and monitoring of floating algae and floating oil in dynamic and static water bodies are realized, with high automation, convenient pretreatment and classification of water samples, periodic sampling and monitoring of eutrophic water bodies, and convenient analysis and research on the current situation and change trend of water quality.
