Technical Field

[0001] This invention relates to the field of water environment monitoring technology, and in particular to an environmental monitoring device for aquatic organism assessment. Background Technology

[0002] With the rapid development of industry, especially the chemical industry, toxic and hazardous materials frequently cause environmental pollution incidents during production, storage, and transportation, entering water bodies and causing serious damage to the aquatic ecosystems on which humans depend for survival. In order to ensure the safety of water bodies, especially drinking water sources, and to respond quickly to various sudden water pollution incidents, the development of technologies for rapid and accurate assessment of the toxicity of various pollutants is particularly urgent and important.

[0003] To address this, a water environment monitoring device for aquatic biological assessment, such as patent number CN211528382U, has been developed.

It can also simulate the ecological impact of rainfall on the corresponding water body. Stirring can make the sludge and water more evenly distributed. Temperature and ventilation can be adjusted as needed. However, while solving the above problems, this device has the following drawbacks: it can only monitor the water environment when the liquid in the simulated tank is static or fluctuating within a small range. It cannot effectively monitor the water environment under simulated flowing water conditions, let alone the impact of upstream liquid containing different proportions of sludge on the water environment of the monitoring area under simulated flowing water conditions.

This allows for the simulation and monitoring of the water environment in the simulation tank. Simultaneously, while the circulation simulation mechanism is transporting the liquid, the sludge content in the liquid is filtered through a filtration mechanism as required, or the sludge at the bottom of the flow chamber is pumped into the circulation pipe of the circulation simulation mechanism through a sewage pipe and connecting pipe.

[0020] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] An environmental monitoring device for aquatic organism assessment includes a testing tank 1 and a simulation tank 2 disposed inside the testing tank 1. The simulation tank 2 is equipped with a blower 3 and a temperature control box 4. The testing tank 1 and the simulation tank 2 are connected by a radially arranged fixing plate 14. An arc-shaped plate 5 is also provided in the cavity between the testing tank 1 and the simulation tank 2, which divides it into multiple sets of flow chambers 6. One end of the arc-shaped plate 5 is connected to the fixing plate 14, and the other end of the arc-shaped plate 5 has a connecting opening I7 between it and the fixing plate 14. Any two adjacent sets of connecting openings I7 are located on opposite sides of the fixing plate 14. A connecting opening II8 is provided on the side wall of the simulation tank 2, which communicates with the innermost flow chamber 6.

[0022] A feeding mechanism 10 is provided on the top of the testing barrel 1, and a circulation simulation mechanism 11 is provided on the outside of the testing barrel 1. The circulation simulation mechanism 11 includes a box 1101. One end of the box 1101 is connected to the outermost flow chamber 6 through a pipe 1102 on which a sewage pump 1103 is installed. A grid plate 1104 is provided inside the box 1101 to divide it into two sets of installation chambers 1105. A three-way pipe 11106 with its discharge end extending into the corresponding installation chamber 1105 is provided on the pipe 1102. A filter mechanism 1107 is provided on the discharge end of the three-way pipe I1106 inside the mounting cavity 1105. A three-way pipe II1108 connected to the corresponding mounting cavity 1105 is also provided on the outside of the box body 1101. A circulation pipe 1109 extending into the simulation tank 2 is provided on the three-way pipe II1108. A sewage discharge pipe 1110 is provided on the circulation pipe 1109. A connecting pipe 1111 connected to the sewage discharge pipe 1110 is provided at the bottom of the flow cavity 6. A sludge pump 1112 is provided on the sewage discharge pipe 1110.

[0023] In this embodiment, solenoid valves are provided on the discharge end of the three-way pipe I106 that communicates with the mounting cavity 1105 and the inlet end of the three-way pipe II1108 that communicates with the mounting cavity 1105. The opening and closing of the corresponding discharge end and inlet end of the three-way pipe I1106 and the three-way pipe II1108 can be adjusted by the solenoid valves. A check valve is provided on the sewage pipe 1110 to prevent liquid on the circulation pipe 1109 from flowing back into the sewage pipe 1110.

[0024] In this embodiment, a box 12 is provided on the lower half of the side wall of the detection tank 1, and a water outlet opening is provided on the side wall of the detection tank 1 to connect the box 12 with the outer flow cavity 6.

[0025] like Figure 1 , 4As shown, a sealing mechanism 9 is provided at the connecting opening II8. The sealing mechanism 9 includes two sets of angle steels 91, which are located on both sides of the connecting opening II8 and fixedly connected to the inner wall of the simulation tank 2. An arc-shaped sealing plate 92 is also provided inside the simulation tank 2 to seal the connecting opening II8. The two ends of the sealing plate 92 are located in the openings formed between the corresponding angle steels 91 and the inner wall of the simulation tank 2. The sealing mechanism 9 prevents liquid in the simulation tank 2 from flowing into the flow chamber 6. At the same time, the opening degree of the connecting opening II8 can be adjusted by moving the sealing plate 92 upward, so that the liquid in the simulation tank 2 can flow into the flow chamber 6. The flow rate of the outflowing liquid can also be controlled in this way.

[0026] The simulation tank 2 has a support plate 13 at the top. The feeding mechanism 10 includes a barrel-shaped shell 101 mounted on the support plate 13. The shell 101 is located above the opening of the simulation tank 2. The blower 2 and the temperature control box 3 are both located at the bottom of the shell 101. The bottom of the shell 101 has a discharge pipe 102. The top of the shell 101 has a water inlet pipe 103 and a sludge pipe 104. The top of the shell 101 also has a motor 105. The output shaft of the motor 105 passes through the shell 101 and extends into the simulation tank 2. The output shaft of the motor 105 inside the shell 101 has a stirring paddle I106. The output shaft of the motor 105 inside the simulation tank 2 has a stirring paddle II107.

[0027] The filter mechanism 1107 is disposed within the upper mounting cavity 1105. The filter mechanism 1107 is a filter bag, the opening of which is fitted onto the discharge end of the three-way pipe 11106 and secured with a clamp. The top of the housing 1101 has an operating opening communicating with the upper mounting cavity 1105, and a cover is provided at the operating opening. The filter mechanism 1107 within the upper mounting cavity 1105 can be replaced or cleaned through the opened operating opening.

[0028] In this embodiment, the bottom end of the simulation barrel 2 is fixedly connected to the inner bottom wall of the detection barrel 1, and the edge of the fixing plate 14 is fixedly connected to the outer wall of the simulation barrel 2 and the corresponding side wall of the detection barrel 1. The detection barrel 1, the simulation barrel 2 and the arc plate 5 are coaxially arranged.

[0029] This device is also equipped with an external controller, which can be programmed by those skilled in the art to control the internal components. During use, water and sludge enter the housing 101 through the inlet pipe 103 and the sludge pipe 104. The output shaft of the motor 105 drives the stirring paddles I106 and II107 to rotate, thereby initially stirring and mixing the liquid and sludge in the housing 101. At the same time, the mixed liquid enters the simulation tank through the outlet pipe 102, and is then stirred and mixed again by the rotating stirring paddle II107 to improve the mixing efficiency and make the water and sludge evenly distributed in the simulation tank 2 to simulate the aquatic environment. Meanwhile, people can monitor the internal working conditions in real time through the monitoring probe and monitoring camera installed in the simulation tank 2. At the same time, the blower 3 and the temperature control box 4 can be controlled to control the ventilation, air exchange volume and temperature inside the simulation tank 2. The living status of the organisms in the simulation tank 2 under different environments and the impact of the sewage environment on them can be monitored. In addition, water can be sprayed into the simulation tank 2 to monitor the living status of the organisms in the simulation tank 2 under rainfall and the impact of the sewage environment on them.

[0030] When simulating a flowing water state, by opening the connecting opening II8, the liquid in the simulation tank 2 can enter the inner flow chamber 6 through the connecting opening II8. Then, the liquid in the two adjacent sets of flow chambers 6 can flow through the connecting opening I7, and finally the liquid flows into the outermost flow chamber 6. At this time, the sewage pump 1103 enters the three-way valve I1106 through the pipe 1102, the box 12 and the water outlet. 1. If the simulated upstream water content and sludge amount are small at this time, then the discharge end above the three-way valve I1103 and the three-way valve II1 are opened. The solenoid valve at the feed end of pipe 1102 allows liquid to be drawn from pipe 1102 and enter the upper mounting cavity 1105 through three-way valve I1106. After being filtered by the filter mechanism 1107, it then enters the circulation pipe 1109 through the discharge end of three-way valve II1108. This circulates the liquid with a low sludge content to the simulation tank 2, creating a flowing water state between the simulation tank 2 and the flow chamber 6 for simulation monitoring. 2. When the upstream water content and sludge amount are at a normal level, the discharge end below three-way valve I1106 and the three-way valve are opened. The solenoid valve on the feed end below valve II1108 allows liquid drawn from pipe 1102 to enter the lower mounting cavity 1105 via three-way valve I1106, and then enters the circulation pipe 1109 via the discharge end below three-way valve II1108. This circulates the liquid with normal sludge content to the simulation tank 2, creating a flowing water state between the simulation tank 2 and the flow chamber for simulation monitoring. 3. When simulating a large amount of upstream water and sludge, this method is basically the same as the second method, except that the sludge pump 1112 discharges wastewater... Pipe 1110 and connecting pipe 1111 draw the sediment accumulated at the bottom of multiple flow chambers 6 along with a small amount of liquid from the circulation pipe 1109, and mix it with the liquid introduced into the circulation pipe 1109 from the installation chamber 1105 to increase the mud content in the liquid. At the same time, the liquid is introduced into the simulation tank 2 through the circulation pipe 1109, so that the simulation tank 2 and the flow chambers 6 achieve a living water state for simulation monitoring, so as to simulate the living state of aquatic organisms under different environments and the impact of the sewage environment on them when liquid with different mud contents from upstream enters the simulation tank 2.

[0031] This invention simulates the flow of liquid in a simulated tank 2 through a connecting opening II8 into a flow chamber 6, creating a serpentine flow. The liquid is then reintroduced into the simulated tank 2 by a circulation simulation mechanism 11, thus forming a flowing, living water environment. This allows for the simulation and monitoring of the water environment in the simulated tank 2. Simultaneously, while the circulation simulation mechanism 11 is transporting the liquid, the sludge content in the liquid is filtered through a filtration mechanism 1107 as required. Alternatively, sludge from the bottom of the flow chamber 6 can be pumped into the circulation pipe 1109 of the circulation simulation mechanism 11 through a drain pipe 1110 and a connecting pipe 1111. Then, the liquid under these different conditions is sequentially reintroduced into the simulated tank 2 as required, simulating liquids with different sludge contents entering the simulated tank 2 to monitor their impact on the downstream water environment. This allows for multi-faceted simulation of the living conditions of aquatic organisms under different environments and the impact of wastewater on them.

[0032] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
