Description

A smart monitoring device and detection method for environmental water bodies Technical Field

[0001] This invention relates to the field of water quality testing technology, specifically to an intelligent monitoring device and testing method for environmental water bodies. Background Technology

[0002] COD (Chemical Oxygen Demand) is an indicator used to measure the degree of organic pollution in water bodies. The main purpose of COD testing is to determine the total amount of organic matter in a water sample, thereby assessing the degree of water pollution. COD testing is commonly used in wastewater treatment, environmental monitoring, and water quality management.

[0003] Reference Publication No.: CN116359534A, Publication Date: 2023-06-30, discloses a seawater COD detection device, including a main housing, a main pipe fixedly installed inside the main housing, and multiple sealing pipes connected to the outside of the main pipe. A sealing plate is rotatably connected to one side of each sealing pipe via a hinge. This invention relates to the field of seawater COD detection technology. In this specific seawater COD detection device, by sliding a suction rod inside a suction column, the reagents required for different methods of seawater COD detection can be drawn into the feed box. Furthermore, through the interaction between the sealing suction rod and the adjusting rod, the adjusting rod can rotate to the required reagent adjustment frame position, allowing the adjusting plate to adjust the height of the sealing suction rod. This ensures that the reagents required for different detection methods flow into the transparent measuring tube for uniform measurement, thereby improving the overall convenience of controlling the required amount of reagents and samples in the seawater COD detection device.

[0004] In the prior art, including the aforementioned patents, the following steps are required to perform COD detection:

[0005] 1. Mix seawater with an oxidant (such as potassium dichromate) and an acid, and then heat the mixture to oxidize the organic matter in the water sample;

[0006] 2. Titrate the mixture after the reaction with a reducing agent (such as sodium thiosulfate) and measure the amount of reducing agent consumed during the reaction.

[0007] 3. Calculate the COD value based on the amount of reducing agent consumed to reflect the content of organic matter in the water sample.

[0008] During the above steps, the collected seawater and reaction liquid need to be thoroughly mixed. Conventional mixing methods include centrifugation and shaking. However, the technology provided by the above patent clearly lacks a mixing process. The core of the design lies in the extraction and input of the mixed liquid. Summary of the Invention

[0060] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0061] As shown in Figures 1-10, an intelligent monitoring device for environmental water bodies includes an exposed part 2 at the top of the floating part 1 and a water inlet 3 at the bottom.

[0062] A platform 11 is provided inside the floating body 1, and a mounting frame 12 is fixedly installed on the platform 11. A mixing tank 4 is fixedly installed on the mounting frame 12 (as shown in Figure 3).

[0063] The mixing tank 4 is equipped with:

[0064] The dome 41 has a support-shaped annular groove 411 at one end that contacts the inner wall of the mixing tank 4. The inclined surface of the support-shaped annular groove 411 faces the axis. A flow-blocking composite part 412 with the same outline as the support-shaped annular groove 411 is provided inside the support-shaped annular groove 411 (as shown in Figure 4).

[0065] The spiral heating element 42 is used to receive liquid passing through the flow-blocking composite part 412 (as shown in Figure 10);

[0066] The flow-blocking composite part 412 includes a flow-blocking group composed of multiple triangular ridges located on the same plane with increasing circumferential radius. The number of flow-blocking groups is multiple, and the vertex of the next level triangular ridge corresponds to the center of the distance between two adjacent triangular ridges of the previous level.

[0067] It also includes a detection tube 9 (as shown in Figure 5), which is fixedly installed on the mixing tank 4 to receive the liquid flowing from the spiral heating element 42.

[0068] Specifically, the design also includes an injection unit 5 installed on the inner top axis of the exposed section 2, with the outlet of the injection unit 5 corresponding to the dome of the dome 41. A water pump 31 is installed inside the inlet 3, and the hose at the output end of the water pump 31 passes through the platform 11 and connects to the second inlet of the injection unit 5. Therefore, during operation, the water pump 31 extracts a predetermined amount of seawater according to the control program, injects it into the top of the dome 41 through the injection unit 5, and then flows down from the top of the dome 41 to the flow-blocking composite section 412 for mixing.

[0069] Furthermore, multiple auxiliary agent compartments 6 arranged in a circular array around the mounting frame 12 are fixedly installed on the platform 11. Each group of three auxiliary agent compartments 6 stores potassium dichromate, acid, and sodium thiosulfate, respectively. The first outlet pipes equipped with circular water pumps on the multiple auxiliary agent compartments 6 are connected to the first inlet group of the injection section 5. Referring to Figure 3, there are three groups of auxiliary agent compartments 6 in this embodiment, the purpose of which is to meet the long-term online timed monitoring requirements of this device. The monitored data is transmitted to the backend via a network.

[0070] Secondly, the auxiliary agent tank 6 in the embodiment is equipped with a circular water pump and a liquid level switch. When the liquid level switch detects that the liquid level in the auxiliary agent tank 6 has reached the predetermined liquid level height, that is, after the liquid is used up, it will automatically switch to another set of auxiliary agent tanks 6 for supply. After all three sets are used up, an early warning will be sent to the background and the location will be sent.

[0071] It should be noted that the aforementioned electronic components, control programs, and operating systems are all well-known to those skilled in the art, and therefore will not be described in detail.

[0072] Furthermore, a photovoltaic panel 10 is installed on the end face of the exposed part 2, which provides a stable power supply for the entire device. It should be noted that the photovoltaic panel 10 is actually a photovoltaic power supply device with a lithium battery that stores electrical energy, which is a well-known technology and will not be described in detail.

[0073] In the above technology, the mixed liquid flows down from the dome 41 to the flow-blocking composite section 412 for the first stage of mixing, and then centrifugal mixing is achieved using the spiral heating element 42, thereby ensuring thorough mixing of the liquid. The mixed liquid is then injected into the detection tube 9 for detection. This fully considers the liquid mixing requirements during the reaction process, ensuring the accuracy and reliability of the experimental results.

[0074] As a further embodiment of the present invention, as shown in FIG2, the water inlet 3 is specifically a rectangular structure, and a concave mesh cover 32 is installed at the bottom;

[0075] Multiple perforations are provided on the first plane flush with the end face of the water inlet 3 and the second plane adjacent to the first plane in the concave mesh cover 32.

[0076] A plastic rigid pipe is fixedly installed at the inlet of the water pump 31, extending into the concave mesh cover 32.

[0077] Specifically, in the embodiments, the specially designed concave mesh cover 32 can effectively separate particulate matter from the pumped seawater during the operation of the pump 31. These particulate matter tends to clog the perforations on the first plane flush with the end face of the inlet 3, while the multiple perforations on the adjacent second plane are relatively less prone to clogging. In addition, the unique design of the concave mesh cover 32 also brings other significant advantages. Its concave structure not only increases the contact area between particulate matter and perforations, improving filtration efficiency, but also guides the water flow direction, causing a certain vortex effect when the water flows through the perforations, which helps to further separate and remove fine particulate impurities.

[0078] It is worth noting that the perforation layout between the first and second planes has been carefully calculated and optimized to ensure high flow capacity and low risk of clogging even under long-term continuous operation. This design not only extends the service life of the water pump 31 but also reduces maintenance costs and time consumption caused by frequent cleaning of blockages.

[0079] Furthermore, the choice of material for the concave mesh cover 32 is also crucial. It is made of high-performance, corrosion-resistant and wear-resistant materials, enabling it to maintain stable performance in harsh marine environments and resisting corrosion from seawater or abrasion from particulate matter. This material selection not only enhances the durability of the mesh cover but also ensures its long-term reliability and safety.

[0080] In summary, the specially designed concave mesh cover 32 in the embodiment plays a key role in the water pump 31 system. Through its unique structure and material selection, it effectively solves the problem of seawater particulate matter clogging and improves the filtration efficiency and operational stability of the water pump 31.

[0081] As a further embodiment of the present invention, as shown in Figures 3 and 7, a conical cylinder 51 is provided inside the injection section 5, and the outlet of the conical cylinder 51 is arranged opposite to the port of the injection section 5.

[0082] The first water inlet is located at the connection between the conical cylinder 51 and the liquid injection section 5;

[0083] The second inlet is located above the first inlet, and the extension line of the second inlet is tangent to the side wall of the conical cylinder 51.

[0084] Specifically, in this embodiment, the liquid in the aerator compartment 6 is introduced through the first inlet, while seawater enters through the second inlet. Since the extension line of the second inlet is tangent to the side wall of the conical cylinder 51, the introduced seawater flows along the side wall of the conical cylinder 51, mixes with the oxidant, and forms a vortex. This process effectively optimizes the pre-mixing effect.

[0085] In addition, it should be noted that in this embodiment, the admixture chamber 6 for storing sodium thiosulfate is directly connected to the mixing tank 4, and the water inlet is located at the inlet of the spiral heating element 42.

[0086] It should be noted that the oxidizing agents are potassium dichromate and acid.

[0087] As a further embodiment of the present invention, as shown in Figures 6 and 8, an arc-shaped top cover 43 is centrally located inside the mixing tank 4 and is fixedly connected to the dome 41. The port of the detection tube 9 extends from the center of the spiral heating element 42 and is close to the top of the inner side of the arc-shaped top cover 43, where a water guide cone 44 is provided.

[0088] The outer edge of the arc-shaped top cover 43 is hinged with multiple extension rods 70 arranged in a circular array. The length of the extension rods 70 is equal to the distance between the arc-shaped top cover 43 and the inner wall of the mixing tank 4.

[0089] A floating plate 71 is provided on the detection tube 9, which is arranged above the inlet of the spiral heating element 42. A second connecting rod 72 is rotatably provided on the floating plate 71. The second connecting rod 72 is connected to the extension rod 70 in a transmission manner, so that the extension rod 70 moves up and flips with the floating plate 71 to block the gap.

[0090] Specifically, a blower is fixedly installed inside the water inlet 3, and its output end is connected to the bottom of the mixing tank 4.

[0091] Furthermore, after the liquid enters the spiral heating element 42, the spiral heating element 42 heats the liquid to approximately 150°C, and this heating process typically lasts for 2 hours. After two hours, heating is stopped, and sodium thiosulfate is added to the system. Subsequently, the blower is started, and the liquid, under the action of the blower, flows in a reverse spiral along the spiral heating element 42 and rises against the inner wall of the mixing tank 4.

[0092] During this process, the floating plate 71 moves upward due to the force of the blower, which in turn pushes the extension rod 70 to flip, thereby blocking the gap between the arc-shaped top cover 43 and the inner wall of the mixing tank 4. Since the first annular rubber soft web 8 is fixedly installed on the inner wall of the arc-shaped top cover 43, and one end of the second annular rubber soft web 81 is fixed to the end of the multiple extension rods 70, while the other end is connected to the outer edge of the first annular rubber soft web 8, the second annular rubber soft web 81 will open after the extension rod 70 flips to block, intercepting the liquid rising against the inner wall of the mixing tank 4. In this way, the liquid will flow along the second annular rubber soft web 81 to the first annular rubber soft web 8, and finally collect in the guide cone 44 and enter the detection tube 9. At the same time, the automatic exhaust valve 53 remains open.

[0093] As a further embodiment of the present invention, as shown in FIG8, a guide rail 73 is fixedly installed on the detection tube 9 and arranged near the port of the detection tube 9. A ball head seat 76, which is slidably disposed on the guide rail 73 and is kept in the center by equidistant springs 75 on both sides.

[0094] The end of the extension rod 70 is rotatably connected to a third connecting rod 74, which has an L-shaped structure and the included angle of the L-shaped structure is an obtuse angle.

[0095] The end of the third connecting rod 74 is fixedly provided with a universal ball 741, which is rotatably connected to the ball head seat 76;

[0096] The second connecting rod 72 is rotatably mounted on the third connecting rod 74 and is located near the side where the included angle is located.

[0097] Specifically, in this embodiment, when the floating plate 71 moves upward under the force of the blower, the second connecting rod 72 pushes the third connecting rod 74 closer to the inner wall of the mixing tank 4. At this time, the equidistant springs 75 fixed on both sides of the ball bearing 76 are deformed under pressure. As the third connecting rod 74 moves, it pushes the extension rod 70 to flip, thereby closing the gap between the arc-shaped top cover 43 and the inner wall of the mixing tank 4. Since the first annular rubber soft web 8 is fixedly installed on the inner wall of the arc-shaped top cover 43, and one end of the second annular rubber soft web 81 is fixed to the end of the multiple extension rods 70, and the other end is connected to the outer edge of the first annular rubber soft web 8, when the extension rod 70 flips and closes the gap, the second annular rubber soft web 81 will open, effectively intercepting and adhering to the liquid rising from the inner wall of the mixing tank 4. As the second annular rubber soft web 81 opens, its soft and elastic material can tightly adhere to the inner wall of the mixing tank 4, forming a temporary liquid barrier. This ensures that the liquid entering the system is blocked by the liquid barrier, preventing untreated liquid from overflowing or leaking directly, while also ensuring the sealing and operational efficiency of the entire system.

[0098] Simultaneously, when the floating plate 71 descends due to weakened or stopped wind, the equidistant spring 75 gradually returns to its original state, pushing the third connecting rod 74 and the extension rod 70 back to their initial positions. During this process, the second annular rubber soft web 81 also retracts and re-attaches to the end of the extension rod 70, preparing for the next blocking action.

[0099] As a further embodiment of the present invention, as shown in Figures 3, 5 and 9, a miniature drainage pump 52 is fixedly connected to the end of the detection tube 9, and an automatic air vent valve 53 arranged near the platform 11 is fixedly connected to the detection tube 9; and both the miniature drainage pump 52 and the automatic air vent valve 53 are located inside the water inlet 3.

[0100] Specifically, after the COD value test is completed, the miniature drainage pump 52 is started to extract the liquid in the test tube 9.

[0101] The intelligent environmental water detection method based on the above-mentioned device includes the following steps:

[0102] S01. Upon reaching the designated position, the water pump 31 starts, drawing seawater into the conical cylinder 51. Simultaneously, the auxiliary tank 6, containing potassium dichromate and acid, uses its circular water pump to draw potassium dichromate and acid into the conical cylinder 51 according to a predetermined metering. Because the extension line of the second inlet is tangent to the side wall of the conical cylinder 51, the introduced seawater flows along the side wall of the cylinder and mixes with the oxidant, forming a vortex. This process significantly improves the pre-mixing effect.

[0103] SO2, potassium dichromate, acid, and seawater flow out from the conical cylinder 51, flow downwards along the dome 41, and mix at the flow-blocking composite section 412.

[0104] S03, the liquid flows into the spiral heating element 42, which heats the liquid to about 150°C, usually requiring 2 hours of heating time.

[0105] S04, The auxiliary tank 6 containing sodium thiosulfate draws the liquid into the spiral heating element 42 through a circular water pump.

[0106] S05. Two hours later, heating is stopped, and sodium thiosulfate is added to the system. Then, the blower is started, and the liquid flows in a reverse spiral along the spiral heating element 42 under the action of the blower, and rises against the inner wall of the mixing tank 4.

[0107] S06. Under the action of the blower, the floating plate 71 moves upward, and the second connecting rod 72 pushes the third connecting rod 74 closer to the inner wall of the mixing tank 4. At this time, the equidistant springs 75 fixed on both sides of the ball joint 76 deform due to pressure. As the third connecting rod 74 moves, the push extension rod 70 flips and blocks, and the second annular rubber soft web 81 opens, intercepting the liquid rising against the inner wall of the mixing tank 4. In this way, the liquid will flow along the second annular rubber soft web 81 to the first annular rubber soft web 8, and finally collect in the guide cone 44 and enter the detection tube 9. At the same time, the automatic exhaust valve 53 remains open.

[0108] S07. Measure the remaining liquid level in the detection tube 9 after reduction to determine the COD value. The higher the COD value, the more organic matter is present in the water, and the higher the degree of pollution.

[0109] It should be noted that the method for determining COD value is common knowledge to those skilled in the art and will not be disclosed in detail.

[0110] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
