[0061] In order 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.

[0062] like Figure 1-Figure 10 As shown, an environmental water body intelligent monitoring device comprises an exposed portion 2 disposed on the top of a floating body 1 and a water inlet 3 disposed on the bottom;

[0063] A platform 11 is provided in the floating body 1, a mounting frame 12 is fixedly mounted on the platform 11, and a mixing tank 4 (such as Figure 3 shown);

[0064] The mixed flow barrel 4 is provided with:

[0065] The dome portion 41 has a foot-shaped annular groove 411 at one end thereof in contact with the inner wall of the mixing barrel 4. The inclined surface of the foot-shaped annular groove 411 faces the axis. A flow-blocking composite portion 412 (such as Figure 4 shown);

[0066] The spiral heating element 42 is used to receive the liquid (such as Fig.10 shown);

[0067] The blocking composite part 412 includes a blocking group consisting of a plurality of triangular ridges located in the same plane and having increasing circumferential radii. There are multiple blocking groups, and the vertex of the triangular ridge of the next level corresponds to the center of the distance between two adjacent triangular ridges of the previous level.

[0068] Also includes a detection tube body 9 (such as Figure 5 As shown), it is fixedly mounted on the mixing barrel 4 to receive the liquid flow from the spiral heating element 42.

[0069] Specifically, the solution also includes a liquid injection part 5 installed at the top axis of the inner side of the exposed part 2, and the liquid outlet of the liquid injection part 5 corresponds to the dome of the dome part 41. A water pump 31 is arranged in the water inlet 3, and the hose at the output end of the water pump 31 passes through the carrier 11 and is connected to the second water inlet of the liquid injection part 5. Therefore, when performing the operation, the water pump 31 extracts a predetermined amount of seawater according to the control program, injects it into the top of the dome part 41 through the liquid injection part 5, and then flows down from the top of the dome part 41 to the flow-blocking composite part 412 for mixing.

[0070] Furthermore, a plurality of auxiliary agent tanks 6 are fixedly mounted on the carrier 11 and arranged in a circular array about the mounting frame 12, wherein: each three auxiliary agent tanks 6 form a group, and potassium dichromate, acid and sodium thiosulfate are stored respectively. The first liquid outlet pipes with circular water pumps provided on the plurality of auxiliary agent tanks 6 are respectively connected to the first water inlet group of the liquid injection part 5. Figure 3 It can be seen that there are three groups of auxiliary agent cabins 6 in the embodiment, and the purpose is to meet the needs of long-term online regular monitoring of the device. The monitored data is transmitted to the background through the network.

[0071] Secondly, the auxiliary agent tank 6 in the embodiment is provided with a circular water pump and a liquid level switch, that is, when the liquid level switch detects that the liquid level in the auxiliary agent tank 6 reaches a predetermined liquid level height, that is, the liquid is used up, it will automatically switch to another group of auxiliary agent tanks 6 for supply. After all three groups are used up, an early warning will be sent to the background, and the location will be sent.

[0072] It should be noted that the above-mentioned electronic components, control programs and operating systems are well known to those skilled in the art, and thus will not be described in detail.

[0073] Furthermore, a photovoltaic panel 10 is provided on the end face of the exposed portion 2, and the photovoltaic panel 10 is used to provide 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 for storing electrical energy, which belongs to a known technology and will not be described in detail.

[0074] In the above technology, the mixed liquid flows down from the dome portion 41 to the flow-blocking composite portion 412 for the first step of mixing, and then the spiral heating element 42 is used to achieve centrifugal mixing, thereby achieving full mixing of the mixed liquid, and the mixed liquid is injected into the detection tube body 9 to perform the detection. The liquid mixing requirements during the reaction process are fully considered to ensure the accuracy and reliability of the experimental results.

[0075] As an embodiment further provided by the present invention, Figure 2 As shown, the water inlet 3 is specifically a rectangular structure, and a concave leakage screen cover 32 is installed at the bottom;

[0076] A plurality of holes are provided on a first plane flush with the end surface of the water inlet 3 and a second plane adjacent to the first plane in the concave leakage screen cover 32;

[0077] A plastic hard pipe is fixedly installed at the water inlet of the water pump 31 and extends into the concave leakage screen cover 32.

[0078] Specifically, in the embodiment, the specially designed concave drain screen 32 can effectively separate particulate matter from the extracted seawater during the operation of the water pump 31. These particulate matter tend to clog the hollow holes on the first plane flush with the end face of the water inlet 3, while the multiple hollow holes on the adjacent second plane are relatively less likely to be clogged. In addition, the unique design of the concave drain screen 32 also brings other significant advantages. Its concave structure not only increases the contact area between the particulate matter and the hollow holes, improving the filtration efficiency, but also guides the direction of the water flow so that the water flow produces a certain eddy effect when passing through the hollow holes, which helps to further separate and remove fine particulate impurities.

[0079] It is worth noting that the layout of the hollow holes between the first plane and the second plane has been carefully calculated and optimized to ensure that even in the case of long-term continuous operation, a high flow capacity and a low risk of clogging can be maintained. This design not only prolongs the service life of the water pump 31, but also reduces the maintenance cost and time consumption caused by frequent cleaning of blockages.

[0080] In addition, the material selection of the concave drain screen 32 is also crucial. It is made of high-performance materials that are corrosion-resistant and wear-resistant, and can maintain stable performance in harsh marine environments, and is not easily affected by seawater corrosion or abrasion by particulate matter. The selection of this material not only improves the durability of the drain screen, but also ensures its reliability and safety in long-term use.

[0081] In summary, the specially designed concave leakage screen 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 blockage by seawater particulate matter and improves the filtering efficiency and operation stability of the water pump 31.

[0082] As another embodiment further provided by the present invention, Figure 3 and Figure 7 As shown, a conical cylinder 51 is provided in the liquid injection part 5, and the water outlet of the conical cylinder 51 is arranged opposite to the port of the liquid injection part 5;

[0083] The first water inlet is located at the connection between the conical cylinder 51 and the liquid injection part 5;

[0084] The second water inlet is located above the first water inlet, and an extension line of the second water inlet is tangent to the side wall of the conical cylinder 51 .

[0085] Specifically, in the embodiment, the liquid in the auxiliary tank 6 is introduced through the first water inlet, and the seawater enters through the second water inlet. Since the extension line of the second water inlet is tangent to the side wall of the conical cylinder 51, the introduced seawater will flow along the side wall of the conical cylinder 51, mix with the oxidant, and form a vortex. This process effectively optimizes the effect of pre-mixing.

[0086] In addition, it should be particularly pointed out that, in this embodiment, the auxiliary agent cabin 6 for storing sodium thiosulfate is directly connected to the mixed flow barrel 4 , and the water inlet is arranged at the inlet of the spiral heating element 42 .

[0087] It should be noted that the oxidizing agent is potassium dichromate and acid.

[0088] As another embodiment further provided by the present invention, Figure 6 and Figure 8 As shown, an arc-shaped top cover 43 fixedly connected to the dome 41 is centrally arranged in the mixing tank 4, and the port of the detection tube body 9 extends from the center of the spiral heating element 42 and is close to a water guide cone 44 arranged on the inner top of the arc-shaped top cover 43;

[0089] The outer edge of the arc-shaped top cover 43 is hinged with a plurality of extension rods 70 arranged in a circumferential array, and 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 barrel 4;

[0090] The detection tube body 9 is provided with a floating plate 71 arranged above the inlet of the spiral heating element 42, and a second connecting rod 72 is rotatably provided on the floating plate 71. The second connecting rod 72 is transmission-connected with the extension rod 70 so that the extension rod 70 moves up and flips with the floating plate 71 to cover the gap.

[0091] Specifically, a blower is fixedly installed in the water inlet 3 , and an output end of the blower is connected to the bottom of the mixing barrel 4 .

[0092] Further, after the liquid enters the spiral heating element 42, the spiral heating element 42 heats the liquid to about 150°C, and this heating process usually lasts for 2 hours. After two hours, the 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, will flow in a reverse spiral along the spiral heating element 42 and rise along the inner wall of the mixing barrel 4.

[0093] In this process, the floating plate 71 moves upward due to the wind force of the blower, and then pushes the extension rod 70 to flip, thereby blocking the distance between the arc-shaped top cover 43 and the inner wall of the mixing barrel 4. Since the first annular rubber web 8 is fixedly mounted on the inner wall of the arc-shaped top cover 43, and one end of the second annular rubber web 81 is fixed to the ends of multiple extension rods 70, and the other end is connected to the outer edge of the first annular rubber web 8, when the extension rod 70 flips over to block, the second annular rubber web 81 will open to intercept the liquid that rises against the inner wall of the mixing barrel 4. In this way, the liquid will flow along the second annular rubber web 81 to the first annular rubber web 8, and finally converge at the water guide cone 44 and enter the detection tube body 9. At the same time, the automatic exhaust valve 53 remains open.

[0094] As another embodiment further provided by the present invention, Figure 8 As shown, a guide rail member 73 arranged near the end of the detection tube body 9 is fixedly mounted on the detection tube body 9, and a head ball seat 76 which is kept centered by equidistant springs 75 on both sides is slidably arranged on the guide rail member 73;

[0095] The end of the extension rod 70 is rotatably connected to a third connecting rod 74, the third connecting rod 74 is an L-shaped structure, and the angle of the L-shaped structure is an obtuse angle;

[0096] A universal ball 741 is fixedly disposed at the end of the third connecting rod 74, and the universal ball 741 is rotatably connected to the head ball seat 76;

[0097] The second connecting rod 72 is rotatably disposed on the third connecting rod 74 and is close to the side where the angle is located.

[0098] Specifically, in the embodiment, when the floating plate 71 is moved upward by the wind force of the blower, the second connecting rod 72 pushes the third connecting rod 74 to approach the inner wall of the mixing barrel 4. At this time, the equidistant springs 75 fixed on both sides of the header 76 are deformed by 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 barrel 4. Since the first annular rubber soft web 8 is fixedly mounted 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 ends of the plurality of 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 fitting the liquid rising from the inner wall of the mixing barrel 4. As the second annular rubber soft web 81 opens, its soft and elastic material can fit closely to the inner wall of the mixing barrel 4, forming a temporary liquid barrier. As a result, the liquid will be blocked by the liquid barrier after entering, so that the untreated liquid will not overflow or leak directly, while ensuring the sealing and operating efficiency of the entire system.

[0099] At the same time, when the floating plate 71 descends due to the weakening or cessation of wind force, 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 wing 81 also shrinks and fits again to the end of the extension rod 70, preparing for the next shielding action.

[0100] As another embodiment further provided by the present invention, Figure 3 , Figure 5 and Fig. 9 As shown, the end of the detection tube body 9 is fixedly connected to a micro-drainage pump 52 , and the detection tube body 9 is fixedly connected to an automatic exhaust valve 53 arranged close to the carrier 11 ; and the micro-drainage pump 52 and the automatic exhaust valve 53 are both located in the water inlet 3 .

[0101] Specifically, after the COD value detection is completed, the micro drainage pump 52 is started to pump out the liquid in the detection tube body 9.

[0102] The environmental water body intelligent detection method provided by the above device includes the following steps:

[0103] S01. After arriving at the predetermined position, the water pump 31 is started to pump seawater into the conical cylinder 51. At the same time, the auxiliary tank 6 containing potassium dichromate and acid uses the circular water pump thereon to pump potassium dichromate and acid into the conical cylinder 51 according to the predetermined measurement. Since the extension line of the second water inlet is tangent to the side wall of the conical cylinder 51, the introduced seawater will flow along the side wall of the cylinder and mix with the oxidant to form a vortex. This process significantly improves the effect of pre-mixing.

[0104] SO2, potassium dichromate, acid and seawater flow out of the conical cylinder 51, flow downward along the dome portion 41, and mix at the flow-blocking composite portion 412.

[0105] S03. The liquid flows into the spiral heating element 42, which heats the liquid to about 150°C. Usually, a heating time of 2 hours is required.

[0106] S04. The auxiliary agent tank 6 filled with sodium thiosulfate pumps the liquid into the spiral heating element 42 through the circular water pump thereon.

[0107] S05. After two hours, the heating is stopped and sodium thiosulfate is added to the system. Next, the blower is started, and the liquid, under the action of the blower, will flow in a reverse spiral along the spiral heating element 42 and rise along the inner wall of the mixing barrel 4.

[0108] S06. Under the action of air blowing, the floating plate 71 moves upward, and the second connecting rod 72 pushes the third connecting rod 74 to approach the inner wall of the mixing barrel 4. At this time, the equidistant springs 75 fixed on both sides of the header seat 76 are deformed due to pressure. With the movement of the third connecting rod 74, the push extension rod 70 is flipped over and blocked, and the second annular rubber web 81 opens to intercept the liquid that rises along the inner wall of the mixing barrel 4. In this way, the liquid will flow along the second annular rubber web 81 to the first annular rubber web 8, and finally converge at the water guide cone 44 and enter the detection tube body 9. At the same time, the automatic exhaust valve 53 remains open.

[0109] S07, measuring the height of the liquid level remaining after reduction in the detection tube body 9 to determine the COD value. The higher the COD value, the more organic matter content in the water body, and the higher the pollution degree.

[0110] It should be noted that the method for determining the COD value is common technical knowledge among those skilled in the art and will not be disclosed in detail.

[0111] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that 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 above 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.
