Description

TECHNICAL FIELD

[0002] Water quality monitoring is a process of monitoring and measuring the types of pollutants in water, the concentrations of various pollutants and their trends, and evaluating water quality. The monitoring range is very wide, including both unpolluted and polluted natural water (rivers, lakes, seas and underground water) and various industrial wastewater. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand, etc.; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides, etc.

The regular water taking method is troublesome, the water taking point is single, and the area is limited, which affects the overall evaluation standard of water quality. The regular water taking method can only detect the current time period of water taking, and the change process of water quality cannot be known when it is not the sampling period, resulting in that the detection data is not comprehensive and accurate. Therefore, we need to solve this problem in a timely manner. SUMMARY

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0043] Embodiment 1: refer to the description attached Figures 1-10 The water quality monitoring system of multi-source data fusion according to an embodiment of the present application comprises a positioning module, a memory module, a communication module, a water quality safety evaluation module, a database, and a housing component 1.

[0044] As shown in Figure 1 , the housing component 1 comprises a floating cylinder 101 and an underwater filter cylinder 102. The top of the floating cylinder 101 is connected with a cover 103. The cover 103 is opened, and then the sampling component 3 is inserted into the toothed turntable 206. The outer side of the underwater filter cylinder 102 is hinged with a door plate. Through the setting of the door plate, after the sampling component 3 completes sampling, the door plate can be opened, and the sampling component 3 that has completed sampling can be taken out. The outer side of the floating cylinder 101 is fixedly installed with an arc-shaped protective ring 104. As shown in Figure 10 , the bottom of the arc-shaped protective ring 104 is bonded with a first buoyancy bag 109. The buoyancy of the first buoyancy bag 109 makes the floating cylinder 101 float on the water surface. The outer side of the arc-shaped protective ring 104 is fixedly installed with a reinforcing frame 105. The inside of the reinforcing frame 105 is provided with a damping spring 106. One end of the damping spring 106 is fixedly connected with a movable slide rod 107. The movable slide rod 107 is in sliding connection with the reinforcing frame 105. One end of the movable slide rod 107 is fixedly installed with an elastic outer ring 108. The inside of the underwater filter cylinder 102 is provided with a transmission mechanism 2. In the case of flowing water, the first buoyancy bag 109 drives the floating cylinder 101 to float. When the housing component 1 floats towards the fishpond pool wall, the elastic outer ring 108 contacts the pool wall, so that the movable slide rod 107 extrudes the damping spring 106, and the damping spring 106 is buffered, thereby preventing the housing component 1 from being damaged.

[0045] As shown in Figure 2As shown, the transmission mechanism 2 includes a prefabricated water storage tank 201. Miniature sponge columns 202 are inserted inside the prefabricated water storage tank 201. The miniature sponge columns 202 are extremely small, so when water flows into the prefabricated water storage tank 201, it forms water droplets, allowing the prefabricated water storage tank 201 to sink slowly. A connecting rope 203 is fixedly connected to the top of the prefabricated water storage tank 201. An I-shaped roller 204 is wound around the outside of the connecting rope 203. The rotation of the I-shaped roller 204 is connected to the inner wall of the upper float 101. There is a certain resistance at the connection between the I-shaped roller 204 and the upper float 101, so that the miniature sponge columns 202 can pull the I-shaped roller 204 slowly when sinking. The rotating I-shaped drum 204 has a gear 205 fixedly installed on one side. The gear 205 meshes with a toothed turntable 206 on its outer side. The toothed turntable 206 is rotatably connected to the inner side of the upper float 101. The sampling component 3 is inserted into the inner side of the toothed turntable 206. The bottom of the prefabricated water tank 201 is bonded with a second buoyancy bladder 207. The second buoyancy bladder 207 provides the prefabricated water tank 201 with a certain buoyancy, so that it is initially held at the top of the underwater filter 102. The storage tray 501 limits the position of the prefabricated water tank 201. Only when the water in the prefabricated water tank 201 increases will the weight of the prefabricated water tank 201 increase and it will gradually sink.

[0046] like Figure 2 As shown, a sealing component 4 is fixedly installed on the inner side of the upper float 101, and a storage component 5 is fixedly installed on the inner side of the prefabricated water storage tank 201.

[0047] Regarding the above technical solution, it should be noted that when actually using this invention, the cover 103 is opened, and then the sampling component 3 is inserted into the toothed turntable 206. The underwater filter 102 is placed in the fishpond. Using the buoyancy of the first buoyancy bag 109, the upper float 101 floats on the water surface. When water flows into the underwater filter 102, the water will wet the micro sponge column 202. As the water content of the micro sponge column 202 gradually increases, the excess water will form water droplets that fall into the prefabricated water storage tank 201. The weight of the prefabricated water storage tank 201 gradually increases, causing the prefabricated water storage tank 201 to gradually sink. When the prefabricated water storage tank 201 sinks, the connecting rope 203 pulls the I-shaped roller 204 to rotate, causing the gear 205 to drive the toothed turntable 206 to rotate. When the sampling component 3 is aligned with the corresponding ring 403, the sampling component 3 will fall, and then the water inside the micro sponge column 202 will be sampled.

[0048] Example 2: As Figure 4 As shown, the sampling component 3 includes a sampling tube 301, such as Figure 5 As shown, a movable slider 302 is slidably connected to the inner side of the sampling tube 301, and a movable sealing plate 303 is fixedly installed on one side of the movable slider 302.

[0049] like Figure 5 As shown, a water inlet 304 is provided on the inner side of the movable sealing plate 303. A first magnet 305 is attached to the inner side of the water inlet 304. A third buoyancy bladder 306 is attached to the bottom of the movable sealing plate 303. When water is injected into the sampling tube 301, the water level in the sampling tube 301 rises, causing the third buoyancy bladder 306 to float, thereby driving the movable sealing plate 303 to float.

[0050] like Figure 6 As shown, a positioning rod 307 is fixedly installed on the top of the sampling tube 301. A second magnet 308 is bonded to the outside of the positioning rod 307. A first sealing ring 309 is bonded to the top of the second magnet 308. A second sealing ring 310 is bonded to the inside of the sampling tube 301. The positioning rod 307 and the water inlet 304 are on the same vertical plane and are arranged in a one-to-one correspondence. The cross-sectional area of ​​the bottom port of the water inlet 304 is smaller than the cross-sectional area of ​​the bottom port of the first sealing ring 309. When the movable sealing plate 303 floats to the bottom of the second sealing ring 310, the positioning rod 307 is inserted into the water inlet 304. The second magnet 308 and the first magnet 305 are attracted and fixed. The first sealing ring 309 covers the water inlet 304, thereby forming a sealed state to prevent water leakage from the sampling tube 301.

[0051] like Figure 2 As shown, the storage component 5 includes a storage tray 501, which limits the prefabricated water storage tank 201 to prevent it from rising, and also stores the sampling tube 301 after sampling. An inclined guide rail 502 is fixedly installed on the inner side of the storage tray 501. Figure 9 As shown, a conical base 503 is fixedly installed at one end of the inclined guide rail 502. A compression spring 504 is provided inside the conical base 503, and a corresponding cylinder 505 is provided at one end of the compression spring 504.

[0052] like Figure 9 As shown, the corresponding cylinder 505 and the conical base 503 are slidably connected. A cup-shaped rubber pad 506 is glued to the top of the corresponding cylinder 505. A support side plate 507 is fixedly installed on the top of the conical base 503. A positioning ring 508 is fixedly installed on the top of the support side plate 507.

[0053] The cross-sectional area of ​​the bottom port of the positioning ring 508 is larger than that of the bottom port of the sampling tube 301. The positioning ring 508 and the corresponding ring body 403 are set perpendicular to each other. With the setting of the cup-shaped rubber pad 506 and the positioning ring 508, when the sampling tube 301 falls and contacts the cup-shaped rubber pad 506, the positioning ring 508 limits the sampling tube 301, so that the sampling tube 301 remains vertical. At this time, the water in the underwater filter cartridge 102 will enter the sampling tube 301. When the water in the sampling tube 301 gradually increases, the sampling tube 301 will press down and push the cup-shaped rubber pad 506 to slide. When the movable sealing plate 303 floats up and keeps the sampling tube 301 sealed, the sampling tube 301 slides down and loses contact with the positioning ring 508, thus tilting onto the surface of the inclined guide rail 502. The inclined guide rail 502 guides the sampling tube 301, so that the sampling tube 301 rolls down onto the surface of the collection tray 501.

[0054] Regarding the above technical solution, it should be noted that when the present invention is actually used, when the sampling tube 301 falls onto the surface of the bowl-shaped rubber pad 506, the positioning ring 508 limits the sampling tube 301 to prevent it from falling. Water from the underwater filter cartridge 102 will flow into the sampling tube 301. The water enters the sampling tube 301 through the water inlet 304, and the rising water level in the sampling tube 301 causes the third buoyancy bag 306 to float, thereby driving the movable sealing plate 303 to float. When the movable sealing plate 303 floats to the bottom of the second sealing ring 310, the positioning rod 307 is inserted into the water inlet 304. Two magnets 308 are attracted and fixed to the first magnet 305. The first sealing ring 309 covers the water inlet 304. When the water in the sampling tube 301 is full, the weight of the sampling tube 301 increases. Under the influence of gravity, it will push the bowl-shaped rubber pad 506 down to squeeze the compression spring 504. At this time, the sampling tube 301 gradually loses contact with the positioning ring 508. As a result, the sampling tube 301 no longer maintains a vertical state after it is no longer limited. The sampling tube 301 tilts and falls onto the surface of the inclined guide rail 502. The inclined guide rail 502 guides the sampling tube 301, causing it to roll down to the collection tray 501.

[0055] Example 3: As Figure 7 As shown, the sealing assembly 4 includes a partition plate 401. The top of the partition plate 401 is set with an arc surface. A guide groove 402 is opened inside the partition plate 401. Due to the arc surface of the partition plate 401, when the water in the underwater filter cartridge 102 surges up, the partition plate 401 is used to make the water flow into the guide groove 402 and discharge it.

[0056] like Figure 10 As shown, a drain outlet is provided on the inner side of the upper float 101, and the guide channel 402 is connected to the drain outlet of the upper float 101. A corresponding ring 403 is fixedly installed at the center of the isolation plate 401.

[0057] A water passage groove 404 is provided on the outer side of the corresponding ring body 403. The guide groove 402 and the water passage groove 404 are arranged in a corresponding manner. When the sampling tube 301 slides down, the water in the underwater filter cartridge 102 surges up and flows through the water passage groove 404 into the guide groove 402, and then is discharged out of the float 101.

[0058] The partition plate 401 has a prefabricated slider 405 slidably connected inside. A tension spring 406 is fixedly connected to one side of the prefabricated slider 405, and a corresponding sealing block 407 is fixedly installed on one side of the prefabricated slider 405.

[0059] The number of corresponding sealing blocks 407 is set to multiple, and the multiple corresponding sealing blocks 407 are arranged in a ring at equal intervals about the vertical center line of the isolation plate 401. A rubber sealing gasket is bonded to the adjacent side of the multiple corresponding sealing blocks 407, and a third sealing ring 408 is bonded to the inner side of the corresponding ring body 403. The third sealing ring 408 is located at the top of the corresponding sealing blocks 407. Through the arrangement of the rubber sealing gasket and the third sealing ring 408, the multiple corresponding sealing blocks 407 form a sealed state when they are gathered together, preventing water in the underwater filter cartridge 102 from rushing into the upper float 101.

[0060] Regarding the above technical solution, it should be noted that when the present invention is actually used, when the sampling tube 301 falls from the toothed turntable 206, it will fall into the corresponding ring 403. The sampling tube 301 contacts the corresponding sealing block 407, thereby pushing the corresponding sealing block 407 to slide. Multiple corresponding sealing blocks 407 slide downwards, increasing the distance between them. At this time, the sampling tube 301 will slide out from the distance between the corresponding sealing blocks 407. During the sliding process, the force of the tension spring 406 causes the multiple corresponding sealing blocks 407 to press against the outer surface of the sampling tube 301. The resistance generated on the side slows down the descent speed of the sampling tube 301. After the sampling tube 301 loses contact with the corresponding sealing block 407, the tension spring 406 pushes the prefabricated slider 405 to slide, causing multiple corresponding sealing blocks 407 to gather together and form a seal with the third sealing ring 408, preventing water in the underwater filter cartridge 102 from rushing into the upper float 101. Through the setting of the water passage 404, when the water in the underwater filter cartridge 102 surges up during the descent of the sampling tube 301, it will flow into the guide channel 402 through the water passage 404 and then be discharged outside the upper float 101.

[0061] A water quality monitoring method based on multi-source data fusion includes the following steps:

[0062] S1: Open the cover 103, then insert the sampling component 3 into the toothed turntable 206, put the underwater filter 102 into the fishpond, and use the water flow to drive the first buoyancy bag 109 to float randomly on the water surface.

[0063] S2: When water enters the underwater filter cartridge 102, the water wets the micro sponge column 202. As the water content of the micro sponge column 202 increases, the water will form droplets and fall into the prefabricated water storage tank 201. The prefabricated water storage tank 201 gradually sinks and pulls the I-shaped roller 204 to rotate through the connecting rope 203, so that the gear 205 drives the toothed turntable 206 to rotate. When the sampling component 3 is aligned with the corresponding ring 403, the sampling component 3 will fall off.

[0064] S3: The sampling component 3 falls and pushes the corresponding sealing block 407 to slide. The sampling component 3 falls from the middle of the corresponding sealing block 407 to the bowl-shaped rubber pad 506. The water in the underwater filter cartridge 102 is injected into the sampling tube 301. The third buoyancy bag 306 floats up and drives the movable sealing plate 303 to float up. The positioning round rod 307 is inserted into the water inlet 304. The second magnet 308 is attracted and fixed to the first magnet 305. The first sealing ring 309 covers the water inlet 304 to form a seal.

[0065] S4: Under the influence of gravity, the sampling tube 301 pushes the bowl-shaped rubber pad 506 down and squeezes the compression spring 504. The sampling tube 301 gradually loses contact with the positioning ring 508, then tilts and falls onto the surface of the inclined guide rail 502, and finally rolls down to the storage tray 501.

[0066] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
