Description

Technical Field

[0001] This invention relates to the field of water quality monitoring technology, and in particular to a water pollutant monitoring device based on data analysis. Background Technology

[0002] There are many types of pollutants in water, which are generally classified into three categories according to their source and nature: physical, chemical, and biological. Water pollution seriously threatens my country's water resource security. Therefore, water quality monitoring is an important means of controlling water pollution. For example, Chinese patent CN222125231U discloses a water pollutant monitoring device. In order to improve the real-time monitoring of water pollutants, the monitoring device is directly placed on the surface of the water area to be measured. For example, Chinese patent CN216747690U discloses a lake pollutant monitoring device based on Beidou. However, in the process of water pollutant monitoring, the flow rate of water can easily affect the accuracy of the monitoring sensor, especially most electrode sensors. The high-speed water flow impacts the electrode membrane, which will generate a weak additional voltage. The pH and ORP readings will drift and fluctuate, thus affecting the accuracy of water pollutant monitoring. Summary of the Invention

[0003] The core of this invention lies in isolating a stable water quality monitoring buffer through a monitoring tube, stabilizing the flow state of the water, and solving the problem in the prior art where high-speed water flow affects the monitoring accuracy of the monitoring sensor.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A water pollutant monitoring device based on data analysis includes a floating platform floating on the water surface and a monitoring ball tube submerged in the water. The floating platform and the monitoring ball tube are fixedly connected by a connecting rod. A tube shaft is rotatably connected to the top of the monitoring ball tube, and a monitoring tube is fixedly connected to the bottom end of the tube shaft. A monitoring sensor module is fixedly connected to one end of the monitoring tube. The inner wall of the monitoring tube is provided with an arc-shaped groove, and the two ends of the monitoring tube are arranged in an arc shape corresponding to the arc-shaped groove. Both ends of the monitoring tube are in sliding contact with the arc-shaped groove. A water inlet is provided at the end of the monitoring tube away from the monitoring sensor module, and a water outlet is provided at the end of the monitoring tube close to the monitoring sensor module.

[0006] Furthermore, a filter screen is fixedly connected to one end of the monitoring tube, and a flow-directing tail fin is fixedly connected to the other end of the monitoring tube. The cross-section of the monitoring tube is streamlined.

[0007] Furthermore, the top of the tube shaft is rotatably connected to the floating platform, and a linkage gear is fixedly connected to the outside of the tube shaft. A drive motor is fixedly connected to one end of the top of the floating platform, and a drive gear is fixedly connected to the output end of the drive motor. The drive gear meshes with the linkage gear.

[0008] Optionally, the bottom end of the tube shaft is connected to the inside of the monitoring tube, and a suction chamber is fixedly connected to the middle of the tube shaft. A spiral impeller shaft is rotatably connected inside the suction chamber.

[0009] Furthermore, a water receiving tray is rotatably connected to the top of the tube shaft, the water receiving tray is fixedly connected to the floating platform, and a sampling motor is fixedly connected to the top of the water receiving tray. The output end of the sampling motor is fixedly connected to the top of the spiral impeller shaft.

[0010] Furthermore, a sampling port is provided at the bottom of the end of the water receiving tray away from the sampling motor, and a sampling bottle is threadedly connected to the bottom of the sampling port.

[0011] Furthermore, a discharge hole is provided at one end of the water receiving tray near the sampling bottle. The bottom of the discharge hole is flush with the top opening of the sampling port. A flip cover is rotatably connected to the top of the water receiving tray, and a sealing plug is fixedly connected to the bottom of the flip cover. The sealing plug is inserted into the mouth of the sampling bottle.

[0012] Preferably, an extension tube is fixedly connected to the connection between the tube shaft and the monitoring tube, and an expansion port is fixedly connected to the bottom end of the extension tube. Both ends of the expansion port are fixedly connected to a tension plate, which is made of elastic rubber material. The two tension plates close together by their own elasticity.

[0013] Furthermore, a connecting wire is fixedly connected to the end of the tension plate away from the expansion port. The two connecting wires pass through the water inlet and water outlet respectively. A buffer spring is fixedly connected to the end of the connecting wire away from the tension plate. The buffer spring is fixedly connected to the inner wall of the top of the monitoring ball tube. The two buffer springs are centrally symmetrical about the tube axis. The tensile deformation force of the buffer spring is greater than the bending deformation force of the tension plate.

[0014] Compared with the prior art, the advantages of this invention are: (1) The present invention drives the monitoring tube to rotate by the tube shaft, so that the two ends of the monitoring tube are respectively screwed into the arc groove, preventing the water flow from directly entering the monitoring tube and stabilizing the water sample inside the monitoring tube, thereby providing a relatively stable monitoring environment for the monitoring sensor module. When the water flow velocity in the water area to be tested is too fast, it effectively improves the pollutant monitoring accuracy of the monitoring sensor module. Furthermore, the water sample inside the monitoring tube is kept at a low flow rate through the inlet and outlet holes, effectively avoiding the water sample inside the monitoring tube from being completely still, which facilitates the monitoring sensor module to monitor water quality in real time.

[0015] (2) The present invention uses a sampling motor to drive a spiral impeller shaft to draw water samples from the monitoring tube into the suction chamber, and then sends the water samples to the receiving plate through the tube shaft. By directly discharging the initial water sample through the discharge hole, the inside of the receiving plate is flushed clean, and the water sample stagnating inside the tube shaft is drained and replaced. Then the sealing plug is removed, and the water sample continues to be discharged from the discharge hole. At the same time, the water sample enters the sampling bottle through the sampling port for collection, thereby effectively improving the purity of the collected water sample.

[0016] (3) The present invention drives the monitoring tube to rotate by the tube shaft, the position of the monitoring tube changes, the connecting wire is tightened, and the connecting wire moves in and out of the water inlet and outlet, so as to clear the water inlet and outlet. In addition, the two plates are pulled outward by the connecting wire and the water flow is guided into the expansion port by the plates, which makes it easier for the tube shaft to draw water samples. The tension deformation of the buffer spring is used to stretch and buffer the connecting wire, effectively preventing the connecting wire from being torn. Attached Figure Description

[0019] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0020] First implementation method: Please see Figures 1 to 3 A water pollutant monitoring device based on data analysis includes a floating platform 1 floating on the water surface and a monitoring cylinder 2 submerged in the water. The floating platform 1 and the monitoring cylinder 2 are fixedly connected by a connecting rod 101. A tube shaft 201 is rotatably connected to the top of the monitoring cylinder 2, and a monitoring tube 202 is fixedly connected to the bottom end of the tube shaft 201. A monitoring sensor module 203 is fixedly connected to one end of the monitoring tube 202. The data information obtained by the monitoring sensor module 203 is used for water pollutant analysis. A filter screen 207 is fixedly connected to one end of the monitoring cylinder 2. The filter screen 207 filters the water entering the monitoring cylinder 2 and prevents impurities in the water from entering the monitoring cylinder 2, thereby effectively avoiding affecting the monitoring accuracy of the monitoring sensor module 203. A flow-directing tail fin 208 is fixedly connected to the other end of the monitoring cylinder 2. The flow-directing tail fin 208 is used to make the monitoring cylinder 2 face the direction of water flow, so that the water flow can directly enter the monitoring cylinder 2. When setting up the monitoring device, the floating platform 1 and the monitoring tube 2 are placed in the water area to be measured. The floating platform 1 is tied with ropes to make it float on the water surface. The monitoring tube 2 is submerged directly below the floating platform 1. The water flow pushes the tube towards the tail fin 208, so that the monitoring tube 2 faces the direction of the water flow, allowing the water flow to directly enter the monitoring tube 2. The monitoring sensor module 203 inside the monitoring tube 202 is used to monitor pollutants in the water.

[0021] Please see Figures 3 to 6The inner wall of the monitoring tube 2 has an arc-shaped groove 204. Both ends of the monitoring tube 202 are arc-shaped and slide in contact with the arc-shaped groove 204. When the monitoring tube 202 rotates, both ends of the monitoring tube 202 screw into the arc-shaped groove 204, stabilizing the water sample inside the monitoring tube 202 and providing a relatively stable monitoring environment for the monitoring sensor module 203. A water inlet 205 is provided at the end of the monitoring tube 202 furthest from the monitoring sensor module 203, and a water outlet 206 is provided at the end of the monitoring tube 202 closest to the monitoring sensor module 203. Through the water inlet 205 and the water outlet 206, the water sample inside the monitoring tube 202 maintains a low flow rate, effectively preventing water from flowing into the monitoring tube 202. The sample is completely still, which facilitates the real-time monitoring of water quality by the monitoring sensor module 203. The cross-section of the monitoring tube 202 is streamlined, which facilitates the passage of external water flow and effectively reduces the impact of water flow on the monitoring tube 202. The top of the tube shaft 201 is rotatably connected to the floating platform 1, and a linkage gear 102 is fixedly connected to the outside of the tube shaft 201. A drive motor 103 is fixedly connected to one end of the top of the floating platform 1, and a drive gear 104 is fixedly connected to the output end of the drive motor 103. The drive gear 104 meshes with the linkage gear 102. The drive motor 103 realizes the rotational movement of the tube shaft 201 through the meshing of the drive gear 104 and the linkage gear 102, thereby realizing that both ends of the monitoring tube 202 are respectively screwed into the arc-shaped groove 204. When the water flow velocity in the water area to be tested is too fast, the drive motor 103 drives the tube shaft 201 to rotate through the meshing of the drive gear 104 and the linkage gear 102, so that both ends of the monitoring tube 202 are respectively screwed into the arc-shaped groove 204 (the monitoring tube 202 rotates 90 degrees), preventing water from directly entering the interior of the monitoring tube 202, stabilizing the water sample inside the monitoring tube 202, thereby providing a relatively stable monitoring environment for the monitoring sensor module 203, effectively improving the pollutant monitoring accuracy of the monitoring sensor module 203, and ensuring that the water sample inside the monitoring tube 202 remains at a low flow rate through the inlet hole 205 and the outlet hole 206, effectively preventing the water sample inside the monitoring tube 202 from becoming completely still, which facilitates the real-time monitoring of water quality by the monitoring sensor module 203.

[0022] Second implementation method: Compared to the first embodiment, the main additions are a suction chamber 3 and a spiral impeller shaft 301. The specific additions are as follows, while the remaining structures are the same as in the first embodiment.

[0023] Please see Figures 6 to 8The bottom end of the tube shaft 201 is connected to the interior of the monitoring tube 202. A suction chamber 3 is fixedly connected to the middle of the tube shaft 201. A spiral impeller shaft 301 is rotatably connected inside the suction chamber 3. A water receiving tray 302 is rotatably connected to the top end of the tube shaft 201. The water receiving tray 302 is fixedly connected to the floating platform 1, and a sampling motor 303 is fixedly connected to the top of the water receiving tray 302. The output end of the sampling motor 303 is fixedly connected to the top end of the spiral impeller shaft 301. The sampling motor 303 drives the spiral impeller shaft 301, causing the water sample in the monitoring tube 202 to be drawn into the suction chamber 3. Then, the water sample is sent to the water receiving tray 302 through the tube shaft 201. The bottom of the end of the water receiving tray 302 away from the sampling motor 303 is open. A sampling port 304 is provided, and a sampling bottle 305 is threadedly connected to the bottom of the sampling port 304. The water sample in the water receiving tray 302 enters the sampling bottle 305 through the sampling port 304 for collection. A discharge hole 306 is provided at one end of the water receiving tray 302 near the sampling bottle 305. The bottom of the discharge hole 306 is flush with the top opening of the sampling port 304. The water sample in the water receiving tray 302 is discharged through the discharge hole 306. A flip cover 307 is rotatably connected to the top of the water receiving tray 302. A sealing plug 308 is fixedly connected to the bottom of the flip cover 307. The sealing plug 308 is inserted into the bottle mouth of the sampling bottle 305. The sealing plug 308 blocks the sampling bottle 305, preventing the initially obtained water sample from entering the sampling bottle 305. When sampling is required in the water area to be tested, the sampling bottle 305 is installed at the bottom of the sampling port 304, and then the flip cover 307 is closed, so that the sealing plug 308 blocks the sampling bottle 305. The sampling motor 303 is started to drive the spiral impeller shaft 301, so that the water sample in the monitoring tube 202 is drawn into the suction chamber 3. Then, the water sample is sent to the water receiving tray 302 through the tube shaft 201. At this time, the sampling bottle 305 is in a blocked state, and the water sample that has just been obtained is directly discharged through the discharge hole 306 until the inside of the water receiving tray 302 is completely flushed clean and the water sample that has been stagnant inside the tube shaft 201 is drained and replaced. Then, the flip cover 307 is flipped open and the sealing plug 308 is removed. The water sample continues to be discharged from the discharge hole 306, and at the same time, the water sample enters the sampling bottle 305 through the sampling port 304 for collection, thereby effectively improving the purity of the water sample.

[0024] The third implementation method: Compared to the second embodiment, the main additions are a tension plate 402 and a connecting wire 403. The specific additions are as follows, while the remaining structures are the same as in the first embodiment.

[0025] Please see Figures 9 to 11An extension tube 4 is fixedly connected to the connection between the tube shaft 201 and the monitoring tube 202. An expansion port 401 is fixedly connected to the bottom end of the extension tube 4. A tension plate 402 is fixedly connected to both ends of the expansion port 401. The tension plates 402 are made of elastic rubber material. The two tension plates 402 close together due to their own elasticity. When the two tension plates 402 are closed, they effectively reduce the obstruction of the water flow, facilitating the water flow through the monitoring tube 202. When the two tension plates 402 are open, the water flow is guided by the tension plates 402 into the expansion port 401, facilitating the tube shaft 201 to draw water samples. A connecting wire 403 is fixedly connected to the external end of the tension plate 402 away from the expansion port 401. Two connecting wires 403 pass through the inlet hole 205 and the outlet hole 206 respectively, and a buffer spring 40 is fixedly connected to the end of the connecting wire 403 away from the tension plate 402. 4. The buffer spring 404 is fixedly connected to the top inner wall of the monitoring tube 2, and the two buffer springs 404 are centrally symmetrical about the tube axis 201. When the monitoring tube 202 rotates, the connecting wire 403 is tightened due to the change in the position of the monitoring tube 202. This allows the two opening plates 402 to be pulled outward by the connecting wire 403. At the same time, the connecting wire 403 moves in and out of the water inlet hole 205 and the water outlet hole 206 to unclog the water inlet hole 205 and the water outlet hole 206. The tensile deformation force of the buffer spring 404 is greater than the bending deformation force of the opening plate 402. The elasticity of the buffer spring 404 is used to buffer and protect the connecting wire 403, effectively preventing the connecting wire 403 from being torn. Moreover, the tensile deformation of the buffer spring 404 takes precedence over the bending deformation of the opening plate 402 after the bending deformation of the opening plate 402. The tube shaft 201 drives the monitoring tube 202 to rotate, so that both ends of the monitoring tube 202 are screwed into the arc-shaped groove 204 respectively (the monitoring tube 202 rotates 90 degrees). In case of excessive water flow velocity in the water area to be measured, the position of the monitoring tube 202 changes, the connecting wire 403 is tightened, and the two opening plates 402 are pulled outward by the connecting wire 403. The connecting wire 403 moves in and out of the water inlet hole 205 and the water outlet hole 206 to achieve the purpose of unblocking the water inlet hole 205 and the water outlet hole 206. The shaft 201 drives the monitoring tube 202 to rotate, causing the monitoring tube 202 to rotate 180 degrees. The positions of the two ends of the monitoring tube 202 are reversed, and the expansion port 401 faces the direction of water flow, guiding the water flow into the expansion port 401. The connecting wire 403 is also tightened, and the two opening plates 402 are pulled outward by the connecting wire 403 to open. The water flow is guided into the expansion port 401 by the opening plates 402, which facilitates the shaft 201 to draw water samples. At the same time, the connecting wire 403 is used for water intake. The movement of the water inlet and outlet holes 205 and 206 achieves the same purpose of unblocking the water inlet and outlet holes 205 and 206. Compared with the 90-degree rotation operation of the monitoring tube 202, the monitoring tube 202 rotates beyond 90 degrees (the monitoring tube 202 rotates 180 degrees, so that the two ends of the monitoring tube 202 are interchanged). The tensile deformation of the buffer spring 404 is used to stretch and buffer the connecting wire 403, effectively preventing the connecting wire 403 from being torn off.

[0026] The above description is merely a preferred embodiment of the present invention; it encompasses all the protection scope of the present invention.
