Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring equipment, in particular to an online monitoring device for water quality at a pollution source. Background Art

[0002] Water pollution is caused by harmful chemicals that reduce or lose the use value of water. Water that pollutes the environment needs to be monitored using water quality monitoring devices. Online water quality monitoring devices are a system that uses sensors, the Internet of Things, and cloud platform technologies to collect, analyze, and issue early warnings on key water parameters in real time. They are widely used in environmental protection supervision, industrial production, tap water safety, and ecological protection. They are divided into pole-type monitoring stations, buoy-type monitoring systems, and micro-integrated monitoring stations.

[0003] Among them, the pollution source usually refers to the sewage discharge outlet. During monitoring, the water quality sensor is often placed directly into the water source to monitor whether the sewage discharge is qualified. However, the discharge water after sewage treatment may still have some impurities. The residual impurities may adhere to the water quality sensor, blocking the contact between the sensor and the water source, affecting the accuracy of monitoring. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an online monitoring device for water quality of a pollution source, comprising a monitoring pole and a connecting block, wherein a connecting cylinder is fixedly connected to the bottom of the connecting block;

[0005] A monitoring mechanism, wherein a suspension component is provided on the side wall of the monitoring mechanism, and a detection component is installed on the bottom of the suspension component, and the detection component is used to monitor the discharged sewage;

[0006] A scraping mechanism is installed on the inner wall of the detection component to remove impurities attached to the monitoring device;

[0007] A spraying mechanism, which is located on the inner wall of the detection component and is used to clean the scraping mechanism;

[0008] A fixing sleeve is fixedly connected to the inner wall of the connecting cylinder, a spring push plate is provided on the inner wall of the connecting cylinder, and a blocking plate is rotatably connected to the side wall of the spring push plate;

[0009] When it is necessary to monitor the discharged sewage, the detection component is placed in the sewage and the sewage is monitored through the detection component. When the sewage discharge volume increases, the scraping mechanism will be pushed to move to scrape off the impurities around the detection component, effectively preventing a large amount of impurities from adhering to the surface of the monitoring device, which will affect the direct contact between the monitoring device and the sewage, thereby ensuring the accuracy of the monitoring device.

[0010] Preferably, the monitoring agency includes:

[0011] A suspension component, the bottom of which is fixed to the top of the connecting block, and is used to suspend the monitoring mechanism;

[0012] A detection component, the top of which is fixedly arranged on the bottom of the connection block, and is used to monitor discharged sewage;

[0013] When monitoring discharged sewage, the suspended component is suspended above the sewage, allowing the detection component to penetrate into the sewage and monitor the sewage through monitoring equipment.

[0014] Preferably, the scraping mechanism comprises:

[0015] The pushing component is fixedly arranged on the inner wall of the connecting cylinder and is used to allow water flow to push the spring push plate to move;

[0016] The reset assembly is fixedly arranged on the side wall of the spring push plate and is used to return the spring push plate to its original position;

[0017] A reciprocating assembly is fixed to the inner wall of the connecting cylinder through a fixing member and is used for reciprocating movement to scrape away impurities;

[0018] The fixing member includes a fixing plate fixedly connected to the inner wall of the connecting tube, and a sliding rod is provided on the inner wall of the connecting tube;

[0019] Among them, when the discharge volume of sewage increases, the pushing component will be pushed to move. Through the reset component, the pushing component will move a certain distance and then return to its position. When the pushing component moves, the reciprocating component will reciprocate to scrape off impurities from the monitoring device, effectively preventing impurities from affecting the direct contact between the monitoring device and sewage, thereby ensuring the accuracy of monitoring by the monitoring device.

[0020] Preferably, the spraying mechanism comprises:

[0021] A blocking component is fixedly arranged on the inner wall of the connecting cylinder and is used to remove impurities on the surface of the reciprocating component;

[0022] The extrusion assembly is fixedly arranged on the top of the sliding rod and is used to squeeze the liquid out;

[0023] Among them, when the reciprocating component moves, the blocking component will block the reciprocating component and remove impurities on the surface of the reciprocating component. At the same time, the reciprocating component will drive the extrusion component to descend and spray liquid to flush the blocking component, ensuring the cleanliness of the reciprocating component and affecting the cleaning effect of the monitoring equipment.

[0024] Preferably, the suspension assembly includes four suspension frames fixedly connected to the outer wall of the connection block;

[0025] The detection component includes a fixed rod fixedly connected to the bottom of the connecting block, and the bottom of the fixed rod is fixedly connected to the water quality sensor;

[0026] When it is necessary to test the discharged sewage, the connecting block is placed in the sewage, and the connecting block is suspended on the sewage through the suspension frame. Then the connecting block is rotated so that the right side of the connecting tube is aligned with the flow direction of the sewage. After that, the connecting block is fixed to keep the connecting block in place, so that the water quality sensor is in contact with the sewage to monitor the sewage.

[0027] Preferably, the pushing assembly includes two push rods fixedly connected to the side wall of the fixing sleeve, and the outer wall of the spring push plate is slidably connected to the inner wall of the fixing sleeve;

[0028] Among them, since sewage discharge usually has peak and off-peak periods, when sewage discharge is at its peak, the flow rate of sewage will accelerate. When the flowing sewage enters the right side of the connecting tube, the sewage will push the blocking plate to move, driving the spring push plate to move, so that it accumulates rebound force.

[0029] Preferably, the reset assembly includes a connecting sleeve fixedly connected to the side wall of the spring push plate, a spring arc rod is slidably connected to the inner wall of the connecting sleeve, the side wall of the spring arc rod is fixedly connected to the side wall of the blocking plate, and a special-shaped groove is opened on the inner wall of the connecting sleeve;

[0030] Among them, as the baffle plate and the spring push plate continue to move, the baffle plate will contact the push rod. The baffle plate continues to move, and the push rod will push the baffle plate to rotate, pulling the spring arc rod to move, allowing the spring arc rod to accumulate rebound force. As the baffle plate rotates, the contact area between the baffle plate and the water flow will decrease, and the pushing force of the water flow on the baffle plate will decrease. At this time, the rebound force of the spring push plate will be released, allowing itself to return to its position, separating the baffle plate from the push rod, allowing the rebound force of the spring arc rod to be released, causing the baffle plate to return to its position, allowing the sewage to continue to push the baffle plate to move, and so on and so forth, allowing the spring push plate to move back and forth.

[0031] Preferably, the reciprocating assembly includes a connecting rod rotatably connected to the side wall of the spring push plate, the outer wall of the sliding rod is slidably connected to the inner wall of the fixed plate, and the inner wall of the connecting rod is rotatably connected to the outer wall of the sliding rod;

[0032] An annular scraper is provided on the inner wall of the connecting cylinder, and the top of the annular scraper is fixedly connected to the bottom of the sliding rod;

[0033] Among them, when the spring push plate moves toward the fixed rod, it will push the connecting rod to rotate, allowing the connecting rod to push the sliding rod down, and the sliding rod will drive the annular scraper to descend and contact the water quality sensor to scrape off impurities attached to the surface of the water quality sensor. When the spring push plate moves back and forth, it will drive the annular scraper to move up and down to continuously scrape off impurities attached to the surface of the water quality sensor. By utilizing the flow of water, the annular scraper can be moved up and down to scrape off impurities on the surface of the water quality sensor, effectively preventing a large amount of impurities from adhering to the surface of the water quality sensor, which will affect the direct contact between the water quality sensor and sewage, thereby ensuring the accuracy of water quality sensor monitoring.

[0034] Preferably, the blocking assembly comprises two spring arc blocks slidably connected to the inner wall of the fixed rod, a piston cylinder is fixedly connected to the outer wall of the fixed rod, and a piston ring is slidably connected to the inner wall of the piston cylinder;

[0035] Among them, when the discharged sewage is at a low peak period, the flow speed of the sewage slows down, the thrust on the baffle is weakened, and the rebound force of the spring push plate will be released, allowing itself to return to its position, driving the annular scraper to return. When the discharged sewage is at a peak again, the flow rate accelerates, pushing the spring push plate to move, causing the annular scraper to drop, and the impurities on the inclined surface of the annular scraper will contact the spring arc block. The annular scraper continues to move, and the spring arc block will scrape off the impurities on the inclined surface of the annular scraper, keeping the annular scraper clean. By removing impurities on the surface of the annular scraper, it can effectively prevent the annular scraper from continuously scraping impurities, causing more impurities to adhere to the surface of the annular scraper, affecting the cleaning effect of the annular scraper on the water quality sensor.

[0036] Preferably, the extrusion assembly includes a connecting rod fixedly connected to the top of the piston ring, the bottom of the connecting rod is fixedly connected to the top of the sliding rod, and ten injection holes are opened on the inner wall of the piston cylinder;

[0037] Among them, when the sliding rod descends, it will drive the connecting rod to descend, and the connecting rod will push the piston ring to descend, squeezing the sewage in the piston cylinder, and allowing the squeezed sewage to be ejected through the injection hole. Due to the small size of the injection hole, the sewage will produce a strong impact force, spraying towards the surface of the spring arc block, and dispersing the impurities attached to the surface of the spring arc block.

[0038] The present invention has the following beneficial effects:

[0039] (1) When the present invention is used, the connecting block is placed in the sewage, and the connecting block is suspended on the sewage through the suspension component. Then, the sewage is monitored through the detection component. When the flow speed of the sewage is accelerated, when the flowing sewage enters the right side of the connecting tube, the sewage will push the blocking plate to move, drive the spring push plate to move, push the connecting rod to rotate, push the sliding rod to drop, and let the annular scraper drop to scrape off the impurities attached to the surface of the water quality sensor. By utilizing the flow of water, the annular scraper scrapes off the impurities on the surface of the water quality sensor, effectively preventing a large amount of impurities from adhering to the surface of the water quality sensor, which will affect the direct contact between the water quality sensor and the sewage, thereby ensuring the accuracy of the water quality sensor monitoring.

[0040] (2) In the present invention, when the spring arc rod moves, sewage will enter the connecting sleeve through the special-shaped groove. When the blocking plate is separated from the top rod, the rebound force of the spring arc rod is released, driving the blocking plate to return. Since there is sewage inside the connecting sleeve, the spring arc rod will push the sewage out of the special-shaped groove when it returns. Since the special-shaped groove has a complex flow channel, it will slow down the flow speed of the sewage, thereby slowing down the movement speed of the spring arc rod and reducing the return speed of the blocking plate, effectively preventing the blocking plate from returning quickly. The rebound force of the spring push plate has not been fully released and will be compressed again, resulting in a shorter moving distance of the spring push plate, making the reciprocating distance of the annular scraper shorter, making it difficult to fully scrape off impurities on the surface of the water quality sensor.

[0041] (3) In the present invention, when the discharged sewage is at a low peak, the flow rate of the sewage slows down, and the rebound force of the spring push plate will be released, driving the annular scraper to return to its position. When the discharged sewage is at a peak again, the flow rate will accelerate, pushing the spring push plate to move, causing the annular scraper to descend. The impurities on the inclined surface of the annular scraper will contact the spring arc block. At the same time, the spring arc block will be squeezed, causing the spring arc block to reversely squeeze the annular scraper. The annular scraper continues to move, and the spring arc block will scrape off the impurities on the inclined surface of the annular scraper. By removing the impurities on the surface of the annular scraper, the annular scraper can be effectively prevented from continuously scraping off impurities, resulting in more impurities adhering to the surface of the annular scraper, affecting the cleaning effect of the annular scraper on the water quality sensor.

[0042] (4) In the present invention, when the sliding rod descends, it drives the connecting rod to descend, and the connecting rod pushes the piston ring to descend, squeezing the sewage in the piston cylinder and allowing the squeezed sewage to be ejected through the injection hole. Since the injection hole is small in size, the sewage will generate a strong impact force and be ejected toward the surface of the spring arc block, thereby dispersing the impurities attached to the surface of the spring arc block and separating the impurities from the spring arc block, effectively preventing a large amount of impurities from being attached to the surface of the spring arc block. When the spring arc block contacts the annular scraper again, the impurities will still adhere to the annular scraper, affecting the cleaning of the annular scraper.

[0056] For example 1, please refer to Figures 1-4 The present invention is an online monitoring device for water quality at a pollution source, comprising a monitoring pole 111 and a connecting block 112, wherein a connecting tube 121 is fixedly connected to the bottom of the connecting block 112;

[0057] Monitoring mechanism 1, a suspension component 11 is provided on the side wall of the monitoring mechanism 1, and a detection component 12 is installed on the bottom of the suspension component 11, and the detection component 12 is used to monitor the discharged sewage;

When the sewage discharge volume increases, the scraping mechanism 2 will be pushed to move to scrape off the impurities around the detection component 12, effectively preventing a large amount of impurities from adhering to the surface of the monitoring device, which will affect the direct contact between the monitoring device and the sewage, thereby ensuring the accuracy of the monitoring device.

[0065] When monitoring the discharged sewage, the suspension component 11 is suspended on the sewage, and the detection component 12 is allowed to penetrate into the sewage, and the sewage is monitored by the monitoring device.

[0066] The scraping mechanism 2 comprises:

[0067] The pushing component 21 is fixedly arranged on the inner wall of the connecting cylinder 121 and is used to allow the water flow to push the spring push plate 212 to move;

[0070] The fixing member includes a fixing plate 231 fixedly connected to the inner wall of the connecting tube 121, and a sliding rod 232 is provided on the inner wall of the connecting tube 121;

[0071] Among them, when the discharge volume of sewage increases, the pushing component 21 will be pushed to move, and the resetting component 22 will allow the pushing component 21 to move a certain distance and then return to its position. When the pushing component 21 moves, the reciprocating component 23 will reciprocate to scrape off impurities from the monitoring device, effectively preventing impurities from affecting the direct contact between the monitoring device and sewage, thereby ensuring the accuracy of monitoring by the monitoring device.

[0075] Among them, when the reciprocating component 23 moves, the blocking component 31 will block the reciprocating component 23 and remove impurities on the surface of the reciprocating component 23. At the same time, the reciprocating component 23 will drive the extrusion component 32 to descend and spray liquid to flush the blocking component 31, ensuring the cleanliness of the reciprocating component 23 and affecting the cleaning effect of the monitoring equipment.

[0076] For example 2, please refer to Figures 1-9 The present invention is an online monitoring device for water quality of a pollution source. Based on Example 1, the suspension assembly 11 includes four suspension frames 113 fixedly connected to the outer wall of the connection block 112;

[0077] The detection assembly 12 includes a fixing rod 122 fixedly connected to the bottom of the connecting block 112, and a water quality sensor 123 is fixedly connected to the bottom of the fixing rod 122;

[0078] When the discharged sewage needs to be tested, the connecting block 112 is placed in the sewage, and the connecting block 112 is suspended on the sewage through the suspension frame 113. Then, the connecting block 112 is rotated so that the right side of the connecting tube 121 is aligned with the flow direction of the sewage, such as: Figure 4 As shown in the state of G, the connecting block 112 is then fixed to keep the connecting block 112 in place, and the water quality sensor 123 is brought into contact with the sewage to monitor the sewage.

[0079] The pushing assembly 21 includes two push rods 214 fixedly connected to the side walls of the fixing sleeve 211, and the outer wall of the spring push plate 212 is slidably connected to the inner wall of the fixing sleeve 211;

[0080] Among them, since sewage discharge usually has peak and off-peak periods, when sewage discharge is at its peak, the flow speed of the sewage will accelerate. When the flowing sewage enters the right side of the connecting tube 121, the sewage will push the blocking plate 213 to move, driving the spring push plate 212 to move, so that it accumulates rebound force.

[0081] The reset assembly 22 includes a connecting sleeve 221 fixedly connected to the side wall of the spring push plate 212. A spring arc rod 222 is slidably connected to the inner wall of the connecting sleeve 221. The side wall of the spring arc rod 222 is fixedly connected to the side wall of the blocking plate 213. A special-shaped groove 223 is formed on the inner wall of the connecting sleeve 221.

[0082] The spring arc rod 222 is released, and the blocking plate 213 returns to its original position, so that the sewage continues to push the blocking plate 213 to move, and so on and so forth, so that the spring push plate 212 moves back and forth.

[0083] The reciprocating assembly 23 includes a connecting rod 233 rotatably connected to the side wall of the spring push plate 212, an outer wall of the sliding rod 232 is slidably connected to the inner wall of the fixed plate 231, and an inner wall of the connecting rod 233 is rotatably connected to the outer wall of the sliding rod 232;

[0084] An annular scraper 234 is provided on the inner wall of the connecting cylinder 121, and the top of the annular scraper 234 is fixedly connected to the bottom of the sliding rod 232;

[0085] Among them, when the spring push plate 212 moves toward the fixed rod 122, it will push the connecting rod 233 to rotate, so that the connecting rod 233 pushes the sliding rod 232 to descend, and the sliding rod 232 will drive the annular scraper 234 to descend and contact the water quality sensor 123, scraping off impurities attached to the surface of the water quality sensor 123. When the spring push plate 212 moves back and forth, it will drive the annular scraper 234 to move back and forth up and down, continuously scraping off impurities attached to the surface of the water quality sensor 123. By utilizing the flow of water, the annular scraper 234 moves back and forth up and down to scrape off impurities on the surface of the water quality sensor 123, effectively preventing a large amount of impurities from adhering to the surface of the water quality sensor 123, which will affect the direct contact between the water quality sensor 123 and the sewage, thereby ensuring the accuracy of monitoring by the water quality sensor 123.

[0086] The blocking assembly 31 includes two spring arc blocks 311 slidably connected to the inner wall of the fixed rod 122 , a piston cylinder 312 is fixedly connected to the outer wall of the fixed rod 122 , and a piston ring 313 is slidably connected to the inner wall of the piston cylinder 312 ;

[0087] Among them, when the discharged sewage is at a low peak period, the flow speed of the sewage slows down, the thrust on the blocking plate 213 is weakened, and the rebound force of the spring push plate 212 will be released, allowing itself to return to its position, driving the annular scraper 234 to return to its position. When the discharged sewage is at a peak again, the flow speed accelerates, pushing the spring push plate 212 to move, causing the annular scraper 234 to drop. The impurities on the inclined surface of the annular scraper 234 will contact the spring arc block 311, and the annular scraper 234 will continue to move. The spring arc block 311 will scrape off the impurities on the inclined surface of the annular scraper 234, keeping the annular scraper 234 clean. By removing impurities on the surface of the annular scraper 234, the annular scraper 234 can be effectively prevented from continuously scraping impurities, resulting in more impurities adhering to the surface of the annular scraper 234, affecting the cleaning effect of the annular scraper 234 on the water quality sensor 123.

[0088] The extrusion assembly 32 includes a connecting rod 321 fixedly connected to the top of the piston ring 313. The bottom of the connecting rod 321 is fixedly connected to the top of the sliding rod 232. Ten injection holes 322 are opened on the inner wall of the piston cylinder 312.

[0089] Among them, when the sliding rod 232 descends, it will drive the connecting rod 321 to descend, and the connecting rod 321 will push the piston ring 313 to descend, squeezing the sewage in the piston cylinder 312, and allowing the squeezed sewage to be ejected through the injection hole 322. Due to the small size of the injection hole, the sewage will generate a strong impact force, spraying towards the surface of the spring arc block 311, and dispersing impurities attached to the surface of the spring arc block 311.

[0090] There is no limit on the number of the above components, and relevant technicians in this field can freely set them according to actual needs, as long as the above components are installed in the corresponding component connection positions.

[0091] A specific application of this embodiment is as follows: when the present invention is used, the device is moved to the sewage outlet to be monitored, the connecting block 112 is placed in the sewage, and the connecting block 112 is suspended above the sewage by the suspension frame 113. Then, the connecting block 112 is rotated so that the right side of the connecting tube 121 is aligned with the flow direction of the sewage, such as: Figure 4As shown in the state of G in the middle, after that, the connecting block 112 is fixed, and the connecting block 112 is kept in place, so that the water quality sensor 123 is in contact with the sewage to monitor the sewage. Since sewage discharge usually has peak and low peak periods, when the sewage discharge is at the peak period, the flow rate of the sewage will accelerate. When the flowing sewage enters the right side of the connecting cylinder 121, the sewage will push the blocking plate 213 to move, driving the spring push plate 212 to move, so that it accumulates rebound force. As the blocking plate 213 and the spring push plate As the blocking plate 212 continues to move, the blocking plate 213 will contact the push rod 214. As the blocking plate 213 continues to move, the push rod 214 will push the blocking plate 213 to rotate, pulling the spring arc rod 222 to move, allowing the spring arc rod 222 to accumulate rebound force. As the blocking plate 213 rotates, the contact area between the blocking plate 213 and the water flow will decrease, and the driving force of the water flow on the blocking plate 213 will decrease. At this time, the rebound force of the spring push plate 212 will be released, allowing itself to return to its original position, so that the blocking plate 213 The spring push plate 212 is separated from the top rod 214, and the rebound force of the spring arc rod 222 is released, so that the blocking plate 213 returns to its original position, and the sewage continues to push the blocking plate 213 to move. This reciprocating movement allows the spring push plate 212 to move back and forth. When the spring push plate 212 moves toward the fixed rod 122, it pushes the connecting rod 233 to rotate, so that the connecting rod 233 pushes the sliding rod 232 to move down, and the sliding rod 232 drives the annular scraper 234 to move down and contact the water quality sensor 123, scraping off impurities attached to the surface of the water quality sensor 123. By utilizing the flow of water, the annular scraper 234 is reciprocated up and down to scrape off impurities attached to the surface of the water quality sensor 123, effectively preventing a large amount of impurities from being attached to the surface of the water quality sensor 123, which would affect the direct contact between the water quality sensor 123 and the sewage, thereby ensuring the accuracy of the water quality sensor 123 monitoring.

[0092] Secondly, when the blocking plate 213 contacts the top rod 214 and the blocking plate 213 rotates, driving the spring arc rod 222 to move, the sewage will enter the connecting sleeve 221 through the special-shaped groove 223. When the blocking plate 213 is separated from the top rod 214, the rebound force of the spring arc rod 222 will be released, driving the blocking plate 213 to return. Since there is sewage inside the connecting sleeve 221, the spring arc rod 222 will push the sewage out of the special-shaped groove 223 when it returns. Since the special-shaped groove 223 has a complex flow channel, it will slow down the flow rate of the sewage. The spring push plate 212 is compressed again before the spring push plate 212 is fully released, resulting in a shorter travel distance for the spring push plate 212 and a shorter reciprocating travel distance for the annular scraper 234, making it difficult to fully scrape off impurities on the surface of the water quality sensor 123.

[0093] Secondly, when the discharged sewage is at a low peak, the flow rate of the sewage slows down, the thrust on the blocking plate 213 is weakened, and the rebound force of the spring push plate 212 is released, allowing itself to return to its position, driving the annular scraper 234 to return to its position. When the discharged sewage is at a peak again, the flow rate is accelerated, pushing the spring push plate 212 to move, allowing the annular scraper 234 to descend, and the impurities on the inclined surface of the annular scraper 234 will contact the spring arc block 311. At the same time, the spring arc block 311 is squeezed and retracted into the fixed rod 122, so that it accumulates rebound force, allowing the spring arc block 311 squeezes the annular scraper 234, and the annular scraper 234 continues to move. The spring arc block 311 scrapes off impurities on the inclined surface of the annular scraper 234, keeping the annular scraper 234 clean. The spring arc block 311 retracts into the fixed rod 122, allowing the annular scraper 234 to move smoothly. By removing impurities on the surface of the annular scraper 234, it is effectively prevented that the annular scraper 234 continues to scrape impurities, resulting in more impurities adhering to the surface of the annular scraper 234, affecting the cleaning effect of the annular scraper 234 on the water quality sensor 123;

[0094] Secondly, when the sliding rod 232 descends, it will drive the connecting rod 321 to descend, and the connecting rod 321 will push the piston ring 313 to descend, squeezing the sewage in the piston cylinder 312, and allowing the squeezed sewage to be ejected through the injection hole 322. Due to the small size of the injection hole, the sewage will produce a strong impact force and spray against the surface of the spring arc block 311, dispersing the impurities attached to the surface of the spring arc block 311, separating the impurities from the spring arc block 311, and effectively preventing a large amount of impurities from adhering to the surface of the spring arc block 311. When the spring arc block 311 contacts the annular scraper 234 again, the impurities will still adhere to the annular scraper 234, affecting the cleaning of the annular scraper 234.
