Description

Technical Field

[0001] This invention belongs to the field of sensor technology, and in particular relates to a water quality monitoring sensor. Background Technology

[0002] Water quality monitoring sensors are sensing devices based on electrochemical, optical, and biosensing detection principles. They can detect changes in physical parameters, chemical ions, organic matter, and pollutant concentrations in water bodies in real time and convert non-electrical water quality parameters into standard electrical or digital signals that can be collected and transmitted. They can be submerged for extended periods or installed online in aquatic environments for in-situ, continuous, and automatic monitoring of water quality parameters in surface water, sewage, tap water, and aquaculture water bodies.

[0003] When existing water quality monitoring sensors are in use, the presence of air bubbles in the water and the possibility of the water being in a flowing state can cause fluctuations in the detection data when air bubbles impact the sensor's detection head or when the water directly impacts the detection head, thus affecting the accuracy of the detection.

[0004] Therefore, it is necessary to invent a water quality monitoring sensor to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a water quality monitoring sensor to solve one of the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A water quality monitoring sensor, comprising: The sensor body has a data cable connected to its top. The detection head, installed at the bottom of the sensor body, is used to monitor water indicators. The protective device includes a protective plate, a filter plate, a conical plate, and a drive assembly. The protective plate and the filter plate are both semi-circular in design and are detachably connected together, forming a complete cylinder. The cylinder formed by the protective plate and the filter plate is rotatably fitted onto the bottom end of the sensor body. The conical plate is located at the bottom of the filter plate and is coaxial with the sensor body. The top of the conical plate is fixedly connected to the bottom of the protective plate. The drive assembly is installed on the top of the protective plate and the filter plate and is used to drive the protective plate and the filter plate to rotate around the sensor body when the water flows.

[0007] Furthermore, the drive assembly includes a fixed ring, a mounting ring, a fixed rod, and a fishtail plate. The fixed ring and the mounting ring are both rotatably sleeved on the sensor body near the bottom, and the mounting ring is located at the bottom of the fixed ring. The tops of the protective plate and the filter plate are fixedly connected to the bottom of the mounting ring. There are multiple fixed rods, which are evenly and vertically fixedly connected between the fixed ring and the mounting ring. The fishtail plate is fixedly connected to the side of the fixed ring, and the fishtail plate and the protective plate are in a directly opposite position.

[0008] Furthermore, a cleaning assembly is provided at the bottom of the detection head. The cleaning assembly includes a rotating shaft, cleaning rods, and a power mechanism. The rotating shaft is vertically rotatable and inserted through the center of the conical plate. There are multiple cleaning rods, which are evenly distributed in a ring at the top of the rotating shaft and are fixedly connected to the top of the rotating shaft. The cleaning rods are evenly provided with bristles on the side facing the detection head. The power mechanism is located at the bottom of the conical plate and is connected to the rotating shaft, used to drive the rotating shaft to rotate when the water flows.

[0009] Furthermore, the conical plate has multiple water inlet holes evenly distributed in a ring near the bottom, and the bottom end of the rotating shaft is fixedly connected to a conical sealing plate, which can fit against the bottom of the conical plate and seal the water inlet holes.

[0010] Furthermore, the power mechanism includes a spiral plate, a connecting ring, and connecting rods. There are multiple spiral plates, which are evenly distributed in a ring around the periphery of the protective plate and the filter plate. The connecting ring is inserted through the multiple spiral plates. There are multiple connecting rods, which are fixedly connected between the connecting ring and the sealing plate.

[0011] Furthermore, a limiting ring is fitted onto the rotating shaft. The limiting ring is located inside the conical plate. A screw conveyor blade is provided on the top of the limiting ring. The screw conveyor blade is evenly and fixedly connected to the rotating shaft. When the rotating shaft rotates, the screw conveyor blade can transport the water at the top of the conical plate downward through the water inlet.

[0012] Furthermore, a soft scraper is fixedly connected to the side of the spiral plate near the protective plate or filter plate, and the length of the soft scraper matches the length of the spiral plate.

[0013] Furthermore, the length of the cleaning rod matches the length of the detection head, and when the sealing plate is in contact with the bottom of the conical plate, the bristles on the cleaning rod are just able to adhere to the surface of the detection head.

[0014] Furthermore, the height of the spiral plate matches the height of the filter plate, and when the sealing plate is attached to the bottom of the conical plate, the soft scraper on the spiral plate can be attached to the protective plate or the filter plate.

[0015] The technical effects and advantages of this invention are as follows: 1. The present invention is equipped with a protective device. When the water is in a flowing state, as the water flow impacts the fish tail plate, the fish tail plate can drive the mounting ring to rotate through the fixing ring and fixing rod. As the mounting ring rotates, the protective plate can automatically move to the direction facing the water flow under the drive of the mounting ring, thereby protecting the detection head and preventing the water flow and air bubbles from directly impacting the detection head, thus ensuring the accuracy of the detection. 2. The present invention includes a cleaning component. As the sensor body enters the water body, the water flows from bottom to top and impacts the spiral plate. The spiral plate can drive the rotating shaft to rotate under the impact of the water flow. As the rotating shaft rotates, multiple cleaning rods can rotate around the detection head under the drive of the rotating shaft. The bristles on the cleaning rods clean the surface of the detection head, preventing impurities from adhering to the detection head and thus ensuring the accuracy of the detection. 3. This invention incorporates auger blades. When the water is in a flowing state, as the water impacts the spiral plate, the spiral plate can drive the shaft to rotate via the connecting rod. As the shaft rotates, the auger blades can transport the water in the inner area of ​​the protective plate downwards through the water inlet, while the water on the outer side of the protective plate can be filtered by the filter plate and enter the inner area of ​​the protective plate to contact the detection head. This ensures that the detection head can contact more water, thereby ensuring the accuracy of the detection results.

[0020] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This invention provides, for example Figures 1 to 5 The water quality monitoring sensor shown includes: a sensor body 1, a detection head 3, and a protective device. A data cable 2 is connected to the top of the sensor body 1. The detection head 3 is installed at the bottom of the sensor body 1 and is used to monitor water quality indicators. The protective device includes a protective plate 4, a filter plate 5, a conical plate 6, and a drive assembly. The protective plate 4 and the filter plate 5 are both semi-circular in design. The protective plate 4 and the filter plate 5 are detachably connected together and can be spliced ​​into a complete cylinder. The cylinder formed by the protective plate 4 and the filter plate 5 is rotatably fitted onto the bottom end of the sensor body 1. The conical plate 6 is located at the bottom of the filter plate 5 and is coaxial with the sensor body 1. The top of the conical plate 6 is fixedly connected to the bottom of the protective plate 4. The drive assembly is installed on the top of the protective plate 4 and the filter plate 5 and is used to drive the protective plate 4 and the filter plate 5 to rotate around the sensor body 1 when the water flows. The drive assembly includes a fixed ring 7, a mounting ring 8, a fixing rod 9, and a fishtail plate 10. The fixed ring 7 and the mounting ring 8 are both rotatably sleeved on the sensor body 1 near the bottom, and the mounting ring 8 is located at the bottom of the fixed ring 7. The tops of the protective plate 4 and the filter plate 5 are fixedly connected to the bottom of the mounting ring 8. There are multiple fixing rods 9, which are evenly and vertically fixedly connected between the fixed ring 7 and the mounting ring 8. The fishtail plate 10 is fixedly connected to the side of the fixed ring 7, and the fishtail plate 10 and the protective plate 4 are in a directly opposite position. During the process of the sensor body 1 being placed in the water, the conical plate 6 can always block the bottom of the detection head 3, thereby preventing debris in the water from hitting the detection head 3 and ensuring that the detection head 3 is not damaged. When the sensor body 1 reaches the specified depth, the water can enter the area where the detection head 3 is located after being filtered by the filter plate 5, thereby preventing impurities in the water from adhering to the surface of the detection head 3 and thus ensuring the accuracy of the detection. When the water is in a flowing state, as the water flow impacts the fishtail plate 10, the fishtail plate 10 can drive the mounting ring 8 to rotate through the fixing ring 7 and the fixing rod 9. As the mounting ring 8 rotates, the protective plate 4 can automatically move to face the direction of the water flow under the drive of the mounting ring 8, thereby protecting the detection head 3 and preventing the water flow and air bubbles from directly impacting the detection head 3, thus ensuring the accuracy of the detection.

[0021] like Figures 1 to 4 As shown, a cleaning assembly is provided at the bottom of the detection head 3. The cleaning assembly includes a rotating shaft 11, cleaning rods 12, and a power mechanism. The rotating shaft 11 is vertically rotatable and inserted through the axis of the conical plate 6. There are multiple cleaning rods 12, which are evenly distributed in a ring at the top of the rotating shaft 11 and are fixedly connected to the top of the rotating shaft 11. Brush bristles 13 are evenly arranged on the side of the cleaning rods 12 that faces the detection head 3. The power mechanism is located at the bottom of the conical plate 6 and is connected to the rotating shaft 11. It is used to drive the rotating shaft 11 to rotate when the water flows. The length of the cleaning rod 12 matches the length of the detection head 3, and when the sealing plate 15 is in contact with the bottom of the conical plate 6, the bristles 13 on the cleaning rod 12 can just be in contact with the surface of the detection head 3. The power mechanism includes a spiral plate 16, a connecting ring 17 and a connecting rod 18. There are multiple spiral plates 16, which are evenly distributed in a ring around the periphery of the protective plate 4 and the filter plate 5. The connecting ring 17 is inserted through and inserted between the multiple spiral plates 16. There are multiple connecting rods 18, which are fixedly connected between the connecting ring 17 and the sealing plate 15. As the sensor body 1 enters the water, the water flows upward and impacts the spiral plate 16. The spiral plate 16, under the resistance of the water flow, pulls the rotating shaft 11 upward, allowing multiple cleaning rods 12 to be distributed around the detection head 3. The bristles 13 on the cleaning rods 12 can keep in contact with the surface of the detection head 3. At the same time, as the water flows upward and impacts the spiral plate 16, the spiral plate 16 can drive the rotating shaft 11 to rotate. As the rotating shaft 11 rotates, the multiple cleaning rods 12 can rotate around the detection head 3 under the drive of the rotating shaft 11, thereby using the bristles 13 on the cleaning rods 12 to clean the surface of the detection head 3, preventing impurities from adhering to the detection head 3, and thus ensuring the accuracy of the detection. When the sensor body 1 reaches the specified depth, as the sensor body 1 stops moving, the rotating shaft 11 can drive the cleaning rod 12 to move downward under the action of gravity, so that the cleaning rod 12 can be separated from the detection head 3, thereby preventing the detection head 3 from being blocked by the cleaning rod 12. Furthermore, during the operation of the sensor body 1, when the water flow impacts the spiral plate 16, the spiral plate 16 can rotate under the impact of the water flow, thereby converting the impact force of the water on the sensor body 1 into the kinetic energy of the spiral plate 16 when it rotates, thus reducing the impact of the water flow on the sensor body 1 and ensuring the stability of the detection.

[0022] like Figure 3 and Figure 4 As shown, the conical plate 6 has multiple water inlet holes 14 evenly distributed in a ring near the bottom. The bottom end of the rotating shaft 11 is fixedly connected to a conical sealing plate 15, and the sealing plate 15 can fit against the bottom of the conical plate 6 and seal the water inlet holes 14. A limiting ring 19 is sleeved on the rotating shaft 11. The limiting ring 19 is located inside the conical plate 6. The top of the limiting ring 19 is provided with an auger blade 20. The auger blade 20 is evenly fixedly connected to the rotating shaft 11. When the rotating shaft 11 rotates, the auger blade 20 can transport the water at the top of the conical plate 6 downward through the water inlet holes 14. During the process of the sensor body 1 entering the water, as the sealing plate 15 comes into contact with the water, the sealing plate 15 can drive the rotating shaft 11 to move upward under the resistance of the water and fit together with the conical plate 6, thereby sealing the water inlet 14 and preventing impurities in the water from entering the inner area of ​​the protective plate 4 through the water inlet 14 during the process of the sensor body 1 entering the water. When the sensor body 1 reaches the specified depth, as the sensor body 1 stops moving, the sealing plate 15 can drive the rotating shaft 11 to move downward under the action of gravity, so that the sealing plate 15 can separate from the conical plate 6. At this time, the water inlet 14 is in the open state. When the water is in a flowing state, as the water impacts the spiral plate 16, the spiral plate 16 can drive the rotating shaft 11 to rotate through the connecting rod 18. As the rotating shaft 11 rotates, the auger blades 20 can transport the water in the inner area of ​​the protective plate 4 downward through the water inlet 14, while the water on the outer side of the protective plate 4 can enter the inner area of ​​the protective plate 4 after being filtered by the filter plate 5 and come into contact with the detection head 3, thereby ensuring that the detection head 3 can come into contact with more water, thus ensuring the accuracy of the detection results.

[0023] like Figure 5As shown, a soft scraper 21 is fixedly connected to the side of the spiral plate 16 near the protective plate 4 or the filter plate 5, and the length of the soft scraper 21 matches the length of the spiral plate 16, the height of the spiral plate 16 matches the height of the filter plate 5, and when the sealing plate 15 is in contact with the bottom of the conical plate 6, the soft scraper 21 on the spiral plate 16 can be in contact with the protective plate 4 or the filter plate 5. With the soft scraper 21 installed, as the sensor body 1 enters the water, the water flows upward and impacts the spiral plate 16. The spiral plate 16 can pull the rotating shaft 11 upward under the resistance of the water flow, so that the spiral plate 16 can be located in the area directly facing the filter plate 5. With the force of the water flow on the spiral plate 16, the spiral plate 16 can drive the rotating shaft 11 to rotate under the impact of the water flow. At the same time, the soft scraper 21 on the spiral plate 16 can scrape against the surface of the filter plate 5, thereby preventing impurities in the water from adhering to the side of the filter plate 5 and ensuring the filtration effect of the filter plate 5.
