Description

Technical Field

[0001] This invention relates to the field of intelligent sensor technology, specifically to a water level monitoring device based on intelligent sensors. Background Technology

[0002] Capacitive water level sensors are widely used in hydrological monitoring, environmental early warning, and industrial liquid level measurement due to their advantages such as fast response, no mechanical wear, and easy integration with intelligent modules. However, in actual applications in open natural water bodies, their measurement accuracy and stability face severe challenges: continuous or random fluctuations caused by water flow, especially wind and waves, can directly lead to violent fluctuations in the local water surface where the sensor is located, causing the capacitive signal to jump at high frequencies, and the monitored data to deviate significantly from the true and gentle water level (such as tides and flood peaks) change trend. To cope with wave interference, existing technologies mainly adopt the following solutions: 1. Adding a simple static waveguide or opening a damping orifice to the outside of the sensor can help calm the local water flow. This method is effective for slow flow, but it will still cause significant fluctuations inside the sensor when subjected to continuous or large wave impacts. Furthermore, the fixed orifice diameter cannot adapt to changes in water flow intensity, resulting in limited filtration effect. 2. Constructing a large still water well and placing the sensor inside the well. Although this method can provide an extremely calm measurement environment, it has fatal drawbacks such as large engineering workload, high cost, fixed installation location, and inflexible deployment. 3. Thirdly, it relies on complex electronic filtering algorithms to process the sensor output signal. This post-processing method cannot eliminate the physical fluctuations of the sensor probe itself, and it is prone to serious lag or distortion under extreme fluctuations, while increasing the system power consumption and complexity. Summary of the Invention

[0003] The purpose of this invention is to provide a water level monitoring device based on an intelligent sensor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a water level monitoring device based on an intelligent sensor, comprising a monitoring cylinder, a filter screen fixed on the monitoring cylinder for filtering impurities, a sealing cover fixed to the upper end of the monitoring cylinder by bolts, and an air hole for balancing air pressure on the sealing cover, a handle fixed to the upper end of the sealing cover, and a capacitive water level sensor fixed to the lower end of the sealing cover, the capacitive water level sensor being disposed inside the monitoring cylinder; A drive mechanism is used to drive the monitoring cylinder to rotate using water flow or waves to achieve shock absorption and buffering. The drive mechanism is installed on the outside of the monitoring cylinder. A flow stabilizing mechanism is used to stabilize the water flow detected by the capacitive water level sensor. The flow stabilizing mechanism is installed inside the monitoring cylinder. A buffer mechanism is used to achieve secondary buffering and shock absorption of the monitoring cylinder, and the buffer mechanism is installed on the lower side of the monitoring cylinder; An adjustment mechanism is used to regulate the amount of water flowing into the monitoring cylinder, and the adjustment mechanism is installed on the outside of the monitoring cylinder.

[0005] Preferably, the driving mechanism includes a float plate slidably connected to the outside of the monitoring cylinder, and a fan plate is fixed on the float plate. The fan plates are symmetrically distributed vertically about the center line of the float plate. At the same time, protrusions are symmetrically fixed on the inner side of the float plate. The protrusions are slidably connected to the monitoring cylinder. Through the action of the float plate, the fan plate can be kept on the water surface. Through the impact of water flow or waves, the float plate can be rotated in conjunction with the fan plate. In conjunction with the action of the protrusions, the monitoring cylinder can be rotated synchronously. The rotation of the monitoring cylinder effectively reduces the vibration of the monitoring cylinder caused by the impact of water waves.

[0006] Preferably, the flow stabilizing mechanism includes a partition fixed inside the monitoring cylinder, with the partition located below the capacitive water level sensor. A guide pipe is fixed on the partition, and the guide pipe has evenly spaced connecting holes with a diameter of 2 mm. The height of the connecting holes is lower than the lower end face of the filter screen. Through the action of the connecting holes and the guide pipe, the water flow entering the upper part of the partition can be reduced, thereby preventing the water surface from floating and affecting the accuracy of the detection data of the capacitive water level sensor.

[0007] Preferably, a positioning ring is fixed on the flow guide pipe, and the positioning ring contacts the flow stabilizer plate to achieve positioning. The lower end face of the flow stabilizer plate is higher than the upper end face of the filter screen. At the same time, the flow stabilizer plate is slidably connected to the monitoring cylinder and the flow guide pipe. By moving the flow stabilizer plate, the distance between the flow stabilizer plate and the lower end face of the monitoring cylinder can be adjusted, thereby realizing the adjustment of the water storage space. This can reduce the excessive fluctuation of water flow at the detection position of the capacitive water level sensor caused by water wave impact.

[0008] Preferably, the flow stabilizing plate is fixed to one end of the first spring, and the other end of the first spring is fixed to the partition plate. The first springs are distributed at equal angles about the center of the flow stabilizing plate. The elastic action of the first spring can provide a basic guarantee for achieving the flow stabilizing effect.

[0009] Preferably, the buffer mechanism includes a base plate disposed on the lower side of the monitoring cylinder, with anchors evenly fixed on the lower end face of the base plate, and a sealing box fixed on the base plate. The sealing box and the movable plate are slidably connected, and a spring shock absorber is fixed between the movable plate and the sealing box. Through the action of the spring shock absorber, a basic guarantee can be provided for the realization of the secondary buffer of the monitoring cylinder, thereby effectively ensuring the stability of the monitoring cylinder.

[0010] Preferably, a baffle is fixed on the movable plate, and the baffle slides in contact with the sealing box, and the baffle seals the upper opening of the sealing box. At the same time, a turntable is connected to the upper baffle by a bearing, and the turntable is fixed to the monitoring cylinder. Through the action of the baffle, water and foreign objects can be prevented from entering the sealing box and causing corrosion damage to the spring shock absorber.

[0011] Preferably, the adjustment mechanism includes a crossbar that is slidably connected to the turntable, and a gravity ball is fixed at the end of the crossbar. The gravity ball is located on the outside of the turntable, and the rotation of the turntable and the centrifugal force of the gravity ball can provide a basic force for the movement of the crossbar.

[0012] Preferably, a bracket is also fixed on the crossbar, and a roller is connected to the bracket by a bearing. The roller is rotatably connected in the inclined groove, which is opened on a fixed plate. The fixed plate is symmetrically fixed on the outside of the movable ring, and the movable ring is slidably connected to the monitoring cylinder and the filter screen. When the crossbar moves, it drives the bracket and the roller to move. Through the rolling action between the roller and the inclined groove, the height of the fixed plate and the movable ring can be adjusted, so that the movable ring blocks some of the holes in the filter screen, reducing the water flow velocity entering the monitoring cylinder, and further realizing the buffering effect of water waves and water flow.

[0013] Preferably, a sliding rod is also fixed on the fixed plate, and the sliding rod is slidably connected to the movable block. A second spring is also fixed between the sliding rod and the movable block. At the same time, the movable block is slidably connected to the annular groove on the monitoring cylinder. Through the elastic action of the second spring, a basic force can be provided for the automatic reset of the fixed plate. Through the sliding guide action between the sliding rod and the movable block, the stability of the movement of the fixed plate and the movable ring can be ensured.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This water level monitoring device based on intelligent sensors, through a multi-stage buffer system consisting of a drive mechanism, an adjustment mechanism, a flow stabilization mechanism, and a buffer mechanism, can achieve vibration buffering and water level buffering under the impact of water flow and waves. The drive mechanism uses water flow energy to drive the monitoring cylinder to rotate, converting the positive impact force into rotational kinetic energy, achieving initial force relief and vibration reduction. The adjustment mechanism can automatically adjust the inlet surface of the filter screen according to the water flow intensity (i.e., the rotation speed of the turntable), dynamically optimizing the damping effect. The flow stabilization mechanism forms a variable volume water storage chamber through a spring-suspended flow stabilization plate, absorbing high-frequency water pressure pulsations. The buffer mechanism provides final displacement buffering for the entire monitoring cylinder through a spring shock absorber. Moreover, through a multi-stage collaborative mechanism, it can greatly suppress water flow fluctuations entering the measurement chamber from the physical source, creating a stable measurement environment for the capacitive sensor that far exceeds that of a static structure, ensuring the accuracy of the monitoring data. 2. This water level monitoring device based on intelligent sensors is driven by water flow or wave impact. The faster the water flow and the larger the waves, the faster the monitoring cylinder rotates, and the greater the centrifugal force generated by the gravity ball. This automatically pushes the moving ring upward, partially blocking the filter screen, reducing the inlet water flow area, and enhancing the damping effect. Conversely, in calm water, it maintains a larger opening to ensure water level tracking. Thus, it can achieve passive adaptive adjustment without external energy or control, enabling the device to intelligently match different hydrological conditions and always maintain the optimal filtering state to better meet actual use needs. 3. This water level monitoring device based on intelligent sensors, under the action of water waves and currents, can ensure the stability of the water flow entering the lower part of the monitoring cylinder through a buffer mechanism. Then, it enters the upper measuring chamber through a connecting hole with an extremely small diameter (e.g., 2mm). The small hole itself forms the final damping barrier. Combined with the inertial damping effect of the flow stabilizing plate, the water body reaching the area around the capacitive water level sensor is almost still. This can fundamentally eliminate the high-frequency noise of the capacitive signal, so that the output data directly reflects the real, slowly changing water level trend, greatly improving the accuracy, stability and reliability of the monitoring data.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-6 The present invention provides a technical solution: a water level monitoring device based on an intelligent sensor, including a monitoring cylinder 1, a filter screen 2 fixed on the monitoring cylinder 1 for filtering impurities, a sealing cover 3 fixed to the upper end of the monitoring cylinder 1 by bolts, and an air hole for balancing air pressure opened on the sealing cover 3, a handle 4 fixed to the upper end of the sealing cover 3, and a capacitive water level sensor 5 fixed to the lower end of the sealing cover 3, the capacitive water level sensor 5 being installed inside the monitoring cylinder 1. Drive mechanism 6 uses water flow or waves to drive the monitoring cylinder 1 to rotate in order to achieve shock absorption and buffering. Drive mechanism 6 is installed on the outside of monitoring cylinder 1. The flow stabilizing mechanism 7 is used to stabilize the water flow detected by the capacitive water level sensor 5. The flow stabilizing mechanism 7 is installed inside the monitoring cylinder 1. The buffer mechanism 8 is used to achieve secondary buffering and shock absorption of the monitoring cylinder 1. The buffer mechanism 8 is installed on the lower side of the monitoring cylinder 1. The regulating mechanism 9 is used to regulate the amount of water flowing into the monitoring cylinder 1. The regulating mechanism 9 is installed on the outside of the monitoring cylinder 1.

[0019] The flow stabilizing mechanism 7 includes a partition 701 fixed inside the monitoring cylinder 1, located below the capacitive water level sensor 5. A guide pipe 702 is fixed on the partition 701, and the guide pipe 702 has evenly spaced connecting holes 703 with a diameter of 2mm. The height of the connecting holes 703 is lower than the lower end face of the filter screen 2. A positioning ring 704 is fixed on the guide pipe 702, and the positioning ring 704 contacts the flow stabilizing plate 705 for positioning. The lower end face of the flow stabilizing plate 705 is higher than the upper end face of the filter screen 2. The flow stabilizing plate 705 is slidably connected to the monitoring cylinder 1 and the guide pipe 702. The flow stabilizing plate 705 is fixed to one end of a first spring 706, and the other end of the first spring 706 is fixed to the partition 701. The first spring 706 is evenly distributed about the center of the flow stabilizing plate 705. When using this smart sensor-based water level monitoring device, such as Figures 1-6As shown, firstly, the anchor nails 802 are inserted into the bottom mud until the bottom plate 801 contacts the bottom mud. The stability of the entire device can be ensured by the action of multiple anchor nails 802. The height of the sealing cover 3 is higher than the water surface to prevent water from entering the monitoring cylinder 1 through the air hole on the sealing cover 3. After installation, the water enters the space formed by the monitoring cylinder 1 and the flow stabilizing plate 705 after the impurities are filtered by the filter screen 2. It then enters the detection chamber above the partition 701 through the connecting hole 703 and the guide pipe 702. Finally, the water level can be monitored by the capacitive water level sensor 5. The drive mechanism 6 includes a float plate 601 slidably connected to the outside of the monitoring cylinder 1, and a fan plate 602 is fixed on the float plate 601. The fan plates 602 are symmetrically distributed about the center line of the float plate 601. Simultaneously, protrusions 603 are symmetrically fixed to the inner side of the float plate 601, and the protrusions 603 are slidably connected to the monitoring cylinder 1. The buffer mechanism 8 includes a base plate 801 disposed on the lower side of the monitoring cylinder 1, and anchor bolts 802 are evenly fixed to the lower end face of the base plate 801. A sealing box 803 is fixed on the upper part of the monitoring cylinder 1. The sealing box 803 is slidably connected to the movable plate 804. A spring shock absorber 805 is fixed between the movable plate 804 and the sealing box 803. A baffle 806 is fixed on the movable plate 804. The baffle 806 contacts the sealing box 803 and slides. The baffle 806 seals the upper opening of the sealing box 803. A turntable 807 is connected to the upper baffle 806 by a bearing. The turntable 807 is fixed to the monitoring cylinder 1. After the device is installed, such as Figures 1-6 As shown, the float 601 floats on the water surface due to its own buoyancy. At this time, the lower fan plate 602 of the float 601 is below the water surface, and the upper fan plate 602 is above the water surface. During operation, when the water flow velocity increases or waves are present, the fan plate 602 and the float 601 rotate under the force of the water flow or waves. Combined with the action of the protrusion 603, this synchronously drives the monitoring cylinder 1 and the turntable 807 to rotate. The rotation of the monitoring cylinder 1... This device can effectively reduce the impact of water flow and waves on the monitoring cylinder 1, thereby reducing the vibration of the monitoring cylinder 1 under the action of water flow and waves. When the monitoring cylinder 1 cannot achieve complete buffering due to rotation, the force will have a certain impact on the monitoring cylinder 1, causing the monitoring cylinder 1 to move, thereby synchronously driving the turntable 807, baffle 806 and movable plate 804 to move. With the buffering effect of the spring shock absorber 805, the monitoring cylinder 1 can achieve secondary buffering and shock absorption, thereby ensuring the stability of the monitoring cylinder 1. The adjusting mechanism 9 includes a crossbar 901 slidably connected to the turntable 807, with a gravity ball 902 fixed at the end of the crossbar 901 and the gravity ball 902 located on the outside of the turntable 807; a bracket 903 is also fixed on the crossbar 901, and a roller 904 is connected to the bracket 903 by a bearing, and the roller 904 is slidably connected in the inclined groove 905, while the inclined groove 905 is opened on the fixed plate 906, the fixed plate 906 is symmetrically fixed on the outside of the movable ring 907, and the movable ring 907 is slidably connected to the monitoring cylinder 1 and the filter screen 2; a slide rod 908 is also fixed on the fixed plate 906, and the slide rod 908 is slidably connected to the movable block 909, and a second spring 910 is also fixed between the slide rod 908 and the movable block 909, while the movable block 909 is slidably connected to the annular groove on the monitoring cylinder 1; During the use of the device, such as Figures 1-6 As shown, when the monitoring cylinder 1, filter screen 2, and turntable 807 rotate due to water flow or waves, the rotation of the monitoring cylinder 1 and filter screen 2 reduces the impact of the water flow on the lower space inside the monitoring cylinder 1, achieving a buffering effect. The rotation of the turntable 807 synchronously drives the crossbar 901, gravity ball 902, movable ring 907, and movable block 909 to rotate. Combined with the sliding action between the movable block 909 and the annular groove on the monitoring cylinder 1, the stability of the movable ring 907's rotation is ensured. During the rotation of the gravity ball 902, when the centrifugal force generated by the rotation of the gravity ball 902 is greater than the elastic force of the second spring 910, the centrifugal force of the gravity ball 902 can... The crossbar 901 slides outwards toward the turntable 807, thereby driving the bracket 903 and roller 904 to move. In conjunction with the rolling action between the roller 904 and the inclined groove 905, the fixed plate 906 and the movable ring 907 can be moved upwards under force. In conjunction with the sliding guide action between the slide bar 908 and the movable block 909, the stability of the movement of the fixed plate 906 and the movable ring 907 can be ensured. When the movable ring 907 moves upwards, it can block the upper part of the mesh of the filter screen 2. By reducing the flow area of ​​water entering the monitoring cylinder 1, the fluctuation of the water surface at the lower side of the monitoring cylinder 1 caused by water flow and waves is reduced, thereby realizing the secondary buffering effect of water flow and effectively ensuring the stability of the water level in the monitoring cylinder 1. Furthermore, when the water surface under the monitoring cylinder 1 fluctuates due to water flow or waves, the fluctuation will impact the flow stabilizing plate 705. Combined with the sliding guiding action between the flow stabilizing plate 705, the monitoring cylinder 1, and the guide pipe 702, and the elastic action of the first spring 706, the flow stabilizing plate 705 can move within the monitoring cylinder 1, thereby automatically adjusting the distance between the flow stabilizing plate 705 and the bottom surface of the monitoring cylinder 1, and thus adjusting the size of the water storage cavity. This achieves a three-stage buffering effect on the water surface within the monitoring cylinder 1, ensuring the stability of the water surface. Moreover, due to the small diameter of the connecting hole 703, multi-stage buffering of the water surface within the monitoring cylinder 1 effectively ensures the smooth flow of water entering the partition 701 through the connecting hole 703 and the guide pipe 702, thereby ensuring the stability of the water level detected by the capacitive water level sensor 5. This effectively reduces the impact of water level fluctuations caused by water flow or waves on the normal operation of the capacitive water level sensor 5, better meeting actual usage requirements. In summary, during the use of the device, such as Figures 1-6 As shown, when water flow or waves are present, the force of the water flow or waves, combined with the action of the fan plate 602, causes the monitoring cylinder 1 and the turntable 807 to rotate, achieving a primary buffer against the water flow or waves. Combined with the secondary buffering and damping effect of the spring shock absorber 805, the overall stability of the device is ensured, preventing vibration caused by the impact of water flow or waves. Furthermore, under the action of water flow or waves, the rotation of the turntable 807 drives the gravity ball 902 to rotate. The centrifugal force generated by the rotation of the gravity ball 902 can further dampen the water flow. The height of the moving ring 907 is adjusted to partially block the mesh holes of the filter screen 2. Combined with the rotation of the device, this effectively reduces the impact of water flow and waves on the water body below the monitoring cylinder 1. Furthermore, the elasticity of the flow stabilizer 705 and the first spring 706 allows for spatial adjustment, making the water body below the monitoring cylinder 1 more stable. Finally, the damping effect of the small hole in the connecting hole 703 ensures that the water body around the capacitive water level sensor 5 is almost still, thus effectively ensuring the accuracy of the monitoring data.
