Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water pollution monitoring, in particular to a water quality environment monitoring device based on Internet of Things. BACKGROUND

[0002] In the long-term online monitoring of water quality environment, the window or membrane surface of the detection probe will inevitably suffer from the attachment of pollutants, which mainly include algae, microbial membranes, inorganic salt scale, and suspended impurities such as waterweeds and fibers. The accumulation of pollutants will physically shield the sensor interface, hinder the exchange of substances, or cause optical scattering, directly leading to distorted monitoring data, signal drift, and even permanent damage to the sensor.

[0003] The existing device adopts a single rotating brush or blade. Such a single-dimensional motion trajectory is difficult to completely fit the complex curved surface of the detection probe, especially for the bottom, shoulder, or irregular protruding parts of the detection probe. It is easy to form a cleaning blind area. With the passage of time, the pollutants in the blind area continue to accumulate, eventually leading to local functional failure. In addition, the traditional mechanical cleaning only completes the stripping step, but lacks removal means. The pollutants brushed off are often suspended in the water around the detection probe and will reattach to the cleaned or uncleaned detection probe surface under the action of water flow, forming serious secondary pollution. This vicious cycle of brushing and reattaching greatly weakens the actual effect of cleaning and accelerates the pollution of the cleaning brush itself, leading to reduced cleaning effect on the detection probe and further greatly affecting the monitoring accuracy of the detection probe on water quality.

[0007] The bottom outer periphery of the triangular bracket is provided with an annular groove, and an annular rod is slidably connected in the annular groove, and the annular rod is fixedly installed on the inner side of the rotating ring.

[0008] As a preferred embodiment of the present invention, the rotating torsion assembly further includes a rotating base and a rotating arm. A base column is fixedly installed at the center of the inner bottom of the buoy seat, and the torsion ring moves around the outer periphery of the base column. Rotating bases are fixedly installed at both ends of the inner bottom of the buoy seat, and a drive shaft moves through the top of the rotating base. A rotating arm is fixedly installed at one end of the drive shaft near the base column. A support rod is fixedly installed on the side of the rotating arm near the base column. A support block is movably provided on the support rod. The bottom of the torsion ring is installed at the top of the cleaning ring through an arc-shaped rod.

[0009] The torsion ring has arc-shaped torsion plates fixedly installed at both ends, and the arc-shaped torsion plates are movably connected to the top of the support block through a rotating shaft. The servo motor is fixedly installed at the inner bottom of the buoy seat, and the drive shaft on one of the rotating bases is fixedly installed on the output end of the servo motor, while the drive shaft on the other rotating base is fixedly installed with a support rotating rod.

[0010] As a preferred technical scheme of the present application, the disturbance cleaning assembly further comprises a cleaning seat with a nozzle, the buoy seat is fixedly installed with a cleaning cylinder at the bottom of the end away from the servo motor, the support rotating rod is fixedly installed with a rotating disc at the end away from the twist ring, the rotating disc is movably arranged at the top center of the cleaning cylinder, the piston plate is movably arranged at the inner bottom of the cleaning cylinder, the top of the piston plate is fixedly installed with a piston rod, the top of the piston rod extends through to the inner top of the cleaning cylinder, the top end of the piston rod is movably connected with a connecting rod through a rotating shaft with the rotating disc, and the connecting rod is movably arranged at the inner top of the cleaning cylinder.

[0011] The bottom center of the cleaning cylinder is connected with a water outlet conduit, the water inlet conduit is fixedly installed at the bottom of the cleaning cylinder near one side of the cleaning ring, a filter hole is formed at the inlet of the water inlet conduit, the inner side of the cleaning ring is uniformly installed with a plurality of cleaning brushes made of rubber, and the cleaning seat is installed at the inner side of the cleaning ring at the positions of the two ends.

[0012] As a preferred technical scheme of the present application, the swing cleaning assembly comprises a first bevel gear fixedly installed on the support rotating rod, a connecting rotating rod movably connected at the bottom of the end of the buoy seat near the cleaning cylinder, a second bevel gear fixedly installed at the top end of the connecting rotating rod, the second bevel gear movably engaged with the first bevel gear, the bottom end of the connecting rotating rod fixedly installed on one of the arc-shaped protective plates, and the swing brush movably arranged at the inlet of the water inlet conduit.

[0013] Compared with the prior art, the present application has the following beneficial effects: 1、In the present application, the arc-shaped protective rod in the protection and stirring assembly swings from inside to outside to form a dynamic protection area for the detection probe, which can gently push away and guide away the winding objects, and fundamentally avoids the rigid collision and winding with the detection probe. The swing serves as a low-interference fluid disturbance source to generate a micro-flow field that spreads outward and actively takes away the fine particles attached to the surface of the detection probe, thereby creating a more representative water sample environment for subsequent detection, directly improving the accuracy of detection data. The swing of the arc-shaped protective plate and the arc-shaped protective rod disturbs the water flow, generating a self-cleaning effect, that is, the water flow generated by the stirring can naturally take away the finer suspended impurities from the surface of the detection probe, not only protecting the equipment, but also purifying the detection environment of the detection probe in advance, so that each water quality sampling is closer to the true state of the water body, greatly improving the reliability of long-term monitoring data.

[0014] 2. In this invention, the detection probe is protected by a protective actuation component, and a stable and reliable detection environment is created for the probe by removing entangled impurities such as aquatic plants around it, ensuring its long-term stable operation. The arc-shaped protective rod can effectively resist external collisions. At the same time, the unique actuation can actively remove entangled objects such as aquatic plants and fibers around the detection probe, ensuring the continuous normal operation of the detection probe, thereby ensuring the accuracy and continuity of the detection data. Through rotation or scraping action, aquatic plants and impurities attached to the detection probe are continuously removed and cleaned, effectively preventing entanglement and blockage, significantly improving the detection accuracy and equipment reliability in harsh environments, and extending the maintenance cycle.

[0015] 3. In this invention, the disturbance cleaning component can generate directional water flow to promptly wash away and remove various attachments that have fallen off the surface of the detection probe, effectively preventing secondary adsorption or deposition of impurities in the area surrounding the detection probe. The cleaning seat sprays disturbing water flow to quickly impact, engulf, and carry away the attachments such as biological slime and suspended particles washed off by the cleaning ring, ensuring that the stripped pollutants are effectively transported to an area far away from the detection probe.

[0016] 4. In this invention, the swing brush is driven to swing back and forth by the connecting rod in the swing cleaning assembly, performing a large-amplitude swing on the filter screen surface at the bottom of the water inlet pipe. Compared with rotary cleaning, this cleaning method can more effectively remove fibrous entanglement and accumulated impurities, significantly reducing the risk of clogging. It can powerfully remove fibrous material and attached impurities entangled on the filter screen, which is crucial for maintaining a stable water flow in the cleaning cylinder for a long time, making the water inside the cleaning cylinder cleaner, and thus making the impact cleaning of the cleaning brush and detection probe more thorough.

[0017] 5. In this invention, the rotating and twisting assembly drives the cleaning ring to move up and down and rotate, so that it performs a combined rotational and axial motion along the outer wall of the detection probe, thereby effectively brushing away the attached biological dirt or impurities, maintaining the cleanliness of the sensor interface. It can drive the cleaning ring to complete rotation and up and down twisting at the same time, forming a three-dimensional brushing, which can efficiently peel off the attached substances on the detection probe, and can brush and clean the impurities mixed in on the outer periphery of the detection probe without dead angles, greatly improving the detection accuracy of the detection probe.

[0018] 6. In this invention, the cleaning nozzle in the agitation cleaning assembly rotates and twists together with the cleaning brush. When the cleaning brush rubs the dirt off the surface of the detection probe, the cleaning nozzle located on the side immediately sprays water to accurately wash away the dirt. This ensures that the water flow can cover the entire surface of the detection probe without dead angles, preventing the pollutants brushed off from lingering around the detection probe or even re-adhering. This achieves highly efficient cleaning that peels off immediately. This is crucial for maintaining the long-term cleanliness of the detection probe and the accuracy of the detection data in complex waters rich in sticky pollutants or suspended particles.
