Description

Technical Field

[0001] This utility model relates to the technical field of water quality monitoring equipment, specifically to an intelligent monitoring device for water quality inspection. Background Technology

[0002] In water quality monitoring, sensors need to filter suspended impurities (such as silt, algae, and pollutant particles) from the water through a filter screen to prevent sensor probe clogging or contamination. Existing intelligent monitoring devices for water quality testing suffer from the following key technical deficiencies, which restrict monitoring reliability:

[0003] Filter screens are prone to accumulating dirt and are difficult to clean: Traditional devices have fixed filter screens, and sticky impurities in the water (such as algae and humus) easily adhere to the surface of the filter screen, clogging the filter holes, causing the sensor to be unable to contact the water and resulting in distorted monitoring data; without an active vibration anti-fouling structure, regular manual cleaning is required, resulting in high maintenance costs; some devices with vibration functions only vibrate in one direction, making it difficult for dirt to be removed. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent monitoring device for water quality inspection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent monitoring device for water quality inspection, comprising a buoy, a sensor fixedly connected to the lower center of the buoy plate, a connecting shell fixedly connected to the lower side of the buoy, four sets of first rotating blocks fixedly connected inside the connecting shell, a first rotating ring rotatably connected to the outer side of each first rotating block, a first spring fixedly connected to one side of each first rotating ring, a second rotating ring fixedly connected to the other end of each first spring, a second rotating block rotatably connected to one side of each second rotating ring, a filter cylinder fixedly connected between the four sets of second rotating blocks, the filter cylinder being sleeved on the outside of the sensor, an isolation frame fixedly connected to the upper outer side of the connecting shell, four sets of first motors fixedly connected to the inner side of the isolation frame, a rotating shaft fixedly connected to the power end of each first motor penetrating the isolation frame, the lower part of the rotating shaft rotatably connected to the lower interior of the connecting shell, outer rotating rods fixedly connected to both sides of the rotating shaft, an inner rotating rod slidably connected inside the outer rotating rod, and a rubber head fixedly connected to the other end of the inner rotating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses the rubber head to strike the filter screen cylinder in combination with multi-directional back-and-forth swinging to intensify the vibration effect. Suspended impurities and sticky stains in the water are difficult to adhere to the filter screen surface, reducing the filter pore clogging rate and eliminating the need for frequent manual cleaning, thus reducing maintenance costs.

[0013] 2. This utility model uses a second spring to push the inner rotating rod to extend and retract, so that even if the device shakes due to water fluctuations, the rubber head can always keep in contact with the filter screen cylinder, achieving a high impact coverage rate and avoiding the defects of contact failure in traditional devices;

[0014] 3. This utility model also uses a second motor to drive the rubber ring to slide up and down, which can actively remove stubborn sticky stains from the surface of the filter screen, further improving the anti-fouling effect, ensuring that the sensor is always in contact with the water, reducing monitoring data errors and significantly improving accuracy.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an intelligent monitoring device for water quality inspection, including a buoy 1, a sensor 2 fixedly connected to the lower center of the buoy 1 by bolts, a connecting shell 3 fixedly connected to the lower edge of the buoy 1 by welding, four sets of first rotating blocks 4 evenly distributed around the circumference of the connecting shell 3 and fixedly connected by welding, a first rotating ring 5 rotatably connected to the outer side of the first rotating blocks 4 by deep groove ball bearings, a first spring 6 fixedly connected to one side of the first rotating ring 5 by spot welding, a second rotating ring 7 fixedly connected to the other end of the first spring 6 by spot welding, four sets of second rotating blocks 8 rotatably connected to the inner side of the second rotating ring 7 by deep groove ball bearings, a filter screen cylinder 9 fixedly connected between the four sets of second rotating blocks 8 by welding, and the filter screen cylinder 9 being sleeved on the sensor. 2. On the outside, the filter cylinder 9 is used to filter water impurities and protect the sensor 2. The upper part of the outer side of the connecting shell 3 is fixedly connected to the isolation frame 12 by welding. Four sets of first motors 13 are evenly distributed along the circumference of the inner side of the isolation frame 12 and fixedly connected by bolts. The power end of the first motor 13 penetrates the isolation frame 12 and is fixedly connected to the rotating shaft 14 by a coupling. The lower part of the rotating shaft 14 is rotatably connected to the lower side of the connecting shell 3 by a deep groove ball bearing. The two sides of the rotating shaft 14 are fixedly connected to the outer rotating rod 15 by welding. The inner rotating rod 16 is slidably connected along the length direction of the outer rotating rod 15 by clearance fit. The end of the inner rotating rod 16 away from the outer rotating rod 15 is fixedly connected to the rubber head 17 by adhesive. The rubber head 17 is used to strike the filter cylinder 9 to avoid damaging the filter.

[0023] The first rotating ring 5 is fixedly connected to the inner support cylinder 10 by welding on the side close to the second rotating ring 7. The inner support cylinder 10 is slidably connected to the sliding cylinder 11 by clearance fit. The other end of the sliding cylinder 11 is fixedly connected to the side of the second rotating ring 7 by welding. The inner support cylinder 10 and the sliding cylinder 11 are sleeved inside the first spring 6 to provide axial guidance for the first spring 6, prevent the first spring 6 from radially shifting when it extends and retracts, and ensure the stable back-and-forth swing of the filter cylinder 9.

[0024] The inner rotating rod 16 is located inside the outer rotating rod 15 and is fixedly connected to a connecting piece 18 by welding. The connecting piece 18 and the inner wall of the outer rotating rod 15 are fixedly connected to a second spring 19 by spot welding. The second spring 19 is sleeved on the outside of the inner rotating rod 16 and pushes the inner rotating rod 16 outward under normal conditions to ensure that the rubber head 17 always fits the filter screen cylinder 9 and can still effectively strike when the water fluctuates.

[0025] A baffle plate 20 is fixedly connected to the upper outer side of the filter screen cylinder 9 by welding. The upper surface of the baffle plate 20 is tightly attached to the lower part of the connecting shell 3 to form a sealed isolation, preventing impurities in the water from entering the first spring 6 and other core components, and avoiding jamming and corrosion.

[0026] A connecting box 21 is fixedly connected to the lower outer side of the filter cylinder 9 by welding. A second motor 22 is fixedly connected to one side of the connecting box 21 by bolts. The power end of the second motor 22 penetrates the connecting box 21 and is fixedly connected to a threaded rod 24 by a coupling. The upper part of the threaded rod 24 is rotatably connected to the lower side of the baffle plate 20 by a deep groove ball bearing. A one-sided lug 26 is threadedly connected to the outer side of the threaded rod 24. A guide rod 25 is fixedly connected to the connecting box 21 by welding on the other side of the baffle plate 20. The guide rod 25 is parallel to the threaded rod 24. Another set of lugs 26 is slidably connected to the guide rod 25 by clearance fit. An installation ring 27 is fixedly connected to the two sets of lugs 26 by welding. A rubber ring 28 is fixedly connected to the inner side of the installation ring 27 by adhesive. The rubber ring 28 is tightly attached to the outer wall of the filter cylinder 9 and can scrape off stubborn stains on the surface when moving up and down.

[0027] Two sets of shielding frames 23 are fixedly connected to the upper two sides of the connecting box 21 and the shielding plate 20 by welding. The shielding frames 23 are sleeved on the outside of the threaded rod 24 and the guide rod 25 to prevent impurities from adhering to the surface of the threaded rod 24 and the guide rod 25 and to prevent the lug 26 from sliding and getting stuck.

[0028] Working principle: When this utility model is in use: the device is placed in the target water body for monitoring. The buoy 1 floats on the water surface, the filter cylinder 9 and the sensor 2 are immersed in the water body, and the shield 20 and the shield frame 23 isolate water impurities to prevent them from intruding into the core components.

[0029] The four sets of first motors 13 are started. The power end of the first motor 13 drives the rotating shaft 14 to rotate, which in turn drives the outer rotating rod 15, the inner rotating rod 16 and the rubber head 17 to make circular motion. The rubber head 17 periodically hits the filter screen cylinder 9. After the filter screen cylinder 9 is impacted, it compresses or stretches the first spring 6 through the second rotating block 8 and the second rotating ring 7. At the same time, the first rotating ring 5 rotates around the first rotating block 4, realizing the multi-directional back-and-forth swing of the filter screen cylinder 9, which intensifies the vibration. During the vibration, the second spring 19 pushes the inner rotating rod 16 to extend and retract, ensuring that the rubber head 17 always fits the filter screen cylinder 9. Even if the water fluctuates, the impact effect is not weakened. The suspended impurities on the surface of the filter screen cylinder 9 fall off under the action of vibration, avoiding adhesion and blockage.

[0030] When stubborn stains appear on the surface of the filter cylinder 9, the second motor 22 is started. The power end of the second motor 22 drives the threaded rod 24 to rotate. The threaded rod 24 drives one side lug 26 to move up and down along the threaded rod 24, while the other side lug 26 slides synchronously along the guide rod 25, which drives the mounting ring 27 and the rubber ring 28 to move up and down. The rubber ring 28 slides tightly against the outer wall of the filter cylinder 9, scraping off the stubborn stains on the surface. The stains are washed away with the water flow and do not require manual cleaning.

[0031] Sensor 2 collects water quality data in real time and transmits it to the backend via a wireless module.
