Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically to a protective cover for a water quality probe that is anti-collision and anti-entanglement. Background Technology

[0002] Water quality testing probes, as core equipment for collecting water parameters, are widely used in natural water bodies and industrial wastewater monitoring scenarios. Their operating environment is often accompanied by a large amount of impurities such as aquatic plants, algae, dead branches, and fishing net fragments. To protect the probes from impact damage, existing protective devices are mostly metal mesh covers or integrated plastic shells. While these structures can resist the impact of rocks and riverbeds to a certain extent, they lack the ability to protect against long, thin impurities floating in the water.

[0003] When existing equipment is in use, weeds and other impurities can become entangled in the sensor area of ​​the probe, obstructing the optical detection window and clogging the probe, thus affecting data accuracy. On the other hand, the entangled material can easily cause the connection between the probe and the mounting rod to loosen, or even cause the probe to fall into the water. Cleaning the entangled material requires frequent shutdowns and equipment retrieval, resulting in high equipment maintenance costs. This not only interrupts the monitoring process but also increases the safety risks for personnel working near water and the cost of equipment maintenance. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1 to 6This utility model provides a technical solution: a water quality probe protective cover that is anti-collision and anti-entanglement, including a column 1, an adjustment mechanism 2 at the upper end of the column 1, a protective shell 3 that cooperates with the adjustment mechanism 2 on one side of the column 1, an annular groove 4 on the outer side of the protective shell 3, a drive ring 5 rotatably fitted on the inner wall of the annular groove 4, a cleaning ring 6 on the outer side of the drive ring 5, a plurality of guide plates 7 evenly installed between the drive ring 5 and the cleaning ring 6, a plurality of spiral cleaning brushes 8 that cooperate with the outer wall of the protective shell 3 evenly installed on one side of the guide plates 7, an installation groove 9 inside the protective shell 3, transparent shells 10 installed on both sides of the installation groove 9, a photoelectric sensor 11 inside the transparent shell 10, a plurality of sliding grooves 12 on the inner wall of the installation groove 9, a drive mechanism 13 inside the installation groove 9, a cutting blade 14 slidably fitted on the inner wall of the sliding groove 12, and a battery assembly 15 installed on one side of the inner wall of the installation groove 9. The guide plate 7 is fixedly connected to the drive ring 5 and the cleaning ring 6 on both sides, and the guide plate 7 is inclined. When the water flow comes into contact with the outside of the protective shell 3, it impacts the inclined guide plate 7. Since the drive ring 5 and the cleaning ring 6 are fixedly connected to both sides of the guide plate 7, the drive ring 5 will rotate along the ring groove 4. At the same time, the cleaning ring 6 will rotate synchronously. During the rotation, the spiral cleaning brush 8 on one side of the guide plate 7 slides close to the outer wall of the protective shell 3, scraping off the attached aquatic plants, algae and other entangled objects. With the help of the guide groove 16 opened at one end of the protective shell 3, the water flow is guided and the scraped entangled objects are flushed downstream. This process uses the kinetic energy of the water flow to achieve real-time cleaning, avoiding the accumulation of entangled objects from affecting the detection of the photoelectric sensor 11. At the same time, the protective shell 3 provides anti-collision protection for the probe and ensures the stable operation of the equipment.

[0025] In this embodiment, the adjustment mechanism 2 includes a connecting arm 21 hinged to the upper end of the column 1. One end of the connecting arm 21 is hinged to a connecting rod 22. The lower end of the connecting rod 22 is threaded with a ball joint rod 23. The outer side of the ball joint end of the ball joint rod 23 is fitted with a ball joint seat 24 with clearance. One end of the protective shell 3 is threaded into the inner wall of the ball joint seat 24. One end of the protective shell 3 is provided with a plurality of guide grooves 16 at an angle, and one end of the guide grooves 16 faces the outer side of the protective shell 3. A shock-absorbing sleeve 17 is installed on the inner wall of the transparent shell 10. A photoelectric sensor 11 is installed inside the shock-absorbing sleeve 17. Baffles 18 that cooperate with the sliding groove 12 are uniformly fixedly connected to the outer side of the protective shell 3. A base plate 19 is fixedly connected to the lower end of the column 1. Positioning holes 20 are provided at the dead corners of the base plate 19. According to the testing requirements, the position of the protective shell 3 is adjusted by adjusting mechanism 2, and the connecting rod 22 is rotated to move along the thread of ball head rod 23. With the hinge of connecting arm 21 and column 1, and the hinge of connecting arm 21 and connecting rod 22, the height and horizontal position of the protective shell 3 can be changed. The ball head end of ball head rod 23 rotates in the ball head seat 24 with gap, which can finely adjust the angle of the protective shell 3 to ensure that photoelectric sensor 11 is aligned with the testing area. After adjustment, column 1 is fixed through positioning hole 20 of base plate 19 to keep the protective shell 3 in a stable posture. This not only adapts to the testing requirements of different water depths and water flow environments, but also avoids testing errors caused by equipment shaking. At the same time, baffle 18 can prevent impurities from entering the slide 12 and affecting the operation of subsequent components.

[0026] In this embodiment, the drive mechanism 13 includes a mounting plate 131 fixedly connected to the inner wall of the mounting groove 9. A micro motor 132 is mounted on one side of the mounting plate 131. The output end of the micro motor 132 is fixedly connected to a drive disk 133. A plurality of arc-shaped grooves 134 are formed on one side of the drive disk 133. A connecting slide plate 135 is slidably fitted on the outer side of the arc-shaped grooves 134. A guide rod 136 is rotatably fitted on the inner wall of the connecting slide plate 135. The guide rod 136 is slidably fitted on the inner wall of the arc-shaped grooves 134. The outer side of the connecting slide plate 135 is fixedly connected to one end of the cutting blade 14. The micro motor 132 is electrically connected to the battery assembly 15. When the entanglement is stubborn and needs to be actively cleaned, the battery assembly 15 powers the micro motor 132, which drives the drive disk 133 to rotate. The arc groove 134 on the drive disk 133 drives the guide rod 136 to slide. The guide rod 136 pushes the connecting slide plate 135 to move along the slide groove 12. Since the outer side of the connecting slide plate 135 is fixed to the cutting blade 14, the cutting blade 14 slides as a whole, cutting the stubborn water plants and other entanglements on the protective shell 3 or cables. After cutting, the micro motor 132 rotates in reverse to drive the cutting blade 14 to reset. The baffle 18 can limit the sliding range of the cutting blade 14 to prevent it from over-extending and being damaged, effectively dealing with the entanglement problem when the water flow is slow, ensuring the continuous operation of the equipment. Moreover, the cutting blade 14 and the slide groove 12 are sealed and slidingly connected to prevent water from seeping into the mounting groove 9.

[0027] When using the device, first fix the column 1 through the positioning hole 20 of the base plate 19, and operate the adjustment mechanism 2 to adjust the protective shell 3 to the target detection position and angle. After entering the water, the water flow impacts the guide plate 7, which drives the drive ring 5 and the cleaning ring 6 to rotate. The spiral cleaning brush 8 cleans the outer wall of the protective shell 3 in real time. The guide groove 16 assists in guiding and removing debris. If stubborn entanglement is encountered, the battery pack 15 powers the micro motor 132, which is driven by the drive plate 133, the arc groove 134, the guide rod 136, and the connecting slide plate 135 to drive the cutting blade 14 to slide and cut along the slide groove 12. Throughout the process, the protective shell 3 is anti-collision, and the transparent shell 10 and the shock-absorbing sleeve 17 protect the photoelectric sensor 11, achieving the synergy of anti-collision, anti-entanglement and accurate detection, ensuring the stable and efficient operation of the equipment.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
