Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically an automatic cleaning device applied to online water quality monitoring instruments. Background Technology

[0002] Online water quality monitoring instruments are widely used in water treatment plants, waterworks, sewage treatment plants, rivers, lakes, and other environments for water body monitoring and management. These devices can monitor a range of key water quality parameters in real time, including but not limited to pH, turbidity, dissolved oxygen (DO), conductivity (EC), and ammonia nitrogen (NH3-N) concentration.

[0003] In practical applications, online water quality monitoring instruments typically measure the aforementioned parameters by placing the probe in water. However, since the probe needs to be immersed in water for extended periods, biological and non-biological deposits inevitably accumulate on its outer wall. If these deposits are not removed promptly, they will directly affect the accuracy of the probe's measurement data, thereby impacting the assessment of water quality. The traditional cleaning method involves manually cleaning the probe using cleaning tools (such as a cleaning brush) after removing it from the water. This method is not only inconvenient and increases maintenance costs, but also prone to delays in cleaning, thus affecting the reliability and timeliness of the monitoring results. To address these issues, this invention proposes an automatic cleaning device for online water quality monitoring instruments. Utility Model Content

[0028] 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.

[0029] Example: Please refer to Figures 1 to 4According to an embodiment of this utility model, an automatic cleaning device for use on an online water quality monitoring instrument is provided. This device is installed on the probe 2 of the online water quality monitoring instrument. The automatic cleaning device includes a housing 1, a cleaning ring 5, and a cleaning component. The housing 1 covers the probe 2 and has evenly distributed water passage holes 4. The housing 1 protects the probe 2, and the water passage holes 4 ensure that water flows through the probe 2 while preventing impurities such as stones from damaging it under the impact of the water flow. The cleaning ring 5 is located inside the housing 1 and sleeved on the outside of the probe 2. A first brush bristle 6 is fixedly installed on the inner side of the cleaning ring 5; the bristles are flexible. The cleaning component includes a reciprocating screw 8 threadedly engaged with the cleaning ring 5 and a motor 9 driving the reciprocating screw 8 to rotate. The motor 9 is specifically a waterproof motor. The housing of the motor 9 is fixed to the top of the housing 1. The output shaft of the motor 9 is coaxially and fixedly connected to the reciprocating screw 8. The motor 9 is electrically connected to an external power source via a timer switch. Both the timer switch and the power source can be located on land and connected to the motor 9 via wires.

[0030] The automatic cleaning device for online water quality monitoring instruments with the above structure controls the timed start and stop of the motor 9 through a timer switch. When the motor 9 starts, the reciprocating screw 8 drives the cleaning ring 5 to move back and forth along the length of the probe 2. The first bristles 6 located inside the cleaning ring 5 can brush off the adhering substances on the outside of the probe 2, thus achieving the effect of automatic cleaning of the probe 2.

[0031] It should be noted that, in order to avoid the cleaning ring 5 from obstructing the normal monitoring of the water by the probe 2, after cleaning, the cleaning ring 5 can be left in a position that does not contact the probe 2, so as not to affect the normal monitoring of the water by the probe 2.

[0032] During use, the water passage hole 4 of the outer casing 1 may be blocked by aquatic plants or other debris. If the water passage hole 4 is blocked, it will affect the normal flow of water through the probe 2, thus affecting the monitoring results. Therefore, in this exemplary embodiment, the water passage hole 4 is located on the side wall of the outer casing 1, and a second brush bristle 7 is fixedly provided on the outer side of the cleaning ring 5, which is in contact with the side wall of the outer casing 1. With this arrangement, while the first brush bristle 6 on the inner side of the cleaning ring 5 cleans the probe 2, the second brush bristle 7 on the outer side of the cleaning ring 5 can also clean the water passage hole 4 on the outer casing 1, reducing the possibility of the water passage hole 4 being blocked.

[0033] In this exemplary embodiment, a positioning rod 10 parallel to the reciprocating lead screw 8 is fixedly disposed inside the housing 1, and the positioning rod 10 movably passes through the cleaning ring 5. The positioning rod 10 serves as a guide, providing more stable guiding support for the movement of the cleaning ring 5, thereby achieving a better cleaning effect.

[0034] In this exemplary embodiment, a drain port 11 is provided at the bottom of the outer casing 1, and a cover plate 12 is elastically provided at the drain port 11. Specifically, both sides of the cover plate 12 are elastically connected to the drain port 11 through an elastic structure. A flange 19 is provided protruding from the outer side of the drain port 11. The elastic structure includes a pull rod 20 and a spring 22. One end of the pull rod 20 is fixed to the cover plate 12, and the other end of the pull rod 20 movably passes through the flange 19 and is fixedly provided with a shaft platform 21. A spring 22 is sleeved on the outside of the pull rod 20 located between the shaft platform 21 and the flange 19. A drive shaft 13 is rotatably connected to the reciprocating screw 8 inside the drain port 11. Specifically, the drive shaft 13 is rotatably connected to the inner wall of the outer casing 1 through a connecting structure. Specifically, the drive shaft 13 is connected to the reciprocating screw 8 through a gear set. Preferably, the gear set includes a driving gear 17 and a driven gear 18 that mesh with each other. The driving gear 17 is fixed on the reciprocating screw 8, and the driven gear 18 is fixed on the drive shaft 13. Furthermore, the connection structure includes a bearing 15 and a connecting rod 16. The inner ring of the bearing 15 is fixed to the drive shaft 13, and the outer ring of the bearing 15 is fixedly connected to the outer casing 1 via the connecting rod 16. A blade 14 is fixedly installed on the outside of the drive shaft 13. With this configuration, when the reciprocating screw 8 drives the cleaning ring 5 to move, the reciprocating screw 8 can also drive the drive shaft 13 and the blade 14 to rotate via the gear set. When the blade 14 rotates, it can push the water inside the outer casing 1 to flow towards the drain port 11. The cover plate 12 at the drain port 11 opens under water pressure. At this time, the debris and other impurities cleaned from inside the outer casing 1 can be discharged through the drain port 11 to prevent the debris from accumulating inside the outer casing 1 and affecting the normal monitoring of the probe 2.

[0035] To facilitate the installation of the probe 2 inside the housing 1, in this exemplary embodiment, the upper end of the housing 1 is provided with a mounting hole 23 for the probe 2 to pass through. The probe 2 is detachably fixed to the mounting hole 23 by a fixing structure. Specifically, the fixing structure includes two arc-shaped clamping blocks 24. The clamping blocks 24 are connected to the housing 1 located on both sides of the mounting hole 23 via a connecting rod 25 rotating plate. The two clamping blocks 24 are fixed together by bolts or cable ties. When installing the probe 2, the probe 2 is inserted into the housing 1 through the mounting hole 23. Then, the two clamping blocks 24 are clamped on both sides of the transmission line 3 of the probe 2. Finally, the two clamping blocks 24 are fixed together with bolts or cable ties to fix the probe 2. When removing the probe 2, the probe 2 can be removed simply by contacting the fixing between the two clamping blocks 24.
