Description

Technical Field

[0001] This utility model relates to the field of wastewater sampling technology, and in particular to an automatic sampling device for wastewater operation and maintenance. Background Technology

[0002] "Wastewater operation and maintenance" usually refers to the entire process of operation management and maintenance of wastewater treatment systems or facilities. Its purpose is to ensure the stable operation of wastewater treatment facilities, meet the standards for effluent quality, and achieve energy conservation, consumption reduction and sustainable operation. Wastewater treatment plants and industrial discharge outlets need to monitor water quality changes in real time. In order to respond to emergencies and trace the source of pollution, it is necessary to regularly sample and test wastewater. However, manual sampling is easily affected by sampling time, location, and operation methods. For example, only surface water is collected, and the sampling volume is inaccurate, which leads to the data not being able to truly reflect the overall water quality. Therefore, it is necessary to propose an automatic sampling device for wastewater operation and maintenance. Utility Model Content

[0018] In this embodiment, when using this device, whenever sampling is required, the sampling bottle 24 needs to be placed on the top surface of the hollow frustum 16 beforehand. Then, the cylinder push rod 20 is operated, and the output end of the cylinder push rod 20 drives the push-pull plate 21 to move, thereby driving a rack 19 to move, which in turn drives the gear 18 to rotate. The rotation of the gear 18 can drive the other rack 19 to move in the opposite direction, thereby driving the two connecting blocks 22 to move closer to each other, thus driving the two clamping plates 23 to stably clamp the sampling bottle 24 between them. Then, the cylinder push rod 11 is operated, and the output end of the cylinder push rod 11 pushes the carrier plate 12 to move upward, thereby driving the top of the sampling bottle 24 to move closer to the bottom of the sampling tube 3. Then, the motor 14 is operated, and the output end of the motor 14 drives the gear 15 to rotate. The rotation of the gear 15 can drive the gear ring 17 to rotate, and the rotation of the gear ring 17 can drive the sampling bottle 24 to rotate. This allows the top of the sampling bottle 24 to be screwed into the inner threaded hole of the sampling tube 3. Then, the cylinder push rod 4 30 is operated, and the output end of the cylinder push rod 4 30 moves the baffle 31, allowing wastewater to flow through the sampling tube 3 into the sampling bottle 24. After sampling is complete, the cylinder push rod 4 30 is operated to return the baffle 31 to its original position. Then, the sampling bottle 24 is screwed out from the bottom of the sampling tube 3. The sampling bottle 24 is then moved downwards, and the cylinder push rod 5 is operated again, with the output end of the cylinder push rod 5... The movable adjustment frame 6 moves to the left, so that the bottle cap 10 is moved directly above the sampling bottle 24. Then, the bottle cap 10 is screwed tightly onto the top of the sampling bottle 24, and the staff waits to remove it. In order to prevent the filter plate 25 from being blocked, the motor 3 26 can be operated. The output end of the motor 3 26 drives the threaded rod 27 to rotate. The rotation of the threaded rod 27 can drive the scraper 28 to move back and forth along the threaded rod 27, thereby cleaning the filter plate 25 and preventing dirt from blocking the filter holes on the filter plate 25.
