A device for detecting pollution in water bodies within pipes

Abstract

This invention provides a device for detecting water pollution in pipelines, comprising a detection structure including a detection shell and a rotating tube. The detection shell is threadedly connected to the inner wall of a threaded chamber. A liquid chamber is formed inside the detection shell, and a detector is installed inside the liquid chamber. Auxiliary grooves are formed at the top and bottom of the detection shell. The rotating tube is rotatably connected to the inside of the detection chamber. This invention is rationally designed. Through a movable wastewater stirring structure, when it moves downwards, the inlet groove is closed, and the auxiliary grooves are sealed against the inner wall of the rotating tube, allowing wastewater to flow inside the pipeline body and shutting off the detection. Conversely, when the inlet groove is opened, the wastewater flows through the detector and then re-enters the pipeline through the connecting pipe. This eliminates the need for manual wastewater sampling and allows for real-time detection of wastewater flowing inside the pipeline body.

Description

Technical Field

[0001] This invention mainly relates to the field of water pollution detection, specifically to a device for detecting water pollution in pipelines. Background Technology

[0002] In water quality management of municipal water supply and drainage networks, industrial water transmission pipelines, and sewage pipelines, the detection of pollution indicators in the water inside the pipelines is a key means of understanding water quality and preventing the spread of pollution. Currently, pollution detection in pipeline water generally employs a portable, manual approach: operators open a pre-set detection port or maintenance valve on the pipeline, manually insert the detection probe and its associated sensing components into the pipeline cavity, and collect data after the readings stabilize. After each test, the entire detection device must be completely removed from the pipeline, and the insertion process is repeated for the next test.

[0003] Each inspection requires re-inserting the detection device into the pipeline, a cumbersome process that results in lengthy inspection times and reliance on manual on-site work. This leads to low efficiency, high labor costs, and makes it unsuitable for the routine inspection needs of long-distance, large-scale pipeline networks. Furthermore, some existing online detection devices are exposed to the sewage environment inside the pipeline for extended periods, causing impurities to easily adhere to the detector surface, affecting detection accuracy and response speed.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve: This invention provides a device for detecting water pollution in pipelines, thereby solving the technical problems existing in the background art.

[0006] 2. Technical Solution: To achieve the above objectives, the technical solution provided by the present invention is as follows: a device for detecting water pollution in a pipeline, comprising a pipeline connection structure, wherein a sewage mixing structure is slidably connected inside the pipeline connection structure, and a detection structure is provided inside the sewage mixing structure, wherein the number of detection structures is set to multiple, and the multiple detection structures are arranged in a ring array inside the pipeline connection structure. A wastewater mixing structure includes an electric telescopic rod and a magnetic ring. The output end of the electric telescopic rod is provided with a detection chamber. A connecting pipe is provided on one side of the top of the detection chamber. A threaded cavity is opened on the outer wall of the detection chamber. The detection structure includes a detection shell and a rotating tube. The detection shell is threaded to the inner wall of the threaded chamber. A liquid chamber is opened inside the detection shell. A detector is installed inside the liquid chamber. Auxiliary grooves are opened at the top and bottom of the detection shell. The rotating tube is rotatably connected to the inside of the detection chamber. A flow guide groove is opened on the outer wall of the rotating tube. A toothed ring is provided on one side of the rotating tube.

[0007] Furthermore, the pipe connection structure includes a pipe body, with connecting flanges at both ends of the pipe body, threaded holes inside the connecting flanges, a liquid inlet hole on one side of the top of the pipe body, and a guide plate on the inner wall of the pipe body, the guide plate being positioned directly below the liquid inlet hole.

[0008] Furthermore, the bottom of the pipe body is provided with an installation compartment, the top of the pipe body is provided with a placement compartment, a connection hole is provided on one side of the pipe body, a support rod is provided at the bottom of the inner wall of the placement compartment, and a rack is provided at the bottom of the support rod.

[0009] Furthermore, the connecting pipe passes through the connecting hole, one end of the connecting pipe is connected to the liquid inlet hole, the outer wall of the detection chamber is provided with a liquid inlet groove, and the bottom of the inner wall of the detection chamber is provided with an auxiliary chamber.

[0010] Furthermore, a support frame is provided on the top of the auxiliary compartment, and a sealing tube is provided on the top of the support frame. Magnetic rings are provided on the top and bottom of the outer wall of the sealing tube.

[0011] Furthermore, a servo motor is provided on the inner wall of the auxiliary compartment, a rotating shaft is provided at the output end of the servo motor, and magnetic rotating disks are provided at both ends of the outer wall of the rotating shaft.

[0012] Furthermore, the magnetic ring is rotatably connected to the inner wall of the guide groove, the outer wall of the magnetic ring is provided with a rotating frame, and a stirring rod is provided between the two rotating frames.

[0013] Furthermore, a threaded ring is provided on one side of the detection shell, and the threaded ring is threadedly connected to the threaded chamber.

[0014] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this invention has the following advantages: This invention features a sewage stirring structure that can be raised and lowered. When the structure moves downward, the inlet tank is closed, and the auxiliary tank is sealed by fitting against the inner wall of the rotating pipe. Sewage flows inside the pipe body, and the detection is turned off. Conversely, when the inlet tank is opened, the sewage flows through the detector and then re-enters the pipe through the connecting pipe. This eliminates the need for manual sampling and testing of the sewage and allows for real-time monitoring of the sewage flowing inside the pipe body. By setting a servo motor 209 in the auxiliary chamber 206, the servo motor 209 drives the rotating shaft 210 and the magnetic rotating disk 211 to rotate. The magnetic rotating disk 211 drives the magnetic ring 213 to rotate in the guide groove 212 through magnetic non-contact drive. The magnetic ring 213 drives the rotating frame 214 and the stirring rod 215 to rotate, stirring the sewage in the detection chamber 202. At the same time, the sewage is in full contact with the detector 304, and the water flow disturbance is used to wash the surface of the detector 304 to prevent impurities from adhering and depositing, thus ensuring the detection accuracy and response speed of the detector 304 during long-term operation. During the lifting and lowering process, the sewage mixing structure 2 synchronously drives the rotating tube 306 of the detection structure 3 to rotate. When the detection chamber 202 moves upward, the toothed ring 307 meshes with the rack 110, causing the rotating tube 306 to rotate on the outer wall of the detection shell 301. The guide channel 308 and the auxiliary channel 305 are automatically aligned and connected. The stirring rod 215 simultaneously stirs the sewage entering the detection chamber 202, realizing the fully automated collaborative operation of water intake, stirring, detection and return. No additional control logic is required, and the structure is compact and reliable. Multiple detection structures are arranged in a ring array inside the detection chamber 202, which can simultaneously install multiple or multiple sets of the same detectors 304 to achieve synchronous and comprehensive detection of different pollution indicators in water, such as pH value, turbidity, chemical oxygen demand, heavy metal content, etc., with a wide detection coverage and high data reliability.
