[0002] Drainage pipes are made of sanitary polyvinyl chloride (PVC) resin as the main raw material, with appropriate amounts of stabilizers, lubricants, fillers, color enhancers, etc. added, and are extruded by a plastic extruder and injection molded by an injection molding machine. The production of pipes and fittings is completed through processes such as cooling, curing, shaping, inspection, and packaging. Drainage pipes are often used in the construction field. During the use of drainage pipes, it is necessary to monitor the drainage pipes so that the operating status of the drainage pipes can be grasped in time, thereby improving the maintenance efficiency of the drainage pipes.

[0003] In order to enable employees to read clearly, the existing intelligent monitoring device for drainage pipe flow is usually installed on the inner wall of the drainage pipe, which monitors the flowing water and provides data, and finally transmits the data to the display screen.

[0004] Although the existing intelligent drainage pipe flow monitoring device can monitor the flow of water in the drainage pipe, it still has some shortcomings. When in use, the monitoring device needs to be in the drainage pipe for a long time during monitoring. At this time, since the water in the drainage pipe contains a large amount of impurities such as domestic garbage and particulate matter, these impurities will continue to accumulate in the monitoring area of ​​the monitoring device, thereby reducing the accuracy of the monitoring results and reducing the efficiency of monitoring.

[0020] Working principle: Step 1, by moving the two clamping plates to the outside of the handrail in the drainage pipe, at this time, the worm gear and the gear are driven to rotate simultaneously by rotating the worm, and when the gear rotates, the two sliders can drive the two clamping plates to approach each other and clamp the handrail through the two rack plates, so that the monitoring mechanism can be fixed to prevent the monitoring mechanism from falling off during use, and the connecting plate, the connecting frame and the U-shaped frame are driven downward at the same time by driving the telescopic cylinder, so that the flow sensor and the water quality sensor can enter the water. While the connecting frame moves downward, the transmission line pulls the roller and the roller drives the T-shaped plate to move. In the process of the movement of the T-shaped plate, the compression spring 1 will be compressed, and the transmission line can be straightened at this time. When the telescopic cylinder drives the connecting frame to move upward, the T-shaped plate can drive the roller to retract the excess transmission line under the action of the compression spring 1, so that the flow sensor and the water quality sensor are always connected to the controller, so as to facilitate the transmission and display of the monitoring results;

At this time, the bottom monitoring area of ​​the flow sensor and the water quality sensor can be cleaned. At the same time, when the motor drives the winding wheel to rotate in the opposite direction, the wire rope can be released. At this time, the brush plate and the flow sensor can be separated from the water quality sensor to prevent the brush plate from blocking the monitoring area of ​​the flow sensor and the water quality sensor;

[0022] Step three, by inserting the connecting disk into the mounting disk, the mounting disk will squeeze the card block while entering, and the card block will move when being squeezed, and the compression spring 2 will be compressed during the movement. When the slot moves to a position parallel to the card block, the card block can be bounced into the slot by the compression spring 2. At this time, the brush plate can be quickly installed, and the positioning ring 1 and the positioning ring 2 can be connected by the spring rod. At this time, the brush plate can be driven to rotate when the impeller rotates. When the brush plate needs to be removed, the spring rod can be compressed by lifting the positioning ring 1 upwards, and the positioning ring 1 and the positioning ring 2 can be separated at the same time. At this time, the pull rope can be used to pull the card block out of the middle of the slot by rotating the T-shaped rod, and the brush plate can be quickly removed.

[0023] The present invention provides a municipal drainage pipeline flow intelligent monitoring device, which has the following beneficial effects:

[0024] 1.

After cleaning, the brush plate can be separated from the flow sensor and the water quality sensor to avoid affecting the monitoring work of the flow sensor and the water quality sensor, thereby improving the accuracy of the monitoring results of the flow sensor and the water quality sensor.

[0025] 2. The present invention can monitor the flow and water quality in the pipeline in real time through the cooperation of the monitoring mechanism and the limiting mechanism, and display the data through the controller to help operation and maintenance personnel quickly respond to pipeline problems or abnormal conditions. At the same time, under the action of the limiting mechanism, the controller can ensure that the controller is continuously connected to the flow sensor and the water quality sensor when the flow sensor and the water quality sensor move downward into the water, and the redundant transmission lines can be folded up when not in use, which can protect the transmission lines and improve the portability of the device.

The other ends of the two transmission lines 109 are respectively fixedly connected with a flow sensor 107 and a water quality sensor 108, which are used to monitor the flow rate and quality and transmit the monitoring results to the controller 101 and display them. The flow sensor 107 and the water quality sensor 108 transmit the monitoring data to the controller 101 through the transmission line 109. The controller 101 analyzes the data and displays the specific parameters of the water flow velocity and the pollutant content.

[0040] The fixing mechanism 20 is arranged outside the monitoring mechanism 10 and is used to fix the monitoring mechanism 10 in the drainage pipe to prevent the monitoring mechanism 10 from falling off. The fixing mechanism 20 is used to firmly fix the monitoring mechanism 10 on the handrail inside the drainage pipe to prevent the monitoring mechanism 10 from falling off and moving, thereby improving the stability of the device and preventing the monitoring mechanism 10 from tilting, thereby improving the accuracy of the monitoring result;

During the monitoring process, the brush plate 305 can be controlled to contact with the flow sensor 107 and the water quality sensor 108 through the adjusting component, so that the surfaces of the flow sensor 107 and the water quality sensor 108 can be cleaned. Then, the brush plate 305 is separated from the flow sensor 107 and the water quality sensor 108 to avoid the brush plate 305 from affecting the flow rate, thereby improving the monitoring effect and further improving the accuracy of the monitoring result.
