Description

Technical Field

[0001] This utility model relates to the technical field of flow monitoring devices, specifically a municipal pipeline flow monitoring device. Background Technology

[0002] Municipal pipeline engineering is a pipeline system engineering project for transporting and distributing industrial water supply and domestic drinking water, as well as collecting, transporting, and discharging industrial wastewater, domestic sewage, and rainwater. Municipal pipeline engineering is an integral part of the water supply and drainage system, playing a vital role in the entire system. It includes the pipeline system itself and various structures along the pipeline. During transport, municipal pipelines are typically equipped with a flow monitoring device to calculate the amount of water being transported.

[0003] According to a public notice (Announcement No.: CN221629525U) of a water supply and drainage pipeline flow monitoring device, the above application uses a protective shell and a protective cover. The protective shell and the protective cover are tightly connected. The protective shell is installed on a fixed pipe, which can prevent the flow monitor from being damaged by collision and prevent rainwater from entering, thus ensuring the service life of the flow monitor. In addition, it is simple to set up, reliable to use and not easily damaged.

[0004] However, in actual use, the water flow in municipal pipelines is often of various types. Some pipelines carry purified water, while others carry unpurified water. Such water carries many impurities, and the equipment requires manual operation of valves to achieve the cleaning effect, which is time-consuming, labor-intensive, and makes it difficult to judge the blockage. In view of this, we propose a municipal pipeline flow monitoring device. Utility Model Content

[0005] The purpose of this invention is to provide a municipal pipeline flow monitoring device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A municipal pipeline flow monitoring device includes a water pipe, a connecting flange fixedly connected to the end of the water pipe, a monitoring box fixedly connected to the side wall of the water pipe, a monitoring device installed inside the monitoring box, an observation window opened on the upper surface of the monitoring box, and a filter device installed inside the water pipe, the filter device comprising:

[0007] A sealing ring is fixedly connected to the inner surface of a connecting flange. A filter screen is fixedly connected to the side of the sealing ring away from the connecting flange. A base is fixedly connected to the side of the filter screen away from the sealing ring. A drive shaft is rotatably connected to the axis of the base. A bushing is fixedly connected to the outer surface of the drive shaft near the sealing ring. A fan blade is fixedly connected to the outer surface of the bushing. A connecting post is rotatably connected to the outer surface of the drive shaft near the sealing ring.

[0010] Preferably, the diameter of the filter screen is smaller than the diameter of the water pipe, and the diameter of the sealing ring is larger than the diameter of the filter screen but smaller than the diameter of the water pipe.

[0011] Preferably, a silicone gasket is fixedly connected to the side of the connecting flange away from the water pipe.

[0014] Preferably, the first spiral spring and the second spiral spring have opposite directions of torsion.

[0015] Compared with the prior art, this utility model provides a municipal pipeline flow monitoring device, which has the following beneficial effects:

[0016] 1. This municipal pipeline flow monitoring device, by being equipped with a filter, can prevent untreated sewage from interfering with or damaging the monitoring device, thus ensuring the service life of the equipment. Furthermore, the fan blades drive the transmission shaft to rotate, which in turn causes the connecting frame and the rotating drum to rotate. Simultaneously, with the action of the spiral spring, this mechanism can perform a certain amount of cleaning work on the filter screen, preventing the filter screen from becoming clogged due to long-term operation, thereby preventing any impact on the accuracy of flow monitoring.

[0017] 2. This municipal pipeline flow monitoring device, through the installation of an auxiliary mechanism, enables the blade to cut through blockages while simultaneously rotating the second spiral spring, allowing the blockages to be flung out and cleared through the filter screen. When encountering blockages that are difficult to cut, the second spiral spring will accumulate energy to cut and clear the blockages, ensuring the smooth flow of the filter screen and thus guaranteeing the normal operation of the flow monitoring device.

[0024] like Figures 1-5As shown, this utility model provides a technical solution: a municipal pipeline flow monitoring device, including a water pipe 1, a connecting flange 11 fixedly connected to the end of the water pipe 1, a monitoring box 12 fixedly connected to the side wall of the water pipe 1, a monitoring device installed inside the monitoring box 12, an observation window 13 opened on the upper surface of the monitoring box 12, and a filter device 2 installed inside the water pipe 1. The filter device 2 includes a filter screen 21, a sealing ring 22, a connecting column 23, a drive shaft 24, a bushing 25, a fan blade 26, a connecting frame 27, a base 28, a fixed shaft 29, a spiral spring 210, and a rotating drum 211.

[0025] In one embodiment of this utility model, the sealing ring 22 is fixedly connected to the inner surface of the connecting flange 11. A filter screen 21 is fixedly connected to the side of the sealing ring 22 away from the connecting flange 11. A base 28 is fixedly connected to the side of the filter screen 21 away from the sealing ring 22. A drive shaft 24 is rotatably connected to the axis of the base 28. A bushing 25 is fixedly connected to the outer surface of the end of the drive shaft 24 near the sealing ring 22. A fan blade 26 is fixedly connected to the outer surface of the bushing 25. A connecting post 23 is rotatably connected to the outer surface of the end of the drive shaft 24 near the sealing ring 22. The end of the connecting post 23 away from the drive shaft 24 is fixedly connected to the inner surface of the sealing ring 22. The end of the connecting frame 27 away from the filter screen 21 is fixedly connected to the outer surface of the drive shaft 24. The inner surface of the connecting frame 27 extends through... A fixed shaft 29 is rotatably connected to the auxiliary mechanism 3. One end of a spiral spring 210 is fixedly connected to the outer surface of the fixed shaft 29, and the other end of the spiral spring 210 is fixedly connected to a rotating drum 211. By setting up a filter device 2, the monitoring device can be prevented from being damaged by unfiltered sewage. This ensures the accuracy of the measurement data and also extends the service life of the equipment. At the same time, while the drive shaft 24 is driven to rotate by the fan blade 26, the connecting bracket 27 fixedly connected to the outer surface of the drive shaft 24 will also clean the filter screen 21 to a certain extent, preventing the filter screen 21 from becoming clogged due to long-term operation. The spiral spring 210 allows the auxiliary mechanism 3 to have a certain revolution angle, resulting in better cutting force.

[0026] In addition, an auxiliary mechanism 3 is provided on the outer surface of the rotating drum 211. The auxiliary mechanism 3 includes a circular groove 31, which is formed on the outer surface of the rotating drum 211. A fixed shaft 32 is rotatably connected to the end of the circular groove 31. One end of a spiral spring 33 is fixedly connected to the outer surface of the fixed shaft 32. A sleeve 34 is fixedly connected to the other end of the spiral spring 33. A blade 35 is fixedly connected to the outer surface of the sleeve 34. By providing the auxiliary mechanism 3, the blade 35 can clean stubborn dirt, such as seaweed and garbage bags, that are clogging the mesh of the filter screen 21. The cut-off blockages will pass through the filter screen 21. The filter will not affect subsequent measurements. At the same time, the rotation of the spiral spring 33 allows the blockage to be thrown out and cleared through the filter screen 21. When encountering blockages that are difficult to cut, the spiral spring 33 will accumulate energy to cut and clear the blockage, ensuring the unobstructed flow of the filter screen 21 and thus ensuring the normal operation of the flow detection device. Furthermore, the diameter of the filter screen 21 is smaller than the diameter of the water pipe 1, and the diameter of the sealing ring 22 is larger than the diameter of the filter screen 21 but smaller than the diameter of the water pipe 1, ensuring that all the water entering the water pipe 1 will be filtered by the filter screen 21, eliminating the possibility of inadequate filtration.

[0027] In this embodiment of the utility model, a silicone gasket is fixedly connected to the side of the connecting flange 11 away from the water pipe 1, which can further ensure that no leakage occurs when the outer pipe is connected to the connecting flange 11, thereby preventing inaccurate flow monitoring. At the same time, multiple sets of connecting brackets 27, fixed shaft 29, spiral spring 210, and rotating drum 211 are arranged in a circumferential array on the outer surface of the transmission shaft 24. Multiple sets of auxiliary mechanisms 3 are also arranged in a circumferential array on the outer surface of the rotating drum 211. The arrangement of multiple sets of connecting brackets 27, fixed shaft 29, spiral spring 210, rotating drum 211 and auxiliary mechanisms 3 can better clean the filter screen 21 and ensure smooth water flow. The spiral spring 210 and spiral spring 33 have opposite twisting directions, which makes the blade 35 have a larger force range when cleaning the filter screen 21, and the applied cutting is also increased, resulting in a better cutting effect.

[0028] In this utility model, when in use, the operator connects the external pipe to the device through the connecting flange 11. The water flow drives the fan blades 26 of the filter screen 21 to rotate the drive shaft 24. The rotating drum 211 and the circumferentially distributed auxiliary mechanism 3 operate synchronously. While the filter screen 21 intercepts impurities in the water flow, the blades 35 on the sleeve 34 scrape off dirt from the surface of the filter screen 21 under the drive of the spiral spring 33, preventing blockage. The gap design between the sealing ring 22 and the water pipe 1 balances the water flow pressure, ensuring that all water flows are filtered. The silicone gasket ensures the seal. The monitoring box 12 displays the flow data in real time through the observation window 13. The filter device 2 can be disassembled and maintained as a whole, realizing self-cleaning monitoring without external energy dependence, and is suitable for long-term stable operation of municipal pipelines.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
