The connecting flanges 11 fixedly connected at both ends can be stably connected with external pipelines through connecting members such as bolts, ensuring smooth flow of water in and out of the water meter and realizing accurate flow measurement.

[0031] Please refer to the drawings as shown in the accompanying Figure 1 - the accompanying Figure 6As shown, the bottom of the device shell 1 is fixedly connected with a first fixed support 13, and the top of the device shell 1 is provided with a cleaning mechanism 3; the cleaning mechanism 3 comprises a gear ring 301, a group of scraping strips 302 are fixedly connected to the bottom of the gear ring 301, and a rotating handle 303 is fixedly connected to the top of the gear ring 301; the cleaning device shell 12 is an installation carrier of the pipeline cleaning mechanism 2, and provides a relatively independent working space for the pipeline cleaning mechanism 2; the first gear 201 in the pipeline cleaning mechanism 2 can transmit rotary motion to the transmission rod 202 below under the meshing transmission of the gear ring 301, not only drives the rotating disc 203 to rotate to realize power transmission, but also converts the rotary motion into linear motion through the second gear 204 at the bottom to interact with the rack 205, so that the scraping plate 206 at both ends of the rack 205 slides along the inner wall of the cleaning device shell 12, effectively scrapes off dirt and impurities on the inner wall of the pipeline, ensures the smoothness of the pipeline, and the second fixed support 207 provides stable sliding support for the rack 205, and ensures the motion accuracy of the scraping plate 206 during cleaning. The first fixed support 13 is fixed at the bottom of the device shell 1, stably supports the water meter in the installation position, prevents displacement or shaking of the water meter during use, the gear ring 301 of the cleaning mechanism 3 is the core driving component of the entire cleaning action, and the operator can easily rotate the gear ring 301 through the rotating handle 303 at the top. A group of scraping strips 302 are fixedly connected to the bottom of the gear ring 301, and can clean the inner wall of the device shell 1 and the outer wall of the metering mechanism 4 in all directions when the gear ring 301 rotates, effectively remove dirt, keep the inside of the water meter clean, and ensure the accuracy of metering.

[0032] Please refer to the accompanying drawings Figure 1 - the accompanying drawings Figure 6 As shown, the inside of the device shell 1 is provided with a metering mechanism 4, and the top of the metering mechanism 4 is fixedly connected with a counting mechanism 5; the metering mechanism 4 is a core metering component of the water meter, which converts the physical quantity of water flow into mechanical motion by sensing the flow rate and flow of water flow, and the counting mechanism 5 fixed at the top of the metering mechanism 4 can accurately record the motion information transmitted by the metering mechanism 4 and present it to the user in the form of intuitive numbers or pointers, so that the user can clearly understand the water consumption.

[0033] Please refer to the accompanying drawings Figure 1 - the accompanying drawings Figure 6 As shown, the outer wall of each cleaning device shell 12 is fixedly connected with a sealing pipe 14, the sealing pipe 14 is fixedly connected to the outer wall of the cleaning device shell 12, and the inner wall thereof is rotatably connected with the outer surface of the rotating disc 203; while ensuring that the rotating disc 203 can freely rotate to transmit power, a good sealing structure is formed to prevent water flow from leaking from the rotating part, and the normal operation and metering accuracy of the water meter are ensured.

[0034] Please refer to the accompanying drawings Figure 1 - the accompanying drawings Figure 6As shown, the inner wall of each sealing pipe 14 and the outer surface of the rotating disc 203 are rotationally connected, which ensures that the rotating disc 203 can rotate freely and stably when transmitting power, and cannot be stuck due to poor connection, ensuring that power is smoothly transmitted from the transmission rod 202 to subsequent components, thereby ensuring the normal movement of the scraper 206, realizing efficient pipeline cleaning. From the sealing performance, it builds a good sealing structure, effectively preventing water leakage from the rotating part, which not only avoids the waste of water resources, but also prevents the surrounding environment from being damp and corroded due to water leakage, ensuring the long-term stable operation of the water meter and maintaining the measurement accuracy.

This connection provides stable support for the entire pipeline cleaning operation. The second fixed support 207 is like a solid track, and the rack 205 can only slide linearly under its restriction, ensuring the accuracy of the movement direction. In this way, when the scraper 206 cleans the dirt and impurities on the inner wall of the pipeline, it can move accurately along the set path, avoiding incomplete cleaning due to deviation of the movement trajectory, greatly improving the cleaning effect and movement accuracy, and ensuring efficient execution of the pipeline cleaning work.

When the operator rotates the rotating handle 303 to drive the gear ring 301 to rotate, the gear ring 301 can accurately and efficiently transmit power to the first gear 201. Due to the characteristics of gear meshing, the power transmission process is stable and reliable, ensuring the accuracy of the transmission ratio. This enables accurate adjustment of the movement speed and cleaning intensity of the scraper 206 according to actual needs by controlling the rotation speed and amplitude of the rotating handle 303, achieving flexible and efficient pipeline cleaning operation.

This double attachment design achieves a full range of cleaning effects. When the gear ring 301 rotates, the scraper 302 can simultaneously clean the inner wall of the equipment shell 1 and the outer wall of the metering mechanism 4, preventing the accumulation of dirt in these key parts. Cleaning the inner wall of the equipment shell 1 prevents corrosion of internal components, extending the service life of the equipment.
