Description

Technical Field

[0001] The present invention relates to the technical field of water meters, in particular to an Internet of Things (IoT) intelligent water meter. Background Art

[0002] The IoT smart water meter is a new type of water meter that integrates IoT technology. The IoT smart water meter can accurately measure water consumption in real time through built-in sensors and communication modules. The sensors can accurately sense the amount of water flowing through and convert the data into digital signals. The communication module can transmit these data to the remote management platform to achieve real-time monitoring and analysis of data. This smart water meter has many advantages. First, it provides a high degree of accuracy and can accurately measure the use of each drop of water, avoiding the measurement errors that may occur in traditional water meters. Secondly, through the remote communication function, the water supply department can understand the user's water use in real time and promptly discover abnormal water use behaviors, such as water leakage, so as to quickly take measures to deal with them and reduce the waste of water resources. At the same time, the IoT smart water meter also supports remote meter reading, without the need for manual door-to-door meter reading, which effectively improves work efficiency and reduces labor costs. In addition, users can also connect to the management platform through smart devices such as mobile phones to view their own water use in real time, better understand the water use rules, and make reasonable water use plans;

[0003] The Chinese patent with the announcement number "CN215726187U" discloses an IoT smart water meter, which includes a pipe body, a base, a connection plate, a shell, a dial, a pipe clamp, a support seat, a sleeve, a ring and a filter. The above device can separate the connection plate from the shell by rotating the bolt, and the pipe clamp from the pipe body by rotating the screw on the pipe clamp. It is not necessary to disassemble the pipe body and destroy the overall structure of the device, so the installation and disassembly of the device is realized. By moving the ring to the right, it can be taken out of the pipe body together with the sleeve, which is convenient for replacement, and it is worth promoting vigorously;

[0004] During the actual application, although the above-mentioned IoT water meter has a certain filtering function, there are some obvious problems in the specific use process. From the actual situation, when the water flows through the water meter, the impurities in the water will gradually adhere to the surface of the filter. With the passage of time, the continuous accumulation of these impurities will inevitably cause the filter to be blocked. On the one hand, the filter is set in the water meter, which will reduce the water flow speed inside the pipe body to a certain extent, thereby affecting the normal water use. With the continuous accumulation of impurities, the filter is blocked, and this situation will be further aggravated, seriously affecting the passage of water. On the other hand, the sheet filter with the same diameter as the inner diameter of the pipe body currently used has a relatively small overall filtering area. In this case, on the one hand, the filtering area is limited and cannot fully meet the filtering needs of a large amount of water flow; on the other hand, with the continuous attachment of impurities, the filtering area will be further reduced, which will not only affect the speed of the water flow, but also may cause the water pressure to decrease, affecting the normal water demand. In summary, it can be seen that the above-mentioned existing device has certain defects and deficiencies in the filtering function, so it is urgent to improve it to improve its filtering effect and performance and better meet the actual needs of users.

[0035] The working principle of the present invention is as follows: in the present invention, by setting the filtering mechanism 3, when the water flows into the water collecting box 1 through the conical connecting bucket 21 on one side during use of the device, the filter cylinder 331 can effectively filter the water flow, thereby filtering out impurities in the water, and achieving a good protection effect on the IoT smart water meter. During use, after the water flows through the filter cylinder 331 for filtration, it will directly contact the spiral leaves 322 in a spiral twisted shape. At this time, the flow of water will drive the spiral leaves 322 to rotate, and the rotation of the spiral leaves 322 will in turn drive the rotating disk 321 to rotate. The rotation of the rotating disk 321 will drive the cleaning plate 323 and the cleaning brush 324 inside it to rotate around the filter cylinder 331. Through the rotation of the cleaning brush 324, the outer surface of the filter cylinder 331 can be fully cleaned. In this process, after the water flows through the filter cylinder 331 for filtration and screening, it will enter the filter cylinder 331. Inside, then, it flows through the water hole 325 on the turntable 321 to the detection end of the IoT smart water meter body 4, and the water flow is detected by the detection end of the IoT smart water meter body 4. At the same time, the water flow can continue to be discharged through the conical connecting bucket 21 at the output end of the water collecting box 1. It can be seen that the device as a whole adopts the setting of a cylindrical filter screen, which has a larger filtering area, and the circulation of water flow can drive the spiral blade 322 to rotate. The rotation of the spiral blade 322 can drive the turntable 321 to drive the cleaning brush to clean the outer wall of the arc-shaped filter screen cylinder 331. It can be seen that the device can automatically clean with the flow of water during the overall application. Therefore, on the one hand, the device has a larger overall filtering area, and on the other hand, it has a strong self-cleaning ability, which can minimize the influence of the filter screen filtration on the internal flow velocity of the water collecting box 1, which not only maintains high filtering efficiency, but also minimizes the influence on the water flow velocity.

[0036] In the present invention, by arranging the cleaning component 32 and the collecting component 34 to cooperate with each other, during the flushing of the water flow, the spiral blade 322 can drive the turntable 321 to rotate under the drive of the water flow, and the rotation of the turntable 321 can drive the cleaning brush 324 to brush and clean the surface of the filter cylinder 331. After the brushing and cleaning is completed, the removed impurities will fall downward. At this time, the impurities can fall into the interior of the arc-shaped guide frame 341. Since the bottom of the arc-shaped guide frame 341 is connected to the interior of the collecting box 342, the removed impurities can be discharged into the collecting box 342 through the arc-shaped guide frame 341. If the inside of the collecting box 342 needs to be cleaned, the sealing cover 344 at the bottom of the guide bucket 343 needs to be twisted to open, and the impurities can be discharged from the inside of the guide bucket 343. If the filter screen cartridge 331 needs to be disassembled, the hand-tightened screws 333 on both sides of the upper end of the sealing plate 332 need to be twisted. When the hand-tightened screws 333 are separated from the inner side of the mounting hole 334, the filter screen cartridge 331 can be quickly disassembled and replaced. This design makes the device as a whole easy to quickly clean the filtered dust and impurities, and is convenient for inspection, maintenance and cleaning, which can further increase the overall service life of the device.

[0037] In the present invention, by providing the mounting mechanism 2, the device can be connected to an external water supply pipe through the connecting flange 258 during use. At this time, the connecting pipe 24 can be inserted into the interior of the sleeve 22. During the insertion of the connecting pipe 24, the button sleeve 256 can be twisted. The rotation of the button sleeve 256 can drive the sliding ring 253 to rotate. The rotation of the sliding ring 253 can drive the torsion spring 252 to tighten. At the same time, the arc rod 255 at the end of the limiting rod 254 rotates. When the connecting pipe 24 is inserted, the button sleeve 256 is released, the torsion spring 252 is reset, and the sliding ring 253 can be reset and rotated, and the sliding ring 253 can drive the limiting rod 254 to drive the arc rod 255 to rotate. The arc rod 255 and the arc limiting sleeve 251 are both in contact with the torsion spring. 252 is arranged in concentric circles, so as the slip ring 253 is reset, the arc rod 255 can be stably inserted into the interior of the arc limit sleeve 251. At this time, the arc limit sleeve 251 can be inserted and clamped with the arc limit rod 254, and the connecting pipe 24 can be stably clamped. If disassembly is required, it is only necessary to twist the button sleeve 256 to drive the slip ring 253 to rotate, and then the arc rod 255 at the end of the connecting rod can be pulled out of the arc limit sleeve 251. At this time, the connecting pipe 24 can be pulled out from the inside of the sleeve 22. It can be seen that the device as a whole is convenient for quick disassembly and assembly of the water collecting box 1, and the whole does not require bolt-assisted installation, which is convenient and quick to disassemble and overhaul, and can further improve the convenience of using the device, which is very worthy of promotion and application.
