[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to Figure 1 , Figure 3 and Figure 5 , an embodiment provided by the present invention: a novel water meter anti-blocking device, including a water meter body 1, a water inlet pipe 3 is fixedly connected to one side of the outside of the water meter body 1, a water outlet pipe 4 is fixedly connected to the other side of the outside of the water meter body 1, a filter box 5 is fixedly connected to the outer side of the water inlet pipe 3, a first filter screen 6 and a second filter screen 8 are respectively inserted into the inner wall of the filter box 5, two sealing grooves 11 are opened on the inner wall of the filter box 5, sealing rings 10 are fixedly connected to the outer sides of the first filter screen 6 and the second filter screen 8, the two sealing rings 10 are respectively matched with the corresponding sealing grooves 11, a connection plate 9 is fixedly connected to the tops of the first filter screen 6 and the second filter screen 8, two first clamping grooves 16 are fixedly connected to the outer side of the connection plate 9, two fixed shells 12 are fixedly connected to the top of the filter box 5, a movable plate 13 is slidably connected to the inner wall of the fixed shell 12, a pull rod 14 is fixedly connected to one side of the movable plate 13, a clamping post 15 is fixedly connected to the other side of the movable plate 13, a spring 17 is sleeved on the outer side of the pull rod 14, the clamping post 15 is matched with the shape of the first clamping groove 16, and the two clamping posts 15 are respectively inserted and matched with the corresponding first clamping grooves 16. An intelligent sensor 2 is fixedly connected to the top of the water meter body 1.

[0035] Specifically, the intelligent sensor 2 can collect the operation data of the water meter in real time, such as water consumption, water flow rate, etc., and remotely transmit this data to the management platform through the network. The water inlet pipe 3 allows water to flow into the water meter body 1, providing a necessary prerequisite for subsequent metering work. The water outlet pipe 4 allows the water flowing through the water meter to flow out. The first filter screen 6 and the second filter screen 8 form a double filter barrier, greatly enhancing the filtering effect and reliability. To ensure the sealing performance of the water inlet pipe 3, two sealing rings 10 cooperate with the corresponding sealing grooves 11, effectively preventing water from flowing out of the filter box 5 during the process of passing through the water inlet pipe 3. Align the first filter screen 6 and the second filter screen 8 with the slots on the inner wall of the filter box 5. During the insertion process, ensure that the sealing ring 10 on the outer side of the filter screen is aligned with the sealing groove 11 on the inner wall of the filter box 5. Then insert the clamping post 15 into the first card slot 16, and under the elastic force of the spring 17, firmly fix the connecting plate 9. Thus, the first filter screen 6 and the second filter screen 8 are installed in the filter box 5, and can effectively filter the water flowing into the water meter body 1. By pulling the pull plate 18 to drive the pull rod 14, the pull rod 14 drives the movable plate 13 to slide in the fixed shell 12, while compressing the spring 17, causing the clamping post 15 to be pulled out of the first card slot 16, releasing the fixation of the connecting plate 9. Then lift the connecting plate 9 upward through the handle 7, and the first filter screen 6 and the second filter screen 8 can be taken out of the filter box 5, making the disassembly and installation of the filter screen faster and more convenient. At the same time, the structure is reasonable and convenient for people to use.

[0036] Refer to Figure 2 , Figure 6 and Figure 7 , a protection component is provided at the top of the water meter body 1. The protection component is used to protect the intelligent sensor 2. The protection component includes a protective shell 19. The bottom of the protective shell 19 is provided on the top of the water meter body 1. Four corners at the bottom of the protective shell 19 are fixedly connected with positioning posts 20. Positioning grooves 21 are respectively opened at four corners of the top of the water meter body 1. The shapes of the positioning posts 20 and the positioning grooves 21 match. The four positioning posts 20 are respectively inserted and matched with the corresponding positioning grooves 21. Both the left and right sides of the outside of the protective shell 19 are fixedly connected with connecting shells 23. Two second card slots 28 are opened on the inner sides of the connecting shells 23. Both sides of the top of the water meter body 1 are fixedly connected with mounting shells 22. A movable plate 25 is slidably connected to the inner wall of the mounting shell 22. One side of the movable plate 25 is rotatably connected with a bolt 24. The outer parts of the two bolts 24 are respectively threadedly connected inside the corresponding connecting shells 23. The other side of the movable plate 25 is rotatably connected with two connecting rods 26. One end of the connecting rod 26 is fixedly connected with a clamping block 27. The shape of the clamping block 27 matches that of the second card slot 28. The four clamping blocks 27 are respectively inserted and matched with the corresponding second card slots 28.

[0037] Specifically, when installing the protective shell 19, first insert the positioning posts 20 at the four corners of the bottom of the protective shell 19 into the positioning slots 21 at the four corners of the top of the water meter body 1 to achieve preliminary positioning and fixation. Then, rotate the bolt 24. Since the bolt 24 is threadedly connected to the connecting shell 23, the rotation of the bolt 24 will push the moving plate 25 to slide on the inner wall of the installation shell 22. The movement of the moving plate 25 drives the connecting rod 26 to move, so that the clamping block 27 at one end of the connecting rod 26 is inserted into the second card slot 28 inside the connecting shell 23, completing the firm installation of the protective shell 19. When disassembling the protective shell 19, rotate the bolt 24 in the reverse direction to make the moving plate 25 slide in the reverse direction, drive the connecting rod 26 to move, and the clamping block 27 disengages from the second card slot 28 to release the fixation. Then, pull out the positioning posts 20 on the protective shell 19 from the positioning slots 21 to complete the disassembly. This provides physical protection for the intelligent sensor 2, effectively preventing damage to the intelligent sensor 2 caused by external collisions, scratches, dust, etc., and ensuring its normal operation and service life. Through the cooperation of the positioning posts 20 and the positioning slots 21, as well as the insertion of the clamping block 27 and the second card slot 28, the double fixation method ensures that the protective shell 19 will not loosen or fall off easily during use.

[0038] Refer to Figure 1 , Figure 3 and Figure 4 One end of each of the two springs 17 is fixedly connected to the outside of the corresponding movable plate 13, and the other end of each of the two springs 17 is fixedly connected to the inner wall of the corresponding fixed shell 12. A handle 7 is fixedly connected to the top of the connecting plate 9, and a pull plate 18 is fixedly connected to the outer sides of the two pull rods 14.

[0039] Specifically, when the pull rod 14 is not pulled, the elastic force of the spring 17 keeps the clamping post 15 inserted into the first card slot 16, ensuring that the filter screen is stably fixed in the filter box 5. When disassembling or installing the filter screen, the operator can hold the handle 7 to lift or lower the connecting plate 9, making it easier to disassemble and install the filter screen. The pull plate 18 increases the contact area with the hand, making it easier and more labor-saving to pull the pull rod 14 and facilitating the operation of the operator.

[0040] Working principle: When water flows into the water meter body 1 through the water inlet pipe 3, it first passes through the filter box 5. The filter screen one 6 and the filter screen two 8 in the filter box 5 play a role in filtering impurities. The impurities are intercepted on the filter screen one 6 and the filter screen two 8, thus preventing impurities from entering the water meter body 1 and causing blockage, and the filtering effect is better than that of a single filter screen. When it is necessary to disassemble the filter screen for cleaning or replacement, by pulling the pull plate 18 to drive the pull rod 14, the pull rod 14 drives the movable plate 13 to slide in the fixed shell 12, and at the same time compresses the spring 17, so that the clamping column 15 is pulled out from the clamping groove one 16, releasing the fixation of the connecting plate 9. Then, by lifting the connecting plate 9 with the handle 7, the filter screen one 6 and the filter screen two 8 can be taken out from the filter box 5, making the disassembly and installation of the filter screen faster and more convenient. At the same time, the structure is reasonable and convenient for people to use. The intelligent sensor 2 on the top of the water meter body 1 is protected by the protective shell 19. When installing the protective shell 19, the positioning columns 20 at the four corners of the bottom of the protective shell 19 are inserted into the positioning grooves 21 at the four corners of the top of the water meter body 1 to achieve preliminary positioning. Then, rotate the bolt 24. The bolt 24 rotates in the internal thread of the connecting shell 23, pushing the moving plate 25 to slide in the installation shell 22. The moving plate 25 drives the connecting rod 26 to move, so that the clamping block 27 is inserted into the clamping groove two 28, thereby firmly fixing the protective shell 19 on the top of the water meter body 1, playing a physical protection role for the intelligent sensor 2 and effectively reducing the risk of damage to the intelligent sensor 2. When disassembling the protective shell 19, rotate the bolt 24 in the reverse direction to make the clamping block 27 disengage from the clamping groove two 28, and then the protective shell 19 can be removed.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
