Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and more specifically, to an Internet of Things (IoT) water meter with an antifreeze structure. Background Technology

[0002] A water meter is an instrument that measures water flow, mostly the cumulative flow. In some cold climates, temperature drops can cause the water inside an outdoor water meter to freeze. Since the volume inside the water meter is limited, the expansion of the frozen water can cause the water meter to crack and be damaged. Therefore, anti-freeze structures are installed on water meters to extend their service life.

[0003] A search revealed a prior art water meter with an antifreeze structure, patent publication number CN219757435U. The specification states that the protective mechanism works by expanding the volume of the water as it freezes inside the meter, pushing a movable block downwards. This increases the space inside the meter, preventing the expansion of the frozen water from damaging it.

[0004] However, in actual use, the water meter is kept in operation by thawing. This means that the water meter will still freeze and be damaged. Furthermore, thawing takes time, making the antifreeze structure less economical to use. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an Internet of Things water meter with an anti-freeze structure, so as to solve the problem that the water meter can still freeze and be damaged in the existing anti-freeze structure, and the thawing takes a certain amount of time, making the use of the above-mentioned anti-freeze structure less economical.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an IoT water meter with an antifreeze structure, comprising a water meter body, an outer placement groove, an inner insulation ring, a plurality of limiting blocks fixedly connected inside the insulation ring, the limiting blocks being inserted into the placement groove, two connecting grooves being formed inside one end of the insulation ring, two connecting blocks being fixedly connected to the other end of the insulation ring, the connecting blocks being slidably connected inside the connecting groove, a slot being formed on one side of the inner wall of the connecting groove, a locking block being locked inside the slot, the locking block being slidably connected through the connecting block inside the other end of the insulation ring.

[0007] The inner wall of the connecting groove has an installation groove on the other side. The end of the locking block away from the groove is fixedly connected to an installation piece. The end of the installation piece away from the locking block is fixedly connected to a pull rope. The end of the pull rope away from the installation piece is fixedly connected to a rotating rod. An elastic element is sleeved on the outside of the pull rope.

[0008] The insulating collar has two slots on its right side and two sliding grooves on its right side. An elastic element 2 is fixedly connected to the inner wall of the sliding groove. A pressing block is fixedly connected to the other end of the elastic element 2. An insert block is fixedly connected to the end of the pressing block away from the elastic element 2. A pulling block is fixedly connected to the right side of the pressing block.

[0009] The card block is slidably connected inside the mounting groove, the mounting plate is slidably connected inside the mounting groove, and the pull rope is slidably connected inside the mounting groove.

[0010] One end of the elastic element is fixedly connected to the mounting plate, and the other end of the elastic element is fixedly connected to the inner wall of the mounting groove.

[0011] The rotating rod is rotatably connected inside the heat-insulating sleeve, the extrusion block is slidably connected inside the slide groove, and the pulling block is slidably connected inside the slide groove.

[0012] One end of the insert is engaged with the inside of the slot, and the other end of the insert is slidably connected to the inside of the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: an IoT water meter with an antifreeze structure, including a water meter body 1, an outer groove 2, and an inner insulating ring 3. The groove 2 provides installation space for the insulating ring 3. Multiple limiting blocks 4 are fixedly connected inside the insulating ring 3, and these limiting blocks 4 are inserted into the groove 2 to limit the insulating ring 3. A heating band is installed on the inner side of the insulating ring 3. The outer shell adopts a double-layer vacuum structure, with polyurethane foam insulation material filling the middle to reduce heat loss. The meter cover... The built-in reflective aluminum foil layer further isolates cold air. Two connecting grooves 5 are opened inside one end of the insulation ring 3, and two connecting blocks 6 are fixedly connected to the other end of the insulation ring 3. The connecting blocks 6 are slidably connected inside the connecting grooves 5. The connecting grooves 5 limit the connection blocks 6, so that the connection blocks 6 can be installed stably. A slot 7 is opened on one side of the inner wall of the connecting groove 5. A slot 8 is engaged inside the slot 7. The slot 8 passes through the connection blocks 6 and is slidably connected inside the other end of the insulation ring 3, so that the insulation ring 3 can be conveniently installed inside the placement slot 2.

[0025] When the insulation ring 3 needs to be installed, the insulation ring 3 is placed inside the placement groove 2, so that the limiting block 4 can be inserted into the placement groove 2. Then, the two ends of the insulation ring 3 are brought together, so that the connecting block 6 can slide into the connecting groove 5. Then, the locking block 8 is moved outward, so that the locking block 8 can pass through the connecting block 6 and engage with the inside of the locking groove 7, thereby limiting the connection block 6 and making the insulation ring 3 easy and stable to install.

[0026] Example 2: Based on Example 1, in order to facilitate the pulling of the locking block 8, an installation groove 9 is provided on the other side of the inner wall of the connecting groove 5. The locking block 8 is slidably connected to the inside of the installation groove 9. The installation groove 9 provides moving space for the locking block 8. An installation piece 10 is fixedly connected to the end of the locking block 8 away from the locking groove 7. The installation piece 10 is slidably connected to the inside of the installation groove 9. The installation groove 9 limits the installation piece 10, allowing it to slide smoothly. A pull rope 11 is fixedly connected to the end of the installation piece 10 away from the locking block 8. The pull rope 11 is slidably connected to the inside of the installation groove 9. The installation groove 9 limits the pull rope 11, preventing it from deviating during sliding. A rotating rod 13 is fixedly connected to the end of the pull rope 11 away from the installation piece 10. An elastic element 12 is sleeved on the outside of the pull rope 11. One end of the elastic element 12 is fixedly connected to the installation piece 10, and the other end of the elastic element 12 is fixedly connected to the inner wall of the installation groove 9.

[0027] When the locking block 8 needs to be pulled, the rotating rod 13 is rotated so that one end of the pull rope 11 is wound around it, and the other end of the pull rope 11 pulls the mounting plate 10 to compress the elastic element 12 and deform it. This causes the mounting plate 10 to pull the locking block 8 into the mounting groove 9. Conversely, by releasing the rotating rod 13, the elastic element 12 is reset, which pushes the mounting plate 10 to move outward, so that the mounting plate 10 pushes the locking block 8 through the connecting block 6 and engages with the inside of the groove 7.

[0028] Example 3: Based on Example 2, to improve the placement stability of the rotating rod 13, two slots 19 are provided inside the right side of the insulation ring 3. The rotating rod 13 is rotatably connected inside the insulation ring 3, which provides installation space for the rotating rod 13. Two sliding grooves 14 are provided inside the right side of the rotating rod 13. An elastic element 2 15 is fixedly connected to the inner wall of the sliding groove 14, and a pressing block 16 is fixedly connected to the other end of the elastic element 2 15. The pressing block 16 is slidably connected inside the sliding groove 14, and the sliding groove 14 supports the pressing block. 16 acts as a limit, allowing the pressing block 16 to slide smoothly. The end of the pressing block 16 away from the elastic element 15 is fixedly connected to the insert block 17. The right side of the pressing block 16 is fixedly connected to the pull block 18. The pull block 18 is slidably connected inside the slide groove 14. The slide groove 14 limits the pull block 18, allowing it to slide smoothly. One end of the insert block 17 engages with the inside of the slot 19, and the other end of the insert block 17 is slidably connected inside the slide groove 14, allowing the insert block 17 to limit the rotating rod 13.

[0029] When the rotating rod 13 needs to be rotated, by moving the two pull blocks 18 to a similar side, the pull blocks 18 can drive the pressing block 16 to move inward, thereby causing the pressing block 16 to compress the elastic element 15 and deform it, and causing the insert block 17 to slide into the interior of the slide groove 14, so that the insert block 17 can disengage from the interior of the slot 19, thereby rotating the rotating rod 13. After rotation, by releasing the pull blocks 18, the elastic element 15 can perform a reset movement, thereby causing the elastic element 15 to push the pressing block 16 to move outward, so that the pressing block 16 can push the insert block 17 to engage with the interior of the slot 19, thereby limiting the rotating rod 13.

[0030] The working process of this utility model is as follows:

[0031] When the insulation ring 3 needs to be installed, by moving the two pull blocks 18 to a closer side, the pull blocks 18 drive the compression block 16 to move inward, thereby causing the compression block 16 to compress the elastic element 15 and deform it, and causing the insert block 17 to slide into the slide groove 14, so that the insert block 17 can disengage from the slot 19. Then, the rotating rod 13 can be rotated, so that the rotating rod 13 can wrap one end of the pull rope 11, so that the other end of the pull rope 11 can pull the mounting plate 10 to compress the elastic element 12 and deform it, thereby causing the mounting plate 10 to pull the locking block 8 into the mounting groove 9. Then, the insulation ring 3 is placed inside the placement groove 2, so that the limiting block 4 can be inserted into the placement groove 2. Then, the two ends of the insulation ring 3 are fitted together, so that... Connecting block 6 slides into the interior of connecting groove 5. At this time, by releasing rotating rod 13, elastic element 12 is reset, which pushes mounting plate 10 outward, allowing mounting plate 10 to push locking block 8 through connecting block 6 and engaging with the interior of locking groove 7. Releasing pull block 18 allows elastic element 2 15 to reset, which pushes squeezing block 16 outward, allowing squeezing block 16 to push insert block 17 and engaging with the interior of slot 19. This limits rotating rod 13, allowing the insulation ring 3 to be easily installed and removed, thus protecting the water meter, greatly reducing the possibility of the water meter freezing, extending the service life of the water meter, and making it more economical to use.
