Technical Field

[0001] This utility model belongs to the field of water meter technology, and more specifically, it relates to a water meter that prevents unauthorized tampering. Background Technology

[0002] Water meters are core equipment in water supply networks and crucial for water companies to settle water usage accounts with users and ensure water supply order. However, the anti-tampering design of mainstream water meters has certain flaws, making it difficult to curb illegal tampering. Most existing water meters use non-standard fasteners or lead seals for securing them, but these are exposed, allowing users to make their own disassembly tools or forge seals for unauthorized removal, thus failing to effectively prevent such activities.

[0003] Therefore, there is an urgent need for a water meter with a simple structure that is built into the water meter to prevent unauthorized tampering, so as to ensure the accuracy of pipeline metering and operational safety. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide an anti-tampering water meter. This meter utilizes a linkage-type water-blocking component and locking rod between the base and the housing to lock the base and housing during unauthorized tampering. Simultaneously, it can block the water outlet pipe, rendering the tampered water meter directly inoperable and preventing water flow. The meter must be returned to the factory for reset, forcing users to report the tampering, thus increasing the cost of unauthorized tampering and deterring such activities.

[0005] The aforementioned anti-tampering water meter includes a base and a housing, with the housing fixed to the top of the base. Inside the base, from bottom to top, are arranged a filter screen, a flow guide, an impeller, a base plate, and a meter body. An inlet pipe and an outlet pipe are fixed to both ends of the base, respectively. A water-blocking component is embedded within the base and extends and retracts along the bottom of the base. A first anti-tampering block and a second anti-tampering block are fixed to the outer wall of the base and the outer wall of the housing, respectively, and the first and second anti-tampering blocks are on the same straight line. Multiple locking rods are embedded within the first and second anti-tampering blocks, with one locking rod protruding into the base and abutting against the water-blocking component.

[0006] Preferably, the bottom of the base is provided with a groove, and its water-blocking component is embedded in the groove.

[0007] Preferably, the water-blocking component consists of a top spring and a baffle plate, which are sequentially embedded in the groove from the inside out, and the baffle plate extends and retracts toward the end of the water outlet pipe.

[0008] Preferably, the first anti-tamper block is provided with an adjacent first locking groove and a second locking groove, one end of the first locking groove is connected to the second anti-tamper block, and the other end is connected to the interior of the base.

[0009] Preferably, a first locking rod is embedded in the first locking groove, and one end of the first locking rod abuts against the barrier plate.

[0010] Preferably, the second anti-tamper block is provided with an adjacent third locking groove and a fourth locking groove, wherein the third locking groove is on the same straight line as the first locking groove; the fourth locking groove is located on the side of the third locking groove away from the second locking groove.

[0011] Preferably, a locking spring and a second locking rod are sequentially embedded in the third locking groove from top to bottom, and the second locking rod abuts against the first locking rod.

[0012] Preferably, when the first anti-tamper block and the second anti-tamper block are aligned, the first locking groove and the third locking groove are on the same straight line, and the first locking rod and the second locking rod abut against each other.

[0013] Preferably, when the first anti-tamper block and the second anti-tamper block are misaligned, the first locking groove is aligned with the fourth locking groove, and the second locking groove is aligned with the third locking groove. The top spring pushes the barrier plate and the first locking rod upward, so that while the barrier plate blocks the water outlet pipe, part of the first locking rod is embedded in the fourth locking groove; and part of the second locking rod is embedded in the second locking groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By installing an interlocking water-blocking component and locking rod between the base and the housing, the base and housing can be locked during illegal dismantling. Simultaneously, the water outlet pipe can be blocked, rendering the illegally dismantled water meter directly inoperable and requiring factory reset. This forces users to report the problem, increasing the cost of illegal dismantling and thus deterring such actions. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1 to 3 As shown, an anti-tampering water meter includes a base 1 and a housing 2, with the housing 2 fixed to the top of the base 1. Inside the base 1, from bottom to top, are arranged a filter screen 3, a flow guide shroud 31, an impeller 32, a base plate 33, and a meter body 34. An inlet pipe 11 and an outlet pipe 12 are fixed to both ends of the base 1, respectively. A water-blocking component 13 is embedded within the base 1, and the water-blocking component 13 extends and retracts along the bottom of the base 1. A first anti-tampering block 14 and a second anti-tampering block 21 are fixed to the outer wall of the base 1 and the outer wall of the housing 2, respectively, and the first anti-tampering block 14 and the second anti-tampering block 21 are on the same straight line. Multiple locking rods 16 are embedded within the first anti-tampering block 14 and the second anti-tampering block 21, and one of the locking rods 16 protrudes into the base 1 and abuts against the water-blocking component 13.

[0025] Optionally, connecting pieces 18 are fixed to the outer walls of both the base 1 and the housing 2. In this way, the base 1 and the connecting pieces 18 provided in the project are used to connect fasteners, such as bolts, lead seals, rivets, etc., to form a preliminary anti-disassembly structure.

[0026] Optionally, the base 1 is provided with a slot 17, which is adjacent to the edge of the end of the water outlet pipe 12 and located above the slot 17.

[0027] Optionally, a sealing gasket 10 is fixed between the base 1 and the housing 2.

[0028] Optionally, a sealing ring 331 and a sealing plate 332 are fixed between the substrate 33 and the body 34 in sequence.

[0029] Preferably, the bottom of the base 1 is provided with a groove 15, and the water-blocking component 13 is embedded in the groove 15. In this way, the movement path of the water-blocking component 13 can be limited by the groove 15, so that the water-blocking component 13 can always slide along the groove 15 and avoid deviation during the sliding process.

[0030] like Figure 3 As shown, the water-blocking assembly 13 consists of a top spring 131 and a baffle plate 132, which are sequentially embedded in the slide groove 15 from the inside out, with the baffle plate 132 extending and retracting towards the end of the water outlet pipe 12. Thus, the baffle plate 132 can be pushed out of the slide groove 15 under the elastic action of the top spring 131. When the baffle plate 132 is pushed out of the slide groove 15, its end is embedded in the slot 17, achieving the purpose of blocking the water outlet pipe 12 and preventing water from easily flowing out of the water outlet pipe 12.

[0031] like Figures 3 to 5 As shown, the first anti-dismantling block 14 is provided with an adjacent first locking groove 141 and a second locking groove 142. One end of the first locking groove 141 is connected to the second anti-dismantling block 21, and the other end is connected to the interior of the base 1.

[0032] like Figures 3 to 5 As shown, a first locking rod 161 is embedded in the first locking groove 141, and one end of the first locking rod 161 abuts against the barrier plate 132. Thus, under normal conditions, the first locking rod 161, by abutting against the barrier plate 132, prevents the barrier plate 132 from popping out. Conversely, when the water meter is tampered with, a gap appears in the second anti-tamper block 21, failing to effectively block the first locking rod 161. At this time, under the elastic action of the top spring 131, the barrier plate 132 and the first locking rod 161 move synchronously. While the barrier plate 132 blocks the water outlet pipe 12, part of the first locking rod 161 embeds into the second anti-tamper block 21, achieving the purpose of locking the base 1 and the housing 2, further improving the ability to prevent tampering.

[0033] like Figures 3 to 5As shown, the second anti-tamper block 21 has adjacent third locking grooves 211 and fourth locking grooves 212. The third locking groove 211 is on the same straight line as the first locking groove 141; the fourth locking groove 212 is located on the side of the third locking groove 211 away from the second locking groove 142. Thus, when the water meter is in normal operation, the first anti-tamper block 14 and the second anti-tamper block 21 are aligned, and the first locking groove 141 and the third locking groove 211 are on the same straight line. When the water meter is tampered with, the housing 2 rotates towards the base 1, causing the first anti-tamper block 14 and the second anti-tamper block 21 to misalign, and the third locking groove 211 moves towards the second locking groove 142. When the third locking groove 211 and the second locking groove 142 are on the same straight line, the first locking groove 141 and the fourth locking groove 212 are also on the same straight line, and part of the locking rod 16 is embedded in the fourth locking groove 212, preventing the housing 2 from continuing to rotate, thus achieving the purpose of preventing unauthorized disassembly.

[0034] like Figures 3 to 5 As shown, the third locking groove 211 contains, from top to bottom, a locking spring 163 and a second locking rod 162, with the second locking rod 162 abutting against the first locking rod 161. Thus, the second locking rod 162 and the locking spring 163 work together to fill the third locking groove 211 when the water meter is in its normal state (i.e., when the first locking groove 141 and the third locking groove 211 are aligned), preventing the first locking rod 161 from embedding into the housing 2. When the water meter is tampered with, the third locking groove 211 causes the second locking rod 162 and the locking spring 163 to move synchronously. When the third locking groove 211 and the second locking groove 142 are aligned, the locking spring 163, relying on its elasticity, pushes the second locking rod 162 out, causing part of the second locking rod 162 to embed into the second locking groove 142, thereby preventing the housing 2 from continuing to rotate. The second locking rod 162 works in conjunction with the first locking rod 161 to effectively improve the water meter's ability to prevent unauthorized tampering.

[0035] like Figures 3 to 5 As shown, when the first anti-tamper block 14 and the second anti-tamper block 21 are aligned, the first locking groove 141 and the third locking groove 211 are on the same straight line, and the first locking rod 161 and the second locking rod 162 abut against each other.

[0036] like Figures 3 to 5 As shown, when the first anti-tamper block 14 and the second anti-tamper block 21 are misaligned, the first locking groove 141 aligns with the fourth locking groove 212, and the second locking groove 142 aligns with the third locking groove 211. The top spring 131 pushes the barrier plate 132 and the first locking rod 161 upward, so that while the barrier plate 132 blocks the water outlet pipe 12, part of the first locking rod 161 is embedded in the fourth locking groove 212; and part of the second locking rod 162 is embedded in the second locking groove 142.

[0037] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
