A tamper-proof wireless remote water meter

Abstract

This utility model provides a tamper-proof wireless remote water meter, including a water meter body, both ends of which are connected to pipelines. The key feature is that at least one of the two connection points between the water meter body and the pipeline is equipped with an tamper-proof component. Each tamper-proof component contains a contact switch assembly, which includes a contact switch electrically connected to a circuit board within the water meter body via a wire. The circuit board contains a remote transmission module. By incorporating tamper-proof components at the connection points between the water meter body and the pipeline, and utilizing the contact switch assembly within these components, when someone attempts to tamper with the tamper-proof component and separate the water meter body from the pipeline, the contact switch is triggered, and the remote transmission module on the circuit board within the water meter body emits an alarm signal, alerting water management personnel to investigate.

Description

Technical Field

[0001] This utility model relates to the field of anti-tampering water meters, and in particular to an anti-tampering wireless remote water meter. Background Technology

[0002] With the increasing prevalence of smart water meters, water management departments across the country have gradually phased out the practice of sending meter readers door-to-door to read water usage data, bringing convenience to water management. However, in actual use, it has been discovered and reported that a small number of users are dismantling water meters to reduce water bills or sell copper water meters. To further meet user needs and reduce losses for water management departments, it is necessary to install tamper-proof structures for wireless remote water meters. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Please see Figures 1 to 4 As shown, a tamper-proof wireless remote water meter includes a water meter body 1, both ends of which are connected to a pipe 2. At least one of the two connection points between the water meter body 1 and the pipe 2 is provided with an tamper-proof component 3. Specifically, the tamper-proof component 3 is provided with a contact switch component 33, which includes a contact switch. The contact switch is electrically connected to a circuit board inside the water meter body 1 through a wire 4. The circuit board is provided with a remote transmission module.

[0032] In the above scheme, an anti-tampering component 3 is installed at the connection between the water meter body 1 and the pipeline 2. When someone damages the anti-tampering component 3 and tries to separate the water meter body 1 from the pipeline 2, the contact switch is triggered, and the remote transmission module on the circuit board inside the water meter body 1 will issue an alarm signal to prompt water personnel to check.

[0033] Understandably, to warn unauthorized disassembly, the circuit board is equipped with a buzzer that will emit a sharp alarm sound when the water meter is removed.

[0034] It is worth mentioning that the anti-tampering component 3 also includes a lower protective cover 31 and an upper protective cover 32, which together cover the connection between the water meter body 1 and the pipeline 2, as well as the contact switch assembly 33. The lower protective cover 31 or the upper protective cover 32 abuts against the contact switch of the contact switch assembly 33. Through the design of the lower protective cover 31 and the upper protective cover 32, the contact switch assembly 33 is protected on the one hand, and the contact switch is opened on the other. Specifically, if it is desired to separate the water meter body 1 from the pipeline 2, the lower protective cover 31 and the upper protective cover 32 need to be removed. At this time, the lower protective cover 31 or the upper protective cover 32 no longer abuts against the contact switch of the contact switch assembly 33, and then the remote transmission module on the circuit board inside the water meter body 1 will issue an alarm signal to alert water management personnel.

[0035] Preferably, the lower protective cover 31 and the upper protective cover 32 are connected by screws 34, and the top of the screws 34 is provided with anti-disassembly plugs 35 to prevent the lower protective cover 31 and the upper protective cover 32 from being disassembled.

[0036] It should be noted that the lower protective cover 31 is provided with an installation groove that is compatible with the contact switch assembly 33, and the lower protective cover 31 is connected to the water meter body 1 by a buckle or a slot, thereby improving the stability of the anti-tamper assembly 3.

[0037] It should be added that, such as Figure 4 The contact switch assembly 33 includes a housing and a flexible cover. The flexible cover is located on top of the housing, and the two form a sealed space. The contact switch is located within this sealed space, thereby protecting the contact switch from damage caused by a humid environment. Similarly, sealant is provided at the connection between the contact switch assembly 33 and the wire, further enhancing its waterproof and moisture-proof capabilities.

[0038] It is worth mentioning that the anti-tampering component 3 is preferably installed at the water inlet end of the water meter body 1 to prevent criminals from causing the water flow to bypass the water meter.

[0039] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
