Description
Technical Field
[0001] The utility model relates to the technical field of intelligent water meter applications, in particular to an intelligent control water meter shell commonly used for dry and wet base meters. Background Art
[0002] A water meter is an instrument that measures water flow, most often cumulative flow. It is generally categorized as either a volumetric or velocity type. The internal structure of a traditional water meter consists of three main components, from the outside inward: the housing, the sleeve, and the inner core. The housing is made of cast iron. After entering the water inlet, water passes through the lower annular space in the housing, called the "lower annular chamber." Above this annular space is the "upper annular chamber," which connects to the outlet. A filter with small holes is located at the bottom of the sleeve to filter out impurities. The sleeve has two rows of circular holes on its side, aligned with the upper and lower annular chambers of the housing. The lower row is the water inlet, and the upper row is the water outlet. The inner core is divided into three layers: upper, middle, and lower. The upper layer houses the pointer and dial, while the lower layer houses the impeller. The impeller is positioned within the rotating flow generated by the holes in the lower layer of the sleeve. The water impacts the blades around the impeller, generating torque that rotates the impeller, and this rotation measures the water flow.
[0003] Water meters are categorized by their water immersion status—that is, whether the counter is immersed in water—as wet, dry, and liquid-sealed. A wet water meter is one whose counter is immersed in water. The meter's surface is subject to water pressure, and the sensor and counter are driven by a gear mechanism. Over time, the quality of the water can affect the clarity of the meter readings. A dry water meter is one whose counter is not immersed in water. Structurally, the sensor and counter chamber are isolated, and the meter glass is not subject to water pressure. The sensor and counter are typically driven by magnets. A liquid-sealed water meter is one in which the meter reading dial or the entire counter is sealed with a liquid such as glycerin at a certain concentration. The clarity within the sealed, isolated counter is unaffected by external water quality. The remaining structural properties are the same as those of a wet water meter.
[0004] With the continuous advancement of technology, water meters have evolved from their original purely mechanical structure to include intelligent control technology. This has enabled more sophisticated and convenient functions such as flow measurement and meter reading. Smart water meters build upon the basic mechanical structure of a water meter by adding an intelligent control housing with built-in control devices to achieve intelligent control of the meter. However, due to the different structural designs of dry and wet water meters, the intelligent control housings used are also different, making them incompatible. Furthermore, water meters also have different power consumption and battery capacities, making them incompatible. Furthermore, there are also attempts to vandalize smart water meters during use. For example, attempts to dismantle the meter's control box or power supply in an attempt to disable meter operation and reduce water bills are common. This creates significant difficulties in meter maintenance, repair, and replacement, making it crucial for water meters to be tamper-resistant and vandal-resistant. Summary of the Invention

[0015] In this embodiment, although the water meter base 1 and the control box 3 are placed together through the connecting shell 2, they are essentially separated in structure. This design facilitates the repair and maintenance of the water meter base 1 and the control box 3. If abnormal electromechanical separation occurs, the control program loaded on the intelligent control circuit board in the control box 3 will also issue a warning to the system, reminding the management department to verify.
[0016] As a preferred embodiment, in this embodiment, the shape of the flip cover 21 on the top of the connecting housing 2 is adapted to the shape of the groove on the top of the control box 3 to form a seamless connection.
