Description

Technical Field

[0001] This utility model relates to the field of valve-controlled water meter technology, and in particular to a dry valve-controlled water meter. Background Technology

[0002] In some parts of my country, water meters are often installed centrally in pipe wells during urban infrastructure planning, resulting in them operating in damp, low-lying environments for extended periods. Especially during the rainy season, they are frequently submerged in water. Therefore, ensuring the long-term stable operation of smart water meters in such environments is crucial for protecting their electronic components from moisture. However, current valve-controlled water meters still have certain deficiencies in terms of sealing and moisture protection, resulting in less than ideal protection. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the existing technology and provide a dry valve-controlled water meter.

[0004] The objective of this utility model can be achieved through the following technical solutions:

The cover presses down on the top of the copper seal module assembly and is fixed to the valve-controlled base meter. The copper seal module assembly is fixedly assembled to the valve-controlled base meter. The gearbox is completely covered by the cover. The copper seal module assembly includes a copper seal cover and tempered glass fixed to the copper seal cover. A sealing ring is provided between the copper seal cover and the tempered glass. A counter is installed inside the copper seal cover.

[0006] Furthermore, the counter includes a lower clamping plate and an upper clamping plate; the lower clamping plate is provided with a battery compartment and a motor slot; a micro motor is installed in the motor slot; a battery for providing power to the micro motor is installed in the battery compartment; a counter gear set is provided on the upper clamping plate; a clamping plate positioning post is also provided on the upper clamping plate; the lower clamping plate is provided with a clamping plate positioning hole that matches the clamping plate positioning post; the lower clamping plate and the upper clamping plate are fixed together by the clamping plate positioning post and the clamping plate positioning hole.

[0008] Furthermore, the micro motor is locked to the lower clamping plate by a motor clip; an upper magnet is provided at the bottom of the micro motor.

[0009] Furthermore, the gearbox includes a lower gearbox housing and a cover plate; the cover plate is fixed to the lower gearbox housing by cover plate screws; the lower gearbox housing has multiple shaft holes, in which gear shafts are installed, and gear sets are fitted on the gear shafts; the lower gearbox housing also has sector teeth that mesh with the gear sets; the bottom of the sector teeth is connected to a linkage valve stem that passes through the lower gearbox housing; and a valve stem sealing ring is provided on the linkage valve stem.

[0010] Furthermore, a transmission magnet bracket is also provided inside the lower gearbox; the transmission magnet bracket is meshed with the gear set, and a lower magnet is provided on the top for use with the upper magnet; the lower magnet is positioned directly opposite the bottom of the micro motor above.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] (1) This utility model uses a cover to press the top of the copper seal module assembly to fix the copper seal module assembly onto the valve control base gauge. After rolling, the copper seal cover of the copper seal module assembly forms a sealed cavity with the sealing ring and tempered glass, which can effectively protect the internal battery, micro motor and circuit board and other components from being affected by water and moisture to work normally. At the same time, the tempered glass will not fog up and obstruct the view when the counter is reading. It has a good sealing and moisture-proof effect, long service life and stable operation.

[0015] (2) The micro motor of this utility model is directly downward, and does not require bevel gear reversal. It can be driven by directly meshing with the gear. This structural design allows the copper cover to be stamped directly without side welding, which simplifies the structure and reduces costs. Attached Figure Description
