Description

Technical Field

[0001] The present invention relates to the technical field of water meters, and in particular to a universal case of a remote water meter and a remote water meter. Background Art

[0002] Most valveless remote water meters on the market are composed of a base meter, electronic parts, plastic structural parts and other auxiliary parts. The base meter is divided into photoelectric, pulse and non-magnetic signaling methods. At present, the modular design of water meters is becoming more and more popular in the market, and the modular development of water meters has become a market trend. In the existing valveless modular remote water meters, modularization can often only take into account one type of base meter signaling method, and cannot be universally compatible with base meters of multiple signaling types. For example, the modular structure of valveless and non-magnetic remote water meters cannot be applied to valveless photoelectric remote water meters and valveless pulse remote water meters.

[0003] Traditionally, a Chinese patent (CN201720305539.7) discloses a modular smart water meter, including a valve-controlled case assembly, a module assembly and an electric actuator assembly, wherein the module assembly is detachably connected to the electric actuator assembly, and the electric actuator assembly is detachably connected to the valve-controlled case assembly. The patent modularizes the valve-controlled case assembly, module assembly and electric actuator assembly of the water meter, and each module adopts a detachable structure, so that the connection, installation and disassembly between the modules are convenient, simplifying the installation and disassembly work of the workers. However, the patent only discloses that the modular connection, installation and disassembly between the components are convenient, achieving a certain degree of universality, but it cannot be universal for water meters with different signal transmission methods, which will lead to increased mold costs, an increase in the number of materials, an increase in inventory types, etc., which will increase the overall cost of the water meter.

[0004] Therefore, there is an urgent need for a universal housing for remote water meters that can take into account different signal transmission methods and effectively reduce material and production costs. Summary of the invention

[0012] As a further improvement of the above scheme, the positioning clamp includes a transverse connecting plate and a vertical connecting plate, which are connected in sequence in a T shape, and the transverse connecting plate is provided with a threaded hole. Correspondingly, the outer cover of the meter is provided with a through hole matching the threaded hole of the transverse connecting plate; the vertical connecting plate is provided with a through hole connected to the lead sealing hole of the lead sealing rib.
