split water meter

Abstract

The invention relates to the field of water meters, in particular to a split-type water meter. The split-type water meter comprises a base meter, a steel cover, a split meter shell, a fixing device, ameter-shell overturning cover, a connecting assembly, a PCB and a waterproof battery pack. The split meter shell comprises an upper shell and a lower shell, the PCB is installed in a circuit cabin, the waterproof battery pack is installed in a battery cabin, the waterproof battery pack is electrically connected with the PCB, and the PCB is an integrated PCB; the fixing device comprises bolt assemblies and a gear ring assembly, the bolt assemblies comprise bolts and screw blocks, stepped holes are formed in the lower shell, the bolts are in threaded connection with the screw blocks, the upperend faces of the screw blocks abut against the lower end face of the steel cover, and the gear ring assembly comprises an inner gear ring and an outer gear ring. According to the split-type water meter, a special design of the integrated PCB and the waterproof battery pack is adopted inside the split meter shell, the production cost is reduced, and disassembling, assembling and maintaining are more convenient and faster; meanwhile, a lower cover of the water meter is not required, the product area is reduced, and the product structure is simplified.

Problems solved by technology

[0002] Water meters are commonly used water flow measurement devices. At present, the existing split water meters adopt a split PCB circuit board structure, that is, the communication module circuit and the metering module of the water meter are separately designed into independent circuit boards. Not only caused the inconvenience of water meter installation, but also greatly increased the production cost of the water meter

In addition, in the existing split-type water meters, the battery part is directly designed on the PCB board. Since the use of the water meter is not easy to achieve waterproof and insulation, it is very easy to cause the battery leakage short circuit or circuit breaker due to water ingress in the water meter. board damage, etc.

At the same time, in the existing split water meters, the flip structure of the water meter is a snap-in or one-way rotating shaft type, and the snap-in flip structure is easy to fall

The one-way rotating shaft flip structure can only be rotated and opened in one direction, which not only results in limited operating space on the dial, but also when the space above the dial is small, the cover cannot be opened for reading

In addition, the clamshell structure of the one-way rotating shaft type requires a pin as the rotating shaft, which is not only cumbersome to assemble, but also increases the cost, and it is also troublesome to replace when the clamshell is damaged.

In addition, in the existing split-type water meters, the fixing method of the split-type case and the base meter is to use the lower cover fixed on the base meter to connect with the split-type case through bolts or buckles, which not only requires an additional The lower cover increases the cost, and increases the volume and installation time of the product
