Today, I will introduce a national invention authorized patent-a modular structure of a smart water meter. The patent was applied for by Shanghai Jieliang Electronic Technology Co., Ltd., and the authorization was announced on August 21, 2018.
Content descriptionThe utility model belongs to the technical field of water meters, and particularly relates to a modular structure of an intelligent water meter.
Background of the inventionIn order to solve the moisture problem, the existing smart water meters in the market all adopt glue filling treatment, which has the following technical defects: 1) After the smart water meter has been used for a certain number of years, the glue is aging and cannot reach the moisture-proof effect, causing the electronic part of the smart water meter to fail; 2 ). The quality of the glue used to fill the glue is not good enough, and it will absorb water, causing the electronic part of the smart water meter to fail prematurely; 3) The electronic part of the smart water meter cannot be repaired and can only be scrapped, and the subsequent maintenance cost is high.
Summary of the inventionThe purpose of this utility model is to solve the above technical problems.

The purpose of the utility model is realized as follows: a modular structure of a smart water meter, including a module body, characterized in that: the module body is composed of a bottom shell and a cover plate, and the bottom shell is composed of an arched door frame body without a cover The structure is combined with an uncovered rectangular frame structure. The center of the bottom plate of the arched door frame structure is provided with a through hole A. The bottom of the smart water meter passes through the through hole A to connect with the water inlet pipe; the center of the bottom plate of the rectangular frame structure is provided with a through hole. Hole B, through hole B is provided with a rubber bushing, a ball valve is arranged in the rubber bushing to connect with the water inlet pipe below; a lithium battery box is arranged in front of the rear side plate of the rectangular frame structure, and the lithium battery box is formed by several It is composed of supporting pieces A arranged equidistantly in the left and right directions; on the inner walls of the other three sides of the rectangular frame structure except the rear side plate, there are several supporting pieces B arranged equidistantly, and the control module housing is arranged above the supporting pieces B, The control module housing is provided with a circuit board and a driving mechanism; the control module housing is composed of an upper cover and a lower cover. The lower cover is a square frame structure without a cover. The bottom of the lower cover is provided with a through hole C, The outer ring of the hole C is provided with an annular boss, and the driving mechanism passes through the through hole C and is connected to the top surface of the ball valve.
The top center of the supporting sheet A is provided with a concave arc. The front side plate of the upper cover body is provided with a plurality of contacts arranged equidistantly along the left and right directions. The upper cover body and the lower cover body are snap-fit ​​and sealed structures.
The utility model has reasonable structural design, does not require glue treatment, has a waterproof level of IP67, simple production and manufacturing, time saving, convenient after-sales maintenance, lower maintenance costs in the later period, and good economic and social benefits for popularization and application.
Electric Vehicle Battery Supply
Lithium-Ion Batteries
Lithium-ion batteries are currently used in most portable consumer electronics such as cell phones and laptops because of their high energy per unit mass relative to other electrical energy storage systems. They also have a high power-to-weight ratio, high energy efficiency, good high-temperature performance, and low self-discharge. Most components of lithium-ion batteries can be recycled, but the cost of material recovery remains a challenge for the industry. The U.S. Department of Energy is also supporting the Lithium-Ion Battery Recycling Prize to identify solutions for collecting, sorting, storing, and transporting spent and discarded lithium-ion batteries for eventual recycling and materials recovery. Most of today's PHEVs and EVs use lithium-ion batteries, though the exact chemistry often varies from that of consumer electronics batteries. Research and development are ongoing to reduce their relatively high cost, extend their useful life, and address safety concerns in regard to overheating.
