Background art under the promotion of the factors of the water resource shortage form and the internet of things information era in China, the opportunity of large-scale updating and upgrading of the water meter manufacturing industry in China comes, especially along with the continuous development of rural drinking water safety quality improvement and efficiency improvement engineering and rural drinking water urbanization engineering in all parts of the country, the demands of the internet of things and the prepayment valve control water meter in rural areas are increased day by day, but the traditional prepayment valve control IC card intelligent water meter in China at present cannot be well adapted to the use needs of the rural areas, and is mainly reflected in the following aspects:
rural water meter well temperature changes greatly. Because most of rural meter wells are arranged outdoors, especially in northern areas of China, the changes of the environmental temperature in the meter wells are obvious in four seasons.
The rural water meter well has large humidity change. Because the rural water meter well is positioned outdoors, the water meter well has accumulated water due to high underground water level in partial areas, rural rainwater surface runoff and the like under the repeated change of the environmental temperature. The humidity in the well is high in most of the whole year, the water meter is just in a sauna room, and moisture can not enter the sauna room, so that the electromechanical components of the water meter are corroded due to the moisture entering the sauna room, and the circuit part is short-circuited, so that the damage rate is high.
The dry and wet environment of the rural water meter well changes frequently. The water meter well in the rural area is sometimes water, sometimes damp, sometimes dry and cold and sometimes frozen due to the reasons that the water meter well is outdoors, the underground water level rises in spring, the surface runoff is merged in rainy season in summer and autumn, the snow is melted in winter, and the artificial drainage caused by no centralized drainage is merged in the water meter well, so that the working environment of the water meter is changed greatly, and the domestic existing waterproof water meters cannot be completely adapted to the repeated huge environmental change, so that the water meter is damaged by water inflow, metal components are corroded, a circuit board is short-circuited and the like.
The accumulation of sludge in the rural water meter well causes saline-alkali corrosion damage. A large amount of silt flows into the water meter well when surface runoff is formed due to little hardening of the ground around the rural water meter well, after water is evaporated or seeps downwards, soil buries part or all of the water meter, and the water meter is damaged too early due to saline-alkaline corrosion because saline-alkaline exists in the soil.
The invention basically solves the problems and aims to provide a passive Internet of things IC card prepayment valve control intelligent moisture-proof water meter which is suitable for normal use in a rural water meter well in a severe environment. The invention keeps the use habit of the traditional IC card prepayment valve-controlled water meter user, and simultaneously, the mechanical reading of the water quantity is transmitted to a Hall receiving circuit sealed in an electronic cabin by utilizing Hall technology through a magnetic pulse signal, and the Hall receiving circuit is subjected to the calculation processing of a main control circuit board arranged in the electronic cabin so as to drive and control a motor actuator arranged in the electronic cabin to drive a magnetic transmission coupling driving device, and the driving device drives an external magnetic steel arranged on a ball valve rod outside the electronic cabin to transmit by utilizing the magnetic force of a magnetic field, thereby realizing the opening and closing of the ball valve; a breathing chamber is arranged in the electronic cabin, so that the electronic cabin actively expands and contracts along with the change of the ambient temperature, the air exchange between the electronic cabin and the atmosphere is avoided, and moisture and water are prevented from entering the electronic cabin;
the object of the present invention is achieved by the following technique; the water flow information acquisition system is characterized in that a magnetic pointer is arranged in a base meter, the magnetic pointer is driven to rotate by water flow, the upper part of the magnetic pointer is used as a part of a Hall sensing element and transmits an electromagnetic pulse signal generated by the rotation of the magnetic pointer to a Hall sensor in a non-contact mode, the information processing system analyzes and processes the water flow electromagnetic signal acquired by the Hall sensor and provides the analyzed and processed water flow electromagnetic signal to a valve control execution system circuit to open or close a valve control execution mechanism assembly, the information processing system is the existing mature technology in the market and does not belong to the technical appeal of the invention and is not further described, the valve control execution system comprises internal magnetic steel which is arranged in a closed independent electronic cabin and is connected by a valve control actuator assembly, the lower end of the inner magnetic steel is sealed and provided with an independent outer magnetic steel in an outer concave hole of the electronic cabin, the lower end of the outer magnetic steel is provided with a valve rod, the lower end of the valve rod is connected with a ball valve, the ball valve controls the opening and closing of water flow, a plastic shell is arranged between the inner magnetic steel and the outer magnetic steel in a spaced mode, the inner magnetic steel, the valve control execution mechanism assembly, the valve control execution system circuit and the Hall sensor are all wrapped in the plastic shell to form a sealed whole, and a breathing cabin made of corrugated plastic is further arranged in the plastic shell and used for adjusting the internal pressure of the plastic shell when the plastic shell is subjected to thermal expansion and cold contraction of the external environment, so that the normal work of electronic elements in the plastic shell is guaranteed.

When the inner magnetic steel rotates, the outer magnetic steel is influenced by the magnetic force of the inner magnetic steel to rotate along with the inner magnetic steel, so that the valve rod and the ball valve are driven to rotate, and the water flow is controlled to be opened and closed.
The upper cover and the lower cover of the water meter plastic shell are fused together into a sealed whole through a hot pressing technology, so that external moisture water drops are blocked outside the plastic shell, and electronic elements in the plastic shell are protected, so that the service life is prolonged.
Although the existing intelligent water meters can basically meet the water metering and settlement in building users, actuators and circuit boards in meter bodies are prematurely corroded and damaged due to the fact that moisture is contacted with most of the intelligent water meters due to the severe environment of meter wells, and along with the development of rural drinking water safety quality improvement and efficiency enhancement engineering and rural drinking water urbanization engineering, the existing intelligent water meters in the market cannot be normally used in the severe rural inspection well environment, therefore, the intelligent water meters overcome the defects of the existing electronic intelligent water meters in the aspects of water resistance and moisture resistance, the adaptability and the service life of products are improved, and the market demand is huge.
In summary, the technical gist of the present invention is not exclusive, and modifications made by those skilled in the art without substantial innovation are considered to be within the scope of the present disclosure.
