[Instrument latest patent] é“‹ brass lead-free smart meter

[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduced a national invention-issued patent - Bengbu brass lead-free smart water meter. The patent was applied for by Shanghai Tianshen Copper Group Lead-free Smart Meter Co., Ltd., and it was authorized on April 3, 2018.

Content Description

The invention relates to the technical field of water meter equipment, in particular to a brass-free lead-free smart water meter.

Background of the invention

Lead brass has excellent mechanical properties and physical properties as well as good casting performance and cutting performance, as well as low cost, and is therefore widely used in instrumentation, electronics, appliances, household hardware, drinking water systems, etc., especially in Hpb59-1. The production and application of the largest amount, but lead and its compounds are 17 kinds of chemical substances that seriously endanger human life and the natural environment, lead in the alloy in the alloy can easily invade or emerge from the matrix, industrial waste products The lead infiltrates into the groundwater system. Various forms of lead enter the animal or human food chain through various ways, endanger human health and affect the environment. In recent years, medical experts around the world have discovered that lead-containing copper alloys constitute human health and environmental sanitation. As a threat, medical institutions such as the European Union, the United States, Japan, and China have all made reports that lead-containing copper alloys are harmful to the human environment. Given the harm of lead to the human health environment, the United States, Japan, and European Union countries have successively issued Governmental restrictions on the application of lead-containing copper alloys, the Chinese government has also issued "electronic information products" consistent with international restrictions. Pollution prevention and control measures and other compulsory regulations, the lead content in copper alloys (in which the content of lead in electronic information products must be less than 0.1%) and the amount of lead leaching in drinking water (Japan must be less than 0.01mg/L, the United States must Less than 0.0011%, respectively, has made strict control of the order, and will continue to reduce the lead content, the application of lead-containing copper alloys are facing strict restrictions and challenges, and the outlook will become more and more serious, so the development of lead-free brass Lead-brass and lead-free bronze, which are used in place of taps and water meters in drinking water systems, have become major issues facing the metal materials industry today, and are also important tasks in responding to the requirements of the world's circular economy (EHS program).

Most of the water meters currently in use need to be powered by batteries. After a period of time, the batteries need to be replaced. This is troublesome. At the same time, the material of the water meter may affect human health. Therefore, a brass-free leadless smart water meter is proposed.

Summary of the Invention

In order to solve the above problems, the present invention provides a brass-free lead-free smart water meter.

The figure is a schematic structural view of the invention

In order to achieve the above objectives, the present invention provides the following technical solutions: é“‹ Brass lead-free smart water meter, including the outlet pipe connection, drum, blade, battery, water meter housing, cover, cover, photoelectric water meter core, inlet pipe interface, Rear cover, power generation device, power generating box, negative magnet, bearing, rotating shaft, positive magnet and coil, cover of the water meter cover is provided above the cover of the meter, the cover of the watch cover is provided below the cover, and the cover is located inside the water meter cover. At the bottom, there is a photoelectric water meter movement. The bottom of the water meter housing is equipped with a back cover. The water meter housing is equipped with a water inlet connector on one side, and the water outlet connector is on the other side of the water meter housing. The groove is provided with a rotating cylinder inside the groove. The rotating cylinder has a cylindrical structure. One end of the rotating cylinder is connected with the side of the cylindrical groove above the inner wall of the outlet pipe connection. The other end of the rotating shaft extends through the side of the cylindrical groove. To the outer surface of the outlet pipe connection, the rotating drum is provided with blades, the number of blades is evenly distributed in one cycle of the rotating drum, the power generating device is arranged on the side of the outlet pipe connection, and the outlet pipe is above the interface There is a battery, and the power generation device includes a generator box, a negative magnet, a bearing, a shaft, a positive magnet and a coil. The generator box is welded on the side of the outlet pipe connector. The generator shaft is provided with a shaft in the middle of the outlet. One end of the shaft protrudes from the drum. One end of the outer surface of the outlet pipe connection is welded, and the other end of the shaft is sleeved with a bearing. The shaft is fixedly connected to the side of the generator box. The shaft is provided with a coil. Negative and positive magnets are respectively provided on both sides of the shaft, and the coil and the negative magnet are provided. Parallel to the positive magnet, the coil is electrically connected with the battery, and the battery is electrically connected with the photoelectric water meter core.

The water meter housing is made of lanthanum brass and lead-free alloy material, which prevents the lead element in water from affecting people's health. At the same time, the chemical properties of the material are stable and the service life is improved. There is a sealing ring at the interface of the inlet pipe to prevent water leakage at the interface and waste water resources. A rubber sealing ring is arranged at the joint of the rotating tube through the outlet pipe interface to prevent the water in the water pipe from leaking from the interface, so that the rotating drum can drive the rotating shaft to rotate. The blades have a rectangular structure and are made of stainless steel alloy. The materials do not contain harmful elements to the human body and ensure the health of the human body. At the same time, the materials are inexpensive and reduce the manufacturing cost.

Compared with the prior art, the beneficial effects of the present invention are: the design innovation of the present invention adopts a water meter housing made of antimony brass lead-free alloy material, effectively avoiding the harm of heavy metal elements to the human body, and the present invention solves the market Some water meters need to replace the battery problem, the device is equipped with a battery, the power generated by the water flow storage for the use of optical water meter movement, reducing the work intensity of the staff, user-friendly use.
