Today, I will introduce a national invention authorized patent-a self-generating device used in smart water meters. The patent was applied for by Shandong Guanxiang Technology Co., Ltd. and the authorization was announced on September 7, 2018.
Content descriptionThe invention belongs to the technical field of smart water meters, and particularly relates to a self-generating device applied to smart water meters.
Background of the inventionWater meters are installed in the water pipes at the entrance of the water supply network to measure water consumption. In order to facilitate the collection of water meter readings from the water terminal by the water supply unit, smart water meters have been adopted in the prior art. Smart water meters need power to operate. Some smart water meters are powered by batteries, and they need to be replaced manually after the power is exhausted. Sometimes the structural circuit of the water meter is still within the quality limit, but the battery power is exhausted. This is not only costly, consumes manpower and material resources, but also causes problems for users. inconvenient.
After retrieval, the announcement number 104006856A is a water meter with hydrodynamic self-power generation disinfection function, including a water meter base, a circular water surface cover, a water meter instrument panel device, a water flow generator module, a water inlet pipe and a water outlet pipe. A disinfection cavity is also installed at the outlet pipe of the water meter, and a disinfection device is arranged in the disinfection cavity, and the disinfection device is connected to the water flow generator module, wherein the water flow generator module is arranged on the water meter. The water inlet pipe includes a pipeline turbine generator propelled by tap water, a battery, a water flow sensing device and a main control device.
The self-powered smart water meter with the bulletin number 205349603U includes a smart water meter, a power generating device, and a regulating circuit. The power generating device is connected to the input end of the regulating circuit. The output terminal of the regulating circuit is connected to the smart water meter. The regulating circuit includes a rectifier. Circuits and capacitive devices.
In the above prior art, many aspects of the present invention may have been studied. However, the addition of a self-powering device that is easy to disassemble outside the body of the smart water meter has not been found in the prior art.
Summary of the inventionThe purpose of the present invention is to overcome the deficiencies in the prior art, and provide a self-generating device applied to the smart water meter that can be installed on the original smart water meter without replacing the pipeline and the smart water meter.
In order to achieve the above-mentioned objective, the technical solution adopted by the present invention is: a self-generating device applied to a smart water meter includes a metering module, a rectifier unit, a storage battery, a charging circuit, and a water turbine generator. The water turbine generator is installed in series. On one side of the smart water meter, a charging circuit is provided above the water turbine generator, a battery is connected to one side of the charging circuit, a rectifier unit is connected to one side of the battery, and a metering module is connected to one side of the rectifier unit. The storage battery, rectifier unit, and metering module are installed as a whole on one side of the smart water meter.
Preferably, the metering module, rectifier unit, battery, and charging circuit can be directly installed on the outside of the smart water meter and connected to the water turbine generator connected in series in the pipeline. Without the need for an external power supply, the smart water meter is not required. Intermittent power supply.
Preferably, the metering module, the rectifier unit, the storage battery and the periphery of the charging circuit are all provided with a waterproof coating to protect the circuit structure and prevent moisture from penetrating into the circuit and damaging the equipment.
Compared with the prior art, the present invention has the following beneficial effects: 1) It realizes the uninterrupted self-powering of the smart water meter without the need of an external power supply, and solves the current problem of the short service life of the smart water meter due to the battery;
2) Use the original tap water pipeline to realize the self-power generation of the equipment, without installing other energy devices, realize the secondary use of energy, energy saving and environmental protection;
3) There is no need to replace the battery house by house, avoiding the waste of manpower and material resources, and reducing the amount of engineering;
4) The original smart water meter can be equipped with a self-generating device, no need to replace the pipeline and the smart water meter, which is convenient and quick.
