Today, I will introduce a national invention authorized patent-multifunctional smart water meter. The patent was applied for by Guangzhou Zhaoji Instrument Manufacturing Co., Ltd., and the authorization was announced on May 24, 2017.
Content descriptionThe utility model relates to the field of water meters, in particular to a multifunctional intelligent water meter.
Background of the inventionAt present, there are various water meters in the society, and smart water meters are high-tech products developed in recent years with the support of automatic control technology and information network technology and relying on the needs of information management. However, the current water field is due to water pipes. The aging of the network and the destruction of external forces, or the destruction of the water device connected to the pipeline, and the forgetting to turn off the water valve, etc., are common. However, the general water meter only has a metering function and does not have a leak-proof detection function.
Summary of the inventionIn order to overcome the above shortcomings of the prior art, the purpose of the present utility model is to provide a simple, environmentally friendly, multifunctional intelligent water meter with leak detection function.
The technical solution adopted by the utility model to solve its technical problems is: a multifunctional intelligent water meter, including a water meter housing; wherein: the upper cover of the water meter housing has an intelligent digital display at one end, and a base dial protection cover at the other end, There is a character wheel in the protective cover of the base meter dial; the water meter has a controller inside, and the controller is connected with the intelligent digital display screen, power supply module, transformer, leak detection module and wireless module The anti-control controller is also provided with a controller guard, the water meter outlet is equipped with a solenoid valve and a temperature sensor; the temperature sensor is connected to the controller.
The working principle of the present invention is that when water flows through the water meter, the word wheel is driven to rotate to record the water consumption, the water flows to the outlet of the water meter, the temperature sensor detects the temperature of the water, and the water consumption and temperature are sent to the intelligent digital display screen through the controller The leak detection module has a pressure sensor, an initialization unit and a blocking mechanism; the pressure sensor and blocking mechanism are respectively connected to the alarm module; the pressure sensor is installed at the lower end of the water meter and connected to the initialization unit; when in use, it is in the initialization unit Set the time for the pressure sensor to continuously collect data. Once the time is reached, the alarm module will be activated to give an alarm. When water flows through the water meter, the pressure sensor will start timing under the action of water gravity. If the user forgets to turn off the water or the water pipe is leaking, the water meter’s There is continuous water flow on the gravity sensor. Once the initial setting time is exceeded, an alarm will remind the user to check; the blocking mechanism has a button and a reset spring. Once someone needs to use water for a long time, you only need to press the resistance on the water meter. Disconnect the button in the mechanism and disconnect the gravity sensor from the alarm module; when the reset spring pops up the button, the gravity sensor and the alarm module are reconnected to start leak detection.
As a further improvement of the present invention: the leak detection module has a pressure sensor, an initialization unit and a blocking mechanism; the pressure sensor and the blocking mechanism are respectively connected to the alarm module; the pressure sensor is installed at the lower end of the water meter And connected with the initialization unit. The alarm module is a buzzer, a strobe light or a combination of the two. The power module is a button lithium battery. The protective cover of the base dial is made of toughened glass. The wireless module is connected to the mobile terminal via wifi or bluetooth. The mobile terminal is a smart phone or a computer.
Compared with the prior art, the beneficial effects of the utility model are: the utility model has the functions of measuring water consumption, water temperature and leak detection; the leak detection function can effectively reduce the waste of water resources and adopts the principle of gravity sensing of water itself. , Energy saving and convenient.
