Today, I will introduce to you a national invention authorized patent-a smart water meter with a separate body. The patent was applied for by Lianyungang Water Meter Co., Ltd., and the authorization was announced on February 8, 2017.
Content descriptionThe utility model relates to a water metering device, in particular to an intelligent water meter hanging separately from the outside.
Background of the inventionThe existing smart water meters are all integrated. When installed and used in rural areas, the installation environment in rural areas is basically surface wells, and the well depths are basically between 1.5 meters and 2 meters. The existing smart water meters have the following shortcomings in actual use: 1. When installed and used in deep wells, the well is deep, it is not easy to check the meter readings, and it is inconvenient to swipe the card. 2. Used in deep wells, the working environment is poor, and it may be flooded. Some parts cannot be sealed separately, so the electronic components and battery connectors will be damaged and the work will be unstable. 3. The actuators and other parts of the integrated meter are sealed together with the control box as a whole, and cannot be replaced separately if damaged. It is not convenient for later installation and maintenance, and the workload is heavy.
Summary of the inventionThe technical problem to be solved by the utility model is to aim at the deficiencies of the prior art, and proposes an externally-mounted smart water meter which is convenient to install and use and is reliable.
The technical problem to be solved by the utility model is realized by the following technical solutions. A separate externally mounted smart water meter is characterized by: including a mechanical metering unit connected with the pipeline and an externally mounted intelligent control unit, a mechanical metering unit and an intelligent The control part is connected through the data line.
The mechanical metering unit includes a meter body and an on-off valve. The upper part of the on-off valve is provided with an actuator component that controls the opening and closing of the on-off valve. The actuator component is arranged in a closed box body. The closed box body includes a connection with the meter body. It is an integrated actuator base, and an actuator sealed box that is hermetically connected with the actuator base. The intelligent control unit includes a battery box. The battery box is provided with a sealed upper cover. The battery box contains a battery and a circuit board module. The cover is provided with a card swiping area and a liquid crystal display area. Corresponding to the swiping area and the liquid crystal display area, there are a swiping sensor module and a liquid crystal display module. The swiping sensor module and the liquid crystal display module are electrically connected to the circuit board module. The circuit board module of the intelligent control unit is connected, and the other end is connected with the actuator component of the mechanical metering unit.
The technical problem to be solved by the utility model can be further realized by the following technical schemes. O-ring mechanical sealing mechanisms are provided at the data line outlets of the actuator sealing box and the battery box. The data line is provided with a metal hose sheath. The bottom of the battery box of the intelligent control unit is provided with a screw hole for external hanging.
Compared with the prior art, the utility model adopts a split design for the mechanical metering part connected with the pipeline and the external intelligent control part, so that the actuator becomes an independent body. When a failure occurs, this part can be replaced as a whole, which is convenient for later installation Replacement maintenance. All modules of the control unit are encapsulated in the battery box. When there is a failure or damage, you only need to open the sealed box cover to replace the faulty or damaged parts, which is convenient for installation and replacement. In addition, the separate intelligent control unit has a higher external position, and the working environment is relatively better. The electronic components can be effectively protected and the work is more stable.
Anisotropic magnets are magnets whose magnetization directions in the magnets are aligned in a certain direction.
Magnet powder for anisotropic magnets is composed of a single crystal or polycrystal with an aligned direction of magnetization in one magnet particle. When a magnetic field is applied externally during molding (this magnetic field is called an aligning magnetic field), the magnet powder moves to align with the direction of the magnetic field and is solidified in an aligned state, resulting in an anisotropic magnet. Magnet powder aligned with an aligning magnetic field is solidified with keeping magnetization. Therefore, after removing the alignment magnetic field, the molded body becomes a magnet having a magnetic force.
