Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent water meters, in particular to an intelligent water meter without magnetic sampling. Background Art

[0002] A water meter is an instrument that measures water flow, usually the cumulative measured flow of water. It is generally divided into two types: volumetric water meters and velocity water meters. When selecting a water meter specification, you should first estimate the size and flow range of the flow rate usually used, and then select a water meter with a specification that is closest to the commonly used flow rate.

[0003] The smart water meter is equipped with a microelectronic structure, and the water consumption data is counted and transmitted through the internal electronic components when in use. The existing smart water meter uses water flow through magnets and spiral metal sheets to generate a rotating magnetic field, and then senses a pulse signal through a magnetic sensitive element, which is converted into the volume of water and transmitted to a pointer or digital display, thereby realizing the measurement of water consumption. However, this method is easily interfered by the magnetic field and is inconvenient to use. Summary of the invention

[0004] The utility model aims to provide an intelligent water meter without magnetic sampling, which can accurately judge the water flow rate passing through the main body of the intelligent water meter and is easy to use.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a smart water meter with non-magnetic sampling, including a smart water meter body, the top of the smart water meter body is fixedly connected to a shell, the smart water meter body is movably connected with a first rotating shaft, the top of the first rotating shaft is fixedly connected to a first gear, the first gear is located inside the shell, the inner bottom of the shell is movably connected with a second rotating shaft, the outer surface of the second rotating shaft is fixedly connected to the second gear, the side of the second gear is meshingly connected with the side of the first gear, the top of the second rotating shaft is fixedly connected to the first bevel gear, the inner side wall of the shell is movably connected to a third rotating shaft, the outer surface of the third rotating shaft is fixedly connected to the second bevel gear, the side of the second bevel gear is meshingly connected with the side of the first bevel gear, the side end of the third rotating shaft is fixedly connected to a metal rod, and an induction column is installed inside the shell.

Water flowing through the smart water meter body 1 will drive the blades 5 to move. The blades 5 are located inside the smart water meter body 1. The top of the first rotating shaft 4 is fixedly connected to a first gear 6. When the blade 5 moves, it will drive the first rotating shaft 4 to rotate, thereby driving the first gear 6 to rotate. The first gear 6 is located inside the shell 3, and the inner bottom of the shell 3 is movably connected to a second rotating shaft 7. The outer surface of the second rotating shaft 7 is fixedly connected to a second gear 8. The side of the second gear 8 is aligned with the first gear 6. 6 is meshed with the side of the first gear 6, the diameter of the second gear 8 is larger than the diameter of the first gear 6, when the first gear 6 rotates one circle, the second gear 8 rotates less than one circle, the first gear 6 rotates, thereby driving the second gear 8 to rotate, the top of the second rotating shaft 7 is fixedly connected with the first bevel gear 9, and when the second rotating shaft 7 rotates, it will drive the first bevel gear 9 to rotate, the inner side wall of the shell 3 is movably connected with the third rotating shaft 10, and the outer surface of the third rotating shaft 10 is fixedly connected with the second bevel gear 11, the side of the second bevel gear 11 is meshed with the side of the first bevel gear 9, when the first bevel gear 9 rotates, it drives the second bevel gear 11 to rotate, thereby driving the third rotating shaft 10 to rotate, the side end of the third rotating shaft 10 is fixedly connected with a metal rod 12, and an induction column 13 is installed inside the shell 3. When the sensing columns 13 are energized and the third shaft 10 rotates, the metal rod 12 located between the two sensing columns 13 rotates accordingly. When the metal rod 12 and the sensing columns 13 are located in a straight line, the electrons on the sensing columns 13 will first move to the metal rod 12 and then to the sensing columns 13, thereby generating current. When water flows through the smart water meter body 1, the metal rod 12 will continuously rotate, thereby generating current intermittently. Then, the current state is detected by the controller 16 to determine the water flow rate passing through the smart water meter body 1.

The PCB board detects the current generated on the sensing column 13 to determine the water flow through the smart water meter body 1.

[0028] Working principle: When in use, the sensing column 13 is energized, and the water flow passing through the smart water meter body 1 will drive the blade 5 to move, thereby driving the first rotating shaft 4 to rotate. When the first rotating shaft 4 rotates, it will drive the second gear 8 to rotate through the first gear 6, thereby driving the first bevel gear 9 to rotate, so that the third rotating shaft 10 rotates. When the third rotating shaft 10 rotates, the metal rod 12 located between the two sensing columns 13 rotates accordingly. When the metal rod 12 and the sensing column 13 are located in a straight line, the electrons on the sensing column 13 will first move to the metal rod 12 and then to the sensing column 13, thereby generating current. When water flows through the smart water meter body 1, the metal rod 12 will rotate continuously, thereby generating current intermittently, and then the current state is detected by the controller 16 to determine the water flow through the smart water meter body 1.
