Description

Shaftless impeller pulse type power generation device Technical Field The invention belongs to a flow instrument accessory, and particularly relates to a shaftless impeller pulse type power generation device. Background Currently, flow electronic meters (such as intelligent electronic water meters, intelligent electronic heat meters, etc.) are used in various places, and most of the flow electronic meters are provided with disposable lithium batteries or rechargeable secondary batteries except for a few of the flow electronic meters which are powered by an external power supply. These electronic meters, which are made up of built-in batteries, are cumbersome to replace or recharge due to the different rates of consumption of electricity by the meter. The present invention provides a solution to providing a shaftless impeller pulse power generation device that can provide unlimited power to electronic meters without the aid of external power supplies and other batteries. Disclosure of Invention The invention is realized by fixing a set of rotatable power generation impeller assembly in a shell made of non-magnetic metal or non-metal materials. The assembly is an inner-converging impeller made of non-magnetic materials, the blades of the inner-converging impeller are different from the common blades, a plurality of blades at a certain angle are spirally grown inwards, a plurality of strong magnets are fixed on the edge of the inner-converging impeller, and then the inner-converging impeller is inserted into a bearing. A sealing box with a generating coil inside is fixed at the position, which is close to the inner converging impeller, outside the shell, and the generating coil is close to the shell of the strong magnet on the inner converging impeller as much as possible. When the invention is produced, the sealing box with the generating coil and the mechanical assembly with the generating impeller component can be separately produced, and then the sealing box and the mechanical assembly with the generating impeller component are combined and fixed together, thus the complete production of the invention can be completed. The invention is connected with the electronic fluid instrument by adopting a method such as screw threads, flanges or welding, and the like, and the invention is probably directly designed into the electronic instrument. When fluid flows through a pipeline of the electronic instrument, the fluid pushes the inner converging impeller to rotate, each strong magnet on the edge of the inner converging impeller periodically approaches to a power generation coil in the sealing box, the power generation coil generates electromotive force when the strong magnet approaches to or away from the power generation coil, the power generation coil is connected with the super capacitor, and a power management circuit such as rectification is added in the circuit. Thus, the electronic instrument does not need other power sources. Fig. 1 is a front cross-sectional view of the present invention.
