Description

Technical Field

[0001] This invention pertains to flow meter accessories, and more specifically relates to a shaftless impeller pulse generator. Background Technology

[0002] Currently, most flow meters used in various locations (such as smart electronic water meters and smart electronic heat meters) contain either disposable lithium batteries or rechargeable batteries, with the exception of a few that use external power supplies. These battery-powered electronic meters are inconvenient to replace or recharge due to varying power consumption rates.

[0003] This invention provides a solution for a shaftless impeller pulse generator that can provide unlimited power to electronic instruments without the need for external power sources or other batteries. Summary of the Invention

[0004] This invention is implemented as follows: A rotatable power-generating impeller assembly is fixed within a housing made of a non-magnetic metal or non-metallic material. This assembly is an inward-facing impeller made of a non-magnetic material. Its blades differ from ordinary blades; they are multiple blades spirally grown inward at a specific angle. Multiple strong magnets are fixed to the edge of the inward-facing impeller, which is then inserted into a bearing. A sealed box containing a power-generating coil is fixed outside the housing near the inward-facing impeller, with the coil positioned as close as possible to the strong magnets on the inward-facing impeller.

[0005] In the production of this invention, the sealed box with the generator coil and the mechanical assembly with the generator impeller can be produced separately, and then they can be assembled and fixed together to complete the production of this invention.

[0006] This invention can be connected to an electronic fluid instrument using methods such as threads, flanges, or welding, or it can be directly designed into the electronic instrument. When fluid flows through the pipes of the electronic instrument, the fluid drives the inward-facing impeller to rotate. Each strong magnet on the edge of the inward-facing impeller periodically approaches the generating coil inside the sealed box. The generating coil generates an electromotive force when the strong magnets approach and move away. This generating coil is connected to a supercapacitor, and a power management circuit such as a rectifier is added to the circuit. This management circuit allows the generating coil to charge the supercapacitor but does not allow the generating coil to consume the electrical energy stored in the supercapacitor. The supercapacitor, connected to the electronic instrument, can then supply power to the electronic instrument. In this way, the electronic instrument does not require a separate power source.

[0020] The invention is implemented as follows: a rotatable generator impeller assembly is fixed inside a housing made of non-magnetic metal or non-metallic material. The assembly is an inward-facing impeller (8) made of non-magnetic material. Its blades are different from ordinary blades; they are multiple blades that grow inward spirally at a certain angle. Multiple strong magnets (9) are fixed on the edge of the inward-facing impeller (8), and then the inward-facing impeller (8) is inserted into a bearing (10). A sealed box containing a generator coil (5) is fixed outside the housing near the inward-facing impeller (8), with the generator coil (5) as close as possible to the housing of the strong magnets (9) on the inward-facing impeller (8).

[0021] In the production of this invention, the sealed box with the generator coil (5) and the mechanical assembly with the generator impeller (8) can be produced separately, and then they can be fixed together in combination to complete the production of this invention.

[0022] The invention can be connected to the electronic fluid instrument using methods such as threads, flanges, or welding, or the invention can be directly designed into the electronic instrument. When fluid flows through the pipes of the electronic instrument, the fluid will drive the inward impeller (8) to rotate. Each strong magnet (9) on the edge of the inward impeller (8) will periodically approach the generator coil (5) inside the sealed box. The generator coil (5) will generate an electromotive force when the strong magnet (9) approaches and moves away. The generator coil (9) is connected to a supercapacitor, and a power management circuit such as a rectifier is added to the circuit. This management circuit can only allow the generator coil (9) to charge the supercapacitor, and cannot allow the generator coil (9) to consume the electrical energy stored in the supercapacitor. The supercapacitor can then supply power to the electronic instrument when connected to it. In this way, the electronic instrument does not need any other power source.
