The water flows through the jet holes to impact the water impeller, and the multi-stage magnets arranged on the water impeller rotate to enable the stator coil to generate induced electromotive force. The generator has the characteristics of no shaft sealing water leakage, low starting torque and high generating efficiency, and can meet the power supply use of electric control display management of some micro-power equipment.
Description
Technical Field
The invention relates to a miniature hydraulic disc type permanent magnet generator, and belongs to the technical field of hydraulic power generation.
Background
At present, as many water purifiers without electricity need to manage the service life of a filter element and monitor water quality, dry batteries are generally used for supplying power, and the batteries need to be replaced frequently. Because the water purifier has small flow, although a plurality of miniature hydroelectric generators are on the market, one section is not suitable for the water purifier, and the effects can be achieved and the use requirements can be met because ingenious, reasonable and professional designs are needed for starting, energy efficiency and the like of the generators.
Disclosure of Invention
The miniature hydraulic disc type permanent magnet generator comprises a shell, a water impeller, a multi-stage magnet, stator coils and the like, and is characterized in that the shell consists of a lower shell, a middle shell and an upper shell, wherein the lower shell and the middle shell are installed to form an impeller chamber, the impeller chamber is provided with a jet hole, the multi-stage magnet is flatly arranged between blades and a middle shaft on the water impeller, the middle shell and the upper shell are installed to form a water outlet waterway, a placement cavity for the stator coils is arranged between the waterway and the middle shaft, and six stator coils are placed in the placement cavity; the middle shell is provided with a water passing hole, and the upper shell is provided with a water outlet and a stator coil lead outlet. The water flowing direction of the water passing Kong Shishun of the middle shell is gradually increased. The water impeller and the multipolar magnet form a rotor, and each magnetic pole direction is perpendicular to the stator coil. The water impeller is provided with a shaft sleeve. The shaft sleeve is provided with a shaft rod which is fixed on the lower shell and the middle shell, and sealing rings are arranged among the lower shell, the middle shell and the upper shell through screw fastening to form a sealed waterway. The water flows through the jet holes to impact the water impeller, and the multi-stage magnets arranged on the water impeller rotate to enable the stator coil to generate induced electromotive force. The generator has the characteristics of no shaft sealing water leakage, low starting torque and high generating efficiency.
