Therefore, a new miniature DC hydroelectric generator is needed.

Utility model content

The technical problem to be solved by the utility model is to provide a miniature DC hydraulic generator, which is environmentally friendly, energy-saving, high in reliability, long in service life, low in noise, and can effectively utilize hydraulic power.

In order to solve the above-mentioned technical problems, the utility model miniature DC hydraulic generator includes a housing, a water inlet, a water outlet and a generator. The water inlet and the water outlet are connected to the housing, and one end of the housing is provided with a closed cavity. The generator is set in a closed cavity, and the cavity at the other end of the housing is provided with a driven magnet, a driven impeller, a shaft, a driving impeller, and a driving magnet. The driving impeller is directly worn on the shaft, and the driving magnet is set on the driving impeller. , the shaft of the generator coincides with the center line of the fixed shaft of the driving impeller, the driven impeller is arranged on the shaft of the generator, the driven magnet is arranged on the driven impeller, and the driven magnet and the driving magnet are arranged oppositely.

A generator cover is arranged on the top of the closed cavity, and the closed cavity is tightly fitted with the generator cover.

A slot is provided on the driven impeller, and the driven magnet is snapped on the driven impeller through the slot.

The driving impeller is provided with a guide cover, and the guide cover is provided with a guide notch.

The utility model has the following beneficial effects: first, the water flow flows through the impeller shroud from the water inlet, and drives the driving impeller and the driving magnet to rotate, and the rotation of the driving magnet drives the driven magnet to rotate, and then drives the driven impeller to rotate, and finally drives the power generation The shaft of the generator rotates, and the shaft of the generator rotates to output DC voltage to achieve the purpose of hydropower generation, environmental protection and energy saving. Second, the generator, driven magnet, and driven impeller are arranged in a closed space, which is isolated from the chamber where the driving impeller and the driving magnet are located through which water flows, so they will not be soaked in water, greatly improving reliability and extending service life life. Thirdly, the shaft sleeve is removed between the shaft and the impeller, and they are directly in contact with a large area, which improves the service life and reduces the noise during product operation. Fourth, the diversion cover is specially designed with diversion notches, so that water flows through the notches to drive the active impeller to rotate, maximizing the use of hydraulic power.

One end of the casing is provided with a closed cavity, the generator 2 is arranged in the closed cavity, and the cavity at the other end of the casing is provided with a driven magnet 3, a driven impeller 4, a shaft 9, a driving impeller 8, a driving magnet 5, and a driving impeller 8 Directly threaded on the shaft 9, the active magnet 5 is arranged on the active impeller 8, the shaft of the generator 2 coincides with the center line of the fixed shaft 9 of the active impeller 8, and the driven impeller 4 is arranged on the shaft of the generator 2, from which A driven magnet 3 is arranged on the movable impeller 4, and the driven magnet 3 and the driving magnet 5 are arranged oppositely.

A generator cover 1 is arranged on the top of the closed cavity, and the closed cavity is tightly fitted with the generator cover 1 .

The driven impeller 4 is provided with a clip slot, and the driven magnet 3 is clipped on the driven impeller 4 through the clip slot.

The driving impeller 8 is provided with a guide cover 7, and the guide cover 7 is provided with a guide notch.

The water flows from the water inlet through the shroud, driving the driving impeller and the driving magnet to rotate, and the rotation of the driving magnet drives the driven magnet to rotate, which in turn drives the driven impeller to rotate, and finally drives the shaft of the generator to rotate, and the rotation of the generator shaft outputs DC voltage , to achieve the purpose of hydropower generation, environmental protection and energy saving.

The generator, driven magnet, and driven impeller are arranged in a closed space, which is isolated from the chamber where the driving impeller and the driving magnet are located through which water flows, so they will not be soaked in water, greatly improving reliability and prolonging service life.

The shaft sleeve is removed between the shaft and the impeller, and a large area is in direct contact, which improves the service life and reduces the noise during product operation.

The diversion cover is specially designed with a diversion notch, so that water flows through the notch to drive the driving impeller to rotate, maximizing the use of hydraulic power.
