Technical Field

The utility model relates to a miniature hydroelectric generation technical field particularly, relates to a miniature hydroelectric generator.

Background

With the development of industry, micro hydroelectric generators are gradually widely used, such as: is commonly used in the bathroom field. Specifically, a miniature hydroelectric generator is mounted within a faucet, and generates electricity from the flow of water through the faucet, the generated electricity being used as a power supply for a light effect or other accessories.

At present, miniature hydroelectric generator generally includes supporting component to and supporting component pivoted runner assembly relatively, rivers can drive the relative supporting component rotation of runner assembly, in order to cut the activity of magnetic induction line. Because the rotating assembly rotates at a high speed relative to the supporting assembly for a long time, although a wear-resistant gasket is arranged between the supporting assembly and the rotating assembly, under the clamping rotation of the supporting assembly and the rotating assembly, the service life of the wear-resistant gasket cannot be well guaranteed, and the service life of the miniature hydroelectric generator is too short. In view of the above, the inventors of the present invention have made a study of the prior art and then have made the present application.

SUMMERY OF THE UTILITY MODEL

The utility model provides a miniature hydroelectric generator aims at improving prior art, miniature hydroelectric generator life too short's problem.

In order to solve the technical problem, the utility model provides a miniature hydroelectric generator, including power generation mechanism, it power generation mechanism contains:

a support assembly including a coil;

the rotating assembly comprises a rotating shaft arranged on the supporting assembly, an impeller rotatably arranged on the rotating shaft, an upper wear plate and a lower wear plate which are respectively sleeved on the rotating shaft and clamped between the impeller and the supporting assembly, and a permanent magnet arranged on the impeller;

the impeller can drive the permanent magnet to rotate so as to enable the coil to cut the magnetic induction line to generate electricity; the rotating assembly rotates relative to the supporting assembly, so that the upper wear-resisting plate and the lower wear-resisting plate can be mutually rotated and rubbed.

As a further optimization, the upper wear-resistant plate and the lower wear-resistant plate are both sheet-shaped geometric bodies made of wear-resistant materials.

As a further optimization, the micro hydroelectric generator comprises a water guide sleeved on the impeller, and the water guide is provided with a slant water hole which is obliquely arranged and opposite to the impeller.

By adopting the technical scheme, the utility model discloses can gain following technological effect:

the utility model discloses a miniature hydroelectric generator has long service life's beneficial effect. Specifically, when the miniature hydroelectric generator is used, the impeller drives the rotating shaft and the permanent magnet to rotate together relative to the supporting component; the friction force between the upper wear-resistant plate and the impeller and the friction force between the lower wear-resistant plate and the support assembly are larger than the friction force between the upper wear-resistant plate and the lower wear-resistant plate; therefore, the impeller drives the upper wear plate to rotate relative to the lower wear plate and the supporting component integrally. Namely: the rotational friction between the impeller and the support assembly is mainly concentrated between the upper wear plate and the lower wear plate. Because the friction between the upper wear-resistant plate and the lower wear-resistant plate is smaller, and the upper wear-resistant plate and the lower wear-resistant plate are more wear-resistant, the service lives of the upper wear-resistant plate and the lower wear-resistant plate can be greatly prolonged.

Meanwhile, in the long-term use process, the upper wear-resistant sheet and the lower wear-resistant sheet are difficult to avoid thinning, and the wear-resistant requirement is difficult to meet. At the moment, the upper wear plate and the lower wear plate rotate and rub at a high speed, the generated heat can enable the friction surfaces of the upper wear plate and the lower wear plate to be locally melted, the upper wear plate and the lower wear plate are combined into a whole, and the requirement of the wear plate between the impeller and the supporting assembly is met again.

Through above-mentioned technical scheme, the miniature hydroelectric generator of present case compares prior art's miniature hydroelectric generator, and improvement impeller that can very big degree and the wear-resisting life between the supporting component, and then improve miniature hydroelectric generator's life greatly.

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1, 2 and 3, in the present embodiment, a micro hydro-generator includes a power generation mechanism 2, and the power generation mechanism 2 includes:

the impeller 6 can drive the permanent magnet 9 to rotate, so that the coil 14 cuts the magnetic induction lines to generate electricity; the rotating assembly 3 rotates relative to the supporting assembly 4, so that the upper wear plate 10 and the lower wear plate 11 can be mutually rotated and rubbed.

Specifically, when the micro hydroelectric generator of the embodiment is in use, the impeller 6 drives the rotating shaft 12 and the permanent magnet 9 to rotate together relative to the support assembly 4; because the friction force between the upper wear-resistant plate 10 and the impeller 6 and the friction force between the lower wear-resistant plate 11 and the support assembly 4 are both larger than the friction force between the upper wear-resistant plate 10 and the lower wear-resistant plate 11; therefore, the impeller 6 drives the upper wear plate 10 to rotate integrally with the lower wear plate 11 and the support assembly 4. Namely: the rotational friction between the impeller 6 and the support assembly 4 is mainly concentrated between the upper wear plate 10 and the lower wear plate 11. Since the friction between the upper wear-resistant plate 10 and the lower wear-resistant plate 11 is smaller, and the upper wear-resistant plate 10 and the lower wear-resistant plate 11 are more wear-resistant, the service life of the upper wear-resistant plate 10 and the lower wear-resistant plate 11 can be greatly prolonged.

Meanwhile, in the long-term use process, the upper wear-resistant plate 10 and the lower wear-resistant plate 11 are difficult to avoid thinning, and the requirement of wear resistance is difficult to meet. At this time, due to the high-speed rotation friction between the upper wear plate 10 and the lower wear plate 11, the generated heat can locally melt the friction surfaces of the upper wear plate 10 and the lower wear plate 11, so that the upper wear plate 10 and the lower wear plate 11 are combined into a whole, and the requirement of the wear plate between the impeller 6 and the support assembly 4 is met again.

As illustrated in fig. 2, in the present embodiment, the upper wear plate 10 and the lower wear plate 11 are both plate-shaped geometric bodies made of wear-resistant materials.

As shown in fig. 1 and 2, in the present embodiment, the micro hydro-generator includes a water guide 1 sleeved on an impeller 6, and the water guide 1 has a slant water hole 15 obliquely arranged with respect to the impeller 6. When the water flow passes through the inclined water holes 15, the water flow of the inclined nozzle impeller 6 is generated, and the impeller 6 is driven to rotate.

As shown in fig. 1 and 2, in the present embodiment, the impeller 6 includes a runner portion 8 having a rotation chamber 16 therein, and a vane portion 7 disposed in the runner portion 8. Wherein the permanent magnet 9 is an annular geometry arranged in the rotation chamber 16. Specifically, the permanent magnet 9 may be disposed in the rotation cavity 16 by bonding, combining, and fastening, so that the impeller 6 may drive the permanent magnet 9 to rotate together.

As shown in fig. 1 and 2, in the present embodiment, the power generation mechanism 2 includes a conductive member 5 disposed on the support member 4, and the conductive member 5 includes a PCB 18 electrically connecting the coil 14, a temperature sensor disposed on the PCB 18, and a terminal wire 19 disposed on the PCB 18.
