Abstract

The invention provides a wind power generation device with a self-adjusting mechanism, comprising: a base, an air outlet disk, a plurality of blades and a generator. The blade is driven by the wind, and the deflector of the blade is pushed to the partition plate of the base to drive the base to rotate, so that the generator connected to the base operates to generate electricity. Wherein, the wind of unequal intensity entering the baffle will push the blade unequally, so that the air outlet on the baffle and the air outlet on the air outlet automatically adjust the overlapping area to adjust the exhaust air volume to an unequal degree. In turn, the operating speed of the blade is automatically adjusted; when the wind is too strong, the wind deflector will abut the inlet of the wind adjacent to the blade, so that the wind power generator does not continue to accelerate the rotation. Thereby, the wind power generation device can be prevented from being excessively worn due to excessive wind force, resulting in a decrease in service life or damage.

Description

Wind power generation device with self-adjusting mechanism

The present invention relates to a wind power generator having a self-adjusting mechanism, particularly a wind power generator having a cylindrical shape and having a small volume, and having a protective structure to prevent damage to the device when the wind is excessively large.

A wind power generation device is a power generation device that converts natural gas flow energy into mechanical energy and connects the generator to operate to generate electricity.

At present, the conventional wind power generation device receives wind energy from a windmill and converts it into mechanical energy and then converts it into electric power, as shown in FIG. However, the conventional wind power generation device 10 does not have a self-protection mechanism. If the wind is too strong, it is easy to over-operate, causing the wear axis and the service life to be degraded, or the blade 11 or the support base 12 to be acoustically broken or Fall down and create a situation that requires maintenance. However, the conventional wind power generation device 10 is not expensive and expensive because of its high cost and bulkiness. Moreover, when the wind and the wind direction are often different depending on the season, it is easy for the wind power generator that needs to receive the wind in a certain direction to have a problem that energy cannot be concentrated. However, conventional wind power installations can also cause serious damage to the landscape, posing a life threat to birds and bats flying in the air.

Based on the above reasons, an object of the present invention is to provide a wind power generator having a self-adjusting mechanism, particularly a wind power generator having a cylindrical shape and having a small volume and having a protective structure to prevent damage when the wind is excessively large.

In order to achieve the foregoing object, an object of the present invention is to provide a wind power generation device having a self-adjusting mechanism, comprising: a base, an air outlet disk, a plurality of blades, and a generator. The base is provided with a plurality of partition plates which are tangential to the edge of the base and are curved, and the partition plates are arranged in a circle at a distance from each other, wherein the length of the base is One end has a bottom plate, and the bottom plate is provided with a predetermined number of first first pivot holes; the air outlet plate is provided with a plurality of air outlets and a plurality of second pivot holes opposite to the first pivot holes; The utility model has a deflector, a windshield portion and a pivot rod. At least one end of the two ends of the pivot rod has a spring, and the pivot rod is pivotally disposed on the first pivot hole of the base and the second pivot of the air outlet disc There is a sleeve between the holes and between the pivot rod and the first pivot hole and the second pivot hole. Wherein the windshield has a stop block; and the generator is pivotally connected to the base.

In the present invention, the wind deflector pushes the deflector of the blade to the partition plate of the base to drive the base to rotate, and the generator connected to the base operates to generate electricity. Among them, the blade will automatically rotate according to the size of the wind to adjust the running speed of the base. When the wind enters the deflector, it will be discharged through the air outlet on the baffle and the corresponding air outlet on the air outlet. However, when the wind is increased, the blade pivoted between the first pivot hole of the base and the second pivot hole of the air outlet disk rotates until the stop block of the windshield portion of the blade reaches the adjacent blade. On the pivot. Wherein, the air outlet on the baffle and the air outlet on the air outlet disc are centered on the pivot rod, and a plurality of arc-shaped holes are formed by the same radius. When the blade is not rotated, the air outlet and the air outlet are in a positional relationship that is staggered from each other; when the blade rotates due to the wind force, the blade overlaps with the air outlet due to the rotation, and the corresponding opening will discharge excess The wind volume, the greater the wind, the more the amount of overlap, at the same time, the spring provided on the pivot rod is twisted to store the elastic force; when the wind is too strong, the blade rotates to the stop of the wind shield to reach the pivot of the adjacent blade When it is up, the air outlet on the baffle will completely coincide with the air outlet on the air outlet disk. At this time, the wind power generation device has the largest exhaust air volume, however, the wind deflecting portion of the wind deflecting portion abuts against the wind of the adjacent blade. The entrance, so the wind power plant will not continue to accelerate the rotation. Thereby, the wind power generation device can be prevented from being excessively worn by the shaft due to excessive wind force, resulting in problems such as a decrease in service life or damage. Wherein, when the wind is weakened, the spring force stored by the springs at both ends of the blade will cause the blade to rebound, so that the wind energy can enter the wind power generator again to drive the base to operate.

According to an embodiment of the invention, one end of the baffle is provided with a baffle perpendicular to one side of the baffle, and the baffle has an air outlet. And at least one support column is disposed on both ends of the baffle.

According to an embodiment of the invention, the spring is a torsion spring.

According to an embodiment of the invention, the blade has a sleeve between the first pivot hole and the second pivot hole.
