Description

Technical Field

[0001] The present invention relates to the technical field of small wind power generation devices, specifically a portable wind power generation device. Background Art

[0002] Nowadays, a large number of devices need to be powered by batteries. Especially when conducting outdoor adventures or explorations, more devices are required. However, when there is no power source outdoors, the batteries of the devices themselves are difficult to provide long-term power supply to meet the needs of device use. Some devices even do not have batteries and cannot be driven without a power source. And most of the existing mobile power supplies have a small capacity, and the maximum capacity cannot meet the operation of high-power devices. The capacity of a mobile power supply is fixed, and it cannot provide electrical energy again after being used up. It needs to be connected to alternating current / direct current to charge the battery again. Therefore, generators are commonly used for power generation in outdoor activities. Conventional fuel generators are not environmentally friendly, so environmentally friendly energy generators are becoming more and more popular.

[0003] Wind is one of the pollution-free energy sources. Moreover, it is inexhaustible and renewable. And wind power generation has less noise and is very environmentally friendly. However, the portable wind power generation equipment in outdoor activities is limited by size problems and cannot achieve high power generation efficiency. Summary of the Invention

[0004] To solve the problem of low power generation efficiency of the above-mentioned portable wind power generation equipment, the present invention provides a portable wind power generation device, which drives the power generation component through a fan group to perform high-efficiency power generation.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a portable wind power generation device, including a housing, a power generation component, a fan group and an electric box. The power generation component is fixedly connected to the housing. The fan group is arranged inside the housing. The electric box is fixed to the bottom of the housing. The electric box includes a controller and a storage battery. By arranging the power generation component, the fan group and the electric box inside the housing, the size of the device is reduced, and the fan group drives the power generation component to achieve high-efficiency power generation.

[0006] As an optimization, the power generation component includes a generator, a power generation shaft and a power generation gear. The top of the generator is fixedly connected to the inner top of the housing through a fixing block. The power generation shaft is arranged in front of the generator. The inside of the power generation gear is hollow. A spiral wing is fixed inside the power generation gear. One side of the spiral wing is fixedly connected to the power generation gear, and the other side of the spiral wing is fixedly connected to the power generation shaft. The front end of the power generation shaft passes through the axis of the power generation gear and is arranged in front of the power generation gear. The power generation shaft is fixed to the power generation gear through the spiral wing. The spiral wing can rotate with the wind, so that the spiral wing drives the power generation gear to rotate and drives the generator.

[0007] As an optimization, the fan group includes a first fan, a second fan, a third fan, and a fourth fan. The first fan, the second fan, the third fan, and the fourth fan each include fan blades, a fan housing, and a rotating shaft. The fan blades are arranged on the rotating shaft. The fan housing is cylindrical. A fixed grille is provided on the bottom surface of one side of the fan housing. One end of the rotating shaft is rotatably connected to the center of the fixed grille. The entire fan is fixed by the fan housing. The fan is movably connected to the fixed grille. When the fan rotates, the rotating shaft and the gear cooperate to rotate for power generation.

[0008] As an optimization, the housing is a rectangular box with an open front side and an open rear side. A first opening is provided at the front end of the right side of the box body, and a second opening is provided at the rear end of the left side of the box body. The tops of the first opening and the second opening are both arranged at the top of the box body. The widths of the first opening and the second opening are the same as the width of the fan housing. By providing the first opening and the second opening, it is convenient to pull out the second fan and the third fan from the inside of the housing.

[0009] As an optimization, the first fan is arranged at the front end of the power generation shaft. The other end of the rotating shaft of the first fan is fixedly connected to the front end of the power generation shaft. Gears are adjacent to the outer edges of the other sides of the housings of the second fan, the third fan, and the fourth fan. An activity grille is provided at the center of the gear and is fixedly connected to the rotating shaft. The gear is meshed with the power generation gear. The rotation of the fan drives the activity grille and the gear to rotate. The power generation gear is driven to rotate by the meshing of the gear with the power generation gear for power generation.

[0010] As an optimization, a fixed ring is provided between the power generation gear and the first fan. The power generation shaft and the fixed ring are coaxial. The top of the fixed ring is fixedly connected to the top of the housing through a fixed block. A first slot is provided on the right side of the fixed ring. A first connecting rod is fixed to the top of the fan housing of the second fan. The other end of the first connecting rod is rotatably connected to the first slot in a damped manner. An arc-shaped slot is fixed to the rear side of the generator. A second connecting rod is fixed to the top of the fan housing of the third fan. The other end of the second connecting rod is dampedly connected to the arc-shaped slot. The bottom of the fan housing of the fourth fan is fixed to the upper side of the bottom of the housing through a fixed block. The second fan and the third fan are rotatably connected to the first slot and the second slot, so that the second fan and the third fan can be pulled up from the bottom of the power generation gear and can extend out of the housing.

[0011] As an optimization, the second fan is arranged inside the first opening, the third fan is arranged inside the second opening. The gears of the second fan and the third fan are arranged at the rear side of the fan housing, and the gear of the fourth fan is arranged at the front side of the fan housing.

[0012] As an optimization, the spiral direction of the spiral wing and the rotation direction of the first fan are both counterclockwise, and the rotation directions of the second fan, the third fan, and the fourth fan are all clockwise. The spiral wing and the first fan can drive the power generation gear to rotate counterclockwise, and the second fan, the third fan, and the fourth fan all rotate clockwise to drive the power generation gear to rotate counterclockwise.

[0013] As an optimization, a handle is provided at the top of the housing, and a counterweight is provided on the inner side of the bottom of the housing. The stability of the power generation device is improved by the counterweight, and the portability of the power generation device is achieved through the handle.

[0014] The overall beneficial effects of this solution are as follows: A portable wind power generation device has the following advantages: (1) By setting multiple fans to rotate to drive the power generation shaft to rotate, the generator can generate electricity, improving the power generation efficiency of the portable power generation device; (2) A spiral wing is provided between the power generation shaft and the power generation gear.

The spiral wing and the first fan drive the power generation gear to rotate counterclockwise. The two rotation directions work together to improve the rotation efficiency of the power generation shaft; (4) The second fan is fixed inside the housing through a fixing ring, and the third fan is fixed inside the housing through an arc-shaped groove, enabling the second fan and the third fan to be stored inside the housing, greatly reducing the volume of the power generation device; (5) Multiple fans drive the same motor shaft simultaneously, which can greatly reduce the driving torque and facilitate the use of this device in the case of low wind power; (6) By providing openings on the left and right sides of the housing, the second fan and the third fan can be unfolded outward during power generation, improving the power generation efficiency and being convenient to operate. This device enables users to generate electricity conveniently when using electricity outdoors. Through special structural design, the space utilization rate inside the device can be greatly improved and the volume of the device can be reduced when the device is in the retracted state; when in the unfolded state, multiple fans and spiral wings work together to rotate efficiently, which can greatly improve the power generation efficiency of the device.
