Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a portable wind power generation device. Background Technology

[0002] The descriptions in this section provide background information relating to this disclosure and do not constitute prior art.

[0003] Common devices for supplementing power during outdoor camping include diesel generators and solar panels. Diesel generators are heavy and bulky, making them inconvenient to carry. Solar panels have certain limitations in their operating environment; they cannot store electricity at night, which is crucial for nighttime lighting. Furthermore, their energy conversion is extremely limited in cloudy or rainy weather. Wind power generation devices have far fewer limitations. Even at night, they can convert electricity as long as there is wind. Therefore, wind power generation devices have significant advantages in environments with ample wind, such as high mountains or plains. However, existing wind power generation devices are bulky and inconvenient to carry. Utility Model Content

[0047] Please see Figure 1-7 This utility model provides a technical solution: a portable wind power generation device, comprising:

[0048] A vertical generator 1 has a round rod 4 fixedly mounted coaxially at its upper output end;

[0049] A flexible folding blade mechanism 5 is fixedly assembled at the upper end of the round rod 4;

[0050] A storage battery 2 is fixedly mounted on the lower end of the vertical generator 1 via a connecting flange;

[0051] A charge / discharge controller 7 is fixedly mounted on the outer wall of the vertical generator 1, and is electrically connected between the vertical generator 1 and the battery 2.

[0052] The flexible folding blade mechanism 5 has a protective cover 9 attached to its upper end after folding.

[0053] Specifically, in this embodiment, the vertical generator 1 is an application of existing technology. The rotating rod 4 drives the upper output end of the vertical generator 1 to rotate and generate electricity. The charge and discharge controller 7 is used to protect the battery 2 from charging and discharging. The charge and discharge controller is an electronic device used to manage the charging and discharging process of the battery. It ensures that the power supply always works at the maximum power point by intelligently adjusting the working voltage of the power supply, thereby improving energy utilization efficiency.

[0054] Furthermore, the unfolded flexible folding blade mechanism 5 drives the round rod 4 to rotate under the wind. The rotating round rod 4 drives the upper output of the vertical generator 1 to rotate and generate electricity. The electrical energy generated by the vertical generator 1 is controlled by the charge and discharge controller 7 and sent to the storage battery 2 for storage. The discharge of the storage battery 2 is also controlled by the charge and discharge controller 7 to achieve stable discharge. The storage battery 2 is used to supplement power for outdoor camping.

[0055] More specifically, the flexible folding blade mechanism 5 can be folded to reduce the size of the device; and the round rod 4, the flexible folding blade mechanism 5, the vertical generator 1, the battery 2 and the charge and discharge controller 7 are assembled to form an integral structure. When the flexible folding blade mechanism 5 is stored, the device is cylindrical in shape, and a protective cover 9 is attached to the upper end for shielding, making it easy to put the whole device into the vehicle for carrying.

[0056] Understandably, the device is placed upright on the ground when in use.

[0057] In some embodiments, the flexible folding blade mechanism 5 includes:

[0058] Bearing 51, whose inner ring surface is fixedly sleeved on the upper end of the outer wall of the round rod 4;

[0059] There are two annular baffles 52, which are distributed parallel to each other vertically.

[0060] Two annular baffles 52 are fixedly assembled on the upper end of the outer wall of the round rod 4, and a gap is left between the annular baffles 52 and the outer wall of the bearing 51 on the same side;

[0061] Notches 57 are provided at the front, back, left and right edges of the lower annular baffle 52;

[0062] The outer wall of the bearing 51 is uniformly and circumferentially fixedly fitted with four first hinge seats 53.

[0063] A support rod 54 is hinged to the first hinge seat 53, and its horizontal bottom surface is attached to the top surface of the lower annular baffle 52.

[0064] A fixing bolt 58 is screwed between the inner side of the upper surface of the support rod 54 and the top surface of the lower annular baffle 52;

[0065] The inner side of the bottom surface of the support rod 54 is equipped with a hinged connecting rod structure 55, which is vertically arranged;

[0066] A flexible fan-shaped blade 56 is attached and fixed between the hinged connecting rod structure 55 and the bottom surface of the support rod 54.

[0067] Specifically in this embodiment, the support rod 54 is connected to the outer wall of the bearing 51 and rotates on the outer wall of the round rod 4. It rotates until the upper and lower reserved through holes on the inner side of the support rod 54 are connected to the reserved screw holes on the top surface of the lower annular baffle 52. At this time, the support rod 54 and the lower annular baffle 52 are fixedly connected by the fixing bolt 58 passing through the reserved through holes and screwed into the reserved screw holes.

[0068] The flexible fan-shaped blade 56 is specifically a flexible film, which can be made of tough plastic film or densely woven fiber cloth;

[0069] Furthermore, when the flexible folding blade mechanism 5 is unfolded, the support rod 54 and the lower annular baffle 52 are fixedly connected by the fixing bolt 58. At this time, the hinged connecting rod structure 55 droops due to gravity, and the flexible fan-shaped blade 56 between the hinged connecting rod structure 55 and the bottom surface of the support rod 54 unfolds.

[0070] When folding the flexible folding blade mechanism 5, remove the fixing bolt 58, rotate the support rod 54 and the outer ring of the bearing 51, and rotate the four support rods 54 to correspond to the positions of the four notches 57. The lower annular baffle 52 no longer supports the support rods 54, and the support rods 54 flip down to a vertical state through the hinge at the first hinge seat 53. The flexible fan-shaped blades 56 between the hinge link structure 55 and the bottom surface of the support rods 54 are folded.

[0071] Understandably, the removed fixing bolt 58 can be screwed into the reserved screw hole of the lower annular baffle 52 when the device is being carried, and then removed when the support rod 54 needs to be fixed. This method avoids the loss caused by carrying the fixing bolt 58 separately.

[0072] In some embodiments, the hinged link structure 55 includes:

[0073] The second hinge seat 551 is fixedly assembled to the inner side of the bottom surface of the support rod 54;

[0074] A connecting rod 552 is hinged to the second hinge seat 551, and a flexible fan-shaped blade 56 is glued and fixed between the connecting rod 552 and the bottom surface of the support rod 54.

[0075] Specifically in this embodiment, the connecting rod 552 is hinged at the second hinge seat 551, and the connecting rod 552 and the support rod 54 can change their included angle by hinged flipping.

[0076] In some embodiments, a rubber layer is attached to the lower edge of the protective cover 9 and is attached to the top surface of the vertical generator 1. The rubber layer acts as a buffer to prevent the protective cover 9 from colliding with the top surface of the vertical generator 1 after it is fastened.

[0077] In some embodiments, a U-shaped handle 12 is fixedly fitted to the outer wall of the protective cover 9, which facilitates the fastening or removal of the protective cover 9 by gripping the U-shaped handle 12.

[0078] In some embodiments, an external threaded ring 10 is coaxially fixedly mounted on the center of the top surface of the vertical generator 1;

[0079] The lower end of the inner wall of the protective cover 9 is provided with an internal thread, which is screwed to the outer wall of the external threaded ring 10.

[0080] Specifically, in this embodiment, the external threaded ring 10 is screwed to the lower end of the protective cover 9, and the U-shaped handle 12 facilitates the overall carrying of the device.

[0081] In some embodiments, a ball 6 is fixedly mounted on the upper end of the round rod 4. The ball 6 serves as the top of the device to prevent the sharp edges of the upper end of the round rod 4 from causing scratches or bumps to the user when the ball 6 is not installed.

[0082] In some embodiments, an annular cover 8 is slidably sleeved on the outer wall of the vertical generator 1, which is fastened to the outside of the connecting flange on the top surface of the battery 2. The annular cover 8 provides shielding and protection for the connection between the lower end of the vertical generator 1 and the battery 2.

[0083] Furthermore, the lower edge of the annular cover 8 is provided with an adhesive layer, which can be attached to the upper edge of the connecting flange on the top surface of the battery 2 to prevent the annular cover 8 from falling off during device transport.

[0084] Understandably, the adhesive layer is double-sided tape, which can be peeled off and replaced.

[0085] In some embodiments, a coupling 11 is fixedly mounted between the lower end of the round rod 4 and the upper output end of the vertical generator 1, and the lower end of the round rod 4 and the upper output end of the vertical generator 1 can be stably connected by the coupling 11.

[0086] In some embodiments, a fixing ring 3 is fixedly sleeved at the lower edge of the outer wall of the battery 2, and an installation through hole is opened on its circumference. The device can be fixed on the outdoor ground by passing a ground plug through the installation through hole on the fixing ring 3.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
