Description

Technical Field

[0001] The present application relates to the technical field of wind power generation, and in particular to a portable vertical wind turbine. Background Art

[0002] Wind power is a clean and renewable energy source that converts wind kinetic energy into electrical energy. There are two main types of wind turbines: horizontal-axis wind turbines, where the blades rotate parallel to the wind direction, and vertical wind turbines, where the blades rotate perpendicular to the wind direction. Vertical wind turbines are less affected by wind direction than horizontal-axis wind turbines, resulting in a simpler overall structure and are commonly used in places with low power generation, such as homes. Existing small wind turbines have a rigid structure, making them difficult to disassemble and transport, and lacking portability. Summary of the Invention

[0003] In order to solve the problem of insufficient portability of small generators in the prior art, the present application provides a portable vertical wind turbine.

[0004] In order to achieve the above objectives, the technical solutions adopted in this application are:

[0005] A portable vertical wind turbine comprises a retractable support column formed by a plurality of movably connected rods, wherein brackets are fixedly mounted near both ends of the support column, and a plurality of blades distributed around the axis of the support column are detachably connected to the brackets, and the two ends of the support column are respectively fixedly connected to a fence; the support column also comprises a power generation component transmission-connected to the blades, and a first storage battery connected to the power generation component.

[0006] The wind turbine in this solution utilizes the retractability of the support column and the detachability between the blades and the support column to improve the portability of the wind turbine. Specifically, when the generator needs to be stored or moved, the blades are removed from the bracket, and then the support column is retracted so that the fences at both ends of the support column are close to each other. When the support column is retracted to the shortest, the two fences are in contact with each other or the gap is small. By maintaining the retracted state of the support column or connecting and fixing the two fences, the wind turbine can be kept fixed as a whole after storage.

[0007] The wind turbine in this solution is a small portable generator and needs to be retractable to make it easy to carry or move. In this solution, the support column of the wind turbine is set to a telescopic structure, and the blades are detachable from the support column through the bracket. When the generator needs to be stored or moved, the blades are first removed from the bracket, and then the support column is retracted so that the fences at both ends of the support column are close to each other. When the support column is retracted to the shortest, the two fences are in contact with each other or the gap is small. By keeping the support column in a retracted state or connecting and fixing the two fences, the wind turbine is kept fixed as a whole after storage.

[0008] Furthermore, the power generation assembly includes a drive shaft drivingly connected to the blade and a generator connected to the drive shaft. A charging and rectifying module is provided between the first storage battery and the generator. An inverter power module is provided at the output end of the first storage battery. A monitoring module is further included for monitoring and visualizing the charge and discharge status of the first storage battery. It should be noted that in the field of clean energy conversion equipment, it is a method well-known to those skilled in the art to provide a rectifier and an inverter between the energy conversion end, the storage battery, and the energy utilization end. Therefore, this application will not elaborate too much on the charging and rectifying module and the inverter power module. This solution further optimizes the circuit of wind power generation, with the focus on the setting of the monitoring module. Through the visualization of the status of the first storage battery, it is convenient for users to determine the power consumption plan.

[0009] Furthermore, a solar power generation panel is provided on the top surface of the upper fence, and a second storage battery connected to the solar power generation panel. The second storage battery supplies power to the monitoring module.

[0010] In this solution, a solar power generation mechanism is also provided, a solar power generation mechanism dedicated to supplying power to the monitoring module. The solar power generation panel is arranged on the top of the wind power generation equipment so that it can receive light as much as possible during the use of the wind turbine, thereby converting solar energy into electrical energy, and storing and discharging electricity through the second storage battery. It should be noted that for those skilled in the art, in addition to a solar power generation panel and a storage battery, a rectifier and a digital inverter, etc. are also required in the circuit setting. The former rectifies the electricity output by the solar power generation panel so that it can charge the storage battery, and the latter enables the current output by the storage battery to supply power to the monitoring module. This is also the prior art in this field.

[0011] Furthermore, the monitoring module includes a monitoring unit for monitoring the charging speed, total power, and discharging speed of the first storage battery, a display unit for displaying the monitoring information, and a data processing unit for converting the results measured by the monitoring unit and transmitting them to the display unit.

[0012] Furthermore, the support column includes at least one set of outer rods and inner rods sleeved inside the outer rods and slidingly engaged therewith. At least one set of mutually adapted chutes and sliding strips are respectively provided along the axial direction on the circumferential surfaces of the inner rods and the outer rods in contact with each other. A flange protrudes circumferentially at the lower end of the inner rod, and a limiting platform protruding inward is provided at the upper end of the outer rod to abut against the top surface of the flange.

[0013] Furthermore, through holes with the same aperture are respectively provided in the radial direction on the lower part of the inner rod and the upper part of the outer rod. The through holes are matched with fasteners to relatively fix the inner rod and the outer rod.

[0014] The beneficial effects of the present application are as follows: Through the telescopic property of the support column and the detachable connection of the blades relative to the support column, the overall power generation device can be stored in a way that reduces the occupied space. At the same time, after storage, the fences at both ends of the support column approach each other to protect the main equipment of the power generation device, facilitating the overall storage, packing, and transportation of the device.

[0028] Example 1:

[0029] like Figures 1-2 The portable vertical wind turbine shown includes a retractable support column 3 formed by a plurality of movably connected rods, with brackets 2 fixedly mounted near both ends of the support column 3, and a plurality of blades 4 distributed around the axis of the support column 3 being detachably connected to the brackets 2, and both ends of the support column 3 being fixedly connected to a fence 1 respectively; it also includes a power generation component transmission-connected to the blades 4, and a first storage battery connected to the power generation component.

[0030] Here’s how it works:

[0031] In this embodiment, the support column 3 of the wind turbine generator is a telescopic structure, and the blades 4 are detachable from the support column 3 via the bracket 2. When the generator needs to be stored or moved, the blades 4 are first removed from the bracket 2, and then the support column 3 is retracted so that the fences 1 at both ends of the support column 3 are close to each other. When the support column 3 is retracted to its shortest position, the two fences 1 touch each other or have a small gap. By maintaining the support column 3 in the retracted state or connecting and fixing the two fences 1, the wind turbine generator is kept in a fixed position after storage. It should be noted that the blades 4 in this application also serve to maintain the support column 3. When the blades 4 of fixed length are installed on the bracket 2, the contraction of the support group is limited. Therefore, the tightening force required for the fixing structure between the rods constituting the support column 3 is relatively low. However, to prevent the blades 4 from being deformed by excessive vertical force and affecting kinetic energy conversion, a simple fixing structure can be used between the rods. It is worth noting that the generator set in this application is a mechanism in wind power generation technology that converts the kinetic energy of the blades 4 into usable electrical energy. This is a prior art well known to those skilled in the art and will not be described in detail in this application.

[0032] Example 2:

[0033] This embodiment is further optimized and limited based on the embodiment 1.

[0034] The power generation assembly includes a drive shaft connected to the blades 4 and a generator connected to the drive shaft. A charging rectifier module is provided between the first battery and the generator. An inverter module is provided at the output end of the first battery. A monitoring module is also provided for monitoring and visualizing the charge and discharge status of the first battery. A solar panel 5 is provided on the top surface of the upper fence 1, along with a second battery connected to the solar panel 5. The second battery provides power to the monitoring module.

[0035] In this embodiment, a monitoring module is set in the generator set to realize real-time monitoring of the status of the first battery and visualization of the monitoring results, so as to facilitate the user to determine a reasonable power usage plan according to the status of the first battery. At the same time, in this embodiment, solar energy is converted into electrical energy to power the monitoring module separately, so that a set of wind power generation mechanisms is dedicated to powering users and can ensure continuous monitoring of the status of the first battery in no wind conditions.

[0036] Further in this embodiment, an example of a monitoring module is provided to determine the visualization data type for the user. The monitoring module includes a monitoring unit for monitoring the charging speed, total power, and discharging speed of the first storage battery, a display unit for displaying the monitoring information, and a data processing unit for converting the results measured by the monitoring unit and transmitting them to the display unit. It should be noted that the monitoring of the state of the first storage battery is a continuous process. Especially when the first storage battery is not in the charging state due to insufficient wind power, due to the visualization of the detection results, the display unit still consumes power continuously. Therefore, whether the discharging of the first storage battery continues varies according to the user's usage, but the discharging of the second storage battery is continuous. Therefore, in this application, using the second storage battery to supply power to the monitoring module avoids the rapid battery aging caused by the first storage battery directly supplying power for too long a continuous working time. Since the power required to maintain the operation of the monitoring module is extremely low and the cost of the small solar power generation module is relatively low, setting the second storage battery has little impact on the total cost of the wind power generation equipment in this application, but can achieve the purpose of significantly improving the effective service life of the first storage battery.

[0037] Embodiment 3:

[0038] Since the bracket 2 is installed on different rods of the support column 3, and in order to ensure the balanced force on the blade 4, the relative positions (including factors such as angle and distance) between the two brackets 2 should be kept fixed, while the rods for installing the bracket 2 are relatively movable. Therefore, in order to keep the total length of the support column 3 consistent each time it extends to the working state and the angle between the rods fixed, the connection method between the rods is further optimized and defined. On the basis of Embodiment 1, in this embodiment, as Figures 3-5 shown, the support column 3 includes at least one set of outer rods 301 and inner rods 302 sleeved inside the outer rods 301 and slidably matched with them. On the circumferential surfaces where the inner rods 302 and the outer rods 301 are in contact, at least one set of mutually adapted chutes 3012 and sliding strips 3022 are respectively arranged along the axial direction. The lower end of the inner rod 302 protrudes circumferentially to form a flange 3021, and the upper end of the outer rod 301 protrudes inwards to form a limiting platform 3011 that abuts against the top surface of the flange 3021. In this embodiment, the cooperation between the sliding strip 3022 and the chute 3012 ensures that the inner rod 302 does not rotate circumferentially relative to the outer rod 301 during sliding, so that only the distance between the two brackets 2 on the support column 3 changes. The cooperation between the flange 3021 and the limiting platform 3011 ensures that the elongation amount of the support column 3 is the same each time it is retracted and reused.

[0039] Preferably, in this embodiment, an example of a structure for keeping the inner rod member 302 and the outer rod member 301 fixed is provided. Through holes with the same aperture are respectively provided in the radial direction at the lower part of the inner rod member 302 and the upper part of the outer rod member 301. The through holes are matched with fasteners to relatively fix the inner rod member 302 and the outer rod member 301. In this embodiment, through holes are respectively provided in the inner rod member 302 and the outer rod member 301. When the support column 3 extends, the through holes in the inner rod member 302 and the outer rod member 301 coincide. At this time, when the fastener passes through the holes at the same time, the relative positions of the inner rod member 302 and the outer rod member 301 in the axial direction can be kept unchanged, that is, the length of the support column 3 remains unchanged. An example of a fastener is provided. The fastener is a threaded rod. The threaded rod is simultaneously matched with the through holes in the inner rod member 302 and the outer rod member 301. Nuts are screwed into both ends of the threaded rod, and the surfaces of the nuts are tightly attached to the surface of the outer rod member 301, so as to realize the fixation between the outer rod member 301 and the inner rod member 302.

[0040] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
