TECHNICAL FIELD

[0001] The utility model belongs to the field of channel navigation mark, especially relates to a vertical wind power generation buoy. BACKGROUND

[0002] At present, the power supply mode applied to the channel navigation mark of the Yangtze River only has solar power generation, is relatively single, and the energy system reliability is relatively low.

[0003] With the increasing informationization and intelligentization of the channel, more and more equipment terminals are carried on the buoy and the power consumption is larger and larger. The solar power supply is greatly influenced by the light intensity, illumination time and solar panel cleanliness, and the battery is often discharged and the equipment terminal works due to the fact that the charging power is less than the consumption power. In order to solve the above problems, a wind power generation is designed to supplement the power demand of the navigation terminal equipment without changing the channel indication function of the buoy body.

[0004] The power supply mode of the buoy is mostly solar power generation, and the mode is single. The mountains on both sides of the river above the Three Gorges block most sunlight in the daytime, which influences the solar power generation efficiency. Moreover, the single solar power generation occupies a large deck area, influences the personnel operation and has limited development space. In addition, with the increasing intelligentization of the buoy, the power consumption is larger and larger, and the single solar power generation cannot meet the demand. The terrain is suitable for wind power generation for the buoy. SUMMARY

[0005] The utility model solves the technical problem that a vertical wind power generation buoy is provided. The buoy combines wind power generation with the buoy function, solves the problems of low reliability, great influence of light and insufficient power supply capacity of the single solar power supply of the traditional navigation mark, supplements the electric energy by using wind energy, meets the equipment power demand, and does not occupy the deck plane space, which is convenient for personnel operation.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme:

[0007] A vertical wind power generation buoy, comprising a support outer frame, the surface of the support outer frame is used for setting a channel navigation mark, a wind blade rotating assembly is rotatably installed on the inner side of the support outer frame, the wind blade rotating assembly is in rotating cooperation with the rotor of a generator, and the stator of the generator is electrically connected with a power storage device.

[0008] Preferably, the support outer frame is a tri-prism structure connected by a plurality of strip-shaped rods, bearing seats are respectively arranged at the top and bottom of the support outer frame, and the bearing seats are connected with the central shaft rod of the wind blade rotating assembly.

[0009] Preferably, a plurality of triangular blades are arranged on the central shaft rod of the wind blade rotating assembly, and the plurality of triangular blades are annularly arranged around the central shaft rod.

[0010] Preferably, a plurality of triangular identification plates are arranged on the support outer frame.

[0011] The edge of the triangular identification plate is matched with the edge of the triangular blade, and a gap is left between the edge of the triangular identification plate and the edge of the triangular blade.

[0012] Preferably, the support outer frame is a cylindrical structure connected by a strip-shaped rod and a ring-shaped plate, and a bearing seat is arranged at the top and the bottom of the support outer frame, and the bearing seat is connected with the central shaft rod of the fan blade rotating assembly.

[0013] Preferably, a plurality of spiral blades are arranged on the central shaft rod of the fan blade rotating assembly.

[0014] Preferably, a support foot is arranged at the bottom of the support outer frame, and the support foot is used for being mounted on the ship body.

[0015] Preferably, the generator and the power storage device are mounted at the bottom of the support outer frame.

[0016] The utility model can achieve the following beneficial effects:

[0017] 1. Break through the limitation of traditional single solar power supply of Yangtze River channel navigation mark, and introduce wind power generation mode. In the area above the Three Gorges, the light is easily blocked by the mountain, and the solar power generation is limited. The local large wind power resource is used for power generation, the solar energy and the wind energy are complementarily powered, the problems such as that the charging power is lower than the consumption power, the battery is power shortage, and the equipment terminal cannot normally work due to insufficient illumination are effectively solved, the stability and the reliability of energy system are obviously improved, and the continuous and stable operation of navigation mark equipment is ensured.

[0018] 2. Compared with the condition that the traditional single solar power generation needs to occupy a large deck area, the vertical wind power generation buoy fully utilizes the vertical space of the buoy for the integrated design of the wind power generation device. The wind power generation assembly is installed in the inside of the support outer frame, does not additionally occupy the deck plane space, reduces the influence on the personnel operation area, provides wider operation space for the staff, facilitates the development of daily maintenance and repair work, and also reserves sufficient development space for the future loading of more intelligent equipment on the buoy.
