[0002] With urban development, the number of outdoor municipal facilities such as streetlights, traffic lights, and environmental monitoring equipment is constantly increasing, making the demand for a stable and reliable power supply increasingly urgent. Traditional municipal power supply mainly relies on the municipal power grid, but grid power supply suffers from problems such as complex wiring, high costs, and significant susceptibility to grid failures. Especially in remote areas or emergency situations, the inability of the municipal power grid to provide timely coverage or the occurrence of power outages can severely impact the normal operation of municipal facilities. Wind power generation, as a clean and renewable energy source, has broad application prospects. Vertical axis wind turbines, due to their simple structure, low starting wind speed, and insensitivity to wind direction changes, are particularly suitable for application in urban environments.

[0003] Existing equipment is highly sensitive to wind direction and has low power generation efficiency in densely built-up urban environments. It also lacks adequate lightning protection measures, making outdoor equipment susceptible to lightning strikes and resulting in power outages. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low power generation efficiency and insufficient lightning protection in existing devices in urban environments, and to propose an outdoor municipal facility power supply guarantee device based on a vertical axis wind turbine generator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor municipal facility power supply guarantee device based on a vertical axis wind turbine generator set, comprising a base, a column, a mounting groove, and a wind turbine blade assembly. The top of the base is fixedly connected to the column, and the top of the column has a mounting groove. The inner bottom wall of the mounting groove is fixedly connected to the wind turbine blade assembly. The wind turbine blade assembly includes a servo motor fixedly connected to the inner bottom wall of the mounting groove. The top of the servo motor is fixedly connected to a rotating base, and the top of the rotating base is fixedly connected to a fixing frame. Wind turbine blades are fixedly connected to the surface of the fixing frame. The two sides of the wind turbine blades are inwardly curved into an inwardly curved airfoil shape, and turbulence protrusions are fixedly connected to the surface of the wind turbine blades.

[0006] Furthermore, a lightning protection component is fixedly connected to the top of the fixed frame, and the lightning protection component includes a base plate fixedly connected to the top of the fixed frame.

[0007] Furthermore, a lightning rod is fixedly connected to the top of the base plate, and a lightning protection strip is fixedly connected to the top of the base plate.

[0008] Furthermore, a down conductor is fixedly connected to the surface of the lightning strip, and four support frames are fixedly connected to the top of the column.

[0009] Furthermore, the top of the support frame is fixedly connected to the surface of the base plate, and traction rings are fixedly connected to the surfaces of the four support frames.

[0010] Furthermore, the surface of the down conductor is engaged with the inner wall of the traction ring, and the lower end of the down conductor is fixedly connected to the surface of the column.

[0011] Furthermore, a grounding grid is fixedly connected to the bottom of the base, the bottom of the down conductor is fixedly connected to the surface of the grounding grid, and grounding nails are inserted into the surface of the grounding grid.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a wind turbine blade assembly, the servo motor and the rotating base can precisely adjust the rotation angle of the wind turbine blades to adapt to wind direction changes in complex urban environments.

In this utility model, by setting up lightning protection components, the lightning rod adopts early discharge technology, which can actively generate an upward leader when thunderclouds approach, attracting the lightning strike point to itself and protecting the wind turbine blades below from direct lightning damage. The lightning protection strip surrounds the top of the base plate to form a ring-shaped protective area, which, together with the down conductor and grounding grid, constitutes a complete lightning protection grounding system. It can quickly conduct the lightning current into the ground, meeting the lightning protection requirements of outdoor electrical equipment. The four support frames are symmetrically distributed, which not only provide stable support for the base plate, but also the traction rings on their surfaces can fix the down conductor to prevent it from breaking in strong winds.

Detailed Implementation

[0022] Please see Figure 1-5 This utility model provides a technical solution: an outdoor municipal facility power supply guarantee device based on a vertical axis wind turbine generator set, including a base 1, a column 2, a mounting groove 3 and a wind turbine blade assembly 4. The top of the base 1 is fixedly connected to the column 2, the top of the column 2 is provided with a mounting groove 3, and the inner bottom wall of the mounting groove 3 is fixedly connected to the wind turbine blade assembly 4.

[0023] The specific settings and functions of its wind turbine blade assembly 4 and lightning protection assembly 5 will be explained below.

[0024] In this embodiment: the wind turbine blade assembly 4 includes a servo motor 41 fixedly connected to the bottom wall of the mounting groove 3, a rotating base 42 fixedly connected to the top of the servo motor 41, a fixed connecting frame 43 fixedly connected to the top of the rotating base 42, wind turbine blades 44 fixedly connected to the surface of the fixed connecting frame 43, the two sides of the wind turbine blades 44 are inwardly curved into an inwardly curved airfoil shape, and turbulence protrusions 45 are fixedly connected to the surface of the wind turbine blades 44.

[0025] The effects achieved by the above components are as follows: by setting the servo motor 41 and the rotary seat 42, the angle of the wind turbine blades 44 can be adjusted in real time according to the wind direction sensor data, so that it is always in the best windward state. In the complex wind field between urban buildings, the wind energy capture efficiency is improved. The inwardly folded airfoil wind turbine blades 44 can start rotating at low wind speeds, which is suitable for low wind speed scenarios such as urban streets. The turbulence protrusions 45 reduce the eddy current loss caused by air separation by disturbing the airflow boundary layer, thereby improving the aerodynamic efficiency of the wind turbine blades 44.

[0026] Specifically, a lightning protection component 5 is fixedly connected to the top of the fixed frame 43. The lightning protection component 5 includes a base plate 51 fixedly connected to the top of the fixed frame 43.

[0027] The effect achieved by the above components is as follows: by setting the base plate 51, a stable installation foundation is provided for the lightning protection component 5, and its circular structure is adapted to the top of the fixed bracket 43, ensuring the installation stability of the lightning rod 52 and the lightning protection strip 53.

[0028] Specifically, a lightning rod 52 is fixedly connected to the top of the base plate 51, and a lightning protection strip 53 is fixedly connected to the top of the base plate 51.

[0029] The effects achieved by the above components are as follows: by setting the lightning rod 52 with an early discharge structure, when the charge of the thundercloud accumulates, it can actively ionize the surrounding air to form an upward leader, attracting the lightning strike point to itself, protecting the wind turbine blade assembly 4 below from direct lightning strikes. The lightning protection strip 53 surrounds the top of the base plate 51 to form a ring-shaped protective strip, which, together with the lightning rod 52, constitutes a three-dimensional lightning protection network that can intercept lightning discharge and ensure the safety of the equipment in thunderstorm weather.

[0030] Specifically, the surface of the lightning strip 53 is fixedly connected with a down conductor 54, and the top of the column 2 is fixedly connected with four support frames 55.

[0031] The effect achieved by the above components is that by setting the down conductor 54, the lightning current guided by the lightning strip 53 and the lightning rod 52 can be quickly introduced into the grounding grid 57. It has high conductivity and is resistant to oxidation, ensuring the reliability of the lightning protection path.

[0032] Specifically, the top of the support frame 55 is fixedly connected to the surface of the base plate 51, and traction rings 56 are fixedly connected to the surfaces of the four support frames 55.

[0033] The effects achieved by the above components are as follows: by setting the top of the support frame 55 to be fixed to the seat plate 51 with bolts, the connection strength is high, which can ensure that the seat plate 51 is stable and will not fall off. The traction ring 56 is used to hold the down line 54, so that the down line 54 runs neatly and in a standardized manner, while preventing the down line 54 from being worn and broken due to swinging in strong winds.

[0034] Specifically, the surface of the down conductor 54 is snap-fitted to the inner wall of the traction ring 56, and the lower end of the down conductor 54 is fixedly connected to the surface of the column 2.

[0035] The effects achieved by the above components are as follows: by setting the down conductor 54 to be clamped in the traction ring 56, the swing amplitude of the down conductor 54 can be limited, preventing cable fatigue breakage caused by long-term swing. The lower end of the down conductor 54 is fixed to the surface of the column 2 by the wire clamp, ensuring that the lightning current can be smoothly introduced into the grounding grid 57 along the down conductor 54, reducing the grounding impedance.

[0036] Specifically, a grounding grid 57 is fixedly connected to the bottom of the base 1, the bottom of the down conductor 54 is fixedly connected to the surface of the grounding grid 57, and a grounding nail 58 is inserted and connected to the surface of the grounding grid 57.

[0037] The effects achieved by the above components are as follows: by setting up the grounding grid 57, the grounding area can be increased and the grounding resistance can be reduced; the grounding nail 58, through full contact with the soil, ensures that the lightning current can be quickly discharged into the ground, protecting the equipment from lightning damage.

[0038] Working principle: By setting up the wind turbine blade assembly 4, the servo motor 41 and the rotating base 42 can precisely adjust the rotation angle of the wind turbine blades 44 to adapt to wind direction changes in complex urban environments. The inward-curving airfoil design of the wind turbine blades 44 can start at low wind speeds and improve power generation efficiency in the turbulent environment between urban buildings. The turbulence protrusions 45 are evenly distributed on the blade surface, which can disturb the airflow boundary layer, reduce air separation, improve the wind energy utilization rate of the wind turbine blades 44, and meet the stable power supply requirements of street lights and small monitoring equipment. The fixed frame 43 has a wind resistance of level 12 to ensure the safe operation of the equipment in severe weather.

[0039] By setting up lightning protection components 5, the lightning rod 52 adopts early discharge technology, which can actively generate an upward leader when thunderclouds approach, attracting the lightning strike point to itself and protecting the wind turbine blade assembly 4 below from direct lightning damage. The lightning protection strip 53 surrounds the top of the base plate 51 to form a ring-shaped protective area. Together with the down conductor 54 and the grounding grid 57, it forms a complete lightning protection grounding system, which can quickly conduct the lightning current into the ground, meeting the lightning protection requirements of outdoor electrical equipment. The four support frames 55 are symmetrically distributed, which not only provide stable support for the base plate 51, but also the traction rings 56 on their surfaces can fix the down conductor 54 to prevent the down conductor 54 from breaking in strong winds. The grounding nails 58 work with the grounding grid 57 to increase the grounding area, improve the reliability of the lightning protection system, reduce the damage rate of equipment to lightning strikes in thunderstorms, and ensure the continuous and stable power supply of municipal facilities.
