Description

Technical Field

[0001] The present invention relates to the technical field of outdoor municipal facility power supply, and in particular to outdoor municipal facility power supply guarantee equipment based on a vertical axis wind turbine generator set. Background Art

[0002] With urban development, the number of outdoor municipal facilities such as streetlights, traffic lights, and environmental monitoring equipment continues to increase, creating an increasingly urgent need for a stable and reliable power supply. Traditional municipal facilities rely primarily on the mains power grid, but this power supply presents challenges such as complex wiring, high costs, and significant susceptibility to grid failures. This is particularly true in remote areas or emergency situations where the mains power supply is unable to reach the facility in a timely manner or a power outage occurs, severely impacting the normal operation of municipal facilities. As a clean, renewable energy source, wind power generation offers broad application prospects. Vertical-axis wind turbines are particularly well-suited for use in urban environments due to their simple structure, low starting wind speed, and insensitivity to wind direction changes.

[0003] Existing devices have high requirements for wind direction and low power generation efficiency in densely populated urban environments; existing devices lack comprehensive lightning protection measures, and outdoor equipment is easily damaged by lightning, resulting in power outages. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems of low power generation efficiency and insufficient lightning protection of existing devices in urban environments, and to propose outdoor municipal facility power supply protection equipment based on vertical axis wind turbines.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: outdoor municipal facility power supply guarantee equipment based on a vertical axis wind turbine generator set, including a base, a column, a mounting slot and a wind fan blade assembly, the top of the base is fixedly connected to the column, the top of the column is provided with a mounting slot, the inner bottom wall of the mounting slot is fixedly connected to the wind fan blade assembly, the wind fan blade assembly includes a servo motor fixedly connected to the inner bottom wall of the mounting slot, the top of the servo motor is fixedly connected to a swivel seat, the top of the swivel seat is fixedly connected to a fixed connecting frame, the surface of the fixed connecting frame is fixedly connected to a wind wheel blade, the two sides of the wind wheel blade are inwardly buckled to form an inward-buckling airfoil, and the surface of the wind wheel blade is fixedly connected to a spoiler protrusion.

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

[0007] Furthermore, a lightning rod is fixedly connected to the top of the base plate, and a lightning 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 termination strip, and four support frames are fixedly connected to the top of the column.

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

[0010] Furthermore, the surface of the down conductor is connected to the inner wall of the traction ring by a clamping connection, and the lower end of the down conductor is fixedly connected to the surface of the column.

[0011] Furthermore, the bottom of the base is fixedly connected to a grounding grid, the bottom of the down conductor is fixedly connected to the surface of the grounding grid, and the surface of the grounding grid is plugged with ground spikes.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In the present invention, by setting a wind fan blade assembly, the servo motor and the swivel seat can accurately adjust the rotation angle of the wind rotor blades to adapt to the changes in wind direction in complex urban environments. The inward-facing airfoil-shaped wind rotor blade design can be started at low wind speeds, which improves the power generation efficiency in the turbulent environment between urban buildings. The spoiler protrusions are evenly distributed on the blade surface, which can disrupt the airflow boundary layer, reduce air separation, and improve the wind energy utilization rate of the wind rotor blades, meeting the stable power supply needs of street lights and small monitoring equipment. The fixed connecting frame has a first-class wind resistance to ensure the safe operation of the equipment in severe weather.

[0014] 2. In the present invention, by setting up lightning protection components, the lightning rod adopts early discharge technology, which can actively generate an upward leader when the thundercloud approaches, attract the lightning strike point to itself, and protect the wind fan blade components below from damage caused by direct lightning. The lightning conductor surrounds the top of the base plate to form an annular protection area, and cooperates with the down conductor and the grounding grid to form a complete lightning protection and grounding system, which can quickly conduct lightning current into the ground to meet the lightning protection requirements of outdoor electrical equipment. The four support frames are symmetrically distributed, which not only provides stable support for the base plate, but also the traction ring on its surface can fix the down conductor to prevent the down conductor from breaking in strong winds. The ground nails cooperate with the grounding grid to increase the grounding area, improve the reliability of the lightning protection system, reduce the lightning damage rate of equipment in thunderstorms, and ensure continuous and stable power supply to municipal facilities.

DETAILED DESCRIPTION

[0022] See also Figure 1-5 The present invention provides a technical solution: an outdoor municipal facility power supply guarantee device based on a vertical axis wind turbine generator set, comprising a base 1, a column 2, a mounting groove 3 and a wind fan 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 fan blade assembly 4.

[0023] The following describes in detail the specific configuration and function of the wind fan blade assembly 4 and the lightning protection assembly 5.

[0024] In this embodiment: the wind fan blade assembly 4 includes a servo motor 41 fixedly connected to the inner bottom wall of the mounting groove 3, the top of the servo motor 41 is fixedly connected to a swivel seat 42, the top of the swivel seat 42 is fixedly connected to a fixed connecting frame 43, the surface of the fixed connecting frame 43 is fixedly connected to a wind wheel blade 44, the two sides of the wind wheel blade 44 are inwardly buckled to form an inward-buckling airfoil shape, and the surface of the wind wheel blade 44 is fixedly connected to a spoiler protrusion 45.

[0025] The effect achieved by the above components is: by setting the servo motor 41 and the rotating seat 42, the angle of the wind rotor blade 44 can be adjusted in real time according to the wind direction sensor data, so that it is always in the best windward state, and in the complex wind field between urban buildings, the wind energy capture efficiency is improved. The inward-facing airfoil-shaped wind rotor blade 44 can start rotating at low wind speeds, which is suitable for scenes with low wind speeds such as urban streets. The spoiler protrusion 45 reduces the eddy loss caused by air separation by disrupting the airflow boundary layer, thereby improving the aerodynamic efficiency of the wind rotor blade 44.

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

[0027] The effect achieved by the above components is: 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 connecting frame 43 to ensure the installation stability of the lightning rod 52 and the lightning strip 53.

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

[0029] The effect achieved by the above components is: by setting the discharge point lightning rod 52 with an early discharge structure, when the thundercloud charge accumulates, it can actively ionize the surrounding air to form an upward leader, attracting the lightning strike point to itself, and protecting the wind fan blade assembly 4 below from direct lightning strikes. The lightning conductor 53 surrounds the top of the base plate 51 to form an annular protective belt, and cooperates with the discharge point lightning rod 52 to form a three-dimensional lightning protection network, which can intercept lightning discharge and ensure the safety of the equipment in thunderstorms.

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

[0031] The effect achieved by the above components is: 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, which has high conductivity and anti-oxidation, ensuring the reliability of the lightning protection path.

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

[0033] The effects achieved by the above components are: by setting the top of the support frame 55 and fixing it to the base plate 51 through bolts, the connection strength is high, which can ensure that the base plate 51 is stable and does not fall off; the traction ring 56 is used to clamp the down conductor 54, so that the routing of the down conductor 54 is neat and standardized, and at the same time prevents the down conductor 54 from being worn and broken due to swinging in strong winds.

[0034] Specifically, the surface of the down conductor 54 is connected to the inner wall of the traction ring 56 by a clamping connection, and the lower end of the down conductor 54 is fixedly connected to the surface of the column 2.

[0035] The effect achieved by the above components is: 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 to prevent cable fatigue breakage caused by long-term swinging. The lower end of the down conductor 54 is fixed to the surface of the column 2 by a wire clamp, ensuring that the lightning current can be smoothly introduced into the grounding grid 57 along the down conductor 54, thereby reducing the grounding impedance.

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

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

[0038] Working Principle: By setting up the wind fan blade assembly 4, the servo motor 41 and the rotating base 42 can cooperate to accurately adjust the rotation angle of the wind rotor blade 44 to adapt to the changes in wind direction in complex urban environments. The inward-facing airfoil-shaped wind rotor blade 44 can be started at low wind speeds, improving power generation efficiency in the turbulent environment between urban buildings. The spoiler protrusions 45 are evenly distributed on the blade surface, which can disrupt the airflow boundary layer, reduce air separation, and improve the wind energy utilization rate of the wind rotor blade 44, meeting the stable power supply requirements of street lights and small monitoring equipment. The fixed bracket 43 has a 12-level wind resistance capability to ensure the safe operation of the equipment in severe weather.

[0039] By setting up the lightning protection component 5, the lightning rod 52 adopts the early discharge technology, which can actively generate an upward leader when the thundercloud approaches, attract the lightning strike point to itself, and protect the wind fan blade component 4 below from being damaged by direct lightning. The lightning conductor 53 surrounds the top of the base plate 51 to form an annular protection area, and cooperates with the down conductor 54 and the grounding grid 57 to form a complete lightning protection and grounding system, which can quickly conduct lightning current into the ground to meet the lightning protection requirements of outdoor electrical equipment. The four support frames 55 are symmetrically distributed, not only providing stable support for the base plate 51, but also the traction ring 56 on its surface can fix the down conductor 54 to prevent the down conductor 54 from breaking in strong winds. The ground nails 58 cooperate with the grounding grid 57 to increase the grounding area, improve the reliability of the lightning protection system, reduce the lightning damage rate of equipment in thunderstorms, and ensure the continuous and stable power supply of municipal facilities.
