Description

Technical Field

[0001] The utility model relates to a wind-solar complementary power generation street lamp. Background Art

[0002] Traditional streetlights utilize low-voltage power transmission networks. These drawbacks, such as long lines, complex wiring and burial, and land consumption, along with significant labor and material resources required for maintenance and inspection, have long been a major challenge. Therefore, the search for energy-saving, environmentally friendly, and highly automated lighting equipment is a top priority. Wind-solar hybrid streetlight systems, as a clean, renewable energy source, are gaining increasing attention.

[0003] Wind-solar hybrid streetlights generate electricity using both sunlight and wind power during the day and from wind turbines at night, compensating for the intermittent imbalance and instability of independent wind and solar energy systems and making the power supply system more stable and reliable. During operation, batteries supply power to the loads. The streetlights require no manual on / off control; an intelligent controller automatically controls the time and brightness of the light.

[0004] Chinese patent publications CN218237276U and CN214038214U both disclose a wind-solar hybrid streetlight. Both utilize a single horizontal-axis wind turbine. However, most horizontal-axis wind turbines require constant adjustment of their blades as wind direction changes, making them susceptible to the effects of terrain and other elements. Furthermore, the use of a single wind turbine results in inefficient wind power generation. This resulted in the need for improvements to address these technical issues, leading to the present invention. Utility Model Content

[0024] like Figures 1 to 6 As shown, the utility model is a wind-solar hybrid power generation street lamp, comprising a lamp pole 2 vertically arranged on a base 1, on which a wind power generation component 3, a lighting component 4, and a solar panel 5 are arranged. The lighting component, solar panel, and wind power generation component are arranged in sequence from top to bottom. This part of the structure is the same as the wind-solar hybrid street lamp in the prior art. The specific improvement is that the wind power generation component 3 includes a pair of windmill housings 6, which are symmetrically distributed on the left and right sides of the upper middle part of the lamp pole 2. Each windmill housing 6 is provided with a blade assembly 7, and the rotation axis of the blade assembly 7 is arranged vertically, that is, the blade assembly is of a vertical axis type. The wind power generation component uses two vertical axis blade assemblies in combination to effectively improve the efficiency of wind power generation. At the same time, the vertical axis blade assembly does not need to adjust its direction as the wind direction changes, and is easy to use.

[0025] In this embodiment, the cross section of the windmill housing 6 is arc-shaped, the windmill housing is arranged vertically, and the arc openings of a pair of windmill housings 6 are arranged opposite to each other, and the arc openings of the windmill housings are facing away from the lamp pole.

[0026] In this embodiment, the blade assembly 7 includes a vertically arranged driving shaft 8 and three vertical blades 9 circumferentially evenly distributed on the outer peripheral side of the driving shaft 8. The driving shaft 8 is coaxially distributed with the windmill housing 6. The driving shaft 8 is fixed with three horizontally arranged blade brackets 10 at intervals from top to bottom. The blade bracket is in the shape of a three-piece impeller. The blade bracket 10 is located on the inner side of the three vertical blades 9. The circumferential side of each blade bracket 10 is fixedly connected to the three vertical blades 9 respectively, so that the three vertical blades are connected to the driving shaft as a whole through the blade bracket; the lower end of the driving shaft 8 passes through the bottom of the windmill housing 6 and is connected to the generator 11.

[0027] In this embodiment, in order to improve the structural strength, a mounting rod 12 is fixed between the tops of a pair of windmill housings 6. The upper end of the driving shaft 8 is rotatably set on the mounting rod 12 via a bearing, and the lower end of the driving shaft 8 is rotatably matched with the bottom of the windmill housing 6 via a bearing.

[0028] In this embodiment, wind-fixing wings 13 are respectively provided at both ends of the mounting rod 12 .

[0029] In this embodiment, adjacent ends of a pair of windmill housings 6 are each provided with a plurality of ventilation holes 14 evenly spaced vertically, and the ventilation holes 14 pass through the windmill housing 6 in a radial direction.

[0030] In this embodiment, in order to improve the structural strength, a plurality of vertically distributed connecting plates 15 are fixed between a pair of windmill housings 6 , and the connecting plates 15 are provided with long slots 16 for the lamp poles 2 to pass through.

[0031] In this embodiment, a bracket 17 installed on the outer wall of the lamp pole 2 is provided above the wind power generation component 3, and a right triangle structure is formed between the bracket 17 and the lamp pole 2. The solar panel 5 is installed at the end of the horizontal side of the bracket 17 away from the lamp pole.

[0032] Further, such as Figure 6 As shown, an adjustment assembly 18 is provided at the end of the bracket 17 away from the lamp pole 2. The adjustment assembly 18 includes an adjustment support 19 fixed to the bracket 17. A vertical servo 20 is mounted on the adjustment support 19.

The servo support 21 is mounted with a horizontal servo 22. The output shaft of the horizontal servo 22 is horizontal and connected to a U-shaped connecting base 23. The solar panel 5 is mounted on the connecting base 23. During operation, the vertical servo drives the horizontal servo to rotate horizontally via the servo support, and the horizontal servo drives the solar panel to rotate via the connecting base, completing pitch adjustment. This facilitates adjusting the position of the solar panel so that the solar panel is perpendicular to the light and achieves the highest utilization rate.

[0033] In this embodiment, the lighting assembly 4 includes a lampshade 24 located above the bracket 17. The lampshade 24 and the bracket 17 are distributed on two opposite sides of the lamp pole 2.

This part of the structure is the same as the wind-solar complementary street lamp in the existing technology, and will not be repeated here.

[0035] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integrated molding process).

[0036] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.
