Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and specifically to a vertical axis wind-powered street light with a brake locking function. Background Technology

[0002] Wind energy, as a clean and renewable energy source, is widely used in street lighting applications. Wind-powered streetlights can achieve on-site wind energy conversion, energy storage, and solar power supply, resulting in energy conservation and environmental protection. However, existing vertical-axis wind-powered streetlights mostly have fixed blade structures, meaning their windward area cannot be adjusted. At low wind speeds, the blades have a small wind-receiving area, making starting difficult and resulting in low power generation efficiency. In strong winds, the impeller is prone to overspeeding, which can damage the generator and transmission components, or even cause tipping accidents.

[0003] Some adjustable-blade wind turbine structures suffer from problems such as independent adjustment drive and braking structures, poor linkage, lack of reliable mechanical locking in the event of power failure, and weak wind resistance. Furthermore, conventional wind turbines lack intelligent wind speed matching and control, failing to adaptively adjust blade deployment based on real-time wind speed. This makes it difficult to balance power generation stability and overall machine safety, hindering their ability to meet the long-term reliable use requirements of outdoor roads. Therefore, there is an urgent need to design a vertical axis wind-powered street light with adaptively adjustable windward area and linked mechanical locking protection. Summary of the Invention

[0004] This invention aims to solve the technical problems of low power generation efficiency, easy damage from strong winds, lack of reliable mechanical locking protection, and insufficient intelligence in existing fixed-blade vertical axis wind power streetlights. It provides a vertical axis wind power streetlight with a braking and locking function, which can adaptively adjust the windward area of ​​the blades according to the wind speed, combining power generation efficiency and strong wind safety protection, and has a mechanical linkage locking structure with high reliability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vertical axis wind power street light with a brake locking function, comprising a light pole, a light frame, a light head, and a vertical axis wind turbine generator set; the light frame is installed at the top of the light pole, the light head is installed at the end of the light frame, and the vertical axis wind turbine generator set is installed above the light frame; The vertical axis wind turbine generator set includes a connecting base, a bracket is mounted on the top of the connecting base, a main shaft is rotatably connected to the top of the bracket, a fixing block is fixedly connected to the top of the main shaft, and a sliding ring is slidably connected to the middle of the main shaft; the fixing block and the sliding ring are fixedly connected to blades via cross telescopic rods, the number of blades is three, and the cross telescopic rods are X-shaped cross shafts; The inner side of the blade is provided with a sliding groove, and a sliding block is slidably connected to the sliding groove. The top end of the outer side of the cross telescopic rod is hinged to the sliding block, and the bottom end of the outer side of the cross telescopic rod is hinged to the blade. The top end of the inner side of the cross telescopic rod is hinged to the fixed block, and the bottom end of the inner side of the cross telescopic rod is hinged to the sliding ring. The sliding ring is connected to the main shaft through a spline drive. A generator is installed inside the bracket, and the bottom end of the main shaft is connected to the rotating shaft of the generator for transmission. An electric telescopic rod is installed at the top of the bracket, and a rotating ring is fixedly connected to the top of the electric telescopic rod. The rotating ring is rotatably connected to the bottom end of the sliding ring. A locking disc is installed in the middle of the bottom end of the spindle, and a locking groove is opened at the bottom end of the locking disc; The electric telescopic rod has a rack on one side, and a gear is rotatably connected to the top side of the bracket. A fixing sleeve is fixedly connected inside the bracket, and an L-shaped locking rod is slidably connected to the fixing sleeve. The bottom end of the locking rod is adapted to the locking groove. A toothed rod is slidably connected to one side of the top of the bracket, and both the toothed rod and the rack are meshed with the gear; a sliding sleeve is installed at the bottom of the toothed rod, and the sliding sleeve and the top of the locking rod are elastically connected by a spring; The gear is provided with a dustproof shell on its outer side; a stop is provided at the top of the locking groove; a limit ring is provided at the bottom of the sliding sleeve; and the spring is assembled between the top of the limit ring and the top of the stop. The bottom of the lamp post is equipped with a controller and an energy storage battery, and the top of the lamp holder is equipped with a wind speed sensor. The vertical axis wind turbine generator and the lamp head are electrically connected to the energy storage battery. The electric telescopic pole and the wind speed sensor are electrically connected to the controller. The energy storage battery is electrically connected to the external power grid.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Adaptive pitch control for high power generation efficiency: Real-time wind speed is collected by a wind speed sensor, and the controller controls the extension and retraction of the electric telescopic rod, which drives the sliding ring to slide along the main shaft axis. In conjunction with the X-shaped cross telescopic rod, the blades are pushed and pulled to automatically change the windward area of ​​the blades. At low wind speeds, the blades are extended to increase the windward surface area and improve start-up and power generation efficiency, while at high wind speeds, they are retracted to reduce the windward surface area and limit the impeller speed.

[0007] 2. Linked mechanical locking, reliable protection against strong winds: When the electric telescopic pole extends or retracts, it uses a rack, pinion, and toothed linkage to drive the spring-driven locking rod into the locking groove of the locking disc, thus achieving mechanical locking of the main shaft. Even in the event of electrical control failure or extreme winds, it can still reliably brake, preventing the fan from running away or components from being damaged, and improving the overall wind resistance safety level of the machine.

[0008] 3. Stable transmission and durable structure: The sliding ring and main shaft spline transmission ensure torque transmission; the sliding groove and sliding block cooperate to guide, and the blade adjustment is smooth; the gear is encased in a dustproof shell, which has strong outdoor weather resistance and extends service life.

[0018] Please see Figure 1-3 This invention provides a technical solution for a vertical axis wind-powered street light with a brake locking function: A vertical axis wind-powered street light with a brake locking function includes a light pole 1, a light frame 2, a light head 3, and a vertical axis wind turbine generator set 4. The light frame 2 is fixedly installed at the top of the light pole 1, the light head 3 is assembled at the end of the light frame 2, and the vertical axis wind turbine generator set 4 is mounted on top of the light frame 2. The overall layout is compact and suitable for road installation.

[0019] The vertical axis wind turbine generator set 4 includes a connecting seat 12, with a bracket 11 fixedly connected to the top of the connecting seat 12. The main shaft 21 is rotatably mounted on the top of the bracket 11. Three sets of X-shaped cross telescopic rods 7 are arranged between the top fixing block 22 and the middle sliding ring 8 of the main shaft 21. Each set of cross telescopic rods 7 is connected to a blade 6 on the outside. The blade 6 is provided with a sliding groove 5 and a sliding block on the inside. The ends of the cross telescopic rods 7 are hinged to the corresponding sliding block, blade 6, fixing block 22, and sliding ring 8. The sliding ring 8 is splined to the main shaft 21, which can slide axially and transmit torque synchronously.

[0020] The bracket 11 has a built-in generator 13. The bottom end of the main shaft 21 is connected to the input shaft of the generator 13. The impeller rotation drives the generator to generate electricity. An electric telescopic rod 10 is installed on the top of the bracket 11. The telescopic end of the electric telescopic rod 10 is rotatably connected to the bottom end of the sliding ring 8 via a rotating ring 9. The telescopic movement can push and pull the sliding ring to move axially, realizing the opening / closing of the cross telescopic rod 7, and adjusting the outer diameter and windward area of ​​the three blades 6.

[0021] The main shaft 21 has a locking disc 14 at its bottom, with a locking groove 15 at its bottom. The electric telescopic rod 10 has a rack, and the gear 20 on the bracket 11 simultaneously meshes with the rack and the rack 19. The lower end of the rack 19 is connected to a sliding sleeve 18, which is connected to an L-shaped locking rod 23 via a spring 16. The locking rod 23 is slidably positioned within the fixed sleeve 17 and can be inserted downwards into the locking groove 15 to lock the main shaft 21. A dustproof shell is installed on the outside of the gear 20 to prevent mud, sand, and rainwater from entering outdoors. The locking groove 15 stop and the sliding sleeve 18 limit ring are fitted to the spring 16 to ensure stable elastic transmission.

[0022] The bottom of the light pole 1 integrates a controller and energy storage battery, and the top of the light frame 2 is equipped with a wind speed sensor; the vertical axis wind turbine generator 4 and the light head 3 are electrically connected to the energy storage battery, and the wind speed sensor and the electric telescopic pole 10 are signal connected to the controller. The energy storage battery is connected to the external power grid for supplementary power / surplus power is fed into the grid.

[0023] Working process: Under normal low wind speed conditions, the wind speed sensor collects signals and transmits them to the controller. The controller controls the electric telescopic rod 10 to extend, pushes the sliding ring 8 to move upward, the X-shaped cross telescopic rod 7 to open, the blades 6 to unfold outward, increasing the windward area, the wind energy drives the blades to rotate the main shaft 21, the generator 13 generates electricity and stores it in the energy storage battery to power the lamp head 3 at night; When the detected strong wind exceeds the standard, the controller controls the electric telescopic rod 10 to retract, pulling the sliding ring 8 downward, the cross telescopic rod 7 to close, and the blades 6 to retract inward to reduce the windward area and reduce the impeller speed; at the same time, the retraction of the electric telescopic rod 10 drives the rack and pinion gear 20 and the rack 19 to move downward, compressing the spring 16 to push the locking rod 23 into the locking groove 15 of the locking disc 14, mechanically locking the main shaft 21, stopping the entire machine and braking it to avoid damage from overspeed; Once the wind speed returns to a safe range, the controller resets the electric telescopic pole, the locking rod disengages from the locking groove, the main shaft is unlocked, and the unit resumes normal power generation. In the absence of wind power, the energy storage battery or external power grid ensures continuous power supply for lighting.

[0024] The above description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations to these embodiments within the spirit and principles of the present invention, achieved through conventional substitutions or by achieving the same function without departing from the principles and spirit of the present invention, fall within the scope of protection of the present invention.
