Description

Technical Field

[0002] A lightning rod, also known as a lightning arrester, is a device used to protect buildings, tall trees, and other structures from lightning strikes. A lightning arrester is installed at the top of the protected object and connected to an underground grounding network using a compliant conductor. Lightning rod specifications must conform to GB standards, and the required height varies for each lightning protection category. When a thundercloud discharges near the ground, it distorts the ground's electric field. At the top of the lightning rod, a localized electric field concentration is formed, influencing the development direction of the lightning leader discharge and guiding the lightning to the rod. The lightning current is then conducted to the ground through the grounding down conductor and grounding device, thus protecting the object from lightning strikes. With the rapid development of China's construction industry, lightning protection equipment has also entered a period of rapid development, with significant advancements in the types, quality, and functions of lightning rods.

Detailed Implementation

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides a lightning protection energy storage device for buildings, such as... Figure 1-14As shown, the building lightning protection energy storage device includes: a mounting base 1, a photovoltaic power generation panel 9, and a lightning arrester main rod 10; a support column 2 is fixedly installed on the top of the mounting base 1, a claw frame 3 is fixedly installed on the top of the support column 2, a support disc 4 is fixedly installed on the top of the claw frame 3, a support cylinder 5 is fixedly nested at the center of the support disc 4, a support seat 6 is fixedly installed on the top of the support cylinder 5, the support seat 6 is made of conductive material, an assembly cylinder 7 is rotatably sleeved on the support seat 6, and an assembly ring 8 is fixedly sleeved on the assembly cylinder 7; the support disc 4, support cylinder 5, assembly cylinder 7, and assembly ring 8 are all made of insulating material; the photovoltaic power generation panel 9 is located on the top of the assembly ring 8, and its setting... Positioned in accordance with the direction of sunlight, the support base 6 is equipped with an auxiliary battery pack 33, which is connected to the photovoltaic panel 9 for storing electrical energy. The main lightning arrester 10 is fixedly installed at the top center of the support base 6. Multiple auxiliary needles 11 are also fixedly installed on the support base 6, which surround the main lightning arrester 10. Both the main lightning arrester 10 and the auxiliary needles 11 are made of conductive material and are used to attract lightning. A conductive head 12 is fixedly embedded inside the support base 6. A grounding wire 13 extending to the outside is connected to the conductive head 12. The grounding wire 13 passes through the support cylinder 5, and one end of the grounding wire 13 is connected to a grounding seat 14 for conducting lightning to the ground.

[0020] In this embodiment, the mounting base 1 is fixed to a concrete pier or steel beam on the roof of a high-rise building, keeping the support column 2 vertical. Then, the grounding base 14 is welded to the building's main grounding grid, forming a continuous discharge channel. Under normal conditions, the photovoltaic panel 9 rotates around the horizontal axis of the support base 6 along with the assembly ring 8. Direct current generated in the direction of sunlight is sent to the auxiliary battery pack 33 for real-time storage via internal wires. When a thundercloud approaches, the main lightning arrester 10 and multiple auxiliary arresters 11 together form a three-dimensional lightning field, preferentially capturing the downward leader. The lightning current is discharged to the ground sequentially through the conductive head 12, the grounding wire 13, and the grounding base 14, completing the lightning protection. Throughout the process, the support disc 4, support cylinder 5, assembly cylinder 7, and assembly ring 8, made of insulating material, completely isolate the photovoltaic and energy storage circuits from high potentials, ensuring that the auxiliary battery pack 33 and subsequent electrical equipment are not subjected to instantaneous overvoltage impacts.

[0021] The support base 6, as the sole conductive node, physically separates the "lightning attraction" and "power consumption" channels: its top protrudes from the roof, providing equipotential bonding for the main lightning rod 10 and auxiliary lightning rod 11, causing the lightning field strength to concentrate sharply at the tip, inducing lightning to strike the device; its bottom is directly coupled to the ground via the conductive head 12 and the grounding wire 13, forming a low-impedance discharge path. Simultaneously, the insulation between the assembly cylinder 7 and the support disc 4 ensures that the photovoltaic panel 9 and the auxiliary battery pack 33 are always outside the high-potential shielding area, preventing induced current from flowing back into the DC bus. With the rotatable design of the assembly ring 8, the photovoltaic modules can adjust their tilt angle according to the season, continuously supplying green energy to the auxiliary battery pack 33, achieving parallel operation of the dual circuits where "lightning does not disturb electricity, and electricity does not disturb lightning."

[0022] The three-in-one arrangement of "lightning protection + photovoltaic + energy storage" can be completed on the same roof, without taking up additional roof area, which partially solves the drawbacks of traditional lightning rods that are single-function and wasteful of space.

[0023] In a further preferred embodiment of the present invention, a plurality of blade mounting plates 15 are fixedly installed on the top of the assembly cylinder 7. The plurality of blade mounting plates 15 are evenly distributed in a circular array. Each of the plurality of blade mounting plates 15 is equipped with a fan blade 16, which is used to push the assembly cylinder 7 to rotate along the periphery of the support base 6 when the wind blows. A common waterproof cover 17 is fixedly installed on the outside of the assembly cylinder 7 and the plurality of blade mounting plates 15. A first generator 18 is fixedly installed inside the waterproof cover 17. The first generator 18 is connected to the auxiliary battery pack 33. The top of the support disc 4 is fixedly installed with... An internal gear ring 19 is located outside the supporting cylinder 5 and below the supporting base 6, the assembly cylinder 7, and the assembly ring 8. The same extension shaft 20 is rotatably mounted on the bottom inner wall of the assembly ring 8 and the waterproof cover 17. The top end of the extension shaft 20 is fixedly connected to the shaft of the first generator 18, and the bottom end is fixedly mounted with a driven gear 21. The driven gear 21 meshes with the internal gear ring 19 so that when the assembly cylinder 7 and the assembly ring 8 rotate synchronously, the driven gear 21 rolls along the inner side of the internal gear ring 19, thereby causing the first generator 18 to generate electricity.

[0024] In this embodiment, the mounting base 1 is fixed to the windward side of the roof, so that the wind vane 16 faces the prevailing local wind direction. When the natural wind blows, the wind vane 16 drives the assembly cylinder 7 to rotate freely around the periphery of the support base 6. The assembly cylinder 7 and the waterproof cover 17 are integrated to form a continuous rotation, and the assembly ring 8 rotates synchronously. During the rotation, the driven gear 21 at the top of the extension shaft 20 rolls along the inner side of the fixed internal gear ring 19, converting the low-speed revolution into high-speed rotation, driving the first generator 18 to output AC power. After rectification, the AC power is directly sent to the auxiliary battery pack 33 and stored in parallel with the DC power of the photovoltaic panel 9 to achieve wind-solar complementary charging. The entire device does not require an additional external power source. Wind energy and solar energy are simultaneously fed into the same energy storage unit to complete all-weather green energy harvesting.

[0025] The fan blade 16, assembly cylinder 7, waterproof cover 17, and assembly ring 8 constitute a coaxial rotating assembly. The support base 6 and the internal gear ring 19 remain stationary. When the fan blade 16 is pushed by the airflow, the rotating assembly revolves horizontally around the support base 6, and the extension shaft 20 revolves accordingly. The driven gear 21, due to its meshing with the internal gear ring 19, is forced to rotate. Utilizing the planetary principle of fixed shaft-moving gear, low-speed, high torque is converted into high-speed, low torque, driving the first generator 18 to generate electricity efficiently. The waterproof cover 17 completely seals the first generator 18, the driven gear 21, and the meshing parts, preventing rainwater and salt spray from entering and ensuring long-term reliable gear lubrication and electrical insulation. The insulating support disc 4, support cylinder 5, assembly cylinder 7, and assembly ring 8 further completely isolate the power generation circuit from the lightning current channel, ensuring that lightning strikes do not affect the normal operation of the generator and auxiliary battery pack 33.

[0026] This solution, based on existing photovoltaic, energy storage and lightning protection devices, requires no additional land occupation or new pillars, and achieves wind power generation solely by utilizing the natural wind farm on the roof, significantly increasing the roof's energy density.

[0027] The planetary meshing structure of the internal gear ring-19 and the driven gear-21 directly increases the speed of rotation in large-diameter, low-wind-speed conditions, eliminating the need for the gearbox and yaw system in traditional wind power. It features a compact structure, low noise, and minimal maintenance.

[0028] Wind and solar power are stored together in the auxiliary battery pack 33, forming a complementary power supply. It can continue to charge at night or on rainy days, upgrading the lightning protection device from "passive protection" to "active power generation", further reducing building operating costs.

[0029] In a further preferred embodiment of the present invention, a main shaft 22 is fixedly installed at the bottom end of each of the plurality of fan blades 16, and the plurality of main shafts 22 are rotatably connected to the top wall of the waterproof cover 17. A shaft seat 23 is fixedly installed on each of the plurality of blade mounting plates 15, and a secondary shaft 24 is rotatably installed on each of the plurality of shaft seats 23. The plurality of secondary shafts 24 are respectively fixedly connected to the top of the plurality of fan blades 16. The secondary shafts 24 and the main shafts 22 are coaxially arranged. A bevel gear 25 is fixedly installed at the bottom end of each of the plurality of main shafts 22. A suspension ring 26 located above the auxiliary battery pack 33 is fixedly sleeved on the outside of the assembly cylinder 7. The top of the suspension ring 26 is... An inner cylinder 27 is fixedly installed on the part, and the inner cylinder 27 is located outside the multiple blade mounting plates 15. A linkage ring 28 is rotatably sleeved on the outer side of the inner cylinder 27. The linkage ring 28 meshes with multiple bevel gears 25 so that the windward angle of multiple fan blades 16 is synchronously controlled when the linkage ring 28 rotates. An angle adjustment motor 29 is fixedly installed inside the waterproof cover 17. A drive shaft 30 is fixedly installed on the output shaft of the angle adjustment motor 29. A bevel gear 31 is fixedly sleeved on the drive shaft 30. The bevel gear 31 meshes with one of the bevel gears 25 to provide power for adjusting the windward angle of the fan blades 16.

[0030] In this embodiment, after the roof is installed, the angle adjustment motor 29 drives the drive shaft 30 and the bevel gear 31 to rotate, causing the bevel gear 25 meshing with it to rotate. The main shaft 22 then changes the pitch angle of the corresponding wind blade 16. At the same time, through the meshing relationship between the linkage ring 28 and the inner cylinder 27, all the bevel gears 25 are connected into a synchronous chain, realizing the coordinated pitch adjustment of multiple wind blades 16 at the same angle and in the same direction. After the pitch adjustment is completed, the assembly cylinder 7 rotates as a whole under the action of wind force, and the first generator 18 continues to generate electricity. When the wind speed changes or the wind direction changes abruptly, the remote building automation system can restart the angle adjustment motor 29 again to correct the pitch in real time, maintain the best windward angle and output efficiency, and no manual climbing to the roof is required throughout the process.

[0031] The suspension ring 26 is fixedly connected to the inner cylinder 27 and revolves with the assembly cylinder 7. The linkage ring 28 is floatingly sleeved on the outer gear ring of the inner cylinder 27, revolving with it and rotating relative to the inner cylinder 27. The angle adjustment motor 29 is fixed inside the waterproof cover 17 in the stationary coordinate system. Its output rotation is transmitted to the nearest bevel gear 25 via the second bevel gear 31, causing the blade 16 to change its angle of attack. Since all the bevel gears 25 mesh with the inner side of the linkage ring 28, the angular displacement of a single blade is immediately and synchronously distributed to the other blades through the linkage ring 28, forming a rigid synchronous pitch adjustment mechanism with "one drive for multiple". This structure reduces the number of motors to one, and the motor is located inside the waterproof cover 17, avoiding high potential in the lightning strike area and ensuring that the control circuit and the auxiliary battery pack 33 are at the same safe potential.

[0032] In a further preferred embodiment of the present invention, a plurality of wind speed sensors 32 are installed on the plurality of blade mounting plates 15. The plurality of wind speed sensors 32 are connected to the angle adjustment motor 29 and the auxiliary battery pack 33 by a controller, and are used to adjust the windward angle of the wind blade 16 according to the wind speed. The plurality of wind speed sensors 32 are respectively arranged in multiple directions.

[0033] In this embodiment, during the rotation of the assembly ring 8, wind speed sensors 32 distributed on each blade mounting plate 15 perform multi-directional real-time sampling of the incoming wind speed. After the sampling signal is sent to the controller, it is compared with the preset start-up, rated, and cut-off wind speed ranges. Subsequently, a PWM command is output to the angle adjustment motor 29, driving the second bevel gear 31, the first bevel gear 25, and the linkage ring 28 to complete synchronous pitch control. When the wind speed is lower than the start-up value, the controller increases the pitch angle to reduce the start-up torque. After the wind speed enters the working range, it gradually returns to the optimal angle of attack. If the wind speed exceeds the safety limit, the controller immediately commands all blades 16 to feather, and simultaneously cuts off the excitation of the first generator 18 to achieve self-protection. The entire closed-loop control is independently powered by the auxiliary battery pack 33, without the need for external mains power, ensuring reliable adjustment even at night or when mains power is interrupted.

[0034] Multi-directionally arranged wind speed sensors 32 revolve with the rotating component, obtaining instantaneous wind speed samples with different phase angles within the same circumferential plane. The controller uses a vector synthesis algorithm to eliminate tower shadow effects and turbulence spikes, obtaining the true incoming flow velocity. Subsequently, using this velocity as a single input variable, the corresponding pitch angle setpoint is output from a lookup table, and the motor current and the angular displacement of the linkage loop 28 are fed back in real time in a closed loop, forming a three-loop control of "wind speed-pitch-power". Since the controller and angle adjustment motor 29 are both at a floating ground potential, they are completely isolated from the high-potential discharge channels of the lightning arrester 10 and the grounding wire 13. Even if a violent electromagnetic pulse is generated at the moment of a lightning strike, the control signal is transmitted through shielded twisted-pair cable and optical fiber, ensuring that the pitch adjustment command is not lost or malfunctions.

[0035] In a further preferred embodiment of the present invention, the claw frame 3 is made of insulating material, and a wire hole is provided on the claw frame 3, through which the grounding wire 13 passes.

[0036] In this embodiment, during installation, the grounding wire 13 is first laid along the inner side of the support column 2, passes through the pre-drilled hole on the insulating claw bracket 3, and then extends downwards to the grounding base 14. The inner diameter of the hole is larger than the outer diameter of the wire, and the corners are rounded to prevent sharp edges from cutting the insulation layer. Since the claw bracket 3 is made of insulating material, the wire remains isolated from the metal components when passing through the mechanical support node, and can be laid in one go without additional sleeves, simplifying the construction steps and reducing roof operation time.

[0037] In a further preferred embodiment of the present invention, a plurality of blade mounting plates 15 are distributed around a plurality of auxiliary pins 11, the plurality of blade mounting plates 15 are all made of insulating material, and the top height of the plurality of blade mounting plates 15 is lower than the height of the auxiliary pins 11.

[0038] In this embodiment, at the moment of lightning strike, the main lightning rod 10 and the auxiliary lightning rod 11 form the highest potential area. Since the top of the blade mounting plate 15 is lower than the auxiliary lightning rod 11 and the material is insulated, the downward leader preferentially chooses the tip of the auxiliary lightning rod 11 to develop, and will not jump to the wind blade 16 or the wind speed sensor 32.

[0039] In a further preferred embodiment of the present invention, multiple photovoltaic power generation panels 9 are provided, all located around the waterproof cover 17. The waterproof cover 17 is made of insulating material, and the installation height of the photovoltaic power generation panels 9 is lower than the top height of the waterproof cover 17.

[0040] In this embodiment, multiple photovoltaic panels 9 are evenly laid along the circumference on the top surface of the mounting ring 8 surrounding the waterproof cover 17, with their highest point lower than the top edge of the waterproof cover 17. During normal operation, the mounting ring 8 rotates with the wind, and the photovoltaic array rotates synchronously, continuously tracking the ambient scattered light. During thunderstorms, the waterproof cover 17 uses its insulating top cover to shield the upper lightning protection area, and the photovoltaic panels 9 are protected by the shade of the cover. Long-term outdoor operation can be achieved without additional lightning rods or shielding nets on site.

[0041] In a further preferred embodiment of the present invention, a meshing groove is provided on the periphery of the linkage ring 28, and the plurality of bevel gears 25 are all engaged in rolling meshing with the meshing groove.

[0042] In this embodiment, the meshing groove on the outer periphery of the linkage ring 28 is a continuous annular toothed track, and the tooth tips of each bevel gear 25 maintain line contact with the groove wall for rolling. When any gear is driven by the angle adjustment motor 29, its rotational motion is converted into pure rolling of the linkage ring 28 around the inner cylinder 27, which in turn pushes the remaining bevel gears 25 through the groove wall, so that all the fan blades 16 synchronously obtain the same angular displacement. The closed structure of the meshing groove restricts the axial movement of the gears, ensuring no backlash slippage during pitch adjustment.

[0043] In a further preferred embodiment of the present invention, the auxiliary battery pack 33 includes a battery pack, a rectifier, a control module and a power supply module, and the drive shaft 30 is located around the suspension ring 26, the inner cylinder 27 and the linkage ring 28.

[0044] In this embodiment, the rectifier in the auxiliary battery pack 33 converts the alternating current from the photovoltaic and the first generator 18 into direct current, which is then stored in the battery pack. The control module reads the data from the wind speed sensor 32 in real time. When the wind speed change exceeds the set range, it immediately triggers the power supply module to provide a pulse current to the angle adjustment motor 29. The motor drives the linkage ring 28 to rotate through the drive shaft 30, bevel gear 21, and bevel gear 25 located on the periphery, thereby completing the angle adjustment of the wind blade 16. The drive shaft 30 is suspended outside the suspension ring 26, inner cylinder 27, and linkage ring 28, and does not intersect with the lightning current channel. Furthermore, the control module and the power supply module are placed inside the insulated auxiliary battery pack 33, forming potential isolation to ensure that the high-voltage pulse will not enter the low-voltage control circuit in the reverse direction along the drive shaft 30 during a lightning strike.

[0045] In a further preferred embodiment of the present invention, the bottom of the support base 6 is provided with an embedding opening, and the conductive head 12 and the grounding wire 13 are embedded into the support base 6 through the embedding opening and fastened with bolts.

[0046] In this embodiment, an insertion port is pre-fabricated at the bottom of the support base 6. The conductive head 12 and the crimped terminal of the grounding wire 13 are inserted into the insertion port together, so that the top surface of the conductive head 12 fits tightly against the conductive platform inside the cavity of the support base 6. Then, the bolt is screwed in from the side and the rated torque is applied to complete the one-time tightening. During on-site installation, it is only necessary to put the support base 6 into the top of the support cylinder 5, and then lead the grounding wire 13 along the inner side of the support column 2 to the grounding base 14. If maintenance is required, the conductive head 12 and the grounding wire 13 can be pulled out as a whole by loosening the bolts, without disassembling the lightning protection main pin 10 or auxiliary pin 11 above the support base 6, so as to achieve quick maintenance.

[0047] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a connecting frame 34 is fixedly installed on each of the plurality of blade mounting plates 15, and the same connecting ring 35 is fixedly installed on the plurality of connecting frames 34. The same reinforcing inner ring 44 is fixedly installed on the inner side of the plurality of blade mounting plates 15 by bolts. The connecting ring 35 and the reinforcing inner ring 44 are located on the periphery of the plurality of auxiliary pins 11, and the connecting frame 34, the connecting ring 35 and the reinforcing inner ring 44 are all made of insulating material.

[0048] In this embodiment, the connecting ring 35 connects multiple blade mounting plates 15 through the connecting frame 34, and the reinforcing inner ring 44 is at the root. The two form a double-ring constraint structure, which transforms the discrete cantilever plate into an integral cylindrical frame, significantly reducing radial deformation and torsional displacement under wind load.

[0049] In another embodiment of the present invention, a lower mesh cover 36 is fixedly installed on the top of the waterproof cover 17, and a mesh cover 37 is detachably installed on the top of the lower mesh cover 36 by bolts. An insulating cylinder 38 is fixedly embedded on the mesh cover 37, and the insulating cylinder 38 is slidably sleeved on the lightning arrester main needle 10. The mesh cover 37 and the lower mesh cover 36 are both located outside the blade mounting plate 15, the wind blade 16, the auxiliary needle 11 and the wind speed sensor 32 for protection. The lower mesh cover 36, the mesh cover 37 and the insulating cylinder 38 are all made of insulating material.

[0050] In this embodiment, the lower mesh cover 36 and the upper mesh cover 37 form a double-layer annular shield. The mesh not only blocks foreign objects such as birds and ribbons but also maintains ventilation and reduces drag. The insulating cylinder 38 slides on the outer wall of the lightning arrester main rod 10, providing a central positioning for the lower mesh cover 36 and the upper mesh cover 37, ensuring that the cover does not collide with the lightning arrester main rod 10 under strong winds or rotational vibrations. The lower mesh cover 36, the upper mesh cover 37, and the insulating cylinder 38 are all made of insulating material, completely isolating the internal mechanical and electronic components from the high-voltage lightning protection area. Even if the potential of the lightning arrester main rod 10 rises sharply at the moment of lightning strike, the surfaces of the lower mesh cover 36 and the upper mesh cover 37 remain at a floating ground potential, preventing induced current from entering the control circuit of the wind speed sensor 32 or the angle adjustment motor 29.

[0051] In another embodiment of the present invention, an external gear ring 39 is fixedly installed on the outer ring of the assembly ring 8, a protective shell 40 is fixedly installed on the support disk 4, a second generator 41 is fixedly installed inside the protective shell 40, the output shaft of the second generator 41 is rotatably installed on the support disk 4, a driven gear 42 is fixedly installed on the output shaft of the second generator 41, the driven gear 42 meshes with the external gear ring 39 so that the second generator 41 is driven to generate electricity when the assembly cylinder 7 and the assembly ring 8 rotate synchronously, and a main battery pack 43 is fixedly installed at the bottom of the support disk 4, the main battery pack 43 is connected to the second generator 41 for energy storage.

[0052] In this embodiment, a protective shell 40 is pre-installed on the support disk 4, and the second generator 41 is fixed inside the protective shell 40, with the driven gear 42 meshing with the external gear ring 39. When the fan blade 16 drives the assembly cylinder 7 and the assembly ring 8 to rotate, the external gear ring 39 rotates synchronously, driving the driven gear 42 and the second generator 41 to output AC power, which is rectified and stored in the main battery pack 43, completing the secondary recovery of wind energy. The main battery pack 43 is located at the bottom of the support disk 4 and is powered separately from the auxiliary battery pack 33, and can independently provide power for the building's DC bus or emergency lighting.

[0053] In another embodiment of the present invention, the top of the assembly ring 8 is provided with a plurality of sliding grooves 45, and a guide rod 46 is fixedly installed in each of the plurality of sliding grooves 45. A slider 47 and a return spring 48 are slidably sleeved on each of the plurality of guide rods 46. The two ends of the return spring 48 respectively abut against the slider 47 and the inner wall of the sliding groove 45. The plurality of sliders 47 slide along the plurality of sliding grooves 45. A drive rack 49 is fixedly installed on the top of each of the plurality of sliders 47. The plurality of drive racks 49 are slidable along the top of the assembly ring 8. Each of the driving racks 49 has side lugs 50 fixedly mounted on the top of the assembly ring 8 on both sides. A common rotating shaft 51 is rotatably mounted on each of the two corresponding side lugs 50. Multiple residual tooth seats 52 are fixedly sleeved on each of the rotating shafts 51. These residual tooth seats 52 mesh with the driving racks 49 respectively, so that the residual tooth seats 52 rotate when the driving racks 49 slide. Extension plates 53 are fixedly mounted on each of the residual tooth seats 52, and photovoltaic mounting plates 54 are fixedly mounted on the top of each of the extension plates 53. The photovoltaic mounting plate 54 is installed on multiple photovoltaic panels 9 respectively, so that the tilt angle of the photovoltaic panels 9 can be adjusted according to the wind speed. A track ring 55 is fixedly installed on the inner wall of the waterproof cover 17. The track ring 55 is located on the outer periphery of the inner cylinder 27. A tensioning toothed ring 56 is rotatably sleeved inside the track ring 55. Multiple pull ropes 57 are fixedly installed at the bottom of the tensioning toothed ring 56. The pull ropes 57 slide through the bottom inner wall of the waterproof cover 17. The bottom ends of the pull ropes 57 are fixedly connected to multiple drive racks 49 respectively. The tensioning ring 56 is rotated to loosen or loosen the tensioning rope 57, which in turn works with the return spring 48 to control the position of the slider 47 and the drive rack 49, thereby controlling the pitch angle of the photovoltaic panel 9. A drive gear 58 is fixedly sleeved on the drive shaft 30. The drive gear 58 meshes with the inner side of the tensioning ring 56, so that the angle adjustment motor 29 can simultaneously adjust the angle of the wind blade 16 and the photovoltaic panel 9 according to the wind speed. Multiple guide rope blocks 59 are fixedly installed on the top of the assembly ring 8, and multiple pull ropes 57 slide through multiple guide rope blocks 59 respectively.

[0054] In this embodiment, the angle adjustment motor 29 is fixed inside the waterproof cover 17, and a drive gear 58 is coaxially mounted on its output shaft. When the angle adjustment motor 29 is rotated under control, the drive gear 58 transmits torque to the tensioning gear ring 56 meshing with it. The tensioning gear ring 56 is confined within the annular cavity of the track ring 55 and can only roll around the axis of the inner cylinder 27, thereby converting the local small-angle rotation of the angle adjustment motor 29 into the continuous circular motion of the entire tensioning gear ring 56, realizing the synchronous winding and unwinding of multiple pull ropes 57.

[0055] Each pull rope 57 is fixed at its upper end to the bottom of the tensioning ring 56, passes sequentially through the bottom opening of the waterproof cover 17 and the limiting channel of the guide rope block 59, and is fixed at its lower end to the tail end of the corresponding drive rack 49. When the tensioning ring 56 rotates forward, the pull rope 57 is pulled upward, generating a horizontal pulling force on the drive rack 49, overcoming the preload of the return spring 48, and pulling the slider 47 to slide inward along the guide rod 46; when the angle adjustment motor 29 rotates in reverse, the return spring 48 releases energy, pushing the slider 47 to return outward, and the pull rope 57 relaxes accordingly, keeping the rope system in a closed-loop balance state of tension and relaxation.

[0056] The drive rack 49 maintains backlash-free meshing with the sector-shaped tooth segment on the residual tooth holder 52. The linear displacement of the drive rack 49 is converted into the angular displacement of the residual tooth holder 52. The residual tooth holder 52 rotates on a fixed axis via the rotating shaft 51, supported by the lugs 50 on both sides. The extension plate 53 and the photovoltaic mounting plate 54 fixed on the residual tooth holder 52 tilt synchronously, thereby changing the tilt angle of the photovoltaic panel 9. Since all drive racks 49 share the same tensioning ring 56, each residual tooth holder 52 obtains a strictly consistent rotation angle, ensuring synchronous tilting of multiple photovoltaic panels 9.

[0057] The wind speed sensor 32 outputs a real-time signal to the control module inside the auxiliary battery pack 33: when the wind speed exceeds the set threshold, the control module causes the angle adjustment motor 29 to rotate in the forward direction, the drive gear 58 drives the tensioning ring 56 to tighten the pull rope 57, the pitch angle of the photovoltaic panel 9 decreases, and the windward area decreases; after the wind speed drops, the angle adjustment motor 29 rotates in the reverse direction, the reset spring 48 automatically pushes the slider 47 outward, and the photovoltaic panel 9 restores the optimal light tilt angle, realizing the adaptive protection of "lying flat when the wind is strong and standing upright when the wind is weak".

[0058] In another embodiment of the present invention, a stabilizing ring 60 is fixedly installed at the bottom of the assembly ring 8. The stabilizing ring 60 is located outside the inner toothed ring 19. A plurality of balls 61 are movably embedded at the bottom of the stabilizing ring 60, and the plurality of balls 61 can roll along the top of the supporting disc 4.

[0059] In this embodiment, a stabilizing ring 60 is integrally locked onto the bottom surface of the assembly ring 8, and the ball bearings contact the top surface of the supporting disk 4 to form a pre-tightened rolling pair. The entire weight of the assembly cylinder 7, the assembly ring 8, the upper wind blades, and the photovoltaic modules is transferred to the ball bearings 61 through the stabilizing ring 60, and then evenly distributed to the supporting disk 4, maintaining a horizontal position without additional adjustment.

[0060] In summary, compared with related technologies, this device completes the three-in-one arrangement of "lightning protection + photovoltaic + energy storage" without occupying additional roof area, and partially solves the drawbacks of traditional lightning rods, such as single function and wasted space.

[0061] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
