Description

Technical Field

[0001] This application relates to the field of building lightning protection technology, and in particular to a lightning protection device for the protection of ancient buildings. Background Technology

[0002] Ancient building preservation is a complex and important task. Its core objective is to carefully maintain, scientifically restore, and effectively pass on ancient buildings that carry multiple values ​​of history, science, and art. However, the main frame of most ancient buildings is made of wood, which is very susceptible to damage from lightning strikes during thunderstorms. Therefore, equipping ancient buildings in scenic areas with necessary lightning protection measures has become a key aspect of ancient building preservation.

[0003] To address the aforementioned needs, relevant technological fields have yielded corresponding research and development achievements in lightning protection devices. For example, Chinese patent with announcement number "CN218733151U" discloses a lightning protection device for the protection of ancient buildings. This device relates to the field of ancient building protection technology and mainly includes a base and a lightning rod. The lightning rod is fixedly installed on the upper side of the base, and a stabilizing ring is set around the lightning rod. Support frames are rotatably connected to both sides of the stabilizing ring. The core design advantage of this lightning protection device is that it can be installed without damaging the building surface. Specifically, the initial stabilization of the lightning protection device is achieved through two clamping blocks on the lower side. Then, the fixing seat on the lower side of the stabilizing plate is fixed. The ground-adhesive seat structure on the lower side of the fixing seat is used to adhere to the installation surface, and the clamping blocks on both sides are used to achieve a stable fixation of the base. At the same time, the support frames on both sides cooperate with the scissor frame structure that unfolds on the lower side to give the upper lightning rod a certain anti-collapse capability. It has the characteristics of simple installation structure and high installation efficiency.

[0004] Although the existing lightning protection devices have certain advantages in terms of ease of installation and building protection, they still have significant defects and shortcomings in practical applications. Specifically, the design improvements of existing devices focus on optimizing the installation method, without specifically optimizing the core lightning protection performance. Since lightning rods are exposed to the outdoor environment for a long time, dust easily accumulates on their surface. They are also easily covered by debris such as leaves, dead leaves, and household garbage blown by the wind. Over time, a layer of dirt will form on the surface of the lightning rod. This dirt layer will cover the surface of the lightning rod, which will seriously affect the conductivity of the lightning rod and ultimately lead to a significant decrease in lightning protection effectiveness. This will not be able to fully guarantee the lightning protection safety of ancient buildings. Based on this, there is still room for improvement in the existing lightning protection devices for ancient buildings, and it is urgent to solve the above-mentioned problems of insufficient lightning protection performance through targeted design improvements. Summary of the Invention

[0005] In order to ensure the protective effect of existing lightning protection devices, this application provides a lightning protection device for the protection of ancient buildings.

[0006] This application provides a lightning protection device for the protection of ancient buildings, which adopts the following technical solution: it includes an installation ring frame, on the top of which a support frame is fixedly installed in a ring at equal intervals, a top ring is fixedly installed on the top of the support frame, a lightning rod base is movably installed on the inner side of the top ring, a lightning rod body is rotatably connected to the top of the lightning rod base, a cleaning mechanism is movably installed on the outer side of the top ring, a motor drive mechanism is fixedly installed on one side of the bottom of the top ring, the motor drive mechanism is used to drive the lightning rod base to rise and fall, a wind-driven mechanism is fixedly installed on the upper side of one side of the lightning rod base, and a grounding wire is fixedly connected to the bottom of the lightning rod base;

[0007] The motor drive mechanism includes a fixed arm and a first rack. The fixed arm is fixedly installed on one side of the bottom of the top ring, and the first rack is fixedly installed on one side of the bottom of the lightning rod base.

A first gear is fixedly installed at the output end of the drive motor, and the first gear and the first rack are meshed together. A protective shield is provided on the outside of the drive motor. The protective shield specifically consists of a lightning protection layer, an electromagnetic shielding layer, and an insulating layer. When the drive motor runs, it drives the first gear to drive the first rack to rise and fall, which in turn drives the lightning rod base to rise and fall. The rise and fall of the lightning rod base can then drive the external cleaning mechanism in conjunction. By lowering the lightning rod base, the lightning rod can be moved to a higher position. The cleaning mechanism rotates upwards and closes to fit the outer surface of the lightning rod body. At this time, the wind-driven mechanism drives the lightning rod body to rotate, while the cleaning mechanism is stationary. The cleaning mechanism can then brush and clean the outer surface of the lightning rod body. After cleaning, the drive motor reverses direction to move the lightning rod base upwards. At this time, the cleaning mechanism unfolds and rotates downwards outwards. Simultaneously, the upward movement of the lightning rod base causes the lightning rod body to detach from the inner side of each cleaning mechanism and move upwards to avoid the impact of lightning strikes on the cleaning mechanism. At the same time, its fixed base frame, top ring, support frame, and other structures can be made of insulating materials, allowing lightning to be conducted into the ground through the lightning rod body.

[0010] Optionally, the transmission assembly further includes an outer hinge seat and a second rack. The outer hinge seats are arranged in a ring at equal intervals and fixedly installed on the outside of the top ring. The second rack is fixedly installed on the outside of the lifting slide plate.

A second gear is fixedly installed in the middle of the rotating shaft. The second gear and the second rack are meshed together. The cleaning assembly is hinged to the outside of the outer hinge seat via the rotating shaft.

[0011] Optionally, the cleaning assembly includes a mounting frame, which is fixedly mounted on the outer end of the rotating shaft. The mounting frame is hinged to the outer side of the outer hinge seat via the rotating shaft. A mounting sleeve is fixedly mounted on the outer side of the mounting frame. A bent mounting rod is inserted into the inner side of the mounting sleeve. A cleaning brush plate is fixedly mounted on the outer end of the bent mounting rod. After the lightning rod base moves downward, the cleaning brush plate rotates and fits against the outer surface of the lightning rod body to clean its surface.

[0012] Optionally, the outer side of the mounting sleeve is threaded with a mounting screw, the end of which passes through the mounting sleeve and is threadedly connected to the bent mounting rod. The mounting screw is a hand-tightening screw, and the top view shape of the slide groove and the lifting slide plate is both set to a convex shape.

[0013] Optionally, the wind-driven mechanism and the lightning rod body are connected by a transmission, and the outer side of the mounting ring frame is provided with mounting circular plates arranged in a ring at equal intervals. Each mounting circular plate has a mounting hole in the middle, and the mounting hole is set as a countersunk hole. The grounding wire and the lightning rod body are electrically connected.

[0014] Optionally, the wind-driven mechanism includes a transmission module and a wind-driven assembly. Both the wind-driven assembly and the transmission module are fixedly installed on the upper side of one side of the lightning rod base. The transmission module is located above the wind-driven assembly, and the wind-driven assembly is connected to the lightning rod body via the transmission module.

[0015] Optionally, the transmission module includes a bending connecting rod and a gear ring. The bending connecting rod is fixedly installed on the upper side of one side of the lightning rod base. A third gear is rotatably connected to the top of the bending connecting rod. The gear ring is fixedly installed at the bottom edge of the lightning rod body. The third gear and the gear ring are meshed together. A first synchronous pulley is fixedly connected to the top of the third gear.

[0016] Optionally, the wind-driven assembly includes a bending arm, which is fixedly installed on the upper side of one side of the lightning rod base. The bending arm is located below the bending link, and a circular seat is fixedly installed on the outer end of the bending arm. A second synchronous pulley is rotatably connected to the top of the circular seat. The second synchronous pulley is connected to the first synchronous pulley via a synchronous belt. A vertical axis wind turbine rotor is fixedly installed on the top of the second synchronous pulley.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] During the application of this technical solution, the coordinated operation of the cleaning mechanism and the wind-driven motor drive mechanism allows for regular brushing and cleaning of the outer surface of the lightning rod. Combined with rainwater rinsing during rainy days, this further enhances the cleaning effect, effectively removing surface debris and preventing the formation of a dirt layer. This ensures the stable conductivity of the lightning rod and solves the problem of decreased lightning protection performance due to surface dirt accumulation when lightning rods are exposed outdoors for extended periods. Furthermore, the wind-driven cleaning power requires no additional electricity input, making it suitable for outdoor ancient building areas. This reduces energy consumption, ensures stable operation, and eliminates the need for frequent maintenance. The coordinated transmission components ensure precise power transmission, making the rotation angle of the cleaning mechanism and the rotation speed of the lightning rod controllable, further improving the cleaning effect.

[0019] During the application of this technical solution, a motor-driven mechanism is used to raise and lower the lightning rod base, enabling orderly switching between cleaning and lightning protection during use. During cleaning, the cleaning mechanism adheres to the lightning rod body and unfolds after cleaning, thus avoiding damage to the cleaning mechanism from lightning strikes and ensuring that the lightning rod is in the optimal lightning protection position. This solves the problem in existing technologies where lightning protection and cleaning functions cannot be coordinated and are prone to mutual interference. At the same time, a protective shielding cover ensures the stable operation of the motor-driven mechanism and ensures the linkage accuracy of the cleaning mechanism. The convenient disassembly and assembly structure of the cleaning components facilitates the maintenance of the cleaning brush plate. The installation structure ensures stable installation and avoids damage to the appearance and structure of ancient buildings, ensuring the long-term stable operation of the device.

Detailed Implementation

[0029] The following combination Figures 1-8 This application will be described in further detail.

[0030] This application discloses a lightning protection device for the protection of ancient buildings. For example... Figures 1-8 As shown, the system includes a mounting ring frame 1, a support frame 2 fixedly mounted on the top of the mounting ring frame 1 in a ring shape with equal spacing, a top ring 3 fixedly mounted on the top of the support frame 2, a lightning rod base 4 movably mounted on the inner side of the top ring 3, a lightning rod body 5 rotatably connected to the top of the lightning rod base 4, a cleaning mechanism 6 movably mounted on the outer side of the top ring 3, a motor drive mechanism 7 fixedly mounted on one side of the bottom of the top ring 3, the motor drive mechanism 7 being used to drive the lightning rod base 4 to rise and fall, a wind-driven mechanism 9 fixedly mounted on the upper side of one side of the lightning rod base 4, and a grounding wire 8 fixedly connected to the bottom of the lightning rod base 4.

[0031] The motor drive mechanism 7 includes a fixed arm 71 and a first rack 72. The fixed arm 71 is fixedly installed on one side of the bottom of the top ring 3, and the first rack 72 is fixedly installed on one side of the bottom of the lightning rod base 4. A fixed base frame 73 is fixedly installed at the bottom end of the fixed arm 71, and a drive motor 74 is fixedly installed on one side of the fixed base frame 73. A first gear 75 is fixedly installed at the output end of the drive motor 74, and the first gear 75 and the first rack 72 are meshed together. During the application of this device, through the coordinated operation of the mounting ring frame 1, support frame 2, top ring 3, lightning rod base 4, lightning rod body 5, cleaning mechanism 6, motor drive mechanism 7, and grounding wire 8, a stable installation support foundation can be constructed based on the mounting ring frame 1 and support frame 2. The top ring 3 provides an installation and movement carrier for the lightning rod base 4 and the cleaning mechanism 6. When it is necessary to adjust the position of the lightning rod base 4, the motor drive mechanism 7 is activated, and the motor drives... The drive motor 74 in mechanism 7 drives the first gear 75 at the output end to rotate. Since the first gear 75 meshes with the first rack 72 fixed on one side of the lightning rod base 4, the rotation of the first gear 75 can be converted into the linear motion of the first rack 72, thereby driving the lightning rod base 4 to achieve lifting and lowering adjustment along the inner side of the top ring 3. The lifting and lowering of the lightning rod base 4 can be linked to the operation of the cleaning mechanism 6. At the same time, the lightning rod body 5 can be adjusted in position through the lightning rod base 4 to better perform its lightning protection function. The grounding wire 8 can conduct the lightning current received by the lightning rod body 5. This structural design can accurately control the lifting and lowering of the lightning rod base 4 through the motor drive mechanism 7, ensuring that the relative position adjustment between the cleaning mechanism 6 and the lightning rod body 5 is accurate and reliable. At the same time, the stable support of the mounting ring frame 1 and the support frame 2 ensures the structural stability of the entire device during operation, avoiding the impact of unstable support on the realization of lightning protection and cleaning functions.

[0032] Please refer to Figures 1-5 and Figure 7The wind-driven mechanism 9 and the lightning rod body 5 are connected by a transmission. The outer side of the mounting ring frame 1 is provided with equally spaced, ring-shaped mounting plates 10. Each mounting plate 10 has a mounting hole 11 in its center, which is a countersunk hole. The grounding wire 8 and the lightning rod body 5 are electrically connected. The wind-driven mechanism 9 includes a transmission module 91 and a wind-driven assembly 92. Both the wind-driven assembly 92 and the transmission module 91 are fixedly installed on the upper side of the lightning rod base 4. The transmission module 91 is positioned above the wind-driven assembly 92. The wind-driven assembly 92 is connected to the lightning rod body 5 via the transmission module 91. The transmission module 91 includes a bent connecting rod 911 and a toothed ring 912. The bent connecting rod 911 is fixedly installed on the upper side of the lightning rod base 4. A third gear 913 is rotatably connected to the top of the bending connecting rod 911. A gear ring 912 is fixedly installed at the bottom edge of the lightning rod body 5. The third gear 913 and the gear ring 912 are meshed together. A first synchronous pulley 914 is fixedly connected to the top of the third gear 913. The wind-driven assembly 92 includes a bending connecting arm 921, which is fixedly installed on the upper side of one side of the lightning rod base 4. The bending connecting arm 921 is located below the bending connecting rod 911. A round seat 922 is fixedly installed at the outer end of the bending connecting arm 921. A second synchronous pulley 923 is rotatably connected to the top of the round seat 922. The second synchronous pulley 923 is connected to the first synchronous pulley 914 via a synchronous belt. A vertical axis wind turbine rotor 924 is fixedly installed on the top of the second synchronous pulley 923. During application, this device, through the coordinated operation of the transmission module 91 of the wind-driven mechanism 9, the wind-driven component 92, and the mounting circular plate 10, countersunk hole, and grounding wire 8, enables the vertical axis wind turbine rotor 924 to rotate using natural wind power. The rotor rotation drives the second synchronous pulley 923 to rotate accordingly. The second synchronous pulley 923 transmits power to the first synchronous pulley 914 via a synchronous belt. The first synchronous pulley 914 then drives the fixed third gear 913 to rotate. Since the third gear 913 meshes with the gear ring 912, the rotation of the third gear 913 drives the gear ring 912 and the lightning rod body 5 connected to the gear ring 912 to rotate, realizing the conversion of wind power into the rotational power of the lightning rod body 5. At the same time, the mounting circular plate 10... The countersunk holes on the lightning rod allow for the stable installation of fasteners, preventing them from being exposed and affecting the aesthetics of the installation. The grounding wire 8 smoothly discharges the lightning current received by the lightning rod body 5, ensuring the normal operation of the lightning protection function. The bent connecting rod 911 in the transmission module 91 provides stable support for the third gear 913, ensuring the accuracy of gear meshing transmission. The bent connecting arm 921 in the wind-driven component 92 provides a stable load-bearing function for the round seat 922 and the second synchronous pulley 923. The synchronous belt drive, combined with the gear meshing transmission, enables efficient power transmission, allowing the rotational movement of the lightning rod body 5 to be smooth and controllable. Relying on natural wind power as a power source, no additional power input is required, making it suitable for outdoor ancient building applications and reducing the operating energy consumption of the device.The countersunk hole design allows the device to be installed in a way that better suits the aesthetic requirements of preserving ancient buildings, while the electrical connection between the grounding wire 8 and the lightning rod body 5 directly ensures the core requirement of lightning protection safety.

[0033] Please refer to Figures 1-4 and Figure 8 The cleaning component 64 includes a mounting frame 641, which is fixedly mounted on the outer end of a rotating shaft 635. The mounting frame 641 is hinged to the outer side of an outer hinge seat 633 via the rotating shaft 635. A mounting sleeve 642 is fixedly mounted on the outer side of the mounting frame 641. A bent mounting rod 643 is inserted into the inner side of the mounting sleeve 642. A cleaning brush plate 644 is fixedly mounted on the outer end of the bent mounting rod 643. A mounting screw 645 is threadedly connected to the outer side of the mounting sleeve 642. The end of the device is threaded through the mounting sleeve 642 and the bent mounting rod 643. The mounting screw 645 is a hand-tightening screw. The slide groove 631 and the lifting slide plate 632 are both convex in shape when viewed from above. During the application of this device, through the coordinated cooperation of the mounting frame 641, mounting sleeve 642, bent mounting rod 643, cleaning brush plate 644 and hand-tightening mounting screw 645 of the cleaning component 64, the mounting frame 641 can be driven by the rotation of the rotating shaft 635. The synchronous movement of the mounting bracket 641 causes the mounting sleeve 642 and the bent mounting rod 643 inserted in the mounting sleeve 642 to move together, thereby adjusting the position of the cleaning brush plate 644 at the outer end of the bent mounting rod 643 to meet the fitting requirements of the lightning rod body 5 during cleaning operations. When installing or maintaining the cleaning brush plate 644, the bent mounting rod 643 and the mounting sleeve 642 can be fixed or disassembled directly by hand-tightening the mounting screw 645 without the need for additional tools, making the operation convenient and efficient. At the same time, the convex structure design of the slide groove 631 and the lifting slide plate 632 can ensure the guiding accuracy of the lifting slide plate 632 during the sliding process, avoiding deviation or detachment during sliding, ensuring that the movement of the entire cleaning assembly 64 remains stable and smooth, further improving the reliability of the cleaning operation. The setting of the hand-tightening mounting screw 645 greatly simplifies the replacement and maintenance process of the cleaning brush plate 644, ensuring that the device can play a stable cleaning role for a long time.

[0034] Please refer to Figures 1-5 and Figure 8The cleaning mechanism 6 includes an outer ring 61, which is fitted onto the outer surface of the lightning rod base 4. Connecting blocks 62 are fixedly installed in a ring at equal intervals on the inner side of the outer ring 61. The connecting blocks 62 are screwed onto the outer surface of the lightning rod base 4. A transmission assembly 63 is located at the bottom of the outer ring 61, and is movably positioned in a ring at equal intervals on the outer side of the top ring 3. A cleaning assembly 64 is located on the outer side of the transmission assembly 63. The transmission assembly 63 includes a sliding groove 631, which is slidably positioned in a ring at equal intervals on the outer side of the top ring 3. A lifting slide plate 632 is slidably connected inside the sliding groove 631. The top of the lifting slide plate 632 is fixedly connected to the top of the outer ring 61. The lightning rod base 4 is connected via the sliding groove... The lifting slide plate 631 and 632 are slidably mounted on the inner side of the top ring 3. The transmission assembly 63 also includes an outer hinge seat 633 and a second rack 634. The outer hinge seats 633 are evenly spaced and arranged in a ring shape and fixedly installed on the outer side of the top ring 3. The second rack 634 is fixedly installed on the outer side of the lifting slide plate 632. A rotating shaft 635 is rotatably connected to the inner side of the outer hinge seat 633. Both ends of the rotating shaft 635 pass through the outer hinge seat 633. A second gear 636 is fixedly installed in the middle of the rotating shaft 635. The second gear 636 and the second rack 634 are meshed and connected. The cleaning assembly 64 is hinged to the outer side of the outer hinge seat 633 via the rotating shaft 635. During the application of this device, it is connected to the outer ring 61 of the cleaning mechanism 6. The coordinated operation of block 62, transmission component 63, and cleaning component 64 allows the outer ring 61 to move stably and synchronously with the lightning rod base 4 during use, thanks to the cooperation of the connecting block 62 and the screw. When the lightning rod base 4 rises or falls, it drives the outer ring 61 to move together. The outer ring 61, through its fixed connection with the lifting slide plate 632, drives the lifting slide plate 632 to slide along the inside of the slide groove 631. During the sliding process of the lifting slide plate 632, it drives the outer second rack 634 to move synchronously. Since the second rack 634 meshes with the second gear 636 in the middle of the rotating shaft 635, the movement of the second rack 634 is converted into the rotation of the second gear 636, which in turn drives the rotating shaft 635 to rotate inside the outer hinge seat 633. The rotation of the pivot 635 will drive the cleaning component 64, which is hinged to the outside of the outer hinge seat 633, to move synchronously, realizing the opening and closing adjustment of the cleaning component 64. This structural design allows the cleaning mechanism 6 and the lightning rod base 4 to achieve precise linkage in lifting and lowering. The cooperation between the slide groove 631 and the lifting slide plate 632 ensures the stability and smoothness of the sliding process and avoids jamming. At the same time, the meshing transmission of gears and racks ensures the precision and efficiency of power transmission, making the opening and closing angle of the cleaning component 64 controllable and able to accurately meet the needs of subsequent cleaning operations. The stable connection between the outer ring 61 and the lightning rod base 4 through the connecting block 62 ensures the synchronicity of the linkage movement and ensures the stable and reliable operation of the entire cleaning mechanism 6.

[0035] The implementation principle of the lightning protection device for the protection of ancient buildings in this application embodiment is as follows: The first step in the use of this technical solution is the installation and fixing stage. The installation ring frame 1 serves as the bearing foundation of the entire device. The installation circular plate 10 on the outer side is used to fix it to the designated installation position of the ancient building. The countersunk hole in the middle of the installation circular plate 10 can be used to fit fasteners such as bolts. When the fastener passes through the countersunk hole and connects with the installation surface of the ancient building, the fixing of the installation ring frame 1 is completed, thereby realizing the basic positioning of the entire lightning protection device. The support frame 2 at the top of the installation ring frame 1 is used to support the top ring 3, so that the top ring 3 can be kept at the preset height position, providing a stable benchmark for the subsequent installation and operation of various components.

[0036] After installation, when dust and debris adhere to the surface of the lightning rod body 5 and need cleaning, the cleaning operation begins. At this time, the motor drive mechanism 7 is activated. The fixed arm 71 in the motor drive mechanism 7 provides installation support for the fixed base 73. The fixed base 73 carries the drive motor 74, enabling the drive motor 74 to maintain a stable installation posture. When the drive motor 74 is running, its output end drives the first gear 75 to rotate. Since the first gear 75 meshes with the first rack 72, the rotation of the first gear 75 can be converted into the linear lifting and lowering motion of the first rack 72, thereby driving the lightning rod base 4 to move down along the inner side of the top ring 3. When the lightning rod base 4 moves down, it will drive the cleaning mechanism 6 in conjunction. The outer ring 61 of the cleaning mechanism 6 is fixed to the lightning rod base 4 by the connecting block 62 and screws, which can transmit the lifting and lowering power of the lightning rod base 4 to the transmission component 6. 3; The sliding groove 631 of the transmission component 63 cooperates with the lifting slide plate 632, so that the lightning rod base 4 can slide stably along the inner side of the top ring 3. At the same time, the lifting slide plate 632 will move down with the lightning rod base 4 and drive the second rack 634 to move down synchronously. The second rack 634 meshes with the second gear 636. When the second rack 634 moves down, it will drive the second gear 636 to rotate, which in turn drives the rotating shaft 635 to rotate. The rotation of the rotating shaft 635 will drive the cleaning component 64 to move. The mounting frame 641 of the cleaning component 64 rotates with the rotating shaft 635. The mounting sleeve 642 on the outside of the mounting frame 641 is used to insert the bent mounting rod 643. The two can be fixed by the hand-tightening mounting screw 645, so that the cleaning brush plate 644 at the outer end of the bent mounting rod 643 can rotate with the mounting frame 641 and gradually fit against the outer surface of the lightning rod body 5.

[0037] After the cleaning brush plate 644 is attached to the lightning rod body 5, the wind-driven mechanism 9 starts to drive the lightning rod body 5 to rotate. The bent connecting arm 921 of the wind-driven mechanism 9 provides installation support for the round seat 922. The round seat 922 carries the second synchronous pulley 923 and allows the second synchronous pulley 923 to rotate around the top. When the external wind force acts on the vertical axis wind turbine rotor 924, it will drive the rotor to rotate, which in turn drives the second synchronous pulley 923 to rotate. The second synchronous pulley 923 transmits power to the first synchronous pulley 914 through the synchronous belt. The first synchronous pulley 914 drives the third gear 913 to rotate. The third gear 913 is stably supported by the bent connecting rod 911, and the third gear 913 meshes with the gear ring 912, so that the rotation of the third gear 913 can drive the gear ring 912 and the lightning rod body 5 to rotate. At this time, the cleaning mechanism 6 remains stationary. The rotating lightning rod body 5 and the stationary cleaning brush plate 644 generate relative motion, which can realize the brushing and cleaning of the outer surface of the lightning rod body 5. If cleaning is carried out on a rainy day, rainwater can wash the surface of the lightning rod body 5, which, together with the brushing action of the cleaning brush plate 644, can further improve the cleaning effect.

[0038] After cleaning, the lightning protection operation begins. The drive motor 74 reverses direction, causing the first gear 75 to rotate in the opposite direction, which in turn drives the first rack 72 to move upward. This causes the lightning rod base 4 to move upward along the inner side of the top ring 3. As the lightning rod base 4 moves upward, it drives the lifting slide plate 632 to move upward synchronously through the outer ring 61. The lifting slide plate 632 drives the second rack 634 to move upward and causes the second gear 636 to rotate in the opposite direction, which in turn drives the rotating shaft 635 to rotate in the opposite direction. Finally, it causes the mounting frame 641 and the cleaning brush plate 644 to rotate outward and downward, realizing the unfolding of the cleaning mechanism 6. At the same time, the upward movement of the lightning rod base 4 will drive the lightning rod body 5 to move upward, causing the lightning rod body 5 to detach from the various parts. The inner side of the cleaning brush plate 644 is in a preset lightning protection working position. At this time, the grounding wire 8 at the bottom of the lightning rod base 4 is electrically connected to the lightning rod body 5, which can conduct the lightning current received by the lightning rod body 5 into the ground. The top ring 3, support frame 2, fixed base frame 73 and other structures are made of insulating materials, which can prevent the lightning current from being conducted to the ancient building through these structures, ensuring that the lightning current only forms a conductive path through the lightning rod body 5 and the grounding wire 8, thereby realizing the lightning protection function. This technical solution, through the coordinated action of the cleaning mechanism 6, the wind-driven mechanism 9, and the motor-driven mechanism 7, can periodically brush and clean the outer surface of the lightning rod body 5. The cleaning brush plate 644 can The system directly removes attached dust, leaves, dead leaves, household garbage, and other debris, preventing the formation of a dirt layer and ensuring the outer surface of the lightning rod body 5 remains clean to guarantee its stable conductivity and thus ensure lightning protection effectiveness. The cleaning power comes from natural outdoor wind, requiring no additional electricity input, which is suitable for outdoor ancient building areas, reducing energy consumption. Furthermore, the wind-driven component 92 has a simple structure, stable operation, and requires no frequent maintenance. The transmission component 63 features a convex structure for the slide groove 631 and the lifting plate 632, preventing the lifting plate 632 from disengaging from the slide groove 631 during sliding, ensuring the stability of the meshing between the second rack 634 and the second gear 636. The synchronous belt drive and gear... The meshing transmission of the wheels ensures precise power transmission, making the rotation angle of the cleaning mechanism 6 and the rotation speed of the lightning rod body 5 controllable, further improving the cleaning effect. The lifting and lowering of the lightning rod base 4 is driven by the motor drive mechanism 7, realizing the orderly switching between cleaning and lightning protection, preventing the cleaning mechanism 6 from being damaged during a lightning strike, and ensuring that the lightning rod body 5 is in the optimal lightning protection position without being blocked or interfered with. The bent mounting rod 643 and the mounting sleeve 642 in the cleaning component 64 are fixed by the hand-tightening mounting screw 645, which can be disassembled and assembled without the need for special tools, making it easy to replace or clean the cleaning brush plate 644 and ensuring the long-term cleaning effect of the cleaning mechanism.The combination of the mounting plate 10 and the countersunk hole ensures the stable installation of the device. The countersunk hole can prevent the fasteners from being exposed and affecting the appearance of the ancient building. The selection of various support structures and insulation materials ensures that the device will not damage the structure of the ancient building after installation. The protective shielding cover on the outside of the drive motor 74 is composed of a lightning protection layer, an electromagnetic shielding layer, and an insulation isolation layer, which can prevent the drive motor 74 from being interfered with or damaged by lightning, ensure the stable operation of the motor drive mechanism 7, and thus ensure the linkage accuracy of the cleaning mechanism 6.

[0039] This technical solution uses an STM32F103RCT6 microcontroller as the supplementary controller, installed inside the protective shield of the motor drive mechanism 7. The main electronic components and their specifications are as follows: The drive motor 74 is a 57BYG250H stepper motor with a rated voltage of 24V, a rated current of 3A, and an output torque of 0.8N·m. An RV30 gearbox reducer with a reduction ratio range of 5-100 is installed at the motor to increase torque and regulate speed. The motor is equipped with an E6B2-CWZ6C encoder with a resolution of 1000 lines, enabling flexible rotation adjustment and stepless speed regulation. Additionally, a rain sensor (YL-83 type) can be installed during application to detect rain. Mounted on the mounting ring 1, support frame 2, or top ring 3, with a rated voltage of 5V and an operating current of less than 10mA; the current sensor is selected as ACS712-20A, with a rated detection current range of 0-20A, used to monitor the lightning current of the grounding wire 8; the controller is powered by a DC24V switching power supply, with an input voltage range of AC110-220V and an output current of 5A, connected to the drive motor 74, encoder, rain sensor, and current sensor via power lines; the circuit connection is as follows: the I / O ports of the STM32F103RCT6 controller are connected to the drive module of the 57BYG250H stepper motor, the signal output terminal of the E6B2-CWZ6C encoder, and the YL-83 rain sensor respectively. The signal output terminal is connected to the signal output terminal of the ACS712-20A current sensor. The controller establishes communication with each actuator via the CAN bus. The drive module of the drive motor 74 receives the pulse signal from the controller and controls the forward and reverse rotation and speed of the motor. The encoder feeds back the motor rotation angle signal to the controller to form a closed-loop control. The rain sensor transmits the rain detection signal to the controller. The controller determines whether to start the cleaning operation and rainwater-coordinated cleaning mode based on this signal. The current sensor feeds back the current signal of the grounding wire 8 to the controller. The display screen shows the motor running status, sensor detection data, cleaning operation progress, and lightning protection current parameters in real time. During use, L can be installed at the lifting path of the lightning rod base 4 according to specific application requirements. An M393 infrared proximity sensor is used to detect the lifting limit position of the lightning rod base 4 to prevent excessive lifting and lowering that could cause structural damage. An FSR402 pressure sensor is installed at the contact point between the cleaning brush plate 644 and the lightning rod body 5 to detect the contact pressure of the cleaning brush plate 644, ensuring cleaning effectiveness while preventing excessive pressure from damaging the lightning rod body 5. An HC-SR501 human infrared sensor is installed at the fixing point of the device mounting ring 1 to monitor whether there is human activity in the installation and maintenance area, preventing safety accidents during operation. All these sensors are connected to an STM32F103RCT6 controller via wires, which provides power and receives their detection signals to enable automatic operation or manual assistance of the device.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
