Technical Field
[0001] This utility model belongs to the technical field of lightning protection devices, specifically relating to a novel lightning protection device. Background Technology
[0002] Lightning protection devices for buildings are generally divided into two main categories: external lightning protection devices and internal lightning protection devices. External lightning protection devices consist of lightning rods, down conductors, and grounding devices, which are traditional lightning protection devices.
[0003] A patent document with publication number CN210780033U discloses a "lightning protection device for power distribution lines," comprising a mounting bracket and a lightning arrester. The lightning arrester is fixedly connected to the upper surface of the mounting bracket, and a threaded connecting rod is fixedly connected to the upper surface of the lightning arrester. A rotating block is threadedly connected to the outer surface of the threaded connecting rod, and a connecting rod is movably connected to the outer surface of the rotating block via a rotating shaft. This application utilizes a dust-removing wiper to install the device at the power distribution line. A rotating fan, under the influence of high-altitude wind, drives a first trapezoidal rotating block to rotate via a connecting rod, which in turn drives a second trapezoidal rotating block to rotate. This causes the threaded rod to move up and down. Through the interaction of the rotating gear and the connecting gear, the rotating block rotates on the surface of the threaded connecting rod, i.e., the rotating block moves up and down on the outer surface of the threaded connecting rod. This allows the dust-removing wiper, driven by the connecting rod, to clean the outer surface of the lightning arrester. This effectively reduces the pollution and safety accidents caused by the lightning arrester's surface becoming wetted with dust, which could drastically increase conductivity and thus ensure the safety of the device during use.
[0004] This device removes dust by wiping the surface of the surge protector with a duster. While it can clean the dust off the surface of the surge protector, this contact cleaning method poses a safety hazard. When the surge protector attracts lightning, it generates tens of thousands of volts of high voltage inside. If the duster comes into contact with liquid and becomes wet, it will conduct electricity, thereby generating a huge current, which poses a safety hazard. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a new type of lightning protection device. This device uses a wind collector to gather the airflow generated by the rotating fan blades for contactless dust removal, which is safer and more reliable. At the same time, an auxiliary mechanism can adjust the direction of the airflow to ensure thorough cleaning.
[0006] The present invention provides a novel lightning protection device, comprising a lightning protector and a cleaning mechanism. A base is fixedly installed at the bottom of the lightning protector, and an L-plate is fixedly installed on the base. The cleaning mechanism includes a rotating rod, a wind collector, a rotating shaft, a wind cup, fan blades, and a transmission assembly. The rotating rod rotatably passes through the top of the L-plate, the wind cup is installed at the top of the rotating rod, the rotating shaft is rotatably inserted into the L-plate, the fan blades are fixedly installed at the end of the rotating shaft near the lightning protector, the wind collector is fixedly installed on the L-plate and covers the fan blades, and the transmission assembly is used to drive the rotating shaft and the rotating rod so that the rotation of the rotating rod can drive the rotating shaft to rotate synchronously.
[0007] Furthermore, the transmission assembly includes a large bevel gear and a small bevel gear. The large bevel gear is fixedly mounted on the rotating rod, and the small bevel gear is fixedly installed on one end of the rotating shaft near the rotating rod and meshes with the large bevel gear.
[0008] Furthermore, it also includes an auxiliary mechanism for adjusting the direction of airflow from the air collector hood. The auxiliary mechanism includes a guide hood, a connecting rod, an L-rod, and a drive structure. The guide hood is rotatably mounted at the air outlet of the air collector hood. The L-rod slides through the L-plate. One end of the connecting rod is rotatably connected to the guide hood and the other end is rotatably connected to the L-rod.

[0009] Furthermore, the drive structure includes a sleeve rod and an eccentric wheel. The eccentric wheel is fixedly mounted on the rotating rod, and the sleeve rod is fixedly connected to one end of the L rod near the rotating rod. The sleeve rod is sleeved on the eccentric wheel.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1. This new type of lightning protection device uses the wind power at high altitude to blow the wind cup, which can drive the rotating rod to rotate. At the same time, the large bevel gear, small bevel gear, rotating shaft, fan blade, and wind collector cover can blow away the dust on the surface of the lightning protection device. The dust on the surface of the lightning protection device can be cleaned without touching it, thereby avoiding the occurrence of safety accidents.
[0012] 2. This new type of lightning protection device can drive the guide shroud to swing up and down repeatedly by rotating the rotating rod in conjunction with the eccentric wheel, sleeve rod, L-rod, and connecting rod. The reciprocating swing of the guide shroud can guide the airflow blown out by the air collecting shroud, thereby expanding the coverage of the airflow and thus expanding the range of airflow dust removal, further improving the dust removal effect.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer and more understandable, the technical solutions of this utility model will be further described in detail below with reference to the accompanying drawings of the embodiments of this utility model.
[0020] Reference Figures 1 to 5 The present invention discloses a novel lightning protection device, comprising a lightning protector 1 and a cleaning mechanism 4. A base 2 is fixedly installed at the bottom of the lightning protector 1, and an L-plate 3 is fixedly installed on the base 2. The cleaning mechanism 4 includes a rotating rod 41, a wind collector 43, a rotating shaft 42, a wind cup 44, a fan blade 47, and a transmission assembly. The rotating rod 41 rotatably passes through the top of the L-plate 3, the wind cup 44 is installed at the top of the rotating rod 41, the rotating shaft 42 is rotatably inserted into the L-plate 3, the fan blade 47 is fixedly installed at the end of the rotating shaft 42 near the lightning protector 1, the wind collector 43 is fixedly installed on the L-plate 3 and covers the fan blade 47, and the transmission assembly is used to drive the rotating shaft 42 and the rotating rod 41 to rotate synchronously. The transmission assembly includes a large bevel gear 45 and a small bevel gear 46. The large bevel gear 45 is fixedly mounted on the rotating rod 41, and the small bevel gear 46 is fixedly mounted on the end of the rotating shaft 42 near the rotating rod 41 and meshes with the large bevel gear 45.
[0021] The wind cup 44 is installed at the top of the rotating rod 41, which is relatively high. The wind force at high altitude blows the wind cup 44 to make it rotate, which in turn drives the rotating rod 41 to rotate. When the rotating rod 41 rotates, it drives the large bevel gear 45 to rotate synchronously. The rotating shaft 42 rotates through the L plate 3, and the small bevel gear 46 is installed on the rotating shaft 42. The small bevel gear 46 meshes with the large bevel gear 45, so when the large bevel gear 45 rotates, it can drive the rotating shaft 42 to rotate, which in turn makes the fan blade 47 rotate and generate airflow. The wind collector shroud 43 covers the fan blade 47. The shape of the wind collector shroud 43 is open at both ends. The opening is larger at the end near the rotating rod 41 and smaller at the end near the surge protector 1. The wind collector shroud 43 is concentric with the rotating shaft 42. Therefore, the wind collector shroud 43 can reduce the range of airflow blown out by the fan blade 47 and increase the wind pressure, thereby blowing away dust and other debris on the surface of the surge protector 1 through high-speed airflow.
[0022] The novel lightning protection device of this utility model also includes an auxiliary mechanism 5 for adjusting the direction of the airflow from the air collecting hood 43. The auxiliary mechanism 5 includes a guide hood 51, a connecting rod 55, an L-rod 53, and a drive structure. The guide hood 51 is rotatably mounted at the air outlet of the air collecting hood 43. The L-rod 53 slides through the L-plate 3. One end of the connecting rod 55 is rotatably connected to the guide hood 51, and the other end is rotatably connected to the L-rod 53. The drive structure can synchronously drive the L-rod 53 to slide in the L-plate 3 when the rotating rod 41 rotates. The drive structure includes a sleeve rod 54 and an eccentric wheel 52. The eccentric wheel 52 is fixedly mounted on the rotating rod 41, and the sleeve rod 54 is fixedly connected to the end of the L-rod 53 near the rotating rod 41. The sleeve rod 54 is sleeved on the eccentric wheel 52.
[0023] The air guide shroud 51 is cone-shaped with openings at both ends. It guides the airflow blown out of the air collecting shroud 43. When the rotating rod 41 rotates, it can directly drive the eccentric wheel 52 to rotate. Since the sleeve rod 54 is sleeved on the eccentric wheel 52, the rotation of the eccentric wheel 52 interferes with the sleeve rod 54, causing the sleeve rod 54 to reciprocate. This, in turn, drives the L rod 53 to slide back and forth in the L plate 3. Since one end of the connecting rod 55 is rotatably connected to the air guide shroud 51 and the other end is rotatably connected to the L rod 53, and the air guide shroud 51 is rotatably installed at the air outlet of the air collecting shroud 43, the reciprocating sliding of the L rod 53 can drive the air guide shroud 51 to pitch and reciprocate at the air outlet of the air collecting shroud 43 through the transmission of the connecting rod 55. This allows the clean airflow to blow back and forth from top to bottom on the surge protector 1.
[0024] In summary, the working principle of this utility model is as follows: the wind cup 44 is driven by the wind force at high altitude, which drives the rotating rod 41 to rotate. The rotation of the rotating rod 41 drives the large bevel gear 45 to rotate synchronously. The rotation of the large bevel gear 45, in conjunction with the small bevel gear 46 meshing with it, drives the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 drives the fan blades 47 to rotate synchronously. The rotation of the fan blades 47 blows air towards the surge protector 1. At this time, the air collecting cover 43 can reduce the range of the air blown by the fan blades 47, so that the air blown by the fan blades 47 can be concentrated and blown towards the outer wall of the surge protector 1. Furthermore, the air pressure increases due to the narrowing of the air outlet by the air collecting cover 43, thereby increasing the airflow blown by the fan blades 47. At this time, the airflow blown by the fan blades 47, together with the air collecting cover 43, can blow away the dust on the surface of the surge protector 1. The dust on the surface of the surge protector 1 can be cleaned without touching it, thereby preventing the occurrence of safety accidents.
[0025] As the rotating rod 41 rotates, it drives the eccentric wheel 52 to rotate synchronously. As the eccentric wheel 52 rotates, it pushes and pulls the sleeve rod 54 back and forth, causing the sleeve rod 54 to push and pull the L rod 53 back and forth. This causes the L rod 53 to slide back and forth on the L plate 3. At the same time, the L rod 53 pushes and pulls the connecting rod 55 back and forth, causing the connecting rod 55 to push and pull the guide shroud 51 back and forth. This causes the guide shroud 51 to move up and down at the air outlet of the air collecting shroud 43, thereby guiding the airflow blown out by the air collecting shroud 43. This allows the airflow blown by the air collecting shroud 43 towards the lightning protection device 1 to be adjusted up and down, thereby expanding the coverage area of the airflow and thus expanding the range of airflow dust removal, further improving the dust removal effect.
