Abstract
Description
Technical Field
[0001] This utility model relates to the field of lightning protection equipment technology, specifically to a non-direct lightning strike dissipation protection device. Background Technology
[0002] In the field of modern building and electrical equipment protection, lightning protection technology has always been a key line of defense for ensuring safety. Its core is an integrated system that intercepts, diverts, and discharges lightning current, effectively resisting damage to buildings and their internal equipment from direct lightning strikes and lightning electromagnetic pulses. In addition to traditional lightning rods, new lightning protection devices, represented by TM-CPD, break through the traditional concept of "diverting lightning to the ground." Based on the "upper neutralization, lower blocking" lightning protection "flashback" technology, they construct a three-dimensional protection system that prevents downward lightning leaders from entering the protected area, achieving zero direct lightning strike damage.
[0003] Existing lightning protection devices mostly employ the corona needle tip discharge effect to actively neutralize the charge of lightning clouds and reduce the regional electric field intensity. Simultaneously, they utilize a high-voltage umbrella skirt structure composed of insulating materials and conductive layers to form an electric field barrier, blocking the lightning leader's path. This synergistic mechanism not only eliminates the threat of direct lightning strikes but also effectively avoids secondary disasters caused by lightning induction, fundamentally dismantling the conditions for lightning formation. However, current devices generally use bolted installation to support poles, resulting in a lack of angle adjustment functionality. In complex terrains such as slopes and building edges, fixed-angle corona needles struggle to adapt to changes in the electric field, limiting the neutralization range and significantly increasing the risk of lightning formation. When the high-voltage umbrella skirt protection angle is less than 70°, the electric field barrier will have coverage blind spots, creating conditions for lightning leaders to bypass and intrude. In special scenarios such as high-voltage transmission lines, fixed-angle umbrella skirts cannot match the conductor layout, easily causing localized protection failures and threatening the safe and stable operation of the power system.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Reference Figures 1 to 4 The non-contact direct lightning strike dissipation protection device shown in this embodiment of the utility model includes a base 1. A pair of rotating shafts 2 are rotatably arranged on the inner wall of the base 1. An adjustment component 3 is provided at one end of the rotating shaft 2, and a mounting plate 4 is fixedly connected to the other end of the rotating shaft 2. A mounting seat 5 is installed on the top of the mounting plate 4, and a lightning protection component 6 is provided on the top of the mounting seat 5. A support rod 7 is bolted to the bottom of the base 1.
[0020] The base 1 is fixedly installed on the top of the support rod 7 by bolts. The mounting seat 5 is fixed on the bottom of the lightning protection component 6. The mounting seat 5 is installed inside the mounting plate 4. The rotating shaft 2 is welded to both ends of the mounting plate 4. The rotating shaft 2 rotates on the base 1, which drives the mounting plate 4 to rotate. The angle of the mounting plate 4 is adjusted by the adjusting component 3, thereby adjusting the tilt angle of the lightning protection component 6.
[0021] Preferably, the adjustment component 3 includes a fixed plate 31 fixedly disposed at one end of the rotating shaft 2, a T-bolt 32 screwed into the fixed plate 31, and movable grooves 33 that cooperate with the T-bolt 32 are provided on both sides of the base 1. The outer side of the T-bolt 32 slides in the movable groove 33, and a fixing nut 34 is screwed onto the T-bolt 32.
[0022] When the rotating shaft 2 drives the mounting plate 4 to rotate, the fixing plate 31 at one end of the rotating shaft 2 rotates against the side of the base 1, and drives the T-bolt 32 inside the fixing plate 31 to slide in the moving groove 33, guiding the fixing plate 31. Finally, the T-bolt 32 is positioned by the fixing nut 34, thereby fixing the position of the rotating shaft 2 and improving the stability of the lightning protection component 6.
[0023] The lightning protection component 6 includes a fixed rod 61 fixedly installed on the top of the mounting base 5. Multiple high-voltage umbrella skirts 62 are installed on the outside of the fixed rod 61. A connecting ball 63 is fixedly connected to the top of the fixed rod 61. Multiple corona needles 64 are provided on the outer wall of the connecting ball 63.
[0024] The corona current is released through the discharge effect at the tip of the corona needle 64, which actively neutralizes the charge of the lightning cloud above the protected area, reduces the local electric field intensity, and decreases the probability of lightning formation. A high-voltage electric field barrier is formed on the surface of the high-voltage umbrella skirt 62, blocking the downward lightning leader channel from entering the protected area. The electric field distortion effect at the edge of the high-voltage umbrella skirt 62 can interfere with the lightning leader path, guiding it to detour or dissipate in advance. The corona needle 64 continuously releases ions to neutralize the cloud charge, while the high-voltage umbrella skirt 62 forms a local protective barrier through the high-voltage electric field. The dual effect significantly weakens the lightning energy. When the downward lightning leader approaches the protected area, it cannot form an effective discharge channel due to electric field interference and eventually detours or dissipates on its own. It has the ability to avoid becoming a lightning contact point through dissipation and blocking technology, and eliminate the risk of electromagnetic pulse and ground potential backlash caused by lightning strikes.
[0025] Preferably, the top of the mounting plate 4 has a mounting groove 8, and the outer side of the mounting base 5 is engaged with the inner wall of the mounting groove 8.
[0026] Positioning blocks 9 are fixedly connected to both sides of the mounting base 5, and the number of positioning blocks 9 is set to two.
[0027] Both sides of the mounting groove 8 are connected to the positioning groove 10, and the inner wall of the positioning groove 10 is engaged with the outer side of the positioning block 9.
[0028] The inner wall of the positioning block 9 is threaded with a positioning bolt 11. The outer side of the positioning bolt 11 is threaded with the threaded hole 12 in the positioning groove 10. A knob 13 is fixedly connected to the top of the positioning bolt 11.
[0029] The mounting base 5 is inserted into the mounting groove 8 at the top of the mounting plate 4, and the positioning block 9 is inserted into the positioning groove 10 to initially position the mounting base 5 and the positioning block 9. Then, the positioning bolt 11 is threadedly connected to the threaded hole 12 to fix the positioning block 9, thereby facilitating the installation and removal of the mounting base 5 and the installation and removal of the lightning protection component 6.
[0030] The working principle of this utility model is as follows:
[0031] The base 1 is bolted to the top of the support rod 7, and the mounting seat 5 is fixed to the bottom of the lightning protection component 6. The mounting seat 5 is installed inside the mounting plate 4. The rotating shaft 2 is welded to both ends of the mounting plate 4. The rotating shaft 2 rotates on the base 1, causing the mounting plate 4 to rotate. When the rotating shaft 2 rotates the mounting plate 4, the fixing plate 31 at one end of the rotating shaft 2 rotates against one side of the base 1, causing the T-bolt 32 inside the fixing plate 31 to slide in the moving groove 33, guiding the fixing plate 31. Finally, the fixing nut 34 positions the T-bolt 32, thereby fixing the position of the rotating shaft 2 and improving the stability of the lightning protection component 6. The corona current is released through the tip discharge effect of the corona needle 64, actively neutralizing the protected area. The lightning cloud charge above the domain reduces the local electric field strength and decreases the probability of lightning formation. The high-voltage umbrella skirt 62 forms a high-voltage electric field barrier on its surface, blocking the downward lightning leader channel from entering the protected area. The electric field distortion effect at the edge of the high-voltage umbrella skirt 62 can interfere with the lightning leader path, guiding it to detour or dissipate in advance. The corona needle 64 continuously releases ions to neutralize the cloud charge, while the high-voltage umbrella skirt 62 forms a local protective barrier through the high-voltage electric field. The dual effect significantly weakens the lightning energy. When the downward lightning leader approaches the protected area, it cannot form an effective discharge channel due to electric field interference and eventually detours or dissipates on its own. It has the ability to avoid becoming a lightning strike point through dissipation and blocking technology, and eliminate the risk of electromagnetic pulse and ground potential backlash caused by lightning strikes.
