Technical Field
[0001] This utility model relates to the technical field of lightning protection devices, specifically a lightning protection device for wind farms. Background Technology
[0002] A site for wind power generation is called a wind farm. Wind farms are typically built in remote plains areas with few obstructions, making them more susceptible to lightning strikes during thunderstorms. Therefore, it is necessary to design appropriate lightning protection devices to protect the wind power generation components.
[0003] However, commonly used lightning protection devices are usually fixed and cannot be adjusted. They cannot adjust the distance to the protected equipment as needed, which affects the installation or the subsequent protection effect and results in poor versatility. Therefore, we propose a lightning protection device for wind farms. Utility Model Content
[0004] The purpose of this invention is to provide a lightning protection device for wind farms to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A lightning protection device for wind farms includes a C-shaped plate, a movable base, a mounting base, a lightning rod body, a guide cable, an adjustment mechanism, and a fixing mechanism. The movable base is movably mounted on the top of the C-shaped plate, the mounting base is fixedly mounted on the top of the movable base, the lightning rod body is fixedly mounted on the top of the mounting base, the guide cable is fixedly mounted on one side of the movable base, the adjustment mechanism is provided at the bottom of the movable base, and the fixing mechanism is provided on one side of the C-shaped plate.
[0006] The adjustment mechanism includes a lead screw, a rotating disk, a slot, a block, a telescopic groove, a spring, and a rotating rod. The lead screw is rotatably connected between opposite sides of the C-shaped plate. The lead screw passes through and is threadedly connected to the movable seat. A rotating disk is rotatably connected to one side of the C-shaped plate. The rotating disk and one end of the lead screw are fixedly connected.
[0007] The rotating disk has several slots on its outer edge, and each slot matches one end of a locking block. The C-shaped plate has a telescopic groove on one side, and a spring is fixedly installed inside the telescopic groove. One end of the spring is fixedly connected to the locking block, and the locking block matches the telescopic groove. A rotating rod is fixedly installed on one side of the rotating disk.
[0008] The adjustment mechanism further includes a handle, a slide groove, a limiting groove, a limiting block, and a bottom block. One end of the rotating rod is fixedly provided with a handle, and the top of the C-shaped plate is provided with a slide groove.
[0009] The slide groove has limit grooves on both sides of its inner wall, and a limit block is slidably connected inside the limit groove. A bottom block is fixedly installed at one end of the limit block, and the top of the bottom block is fixedly connected to the bottom of the movable seat.
[0010] The fixing mechanism includes a fixing plate, a threaded groove, and bolts, with the fixing plate fixedly disposed on one side of the C-shaped plate.
[0011] The C-shaped plate has several threaded grooves on one side, and bolts are threaded into the grooves.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. A lightning protection device for wind farms, wherein a movable base is movably installed on the top of a C-shaped plate, and the top of the base is fixed to the lightning rod body via a mounting base to ensure that the lightning rod body stands firmly. The guide cable on one side of the movable base serves as a lightning current conduction channel. When the lightning rod body attracts lightning, the lightning current can be quickly conducted into the ground along the guide cable, fundamentally avoiding the impact of lightning on wind farm equipment. When the lightning rod's protective position needs to be adjusted, precise control can be achieved by operating the adjustment mechanism: rotating the handle at one end of the rotating rod causes the rotating rod and the rotating disk on one side of the C-shaped plate to rotate synchronously. Since the rotating disk and the opposite side of the C-shaped plate are fixedly connected by a screw, the screw rotates accordingly. Because the screw passes through and is threadedly connected to the moving seat, the rotation of the screw is converted into the linear movement of the moving seat along the screw. At the same time, the bottom block of the moving seat slides along the groove on the top of the C-shaped plate, and the limiting grooves on both sides of the groove slide and the limiting blocks on the bottom block, effectively limiting the offset of the moving seat and ensuring that the lightning rod body moves smoothly to the target position along the preset trajectory. The distance can be adjusted according to the size of different equipment, thereby improving the versatility of the device.
[0013] 2. This lightning protection device for wind farms uses a fixing plate fixed to one side of a C-shaped plate as a connecting medium. Bolts are screwed into the threaded grooves on the corresponding side of the C-shaped plate, and the threads of the bolts and the threaded grooves engage tightly, firmly fixing the C-shaped plate and the entire device to the wind farm towers and other load-bearing structures, preventing the device from loosening or shifting due to external environmental influences. After the adjustment mechanism completes the position adjustment of the lightning rod body, the locking function of the adjustment mechanism is activated. The spring in the telescopic groove on one side of the C-shaped plate is in a naturally extended state, and its elastic force pushes the locking block to move towards the rotating disk, so that one end of the locking block is embedded in the locking groove on the outer edge of the rotating disk, forming a mechanical lock. This locking structure can effectively prevent the rotating disk and the connected screw from rotating under the action of external forces such as strong winds and lightning strikes, thereby ensuring that the relative position of the moving seat, the mounting seat and the lightning rod body remains constant, ensuring that the lightning protection device continuously and stably performs its protective function. Through the above design, the ease of use of the device is improved. Attached Figure Description

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.
[0017] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution: A lightning protection device for wind farms includes a C-shaped plate 1, a movable base 2, a mounting base 3, a lightning rod body 4, a guide cable 5, an adjustment mechanism 6, and a fixing mechanism 7. The movable base 2 is movably mounted on the top of the C-shaped plate 1, the mounting base 3 is fixedly mounted on the top of the movable base 2, the lightning rod body 4 is fixedly mounted on the top of the mounting base 3, the guide cable 5 is fixedly mounted on one side of the movable base 2, the adjustment mechanism 6 is provided at the bottom of the movable base 2, and the fixing mechanism 7 is provided on one side of the C-shaped plate 1.
[0018] The C-shaped plate serves as the core support frame of the device, providing an installation base for the movable seat 2, adjustment mechanism 6, and fixing mechanism 7, bearing the weight of the entire device. At the same time, it provides guiding space for the movement of the movable seat 2 through the top slide groove 609, ensuring that the components are assembled in an orderly manner and work together.
[0019] The adjusting mechanism 6 includes a lead screw 601, a rotating disk 602, a slot 603, a locking block 604, a telescopic groove 605, a spring 606, and a rotating rod 607. The lead screw 601 is rotatably connected between opposite sides of the C-shaped plate 1. The lead screw 601 passes through and is threadedly connected to the movable seat 2. The rotating disk 602 is rotatably connected to one side of the C-shaped plate 1. One end of the rotating disk 602 is fixedly connected to one end of the lead screw 601. Several slots 603 are provided on the outer edge of the rotating disk 602. One end of the slot 603 matches one end of the locking block 604. A telescopic groove 605 is provided on one side of the C-shaped plate 1. A spring 606 is fixedly installed inside the telescopic groove 605. One end of the spring 606 is fixedly connected to the locking block 604. The locking block 604 matches the telescopic groove 605. One side of the rotating disk 602 is fixedly connected to the sliding seat 2. The adjustment mechanism 6 includes a rotating rod 607, a handle 608, a slide groove 609, a limiting groove 610, a limiting block 611, and a bottom block 612. One end of the rotating rod 607 is fixedly provided with a handle 608. The top of the C-shaped plate 1 is provided with a slide groove 609. The inner walls of both sides of the slide groove 609 are provided with limiting grooves 610. The limiting block 611 is slidably connected inside the limiting groove 610. One end of the limiting block 611 is fixedly provided with a bottom block 612. The top of the bottom block 612 is fixedly connected to the bottom of the movable seat 2. The fixing mechanism 7 includes a fixing plate 701, a threaded groove 702, and a bolt 703. The fixing plate 701 is fixedly provided on one side of the C-shaped plate 1. Several threaded grooves 702 are provided on one side of the C-shaped plate 1. The bolts 703 are threadedly connected inside the threaded grooves 702.
[0020] The locking block 604 is slidably adapted to the telescopic groove 605, and one end is fixed to the spring 606. Under the elastic force of the spring 606, it can extend out of the telescopic groove 605 and be embedded in the locking groove 603 of the rotating disk 602 to achieve locking. When adjustment is required again, the external force pulls the locking block 604 to compress the spring 606, which can disengage it from the locking groove 603 and release the lock.
[0021] In this embodiment, a lightning protection device for wind farms is used in which the movable base 2 is movably installed on the top of the C-shaped plate, and its top is fixed to the lightning rod body 4 via the mounting base 3, ensuring that the lightning rod body 4 stands stably. The guide cable 5 on one side of the movable base 2 serves as a lightning current discharge channel. When the lightning rod body 4 attracts lightning, the lightning current can be quickly discharged into the ground along the guide cable 5, fundamentally avoiding the impact of lightning on wind farm equipment. When the lightning rod's protective position needs to be adjusted, precise control can be achieved by operating the adjustment mechanism 6: rotating the handle 608 at one end of the rotating rod 607 causes the rotating rod 607 and the rotating disk 602 on one side of the C-shaped plate to rotate synchronously. Since the rotating disk 602 and the opposite side of the C-shaped plate are fixedly connected by the screw 601, the screw 601 rotates accordingly. Since the screw 601 passes through and is threadedly connected to the moving seat 2, the rotation of the screw 601 is converted into the linear movement of the moving seat 2 along the screw 601. At the same time, the bottom block 612 of the moving seat 2 slides along the slide groove 609 on the top of the C-shaped plate, and the limiting grooves 610 on both sides of the inner wall of the slide groove 609 slide and adapt to the limiting blocks 611 on the bottom block 612, effectively limiting the offset of the moving seat 2 and ensuring that the lightning rod body 4 moves smoothly to the target position along the preset trajectory. The distance can be adjusted according to the size of different equipment, thereby improving the versatility of the device. The fixing plate 701 fixed on one side of the C-shaped plate serves as a connection medium. The bolt 703 is screwed into the threaded groove 702 on the corresponding side of the C-shaped plate. The bolt 703 and the threaded groove 702 are tightly engaged, which can firmly fix the C-shaped plate and the entire device to the wind farm tower and other load-bearing structures, preventing the device from loosening or shifting due to the influence of the external environment. After the adjustment mechanism 6 completes the position adjustment of the lightning rod body 4, the locking function of the adjustment mechanism 6 is immediately activated. The spring 606 in the telescopic groove 605 on one side of the C-shaped plate is in a naturally extended state. Its elastic force pushes the locking block 604 to move towards the rotating disk 602, so that one end of the locking block 604 is embedded in the locking groove 603 on the outer edge of the rotating disk 602, forming a mechanical lock. This locking structure can effectively prevent the rotating disk 602 and the connected screw 601 from rotating under the action of external forces such as strong winds and lightning strikes, thereby ensuring that the relative position of the moving seat 2, the mounting seat 3 and the lightning rod body 4 remains constant, ensuring that the lightning protection device can continuously and stably perform its protective function. Through the above design, the ease of use of the device is improved.
