Description

Technical Field

[0001] The utility model belongs to the technical field of grounding devices, and in particular relates to a lightning protection grounding device. Background Art

[0002] Lightning protection grounding devices are important facilities that protect buildings and their internal equipment from lightning strikes and related currents. Their main function is to introduce the high voltage and current generated by lightning into the ground, thereby reducing damage to buildings and their equipment.

[0003] However, in actual use, personnel in this field have found that most existing grounding devices are welded between the grounding rod and the connecting wire. When pulled for a long time, the connecting wire and the grounding rod are easily disconnected and fall off, thereby affecting the grounding conductivity and inconvenience for users. In addition, most existing grounding wires are exposed, and outdoor rats are more likely to bite the grounding wires, thereby affecting the normal use of the device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a lightning protection grounding device, which has the advantages of preventing the grounding wire from being disconnected and falling off from the grounding rod and preventing rats from chewing the wire.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a lightning protection grounding device, comprising a base plate, four correspondingly distributed fixed cones movably plugged into the interior of the base plate, a grounding rod fixedly connected to the interior of the base plate, a grounding head fixedly connected to the bottom of the grounding rod, a grounding wire provided on the top of the grounding rod, a protective mechanism provided on the top of the base plate, and an anti-falling mechanism provided on the top of the base plate.

[0006] Preferably, the anti-falling mechanism includes two fixed plates, both of which are fixedly connected to the top of the base plate, the interior of the two fixed plates are threadedly connected to threaded rods, the exterior of the two threaded rods are rotatably connected to bearings, the exterior of the two bearings are fixedly connected to movable plates, and the two movable plates are clamped on both sides of the grounding wire.

[0007] Preferably, the exteriors of the two movable plates are fixedly connected with compression pads, and the compression pads are made of rubber.

[0008] Preferably, a handle is fixedly connected to the outside of the threaded rod, the handle is made of stainless steel, and a plurality of arc-shaped grooves are formed on the outside of the handle.

[0009] Preferably, the bottoms of the two movable plates are fixedly connected to limiting blocks, the top of the bottom plate is provided with two corresponding limiting grooves, and the limiting blocks are slidably connected in the limiting grooves.

[0010] Preferably, the protective mechanism includes a protective cover, which is placed on the top of the base plate. Two corresponding locking shells are fixedly connected to both sides of the protective cover, and locking holes are provided inside the four locking shells. Four corresponding retaining shells are fixedly connected to the top of the base plate, and movable shafts are fixedly connected inside the four retaining shells. The outside of the movable shaft is rotatably connected to a locking plate, and the locking plate is clamped in the locking shell.

[0011] Preferably, a through hole is opened inside the locking plate, a locking bolt is inserted into the locking hole, and the locking bolt passes through the through hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. By holding the two handles and rotating them, the fixed threaded rod is driven to rotate. Since the threaded rod is threadedly connected to the fixed plate, it will move forward when rotating, and then drive the adapter bearing to start moving, and at the same time drive the external fixed movable plate to start moving to clamp the grounding wire. When the movable plate moves, the limit block fixed at the bottom slides in the limit groove, making the movement smoother. At this time, the two movable plates clamp and fix the position of the grounding wire, thereby ensuring that the grounding wire will not be disconnected from the grounding rod when it is pulled. The provided extrusion pad can ensure that the clamping is more stable, and can ensure that the outside of the connecting wire will not be squeezed and fixed and damaged. This structure effectively ensures that the grounding wire part will be disconnected from the grounding rod, making grounding and conductive work more convenient.

[0014] 2. Place the protective cover on the top of the base plate and block the outside of the grounding wire. Then rotate the four locking plates. The locking plates rotate around the movable axis and then rotate until they are locked in the lock shell. Then insert the locking bolt into the lock hole and pass through the through hole to fix the protective cover. The protective cover can effectively prevent mice from biting the grounding wire. The protective cover can be easily disassembled and assembled, making it easy to inspect and maintain the device, making it more convenient for users to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] When the grounding wire 7 is pulled away from the grounding rod 3, the grounding wire 7 is prevented from falling off by holding the two handles 604. The two handles 604 are first rotated to drive the fixed threaded rod 605 to rotate. Since the threaded rod 605 is threadedly connected to the fixed plate 601, it will move forward when rotating, and then drive the adapter bearing 606 to start moving, and at the same time drive the external fixed movable plate 602 to start moving to clamp the grounding wire 7.
