Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection, in particular to a lightning protection structure for a building project. Background Art

[0002] Construction projects refer to the engineering entities formed by the construction of various buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Lightning protection for construction projects is a commonly used technical means in construction projects. Usually, a lightning rod is installed on the top of the building, and a lightning conductor is installed at the bottom of the lightning rod, which extends to the ground. However, the traditional lightning protection structure has the following shortcomings when used:

[0003] 1. Due to their height, many lightning rods are shaken by wind for a long time, which can easily lead to structural looseness and shorten the maintenance cycle.

[0004] Therefore, we propose a lightning protection structure for building engineering. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art that many lightning rods shake due to their height and are affected by wind for a long time, which easily leads to structural looseness and shortens the maintenance cycle, and proposes a lightning protection structure for construction projects.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A lightning protection structure for a building project, comprising:

[0008] A base, wherein a fixed tube is fixedly arranged on the surface of the base, a lifting rod is slidably connected to the inner wall of the fixed tube, a lightning rod body is threadedly connected to the top of the lifting rod, a screw is rotatably connected to the inner wall of the bottom of the base, and the screw and the lifting rod are threadedly connected;

[0009] Two positioning rings, both of which are fixed on the outer wall of the fixed pipe, and a guide shell is rotatably connected between the two positioning rings;

[0010] The adjusting mechanism is arranged on the outer wall of the fixed tube and is used for adjusting the screw rod.

[0011] In a possible design, the adjustment mechanism includes a first gear, a through groove and an adjustment ring. The first gear is fixed to the outer wall of the screw. The through groove penetrates the outer wall of the fixed tube. A second gear is rotatably connected in the through groove. The first gear and the second gear are meshed with each other. The adjustment ring is rotatably connected to the outer wall of the fixed tube. The circumferential inner wall of the adjustment ring is integrally formed with a plurality of teeth, which are meshed with the second gear.

[0012] In a possible design, the guide shell includes two half shells and a plurality of connecting blocks. The half shells and the connecting blocks are fixedly connected by screws. The inner walls of the two half shells are fixed with positioning blocks that match the positioning rings.

[0013] In a possible design, the inner walls of the two positioning blocks are each provided with a plurality of spherical grooves, balls are each provided in the plurality of spherical grooves, and the outer walls of the two positioning rings are each provided with an annular groove matched with the balls.

[0014] In a possible design, a plurality of anti-sliding blocks are provided on the surface and the bottom of the adjusting ring.

[0015] In a possible design, a reinforcement bracket is provided on the outer wall of the fixed tube.

[0016] In the present application, when the lightning rod body is stored, the adjusting ring is rotated, the adjusting ring drives the teeth to rotate and then drives the second gear to rotate, the second gear drives the first gear to rotate, the first gear drives the screw to rotate, the screw drives the lifting rod to rise and fall, and the lifting rod drives the lightning rod body to be stored into the fixed tube;

[0017] Under the influence of natural wind, the guide shell automatically rotates to face the direction of the natural wind, thereby diverting and guiding the natural wind. The front and rear ends of the guide shell have a smaller curvature than the outer wall of the fixed pipe, which can reduce the pressure on the fixed pipe and thus reduce the pressure on the lightning protection structure.

[0018] In the utility model, the lightning protection structure for building engineering, through the arrangement of multiple structures such as screw rods, lifting rods and guide shells, can store the lightning rod in the fixed tube in the season with less thunderstorms, thereby reducing the pressure on the lightning protection structure under natural wind. At the same time, the guide shell can guide the natural wind, thereby reducing the pressure on the lightning protection structure under natural wind, avoiding structural loosening, and thus extending the maintenance cycle.

[0019] In the utility model, the lightning protection structure for building engineering can reduce the resistance of the guide shell when it rotates by setting the ball and the annular groove, so as to facilitate the guide shell to rotate under the blowing of natural wind, thereby guiding the natural wind;

[0020] In the utility model, the pressure on the lightning protection structure under natural wind can be reduced, the loosening of the structure can be avoided, and the maintenance cycle can be extended. The resistance encountered by the guide shell when rotating can also be reduced, which makes it easier to guide the natural wind. BRIEF DESCRIPTION OF THE DRAWINGS
