Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection devices, in particular to a spherical lightning receptor. Background Art

[0002] The lightning receptor releases static charge through its tip, guiding the lightning current along the needle rod of the lightning receptor to flow into the earth, so that the protected object is prevented from being struck by lightning. The spherical lightning receptor can effectively attract and guide lightning. However, the needle tip of the lightning receptor is easily deformed and damaged when struck by lightning, which affects the operation of the lightning receptor. It is difficult and costly to replace the lightning receptor. Summary of the Invention

[0003] In order to solve the above technical problems, the utility model provides a spherical lightning receptor, which only requires the replacement of the needle tip, reducing the difficulty and cost.

[0004] The technical solution is as follows: a spherical lightning rod, which includes a fixed base, a spherical body and a needle tip, characterized in that a plug-in tube is provided on the top of the spherical body, an internal thread is provided in the opening of the plug-in tube, a matching external thread is provided at the bottom of the needle tip and is threadedly connected to the plug-in tube, a lightning rod is provided at the bottom of the spherical body, and the lightning rod is connected to the fixed base.

[0005] It is further characterized in that a double-ear plate is provided on the top of the fixed base, and a single-ear plate is provided on the bottom of the lightning receptor needle rod, and the single-ear plate is inserted into the double-ear plate and locked by bolts and nuts to achieve the connection between the lightning receptor needle rod and the fixed base;

[0006] Reinforcement ribs are provided on the fixed base.

[0007] After adopting the utility model, when the lightning receptor is struck by lightning and the needle tip is damaged, the needle tip can be directly screwed off and replaced with a new one without replacing the entire lightning receptor, thereby reducing difficulty and cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is a schematic structural diagram of the utility model.

[0009] In the figure, 1 is the fixed base; 2 is the needle rod of the lightning receptor; 3 is the reinforcing rib; 4 is the spherical body; 5 is the needle tip; 6 is the double-ear plate; 7 is the single-ear plate. DETAILED DESCRIPTION

[0010] See Figure 1As shown, a spherical lightning receptor comprises a fixed base 1, a spherical body 4 and a needle tip 5. A plug-in tube is provided on the top of the spherical body 4, and an internal thread is provided in the opening of the plug-in tube. The bottom of the needle tip 5 is provided with a matching external thread and is threadedly connected to the plug-in tube. When installing, the threads can be directly tightened. A lightning receptor needle rod 2 is provided at the bottom of the spherical body 4, and the lightning receptor needle rod 2 is connected to the fixed base 1.

[0011] A double-ear plate 6 is provided on the top of the fixed base 1, and a single-ear plate 7 is provided on the bottom of the lightning receptor needle rod 2. Anti-slip patterns are provided on the surface to enhance contact friction. The single-ear plate 7 is inserted into the double-ear plate 6 and is locked by bolts and nuts to realize the connection between the lightning receptor needle rod 2 and the fixed base 1. When the direction of the needle tip 5 needs to be adjusted, slightly loosen the bolts and nuts, and rotate the lightning receptor needle rod 2 with the bolt as the center to point the needle tip in the required direction.

[0012] The fixed base 1 is made of metal material, which can be stainless steel or hot-dip galvanized steel plate. The shape can be designed according to the actual application scenario, such as round, square or other shapes. Reinforcement ribs 3 are provided to improve the reliability of the base.

[0013] The spherical body 4 and the needle tip 5 are also made of stainless steel or hot-dip galvanized steel sheet.

[0014] The needle tip replacement operation in this application is simple, and only needs to be screwed and replaced, without the need for professional personnel, which reduces maintenance costs. It can also adjust the installation angle of the lightning rod, and has a wider range of applications.
