[0031] like Figure 1-3 The antistatic device shown comprises a pair of symmetrical contact bodies 1, an electrostatic body 2, two conductive posts 3 arranged on the electrostatic body 2, two opposite adjustment rods 4, a grounding connection line 5 and a tower connection block 6 for clamping to an iron tower.
[0032] The contact body 1 is used to contact an electrostatic body that generates static electricity.
[0033] For commonly used wires, such as Figure 2-3 The pair of contact bodies 1 shown is a pair of hooks, symmetrically arranged at the top of the electrostatic body 2, and used to hang on the wires and electric wires. The contact body 1 is a hook with an opening downward, and the pair of contact bodies 1 can be hung on the wires. The contact body 1 can be made of metal strips or metal wires.
[0034] For common hardware, such as Figure 1 The contact body 1 shown is an S-shaped metal strip with two arc sections, and the two contact bodies 1 are symmetrically arranged at the top of the electrostatic body 2. The arc section above the contact body 1 forms an opening, and the arc section below it forms a ring. The hardware enters the ring from the opening, and the ring is used to surround the hardware with static electricity. The two contact bodies 1 are elastic and can be stuck on the outer surface of the cylindrical metal.
[0035] The electrostatic body 2 is Y-shaped as a whole, preferably an insulating flat plate. It includes a V-shaped upper connector 21 and two strip-shaped lower connectors 22; the upper connector 21 is fastened with two bolts arranged at intervals by threaded connection, and the metal wire located at the root of the contact body 1 is wound around the corresponding bolts and then electrically connected to the conductive column 3. The two bolts are respectively located on the left and right sides of the upper connector 21, and the conductive column 3 is also located on the left and right sides of the upper connector 21, and the two bolts are located above the conductive column 3. Each contact body on the left and right sides is respectively connected in series with the bolts and conductive columns on the same side of the contact body. The root, i.e., the bottom end of the upper connector 21 is located in the middle of the top ends of the two lower connectors 22, and the fasteners fasten the upper connector 21 and the two lower connectors 22 together. The contact body 1 is connected to the two tips of the upper connector 21.
[0036] Two conductive columns 3 are vertically mounted on the electrostatic body 2, and the root of the contact body 1 is electrically connected to the corresponding conductive columns 3. One end of the grounding connection line 5 is connected to any conductive column 3, and the other end is connected to the tower connection block 6. A position-variable adjustment rod 4 is connected to each conductive column 3. When the two adjustment rods 4 are in contact, the contact body 1 of the electrostatic contact can be electrically connected to the iron tower. The axial direction of the adjustment rod 4 is parallel to the electrostatic body 2.
[0037] Specifically, the adjusting rod 4 is threadedly sleeved inside the conductive column 3 to form a single screw pair, and the adjacent ends of the two adjusting rods 4 are spheres. The two adjusting rods 4 can preferably move closer to or farther from each other at the same time. In this way, one end of the grounding connection line 5 is connected to any conductive column 3, so that the two contact bodies 1 and the conductive column 3 can be merged to one end of the grounding connection line 5.
[0038] More specifically, the conductive column 3 includes a thick column cap and a thin mounting screw, and the mounting screw is threadedly connected to the electrostatic body 2. In this way, the conductive column 3 is simply and firmly mounted on the electrostatic body 2. Two conductive columns 3 are respectively mounted on the upper connector 21.
[0039] There is a gap between the column cap and the electrostatic body 2, and the metal wire connected to the root of the contact body 1 can be wound around the mounting screw located between the column cap and the electrostatic body 2. The function of the metal wire is to electrically connect the contact body 1 and the conductive column 3. The column cap has the function of pressing the metal wire. Preferably, the ground connection line 5 and the column cap are distributed on both sides of the electrostatic body 2, such as Figure 1 The back side of the electrostatic body 2 is shown. The ground connection line 5 is located on the back side of the electrostatic body 2 , and the column cap is located on the front side of the electrostatic body 2 .
[0040] More preferably, two bolts arranged at intervals are fastened on the upper connector 21 by threaded connection, and the metal wire at the root of the contact body 1 can be wound around the bolts and then wound around the mounting screw. The two bolts arranged at intervals are located above the conductive column 3.
[0041] Preferably, the tower connection block 6 includes a connection block body 61 with an opening on one side, a clamping plate 62 placed in the opening, a screw 63 is fixed to the top surface of the clamping plate 62, and the connection block body 61 is connected to the ground connection line 5. The connection block body 61 is a horizontal U-shaped frame structure as a whole. The screw 63 is threadedly connected to the connection block body 61, and the distance between the clamping plate 62 and the bottom surface of the opening can be adjusted by adjusting the position of the screw 63 relative to the connection block body 61. The screw 63 passes through the upper side wall of the connection block body 61, and the distance between the lower side wall of the connection block body 61 and the clamping plate 62 is adjustable, which is used to clamp on both sides of the steel sheet of the iron tower. The structure of the tower connection block 6 can refer to the wire clamp structure of the insulating rod.
[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
