Description

Technical Field

[0001] The utility model relates to the technical field of lightning rods, and in particular to a replaceable lightning protection device for a communication base station. Background Art

[0002] The replaceable lightning protection device for communication base stations is an important device used to protect base station equipment from lightning damage. It can effectively disperse the energy of lightning strikes and direct it to the ground, thereby protecting base station equipment from damage by lightning strikes. At the same time, it adopts a replaceable design, so that when the lightning protection device is damaged or fails, it can be easily replaced, thereby ensuring the continuous and stable operation of the base station.

[0003] After searching, the Chinese patent application No. 201620931616.5 discloses a high-performance lightning protection and grounding communication tower lightning rod, including a tower body, a lightning collector, a lightning grounding rod and an underground electric disperser. The uppermost end of the tower body is provided with a lightning collector, and is fixedly connected by a lightning rod connecting flange. A vertical lightning guide needle is provided at the upper end of the lightning collector, and a plurality of oblique lightning guide needles are arranged around the side of the vertical lightning guide needle. The lower end of the oblique lightning guide needle is welded and fixed to the side of the lightning collector. A lightning grounding rod is provided at the lower end of the lightning collector. The utility model can prevent lightning from striking the communication tower, can quickly transmit lightning to the ground, and quickly disperse lightning, so as to minimize the damage of lightning to the communication tower and the influence of communication, and effectively protect the tower body. The device can also ground the high voltage in the tower body, and can also protect the equipment in normal times. It has multiple functions, high anti-electricity efficiency and high safety performance.

[0004] Although the above patent can achieve a certain lightning protection effect when used, it still has the following shortcomings: it is not convenient for transportation and handling. There are usually multiple sets of side rods fixed on the surface of the lightning rod to attract lightning. However, since communication base stations are usually installed on the top of iron towers or high-rise buildings, the lightning rod needs to be hoisted and transported. The side rod design on its surface may stab the hands of the transporters, causing the lightning rod to slide or tilt during transportation, increasing the difficulty and risk of transportation.

[0005] Therefore, a replaceable lightning protection device for communication base stations is urgently needed to solve the above problems. Utility Model Content

The screw rod 303 is driven to rotate by rotating the swivel 302, so that the movable seat 306 is lifted and lowered on the surface of the screw rod 303 through the engagement of the thread. At the same time, the movable seat 306 drives the first side rod 2 to move through the sleeve 304. When the movable seat 306 rises, the sleeve 304 pushes the first side rod 2 to move upward, and at the same time, the transmission rod 301 pushes the first side rod 2 to flip outward to unfold the first side rod 2. When the movable seat 306 descends, the sleeve 304 pushes the first side rod 2 to move downward, and at the same time, the transmission rod 301 pulls the first side rod 2 close to the rod body 1 to close the first side rod 2.

By pulling the rod body 1 on the inner rod 601, the sliding structure is formed. The outer side of the rod 1 is slid to adjust the height of the rod body 1, and then the fixing rod 605 is rotated to move the fixing rod 605 downward along the thread inside the screw sleeve 604. Then the fixing rod 605 contacts and rubs with the friction pad 603 to fix the position between the rod body 1 and the inner rod 601.

When the movable seat 306 rises, the casing 304 pushes the first side rod 2 to move upward, and the transmission rod 301 pushes the first side rod 2 to flip outward to unfold the first side rod 2. When the movable seat 306 descends, the casing 304 pushes the first side rod 2 to move downward, and the transmission rod 301 pulls the first side rod 2 close to the rod body 1 to close the first side rod 2.

[0037] Specifically, when the replaceable lightning protection device for the communication base station is in use: by pulling the rod body 1 to slide on the outside of the inner rod 601, the height of the rod body 1 is adjusted, and then the fixed rod 605 is rotated to make the fixed rod 605 move downward along the thread inside the screw sleeve 604, and then the fixed rod 605 contacts and rubs with the friction pad 603 to fix the position between the rod body 1 and the inner rod 601, and the sliding rail 602 is used to limit the movement path of the inner rod 601, so that the friction pad 603 is aligned with the fixed rod 605, and the friction force between the fixed rod 605 and the inner rod 601 is increased by the friction pad 603, so as to facilitate fixing the position between the inner rod 601 and the rod body 1.
