Description

Technical Field

[0001] The utility model relates to the field of lightning arresters, and particularly to an earthquake-resistant lightning arrester. Background Technique

[0002] The lightning arrester is connected between the cable and the ground and is usually connected in parallel with the protected equipment. The lightning arrester can effectively protect communication equipment. Once an abnormal voltage appears, the lightning arrester will act and play a protective role. When the communication cable or equipment operates under the normal working voltage, the lightning arrester will not work and is regarded as an open circuit to the ground. Once a high voltage appears and endangers the insulation of the protected equipment, the lightning arrester will immediately act and direct the high-voltage impulse current to the ground, thereby limiting the voltage amplitude and protecting the insulation of the communication cable and equipment. After the overvoltage disappears, the lightning arrester quickly returns to its original state and enables the communication line to work normally.

[0003] For the existing earthquake-resistant lightning arresters, during installation, most lightning arresters are directly fixed at the corresponding positions through multiple groups of bolts. When encountering strong convective weather such as strong winds, the longer lightning arresters are prone to problems such as large overall left-right shaking amplitude of the lightning arrester, which is likely to cause damage to the lightning arrester. Therefore, an earthquake-resistant lightning arrester is needed to assist in solving this problem. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an earthquake-resistant lightning arrester to solve the technical problem that for the existing earthquake-resistant lightning arresters, during installation, most lightning arresters are directly fixed at the corresponding positions through multiple groups of bolts. When encountering strong convective weather such as strong winds, the longer lightning arresters are prone to large overall left-right shaking amplitude of the lightning arrester, which is likely to cause damage to the lightning arrester.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An earthquake-resistant lightning arrester includes a base plate. The base plate has an L-shaped plate structure. A hinge seat is fixed at the top of the base plate. Sliding grooves are symmetrically opened at the top of the base plate. An installation component is installed in the sliding grooves. A lightning arrester body is installed at the installation component. A clamping ring is sleeved and installed on the lightning arrester body. A tensioning bracket is inclined and hinged between the hinge seat and the clamping ring;

[0006] The installation component includes a sliding block. The sliding block is slidably and clamped in the sliding groove. A threaded rod is vertically fixed at the top of the sliding block. A through hole for the threaded rod to pass through is opened on the installation disk at the bottom of the lightning arrester body. A nut is threadedly installed on the threaded rod.

[0007] The utility model is further provided that an anti-slip pad is embedded and installed at the outer edge of the sliding block. The vertical cross-section of the sliding block is in a middle shape. One end of the sliding block protrudes with a protruding block.

[0008] The present invention is further configured such that a scale plate is embedded in the base plate corresponding to the sliding groove, and length scale lines are engraved on the scale plate.

[0009] The present invention is further configured such that the snap-fit ​​ring includes a first mounting ring and a second mounting ring, both ends of the first mounting ring and the second mounting ring are provided with fixing ears, and the tensioning bracket is connected and fixed to the fixing ears by a fixing component.

[0010] The present invention is further configured such that the fixing component includes a sleeve and a lead screw, the sleeve and the lead screw are threaded together, and a protruding disc is fixed at one end of the sleeve and the lead screw that are far apart from each other, and a fixing ring is fixed on the outer side of the protruding disc.

[0011] The present invention is further configured such that the tensioning bracket includes a fixed cylinder, the fixed cylinder has a cavity inside, a connecting rod is slidably disposed in the cavity, a fixed seat is fixed to one end of the connecting rod extending out of the fixed cylinder, and a top pressure spring for assisting the connecting rod to push is installed in the cavity.

[0012] The present invention is further configured such that a plurality of through holes are symmetrically formed on the base plate, and the through holes penetrate the base plate.

[0013] In summary, the present invention has the following advantages: the present invention, through the cooperation between the fixing ring installed on the arrester body and the inclined tensioning bracket, can effectively support the long arrester body during operation, and can minimize the risk of damage to the arrester in strong convective weather such as strong winds by providing auxiliary support.

[0014] By utilizing the sliding groove and the cooperation between the mounting components within it, the sliding block is pushed, which in turn moves the threaded rod to the designated position. The threaded rod is then adjusted to the designated position according to the through hole on the mounting plate at the bottom of the surge arrester body, and the positioning pin at the bottom of the mounting plate is inserted into the positioning hole. The initial positioning and fastening of the surge arrester body is completed through the threaded engagement between the nut and the threaded rod. This method can adapt to the overall installation requirements of surge arrester bodies of different sizes during installation, improving the overall ease of installation.
