Description

Technical Field

[0001] The utility model relates to the field of lightning arresters, and particularly relates to a post-type lightning arrester. Background Art

[0002] A post-type lightning arrester is a component used to protect various electrical equipment in a power system from damage caused by lightning overvoltage, switching overvoltage, and voltage surges. It is applicable to overvoltage protection of transformers, transmission lines, switch cabinets, power metering boxes, rotating electrodes, semiconductor devices, etc. It can protect the power system from instantaneous overvoltage hazards and can intercept and interrupt the follow current to avoid system ground short circuits.

[0003] The post-type lightning arrester mainly consists of a sheath, a flip cover, a lightning arrester body, a mounting bracket, and a disconnector. The flip cover is used to protect the extension rod on the lightning arrester. When the flip cover is not in use, it is stuck on the surface of the extension rod. However, the flip cover can only wrap a part of the extension rod, and the other part of the extension rod is exposed. And after the flip cover is stuck on the surface of the extension rod, due to the absence of a locking structure, the flip cover is prone to accidentally flip open. Before the lightning arrester is installed, a conductive band is installed at its lower end, and the conductive band passes through the through hole of the mounting bracket. However, when carrying the lightning arrester, the conductive band will fall out of the through hole of the mounting bracket. At this time, the conductive band is in a sagging state, which is likely to damage one end of the conductive band. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a post-type lightning arrester, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A post-type lightning arrester, comprising a lightning arrester body, a sheath, and a mounting bracket. A sheath is provided at the upper end of the lightning arrester body. An extension rod is fixedly installed on one side of the upper end of the lightning arrester body. A flip cover is movably installed at the upper end of the extension rod. A mounting bracket is fixedly sleeved on the surface of the lightning arrester body near the lower end. A clamping member is movably installed inside the front end of the mounting bracket.

[0007] Preferably, a clamping groove is formed on the surface of one end of the flip cover. A rotating block is movably installed on the surface of one end of the flip cover. A clamping block is fixedly installed on the rear surface of the rotating block. A semi-circular plate is fixedly installed on the rear surface of the rotating block.

[0008] Preferably, the clamping block is embedded in the clamping groove. The rotating block is movably connected to the flip cover through the clamping block. The rear end of the semi-circular plate extends into the flip cover. The outer diameter of the semi-circular plate is smaller than the inner diameter of the flip cover.

[0009] Preferably, a threaded hole is formed on the front end face of the mounting bracket, a through hole is formed on the upper surface of the front end of the mounting bracket, limiting sliding grooves are formed on the upper surfaces on both sides of the through hole, and the threaded hole communicates with the through hole.

[0010] Preferably, the clamping member includes a knob, a threaded rod, a clamping plate, a cross plate and a limiting slider. A threaded rod is fixedly installed on the rear surface of the knob, and the rear end of the threaded rod passes through the threaded hole and extends into the through hole.

[0011] Preferably, a clamping plate is movably installed on the rear end face of the threaded rod, a cross plate is fixedly installed on the upper surface of the clamping plate, and limiting sliders are fixedly installed on the lower surfaces at both ends of the cross plate.

[0012] Preferably, the limiting slider is embedded in the limiting sliding groove, the rotating block is semicircular, and the extension rod passes through the sheath and is fixed to the arrester body.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, by means of the mutual cooperation of the flip cover, the mounting bracket and the clamping member, after the flip cover is stuck on the surface of the extension rod, the semicircular plate is rotated by using the rotating block. When the semicircular plate is turned 180°, the extension rod can be completely wrapped, which can not only effectively protect the extension rod, but also prevent the flip cover from being accidentally flipped open. When one end of the conductive band passes through the through hole of the mounting bracket and is placed, the knob of the clamping member is rotated. The rotating knob drives the threaded rod and the clamping plate to continuously approach the conductive band in the through hole until the conductive band is clamped in the through hole by the clamping plate, thus preventing the conductive band from falling out of the through hole.

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, a pillar-type lightning arrester includes a lightning arrester main body 2, a sheath 1 and a mounting bracket 5. A sheath 1 is provided at the upper end of the lightning arrester main body 2. An extension rod 3 is fixedly installed on one side of the upper end of the lightning arrester main body 2. A flipping cover 4 is movably installed at the upper end of the extension rod 3. A mounting bracket 5 is fixedly sleeved on the surface of the lightning arrester main body 2 near the lower end. A clamping piece 6 is movably installed inside the front end of the mounting bracket 5.

[0022] A card slot 401 is opened on the surface of one end of the flipping cover 4. A rotating block 402 is movably installed on the surface of one end of the flipping cover 4. A clamping block 403 is fixedly installed on the rear surface of the rotating block 402. A semi-circular plate 404 is fixedly installed on the rear surface of the rotating block 402. There is a certain frictional force between the clamping block 403 and the card slot 401; the clamping block 403 is embedded in the card slot 401, and the rotating block 402 is movably connected to the flipping cover 4 through the clamping block 403. The rear end of the semi-circular plate 404 extends into the flipping cover 4, and the outer diameter of the semi-circular plate 404 is smaller than the inner diameter of the flipping cover 4; a threaded hole is opened on the front end face of the mounting bracket 5, a through hole 501 is opened on the upper surface of the front end of the mounting bracket 5, and limit sliding grooves 502 are opened on the upper surfaces on both sides of the through hole 501. The threaded hole communicates with the through hole 501. The cooperation between the limit sliding grooves 502 and the limit sliding blocks 605 can assist the clamping plate 603 to move smoothly; the clamping piece 6 includes a knob 601, a threaded rod 602, a clamping plate 603, a cross plate 604 and limit sliding blocks 605. A threaded rod 602 is fixedly installed on the rear surface of the knob 601. The rear end of the threaded rod 602 passes through the threaded hole and extends into the through hole 501; a clamping plate 603 is movably installed on the rear end face of the threaded rod 602. A cross plate 604 is fixedly installed on the upper surface of the clamping plate 603. Limit sliding blocks 605 are fixedly installed on the lower surfaces at both ends of the cross plate 604; the limit sliding blocks 605 are embedded in the limit sliding grooves 502. The rotating block 402 is semi-circular, and the extension rod 3 passes through the sheath 1 and is fixed to the lightning arrester main body 2.

[0023] It should be noted that the present utility model is a pillar-type lightning arrester. When in use, after the flipping cover 4 is stuck on the surface of the extension rod 3, the semi-circular plate 404 is rotated by the rotating block 402. When the semi-circular plate 404 is flipped 180°, the extension rod 3 can be completely wrapped, which not only effectively protects the extension rod 3, but also prevents the flipping cover 4 from accidentally flipping open. When one end of the conductive band is placed through the through hole 501 of the mounting bracket 5, the knob 601 of the rotating clamping member 6 is rotated. The rotating knob 601 drives the threaded rod 602 and the clamping plate 603 to continuously approach the conductive band in the through hole 501 until the conductive band is clamped in the through hole 501 by the clamping plate 603, thus preventing the conductive band from falling out of the through hole 501.
