Description

Technical Field

[0001] This utility model relates to the field of surge arrester technology, and in particular to a surge arrester with a wind-resistant structure. Background Technology

[0002] A surge arrester, also known as a surge protector or overvoltage protector, is a crucial safety protection device in power systems and electronic equipment. Its core function is to limit overvoltages caused by lightning or operational actions, protecting the insulation of electrical equipment from damage.

[0003] However, in the existing technology, traditional lightning rods do not have wind-resistant mechanisms. When the wind is strong, the lightning rod is easy to tilt or even break, thereby reducing the lightning protection effect of the lightning rod on the building or power system. Moreover, most lightning rods have low stability and are easy to loosen when exposed to wind for a long time, thereby reducing the wind resistance effect and the service life of the lightning rod. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where traditional lightning rods do not have wind-resistant mechanisms, making them prone to tipping over or even breaking when the wind is strong, thus reducing the lightning protection effect of the lightning rod on buildings or power systems. Moreover, most lightning rods have low stability and are easily loosened by wind over a long period of time, thus reducing their wind resistance and service life.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a lightning arrester with a wind-resistant structure, comprising: a mounting base, wherein a lightning rod body is fixedly disposed at the center of the mounting base, and further comprising: A stabilizing component is disposed on the outer surface of the mounting base, the stabilizing component comprising: Multiple rectangular plates are fixedly mounted on the outer surface of the mounting base, and adjusting screws are movably mounted on the outer surface of the rectangular plates; A turntable is fixedly mounted on one end of the adjusting screw, and the outer surface of the turntable is provided with multiple positioning holes; Multiple grooves are formed on the outer surface of the mounting base, and guide rods are fixedly installed inside the grooves; An air guide assembly is disposed on the outer surface of the rectangular plate.

[0006] Preferably, the stabilizing component further includes: A slider is movably mounted on the outer surface of the guide rod, and an arc-shaped plate is fixedly mounted on the top of the slider; The slider can slide laterally inside the groove; An annular sleeve is fixedly installed at the center of one side of the arc-shaped plate; One end of the adjusting screw is movably positioned inside the annular sleeve.

[0007] The technical effect of adopting the above-mentioned further solution is that the rotating adjusting screw pushes the arc plate to move through the annular sleeve. Under the action of the slider, the arc plate is better stabilized, so that the arc plate fits better with the lower end of the lightning rod body. The relative movement of multiple arc plates supports the lower end of the lightning rod body, improving the connection effect between the lightning rod body and the mounting base.

[0008] Preferably, the air guide assembly includes: An annular plate is fixedly mounted on the top of the rectangular plate, and an annular groove is formed on the outer surface of the annular plate; An annular plate is movably disposed inside the annular groove, and a circular plate is fixedly disposed on the outer surface of the annular plate. Multiple air guide vanes are fixedly installed on the top of the annular plate.

[0009] The technical effect of adopting the above-mentioned further solution is that when strong wind blows onto multiple wind guide blades, the wind guide blades rotate through the circular plate and the annular clamping plate. The rotation of the wind guide blades can disperse the wind, reduce the wind force that directly blows onto the main body of the lightning rod, and reduce the contact area between the wind and the main body of the lightning rod through the wind guide blades, thereby improving the wind resistance of the main body of the lightning rod.

[0010] Preferably, the inner surface of the annular plate is movably provided with a plurality of balls, which are movably disposed inside the annular groove.

[0011] The technical effect of adopting the above-mentioned further solution is that multiple balls can improve the rotation effect of the annular plate, reduce resistance, and better improve the effect of dispersing air.

[0012] Preferably, a plurality of dampers are fixedly disposed on the inner surface of the annular plate, and the other end of the dampers is connected to the lightning rod body. The damper is installed at an angle.

[0013] The technical effect of adopting the above-mentioned further solution is that the damper is installed at an angle with the main body of the lightning rod, and the damper dissipates the vibration energy of the wind on the main body of the lightning rod and provides damping force.

[0014] Preferably, a limiting block is fixedly provided on the upper end of one side of the rectangular plate, and a fixing bolt is movably provided on the outer surface of the limiting block.

[0015] The technical effect of adopting the above-mentioned further solution is that: the fixing bolt is tightened and embedded in one of the positioning holes, which can position the turntable and thus limit the adjustment screw.

[0016] Preferably, a rubber pad is fixedly provided on one side of the arc-shaped plate.

[0017] The technical effect of adopting the above-mentioned further solution is that the rubber pad can not only improve the friction and make the arc plate fit better with the lightning rod body, but also play an insulating role to prevent lightning from damaging the stabilizing components.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the rotating adjusting screw pushes the arc plate to move through the annular sleeve. The arc plate is more stable under the action of the slider, so that the arc plate fits better with the lower end of the lightning rod body. The relative movement of multiple arc plates supports the lower end of the lightning rod body, improving the connection effect between the lightning rod body and the mounting base. After the arc plate is adjusted, the fixing bolt is embedded in the interior of one of the positioning holes. By positioning the turntable, the stability of the adjusting screw is improved, preventing the adjusting screw from loosening and affecting the support and stability of the arc plate for the lightning rod body.

[0019] 2. In this utility model, when strong wind blows onto multiple wind guide blades, the wind guide blades rotate through the annular plate and the annular retaining plate. The rotation of the wind guide blades can disperse the wind and reduce the wind force that directly blows onto the lightning rod body. The wind guide blades can reduce the contact area between the wind and the lightning rod body, thereby improving the wind resistance of the lightning rod body. The annular retaining plate is inside the annular groove, and multiple balls can reduce the friction with the annular groove, thus better driving the wind guide blades to rotate.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, such as Figure 1-4 As shown, this utility model provides a surge arrester with a wind-resistant structure, including: a mounting base 1, a stabilizing component, and a wind-guiding component; The stabilizing components include: a lightning rod body 102 fixedly installed at the top center of the mounting base 1; multiple rectangular plates 101 fixedly installed on the outer surface of the mounting base 1; the multiple rectangular plates 101 are installed in a circular array around the lightning rod body 102; and an adjusting screw 117 is threaded onto the outer surface of the rectangular plates 101. Multiple grooves 109 are provided on the outer surface of the mounting base 1. A guide rod 110 is fixedly embedded inside the groove 109. A slider 111 is movably sleeved on the outer surface of the guide rod 110. An arc plate 118 is fixedly installed on the top of the slider 111. An annular sleeve 119 is fixedly installed at the center of one side of the arc plate 118. The slider 111 can improve the stability of the arc plate 118 through the guide rod 110, making it more stable to move and adjust. One end of the adjusting screw 117 is movably embedded inside the annular sleeve 119. When the adjusting screw 117 is adjusted, it drives the arc plate 118 to move through the annular sleeve 119, so that the arc plate 118 contacts the lower end of the lightning rod body 102. A rubber pad 120 is fixedly installed on the outer surface of the arc plate 118. The rubber pad 120 can not only improve the friction and make the arc plate 118 fit better with the lightning rod body 102, but also play an insulating role to prevent lightning from damaging the stabilizing components.

[0025] In this embodiment, a turntable 105 is fixedly installed at one end of the adjusting screw 117. The outer surface of the turntable 105 is provided with a plurality of positioning holes 106. A limit block 107 is fixedly installed at the upper end of one side of the rectangular plate 101. A fixing bolt 108 is threaded on the outer surface of the limit block 107. The fixing bolt 108 is tightened and embedded into the interior of one of the positioning holes 106, which can position the turntable 105, thereby limiting the adjusting screw 117 and preventing the adjusting screw 117 from reducing the stabilizing effect on the arc plate 118.

[0026] Example 2, as Figure 1-4 As shown, the air guiding assembly includes: an annular plate 112 fixedly installed on the top of the rectangular plate 101; an annular groove 116 is opened on the outer surface of the annular plate 112; an annular retaining plate 113 is movably embedded in the annular groove 116; and a plurality of balls 114 are rotatably installed on the inner surface of the annular retaining plate 113, with the balls 114 movably embedded in the annular groove 116. A circular ring plate 103 is fixedly installed on the outer surface of the annular plate 113, and multiple air guide blades 104 are fixedly installed on the top of the circular ring plate 103. When multiple wind guide blades 104 are blown by strong wind, they drive the annular plate 113 to rotate inside the annular groove 116 through the annular plate 103. The wind guide blades 104 also disperse the wind, reduce the wind speed, and reduce the contact between the wind and the lightning rod body 102. Multiple ball bearings 114 can improve the rotation effect of the annular plate 113, reduce resistance, and better improve the wind dispersion effect.

[0027] In this embodiment, multiple dampers 115 are fixedly installed on the inner surface of the annular plate 112. The other end of the damper 115 is connected to the lightning rod body 102. The damper 115 is installed at an angle and has a certain angle with the lightning rod body 102. The damper 115 dissipates the vibration energy of the wind on the lightning rod body 102 and provides damping force.

[0028] Working principle: Rotating the adjusting screw 117 pushes the arc plate 118 to move through the annular sleeve 119. Under the action of the slider 111, the arc plate 118 is better stabilized, making the arc plate 118 fit better with the lower end of the lightning rod body 102. The relative movement of multiple arc plates 118 supports the lower end of the lightning rod body 102, improving the connection effect between the lightning rod body 102 and the mounting base 1. After the arc plate 118 is adjusted, the fixing bolt 108 is embedded in one of the positioning holes 106. By positioning the turntable 105, the stability effect of the adjusting screw 117 is improved, preventing the adjusting screw 117 from loosening and affecting the support and stability effect of the arc plate 118 on the lightning rod body 102. When strong winds blow onto the multiple guide vanes 104, the guide vanes 104 rotate via the annular plate 103 and the annular retaining plate 113. The rotation of the guide vanes 104 disperses the wind, reducing the wind force that blows directly onto the lightning rod body 102. The guide vanes 104 reduce the contact area between the wind and the lightning rod body 102, thereby improving the wind resistance of the lightning rod body 102. The annular retaining plate 113 is inside the annular groove 116, and multiple balls 114 reduce the friction with the annular groove 116, thus better driving the guide vanes 104 to rotate.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
