Description

Technical Field

[0001] The invention belongs to the technical field of cable installation, and in particular relates to a windproof lightning arrester and an installation method thereof. Background Art

[0002] Cable lightning arrester is a cable installation protection device, mainly used to prevent lightning and other overvoltage events from damaging the cable system. Its basic function is to guide the excessive voltage to the ground when lightning or other transient overvoltage occurs, thereby protecting the connected equipment from damage.

[0003] The Chinese patent with application number 202321853994.2 discloses a lightning arrester base and a high-voltage lightning arrester, including a connecting seat, the connecting seat includes a mounting plate, a fixed fork is fixedly provided on the upper end of the mounting plate, two limit blocks are symmetrically provided on both sides of the fixed fork, a mounting block is fixedly provided on the end of the limit block away from the fixed fork, a movable fork is slidably provided between the two limit blocks, an adjusting screw is threadedly installed on the mounting block, one end of the adjusting screw is rotatably installed on the movable fork, the lower end of the connecting seat is connected to the adjusting mechanism, the adjusting mechanism is used to adjust the direction and length of the lightning arrester base, and the lower end is connected to the mounting seat. The patent can adjust the position of the movable fork by adjusting the screw, so that the movable fork cooperates with the fixed fork to quickly fix the high-voltage lightning arrester, is not easy to loosen and is easy to disassemble and assemble. The patent can adjust the height and installation angle of the lightning arrester base and can be applied to different use environments.

[0004] During the installation of the lightning arrester, the lightning arrester is usually installed on the bracket by bolts. However, this rigid connection will cause the bracket to vibrate when encountering strong winds or other extreme environments. At this time, the lightning arrester will be affected by the vibration and may be damaged. At the same time, the structure of the lightning arrester is easily unstable in strong winds. In order to avoid being affected by strong winds, the general solution is to use a wind shield to protect it from wind. However, the wind shield will affect the heat dissipation, resulting in the lightning arrester being unable to dissipate heat in time during the overvoltage protection process and facing the risk of damage. Summary of the invention

[0005] In order to solve the deficiencies in the prior art, the present invention provides a windproof lightning arrester. The present invention can limit and fix the lightning arrester body so that the installation box can block strong winds. When the bracket vibrates due to strong winds, the influence of the bracket and the installation box on the lightning arrester body can be weakened, thereby reducing the probability of the lightning arrester body being damaged by vibration. The present invention can not only improve the installation firmness of the installation box, but also does not affect the limit fixation of the lightning arrester body and the subsequent line connection.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention achieves a non-rigid connection between the arrester body and the bracket by movably plugging the bracket and the arrester body and then limiting the bracket by a limiting mechanism. In this way, the arrester body can be limited and fixed so that the installation box can block strong winds, and the influence of the bracket and the installation box on the arrester body can be weakened when the bracket vibrates due to strong winds. Specifically, the arrester body can be well limited and fixed by the elastic limiting ring wrapped around the outer periphery of the upper and lower ends of the arrester body and the corresponding side walls of the top limiting hole and the bottom limiting hole. At this time, the installation box can block strong winds and protect the arrester body. At the same time, during the vibration of the bracket and the installation box, the force acts on the elastic limiting ring. Under the buffering effect of the elastic limiting ring, the vibration of the arrester body can be weakened, thereby reducing the probability of the arrester body being damaged by vibration.

[0022] (2) The present invention can improve the installation firmness of the installation box by forming a plug-in slot with the bottom of the installation box through the structural design of the L-shaped fixing plate of the installation box and the bottom of the installation box, while not affecting the limit fixation of the lightning arrester body and the subsequent line connection; specifically, when installation is required, since the lightning arrester body and the installation box are movably abutted, at this time, the lightning arrester body is pulled to the upper part of the interior of the installation box so that the terminal head at the lower end of the lightning arrester body can be extended into the bottom limit hole, so that the plug-in slot formed by the L-shaped fixing plate and the bottom of the installation box can be quickly plugged into the bracket; after the plug-in is completed, loosen Open the arrester body, make the elastic limiting ring at the lower end of the arrester body pass through the bottom limiting hole and the wiring hole in turn, and finally fix the installation box on the bracket by tightening the fixing screw; the installation firmness of the installation box is improved by the joint action of the elastic limiting ring at the lower end of the arrester body, the plug-in limiting of the L-shaped fixing plate and the fixing screw, so that even if the fixing screw becomes loose, the installation box and the arrester can still be temporarily limited and fixed due to the limiting of the elastic limiting ring and the plug-in limiting of the L-shaped fixing plate, and the subsequent line connection of the arrester body is not affected.

[0023] (3) The present invention adopts the structural design of the windproof mechanism, which can not only have heat dissipation in the absence of wind, but also can ensure a certain heat dissipation while preventing wind in strong winds, thereby ensuring the normal operation of the lightning arrester; specifically, when there is no wind, the first ventilation hole and the corresponding second ventilation hole are connected, thereby ensuring the heat dissipation of the left and right ends, and the space between the wind shield and the corresponding ventilation slot is open, thereby ensuring the heat dissipation of the front and rear ends; when there is strong wind, the strong wind acts on the wind shield, so that the wind shield and the corresponding adjacent ventilation slots are closed, and at the same time, the first ventilation hole and the corresponding second ventilation hole are staggered to prevent wind, and the opening between the wind shield on the opposite side and the corresponding second ventilation hole becomes larger, thereby ensuring the heat dissipation and allowing the lightning arrester to operate normally.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments. Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0035] Although the steps in the present invention are arranged with numbers, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used in this article involves and covers any and all possible combinations of one or more of the associated listed items. Example

[0036] like Figure 1 to Figure 8 As shown, a windproof lightning arrester includes a lightning arrester body 700 and a bracket 200, wherein the bracket 200 is evenly penetrated with a plurality of wiring holes 210, and the lightning arrester body 700 is movably plugged into the wiring holes 210; the terminal post 740 at the lower end of the lightning arrester body 700 passes through the corresponding wiring hole 210, and the end of the terminal post 740 at the lower end of each lightning arrester body 700 is connected in series through a connecting line 300; one end of the connecting line 300 is connected to the grounding electrode through a grounding flat iron; the cable is connected to the terminal post 740 at the upper end of the corresponding lightning arrester body 700 through a cable power line 400; the left and right ends of the bracket 200 are fixedly connected to the electric pole; a plurality of limiting mechanisms are installed on the bracket 200, and the lightning arrester body 700 is limited in the corresponding limiting mechanism.

[0037] The present invention achieves a non-rigid connection between the arrester body 700 and the bracket 200 by movably plugging the bracket 200 and the arrester body 700, which is then limited by a limiting mechanism. This can not only limit and fix the arrester body 700 and enable the installation box 100 to block strong winds, but also reduce the impact of the bracket 200 and the installation box 100 on the arrester body 700 when the bracket 200 vibrates due to strong winds. This will be described in further detail later.

[0038] Furthermore, the arrester body 700 includes a silicone rubber insulating shell 710, the interior of the silicone rubber insulating shell 710 wraps a zinc oxide resistor, the upper and lower ends of the silicone rubber insulating shell 710 are fixed with mounting flanges 720, and the flange 720 is provided with a terminal post 740, the terminal post 740 passes through the silicone rubber insulating shell 710 and the terminal post 740 is connected to the zinc oxide resistor; the periphery of the terminal post 740 is fixedly wrapped with an elastic limiting ring 730.

[0039] It is worth noting that the elastic limiting ring 730 of the present invention is itself made of elastic insulating material and can play the role of insulation and elastic limiting, for example, it can be made of rubber material, etc., and no further limitation is made to the specific material here.

[0040] Furthermore, the limiting mechanism includes an installation box 100, a box cover 140 is fixedly installed on the top of the installation box 100, a bottom limiting hole 190 is opened through the center of the bottom of the installation box 100, and a top limiting hole 141 is opened through the center of the box cover 140; the elastic limiting rings 730 at the upper and lower ends of the lightning arrester body 700 are movably abutted against the side walls of the top limiting hole 141 and the side walls of the bottom limiting hole 190 respectively.

[0041] The present invention enables the arrester body 700 to be well limited and fixed by movably abutting the elastic limiting ring 730 wrapped around the terminal studs 740 at the upper and lower ends of the arrester body 700 with the side walls of the corresponding top limiting hole 141 and the side walls of the bottom limiting hole 190. At this time, the installation box 100 can block strong winds and protect the arrester body 700. At the same time, during the vibration of the bracket 200 and the installation box 100, the force acts on the elastic limiting ring 730. Under the buffering effect of the elastic limiting ring 730, the vibration of the arrester body 700 can be weakened, thereby reducing the probability of the arrester body 700 being damaged by vibration.

[0042] Furthermore, when the arrester body 700 is pulled to the upper part of the installation box 100, the terminal post 740 at the lower end of the arrester body 700 extends into the bottom limit hole 190, and the elastic limit ring 730 at the lower end of the arrester body 700 still abuts against the side wall of the bottom limit hole 190. Through this structural design, the arrester body 700 can still be limited and fixed when it moves up and down.

[0043] Furthermore, both sides of the bottom of the installation box 100 are fixedly connected with L-shaped fixing plates 120, and the L-shaped fixing plates 120 and the bottom of the installation box 100 form a plug-in slot, which is plugged into the bracket 200; the bottom of the L-shaped fixing plate 120 is threadedly connected with a fixing screw 130; threaded holes 220 are provided on both sides of the wiring hole 210, and the threaded holes 220 are threadedly connected with the corresponding fixing screws 130.

[0044] The present invention forms a plug-in slot with the L-shaped fixing plate 120 of the installation box 100 and the bottom of the installation box 100, which can not only improve the installation firmness of the installation box 100, but also does not affect the limit fixation of the lightning arrester body 700 and the subsequent line connection; specifically, when installation is required, since the lightning arrester body 700 and the installation box 100 are movably abutted, the lightning arrester body 700 is pulled to the upper part of the interior of the installation box 100 so that the terminal post 740 at the lower end of the lightning arrester body 700 can be extended into the bottom limit hole 190, so that the plug-in slot formed by the L-shaped fixing plate 120 and the bottom of the installation box 100 can be quickly plugged into the bracket 200; after the plug-in is completed, the lightning arrester body 700 is released. 0, so that the elastic limiting ring 730 at the lower end of the arrester body 700 passes through the bottom limiting hole 190 and the wiring hole 210 in turn, and finally the installation box 100 is fixedly installed on the bracket 200 by tightening the fixing screw 130; the installation firmness of the installation box 100 is improved by the combined effect of the limiting of the elastic limiting ring 730 at the lower end of the arrester body 700, the plug-in limiting of the L-shaped fixing plate 120 and the fixing screw 130, so that even if the fixing screw 130 is loose, due to the limiting of the elastic limiting ring 730 and the plug-in limiting of the L-shaped fixing plate 120, the installation box 100 and the arrester 700 can still be temporarily limited and fixed, and the subsequent line connection of the arrester body 700 is not affected.

[0045] It is worth noting that the structural dimensions of the drawings of the present invention are only schematic diagrams and can be flexibly adjusted according to actual conditions. No further limitation is imposed on the dimensions and they will not be described in detail herein.

[0046] Furthermore, the front and rear ends of the installation box 100 are both provided with ventilation slots 170, and four sliding holes 180 are penetrated through the installation box 100 located around the ventilation slots 170; a windproof mechanism 500 is provided on the sliding holes 180, and the windproof mechanism 500 includes a windshield 510; a sliding rod 520 is slidably connected to the front and rear corresponding sliding holes 180, and the ends of the sliding rod 520 located at the front and rear ends of the installation box 100 are respectively fixedly connected to a windshield 510.

[0047] Furthermore, a plurality of first ventilation holes 110 are provided at the left and right ends of the installation box 100; a slide groove 150 is provided inside the left and right side walls of the installation box 100, an adjustment plate 540 is slidably connected in the slide groove 150, and a plurality of second ventilation holes 541 are penetrated through the adjustment plate 540; the slide groove 150 is also connected to the interior of the installation box 100 through an avoidance slot 160, the adjustment plate 540 is fixedly connected with a slider 550, and the slider 550 is slidably connected to the corresponding avoidance slot 160; the slider 550 is fixedly connected to the middle part of the corresponding slide rod 520; two return springs 530 are sleeved on the slide rod 520, and the two ends of the return spring 530 are respectively fixedly connected to the adjacent installation box 100 and the slider 550.

[0048] Furthermore, when there is no wind, the first ventilation hole 110 is connected to the corresponding second ventilation hole 541; when the wind causes one of the wind shields 510 to close the adjacent ventilation slot 170, the first ventilation hole 110 and the corresponding second ventilation hole 541 are misaligned.

[0049] The present invention can have heat dissipation in the absence of wind and can ensure a certain heat dissipation while preventing wind in the presence of strong winds, thereby ensuring the normal operation of the arrester 700; specifically, when there is no wind, the first vent 110 is connected to the corresponding second vent 541, ensuring the heat dissipation of the left and right ends, and the wind shield 510 is open to the corresponding ventilation slot 170, ensuring the heat dissipation of the front and rear ends; when there is strong wind, the strong wind acts on the wind shield 510, so that the wind shield 510 and the corresponding adjacent ventilation slot 170 are closed, and the first vent 110 and the corresponding second vent 541 are staggered for wind protection, and the opening between the wind shield 510 and the corresponding second vent 541 on the opposite side becomes larger, thereby ensuring the heat dissipation and making the arrester 700 operate normally. Whether there is strong wind in the front or rear direction of the installation box 100, it can ensure that the opposite direction has good heat dissipation while preventing wind.

[0050] It is worth mentioning that the windproof mechanism 500 of the present invention will close the wind shield 510 and the corresponding adjacent ventilation slots 170 only in extremely windy weather. Under normal wind conditions, the wind shield 510 will only move a small section, thereby ensuring ventilation and heat dissipation under normal conditions. At the same time, the windproof mechanism 500 mainly protects against wind in the front and rear end directions. Since the left and right ends of the entire device are blocked by electric poles, it can play a certain wind-blocking role when encountering strong winds in the left and right directions. Only the cooperation of the first ventilation hole 110 and the second ventilation hole 541 can achieve the wind-blocking effect in all directions, which will not be described in detail here.

[0051] Furthermore, an anti-falling mechanism 600 is provided above one end of the L-shaped fixing plate 120 near the plug-in slot, and the anti-falling mechanism 600 includes a telescopic shell 610, and the telescopic shell 610 is fixedly connected to the installation box 100; a sliding block 640 is slidably connected to the inside of the telescopic shell 610; a telescopic slot 620 is provided through the bottom of the telescopic shell 610, and a limiting inclined block 650 is fixedly provided at the bottom of the sliding block 640, and the limiting inclined block 650 passes through the telescopic slot 620 and is arranged outward; a second return spring 660 is provided inside the telescopic shell 610, and the two ends of the second return spring 660 are fixedly connected to the telescopic shell 610 and the sliding block 640 respectively; a second slide groove 630 is provided through one side of the telescopic shell 610; a shift block 641 is fixedly connected to one end of the sliding block 640, and the shift block 641 is slidably connected to the second slide groove 630.

[0052] The present invention cooperates with the anti-falling mechanism 600. During the process of installing the installation box 100 on the bracket 200, the bracket 200 presses the limiting bevel 650, so that the limiting bevel 650 extends into the interior of the telescopic shell 610, thereby not affecting the installation of the installation box 100; after installation, the limiting bevel 650 is reset to prevent it from falling off. When the installation box 100 is released from the bracket 200 in the event of an emergency natural disaster, the L-shaped fixing plate 120 and the limiting bevel 650 of the anti-falling mechanism 600 form a closed notch to prevent the installation box 100 from falling from a high place; at the same time, when the installation box 100 needs to be disassembled, the closed notch can be opened by pushing the shifting block 641 upward to make the limiting bevel 650 extend into the interior of the telescopic shell 610.

[0053] A method for installing the above-mentioned windproof lightning arrester comprises the following steps:

[0054] S1. Pull the arrester body 700 to the upper part of the installation box 100 so that the terminal post 740 at the lower end of the arrester body 700 extends into the bottom limit hole 190;

[0055] S2. Insert the L-shaped fixing plate 120 and the plug-in slot formed at the bottom of the installation box 100 on the bracket 200. After the insertion, loosen the arrester body 700, so that the elastic limiting ring 730 at the lower end of the arrester body 700 passes through the bottom limiting hole 190 and the wiring hole 210 in sequence; tighten the fixing screw 130 to fix the installation box 100 on the bracket 200;

[0056] S3. Connect the ends of the terminal post 740 at the lower end of each lightning arrester body 700 in series through the connecting wire 300, and connect one end of the connecting wire 300 to the grounding electrode through the grounding flat iron; then connect the cable to the terminal post 740 at the upper end of the corresponding lightning arrester body 700 through the cable power line 400 to complete the installation.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
