Description

Technical Field

[0001] This utility model relates to the field of lightning protection equipment technology, specifically a non-lightning-contact lightning protection device. Background Technology

[0002] In outdoor environments, lightning activity is frequent, which exposes various outdoor facilities to the risk of damage from lightning strikes. Non-intercepting lightning protection devices mainly achieve lightning protection through innovative mechanisms such as electric field interference and charge neutralization. Taking electric field interference as an example, some non-intercepting lightning protection devices have built-in electric field generators that can generate an electric field opposite to the electric field of thunderclouds, interfering with the distribution and movement of thundercloud charges, thereby inhibiting the development of downward lightning leaders.

[0003] Existing non-contact lightning protection devices lack angle adjustment capabilities when installed outdoors. Mountainous buildings may have steep roofs, communication towers may have different tilt angles, and outdoor billboards have various installation surfaces. Fixed-angle lightning protection devices are difficult to adapt to these complex installation environments, resulting in poor lightning protection performance and failing to fully leverage the advantages of non-contact lightning protection technology.

[0004] Therefore, a non-lightning-contact lightning protection device is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a non-lightning-contact lightning protection device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-lightning-contact lightning protection device, comprising a fixed base, an adjustment mechanism disposed inside the fixed base, the adjustment mechanism comprising a non-lightning-contact lightning protection body, the non-lightning-contact lightning protection body being located above the fixed base, a connecting block being fixedly connected to the bottom of the non-lightning-contact lightning protection body, a transmission rod being rotatably connected inside the fixed base, the transmission rod being fixedly connected to the connecting block, an auxiliary gear being fixedly connected to one end of the transmission rod, a moving rod being slidably connected inside the fixed base, a limiting tooth block being fixedly connected to one end of the moving rod near the auxiliary gear, the limiting tooth block meshing with the auxiliary gear, an auxiliary ring being fixedly connected to the outer surface of the moving rod, a fixed plate being fixedly connected to the other end of the moving rod, two guide rods being connected inside the fixed plate, the guide rods being inserted into the interior of the fixed base.

[0007] Preferably, in the above-mentioned non-lightning protection device, the end of the limiting tooth block near the auxiliary gear is provided with a circular groove, and an internal gear ring is provided on the inner sidewall of the circular groove. The auxiliary gear is inserted into the circular groove, and the internal gear ring meshes with the auxiliary gear.

[0008] Preferably, in the above-mentioned non-lightning protection device, the mounting base is fixedly connected to both sides of the mounting plate, and the mounting plate has two mounting holes inside.

[0009] Preferably, in the above-mentioned non-lightning protection device, a reinforcing block is fixedly connected between the mounting plate and the fixing base.

[0010] Preferably, in the above-mentioned non-lightning protection device, a guide block is fixedly connected to the outer surface of the limiting tooth block, and the guide block is slidably connected to the inside of the fixed base.

[0011] Preferably, in the above-mentioned non-lightning protection device, a return spring is sleeved on the outer surface of the movable rod, one end of the return spring is fixedly connected to the auxiliary ring, and the other end of the return spring is fixedly connected to the inner wall of the fixed base.

[0012] Preferably, in the above-mentioned non-lightning protection device, a pulling block is fixedly connected to the fixed plate, and the pulling block has a gripping groove inside.

[0013] The beneficial effects of this utility model are as follows: The transmission rod is locked by the meshing relationship between the limiting toothed block and the auxiliary gear. When the angle of the non-lightning-contact lightning protection body needs to be adjusted, the pulling block is moved, causing the fixed plate, moving rod, and limiting toothed block to move simultaneously. At this time, the limiting toothed block disengages from the auxiliary gear, the return spring is compressed, and the transmission rod can rotate freely, thus allowing the non-lightning-contact lightning protection body to be rotated manually. After adjustment, the pulling block is released, and the return spring drives the auxiliary ring to reset, causing the moving rod and limiting toothed block to move. The auxiliary gear is embedded in the circular groove on the right end of the limiting toothed block, and the internal gear ring in the circular groove meshes with the auxiliary gear again, thereby locking the position of the transmission rod. Because the angle of the non-lightning-contact lightning protection body is adjustable, it can adapt to complex installation environments, effectively increasing the lightning protection effect and fully leveraging the advantages of non-lightning-contact lightning protection technology.

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0017] like Figures 1-4 As shown, a non-lightning-contact lightning protection device includes a fixed base 1, and an adjustment mechanism 2 is provided inside the fixed base 1. The adjustment mechanism 2 includes a non-lightning-contact lightning protection body 201, which is located above the fixed base 1. A connecting block 202 is fixedly connected to the outer surface of the non-lightning-contact lightning protection body 201. A transmission rod 203 is rotatably connected inside the fixed base 1, and an auxiliary bearing 210 is sleeved on the outer surface of the transmission rod 203. The auxiliary bearing 210 is embedded inside the fixed base 1.

[0018] The outer surface of the transmission rod 203 is fixedly connected to the inner wall of the connecting block 202, and an auxiliary gear 204 is fixedly connected to one end of the transmission rod 203. Mounting plates 211 are fixedly connected to both sides of the fixed base 1. Each mounting plate 211 has two mounting holes 212 inside. The mounting plate 211 is fixed in place by passing external bolts through the mounting holes 212, thus completing the installation of the fixed base 1. A reinforcing block 213 is fixedly connected to the upper surface of each mounting plate 211 to improve structural strength.

[0019] A movable rod 205 is slidably connected inside the fixed base 1. A limiting tooth block 206 is fixedly connected to the right end of the movable rod 205. A circular groove is provided at one end of the limiting tooth block 206 near the auxiliary gear 204. An internal gear ring is provided on the inner side wall of the circular groove. The auxiliary gear 204 can be inserted into the circular groove, and the internal gear ring in the limiting tooth block 206 can mesh with the auxiliary gear 204.

[0020] A guide block 214 is fixedly connected to the outer surface of the limiting tooth block 206. The guide block 214 is slidably connected to the inside of the fixed base 1. The guide block 214 can move simultaneously with the limiting tooth block 206 and use the friction force generated by itself on the fixed base 1 during the movement to improve the stability of the limiting tooth block 206 during movement, thereby increasing the stability of the device.

[0021] An auxiliary ring 207 is fixedly connected to the outer surface of the moving rod 205, and a fixing plate 208 is fixedly connected to the other end of the moving rod 205. A return spring 215 is sleeved on the outer surface of the moving rod 205. The return spring 215 is fixedly connected to the auxiliary ring 207, and the other end of the return spring 215 is fixedly connected to the inner wall of the fixing seat 1. The return spring 215 can apply pressure to the auxiliary ring 207 using its own elastic force, so that the moving rod 205 has the ability to automatically return.

[0022] The fixed plate 208 has two guide rods 209 slidably connected inside. Each guide rod 209 is inserted into the fixed base 1, and one end of each guide rod 209 is provided with an external thread, which is threaded to the fixed base 1. The other end of the guide rod 209 is provided with a baffle plate, which is used to limit the position of the fixed plate 208. A pulling block 216 is fixedly connected to the fixed plate 208. The pulling block 216 has a gripping groove 217 inside, which facilitates pulling the fixed plate 208.

[0023] Working principle: When in use, the fixed base 1 is first fixed in a suitable position by the mounting plate 211 and the mounting hole 212. When it is necessary to adjust the angle of the non-lightning protection body 201, the pulling block 216 is moved by the gripping groove 217, which drives the fixed plate 208, the moving rod 205 and the limiting tooth block 206 to move at the same time. At this time, the limiting tooth block 206 disengages from the auxiliary gear 204, and the return spring 215 is compressed. At this time, the transmission rod 203 can rotate freely, so the non-lightning protection body 201 can be rotated manually, and the transmission rod 203 rotates in the fixed base 1 accordingly. After adjustment, release the pull block 216. The return force generated by the return spring 215 drives the auxiliary ring 207 to reset, and drives the moving rod 205 and the limiting tooth block 206 to move. The auxiliary gear 204 is embedded in the circular groove at the right end of the limiting tooth block 206. The internal gear ring in the circular groove meshes with the auxiliary gear 204 again, thereby locking the position of the transmission rod 203.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
