Description

Technical Field

[0001] This utility model relates to the field of lightning protection device technology, and more specifically, to a lightning arrester rod. Background Technology

[0002] Lightning rods are common direct lightning protection devices. They are rod-shaped conductors that attract lightning and cause it to fall into the ground, protecting buildings and tall trees from lightning strikes.

[0003] Traditional lightning rods are typically one-piece long pole structures, which present numerous inconveniences in transportation, installation, and subsequent maintenance. This is especially true for taller lightning rods, which are difficult to transport, complex to hoist and install, and require complete replacement if partially damaged, resulting in high costs. Furthermore, traditional connection methods often use direct flange bolt connections, where the strength and anti-loosening performance of the connection are crucial for withstanding long-term wind loads and lightning strikes; ordinary structures often fail to simultaneously meet the requirements of convenient installation and reliable connection. Utility Model Content

[0004] The purpose of this invention is to provide a lightning rod for weather radar to solve the problems of inconvenient transportation, difficult installation, and insufficient connection reliability of existing lightning rods.

[0005] To address the aforementioned problems, this utility model first provides a lightning rod for a weather radar, comprising: a base portion, the cross-sectional area of ​​which gradually increases from top to bottom, forming a first hollow channel inside, with at least one first sliding track along the axial direction on the inner sidewall, and a first limiting mounting groove communicating with the top of the first sliding track in the circumferential direction; a first limiting annular surface formed on its upper end surface, with a first connecting hole communicating with the first limiting mounting groove on the first limiting annular surface, and a first mating hole corresponding to the position below the first limiting mounting groove; a mounting flange at its lower end for mounting the lightning rod next to the weather radar; a connecting middle section portion, cylindrical in shape, with a second hollow channel inside, the connecting middle section portion being accommodated within the first hollow channel; at least one first slider portion on its outer sidewall, which can slide and engage with the first sliding track, the first slider portion having a first through hole; when the first slider portion slides along the first sliding track to the top, rotating the connecting middle section portion can position the first slider portion at the top. Within the first limiting mounting groove, the first fastener sequentially passes through the first connecting hole, the first through hole, and the first connecting hole to connect the connecting middle section and the base section. Its inner sidewall is provided with at least one second sliding track along the axial direction, and the top of the second sliding track is adjacent to a second limiting mounting groove that communicates with it in the circumferential direction. A second limiting ring surface is formed on its upper end face, and a second connecting hole communicating with the second limiting mounting groove is opened on the second limiting ring surface. A second mating hole is provided at a corresponding position below the second limiting mounting groove. The rod head can be accommodated within the second hollow channel, and its bottom is provided with at least one second slider that can mate with the second sliding track. A second through hole is opened on the second slider. When the second slider slides along the second sliding track to the top, rotating the rod head allows the second slider to be placed within the second limiting mounting groove. At this time, the rod head and the connecting middle section are connected by the second fastener sequentially passing through the second connecting hole, the second through hole, and the second connecting hole.

[0006] Furthermore, both the connecting middle section and the outer side wall of the rod head are provided with lifting rings or lugs for hoisting.

[0007] Furthermore, the inner wall of the first hollow channel is symmetrically provided with two first sliding tracks along the axial direction, and the outer wall of the connecting middle section is symmetrically provided with two first sliders.

[0008] Furthermore, the inner wall of the second hollow channel is symmetrically provided with two second sliding tracks along the axial direction, and the outer wall of the rod head is symmetrically provided with two second sliders.

[0009] Furthermore, a first shielding cover is provided on the first limiting ring surface, a first magnetic element is provided on its lower end surface, and a second magnetic element is provided on the upper end surface of the first limiting ring surface. The first shielding cover is attached to and covers the top of the first limiting ring surface by magnetic attraction.

[0010] Furthermore, the first shielding cover is semi-circular, and two of the first shielding covers can be engaged and snapped together to completely cover the first limiting ring surface.

[0011] Furthermore, a second shielding cover is provided on the second limiting ring surface, a third magnetic element is provided on its lower end surface, and a fourth magnetic element is provided on the upper end surface of the second limiting ring surface. The second shielding cover is attached to and covers the upper part of the second limiting ring surface by magnetic attraction.

[0012] Furthermore, the second shielding cover is semi-circular, and two second shielding covers can be engaged and snapped together to completely cover the second limiting ring surface.

[0013] The advantages of this utility model are:

[0014] The lightning rod is divided into three independent modules: a base, a connecting middle section, and a rod head, greatly reducing transportation difficulty and cost. If a part is damaged, it can be replaced specifically, without the need for complete scrapping, resulting in low maintenance costs. The combination of sliding, rotating, and locking connections ensures accurate guidance and simple operation, significantly improving installation efficiency. The cooperation between the slider and the limiting mounting groove, along with the lateral locking of the fasteners, forms multiple layers of protection, ensuring the mechanical strength and stability of the connections between components and effectively resisting wind loads and lightning strikes. A magnetic shielding cover on the limiting ring surface effectively seals key connection points, preventing rainwater accumulation and dust intrusion, significantly reducing the risk of corrosion and extending the overall lifespan of the equipment. Symmetrically arranged sliding rails and sliders ensure structural balance and stability, while the tapered design of the base (larger at the bottom and smaller at the top) provides excellent anti-overturning capability. This structural design is particularly suitable for applications requiring high-reliability protection, such as weather radar stations. Attached Figure Description

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0023] like Figures 1 to 2 As shown, the lightning rod for weather radar provided by this utility model is coaxially assembled from three sections: a base part 1, a connecting middle section 2, and a rod head 3.

[0024] The base portion 100 has a gradually increasing cross-sectional area downwards, and a mounting flange 105 is provided at the bottom, allowing it to be securely installed on the weather radar foundation using anchor bolts. The base portion 100 has a first hollow channel 101 inside, preferably with two first sliding rails 102 symmetrically arranged on its inner wall. The top of each first sliding rail 102 is connected to a circumferential first limiting mounting groove 103. Two first connecting holes are formed on the first limiting annular surface 104 at the upper end of the base portion 100, and a first mating hole is formed below the first limiting mounting groove 103.

[0025] The connecting middle section 200 is a cylindrical steel rod with two first sliders symmetrically fixed on its outer side. Each first slider has a first through hole. During installation, the connecting middle section 200 can be lifted using the lifting lugs 301 on its outer side, allowing the first sliders to slide upwards along the first sliding track 102. When the sliders reach the top of the track, the connecting middle section 200 is rotated smoothly, causing the first sliders to enter the first limiting mounting groove 103. At this time, the first fastener 106 (such as a bolt) is passed through the first connecting hole and the first through hole from the outside, and finally locked with the thread in the first mating hole, thus completing the fixation of the connecting middle section 200 and the base section 100. The interior of the connecting middle section 200 is a second hollow channel 201, and its inner wall is also symmetrically provided with a second sliding track 202 and a second limiting mounting groove 203. A second connecting hole is opened on the upper second limiting ring surface 204, and a second mating hole is opened at a corresponding position below the second limiting mounting groove 203.

[0026] Two second sliders are symmetrically provided at the bottom of the rod head 300, and the sliders have second through holes. The installation method is the same as that of the connecting middle section 200: the second slider is placed in the second hollow channel 201, slides up the second sliding track 202 to the top, rotates and is locked into the second limiting mounting groove 203, and then the second fastener 205 (such as a bolt) passes through the second connecting hole and the second through hole and is locked with the thread in the second mating hole.

[0027] To protect the connection points, two semi-circular first protective covers 109 are provided on the first limiting ring surface 104. The lower end of each cover has a first magnetic element (such as a magnet) embedded in it, which attracts to a second magnetic element (not shown in the figure) on the first limiting ring surface 104, thus tightly sealing the ring surface and completely covering the exposed portion of the first limiting ring surface 104, providing rain and dust protection. The second limiting ring surface 204 also uses a second protective cover based on the same principle for protection.

[0028] This embodiment scientifically decomposes the lightning rod into three core modules: the base, the connecting middle section, and the rod head. This completely solves the problem of difficult transportation of traditional integrated high poles, allowing each section to be transported and handled independently, greatly reducing logistics costs and on-site hoisting difficulty. Furthermore, when any module is damaged, it can be precisely replaced, avoiding the scrapping of the entire structure and significantly reducing maintenance costs throughout its lifecycle. The unique three-level connection mechanism of sliding guide, rotational positioning, and lateral locking not only makes on-site installation simple and intuitive with a high fault tolerance rate, but also achieves automatic centering and precise positioning of each component through the precise cooperation of the slider and the limiting groove. Finally, the locking force applied by the fasteners forms a rigid connection resistant to wind loads, vibration, and lightning strikes, ensuring a stable and reliable overall structure. The magnetic shielding cover design further provides a seamless physical barrier for the core connection areas, effectively preventing the intrusion of rainwater, humid air, and corrosive dust, fundamentally preventing electrochemical corrosion and rust on the connecting fasteners and contact interfaces, and greatly extending the service life of the lightning rod in harsh outdoor environments.

Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
