Description

Technical Field

[0001] This invention relates to the field of antenna structure technology, and in particular to a lightweight, high-strength antenna structure with combined lightning protection function. Background Technology

[0002] Existing medium-wave antennas are typically tall structures, reaching 32 meters in height, requiring lightning protection. This is usually achieved by installing a separate lightning rod next to the antenna. Such a design not only increases material and floor space requirements but is also aesthetically unappealing. Common medium-wave antennas are often fishbone-shaped with an open structure. To improve the antenna's wind resistance and the efficiency of the pole's signal radiation (efficiency is related to the space area constructed by the pole), the entire antenna must be made quite heavy and bulky, increasing manufacturing difficulty and construction costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a lightweight, high-strength antenna structure with composite lightning protection function, which can overcome the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A lightweight, high-strength antenna structure with composite lightning protection function is located at the top of an antenna tower, including a lightning rod tip, a central rod, a steel wire rope, a crossbar, a diagonal rod, a first conductor, a metal disk, and an inductor; the central rod and the crossbar are made of high-strength carbon fiber material, and the diagonal rod is made of high-strength glass fiber material;

[0006] The metal disk is horizontally positioned, the central rod is vertically positioned at the center of the metal disk, the tip of the lightning rod is located at the top of the central rod, one end of each of the multiple horizontal rods is connected to the middle of the central rod and the multiple horizontal rods are evenly spaced, the other end of each horizontal rod is connected to the edge of the metal disk via an oblique rod, the top of the central rod is connected to the other end of the multiple horizontal rods one by one via multiple obliquely arranged steel wire ropes and then connected to the edge of the metal disk, the other ends of the multiple horizontal rods are connected sequentially via a horizontally arranged circular steel wire rope; the metal disk is electrically connected to an inductor via a first conductor.

[0007] The beneficial effects of this invention are as follows:

[0008] This invention provides a lightweight, high-strength antenna structure with composite lightning protection function, comprising a lightning rod tip, a central rod, steel wire ropes, crossbars, diagonal rods, a first conductor, a metal disk, and an inductor. The central rod and crossbars are made of high-strength carbon fiber, while the diagonal rods are made of high-strength glass fiber. These components form the overall framework of the antenna, and the use of composite materials significantly reduces the antenna's weight, while maintaining the required strength and rigidity. The inclined steel wire ropes extend from the lightning rod tip and are fixed at their bottom to the metal disk. Horizontally arranged, circular steel wire ropes connect the diagonal rods. This wire rope network not only increases the structure's robustness but also, together with the lightning rod tip, prevents direct lightning strikes to the antenna, while simultaneously improving the antenna's signal radiation efficiency.

[0014] Please refer to Figure 1 as well as Figure 2 The present invention provides a lightweight, high-strength antenna structure with composite lightning protection function, which is located at the top of an antenna tower and includes a lightning rod tip, a central rod, a steel wire rope, a crossbar, a diagonal rod, a first conductor, a metal disk, and an inductor; the central rod and the crossbar are made of high-strength carbon fiber material, and the diagonal rod is made of high-strength glass fiber material;

[0015] The metal disk is horizontally positioned, the central rod is vertically positioned at the center of the metal disk, the tip of the lightning rod is located at the top of the central rod, one end of each of the multiple horizontal rods is connected to the middle of the central rod and the multiple horizontal rods are evenly spaced, the other end of each horizontal rod is connected to the edge of the metal disk via an oblique rod, the top of the central rod is connected to the other end of the multiple horizontal rods one by one via multiple obliquely arranged steel wire ropes and then connected to the edge of the metal disk, the other ends of the multiple horizontal rods are connected sequentially via a horizontally arranged circular steel wire rope; the metal disk is electrically connected to an inductor via a first conductor.

[0016] As can be seen from the above description, the beneficial effects of the present invention are as follows:

[0017] This invention provides a lightweight, high-strength antenna structure with composite lightning protection function, comprising a lightning rod tip, a central rod, steel wire ropes, crossbars, diagonal rods, a first conductor, a metal disk, and an inductor. The central rod and crossbars are made of high-strength carbon fiber, while the diagonal rods are made of high-strength glass fiber. These components form the overall framework of the antenna, and the use of composite materials significantly reduces the antenna's weight, while maintaining the required strength and rigidity. The inclined steel wire ropes extend from the lightning rod tip and are fixed at their bottom to the metal disk. Horizontally arranged, circular steel wire ropes connect the diagonal rods. This wire rope network not only increases the structure's robustness but also, together with the lightning rod tip, prevents direct lightning strikes to the antenna, while simultaneously improving the antenna's signal radiation efficiency.

[0018] Furthermore, a second wire for radiating signals is installed inside the inclined rod. One end of the second wire is connected to the crossbar, and the other end of the second wire is connected to the metal disk.

[0019] As described above, installing a second conductor inside the diagonal rod for radiating signals can further improve the antenna signal radiation efficiency.

[0021] As can be seen from the above description, the above connection method enables electrical signal conduction with devices located on the ground.

[0022] Furthermore, the number of the crossbars, diagonal bars, and inclined wire ropes are all eight.

[0023] As described above, the eight horizontal bars are arranged in an eight-eight-part circle, and the diagonal bars and steel wire ropes are set one-to-one with the horizontal bars to form the overall framework of the antenna. The strength and rigidity of the antenna structure meet the usage requirements.

[0024] Furthermore, the metal disk is made of copper.

[0025] As described above, the metal disk is made of copper and is used for assembly and electrical signal transmission.

[0026] Furthermore, the metal disk is circular in shape.

[0027] Furthermore, the radius of the metal disk is smaller than the length of the crossbar.

[0028] As can be seen from the above description, the design can make the overall cross-section resemble a rhombus, and the tensile tension of the wire rope is relatively stable, thus making the overall structure more stable.

[0029] Please refer to Figure 1 and Figure 2 Embodiment 1 of the present invention is as follows:

The metal disk is made of copper, hereinafter referred to as the copper disk. The copper disk is circular, and its radius is smaller than the length of the crossbar.

[0031] The copper disk is horizontally positioned, and the central rod 2 is vertically positioned at the center of the copper disk. The lightning rod tip 1 is located at the top of the central rod 2. In this embodiment, there are eight horizontal rods 4, eight diagonal rods 5, and eight inclined steel wire ropes 3. That is, one end of each of the eight horizontal rods is connected to the middle of the central rod, and the eight horizontal rods are evenly spaced, arranged in an eight-part circle. The other end of each horizontal rod 4 is connected to the edge of the copper disk via an inclined rod 5. A second conductor 6 for radiating signals is installed inside the inclined rod 5. One end of the second conductor 6 is connected to the horizontal rod, and the other end is connected to the copper disk, which further improves the antenna signal radiation efficiency.

[0032] The top of the central rod 2 is connected to the other end of the eight crossbars 4 one by one by eight inclined steel wire ropes 3, and then fixed to the edge of the copper plate. Then, the other ends of the eight crossbars 4 are connected in sequence by a horizontally ringed steel wire rope 3.

[0033] The copper disk is electrically connected to one end of the inductor 9 via the first wire 8, and the other end of the inductor 9 is connected to the device located on the ground via the lead wire 10 to realize the conduction of electrical signals.

[0034] In summary, this invention provides a lightweight, high-strength antenna structure with composite lightning protection function, comprising a lightning rod tip, a central rod, steel wire ropes, crossbars, diagonal rods, a first conductor, a metal disk, and an inductor. The central rod and crossbars are made of high-strength carbon fiber, while the diagonal rods are made of high-strength glass fiber. These components form the overall framework of the antenna, and the use of composite materials significantly reduces the antenna's weight, while maintaining the required strength and rigidity.
