Description

Technical Field

[0001] This utility model relates to the field of single-tube tower technology, and in particular to a height-reducing lightning protection single-tube tower. Background Technology

[0002] In recent years, with the increase in flight routes, communication towers near airports often need to be lowered to meet signal and air traffic control requirements. After the height reduction, the original lightning rod on the top of the tower is no longer suitable, and it is often replaced by a pole-mounted lightning rod installed on the side of the tower, while the removed section is recycled as scrap. However, in this process, an opening is formed at the connection between the remaining tower section and the removed section, which is prone to water accumulation.

[0003] The current solution is to first measure the top dimensions of the remaining tower section, then weld and seal it with suitable steel plates at high altitude, apply anti-rust paint, and finally install the lightning rod at high altitude. This method has the problems of high-altitude operation being highly dangerous and complicated procedures. Utility Model Content

[0004] The purpose of this utility model is to provide a height-reducing lightning protection single-tube tower to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

Detailed Implementation

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Reference Figures 1 to 4 This utility model provides a height-reducing single-tube lightning protection tower, and the following embodiments are provided:

[0030] In some embodiments, a height-reducing lightning protection monotube tower includes a top tower section 100, a connecting section 200, and a bottom tower section 300. The upper section of an existing, taller monotube tower is cut off to form the top tower section 100, the middle section is dismantled and recycled, and the remaining section forms the bottom tower section 300. The connecting section 200 is then fitted onto the lower end of the top tower section 100. Finally, a hoisting device is used to hoist and insert the top tower section 100 and the connecting section 200 onto the upper end of the bottom tower section 300. This achieves both a reduction in the height of the monotube tower and lightning protection. The lightning rod can be replaced as needed; if replacement is required, the top tower section 100 can be lowered to the bottom for replacement, improving safety.

[0031] Specifically, the top of the connecting section 200 is provided with an annular plate 210, the annular plate 210 has an insertion port 211 in the middle, the bottom of the connecting section 200 is provided with an annular support plate 220, and the lower end of the top tower section 100 is inserted from the insertion port 211 and placed on the annular support plate 220.

[0032] Because the cross-sections of the connecting section 200 and the top tower section 100 are smaller at the top and larger at the bottom, the connecting section 200 will snap into the lower end of the top tower section 100. After the connecting section 200 is installed, the top tower section 100 is lifted as a whole so that the connecting section 200 is inserted into the upper end of the bottom tower section 300. This utility model can retain the tower section with the annular support rod in the top tower section 100, improving the utilization rate of the tower section, while eliminating the need for high-altitude welding and reducing high-altitude operations.

[0033] Reference Figure 2 An annular support plate 220 has an annular baffle 221 extending upward from its inner edge. The annular baffle 221 is inserted into the lower end of the top tower section 100, which can further fix the top tower section 100, making the connection more secure.

[0034] To improve the connection effect, multiple first fixing screws 222 are also provided. The multiple first fixing screws 222 are arranged in a ring at intervals on the inner side of the annular baffle 221. The first fixing screws 222 are sequentially threaded to the annular baffle 221 and the top tower section 100, further improving the structural stability.

[0035] The upper end of the annular plate 210 is provided with an annular fixing plate 212 extending upward. The annular fixing plate 212 is attached to the outer periphery of the top tower section 100 to further fix the top tower section 100 and improve the connection strength.

[0036] To improve the connection effect, multiple second fixing screws 213 are also provided. The multiple second fixing screws 213 are arranged in a ring at intervals on the outer periphery of the annular fixing plate 212. The second fixing screws 213 are sequentially threaded to the annular fixing plate 212 and the top tower section 100, further improving the structural stability.

[0037] In order to improve the connection strength between the connecting section 200 and the bottom tower section 300, a plurality of third fixing screws 240 are provided between the connecting section 200 and the bottom tower section 300.

[0038] Meanwhile, in order to further improve the water-blocking effect, the lower surface of the annular plate 210 abuts against the top of the bottom tower section 300.

[0039] In other embodiments, reference is made to Figure 3An annular sleeve 230 is provided between the annular plate 210 and the annular support plate 220. The top tower section 100 is fitted inside the annular sleeve 230. Since the cross-section of the annular sleeve 230 is smaller at the top and larger at the bottom, the annular sleeve 230 is integrally formed with the connecting section 200. The top tower section 100 is fitted inside the annular sleeve 230, which further improves the connection strength between the top tower section 100 and the annular sleeve 230.

[0040] Specifically, the cross-section of the annular sleeve 230 adopts a tapered or trapezoidal design with a smaller top and a larger bottom. This design not only optimizes the structural strength but also allows the top tower section 100 to gradually adapt to and tightly fit the inner wall of the annular sleeve 230 during insertion. As the insertion depth increases, the contact area between the top tower section 100 and the annular sleeve 230 gradually increases, thereby improving the stability and reliability of the connection.

[0041] Integration of the annular sleeve 230 and the connecting section 200: The annular sleeve 230 and the connecting section 200 are designed as a single unit, meaning there are no additional connectors or seams between them, thus avoiding a decrease in connection strength due to loosening or damage of connectors. This integrated design not only simplifies the structure but also improves the overall strength and durability.

[0042] Because the cross-section of the annular sleeve 230 is designed to be smaller at the top and larger at the bottom, when the top tower section 100 is fitted in, its lower end will be subjected to greater pressure, thereby generating greater friction with the inner wall of the annular sleeve 230. This friction helps to firmly lock the top tower section 100 inside the annular sleeve 230, preventing it from loosening or falling off.

[0043] In addition, the top tower section 100 is also fitted with a flow guide sleeve 250, which covers the top of the connecting section 200. The flow guide sleeve 250 is formed by two annular baffles 221, the two edges of which overlap and are fixed by waterproof screws. Water flows down along the flow guide sleeve 250, reducing rainwater accumulation on the upper surface of the annular plate 210. The annular baffles 221 can be made of stainless steel or rubber.

[0044] This invention utilizes the characteristic that a single-tube tower is composed of multiple tower sections connected end-to-end to modify single-tube towers requiring height reduction and lightning protection. The number of tower sections to be removed is calculated based on the desired height reduction. The upper section of the existing taller single-tube tower is cut as the top section 100, the middle section is removed and recycled, and the remaining section becomes the bottom section 300. A connecting section 200 is then fitted onto the lower end of the top section 100. Finally, using hoisting equipment, the top section 100 and the connecting section 200 are hoisted and installed onto the upper end of the bottom section 300, achieving both height reduction and lightning protection. Furthermore, the connecting section 200 can be fabricated by cutting and using the recycled middle section. This modification method is simple and practical, reusing dismantled tower sections and avoiding the risks associated with installing lightning rods and sealing the tower top at high altitudes.

[0045] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
