Description

Technical Field

[0001] This utility model relates to the field of pole and tower technology, and in particular to shear-resistant wound composite material poles and towers. Background Technology

[0002] In many industries such as power and telecommunications, power poles serve as critical support facilities, and their performance directly affects the stability and safety of system operation. Traditional pole materials, such as steel and concrete, have significant limitations. While steel has high strength, it is susceptible to corrosion and requires frequent maintenance and replacement in harsh environments such as humidity and salinity, resulting in high costs. Concrete poles, on the other hand, are too heavy, posing numerous difficulties during transportation and installation, especially in areas with complex terrain, such as mountainous and hilly areas, where construction difficulty increases dramatically.

[0003] With the continuous expansion of modern engineering construction and the increasing demands for infrastructure durability, traditional poles and towers can no longer meet the needs of industry development.

[0004] On the one hand, with the frequent occurrence of extreme weather events such as strong typhoons and torrential rains, higher standards are being set for the wind resistance, pressure resistance, and shear resistance of power poles and towers. On the other hand, with the increase in fire risk during urban construction and industrial development, the flame-retardant performance of power poles and towers has also become a key consideration for ensuring public safety. Utility Model Content

[0005] The purpose of this invention is to provide a shear-resistant wound composite material tower, which solves the above-mentioned problems by using this device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a shear-resistant spiral composite material pole tower, including a pole tower body and a pole tower base. The pole tower base is fixed at the bottom of the pole tower body. A PE flame-retardant corrugated pipe protective sleeve is provided on the outside of the pole tower body. A flame-retardant layer is filled between the PE flame-retardant corrugated pipe protective sleeve and the pole tower body. A partition plate two is fixed at the bottom inside the pole tower body. A partition plate one is provided above the partition plate two.

[0007] Preferably, a filling cavity is formed between partition one and partition two, a filling cavity is provided on one side of the bottom of the tower body, one end of the filling cavity is connected to the filling cavity, and a sealing hole is provided on one side of the bottom of the tower base, the sealing hole corresponds to and is connected to the filling cavity, and a sealing bolt is threaded inside the sealing hole.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. The shear-resistant wound composite material pole provided by this utility model features a 3.5-meter-long filled cavity at the root of the pole body, constructed by partitions one and two, and filled with lightweight, high-strength, flame-retardant foam material. This significantly enhances the compressive and shear resistance of the root. Faced with external forces, especially the soil pressure and potential lateral forces borne by the landfill section, the pole remains stable, effectively reducing the risk of tilting or collapse and ensuring long-term stable operation.

[0010] 2. The shear-resistant spiral composite material pole provided by this utility model has a lightweight, high-strength, flame-retardant foam material that forms an efficient flame-retardant barrier in the cavity. When a fire occurs, it can significantly delay the spread of fire, reduce the damage to the internal structure of the pole, and provide comprehensive protection for the safety of the pole and surrounding facilities, thus providing solid protection against fire hazards in complex environments.

[0011] 3. The shear-resistant spiral composite material pole tower provided by this utility model simplifies the foaming material injection process by setting sealing holes and sealing bolts at the pole base. Construction personnel can easily unscrew the bolts to inject the material, and after foaming, screw the bolts back in to complete the sealing. Subsequent inspection or maintenance of the filled cavity can also be easily performed by opening the cavity, greatly improving construction efficiency and reducing maintenance costs.

[0012] 4. The shear-resistant spiral composite material pole tower provided by this utility model, with its PE flame-retardant corrugated pipe protective sleeve, provides physical protection for the outside of the pole tower body due to its good flexibility and impact resistance. It effectively blocks the collision and scratch of external objects, maintains the appearance and structural integrity of the pole tower, greatly extends the service life of the pole tower, and reduces the need for replacement and maintenance due to external damage.

[0013] 5. The shear-resistant spiral composite material pole provided by this utility model has a flame-retardant layer formed by the lightweight, high-strength flame-retardant foam material filling the space between the PE flame-retardant corrugated pipe protective sleeve and the main body of the pole. This layer works synergistically with the internal filling material to improve the flame-retardant performance of the pole from both the inside and outside. This provides a more comprehensive fire safety net for the pole in various complex environments and enhances its reliability in fire scenarios. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figures 1 to 4 As shown, the shear-resistant wound composite material pole of this utility model includes a pole body 1 and a pole base 2. The pole base 2 is fixed to the bottom of the pole body 1. A PE flame-retardant corrugated pipe protective sleeve 3 is provided on the outside of the pole body 1. A flame-retardant layer 31 is filled between the PE flame-retardant corrugated pipe protective sleeve 3 and the pole body 1. A second partition 41 is fixed to the bottom of the inside of the pole body 1. A first partition 4 is provided above the second partition 41.

[0022] A filling cavity is formed between partition 4 and partition 41. A filling cavity 42 is provided on one side of the bottom of the tower body 1. One end of the filling cavity 42 is connected to the filling cavity. A sealing hole 43 is provided on one side of the bottom of the tower base 2. The sealing hole 43 corresponds to and is connected to the filling cavity 42. A sealing bolt 44 is threaded inside the sealing hole 43.

[0023] Specifically, partition 4 and partition 41 form a filling cavity at the bottom of the tower body 1. The distance between partition 4 and partition 41 is 3.5 meters, and partition 4 and partition 41 are located at the root of the tower body 1. The sealing bolt 44 is unscrewed from the sealing hole 43, and lightweight high-strength flame-retardant foam material is injected into the filling cavity through the sealing hole 43 and the filling cavity 42. After the foam material in the filling cavity has finished foaming, the sealing bolt 44 is screwed into the sealing hole 43 for sealing.

[0024] A PE flame-retardant corrugated pipe protective sleeve 3 is installed on the outside of the main body 1 of the tower. A flame-retardant layer 31 is filled between the PE flame-retardant corrugated pipe protective sleeve 3 and the main body 1 of the tower. The flame-retardant layer 31 is made of lightweight, high-strength flame-retardant foam material.

[0025] A 3.5-meter-long cavity consisting of partition 4 and partition 41 is installed at the root of the main body 1 of the tower. Lightweight, high-strength, flame-retardant foam material is injected into the cavity. This effectively enhances the compressive and shear resistance of the tower root, allowing the tower to better resist pressure from the soil and potential lateral forces when subjected to external forces, especially in the backfill section. This improves the overall stability of the tower and reduces the risk of tilting or collapse.

[0026] Lightweight, high-strength, flame-retardant foamed materials have excellent flame-retardant properties and can form a flame-retardant barrier in the cavity. When the tower encounters a fire, it can slow the spread of the fire, reduce the damage to the internal structure of the tower, and ensure the safety of the tower and surrounding facilities.

[0027] By setting sealing holes 43 and sealing bolts 44 in the base 2 of the tower, the injection of foaming material is convenient. Construction personnel can easily unscrew the sealing bolts 44 to inject the material. After foaming is completed, the sealing bolts 44 are screwed in to complete the sealing. If it is necessary to inspect or maintain the filling cavity in the future, it can be easily opened again for operation.

[0028] The PE flame-retardant corrugated pipe protective sleeve 3 has good flexibility and impact resistance, and can provide physical protection for the exterior of the tower body 1. It can effectively resist mechanical damage such as collision and scratch from external objects to the tower, protect the appearance and structural integrity of the tower, and extend the service life of the tower.

[0029] The flame-retardant layer 31 formed by the lightweight, high-strength flame-retardant foam material filling between the PE flame-retardant corrugated pipe protective sleeve 3 and the tower body 1, works in conjunction with the internally filled foam material to further enhance the flame-retardant performance of the tower from both internal and external directions, providing more comprehensive fire protection for the tower and enhancing its safety in various complex environments.
