Description

Technical Field

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

[0002] In the construction of modern power and communication infrastructure, power poles and towers serve as key supporting structures for overhead lines and communication antennas, and their performance directly affects the reliability and stability of system operation. Traditional power poles and towers mainly fall into three categories: wooden poles and towers, cement poles and towers, and steel poles and towers.

[0003] As key supporting facilities for power transmission lines in the power transmission system, power poles are crucial for ensuring stable power transmission.

[0004] However, existing towers still have some problems: In terms of structural strength, once they encounter extreme weather such as strong winds and blizzards, or due to the increased load on the transmission lines, stress concentration is likely to occur in local areas, making it difficult for the overall structural strength to support the structure and facing the risk of damage or even collapse; in terms of mechanical performance, there are shortcomings in axial, radial and tangential performance, poor resistance to deformation, bending and torsion, poor stability under complex stress conditions, and easy to deform and tilt. Utility Model Content

[0005] The purpose of this invention is to provide a reinforced pultruded composite material tower, which solves the above-mentioned problems when used in operation.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a reinforced pultruded composite material pole tower, including a support base and a pole tower body. The pole tower body is provided on the top of the support base, and a fixing seat is fixed on the bottom of the pole tower body. An external reinforcing component is provided on the outer wall of the pole tower body, and a reinforcing rib is fixed on the inner wall of the pole tower body. The bottom end of the reinforcing rib is fixedly connected to the top of the fixing seat.

[0007] Preferably, the reinforcing ribs are evenly distributed on the inner wall of the tower body, and the reinforcing ribs are set at the corners of the inner wall of the tower body.

[0008] Preferably, the external reinforcement component includes a first connecting seat fixed to the outer wall of the tower body, and a second connecting seat with the same number and position as the first connecting seat on the outer periphery of the top of the support base. A steel rope is provided between each corresponding first connecting seat and second connecting seat, with one end of the steel rope connected to the first connecting seat and the other end of the steel rope connected to the second connecting seat.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The reinforced pultruded composite material pole tower provided by this utility model significantly expands the connection area and contact points with other structures by cleverly arranging reinforcing ribs on the inner wall of the pole tower body. The auxiliary reinforcement of the reinforcing ribs can evenly distribute the external force borne to a larger area, effectively avoiding stress concentration and comprehensively improving the overall structural strength of the pole tower body. This allows the pole tower to bear loads far exceeding those of the past, easily coping with the heavy load tests brought by extreme weather such as icing and strong winds, significantly reducing the risk of deformation and damage due to excessive load, and laying a solid foundation for the stable operation of power and communication lines.

[0011] 2. The reinforced pultruded composite material tower provided by this utility model has reinforcing ribs that can efficiently transmit and disperse forces in multiple directions, including axial, radial, and tangential. After being installed on the inner wall, the tower body's resistance to deformation, bending, and torsion is comprehensively enhanced. Regardless of the complex stress conditions, it can maintain good stability, effectively reduce structural damage caused by insufficient mechanical properties, and greatly extend the service life of the tower.

[0012] 3. The reinforced pultruded composite material tower provided by this utility model has reinforcing ribs on its inner wall that act as a stable internal support frame. When subjected to dynamic loads such as wind loads and seismic forces, it can significantly reduce the vibration and deformation of the tower, effectively preventing swaying and tilting, ensuring safe and reliable operation under various harsh working conditions, significantly improving the tower's adaptability to complex environments, and guaranteeing the continuous operation of the line under extreme conditions.

[0013] 4. The reinforced pultruded composite material tower provided by this utility model, with the help of a steel cable cable tie system precisely installed on the side wall of the tower body via a connecting seat, can cleverly convert part of the horizontal force into its own tension when horizontal force is applied, and transfer it to the ground or foundation through a reasonable angle, significantly reducing the horizontal bending moment. This greatly enhances the horizontal stability of the tower, effectively preventing tilting and collapse accidents caused by excessive horizontal force. Especially in strong wind environments, it can also optimize the dynamic characteristics of the tower, significantly reduce wind vibration amplitude, and improve operational safety.

[0014] 5. The reinforced pultruded composite material pole tower provided by this utility model features steel cables that are pulled diagonally upwards from all four sides of the tower body, bearing part of the vertical load and transmitting it to the foundation and other supporting structures. This not only reduces the pressure on the main tower structure and lowers the risk of crushing and deformation, but also serves as a powerful auxiliary load-bearing means in scenarios where the vertical load increases, such as with the addition of equipment or the number of transmission line circuits. Working in conjunction with the main tower structure, it enhances the overall load-bearing capacity, ensuring the tower remains stable under varying loads and meeting the ever-growing needs of infrastructure construction.

[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 3 As shown, the reinforced pultruded composite material pole of this utility model includes a support base 1 and a pole body 2. The pole body 2 is provided on the top of the support base 1, and a fixing seat 3 is fixed on the bottom of the pole body 2. An external reinforcing component is provided on the outer wall of the pole body 2, and a reinforcing rib 5 is fixed on the inner wall of the pole body 2. The bottom end of the reinforcing rib 5 is fixedly connected to the top of the fixing seat 3.

[0022] The reinforcing ribs 5 are evenly distributed on the inner wall of the tower body 2, and the reinforcing ribs 5 are set at the corners of the inner wall of the tower body 2.

[0023] The external reinforcement components include a connecting seat 4 fixed to the outer wall of the tower body 2. The outer periphery of the top of the support base 1 is provided with connecting seats 42 of the same number and corresponding positions as the connecting seats 4. A steel cable 41 is provided between each corresponding connecting seat 4 and connecting seat 42. One end of the steel cable 41 is connected to the connecting seat 4, and the other end of the steel cable 41 is connected to the connecting seat 42.

[0024] Specifically, multiple reinforcing ribs 5 are evenly spaced at each corner of the inner wall of the tower body 2. The reinforcing ribs 5 increase the connection area and contact points between the inner wall of the tower body 2 and other structures. By setting the reinforcing ribs 5, the external force borne by the tower body 2 can be distributed to a larger area, avoiding stress concentration in local areas, thereby improving the overall strength and load-bearing capacity of the tower body 2 and enabling it to withstand greater loads.

[0025] The use of reinforcing ribs 5 can enhance the mechanical properties of the tower body 2 in multiple directions such as axial, radial and tangential, improve the deformation resistance, bending resistance and torsion resistance of the tower body 2, and enable the tower body 2 to maintain good stability under different stress conditions.

[0026] The installation of reinforcing ribs 5 on the inner wall of the tower body 2 is equivalent to constructing a supporting frame inside, which can enhance the overall stability of the tower body 2 structure. Especially when the tower body 2 is subjected to dynamic loads such as wind loads and seismic forces, the reinforcing ribs 5 can effectively reduce the vibration and deformation of the tower, prevent the tower body 2 from swaying, tilting and other unstable phenomena, and ensure that the tower body 2 can operate safely and reliably under various working conditions.

[0027] The steel cable 41 is installed on the side wall of the tower body 2 through connecting seat 1 4 and connecting seat 2 42. When a horizontal force is applied to the tower body 2, the steel cable 41 can convert part of the horizontal force into its own tension by being pulled at an angle. The force is then transferred to the ground or foundation through the angle of the steel cable 41, thereby reducing the horizontal bending moment borne by the tower body 2, improving the horizontal stability of the tower body 2, and effectively preventing the tower body 2 from tilting or collapsing due to excessive horizontal force. In strong wind conditions, the steel cable 41 can change the dynamic characteristics of the tower body 2 and reduce the vibration amplitude of the tower body 2 under wind action.

[0028] The steel cable 41 is diagonally pulled upwards from all sides of the tower body 2, which can share part of the vertical load borne by the tower body 2 and transfer the load to the foundation or other supporting structures through the steel cable 41. This can reduce the pressure on the tower body 2 structure and reduce the risk of the tower body 2 being crushed or deformed due to excessive vertical load;

[0029] When the main body of the tower 2 needs to support heavier equipment or the number of transmission line circuits increases, resulting in an increase in vertical load, the steel cable 41 can be used as an effective auxiliary bearing means to share the load with the main body of the tower 2, thereby improving the overall bearing capacity of the main body of the tower 2 and ensuring that the main body of the tower 2 can still operate stably under increased load.

[0030] It should be noted that the shape of the reinforcing rib 5 is diverse, and its cross-section is not limited to a certain style. Various cross-sectional shapes such as ellipse and irregular shape are also possible.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
