Description

Technical Field

[0001] This utility model relates to the field of power transmission tower technology, specifically to power transmission towers resistant to strong wind loads. Background Technology

[0002] In modern power transmission networks, transmission towers, as key facilities supporting transmission lines, are of paramount importance in terms of stability. However, in areas prone to strong winds, traditional transmission towers often suffer from insufficient wind resistance, tilting or even collapsing under strong winds, severely impacting the stability and reliability of power supply. The excessively high construction and maintenance costs also place enormous pressure on power companies. To address these issues, we propose a transmission tower design that can effectively withstand strong wind loads while reasonably controlling costs.

[0003] As disclosed in authorization announcement number CN106322335A, a power transmission tower includes a tower body, an electrical cabinet, a solar panel, a photosensitive switch, and a battery and LED warning light installed inside the electrical cabinet. The electrical cabinet is fixedly mounted on the tower body via a U-shaped hanging ring, and the solar panel is mounted on top of the electrical cabinet. The solar panel is connected to the battery for charging, and the battery is connected to the LED warning light for powering it. The photosensitive switch is installed outside the electrical cabinet and connected in series with the LED warning light to detect the ambient brightness and disconnect the circuit when the brightness is higher than a preset value, and connect the circuit when the brightness is lower than the preset value. This power transmission tower can achieve a nighttime warning function by connecting the battery to the LED warning light, but it does not address the structural improvement of the tower's stability and strength.

[0004] The purpose of this invention is to provide a transmission tower resistant to strong wind loads, in order to solve the problems mentioned in the background art, such as insufficient wind resistance and high construction and maintenance costs of traditional transmission towers. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A power transmission tower resistant to strong wind loads includes a foundation and auxiliary mechanisms. A mounting base is fixedly installed on the upper surface of the foundation. The power transmission tower body is fixedly installed on top of the mounting base. The auxiliary mechanisms are fixedly installed at both ends of the mounting base. Each auxiliary mechanism includes a fixing iron block, a threaded hole, and a steel wire rope. The fixing iron blocks are fixedly installed at both ends of the mounting base. A threaded hole is opened at the center of the upper part of each fixing iron block. A threaded rod is rotatably installed inside the threaded hole. A fixing block is fixedly connected to the top of the threaded rod. A pull ring one is fixedly installed above the fixing block. A steel wire rope is installed above the pull ring one. A pull ring two is fixedly connected to the other end of the steel wire rope away from the pull ring one. The pull ring two is fixedly installed on one side above the power transmission tower body.

[0007] Preferably, multiple sets of shock-absorbing springs are fixedly installed at the bottom of the mounting base, and a damper is fixedly installed inside each shock-absorbing spring.

[0008] Preferably, the bottom end of the shock-absorbing spring is fixedly connected to a concrete base, and the concrete base is located at the inner bottom end of the foundation surface.

[0009] Preferably, a counterweight ball is fixedly installed in the center of the top of the transmission tower body, a buffer rod is fixedly connected to the outside of the counterweight ball, and the other end of the buffer rod is fixedly connected to the inside of the transmission tower body.

[0010] Preferably, the transmission tower body adopts a triangular frame structure, and triangular reinforcing ribs are fixedly installed on the outside.

[0011] Preferably, the bottom cross-sectional dimension of the transmission tower body is increased, and the cross-sectional dimension gradually decreases upwards.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This transmission tower resistant to strong wind loads, through the auxiliary mechanism consisting of fixed iron blocks, threaded holes, and threaded rods, can flexibly adjust the installation angle and tension of the steel wire rope. When strong winds strike, the steel wire rope straightens and fixes the transmission tower body to the ground, thereby effectively dispersing the wind force, enhancing the tower's wind resistance stability, reducing the risk of tower tilting or collapse, and improving the stability of the device.

[0014] 2. This transmission tower resistant to strong wind loads increases the cross-sectional size at the bottom of the tower body and gradually decreases it upwards, allowing the bottom of the tower to withstand greater pressure and bending moment. As the height increases, the force on the upper structure gradually decreases. By reducing the cross-sectional size, the weight of the tower is reduced while ensuring strength, which improves structural strength, reduces cost, and thus improves the practicality of the device.

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A transmission tower resistant to strong wind loads includes a foundation surface 1 and auxiliary mechanisms 2. A mounting base 3 is fixedly installed on the upper surface of the foundation surface 1. The transmission tower body 4 is fixedly installed on top of the mounting base 3. Auxiliary mechanisms 2 are fixedly installed at both ends of the mounting base 3. The auxiliary mechanisms 2 include fixing iron blocks 201, threaded holes 202, and steel wire ropes 203. Fixing iron blocks 201 are fixedly installed at both ends of the mounting base 3. A threaded hole 202 is opened in the center of the upper part of the fixing iron block 201. A threaded rod is rotatably installed inside the threaded hole 202. A fixing block 204 is fixedly connected to the top of the threaded rod. A pull ring 205 is fixedly installed above the 204. A steel wire rope 203 is installed above the pull ring 205. A pull ring 206 is fixedly connected to the other end of the steel wire rope 203 away from the pull ring 205. The pull ring 206 is fixedly installed on one side above the transmission tower body 4. Through the cooperation of the fixing block 201, threaded hole 202 and threaded rod, the installation angle and tension of the steel wire rope 203 can be flexibly adjusted. When strong winds strike, the steel wire rope 203 straightens and fixes the transmission tower body 4 to the ground, thereby effectively dispersing the wind force, enhancing the wind resistance stability of the tower, and reducing the risk of tower tilting or collapse.

[0023] In this embodiment, preferably, multiple sets of shock-absorbing springs 5 ​​are fixedly installed at the bottom of the mounting base 3. A damper 6 is fixedly installed inside the shock-absorbing spring 5. When strong wind causes the tower to vibrate, the shock-absorbing spring 5 provides buffering, and the damper 6 consumes vibration energy, preventing the tower from being damaged due to excessive vibration and ensuring that the tower can still maintain stable operation under the continuous action of strong wind.

[0024] In this embodiment, preferably, the bottom end of the shock-absorbing spring 5 is fixedly connected to a concrete base 7, and the concrete base 7 is located at the bottom inside the foundation surface 1. By installing the transmission tower body 4 on the concrete base 7, a good base can be provided to prevent collapse.

[0025] In this embodiment, preferably, a counterweight ball 8 is fixedly installed in the center of the top of the transmission tower body 4, and a buffer rod 9 is fixedly connected to the outside of the counterweight ball 8. The other end of the buffer rod 9 is fixedly connected to the inside of the transmission tower body 4. When the tower body is subjected to external force, the counterweight ball 8 can generate a reverse force, enhance the stability of the tower, and thus improve the overall structural strength.

[0026] In this embodiment, preferably, the transmission tower body 4 adopts a triangular frame structure, and triangular reinforcing ribs 10 are fixedly installed on the outside. The triangular reinforcing ribs 10 fixed on the outside of the transmission tower body 4 prevent structural damage.

[0027] In this embodiment, preferably, the bottom cross-sectional dimension of the transmission tower body 4 is increased and gradually decreases upward. This allows the bottom of the tower to withstand greater pressure and bending moment. As the height increases, the force borne by the upper structure gradually decreases. By reducing the cross-sectional dimension, the weight of the tower is reduced while ensuring strength, which improves structural strength and reduces cost.

[0028] In this embodiment, the transmission tower resistant to strong wind loads, through the auxiliary mechanism 2, can flexibly adjust the installation angle and tension of the steel wire rope 203 by cooperating with the fixed iron block 201, threaded hole 202, and threaded rod. When strong winds strike, the steel wire rope 203 straightens and fixes the transmission tower body 4 to the ground, thereby effectively dispersing the wind force, enhancing the tower's wind resistance stability, and reducing the risk of tower tilting or collapse. By increasing the cross-sectional size at the bottom of the transmission tower body 4 and gradually decreasing the cross-sectional size upwards, the bottom of the tower can withstand greater pressure and bending moment. As the height increases, the force borne by the upper structure gradually decreases. By reducing the cross-sectional size, the weight of the tower is reduced while ensuring strength, which improves structural strength, reduces cost, and thus improves the practicality of the device.
