[0002] Cement poles, also known as concrete poles or concrete utility poles, are structural elements widely used in power transmission and distribution systems. They are mainly used to support power lines and cables, transmitting electricity from power stations to users. Cement poles are mainly made of concrete and may contain steel bars or prestressed steel wires to enhance their structural strength. The manufacturing process usually adopts a centrifugal molding process, pouring concrete into a rotating mold to ensure uniform distribution and form a hollow pole structure, which helps to reduce weight and increase strength. Applications of cement poles include: power transmission, used in high-voltage transmission lines to support high-voltage power lines; distribution system, used in medium and low voltage distribution networks to support distribution lines; street lighting, as a support structure for street lamps; communication lines, supporting telephone lines, network cables, etc.

[0003] Windproof compression cement poles are commonly used in power transmission, communication networks, lighting facilities, etc. They need to have certain strength and stability to resist wind and other external forces. The basic structure of a simple windproof compression cement pole is as follows: structural composition: pole body, the main part of the cement pole, usually cylindrical or with a certain taper to improve bending resistance, made of concrete, sometimes with steel bars or steel fibers to enhance compression and bending resistance; foundation, the support part of the cement pole, usually buried underground to ensure stability and wind resistance, foundation design needs to consider soil conditions, pole height, and expected wind pressure; top structure, used to install power lines, communication cables, or lighting equipment, designed to have sufficient strength and appropriate structure to withstand the weight of the equipment and wind force; reinforcing bars, steel bars or steel strips added at certain parts of the pole body to improve bending and torsional resistance; guy wires, providing lateral support to enhance the wind resistance of the cement pole or tower.

[0010] The utility model further sets up, the base is connected with a plurality of support columns located in the periphery of screw thread variable diameter rod between stabilizing box.

[0011] Through the above technical scheme, when the screw thread variable diameter rod swings, the support column in the swing direction plays a supporting role, at the same time, the support column in the opposite direction plays a pulling role, through this support and pull, the stability of the device is improved.

[0012] The utility model further sets up, the screw thread variable diameter rod and each support column are commonly provided with a plurality of limiting plates.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A type of windproof and pressure-resistant cement pole, such as Figures 1-4 As shown, the device includes a base 1, with a threaded reducing rod 4 mounted on the top of the base 1. The middle dimension of the threaded reducing rod 4 is smaller than the dimensions at both ends. The outer surface of the threaded reducing rod 4 is threaded. A base plate 5 is fixed to the bottom of the base 1, and several positioning holes 7 are provided on the base plate 5. When strong winds blow over the threaded reducing rod 4, vortices will appear behind the cement column due to the Karman vortex street phenomenon, causing the cement column to vibrate and potentially leading to an accident. However, the spiral appearance of the threaded reducing rod 4 can reduce the generation of turbines. In addition, the structure of being thinner in the middle and thicker at both ends can not only reduce wind resistance but also make the intensity of the vortex behind the threaded reducing rod 4 different, preventing the vortex from resonating and thus enhancing the stability of the device.

[0028] A stabilizing box 3 is installed at the top of the threaded reducing rod 4, and a steel cable 12 is connected downward to the top surface of the inside of the stabilizing box 3.

A telescopic rod 13 is connected between the bottom edge of the damping ring 11 and the bottom edge of the inside of the stabilizing box 3. When the threaded reducing rod 4 swings, the damping ball 10 connected to the stabilizing box 3 by the steel cable 12 and the damping ring 11 remains stationary due to inertia. At this time, relative to the threaded reducing rod 4, the damping ball 10 is moving in the opposite direction of the swing and transmits the force to the entire device through the telescopic rod 13, thereby reducing the swing frequency and swing intensity of the threaded reducing rod 4 and enhancing the stability of the device.

[0029] Several support columns 8 located around the threaded variable diameter rod 4 are connected between the base 1 and the stabilizing box 3. When the threaded variable diameter rod 4 swings, the support columns 8 in the swing direction play a supporting role, while the support columns 8 in the opposite direction play a pulling role.

When the threaded reducing rod 4 and the support column 8 swing at the same time, the relative distance between them changes due to the bending of the threaded reducing rod 4 and the support column 8. At this time, the limiting plates 9 are used to determine the relative distance between the threaded reducing rod 4 and the support column 8, thereby slowing down the swing of the threaded reducing rod 4.

[0031] The base 1 is connected with the base plate 5 through several reinforcing ribs 6, which are mainly used to strengthen the connection between the base 1 and the base plate 5, and also support the device at various angles, so as to improve the stability of the device.
