Problems solved by technology

However, exposed to the outdoors for a long time and subjected to different complex climates, especially in the northern and central and western alpine regions of China, the ice coating caused damage to the tower pole and the entire transmission line, especially the damage to the interior of the composite tower pole structure. Some safety accidents not only cause economic losses, but also pose a threat to people's lives and life safety.
The ice and snow disaster that occurred in 2008 caused huge losses to the economy due to the untimely deicing of tower poles
The first two methods cannot prevent icing, and cannot deicing in a timely and effective manner, which is extremely harmful to the tower
The third method is passive de-icing, which has limited anti-icing ability, and the coating is vulnerable to the impact of climate and reduces performance, requiring frequent maintenance
Some patents have released related technologies about fiber reinforced material tower poles. For example, patent CN201649767U has released a composite insulation tower for power grid transmission lines. At the same time, the weight and cost are effectively reduced; in the technical scheme of patent CN202039634U, the fiber grating temperature sensor installed in the composite material tower is used to connect with the external temperature measuring equipment to monitor the temperature of the tower shaft and the cross arm, but it cannot effectively Avoid temperature changes caused by the environment in severe cold areas
Neither solves the problem of anti-icing and de-icing of fiber-reinforced materials

Abstract

The invention discloses a fiber reinforced composite material tower pole with anti-icing and deicing functions. The fiber reinforced composite material tower pole with the anti-icing and deicing functions comprises a tower pole body; the tower pole body is sequentially composed of a insulating and heat-protective layer, a structure layer, a carbon fiber heating layer and a insulating protective layer from the inside to the outside; the carbon fiber heating layer utilizes carbon fiber as a heating element, the two ends of the carbon fiber heating layer are correspondingly connected with conductive electrodes, and the conductive electrodes are connected with a control switch device in the hollow cavity of the tower pole through guide wires. According to the fiber reinforced composite material tower pole with the anti-icing and deicing functions, anti-icing and deicing of the surface of the fiber reinforced composite material tower pole under the low-temperature freezing environment are realized, the effect of icing on the internal structure of composite material tower pole is avoided, mechanical properties and carrying capacity of the composite material tower pole are enhanced, the service life of the composite material tower pole is prolonged, and the fiber reinforced composite material tower pole can be used in cold weather and harsh environment area.

Description

technical field [0001] The invention relates to a composite material tower rod, in particular to a composite material tower rod capable of anti-icing and deicing in a low-temperature and easy-to-freeze environment. Background technique [0002] There are mainly several materials for transmission line towers at home and abroad: wood, reinforced concrete and steel structures. Wooden towers are prone to corrosion; steel structures are prone to rust and have poor insulation; concrete towers are heavy, and these shortcomings limit the development and application of traditional towers in remote mountainous areas or complex terrain. Due to its light weight, high strength, corrosion resistance, good designability, easy installation and maintenance, fiber reinforced composite tower rods overcome the shortcomings of traditional tower rods and improve the safety of transmission circuits to a certain extent And reliability, in recent years gradually received attention. However, expose...
