Description

High-strength composite material telegraph pole

Technical Field

The invention belongs to the technical field of telegraph poles, and particularly relates to a high-strength composite telegraph pole.

Background

As is well known, a power pole plays an important role in national economy and people's life, and mainly comprises a power pole, a communication pole, a utility pole and the like, and a power transmission line is an economic life line of a country. The transmission lines interconnecting the large load centers with the remote power generation sources are critical to redistributing power on demand. It is known to form power transmission poles from treated wood poles. However, it has been found that the chemicals used to treat wood poles contain carcinogens. Environmental and economic problems arising from the special handling of treated wood poles have led to the search for alternatives to wood. Concrete and steel are also used to form utility poles. However, the weight of these materials makes transportation and installation cost prohibitive. In addition, steel is highly conductive, while concrete structures expand and contract with temperature resulting in longitudinal cracks. Erosion resistance is another common concern when using utility poles. The ground on which the utility pole is placed and the surrounding environment can erode the utility pole, reducing the length of the pole and shortening the life of the utility pole.

Composite poles are highly desirable because they are lightweight, resistant to erosion, and non-conductive. In addition, composite materials are often produced using environmentally friendly methods, particularly compared to steel poles. The existing complete assembly mode of the composite material tower is mainly connected with the prepared rod body in a flange tool mode. However, the whole composite material pole assembled by the flange tool not only increases the dead weight and transportation cost of the telegraph pole, but also adds complicated procedures for the assembly work of the telegraph pole, has an abnormally complex structure and is not changed in installation, and can not solve the related problems of material characteristics and structural design coordination, such as insufficient compression rigidity, inconsistent deformation and the like.

This wire pole is applicable to the region of easily sending out the typhoon in guangdong coast, through the clamp cooperation of adding elastic support and body of rod outside in the body of rod inside to support the body of rod, avoid the wire pole body of rod when bearing great wind-force, because the atress inequality causes the cracked condition of the body of rod to take place, thereby improve the life of wire pole.

Disclosure of Invention

In order to make up for the defects of the prior art, the invention provides the high-strength composite material telegraph pole which is simple in structure and convenient to operate, and the pole body is supported by adding the elastic support inside the pole body to be matched with the clamp outside the pole body, so that the situation that the pole body is broken due to uneven stress when the pole body of the telegraph pole bears large wind power is avoided.

The technical scheme adopted by the invention for solving the technical problems is as follows: a high-strength composite material telegraph pole comprises a pole body, wherein the pole body is formed by combining and clamping two half poles, a group of hoops are distributed on the pole body at equal intervals from top to bottom, and a group of elastic supports are arranged in the pole body at equal intervals; the half-rods are made of elastic materials; the elastic supports are provided with at least four. When the device works, two half rods are convenient to convey and are conveyed to a designated place to be installed, the two half rods are firstly clamped and combined, then the half rods are fixed by utilizing the clamps, a group of elastic supports are symmetrically adhered inside the half rods, when strong wind occurs, the rod body is influenced by wind power, the middle part of the rod body is sunken inwards, so that a gap is generated between the inner wall of the clamp and the outer wall of the rod body, the clamps slide downwards under the action of self gravity, so that the space between the clamps is changed, simultaneously, due to the elastic support inside, the middle part of the rod body is greatly stressed and deformed, the large supporting force of the elastic support is large in deformation, the clamps can be clamped again when encountering a small deformation area after sliding downwards slightly, the clamps are concentrated in the middle part of the rod body, the large supporting force of the elastic support is large in deformation, so that the local strength of the middle part of the rod, so that the rod body cannot be broken off; the wind power generation system is characterized in that a strong wind and a typhoon are frequently encountered in coastal areas in Guangdong, and the middle of the telegraph pole is broken due to wind influence and uneven stress, so that unpredictable damage is caused to life and property safety of people; this technical scheme passes through the elastic support cooperation that clamp and inside set up, can strengthen the bulk strength of the body of rod on the one hand, avoids the body of rod to meet strong wind rupture, and the clamp that on the other hand can utilize the elastic action that elastic support produced will move down is again pushed back initial position, has prolonged the life of the body of rod.
