Description

Wind-proof and vibration-reducing device for transmission line iron tower

technical field

The invention relates to the technical field of iron tower protection devices, in particular to a windproof and vibration-reducing device for an iron tower of a power transmission line.

Background technique

As the support point of the transmission line, the iron tower plays a very important role in the construction of electric power. However, the transmission tower will vibrate violently under severe weather conditions (strong wind, heavy rain, snowstorm, earthquake, etc.), and even cause the tower to deform or break. In coastal areas, considering the frequent typhoons and high wind intensity, when strong winds strike, the iron tower is likely to collapse under the action of the wind. Once the tower collapses, it will cause large-scale power outages and take a long time to repair the fault. Not only will it produce direct economic losses, but it will also seriously threaten the safe and stable operation of the power grid.

The traditional wind protection measures mainly improve the wind resistance performance of the tower by strengthening the tower base or increasing the size of the tower, but this will result in expensive engineering costs.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Please refer to Fig. 1, Fig. 2 and Fig. 3, the preferred embodiment of the present invention provides a kind of transmission line iron tower windproof vibration damping device, comprises mass block 1, suspension wire rope 2, hydraulic damper 3, wind speed sensor 4 and control computer 5 The quality block 1 is suspended on the iron tower 6 through the suspension wire rope 2, the two ends of the hydraulic damper 3 are respectively connected with the mass block 1 and the tower body 6, the wind speed sensor 4 is installed on the iron tower 6, and the hydraulic damper 3 and the wind speed sensor 4 are both Connect with control computer 5. Wherein, as a preferred embodiment, the mass block 1 is a steel ball, the steel ball has high density and high quality, and the spherical mass block 1 is particularly suitable for symmetrical and uniform arrangement of other connected parts; the suspension steel wire rope 2 is 2, and 2 The suspension wire rope 2 is evenly and symmetrically connected around the mass block 1; the hydraulic dampers 3 are divided into four groups, which are respectively connected to the top, bottom and corresponding sides of the mass block 1. This arrangement makes the four groups of hydraulic dampers 3 evenly Distributed on the top, bottom, left, and right of the mass block 1, it can realize the uniform effect of the hydraulic damper 3 on the mass block 1 in all directions; the mass block 1 is suspended at a height above 2/3 of the iron tower; the control computer 5 can be installed on the iron tower 6 , can also be installed on the ground, in this preferred embodiment, the control computer 5 is installed on the ground.

During implementation, when the wind speed sensor 4 installed on the iron tower 6 detects that the wind condition tends to cause the iron tower to tilt, shake, etc., the control computer 5 drives the hydraulic damper 3 to regulate the mass block 1 to tilt in the opposite direction of the wind Or shaking, so that the swing direction of the mass block 1 is opposite to that of the iron tower 6, so as to reduce or eliminate the inclination or vibration of the iron tower 6; when the wind speed sensor 4 detects that the wind condition is good, the iron tower 6 will not tilt or shake. The control computer 5 locks the hydraulic damper 3 so that the mass block 1 will not swing. Through this setting, the protection of the iron tower 6 under the action of strong wind can be realized, the vibration amplitude of the iron tower 6 can be reduced, and serious electric accidents such as the collapse of the tower can be avoided.
