Description

Technical Field

[0001] This utility model relates to the field of anti-dancing tower technology for coastal power transmission lines, specifically an anti-dancing tower for coastal power transmission lines. Background Technology

[0002] Coastal power transmission line anti-galling towers are devices used to prevent power transmission lines from galloping due to sea breezes.

[0003] For example, a transmission line anti-galling device with authorization announcement number "CN214314467U" includes a hollow cylinder. The bottom of the hollow cylinder is a spherical arc structure with an outward convex shape. A sphere is placed inside the hollow cylinder, and a connecting rod is placed at the top of the hollow cylinder. The connecting rod is detachably connected to a spacer bar. The anti-galling device is built into the spacer bar of the transmission line to avoid strong corona noise caused by excessive local electric field distortion. The weight inertia of the sphere can be flexibly adjusted, which is beneficial to the damping effect of the anti-galling. However, when the transmission line anti-galling device is used, it will move with the wind source when blown by strong winds. Its own gravity will make it return to its original position. At this time, an inertia will be formed, which will increase the galling of the transmission line anti-galling device. It cannot form a relative force with the wind source, so the transmission line anti-galling device cannot slow down the galling of the transmission line. Therefore, a transmission line anti-galling tower is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that anti-galling devices for power transmission lines cannot slow down the galloping of power transmission lines, and to propose an anti-galling tower for coastal power transmission lines.

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

[0006] Design a coastal power transmission line anti-surge tower, including a base and a second support. The top of the base is fixedly connected to the bottom of the second support. An anti-surge structure is connected to the top of the second support. Horizontal plates are connected to the bottom of the left and right sides of the anti-surge structure, and a control structure is connected to the bottom of the horizontal plates.

[0007] Preferably, the anti-fighting structure includes a first support and a square plate. The bottom of the first support is fixedly connected to the top of the second support. The upper and lower sides of the inner wall of the first support are respectively fixedly connected to the outer sides of a plurality of square plates. A mass damper is attached to the top of the lower square plate. A steel wire rope is connected through the top of the mass damper. The top of the steel wire rope is connected through the inner wall of the upper square plate.

[0008] Preferably, a first bolt is threaded to the lower outer wall of the mass damper, and the bottom of the outer wall of the first bolt is threaded to the inner wall of the lower square plate.

[0009] Preferably, the bottom of the left and right sides of the first bracket are fixedly connected to the inner sides of the two horizontal plates, respectively.

[0010] Preferably, the control structure includes an insulator and a first arc plate. The top of the insulator is fixedly connected to the bottom of the horizontal plate, and the bottom of the insulator is fixedly connected to the top of the first arc plate. A second arc plate is attached to the bottom of the first arc plate. Second bolts are threadedly connected to the left and right sides of the top of the first arc plate, and the bottom of the outer wall of the second bolt is threadedly connected to the top of the second arc plate.

[0011] Preferably, the base has four support legs fixedly attached to its bottom corners.

[0012] The present invention proposes an anti-galling tower for coastal power transmission lines, which has the following advantages: the mass damper in the anti-galling structure is controlled by a computer, which can increase the overall mass of the mass damper. When the mass damper increases, it will tighten the steel wire rope (which is a carbon steel rope) at the top, and at the same time apply a force opposite to the wind force to the mass damper. This will create a vibration tuning, which will reduce the vibration of the entire tower body, thereby achieving anti-galling of the power lines installed on the outer wall of the tower. It is impossible to completely stop the power line from galling, but the galling range can be greatly reduced, thus achieving the goal of slowing down the galling of the power transmission line.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] Please see Figure 1-4 In this embodiment, a coastal transmission line anti-surge tower includes a base 1 and a second support 4. The top of the base 1 is fixedly connected to the bottom of the second support 4. An anti-surge structure 2 is connected to the top of the second support 4. Horizontal plates 6 are connected to the bottom of the left and right sides of the anti-surge structure 2, and a control structure 3 is connected to the bottom of the horizontal plates 6.

[0021] The anti-fighting structure 2 includes a first support 201 and a square plate 202. The bottom of the first support 201 is fixedly connected to the top of the second support 4. The upper and lower sides of the inner wall of the first support 201 are fixedly connected to the outer sides of multiple square plates 202 respectively. A mass damper 203 is attached to the top of the lower square plate 202. The model of the mass damper 203 is selected according to the usage requirements. A steel wire rope 204 is connected through the top of the mass damper 203. The steel wire rope 204 is made of carbon steel rope. The top of the steel wire rope 204 is connected through the inner wall of the upper square plate 202. A first bolt 205 is threadedly connected to the lower outer wall of the mass damper 203. The bottom of the outer wall of the first bolt 205 is threadedly connected to the inner wall of the lower square plate 202. The first bolt 205 plays a fixing role for the mass damper 203 and the lower square plate 202. The bottom of the left and right sides of the first support 201 are fixedly connected to the inner sides of two horizontal plates 6 respectively.

[0022] The mass damper 203 in the anti-galling structure 2 is controlled by a computer. The overall mass of the mass damper 203 can be increased. When the mass damper 203 increases in mass, it will tighten the top wire rope 204 (the wire rope 204 is a carbon steel rope). At the same time, it will apply a force opposite to the wind force to the mass damper 203. This will form a vibration tuning, which will reduce the vibration of the entire tower body, thereby achieving anti-galling of the power lines installed on the outer wall of the tower. It is impossible to completely stop the power line galloping, but the galloping range can be greatly reduced. This realizes the function of the power line anti-galling device to reduce the galloping of the power line.

[0023] The control structure 3 includes an insulator 301 and a first arc plate 302. The top of the insulator 301 is fixedly connected to the bottom of the horizontal plate 6. The insulator 301 plays an important role in mechanical support and can withstand the weight of the conductor, wind force and temperature changes, etc., to ensure the normal operation of the conductor and the stability of power transmission. The bottom of the insulator 301 is fixedly connected to the top of the first arc plate 302. The bottom of the first arc plate 302 is attached to a second arc plate 303. The top left and right sides of the first arc plate 302 are respectively threaded with second bolts 304. The second bolts 304 fix the first arc plate 302 and the second arc plate 303. The bottom of the outer wall of the second bolt 304 is threadedly connected to the top of the second arc plate 303. The four corners of the bottom of the base 1 are respectively fixed with support legs 5.

[0024] Working principle:

[0025] Erection of anti-scaling towers for power transmission lines:

[0026] Fix the bottom of the outrigger 5 to the designated position along the coast (either by pre-embedding or welding). Then, attach the bottom of the mass damper 203 to the top of the lower square plate 202. Next, thread the first bolt 205 through the mass damper 203 from top to bottom and connect it to the inner wall of the lower square plate 202. Then, thread the wire rope 204 through the top round opening of the mass damper 203 and weld it in place. Then, thread the other end of the wire rope 204 through the inner wall of the upper plate 202 and weld it in place, thus fixing the mass damper 203. Rotate the second bolt 304 upwards to disengage the lower outer wall of the second bolt 304 from the second arc plate 303. Then, pull the second arc plate 303 downwards to disengage it. Then, attach the outer wall of the wire to the inner wall of the first arc plate 302. Next, put the second arc plate 303 back in and rotate the second bolt 304 downwards to connect it to the second arc plate 303, thus fixing the wire.

[0027] Use of anti-dancing towers on power transmission lines:

[0028] When the entire tower is blown by the sea breeze, the mass damper 203, which is controlled by a computer, can increase its overall mass. When the mass damper 203 increases its mass, it will tighten the steel wire rope 204 (which is a carbon steel rope) at the top and apply a force opposite to the wind force to the mass damper 203. This will create a vibration tuning effect, which will reduce the vibration of the entire tower and thus prevent the power lines installed on the outer wall of the tower from galloping. It is impossible to completely stop the power lines from galloping, but the range of galloping can be greatly reduced.

[0029] Example 2:

[0030] Please see Figure 1-4 In this embodiment, a coastal power transmission line anti-dancing tower also includes a straight plate 7, the two ends of which are fixedly connected to the inner sides of two support legs 5 respectively.

[0031] Working principle:

[0032] The straight plate 7 acts as a support for the outrigger 5, preventing the outrigger 5 from cracking and deforming outward due to prolonged exposure to gravity, while also ensuring the integrity of the two outriggers 5.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
