Technical Field
The utility model belongs to the technical field of transmission line, specifically be a prevent steel-pipe tower of breeze vibration.
Background
The ultra-high voltage transmission line engineering double-loop iron tower or the large-span (river-crossing) iron tower adopts a steel pipe tower structure. And some of the rod pieces with larger slenderness ratio (more than 110) comprise tower body lower cross members, horizontal partition surface rod pieces and leg V-shaped surface rod pieces, and are easy to generate transverse vibration perpendicular to the wind direction when the wind speed is low, which is called breeze vibration in engineering. The continuous and repeated breeze vibration can cause the bolt connection of the rod piece to be loose or the fatigue failure of the connecting plate, thereby causing the potential safety hazard of the structure and reducing the service life.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a prevent steel-pipe tower of breeze vibration solves current steel-pipe tower member and continuously relapses the breeze vibration and leads to bolted connection not hard up or connecting plate fatigue failure, improves steel-pipe tower structure security, increase of service life.
In order to achieve the above object, the utility model provides a prevent steel-pipe tower of breeze vibration, including steel-pipe tower body, various member, its characterized in that: irregular spoilers are arranged on various rod pieces and used for disturbing vortexes formed by breezes bypassing the rod pieces.
Furthermore, irregular turbulence holes are formed in the turbulence plate.
Furthermore, the wind power generation device also comprises a clamp connected with the irregular spoilers, and the spoilers are fixed on the rod pieces through the clamp, so that the shape, the number and the size of the spoilers can be conveniently adjusted according to the size of the wind speed and the property of a wind field.
Further, the steel pipe member protective device also comprises a rubber pad connected to the inner surface of the clamp, and the rubber pad prevents the inner surface of the clamp from damaging the protective layer of the steel pipe member.
Furthermore, the installation distance of the spoilers on the same rod piece is controlled to be 1000-2000 mm, and the spoilers are adjusted according to the vibration amplitude of the rod piece.
Furthermore, the size of the clamp is smaller than that of the spoiler, so that the weight is reduced, and the spoiler effect is improved.
Furthermore, the diameter of the turbulent flow hole is 12-20 mm.
The utility model discloses set up anomalous spoiler on steel-pipe tower member, adjust shape, quantity and the size of spoiler according to the size of wind speed and the nature of wind field, disturb or prevent the swirl that forms behind the steel pipe by the crosswind to prevent the emergence of the breeze vibration of member. The utility model discloses obtain experimental application in tin ally-victory 1000 kilovolts transmission line engineering for the first time, obtained satisfactory result. Compare with traditional treatment measures such as acting as go-between, the utility model discloses the construction is more convenient, and the effect is more obvious, has prevented the emergence of breeze vibration from the root. Can be used in large scale in the construction and the established project. Especially to the gentle breeze vibration of the steel-pipe tower structure of solving the operation, the utility model discloses a construction convenient and fast more, economic benefits is showing.

FIG. 2 is a schematic structural diagram of a second embodiment;
FIG. 3 is a schematic view showing the connection position relationship between the spoiler and the clip;
fig. 4 is a schematic view of a spoiler structure.
The tower comprises a steel pipe tower body 1, a tower body lower cross material 2, a horizontal partition surface rod piece 3, a leg V-surface rod piece 4, a spoiler 5, a clamp 6, a rubber pad 7, various rod pieces 8, bolts 9, bolt holes 10 and a turbulent flow hole 11.
Detailed Description
Referring to fig. 1, the present invention is embodied by welding a plurality of irregular spoilers 5 to the tower lower cross member 2, the horizontal partition member 3 and the leg V-shaped member 4, respectively, for disturbing the vortex formed by the breeze bypassing the members and preventing the occurrence of breeze vibration of the members. The form is suitable for newly-built steel tube tower structures.
Referring to fig. 2, for the built project, a jig is used for installation. Namely, the split type clamp 6 is connected with the irregular spoiler 5, the thickness of the clamp is 3-5mm, and the size is determined according to the specific rod diameter. The spoiler is fixed on the rod piece through the clamp, so that the spoiler is convenient to mount, dismount and adjust, and the shape, the number and the size of the spoiler can be conveniently adjusted according to the size of the wind speed and the property of a wind field. The thickness of the flow disturbing plate is 3-5mm, the height is 50-120mm, and the length is 100-300 mm. The inner surface of the clamp is provided with a rubber pad 7 to prevent the inner surface of the clamp from damaging the zinc coating of the rod piece. The mounting distance of the spoilers on the same rod piece is controlled between 1000mm and 2000mm, and the spoilers are adjusted according to the vibration amplitude of the rod piece. This form can also be used to build new steel tube tower structures.
Referring to fig. 3, the clamp is provided with a bolt hole with a diameter of 22mm for passing through the bolt 9 of M20 to fix the clamp. The height dimension of the clamp 6 is smaller than that of the spoiler 5, so that the weight is reduced, and the spoiler effect is improved.
Referring to fig. 4, the spoiler is provided with irregular spoiler holes 11, the diameter of each spoiler hole is 12-20mm, and the positions of the spoiler holes can be irregularly arranged.
The utility model discloses quantity, size and the specification of well spoiler can change according to local wind speed.
