Technical Field
The invention belongs to the technical field of power transmission lines, and particularly relates to a steel pipe tower capable of preventing 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.
Disclosure of Invention
The invention aims to provide a steel pipe tower capable of preventing breeze vibration, which solves the problems that bolt connection is loosened or a connecting plate is damaged due to continuous and repeated breeze vibration of a rod piece of the conventional steel pipe tower, improves the structural safety of the steel pipe tower and prolongs the service life of the steel pipe tower.
In order to achieve the above object, the present invention provides a steel pipe tower for preventing a breeze vibration, including a steel pipe tower body and various rod members, 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 invention arranges the irregular spoilers on the steel tube tower rod piece, and adjusts the shape, the number and the size of the spoilers according to the size of the wind speed and the property of a wind field to disturb or prevent the vortex formed after the transverse wind bypasses the steel tube, thereby preventing the rod piece from generating breeze vibration. The invention is applied to the tin union-victory 1000 KV transmission line engineering for the first time, and obtains satisfactory results. Compared with the traditional treatment measures such as stay wires and the like, the invention has more convenient construction and more obvious effect, and radically prevents the occurrence of breeze vibration. Can be used in large scale in the construction and the established project. Particularly, the construction of the invention is more convenient and rapid for solving the problem of breeze vibration of the steel pipe tower structure which is put into operation, and the economic benefit is obvious.

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, in the embodiment of the invention, a plurality of irregular spoilers 5 are respectively welded on a tower body lower cross member 2, a horizontal partition surface rod member 3 and a leg V-surface rod member 4 of a steel pipe tower body 1, and are used for disturbing a vortex formed after breeze bypasses the rod members and preventing the rod members from breeze vibration. 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 number, size and specification of the spoilers of the invention can be varied according to the local wind speed.
