Description

Technical Field

[0001] The utility model belongs to the technical field of transmission line protection devices, and particularly relates to a device for suppressing the micro-vibration of a high-voltage transmission tower. Background Art

[0002] Steel pipe towers are widely used in UHV transmission projects. They are composed of many steel pipe components. When the wind flows over the steel pipe components, vortices alternately shed from both sides of the cylinder. Each pair of vortices has lift forces in opposite directions, jointly constituting a pulsating lift force perpendicular to the flow direction. At the same time, the generation and release of vortices also generate a pulsating drag force in the flow direction of the column. When the wind speed is appropriate, vortex-induced vibration will occur, affecting the structural safety. To avoid this situation, vibration suppression devices are currently installed on the steel pipe components of transmission towers.

[0003] Although there are various current vibration suppression devices, there are still some problems. For example, most current vibration suppression devices form a vortex-breaking effect by setting sleeves on the steel pipe components and using the holes on the sleeves. However, most current sleeves adopt a split connection structure. When installing, it needs to be fixed on the steel pipe component through components such as screws. However, multiple sleeves often need to be set on one steel pipe component, and each sleeve also needs to be connected by a combination of multiple screws. This makes it time-consuming and labor-intensive to install and lock the sleeves. Moreover, due to the inevitable high-altitude operation during installation and the small size of the screws, the screws are likely to fall during installation, posing a great safety hazard.

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0025] An embodiment of the present utility model provides a high-voltage transmission tower micro-vibration suppression device, as Figures 1-5 shown, including: a vibration suppression tube 1 and a locking assembly 2;

[0026] The locking assembly 2 is connected to the center of the vibration suppression tube 1, and the vibration suppression tube 1 is connected and locked to the steel pipe member of the high-voltage transmission tower through the locking assembly 2;

[0027] The locking component 2 includes a fixed seat 21, a connecting buckle 22, a limiting seat 23, a sliding groove 24, a clamping block 25 and a locking plate 26. The fixed seat 21 is fixed at the center of the outer side of the vibration damping tube 1. The connecting buckle 22 is connected between two adjacent fixed seats 21 up and down. The limiting seat 23 is arranged on one side of the fixed seat 21. The sliding groove 24 is arranged in the limiting seat 23 in a concave manner, and one end of the sliding groove 24 penetrates to one side of the limiting seat 23. The clamping block 25 is fixed at the other end of the sliding groove 24. The locking plate 26 is fixed on the side wall of the connecting buckle 22, and the locking plate 26 is slidably clamped in the sliding groove 24 and abuts against the clamping block 25, and the locking plate 26 is in an L-shaped structure.

[0028] It should be noted that since most of the existing vibration damping devices form a broken vortex effect through holes on the sleeve provided on the steel pipe member, but currently most of the sleeves adopt a split connection structure, when installing, it needs to be fixed on the steel pipe member through components such as screws. However, multiple sleeves often need to be provided on one steel pipe member, and each sleeve also needs to be connected by a combination of multiple screws. This makes it take a lot of time and manpower to install and lock the sleeves during installation. And because high-altitude operations are inevitable during installation, and the screws are small in volume, so it is easy to occur the phenomenon of screw dropping during installation, there are great safety hazards. To solve this problem, the locking component 2 is set in this solution. The connecting buckle 22 in the locking component 2 locks the two fixed seats 21 up and down, so that the two vibration damping tubes 1 up and down can be quickly locked on the steel pipe member of the high-voltage transmission tower and form an integral structure. The vibration damping tube 1 breaks the wind direction on the surface of the steel pipe member, horizontally blocks the vortex formed by the gentle breeze airflow on the steel pipe member, and thus effectively suppresses the gentle breeze vibration of the steel pipe member for vibration damping. And during installation and docking, the locking plate 26 slides in the sliding groove 24 and abuts against the clamping block 25, thus forming a locking structure, and at the same time, by rotating the connecting buckle 22, the two fixed seats 21 up and down can be quickly locked. It is simple and efficient, avoiding the need to use components such as screws to assemble and install the vibration damping tube 1, effectively saving manpower and material resources, and also greatly improving the work efficiency.

[0029] Specifically, in this embodiment, this solution mainly includes a vibration damping tube 1, a locking component 2 and a clamping plate 3. The clamping plate 3 arranged inside the vibration damping tube 1 abuts against the steel pipe member of the high-voltage transmission tower, and the connecting buckle 22 in the locking component 2 locks the two fixed seats 21 up and down. When connecting, first snap the locking plate 26 on one side of the sliding groove 24, and then rotate the connecting buckle 22 until the locking plate 26 rotates to the clamping block 25 and abuts against the clamping block 25. And during the rotation, the abutting plate 27 slides and abuts against the limiting seat 23, and pushes the two limiting seats 23 up and down to move, so that the clamping block 25 and the locking plate 26 can firmly abut and lock.

[0030] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, the locking assembly 2 further includes an abutting plate 27, which is fixed at the axial center of the side wall of the connecting buckle 22 and is located on the same side as the locking plate 26. An arc-shaped groove is provided at the inner center of the limiting seat 23, and the abutting plate 27 is slidably abutted in the arc-shaped grooves of two adjacent upper and lower limiting seats 23.

[0031] In this embodiment, by rotating the abutting plate 27, the two adjacent upper and lower fixing seats 21 can be separated from each other, so that the block 25 and the locking plate 26 can be firmly locked, and then the two upper and lower fixing seats 21 can be firmly locked through the connecting buckle 22.

[0032] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, a limiting ring 28 is provided at the edge of one side of the connecting buckle 22 close to the locking plate 26. The limiting ring 28 has an arc-shaped structure and is symmetrically arranged up and down in two. A notch is provided between the limiting seat 23 and the fixing seat 21, and the limiting ring 28 is slidably clamped in the notch.

[0033] In this embodiment, the connecting buckle 22 is limited by the limiting ring 28 to prevent it from slipping off.

[0034] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, indicating bumps 29 are provided on the outer walls of the fixing seat 21 and the connecting buckle 22.

[0035] In this embodiment, the rotation position of the connecting buckle 22 is indicated by the indicating bumps 29, which is more convenient for the staff to assemble the two upper and lower vibration damping pipes 1.

[0036] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, a clamping plate 3 is provided at the inner center of the vibration damping pipe 1, and a plurality of damping rods 4 are provided between the clamping plate 3 and the vibration damping pipe 1, and a spring 5 is sleeved on the damping rod 4. One end of the spring 5 abuts against the vibration damping pipe 1, and the other end abuts against the clamping plate 3.

[0037] In this embodiment, the clamping plate 3 abuts against the steel pipe member of the high-voltage transmission tower, and when abutting, the clamping plate 3 and the vibration damping pipe 1 can be firmly locked on the steel pipe member by the elastic force of the spring 5, and the vibration of the vibration damping pipe 1 itself is reduced by providing the damping rods 4.

[0038] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, the clamping plate 3 has an arc-shaped structure, and anti-slip lines are provided on the inner side of the clamping plate 3.

[0039] In this embodiment, the anti-slip lines are provided to prevent the clamping plate 3 from sliding on the steel pipe member of the high-voltage transmission tower.

[0040] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, the vibration suppression pipe 1 has an arc-shaped structure, and fragmentation vortex holes 6 are formed through the vibration suppression pipe 1, and a plurality of fragmentation vortex holes 6 are provided.

[0041] In this embodiment, the vibration suppression pipe 1 has the function of fragmenting vortices through the fragmentation vortex holes 6, suppressing the vortices formed by the gentle breeze airflow on the steel pipe of the transmission tower.

[0042] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, the outer wall of the abutting plate 27 and the outer wall of the arc-shaped groove at the center of the limiting seat 23 are both roughened.

[0043] In this embodiment, the friction force between the limiting seat 23 and the abutting plate 27 is increased through the roughening treatment, avoiding the rotation between the two due to insufficient friction force, resulting in the separation of the upper and lower fixing seats 21, and further resulting in the detachment of the vibration suppression pipe 1.
