Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transmission towers, and in particular to a self-resetting reinforcement device for a diaphragm of a transmission tower and a working method thereof. Background Art
[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.
[0003] Transmission towers are tall structures with a large height-to-width ratio, making them particularly sensitive to wind and often prone to collapse. High-voltage transmission lines are critical lifeline projects; a collapse can disrupt power supply on a large scale, causing significant damage to economic development, life, and property. In existing high-voltage transmission lines, diaphragms are crucial for increasing the rigidity of transmission towers. Existing diaphragm reinforcement materials are slender and often lack energy-dissipating devices, making them susceptible to compression, deformation, and instability in strong winds. Furthermore, the diaphragms of some older transmission towers are severely corroded and require maintenance.
[0004] In order to ensure the normal operation and safe transmission of high-voltage transmission lines and improve the wind resistance of high-voltage transmission lines, strengthening and renovating the existing towers is an economical and effective method to avoid the adverse power supply and economic effects brought about by line reconstruction.
[0005] The existing transmission tower diaphragm reinforcement mainly uses clamps, bolts or welding to add auxiliary main materials to constrain the diaphragm main materials to reduce the deformation of the original structure. The main problems are:
[0006] When using traditional clamps for connection, the secondary main material cannot be closely attached to the original main material, and the reinforcement effect is relatively general;
[0007] When using traditional welding methods for connection, due to the stress state of the tower itself, welding will generate high temperature effects on the main components, causing the steel in the welding area to deform, thereby changing the stress state and increasing the brittleness of the main material, ultimately affecting the original structure and affecting the reinforcement effect;
[0008] The traditional bolt connection requires drilling holes in the existing tower, and the operation is done at high altitude, which may cause inaccurate drilling and large hole expansion, greatly affecting the reinforcement effect.
[0009] In addition, all the above reinforcement methods have no energy-dissipating effect, and the structure is prone to large and irreversible deformation when subjected to large forces. Summary of the Invention

[0030] The beneficial effects of the present invention are as follows:
[0031] 1) The present invention provides a reinforcement device, including an edge node component fixed to the main material of the transmission tower, the edge node components are connected by an energy-absorbing component, the energy-absorbing component includes a first connecting member, and a second connecting member is respectively provided on both sides of the edge node component. The first connecting member and the second connecting member are both provided with an energy-absorbing reset component. The whole is subjected to force together with the main material of the transmission tower. At the same time, when the main material of the transmission tower is subjected to force, the flexible member in the energy-absorbing component can be deformed and then consume energy. The elastic member in the energy-absorbing reset component can perform telescopic movement along its axial direction to consume energy. After the energy consumption is completed, the elastic member can be reset. In this way, when the transmission tower is subjected to lateral force, it can effectively consume energy and reinforce the transverse diaphragm, thereby avoiding the transmission tower from buckling and instability due to the lateral force.
[0032] 2) In the present invention, a clamping member is provided on the energy dissipation reset component, which clamps the energy dissipation reset component, thereby fixing the energy dissipation reset component to the first connecting member or the second connecting member. In this way, the energy dissipation reset component will not shake in the up and down directions, and can only move along its axial direction to dissipate energy and reset. That is, after the structure is subjected to force, it will automatically return to its original state, thereby ensuring the stability of the device and avoiding the need for maintenance due to irreversible displacement.
[0033] 3) The energy-consuming reset component in the present invention has a reasonable structural arrangement. The energy-consuming reset component includes a limiting component and an elastic component. The limiting component limits the elastic component inside it on the circumferential side and the end side. An end clamp and a middle clamp are arranged in the first sleeve. The second steel strand mesh and the third steel strand mesh in the limiting component pass through the middle clamp so that the limiting component is fixed in the first sleeve.
[0034] 4) The energy-absorbing component in the present invention includes two connecting end plates, which are respectively connected to corresponding sleeves, and support members are respectively provided at the connecting ends. The support members are multiple steel bars. The steel bars at the two connecting end plates are all arranged through the flexible member. Under normal circumstances, the spacing between the steel bars on both sides is set. When the energy-absorbing component is subjected to force, the steel bars are constrained by the cylinder so that the steel bars are only deformed in the axial direction, thereby causing the flexible member to deform to dissipate energy. That is, the energy-absorbing component will consume part of the energy when subjected to force, thereby improving the reinforcement performance of the reinforcement device on the original structure.
[0035] 5) The elastic part in the present invention is an elastic part with gas inside. Under the setting of the second steel wire mesh and the third steel wire mesh, the elastic part is squeezed so that the elastic part is compressed as a whole. When the energy-consuming reset component is subjected to force, the two ends of the elastic part will telescope along the axial direction of the elastic part, which is beneficial to energy consumption and is beneficial to the overall automatic reset.

[0053] As introduced in the background technology, the existing technology has a problem that the lateral reinforcement effect of the transmission tower is generally poor. In order to solve the above technical problem, the present invention proposes a self-resetting reinforcement device for the lateral diaphragm of the transmission tower.
[0054] Example 1
[0055] In a typical embodiment of the present invention, reference is made to Figure 1As shown, a self-resetting reinforcement device for the transverse diaphragm of a transmission tower includes an edge node component fixed to the main material 1 of the transmission tower. The edge node components are connected by energy-absorbing components. The energy-absorbing components include a first connecting member 4 connected to the edge node component. The first connecting members 4 are connected by an energy-absorbing component 8. A support member 8-3 is arranged in the energy-absorbing component 8. The support member is arranged through a flexible member 8-5. The flexible member 8-5 is deformed by force and then consumes energy. The first connecting members 4 on both sides of the edge node component are connected by a second connecting member 9. The first connecting member 4 and the second connecting member 9 are both provided with an energy-absorbing reset component 6. The energy-absorbing reset component 6 includes an elastic member 6-6. The elastic member is compressed under normal conditions. When subjected to force, the elastic member can perform telescopic movement along its axial direction to consume energy. After the energy consumption is completed, the elastic member can be reset.
[0056] refer to Figure 3 As shown, the edge node component includes an external reinforcement angle steel 2 located on the outside of the transmission tower main material 1 and an internal reinforcement angle steel 3 located on the inside of the transmission tower main material 1. The external reinforcement angle steel 2 and the internal reinforcement angle steel 3 are connected by fasteners. The fasteners are bolts and nuts, and there is no need to drill holes in the transmission tower main material 1. Moreover, the height of the external reinforcement angle steel 2 and the internal reinforcement angle steel 3 can be the same, and the width is also compatible.
[0057] In this embodiment, the first connecting member 4 is a first angle steel, and the second connecting member 9 is a second angle steel. The heights of the first angle steel and the second angle steel are less than the height of the internal reinforcement angle steel 3; the ends of the first connecting member 4 and the second connecting member 9 are both provided with sealing plates, which can be welded to the first connecting member 4 and the second connecting member 9. The sealing plates are provided for connecting the first steel strand 5 with the first connecting member 4 or the second connecting member 9.
[0058] It is easy to understand that the first connecting parts 4 on both sides of the edge node component and the second connecting parts 9 connected to the first connecting parts on both sides form a right triangle, the side of the first angle steel is connected to the inner reinforcement angle steel 3 and the outer reinforcement angle steel 2 by bolts and nuts, the second angle steel is located on the lower side of the first angle steel, and one side surface of the second angle steel is connected to the lower side surface of the first angle steel by bolts and nuts, so that the setting position of the second angle steel is lower than the setting position of the first angle steel.
[0059] It should be noted that the two ends of the energy-consuming reset component 6 are respectively connected to the sealing plates at the ends of the first connecting member 4 or the second connecting member 9 through the first steel strand 5. Specifically, the first steel strand 5 passes through the sealing plate and is fastened by a nut, and the clamping member 7 clamps the energy-consuming reset component 6 to fix the energy-consuming reset component to the first connecting member 4 or the second connecting member 9.
[0060] refer to Figure 4 and Figure 5As shown, the energy-consuming reset component 6 includes a limiting component, and the elastic component 6-6 is located inside the limiting component. The limiting component limits the circumferential side and the end side of the elastic component, and the limiting component is stuck in the first sleeve.
[0061] In this embodiment, the limiting component includes a second steel strand mesh 6-4 and a third steel strand mesh 6-5. The lengths of the second steel strand mesh 6-4 and the third steel strand mesh 6-5 are both less than the length of the first sleeve. The second steel strand mesh 6-4 and the third steel strand mesh 6-5 are arranged side by side and staggered. One end of the third steel strand mesh 6-5 is arranged through one end of the second steel strand mesh 6-4, and one end of the second steel strand mesh 6-4 is arranged through one end of the third steel strand mesh 6-5. Limiting end plates 6-7 are respectively provided at one end of the second steel strand mesh and the third steel strand mesh, and the elastic member is located between the two limiting end plates.
[0062] Specifically, the second steel strand mesh 6-4 includes a limiting end plate, one end of multiple, such as four, second steel strands 6-8 are fixed at the limiting end plate 6-7, and can be welded and connected, and the interval between two adjacent second steel strands 6-8 is set at a set angle, and the other ends of multiple second steel strands 6-8 are respectively passed through the limiting end plate of the third steel strand mesh 6-5 and gathered together to be connected to the first steel strand 5; the third steel strand mesh 6-5 also includes a limiting end plate 6-7, one end of multiple, such as four, third steel strands 6-9 are fixed at the limiting end plate, and the interval between two adjacent third steel strands 6-9 is set at a set angle, and the other ends of multiple third steel strands 6-9 are respectively passed through the limiting end plate of the second steel strand mesh 6-4 and gathered together to be connected to the first steel strand 5 on the other side.
[0063] It is easy to understand that an end clamp 6-2 and a middle clamp 6-3 are provided in the first sleeve 6-1. The end clamp 6-2 can be welded and fixed in the first sleeve 6-1. The middle clamp 6-3 is welded and fixed in the middle of the first sleeve according to the prestressing requirement. The end clamp 6-2 and the middle clamp 6-3 are set at a distance. The end clamp 6-2 is located at both ends of the first sleeve. The middle clamp 6-3 is provided at two places. The end clamp 6-2 is an annular member, that is, the middle part of the end clamp is provided with a first opening for the first steel strand 5 to pass through. The middle clamp 6-3 is an annular member. The middle part of the middle clamp is provided with a second opening for the elastic member to pass through. The middle clamp is provided with multiple third openings along its thickness direction. The second steel strand and the third steel strand are respectively provided through the corresponding third openings. The diameters of the second steel strand 6-8 and the third steel strand 6-9 are smaller than the diameter of the first steel strand.
[0064] refer to Figure 6As shown, the annular surface of the elastic member is in contact with the second steel strand and the third steel strand, the elastic member 6-6 includes an inflatable cylinder, the inflatable cylinder 6-63 is supported by rubber material, the inflatable cylinder is filled with gas, the inflatable cylinder is circumferentially provided with a shell 6-64, and guide rods 6-65 are respectively provided at both ends of the inflatable cylinder, the guide rods 6-65 are provided through the shell, and a first limit plate is provided at one end of the guide rod, the first limit plate is fixedly connected to the inflatable cylinder, and a second limit plate 6-61 is provided at the other end of the guide rod, the second limit plate can contact with the limit end plate 6-7, and a guide plate 6-62 is also provided circumferentially with the guide rod, and a distance is set between the guide plate and the second limit plate, and the movement of the elastic member is guided by the second limit plate and the guide plate.
[0065] When the structure is under stress, the first steel strand 5 will apply pressure to the elastic member 6-6 through the limiting end plate 6-7, so that the elastic member 6-6 is compressed and applies a reverse force to achieve energy consumption. At the same time, the first steel strand 5 itself can also consume part of the energy. After the stress is over, the elastic member applies a reverse force to restore the structure to its initial state.
[0066] refer to Figure 6 As shown, the energy-absorbing component 8 includes two oppositely arranged connecting end plates 8-2, both of which are circular plates. The end of the first connecting member 4 is fastened to the connecting end plate 8-2, and the connecting end plates support the supporting members 8-3 respectively. The flexible member 8-5 is located on the inner side of the second sleeve 8-1, and the second sleeve 8-1 is connected to the connecting end plate on one side. A third sleeve 8-4 is arranged outside the second sleeve 8-1, and the third sleeve 8-4 is connected to the connecting end plate on the other side (can be welded). When the structure is subjected to stress, the flexible member 8-5 dissipates energy by deformation.
[0067] Specifically, the support member 8-3 includes multiple steel bars, and the multiple steel bars are staggered. The lengths of some of the multiple steel bars at the connecting end plate 8-2 are different, and the lengths of the steel bars located in the same straight line at the connecting end plates 8-2 on both sides are different, that is, steel bar groups of different lengths are welded at the corresponding connecting end plates 8-2, and the steel bars located in the same straight line are all inserted into the cylinder 8-6, and the long and short steel bars or two medium steel bars in groups on both sides are wrapped by the cylinder to constrain deformation in directions other than the axial direction of the steel bars. The cylinder 8-6 is located in the flexible member 8-5, and there is a set distance between the steel bars located in the same straight line at the two connecting end plates. When the transmission tower is subjected to force, the distance between the two steel bars in the cylinder can be reduced.
[0068] It should be noted that the support is composed of a group of steel bars of different lengths, specifically two short steel bars, two long steel bars, and one medium steel bar. Among the steel bar groups of different lengths on both sides, the long steel bars are grouped with the short steel bars, and the medium steel bars are grouped with the medium steel bars. There is a gap between the grouped steel bars, and the size of the gap depends on the maximum deformation of the flexible part.
[0069] In this embodiment, the flexible member 8-5 is a rubber column, both ends of which can contact the connecting end plate. The rubber column is provided with a plurality of openings, and the positions of the openings correspond to the positions of the steel bars.
[0070] refer to Figure 7 As shown, the clamping member includes a first clamping plate 7-2 and a second clamping plate 7-4 arranged opposite to each other. The first clamping plate and the second clamping plate are arranged opposite to each other in the circumferential direction of the energy-consuming reset component. The first clamping plate 7-2 and the second clamping plate 7-4 are both semi-annular plates. The two semi-annular plates are arranged opposite to each other to clamp the energy-consuming reset component. Extension plates are respectively provided on the top sides of the first clamping plate and the second clamping plate. The first clamping plate 7-2 is supported by the first support member 7-1, and the second clamping plate 7-4 is supported by the second support member 7-3. The first support member and the second support member are connected by fasteners such as bolts and nuts.
[0071] The first support member 7-1 and the second support member 7-3 are both bent, and the first support member and the second support member are respectively the first support plate and the second support plate. One side of the first connecting member 4 and the second connecting member 9 is inserted into the bending part of the first support member, and the other side of the first connecting member and the second connecting member is inserted into the bending part of the second support member, so that the first clamping plate 7-2 and the second clamping plate 7-4 can clamp the energy-consuming reset component.
[0072] The reinforcement device provided in this embodiment can simultaneously play the role of reinforcement and self-resetting energy consumption. After the structure is installed to form a whole, it reinforces the original transmission tower. When the structure is subjected to force, the first connecting member can consume energy regardless of whether it is in tension or compression, and the second connecting member can consume energy when it is in tension. The connection between the external reinforcement angle steel 2 and the internal reinforcement angle steel 3 and the main material 1 of the transmission tower is bolted, avoiding damage to the original structure by drilling or welding. The connection method between the remaining components is bolts and clamping members 7. The operation is simple and convenient for high-altitude construction. During construction, there is no need to shut down the reinforced transmission tower, thereby ensuring power supply reliability.
[0073] In addition, this embodiment also provides a working method of a transmission tower transverse diaphragm self-resetting reinforcement device, including the following contents:
[0074] Set edge node components at the main material 1 of the transmission tower;
[0075] Edge node components are connected through energy-consuming components;
[0076] The first connecting members on both sides of the edge node component are connected by a second connecting member, and energy-consuming reset components are provided at the first connecting member and the second connecting member;
[0077] In this way, the transmission tower main material 1, the edge node component, the first connecting member, the second connecting member, the energy-absorbing component and the energy-absorbing reset component 6 together form a force-bearing body. When the transmission tower is subjected to force, the elastic member can perform telescopic movement along its axial direction to consume energy, and the elastic member can be reset after the energy consumption is completed.
[0078] Example 2
[0079] The difference between this embodiment and the first embodiment is that:
[0080] The energy-consuming reset component is welded to the second connecting piece in advance, and does not need to be clamped by a clamping piece.
[0081] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
