Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power transmission towers, and particularly relates to a power transmission tower reinforcing component energy consumption structure, a reinforcing and reinforcing device and a method. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] As the backbone support of high-voltage transmission lines, a power transmission tower structure is a typical high-rise steel structure with a large height-width ratio and strong wind sensitivity. Under the action of fluctuating wind caused by strong wind, especially typhoon or strong convective weather, the power transmission tower structure is prone to large vibration, stress concentration in the connection area of the main material and the node, and thus buckling, instability and even overall collapse, causing a "domino effect" chain damage. As a national important lifeline project, once a tower collapse accident occurs, it will lead to a large-scale and long-time power supply interruption, causing not only huge direct economic losses, but also a serious impact on social production order and public safety.

[0004] At present, a considerable part of the many high-voltage transmission towers in service are built according to the early design specifications with lower load standards, and their inherent wind-resistant bearing capacity margin is insufficient. At the same time, these towers have been in operation for many years, and have been subjected to alternating loads such as wind vibration and icing for a long time, which may cause material performance degradation and node connection loosening, resulting in further decrease in the overall wind-resistant ultimate bearing capacity. In the face of the increasing demand for power transmission capacity and possibly more extreme weather conditions, it is urgent to comprehensively reinforce and reinforce these in-service towers to ensure the safe and stable operation of the power grid. Compared with the line reconstruction with huge investment and long cycle, targeted reinforcement and reconstruction of the existing tower is an economical, efficient and minimal impact solution.

[0005] The current reinforcement method mainly adds auxiliary materials to constrain the original deformation structure through clamps, bolts or welding. These components only improve the structural strength of the main material, and do not set up dissipation components to absorb and dissipate vibration energy.

[0006] The inventor has also found that bolt reinforcement will damage the structural strength of the original main material, and welding reinforcement will affect the stress state of the main material, leading to increased brittleness of the steel material. Some clamps are difficult to closely fit the main material, resulting in low transmission efficiency, limited bearing capacity improvement, no need to stop power supply during construction, simple and convenient operation, and significantly reduced difficulty and duration of high-altitude operation. In addition, due to the complex structure of the node area, it is difficult to effectively strengthen the node area with complex stress. SUMMARY

[0035] It should be noted that the following detailed description is illustrative only and is intended to provide further description of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0036] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should be understood that when the terms "comprise" and / or "include" are used in this specification, there is a presence of the features, steps, operations, devices, components and / or their combinations; As introduced in the background, the prior art has the problem of reinforcing the main material of the transmission tower without setting the dissipation member to dissipate the vibration energy. In order to solve the above technical problem, the present application provides a kind of energy dissipation structural member for transmission tower reinforcing member.

[0037] Example one In a typical embodiment of the present application, reference is made to Figure 5As shown in the figure, a power transmission tower reinforcing member energy dissipation structure includes a sleeve shell 8-4, two connecting plates 8-2 are arranged in the sleeve shell 8-4, the connecting plates 8-2 are arranged along the radial direction of the sleeve shell 8-4, the two connecting plates 8-2 are arranged at a distance, the connecting plates 8-2 are connected with connecting rods 8-1, the connecting rods 8-1 pass through the ends of the sleeve shell 8-4 and are connected with the reinforcing member, damping blocks 8-5 are arranged between the two connecting plates 8-2 in the sleeve shell 8-4, between the connecting plates 8-2 and the ends of the sleeve shell 8-4, limiting magnets 8-3 are arranged on the two end faces of the connecting plates 8-2, and limiting magnets 8-3 are also arranged on the inner end face of the sleeve shell 8-4 and are fixed in the sleeve shell 8-4.

[0038] Reference Figure 5 As shown in the figure, the connecting rods 8-1 are two, the two connecting rods 8-1 are arranged in opposite directions, the two connecting rods pass through the ends of the sleeve shell 8-4, the connecting rods 8-1 are connected with the center positions of the connecting plates 8-2, the connecting rods 8-1 and the connecting plates 8-2 form an integral whole, limiting magnets 8-3 are arranged on both sides of each connecting plate 8-2, the limiting magnets 8-3 are used to provide damping force and restoring force, three damping blocks 8-5 are arranged in the sleeve shell 8-4, the two side damping blocks are provided with holes for the connecting rods 8-1 to pass through, the middle damping block is in contact with the two connecting plates 8-2, the two side damping blocks are in contact with the connecting plates 8-2 and the ends of the sleeve shell 8-4, and the operating principle of this part is that when the structure connected with the connecting rods 8-1, such as the first reinforcing member 2, deforms, the connecting rods 8-1 will displace, the connecting rods 8-1 drive the connecting plates 8-2 to extrude the damping blocks 8-5 to dissipate energy, at the same time, the distance between the limiting magnets 8-3 at the two connecting plates will become smaller, repulsion force will be generated between the limiting magnets 8-3 to dissipate energy, and the limiting magnets 8-3 limit the maximum displacement of the connecting rods 8-1 and the connecting plates 8-2.

[0039] It should be explained that if the two connecting rods 8-1 move towards the middle part of the energy dissipation structure, the connecting plates 8-2 will extrude the inner damping blocks 8-5 to dissipate energy in the first stage, in the extrusion process, the connecting plates will overcome the repulsion force of the limiting magnets 8-3 to dissipate energy in the second stage, and then the connecting plates 8-2 will be reset under the repulsion force of the limiting magnets 8-3; if one side of the connecting rod 8-1 moves towards the middle part of the energy dissipation structure and the other side of the connecting rod 8-1 moves towards the outside, one side of the connecting plate 8-2 will extrude the side damping block 8-5 to dissipate energy in the first stage, if the distance between the two connecting plates 8-2 becomes smaller, the repulsion force of the limiting magnets 8-3 will be overcome to dissipate energy in the second stage, that is, effective energy dissipation will be carried out in the process of tension or compression of the connecting rod 8-1.

[0040] Specifically, the material of the damping block 8-5 can be selected from rubber materials, and the inner diameter of the damping block 8-5 is matched with the inner diameter of the sleeve shell 8-4.

[0041] It should be explained that a plurality of limiting magnets 8-3 are arranged at the two ends of the connecting plate 8-2 close to the outer circumferential surface thereof, and the positions of the limiting magnets at the two ends of the connecting plate 8-2 correspond to each other. The adjacent two limiting magnets 8-3 at each end are arranged at a set angle, and the limiting magnets 8-3 are specifically existing magnets. The limiting magnets at the inner side of the two connecting plates 8-2 have the same magnetism as the magnetism of the end of the connecting plate 8-2 away from the connecting plate 8-2, so as to generate repulsion force, which is beneficial to the reset of the connecting plate 8-2 and the dissipation of energy. The limiting magnets at the two sides of the connecting plate 8-2 have opposite magnetism to the magnetism of the end of the connecting plate connected to the limiting magnets, so as to have adsorption effect on the limiting magnets at the other end of the connecting plate. Of course, the limiting magnets 8-3 at the two sides of the connecting plate 8-2 are fixed to the end surface of the connecting plate 8-2, so as to ensure the stable arrangement of the limiting magnets.

[0042] Specifically, the inner end surface of the sleeve shell 8-4 is also arranged with a limiting magnet 8-3, and the magnetism of the limiting magnet away from the end surface of the sleeve shell 8-4 is opposite to the magnetism of the limiting magnet 8-3 at the outer side of the connecting plate 8-2, and the two have repulsion effect, which is beneficial to the reset of the connecting plate. The outer circumferential surface of the sleeve shell 8-4 is provided with a fixing ring 8-7, the inner circumferential surface of the fixing ring 8-7 is provided with a travel switch 8-6, and the circumferential surface of the sleeve shell 8-4 is provided with two travel switch reserved holes 8-10. The travel switch reserved holes 8-10 are used for the detection head of the travel switch 8-6 to enter the inside of the sleeve shell 8-4, so as to form an energy dissipation sleeve 8 with self-monitoring. The travel switch 8-6 is connected with a signal transmitter 8-8 and a solar power supply panel 8-9 respectively. The two sides of the signal transmitter 8-8 are connected with the two ends of the fixing ring 8-7 respectively, and the solar power supply panel 8-9 is fixed to the outer side of the signal transmitter 8-8. The solar power supply panel 8-9 converts solar energy into electric energy and supplies power to the signal transmitter and the travel switch 8-6. The inside of the fixing ring is a wire channel, the signal transmitter is connected with the travel switch 8-6 through wires, and the travel switch sends the detected data to the controller through the signal transmitter.

[0043] It is easy to understand that the fixed ring 8-7 is fixed to the middle section of the sleeve shell 8-4, and the detection head of the travel switch is normally aligned with the middle damping block. When the connecting plate moves to the position of the detection head, the travel switch will detect it, so that the travel switch detection head can obtain whether the connecting plate moves to the middle section of the sleeve shell 8-4. The working principle of the travel switch is: when the structure is damaged, a large displacement will be generated, which will drive the connecting plate 8-2 to also generate a continuous large displacement. The travel switch 8-6 can obtain the corresponding information when the connecting plate has a large displacement. When the connecting plate is detected to be in the middle position for a long time (more than 2 minutes), a signal will be sent to the signal transmitter 8-8 through the line in the line channel. After the signal transmitter 8-8 receives the signal, it will send information to the controller. The controller is fixed to the bottom side of the power transmission tower. The controller is a PLC controller or other type of controller, so that the damage of the reinforced part can be discovered in time. The power required in this process is provided by the solar power supply panel 8-9.

[0044] It is easy to understand that the energy dissipation sleeve 7 without self-monitoring is less than the energy dissipation sleeve 8 with self-monitoring. The travel switch 8-6, the fixed ring 8-7, the signal transmitter 8-8, the solar power supply panel 8-9 and the travel switch reserved hole 8-10 are omitted. The rest of the components and the arrangement between the components are the same as the energy dissipation sleeve 8 with self-monitoring.

[0045] Example two The present embodiment provides a power transmission tower reinforcing and reinforcing device, referring to Figure 8 As shown in the figure, it comprises a reinforcing member 13 arranged on the side of the reinforced main material 1. The reinforcing member 13 is attached to the reinforced main material and the internal structure of the reinforcing assembly is connected to each other. The reinforcing member 13 is provided with a plurality of energy dissipation structural members for reinforcing members of power transmission towers as described in example one.

[0046] Specifically, the reinforcing member comprises a first reinforcing member 2 and a second reinforcing member 3, each of which is provided with two, i.e. two first reinforcing members 2 and two second reinforcing members 3. The first reinforcing member 2 and the second reinforcing member 3 are arranged on the side of the reinforced main material 1 at intervals, i.e. the two first reinforcing members 2 are arranged opposite to each other, and the two second reinforcing members 3 are arranged opposite to each other. Adjacent reinforcing members are fixedly connected, specifically connected by bolts and nuts. It is also convenient to separate the first reinforcing member 2 and the second reinforcing member 3 for the subsequent replacement of the reinforcing member. The first reinforcing member 2 and the second reinforcing member are in close contact with the reinforced main material 1. The first reinforcing member 2 is arranged with an energy dissipation sleeve 7 without self-monitoring and an energy dissipation sleeve 8 with self-monitoring. The size, arrangement position and number of the two kinds of energy dissipation sleeves can be adjusted according to actual engineering needs.

[0047] It is easy to understand that the first reinforcing member 2 is an arc-shaped member, the covering angle of the first reinforcing member is 90°, the second reinforcing member 3 is an L-shaped angle steel, so that the second reinforcing member 3 and the adjacent first reinforcing member 2 form a containing space of the reinforced main material 1, and during reinforcement, one of the second reinforcing members 3 is arranged on the inner side of the reinforced main material 1, and the other second reinforcing member 3 is arranged on the outer side of the reinforced main material 1, the lengths of the first reinforcing member 2 and the second reinforcing member 3 are shorter than the length of the reinforced main material 1, the widths of the two sides of the second reinforcing member 3 are greater than the widths of the two sides of the reinforced main material 1, and the side of the first reinforcing member 2 exceeds the reinforced main material 1, so as to facilitate the connection of adjacent two reinforcing members.

[0048] Specifically, the first reinforcing member 2 and the second reinforcing member 3 are provided with bolt holes 6, and the two reinforcing members are connected together with the reinforced main material 1 by bolts 4 and nuts 5 through the bolt holes 6 and form a reinforced whole, the first reinforcing member 2 is provided with a plurality of energy dissipation structural members on the side away from the reinforced main material 1, the adjacent two energy dissipation structural members are arranged at a distance, the length direction of the energy dissipation structural member is arranged along the longitudinal cross-sectional direction (width direction) of the reinforced main material 1, so as to absorb vibration energy, and at least one of the plurality of energy dissipation structural members is a self-monitoring energy dissipation sleeve 8.

[0049] Considering that the structure also needs to be reinforced at the node, reinforcing members are arranged on the two sides of the node along the length direction of the reinforced main material 1, and a node reinforcing member 14 is arranged at the node, the node reinforcing member connects the reinforcing members 13, as shown in Figure 1 , the node reinforcing member includes a node bolt 9 and a node bolt sleeve 10, which are connected through a node bolt hole 11 to form a main material node reinforcing system, the end of the first reinforcing member close to the node is respectively provided with a node plate, and the self-monitoring energy dissipation sleeve 8 is arranged along the length direction of the reinforced main material 1, as shown in Figure 6 , Figure 7 and Figure 9 , the two ends of the self-monitoring energy dissipation sleeve 8 are respectively connected with the node bolt sleeve 10, the node bolt sleeve is provided with an internal thread, the node bolt 9 passes through the node plate and is connected with the node bolt sleeve 10 through the thread structure, and the self-monitoring energy dissipation sleeve 8 is arranged in the middle of the node bolt sleeve 10 on the two sides, wherein the size and position of the self-monitoring energy dissipation sleeve are adjusted according to the inclined material to avoid conflict with the position of the inclined material; the node reinforcing member 14 connects the two ends of the first reinforcing member 2 to avoid interference with the inclined main material 12 at the node.

[0050] , the two ends of the self-monitoring energy dissipation sleeve 8 are respectively connected with the node bolt sleeve 10, the node bolt sleeve is provided with an internal thread, the node bolt 9 passes through the node plate and is connected with the node bolt sleeve 10 through the thread structure, and the self-monitoring energy dissipation sleeve 8 is arranged in the middle of the node bolt sleeve 10 on the two sides, wherein the size and position of the self-monitoring energy dissipation sleeve are adjusted according to the inclined material to avoid conflict with the position of the inclined material; the node reinforcing member 14 connects the two ends of the first reinforcing member 2 to avoid interference with the inclined main material 12 at the node.

[0051] In the device, all component connections to be completed on site are achieved by bolt connection or bolting, without the need for welding or other high-difficulty construction operations in the air, and the structure is simple and easy to operate, thereby reducing the difficulty of high-altitude operation.
