Description

Technical Field

[0001] The present application relates to the field of emergency repair equipment for ultra-high voltage transmission lines, and in particular to an ultra-high voltage universal fully insulated emergency repair tower. Background Art

[0002] UHV transmission lines are an important part of the modern power system, responsible for long-distance, large-capacity power transmission. However, since UHV transmission lines usually cross complex terrain and harsh environments, such as mountains, canyons, deserts, etc., these environmental conditions can easily lead to transmission line failures and require timely repairs. Therefore, the UHV universal fully insulated repair tower came into being. It can not only be quickly built, but also effectively ensure the safety and reliability of the repair work, greatly improving the repair efficiency and the stability of the power grid operation.

[0003] Existing UHV repair towers mostly adopt traditional steel structure design, mainly including bottom support structure, middle connection structure and top working platform. These repair towers usually fix various components by rigid connection. Although they can provide certain stability and bearing capacity, in actual use, due to the influence of natural environment (such as wind load, earthquake, etc.), the repair towers are prone to large vibration and impact, which may cause structural fatigue or even damage.

[0004] Therefore, how to design a UHV repair tower that can improve stability has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to improve the stability of the UHV emergency repair tower, the present application provides an UHV universal fully insulated emergency repair tower.

[0006] The present application provides a universal UHV fully insulated emergency repair tower adopting the following technical solution: A universal ultra-high voltage fully insulated emergency repair tower, comprising a bottom support part, a top support part and a buffer assembly; In the circumferential direction of the virtual circle, the buffer components are distributed in plurality; the buffer components are connected between the bottom support portion and the top support portion, and the buffer components include: A support seat, the support seat is fixedly connected to the bottom support portion; A sliding seat, the sliding seat is fixedly connected to the top support portion, the sliding seat is slidably connected to the support seat along a virtual circumferential direction, a limiting portion for limiting the sliding angle range of the sliding seat is formed on the sliding seat, and the sliding angle range of the sliding seat is less than 10°; and A first elastic member, one end of which is fixedly connected to the sliding seat, and the other end of which is fixedly connected to the supporting seat, and the first elastic member is used to buffer the impact force of the rotation of the sliding seat.

[0007] By adopting the above technical solution, the sliding seat in the buffer assembly can slide within a small range in the virtual circumferential direction, so that when the transmission line is subjected to external impact or vibration, the first elastic member can effectively absorb and disperse the energy, reducing the impact on the top support part; at the same time, the existence of the first elastic member can not only provide a buffering effect, but also play a role in the resetting process of the sliding seat, ensuring the structural stability of the entire repair tower. In addition, the design of the limiter allows the sliding range of the sliding seat to be strictly controlled within °, further improving the controllability and safety of the repair tower.

[0008] Optionally, the bottom support portion includes: A first side column, wherein the first side column is parallel to the first direction, and two first side columns are distributed in the second direction; and A first crossbeam, wherein the first crossbeam is parallel to the second direction, and both ends of the first crossbeam are respectively fixedly connected to a corresponding one of the first side columns; The support seat is fixedly connected to the first side column, and at least one buffer component is correspondingly distributed on each of the first side columns.

[0009] By adopting the above technical solution, at least one buffer assembly is arranged on each first side column. Through the relative sliding between the sliding seat and the supporting seat and the buffering effect of the first elastic member, the external impact force is effectively absorbed and dispersed, thereby improving the stability and safety of the repair tower.

[0010] Optionally, the top support portion includes: second side columns, the second side columns are parallel to the first direction, and each of the second side columns is fixedly connected to a corresponding first side column; and A second crossbeam, wherein the second crossbeam is parallel to the second direction, and both ends of the second crossbeam are respectively fixedly connected to a corresponding second side column.

[0011] By adopting the above technical solution, the setting of the second crossbeam effectively disperses the top load, reduces the stress on individual components, and extends the service life of the repair tower.

[0012] Optionally, the support seat is fixedly connected to a limit block, and in the circumferential direction of the virtual circle, the sliding seat is provided with the limit blocks at both ends of the sliding track respectively; one end of the first elastic member is fixedly connected to the limit block, and the other end is fixedly connected to the sliding seat, and the virtual circle stores a pre-pressure that drives the sliding seat to move along the axis of the virtual circle.

[0013] By adopting the above technical solution, the cooperation between the limit block and the first elastic member ensures the stability of the sliding seat sliding in the virtual circumferential direction. At the same time, the pre-pressure provided by the first elastic member can be quickly reset after the external force disappears, effectively reducing the vibration and swing of the transmission line caused by wind or other external factors, thereby improving the overall stability and safety of the repair tower.

[0014] Optionally, a force unloading component is further included, and the force unloading component includes: A central axis, wherein the central axis is parallel to the first direction and is coaxial with the virtual circle, and the central axis is fixedly connected to the bottom support portion; and A buffer stopper rod, one end of which is rotatably connected to the central shaft body around the axis of the central shaft body, and the other end of which is a movable end. In the circumferential direction of the virtual circle, the movable end is located between the limit block and the sliding seat; The buffer stop rod is correspondingly arranged between the sliding seat and each of the limiting blocks.

[0015] By adopting the above technical solution, when the transmission line is subjected to external force, the force unloading assembly can effectively disperse and absorb the external impact force through the rotation of the buffer bar and the buffering effect of the elastic part, and transfer the impact force to the middle part of the bottom support part, thereby reducing the two sides of the bottom support part from being twisted into a twist shape under force, thereby reducing damage to the repair tower structure and enhancing the overall stability and safety of the repair tower.

[0016] Optionally, the force unloading component further includes: A second elastic member, one end of which is fixedly connected to the movable end of the buffer stop rod, and the other end of which is fixedly connected to the limit block; When the second elastic member is in a restorable deformation posture, it has a force that drives the sliding seat to move so as to increase the distance between the sliding seat and the limiting block.

[0017] By adopting the above technical solution, the second elastic member can generate elastic force when subjected to external impact, thereby effectively buffering the relative displacement between the sliding seat and the limit block, reducing the damage to the sliding seat and the limit block caused by the impact force, and improving the stability and reliability of the entire buffer assembly. At the same time, the pre-pressure of the second elastic member increases the distance between the sliding seat and the limit block, further improving the buffering capacity of the buffer assembly, ensuring that the sliding seat can be quickly reset when the transmission line shakes, avoiding structural fatigue caused by long-term stress, and extending the service life of the repair tower; further, it can reduce the direct collision between the sliding seat and the limit block, and instead disperse a part of it to the central axis, and the central axis is located at the center of the virtual circle, therefore, it can further reduce the two sides of the bottom support part from being twisted into a twisted shape under stress.

[0018] Optionally, in the second direction, the distances between the central axis and the two first side columns are equal.

[0019] By adopting the above technical solution, the spacing between the central axis and the two first side columns is ensured to be equal, so that the entire repair tower is more evenly stressed, the stability and balance of the structure are improved, and the risk of structural deformation or damage due to uneven stress is reduced.

[0020] Optionally, it further includes a middle upright pole, which is parallel to the first direction, fixedly connected to the first crossbeam, and in the second direction, the middle upright pole is located between the first side columns on both sides.

[0021] By adopting the above technical solution, the setting of the middle pole improves the overall rigidity and structural stability of the emergency repair tower, especially in strong winds or bad weather conditions, which can effectively prevent the emergency repair tower from tipping over or deforming. At the same time, the middle pole is fixedly connected to the first crossbeam, so that the force of the entire bottom support part is more uniform, further enhancing the bearing capacity of the emergency repair tower. In addition, the middle pole is located between the first side columns on both sides, ensuring the balance of the emergency repair tower in the second direction, avoiding imbalance caused by excessive force on one side.

[0022] Optionally, the second side column and the second cross beam are both made of insulating materials.

[0023] By adopting the above technical solution, the second side column and the second crossbeam of the UHV general-purpose fully insulated repair tower are made of insulating materials, which effectively improves the safety of the repair tower and avoids safety accidents caused by conduction.

[0024] Optionally, the top support portion further includes a traction rope, one end of which is fixedly connected to the second side column.

[0025] By adopting the above technical solution, the setting of the traction rope improves the overall stability of the repair tower, especially when it is affected by the external environment (such as strong wind), the traction rope can effectively disperse and alleviate the forces from different directions, ensuring the stability of the repair tower under harsh conditions.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The existence of the first elastic member can not only provide a buffering effect, but also play a role in the resetting process of the sliding seat, ensuring the structural stability of the entire repair tower; 2. When the transmission line is subjected to external forces, the force unloading assembly can disperse and absorb the external impact force through the rotation of the buffer bar and the buffering effect of the elastic member, thereby enhancing the overall stability and safety of the repair tower; 3. The setting of the traction rope improves the overall stability of the repair tower, especially when it is affected by the external environment (such as strong wind). The traction rope can effectively disperse and alleviate the forces from different directions, ensuring the stability of the repair tower under harsh conditions. BRIEF DESCRIPTION OF THE DRAWINGS
