Description

Technical Field

[0001] This utility model relates to the field of ultra-high voltage transmission tower technology, and in particular to an auxiliary stabilization structure for ultra-high voltage transmission towers on permafrost foundations. Background Technology

[0002] Ultra-high voltage (UHV) transmission towers are a key component of UHV transmission lines, used to support and fix UHV transmission conductors, ensuring the stable operation of the transmission lines. UHV transmission lines also have long-distance, high-capacity power transmission capabilities.

[0003] When in use, the existing high-voltage transmission tower bases are usually made of concrete, which has a simple structure and low seismic performance and load-bearing capacity, which is not conducive to the protection and reinforcement of the transmission tower. Secondly, the existing high-voltage transmission tower bases do not have traction parts. When facing strong convective weather, the bottom of the transmission tower and the base lack traction and fixing force, which makes the transmission tower prone to tilting.

[0004] The existing patent (publication number: CN220469515U) discloses an anti-seismic high-voltage transmission tower base suitable for high-voltage transmission towers. This device is equipped with a fixing block and a traction block. The fixing rod is placed on the inner side of the fixing block and fixed to the fixing block by fixing bolts. The traction block is fixed to the upper end of the base body by a threaded rod. One end of the traction rope is fixed to a buckle, and the other end is fixed to a support rod to provide traction force to the transmission tower, increase the stability of the transmission tower and the base body, and enable the transmission tower to be pulled by the traction rope when affected by severe weather, so as to prevent the transmission tower from tilting.

[0005] Existing patents offer solutions to the aforementioned problems, but the traction force they provide cannot be adjusted. This makes it difficult to use fine-tuning of the traction force to stabilize the tilted high-voltage transmission tower when it tilts, thus leaving the high-voltage transmission tower with significant risks in subsequent use.

[0006] To address this, an auxiliary stabilization structure for ultra-high voltage transmission towers on permafrost foundations is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an auxiliary stabilization structure for ultra-high voltage transmission towers on permafrost foundations. This structure addresses the problem that existing traction forces cannot be adjusted, making it difficult to stabilize the tilted tower by fine-tuning the traction force. Consequently, the towers still face significant risks during subsequent use.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary stabilization structure for ultra-high voltage transmission towers on permafrost foundations, comprising a base, a transmission tower body fixedly connected to the top of the base, an auxiliary component fixedly connected to the surface of the transmission tower body, and an adjustment component provided on the surface of the auxiliary component;

[0009] The adjusting assembly includes a slide rod, a first engaging block slidably connected to the surface of the slide rod, fixing bolts movably connected to the inner walls on both sides of the first engaging block, a second engaging block movably connected to the surface of the fixing bolts, the side of the first engaging block closer to the second engaging block being in close contact with the second engaging block, a nut threadedly connected to the surface of the fixing bolt, the nut being in contact with the first engaging block, and a threaded sleeve fixedly connected to the side of the second engaging block away from the first engaging block, the inner wall of the threaded sleeve being threadedly connected to a bidirectional screw.

[0010] Preferably, the auxiliary component includes a square frame, the inner wall of which is fixedly connected to the surface of the transmission tower body, a connecting ring is fixedly connected to the surface of the square frame, and a cable is in contact with the inner wall of the connecting ring.

[0011] Preferably, the other end of the cable is fixedly connected to a connecting block, and there are four connecting blocks in total. The bottom of the connecting block is fixedly connected to the top of the base.

[0012] Preferably, the surface of the connecting block is provided with a corrosion-resistant coating.

[0013] Preferably, both ends of the slide rod are fixedly connected to limit blocks, the limit blocks are circular, and a rubber pad is provided on the side of the limit block near the slide rod.

[0014] Preferably, an arc-shaped groove is provided on the opposite side of the first locking block and the second locking block, and the inner wall of the arc-shaped groove is fixedly connected to the surface of the cable.

[0015] Preferably, both ends of the bidirectional screw are fixedly connected to anti-detachment blocks, and the bottom of the anti-detachment blocks is fixedly connected to hexagonal blocks.

[0016] Preferably, the bottom of the base is fixedly connected with anchor nails, and the top of the base is fixedly connected with a reinforcing block. The top of the reinforcing block is provided with a mating groove, and the inner wall of the mating groove is fixedly connected to the surface of the transmission tower body.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up a base, a transmission tower body, and auxiliary components. The base is made of cast concrete, which allows the base to provide a large load-bearing capacity. Under the support of the base, the transmission tower body will not come into direct contact with the frozen ground, thus avoiding the tilting of the transmission tower body due to the melting of the frozen ground. The auxiliary components can assist in stabilizing the transmission tower body and provide it with a strong traction force, thereby increasing the stability of the transmission tower body in use.

[0019] 2. This application sets up an adjustment component, which, after rotating, can adjust the traction force of the auxiliary component, thereby preventing the transmission tower body from tilting again due to insufficient traction force when it tilts. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] An auxiliary stabilization structure for an ultra-high voltage transmission tower on a permafrost foundation includes a base 1, a transmission tower body 2 fixedly connected to the top of the base 1, an auxiliary component 3 fixedly connected to the surface of the transmission tower body 2, and an adjustment component 4 provided on the surface of the auxiliary component 3.

[0031] The adjusting assembly 4 includes a slide rod 401, a first engaging block 402 slidably connected to the surface of the slide rod 401, fixing bolts 403 movably connected to the inner walls on both sides of the first engaging block 402, a second engaging block 404 movably connected to the surface of the fixing bolts 403, the side of the first engaging block 402 closest to the second engaging block 404 in close contact with the second engaging block 404, a nut 405 threadedly connected to the surface of the fixing bolts 403, the nut 405 in contact with the first engaging block 402, and a threaded sleeve 406 fixedly connected to the side of the second engaging block 404 away from the first engaging block 402, and a bidirectional screw 407 threadedly connected to the inner wall of the threaded sleeve 406.

[0032] In this embodiment: by setting up a base platform 1, a transmission tower body 2, an auxiliary component 3, and an adjustment component 4, the base platform 1 can provide load-bearing capacity and installation space for the transmission tower body 2, preventing the transmission tower body 2 from directly contacting the frozen ground. The transmission tower body 2 can be connected to the auxiliary component 3, which can then provide strong traction force to the transmission tower body 2, preventing it from tilting and falling over due to lack of traction force when tilting. The adjustment component 4 can adjust the traction force, preventing the tilted transmission tower body 2 from tilting again due to insufficient traction force.

[0033] Specifically, such as Figure 4 As shown, the auxiliary component 3 includes a square frame 301. The inner wall of the square frame 301 is fixedly connected to the surface of the transmission tower body 2. A connecting ring 302 is fixedly connected to the surface of the square frame 301. A cable 303 contacts the inner wall of the connecting ring 302.

[0034] Specifically, such as Figure 4As shown, the other end of the cable 303 is fixedly connected to a connecting block 5, and there are four connecting blocks 5 in total. The bottom of the connecting block 5 is fixedly connected to the top of the base 1.

[0035] Specifically, such as Figure 4 As shown, the surface of the connecting block 5 is provided with a corrosion-resistant coating 6.

[0036] In this embodiment: the square frame 301 allows it to be connected to the transmission tower body 2 and provides installation space for the connecting ring 302. The connecting ring 302 can be connected to the cable 303, and the cable 303 provides strong traction to the transmission tower body 2 through the connecting ring 302 and the square frame 301. The connecting block 5 allows it to be connected to the cable 303, and the connection between the connecting block 5 and the base 1 provides a strong fixing point for the cable 303, preventing a decrease in the traction of the cable 303 due to instability of the fixing point. The corrosion-resistant coating 6 protects the connecting block 5 and prevents it from being damaged at low temperatures.

[0037] Specifically, such as Figure 5 , Figure 7 As shown, both ends of the slide bar 401 are fixedly connected to limit blocks 7. The limit blocks 7 are circular, and a rubber pad 8 is provided on the side of the limit block 7 near the slide bar 401.

[0038] Specifically, such as Figure 7 As shown, the first locking block 402 and the second locking block 404 each have an arc-shaped groove 9 on their opposite sides, and the inner wall of the arc-shaped groove 9 is fixedly connected to the surface of the cable 303.

[0039] In this embodiment: the limiting block 7 limits the sliding range of the slide bar 401, preventing it from sliding too far and detaching. The rubber pad 8 protects the limiting block 7, preventing damage when it comes into contact with the first engaging block 402. The arc groove 9 guides the installation position of the cable 303 and provides installation space for it.

[0040] Specifically, such as Figure 5 , Figure 6 , Figure 7 As shown, anti-detachment blocks 10 are fixedly connected to both ends of the bidirectional screw 407, and hexagonal blocks 11 are fixedly connected to the bottom of the anti-detachment blocks 10.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, the bottom of the base 1 is fixedly connected with anchor nails 12, and the top of the base 1 is fixedly connected with a reinforcing block 13. The top of the reinforcing block 13 is provided with a mating groove 14, and the inner wall of the mating groove 14 is fixedly connected to the surface of the transmission tower body 2.

[0042] In this embodiment: by setting the anti-detachment block 10, the anti-detachment block 10 can limit the rotation range of the bidirectional screw 407, so as to prevent the bidirectional screw 407 from separating from the screw sleeve 406 due to excessive rotation range. By setting the anchor nail 12, the anchor nail 12 can increase the connection strength between the base 1 and the frozen ground. By setting the reinforcing block 13 and the mating groove 14, the reinforcing block 13 can reinforce the transmission tower body 2 with the mating groove 14.

[0043] Working principle: When the traction force needs to be adjusted, the double-acting screw 407 can be rotated, causing it to rotate within the screw sleeve 406. Guided by the thread pattern, the screw sleeve 406 drives the second locking block 404 to move. Because the second locking block 404 is connected to the first locking block 402 by a fixing bolt 403 and a nut 405, the movement of the second locking block 404 drives the first locking block 402 to move as well. During movement, the sliding connection with the slide bar 401 ensures that the position of the first locking block 402 will not deviate. When the first locking block 402 and the second locking block 404 move, the arc groove 9 drives the cable 303 to move relative to each other, thereby adjusting the traction force of the cable 303. After the traction force of the cable 303 is adjusted, the adjusted traction force can be applied to the transmission tower body 2 through the connecting ring 302 and the square frame 301 until the adjustment is completed.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
