Description

Technical Field

[0001] The present invention relates to the technical field of electric poles, in particular to an anti-falling electric pole for an electric power grid. Background Art

[0002] In the field of power grid construction, utility poles serve as critical infrastructure supporting transmission lines, and their structural stability is directly related to the reliability and safety of power transmission. Traditional power poles are typically installed by welding embedded components to the main body of the pole, which can meet basic power transmission requirements to a certain extent.

[0003] However, in practice, utility poles face numerous challenges due to their long-term exposure to complex outdoor environments. For one thing, the effects of wind in the natural environment cannot be ignored, especially in coastal areas or open areas, where strong winds frequently occur, exerting enormous horizontal thrust on utility poles. Long-term wind impacts can gradually induce fatigue stress at the welds between the poles and embedded components, leading to microcracks in the welds. Furthermore, rainwater erosion is a serious problem, as the acidic substances in rainwater accelerate metal corrosion at the welds, further weakening the welds. Furthermore, accidental collisions, such as vehicle strikes, can directly damage welds. Once a weld becomes loose or damaged, the overall structural stability of the pole is significantly affected, and the pole can tilt or even collapse under even the slightest external force, causing widespread power outages and severe losses to the economy and residents' lives.

[0004] With the continuous growth of electricity demand and the continued expansion of the power grid, utility poles are being used in a wider range of applications and in increasingly complex and diverse environments. In areas prone to natural disasters, such as earthquake zones and areas with strong winds, utility poles face even more severe challenges.

[0005] During an earthquake, the ground vibrates and shifts violently, subjecting utility poles to enormous dynamic external forces, severely impacting their foundations and overall structure. Traditional utility poles rely primarily on the connection between embedded components and the ground, as well as their inherent structural strength, to resist these forces. However, this single anti-toppling approach often proves inadequate in the face of extreme natural disasters like earthquakes. Earthquake-induced ground deformation can loosen the connection between embedded components and the ground, destabilizing the pole's foundation. Furthermore, the immense external forces can exceed the pole's inherent resistance, causing it to tilt or collapse.

[0006] Furthermore, the installation and transportation of utility poles are crucial steps in the construction and maintenance of power grids, with their efficiency and quality directly impacting the overall project schedule and cost. Traditional utility poles and their accompanying embedded components present numerous inconveniences during installation and transportation. Conventional utility poles and embedded columns typically utilize fixed connections, resulting in large volumes and irregular shapes, which require significant space during transportation. This not only increases the demand for transport vehicles and costs, but also increases the risk of component damage due to bumps and collisions during transportation. Especially in areas with complex terrain and inaccessible transportation, large transport vehicles are unable to reach them, making transportation even more challenging and further limiting the timely supply and installation of utility poles.

[0007] During installation, traditional connection methods are cumbersome, labor-intensive, and time-consuming. For example, connecting the deferred payment tray to the embedded tray may require complex fixing and adjustment using multiple tools. The installer's skill level and proficiency significantly impact the quality of the installation. Improper installation can compromise the overall stability and safety of the pole. Furthermore, if the pole needs to be relocated or repaired, disassembly is equally difficult, easily damaging components and increasing repair costs and time. Summary of the Invention

[0015] Preferably, the retaining disc pushes the triangular plate to move when being placed on the inner wall of the circular groove, so as to extend the embedded extension rod and increase the stability after embedding.

[0016] Preferably, the end of the limiting rod passes through the end wall of the second rectangular groove and is inserted into the inner wall of the limiting hole, and the inner diameter of the limiting hole is matched with the designed outer diameter of the limiting rod.

By installing the anti-collapse structure (I), which uses the plug-in rod on the delay plate to pass through the through-hole (I) of the pre-embedded plate and the through-hole (II) of the outer ring plate of the pole body, the delay plate, pre-embedded plate, and pole body are tightly connected into a single unit, effectively preventing the pole body from collapsing due to loose welds. In complex and changing outdoor environments, poles are constantly subjected to wind, rain, and possible external forces, which may cause welds to loosen. The anti-collapse structure (I) provides additional support for the pole through mechanical connection, greatly enhancing the stability of its overall structure and ensuring the safe operation of the power grid.

[0020] 2. By installing a second anti-fall structure, a fixed block is welded to the periphery of the pole body and a pull wire is installed. The end of the pull wire is connected to the placement block on the embedded plate through a detachable component. This further prevents the main body of the pole from falling and enhances the stability of the pole. When the pole is subjected to strong external forces such as strong winds and earthquakes and tends to fall, the pull wire can exert a pulling effect, dispersing and offsetting some of the external force, preventing the pole from further tilting. This provides a second line of defense against falling, significantly improving the pole's ability to resist falling in extreme situations.

[0021] 3. By providing a quick-disassembly assembly, a limit socket on the inner wall of the circular groove, and an operable limit rod structure composed of a spring and a sliding sleeve on the retention plate, the retention plate and embedded column can be easily separated for transportation and quickly installed and connected. During transportation, the retention plate can be easily separated from the embedded column by operating the sliding plate to retract the limit rod into the rectangular groove, facilitating separate transportation and reducing transportation space and difficulty. At the installation site, the retention plate is placed in the circular groove, and the limit rod automatically pops out and inserts into the limit socket under the action of the spring, achieving a quick connection, greatly improving installation efficiency and reducing installation costs.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Example, see Figure 1-8, an anti-falling electric pole of an electric power grid, comprising an embedded part and an electric pole body 2. The embedded part comprises an embedded plate 1, and the electric pole body 2 is connected to the embedded plate 1 by fixed welding. A circular groove 3 is provided on the lower end surface of the embedded plate 1, and a retention plate 4 is placed on the inner wall of the circular groove 3, and an embedded column 5 is fixedly installed on the lower end surface of the retention plate 4; in order to prevent the electric pole body 2 from falling due to loosening of the welding joint between the embedded plate 1 and the electric pole body 2, an anti-falling structure 1 is provided between the embedded plate 1, the electric pole body 2 and the retention plate 4; in order to further prevent the electric pole body 2 from falling, an anti-falling structure 2 is provided between the embedded plate 1 and the electric pole body 2; in order to strengthen the embedded stability of the embedded plate 1, a reinforcement mechanism is connected to the lower end surface of the embedded plate 1; in order to facilitate the separation and transportation of the retention plate 4 and the embedded column 5, a quick disassembly assembly is connected between the embedded plate 1 and the circular groove 3.

[0026] Furthermore, the anti-collapse structure includes a plug-in rod 6 fixedly mounted on the upper surface of the delayed payment tray 4, and an annular plate 8 fixedly mounted on the periphery of the pole body 2. A through-hole 1 7 is provided on the surface of the embedded tray 1, and the through-hole 1 7 is connected to the circular groove 3 to allow the plug-in rod 6 to pass through. A through-hole 2 9 is provided on the surface of the annular plate 8, so that the plug-in rod 6 can be inserted into through-hole 2 9 after passing through through-hole 1 7. After the pole body 2 and the embedded tray 1 are welded, the plug-in rod 6 is sequentially inserted through through-hole 1 7 and into through-hole 2 9, connecting the delayed payment tray 4, the embedded tray 1, and the pole body 2 into a single entity, effectively preventing the pole body 2 from collapsing due to loose welds.

[0027] Furthermore, the second anti-collapse structure includes a fixing block 25 welded to the periphery of the pole body 2, and a placement groove 27 defined in the upper surface of the embedded plate 1. A pull wire 26 is fixedly mounted on the fixing block 25, the end of which is fixedly connected to a placement block 29. The placement groove 27 and the placement block 29 are connected by removable components. The pull wire 26 further connects the pole body 2 to the embedded plate 1 through the fixing block 25 and the placement block 29. When the pole body 2 is subject to external forces and tends to topple, the pull wire 26 acts as a pull, further preventing the pole body 2 from toppling and enhancing the pole's stability.

[0028] Furthermore, the reinforcement mechanism includes a rectangular groove 10 formed on the lower surface of the embedded plate 1, and a strip-shaped receiving groove 11 formed on the inner wall of the rectangular groove 10. A fixing rod 12 is fixedly connected between the end walls of the strip-shaped receiving groove 11. A spring 13 is sleeved around the outer periphery of the fixing rod 12. One end of the spring 13 is fixedly connected to the end wall of the strip-shaped receiving groove 11, and the other end is fixedly connected to one end surface of a sliding sleeve 14. The outer periphery of the fixing rod 12 is slidably sleeved by the sliding sleeve 14, and the sliding sleeve 14 is slidably connected to the inner wall of the strip-shaped receiving groove 11. A triangular plate 15 is fixedly connected between the two sliding sleeves 14, and the triangular plate 15 is slidably connected to the inner wall of the rectangular groove 10. One end surface of the triangular plate 15 is fixedly connected to the embedded extension rod 16; when the embedded plate 1 is embedded in the ground, the underground environment exerts a force on the triangular plate 15, pushing the sliding sleeve 14 to slide on the fixed rod 12, compressing the spring 13, and extending the embedded extension rod 16, thereby increasing the contact area and grip of the embedded plate 1 with the ground, thereby strengthening the embedded stability of the embedded plate 1 and improving the overall anti-dumping ability of the utility pole.

[0029] Furthermore, the quick-release assembly includes a stopper hole 17 defined in the inner wall of the circular groove 3, a rectangular groove 18 defined in the lower surface of the retention tray 4, and a strip-shaped receiving groove 19 defined in the inner wall of the rectangular groove 18. A fixing rod 20 is fixedly connected between the end walls of the strip-shaped receiving groove 19. A spring 21 is sleeved around the outer periphery of the fixing rod 20. One end of the spring 21 is fixedly connected to the end wall of the strip-shaped receiving groove 19, and the other end is fixedly connected to one end surface of a sliding sleeve 22. The outer periphery of the fixing rod 20 is slidably sleeved by a sliding sleeve 22, which is slidably connected to the inner wall of the strip-shaped receiving groove 19. A sliding plate 23 is fixedly connected between the two sliding sleeve blocks 22, and the sliding plate 23 is slidably connected to the inner wall of the rectangular groove 18. The surface of the sliding plate 23 is fixedly connected to the limiting rod 24; during transportation, the sliding plate 23 can be operated to retract the limiting rod 24 into the rectangular groove 18, so that the delayed plate 4 and the embedded plate 1 are separated for easy transportation; during installation, the delayed plate 4 is placed in the circular groove 3, and the limiting rod 24 pops out under the action of the spring 21 and is inserted into the limiting socket 17, so that the delayed plate 4 and the embedded plate 1 are quickly connected, thereby improving installation efficiency.

[0030] Furthermore, the disassembly and assembly components include placing the placement block 29 into the placement groove 27 during installation, rotating the fastening screw 30 so that its threaded section is screwed into the threaded hole 28, and fixing the placement block 29 in the placement groove 27 to achieve the connection between the pulling wire 26 and the embedded plate 1; during disassembly, rotating the fastening screw 30 in the opposite direction to disengage it from the threaded hole 28, and then removing the placement block 29, which is convenient for inspection or replacement of the pulling wire 26; opening a threaded hole 28 on the inner bottom wall of the placement groove 27, and threading the fastening screw 30 on the surface of the placement block 29, and the threaded section of the fastening screw 30 passes through the placement block 29 and is threadedly connected to the inner wall of the threaded hole 28.

[0031] Furthermore, when the payment disc 4 is placed on the inner wall of the circular groove 3, the payment disc 4 pushes the triangular plate 15, causing the sliding sleeve 14 to slide on the fixed rod 12, compressing the spring 13, and thereby extending the embedded extension rod 16; after the embedded extension rod 16 is extended, the contact area and grip of the embedded disc 1 with the ground are increased, effectively improving the stability after embedment, enhancing the overall anti-toppling ability of the electric pole, and ensuring the safe operation of the power grid.

[0032] Furthermore, the end of the limiting rod 24 passes through the end wall of the rectangular groove 18 and is inserted into the inner wall of the limiting hole 17, and the inner diameter of the limiting hole 17 is adapted to the designed outer diameter of the limiting rod 24; this adaptation design enables the limiting rod 24 to be tightly inserted into the limiting hole 17, ensuring the firmness of the connection between the retention plate 4 and the embedded plate 1, and is not easy to loosen during transportation and installation, thereby improving the stability of the entire anti-fall pole structure.

[0033] Furthermore, one end of the spring 13 is fixedly connected to the end wall of the strip-shaped placement groove 11, and the other end of the spring 13 is fixedly connected to one end surface of the sliding sleeve block 14; when the triangular plate 15 is subjected to an external force to push the sliding sleeve block 14 to compress the spring 13, the spring 13 generates an elastic force. After the external force disappears, the elastic force of the spring 13 can push the sliding sleeve block 14 to reset, thereby restoring the triangular plate 15 and the embedded extension rod 16 to their initial state, ensuring that the reinforcement mechanism can work normally and enhancing the embedded stability of the embedded plate 1.

[0034] Furthermore, one end of the spring 21 is fixedly connected to the end wall of the strip-shaped placement groove 219, and the other end of the spring 21 is fixedly connected to one end surface of the sliding sleeve block 22; when the sliding plate 23 is operated to retract the limiting rod 24 into the rectangular groove 218, the sliding sleeve block 22 compresses the spring 21; when it is necessary to connect the delay disk 4 and the embedded disk 1, the elastic force of the spring 21 pushes the sliding sleeve block 22 to reset, so that the limiting rod 24 pops out and is inserted into the limiting socket 17, thereby realizing quick connection and facilitating the disassembly and transportation of the delay disk 4 and the embedded column 5.

[0035] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
