Description

Technical Field

[0001] This utility model belongs to the field of pole equipment technology, specifically relating to an impact-resistant pole. Background Technology

[0002] Traditional power line poles are typically columnar structures made of a single material (such as concrete or steel), secured by foundations buried deep underground. This pole design provides good support for power lines under normal climatic and geological conditions, ensuring the stability and safety of power transmission. However, when faced with extreme natural disasters (such as mudslides), traditional pole structures often exhibit significant vulnerability. Pole made of a single material (such as concrete) is prone to brittle fracture under strong impact, while steel poles, although more resilient, are more expensive and susceptible to corrosion.

[0003] Traditional utility poles (such as those made of steel, concrete, and wood) are mostly designed to withstand external forces such as wind and snow loads. However, for natural disasters like debris flows, which have large-scale kinetic energy, impact force, and mud and sand particles, the combined force of boulders, soil, and water flow in a debris flow can easily break the poles. Summary of the Invention

[0004] This invention addresses the problem that traditional single-material utility poles have poor impact resistance and toughness, making them prone to breakage in the face of extreme natural disasters such as mudslides. It provides an impact-resistant utility pole by adding a layer structure with strong impact resistance to the outside of the traditional concrete pole, effectively improving the pole's toughness and impact resistance.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An impact-resistant utility pole includes a pole body installed on the ground and a support platform below the ground. The pole body is fixedly mounted on the support platform and is tapered. The pole body comprises, from the inside out, a concrete column, an upper waterproof layer, a rubber inner core layer, a first reinforcing layer, a steel reinforcement support layer, a second reinforcing layer, a first impact-resistant coating, a high-elastic foam layer, and a second impact-resistant coating. The first and second reinforcing layers are both concrete layers with added carbon fiber. Through the multi-layered structure on the outside of the concrete column, the impact resistance and strength of the utility pole in the face of natural disasters are effectively improved.

[0007] The foundation includes a concrete base and a lower waterproof layer that encloses the concrete base. An anti-slip layer is fixedly installed below the foundation. The underground cast-in-place piles are fixedly connected to the foundation to effectively fix the pole. The lower waterproof layer provides waterproofing, and the anti-slip layer increases the friction between the pole and the soil, thereby improving the structural stability of the pole.

[0008] Preferably, the thickness of the upper waterproof layer is 0.5-2mm, the thickness of the rubber inner core layer is 10-30mm, the thickness of the first reinforcing layer and the second reinforcing layer is 40-60mm, wherein the thickness of the carbon fiber is 0.5-2mm, the thickness of the steel reinforcement support layer is 10-30mm, the thickness of the first impact-resistant coating and the second impact-resistant coating is 10-30mm, and the thickness of the high-elastic foam layer is 20-50mm.

[0009] Preferably, the thickness of the lower waterproof layer is 9-11 mm, and the thickness of the anti-slip layer is 5-10 mm.

[0010] Preferably, the impact-resistant pole further includes a collision-resistant assembly fixedly installed on the ground. The collision-resistant assembly includes a buffer spring, a damping element, a first collision-resistant plate, a buffer layer, a second collision-resistant plate, and a protective net. The first collision-resistant plate is sleeved on the outer side of the lower end of the pole body. Multiple buffer springs and damping elements are staggered between the first collision-resistant plate and the pole body. Each buffer spring or damping element is connected to the pole body and the first collision-resistant plate at both ends. A buffer layer is fixedly sleeved on the outer side of the first collision-resistant plate. A second collision-resistant plate is provided on the outer side of the buffer layer. A protective net is provided on the outer side of the second collision-resistant plate. The protective net blocks the impact of boulders and debris on the pole. At the same time, when facing an impact, the multiple buffers such as the buffer layer, damping element, and buffer spring reduce the impact on the pole.

[0011] Preferably, the damping element is a block structure made of rubber, and the buffer layer is an annular plate made of rubber.

[0012] Preferably, a protrusion is provided on one side of the second anti-collision plate, and the protective netting wraps around the second anti-collision plate and the protrusion. The protrusion faces the hillside, so that when facing disasters such as mudslides, mud and water are diverted to both sides of the pole.

[0013] Preferably, both the first and second anti-collision plates are annular plates made of aluminum alloy. Aluminum alloy itself has a certain degree of toughness and can serve as a buffer against impacts.

[0014] Preferably, the protective net is a steel wire mesh.

[0015] The beneficial effects of this utility model through the above technical solution are as follows:

[0016] 1. This utility model, through the multi-layer structure set outside the concrete column, effectively ensures the buffering of external impacts when facing extreme natural disasters such as mudslides, and effectively improves the strength and impact resistance of the pole.

[0017] 2. This utility model prevents groundwater from eroding and damaging the concrete base by setting a waterproof layer outside the concrete base, and prevents the pole from sliding under impact by setting an anti-slip layer below the waterproof layer. Combined with the underground cast-in-place piles to fix the pile cap, it improves the structural stability of the pole and reduces the risk of the pole tilting, sliding or collapsing under external impact.

[0018] 3. This utility model effectively reduces the damage to utility poles caused by external impacts such as mudslides by setting up anti-collision components, especially the damage to the concrete column. When faced with external impact, firstly, two aluminum alloy anti-collision plates absorb the impact and guide it to both sides of the pole. Secondly, a rubber buffer layer further absorbs the external impact. Furthermore, damping blocks and buffer springs ensure that the external impact is further buffered and absorbed before reaching the concrete column. At the same time, the elasticity of the buffer springs is used to reset and restore the utility pole when the impact is weak, effectively improving the impact resistance of the utility pole in extreme natural disasters such as mudslides.

[0019] 4. This utility model further blocks the impact of rocks or debris on the utility pole by setting a protective net on the outside of the second anti-collision plate.

[0020] 5. When the impact-resistant pole of this utility model is installed, a protrusion can be provided on the second anti-collision plate as needed. The protrusion is integrally formed with the second anti-collision plate and faces the direction of the impact, that is, the upstream direction of natural disasters such as hillsides. When facing mudslides, the protrusion and the anti-collision components work together to better guide the mudslides to both sides of the pole and reduce the impact on the pole.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] like Figures 1-4 As shown, this embodiment provides an impact-resistant pole, including a pole body 1 set on the ground and a foundation below the ground. The pole body 1 is fixedly set on the foundation, and the foundation is fixedly connected to the underground reinforced concrete piles to ensure the stability of the pole foundation and secure fixation. The pole body 1 is a tapered pole body, that is, the cross-section of the pole body 1 increases from top to bottom, which not only optimizes the material distribution but also improves the load-bearing capacity of the pole body 1. The piles penetrate deep into the ground, forming a strong bond and a stable support system with the soil. The pole body 1 includes, from the inside out, a concrete column 11, an upper waterproof layer 12, a rubber inner core layer 13, a first reinforcing layer 14, a steel reinforcement support layer 15, a second reinforcing layer 16, a first impact-resistant coating 17, a high-elastic foam layer 18, and a second impact-resistant coating 19.

[0030] The concrete column 11 is a reinforced concrete structure, which serves as the main body of the utility pole and is used to support the power lines.

[0031] The upper waterproof layer 12 is a polyurethane layer or an epoxy resin layer, and the thickness of the upper waterproof layer 12 is 0.5-2mm. Its main function is to protect the internal structure (i.e., the concrete column 11) and prevent water penetration.

[0032] The rubber inner core layer 13 has a thickness of 10-30mm and serves as an intermediate layer to provide cushioning and shock absorption.

[0033] Both the first reinforcing layer 14 and the second reinforcing layer 16 are concrete layers with added carbon fibers. The thickness of the first reinforcing layer 14 and the second reinforcing layer 16 is 40-60mm, and the thickness of the carbon fibers is 0.5-2mm. The carbon fibers added to the concrete can effectively enhance the strength and stiffness of the structure.

[0034] The thickness of the steel reinforcement support layer 15 is 10-30mm, and the steel reinforcement support layer 15 is also provided with reinforcing ribs. The steel reinforcement support layer 15 is mainly used to support the structure.

[0035] The first impact-resistant coating 17 and the second impact-resistant coating 19 have a thickness of 10-30 mm, providing further cushioning and protection for the pole and preventing external impacts from affecting the internal structure.

[0036] The thickness of the high-elastic foam layer 18 is 20-50mm, providing good impact absorption and adaptability for the pole structure.

[0037] The foundation includes a concrete base 21 and a lower waterproof layer 22 enclosing the concrete base 21. The concrete base 21 is a reinforced concrete structure and is fixedly connected to the pile below. The lower waterproof layer 22 is made of corrosion-resistant and wear-resistant materials. Specifically, the lower waterproof layer 22 is a waterproof mortar layer, a waterproof concrete layer, or an asphalt waterproof membrane layer. The thickness of the lower waterproof layer 22 is 9-11mm, specifically 10mm.

[0038] An anti-slip layer 23 is fixedly installed under the foundation. The anti-slip layer 23 is made of a material with high strength and good friction performance. Specifically, the anti-slip layer 23 is a rubber pad layer and a polymer cement mortar layer. The thickness of the anti-slip layer 23 is 5-10mm. It is mainly used to increase the friction between the foundation and the soil and prevent the pole from slipping under external impact.

[0039] The impact-resistant pole also includes a collision-resistant assembly 3 fixedly installed on the ground. The collision-resistant assembly includes a buffer spring 31, a damping element 32, a first collision-resistant plate 33, a buffer layer 34, a second collision-resistant plate 35, and a protective net 36. A first collision-resistant plate 33 is fitted onto the outer side of the lower end of the pole body 1. Multiple buffer springs 31 and damping elements 32 are staggered between the first collision-resistant plate 33 and the pole body 1. The damping element 32 is a block-shaped structure made of rubber. When facing external impacts, the buffer springs 31 and damping elements 32 can absorb and mitigate part of the impact acting on the pole body 1. Furthermore, the compressed buffer springs 31 provide a buffer to the outside of the pole body 1. The reverse force helps the outer structure to reset. Each of the buffer springs 31 or damping elements 32 is connected to the rod body 1 and the first anti-collision plate 33 at both ends. A buffer layer 34 is fixedly sleeved on the outside of the first anti-collision plate 33. A second anti-collision plate 35 is provided on the outside of the buffer layer 34. Both the first anti-collision plate 33 and the second anti-collision plate 35 are annular plates made of aluminum alloy. The aluminum alloy plate itself has a certain toughness and provides a certain buffering and impact resistance to absorb external impacts. The buffer layer 34 is an annular plate made of rubber. On this basis, the buffer layer 34 further absorbs external impacts and effectively protects the rod body 1.

[0040] The second anti-collision plate 35 is provided with a protective net 36 on its outer side to further block the impact of rocks and debris in the mudslide on the power pole. The protective net is made of corrosion-resistant and wear-resistant materials. Specifically, the protective net 36 is a wire mesh or a synthetic fiber mesh.

[0041] A protrusion 37 is provided on one side of the second anti-collision plate 35. The protective net 36 wraps around the second anti-collision plate 35 and the protrusion 37. By making the protrusion 37 face the upstream direction such as the hillside, it can guide the mudslide to both sides and separate it when facing natural disasters such as mudslides, effectively protecting the power pole and reducing the impact on the power pole.

[0042] In use, this utility model effectively absorbs external impacts through the two-layer anti-collision plate, rubber buffer layer, damping block, and buffer spring in the anti-collision component, reducing impact damage to the pole. Multiple layers are installed on the outside of the pole to improve its strength, impact resistance, and waterproofing. The pole is fixed by underground cast-in-place piles and a foundation, and the foundation is protected by a lower waterproof layer and an anti-slip layer. This effectively improves the pole's impact resistance and adaptability under extreme natural disasters such as mudslides, enhancing its ability to withstand different natural disasters and reducing the risk of the pole tipping over, sliding, or breaking when subjected to external impacts.

[0043] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
