Description

Technical Field

[0001] This invention relates to the field of cement pole technology, and more particularly to a tapered cement pole with a prestressed steel rod anchor head. Background Technology

[0002] Conical concrete poles, due to their lightweight structure, excellent bending and torsional resistance, small footprint, and suitability for complex outdoor terrain, have become core support components for overhead power transmission and communication signal transmission lines. They are widely used in urban and rural power grid construction, communication base station erection, and other engineering fields. To further improve the crack resistance, load-bearing capacity, and long-term service stability of concrete poles, prestressing technology is widely used in the production and manufacturing of conical concrete poles. By arranging prestressed steel bars inside the pole body and tensioning and anchoring them, prestress is formed in the concrete of the pole body, which counteracts the tensile stress generated by the concrete pole under bending and tension conditions (such as strong winds, icing, and conductor tension). This reduces concrete cracking at the source and extends the service life of the concrete pole. Among them, the anchor head at the end of the prestressed steel bar is the core key component of the prestressing system. Its main function is to realize the tension of the prestressed steel bar, reliable anchoring, and effective transmission of tension to the concrete pole body. It is the basis for ensuring that the prestressed steel bar and concrete work together and maintaining the prestress of the pole body. The existing tapered cement poles have not been fitted with appropriate bird-proofing mechanisms after installation. Outdoor birds are prone to nesting and perching on the top of the cement poles, around the anchor heads, and at the crossarm connection points. Bird droppings can easily corrode the metal parts of the anchor heads, prestressed steel bars, and the concrete of the pole body, accelerating the corrosion failure of the anchor structure and the damage to the pole body. Furthermore, the dead branches and debris left by birds to build nests can easily cause short circuits in power lines and interference with communication signals, becoming a major safety hazard for the operation of overhead lines. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a solution to the problems described in the background art.

[0004] Technical solution: A tapered cement pole with a prestressed steel bar anchor head, comprising a pole body, wherein a prestressed steel bar is disposed inside the pole body, the top end of the prestressed steel bar extends to the top of the pole body and is integrally formed with an anchor head body, and a cover plate is disposed on the upper surface of the pole body and outside the anchor head body, and a protective mechanism is disposed on the upper surface of the cover plate. Mounting blocks are fixedly connected to the left and right sides of the outer side wall of the rod. Mounting rods are provided inside the two mounting blocks. Wire racks are fixedly connected to the front and rear surfaces of the two mounting rods. The outer side walls of the two mounting rods are fixedly connected to the two mounting blocks by bolts.

[0005] Furthermore, a base is fixedly connected to the lower surface of the rod, and multiple through-holes are provided on the upper surface of the base.

[0006] Furthermore, the upper surface of the rod is fixedly connected with a plurality of pre-embedded bolts, the top ends of the plurality of pre-embedded bolts extending to the outer side of the cover plate, and the outer side walls of the plurality of pre-embedded bolts are threaded with locking nuts.

[0007] Furthermore, the protective mechanism includes a support column, a rotating rod fixedly connected to the lower surface of the support column, the lower surface of the rotating rod being rotatably connected to the upper surface of the cover plate via a rotating shaft, a rotating bearing being provided on the outer side wall of the rotating rod and located on the upper surface of the cover plate, a connecting plate being fixedly connected to the outer side wall of the support column, and reflective lenses being embedded on both sides of the plurality of connecting plates.

[0008] Furthermore, a sealing gasket is fixedly connected to the lower surface of the cover plate.

[0009] Furthermore, a control gear is provided on the inner upper surface of the cover plate. The center of the upper surface of the control gear is fixedly connected to the center of the lower surface of the rotating rod. A movable circular plate is rotatably connected to the inner upper surface of the cover plate and to the right of the control gear via a rotating shaft. A shaft is fixedly connected to the center of the lower surface of the movable circular plate. A motor is fixedly connected to the bottom end of the shaft. A support plate is fixedly connected to the bottom end of the motor. The right side of the support plate is fixedly connected to the interior of the cover plate. Multiple toothed blocks are fixedly connected to the outer wall of the movable circular plate.

[0010] Furthermore, a second mounting block is fixedly connected to the rear surface of the rod, and a second mounting rod is fixedly connected to the interior of the second mounting block by bolts. A photovoltaic panel is fixedly connected to the rear end of the second mounting rod by bolts.

[0011] Beneficial effects: By adopting an integrated molding design for the prestressed steel bar and the anchor head, this invention effectively strengthens the connection strength between the prestressed steel bar and the anchor head, avoids the slippage problem that is prone to occur in traditional split connections, ensures the stable transmission of prestress in the pole, reduces prestress loss from the source, fully utilizes the prestressing effect of the prestressed steel bar on the pole, significantly improves the crack resistance and bending resistance of the tapered cement pole, and makes the pole adaptable to the complex stress conditions of outdoor overhead lines; This invention achieves a secure lock between the cover plate and the rod body through the cooperation of pre-embedded bolts and locking nuts. With the sealing gasket on the lower surface of the cover plate, the connection gap between the cover plate and the rod body can be completely sealed to form a tight sealing and protective structure. This effectively prevents rainwater, moisture, dust and corrosive media from seeping in, avoiding corrosion failure of the anchor head body and the top of the prestressed steel rod. At the same time, the cover plate forms an external shield for the anchor head body, reducing the contact of external debris and bird droppings, ensuring the long-term stability of the prestressed anchoring system and improving the outdoor service durability of the rod body. The protective mechanism of this invention adopts a dual-drive design of natural wind rotation and electric motor drive. Natural wind can directly drive the connecting plate and reflective lens to rotate, while the motor drives the protective mechanism to rotate intermittently through the meshing of the gear block and the control gear. The dual-drive mode ensures that the reflective lens always maintains a dynamic reflective effect, which is not limited by outdoor wind conditions, and achieves all-weather efficient bird deterrence. It fundamentally prevents birds from staying and nesting around the anchor head, and eliminates safety hazards such as short circuits caused by birds. This invention integrates the prestressed anchoring structure, sealing and protection structure, dual-drive bird-proof mechanism, power line erection structure, photovoltaic power supply structure, and foundation fixing structure into a unified design. The layout of each structural component is reasonable and the functions are coordinated, making full use of the space resources of the pole and eliminating structural interference issues. All detachable connection parts are bolted, making installation and maintenance convenient. The entire device can achieve core functions such as bird protection and anchoring protection without external power supply. While ensuring the structural performance of the tapered cement pole foundation and the function of power line erection, it simultaneously achieves multiple effects such as efficient bird protection, energy saving and environmental protection, and sealing and protection. It comprehensively improves the outdoor service safety, structural reliability, working condition adaptability, and practicality of cement poles, meeting the long-term service requirements of overhead power lines.

[0014] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1-4As shown, a conical cement pole with a prestressed steel rod anchor head is provided, including a pole body 1, a prestressed steel rod 2 is provided inside the pole body 1, the top of the prestressed steel rod 2 extends to the top of the pole body 1 and is integrally formed with an anchor head body 3, a cover plate 4 is provided on the upper surface of the pole body 1 and outside the anchor head body 3, and a protective mechanism 5 is provided on the upper surface of the cover plate 4; mounting blocks 12 are fixedly connected to the left and right sides of the outer side wall of the pole body 1, mounting rods 6 are provided inside the two mounting blocks 12, and wire frames 7 are fixedly connected to the front and rear surfaces of the two mounting rods 6; the outer side walls of the two mounting rods 6 are respectively fixedly connected to the two mounting blocks 12 by bolts. The prestressed steel rod 2 embedded inside the pole 1 provides prestress to the pole 1, ensuring its crack and bending resistance. The top of the prestressed steel rod 2 extends above the pole 1 and is integrally formed with the anchor head body 3, strengthening the connection between the two, avoiding slippage and prestress loss, and ensuring stable transmission of prestress to the pole 1. The cover plate 4 set on the upper surface of the pole 1 outside the anchor head body 3 seals the gap between the top of the pole 1 and the anchor head body 3. The protective mechanism 5 on the upper surface of the cover plate 4 forms a double layer of protection with the cover plate 4, providing all-round protection for the anchor head body 3 and the top of the prestressed steel rod 2, blocking external media and bird droppings from corroding, preventing rust failure, and avoiding line damage caused by bird nesting. Potential hazards: Mounting blocks 12, fixed to the left and right outer walls of pole 1, provide stable support for mounting pole 6. Mounting pole 6 is embedded in mounting blocks 12, and the wire racks 7 on its front and rear surfaces are used to securely support overhead wires. Mounting pole 6 and mounting blocks 12 are detachably connected by bolts, which not only ensures that pole 1 is subjected to uniform force and avoids eccentric deformation, but also facilitates the disassembly and fine-tuning of mounting pole 6 and wire rack 7, adapting to the needs of different specifications of lines. All components work together to integrate the functions of prestressed anchoring, protection, and wire rack 7 installation, taking into account the structural stability of pole 1, the durability of anchoring and protection, the convenience of wire rack 7 installation, and the need for outdoor bird protection, thereby improving the overall reliability and adaptability of the device.

[0016] like Figure 1 As shown, a base 8 is fixedly connected to the lower surface of the rod 1, and a plurality of through-holes 9 are provided on the upper surface of the base 8. The base 8 effectively increases the contact area between the pole 1 and the mounting base, preventing the pole 1 from sinking or tipping due to outdoor stress, and significantly improving the overall installation and support stability of the pole 1. The upper surface of the base 8 has multiple through-hole fixing holes 9, which can be used to fit anchor bolts and other fasteners, so as to achieve a firm lock between the base 8 and the concrete foundation, ground and other mounting bases. The distribution design of multiple fixing holes 9 makes the connection between the base 8 and the base surface more uniform, further enhancing the installation and fixing effect of the pole 1.

[0017] like Figure 4As shown, a plurality of pre-embedded bolts 10 are fixedly connected to the upper surface of the rod body 1, and the top ends of the plurality of pre-embedded bolts 10 extend to the outer side of the cover plate 4 respectively. Locking nuts 11 are threadedly connected to the outer side walls of the plurality of pre-embedded bolts 10. A sealing gasket 13 is fixedly connected to the lower surface of the cover plate 4. Multiple pre-embedded bolts 10 fixed on the upper surface of the rod 1 extend to the outer side of the cover plate 4, and the locking nuts 11 threaded to the outer side of each pre-embedded bolt 10 can be tightened to securely lock the cover plate 4 to the rod 1. The even distribution of multiple pre-embedded bolts 10 balances the force on the cover plate 4, effectively preventing the cover plate 4 from loosening and shifting under strong winds and vibrations outdoors, ensuring the protective stability of the cover plate 4. The sealing gasket 13 fixed on the lower surface of the cover plate 4 can fit tightly against the upper surface of the rod 1 after the locking nuts 11 are tightened, completely sealing the connection gap between the cover plate 4 and the rod 1, preventing rainwater, moisture, dust, etc. from seeping into and contacting the anchor head body 3 and the top of the prestressed steel rod 2 from the gap, further improving the sealing and protection effect of the anchoring structure, preventing the internal metal parts from rusting and failing, and ensuring the long-term stability of the prestressed system.

[0018] like Figure 2 and Figure 3 As shown, the protective mechanism 5 includes a support column 501, a rotating rod 502 is fixedly connected to the lower surface of the support column 501, the lower surface of the rotating rod 502 is rotatably connected to the upper surface of the cover plate 4 through a rotating shaft, a rotating bearing 503 is provided on the outer side wall of the rotating rod 502 and located on the upper surface of the cover plate 4, a connecting plate 504 is fixedly connected to the outer side wall of the support column 501, and reflective mirrors 505 are embedded on both sides of the multiple connecting plates 504. The protective mechanism 5 can be driven directly by the outdoor natural wind to drive the connecting plate 504 to continuously rotate the entire protective mechanism 5 around the rotating shaft. The dynamic reflective lens 505 can enhance the visual bird deterrence effect, fundamentally preventing birds from staying and nesting around the anchor head body 3. The reflective lens 505 adopts an embedded installation method, which is firmly connected and not easy to fall off in strong wind conditions. The configuration of the rotating bearing 503 not only ensures the smooth rotation of the protective mechanism 5, but also improves its durability in outdoor service. The entire protective mechanism 5 has a simple and reasonable structural design, which uses natural wind to achieve dynamic bird deterrence, energy saving and environmental protection. While achieving efficient bird deterrence, it further enhances the protective effect on the anchor head body 3 and the top of the prestressed steel rod 2.

[0019] like Figure 3 and Figure 4As shown, a control gear 506 is provided on the inner upper surface of the cover plate 4. The center of the upper surface of the control gear 506 is fixedly connected to the center of the lower surface of the rotating rod 502. A movable circular plate 507 is rotatably connected to the inner upper surface of the cover plate 4 and located to the right of the control gear 506 via a rotating shaft. A shaft 508 is fixedly connected to the center of the lower surface of the movable circular plate 507. A motor 509 is fixedly connected to the bottom end of the shaft 508. A support plate 510 is fixedly connected to the bottom end of the motor 509. The right side of the support plate 510 is fixedly connected to the inside of the cover plate 4. Multiple tooth blocks 511 are fixedly connected to the outer wall of the movable circular plate 507. The motor 509 drives the movable circular plate 507 to rotate. Through the meshing transmission of the gear block 511 and the control gear 506, the rotating rod 502, the support column 501, and multiple connecting plates 504 are indirectly driven to rotate intermittently. This achieves dynamic rotation of the reflective lens 505 on the connecting plate 504 without relying on outdoor natural wind. Even in windless or lightly windy conditions, the controllable drive of the motor 509 allows the reflective lens 505 to continuously reflect light dynamically, creating a continuous visual bird-repelling effect. This completely prevents birds from adapting to static reflection and staying or nesting around the anchor head body 3. The indirect rotation design ensures efficient bird protection while reducing the operating losses of the transmission components of the protective mechanism 5, extending its outdoor service life. Meanwhile, the transmission structure, such as the motor 509 and control gear 506, is built into the cover plate 4, which is sealed by the cover plate 4 and the sealing gasket 13 to effectively prevent the infiltration of rainwater, moisture, and dust, preventing the transmission components and motor 509 from rusting and malfunctioning, and ensuring the long-term stable operation of the electric drive mode. Through the ingenious design of the dual-drive rotation structure, it takes into account both natural energy saving and active control, so that the bird protection effect of the protective mechanism 5 is not limited by the natural environment, achieving all-weather efficient bird protection.

[0020] like Figure 1 , Figure 2 and Figure 4 As shown, a second mounting block 14 is fixedly connected to the rear surface of the rod body 1, and a second mounting rod 15 is fixedly connected to the interior of the second mounting block 14 by bolts. A photovoltaic panel 16 is fixedly connected to the rear end of the second mounting rod 15 by bolts. The mounting block 2 14, fixed to the rear surface of pole 1, makes reasonable use of the unused space behind pole 1, avoiding the area where the front power line frame 7 is laid, thus not affecting the installation of overhead power lines and subsequent operation and maintenance. At the same time, it provides a stable installation support foundation for the mounting pole 2 15. The mounting pole 2 15 and the mounting block 2 14, as well as the mounting pole 2 15 and the photovoltaic panel 16, are detachably fixed with bolts. This ensures the firmness of the connection structure and facilitates the on-site installation, disassembly, and flexible fine-tuning of the installation angle of the photovoltaic panel 16. It can adapt to different regional lighting conditions and improve the photovoltaic light energy reception efficiency. The photovoltaic panel 16 can convert outdoor solar energy into electrical energy, specifically providing power to the motor 509 in the protection mechanism 5. This enables the motor 509 to operate in a solar-powered self-sufficient mode, eliminating the need for external mains power, saving energy and protecting the environment. It completely solves the problem of outdoor power supply for the motor 509, ensuring the stable operation of the dual-drive bird-proof structure in outdoor conditions without external power supply, and improving the outdoor adaptability, practicality, and energy efficiency of the device.
