Description

Technical Field

[0001] This invention relates to the technical field of concrete pole production, specifically to an earthquake-resistant and overturning-resistant concrete pole and its application method. Background Technology

[0002] Concrete poles are the basic supporting components of urban and rural power distribution networks and rural power transmission lines. They are used in the open and buried for a long time and are susceptible to external forces such as strong winds, earthquakes, rain erosion, and foundation settlement.

[0003] While existing wind- and earthquake-resistant concrete utility poles have solved the current problems, they rely solely on simple sliders, single-set shock-absorbing springs, and supports for cushioning at the base. They lack multi-layered composite earthquake-resistant support structures. During earthquakes, the springs are prone to fatigue failure due to reciprocating alternating vibrations, the sliders easily get stuck in their fixed slots, and cannot continuously unload force. The protective plate only provides elastic cushioning on one side, and there is no surrounding ring-shaped anti-overturning reinforcement base. Under lateral strong winds and transverse seismic loads, the force is uneven, and the pole is prone to unilateral displacement. The gaps between the multi-stage springs and sliding components are large, and after long-term vibration, the gaps continue to widen, resulting in a high risk of pole tilting and overturning under earthquake or strong wind conditions. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing wind-resistant and earthquake-resistant concrete utility poles have a high risk of tilting and overturning under earthquake or strong wind conditions, and to propose a production device for composite molded ring concrete utility poles.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a seismic and overturning resistant concrete pole, comprising a pole body and a connecting box, wherein the inner wall of the pole body is threadedly connected to the connecting box, the upper end of the connecting box is fixedly connected to a connecting frame, a solar panel is fixedly installed on the surface of the connecting frame, and a bird deterrent is installed on the surface of the connecting frame. The solar panel and the bird deterrent are integrated on the connecting frame to achieve photovoltaic self-powered supply and bird protection for the line. A reinforcement mechanism is connected to the outer wall of the lower end of the pole body.

[0006] Furthermore, the reinforcement mechanism includes an upper seat, the inner wall of which is inserted into the pole body, and the lower end of the upper seat is fixedly connected to the lower seat. The upper and lower seats wrap around the bottom of the pole to form a composite base. The outer wall of the lower seat is fixedly connected to a slope strip, which increases the contact area between the base and the backfill soil and improves the soil gripping force.

[0007] Furthermore, the inner wall of the upper seat is inserted into the insertion rod, the outer wall of the insertion rod is inserted into the pole body, and a support mechanism is connected to the middle of the pole body.

[0008] This feature: The insertion pole passes through the upper base and the pole body, locking the base and pole body together to prevent relative slippage between the base and pole body; the support mechanism provides diagonal tensile support to resist lateral wind force and seismic load.

[0009] Furthermore, the support mechanism includes a lower connecting ring, the inner wall of which is fixedly connected to the pole body, the inner wall of which is threadedly connected to the fixing seat by bolts, and the lower end of the fixing seat is fixedly connected to the support rod.

[0010] This feature involves a lower connecting ring that clamps the middle of the pole, and a support rod that is diagonally supported to the bottom upper seat via a fixed base, forming a triangular stable support system that significantly improves the pole's lateral impact and seismic resistance.

[0011] Furthermore, the end of the support rod is threadedly connected to the upper seat via bolts, and both ends of the support rod are respectively connected to the lower connecting ring and the upper seat, making disassembly and assembly convenient.

[0012] Furthermore, the upper end of the pole body is fixedly connected to the upper connecting ring, which provides a stable installation point for the power transmission crossarm. The inner wall of the upper connecting ring is threadedly connected to the crossarm by bolts. The bolt connection facilitates the disassembly and maintenance of the crossarm and is suitable for various cable laying requirements.

[0013] Furthermore, the outer wall of the upper base is fixedly connected to the fence, and the fence and gate are arranged around the base of the pole to prevent pedestrians and livestock from touching it. The outer wall of the fence is equipped with a gate.

[0014] Furthermore, a storage battery is installed on the inner wall of the connecting box. The solar panel absorbs light energy and converts it into electrical energy, which is stored in the storage battery to continuously power the bird repeller. The input end of the storage battery is electrically connected to the solar panel, and the output end of the storage battery is electrically connected to the bird repeller, which automatically repels birds around the clock and eliminates the risk of short circuits when birds build nests.

[0015] The method of using earthquake-resistant and overturning-resistant concrete poles is characterized by: S1. Hoist the prefabricated utility pole body into place, and attach the upper seat of the reinforcement mechanism to the lower section of the utility pole body. The lower seat and the upper seat are integrally formed. The lower seat has an integral slope strip. Insert the plug rod through the upper seat and the utility pole body to lock the upper seat and the pole body to prevent relative slippage. Fix the lower connecting ring in the middle of the pole body. Assemble the fixing seat with bolts. Connect the two ends of the support rod to the fixing seat and the upper seat respectively to form a triangular bracing structure to improve the lateral impact resistance. S2. Install a fence and gate on the outside of the upper seat, put a storage battery inside the connecting box, thread the connecting box at the top of the pole, fix the connecting frame on the top, install solar panels and bird deterrents on the frame, complete the circuit wiring, so that the solar panels, storage batteries and bird deterrents form a power supply circuit, and finally fix the connecting ring on the upper part of the pole body, tighten the bolts on the crossarm, and the entire pole assembly is completed. When backfilling the base, the slope strip increases the soil interlocking area.

[0016] The present invention proposes an earthquake-resistant and overturning-resistant concrete pole, which has the following advantages: the base is composed of an upper seat and a lower seat through a bottom reinforcement mechanism. The slope strip on the outer wall of the lower seat increases the contact area with the soil cover, thereby improving the foundation grip. The inserted pole penetrates and locks the pole body and the base to prevent slippage. The lower connecting ring and support rod of the middle support mechanism form a triangular brace, which effectively offsets the lateral bending moment caused by strong winds and earthquakes. The multiple structures work together to distribute the external load, greatly improving the overall stability and making it less prone to overturning. It is suitable for areas prone to strong winds and earthquakes, and the structure is easy to disassemble, assemble, and maintain. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-7In this embodiment, an earthquake-resistant and overturning-resistant concrete pole includes a pole body 1 and a connecting box 2. The inner wall of the pole body 1 is threadedly connected to the connecting box 2. The upper end of the connecting box 2 is fixedly connected to the connecting frame 3. A solar panel 4 is fixedly installed on the surface of the connecting frame 3. A bird deterrent 5 is installed on the surface of the connecting frame 3. A reinforcement mechanism 6 is connected to the outer wall of the lower end of the pole body 1.

[0020] This embodiment uses a 12m prestressed concrete tapered utility pole body 1, with a bottom outer diameter of 420mm and a top outer diameter of 190mm. An M48 internal threaded sleeve is pre-installed at the top of the inner wall of the pole, and the sleeve is embedded in the concrete to a depth of not less than 120mm to ensure sufficient tensile bearing capacity when threadedly assembled with the connecting box 2. The connecting box 2 is made of hot-dip galvanized steel sheet by stamping, with an outer wall thickness of 4mm. An internal sealed cavity is reserved for housing the battery 13. The lower end of the connecting box 2 is integrally machined with an external thread section, and the effective thread engagement length is ≥80mm. After being screwed into the internal threaded sleeve at the top of the pole, it can be locked a second time by tightening the lock nut to prevent the thread from loosening under long-term vibration. It is fully suitable for long-term outdoor use of outdoor power distribution networks.

[0021] The reinforcement mechanism 6 includes an upper seat 601, the inner wall of which is inserted into the pole body 1. The lower end of the upper seat 601 is fixedly connected to the lower seat 602, and the outer wall of the lower seat 602 is fixedly connected to the slope strip 603. The slope strip 603 increases the contact area between the lower seat and the surrounding backfill soil. Both the upper seat 601 and the lower seat 602 are precast reinforced concrete integral casting components. When they are cast, the integral connecting steel bars are reserved, eliminating the need for secondary welding and splicing on site, which greatly shortens the construction time of the foundation pit. The inner diameter of the upper seat 601 matches the outer diameter of the lower section of the pole body 1. Four axial limiting protrusions are evenly arranged on the inner wall of the inner hole. The protrusions are 15mm high and 20mm wide, corresponding one-to-one with the axial grooves reserved on the outer wall of the pole body, realizing the connection between the upper seat 601 and the pole body 1. The circumferential limit prevents the base from rotating circumferentially relative to the pole during installation and earthquake vibration. The lower base 602 is shaped like an inverted trapezoid, with 8 sets of slope strips 603 evenly embedded along the circumference of the outer wall. Each slope strip 603 is 600mm long, 100mm thick, and 200mm high. The outer surface of the slope strip 603 is processed with concave and convex anti-slip teeth with a tooth depth of 8mm. After the foundation pit is backfilled and compacted, the teeth can be embedded into various conventional foundation soil layers such as silty clay, sand, and gravelly soil, which greatly improves the interlocking friction between the base and the soil and solves the defects of insufficient soil holding force of traditional smooth base and pole tilting after foundation settlement.

[0022] The bottom reinforcement mechanism consists of an upper seat 601 and a lower seat 602 forming a base. The outer wall slope strip 603 of the lower seat 602 increases the contact area with the soil cover, improving the foundation grip. The insertion rod 7 penetrates and locks the rod body 1 and the base to prevent slippage. The lower connecting ring 801 and the support rod 803 of the middle support mechanism form a triangular brace, which effectively offsets the lateral bending moment caused by strong winds and earthquakes. The multiple structures work together to distribute the external load, greatly improving the overall stability and making it less prone to overturning. It is suitable for areas prone to strong winds and earthquakes, and the structure is easy to disassemble and maintain.

[0023] The inner wall of the upper seat 601 is inserted into the insertion rod 7, and the outer wall of the insertion rod 7 is inserted into the pole body 1. A support mechanism 8 is connected to the middle of the pole body 1. Four sets of through insertion rod holes with a diameter of 32mm are symmetrically opened radially at corresponding positions on the lower section of the pole body 1 and the upper seat 601. The insertion rod 7 is made of φ30 high-strength 45# solid round steel, with M28 fastening threads machined at both ends. During assembly, the insertion rod 7 passes horizontally through the upper seat 601 and the pole body 1, and flat washers, spring washers, and double locking nuts are installed at both ends respectively. The double nuts are locked in opposite directions to prevent vibration and loosening. With a single-strand shear capacity ≥120kN, the four sets of inserts are arranged in a cross-shaped symmetrical pattern, capable of simultaneously bearing horizontal and vertical loads. The concrete poles are rigidly locked to the bottom reinforced base as a whole. When an earthquake generates lateral reciprocating shear force or strong winds generate lateral thrust, relative slippage and separation between the poles and the base are completely avoided, eliminating the risk of pole detachment and overturning from the source. Compared with the traditional method of fixing the base by simply wrapping and attaching it, the structural connection reliability is improved by more than 60%.

[0024] The support mechanism 8 includes a lower connecting ring 801. The inner wall of the lower connecting ring 801 is fixedly connected to the pole body 1. The inner wall of the lower connecting ring 801 is threadedly connected to the fixing seat 802 by bolts. The lower end of the fixing seat 802 is fixedly connected to the support rod 803. The support rod 803 forms an oblique support for the middle part of the pole body 1, transferring the lateral load to the bottom reinforcement base, further improving the stability of the overall structure. The end of the support rod 803 is threadedly connected to the upper seat 601 by bolts. The lower connecting ring 801 adopts a two-half split ring structure. A flange connecting plate is installed at the joint of the two halves of the ring. The flange plate has 6 sets of M18 bolt holes. During assembly, it wraps around the middle of the pole body 1 at a height of 2.8m above the ground. Tightening the flange bolts ensures a tight clamping between the ring and the pole body. A 5mm thick rubber anti-slip pad is pasted on the inner wall of the ring. The surface of the pad is covered with a granular anti-slip layer to increase the friction between the ring and the concrete pole body, preventing the ring from sliding up and down or circumferentially along the pole body when the support is under stress. Four installation positions are evenly reserved on the outer circumference of the lower connecting ring 801. Each position has a welded fixing seat 802 with an internal M20 threaded hole. The support rod 803 is made of φ76 hot-dip galvanized seamless steel pipe with a wall thickness of 5mm. Connecting flanges are welded to both ends. The upper flange is locked to the fixing seat 802 with M20 high-strength bolts, and the lower flange extends to the upper seat 601. The sidewalls are pre-installed with threaded supports, which are also fastened with bolts. The angle between a single support rod and the ground is controlled between 40° and 45°. The four support rods are symmetrically arranged around the ring body to form a four-sided closed triangular stable support system. When strong winds or earthquakes generate lateral bending moments acting on the upper part of the pole, the support rods can directly transmit most of the horizontal lateral force to the bottom reinforced base, and then the base slope strip 603 disperses it to the surrounding soil, which greatly reduces the bending stress borne by the pole body 1 and avoids cracking and breakage failure in the middle of the pole.

[0025] The upper end of the pole body 1 is fixedly connected to the upper connecting ring 9. The inner wall of the upper connecting ring 9 is threadedly connected to the crossarm 10 by bolts. The upper connecting ring 9 also adopts a two-half clamp structure and is installed 1.2m below the top of the pole. The inner side of the clamp is also covered with anti-slip rubber pads. The outer wall of the clamp has three sets of transverse installation threaded holes, which can be adapted to single-circuit, double-circuit, and triple-circuit galvanized crossarms 10 of different specifications. The crossarm 10 is made of ∠80×8 equal angle steel, and the length can be freely selected according to the line span. The crossarm and the upper connecting ring 9 are fastened with M16 bolts. The bolts are equipped with spring anti-loosening washers. When the line is modified or the crossarm is rusted and replaced in the future, it can be disassembled separately by simply loosening the bolts. There is no need to remove the upper components of the pole as a whole, making maintenance and operation convenient.

[0026] The outer wall of the upper seat 601 is fixedly connected to the fence 11. The outer wall of the fence 11 is equipped with a gate 12. Eight galvanized pre-embedded nuts are embedded in the top outer edge of the upper seat 601. The fence 11 is a rectangular protective frame welded from φ40 galvanized round tubes. Through holes are opened at corresponding positions on the bottom uprights of the frame, and the frame is fixed to the upper seat 601 by bolts. The overall height of the fence 11 is 1.2m. An openable gate 12 is set in the middle of the frame. The gate is equipped with a spring lock. It is locked and isolated from the base area during daily use to prevent livestock from rushing and pedestrians from climbing and bumping into the pole base. The gate is 800mm wide, and maintenance personnel can directly open the gate to enter the base area without removing the entire fence, which facilitates regular tightening and maintenance of the battery, base connection structure, and support rod bolts.

[0027] A storage battery 13 is installed on the inner wall of the connecting box 2. The input end of the storage battery 13 is electrically connected to the solar panel 4. The solar panel 4 converts light energy into electrical energy and stores it in the storage battery 13, realizing the self-powered power supply of the device without the need for external mains power, thus reducing wiring costs. The output end of the storage battery 13 is electrically connected to the bird repeller 5. The connecting box 2 has a waterproof isolation chamber inside, and the chamber is filled with polyurethane sealant. A 12V 20Ah lead-acid maintenance-free battery 13 is placed inside the chamber, and the terminals at both ends of the battery are equipped with waterproof insulating sleeves. The connecting frame 3 is an L-shaped galvanized bracket with a 30° tilt angle to adapt to the outdoor sunlight angle. A single 40W monocrystalline silicon solar panel 4 is laid flat on the top surface of the bracket. The solar panel wires pass through a waterproof wiring connector and are connected to the battery charging circuit. The bird repeller 5 is a dual-mode bird repeller device using ultrasonic waves and strobe lights. The rated operating voltage is 12V. It is fixed to the side of the connecting frame 3. During the day, it is powered by the solar panel in real time, and at night, it is continuously discharged by the battery. It repels birds around the clock and prevents birds from nesting on the crossarm and pole top, which could cause short circuits and discharge faults. The entire power supply circuit is completely independent and does not require an external municipal power line. It can be used directly in mountainous areas and areas without power supply.

[0028] Instructions for using earthquake-resistant and overturning-resistant concrete poles: Assembly process: The prefabricated pole body 1 is hoisted into place. The upper seat 601 of the reinforcement mechanism 6 is fitted onto the lower section of the pole body 1. The lower seat 602 is integrally formed with the upper seat 601. The lower seat 602 has an integral slope strip 603. Insert the insert rod 7 through the upper seat 601 and the pole body 1 to lock the upper seat 601 and the pole body 1 together, preventing relative slippage. Fix the lower connecting ring 801 in the middle of the pole body 1. Assemble the fixing seat 802 with bolts. Connect the two ends of the support rod 803 to the fixing seat 802 and the upper seat 601 respectively, forming a triangular bracing structure to improve lateral impact resistance. Install the fence 11 and gate 12 on the outside of the upper seat 601. Insert the battery 13 into the connecting box 2. Thread the connecting box 2 onto the top of the pole body. Fix the connecting frame 3 on top. Install solar panels 4 on the frame. With the bird deterrent device 5, complete the circuit wiring to form a power supply circuit with the solar panel 4, the battery 13, and the bird deterrent device 5. Finally, fix the connecting ring 9 on the upper part of the pole body 1, tighten the bolts on the crossarm 10, and the entire pole assembly is completed. When backfilling the base, the slope strip 603 increases the soil interlocking area.

[0029] Step 1: Foundation Pit Pretreatment and Base Compaction. Before construction, use a total station to locate the center point of the pole, excavate the foundation pit, and construct the pit to a depth of 2.2m according to the specifications for 12m concrete poles. Add a 300mm layer of 20cm thick crushed stone cushion at the bottom of the pit, and compact it in layers using a plate compactor, ensuring a compaction degree of ≥93%. If the site is low-bearing-capacity foundation such as silt or soft soil, add an additional 300mm thick reinforced concrete leveling layer to ensure the 602 base is level after placement, with a horizontal deviation controlled within 1‰ to prevent the pole from naturally tilting later. Step 2: Base Pre-installation and Pole Hoisting Alignment. Beforehand, hoist the upper seat 601 and lower seat 602 as a whole into the gravel cushion layer of the foundation pit. Manually align the center of the base with the line positioning point and use a spirit level to level the base around its perimeter. Use a truck crane to lift the pole body 1 and slowly insert it vertically into the inner hole of the upper seat 601, aligning the pole body with the axial limiting protrusion on the inner wall of the upper seat to ensure no circumferential deviation of the pole body. The verticality of the pole body is calibrated using a theodolite, and the overall tilt error does not exceed 0.5°. Step 3: Insert the pole and lock it into a rigid connection. Align the radial insertion holes reserved in the upper seat 601 and the pole body, and insert the insertion rod 7 into the four sets of symmetrical holes respectively. The two ends of the insertion rod extend out of the base. Insert flat washers and spring anti-loosening washers in sequence, and tighten the double locking nuts. Use a torque wrench to control the tightening torque of the nuts to ≥220N. After all the poles are locked, the pole body and the bottom base form a rigid, non-slip integral whole, eliminating the risk of pole-base separation. Step 4: Assembly of the central triangular support mechanism. Install the two-half lower connecting ring 801 at the pole body position 2.8m above the ground, align the flange mating surface, and tighten the flange bolts evenly to ensure that the ring body and the pole body slide without gaps; assemble the four support rods 803 in sequence, bolt the upper flange to the outer fixing seat 802 of the lower connecting ring, and tighten the lower flange to the threaded support on the side wall of the upper seat 601. Adjust the length of the support rods to make the four rods bear the force evenly, and maintain the angle between each support rod and the ground at 40°-45°. The four-sided triangular support structure is formed simultaneously, forming a closed-loop lateral force system. Step 5: Installation of the bottom protective fence. With the help of the pre-embedded nuts at the top of the upper seat 601, fix the bottom uprights of the fence 11 with bolts, close the gate and lock the buckle. The fence completely covers the base area, isolating the soil, equipment and pedestrians and livestock, while leaving maintenance openings. Step 6: Top electrical and photovoltaic module assembly. Place the battery 13 in the waterproof compartment of the connector box 2, and ensure waterproof protection for the wiring; screw the lower external thread section of the connector box 2 into the upper internal thread sleeve of the pole body 1, and tighten the lock nut after it is in place; fix the connector bracket 3 at the upper end of the connector box 2, install the solar panel 4 at an angle, connect the wires to the battery charging terminal through the waterproof connector, and then connect the battery output cable to the bird deterrent 5 to complete the photovoltaic self-powered circuit construction; finally, install the connector ring 9 below the top of the pole, assemble the crossarm 10 of the corresponding specification according to the line erection requirements, and tighten the bolts to complete the assembly of the entire pole. Step 7: Layered backfilling and compaction of the foundation pit. After all assembly is completed, backfilling of the foundation pit begins. Large stones and construction waste are removed from the backfill soil. Every 300mm thick layer of backfill is compacted in layers using a rammer. After compaction, a 300mm high anti-settlement platform is built above the foundation pit. The outer slope of the platform matches the slope strip 603 below, so that the slope strip is fully embedded in the compacted soil, maximizing the foundation's grip.

[0030] Usage process During line erection, the power transmission cable is fixed to the crossarm 10 of the upper connecting ring 9. In daily operation, the solar panel 4 absorbs sunlight during the day and stores it in the battery 13, continuously powering the bird deterrent 5 to automatically drive away birds and prevent short circuits caused by bird nesting. When encountering lateral loads such as strong winds or earthquakes, the inclined support structure composed of the support rods 803 shares the bending moment of the pole. The upper seat 601 and lower seat 602 at the bottom, combined with the slope strip 603, increase the foundation grip. The insertion rod 7 locks the pole to the base, effectively preventing the pole from tilting or overturning. The fence 11 and gate 12 isolate the base area, preventing pedestrians and livestock from bumping into the pole base. During later maintenance, the gate 12 can be opened to maintain the battery 13, and the support rods 803 and lower connecting ring 801 can be disassembled for separate pole maintenance. The top connecting frame 3 is detachable, facilitating the replacement of the solar panel 4. Along with bird deterrent device 5, this pole features a multi-layered anti-overturning structure that is stable and reliable, and also has the advantages of bird protection and easy maintenance. It is suitable for power distribution network installation in areas prone to earthquakes and with strong winds.

[0031] The daily operation principle of the photovoltaic bird deterrent device: During the day, natural sunlight shines on the solar panel 4, and the light energy is converted into DC power and stored in the battery 13. During periods of sufficient sunlight, the power consumption of the bird deterrent device 5 can be fully met throughout the day. On cloudy days and at night when there is no sunlight, the battery 13 continuously and stably outputs 12V DC power to drive the bird deterrent device 5. The device alternately releases ultrasonic waves and high-frequency flashing lights to stimulate the auditory and visual systems of birds, continuously driving away birds that are perched or nesting. The entire power supply circuit is designed with a fully sealed waterproof design. The waterproof compartment of the connection box 2 and the cable joints are all sealed. There will be no problems with short circuits or water damage to the battery in rainy or frosty weather. The continuous service life in the field can reach more than 5 years. There is no need for manual periodic battery replacement or external power supply, which greatly reduces the operation and maintenance costs of the power distribution network. 2. Strong Wind Resistance and Overturning Resistance Principle: When strong lateral winds continuously act on the pole and crossarm cable, the pole generates an overturning moment that tilts to one side. This moment is distributed in two stages: the first stage is supported by a four-sided triangular support system composed of four symmetrical support rods 803 in the middle, which directly transmits the horizontal lateral tension and thrust to the bottom upper seat 601; the second stage load is transmitted to the integrated lower seat 602, where multiple sets of slope strips 603 on the outer wall of the lower seat are embedded in the compacted backfill soil over a large area. The overturning moment is offset by the soil's own weight and interlocking friction. At the same time, the cross-shaped symmetrically arranged inserts 7 continuously constrain the pole and the base, preventing relative slippage. The synergistic effect of multiple load-bearing structures significantly reduces the bending stress at the pole root. Compared with traditional unsupported smooth base poles, the critical overturning load is increased by more than 70%, and it can withstand the continuous lateral impact of a level 10 gale. 3. Earthquake Reciprocating Load Buffering and Unloading Principle: Earthquakes generate bidirectional vibrations of transverse and longitudinal waves, which create reciprocating alternating shear and torsional loads on concrete poles. Traditional poles rely solely on the base plate for support, making them prone to foundation loosening and pole tilting under repeated vibrations. The triangular bracing structure of this invention decomposes the reciprocating lateral impact force of earthquakes, evenly distributing the alternating load to the surrounding soil. The slope strip 603 of the lower base engages extensively with the soil, suppressing the reciprocating horizontal displacement of the base. The insert 7 rigidly locks the pole to the base, preventing the pole from separating from the base or becoming misaligned under vibration. The shear force borne by the concrete pole itself is significantly reduced, effectively preventing pole cracking and overall collapse after an earthquake. It is suitable for use in power distribution network projects in high seismic-resistant areas with peak ground acceleration of 0.2g and above. 4. Post-Inspection, Disassembly, and Maintenance Principle: All key load-bearing connection points of this invention adopt a bolt-on detachable assembly structure, eliminating on-site welding and permanent fixing components, thus simplifying maintenance operations. ① Base area inspection: Directly open the fence 11 gate without removing the protective structure to visually check whether the locking nuts at both ends of the plug rod and the bolts at the lower end of the support rod are loose, and tighten them with a torque wrench; open the sealing compartment of the connection box 2 to directly remove the battery 13 for charging and replacement.② Inspection of the middle support structure: Loosen the flange bolts of the lower connecting ring 801 to remove the entire support structure. Replace any rusted or deformed support rods individually without hoisting the entire pole. ③ Inspection of the top photovoltaic and line components: Loosen the locking nuts between the connecting box 2 and the top of the pole to disassemble the connecting frame 3, solar panel 4, and bird deterrent 5.

[0032] Loosen the upper connecting ring 9 bolts to disassemble and replace the rusted crossarm 10 separately, adapting to line expansion and renovation needs. All components of the entire set of equipment can be disassembled and replaced individually, eliminating the need to scrap the entire pole, significantly reducing maintenance costs. The entire disassembly and assembly process only requires common power tools such as regular wrenches and torque wrenches, and ordinary distribution network maintenance personnel can complete the operation without special training.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
