Description

Technical Field

[0001] This invention relates to the field of power tower technology, specifically to a power transmission line tower and a power transmission line tower system. Background Technology

[0002] In long-distance power transmission networks, transmission line towers serve as the core supporting structure, playing a crucial role in fixing transmission conductors and ensuring the safe and stable operation of the lines. Their performance directly affects the reliability, economy, and environmental adaptability of power transmission. Some transmission line towers are widely used in overhead transmission lines, mainly bearing the support function of vertical and lateral loads on the power lines.

[0003] Chinese Patent Application No. 202010628601.2 discloses a single-circuit transmission line tower and a transmission line tower system. Belonging to the field of transmission line technology, the single-circuit transmission line tower includes: a tower body, a curved arm, a grounding frame, conductor crossarms, and additional crossarms; the tower body is buried in the ground, and the curved arm is connected to the tower body; the conductor crossarms include a first conductor crossarm, a second conductor crossarm, and a third conductor crossarm connected in sequence, with the second conductor crossarm connected to the curved arm; the grounding frame includes at least one first grounding frame and a second grounding frame, with the first grounding frame connected to the first conductor crossarm and the second grounding frame connected to the third conductor crossarm; the additional crossarms are connected to either the first or third conductor crossarm, and a ground wire is installed on the additional crossarms at the drilling and crossing points of the tower, while no ground wire is installed on the additional crossarms at non-drilling and crossing points. However, during use, the conductors may sway under wind force, easily leading to loosening of the connections.

[0004] Furthermore, with prolonged use, the fasteners of the wires gradually lose their fixing effectiveness due to wear, corrosion, or the swaying of the wires. This causes the wires to gradually loosen within the fasteners due to external forces, and may even lead to loosening at the connection between two wires, thus affecting the stability of power transmission. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a transmission line tower and transmission line tower system that effectively limits the swing amplitude of the power line, prevents excessive swing from causing the power line fixing point to loosen, and effectively ensures that the power line is fixed for a long time, avoiding the reduction of the fixing effect of the power line due to wear and aging of fasteners. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a transmission line tower, comprising a tower body and a support assembly;

[0007] The support assembly includes a support frame located on the side of the tower body. Insulators are hinged to both ends of the support frame via hinge seats. A connecting seat is provided at the end of the insulator away from the support frame. An arc-shaped surface is opened at the end of the connecting seat. Wires are installed on both sides of the support frame, and the opposite ends of the wires on both sides are connected by the connecting assembly.

[0008] It also includes a fixing component, which includes a support slot and a fixing slot at the bottom of the support slot;

[0009] The top of the support slot is provided with a detection component, which includes a roller, and a quarter area of ​​the circumferential surface of the roller is provided with teeth in a circumferential array.

[0010] The top of the support slot is provided with a limiting component near the detection component. The limiting component includes an inclined movable seat. The top side of the movable seat near the roller is provided with equally spaced drive tooth grooves, and the bottom side of the movable seat away from the roller is provided with equally spaced limiting tooth grooves.

[0011] The limiting component also includes two limiting teeth respectively located on the side and bottom of the arc-shaped surface, and the limiting teeth correspond to the limiting tooth grooves.

[0012] Preferably, the tower body has a conical structure, and a base is provided at the bottom of the tower body;

[0013] The support components are staggered on the top side of the tower.

[0014] Preferably, the end of the support slot is hinged to the connecting seat via a hinge shaft, the hinge shaft coincides with the center of the arc surface, and the wire passes through the grooves inside the support slot and the fixing slot in sequence.

[0015] The side of the fixing slot is provided with a fastener. The fastener is a U-shaped structure and wraps around the wire. Both ends of the fastener pass through both sides of the fixing slot, and both ends of the fastener are threaded with nuts.

[0016] Preferably, the two ends of the roller are rotatably connected to the top of the support groove via a support plate, the roller is equipped with a rotation sensor, and the bottom of the roller abuts against the wires inside the support groove.

[0017] Preferably, the movable seat passes through the through groove formed by the junction of the support slot and the fixed slot;

[0018] The movable seat has a side seat on its side, which corresponds to the support on the top surface of the support groove seat, and a spring rod is provided between the side seat and the support.

[0019] Preferably, the limiting component further includes a wedge block, which is disposed on the bottom side of the movable seat near the roller. The bottom of the wedge block abuts against the wire, the top width of the wedge block is greater than the bottom width, and the wedge block is made of insulating elastic material.

[0020] Preferably, the connecting assembly includes two correspondingly arranged card holders, which are engaged with the ends of the wires on both sides by correspondingly arranged card slots, and the two card holders are connected by screws.

[0021] Preferably, the connecting assembly further includes an electrically telescopic part, the fixed end of which is disposed on the bottom surface of the end of the support frame via an insulating seat, and the bottom telescopic end of the electrically telescopic part is fixedly connected to the card seat via an insulating rod.

[0022] The present invention also discloses a power transmission line tower system, which includes the power transmission line towers described above.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. During use, if the wires become loose due to wear of fasteners, a slight displacement will occur, causing the detection roller in contact with them to rotate. The rotation sensor on the roller will immediately capture this signal and send the warning information to the maintenance personnel via wireless communication, thus realizing the early detection of potential risks and providing a basis for timely maintenance.

[0025] 2. When the power line swings under the action of wind, it will cause the entire fixed component to rotate slightly around the hinge point. Once the swing amplitude is too large, the limiting tooth groove on the movable seat linked with the fixed component will mesh with the limiting tooth on the tower body. Under the damping action of the spring rod, the swing amplitude is physically limited to prevent the connection from loosening due to excessive swing.

[0026] 3. When the loosening of the wire continues to worsen, the roller will drive the movable seat to move diagonally downward after rotating to a specific angle. The wedge block at the bottom of the movable seat will then press the wire downward. The greater the loosening of the wire, the greater the clamping force generated by the wedge block, thereby automatically counteracting the loosening trend and converting the kinetic energy generated by the loosening into additional fastening force.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figure 1-5 The present invention provides a technical solution: a transmission line tower, including a tower body 1 and a support component 2, wherein the tower body 1 has a conical structure and a base 101 is provided at the bottom of the tower body 1.

[0036] Specifically, the support component 2 is used to support the wire 205, and the base 101 is used to be pre-embedded and fixed in the foundation pit. The foundation pit is constructed using a multi-head water-jet drilling rig.

[0037] Support components 2 are staggered on the top side of the tower body 1. The support components 2 include support frames 201 on the side of the tower body 1. Insulators 203 are hinged to both ends of the support frame 201 via hinge seats 202. A connecting seat 204 is provided at the end of the insulator 203 away from the support frame 201. An arc-shaped surface is opened at the end of the connecting seat 204. Wires 205 are correspondingly mounted on both sides of the support frame 201. The opposite ends of the wires 205 on both sides are connected by a connecting component 4.

[0038] Specifically, under the traction of the wires 205 on both sides, the insulators 203 on both sides are close to horizontal. After the wires 205 on both sides pass through the fixing components 3 on both sides respectively, the opposite ends of the wires 205 on both sides are suspended. After the connecting component 4 connects the opposite ends of the wires 205 on both sides, they are still in a suspended state rather than a tensioned state.

[0039] It also includes a fixing component 3, which includes a support slot 301. The end of the support slot 301 is hinged to the connecting seat 204 via a hinge shaft. The hinge shaft coincides with the center of the arc surface. A fixing slot 302 is provided at the bottom of the support slot 301. The wire 205 passes through the grooves inside the support slot 301 and the fixing slot 302 in sequence. A fastener 303 is provided on the side of the fixing slot 302. The fastener 303 has a U-shaped structure and wraps around the wire 205. The two ends of the fastener 303 pass through the two sides of the fixing slot 302 respectively. Nuts are threaded onto both ends of the fastener 303.

[0040] Specifically, after the wire 205 passes through the support slot 301 and the fixing slot 302 in sequence, the fastener 303 is inserted through the fixing slot 302, so that the U-shaped fastener 303 is tightly fastened to the outside of the wire 205. Nuts are screwed onto both ends of the fastener 303 and tightened, so that the fastener 303 is tightly pressed against the outside of the wire 205, thereby fixing the wire 205.

[0041] The top of the support slot 301 is provided with a detection component, which includes a roller 307. The two ends of the roller 307 are rotatably connected to the top of the support slot 301 through the support plate 306. The roller 307 is provided with a rotation sensor. The bottom of the roller 307 abuts against the wire 205 inside the support slot 301.

[0042] Specifically, the roller 307 rotates when it comes into contact with the wire 205 and the wire 205 becomes loose. At this time, the rotation sensor can detect the rotation of the roller 307. The rotation sensor transmits the signal to the external terminal through the wireless communication module to detect the loosening of the wire 205 in a timely manner, which facilitates subsequent continuous follow-up and maintenance. The rotation sensor is preferably a rotary encoder.

[0043] A limiting component is provided at the top of the support slot 301 near the detection component. The limiting component includes an inclined movable seat 309. The movable seat 309 passes through the through groove formed by the junction of the support slot 301 and the fixed slot 302. A side seat 311 is provided on the side of the movable seat 309. The side seat 311 corresponds to the support 310 provided on the top surface of the support slot 301. A spring rod 312 is provided between the side seat 311 and the support 310. Limiting tooth grooves 314 are provided at equal intervals on the bottom side of the movable seat 309 away from the roller 307.

[0044] The limiting component also includes two limiting teeth 315 respectively located on the side and bottom of the arc-shaped surface, with the limiting teeth 315 corresponding to the limiting tooth grooves 314.

[0045] Specifically, in the initial state, there is a gap between the limiting tooth 315 and the limiting tooth groove 314. When the spring rod 312 is subjected to compressive and tensile forces, it will generate reverse elastic resistance. When the end of the wire 205 swings around the center of the arc surface at the end of the connecting seat 204, it will drive the movable seat 309 to rotate around the center of the arc surface. When the swing amplitude is about to exceed the limit, the limiting tooth groove 314 will mesh with the limiting teeth 315 on both sides, which will drive the movable seat 309 to move obliquely. Under the action of the elastic resistance of the spring rod 312, the oblique movement distance of the movable seat 309 can be limited, thereby limiting the swing amplitude of the wire 205.

[0046] The connecting component 4 includes two corresponding card holders 401. The two card holders 401 are connected to the ends of the wires 205 on both sides through corresponding card slots. The two card holders 401 are connected by screws 402. After the wires 205 on both sides are connected and connected through the card holders 401, they are in a suspended state.

[0047] In use, firstly, after the tower body 1 is assembled, the wire 205 is passed through the support slot 301 and the fixing slot 302 of the fixing component 3. The wire 205 is pressed and fixed by the U-shaped fastener 303 and nut. The support slot 301 is hinged to the connecting seat 204 through the hinge shaft. After the wires 205 on both sides pass through the fixing components 3 on both sides, the ends of the wires 205 on both sides are connected by the card seat 401 and screw 402 of the connecting component 4. At this time, the opposite ends of the wires 205 on both sides form a hanging state, which prevents the wires 205 on both sides from applying an initial tension to the card seat 401 and causing the wires 205 to detach from the card seat 401.

[0048] After prolonged use, if the fastener 303 wears or corrodes, resulting in a decrease in the fixing effect, the wire 205 will loosen slightly. When the wire 205 moves slightly due to the loosening, it will slide slightly away from the insulator 203 along the inner groove of the support slot 301, thereby driving the roller 307 to rotate. The rotation sensor detects the signal and sends it to the external terminal through the wireless communication module to realize early loosening warning for continuous monitoring.

[0049] In addition, when the wire 205 swings under the action of wind, the wire 205 drives the support slot 301 to swing, and the support slot 301 drives the movable seat 309 to rotate around the hinge axis. When the swing amplitude of the support slot 301 approaches the limit, the limiting tooth groove 314 engages with the limiting teeth 315 on the side and bottom respectively, so that the movable seat 309 moves obliquely. The elastic resistance of the spring rod 312 limits the movement distance of the movable seat 309, thereby physically limiting the swing amplitude of the wire 205 and preventing the connection from loosening.

[0050] Furthermore, a quarter of the circumferential surface of the roller 307 is provided with a circumferential array of teeth 308, and the movable seat 309 is provided with equally spaced drive tooth grooves 313 on the top side of the roller 307.

[0051] Specifically, in the initial state, the gear teeth 308 correspond to the drive tooth groove 313, and there is a preset distance between the gear teeth 308 and the drive tooth groove 313. After the roller 307 rolls at a preset angle, the gear teeth 308 mesh with the drive tooth groove 313.

[0052] The limiting component also includes a wedge block 316, which is located on the bottom side of the movable seat 309 near the roller 307. The bottom of the wedge block 316 abuts against the wire 205. The top width of the wedge block 316 is greater than the bottom width. The wedge block 316 is made of insulating elastic material.

[0053] Specifically, when the movable seat 309 moves diagonally downward, it drives the wedge block 316 to move. Due to the structural characteristics of the wedge block 316 itself, as the movable seat 309 moves, the squeezing force of the wedge block 316 on the wire 205 gradually increases.

[0054] When the wire 205 becomes slightly loose over a long period of time, the roller 307 continues to rotate. After the roller 307 rotates to a preset angle, the gear teeth 308 begin to mesh with the drive tooth groove 313. As the roller 307 continues to rotate towards the movable seat 309, the roller 307 drives the movable seat 309 to move obliquely downward through the gear teeth 308. The movable seat 309 drives the wedge block 316 to move obliquely downward. The wedge block 316 can continuously apply a squeezing force to the wire 205 to prevent the wire 205 from loosening further. That is, the looser the wire 205, the greater the squeezing force of the wedge block 316 on the wire 205. This converts the driving force generated by the loosening of the wire 205 into the squeezing force of the wedge block 316 on the wire 205, effectively preventing the wire 205 from becoming loose.

[0055] Meanwhile, as the gear teeth 308 mesh with the drive tooth groove 313, the gear teeth 308 play a positioning role for the movable seat 309. At this time, when the wire 205 swings excessively, the limiting tooth 315 will not be able to drive the movable seat 309 to move after meshing with the limiting tooth groove 314. At this time, the elastic limiting of the movable seat 309 by the spring rod 312 turns into the hard limiting of the movable seat 309 by the gear teeth 308, thereby further limiting the swing amplitude of the wire 205 and preventing the swing of the wire 205 from accelerating the loosening of the wire 205 itself.

[0056] Furthermore, as the wires 205 loosen, the opposite ends of the wires 205 on both sides will move towards one side of the fixing slot 302, thereby increasing the pressure of the ends of the wires 205 on the retaining bracket 401, causing the ends of the wires 205 to gradually detach from the retaining bracket 401.

[0057] Therefore, the connecting assembly 4 also includes an electric telescopic part 404. The fixed end of the electric telescopic part 404 is provided on the bottom surface of the end of the support frame 201 through an insulating seat 405, and the bottom telescopic end of the electric telescopic part 404 is fixedly connected to the card seat 401 through an insulating rod 403.

[0058] Specifically, after the two card holders 401 engage and fix the ends of the wires 205 on both sides, the ends of the wires 205 on both sides are in a suspended state. The extension and retraction of the electric telescopic part 404 drives the card holders 401 to move up and down through the insulating seat 405 to adjust the suspension height of the ends of the wires 205.

[0059] In use, when the rotation sensor detects the rotation of the roller 307, it actively determines that the wire 205 has become loose. At this time, the electric telescopic part 404 is activated to drive the card holder 401 to move upward. By reducing the hanging height of the end of the wire 205, sufficient looseness is given to the wire 205 to prevent the wire 205 from pulling on the card holder 401 and causing the wire 205 to gradually fall off the card holder 401, thus affecting the stability of power transmission.

[0060] Example 2

[0061] This embodiment provides a construction method for the foundation pit described in Embodiment 1 to improve the efficiency of the pre-embedded construction of the foundation 101. Specifically:

[0062] Step 1: Complete the review and design briefing of the basic construction drawings, the construction plan has been prepared and the review process has been completed, and the corresponding multi-head water drill and related equipment have been equipped.

[0063] Step 2: Construction personnel participate in training on regulations, management systems, tower construction drawings, and work instructions. After passing the exam, they are certified to work. All construction personnel undergo physical examinations and receive safety technical briefings.

[0064] Step 3: Construction tools and equipment should be selected strictly according to the configuration list, and arranged in an orderly manner on site, neatly placed, and clearly labeled. The tools and equipment should be tested and qualified, and maintenance should be completed.

[0065] Step 4: Clean up the work surface: Remove vegetation, obstacles and other debris from the work surface and make the work surface as flat as possible;

[0066] Step 5: Excavate the foundation: Excavate the foundation according to the construction drawings. The excavation area should meet the space requirements for drilling within the foundation. Depending on the site conditions, an excavator or a manual pneumatic pick can be used to excavate the foundation.

[0067] Step 6, Center Hole Laying Out: Use a total station for positioning and laying out, and lay out the center hole with reference to the hole center to ensure that the dimensions between holes are accurate;

[0068] Step 7: Equipment system in place;

[0069] Step 8, Equipment Assembly: The connections of all parts of the drilling rig should be firm, and the hoses should be bent appropriately. During the assembly process, protective measures should be taken for easily deformable parts such as hydraulic cylinders, drill rods, and drill frames to prevent deformation.

[0070] Step 9: Mark the center of the center hole on the rock surface of the working face with a clear mark: According to the position of the drilling, first stabilize the drill frame base, then install the support leg assembly, support the drill frame and gradually adjust the verticality, then install the pads on the two legs, and tighten the support leg locking nuts and the drill frame base positioning plate nuts.

[0071] Step 10, Drilling:

[0072] Before drilling, check whether the drilling rig is installed correctly and stably, whether all connections are secure, whether the control handle is flexible and reliable, and whether all moving parts rotate freely.

[0073] For the construction of the center hole, a center hole drilling machine is used to drill the center hole and take the core. The hole depth is about 700mm.

[0074] Positioning the multi-head water drill: Insert the bottom center rod of the multi-head water drill into the completed center hole, and place the multi-head water drill flat;

[0075] Step 11, Free Face Construction: Based on the pile foundation cross-section diagram, use a drilling rig to drill holes in batches along the outline to quickly form the free face;

[0076] Step 12, core extraction: Use core extractors to extract the core from the free face;

[0077] Step 13, Core breaking: Place a hydraulic core breaker on one side of the concentric circle, and use the lateral expansion force of the hydraulic core breaker to push the central rock mass up until it breaks completely.

[0078] Step 14, Core Removal with a Crane: Use a crane to remove the separated core samples;

[0079] Step 15: Leveling the bottom of the pit: Construction workers go down into the pit and use tools such as pneumatic picks to level the bottom of the pit;

[0080] Step 16: Repeat the above steps to construct the next depth until the designed depth is reached;

[0081] Step 17: After completing the drilling operation, stop drilling, lift the drill bit upwards, and after cleaning, cover the hole with a covering material to prevent foreign objects from falling in and subsequent construction pollution;

[0082] Step 18: Technicians observe and record changes in the rock strata. If the geological conditions are found to be inconsistent with the data provided in the design, the machine should be stopped and the design department should be notified for handling.

[0083] Step 19, Hole Formation Quality Inspection: After the foundation pit drilling is completed, immediately inspect the hole formation quality, check the diameter, depth, and verticality to ensure that the error is within the specified error range. After the inspection is qualified, use a sealing material to seal the hole to prevent debris from falling into the hole.

[0084] Step 20: Place the prefabricated steel cage into the hole according to the construction drawings. Use the small crane attached to the multi-head water drill to lift the steel cage into the hole as a whole. Since the steel cage is long and requires to be lifted into place in one go, attention should be paid to controlling the deformation of the steel cage during lifting and relocation. After the steel cage is put into the hole, check the placement position according to the design requirements and make a record. Temporary fixing measures should be taken after the steel cage is put into the hole to prevent the steel cage from falling due to its own weight or moving upwards during concrete pouring and causing misalignment.

[0085] Step 21: Move the equipment to the next location for construction: Based on the layout location, move the multi-head water-jet drilling rig to the next positioning point and carry out construction according to the above steps;

[0086] Step 22: Pour concrete into the hole according to the construction drawings: The strength of the mortar or concrete used for pouring shall be in accordance with the design requirements. The water-cement ratio of the mortar or concrete shall be determined by the test. The raw materials shall be measured during mixing, and the water-cement ratio and slump shall be strictly controlled.

[0087] Before grouting, the rock walls of the hole should be moistened with water, and water should not accumulate inside the hole to ensure the adhesion between the mortar (concrete) and the hole wall.

[0088] During grouting, it is necessary to compact the concrete in layers. Too much should not be poured at once to prevent stones from getting stuck and creating gaps. During compaction, care should be taken to prevent the position of reinforcing bars or anchor bolts from shifting.

[0089] The amount of concrete or mortar poured into the hole shall not be less than the value specified in the construction drawings;

[0090] Step 23: After the pile foundation has solidified, cast the pile cap and foundation columns on top of it: After the pile foundation concrete has solidified, cast the pile cap reinforcement and anchor bolts on top of it according to the construction drawings, and at the same time, make the formwork. The formwork and its support should have sufficient load-bearing capacity, rigidity and stability to withstand the weight, lateral pressure and construction load of the poured concrete.

[0091] Step 24, Foundation Formwork Removal and Backfilling: The formwork can only be removed after the concrete reaches the specified strength requirements. After the formwork is removed, the foundation area should be backfilled and leveled. When backfilling, care should be taken to ensure that the surface and edges of the foundation and columns are not damaged, and to avoid collision with the anchor bolts and insert angle steel to prevent loosening.

[0092] Step 25, Construction Completion and Site Cleanup: After construction is completed, clean up the construction site to ensure that all materials are used up and the site is clean.

[0093] Step 26: When building tower 1, connect and fix the base 101 to the completed foundation.
