Description

Technical Field

[0001] The invention relates to the technical field of electric poles, and in particular to an electric pole which is easy to assemble and erect. Background Art

[0002] The main function of utility poles is to support and fix electric wires to ensure the stable transmission of electricity or communication signals.

[0003] In the prior art, electric poles are usually long pole-shaped structures. For example, a Chinese patent with publication number CN105604374B discloses an electric pole, which includes: a pole body, the pole body including: a first end for erecting electric wires and a second end for burying in the ground; an anti-climbing device fixed between the first end and the second end; the anti-climbing device is located between the midpoint of the pole body and the first end. The electric pole proposed in the above scheme blocks the passage of climbers through the anti-climbing device, which can effectively prevent non-power maintenance personnel from climbing the electric pole. However, when the electric pole proposed in the above scheme is erected, due to the long length of the electric pole, it is usually necessary to rely on a crane to adjust it from a horizontal state to a vertical state. This process requires close cooperation between the crane operator and the ground staff. However, this operation is not only complicated and cumbersome, but also accompanied by a relatively high risk. The weight and volume of the electric pole make it possible to cause accidents in the erection process, such as the tipping of the electric pole and injuries to personnel. In addition, the erection of the electric pole also requires precise positioning and fixing in a pre-dug pit, which further increases the difficulty and danger of the operation.

[0014] As a preferred technical solution of the present invention, the outer peripheral surface of the connecting seat and the inner surface of the connecting tube are in contact with each other.

[0015] The present invention has the following beneficial effects: 1. The utility pole proposed by the present invention is composed of a number of independent and detachable pole bodies, and the adjacent pole bodies are closely connected by connecting units to form a long pole structure. This design replaces the structure of the traditional long pole-shaped utility pole. The design enables each section of the pole body to be independently disassembled and assembled, reduces the weight of a single component and shortens the length, so that the staff can easily lift, lower and accurately adjust the position of the pole body during the erection process. This transformation not only significantly simplifies the erection process of the utility pole and improves work efficiency, but also facilitates the operation of the staff, reduces physical exertion and safety risks. Furthermore, the detachability of the modular pole body brings unprecedented convenience to the storage and transportation of the utility pole. During the transportation stage, the pole body can be compactly stacked, which greatly saves space and reduces logistics costs. During storage, this feature can also be used to achieve efficient management and reduce dependence on storage space. 2. The utility pole design proposed in the present invention ensures the overall stability through lifting and locking after the pole body is assembled. Specifically, the staff uses two first cables to operate the lifting sleeve to move it down along the pole body one by one, and when passing each connection unit, the pressing assembly and the locking assembly on the lifting sleeve accurately complete the locking operation between the connecting tube and the connecting seat. In this process, the movable plate on the lifting sleeve first contacts the locking ring and pushes it down, thereby causing a series of card blocks to be squeezed by the inclined surface and move toward the connecting seat until each card block is accurately inserted into the corresponding card slot. This series of actions not only realizes the rapid and stable connection between the connecting tube and the connecting seat, but also ensures the overall stability of the entire utility pole structure; 3. The utility pole locking mechanism of the present invention realizes a multiple locking effect after the locking ring contacts and securely falls into place, thereby ensuring the overall stability of the utility pole structure. In this process, the locking ring not only causes the card block to be completely inserted into the card slot, thereby realizing a tight connection between the connecting tube and the connecting seat, but also enables the locking block to be retracted into the installation slot by its squeezing effect on the inclined surface of the locking block. After the locking ring is in place, the locking block is precisely ejected and inserted into the groove of the locking ring by the elastic force of the first spring, thereby forming a double fixation of the locking ring. This design not only cleverly limits the movement of the locking ring, but also ensures that the card block is stably maintained in the card slot and cannot fall out, thereby strengthening the connection strength between adjacent pole bodies. 4. The present invention sets a tilt detection component at the top of the utility pole, which can keenly capture the tilt change of the utility pole. When the utility pole is in a normal vertical state, the ball in the tilt detection component stays in the arc groove, and the first conductive ring and the second conductive ring remain separated, and the automatic alarm is in a closed state. However, once the utility pole tilts due to factors such as foundation settlement and vehicle collision, the ball will roll in the tilt direction under the guidance of gravity, push the second conductive ring to contact the first conductive ring, trigger the automatic alarm, and immediately send an alarm signal containing the location information of the utility pole to relevant personnel, so as to prompt the staff to respond quickly, deal with the tilt condition in time, effectively prevent the occurrence of utility pole dumping accidents, and eliminate safety hazards in time; 5. By setting up the feedback component, when the pole is tilted, the roller is squeezed and moved, driving the sliding plug through the connecting rod, pressing the oil into the installation cylinder, pushing the feedback block down. By observing the position of the feedback block, the staff can easily determine the tilt direction of the pole and the vertical state during the straightening process.

Except for the pole body 11 at the top of the main pole unit, the top of each of the remaining pole bodies 11 is fixed with a connecting tube 21. Except for the pole body 11 at the bottom of the main pole unit, the bottom of each of the remaining pole bodies 11 is fixed with a connecting seat 22. A bottom plate 12 is fixedly sleeved on the pole body 11 at the bottom of the main pole unit, and a positioning boss 13 (such as Fig.12 As shown in the figure, the positioning boss 13 is annular in structure and is sleeved on the rod body 11 at the bottom. The electric pole proposed by the present invention replaces the structure of the traditional long-rod electric pole. Each section of the rod body 11 can be independently disassembled and assembled. When erecting the electric pole, the staff can install each section of the rod body 11 one by one. Compared with the traditional long-rod electric pole, the rod body 11 is short in length and light in weight. The staff can easily lift, lower and adjust the position of it. This design is convenient for the staff to erect and assemble the electric pole. In addition, the detachable and separable rod body 11 can also provide convenience for the storage and transportation of the electric pole. In any two adjacent rod bodies, the connecting tube on one of the rod bodies is connected to the connecting seat on the other rod body through a connecting unit, and the connecting unit is composed of a clamping assembly and a locking assembly. The clamping assembly includes a fixing ring 23, a plurality of mounting ports 24 and a plurality of card slots 25. The top of the connecting tube 21 is open and the bottom is closed. The connecting seat 22 is inserted into the connecting tube 21. The outer peripheral surface of the connecting seat 22 and the inner surface of the connecting tube 21 fit each other. The fixing ring 23 is sleeved on the bottom end of the connecting tube 21, and the fixing ring 23 and the connecting tube 21 are connected by a plurality of bolts. The connecting tube 21 is provided with a plurality of mounting ports 24, and the connecting seat 22 is provided with a plurality of card slots 25. The card slot 25, each mounting port 24 is provided with a slidable card block 26, each card block 26 is provided with an inclined surface, the bottom surface of the connecting seat 22 is provided with a positioning groove 27, and the inner bottom surface of the connecting tube 21 is fixed with a positioning block 28, and the cross-sections of the positioning block 28 and the positioning groove 27 are both rectangular structures. When the connecting seat 22 is fully assembled into the inside of the connecting tube 21, the positioning block 28 is just inserted into the positioning groove 27. Under the positioning action of the positioning block 28 and the positioning groove 27, the plurality of card slots 25 on the connecting seat 22 are just arranged opposite to the plurality of card blocks 26, and the top surface of the fixing ring 23 is fixed with a plurality of protrusions, and the bottom surface of each card block 26 is provided with a slide groove, and the plurality of protrusions are respectively slidably arranged in the plurality of slide grooves (such as Figure 3 As shown in the figure, the locking assembly includes a locking ring 31, two mounting grooves 34 and two locking blocks 35. The locking ring 31 is sleeved on the connecting tube 21. The inner ring of the locking ring 31 is provided with two grooves 32. The outer peripheral surface of the locking ring 31 is provided with two through holes 33. The two through holes 33 are respectively connected with the two grooves 32. The two mounting grooves 34 are both provided on the outer peripheral surface of the connecting tube 21. The two locking blocks 35 are respectively slidably arranged in the two mounting grooves 34. Each locking block 35 is connected to the corresponding mounting groove 34 by a first spring 36. Each locking block 35 is provided with an inclined surface. When the locking ring 31 falls on the fixing ring 23, the locking ring 31 cannot continue to move. At this time, a plurality of clamping blocks 26 are respectively completely clamped in a plurality of clamping grooves 25. In addition, during this process, the locking ring 31 will squeeze the inclined surfaces of the two locking blocks 35. When the inclined surfaces of the locking blocks 35 are squeezed, they will also move and retract into the mounting grooves 34. When the locking ring 31 falls on the fixing ring 23, the grooves 32 on the locking ring 31 just move to a position facing the locking blocks 35. At this time, the locking blocks 35 will pop out from the mounting grooves 34 under the elastic force of the first spring 36 and be stuck in the grooves 32. In this case, the locking blocks 35 and the grooves 32 jointly clamp the locking ring 31, so that the locking ring 31 is fixed on the fixing ring 23. When the position of the locking ring 31 is fixed, the locking ring 31 can provide a limit for a plurality of blocks 26, so that the blocks 26 cannot be separated from the grooves 25. The sliding unit is composed of a lifting sleeve 41, a pressing assembly and a guide assembly. Both ends of the lifting sleeve 41 are open structures (such as Figure 7 As shown in the figure, the lifting sleeve 41 is slidably sleeved on the main rod unit, the size of the positioning boss 13 is adapted to the size of the inner ring of the lifting sleeve 41, two first cables 42 are connected to the lifting sleeve 41, the pressing assembly and the guide assembly are arranged on the lifting sleeve 41, the pressing assembly includes two through-holes 43, two movable plates 44 and two second cables 46, the two through-holes 43 are both opened on the lifting sleeve 41, and the two through-holes 43 are arranged opposite to each other, the two movable plates 44 are respectively slidably arranged in the two through-holes 43, and the two movable plates 44 The two second cables 46 are connected to the lifting sleeve 41 through the tension spring 45, and the two second cables 46 are respectively connected to the ends of the two movable plates 44 that are away from each other. When the lifting sleeve 41 passes through the connecting unit between two adjacent rod bodies 11, the lifting sleeve 41 will complete the locking between the connecting tube 21 and the connecting seat 22 through the pressing assembly and the locking assembly. When the lifting sleeve 41 moves to the lowest rod body 11, the lifting sleeve 41 finally falls on the bottom plate 12. At this time, the connecting tube 21 and the connecting seat 22 in each connecting unit will be locked. The guide assembly is composed of a plurality of guide structures, which are distributed in a circumferential array on the lifting sleeve 41. Each guide structure includes an opening 51, a sealing cylinder 52, a sliding plug 53, a connecting rod 55 and a roller 56. The opening 51 is opened on the lifting sleeve 41, and the sealing cylinder 52 is fixed in the opening 51. A hole is opened at one end of the sealing cylinder 52. The sliding plug 53 is sealingly and slidingly connected in the sealing cylinder 52. Oil is accumulated between the sliding plug 53 and the sealing cylinder 52. The sliding plug 53 is connected to the inner surface of the sealing cylinder 52 through a second spring 54. One end of the connecting rod 55 is fixedly connected to the sliding plug 53, and the other end passes through the hole. One end of the connecting rod 55 located outside the sealing cylinder 52 extends to the inside of the lifting sleeve 41 and is fixedly connected to the housing of the roller 56. Under the action of elastic force, each roller 56 has a tendency to press the rod body 11. Under the joint action of several rollers 56, the lifting sleeve 41 can always maintain a coaxial state with the rod body 11. Several rollers 56 jointly provide a limit for the movement of the lifting sleeve 41 to ensure the movement stability of the lifting sleeve 41 and avoid the lifting sleeve 41 from shaking during the descent process. In addition, when the lifting sleeve 41 passes through the connecting unit, several rollers 56 will contact the connecting seat 22, the connecting tube 21, the fixing ring 23 and other structures. When the roller 56 is blocked by the above components, the roller 56 can move and drive the sliding plug 53 to move through the connecting rod 55. The movable characteristics of the roller 56 can avoid the situation where the roller 56 and the components in the connecting unit have movement interference; The top of the rod body 11 at the top is provided with a tilt detection component, and the outer peripheral surface of the lifting sleeve 41 is provided with a plurality of feedback components, which are distributed in a circumferential array on the outer peripheral surface of the lifting sleeve 41, and the plurality of feedback components are respectively provided opposite to the plurality of sealing cylinders 52; The tilt detection component includes a mounting box 61, an arc groove 62, a ball 63, a first conductive ring 64, a second conductive ring 65 and an automatic alarm 66. The mounting box 61 is fixed to the top of the rod body 11, the arc groove 62 is opened on the inner bottom surface of the mounting box 61, the ball 63 is arranged in the arc groove 62, the first conductive ring 64 is fixed inside the mounting box 61, the second conductive ring 65 is slidably arranged inside the mounting box 61, the second conductive ring 65 is located inside the first conductive ring 64, the ball 63 is located inside the second conductive ring 65, the automatic alarm 66 is arranged on the inner top surface of the mounting box 61, the first conductive ring 64, the second conductive ring 65 and The automatic alarm 66 is electrically connected. When the electric pole tilts due to ground settlement or vehicle collision, the ball 63 will roll in the tilt direction of the electric pole under the action of gravity and push the second conductive ring 65 to move until the second conductive ring 65 contacts the first conductive ring 64. When the second conductive ring 65 contacts the first conductive ring 64, the automatic alarm 66 will be powered on and automatically send an alarm signal to relevant personnel, and send the location information of the electric pole at the same time, so that the staff can deal with the tilt of the electric pole in time, avoid the phenomenon of the electric pole tipping due to long-term tilting, and eliminate safety hazards in time. The feedback assembly includes a mounting tube 57, a feedback block 59 and a connecting tube 511. The mounting tube 57 is fixed to the outer circumference of the lifting sleeve 41. The outer circumference of the mounting tube 57 is provided with an observation window 58. The feedback block 59 is sealingly slidably arranged inside the mounting tube 57. The feedback block 59 is connected to the inner bottom surface of the mounting tube 57 through a third spring 510. One end of the connecting tube 511 is connected to the top end of the mounting tube 57, and the other end of the connecting tube 511 is connected to the end of the sealing tube 52 away from the roller 56. The outer circumference of the mounting tube 57 A reference line is provided. When the utility pole is tilted, the lowest rod body 11 will squeeze the roller 56 in the tilting direction. The roller 56 will move when squeezed by the rod body 11, and drive the sliding plug 53 to move through the corresponding connecting rod 55. When the sliding plug 53 moves, the oil can be pressed into the corresponding installation cylinder 57 through the connecting pipe 511. When the oil enters the installation cylinder 57, the oil will push the feedback block 59 to move downward. Therefore, the staff can judge the tilting direction of the utility pole by the position of each feedback block 59.

[0020] The specific working principle of the present invention is as follows: The utility pole proposed in the present invention is composed of a plurality of pole bodies 11, and two adjacent pole bodies 11 are connected by a connecting unit. When the plurality of pole bodies 11 are assembled together, they form a long pole-shaped structure. The utility pole proposed in the present invention replaces the structure of the traditional long pole-shaped utility pole. Each section of the pole body 11 can be independently disassembled and assembled. When erecting the utility pole, the staff can install each section of the pole body 11 one by one. Compared with the traditional long pole-shaped utility pole, the pole body 11 is short in length and light in weight. The staff can easily lift, lower and adjust the position of the pole. This design is convenient for the staff to erect and assemble the utility pole. In addition, the detachable and separable pole body 11 can also provide convenience for the storage and transportation of the utility pole. When erecting the utility pole proposed by the present invention, the staff first inserts the pole body 11 provided with the bottom plate 12 into the pre-opened pit on the ground and fixes it, and then installs the cross arm for erecting the electric wire on the pole body 11 provided with the installation box 61. Then, the staff splices the pole bodies 11 one by one. When the pole bodies 11 with the cross arm are assembled, the plurality of pole bodies 11 will form a long pole-shaped structure (such as Figure 1 As shown in the figure, when docking two adjacent rod bodies 11, the staff uses the connecting unit to complete the connection between the two. Specifically, in the initial state, the plurality of card blocks 26 are located away from the center of the connecting tube 21. At this time, each card block 26 does not extend into the connecting tube 21, and the locking ring 31 is arranged on the inclined surface of the plurality of card blocks 26. At this time, the locking ring 31 is located at the top position of the connecting tube 21. When connecting the rod bodies 11, the staff inserts the connecting seat 22 on one of the rod bodies 11 into the connecting tube 21 on the other rod body 11. During the plugging process, it is necessary to ensure that the positioning groove 27 is aligned with the positioning block 28. When the connecting seat 22 is fully installed When it is matched to the inside of the connecting tube 21, the positioning block 28 is just inserted into the positioning groove 27. Under the positioning effect of the positioning block 28 and the positioning groove 27, the plurality of card slots 25 on the connecting seat 22 are just arranged opposite to the plurality of card blocks 26. The staff can complete the preliminary assembly between the two adjacent rod bodies 11 in the above manner. Further, the staff gradually splices the rod bodies 11 upwards. When splicing the topmost rod body 11, the staff needs to insert the lifting sleeve 41 from the bottom end of the rod body 11 so that the lifting sleeve 41 is sleeved on the topmost rod body 11. After arranging the lifting sleeve 41, the staff continues to splice the top rod body 11. When each rod body 11 is arranged, the staff can use the two first cables 42 to pull the lifting sleeve 41 downwards, so that the lifting sleeve 41 gradually moves downwards along the plurality of rod bodies 11. When the lifting sleeve 41 passes through the connecting unit between two adjacent rod bodies 11, the lifting sleeve 41 will complete the locking between the connecting tube 21 and the connecting seat 22 through the pressing assembly and the locking assembly. When the lifting sleeve 41 moves to the lowest rod body 11, the lifting sleeve 41 finally falls on the bottom plate 12. At this time, the connecting tube 21 and the connecting seat 22 in each connecting unit will be locked, and finally the locking and fixing of the plurality of rod bodies 11 will be completed, so as to ensure the overall stability of the electric pole proposed by the present invention. Specifically, in the process of the lifting sleeve 41 passing through the connecting unit, the two movable plates 44 on the lifting sleeve 41 will contact with the locking ring 31 and press down the locking ring 31 so that the locking ring 31 When the locking ring 31 moves downward, the inclined surfaces of the plurality of blocks 26 are squeezed when the locking ring 31 moves downward. When the inclined surface position of the block 26 is squeezed, the block 26 moves toward the direction close to the connecting seat 22 until the block 26 is stuck in the slot 25. In summary, in the process of the lifting sleeve 41 driving the locking ring 31 downward through the two movable plates 44, the plurality of blocks 26 can move synchronously and approach each other until the plurality of blocks 26 are respectively stuck in the plurality of slots 25. At this time, the plurality of blocks 26 and the plurality of slots 25 jointly realize the locking operation of the connecting seat 22 and the connecting tube 21 to achieve a stable connection between the two. When the locking ring 31 moves to the extreme position, the staff pulls the two movable plates 44 through the two second pull cables 46 until the two movable plates 44 are respectively retracted into the two through-holes 43. At this time, the two movable plates 44 are staggered with the locking ring 31 to facilitate the continued downward movement of the lifting sleeve 41. When the locking ring 31 falls on the fixing ring 23, the locking ring 31 cannot move further. At this time, the plurality of clamping blocks 26 are completely inserted into the plurality of clamping grooves 25. In addition, during this process, the locking ring 31 will squeeze the inclined surfaces of the two locking blocks 35. When the inclined surface position of the locking block 35 is squeezed, it will also move and retract into the mounting groove 34. When the locking ring 31 falls on the fixing ring 23, the groove 32 on the locking ring 31 just moves to a position facing the locking block 35. At this time, the locking block 35 will pop out of the mounting groove 34 under the elastic force of the first spring 36 and be inserted into the groove 32. In this case, the locking block 35 and the groove 32 jointly clamp the locking ring 31, so that the locking ring 31 is fixed on the fixing ring 23. When the position of the locking ring 31 is fixed, the locking ring 31 can The block 26 provides a limit so that the block 26 cannot be separated from the slot 25, thereby ensuring the fixing effect of the plurality of blocks 26 and the plurality of slots 25 on the two adjacent rod bodies 11. It is worth noting that when the locking ring 31 falls on the fixing ring 23, if the two grooves 32 fail to face the two locking blocks 35 exactly, the staff can climb the pole with the help of the foot buckle after the assembly process is completed, and then manually rotate the locking ring 31. When the locking ring 31 rotates, the two grooves 32 thereon rotate accordingly. When the two grooves 32 rotate to a position facing the two locking blocks 35, the locking ring 31 will not be able to continue to rotate. The staff can judge whether the two locking blocks 35 are clamped in place by whether the locking ring 31 can rotate. The purpose of this operation is to ensure the stability of the overall structure of the pole proposed by the present invention. For the lifting sleeve 41, a guide assembly is arranged thereon, and the guide assembly is composed of a plurality of guide structures. Specifically, under the elastic force of a plurality of second springs 54, each roller 56 has a tendency to press the rod body 11. Under the joint action of a plurality of rollers 56, the lifting sleeve 41 can always maintain a coaxial state with the rod body 11. The plurality of rollers 56 jointly provide a limit for the movement of the lifting sleeve 41 to ensure the movement stability of the lifting sleeve 41 and avoid the lifting sleeve 41 from shaking during the descent process. In addition, when the lifting sleeve 41 passes through the connecting unit, the plurality of rollers 56 will contact the connecting seat 22, the connecting tube 21 and the fixed When the roller 56 is blocked by the above components, the roller 56 can move and drive the sliding plug 53 to move through the connecting rod 55. The movable characteristics of the roller 56 can avoid the movement interference between the roller 56 and the components in the connecting unit, thereby ensuring the smooth descent of the lifting sleeve 41. When the lifting sleeve 41 falls on the bottom plate 12, the positioning boss 13 is just stuck in the inside of the lifting sleeve 41. At this time, the outer peripheral surface of the positioning boss 13 and the inner surface of the lifting sleeve 41 fit each other. This design can ensure the stability of the lifting sleeve 41 on the bottom plate 12 and avoid the position deviation of the lifting sleeve 41. The utility pole proposed by the present invention is not only easy to erect, but also has the function of tipping detection. Specifically, a tilt detection component is arranged at the top of the uppermost pole body 11. When the pole body 11 is in a vertical state, the ball 63 is located in the arc groove 62, and the first conductive ring 64 and the second conductive ring 65 are not in contact with each other, and the automatic alarm 66 is also in a power-off state. When the utility pole is tilted due to foundation settlement or vehicle collision, the ball 63 will roll in the tilt direction of the utility pole under the action of gravity, and push the second conductive ring 65 to move until the second conductive ring 65 contacts the first conductive ring 64. When the second conductive ring 65 contacts the first conductive ring 64, the automatic alarm 66 will be energized and automatically send an alarm signal to relevant personnel, and at the same time send the position information of the utility pole, so that the staff can deal with the tilt of the utility pole in time to avoid the phenomenon of the utility pole tipping due to long-term tilting. , timely eliminate safety hazards. In addition, when the utility pole tilts, the lowest rod body 11 will squeeze the roller 56 in the tilting direction. When the roller 56 is squeezed by the rod body 11, it will move and drive the sliding plug 53 to move through the corresponding connecting rod 55. When the sliding plug 53 moves, it can press the oil into the corresponding installation cylinder 57 through the connecting pipe 511. When the oil enters the installation cylinder 57, the oil will push the feedback block 59 to move downward. Therefore, the staff can judge the tilting direction of the utility pole by the position of each feedback block 59. At the same time, during the straightening process, the staff can also judge whether the utility pole is in a vertical state according to the position of each feedback block 59. Furthermore, a reference line is set on each installation cylinder 57. When the bottom end of the feedback block 59 is aligned with the reference line, it means that the utility pole is in a vertical state. The setting of the reference line also facilitates the staff to judge the position state of the feedback block 59 more intuitively.
