Description

Technical Field

[0001] This invention relates to the field of power tower technology, specifically to a power tower structure with a modular tower body and its assembly method. Background Technology

[0002] As the core structure of power grid projects, power transmission towers bear the important mission of supporting conductors and ensuring power transmission safety. Traditional power towers mostly adopt angle steel tower structures, and the main body is assembled by on-site welding or bolting. As power transmission projects expand to high voltage, long distance, and complex terrain, the traditional structure has gradually revealed the following limitations: 1. A large power transmission angle steel tower often requires many parts. The on-site assembly process is complicated, requiring a large number of skilled workers and high-altitude operations. The construction period is long, the labor cost is high, and it is difficult for machinery to enter the site in complex terrains such as mountains and swamps. The construction period can last for several weeks to several months, which seriously affects the progress of power grid construction.

[0003] 2. A large number of bolted connections require high-altitude operations during the gradual assembly of the tower, which exposes workers to risks such as falls and being struck by objects for extended periods, making safety management difficult.

[0004] To improve construction efficiency, the industry has proposed modular power tower solutions in recent years, such as flange-connected tower sections. These sections are pre-divided into several parts and spliced ​​together with flange bolts. While this solution reduces the amount of high-altitude work, the flanges need to be custom-forged, resulting in high manufacturing costs. Furthermore, the flatness requirements for the large flange connection surfaces are stringent, and on-site leveling is time-consuming.

[0005] Therefore, there is an urgent need to develop a new type of power tower structure that combines modularity, lightweight, high efficiency in assembly, high structural reliability, convenient construction, and low cost of manufacturing. While ensuring mechanical performance, it should significantly reduce construction complexity and total life cycle cost. To this end, we provide a modular power tower structure and its assembly method to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a modular power tower structure and its assembly method, which combines modularity, lightweight, high efficiency in assembly, high structural reliability, convenient construction, and low-cost manufacturing. This addresses the problems mentioned in the background art, such as the need for a large number of bolts in the splicing of existing power transmission angle steel towers, resulting in long construction cycles, high labor costs, and difficulties in safety management due to the need for high-altitude operations during the gradual erection of the tower body.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A modular power tower structure includes a tower frame with multiple connecting blocks on the tower frame. Each connecting block has a limiting groove, and a support column is movably inserted into the limiting groove. Both ends of the support column are connected to a conical head via connecting rods. The connecting block has a locking block that movably engages with the conical head. The connecting block also has an elastic clearance component, allowing the locking block to move horizontally within the connecting block via the elastic clearance component. The support column has a slot, the connecting block has a fixed seat, and two inclined support plates are hinged together above the fixed seat. One end of the inclined support plate has a locking pin, and the other end is hinged to an adjusting block. The fixed seat has a driving mechanism for moving the adjusting block on the fixed seat, and the locking pin is movably engaged inside the slot.

[0008] As described above, the structure of a modular power tower consists of three ring-shaped supports from top to bottom, with adjacent ring-shaped supports fixed together by bolts.

[0009] As described above, the structure of a power tower with a modular tower body is as follows: the number of connecting blocks is set to 8, the 8 connecting blocks are symmetrically distributed on the tower, and one end of the connecting block is fixed between adjacent annular supports.

[0010] As described above, the structure of a power tower with a modular tower body is as follows: the outer dimensions of the support column and the conical head are adapted to the inner dimensions of the limiting groove, the conical head is movably inserted into the limiting groove, and the support column is embedded and snapped into the limiting groove.

[0011] As described above, a modular power tower structure includes an elastic clearance component comprising a cylinder fixed inside a connecting block, a movable rod movably engaged within the cylinder, a spring being provided between one end of the movable rod and the inner wall of the cylinder, and the other end being fixed to the locking block, and an anti-detachment component being provided between the cylinder and the movable rod to prevent the movable rod from slipping out of the cylinder.

[0012] As described above, a modular power tower structure includes an anti-detachment component comprising a stop plate fixed to a movable rod and a stop ring fixed to the end of the cylinder. The outer diameter of the stop plate is larger than the inner diameter of the stop ring, and the stop plate is movably engaged inside the cylinder.

[0013] As described above, a modular power tower structure is constructed such that the inner dimensions of the slot are adapted to the outer dimensions of the pin, and the pin can be movably embedded and engaged inside the slot.

[0014] As described above, a modular power tower structure includes a drive mechanism comprising a mounting base fixed to a fixed seat, a limit rod on the mounting base, a bidirectional lead screw rotatably mounted on the mounting base, a handwheel at the end of the bidirectional lead screw, a threaded hole and a limit hole on the adjusting block, the bidirectional lead screw being movably inserted into the threaded hole and threadedly engaged with it, and the limit rod being movably inserted into the limit hole.

[0015] As described above, a power tower structure with a modular tower body includes a hinged rod on the adjusting block, and a through hole at one end of the inclined support plate, which is movably fitted onto the hinged rod.

[0016] A method for assembling a modular power tower structure includes the following steps; S1, When assembling the tower body, the two ends of the support column are respectively movably inserted into the limiting grooves opened on the connecting blocks set on the adjacent towers; S2, after the conical head is inserted into the limiting groove, the block will first elastically yield when it is squeezed by the conical head under the action of the elastic yielding component. Then, after the conical head continues to move down to the bottom of the block, the conical head is clamped, and the support column is used to realize the clamping and fixing between adjacent towers. S3, then the hand crank drives the double-acting screw to rotate. The adjusting block and the double-acting screw are threaded together to drive the two adjusting blocks to move synchronously in opposite directions, which in turn drives the inclined support plate hinged on the adjusting block to rotate. Then, the locking pin at the end of the inclined support plate is driven to engage with the slot opened on the support column, thereby realizing the locking and fixing between the inclined support plate and the support column. The inclined support plate is used to support the adjacent support columns.

[0017] Compared with the prior art, the beneficial effects of the modular power tower structure of the present invention are as follows: During use, when assembling the tower body, the two ends of the support column are first movably inserted into the limiting grooves opened on the connecting blocks set on the adjacent towers; after the conical head is inserted into the limiting groove, the locking block will elastically yield when squeezed by the conical head under the action of the elastic yielding component, and then the conical head will be locked after the conical head continues to move down to the bottom of the locking block, thereby using the support column to achieve the locking and fixing between adjacent towers; then, the hand crank drives the bidirectional screw to rotate, and the adjusting block and the bidirectional screw threadedly engage to drive the two adjusting blocks to move synchronously in opposite directions, thereby driving the inclined support plate hinged on the adjusting block to rotate, and then driving the locking pin at the end of the inclined support plate to embed into the locking groove opened on the support column, thereby achieving the locking and fixing between the inclined support plate and the support column, and using the inclined support plate to support the adjacent support columns; Therefore, the modular power tower structure of the present invention achieves plug-in and fixed connection by using a conical head and a locking block for locking and limiting, and a locking pin and a locking slot for locking and limiting, eliminating a large number of high-strength bolt connections, making the tower assembly construction operation less cumbersome, shortening the construction cycle, and enabling rapid tower assembly. At the same time, the support columns and diagonal bracing plates connect and support adjacent towers, ensuring the high structural reliability of the tower body after the tower is assembled.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Please see Figures 1-10 As an embodiment of the present invention, a power tower structure with a modular tower body includes a tower frame 1, a plurality of connecting blocks 2 are provided on the tower frame 1, a limiting groove 3 is provided on the connecting block 2, a support column 4 is movably inserted into the limiting groove 3, and a conical head 5 is connected to both ends of the support column 4 through a connecting rod, a locking block 6 is provided inside the connecting block 2 to movably engage with the conical head 5, and an elastic clearance component is provided inside the connecting block 2, and the locking block 6 can move horizontally inside the connecting block 2 through the elastic clearance component.

[0031] The support column 4 has a slot 11, the connecting block 2 has a fixed seat 12, and two inclined support plates 13 are hinged together above the fixed seat 12. One end of the inclined support plate 13 is provided with a locking pin 14, and the other end is hinged to an adjusting block 15. The fixed seat 12 is provided with a drive mechanism to drive the adjusting block 15 to move on the fixed seat 12. The locking pin 14 is movably engaged inside the slot 11.

[0032] In this embodiment, during tower assembly, the two ends of the support column 4 are first movably inserted into the limiting grooves 3 on the connecting blocks 2 on adjacent tower frames 1; the top end of the support column 4 is inserted into the limiting groove 3 on the connecting block 2 on the lower part of one tower frame 1, and the bottom end of the support column 4 is inserted into the limiting groove 3 on the connecting block 2 on the upper part of another tower frame 1, so that adjacent tower frames 1 are connected by the support column 4. After the conical head 5 is inserted into the limiting groove 3, the locking block 6 will first... When squeezed by the conical head 5, the cone head 5 elastically yields, and then, after the cone head 5 continues to move down to the bottom of the locking block 6, the cone head 5 is locked, and the locking and fixing between adjacent towers 1 is achieved by the support column 4; then, the driving mechanism drives the two adjusting blocks 15 to move synchronously in opposite directions, causing the inclined bracing plate 13 hinged on the adjusting block 15 to rotate, and then the locking pin 14 at the end of the inclined bracing plate 13 is driven to embed into the locking groove 11 opened on the support column 4, thereby achieving the locking and fixing between the inclined bracing plate 13 and the support column 4, and using the inclined bracing plate 13 to support the adjacent support columns 4.

[0033] As a further embodiment of the present invention, the tower 1 is composed of three annular supports from top to bottom, and adjacent annular supports are fixed together by bolts.

[0034] In this embodiment, the adjacent annular supports are fixed together with bolts, allowing the tower 1 to be pre-assembled and modularized for direct installation during assembly. Furthermore, by setting the tower 1 as a circular support, the circular support, due to its structural characteristics, exhibits a more uniform pressure distribution under pressure, making it less prone to localized deformation. Stress analysis of the circular structure shows that it can better disperse pressure and reduce localized stress concentration, thereby improving the overall stability of the tower. In addition, when subjected to a force in a single direction, the circular support, due to its geometric shape, can better maintain equilibrium and is less prone to deformation. As a further embodiment of the present invention, the number of connecting blocks 2 is set to 8, and the 8 connecting blocks 2 are symmetrically distributed on the tower 1, with one end of the connecting block 2 fixed between adjacent annular supports.

[0035] In this embodiment, the connecting blocks 2 are set in two layers, with four in each layer. The four connecting blocks 2 are symmetrically distributed on the tower 1. The connecting blocks 2 can be used for fixed connection between adjacent ring supports, to support the ring supports, and to increase the overall structural strength.

[0036] As a further embodiment of the present invention, the outer dimensions of the support column 4 and the conical head 5 are adapted to the inner dimensions of the limiting groove 3, the conical head 5 is movably inserted into the limiting groove 3, and the support column 4 is embedded and snapped into the limiting groove 3.

[0037] In this embodiment, the support column 4 is embedded and snapped into the limiting groove 3 to achieve positioning and snapping between the support column 4 and the connecting block 2, so that the support column 4 is snapped into the connecting block 2. Then, the support column 4 can be further snapped into the conical head 5 by the snapping block 6 to lock it in place.

[0038] As a further embodiment of the present invention, the elastic clearance component includes a cylinder 7 fixed inside the connecting block 2, a movable rod 8 movably engaged inside the cylinder 7, a spring 9 provided between one end of the movable rod 8 and the inner wall of the cylinder 7, and the other end fixed to the locking block 6, and an anti-detachment component provided between the cylinder 7 and the movable rod 8 to prevent the movable rod 8 from slipping out of the cylinder 7.

[0039] In this embodiment, after the support column 4 is embedded and engaged inside the limiting groove 3, the conical head 5 will compress the locking block 6. The compressive force is transmitted to the spring 9, which will compress the spring 9 and put the spring 9 in a compressed state. When the conical head 5 continues to compress the locking block 6, it will move to the bottom of the locking block 6. Then the conical head 5 will release the compression of the locking block 6, and the spring 9 will quickly and elastically reset, so that the locking block 6 is locked on the upper surface of the conical head 5 to lock and limit the conical head 5. This ensures that the conical head 5 will not come off after being engaged inside the limiting groove 3, thus ensuring the stability of the support column 4 after being connected to the connecting block 2.

[0040] The above describes the structure of a modular power tower: the anti-detachment component includes a stop plate 10 fixed on the movable rod 8 and a stop ring 24 fixed at the end of the cylinder 7. The outer diameter of the stop plate 10 is larger than the inner diameter of the stop ring 24, and the stop plate 10 is movably engaged inside the cylinder 7.

[0041] In this embodiment, after the stop plate 10 is movably engaged inside the cylinder 7, since the outer diameter of the stop plate 10 is larger than the inner diameter of the stop ring 24, when the spring 9 elastically resets and drives the movable rod 8 to move, the stop ring 24 blocks the stop plate 10, preventing the movable rod 8 from disengaging from inside the cylinder 7.

[0042] The above describes a modular power tower structure: the inner dimensions of the slot 11 are compatible with the outer dimensions of the pin 14, and the pin 14 can be movably embedded and engaged inside the slot 11.

[0043] In this embodiment, the driving mechanism drives the two adjusting blocks 15 to move synchronously in opposite directions, causing the inclined support plate 13 hinged on the adjusting block 15 to rotate. Then, the locking pin 14 at the end of the inclined support plate 13 is driven to be inserted into the locking groove 11 opened on the support column 4, thereby realizing the locking and fixing between the inclined support plate 13 and the support column 4. The inclined support plate 13 can support the adjacent support columns 4.

[0044] The above describes the structure of a modular power tower: the drive mechanism includes a mounting base 16 fixed on a fixed base 12, a limit rod 18 on the mounting base 16, a bidirectional lead screw 17 rotatably mounted on the mounting base 16, a handwheel 19 at the end of the bidirectional lead screw 17, and a threaded hole 20 and a limit hole 21 on the adjusting block 15. The bidirectional lead screw 17 is movably inserted into the threaded hole 20 and threadedly engaged with the threaded hole 20, and the limit rod 18 is movably inserted into the limit hole 21.

[0045] In this embodiment, the handwheel 19 drives the bidirectional lead screw 17 to rotate. The bidirectional lead screw 17 is movably inserted into the threaded hole 20 on the adjusting block 15 and the threaded engagement with the threaded hole 20 drives the two adjusting blocks 15 to move synchronously in opposite directions, causing the inclined support plate 13 hinged on the adjusting block 15 to rotate. Then, the locking pin 14 at the end of the inclined support plate 13 is driven to engage with the locking groove 11 on the support column 4, realizing the locking and fixing between the inclined support plate 13 and the support column 4. The limiting rod 18 is movably inserted into the limiting hole 21 to limit the horizontal movement of the adjusting block 15 and prevent its position from shifting during movement.

[0046] The above describes the structure of a power tower with a modular tower body: a hinge rod 22 is provided on the adjusting block 15, and a through hole 23 is provided at one end of the inclined support plate 13, which is movably fitted onto the hinge rod 22.

[0047] In this embodiment, the adjusting block 15 is provided with a hinge rod 22, and one end of the diagonal brace 13 is provided with a through hole 23. The adjusting block 15 can be rotatably mounted on the hinge rod 22 through the through hole 23, and the adjusting block 15 can rotate around the hinge rod 22. The diagonal bracing reinforcement using the diagonal brace 13 is the basis for ensuring the stability of the tower 1. The diagonal bracing reinforcement can change the force system of the tower 1 structure, effectively disperse external forces, maintain the stability of the tower 1, and prevent the tower 1 structure from deforming and becoming unstable. In the face of natural disasters such as strong winds or earthquakes, the diagonal bracing reinforcement using the diagonal brace 13 can significantly improve the lateral stiffness of the structure, absorb seismic energy, reduce horizontal displacement and vibration response, thereby reducing the risk of damage to the tower 1.

[0048] In use, during tower assembly, the tower body is assembled from multiple tower frames 1 sequentially from bottom to top. First, the two ends of the support column 4 are movably inserted into the limiting grooves 3 opened on the connecting blocks 2 on the adjacent tower frames 1. After the support column 4 is embedded and locked into the limiting grooves 3, the conical head 5 will squeeze the locking block 6. The squeezing force is transmitted to the spring 9, which will squeeze the spring 9 and put the spring 9 in a compressed state. When the conical head 5 continues to squeeze the locking block 6, it will move to the bottom of the locking block 6, and then the conical head 5 will release the squeezing of the locking block 6. The spring 9 will quickly and elastically return to its original position, causing the locking block 6 to lock onto the upper surface of the conical head 5, thus locking the conical head 5. The conical head 5 is positioned so that it will not disengage after being engaged in the limiting groove 3. The support column 4 is used to achieve the engagement and fixation between adjacent towers 1. The hand crank 19 drives the bidirectional screw 17 to rotate. The bidirectional screw 17 is movably inserted into the threaded hole 20 on the adjusting block 15 and the threaded engagement with the threaded hole 20 drives the two adjusting blocks 15 to move synchronously in opposite directions, causing the inclined support plate 13 hinged on the adjusting block 15 to rotate. Then, the locking pin 14 at the end of the inclined support plate 13 is driven to embed into the locking groove 11 on the support column 4, thereby achieving the engagement and fixation between the inclined support plate 13 and the support column 4. The inclined support plate 13 is used to support the adjacent support columns 4.

[0049] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
