Description

Technical Field

[0001] This invention relates to the field of power transmission technology, and more specifically, to a single-circuit landscape tower. Background Technology

[0002] With the rapid development of China's power grid construction, transmission line routes are significantly influenced by planning, especially in economically developed regions where new lines intersect with existing lines to varying degrees. When lines of different voltage levels intersect, the common practice is for the higher-voltage line to cross the lower-voltage line, or for the lower-voltage line to tunnel under the higher-voltage line. Using conventional towers for tunneling or crossing at intersections is no longer sufficient; using cables or other methods not only increases project investment but also creates difficulties in construction and operation. Therefore, designing new tunneling / crossing towers is of great significance, and this invention mainly focuses on a novel tunneling / crossing tower.

[0003] Among related technologies, power poles occupy a large area, have wide transmission corridors, high investment costs, and have a limited range of shapes. Summary of the Invention

[0004] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0005] (1) With the development of society and economy, more and more lines pass through or are adjacent to scenic spots, nature reserves, rivers and lakes. Owners and residents have put forward high requirements for the appearance of the iron tower. Conventional iron tower shapes are difficult to meet the requirements of iron tower appearance in special locations.

[0006] (2) The guy wire range of a guyed tower is much larger than that of a self-supporting tower. In economically developed areas, the guy wire may collide with existing buildings, structures, pipelines, etc. In mountainous areas, the guy wire is prone to being too long, with large sag, making it difficult to tighten and operation and maintenance. The guy wire range leads to an increase in the land area required for the tower, which in turn leads to an increase in the overall investment of the line.

[0007] (3) Self-supporting iron towers solve the problem of a large guying range in guyed towers. However, because self-supporting iron towers use a square cross-section composed of four legs, and there are a large number of cross-sloping steel bars on the front and side, sloping steel bars on the tower legs, and V-shaped steel bars on the tower legs, the tower weight of a single iron tower increases significantly. At the same time, the construction period is longer, which leads to an increase in the overall investment of the line.

[0008] (4) At the locations where transmission lines cross, especially between lines of different voltage levels, the route often needs to be adjusted due to issues such as the safety distance between the towers at the crossing point, which in turn increases the investment in the project. This is especially common in economically developed areas with a high density of transmission corridors.

[0009] The present invention aims to at least partially solve one of the technical problems in the related art.

[0010] Therefore, embodiments of the present invention propose a single-loop landscape tower that is rationally designed, occupies a small area, has low investment costs, and has a novel and unique appearance.

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following is a reference appendix. Figure 1 A single-loop landscape tower 100 according to an embodiment of the present invention is described.

[0032] like Figure 1 As shown, the single-circuit landscape tower 100 according to an embodiment of the present invention includes a tower body 1, a first ground wire suspension point 21, a second ground wire suspension point 22, a first conductor suspension point 31, a second conductor suspension point 32, a third conductor suspension point 33, a first jumper string suspension point 41, and a second jumper string suspension point 42.

[0033] The tower body 1 is arch-shaped and includes a first main pole 11, a second main pole 12, a first crossarm 13, a second crossarm 14, a third crossarm 15, a fourth crossarm 16, and a fifth crossarm 17. The first main pole 11 and the second main pole 12 are arranged parallel to each other at intervals. The first main pole 11 includes a first section (not shown in the figure) and a second section (not shown in the figure) connected sequentially in the vertical direction. The second main pole 12 includes a third section (not shown in the figure) and a fourth section (not shown in the figure) connected sequentially in the vertical direction. The fifth crossarm 17 is located between the first section and the third section, and its two ends are connected to the first section and the third section, respectively. The first crossarm 13 and the third crossarm 15 are both located on the side of the first section away from the third section and are arranged at intervals in the vertical direction. The second crossarm 14 and the fourth crossarm 16 are located on the side of the third section away from the first section and are arranged at intervals in the vertical direction.

[0034] Specifically, such as Figure 1As shown, the first main rod 11 and the second main rod 12 extend vertically and are spaced apart horizontally. The first segment is the upper segment of the first main rod 11, and the second segment is the lower segment of the first main rod 11. The first and second segments can be integrally formed or connected by a flange. The third segment is the upper segment of the second main rod 12, and the fourth segment is the lower segment of the second main rod 12. The third and fourth segments can be integrally formed or connected by a flange. The fifth crossbeam 17 is located between the first and third segments, and the left end of the fifth crossbeam 17 is connected to the first main rod 11 by a flange or a plate, and the right end of the fifth crossbeam 17 is connected to the second main rod 12 by a flange or a plate. The first crossarm 13 is located on the upper left side of the first section, the third crossarm 15 is located on the left side of the first section and below the first crossarm 13, the second crossarm 14 is located on the upper right side of the third section, and the fourth crossarm 16 is located on the right side of the third section and below the second crossarm 14. The first crossarm 13 and the third crossarm 15 are symmetrical about left and right with the second crossarm 14 and the fourth crossarm 16. Thus, the first crossarm 13, the second crossarm 14, the third crossarm 15, the fourth crossarm 16, the fifth crossarm 17, the first main rod 11 and the second main rod 12 form the shape of an archway.

[0035] The first grounding point 21 and the second grounding point 22 are respectively located at the ends of the first crossarm 13 and the second crossarm 14. Thus, the first grounding point 21 is installed at the left end of the first crossarm 13, and the second grounding point 22 is installed at the right end of the second crossarm 14.

[0036] The first conductor suspension point 31, the second conductor suspension point 32, and the third conductor suspension point 33 are respectively set on the third crossarm 15, the fourth crossarm 16, and the fifth crossarm 17. Thus, the first conductor suspension point 31 is set on the third crossarm 15, the second conductor suspension point 32 is set on the fourth crossarm 16, and the third conductor suspension point 33 is set on the fifth crossarm 17.

[0037] The first jumper string is installed on the third crossarm 15 and below the first conductor suspension point 31, and the second jumper string is installed on the fourth crossarm 16 and below the second conductor suspension point 32. This effectively utilizes the available space of the tower body 1.

[0038] The single-circuit landscape tower 100 of this invention includes a tower body 1, a first ground wire suspension point 21, a second ground wire suspension point 22, a first conductor suspension point 31, a second conductor suspension point 32, a third conductor suspension point 33, a first jumper string suspension point 41, and a second jumper string suspension point 42. The single-circuit landscape tower 100 has the shape of a tower and can be used in sections with special needs for natural or cultural landscapes. It meets design requirements while integrating with the surrounding landscape. Furthermore, the first main pole 11 and the second main pole 12 of the tower body 1 avoid the disadvantage of increased land acquisition area associated with guyed towers. Additionally, due to the first main pole 11... The tubular structure of pole 11, second main pole 12, first crossarm 13, second crossarm 14, third crossarm 15, fourth crossarm 16, and fifth crossarm 17, compared with towers in related technologies (such as goblet towers, cat-head towers, and T-shaped towers), can save a lot of time in processing, manufacturing, construction, and installation. At the same time, the footprint of the tower is greatly reduced, thus significantly saving project investment. Finally, the setting of the tower body 1 can significantly reduce the tower height and corridor width, enabling drilling to be completed when the drilling distance is insufficient due to the height requirement at many line drilling points. This avoids major route adjustments and reduces corridor width, thereby achieving the goal of saving engineering work.

[0039] In some embodiments, the third crossarm 15 includes a first crossbar 151, a second crossbar 152, a third crossbar 153, and a first insulating hanger 154. The first crossbar 151, the second crossbar 152, and the third crossbar 153 are sequentially arranged along the vertical direction on the side of the first main pole 11 away from the second main pole 12. The first insulating hanger 154 is located below the second crossbar 152 and connected to the free end of the third crossbar 153. A first conductor suspension point 31 is located on the second crossbar 152, and a first jumper string suspension point 41 is located at the lower end of the first insulating hanger 154. Specifically, as shown... Figure 1 As shown, the first crossbar 151, the second crossbar 152, and the third crossbar 153 all extend in the left-right direction and are arranged alternately in the up-down direction. In other words, the first crossbar 151 is located above the second crossbar 152, and the second crossbar 152 is located above the third crossbar 153. The first insulating hanger 154 extends in the up-down direction, and the third crossbar 153 is made of insulating composite material. The first crossbar 151 is a first decorative rod and is made of unequal diameter curved steel pipe. The first decorative rod and the rod are both bent upwards to roughly form a bull's horn shape, thereby further decorating the tower body 1 and making the tower body 1 more aesthetically pleasing. The first conductor hanging point 31 is located at the left end of the second crossbar 152, and the first jumper string hanging point 41 is located at the lower end of the first insulating hanger 154. Thus, through the reasonable layout of the third crossbar 15, not only are the requirements of the outer contour of the tower body 1 met, but the installation foundation for the first conductor hanging point 31 and the first jumper string hanging point 41 is also provided.

[0040] In some embodiments, the fourth crossarm 16 includes a fourth crossbar 161, a fifth crossbar 162, a sixth crossbar 163, and a second insulating hanger 164. The fourth crossbar 161, the fifth crossbar 162, and the sixth crossbar 163 are sequentially arranged along the vertical direction on the side of the second main rod 12 away from the first main rod 11. The second insulating hanger 164 is located below the fifth crossbar 162 and connected to the free end of the sixth crossbar 163. The second conductor suspension point 32 is located on the fifth crossbar 162, and the second jumper string suspension point 42 is located at the lower end of the second insulating hanger 164. Specifically, as shown... Figure 1 As shown, the fourth horizontal bar 161, the fifth horizontal bar 162, and the sixth horizontal bar 163 all extend in the left-right direction and are arranged alternately in the up-down direction. In other words, the fourth horizontal bar 161 is located above the fifth horizontal bar 162, and the fifth horizontal bar 162 is located above the sixth horizontal bar 163. The second insulating hanger 164 extends in the up-down direction. The fourth horizontal bar 161 is a second decorative bar and is made of unequal diameter curved steel pipe. Both the second decorative bar and the main bar are bent upwards to roughly form a bull's horn shape. Thus, it further decorates the tower body 1, making the tower body 1 more aesthetically pleasing. The sixth horizontal bar 163 is made of insulating composite material. The second conductor hanging point 32 is located at the left end of the fifth horizontal bar 162, and the second jumper string hanging point 42 is located at the lower end of the second insulating hanger 164. Thus, through the reasonable layout of the fourth horizontal bar 161, not only are the requirements of the outer contour of the tower body 1 met, but the installation foundation for the second conductor hanging point 32 and the second jumper string hanging point 42 is also provided.

[0041] In some embodiments, the third crossbar 153, the sixth crossbar 163, the first insulating rod 154, and the second insulating rod 164 are all made of insulating composite materials (e.g., fiberglass (FRP)). Compared with metal materials, the insulating composite materials have excellent electrical insulation properties, which can reduce the dimensions of the third crossbar 153 and the sixth crossbar 163 in the left-right direction and the dimensions of the first insulating rod 154 and the second insulating rod 164 in the up-down direction, thereby reducing the size of the tower body 1. At the same time, from a mechanical point of view, reducing the cantilever length of the third crossbar 153 and the sixth crossbar 163 can reduce the steel pipe specifications of the main pipe, thereby reducing the processing and manufacturing cost of the tower body 1.

[0042] In some embodiments, the first crossarm 13 extends in a direction away from the first main rod 11 and is inclined in a direction away from the third crossarm 15, and the cross-sectional area of ​​the first crossarm 13 gradually decreases in a direction away from the first main rod 11. The second crossarm 14 extends in a direction away from the second main rod 12 and is inclined in a direction away from the fourth crossarm 161, and the cross-sectional area of ​​the second crossarm 14 gradually decreases in a direction away from the second main rod 12. Specifically, as Figure 1As shown, the first crossarm 13 and the second crossarm 14 are both curved steel pipes of unequal diameter. Both the first crossarm 13 and the second crossarm 14 are bent upwards to roughly form a bull's horn shape, thereby improving the aesthetics of the tower body 1.

[0043] In some embodiments, the single-loop landscape tower 100 further includes a first reinforcing plate 18 and a second reinforcing plate 19. The first reinforcing plate 18 is disposed on the first main pole 11, located below and connected to the first crossarm 13. The second reinforcing plate 19 is disposed on the second main pole 12, located below and connected to the second crossarm 14. Specifically, as... Figure 1 As shown, both the first reinforcing plate 18 and the second reinforcing plate 19 are stiffened square steel pipes. The first reinforcing plate 18 is located on the left side of the first section and is welded to the lower side of the first crossarm 13. Thus, the first reinforcing plate 18 improves the load-bearing performance of the first crossarm 13. The second reinforcing plate 19 is located on the right side of the third section and is welded to the lower side of the second crossarm 14. Thus, the second reinforcing plate 19 improves the load-bearing performance of the second crossarm 14.

[0044] In some embodiments, the single-loop landscape tower 100 further includes a first flange (not shown in the figure) and a second flange (not shown in the figure). The first flange is located at the lower end of the first main pole 11, and the second flange is located at the lower end of the second main pole 12. Both the first flange and the second flange are adapted to be connected to anchor bolts. Specifically, the first flange is fixed to the lower end of the first main pole 11 by welding or fasteners, and the second flange is fixed to the lower end of the second main pole 12 by welding or fasteners. Thus, the tower body 1 can be fixed in a preset position by the cooperation of the first flange and the second flange with the anchor bolts.

[0045] In some embodiments, the first grounding point 21 is located at the free end of the first crossarm 13, the first conductor point 31 is located at the free end of the third crossarm 15, the second grounding point 22 is located at the free end of the second crossarm 14, the second conductor point 32 is located at the free end of the fourth crossarm 161, and the third conductor point 33 is located on the lowest fifth crossarm 17 among a plurality of fifth crossarms 17, and the third conductor point 33 is located in the middle of the fifth crossarm 17. Specifically, as shown... Figure 1 As shown, the first ground wire suspension point 21 is located at the left end of the first crossarm 13, the first conductor suspension point 31 is located at the left end of the third crossarm 15, the second ground wire suspension point 22 is located at the right end of the second crossarm 14, and the second conductor suspension point 32 is located at the right end of the fourth crossarm 161. Since there are no other components below the fifth crossarm 17, it is convenient to install the third conductor on the third conductor suspension point 33. The third conductor suspension point 33 is located in the middle of the fifth crossarm 17. The electrical clearance of the third conductor can determine the distance between the first column and the second column and the length of the crossbeam 5, thus making the single-circuit landscape tower 100 more reasonably set up.

[0046] In some embodiments, the single-loop landscape tower 100 further includes a first decorative element 8, a second decorative element 9, a third decorative element 10, and a fourth decorative element 101.

[0047] The first decorative element 8 is located below and connected to the third crossbar 153, and is located on the side of the first main bar 11 away from the second main bar 12. The second decorative element 9 is located below and connected to the fifth crossbar 17, and is located on the side of the first main bar 11 adjacent to the second main bar 12. Specifically, as shown... Figure 1 As shown, both the first decorative piece 8 and the second decorative piece 9 can be reinforcing plates, and decorative patterns can be engraved on the reinforcing plates. The first decorative piece 8 is fixed to the lower right end of the third crossbar 153 and is fixed to the first main rod 11 with the right end of the first decorative piece 8. The second decorative piece 9 is fixed to the lower left end of the fifth crossbar 17 and is fixed to the first main rod 11 with the left end of the second decorative piece 9. Thus, the first decorative piece 8 and the second decorative piece 9 serve to decorate the tower body 1, and the first decorative piece 8 can support the third crossbar 153, while the second decorative piece 9 supports the left end of the fifth crossbar 162.

[0048] The third decorative element 10 is located below and connected to the sixth crossbar 163. The third decorative element 10 is located on the side of the second main bar 12 away from the first main bar 11. The fourth decorative element 101 is located below and connected to the fifth crossbar 17. The fourth decorative element 101 is located on the side of the second main bar 12 adjacent to the first main bar 11. Specifically, as... Figure 1 As shown, both the third decorative piece 10 and the fourth decorative piece 101 can be reinforcing plates, and decorative patterns can be engraved on the reinforcing plates. The third decorative piece 10 is fixed to the lower left end of the sixth crossbar 163 and the right end of the third decorative piece 10 is fixed to the second main rod 12. The fourth decorative piece 101 is fixed to the lower right end of the fifth crossarm 17 and the right end of the fourth decorative piece 101 is fixed to the first main rod 11. Thus, the third decorative piece 10 and the fourth decorative piece 101 serve a decorative function on the tower body 1, and the third decorative piece 10 can support the sixth crossbar 163, while the fourth decorative piece 101 supports the right end of the third crossarm 15.

[0049] In some embodiments, the single-loop landscape tower 100 further includes a plurality of crossbeams 5, which are spaced apart in the vertical direction and positioned above the fifth crossbeam 17. One end of each crossbeam 5 is connected to the first section, and the other end of each crossbeam 5 is connected to the third section, such as... Figure 1 As shown, the number of multiple crossbeams 5 can be set according to the actual situation, for example: Figure 1As shown, the left end of each crossbeam 5 is connected to the first main rod 11 via a flange or insert plate, and the right end of each crossbeam 5 is connected to the second main rod 12 via a flange or insert plate. Thus, the first main rod 11 and the second main rod 12 are connected by multiple crossbeams 5, which also makes the tower body 1 more stable.

[0050] In some embodiments, the single-loop landscape tower 100 further includes a first support rod and a second support rod, which are located between and connected to the fifth crossarm 17 and the crossbeam 5. Specifically, as Figure 1 As shown, the first support rod and the second support rod are located between the fifth crossarm 17 and the lowest crossbeam 5 of the plurality of crossbeams 5. The upper ends of the first support rod and the second support rod are both welded to the lowest crossbeam 5 of the plurality of crossbeams 5, and the lower ends of the first support rod and the second support rod are both welded to the fifth crossarm 17. This further improves the stress performance and stability of the tower body 1.

[0051] In some embodiments, the first and second segments can be connected by flanges, and the third and fourth segments can be connected by flanges. Therefore, when the first main rod 11 and the second main rod 12 are too long, they can be configured as two parts and detachably connected by flanges, according to actual needs. This facilitates the transportation of the first and second main rods 11 and 12, reduces the processing and manufacturing costs of the first and second main rods 11 and 12, and makes the arrangement of the first and second, third and fourth segments more reasonable.

[0052] The single-circuit tunneling landscape tower of this invention can be applied to power transmission line projects, especially in locations with tight transmission line corridors and where power lines cross each other. This invention employs a structure of a first main pole 11 and a second main pole 12, which avoids the disadvantage of increased land acquisition area caused by guy wire installations in related technologies. Especially in economically developed areas, guy wires may collide with existing buildings, structures, pipelines, etc., and the guy wire range increases the land acquisition area of ​​the tower, thus increasing the overall investment in the line.

[0053] Meanwhile, the tower height of a single-circuit tunneling landscape tower can be lower than the tower height in related technologies, enabling tunneling to be completed when the tunneling distance is insufficient due to height restrictions at many tunneling points. This avoids significant route adjustments and thus saves on engineering work.

[0054] Secondly, compared to the self-supporting iron towers in related technologies, although the installation of guy wires is eliminated, the single-base tower weight is relatively large due to its own structural characteristics. The new single-circuit drilling landscape tower adopts a structural form of steel pipe pole and steel pipe beam combination, which eliminates the cross diagonal beams, leg diagonal beams, and V-face beams of general iron towers, and has the advantage of reducing the amount of materials per base.

[0055] Finally, the unique "pavilion-style" structure can maximize the transformation of the power transmission line itself into a landscape feature, while also integrating it with the surrounding environment to the greatest extent possible. This allows the power transmission towers and lines to become works of art with aesthetic appeal, thus maximizing the satisfaction of the requirements of environmental impact assessment, water conservation, planning, and other departments, as well as the owners.

[0056] In summary, the single-circuit tunneling landscape tower of this invention combines the advantages of guyed towers and self-supporting towers (wine glass towers, cat-head towers, and T-shaped towers). Especially in locations with tight transmission line corridors and where power lines cross each other, it can be configured as a tunneling tower to tunnel under existing lines. This significantly reduces engineering investment and plays a very positive role in achieving our carbon peaking and carbon neutrality goals.
