Description

Technical Field

[0001] This utility model belongs to the field of basic equipment for power inspection, specifically relating to a tower joint structure and a support structure for the installation of machine nests on the tower. Background Technology

[0002] With the development and popularization of drones, drone applications are becoming more widespread. Currently, drone nests are mainly deployed in locations such as substations and rooftops, with fewer applications on power transmission and distribution line towers, mainly due to the inconvenience of tower maintenance and installation.

[0003] Currently, there are two locations for tower-mounted receivers: the top of the tower and the middle of the tower. The top-mounted receivers rely on the existing tower structure and have good communication, but deployment and installation are difficult, mainly because the deployment and installation process involves welding, hoisting components, etc.

[0004] The current search yielded a Chinese patent titled "Lightning Backflash Protection System for UAV Nests on Transmission Line Towers," publication number CN120389351A. This system, which provides insulation between the nest's outer shell and the tower, directly reduces the voltage at which lightning current reaches the nest, thus lowering the probability of backflash. Simultaneously, with the addition of a grounding terminal, the outer shell is directly connected to the tower's base down conductor. Any excess lightning current will be released through the down conductor, ensuring the nest's safety. However, this system only mentions that the steel support frame for the UAV nest is bolted to the tower, without disclosing the specific connection structure. The use of bolted connections presents issues of instability and unreliability.

[0005] In addition, Chinese Patent Publication No. CN218368347U discloses a drone recovery device installed on a steel tower, including a guide rail frame, a drone nest sliding mechanism, and a support frame. The guide rail frame includes steel frame guide rails and connecting beams. Two parallel steel frame guide rails are located on the same horizontal plane. Multiple connecting beams are evenly spaced along the length of the steel frame guide rails. The two ends of the connecting beams are respectively fixed to the lower ends of the two steel frame guide rails. The ends of the two steel frame guide rails are respectively fixed to the angle steel of the steel tower through a fixing frame. One end of the support frame is fixed to the middle of the two steel frame guide rails, and the other end is fixed to another angle steel of the steel tower through a fixing frame. The drone nest sliding mechanism includes a sliding base plate, sliding wheels, and a tensioning mechanism. The drone nest is fixed on the upper end of the sliding base plate. Multiple sliding wheels are rotatably arranged on both sides of the lower end of the sliding base plate, and the sliding wheels are in rolling contact with the steel frame guide rails. Multiple tensioning mechanisms are rotatably arranged on both sides of the lower end of the sliding base plate in the middle. Tensioning wheels are rotatably arranged on the outer ends of the tensioning mechanisms. The tensioning wheels are in rolling contact with the inner wall of the steel frame guide rails. This device has a complex structure and a long installation period. Utility Model Content

[0027] Figure 6 yes Figure 4 A partial view (i.e., a schematic diagram of the connection between the tower joint structure and the crossarm). Detailed Implementation

[0028] The tower joint structure A of this utility model includes at least a first pad 1, a first positioning piece 2, and a U-shaped rod 3.

[0029] The first pad 1 is installed at the inner corner of the tower support angle iron 4 (which can be the angle iron at the top of the tower or in the middle of the tower). The first positioning piece 2 is attached to the first surface 101 of the first pad 1. The first pad can be a rectangular pad or a frustum-shaped pad. The second surface 102 of the first pad, which is opposite to the first surface 101, abuts against the inner right angle surface of the tower support angle iron. Preferably, the first surface 101 and the second surface 102 of the first pad are parallel to each other, which is beneficial to the stability of the installation.

[0030] The first positioning piece 2 is a rectangular plate with a length longer than the width of the first pad. The portion extending beyond the first pad has two first through holes 201 for the two threaded rods of the U-shaped rod 3 to pass through. The first through hole 201 can be a round hole or a long strip hole.

[0031] The U-shaped rod 3 consists of two parallel threaded rods (at least threaded at the ends) and a middle rod. The middle rod is preferably perpendicular to the two threaded rods. The distance between the two threaded rods can be equal to the side width of the tower support angle iron 4. During assembly, the first pad 1 is flush with the side of the tower support angle iron 4 (i.e., the width of the first pad 1 is equal to the side width of the tower support angle iron 4 minus the wall thickness of the angle iron). This helps the two threaded rods to press firmly against the walls of the tower support angle iron 4 and the first pad 1, reducing shaking after installation.

[0032] A connector 5 (which can be a crossbeam, diagonal brace, or angle iron strip, or a rectangular flat iron) is attached to the outer surface 401 of the tower support angle iron 4, which is opposite to the first surface of the first pad block 1. The connector 5 has a corresponding second through hole 501 (which can be a round hole or an elongated hole). The two threaded rods of the U-shaped rod 3 pass through the first through hole and the second through hole in sequence and are fastened with bolts 11 (as in Embodiment 1). Figure 1(As shown).

[0033] The installation method of the first embodiment of the tower joint structure of this utility model involves first placing the first pad at the inner corner of the tower support angle iron, with the first positioning piece close to the first surface of the first pad, and the connector attached to the outer surface of the tower support angle iron. Then, the two threaded rods of the U-shaped rod pass through the first through hole and the second through hole in sequence and are tightened with bolts. This achieves the installation and fixation of the connector (which can be the crossarm and diagonal arm for installing the drone's nest) and the tower support angle iron (i.e., the angle iron at the top or middle of the tower). The installation is convenient and quick, and the use of the first pad and the first positioning piece ensures stable and reliable installation, preventing shaking.

[0034] To ensure stable and reliable installation, the first positioning piece 2 is provided with two bent pieces 202 that fasten to the first pad (the length of the bent pieces 202 is shorter than the length of the first positioning piece 2, and the bent pieces 202 and the first positioning piece 2 can be bent to form a 90-degree angle). By fastening the two bent pieces 202 to the first pad, the swing of the first positioning piece and the U-shaped rod can be restricted, thereby increasing the stability of the installation.

[0035] To further enhance the stability and reliability of the installation, one embodiment (e.g., Embodiment Two) is provided. Figure 2 As shown, a second pad 6 is attached to the outer surface 401 of the tower support angle iron 4 (the second pad can be a rectangular or frustum-shaped rubber or nylon block, and the second pad 6 is only attached to the outer surface 401 during installation). The outer side of the second pad 6 is attached to the connector 5. The distance between the two second through holes of the connector is greater than that of the second pad, so that the two threaded rods of the U-shaped rod can pass through the two sides of the second pad 6.

[0036] The installation method of Embodiment 2 of the tower joint structure of this utility model involves first placing the first pad at the inner corner of the tower support angle iron, with the first positioning piece close to the first surface of the first pad, and the second pad attached to the outer surface of the tower support angle iron. The connector is then attached to the outer surface of the second pad. Next, the two threaded rods of the U-shaped rod pass through the first and second through holes in sequence and are tightened with bolts. This achieves the installation and fixation of the connector (which can be the crossarm and diagonal arm for installing the drone's nest) to the tower support angle iron (i.e., the angle iron at the top or middle of the tower). The installation is convenient and quick, and the use of the first pad, second pad, and first positioning piece makes the installation more stable and reliable, less prone to shaking (e.g., ...). Figure 2 (As shown).

[0037] Another embodiment is (Embodiment 3, a preferred embodiment, such as...) Figure 3As shown): A second pad 6 is attached to the outer surface 401 of the tower support angle iron 4 (the second pad can be a rectangular or frustum-shaped rubber or nylon block, and the second pad 6 is only attached to the outer surface 401 during installation). A second positioning piece 7 with the same structure as the first positioning piece is provided between the outer side of the second pad 6 and the connector 5. The second positioning piece 7 also has a bent piece, which is fastened to the second pad to increase the stability of the installation. In this embodiment, the two threaded rods of the U-shaped rod pass through the first through hole on the first positioning piece 2, the first through hole on the second positioning piece 7 and the second through hole on the connector 5 in sequence, and are fastened with bolts 11.

[0038] The installation method of the third embodiment of the tower joint structure of this utility model is as follows: First, the first pad is placed at the inner corner of the tower support angle iron. The first positioning piece is close to the first surface of the first pad. The second pad is attached to the outer surface of the tower support angle iron. The second positioning piece is attached to the outer surface of the second pad. The connector is attached to the outer surface of the second positioning piece. Then, the two threaded rods of the U-shaped rod pass through the first through hole on the first positioning piece 2, the first through hole on the second positioning piece 7, and the second through hole on the connector 5 in sequence, and are tightened with bolts. This realizes the installation and fixation of the connector (which can be the crossarm and diagonal arm for installing the drone nest) to the tower support angle iron (i.e., the angle iron at the top or middle of the tower). The installation is convenient and quick. Moreover, the use of the first pad, the second pad, the first positioning piece, and the second positioning piece makes the installation more stable and reliable, and less prone to shaking.

[0039] The first and second pads can be made of rubber, nylon or metal, and the surfaces of the first and second pads are provided with stripes or grooves to increase friction.

[0040] The aforementioned bolts can be anti-vibration bolts.

[0041] This utility model relates to a support structure for mounting drone nests on a tower, comprising a crossarm 8 and a diagonal arm 9, both of which are connected at their inner ends to the tower support angle iron 4 (the crossarm 8 and diagonal arm 9 can be angle iron or rectangular flat iron). The outer ends of the diagonal arm are connected to the outer ends of the crossarm (by bolts). A drone nest 10 is mounted on the outer end of the crossarm (the drone nest 10 is an existing structure and will not be described in detail here). The inner ends of the diagonal arm and the crossarm are respectively connected by a tower joint structure A (the specific construction of the tower joint structure A is described above). In one embodiment, the diagonal arm and the crossarm are the connecting parts of the tower joint structure.

[0042] Another embodiment (such as) Figure 4 , 5 As shown in the preferred embodiment), the inner end of the diagonal brace is connected to the first end of a horizontally arranged angle iron strip 12 by bolts. The angle iron strip 12 serves as the connecting member, and the second through hole 501 is provided on the second end of the angle iron strip 12.

[0043] For secure installation, the crossarm 8 has two connections to the two tower support angle irons via tower joint structure A (e.g., Figure 4 (As shown).

[0044] Insulating pads can be placed between the housing and the crossarm to improve insulation performance, connect to the tower for grounding, and improve lightning protection capability; the above components can be galvanized iron, stainless steel, or other metal structures with anti-corrosion coatings on the surface.

[0045] The installation method of the tower-mounted machine nest support structure of this utility model involves connecting the outer ends of the crossarm and the diagonal arm (which can be done with bolts), and connecting and fixing the inner ends of the crossarm and the diagonal arm to the tower through the tower joint structure.

[0046] The tower-mounted machine nest installation support structure of this utility model has the following advantages:

[0047] 1. Modular design: The heaviest component weighs less than 20kg, which can be carried by a single person, making it easy to install and disassemble on the tower, reducing installation costs and time, and making it easy to adjust.

[0048] 2. Flexible deployment: By adjusting the supporting structure, it can be adapted to different sizes.

[0049] 3. Safe and reliable: The triangular support structure is stable and reliable, and the tower joint structure can enhance the structural stability, realize a firm connection between the tower body and the machine nest, and prevent the machine nest from loosening or falling off during long-term use.

[0050] 4. Corrosion protection design: Improve corrosion resistance by spraying water-repellent coatings such as RTV on the surface or using stable base materials such as stainless steel.

[0051] 5. Lightning protection design: The connection between the support structure and the housing is improved by grounding and supporting insulators to enhance lightning protection performance.
