Description

Technical Field

[0001] This utility model relates to the field of power transmission line technology, specifically a compact angle steel tower structure for a 220kV single-circuit power transmission line. Background Technology

[0002] Transmission angle steel towers are steel structure towers made primarily of angle steel. They are an indispensable and important component of power transmission and distribution systems, mainly used for erecting high-voltage transmission lines.

[0003] A search revealed that the patent, CN218375658U, entitled "A Utility Model of a New Type of Angle Steel Tower for Transmission Lines," includes an angle steel tower body, a mounting base, and a support base. Research and analysis revealed that while it offers advantages such as convenient adjustment of the line direction during use without needing to remove the fixing of the angle steel tower body or readjust the position of the support base, and low difficulty in subsequent adjustments, it also has the following disadvantages to some extent.

[0004] For example, because the angle steel of the tower is distributed in a regular stepped pattern and no anti-climbing device is installed, it is easy for unauthorized personnel to climb it by taking advantage of the gaps between the angle steel. This not only directly threatens the personal safety of climbers and causes high-altitude fall injuries and deaths, but also seriously affects the normal operation of the transmission line. At the same time, unauthorized personnel entering the transmission line protection zone may also cause electric shock accidents due to illegal operations, which brings dual harm to the safe and stable operation of the power system and public safety. In order to solve the above technical problems, we have designed a compact angle steel tower structure for a 220kV single-circuit transmission line. Utility Model Content

[0005] The purpose of this utility model is to provide a compact angle steel tower structure for a 220kV single-circuit transmission line, which has the advantage of anti-climbing function. It solves the problem that existing transmission angle steel towers are easily climbed by unauthorized personnel by taking advantage of the gaps between the angle steels because the angle steels of the tower body are distributed in a regular stepped shape and no anti-climbing device is installed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a compact angle steel tower structure for a 220kV single-circuit transmission line, comprising a base, a tower body fixedly connected to the top of the base, a conical plate fixedly fitted to the bottom of the surface of the tower body, a conical block movably connected to the right side of the conical plate, a locking block riveted to the left side of the bottom of the conical block, a locking buckle adapted to the locking block riveted to the right side of the bottom of the conical plate, a frame connected to the top of the tower body by bolts, a waterproof motor connected to the front side of the frame by bolts, the output end of the waterproof motor penetrating into the interior of the frame and connected to a drum by bolts, a cable wound around the surface of the drum, and an ultrasonic bird repeller connected to the bottom end of the cable by bolts.

[0007] Preferably, guide ropes are bolted to the front and rear sides of the bottom of the frame, and guide cylinders are movably sleeved on the surface of the guide ropes. The opposite sides of the guide cylinders are bolted to the ultrasonic bird repeller, and the bottom of the guide ropes is bolted to the base.

[0008] Preferably, the bottom of the frame has an elongated hole, and the bottom end of the cable passes through the elongated hole.

[0009] Preferably, guide grooves are provided on both the front and rear sides of the conical plate, and guide blocks are riveted to both the front and rear sides of the conical block, with the opposite side of each guide block extending into the inner cavity of the guide groove.

[0010] Preferably, the rear side of the drum is movably connected to the inner wall of the frame by bolts, and the bottom of the conical block is provided with a groove.

[0011] Preferably, cable brackets are bolted to the top of both sides of the tower body, and the left side of the locking block extends into the interior of the latch.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model has the advantage of anti-climbing function through the cooperation of conical plate, conical block, locking block and buckle. Under the action of the conical plate, it can block irrelevant personnel, so that they have no force point to climb and cannot continue to climb upward. When the staff needs to climb for maintenance, they can use the key to remove the lock on the surface of the buckle and locking block, and then push the conical block to the right to remove the conical block, and then continue to climb upward.

[0013] 2. This utility model has the advantage of bird deterrence function through the combination of frame, waterproof motor, drum, cable and ultrasonic bird deterrent. The external controller controls the operation of waterproof motor and ultrasonic bird deterrent. The output end of waterproof motor drives drum to rotate, and drum releases cable. At this time, ultrasonic bird deterrent moves downward inside tower body, so as to deter birds from nesting at different positions of tower body. Attached Figure Description

[0016] Please see Figures 1-7A compact angle steel tower structure for a 220kV single-circuit transmission line includes a base 1, with a tower body 2 fixedly connected to the top of the base 1. The tower body 2 serves as the main load-bearing structure of the transmission line. Employing a compact angle steel design, it significantly reduces the space occupied by the tower body 2 while ensuring sufficient mechanical strength and load-bearing capacity. A conical plate 3 is fixedly fitted onto the bottom surface of the tower body 2. The conical structure of the conical plate 3, with its irregular stress points, physically prevents unauthorized personnel from climbing the tower body 2 through the gaps in the angle steel, thus avoiding falls and injuries caused by unauthorized personnel climbing. It also prevents unauthorized personnel from climbing the tower body 2. Entering the transmission line protection zone for unauthorized operations reduces the risk of electric shock accidents and ensures the safe and stable operation of the power system and public safety. A conical block 4 is movably connected to the right side of the conical plate 3. By setting the conical block 4, it cooperates with the conical plate 3 to form a complete anti-climb protection structure, filling the opening area on the right side of the conical plate 3 and ensuring no loopholes in the anti-climb protection. When workers are performing maintenance, they can remove the conical block 4 to continue climbing the angle steel tower. A locking block 5 is riveted to the left side of the bottom of the conical block 4, and a locking buckle 6, which matches the locking block 5, is riveted to the right side of the bottom of the conical plate 3. The locking buckle 6 and the locking block 5 work together to form a locking mechanism. The mechanism allows the cone block 4 to be fixed to the cone plate 3 via external locking after installation, preventing unauthorized personnel from moving or removing the cone block 4 and further enhancing the security of the anti-climb protection. The top of the tower body 2 is bolted to a frame 7, and a waterproof motor 8 is bolted to the front of the frame 7. The waterproof motor 8 serves as the power source for the bird deterrent system, driving the drum 9 to rotate, releasing and retrieving the cable 10, and controlling the up-and-down movement of the ultrasonic bird deterrent 11 inside the tower body 2. This provides power support for the ultrasonic bird deterrent 11 to cover different locations on the tower body 2, ensuring comprehensive bird deterrence coverage. The waterproof motor 8 is a Y2-80M1-2 type waterproof three-phase asynchronous motor. The output end of the waterproof motor 8 extends into the interior of the frame 7 and is connected to a drum 9 by bolts. A cable 10 is wound around the surface of the drum 9. An ultrasonic bird repeller 11 is connected to the bottom of the cable 10 by bolts. By setting the ultrasonic bird repeller 11, birds are driven away by emitting ultrasonic waves, preventing birds from nesting on the tower 2. Moreover, the ultrasonic frequency is outside the range of human hearing and will not cause noise interference to the surrounding residents. The ultrasonic bird repeller 11 is a DB-200A type high-voltage transmission line special ultrasonic bird repeller.

[0017] Please see Figure 1 , Figure 2 and Figure 7Guide ropes 12 are bolted to the front and rear sides of the bottom of the frame 7. By setting the guide ropes 12 and guide cylinders 13, the two work together to provide guidance for the movement of the ultrasonic bird repeller 11, so as to prevent the ultrasonic bird repeller 11 from deviating or shaking due to wind or other external forces during the up and down movement, and ensure that it always moves along the preset path inside the tower 2 to accurately cover the bird repeller area. The guide cylinders 13 are movably sleeved on the surface of the guide ropes 12. The opposite side of the guide cylinders 13 is connected to the ultrasonic bird repeller 11 by bolts. The bottom of the guide ropes 12 is connected to the base 1 by bolts.

[0018] Please see Figure 6 The bottom of the frame 7 has an elongated hole 14 through which the bottom end of the cable 10 passes.

[0019] Please see Figure 4 and Figure 5 The front and rear sides of the conical plate 3 are provided with guide grooves 15, and the front and rear sides of the conical block 4 are riveted with guide blocks 16. By setting the guide grooves 15 and guide blocks 16, the two work together to provide guidance and limit the left and right movement of the conical block 4, ensuring that the conical block 4 moves along a fixed trajectory when installed or removed, avoiding deviation that would prevent precise docking or locking. The opposite side of the guide blocks 16 extends into the inner cavity of the guide grooves 15.

[0020] Please see Figure 4 and Figure 6 The rear side of the drum 9 is movably connected to the inner wall of the frame 7 by bolts, and the bottom of the cone block 4 is provided with a groove.

[0021] Please see Figure 1 and Figure 3 The top of both sides of the tower body 2 is connected to cable brackets 17 by bolts. By setting up cable brackets 17, the 220kV single-circuit transmission cable can be supported and fixed, and the cable can be erected according to the design height and spacing. This prevents the cable from sag due to its own weight or swaying due to wind force, and ensures that the cable and the tower body 2, and the cable and the cable maintain a safe distance, so as to prevent short circuit accidents caused by cable contact or collision. The left side of the locking block 5 extends into the inside of the locking buckle 6.

[0022] In use, locks are installed on the surfaces of the latch 6 and the locking block 5. During daily use, the cone plate 3 can block unauthorized personnel, preventing them from having a point of leverage for climbing and thus preventing them from climbing further. When staff need to climb for maintenance, they can use a key to remove the locks on the surfaces of the latch 6 and the locking block 5, and then push the cone block 4 to the right. After removing the cone block 4, they can continue to climb. When bird deterrence is required, the external controller controls the waterproof motor 8 and the ultrasonic bird deterrent 11 to work. The output end of the waterproof motor 8 drives the drum 9 to rotate, and the drum 9 releases the cable 10. At this time, the ultrasonic bird deterrent 11 moves downward inside the tower body 2, thereby enabling ultrasonic bird deterrence at different locations on the tower body 2 to prevent birds from nesting.

[0023] In summary, the compact angle steel tower structure of this 220kV single-circuit transmission line, through the cooperation of conical plate 3, conical block 4, locking block 5, locking buckle 6, frame 7, waterproof motor 8, drum 9, cable 10 and ultrasonic bird repeller 11, solves the problem that existing transmission angle steel towers are easily climbed by unauthorized personnel by taking advantage of the gaps between the angle steels during use, due to the regular stepped distribution of the tower's angle steels and the lack of anti-climbing devices.
