Description

Technical Field

[0001] The invention relates to the field of power transmission and transformation line hardware, in particular to a length-adjustable power hardware bowl head hanging plate for high-voltage transmission lines. Background Art

[0002] In power transmission lines, bowl-shaped brackets play the role of suspending insulator strings and suspension clamps, and are subject to high working stress. Their safety performance is crucial to power transmission lines. However, current bowl-shaped brackets generally use W-shaped pins inside. The ball head of the W-shaped pin is prone to shaking in strong winds or other conditions, which can squeeze the W-shaped pin, causing it to deform or break, and then cause the ball head to fall off, affecting the safe operation of the line.

[0003] In order to solve the above problems, after searching, the Chinese patent with the announcement number CN213602375U discloses a bowl head hanging plate for power transmission line hardware, which includes a bowl head hanging plate body, a vertical hanging plate, a threaded rod, a rubber pad and a first nut. A support plate is installed inside the bowl head hanging plate body, and a first spring is installed on the upper side of the support plate. A buffer plate is provided on the upper side of the first spring, and the buffer plate is connected to the support plate through the first spring. A ball socket is provided inside the bowl head hanging plate body, and the upper side of the bowl head hanging plate body is provided with a ball socket. A bowl head seat is connected, a vertical hanging plate is provided on the lower side of the bowl head hanging plate body, a threaded rod is provided on the right side of the vertical hanging plate, a rubber pad is provided on the outside of the vertical hanging plate, a first nut is provided on the left side of the vertical hanging plate, a screw hole is provided inside the vertical hanging plate, an inlet hole is provided on the rear side of the bowl head seat, a second spring is provided at the end of the support plate, a groove is provided inside the bowl head seat, a second nut is provided inside the vertical hanging plate, a ball socket hole is provided on the upper side of the bowl head seat, and a ball head is provided on the upper side of the bowl head seat;

[0004] Although the above device can prevent the support plate from deforming and causing the ball head to fall off, the length of the hardware bowl head cannot be adjusted during actual use. During the actual installation process, due to differences in different transmission line structures, tower spacing, and insulator string lengths, if the length of the bowl head hanging plate cannot be adjusted, it may be difficult to accurately adapt to various specific installation scenarios, resulting in increased installation difficulty. It may even require additional auxiliary measures or modifications to other components to achieve correct installation, which will consume more manpower, material resources and time.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention utilizes conical interference seats. Multiple groups of equally spaced interference seats form a bowl-head hanging plate structure that prevents birds from resting and nesting on the plate, reducing the probability of short-circuit faults and ensuring the stability of power supply. The multiple equally spaced interference seats reduce the number of birds moving around nearby, thereby reducing the risk of insulation degradation due to bird droppings and other factors, and improving the insulation reliability of the line. The multiple equally spaced interference seats prevent birds from defecating on the bowl-head hanging plate, protecting the hardware from fecal corrosion and helping to maintain the good performance of the hardware.

[0018] 2. The present invention combines a bowl base and a hanging plate base to form a bowl head hanging plate. The length between the bowl base and the hanging plate base is adjusted by means of slots A, B, C, D, E and columns. Different transmission line projects may have differences in pole tower spacing, insulator string length and other aspects. Through the design of five groups of slots and columns, the length of the bowl head hanging plate can be flexibly adjusted according to actual installation requirements, which can quickly adapt to various installation scenarios, reduce the need to modify other components during the installation process, and improve installation efficiency. When the transmission line needs to be modified, upgraded or encounters special circumstances, such as changing the voltage level of the line, increasing the transmission capacity, etc., it may be necessary to adjust the length of the hardware. The adjustable structure enables the bowl head hanging plate to easily adapt to these changes without replacing the entire hardware, reducing the cost and workload of maintenance and upgrades, and improving the maintainability and scalability of the line.

[0019] 3. The present invention realizes multi-level adjustment by setting slots A, B, C, D and E, which can more accurately adjust the length of the bowl head hanging plate; different transmission line scenarios may have specific requirements for the length of the bowl head hanging plate. This multi-level adjustment can meet more detailed length adjustment needs, so that the bowl head hanging plate can better adapt to various specific working conditions and further optimize the overall performance of the line; the rebound of the squeezed spring is used to prompt the card column to be connected in the card slot, and the operation is relatively simple and convenient; when installing or adjusting the length of the bowl head hanging plate, it is only necessary to align the card column with the corresponding card slot, and the card connection can be quickly completed with the help of the elastic force of the spring, without the need for complicated tools or cumbersome operating procedures, thereby improving work efficiency.

[0030] Specific implementation method 1: Please refer to Figures 1-8 The present invention provides a technical solution: a length-adjustable power hardware bowl head hanging plate for high-voltage transmission lines, comprising a bowl seat 1, a fixing seat 4 is fixedly installed at the bottom of the bowl seat 1, a length step adjustment mechanism 7 is provided at the bottom of the fixing seat 4, a hanging plate seat 5 is provided at the bottom of the length step adjustment mechanism 7, a mounting hole 6 is provided on the hanging plate seat 5, a mounting groove 3 is provided inside the bowl seat 1, an insertion tube 701 is fixedly provided at one end of the length step adjustment mechanism 7, an adjustment seat 70 is fixedly provided at the other end of the length step adjustment mechanism 7, the end of the adjustment seat 70 is fixedly connected to the fixing seat 4, and the hanging plate seat 5 is welded and fixed to the bottom of the insertion tube 701.

[0031] Working principle: During actual use, multiple groups of equidistant interference seats 2 are evenly arranged on the outside of the bowl seat 1 and the fixed seat 4. The interference seats 2 are conical. Multiple groups of equidistant interference seats 2 form a bowl head hanging board to prevent birds from standing and building nests. When birds build nests near the bowl head hanging board, they often use branches, wires and other materials. These materials may come into contact with the power transmission line when the wind blows or the birds move, causing a short circuit in the line and causing a power outage. Multiple groups of equidistant interference seats 2 can prevent birds from staying and building nests on the bowl head hanging board, reducing the probability of short circuit failures and ensuring the stability of the power supply. Bird droppings or feathers may adhere to insulating components such as insulators, reducing their insulation performance and causing power outages. The flashover phenomenon occurs; after setting up multiple groups of equidistant interference seats 2, the activities of birds in the vicinity are reduced, thereby reducing the risk of insulation performance degradation due to bird droppings, etc., and improving the insulation reliability of the line; when birds perch, jump or peck on the hardware, they may cause wear and tear on the bowl head hanging plate and connected insulators and other equipment, affecting the mechanical strength and sealing performance of the equipment; multiple groups of equidistant interference seats 2 make it difficult for birds to approach, thereby reducing the wear and tear of the equipment caused by bird activities and extending the service life of the equipment; bird droppings are corrosive to a certain extent, and long-term accumulation on the surface of the hardware will accelerate the corrosion of the hardware and reduce its structural strength and conductivity; multiple groups of equidistant interference seats 2 can prevent birds from getting close Prevent birds from defecating on the bowl head hanging plate, protect the hardware from being corroded by feces, and help maintain the good performance of the hardware; the bowl seat 1 and the hanging plate seat 5 are combined together to form the bowl head hanging plate, and the length between the bowl seat 1 and the hanging plate seat 5 is adjusted by the slot A71, slot B711, slot C 72, slot D 73, slot E 74 and column 754; different transmission line projects may have differences in tower spacing, insulator string length, etc.; through the design of five groups of slots and columns 754, the length of the bowl head hanging plate can be flexibly adjusted according to actual installation requirements, which can quickly adapt to various installation scenarios, reduce the need to modify other components during the installation process, and improve installation efficiency; when the transmission line When modifications, upgrades, or special circumstances arise, such as changing the line voltage level or increasing transmission capacity, the length of the hardware may need to be adjusted. The adjustable structure allows the bowl head bracket to easily adapt to these changes without having to replace the entire hardware, reducing the cost and workload of maintenance and upgrades, and improving the maintainability and scalability of the line. The appropriate bowl head bracket length helps optimize the hanging angle and tension of the insulator string, thereby improving the electrical performance of the transmission line. The length adjustment through the five sets of slots and brackets 754 can more accurately control the position and status of the insulator string, reduce the discharge voltage of the insulator string, reduce the probability of flashover accidents, and ensure the safe and stable operation of the line.The bowl seat 1 and the hanging plate seat 5 are combined to form a bowl head hanging plate. The specific length adjustment method of the bowl head hanging plate is: hold the installation slot 3 and the hanging plate seat 5 with both hands respectively. The operator needs to wear gloves to avoid being stabbed by the interference seat 2. At the same time, pull the installation slot 3 outward so that the arc-shaped inner wall of the slot B711 squeezes the circumferential outer wall of the clamping column 754, so that the clamping column 754 moves outward and squeezes the spring 755 thereon. At the same time, the spring 755 is sleeved on the outside of the guide column 753. The setting of the guide column 753 can limit and guide the clamping column 754 during movement. , to ensure that the clamping column 754 does not tilt during movement. When the clamping column 754 and the clamping slot A71 are in a relative position, the squeezed spring 755 rebounds, prompting the clamping column 754 to be clamped inside the clamping slot A71, completing the first gear length adjustment of the bowl head hanging plate; the setting of the C clamping slot 72, the D clamping slot 73, and the E clamping slot 74 can achieve a total of multiple gears of adjustment for the bowl head hanging plate. The setting of the clamping slot A71, the clamping slot B711, the C clamping slot 72, the D clamping slot 73 and the E clamping slot 74 can achieve multiple gears of adjustment, which can more accurately adjust the length of the bowl head hanging plate; different The transmission line scenario may have specific requirements for the length of the bowl head hanging plate. This multi-speed adjustment can meet more detailed length adjustment needs, so that the bowl head hanging plate can better adapt to various specific working conditions and further optimize the overall performance of the line; the rebound of the squeezed spring 755 is used to prompt the clamping column 754 to be clamped in the clamping slot, and the operation is relatively simple and convenient; when installing or adjusting the length of the bowl head hanging plate, it is only necessary to align the clamping column 754 with the corresponding clamping slot, and the clamping can be quickly completed with the help of the elastic force of the spring 755, without the need for complicated tools or tedious operating procedures, thereby improving work efficiency; the rebound clamping of the spring 755 This method provides a relatively stable connection; the clamping column 754 is tightly locked into the clamping slot under the action of the spring 755, and is not easily loosened due to vibration or other external forces of the line. This ensures that the bowl head hanging plate remains stable after being adjusted to a specific length, thereby ensuring safe and reliable operation of the line. When the length of the bowl head hanging plate needs to be readjusted or maintained, it is also relatively easy to operate; simply overcome the elastic force of the spring 755 and remove the clamping column 754 from the clamping slot. You can then select a new clamping slot for connection as needed, or inspect and maintain components such as the spring 755, reducing maintenance costs and difficulty.
