Description

Technical Field

[0001] This application relates to the field of power operation and maintenance technology, specifically to an adjustable feeder terminal installation structure. Background Technology

[0002] 10kV integrated primary and secondary circuit breakers are common equipment in distribution lines, mainly used for segmentation and connection of 10kV distribution lines. They consist of vacuum circuit breakers, feeder terminals, and power supply PTs. Feeder terminals are an important component for automation and are often installed high on poles. After on-site installation, the feeder terminals are kept fixed, with the control panel facing the ground to avoid direct rain impact.

[0003] During the inspection of feeder terminals, maintenance personnel need to climb up the tower to inspect the feeder terminals. Since the feeder terminal panel faces downwards, maintenance personnel need to bend their bodies and look up to operate, which can easily cause physical fatigue and requires time to move around. The efficiency of maintenance also needs to be improved. Summary of the Invention

[0004] This application provides an adjustable feeder terminal installation structure, in which the component connecting the feeder terminal to the tower is configured to rotate automatically when a trigger condition is met, thereby changing the orientation of the feeder terminal's panel. This eliminates the need for maintenance personnel to bend over or look up during operation, saving overall maintenance time and improving maintenance efficiency.

[0005] This application is achieved through the following technical solution:

[0006] An adjustable feeder terminal mounting structure includes:

[0007] First connecting disk;

[0008] The second connecting plate is rotatably connected to the first connecting plate via a first connecting shaft. The second connecting plate also has a second connecting shaft for connecting the feeder terminal so that the feeder terminal and the second connecting plate rotate synchronously. The second connecting shaft is eccentrically arranged relative to the first connecting shaft.

[0009] A self-driven rotating assembly is connected between the first connecting plate and the second connecting plate to give the second connecting plate a rotational tendency relative to the first connecting plate;

[0010] A limiting component, which is connected to the first connecting plate and cooperates with the second connecting plate to limit the rotation of the second connecting plate;

[0011] The limiting component is controlled to release its rotational limitation on the second connecting plate.

[0012] The adjustable feeder terminal installation structure provided in this application allows the feeder terminal to swing relative to the first rotating shaft by rotating the second connecting plate and the first connecting plate. This changes the orientation of the feeder terminal control panel, allowing maintenance personnel to inspect the control panel from the side of the feeder terminal with minimal or no bending over. Furthermore, since the workers are primarily engaged in high-altitude operations, the self-driven rotation component in this application allows maintenance personnel to automatically change the orientation of the feeder terminal control panel by operating the limit component with one hand, ensuring the safety of the maintenance personnel.

[0013] In some optional embodiments, the self-driven rotation assembly includes:

[0014] An arc-shaped guide rod is connected to the first connecting disc, and the center of curvature of the arc-shaped guide rod is located on the axis of the first rotating shaft;

[0016] An elastic element is connected between the sliding sleeve and the arc-shaped guide rod to give the sliding sleeve a sliding tendency relative to the arc-shaped guide rod.

[0017] In some optional embodiments, the number of sliding sleeves is multiple and they are arranged at equal intervals, and each sliding sleeve is connected to the arc-shaped guide rod by an elastic element.

[0018] In some alternative embodiments, the elastic element is configured as a compression spring.

[0019] In some optional embodiments, a multi-unit buffer assembly is also included, which is connected to the first connecting disk;

[0020] A trigger element is connected to the second connecting disk;

[0021] When the second connecting plate rotates relative to the first connecting plate, the trigger contacts different parts of the multi-link buffer assembly to obtain different levels of buffering force.

[0022] In some optional embodiments, the multi-link buffer assembly includes multiple elastic telescopic members connected to the first connecting plate. The telescopic direction of the elastic telescopic members is parallel to the axis of the first rotating shaft. Along the circumference of the first rotating shaft, the required telescopic driving force of the multiple elastic telescopic members decreases or increases sequentially.

[0023] The trigger element is a hemisphere.

[0024] In some alternative embodiments, the movable end of the elastic telescopic member is fitted with a ball bearing for contacting the trigger member via a grooved ball-locking process.

[0025] In some optional embodiments, the limiting component includes:

[0026] A torsion shaft is movably mounted on the first connecting plate and elastically slidably connected to the first connecting plate;

[0027] A limiting protrusion is provided, which is connected to one end of the torsion shaft, and the length direction of the limiting protrusion coincides with the radial direction of the torsion shaft.

[0028] The second connecting plate has an arc-shaped groove, the center of curvature of which is located on the first rotating shaft. The arc-shaped groove has a T-shaped groove on its arc-shaped wall, which includes a first section and a second section. The length direction of the first section is perpendicular to the bottom surface of the arc-shaped groove, and the length direction of the second section is parallel to the length direction of the arc-shaped groove.

Furthermore, since the workers are primarily engaged in high-altitude operations, the self-driven rotation component in this application allows maintenance personnel to automatically change the orientation of the feeder terminal control panel by operating the limit component with one hand, ensuring the safety of the maintenance personnel.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0041] Please refer to the following: Figures 1-4 This application provides an adjustable feeder terminal mounting structure, which includes a first connecting plate 100, a second connecting plate 200, a self-driven rotation component 300, and a limiting component 400. The second connecting plate 200 is rotatably connected to the first connecting plate 100 via a first connecting shaft. The second connecting plate 200 also has a second connecting shaft for connecting the feeder terminal so that the feeder terminal and the second connecting plate 200 rotate synchronously. The second connecting shaft is eccentrically arranged relative to the first connecting shaft. The self-driven rotation component 300 is connected between the first connecting plate 100 and the second connecting plate 200 so that the second connecting plate 200 has a rotational tendency relative to the first connecting plate 100. The limiting component 400 is connected to the first connecting plate 100 and cooperates with the second connecting plate 200 to restrict the rotation of the second connecting plate 200. The limiting component 400 is controlled to release its rotational limitation on the second connecting plate 200.

[0042] In this embodiment, both the first connecting plate 100 and the second connecting plate 200 are circular plates, and their sizes can be designed to be the same. In other embodiments, if the second connecting plate 200 is required to have a large swing amplitude, the first connecting plate 100 can also be designed as a cam plate or other irregular shapes. The first connecting plate 100 is used to connect the tower.

[0043] In this embodiment of the application, before maintenance, the first connecting plate 100 and the second connecting plate 200 are axially aligned, and at this time the second connecting plate 200 has a rotational tendency under the action of the self-driven rotating component 300.

[0044] During maintenance, the maintenance personnel climb to the side of the feeder terminal and operate the limiting component 400 with one hand to release the rotation limit of the second connecting plate 200. The second connecting plate 200 then rotates automatically under the action of the self-driven rotation component 300, causing the feeder terminal to rotate synchronously. This changes the orientation of the feeder terminal's control panel, allowing the maintenance personnel to view the control panel at approximately eye level and perform maintenance. After maintenance, because the second rotating shaft is eccentrically arranged relative to the first rotating shaft, the maintenance personnel can directly push the feeder terminal or the second connecting plate 200. The second connecting plate 200 overcomes the reaction force of the self-driven rotation component 300 and rotates relative to the first connecting plate 100. Once in position, the limiting component 400 re-limits the second connecting plate 200, preventing accidental swinging of the feeder terminal.

[0045] It should be noted that the limiting component 400 in this embodiment is an automatically resettable limiting component 400, such as the door and window spring lock used in daily life. Of course, other structures with the same principle as door and window spring locks can also be used. Such structures are widely disclosed in the prior art and will not be described in detail here.

[0046] The adjustable feeder terminal installation structure provided in this application embodiment allows the feeder terminal to swing relative to the first rotating shaft by rotating the second connecting plate 200 and the first connecting plate 100. This changes the orientation of the feeder terminal control panel, allowing maintenance personnel to inspect the feeder terminal control panel from the side with a near-level view, without having to bend over or with a reduced bending angle. Furthermore, since the workers are primarily engaged in high-altitude operations, the self-driven rotating component 300 allows maintenance personnel to automatically change the orientation of the feeder terminal control panel by operating the limiting component 400 with one hand, ensuring the safety of the maintenance personnel.

[0047] In one specific embodiment of the self-driven rotation assembly 300, the self-driven rotation assembly 300 includes an arc-shaped guide rod 301, a sliding sleeve 302, and an elastic element 303. The arc-shaped guide rod 301 is connected to the first connecting disk 100, and the center of curvature of the arc-shaped guide rod 301 is located on the axis of the first rotating shaft. The arc-shaped guide rod 301 is a round rod, and its length direction is parallel to the disk surface of the first connecting disk 100. The arc-shaped guide rod 301 is located between the first connecting disk 100 and the second connecting disk 200, and there is a gap between the arc-shaped guide rod 301 and the first connecting disk 100. The two ends and the middle of the arc-shaped guide rod 301 can be fixedly connected to the first connecting disk 100 through connecting posts. The sliding sleeve 302 is sleeved on the arc-shaped guide rod 301 to... To form a sliding fit, the sliding sleeve 302 is an arc-shaped cylinder. Multiple balls can be installed on the inner wall of the sliding sleeve 302 using a grooved ball-locking process to improve the smoothness of sliding between the sliding sleeve 302 and the arc-shaped guide rod 301. In practice, an arc-shaped cylindrical steel ball retainer can be fabricated first, and then the steel ball retainer can be inserted into the cylindrical structure and fixedly connected to form the sliding sleeve 302. The elastic element 303 is connected between the sliding sleeve 302 and the arc-shaped guide rod 301 to give the sliding sleeve 302 a sliding tendency relative to the arc-shaped guide rod 301. The elastic element 303 can be specifically designed as a compression spring, sleeved on the arc-shaped guide rod 301. Of course, a shoulder can be provided on the arc-shaped guide rod 301 to limit the movement of the elastic element 303, or one end of the elastic element 303 can be directly fixedly connected to the arc-shaped guide rod 301.

[0048] In some optional embodiments, the number of sliding sleeves 302 is multiple and equidistantly arranged, and each sliding sleeve 302 is connected to an elastic element 303 between itself and the arc-shaped guide rod 301. The multiple elastic elements 303 cooperate with each other to provide elastic force to the second connecting disc 200. Compared with using a single elastic element 303, the stiffness coefficient requirement of the elastic element 303 is reduced.

[0049] In some optional embodiments, a multi-stage buffer assembly 500 is also included, which is connected to the first connecting disk 100; wherein, a trigger 600 is connected to the second connecting disk 200; when the second connecting disk 200 rotates relative to the first connecting disk 100, the trigger 600 contacts different parts of the multi-stage buffer assembly 500 to obtain different levels of buffering force.

[0050] In this embodiment, the multi-stage buffer assembly 500 can provide multi-level buffering force to the second connecting plate 200. When the rotation limit of the second connecting plate 200 is released, the elastic potential energy stored in the elastic element 303 is at its maximum, and the multi-stage buffer assembly 500 provides a large buffering force to the second connecting plate 200 to prevent the second connecting plate 200 from being ejected. During the rotation of the second connecting plate 200, the elastic element 303 gradually releases its elastic potential energy, and the multi-stage buffer assembly 500 provides a gradually decreasing buffering force to the second connecting plate 200 to ensure that the second connecting plate 200 can rotate to the predetermined position. In addition, when maintenance personnel push the feeder terminal, the multi-stage buffer assembly 500 can provide the maintenance personnel with a gradually increasing tactile sensation. That is, when the second connecting plate 200 is close to the initial position, the second connecting plate 200 rotates relatively slowly, which can avoid unnecessary collisions caused by excessive force.

[0051] Compared to using commonly used hydraulic rods as damping components, in this embodiment, if the second connecting plate 200 is suddenly subjected to excessive force, there will be no significant obstruction, and the human body will not suffer a large reverse impact force, thus ensuring the safety of high-altitude operations.

[0052] In some optional embodiments, the multi-link buffer assembly 500 includes multiple elastic telescopic members 501. Each elastic telescopic member 501 may include a guide cylinder and a guide rod, both of which are perpendicularly connected to the first connecting plate 100. The guide rod is inserted into the guide cylinder, and a spring is arranged between the guide rod and the guide cylinder to achieve elastic telescopic movement. That is, the telescopic direction of the elastic telescopic member 501 is parallel to the axis of the first rotating shaft. Along the circumference of the first rotating shaft, the required telescopic driving force of the multiple elastic telescopic members 501 decreases or increases sequentially. The trigger member 600 is a hemisphere.

[0053] In some alternative embodiments, the movable end of the elastic telescopic member 501 is fitted with a ball bearing for contacting the trigger member 600 via a grooved ball locking process.

[0054] This design reduces the resistance between the trigger 600 and the movable end of the elastic telescopic member 501, making the elastic rotation of the second connecting plate 200 smoother.

[0055] In some optional embodiments, the limiting component 400 includes a torsion shaft 401 and a limiting protrusion 402; the torsion shaft 401 is movably mounted on the first connecting plate 100 and elastically slidably connected to the first connecting plate 100; the limiting protrusion 402 is connected to one end of the torsion shaft 401, and the length direction of the limiting protrusion 402 coincides with the radial direction of the torsion shaft 401; wherein, the second connecting plate 200 is provided with an arc-shaped groove 201, the curvature center of the arc-shaped groove 201 is located on the first rotating shaft, and a T-shaped groove 202 is provided on the arc-shaped wall of the arc-shaped groove 201, the T-shaped groove 202 includes a first segment and a second segment, the length direction of the first segment is perpendicular to the bottom surface of the arc-shaped groove 201, and the length direction of the second segment is parallel to the length direction of the arc-shaped groove 201.

[0056] In the initial state, the limiting protrusion 402 is located in the first section of the T-slot 202, and the limiting protrusion 402 will form a rotational limit on the second connecting plate 200. When the torsion shaft 401 is pressed, the limiting protrusion 402 will enter the junction of the first and second sections. Under the elastic force of the elastic element 303, the second connecting plate 200 will rotate on its own, and the limiting protrusion 402 will enter the second section. The two side walls of the second section will form a sliding limit on the torsion shaft 401 through the limiting protrusion 402. When the second connecting plate 200 is pushed manually, the limiting protrusion 402 will return to the junction of the first and second sections. At this time, the T-slot 202 will no longer form a sliding limit on the torsion shaft 401, and the torsion shaft 401 will elastically slide so that the limiting protrusion 402 is located in the first section. The limiting protrusion 402 will then re-form a rotational limit on the second connecting plate 200.

[0057] In some alternative embodiments, the limiting protrusion 402 is provided with a rolling structure. The rolling structure can be a smooth coating, a roller, a ball, etc., and preferably, the rolling structure is set as a ball.
