Description

Technical Field

[0001] The utility model relates to the technical field of AC isolating switches, in particular to an auxiliary operating mechanism for an AC isolating switch. Background Art

[0002] High-voltage disconnectors are important switching electrical appliances in the electrical systems of power plants and substations. Their main functions are to ensure the safety of high-voltage electrical appliances and devices during maintenance work and to isolate the voltage. The control of high-voltage disconnectors generally adopts an operating mechanism box. The operating mechanism box is divided into manual and electric types. The operating mechanism box is connected to the connecting rod on the high-voltage disconnector. The connecting rod of the high-voltage disconnector rotates with the connecting part of the operating mechanism to realize the opening and closing of the high-voltage disconnector. The existing high-voltage disconnectors require the use of auxiliary operating mechanisms. For workers of different heights, it will cause discomfort during the control process, which may lead to accidents due to improper operation of the workers. For this reason, we propose an auxiliary operating mechanism for the high-voltage AC disconnector box.

[0003] The existing authorization announcement number is CN 214898216 U, "A high-voltage AC disconnector operating mechanism box auxiliary operating mechanism", which includes: a base, the top of the base is fixedly connected to auxiliary telescopic rods on all sides, the top of the auxiliary telescopic rod is movably connected to a movable block, and the top of the movable block is movably connected to an operating table. The utility model uses an operating table, a high-voltage AC disconnector body, a baffle, mounting bolts, a servo motor, a turntable, a limit block, a movable rod and a clamping block in combination, so that after the high-voltage AC disconnector body is positioned by the fixed block, the baffle and the mounting bolts are installed on the surface of the fixed block, the turntable is driven by the servo motor so that the limit block drives the movable rod to move upward, and the operating table is lifted up by the movable rod, thereby solving the problem that the existing high-voltage disconnector needs to use an auxiliary operating mechanism, which causes discomfort to workers of different heights during the control process, leading to accidents caused by improper operation of the workers.

[0004] While the above description addresses the problem of existing high-voltage disconnectors requiring auxiliary operating mechanisms by raising the operating table through a movable lever, this can cause discomfort for workers of varying heights, leading to accidents caused by improper operation. However, since AC disconnectors come in a variety of sizes, these sizes may differ. For example, if the device cannot adjust the position of the fixing plate and the clamping block, multiple devices of different sizes may be required to accommodate different AC disconnector sizes. This requires different operating devices for each AC disconnector, necessitating the purchase and maintenance of multiple device models. This increases inventory costs and potentially increases operating and maintenance costs. Utility Model Content

This design provides a stable support frame that can not only withstand the vibration and pressure during equipment operation, ensuring the stability and safety of the equipment, but also the combination of the support plate and mounting plate not only provides solid support, but also effectively utilizes the space inside the equipment. This is a significant advantage for equipment designers, allowing them to optimize the overall structure and layout of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Adjusting mechanism 3, including fixed shell 31, fixed shell 31 bottom is provided with support mechanism 4, fixed shell 31 one side is provided with machine shell 32, the inner wall of machine shell 32 is connected with motor 33, the output shaft one end of motor 33 is connected with threaded rod 34, the other end surface of threaded rod 34 is provided with fixed ring 35, the both ends surface of threaded rod 34 is connected with positive screw nut 36 and reverse screw nut 37 respectively, the top surface of positive screw nut 36 and reverse screw nut 37 is provided with connecting frame 38, the top of two connecting frames 38 is provided with fixed plate 39, the inner side of two fixed plates 39 is provided with clamping block 310.

[0031] In the embodiment, machine shell 32 one side is connected in fixed shell 31 one side by bolt thread, motor 33 surface is fixedly connected in the inner wall of machine shell 32, threaded rod 34 one end is fixedly connected in the output shaft one end of motor 33, threaded rod 34 other end is rotatably connected in the inner wall of fixed ring 35, fixed ring 35 one side is fixedly connected in the side of fixed shell 31 away from motor 33, the thread groove of the inner wall of positive screw nut 36 and reverse screw nut 37 is respectively threadedly connected in the both ends surface of threaded rod 34, the top surface of two connecting frames 38 is respectively fixedly connected in the top surface of positive screw nut 36 and reverse screw nut 37, the surface of two connecting frames 38 is slidably connected in the inner wall of the sliding slot of fixed shell 31 top, the bottom of two fixed plates 39 is respectively fixedly connected in the top of corresponding connecting frame 38, the one side of two clamping blocks 310 is respectively fixedly connected in the one side of corresponding fixed plate 39, and cooperation is carried out by the above components;Since ac disconnecting switch exists multiple specifications and sizes, the design of the auxiliary operating mechanism not only allows to adjust the movement of motor 33 and threaded rod 34, adapts to different specifications of switch body. This flexibility makes the same set of operating mechanism can also be used for different models of switch, reduces the complexity of inventory and maintenance, and simultaneously through the collaborative movement of motor 33, threaded rod 34 and nut, operator can also accurately control the movement of positive screw nut 36 and reverse screw nut 37 on threaded rod 34. This accuracy can ensure the accurate opening and closing of switch, especially for large or high-voltage equipment, to ensure safety and reliability.

[0032] Embodiment 2

[0033] As Figure 1-Figure 2 As shown, support mechanism 4 includes support plate 41, fixed shell 31 bottom is fixedly connected in the top of support plate 41, support plate 41 bottom both sides are fixedly connected with mounting plate 42.

[0034] In this embodiment, the bottom of the fixed housing 31 is connected to the top of the support plate 41.

[0035] Working principle:

[0036] like Figures 1-4 As shown, since the AC isolating switch body 1 has a variety of specifications, different specifications may result in different sizes. When using different AC isolating switch bodies 1, the staff can first start the motor 33. When the motor 33 is started, its output shaft will drive the threaded rod 34, and the threaded rod 34 will rotate by cooperating with the fixing ring 35. When the threaded rod 34 rotates, it will also synchronously drive the forward nut 36 and the reverse nut 37. Since the inner wall of the forward nut 36 is provided with a forward thread groove, and the inner wall of the reverse nut 37 is provided with a reverse thread groove, this will cause the surface thread of the threaded rod 34 to rotate with the forward nut 36 and the reverse nut 37. The thread grooves formed on the nut 37 cooperate with each other, so that the forward nut 36 and the reverse nut 37 can simultaneously approach the two ends or the middle section of the threaded rod 34, and the forward nut 36 and the reverse nut 37 will also synchronously drive the connecting frame 38, the fixing plate 39 and other components to move when they move. However, because the connecting frame 38 is limited to the inner wall of the sliding groove formed on the top of the fixing shell 31, the forward nut 36 and the reverse nut 37 can only continue to move but cannot rotate. The staff can adjust the position of the fixing plate 39 and the block 310 by starting the motor 33 according to the actual situation, so that the block 310 is stuck in the slot 2 formed on both sides of the AC isolating switch body 1 for use.

[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Within the scope of the present invention, the technical features of the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0038] The present invention is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
