Description
TECHNICAL FIELD
[0001] The utility model relates to electrical equipment technical field, especially a detachable knife switch mechanical locking device. BACKGROUND
[0002] The knife switch is one of very important components in the power system, in order to play the role of limiting the position of the knife switch, avoiding misoperation or preventing the misoperation of the knife switch during the operation of the knife switch, the knife switch locking rod is often set to limit the operation of the knife switch. Specifically, the knife switch can be locked when the knife switch locking rod is rotated to the vertical state, at this time the knife switch cannot be operated; and the knife switch can be unlocked when the knife switch locking rod is rotated to the horizontal state, at this time the knife switch can be operated. The knife switch locking ring is used to keep the knife switch locking rod in the vertical locking state, and the knife switch locking rod and the selected nearest auxiliary fixing are blocked at both ends by other equipment, so that the knife switch locking ring cannot be directly taken out, so that the knife switch locking rod cannot be directly rotated to separate from the auxiliary fixing to reach the horizontal state, thereby realizing the stable operation of the knife switch.
[0003] Then in the prior art, the knife switch locking rod is often bound with the nearest knife switch operation vertical main connecting rod, and the existing locking ring is a complete metal ring, as shown in Figure 1 The upper and lower ends of the knife switch locking rod and the vertical main connecting rod are blocked during normal use, so that the complete locking ring can only be disassembled by the arrow direction shown in the figure after the blocking of the upper and lower ends of the knife switch locking rod and the vertical main connecting rod is disassembled. When the maintenance personnel replace the locking ring, they need to remove the clamp under the vertical connecting rod, disassemble the knife switch operation vertical main connecting rod, and even cut the vertical connecting rod and re-weld it, so that the locking ring can be put in. The disassembly of the clamp also causes the knife switch to be misaligned, and the knife switch needs to be continuously adjusted to operate in the correct position. Therefore, the replacement of the knife switch locking ring must be carried out during power failure, and the replacement of the knife switch on the line side requires stopping the interval and the line, and the replacement of the knife switch on the bus side requires stopping the interval and the bus. In the case of high load, it is difficult to stop the line or even the bus, and the adjustment work of the knife switch after reassembly requires higher skill of the maintenance personnel, and it takes a long time. It takes about 20 minutes for two skilled workers to replace the knife switch locking ring and adjust the knife switch to the right position. In addition, during outdoor operation, the knife switch locking ring is prone to rust and even breakage, causing the knife switch to misalign, heat and even cause the accident of pulling the knife switch with electricity during operation.

[0033] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0034] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.
[0035] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.
[0036] Embodiment 1
[0037] Referring to Figure 2 and Figure 3 For the first embodiment of the present application, the embodiment provides a detachable knife switch mechanical locking device, which can realize the effect of replacing the knife switch locking hanging ring without power interruption and without the need to re-adjust the knife switch, and the operation difficulty is small, which comprises: a limiting component 100 with a notch and a connecting component 200 detachably connected to the notch.
[0038] Specifically, the limiting component 100 is the main body of the locking hanging ring, which is not limited to a circular ring, comprising a limiting groove 101 capable of accommodating the knife switch locking rod and the auxiliary fixing together, and at least one notch for the knife switch locking rod and the auxiliary fixing to pass through, and the rest of the limiting component 100 except the notch is continuous. The auxiliary fixing is fixed itself and close to the knife switch locking rod, in this embodiment, the auxiliary fixing is selected as the knife switch vertical main connecting rod which is parallel to the vertical knife switch locking rod and close to it, and the knife switch locking rod and the auxiliary fixing can pass through the notch and enter the limiting groove 101.
[0039] Further, the connecting component 200 is detachably installed at the notch of the limiting component 100. After the knife switch locking rod and the auxiliary fixing both pass through the notch and enter the limiting groove 101, the connecting component 200 is installed at the notch to block, when the connecting component 200 is installed at the notch, the limiting groove 101 can block the knife switch locking rod from being separated from the auxiliary fixing in the operating direction in all directions, thereby keeping the locking of the knife switch.
[0040] Preferably, the connecting component 200 comprises an adapter one 201 and an adapter two 202 which are separately arranged on the limiting component 100 at both sides of the notch, it is worth noting that the structure of the adapter one 201 and the adapter two 202 can be the same, and the naming of the adapter one 201 and the adapter two 202 here is only for the convenience of description, and it is not specifically limited to which side of the notch or structure, the adapter one 201 and the adapter two 202 are connected by a locking piece 203, and the locking piece 203 is used to fix the distance between the adapter one 201 and the adapter two 202. The main body of the locking hanging ring is a non-elastic structure, so that after the distance between the adapter one 201 and the adapter two 202 is fixed by the locking piece 203, the size of the limiting groove 101 remains fixed and no longer changes, thereby preventing the knife switch locking rod from being pressed to increase the limiting groove 101 and then being separated from the auxiliary fixing; or the elastic interval of the locking hanging ring is limited, so that after the distance between the adapter one 201 and the adapter two 202 is fixed by the locking piece 203, the limiting groove 101 can still block the knife switch locking rod from being separated from the auxiliary fixing and rotating to the unlocked state when the elastic deformation reaches the maximum range.
[0041] The first abutting piece 201 and the limiting assembly 100, or / and the second abutting piece 202 and the limiting assembly 100, or / and the locking piece 203 and the first abutting piece 201 and the second abutting piece 202 are detachably connected. The connecting assembly 200 is detachably installed at the gap of the limiting assembly 100. In order to facilitate replacement, any two of the first abutting piece 201, the second abutting piece 202 and the locking piece 203 are detachably connected. When replacement is needed, the detachable part is only needed to be detached, so that the knife shutter locking rod and the auxiliary fixing object can pass through the gap, and then the locking ring of the limiting assembly 100 is detached and removed, facilitating replacement.
[0042] Embodiment 2
[0043] Reference Figure 4 and Figure 5 The second embodiment of the present application is different from the previous embodiment. The second embodiment provides a limiting assembly 100 with not less than two gaps, which divides the limiting assembly 100 into at least two limiting parts 102, facilitating installation of the locking ring.
[0044] Specifically, the gap is provided with not less than two groups, the limiting assembly 100 is divided into a plurality of limiting parts 102 by the not less than two gaps, and the adjacent two limiting parts 102 are detachably connected by the connecting assembly 200 at the gap. The limiting groove 101 is formed between the limiting parts 102 connected by the connecting assembly 200. In the embodiment, the gap is provided with two groups, the limiting assembly 100 is divided into two limiting parts 102 by the two gaps, and the two limiting parts 102 are sequentially surrounded by the knife shutter locking rod and the auxiliary fixing object during installation, so that the knife shutter locking rod and the auxiliary fixing object are located in the limiting groove 101, and then the connecting assembly 200 at the gap is installed.
[0045] Further, the limiting part 102 includes a plurality of groups of strip segments 102a and arc segments 102b connected in sequence, at least one group of strip segments 102a is connected with the gap, and the first abutting piece 201 and the second abutting piece 202 are arranged on the strip segment 102a connected with the gap. Since the main body of the locking ring is mostly a circular annular shape formed by scanning along a certain track, in the embodiment, the strip segment 102a refers to the circular scanning track of the main body of the locking ring as a straight line, and the appearance shows a straight line segment. The arc segment 102b refers to the circular scanning track of the main body of the locking ring as a circular arc or an elliptical arc.
[0046] The radius of the arc-shaped section 102b is adapted to the shape of the knife gate locking rod or the auxiliary fixing. Since the knife gate locking rod and the auxiliary fixing in this embodiment are both approximately cylindrical, the radius of the two arc-shaped sections 102b on the two limiting portions 102 can be adapted to the radius of the knife gate locking rod and the auxiliary fixing, respectively. This not only saves material and space, but also makes the limiting groove 101 more suitable for the shape of the knife gate locking rod and the auxiliary fixing, so that the movable clearance of the knife gate locking rod in the limiting groove 101 is approximately the same in all directions, preventing the knife gate from being unlocked due to excessive rotation of the knife gate locking rod caused by a large clearance in a certain direction. The abutting piece one 201 and the abutting piece two 202 are arranged on the strip-shaped section 102a connected to the notch, and when the abutting piece one 201 and the abutting piece two 202 are fixed by the locking piece 203, the strip-shaped sections 102a on which the abutting piece one 201 and the abutting piece two 202 are arranged are parallel to each other, facilitating the abutting piece one 201 and the abutting piece two 202 to move closer to or farther away from each other along the strip-shaped section 102a during installation, disassembly or replacement, thereby quickly realizing the combination or separation of the two limiting portions 102.
[0047] The remaining structure is the same as that of Embodiment 1.
[0048] Embodiment 3
[0049] Referring to Figure 6 and Figure 7 This is the third embodiment of the present application, which is different from the previous embodiment in that it provides only one set of notches and one set of rotation centers 103. The limiting assembly 100 is divided into two sets of limiting portions 102 by the set of notches and the set of rotation centers 103, solving the problem of complicated installation caused by too many sets of notches and matching connecting assemblies 200.
[0050] Specifically, the notch is provided with one set, and the limiting assembly 100 further includes one set of rotation centers 103. The rotation centers 103 and the notches divide the limiting assembly 100 into two sets of limiting portions 102, and the two sets of limiting portions 102 are connected by rotation through the rotation centers 103. The two sets of limiting portions 102 are connected by rotation through the rotation centers 103, so that the size of the gap between the two sets of limiting portions 102 can be adjusted by rotation. After the gap is increased by rotation, the knife gate locking rod and the auxiliary fixing can enter the limiting groove 101. Then, the gap is reduced by rotation, and the distance between the abutting piece one 201 and the abutting piece two 202 on both sides of the gap is fixed by the locking piece 203, completing the limiting and locking of the knife gate locking rod.
[0051] Further, the rotation center 103 is a rotating shaft penetrating through the two sets of limiting parts 102, and the two sets of limiting parts 102 are each provided with a strip-shaped slot 102c in sliding connection with the rotating shaft. The two sets of limiting parts 102 are connected through the rotating shaft, and at least one of the two sets of limiting parts 102 is provided with a strip-shaped slot 102c in sliding connection with the rotating shaft, so that the rotating shaft can rotate and slide in the strip-shaped slot 102c at the same time. In this embodiment, the two sets of limiting parts 102 are each provided with a strip-shaped slot 102c, and the rotating shaft penetrates through the two strip-shaped slots 102c at the same time. The two ends of the rotating shaft are provided with limiting structures to prevent disengagement from the strip-shaped slots 102c. When the two sets of limiting parts 102 are rotated through the rotating shaft to the strip-shaped sections 102a where the butt joint part one 201 and the butt joint part two 202 are parallel to each other, the strip-shaped slots 102c of the two sets of limiting parts 102 are parallel in the same direction at this time. In this way, the size of the limiting slot 101 formed inside can be adjusted by approaching or moving away from the two sets of limiting parts 102 along the direction of the strip-shaped slots 102c, so as to improve the adaptability.
[0052] The limiting assembly 100 and the connecting assembly 200 that constitute the locking hanging ring are generally made of metal materials with sufficient strength. In outdoor environments, especially in some coastal cities, the surface of the locking hanging ring is prone to rust, which is not conducive to its effective use. In this embodiment, each component of the limiting assembly 100 and each component of the connecting assembly 200 are made of stainless steel or surface galvanized materials to enhance the service life. The connection between the limiting assembly 100 and the connecting assembly 200 is more prone to rust due to the difficulty of rust-proof processing and wear caused by installation and disassembly. Therefore, the fewer the notches, the less the impact on the overall service life, and at the same time, the installation steps can be simplified, which can be popularized.
[0053] The remaining structure is the same as that of Embodiment 2.
[0054] Embodiment 4
[0055] Reference Figures 8-10 This is the fourth embodiment of the present application, which is different from the previous embodiment. This embodiment provides a preferred implementation structure of the connecting assembly 200.
[0056] Specifically, the first connecting piece 201 and the second connecting piece 202 are external threads arranged on the surface of the strip-shaped section 102a and in the same direction. The same direction here means that the external threads on the surfaces of the first connecting piece 201 and the second connecting piece 202 are in the same rotation direction when the first connecting piece 201 and the second connecting piece 202 are installed by the locking piece 203. In addition, the external threads of the first connecting piece 201 and the second connecting piece 202 are the same in other dimensions. The locking piece 203 includes a connecting sleeve 203a provided with internal threads. Therefore, when the first connecting piece 201 and the second connecting piece 202 are coaxially installed, the connecting sleeve 203a can simultaneously threadedly slide between the external threads of the first connecting piece 201 and the second connecting piece 202 through the internal threads, thereby fixing the distance between the first connecting piece 201 and the second connecting piece 202 through thread cooperation.
[0057] Further, the locking piece 203 further includes a limiting nut 203b arranged on the surface of the external thread. In the embodiment, the limiting nut 203b is provided with two groups, and the two groups of limiting nuts 203b are respectively threadedly slid on the external threads on the surfaces of the first connecting piece 201 and the second connecting piece 202. When the distance between the first connecting piece 201 and the second connecting piece 202 is fixed by the connecting sleeve 203a, the limiting nuts 203b on both sides are screwed to press the connecting sleeve 203a, thereby limiting the connecting sleeve 203a, preventing it from being threadedly slid by mistake, and delaying the loosening of the connecting sleeve 203a after long-term use. In order to facilitate installation and replacement, the outer surface of the connecting sleeve 203a in the embodiment is provided with a hexagonal cross section which is the same as the limiting nut 203b, thereby facilitating the operator to uniformly operate by using the same type of wrench.
[0058] The remaining structure is the same as that of the embodiment 3.
[0059] Use method:
[0060] When the gap of the limiting assembly 100 is not less than two groups: first, the adjacent two limiting parts 102 are surrounded by the limiting groove 101 and the auxiliary fixing object, and then the gap between the two groups of limiting parts 102 is installed and connected by the connecting assembly 200, and then the remaining groups of limiting parts 102 are sequentially connected between the current two groups of limiting parts 102 by the connecting assembly 200, until the knife shutter locking rod and the auxiliary fixing object are completely surrounded and fixed.
[0061] The installation and connection method of the connecting assembly 200 is as follows: first, the two limiting nuts 203b are respectively screwed and installed on the external threads of the abutting piece one 201 and the abutting piece two 202 on both sides of the gap, and the limiting nuts 203b are rotated as far away from the gap as possible, then the connecting sleeve 203a is screwed on the external thread of the abutting piece one 201, and the internal thread of the connecting sleeve 203a is connected with the external thread of the abutting piece one 201 as much as possible, and the connecting sleeve 203a can be selected to be screwed to connect all the internal threads with the external thread of the abutting piece one 201, then the abutting piece one 201 and the abutting piece two 202 on the strip-shaped section 102a are aligned, so that the centers of the external threads of the abutting piece one 201 and the abutting piece two 202 are coaxial, and the distance between the abutting piece one 201 and the abutting piece two 202 is maintained according to the need, then the connecting sleeve 203a is screwed in the opposite direction, so that the internal thread of the connecting sleeve 203a gradually draws the external thread of the abutting piece one 201, then the internal thread of the connecting sleeve 203a cooperates with the external thread of the abutting piece two 202 to screw and slide, when the internal thread of the connecting sleeve 203a is connected with the external threads of the abutting piece one 201 and the abutting piece two 202, the distance between the abutting piece one 201 and the abutting piece two 202 is fixed, at this time, the connecting sleeve 203a is rotated, so that the internal thread of the connecting sleeve 203a is close to the connection part of the external threads of the abutting piece one 201 and the abutting piece two 202, in order to balance the stress on both sides, then the limiting nuts 203b on the abutting piece one 201 and the abutting piece two 202 are screwed and slid to press the connecting sleeve 203a, so as to fix the connecting sleeve 203a;
[0062] When the knife switch needs to be operated or the knife switch mechanical locking device needs to be replaced, the limiting nut 203b of any abutting piece one 201 on one side of the gap can be screwed to the side away from the connecting sleeve 203a, and then the connecting sleeve 203a is screwed and slid to the same side, so that the internal thread of the connecting sleeve 203a is separated from the external thread of the abutting piece two 202 on the other side, and then the abutting piece one 201 and the abutting piece two 202 on both sides of the gap are disassembled and separated, and the same method is used to disassemble and separate the abutting piece one 201 and the abutting piece two 202 on both sides of the remaining gaps, and the disassembly is completed. The installation process after the operation of the knife switch or the use of the new knife switch mechanical locking device has been described above, and will not be repeated here, so that the replacement process without power failure can be completed.
[0063] When the gap of the limiting assembly 100 is set as a group: first, rotate the two groups of limiting parts 102 through the rotating shaft of the rotating center 103, so that the gap between the two groups of limiting parts 102 can be adjusted by rotating, and after the gap is increased by rotating, the knife shutter locking rod and the auxiliary fixing pass into the limiting slot 101, then the gap is reduced by rotating, until the bar-shaped section 102a where the abutting piece one 201 and the abutting piece two 202 are located is aligned, so that the outer thread centers of the abutting piece one 201 and the abutting piece two 202 are coaxial, at this time, the bar-shaped slots 102c of the two groups of limiting parts 102 are also parallel in the same direction, the size of the limiting slot 101 formed can be adjusted by moving the two groups of limiting parts 102 closer or farther along the direction of the bar-shaped slot 102c, and then the distance between the abutting piece one 201 and the abutting piece two 202 on both sides of the gap is fixed by the locking piece 203, the limiting and locking of the knife shutter locking rod are completed. The mounting and dismounting process of the locking piece 203 and the abutting piece one 201 and the abutting piece two 202 is consistent with the above process, which will not be described here.
