[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1, reference Figure 1 - Figure 3 , which is the first embodiment of the present invention, provides a hand-operated isolating switch operator, the device comprising: an operating unit 100 including an operating handle 101, an auxiliary component 102 arranged on the outer diameter of the operating handle 101, and the entire device can be operated and adjusted through the operating handle 101;

[0032] The limiting unit 200 includes a limiting component 201 disposed at one end of the auxiliary component 102. The knife switch body 401 can be quickly fixed by the cooperation between the auxiliary component 102 and the limiting component 201.

[0033] The fixing unit 300 includes a supporting assembly 301 disposed on the auxiliary assembly 102, and a fixing assembly 302 disposed on the supporting assembly 301. The knife switch body 401 can be engaged by the cooperation of the supporting assembly 301 and the fixing assembly 302 to complete the preliminary installation, and the fixing assembly 302 can complete the fixed installation; and,

[0034] The grounding knife switch unit 400 includes a knife switch body 401 disposed at one end of the fixing component 302 , and the knife switch body 401 can be fixed by the fixing component 302 .

[0035] Among them, the auxiliary component 102 includes an anti-slip cover 102a arranged on the outer diameter of the operating handle 101, a base 102b arranged at the other end of 101a, and a fixing ring 102c arranged at one end of the anti-slip cover 102a, and the fixing ring 102c is connected to the operating handle 101. The auxiliary component 102 on the outer diameter of the operating handle 101 can make the use of the operating handle 101 more convenient and quicker.

[0036] During use, when the knife gate body 401 is repaired or adjusted, the operator inserts the support assembly 301 and the fixing assembly 302 inside the limit assembly 201 into the knife gate body 401, so that the operating unit 100 is initially fixed on the knife gate body 401 as a whole, and pre-installed and initially fixed at the same time, by holding the auxiliary assembly 102, the other hand rotates the limit assembly 201, so that the limit assembly 201 rotates and moves along the support assembly 301, and while the limit assembly 201 rotates and moves, the fixing assembly 302 inside the limit assembly 201 is squeezed, so that the fixing assembly 302 shrinks, Until the fixing component 302 is completely stuck in the outer diameter of the knife switch body 401, the fixing of the knife switch body 401 is completed. After the fixing is completed, the grounding knife switch unit 400 is disassembled, repaired and adjusted through the operating unit 100, and the fixing component 302 is squeezed by the limit component 201, so that the fixing component 302 can adapt to a variety of different specifications of knife switch bodies 401, and the knife switch body 401 can be quickly fixed and disassembled, and the operating tube and the operating handle of the isolating switch itself are not matched, and the employees do not have a comprehensive grasp of the operating method, etc., which often cause safety incidents such as people falling during operation and the operating tube slipping and injuring people.

[0037] Through innovative component designs, such as the limit component 201, the support component 301 and the fixing component 302, the knife switch body 401 can be fixed and disassembled quickly and stably, which significantly improves the efficiency of maintenance and adjustment work. Its wide adaptability ensures compatibility with knife switch bodies 401 of different specifications, while enhancing the safety of operation and reducing safety accidents such as slippage of the operating pipe and falls of personnel. The simplified operating process and integrated design reduce labor intensity and maintenance costs, while improving the quality of maintenance. In addition, the durability and environmental adaptability of the operator enable it to maintain high performance under various working conditions, promote standardized operating procedures, and promote the modernization and efficiency of power system maintenance work.

[0038] Example 2, reference Figure 1 - Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the limiting assembly 201 includes a rotating clamping ring 201b arranged on one end of the operating handle 101, the rotating clamping ring 201b is threadedly connected to the operating handle 101, and a limiting sleeve 201a is arranged on the rotating clamping ring 201b, and the limiting sleeve 201a cooperates with the supporting assembly 301, and the overall fixation of the knife gate body 401 is completed by rotating the limiting assembly 201.

[0039] Compared with Example 1, further, a sliding groove 201c is provided inside the limiting sleeve 201a. By rotating the limiting component 201, the limiting component 201 starts to move and starts to squeeze the sliding groove 201c on the limiting sleeve 201a, so that the sliding groove 201c is squeezed toward the fixing component 302, thereby completing the fixation of the knife gate body 401.

[0040] During use, when the knife gate body 401 is pre-installed and fixed, the operating handle 101 is held at one end, and the limiting sleeve 201a is inserted into the knife gate body 401 at the other end for pre-installation, and then the rotating clamp ring 201b is rotated to make the rotating clamp ring 201b start to rotate and move along the thread 301b, so that the limiting clamp ring 201a starts to move with the sliding groove 201c, and the movement of the sliding groove 201c makes the internal fixing component 302 begin to be squeezed, so that the fixing component 302 begins to deform, and the rotating clamp ring 201b is rotated to finally fix the fixing component 302 on the knife gate body 401 to complete the installation. During disassembly, it is only necessary to rotate the rotating clamp 201b in the opposite direction, so that the rotating clamp 201b and the limiting sleeve 201a move in the opposite direction with the sliding groove 201c, and the fixing component 302 can be separated to complete the quick disassembly. By rotating the limiting component 201, the limiting component 201 and the fixing component 302 can be matched, so that the knife gate body 401 can be quickly installed and the knife gate body 401 can be quickly disassembled, making it easy to operate and use. While improving operating comfort and work efficiency, it also reduces maintenance costs and training requirements. Its ergonomic design reduces the physical fatigue of the operator, and its corrosion-resistant properties ensure reliability in harsh environments.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3, reference Figure 1 - Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the supporting assembly 301 includes a low ring 301a arranged at one end of the operating handle 101, a thread 301b arranged on the outer diameter of the low ring 301a, and a fixed base 301c arranged at the other end of the low ring 301a. The fixing assembly 302 is supported and fixed as a whole by the low ring 301a and the fixed base 301c fixed at one end of the operating handle 101.

[0043] Compared with Example 2, further, the fixed component 302 includes a buffer conical block 302a arranged on the fixed base 301c, and a movable ring 302b arranged at one end of the buffer conical block 302a, and the movable ring 302b cooperates with the sliding groove 201c. Through the cooperation between the buffer conical block 302a and the movable ring 302b on the fixed base 301c and the limiting component 201, the knife gate body 401 can be fixed.

[0044] Furthermore, a fixed ring plate 302c is provided at one end of the movable ring 1 302b, and a movable ring 2 302d is provided at one end of the fixed ring plate 302c, and the movable ring 2 302d is slidably connected to the inside of the limiting sleeve 201a. Through the cooperation between the fixed ring plate 302c and the movable ring 2 302d and the limiting sleeve 201a, the limiting sleeve 201a can be moved to be fixed.

[0045] Furthermore, a fixed conical block 302e is provided at one end of the movable ring 2 302d, and the fixed conical block 302e cooperates with the knife gate body 401, and the knife gate body 401 is fixed by the fixed conical block 302e.

[0046] Furthermore, the outer diameter of the buffer conical block 302a is provided with a buffer groove 302a-1, and the outer diameter of the fixed conical block 302e is provided with a deformation groove 302e-1. Through the cooperation of the buffer groove 302a-1 and the deformation groove 302e-1, the fixed conical block 302e is buffered and limited when it is squeezed by the limiting sleeve 201a.

[0047] During use, when fixing different knife gate bodies 401, the operating handle 101 is held at one end, and the limiting sleeve 201a is inserted into the knife gate body 401 at the other end for pre-installation. By fixing the expanded caliber size of the tapered block 302e, knife gate bodies 401 of different specifications can be inserted for pre-installation and stuck on the outer diameter of the knife gate body 401. By rotating the limiting assembly 201, the limiting assembly 201 squeezes the moving ring 1 302b, causing the moving ring 1 302b to start to shrink, and at the same time, the moving ring 2 302d also starts to shrink, causing the fixed tapered block 302e to start to deform and shrink, and the knife gate body 401 is gradually fixed, and the fixed tapered block 30 2e internal fixing ring plate 302c is also inserted into the interior of the fixing assembly 302, and the knife gate body 401 is fixed for a second time, so that the fixation is more stable, and when the fixed conical block 302e starts to shrink to fix the knife gate body 401, the deformation of the fixed conical block 302e is buffered and adjusted by the deformation groove 302e-1 set on the surface of the fixed conical block 302e, and the deformation of the buffering conical block 302a is coordinated by the fixed conical block 302e, so that the fixed conical block 302e can be gradually fixed on the surface of the knife gate body 401, and the knife gate body 401 is adjusted by the operator controlling the operating handle 101 to prevent safety incidents such as people falling during operation, operating pipe slipping and injuring people, etc.

[0048] And through its innovative multi-specification adaptable design, it achieves fast and stable fixation of different knife switch bodies 401. Its progressive fixing mechanism and double fixing guarantees ensure the accuracy of the fixing process and the stability of the structure. The buffer adjustment design effectively protects the knife switch body 401 and extends the service life of the operator. The simplified operating procedures and improved safety performance reduce operating risks and improve maintenance efficiency. In addition, the cost-effectiveness, environmental adaptability and promotion of standardized operations of the operator have significantly improved the modernization level of power system maintenance and comprehensively promoted technological progress and efficiency improvement in the industry.
