DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the drawings of the specification.

[0026] In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Secondly, as used herein, an "embodiment" or "embodiments" refers to specific features, structures, or characteristics that may be included in at least one implementation of the present invention. The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments.

[0028] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure are enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0029] Embodiment 1

[0030] Referring to Figure 1 , for the first embodiment of the present invention, a special mechanical anti-misoperation device for portable GIS knife-switch maintenance is provided. This device includes a GIS device; an electromagnetic device 100 located on one side of the GIS device. The electromagnetic device 100 includes an electromagnetic fixing component 101, a central shaft 102, a clamping mechanism 103, and a pull rod assembly 104. The central shaft 102 is installed on one side of the electromagnetic fixing component 101, the clamping mechanism 103 is installed on one side of the central shaft 102, and the pull rod assembly 104 is installed on one side of the clamping mechanism 103.

[0031] Specifically, the electromagnetic fixing component 101 includes a button 101a. By controlling the electromagnetic fixing component 101 with the button 101a, the electromagnetic fixing component 101 can be stably adsorbed on the metal shell of the GIS device.

[0032] Further, a T-shaped hole 102a is formed in the central shaft 102, and a bolt 102c is slidably connected inside the T-shaped hole 102a.

[0033] Among them, the electromagnetic fixing component 101 is located on one side of the GIS device. It includes an electromagnetic device 100, and a control button 101a is installed on the electromagnetic device 100. By pressing the button 101a, the electromagnet inside the electromagnetic device 100 can be activated to generate magnetism and firmly adsorb on the metal shell of the GIS device. This design not only ensures the stability of the anti-misoperation device but also allows users to quickly install or disassemble the device, greatly improving work efficiency.

[0034] Next is the central axis 102 part, which connects the electromagnetic fixing component 101 and the clamping mechanism 103, and a T-shaped hole 102a is provided on the central axis 102. A bolt 102c is slidably connected in this T-shaped hole 102a. The bolt 102c is fixed on the GIS device. The bolt 102c is inserted from one side of the T-shaped hole 102a. After adjusting to an appropriate length, the bolt 102c is tightened to fix the position of the bolt 102c and the central axis 102. This enables the central axis 102 to adjust its angle and length according to the actual use environment to adapt to GIS disconnector devices of different models and sizes. This adjustable design increases the flexibility of the device, ensuring that it can be widely applied to various GIS devices.

[0035] The clamping mechanism 103 is installed at one end of the central axis 102, and the pull rod assembly 104 is connected to the clamping mechanism 103. The clamping mechanism 103 mainly consists of two hoop clamps 104a, which are respectively located on the upper and lower sides and surround the output shaft or toggle arm of the GIS disconnector. When it is necessary to lock the disconnector, the motor in the pull rod assembly 104 is started. The motor will drive the pull rod to act, causing the hoop clamps 104a to close and tightly hold the transmission connecting rod 104b or toggle arm of the GIS disconnector, thereby preventing any external force (such as misoperation) from driving the disconnector to act. Such a design effectively avoids the safety hazards caused by misoperation and at the same time ensures the safety and reliability of the primary part of the disconnector.

[0036] In summary, the components of this device are closely coordinated: the electromagnetic fixing component 101 provides a stable foundation, the central axis 102 realizes flexible adjustment of position and angle, and the clamping mechanism 103 combined with the pull rod assembly 104 completes the locking function of the GIS disconnector. The entire system is designed compactly, easy to operate, and optimized to meet the needs of on-site work, providing a strong guarantee for the safe operation of the power system.

[0037] Embodiment 2

[0038] Refer to Figures 1 to 5 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the clamping mechanism 103 includes a clamping motor 103a. The clamping motor 103a is fixedly connected to one end of the central axis 102, and a support rod 103b is fixedly connected to the central axis 102. The support rod 103b is located on one side of the clamping motor 103a.

[0039] Furthermore, both ends of the support rod 103b are fixedly connected with telescopic rods 103c. One end of the telescopic rod 103c is equipped with an electric wire. One end of the central axis 102 close to the telescopic rod 103c is fixedly connected with a first clamping block 103d. A first through groove is opened on the first clamping block 103d. One end of the telescopic rod 103c is fixedly connected with a second clamping block 103f

[0040] Further, a second through groove 103g is formed in the second clamping block 103f. The second through groove 103g and the first through groove are corrugated. When the first clamping block 103d and the second clamping block 103f are combined, the first through groove and the second through groove 103g form a circular accommodating groove.

[0041] Specifically, the pull rod assembly 104 includes a hoop 104a. One side of the first clamping block 103d is fixedly connected to the hoop 104a. The hoop 104a is divided into upper and lower parts, and the hoop 104a is provided with a through hole. The pull rod assembly 104 further includes a transmission connecting rod 104b. The through hole of the hoop 104a is used to clamp and fix the transmission connecting rod 104b.

[0042] During use, the core of the movement of the clamping mechanism 103 is the clamping motor 103a, which is fixedly connected to one end of the central shaft 102. The support rod 103b is located on one side of the clamping motor 103a, and telescopic rods 103c are fixedly connected to both ends, and the support rod 103b provides additional support. These telescopic rods 103c not only provide the necessary structural support for the clamping mechanism 103, but also have a certain degree of flexibility to adapt to GIS disconnectors of different sizes and types. One end of the telescopic rod 103c is equipped with an electric wire for transmitting electric power to the clamping motor 103a to ensure its normal operation.

[0043] At one end of the central shaft 102 close to the telescopic rod 103c, a first clamping block 103d is fixedly connected. A first through groove is formed in the clamping block, and the other end of the telescopic rod 103c is fixedly connected to a second clamping block 103f, on which a second through groove 103g is formed. These two through grooves are designed to be corrugated. When the first clamping block 103d and the second clamping block 103f are combined, they jointly form a circular accommodating groove, which can tightly wrap the output shaft or toggle arm of the GIS disconnector, that is, the transmission connecting rod 104b, so as to effectively lock the disconnector. This corrugated design improves the clamping force and ensures the firmness and reliability of the lock.

[0044] The pull rod assembly 104 is an important part of the clamping mechanism 103, and it includes a hoop 104a and a transmission connecting rod 104b. The hoop 104a is divided into upper and lower parts, and each part is provided with a through hole for clamping and fixing the transmission connecting rod 104b of the GIS disconnector. When the clamping motor 103a is started, it drives the hoop 104a to close through the transmission connecting rod 104b, so that the first clamping block 103d and the second clamping block 103f are closely attached, and then the output shaft or toggle arm of the GIS disconnector is locked. This process ensures that even if there is a misoperation, the disconnector cannot move, greatly reducing the safety risk.

[0045] The transmission connecting rod 104b is composed of three groups of rods. When the first rod rotates away from the first clamping block 103d and the second clamping block 103f, it pulls the second rod in the middle to move, and then pulls the rotation of the third rod close to the first clamping block 103d and the second clamping block 103f. One end of the third rod close to the first clamping block 103d is limited. Therefore, one end of the third rod connected to the second rod rotates around the end of the third rod close to the first clamping block 103d. At this time, it is in the open circuit state.

[0046] The usage method is as follows: First, adsorb the electromagnetic fixing component 101 onto the metal shell of the GIS device, and then adjust the angle and length of the central axis 102 to make it suitable for a specific GIS disconnecting switch device. Next, start the clamping motor 103a, and through the control circuit, make the telescopic rod 103c drive the second clamping block 103f to move towards the first clamping block 103d until the two are completely closed and form a circular accommodating groove, tightly wrapping the transmission connecting rod 104b of the GIS disconnecting switch. After completing the above steps, the portable mechanical anti-maloperation device for GIS disconnecting switch maintenance is in the closed circuit state, effectively preventing the misoperation of the disconnecting switch and protecting the safety of personnel and equipment.

[0047] In summary, the clamping mechanism 103 and its various components form a highly cooperative system. From the stable electromagnetic fixing foundation to the flexible adjustment of the central axis 102, and then to the precise clamping and locking mechanism, each part plays an indispensable role in ensuring the safety of the GIS disconnecting switch.

[0048] Embodiment 3

[0049] Refer to Figures 1 to 5 , which is the third embodiment of the present invention.

[0050] The operation process of this device: First, the electromagnetic fixing component 101 needs to be adsorbed onto the metal shell of the GIS device to ensure its stability. Then, adjust the angle and length of the device by adjusting the T-shaped hole 102a and the sliding bolt 102c on the central axis 102 to make it suitable for GIS disconnecting switch devices of different models and sizes. Subsequently, start the clamping motor 103a, which will drive the telescopic rod 103c to act, making the second clamping block 103f move towards the first clamping block 103d. When the two are combined, a circular accommodating groove is formed, tightly wrapping the transmission connecting rod 104b of the GIS disconnecting switch. After completing the above steps, the device enters the closed circuit state, effectively preventing the mis-opening and mis-closing of the disconnecting switch.

[0051] When the disconnecting switch needs to be placed in the open state, rotate the first rod away from the first clamping block 103d and the second clamping block 103f, pull the second rod in the middle to move, and then pull the rotation of the third rod close to the first clamping block 103d and the second clamping block 103f. Since one end of the third rod close to the first clamping block 103d is limited, one end of the third rod connected to the second rod rotates around the end of the third rod close to the first clamping block 103d. This design ensures that even if an external force attempts to change the state of the disconnecting switch, the transmission link 104b cannot complete the action, thus avoiding the misoperation of the disconnecting switch.

[0052] It is important to note that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible without substantially departing from the novel teachings and advantages of the subject matter described in this application (for example, the dimensions, scales, structures, shapes and proportions of various elements, and parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, color, orientation changes, etc.).
