Description

Technical Field

[0001] This utility model relates to the field of electric grounding switch technology, and in particular to an electric grounding switch with manual operation function. Background Technology

[0002] Electric grounding switches are safety devices used in power systems. They are mainly used to ensure reliable grounding of circuit parts during equipment maintenance or repair, thereby protecting the safety of personnel.

[0003] Chinese Patent Publication No. CN219759394U, published on 20230926, discloses a high-voltage electric grounding switch, including a fixed base plate, a mounting plate at the top of the fixed base plate, a conductive component at the top of the mounting plate, and a control component on the side of the top of the fixed base plate near the mounting plate. The control component is used to control the opening and closing of the grounding switch. A docking component is provided at the bottom of the conductive component, and the docking component is used to connect the control component and the conductive component.

[0004] Existing electric grounding switches, such as those mentioned above, mostly rely on a drive mechanism to rotate a drive rod. The drive rod, through a rotating frame, causes the connecting guide plate to flip, thereby enabling the connection and separation of the connecting guide plate and the insulator. In practice, if the drive mechanism malfunctions, the entire rotating frame and the connecting guide plate will be completely locked, making it impossible for the operator to disconnect the connecting guide plate. This increases the limitations of the electric grounding switch. Therefore, there is an urgent need to propose an electric grounding switch with manual operation function to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an electric grounding switch with manual operation function in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electric grounding switch with manual operation function includes a support base and a flip frame. An insulator and a connecting guide plate are fixedly connected to the outer walls of the support base and the flip frame, respectively. A bracket is fixedly connected to the outer wall of the support base. A rotating rod is rotatably connected to the inner wall of the bracket. The outer wall of the rotating rod is fixedly connected to the flip frame. A rotating component is detachably connected to the outer wall of the bracket. The output end of the rotating component is connected to the rotating rod through a connecting assembly.

[0008] Preferably, the bracket is fixedly connected to the support base via a locking rod.

[0009] Preferably, the connecting assembly includes a fixed sleeve and an extension rod II, the fixed sleeve and the extension rod II being fixedly connected to the output end of the rotating component and the rotating rod, respectively, and the outer wall of the fixed sleeve is provided with a locking part for locking the position of the extension rod II.

[0010] Preferably, the locking part includes a positioning rod that is screwed into the outer wall of the fixed sleeve, and the positioning rod is screwed into the inner wall of the extension rod II through a screw hole.

[0011] Preferably, a mounting bracket is fixedly connected to the bottom of the rotating component, and the vertical end of the mounting bracket is fixedly connected to the outer wall of the support by screws.

[0012] Preferably, an outer extension rod is fixedly connected to the side of the rotating rod away from the outer extension rod two, and a convex ring is fixedly connected to the outer wall of the outer extension rod one.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, under normal operating conditions, the output end of the rotating component rotates in conjunction with the outer extension rod two via the fixed sleeve. The rotating rod drives the connecting guide plate to rotate via the flipping frame, thereby realizing the automatic opening and closing between the connecting guide plate and the insulator. When the rotating component malfunctions, the rotating positioning rod is rotated to separate the outer extension rod two from the fixed sleeve. At this time, the rotating rod loses the constraint force from the fixed sleeve. The operator can use tools to cooperate with the convex ring on the outer extension rod one to drive the outer extension rod one and the rotating rod to rotate, which can also realize the separation of the connecting guide plate and the insulator. The electric grounding switch also has a manual function, thereby improving the applicability of the electric grounding switch.

[0015] 2. In this application, after the bracket is connected to the outer wall of the support base by a step, the bracket and the support base are fixed by a locking rod. This ensures the stability of the bracket position and improves the convenience of subsequent disassembly and assembly of the bracket, so as to facilitate the subsequent disassembly and maintenance of the connecting guide plate and its related drive components, thereby improving the convenience of using the electric grounding switch.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] An electric grounding switch with manual operation function includes a support base 1 and a flip frame 3. An insulator 2 and a connecting guide plate 4 are fixedly connected to the outer walls of the support base 1 and the flip frame 3, respectively. A bracket 5 is fixedly connected to the outer wall of the support base 1. A rotating rod is rotatably connected to the inner wall of the bracket 5. The outer wall of the rotating rod is fixedly connected to the flip frame 3. A rotating component 9 is detachably connected to the outer wall of the bracket 5. The output end of the rotating component 9 is connected to the rotating rod through a connecting assembly.

[0025] Under normal operating conditions, the output end of the rotating component 9 rotates in conjunction with the outer extension rod 12 via the fixed sleeve 11. The rotating rod drives the connecting guide plate 4 to rotate via the flipping frame 3, thereby realizing the automatic opening and closing between the connecting guide plate 4 and the insulator 2. When the rotating component 9 malfunctions, the rotating positioning rod 13 is rotated to separate the outer extension rod 12 from the fixed sleeve 11. At this time, the rotating rod loses the constraint force from the fixed sleeve 11. The operator can use tools to cooperate with the protruding ring 7 on the outer extension rod 6 to drive the outer extension rod 6 and the rotating rod to rotate, which can also realize the separation of the connecting guide plate 4 and the insulator 2. The electric grounding switch also has a manual function, thereby improving the applicability of the electric grounding switch.

[0026] Specifically, such as Figure 2 and Figure 4As shown, the bracket 5 is fixedly connected to the support base 1 by the locking rod 8. After the bracket 5 overlaps the outer wall of the support base 1 by the step, the bracket 5 is fixed to the support base 1 by the locking rod 8. This ensures the stability of the position of the bracket 5 and improves the convenience of subsequent disassembly and assembly of the bracket 5, so as to facilitate the subsequent disassembly and maintenance of the connecting guide plate 4 and its related drive components, thereby improving the convenience of using the electric grounding switch.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the connecting assembly includes a fixed sleeve 11 and an extension rod 12. The fixed sleeve 11 and the extension rod 12 are fixedly connected to the output end of the rotating component 9 and the rotating rod, respectively. The outer wall of the fixed sleeve 11 is provided with a locking part for locking the position of the extension rod 12. The locking part includes a positioning rod 13 that is screwed into the outer wall of the fixed sleeve 11. The positioning rod 13 is screwed into the inner wall of the extension rod 12 through a screw hole 14. Under normal operating conditions, the output end of the rotating component 9 rotates the rod in conjunction with the extension rod 12 through the fixed sleeve 11. When the rotating part 9 malfunctions, the rotating positioning rod 13 separates the outer extension rod 12 from the fixed sleeve 11. At this time, the rotating rod loses the constraint force from the fixed sleeve 11. The bottom of the rotating part 9 is fixedly connected to the mounting bracket 10. The vertical end of the mounting bracket 10 is fixedly connected to the outer wall of the bracket 5 by screws, thus ensuring the ease of disassembly and assembly of the rotating part 9. The side of the rotating rod away from the outer extension rod 12 is fixedly connected to the outer extension rod 6. The outer wall of the outer extension rod 6 is fixedly connected to the protruding ring 7 to facilitate manual driving of the rotating part 9.

[0028] Working principle: Under normal operating conditions, the output end of the rotating component 9 rotates in conjunction with the outer extension rod 12 via the fixed sleeve 11. The rotating rod drives the connecting guide plate 4 to rotate via the flipping frame 3, thereby realizing the automatic opening and closing between the connecting guide plate 4 and the insulator 2. When the rotating component 9 malfunctions, the rotating positioning rod 13 is rotated to separate the outer extension rod 12 from the fixed sleeve 11. At this time, the rotating rod loses the constraint force from the fixed sleeve 11. The operator can use tools to cooperate with the protruding ring 7 on the outer extension rod 6 to drive the outer extension rod 6 and the rotating rod to rotate, which can also realize the separation of the connecting guide plate 4 and the insulator 2. The electric grounding switch also has a manual function, thereby improving the applicability of the electric grounding switch. After the bracket 5 is connected to the outer wall of the support base 1 by the step, the bracket 5 and the support base 1 are fixed by the locking rod 8. This ensures the stability of the bracket 5 and improves the convenience of subsequent disassembly and assembly of the bracket 5, so as to facilitate the subsequent disassembly and maintenance of the connecting guide plate 4 and its related drive components, thereby improving the convenience of using the electric grounding switch.
