Description

Technical Field

[0001] This utility model relates to the technical field of manual operating mechanisms for high-voltage disconnect switches, specifically a manual operating mechanism for a high-voltage disconnect switch with a self-locking function. Background Technology

[0002] The manual operating mechanism of a high-voltage disconnector is a mechanism that enables the opening and closing of the disconnector through manual operation. The manual operating mechanism is suitable for high-voltage disconnectors of various voltage levels, especially in situations where there is no power supply or manual operation is required. Its advantages include simple structure, convenient maintenance, and no need for external power supply.

[0003] Most existing manual operating mechanisms for high-voltage disconnect switches lack self-locking protection. After operation, operators need to manually confirm and take additional measures to ensure the disconnect switch is in a stable open or closed state, making the operation cumbersome and inconvenient. Therefore, we propose a manual operating mechanism for high-voltage disconnect switches with self-locking function. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-voltage disconnector manual operating mechanism with a self-locking function. This solves the problem that most high-voltage disconnector manual operating mechanisms lack self-locking protection, requiring operators to manually confirm and take additional measures to ensure the disconnector is in a stable open or closed state after operation, resulting in cumbersome operating procedures.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A manual operating mechanism for a high-voltage disconnect switch with a self-locking function includes a high-voltage disconnect switch body.

A slider is slidably connected inside the connecting seat, and locking blocks are symmetrically fixedly connected to one side of the slider. The locking blocks are slidably connected to the connecting seat. Locking grooves that cooperate with the locking blocks are equidistantly opened inside the fixed seat. By moving the locking blocks into the locking grooves, the position of the connecting seat can be locked to prevent the disconnect switch from malfunctioning.

[0007] Preferably, a limiting rod is fixedly connected to the inner wall of the connecting seat, the slider is slidably connected to the limiting rod, and the slider is in contact with the inner wall of the connecting seat. The limiting rod can limit the movement of the slider and prevent the slider from deviating during movement.

[0008] Preferably, a return spring is provided between the slider and the connecting seat. One end of the return spring is fixedly connected to the slider, and the other end of the return spring is fixedly connected to the inner wall of the connecting seat. The return spring can drive the slider to move and reset.

[0009] Preferably, a push rod is fixedly connected to one side of the slider at equal intervals. The push rod is slidably connected to the connecting seat. A push block is fixedly connected to the end of the push rod away from the slider. Anti-slip protrusions are fixedly connected to one side of the push block at equal intervals. The push block drives the push rod to move, and the push rod drives the slider to move.

[0010] Preferably, the connecting rod is made of insulating material, which enhances the safety of the device.

[0011] Preferably, mounting blocks are symmetrically fixedly connected to the outer side of the fixed base, and the mounting blocks facilitate the installation and fixing of the fixed base with bolts.

[0012] This utility model provides a manual operating mechanism for a high-voltage disconnector switch with a self-locking function. Compared with the prior art, it has the following advantages: This manual operating mechanism for a high-voltage disconnector switch with a self-locking function realizes the function of manually opening and closing the switch by setting a connecting seat, sliding seat, connecting rod, push block, push rod, slider, return spring, locking block and locking groove.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution:

[0021] A manual operating mechanism for a high-voltage disconnect switch with a self-locking function includes a high-voltage disconnect switch body 1. A knife switch 4 is rotatably connected to the top of the high-voltage disconnect switch body 1. A connecting rod 5 is rotatably connected to one side of the knife switch 4. A fixed seat 3 is provided on one side of the high-voltage disconnect switch body 1. A connecting seat 6 is slidably connected to the inner wall of the fixed seat 3. A sliding seat 2 is fixedly connected to the top of the connecting seat 6. The sliding seat 2 is slidably connected to the fixed seat 3. The connecting rod 5 is rotatably connected to the sliding seat 2. A slider 9 is slidably connected inside the connecting seat 6. A locking block 11 is symmetrically fixedly connected to one side of the slider 9 for locking. Block 11 is slidably connected to connecting seat 6. The interior of fixed seat 3 is provided with locking grooves 10 that cooperate with locking block 11. The movement of sliding seat 2 drives connecting rod 5 to rotate, which in turn drives the switch 4 to rotate, facilitating the opening and closing of the switch. The movement of slider 9 drives locking block 11 to move into the corresponding locking groove 10, thereby locking the position of connecting seat 6. This can effectively prevent the disconnecting switch from malfunctioning due to vibration or other factors, and greatly improve the safety and stability of equipment operation.

[0022] Furthermore, a limiting rod 15 is fixedly connected to the inner wall of the connecting seat 6, and the slider 9 is slidably connected to the limiting rod 15. The slider 9 fits against the inner wall of the connecting seat 6. The movement of the slider 9 can be limited by the setting of the limiting rod 15 to prevent the slider 9 from deviating when moving.

[0023] Furthermore, a reset spring 14 is provided between the slider 9 and the connecting seat 6. One end of the reset spring 14 is fixedly connected to the slider 9, and the other end of the reset spring 14 is fixedly connected to the inner wall of the connecting seat 6. The reset spring 14 can drive the slider 9 to move and reset.

[0024] Furthermore, a push rod 13 is fixedly connected at equal intervals on one side of the slider 9. The push rod 13 is slidably connected to the connecting seat 6. A push block 8 is fixedly connected to the end of the push rod 13 away from the slider 9. Anti-slip protrusions 12 are fixedly connected at equal intervals on one side of the push block 8. The push rod 13 is moved by the push block 8, and the push rod 13 moves the slider 9.

[0025] Furthermore, the connecting rod 5 is made of insulating material, which enhances the safety of the device.

[0026] Furthermore, mounting blocks 7 are symmetrically fixedly connected to the outer side of the fixed base 3, which facilitates the installation and fixing of the fixed base 3 with bolts.

[0027] Working principle:

[0028] When the switch 4 needs to be opened, push the push block 8. The push block 8, through the push rod 13, causes the slider 9 to slide along the limit rod 15, compressing the return spring 14. The slider 9 then causes the locking block 11 to move away from the locking groove 10, thus pushing the sliding seat 2 upward. The movement of the sliding seat 2 causes the connecting rod 5 to rotate, which in turn causes the switch 4 to rotate, facilitating the opening of the switch 4. After the opening action is completed, release the push block 8. The return spring 14 causes the slider 9 to move and reset. The slider 9 then causes the locking block 11 to move into the corresponding locking groove 10, thereby locking the position of the connecting seat 6. When the switch 4 needs to be closed, push the push block 8. Push block 8 drives slider 9 to slide along limit rod 15 via push rod 13, compressing return spring 14. Slider 9 drives locking block 11 to move away from locking groove 10, thereby pushing sliding seat 2 downward. The movement of sliding seat 2 drives connecting rod 5 to rotate, which in turn drives switch 4 to rotate, facilitating closing of switch 4. After closing, push block 8 is released, and the return spring 14 drives slider 9 to move and reset. Slider 9 drives locking block 11 to move into the corresponding locking groove 10, thereby locking the position of connecting seat 6. This effectively prevents the disconnecting switch from malfunctioning due to vibration or other factors, greatly improving the safety and stability of equipment operation.
