Description

Technical Field

[0001] The utility model relates to the field of environmental protection cabinets, and in particular to an isolation mechanism on an environmental protection cabinet. Background Art

[0002] The environmental protection cabinet is an environmental protection gas electrical cabinet. The environmental protection gas is used for arc extinguishing during segmentation. Sometimes, vacuum is also used for arc extinguishing. The Chinese utility model patent application number: CN202223219321.X proposes an interlocking mechanism on the environmental protection cabinet. The environmental protection cabinet includes an isolating switch and a circuit breaker. The isolating switch includes a first bracket, on which a closing and opening operating lever, a grounding operating lever and a front panel are installed. The front panel is provided with a closing and opening operating hole and a grounding operating hole, and a baffle is also arranged on the front panel along the horizontal sliding; the circuit breaker includes a closing operating shaft with a limit plate; the interlocking mechanism includes a lock plate and an interlocking assembly, the lock plate is arranged on the front panel along the vertical sliding, and the lower end of the baffle is provided with a linkage recess for the upper end of the lock plate to be embedded in the opening position, and the lower end of the lock plate is linked to the interlocking assembly, and the baffle slides horizontally to cause the lock plate to slide down, so that the lock plate drives the interlocking assembly to lock or disengage from the limit plate. The utility model can prevent other personnel from mistakenly operating the closing operation shaft of the circuit breaker when the operator operates the opening and closing operation lever or the grounding operation lever of the isolating switch, and can play the effect of protecting the environmental protection cabinet.

[0003] However, although the interlocking mechanism on the existing environmental protection cabinet can achieve the effect of limiting, in actual operation, due to the lack of an effective limit buffer structure, the isolation knife often collides hard when approaching the limit position. This impact not only produces noise and vibration, but more importantly, under the cumulative effect over a long period of time, it will cause increased wear of the internal parts of the isolation mechanism and even cause the isolation knife to deviate and shake; thus causing unnecessary damage to the equipment in the cabinet and even threatening the safety of the operator. Therefore, we have made improvements to this and proposed an isolation mechanism on the environmental protection cabinet. Utility Model Content

[0023] A gear shaft hole 7 is provided at the center of the buffer disk 602 and the buffer damping turntable 601, and the rotating shaft 3 penetrates into the gear shaft hole 7. An isolation turntable 4 is provided on the outer side of the buffer disk 602. The isolation knob 8 is electrically connected to the drive motor 2. It also includes an electromagnetic lock 9, on which a lock spring 901 is provided, and the electromagnetic lock 9 is provided at the lower part of the main frame 1 of the upper isolation mechanism. A closing button 10 is provided on the main frame 1 of the upper isolation mechanism, and the closing button 10 is connected to the closing pneumatic motor 11, and the closing pneumatic motor 11 is connected to the closing contact rod 12 through the motor shaft. The ends of the closing contact rod 12 are provided with closing connection contacts 13 at the upper and lower ends, and a layer of copper sheet is provided on the closing connection contact 13. The upper isolation mechanism main frame 1 is provided with a connecting plate 14, the upper and lower parts of the connecting plate 14 are provided with connecting slots 1401, the connecting slots 1401 are provided with fastening bolts 1402, and the side of the connecting plate 14 is provided with a latch rod 15. Four buffer springs 603 are provided in an annular array and are symmetrical to each other.

[0024] The main frame 1 of the upper isolation mechanism provides the support structure of the entire isolation mechanism, ensuring the stable installation and coordinated work of each component, and improving the durability and stability of the overall mechanism. The drive motor 2 can accurately control the rotation of the rotating shaft 3 and the isolation turntable 4, realize the smooth movement of the isolation rod 401, thereby improving the accuracy and response speed of the operation. The use of the rotating shaft 3 and the isolation turntable 4 effectively converts the power of the drive motor 2 into the linear motion of the isolation rod 401, and realizes the rapid positioning and control of the isolation knife. The isolation rod 401 directly participates in the isolation action, while the limit rod 5 is used to determine the final position of the isolation rod 401. The combination of the two ensures the accuracy and reliability of the isolation action. The limit buffer assembly 6 effectively absorbs the impact force of the isolation rod 401 when it approaches the limit position, prevents hard collision, reduces noise and vibration, and prolongs the service life of the mechanism. The gear shaft hole 7 enables the rotating shaft 3 and the buffer disk 602 to rotate synchronously, ensuring the smooth progress of the buffer action and improving the coordination of the entire mechanism. The closing button 10 is used to start the closing pneumatic motor 11 to achieve remote or automatic control and improve the convenience and efficiency of operation. The coordinated use of the closing contact rod 12 and the closing connection contact 13 ensures that the electromagnetic lock 9 can accurately cut off the power and achieve the smooth unlocking of the isolation rod 401. The use of the connecting plate 14 and the fastening bolt 1402 allows the entire isolation mechanism to be easily installed on the environmental protection cabinet, improving the flexibility of installation and the applicability of the mechanism; the four mutually symmetrical buffer springs 603 ensure the uniform distribution of the buffer force, improve the stability of the buffer effect and the smooth movement of the isolation rod 401.

[0025] The working principle of the isolation mechanism on the environmental protection cabinet is mainly to achieve precise control of the isolation knife through the cooperation of the driving motor 2, the rotating shaft 3 and the isolation turntable 4, and at the same time use the limit buffer component 6 to reduce impact and wear to ensure the safety and reliability of operation.

[0026] The core of the isolation mechanism on the environmental protection cabinet is the drive motor 2, which is the power source of the entire mechanism. After the drive motor 2 is started, it will drive the rotating shaft 3 to rotate, and then drive the isolation turntable 4 to rotate. The isolation rod 401 set on the side of the isolation turntable 4 moves accordingly, and when it approaches the limit position, the limit buffer assembly 6 begins to play a role. The limit buffer assembly 6 is composed of a buffer damping turntable 601 and a buffer magnetic disk 602, which are connected to the rotating shaft 3 through the gear shaft hole 7 to maintain synchronous rotation. The buffer magnetic disk 602 is provided with four disk slots 6021 in an annular array, and each slot has a buffer spring 603. When the isolation rod 401 approaches the limit position, the buffer spring 603 is gradually compressed, generating a reverse force, which gradually slows down the speed of the isolation rod 401 and finally stops smoothly, avoiding hard collisions and noise.

[0027] During the limit buffering process, the electromagnetic lock 9 plays a locking role. When the isolation rod 401 reaches the limit position and stops, the lock spring 901 on the electromagnetic lock 9 pops out the lock and locks the isolation rod 401 to ensure that it will not move due to external force. This design not only improves the stability of the mechanism, but also enhances the safety of operation. When it is necessary to release the lock, the operator only needs to press the closing button 10, start the closing pneumatic motor 11, and drive the closing contact rod 12 to move downward through the motor shaft, so that the closing connection contact 13 contacts the lock on the electromagnetic lock 9, thereby de-energizing the electromagnetic lock 9, contracting the lock, and releasing the isolation rod 401. Finally, the drive motor 2 is reversed to return the isolation rod 401 to the initial position, completing a complete working cycle.

[0028] The working principle of the isolation mechanism on the environmental protection cabinet involves the synergy of multiple components, including the drive motor 2, the rotating shaft 3, the isolation turntable 4, the limit buffer component 6, the electromagnetic lock 9, etc. The precise coordination of these components not only realizes the precise control of the isolation knife, but also greatly improves the safety and reliability of the operation, and reduces the wear of internal parts and the offset of the isolation knife.

[0029] The specific working process of the isolation mechanism on the environmental protection cabinet is as follows:

[0030] The driving motor 2 is started to make the rotating shaft 3 drive the isolation turntable 4 to rotate.

[0031] When the isolation rod 401 approaches the limit position, the limit buffer assembly 6 starts to function, and the buffering effect on the isolation rod 401 is achieved through the interaction between the buffer damping turntable 601 and the buffer magnetic disk 602 .

[0032] When the isolation rod 401 reaches the limit position, the buffer spring 603 is compressed to generate a reverse force, causing the isolation rod 401 to slowly stop moving, thereby avoiding a hard collision.

[0033] After the isolation rod 401 stops moving, the lock element spring 901 on the electromagnetic lock 9 pops out the lock element, locking the isolation rod 401 at the limit position to ensure that it will not move due to external force.

[0034] When the lock needs to be released, the closing button 10 is pressed, the closing pneumatic motor 11 is started, and the closing contact rod 12 is driven to move downward through the motor shaft.

[0035] Closing contacts 13 are provided at the upper and lower ends of the closing contact rod 12. When the closing contact rod 12 moves downward, the closing contact 13 contacts the lock element on the electromagnetic lock 9, so that the electromagnetic lock 9 is powered off, the lock element contracts, and the isolation rod 401 is unlocked.

[0036] After unlocking, the driving motor 2 is reversed to return the isolation rod 401 to the initial position, completing a complete working process. The isolation mechanism on the environmental protection cabinet realizes effective limiting and buffering of the isolation rod 401, solving the problems existing in the existing interlocking mechanism in actual operation.
