Description

Technical Field

[0001] This utility model relates to the field of power module drive technology, and in particular to an intelligent mechanism drive unit. Background Technology

[0002] The contact of a plug-in circuit breaker is a key component in a circuit breaker that enables circuit switching. It consists of a moving contact and a contact base. The moving contact can be inserted into the contact base for close contact to conduct power. When the equipment is running normally, the circuit is stably connected. When the circuit breaker module fails, it can be quickly separated by the mechanism and then quickly replaced with a new module. It is widely used in various medium and low voltage power distribution applications. With its good contact performance and mechanical properties, it ensures the safe and stable operation of the power system.

[0003] In mining equipment, the insertion and removal of power modules and sockets is often done manually. The control method is relatively simple. Manual insertion and removal relies on human operation, which is suitable for most application scenarios. However, it is difficult to deal with situations with large specifications and high insertion and removal force requirements. Furthermore, if the mechanism malfunctions and other problems prevent normal operation of the manual method, it may cause damage to the mechanism due to brute force. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an intelligent mechanism drive unit for driving a power module to move closer to or away from a plug-in socket, including a drive component and a support component. The drive component is used to move the support component horizontally. The support component is detachably connected to the power module. The drive component includes a threaded transmission rod and a transmission sleeve. The transmission sleeve is fixedly connected to the support component. A sliding gear that can move along the axial direction of the transmission rod is sleeved on the transmission rod. The inner wall of the sliding gear is provided with several protrusions. When the sliding gear rotates, the protrusions drive the transmission rod to rotate.

[0006] As a preferred embodiment of the intelligent mechanism drive unit of this utility model, the transmission rod is provided with an external thread, and the external thread is provided with a plurality of strip grooves in the circumferential direction. The length direction of the strip grooves is parallel to the length direction of the screw.

[0022] Example

[0023] Reference Figures 1-4 This embodiment provides an intelligent mechanism drive unit for driving the power module 1 to move closer to or away from the plug-in 2. Specifically, it includes a drive component and a support component. The drive component is used to move the support component horizontally. The support component is detachably connected to the power module 1. The drive component includes a threaded transmission rod 401 and a transmission sleeve 404. The transmission sleeve 404 is fixedly connected to the support component. A sliding gear 405 that can move along the axial direction of the transmission rod 401 is sleeved on the transmission rod 401. The inner wall of the sliding gear 405 is provided with a plurality of protrusions 406. When the sliding gear 405 rotates, the protrusions 406 drive the transmission rod 401 to rotate.

[0024] The transmission rod 401 is provided with an external thread 402, and the external thread 402 is circumferentially provided with several strip grooves 403. The length direction of the strip grooves 403 is parallel to the length direction of the screw. The number of protrusions 406 is the same as the number of strip grooves 403, and the protrusions 406 can slide along the strip grooves 403. The support assembly includes a support frame 501 and a chassis frame 502 fixedly connected to the support frame 501. The chassis frame 502 is provided with a motor 503 and a gear set 504 connected to the output shaft of the motor 503. The gear set 504 meshes with a sliding gear 405.

[0025] The support frame 501 is snapped into the bottom of the power module 1, and the bottom of the support frame 501 is connected to the top of the chassis frame 502 by bolts. The transmission rod 401 has smooth ends, which are slidably connected to the sides of the chassis frame 502. The gear set 504 is rotatably connected to the inner wall of the chassis frame 502, and a fixing plate for supporting the gear set 504 is connected to one side of the gear set 504. The fixing plate is located inside the chassis frame 502 and is fixedly connected to the chassis frame 502.

[0026] The transmission sleeve 404 is fixedly connected to the chassis frame 502. One side of the sliding gear 405 is in contact with the inner wall of the chassis frame 502, and the other side of the sliding gear 405 is in contact with the transmission sleeve 404. When the transmission rod 401 rotates, the transmission sleeve 404, the sliding gear 405 and the chassis frame 502 move synchronously relative to the transmission rod 401.

[0027] The length of the protrusion 406 is greater than the pitch of the external thread 402. When the transmission rod 401 is manually rotated, the sliding gear 405 will also rotate synchronously, and the gear set 504 will idle at this time.

[0028] A base 3 is located below the chassis frame 502, and the base 3 is fixedly connected to the plug-in socket 2. Several rollers 505 are provided on the side of the chassis frame 502, and the rollers 505 overlap the edge of the base 3. The drive assembly includes a cover 407 located on one side of the chassis frame 502. The cover 407 is rotatably connected to the transmission rod 401. A locking rod 408 is provided inside the cover 407, which is used to fix the cover 407 and the base 3. A slide rail 506 is provided inside the chassis frame 502, and a slider 507 that cooperates with the slide rail 506 is connected to the transmission rod 401.

[0029] The base 3 has a hollow center and two parallel tracks on both sides. The rollers 505 have a stepped cross-section and overlap with the two parallel tracks, allowing them to move in the same direction. The slide rail 506 is fixedly connected to the chassis frame 502, and the slider 507 can slide on the slide rail 506.

[0030] The cover 407 has slots on both sides, and the base 3 is connected to a side plate, which also has corresponding slots. The locking rod 408 is slidably connected to the cover 407, and the end of the locking rod 408 is provided with a block that is the same shape and size as the slot.

[0031] In use, the locking lever 408 is moved to engage the locking block with the corresponding slot, thereby fixing the cover 407. The motor 503 is then started, and through the transmission of the gearbox and gear set 504, the sliding gear 405 and the transmission rod 401 slide synchronously and relative to each other. This, in turn, works with the transmission sleeve 404 to move the chassis frame 502 and the support frame 501, enabling the insertion and removal of the power module 1. Alternatively, a commonly used tool such as a universal joint or handle can be connected to the end of the transmission rod 401, allowing manual rotation of the transmission rod 401 to also perform the insertion and removal of the power module 1.

[0032] Importantly, although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible without substantially departing from the subject matter described in this application, such as changes in the size, structure, shape, and proportion of various elements, as well as variations in temperature, pressure, installation arrangement, material use, color, orientation, etc.; for example, an element shown as integrally formed may be composed of multiple parts or elements, and the position of the elements may be inverted or otherwise altered; therefore, all such modifications should be included within the scope of this invention, and other substitutions, modifications, alterations, and omissions may be made in the design, operation, and arrangement of the exemplary embodiments without departing from the scope of this invention.
