Description

Technical Field

[0001] This utility model relates to the field of high-voltage electrical equipment technology, and in particular to a multi-dimensional drive device. Background Technology

[0002] High-voltage electrical equipment similar to longitudinal rotary isolation vacuum circuit breakers have two working modes in their three-dimensional transmission chain: linear drive and rotary drive, in order to drive the transmission chain to open or close the arc-extinguishing chamber of the circuit breaker. However, this transmission method requires a large installation space, and the mechanical structure of the transmission interlock is relatively complex, making it unsuitable for digital and intelligent upgrades. Therefore, a drive device is needed to solve a series of problems caused by the mechanical transmission chain being constrained by the arrangement of three-dimensional drive in a confined space. Utility Model Content

[0003] To address the problems mentioned above in the background technology, this application provides a multi-dimensional drive device that can be applied to equipment such as longitudinal-rotary isolation vacuum circuit breakers. It serves as a central conversion bridge between linear drive and rotary drive in a three-dimensional transmission chain, simplifying the complex overall structure and reducing the problem of mechanical transmission chains being constrained by installation space.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A multi-dimensional driving device, comprising:

[0006] The first connector includes a first bolt with a first external thread at one end and an external plug that is hollow at the other end, the external plug having a first internal thread and a countersunk hole;

[0007] A cylindrical head bolt includes a cylindrical head and a second bolt with a second external thread, the cylindrical head being received within an external plug, and the second bolt extending out of the external plug and having a first through hole extending radially through it.

[0008] A locking nut, the locking nut including a third bolt with a third external thread, the third external thread engaging with the first internal thread, the locking nut having a hollow through channel along the axial direction;

[0009] The second connector includes a fourth bolt with a fourth external thread at one end and a hollow inner plug at the other end. The inner plug has a second internal thread and a second through hole that extends radially through it. The second through hole corresponds to the first through hole. The second internal thread is screwed into and fixed with the second external thread. After the inner plug is assembled with the through channel, a gap is left.

[0010] After the second bolt is screwed into the hollow inner plug and fixed, the elastic cylindrical pin passes through the first through hole and the second through hole for fixed connection.

[0011] Preferably, the first connector and the second connector are both integrally formed structures, the diameter of the first bolt is smaller than that of the outer plug, the diameter of the countersunk hole is larger than that of the cylindrical head, and the depth of the countersunk hole is greater than that of the cylindrical head; the diameter of the fourth bolt is smaller than that of the inner plug.

[0012] Preferably, the elastic cylindrical pin has an axially oriented long groove, and the circumferential angle corresponding to the long groove is greater than 5 degrees and less than 45 degrees.

[0013] Preferably, the material of the elastic cylindrical pin is stainless steel or carbon steel.

[0014] Preferably, the third external thread of the locking nut is coated with anaerobic adhesive.

[0015] The beneficial effects of this utility model are as follows: After being installed on the circuit breaker, the first joint of the multi-dimensional drive device is fixed and the second joint can rotate. When the disconnecting switch is rotated, the circuit breaker spring operating mechanism is fixedly installed. The dual-function operating mechanism of the circuit breaker and the disconnecting switch is integrated, making the five-proof mechanical interlocking structure of the disconnecting switch and the circuit breaker simple and reliable. The second joint can rotate at any angle, such as 45°, 90°, 180°, or 360°, making the operation flexible. The entire multi-dimensional drive device has a simple structure and few parts, which can greatly reduce the installation space occupied. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. The components of this utility model, typically described and shown in the drawings herein, can be arranged and designed in various different configurations. Therefore, the following detailed description of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] Please see the appendix Figure 1-3 To address the problems in the background technology, this utility model provides a multi-dimensional drive device that can be applied to equipment such as longitudinal-rotary isolation vacuum circuit breakers. It serves as a central conversion bridge between linear drive and rotary drive in a three-dimensional transmission chain, simplifying the complex overall structure and reducing the problem of mechanical transmission chains being constrained by installation space.

[0022] Specifically, a multi-dimensional driving device includes:

[0023] The first connector 1 includes a first bolt 101 with a first external thread at one end and an external plug 102 that is hollow at the other end. A countersunk hole 103 is formed in the center of the external plug 102, and the sidewall of the countersunk hole 103 has a first internal thread.

[0024] The cylindrical head bolt 2 includes a cylindrical head 201 and a second bolt 202 with a second external thread. The cylindrical head 201 is accommodated in the external plug 102, and the second bolt 202 extends out of the external plug 102 and has a first through hole that extends radially through it.

[0025] The locking nut 4 includes a third bolt 402 with a third external thread, the third external thread engaging with the first internal thread, and the locking nut 4 having a hollow through channel 401 along the axial direction;

[0026] The second connector 5 includes a fourth bolt 501 with a fourth external thread at one end and an inner plug 502 that is hollow at the other end. The inner plug 502 has a second internal thread and a second through hole that extends radially through it. The second through hole corresponds to the first through hole. The second internal thread of the inner plug 502 can be screwed into and fixed with the second external thread of the cylindrical head 201. After the inner plug 502 is inserted into the through channel 401 of the locking nut 4 for assembly, there is a gap between the two, which facilitates the rotation of the second connector 5.

[0027] After the second bolt 202 is screwed into the hollow inner plug 502 and fixed, the elastic cylindrical pin 3 passes through the first through hole and the second through hole for fixed connection.

[0028] The first connector 1 and the second connector 5 are both integrally formed structures. The diameter of the first bolt 101 is smaller than that of the outer plug 102, the diameter of the countersunk hole 103 is larger than that of the cylindrical head 201, and the depth of the countersunk hole 103 is greater than that of the cylindrical head 201. The diameter of the fourth bolt 501 is smaller than that of the inner plug 502. The elastic cylindrical pin 3 has an axially oriented long groove, and the circumferential angle corresponding to the long groove is greater than 5 degrees and less than 45 degrees. In this embodiment, 10 degrees is preferred. The material of the elastic cylindrical pin 3 is stainless steel, but carbon steel can also be used, but the corresponding angle is preferably 15 degrees.

[0029] Please refer to Figure 3 During assembly, the inner plug 502 of the second connector 5 is inserted into the through channel 401 of the locking nut 4, and the second bolt 202 of the cylindrical head bolt 2 is screwed into the inner plug 502 until the cylindrical head 201 abuts against one end of the inner plug 502. At this time, the second through hole and the first through hole are connected, and the elastic cylindrical pin 3 is inserted for fixation. The second connector 5 and the cylindrical head bolt 2 are then connected as a whole. After assembly, refer to... Figure 1 and 2 After applying anaerobic adhesive to the third external thread of the locking nut 4, it is screwed into the countersunk hole 103 of the outer plug 102 of the first connector 1 for fixation. At this time, the other end of the cylindrical head 201 abuts against the inner wall of the countersunk hole 103. After the thread is tightened, the second connector 5 and the cylindrical head bolt 2 can rotate together in the countersunk hole 103. The end of the locking nut 4 forms a horizontal limit on the cylindrical head 201, but does not constitute a limit on circumferential rotation, so that the first connector 1 and the second connector 5 together form a multi-dimensional driving device through the locking nut 4 and the cylindrical head bolt 2.

[0030] One end of the multi-dimensional drive device, bolt 101, is connected to the output crank arm of the operating mechanism of the isolation vacuum circuit breaker, and the other end, bolt 501, is connected to the transmission component that drives the arc-extinguishing chamber of the isolation vacuum circuit breaker to open or close. During the circuit breaker's opening or closing operation, the multi-dimensional drive device moves back and forth in a linear motion, driving the transmission chain to open or close the arc-extinguishing chamber of the circuit breaker. When the rotating mechanism of the isolation vacuum circuit breaker drives the vacuum arc-extinguishing chamber pole to rotate counterclockwise or clockwise, the first connector 1 of the multi-dimensional drive device remains stationary, while the second connector 5 can rotate clockwise or counterclockwise with the pole, thus realizing the isolation closing or opening operation.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
