Description

Technical Field

[0001] The utility model relates to the technical field of tripping mechanisms, and particularly to an automatic tripping mechanism of a permanent magnet operating mechanism. Background Art

[0002] Traditional tripping mechanisms usually use spring devices to achieve tripping and closing actions. The spring stores energy during tripping and then releases the energy to push the mechanism to complete the tripping action, while during closing, the spring needs to be recompressed to complete the closing action.

[0003] Chinese Patent with the publication number CN220085864U discloses a permanent magnet operating mechanism with rapid tripping. The elastic tension of the tripping reaction spring can cause the driving main shaft to trip. When the magnetic suction force received by the driving main shaft decreases and the resultant force in the closing direction received by the driving main shaft is less than the tension of the tripping reaction spring, the driving main shaft moves faster in the tripping direction. The cam rotation can push the tripping limit block to move, and the movement of the tripping limit block can cause the driving main shaft to move.

[0004] In the prior art, although the functions of tripping and closing are achieved to a certain extent, the spring may deteriorate, be damaged or fail after long-term use, and requires regular maintenance and replacement, increasing the maintenance cost and downtime.

[0005] Therefore, how to design an automatic tripping mechanism of a permanent magnet operating mechanism has become the problem that needs to be solved currently. Summary of the Utility Model

[0025] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more, unless otherwise specifically defined.

[0026] As Figures 1-4 shown, the present utility model provides a technical solution: an automatic opening mechanism of a permanent magnet operating mechanism, including a support assembly 1, a magnetic push assembly 2, and a connection assembly 3. The magnetic push assembly 2 is arranged at the upper end of the support assembly 1, and the connection assembly 3 is arranged on the right side of the support assembly 1. The magnetic push assembly 2 includes a metal column 21, and a tripping coil 22 is installed outside the metal column 21. A permanent magnet 24 is movably installed on the right side of the support assembly 1, and the permanent magnet 24 corresponds to the metal column 21. The support assembly 1 is the basis of the entire mechanism. In the magnetic push assembly 2, the tripping coil 22 changes the magnetic state of the metal column 21, pushes the permanent magnet 24 to move, and further drives the connection assembly 3 to perform an opening operation. The metal column 21 is subjected to the adsorption of the permanent magnet 24 when the tripping coil 22 is not activated, maintaining the closed state of the connection assembly 3.

[0027] The support assembly 1 includes a support base 11, and a support bracket 12 is fixed at the upper end of the support base 11. The metal column 21 is fixed inside the support bracket 12. The support base 11 provides a stable foundation for the entire mechanism, and the support bracket 12 is used to fix the position of the metal column 21.

[0028] On both sides of the upper end of the permanent magnet 24, connecting rods 241 are fixed. The permanent magnet 24 is movably installed on the upper right side of the support bracket 12 through the connecting rods 241. The connecting rods 241 provide movable support for the permanent magnet 24, enabling the permanent magnet 24 to move under the action of the magnetic push assembly 2.

[0029] On the left side of the opening coil 22, a brake wire terminal 23 is provided. The brake wire terminal 23 is installed through the bottom of the support base 11. The layout design enables the power supply line to be directly and conveniently connected to the opening coil 22, reducing the complexity of the line layout and improving the integration and reliability of the entire mechanism.

[0030] The connection assembly 3 includes a connection block 31. The connection block 31 is fixed on the right side of the permanent magnet 24. Two groups of first wiring terminals 32 are fixed inside the connection block 31. The connection block 31 is fixed on the right side of the permanent magnet 24. This design enables the connection block 31 to be directly driven to move when the permanent magnet 24 moves. The first wiring terminals 32 are electrical connection points between the power supply and the load, responsible for transmitting electrical energy. The permanent magnet 24 drives the connection block 31 and the first wiring terminals 32 to move to another position. At this time, the connection between the power supply and the load is disconnected, realizing automatic opening of the power supply.

[0031] On the right side of the support base 11, two groups of second wiring terminals 33 are provided. The two groups of first wiring terminals 32 correspond to the second wiring terminals 33. The second wiring terminals 33 cooperate with the first wiring terminals 32 to realize effective connection and disconnection between the power supply and the load.

[0032] Between the two groups of second wiring terminals 33, an arc extinguishing plate 34 is provided. The arc extinguishing plate 34 is fixed on the upper end of the support base 11. The main function of the arc extinguishing plate 34 is to extinguish the possible arcs generated during the opening process, preventing the arcs from damaging the mechanism and surrounding equipment.

[0033] The working process of the present utility model: When the mechanism is in the initial state, the opening coil 22 is not activated. The metal column 21 is adsorbed by the permanent magnet 24 and remains at a fixed position inside the support bracket 12. The permanent magnet 24 is movably installed on the upper right side of the support bracket 12 through the connecting rods 241. The connection block 31 is fixed on the right side of the permanent magnet 24, and the first wiring terminals 32 fixed inside the connection block 31 correspond to the second wiring terminals 33 provided on the right side of the support base 11. At this time, a closed circuit is formed between the power supply and the load, and the load is normally powered. The arc extinguishing plate 34 is fixed on the upper end of the support base 11 and is in a standby state, ready to extinguish the possible arcs when necessary;

[0034] When the power needs to be cut off, the opening coil 22 is activated through the control device. After the opening coil 22 is energized, an electromagnetic field is generated, changing the magnetic state of the metal column 21. Due to the change in the magnetism of the metal column 21, a repulsive force is generated between the metal column 21 and the permanent magnet 24, pushing the permanent magnet 24 to move to the right. Since the permanent magnet 24 is movably connected to the support bracket 12 through the connecting rod 241, it can move smoothly. The movement of the permanent magnet 24 drives the connecting block 31 and the first terminal 32 inside it to move together, causing the connection between the first terminal 32 and the second terminal 33 to be disconnected. As the connection between the first terminal 32 and the second terminal 33 is disconnected, the circuit between the power supply and the load is cut off, and the load loses power supply, completing the opening operation.

[0035] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
