DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general scale, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] The utility model provides an AC / DC switching module for an AC / DC dual-purpose motor. By cooperating with the provided AC / DC switching module components and emergency components, when in use, if the AC / DC switching module is overloaded and catches fire, an emergency response is immediately and automatically made, and dry powder fire extinguishing is directly applied to the entire range of the AC / DC switching module, thereby reducing the occurrence of potential safety hazards and improving the safety performance of the AC / DC switching module when in use.

[0033] Figure 1-5 The figure shows the overall structure of an AC / DC switching module of an AC / DC dual-purpose motor of the utility model. Figure 1-5 The main part of an AC / DC switching module of an AC / DC dual-purpose motor in this embodiment includes: an AC / DC switching module component and an emergency component.

[0034] The AC / DC switching module assembly is used in conjunction with the emergency assembly. Specifically, the AC / DC switching module assembly includes an AC / DC switching module housing 11, an AC / DC switching module body 12 disposed in the AC / DC switching module housing 11, a rectangular opening 13 provided on the top surface of the AC / DC switching module housing 11, a concave mounting plate 14 fixed at a corner of the rectangular opening 13, a cover plate 15 disposed above the AC / DC switching module housing 11, and a dry powder fire extinguishing agent bag 16 attached to the bottom surface of the cover plate 15;

[0035] During specific use, the cover plate 15 covers the surface of the AC / DC switching module housing 11, and the dry powder fire extinguishing agent bag 16 is located in the AC / DC switching module housing 11, so that emergency use is completed under the action of the emergency component.

[0036] The emergency component is used in an emergency state. Specifically, the emergency component includes a cross-cutting blade 21 fixed inside the AC / DC switching module housing 11, a rectangular notch 22 provided on the bottom surface of the concave mounting plate 14, a rotating shaft 23 provided on two opposite sides of the rectangular notch 22, a receiving plate 24 connected to the rotating shaft 23, a deep notch 25 provided on the bottom surface of the concave mounting plate 14, an electromagnetic sheet 26 fitted in the deep notch 25, and an iron sheet 27 provided below the electromagnetic sheet 26;

[0037] When overcurrent, overvoltage or short circuit occurs, the electromagnetic sheet 26 loses power supply and magnetic force. At this time, the iron sheet 27 and the electromagnetic sheet 26 are separated from each other, and the receiving plate 24 loses its limit. At this time, due to the gravity of the receiving plate 24, the receiving plate 24 directly drives the rotating shaft 23 to rotate, and the receiving plate 24 naturally sags with gravity. At this time, the covering plate 15 and the dry powder fire extinguishing agent package 16 lose their limit and fall. The dry powder fire extinguishing agent package 16 falls on the surface of the cross cutting blade 21, directly cutting the dry powder fire extinguishing agent package 16, and the fire extinguishing powder in the dry powder fire extinguishing agent package 16 is scattered and covers the surface of the AC / DC switching module body 12, so that the flames can be quickly covered to avoid safety hazards.

[0038] Working principle: the covering plate 15 covers the surface of the AC / DC switching module housing 11, and the dry powder fire extinguishing agent bag 16 is located in the AC / DC switching module housing 11, so that emergency use can be completed under the action of the emergency component. When overcurrent, overvoltage or short circuit occurs, the electromagnetic sheet 26 loses power supply and loses magnetic force. At this time, the iron sheet 27 and the electromagnetic sheet 26 are separated from each other, and the receiving plate 24 loses its limit. At this time, due to the gravity of the receiving plate 24, the receiving plate 24 directly drives the rotating shaft 23 to rotate, and the receiving plate 24 naturally droops with gravity. At this time, the covering plate 15 and the dry powder fire extinguishing agent bag 16 lose their limit and fall, and the dry powder fire extinguishing agent bag 16 falls on the surface of the cross cutting blade 21, directly cutting the dry powder fire extinguishing agent bag 16, and the fire extinguishing powder in the dry powder fire extinguishing agent bag 16 is scattered and covers the surface of the AC / DC switching module body 12, so that the flames can be quickly covered to avoid safety hazards.

[0039] Furthermore, by cooperating with the emergency component, when the emergency component fails, the physical structure can achieve a rapid emergency response effect, further ensuring the safety of the DC switching module during use. Specifically, the backup component includes a plastic plate 31 fixed to the front end of the receiving plate 24 and a horizontal plate 32 fixed to the front end of the plastic plate 31.

[0040] One end of the covering plate 15 is placed on the surface of the horizontal plate 32 .

[0041] The weight of the plastic plate 31 is greater than the total weight of the cover plate 15 and the dry powder fire extinguishing agent package 16;

[0042] If the emergency component fails, the electromagnetic sheet 26 always attracts the iron sheet 27 for limiting, and when a fire occurs in the AC / DC switching module housing 11, the flame will burn the plastic plate 31, and the plastic plate 31 will be melted and broken. At this time, the covering plate 15 placed on the surface of the horizontal plate 32 at one end will fall directly, and the dry powder fire extinguishing agent bag 16 will naturally extinguish the fire, and emergency fire fighting can still be achieved.

[0043] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
