Description

Technical Field

[0001] This utility model belongs to the technical field of dual power automatic transfer switch, specifically relating to an automatic transfer device for a dual power automatic transfer switch. Background Technology

[0002] An automatic transfer switch (ATS) is an electrical device used to automatically switch between two power sources (such as a main power source and a backup power source) to ensure continuous power supply to critical loads. ATSs are widely used in important locations where power outages are unacceptable, such as high-rise buildings, residential communities, hospitals, airports, docks, fire protection facilities, metallurgical plants, chemical plants, and textile mills.

[0003] Most existing dual-power automatic transfer switches have manual / automatic switching functions. These mechanisms allow for switching between manual and automatic modes, adapting to different scenarios and balancing operational flexibility with system reliability. However, existing manual / automatic switching mechanisms are complex in design and contain numerous components, leading to jamming or even failure during the switching process. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an automatic switching device for a dual-power automatic transfer switch, which can effectively and reliably switch between manual and automatic modes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic switching device for a dual-power automatic transfer switch includes a housing, a switching mechanism disposed within the housing, a manual / automatic switching mechanism disposed within the housing, and a control circuit board disposed within the housing. The manual / automatic switching mechanism includes a sliding plate seat, a sliding plate, a push plate, and a micro switch disposed within the housing. An elastic reset member is disposed between the sliding plate seat and the sliding plate. The push plate slides relative to the housing and has an electric position and a manual position. The micro switch is disposed on the control circuit board and cooperates with the push plate. When the push plate slides to the electric position, the push plate causes the micro switch to connect the power supply to the control circuit board, and the driving force of the push plate causes the sliding plate to compress the elastic reset member and close the operating hole of the housing. When the push plate slides to the manual position, the push plate causes the micro switch to cut off the power supply to the control circuit board, and the sliding plate loses the driving force of the push plate. The elastic force of the elastic reset member causes the sliding plate to open the operating hole of the housing.

[0006] In some embodiments, the skateboard seat is provided with a guide post, the skateboard is provided with a guide arm on the side facing the push plate, the guide arm is provided with a guide hole, and the guide post is inserted into the guide hole of the guide arm, thus forming a sliding connection between the guide arm and the guide post.

[0007] In some embodiments, the elastic reset member is a compression spring, which is fitted onto the guide post, with one end of the compression spring abutting against the slide plate seat and the other end of the compression spring abutting against the guide arm.

[0008] In some embodiments, the slide plate seat covers the pressure plate on the push plate, the pressure plate is provided with a sliding groove, the push plate is provided with a toggle piece inserted in the sliding groove, and the toggle piece is provided with a toggle sleeve exposed outside the housing.

[0009] In some embodiments, the push plate is provided with a guide sliding hole, and the pressure plate is provided with a boss inserted into the guide sliding hole, forming a sliding connection between the pressure plate and the boss.

[0010] In some embodiments, the push plate has a pushing protrusion on the side facing the slide plate, the slide plate is provided with a receiving groove for accommodating the pushing protrusion, one side of the receiving groove has a driving ramp for the pushing protrusion to slide, the slide plate is provided with a limiting plane connected to the driving ramp, and the pushing protrusion moves with the push plate and slides back and forth between the receiving groove and the limiting plane.

[0011] In some embodiments, the push plate has a trigger piece for triggering a micro switch. The trigger piece moves with the push plate and triggers the micro switch, thereby turning the micro switch on or off.

[0012] In some embodiments, the conversion mechanism is provided with a locking mechanism on its frame. The locking mechanism includes a padlock and a locking micro switch for controlling the power supply of the motor. The locking micro switch is provided on the frame and cooperates with the padlock. One end of the padlock passes through the locking hole of the housing and is provided with a padlock hole. The other end of the padlock has a locking piece. The conversion shaft of the conversion mechanism is provided with a socket for the locking piece to be inserted.

[0013] In some embodiments, the other end of the padlock has a triggering ramp that cooperates with a locking micro switch. The triggering ramp moves with the padlock and triggers the locking micro switch, thereby enabling the locking micro switch to be turned on or off.

[0014] In some embodiments, the padlock is provided with a sliding hole, and the mechanism frame is provided with a guide rod inserted into the sliding hole, thereby forming a sliding connection between the padlock and the guide rod.

Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0026] like Figure 1-3As shown, an automatic switching device for a dual-power automatic transfer switch includes a housing 1, a switching mechanism 4 disposed within the housing 1, a manual / automatic switching mechanism 2 disposed within the housing 1, and a control circuit board 5 disposed within the housing 1. The manual / automatic switching mechanism 2 includes a sliding plate seat 21 disposed within the housing 1, a sliding plate 22 slidably disposed on the sliding plate seat 21, a push plate 23, a micro switch 24 disposed on the control circuit board 5, and an elastic reset member 25. The push plate 23 slides relative to the housing 1 and has an electric position and a manual position. When the push plate 23 slides to the electric position, the driving force of the push plate 23 causes the sliding plate 22 to compress the elastic reset member 25 and block it in the manual operation hole 11 of the housing 1. The push plate 23 triggers the micro switch 24, causing the micro switch 24 to connect the power supply to the control circuit board 5. When the push plate 23 slides to the manual position, the sliding plate 22 loses the driving force of the push plate 23, the elastic force of the elastic reset member 25 causes the sliding plate 22 to reset, the micro switch 24 loses the driving force of the push plate 23, and the micro switch 24 disconnects the power supply to the control circuit board 5.

[0027] like Figure 2-4 As shown, a guide post 211 is provided on the skateboard seat 21, and a guide arm 221 is provided on the side of the skateboard 22 facing the push plate 23. A guide hole 222 is provided on the guide arm 221, and the guide post 211 passes through the guide hole 222 of the guide arm 221, forming a sliding connection between the guide arm 221 and the guide post 211. The skateboard slides on the guide post of the skateboard seat, ensuring reliable movement of the skateboard on the skateboard seat and preventing the skateboard from jamming or getting stuck. The elastic reset element 25 is a compression spring, which is fitted onto the guide post 211, with one end of the spring abutting against the skateboard seat 21 and the other end abutting against the guide arm 211. The compression spring is fitted onto the guide post of the skateboard seat, facilitating the assembly of the compression spring with the skateboard seat and the skateboard, and ensuring that the compression spring can reliably drive the skateboard to reset. A pressure plate 26 covers the push plate 23 on the skateboard base 21. The pressure plate 26 has a sliding groove 261, and the push plate 23 has an actuating piece 231 that passes through the sliding groove 261. The actuating piece 231 has an actuating sleeve 27 that protrudes from the housing 1. The push plate is slidably positioned in the sliding groove of the pressure plate by the actuating piece, thus ensuring that the push plate can reliably move on the skateboard base. Furthermore, the actuating sleeve on the actuating piece allows the push plate to be driven by actuating the actuating sleeve during operation, making operation more convenient.

[0028] like Figure 3 and 5As shown, the push plate 23 is provided with a guide sliding hole 232, and the pressure plate 26 is provided with a boss 262 that passes through the guide sliding hole 232, forming a sliding connection between the pressure plate 26 and the boss 262. The boss on the pressure plate guides the push plate, thereby ensuring that the push plate can move reliably. The push plate 23 has a pushing protrusion 233 on the side facing the slide plate 22. The slide plate 22 is provided with a receiving groove 223 for accommodating the pushing protrusion 233. One side of the receiving groove 223 has a driving inclined surface 224 for the pushing protrusion 233 to slide. The slide plate 22 is provided with a limiting plane 225 connected to the driving inclined surface 224. The pushing protrusion 233 moves with the push plate 23 and slides back and forth between the receiving groove 223 and the limiting plane 225. The push plate 23 has a trigger piece 234 for triggering the micro switch 24. The trigger piece 234 moves with the push plate 23 and triggers the micro switch 24, thereby turning the micro switch 24 on or off.

[0029] like Figure 1 and 2 As shown, a locking mechanism 6 is provided on the frame 41 of the conversion mechanism 4. The locking mechanism 6 includes a padlock 61 and a locking micro switch 62 for controlling the power supply of the motor 3. The locking micro switch 62 is mounted on the frame 21 and cooperates with the padlock 61. One end of the padlock 61 passes through the locking hole 12 of the housing 1 and has a padlock hole 611. The other end of the padlock 61 has a locking piece 612. The conversion shaft 42 of the conversion mechanism 4 has an insertion hole 421 for the locking piece 612 to be inserted. During maintenance, the locking mechanism can lock the automatic conversion device, thereby ensuring the personal safety of maintenance personnel. During operation, when the automatic conversion device is in the double-open position, the padlock piece is pulled out of the housing and the padlock is hooked into the padlock hole. The locking micro switch loses the driving force of the padlock piece and disconnects the motor power supply, thereby realizing the electric function locking. The locking piece of the padlock is inserted into the insertion hole of the conversion shaft, and the operator cannot manually rotate the conversion shaft, thereby realizing the manual operation function locking. The other end of the padlock component 61 has a triggering ramp 613 that cooperates with the locking micro switch 62. The triggering ramp 613 moves with the padlock component 61 and triggers the locking micro switch 62, thus turning the locking micro switch 62 on or off. The padlock component triggers the locking micro switch through the triggering ramp, which ensures that the padlock component can reliably drive the contact of the locking micro switch, thereby improving the working reliability of the locking mechanism. The padlock component 61 is provided with a sliding hole 614, and the mechanism frame 41 is provided with a guide rod 411 that passes through the sliding hole 614, forming a sliding connection between the padlock component 61 and the guide rod 411. The padlock component is slidably mounted on the guide rod of the mechanism frame, which ensures that the padlock component can reliably move on the mechanism frame, thereby improving the working reliability of the locking mechanism.

[0030] This manual / automatic switching mechanism adopts a sliding plate structure design, which reduces the number of parts and simplifies the structure, preventing the sliding plate from jamming and improving the reliability of manual / automatic switching. Furthermore, the modular design allows for modular assembly of the switching mechanism and the housing, resulting in higher assembly efficiency.

[0031] When the manual / automatic switching mechanism is in operation, when the push plate slides to the electric position, it triggers a micro switch. The micro switch connects the power supply to the control circuit board, and the pusher protrusion of the push plate slides from the receiving groove along the drive ramp to the limit plane. The pusher protrusion drives the slide plate to move, compressing the spring. The slide plate closes the operating hole of the housing, making manual operation impossible. When the push plate slides to the manual position, it triggers a micro switch, disconnecting the power supply to the control circuit board, disabling the electric function, and the slide plate loses the limiting force of the pusher protrusion. The slide plate resets and opens the manual operating hole of the housing.

[0032] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
