Description

Technical Field

[0001] This utility model relates to the field of power cabinet technology, and in particular to a quick-connection high-voltage power cabinet plug-in structure. Background Technology

[0002] In existing railway rail transit systems, a dual-power supply mode is generally adopted. When one power supply fails, the other power supply can promptly take over to ensure system stability. However, special situations sometimes occur, such as when one power supply is under maintenance and can only be supplied by the other power supply. If the voltage of the other power supply fails, a power supply vehicle is needed to supplement the power supply to ensure system operation. However, the connection between the existing power cabinet and the power supply vehicle is inconvenient, making it impossible to quickly connect the power supply vehicle to the power cabinet in the above situation. Therefore, the power cabinet needs to be improved, and a quick-connection structure is proposed. Summary of the Invention

[0003] To address the aforementioned issues, a quick-connect high-voltage power cabinet connection structure is provided, aiming to resolve the problems existing in the prior art.

[0004] The specific technical solution is as follows: A quick-connection high-voltage power cabinet plug-in structure includes a power cabinet body, a receiving component, and a plug-in component. The receiving component is disposed in the power cabinet body, and the plug-in component is disposed on a power supply vehicle. The receiving component includes multiple sockets, and the plug-in component includes multiple plugs adapted to the multiple sockets. When the power supply vehicle needs to supply power to the power cabinet body, the plug-in component can be inserted into the receiving component, so that the power supply vehicle and the power cabinet are electrically connected.

[0005] The aforementioned quick-connect high-voltage power cabinet plug-in structure also has the following features: the receiving component includes an upper limit body, a lower limit body, and multiple connecting bodies. The upper limit body and the lower limit body are symmetrically spaced apart. Both the upper limit body and the lower limit body are connected to the power cabinet body through the connecting bodies. The bottom surface of the upper limit body and the top surface of the lower limit body are provided with slots, and the upper and lower slots correspond one-to-one. A connecting protrusion is provided in the slot.

[0006] The aforementioned quick-connect high-voltage power cabinet plug-in structure also has the following features: the plug-in assembly includes multiple carriers, twice the number of movable abutments, and a drive separation part that drives the movable abutments to approach the carriers. The movable abutments are provided on both the upper and lower sides of the carriers, and two movable abutments on the same carrier are symmetrically distributed. The carrier has a receiving cavity, and the drive separation part is disposed in the receiving cavity. The drive separation part is connected to the movable abutment in a driving manner. When the carrier is inserted into the corresponding socket, the movable abutments enter the corresponding slots respectively.

[0007] The aforementioned quick-connect high-voltage power cabinet plug-in structure also has the following features: the movable abutment part includes a base post, a spring, a guide post, and a movable body. One end of the base post is connected to the support body. The spring surrounds the outer periphery of the support body, and one end of the spring is connected to the support body. The movable body has a groove on the side facing the support body, and the other end of the spring is connected to the bottom wall of the groove. A guide groove is formed on the top surface of the base post, and the guide post is disposed on the bottom wall of the groove. The end of the guide post facing the base post extends into the guide groove. A connecting groove is formed on the top surface of the movable body away from the support body, allowing the connecting protrusion to enter.

[0008] The aforementioned quick-connect high-voltage power cabinet plug-in structure also has the following features: the drive separation part includes a rotating shaft, a traction rope, and a rotating handle; the bottom wall of the guide groove has a traction groove for communicating with the receiving cavity; the rotating shaft is disposed in the receiving cavity; one end of the traction rope is connected to the guide post; the other end of the traction rope is connected to the rotating shaft; one end of the rotating handle is connected to one end face of the rotating shaft; and the other end of the rotating handle extends out of the receiving cavity and is outside the carrier. When the carrier is completely inserted between the upper limit body and the lower limit body, driving the rotating handle will cause the movable body to move toward the carrier until the connecting protrusion disengages from the connecting groove.

[0009] The aforementioned quick-connect high-voltage power cabinet plug-in structure also has the following feature: the end of the movable body that extends into the bayonet is set in an inclined state. When the movable body is gradually inserted into the bayonet, the connecting protrusion squeezes the inclined surface of the movable body, causing the movable body to gradually approach the carrier until the connecting protrusion enters the connecting groove.

[0010] In summary, the beneficial effects of this scheme are: The quick-connection high-voltage power cabinet plug-in structure provided by this utility model achieves a rapid plug-in effect while ensuring connection strength through the cooperation of the receiving component and the plug-in component. This quick-connection high-voltage power cabinet plug-in structure facilitates the rapid connection of power supply vehicles to the power cabinet. Attached Figure Description

Figure 5 This is a side view of the plug-in assembly of the quick-connect high-voltage power supply cabinet of this utility model. Figures 1-5 As shown, the quick-connect high-voltage power cabinet plug-in structure provided in this embodiment includes a power cabinet body 1, a receiving component, and a plug-in component. The receiving component is disposed in the power cabinet body 1, and the plug-in component is disposed on the power supply vehicle. The receiving component includes multiple sockets, and the plug-in component includes multiple plugs adapted to the multiple sockets. When the power supply vehicle is needed to supply power to the power cabinet body 1, the plug-in component can be inserted into the receiving component, so that the power supply vehicle and the power cabinet are electrically connected.

[0017] In the above embodiment, the receiving component includes an upper limit body 2, a lower limit body 3 and multiple connecting bodies 4. The upper limit body 2 and the lower limit body 3 are symmetrically spaced apart. Both the upper limit body 2 and the lower limit body 3 are connected to the power cabinet body 1 through the connecting bodies 4. The bottom surface of the upper limit body 2 and the top surface of the lower limit body 3 are provided with slots, and the upper and lower slots correspond one to one. Connecting protrusions are provided in the slots.

[0018] In the above embodiment, the plug-in assembly includes multiple carriers 5, twice the number of movable abutments of the carriers 5, and a drive separation part that drives the movable abutments to approach the carriers 5. Movable abutments are provided on both the upper and lower sides of the carriers 5. Two movable abutments on the same carrier 5 are symmetrically distributed. A receiving cavity is opened in the carrier 5. The drive separation part is disposed in the receiving cavity. The drive separation part is connected to the movable abutment in a transmission manner. When the carrier 5 is inserted into the corresponding socket, the movable abutments enter the corresponding slots respectively.

[0019] In the above embodiment, the movable abutment part includes a bottom post 6, a spring 7, a guide post 9, and a movable body 8. One end of the bottom post 6 is connected to the support body 5. The spring 7 surrounds the outer periphery of the support body 5 and one end of the spring 7 is connected to the support body 5. The movable body 8 has a groove on the side facing the support body 5. The other end of the spring 7 is connected to the bottom wall of the groove. A guide groove is formed on the top surface of the bottom post 6. The guide post 9 is disposed on the bottom wall of the groove. The end of the guide post 9 facing the bottom post 6 extends into the guide groove. A connecting groove is formed on the top surface of the movable body 8 away from the support body 5, allowing the connecting protrusion to enter.

[0020] It should be noted that the movable body 8 is electrically connected to the power supply vehicle via a wire. When the connecting protrusion enters the connecting groove, the power supply vehicle is electrically connected to the power supply cabinet.

[0021] In the above embodiment, the drive separation part includes a rotating shaft 10, a traction rope 11, and a rotating handle 12. The bottom wall of the guide groove is provided with a traction groove for communicating with the receiving cavity. The rotating shaft 10 is disposed in the receiving cavity. One end of the traction rope 11 is connected to the guide post 9, and the other end of the traction rope 11 is connected to the rotating shaft 10. One end of the rotating handle 12 is connected to one end face of the rotating shaft 10, and the other end of the rotating handle 12 extends out of the receiving cavity and is outside the carrier 5. When the carrier 5 is completely inserted between the upper limit body 2 and the lower limit body 3, driving the rotating handle 12 can make the movable body 8 move toward the carrier 5 until the connecting protrusion disengages from the connecting groove.

[0022] In the above embodiment, the end of the movable body 8 that extends into the bayonet is set to an inclined state. When the movable body 8 is gradually inserted into the bayonet, the connecting protrusion squeezes the inclined surface of the movable body 8, so that the movable body 8 gradually approaches the carrier 5 until the connecting protrusion enters the connecting groove.

[0023] Working principle: When in use, insert the corresponding plug-in component into the corresponding socket. As the carrier 5 continues to enter, the inclined surface of the movable body 8 first contacts the connecting protrusion. The connecting protrusion squeezes the movable body 8, causing the movable body 8 to approach the carrier 5, until the connecting groove is directly opposite the connecting protrusion. The spring 7 rebounds, causing the connecting protrusion to enter the connecting groove and become unable to disengage, thus completing the plugging. When it is necessary to separate the plug-in component from the carrier component, rotate the rotating handle 12 to drive the rotating shaft 10 to rotate, causing the traction rope 11 to continuously wrap around the rotating shaft 10, which can pull the guide post 9 and compress the spring 7 until the connecting protrusion disengages from the connecting groove, allowing the plug-in component to be pulled out.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the content of the present utility model specification should be included within the protection scope of the present utility model.
