[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] The present invention provides a station access device for a virtual power plant, such as Figures 1 to 7 As shown, it includes a shell 1, a socket 2 connected to the interior of the shell 1 is equidistantly arranged on the front side of the shell 1, a plug board 3 is arranged inside the socket 2, and a limit groove 5 is symmetrically arranged on the inner wall of the socket 2. Limit strips matching the limit groove 5 are fixedly installed on both sides of the plug board 3. A mounting groove is arranged on the bottom wall of the socket 2, and a first spring 4 is fixedly installed in the mounting groove. The top of the first spring 4 is fixedly connected to the bottom of the plug board 3. Plugs 6 are equidistantly arranged on the plug board 3 from top to bottom. The plug 6 is a female connector on a male and female connector in the prior art. The shell 1 is provided with a Equipment element 22, equipment element 22 is an element inside the station-end access device of a virtual power plant in the prior art, the equipment element 22 is connected to the plug 6 via a transmission line, the transmission line is not shown in the figure, the transmission line does not affect the movement of the plug board 3, the top of the shell 1 is equidistantly provided with slide grooves corresponding to the plug board 3, a baffle 7 is slidably installed in the slide groove, the baffle 7 is in contact with the top of the plug board 3, the outer side of the shell 1 is symmetrically provided with heat dissipation ports 8, and the shell 1 is provided with a guide component for closing the heat dissipation port 8 and allowing the air inside the shell 1 to flow outward through the socket 2.

[0018] The male connector is connected to the plug 6. When repairing, the plug 6 needs to be separated from the male connector. At this time, the blocking bar 7 is pushed to move it in the direction away from the plugboard 3, so that the blocking bar 7 leaves the top of the plugboard 3. At this time, the compressed first spring 4 releases its force to push the plugboard 3 up, so that the wiring harness with the plug 6, the male connector and the end of the male connector rises, so that the male connector and the plug 6 are staggered with the male connectors and plugs 6 adjacent to the left and right, so that there are no other male connectors and plugs 6 on the left and right sides of the male connector that needs to be cancelled, so that there is space, and it is convenient to rotate the screws on the male connector to cancel the connection between the male connector and the plug 6. At this time, the heat dissipation port 8 can be closed in cooperation with the guide component while the plugboard 3 rises. Due to the rise of the plugboard 3, there is a gap between the bottom of the plugboard 3 and the bottom wall of the shell 1, and the guide component works to make The air in the shell 1 is blown outwards, and the air is blown outwards through the gap to form an airflow, which can prevent external dust from entering the shell 1 through the gap after the plug board 3 rises, so that no dust will enter the shell 1 during the process of canceling the connection between the male connector and the plug 6. Similarly, the replaced male connector is fixed to the plug 6. Since there are no other male connectors and plugs 6 on the left and right sides of the plug 6 on the rising plug board 3, it is also convenient to perform the connection operation. After the connection is completed, the plug board 3 can be pushed to descend, and the plug board 3 compresses the first spring 4 to deform it to generate a force. Finally, the plug board 3 is reset with the plug 6 and the male connector, and then the baffle 7 is reset so that one end of it is again located on the top of the plug board 3 and aligned to restrict it, so that the plug board 3 cannot move. At the same time, the guide component opens the heat dissipation port 8, and the replacement and docking between the male connector and the plug 6 is completed.

[0019] like Figures 3 to 5 As shown, the air guide assembly includes a cooling fan 23 fixedly mounted on the top wall of the outer shell 1, the cooling fan 23 corresponds to the position of the equipment component 22, the outer side of the outer shell 1 is symmetrically provided with transverse grooves, a closing plate 9 is provided at the heat dissipation port 8, a transverse plate 10 matching the transverse groove is fixedly mounted on the inner side of the closing plate 9, a second spring 11 is fixedly mounted on the side of the transverse plate 10 away from the plug plate 3, the other end of the second spring 11 is fixed to the inner wall of the transverse groove, the two closing plates 9 are fixedly connected by a connecting plate 12, and the connecting plate 12 abuts against one end of the baffle 7.

[0020] During normal use, the cooling fan 23 is turned on to dissipate heat for the device component 22. When the baffle 7 is pushed to move away from the plug board 3, the baffle 7 presses against the connecting plate 12 to move with the closing plate 9, thereby moving with the cross plate 10 to compress the second spring 11 to deform and generate a force. With the movement of the closing plate 9, the opened heat dissipation port 8 is closed, and the airflow generated by the cooling fan 23 flows outward through the gap between the plug board 3 and the housing 1, so that dust cannot enter the housing 1 through the gap, so that when replacing the public When the connector is connected, dust will not enter the housing 1. When the plugboard 3 rises and stops moving, the baffle 7 is released. Since the baffle 7 conflicts with the outer side of the plugboard 3, the second spring 11 cannot release its force. When the plugboard 3 is pressed down to reset, the end of the baffle 7 does not conflict with the outer side of the plugboard 3. At this time, the compressed second spring 11 releases its force to reset the cross plate 10, the closing plate 9 and the connecting plate 12, thereby pushing the baffle 7 to reset, so that the baffle 7 conflicts with the top of the plugboard 3, and the closing plate 9 is reset to open the heat dissipation port 8.

[0021] like Figure 5 to Figure 6 As shown, the front side of the plug board 3 is provided with openings corresponding to the plugs 6 at equal distances from top to bottom, and a support plate 13 is provided in the opening. The support plate 13 is arranged below the corresponding plug 6. No support plate 13 is arranged below the lowest plug 6, and a driving component is provided outside the support plate 13 for driving it to move toward the direction close to the plug 6.

[0022] As the plug board 3 rises, the male connector and the wiring harness at the end of the male connector will also rise. Since the end of the wiring harness away from the male connector is fixed to the rest of the equipment, the wiring harness will bend downward as the male connector rises, causing the upper wiring harness to conflict with the lower male connector, affecting the removal and replacement of the lower male connector. Therefore, when the plug board 3 rises, the driving assembly is used to push the support plate 13 toward the plug 6, so that the support plate 13 extends outward, and finally supports the wiring harness, so that the wiring harness is lifted up and separated from the male connector below, and will not hinder the removal of the lower male connector.

[0023] like Figures 5 to 7As shown, the driving assembly includes a carrier plate 14 fixedly mounted on the side of the plug board 3 away from the plug 6, the number of the carrier plates 14 corresponds to the number of the support plates 13 and is located below the corresponding support plate 13, a movable groove is provided on the top of the carrier plate 14, a movable plate 15 is slidably installed in the movable groove, the movable plate 15 is fixedly connected to the support plate 13, the side of the movable plate 15 close to the plug 6 is fixedly connected to the inner wall of the movable groove through a third spring 16, a vertical plate 17 is fixedly mounted on the bottom wall of the housing 1, a top plate 18 corresponding to the support plate 13 is equidistantly fixedly mounted on the side of the vertical plate 17 close to the plug board 3, an inclined surface 19 is provided on the side of the top plate 18 close to the plug board 3, and a vertical surface 20 connected to the inclined surface 19 is provided on the side of the top plate 18 except the topmost top plate 18 close to the plug board 3, and the carrier plate 14 is staggered with the top plate 18 and does not contact the top plate 18.

[0024] The plug board 3 rises, bringing with it the carrier board 14, the movable board 15, the third spring 16, and the support board 13. When the support board 13 rises, the end thereof away from the plug 6 contacts the inclined surface 19, causing it to be squeezed, thereby causing the support board 13 to move toward the plug 6 and extend outward. As the support board 13 moves, the movable board 15 moves accordingly, compressing the third spring 16 to deform it and generate a force. When the plug board 3 descends and resets, on the contrary, the third spring 16 continuously releases a force to drive the movable board 15 and the support board 13 to reset, causing the support board 13 to be retracted, so that the support board 13 will not block the inspection of the male connector and the plug 6.

[0025] like Figures 5 to 7 As shown, the length of the inclined surface 19 decreases from top to bottom.

[0026] When the support plate 13 moves along the inclined surface 19, due to the inconsistent length of the inclined surface 19, the lowest support plate 13 will first move to the vertical surface 20, so that the lowest support plate 13 stops extending outward, and then the support plate 13 moves along the vertical surface 20. Finally, when the plug-in board 3 stops, the uppermost support plate 13 extends the longest. The extension lengths of the multiple support plates 13 decrease from top to bottom, so that the upper and lower adjacent wire harnesses are supported at different distances, so that the upper and lower adjacent wire harnesses will not contact each other, making it easy to pull out the male connector.

[0027] like Figure 6 to Figure 7 As shown, a V-shaped groove 21 is provided on one side of the support plate 13 close to the plug 6 .

[0028] The V-shaped groove 21 is provided so that the supported wire harness can be centered, so that the wire harness will not deflect to one side of the support plate 13 and separate from the support plate 13 , thereby ensuring the supporting effect of the support plate 13 .

[0029] like Figure 5As shown, when the lowermost support plate 13 moves to contact with the vertical plane 20 , the lowermost support plate 13 can contact with the wiring harness of the connecting plug 6 to support the wiring harness.

[0030] This ensures that each support plate 13 can support the wire harness on the male connector.

[0031] The method for accessing the virtual power plant using the above-mentioned station-side access device comprises the following steps: S1. The male connector is connected to the plug 6. When inspecting, the plug 6 needs to be separated from the male connector. At this time, the stop bar 7 is pushed to move away from the plugboard 3, so that the stop bar 7 leaves the top of the plugboard 3. At this time, the compressed first spring 4 releases the force to push the plugboard 3 up, so that the wiring harness with the plug 6, the male connector and the end of the male connector rises, so that the male connector and the plug 6 are staggered with the male connectors and the plug 6 adjacent to the left and right, so that there are no other male connectors and the plug 6 on the left and right sides of the male connector that needs to be cancelled, so that there is space, and it is convenient to rotate the screws on the male connector to cancel the connection between the male connector and the plug 6; S2. When the plug board 3 rises, the heat dissipation port 8 can be closed in cooperation with the air guide component. Due to the rise of the plug board 3, there is a gap between the bottom of the plug board 3 and the bottom wall of the housing 1. The air guide component works to blow the air in the housing 1 outward. The air blows outward through the gap to form an airflow, which can prevent dust from entering the housing 1 through the gap after the plug board 3 rises, so that no dust will enter the housing 1 during the process of canceling the connection between the male connector and the plug 6. S3. Similarly, fix the replaced male connector to the plug 6. Since there are no other male connectors and plugs 6 on the left and right sides of the plug 6 on the raised plugboard 3, it is also convenient to perform the connection operation. After the connection is completed, the plugboard 3 can be pushed to descend. The plugboard 3 compresses the first spring 4 to deform it and generate a force. Finally, the plugboard 3 is reset with the plug 6 and the male connector. Then, the blocking bar 7 is reset so that one end of it is aligned at the top of the plugboard 3 again to restrict it, so that the plugboard 3 cannot move. At the same time, the guide component opens the heat dissipation port 8. At this point, the replacement and docking between the male connector and the plug 6 is completed.

[0032] Working principle: During normal use, the cooling fan 23 is turned on to dissipate heat for the equipment component 22, and the male connector is connected to the plug 6. During maintenance, the plug 6 needs to be separated from the male connector. At this time, the baffle 7 is pushed to move it away from the plugboard 3, so that the baffle 7 leaves the top of the plugboard 3. At this time, the compressed first spring 4 releases its force to push the plugboard 3 up, so that there is a gap between the plugboard 3 and the housing 1. The plugboard 3 rises with the plug 6, the male connector and the wiring harness at the end of the male connector, so that the male connector and the plug 6 are staggered with the male connectors and the plug 6 adjacent to the left and right, so that there are no other male connectors and plugs 6 on the left and right sides of the male connector that needs to be cancelled, so that there is space. At this time, it is convenient to rotate the screws on the male connector to cancel the connection between the male connector and the plug 6. When the baffle 7 is pushed to move it away from the plugboard 3, the baffle 7 presses against the connecting plate 12 to move it with the closing plate 9, thereby moving it with the cross plate 10 and compressing the second spring 11 to deform it and generate a force. With the movement of the closing plate 9, The opened heat dissipation port 8 is closed, and the airflow generated by the heat dissipation fan 23 flows outward through the gap between the plug board 3 and the shell 1, so that dust cannot enter the shell 1 through the gap, so that dust will not enter the shell 1 when the male connector is replaced. When the plug board 3 rises and stops moving, the baffle 7 is released at this time. Since the baffle 7 conflicts with the outer side of the plug board 3, the second spring 11 cannot release the force at this time. Similarly, the replaced male connector is fixed to the plug 6. Since there are no other male connectors and plugs 6 on the left and right sides of the plug 6 on the rising plug board 3, it is also convenient to perform the connection operation. After the connection is completed, the plug board 3 can be pushed to descend, and the plug board 3 compresses the first spring 4 to deform it and generate a force. When the plug board 3 is pressed down to reset, the end of the baffle 7 does not conflict with the outer side of the plug board 3. At this time, the compressed second spring 11 releases the force to reset the cross plate 10, the closing plate 9 and the connecting plate 12, thereby pushing the baffle 7 to reset, so that the baffle 7 conflicts with the top of the plug board 3, and the closing plate 9 is reset to open the heat dissipation port 8;As the plug board 3 rises, the male connector and the wiring harness at the end of the male connector will rise. Since the end of the wiring harness away from the male connector is fixed to the rest of the equipment, the wiring harness will bend downward as the male connector rises, causing the upper wiring harness to conflict with the lower male connector, affecting the removal and replacement of the lower male connector. Therefore, when the plug board 3 rises, the carrier plate 14, the movable plate 15, the third spring 16, and the support plate 13 are also raised. When the support plate 13 rises, the end of the support plate 13 away from the plug 6 conflicts with the inclined surface 19, causing it to be squeezed, thereby causing the support plate 13 to move toward the plug 6 and extend outward. As the support plate 13 moves, the movable plate 15 moves with it, compressing the third spring 16 to deform it and generate a force, thereby supporting the wiring harness, so that the wiring harness is lifted up and separated from the male connector below, which will not hinder the removal of the male connector below. When the support plate 13 moves along the inclined surface 19 When the plug board 3 stops, the uppermost support plate 13 will extend the longest due to the inconsistent length of the inclined surface 19, so that the lowermost support plate 13 stops extending outward, and then the support plate 13 moves along the vertical surface 20. Finally, when the plug board 3 stops, the uppermost support plate 13 extends the longest. The extension lengths of the multiple support plates 13 decrease from top to bottom, so that the upper and lower adjacent wire harnesses are supported at different distances, so that the upper and lower adjacent wire harnesses will not contact each other, making it easy to pull out the male connector. The setting of the V-shaped groove 21 can center the supported wire harness, so that the wire harness will not deflect to one side of the support plate 13 and leave the support plate 13, ensuring the support effect of the support plate 13. When the plug board 3 drops and resets, on the contrary, the third spring 16 continuously releases the force to drive the moving plate 15 and the support plate 13 to reset, so that the support plate 13 is retracted, so that the support plate 13 will not block the inspection of the male connector and the plug 6. ;

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.

5. The station-side access device for a virtual power plant according to claim 4, characterized in that: The length of the inclined surface (19) decreases from top to bottom.

6. The station-side access device for a virtual power plant according to claim 5, characterized in that: A V-shaped groove (21) is provided on one side of the support plate (13) close to the plug (6).

7. The station-side access device for a virtual power plant according to claim 6, characterized in that: When the lowermost support plate (13) moves to contact the vertical plane (20), the lowermost support plate (13) can contact the wiring harness of the connection plug (6) to support the wiring harness.

8. A method for accessing a virtual power plant using a station-side access device as claimed in claim 7, characterized in that: The steps include: S1, the male connector is connected to the plug (6). When the plug (6) is to be separated from the male connector during maintenance, the retaining bar (7) is pushed to move away from the plug board (3), so that the retaining bar (7) leaves the top of the plug board (3). At this time, the compressed first spring (4) releases its force to push the plug board (3) upward, so that the wiring harness with the plug (6), the male connector and the end of the male connector rises, so that the male connector and the plug (6) are staggered with the male connectors and the plugs (6) adjacent to the left and right, so that there are no other male connectors and the plugs (6) on the left and right sides of the male connector to be disconnected, so that there is space, so that it is convenient to rotate the screw on the male connector, so that the connection between the male connector and the plug (6) is disconnected; S2. When the plug board (3) rises, the heat dissipation port (8) can be closed in cooperation with the air guide component. Due to the rise of the plug board (3), a gap is formed between the bottom of the plug board (3) and the bottom wall of the housing (1). The air guide component works to blow the air in the housing (1) outwards. The air blows outwards through the gap to form an airflow, which can prevent dust from entering the housing (1) through the gap after the plug board (3) rises. In this way, when the connection between the male connector and the plug (6) is cancelled, no dust will enter the housing (1). S3. Similarly, the replaced male connector is fixed to the plug (6). Since there are no other male connectors and plugs (6) on the left and right sides of the plug (6) on the raised plug board (3), it is also easy to perform the connection operation. After the connection is completed, the plug board (3) can be pushed to descend. The plug board (3) compresses the first spring (4) to deform it and generate a force. Finally, the plug board (3) is reset with the plug (6) and the male connector. Then, the stop bar (7) is reset so that one end of it is aligned with the top of the plug board (3) again to restrict it, so that the plug board (3) cannot move. At the same time, the guide component opens the heat dissipation port (8). At this point, the replacement and docking between the male connector and the plug (6) is completed.
