Detailed implementation manners

[0027] Please refer to Figures 1-7 , the present invention provides a technical solution: an improved electrical connection device, including a fixed seat 1, three power cords 2 and three output wires 3. The fixed seat 1 is used to fix the three power cords 2 and the three output wires 3 in the power distribution cabinet; three connectors 4 are fixedly connected to the fixed seat 1, and the three connectors 4 are arranged in a circumferential array on the fixed seat 1; the connector 4 is located between the power cord 2 and the output wire 3, and both the power cord 2 and the output wire 3 are fixedly connected to the connector 4;

[0028] A connection mechanism is provided on the connector 4, and the connection mechanism is used to connect the other power cords 2 and the output wires 3 connected thereto after the power cord 2 connected thereto loses power;

[0029] A driving mechanism is provided on the fixed seat 1, and the driving mechanism is used to drive the connection mechanism that has lost power to operate;

[0030] The connector 4 is provided with a detection mechanism, which is used to automatically trigger the operation of the driving mechanism after detecting that the power supply line 2 connected to the connector 4 loses power;

[0031] During operation, the three power supply lines 2 are respectively connected to the three connectors 4, and then the three output wires 3 are respectively connected to the three connectors 4. At this time, the three power supply lines 2 are respectively connected to the three output wires 3, and the output wires 3 are used to supply power to various other devices; when one of the power supply lines 2 loses power for various reasons, in order not to delay the operation of the device, after the detection mechanism detects that the power supply line 2 loses power, it triggers the operation of the driving mechanism. The driving mechanism drives the connecting mechanism on the connector 4 connected to the power supply line 2 to operate, and the connecting mechanism quickly connects the connector 4 to the adjacent connector 4 with power. At this time, the normal power supply line 2 will distribute the power to this connector 4, and this connector 4 can ensure that the output wire 3 connected to it continues to supply power, thus avoiding the construction equipment from being in a long-term shutdown state due to power loss and effectively ensuring the efficiency of building construction.

[0032] As Figures 5-6 shown, as a further solution of the present invention, the connecting mechanism includes three first connecting wires 5 and three second connecting wires 6. The three first connecting wires 5 are respectively connected to the three wires in the output wire 3, and the three second connecting wires 6 are respectively connected to the three wires in the output wire 3; one end of the first connecting wire 5 far from the connector 4 is fixedly connected with a first brush 7, the surface of the first brush 7 is attached to a second brush 8, and a first contact 9 is fixedly connected to the second brush 8; one end of the second connecting wire 6 far from the connector 4 is fixedly connected with a second contact 10;

[0033] During operation, when the power supply line 2 connected to the connector 4 loses power, the three first contacts 9 connected to the connector 4 are driven to move. When the three first contacts 9 move to the positions where they are respectively in contact with the three second contacts 10 connected to another connector 4, the current on the normal power supply line 2 will flow into this connector 4 through the three second contacts 10 and the three first contacts 9, and the output wire 3 connected to this connector 4 can resume power supply (since the wires used in building construction are usually three-phase wires, there are three wires in both the power supply line 2 and the output wire 3).

[0034] As Figures 6-7As shown in the figure, as a further solution of the present invention, the driving mechanism includes three sliding grooves 11. The three sliding grooves 11 are formed in the fixed seat 1 and all three sliding grooves 11 are in a circular shape. The three sliding grooves 11 are concentrically distributed. The three sliding grooves 11 penetrate through the front surface of the fixed seat 1 near the position of the connecting head 4. Three first contacts 9 and three second contacts 10 are respectively located in the three sliding grooves 11. The first contact 9 is slidably connected to the sliding groove 11 and the second contact 10 is fixedly connected to the inner wall of the sliding groove 11. Three moving mechanisms are provided on the fixed seat 1. The moving mechanism is used to drive the three first contacts 9 at three positions inside the fixed seat 1 to move.

[0035] The moving mechanism includes a moving plate 12. The moving plate 12 is located at the front side of the fixed seat 1 and the moving plate 12 is fixedly connected to the three first contacts 9 connected to the connecting head 4. Three fixing frames 13 are fixedly connected to the fixed seat 1. The three fixing frames 13 are circumferentially arranged on the fixed seat 1. A threaded rod 14 is rotatably arranged in the fixing frame 13. A first push block 15 is threadedly connected to the threaded rod 14. A second push block 16 is arranged in front of the first push block 15. Both the first push block 15 and the second push block 16 are slidably connected to the fixing frame 13. A first connecting block 17 is rotatably connected to the second push block 16. A second connecting block 18 is rotatably connected to the moving plate 12. A first connecting rod 19 is arranged between the first connecting block 17 and the second connecting block 18. Both ends of the first connecting rod 19 are rotatably connected to the first connecting block 17 and the second connecting block 18 respectively.

[0036] A first spring 20 is fixedly connected to the front end position of the second push block 16. The front end of the first spring 20 is fixedly connected to the fixing frame 13. The threaded rod 14 has self-locking property.

[0037] Three partition plates 21 are provided on the fixed seat 1. The three partition plates 21 are circumferentially arranged on the fixed seat 1 and each partition plate 21 is arranged between two adjacent connecting heads 4. The partition plate 21 cuts off the three sliding grooves 11 and is located between the three first contacts 9 and the three second contacts 10 connected to the two connecting heads 4. The partition plate 21 is fixedly connected to the first push block 15.

[0038] During operation, when it is necessary to drive the three first contacts 9 that have lost power, the threaded rod 14 corresponding to these three first contacts 9 is rotated. When the threaded rod 14 rotates, it drives the first push block 15 to move forward. When the first push block 15 moves forward, it will drive the partition plate 21 to move forward. When the first push block 15 moves to a position where it fits with the second push block 16, at this time, the partition plate 21 no longer blocks the three first contacts 9 and the three second contacts 10. As the threaded rod 14 continues to rotate, the first push block 15 pushes the second push block 16 to move forward. At this time, the second push block 16 pulls the moving plate 12 to start moving towards the partition plate 21 through the first connecting rod 19. When the moving plate 12 moves, it will drive the three first contacts 9 connected to it to move. When the three first contacts 9 move to a position where they contact the three second contacts 10 on another connector 4, at this time, the rotation of the threaded rod 14 is stopped. Since the threaded rod 14 has self-locking property, the three first contacts 9 will stably remain in a state of fitting with the three second contacts 10. When the power supply line 2 resumes power supply, the threaded rod 14 is driven to rotate in the reverse direction. Under the action of the first spring 20, the moving plate 12 drives the three first contacts 9 to reset first. After the three first contacts 9 are reset, the partition plate 21 starts to reset. The partition plate 21 can play a role in completely separating the three first contacts 9 and the three second contacts 10, which can further improve the safety of the overall device.

[0039] As Figures 5-7 shown, as a further solution of the present invention, the detection mechanism includes a fixing plate 22 and a sliding rod 23. The fixing plate 22 is fixedly connected to the fixed seat 1 and the sliding rod 23 is fixedly connected to the fixing plate 22. A first permanent magnet 24 is fixedly connected to the fixing plate 22. The surface of the first permanent magnet 24 away from the fixing plate 22 is attached to an electromagnet 25. The surface of the electromagnet 25 away from the first permanent magnet 24 is attached to a second permanent magnet 26. A third brush 27 is connected to the connector 4. A fourth brush 28 is attached to the third brush 27. The fourth brush 28 is connected to the electromagnet 25. Both the electromagnet 25 and the second permanent magnet 26 are slidably connected to the sliding rod 23. A rack 29 is fixedly connected to the second permanent magnet 26. A first gear 30 is engaged with the rack 29. A second gear 31 is fixedly connected to the rear end of the first gear 30. A third gear 32 is engaged with the second gear 31. Both the second gear 31 and the third gear 32 are rotatably connected to the fixing frame 13 and the third gear 32 is fixedly connected to the threaded rod 14. The diameters of both the first gear 30 and the third gear 32 are smaller than that of the second gear 31. A second spring 33 is sleeved on the sliding rod 23. One end of the second spring 33 is fixedly connected to the rack 29 and the other end is fixedly connected to the sliding rod 23.

[0040] There are two second connecting rods 34 at the middle position of the electromagnet 25. The two second connecting rods 34 are cross-distributed, and the cross positions of the two second connecting rods 34 are both rotatably connected to the electromagnet 25. Both ends of the second connecting rod 34 are rotatably connected with a third connecting rod 35, and the third connecting rod 35 on one second connecting rod 34 is rotatably connected to the third connecting rod 35 on the other second connecting rod 34. The parts where the two third connecting rods 35 are connected to each other at two places are respectively rotatably connected to the first permanent magnet 24 and the second permanent magnet 26.

[0041] During operation, when the power supply line 2 is normally powered, the connector 4 can supply power to the electromagnet 25 through the third brush 27 and the fourth brush 28, and the electromagnet 25 firmly adsorbs the first permanent magnet 24 and the second permanent magnet 26. When the power supply line 2 loses power, at this time the electromagnet 25 loses magnetism. Under the action of the second spring 33, the rack 29 drives the second permanent magnet 26 to start moving in a direction away from the electromagnet 25. When the rack 29 moves, it will drive the first gear 30 to rotate. The first gear 30 drives the second gear 31 to rotate, and the second gear 31 will drive the third gear 32 to rotate. The third gear 32 drives the threaded rod 14 to rotate. Since the diameters of the first gear 30 and the third gear 32 are smaller than the diameter of the second gear 31, when the first gear 30 rotates one circle, the third gear 32 can rotate multiple circles, so as to drive the threaded rod 14 to rotate multiple circles, ensuring that the first push block 15 can move a sufficient distance.

[0042] During the movement of the second permanent magnet 26, the electromagnet 25 can be driven to move through the two second connecting rods 34 and the four third connecting rods 35, and the electromagnet 25 can always be in the position between the first permanent magnet 24 and the second permanent magnet 26. The electromagnet 25 can maintain the same magnitude of magnetic force on the first permanent magnet 24 and the second permanent magnet 26. In addition, while ensuring the magnetic force intensity of the electromagnet 25 on the first permanent magnet 24, the moving distance of the rack 29 can be effectively increased.

[0043] When the power supply line 2 resumes power supply, the electromagnet 25 resumes magnetism and starts to adsorb the first permanent magnet 24 and the second permanent magnet 26 at the same time. The electromagnet 25 and the second permanent magnet 26 move in the direction close to the first permanent magnet 24 at the same time.
