Description

Technical Field

[0001] The present invention relates to the technical field of power systems. More specifically, the present invention relates to a fault detection device and method for a power system data center. Background Art

[0002] The power data center is an integrated platform that can uniformly manage and analyze various data in the power industry. It has functions such as data acquisition, data storage, data processing, and data analysis. Through the power data center, power enterprises can monitor the operation status of the power grid in real time, predict power load demand, optimize power dispatching, etc., which not only improves the operation efficiency of power enterprises but also enhances the reliability and security of power services.

[0003] The application of electrical connectors in the data center mainly focuses on the hardware infrastructure level, providing physical support for the stable operation, efficient data transmission, and modular expansion of the data center. If a fault occurs in the electrical connector, it may cause the disconnection of servers, storage devices, or network devices from the data center, and even lead to data loss or hardware damage.

[0004] However, when a fault occurs in the data center and troubleshooting, it is difficult to directly determine whether the fault occurs at the electrical connector. Therefore, it is necessary to detect the electrical connector. Currently, when detecting an electrical connector with a cable, the electrical connector is connected to a detection plug, and then powered on for detection to observe whether the data transmission is normal. However, since some electrical connectors have a large number of pins, due to the frequent use of the detection plug, the detection plug itself cannot determine whether it is good or bad. Therefore, a disk with contacts is currently used. During detection, the pins of the electrical adapter are pressed on the contacts, and then electrical detection is performed.

[0005] When the pins of the electrical connector are in use, the side wall contacts the metal sheet inside the female head. When using the disk for detection, the tip part of the pin contacts the disk. If the tip part of the pin is oxidized, it will cause inaccurate detection results and may detect a good electrical connector as a damaged one. Summary of the Invention

[0006] A fault detection device and method for a power system data center provided by the present invention aims to solve the problem that when detecting whether a fault occurs in an electrical connector with a cable, if the tip part of the pin is oxidized, it will cause inaccurate detection results.

The supporting block is used to lift the supporting rod upward.

[0011] In a preferred embodiment, a movable rod is movably inserted into one end of the U-shaped cylinder where the detection disk is located.

A second spring is sleeved on the outside of the movable rod, and the two ends of the second spring are respectively pressed against the lower end of the movable rod and the upper end of the U-shaped cylinder. A first spring is arranged inside the detection disk, and the two ends of the first spring are respectively pressed against the upper end of the movable rod and the detection disk.

[0012] In a preferred embodiment, the clamp includes a main frame fixedly connected to the bottom of the inner cylinder. A lead screw is rotatably installed on the main frame. A slider is threadedly connected to the lead screw and slidably connected to the main frame. A clamping plate is fixedly installed on the slider for clamping the electrical connector on the main frame. The supporting block is connected to the main frame.

[0013] In a preferred embodiment, the upper surface of the detection disk is lower than the upper surface of the grinding plate. A vertical rod is installed on the detection host, and the grinding plate is fixedly connected to the upper end of the vertical rod.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Refer to the attached drawings of the specification Figures 1 - 9, A fault detection device for a power system data center, including a detection host 1. A bracket 11 is installed on the detection host 1, and a driving component 2 is installed on the bracket 11. The output end of the driving component 2 is installed with a fixture 3. The fixture 3 is used to clamp the electrical connector 7 and make the pins 71 of the electrical connector 7 face downward; a friction area and a detection area are arranged below the driving component 2. A grinding plate 4 is arranged in the friction area, and a detection component 5 is arranged in the detection area. The detection component 5 includes a detection disc 51. The detection disc 51 is electrically connected to the detection host 1, and contact points 511 corresponding to the pins 71 one by one are arranged on the upper surface of the detection disc 51; the driving component 2 is used to drive the electrical connector 7 to move in the friction area and the detection area. Thus, when in the friction area, the pins 71 generate friction with the upper surface of the grinding plate 4, and when in the detection area, the pins 71 contact the contact points 511.

[0036] In this embodiment, as Figures 3 - 5 shown, the driving component 2 includes a fixed cylinder 21. The fixed cylinder 21 is fixedly connected to the bracket 11. A rectangular groove 211 composed of an upper horizontal groove 2111, a left vertical groove 2112, a lower horizontal groove 2113, and a right vertical groove 2114 is arranged on the side wall of the fixed cylinder 21. An inner cylinder 22 is movably arranged inside the fixed cylinder 21. A fixed shaft 23 is fixedly connected to the inner cylinder 22. The driving component 2 further includes a power component 24. The power component 24 is used to drive one end of the fixed shaft 23 to slide inside the rectangular groove 211. The fixture 3 is installed at the bottom of the inner cylinder 22.

[0037] Furthermore, the power component 24 includes a main shaft 241. The main shaft 241 is rotatably connected to the fixed cylinder 21. Two parallel holding rods 242 are fixedly connected to one end of the main shaft 241. One end of the fixed shaft 23 is movably arranged between the two holding rods 242. A motor 243 is fixedly installed on the fixed cylinder 21. The output end of the motor 243 is fixedly connected to the main shaft 241.

[0038] It should be noted that the rectangular groove 211 is successively composed of an upper horizontal groove 2111, a left vertical groove 2112, a lower horizontal groove 2113, and a right vertical groove 2114. One end of the fixed shaft 23 is inserted into the inside of the rectangular groove 211. Thus, the fixed shaft 23 can move cyclically inside the rectangular groove 211. The motor 243 can drive the main shaft 241 to rotate. The two holding rods 242 clamp the fixed shaft 23 in the middle. When the two holding rods 242 rotate together with the main shaft 241, the two holding rods 242 can drive the fixed shaft 23 to move, so that one end of the fixed shaft 23 moves inside the rectangular groove 211. When the fixed shaft 23 moves in the upper horizontal groove 2111 or the lower horizontal groove 2113, the fixture 3 swings. When the fixed shaft 23 moves in the left vertical groove 2112 or the right vertical groove 2114, the fixed shaft 23 moves downward or upward.

[0039] In this embodiment, as Figure 8As shown in the figure, the fixture 3 includes a main frame 31, the main frame 31 is fixedly connected to the bottom of the inner cylinder 22, a lead screw 34 is rotatably installed on the main frame 31, a slider 32 is threadedly connected to the lead screw 34, the slider 32 is slidably connected to the main frame 31, a clamping plate 33 is fixedly installed on the slider 32, the clamping plate 33 is used to clamp the electrical connector 7 on the main frame 31, and a supporting block 35 is connected to the main frame 31.

[0040] It should be noted that the electrical connector 7 is placed between the main frame 31 and the clamping plate 33, and then the lead screw 34 is rotated. The lead screw 34 drives the clamping plate 33 to move towards the main frame 31, so that the grinding plate 4 can be clamped.

[0041] In this embodiment, as Figures 1 - 2 、 Figures 6 - 7 shown, the detection assembly 5 further includes an upright frame 50, the upright frame 50 is fixedly installed on the detection host 1, a U-shaped cylinder 52 is vertically sleeved on the upright frame 50, a detection disc 51 is arranged at the top of one end of the U-shaped cylinder 52, the upper end of the upright frame 50 is fixedly connected with a pressure rod 54, the lower end of the pressure rod 54 is movably inserted into the interior of the other end of the U-shaped cylinder 52, a plurality of balls 53 are arranged inside the U-shaped cylinder 52, the U-shaped cylinder 52 is fixedly connected with a support rod 55, and the fixture 3 is fixedly connected with a support block 35, and the support block 35 is used to lift the support rod 55 upward.

[0042] Furthermore, a movable rod 56 is movably inserted into one end of the U-shaped cylinder 52 where the detection disc 51 is located, the detection disc 51 is vertically sleeved on the movable rod 56, a second spring 58 is sleeved on the outer side of the movable rod 56, and both ends of the second spring 58 are respectively pressed against the lower end of the movable rod 56 and the upper end of the U-shaped cylinder 52. A first spring 57 is arranged inside the detection disc 51, and both ends of the first spring 57 are respectively pressed against the upper end of the movable rod 56 and the detection disc 51.

[0043] It should be noted that the first spring 57 is used for the detection disc 51 to reset upward, and the second spring 58 is used for the movable rod 56 to reset downward.

[0044] Furthermore, as Figure 1 and Figure 2 shown, the upper surface of the detection disc 51 is lower than the upper surface of the grinding plate 4, a vertical rod 41 is installed on the detection host 1, and the grinding plate 4 is fixedly connected to the upper end of the vertical rod 41.

[0045] In this embodiment, the implementation method is as follows: First, use the fixture 3 to clamp the electrical connector 7. When clamping, place the electrical connector 7 between the main frame 31 and the clamping plate 33, and then rotate the lead screw 34. The lead screw 34 drives the clamping plate 33 to move towards the main frame 31, so that the grinding plate 4 can be clamped, and then connect the other end of the fixture 3 with the cable to the detection host 1. The initial state is as Figures 1 - 5As shown, the fixed shaft 23 is located inside the upper horizontal groove 2111, and then the inner cylinder 22 is driven by the power component 24 to move. During the movement, the fixed shaft 23 moves counterclockwise in the Figure 3 direction. Specifically, the motor 243 drives the main shaft 241 to rotate, the main shaft 241 drives the two holding rods 242 to rotate, and the two power components 24 drive the fixed shaft 23 to slide inside the rectangular groove 211. In addition, the fixed shaft 23 also drives the inner cylinder 22 to move.

[0046] First, the fixed shaft 23 moves from the upper horizontal groove 2111 to the left vertical groove 2112, and at this time, the fixture 3 drives the electrical connector 7 to swing; then the fixed shaft 23 moves downward from the left vertical groove 2112 to the lower horizontal groove 2113. At this time, the fixture 3 drives the electrical connector 7 to move downward. When the fixed shaft 23 moves to the bottom end of the left vertical groove 2112, the pin 71 at the bottom of the electrical connector 7 contacts the upper surface of the grinding plate 4; secondly, the fixed shaft 23 moves to the right from the lower horizontal groove 2113. At this time, the fixture 3 drives the electrical connector 7 to swing. At this time, the end of the pin 71 generates friction on the surface of the grinding plate 4, so that the oxide layer at the end of the pin 71 can be removed. In addition, during the movement of the fixed shaft 23 in the lower horizontal groove 2113, the motor 243 can be controlled to rotate forward and reverse repeatedly, so that the fixed shaft 23 can reciprocate in the lower horizontal groove 2113, that is, the electrical connector 7 swings reciprocally. In this way, the stroke of the pin 71 rubbing on the surface of the grinding plate 4 can be longer, and the oxide layer can be removed more thoroughly; furthermore, the fixed shaft 23 moves to the rightmost end of the lower horizontal groove 2113 and moves upward along the right vertical groove 2114. When the fixed shaft 23 moves to the rightmost end of the lower horizontal groove 2113, the support block 35 moves to the position directly below the upper end of the support rod 55. The support rod 55 is in the shape of the number "7". At this time, when the fixed shaft 23 moves upward, the support rod 55 can be pulled upward through the support block 35. The support rod 55 drives the U-shaped cylinder 52 and the detection disk 51 to move upward, and the pressure rod 54 remains stationary. During the upward movement of the U-shaped cylinder 52, the pressure rod 54 will press down the ball 53, so that the ball 53 at the other end of the U-shaped cylinder 52 pushes the movable rod 56 upward, and the movable rod 56 pushes the detection disk 51 upward. That is to say, when the fixture 3 moves upward, the detection disk 51 also moves upward. However, due to the push of the ball 53, the upward movement speed of the detection disk 51 is faster than the movement speed of the fixture 3. Therefore, during the upward movement of the fixed shaft 23 along the right vertical groove 2114, the detection disk 51 will move upward quickly so that the contact point 511 contacts the corresponding pin 71 to achieve the purpose of electrical connection.

[0047] Finally, the detection host 1 transmits data through the fixture 3 with a cable. If the data transmission is abnormal, the fixture 3 is faulty; otherwise, it is qualified.

[0048] The above technical solution sets the driving component 2, the grinding plate 4 and the detection component 5. When detecting the faults of the electrical connector 7, the end of the pin 71 is ground first, so as to remove the oxide layer at the end and prevent the inaccurate detection results caused by the normal pin 71 not being conductive during detection. Moreover, the above technical solution makes the upper surface of the detection disc 51 lower than the upper surface of the grinding plate 4, and when the electrical connector 7 moves to the detection area and moves upward, the moving speed of the detection disc 51 is greater than that of the electrical connector 7, so that the contact 511 moves upward to establish a connection with the pin 71. The purpose is to prevent a small gap between the pin 71 and the contact 511 when the pin 71 directly contacts the contact 511 when moving to the detection area, resulting in non-conduction.

[0049] Referring to the attached drawings of the specification Figures 1 - 2 , a cage 6 is rotatably connected to the bracket 11 through a torsion spring. Through holes 61 are formed on the surface of the cage 6, and the through holes 61 correspond to the pins 71 one by one. When the pins 71 are inserted downward into the through holes 61, the lower ends of the pins 71 extend out of the lower surface of the cage 6.

[0050] It should be noted that in Figure 1 and Figure 2 directions, the torsion spring is used to reset the cage 6 to the left. When the fixed shaft 23 moves downward from the left vertical groove 2112, the pins 71 are inserted into the interior of the through holes 61. The purpose is to protect the pins 71 and prevent the pins 71 from being bent due to their excessive length when they rub against the grinding plate 4. When the fixed shaft 23 moves upward from the right vertical groove 2114, the pins 71 are pulled out of the through holes 61 again, and then the cage 6 is reset under the action of the torsion spring.

[0051] Referring to the attached drawings of the specification Figures 1 - 2 , a cleaning cotton 42 is fixedly connected to one end of the grinding plate 4 close to the detection disc 51, and the upper surface of the cleaning cotton 42 is higher than the upper surface of the grinding plate 4.

[0052] It should be noted that after the pins 71 rub against the grinding plate 4, the pins 71 contact the cleaning cotton 42, so as to remove the metal debris at the ends of the pins 71 and prevent unnecessary influence during detection.

[0053] Referring to the attached drawings of the specification Figures 1 - 9 , a fault detection method for the power system data center uses the above-mentioned fault detection device for the power system data center, including the following steps:

[0054] Step 1: Use the fixture 3 to clamp the electrical connector 7, make the pins 71 face downward, and connect the other end of the fixture 3 with the cable to the detection host 1;

[0055] Step 2: Drive the electrical connector 7 to move in the friction area through the driving component 2, so that the end of the pin 71 generates friction with the surface of the grinding plate 4, thereby grinding the end of the pin 71;

[0056] Step 3: Drive the electrical connector 7 to move in the detection area through the driving component 2, so that the pins 71 are in one-to-one contact with the contact points 511;

[0057] Step 4: Transmit data through the fixture 3 with cables. If the data transmission is abnormal, the fixture 3 is faulty; otherwise, it is qualified.

[0058] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
