They are responsible for meeting human electricity demand and maintaining the rapid development of social economy. The operating status of power plant equipment is related to the overall operating efficiency and economic benefits of the power plant. However, since power plants need to continuously and massively supply electricity to people's production and life, in the actual operation of power plants, some operating failures of electrical equipment are inevitable, which will reduce the production efficiency and operating stability of power plants. In the patent with application number 202310355877.1, "a power plant equipment operation fault diagnosis device is disclosed, including an electric control cabinet and a diagnostic device, and the diagnostic device is installed at the bottom of the electric control cabinet; The diagnostic device comprises a diagnostic box and a rotating door. The top of the diagnostic box is fixedly connected to the electric control cabinet. The front side of the diagnostic box is rotatably connected to the rotating door. A handle is installed on the front side of the rotating door. A multimeter is fixedly connected to the inside of the diagnostic box. The bottom of the multimeter is fixedly connected to a fixed frame. The top of the fixed frame is fixedly connected to evenly distributed connection components. In the present invention, by setting a diagnostic device at the bottom of the electric control cabinet, once a fault occurs in the power plant, maintenance personnel rush to the fault area and open the rotating door through the handle. When diagnosing the fault inside the electric control cabinet, the multimeter is adjusted to the corresponding gear and the connection component at the corresponding position is pushed to connect with the second pair of connectors above. Fault diagnosis can be performed, which is very convenient.

[0003] Nevertheless, when diagnosing power equipment, it is inevitable that maintenance personnel need to troubleshoot all aspects of the equipment. This requires not only a convenient and efficient diagnostic method, but also a wide range of applicability. In addition, power plant equipment is located in different locations, and it is difficult for workers at higher levels of power equipment to detect faults.

[0018] A convenient and mobile method for diagnosing power plant equipment operation faults comprises the following steps:

[0019] S1. Before use, move the entire device to the designated position and then extend the universal wheel to the bottom of the base and hide it, so that the base falls on the ground. Since the first motor is installed inside the rotating seat, the first motor drives the first rotating shaft to rotate. Since the bottom ends of both sides of the first rotating plate are fixedly connected with fixed blocks, and a retractable first connecting rod is fixedly connected between the fixed block and the first rotating shaft, the rotation of the first rotating shaft drives the first connecting rod to rotate, so that the first rotating plate rotates to the left side of the base and is located at the upper end of the first groove. The second rotating plate rotates to the right side of the base and is located at the upper end of the second groove in the same way as the first rotating plate.

[0020] S2, start the electric telescopic rod to extend the two moving plates at both sides so that the shaft groove is located outside the base. Since the outer side of the fixed block is rotatably connected to the rotating block, the outer wall of the rotating block is fixedly connected to the second connecting rod, and the connecting shaft is connected between the front and rear second connecting rods. At this time, the connecting shaft follows the rotation of the first rotating plate and falls into the shaft groove at the top of the moving plate. Then start the electric telescopic rod again to extend the two moving plates at both sides. At this time, the connecting shaft is stuck in the shaft groove, and the connecting shaft moves in the direction away from the base along the extension of the moving plate, so that the first rotating plate above the first groove moves vertically downward and is embedded in the first groove. The second rotating plate above the second groove is similarly embedded in the second groove. At this time, the screw rod is in a vertical state, and the screw rod does not contact the upper surface of the mounting plate connected to the lifting platform.

[0021] S3. Open the door of the fault diagnosis box, and insert the diagnostic data line into the fault detection interface to upload the fault diagnosed by the electrical equipment to the host after analysis. If the height of the electrical equipment to be diagnosed is too high for the worker to detect the internal fault, he can stand on the lifting platform and start the drive motor. The drive motor drives the moving shaft to rotate. Since the moving shaft is fixedly connected to the screw rod, the screw rod is located in the groove, and a fixed plate is fixedly connected in the groove. The screw rod is threadedly connected to the fixed plate. Therefore, when the screw rod rotates, it will move downward under the action of the fixed plate, and at the same time drive the sliding frame connected to the sliding rail to move toward the fixed plate. When the screw rod moves to no longer contact the fixed plate, the moving shaft is located in the first thread groove of the fixed plate and does not contact the fixed plate. At this time, the screw rod is in contact with the mounting plate and is threadedly connected in the second thread groove. Continue to rotate the screw rod until the bottom of the sliding frame abuts against the upper surface of the fixed plate. At this time, when the screw rod can no longer move downward, the lifting platform starts to move upward, and adjusts the drive motor according to the height. When descending, the screw rod rotates in the opposite direction.

[0022] S4. When the worker needs the corresponding tool for diagnosis, he puts the tool in the placement frame. Since protective plates are installed on the front and rear sides of the lifting platform, a second motor connected to the end of the second rotating shaft is installed on the protective plate on the front side of the lifting platform. The second rotating shaft is set in the middle of the transmission main gear. Therefore, the transmission main gear rises with the rise of the lifting platform. The rotation of the second rotating shaft drives the transmission main gear to rotate, thereby driving the crawler and the transmission gear to rotate, and then the placement frame moves to deliver the tool to the hands of the worker standing on the high side of the lifting platform.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention realizes the rotation of the first rotating plate and the second rotating plate through a rotating mechanism, thereby forming a vertical state with the base, and realizes the lifting and moving of the lifting platform through the cooperation of the lifting mechanism. It can perform fault diagnosis on electrical equipment at high places according to actual needs, which is convenient for workers to operate. When the device is not used, the first rotating plate and the second rotating plate are closed, and the volume of the entire device becomes smaller. The universal wheels installed on the base are convenient for movement and have a wide range of uses. A fault detection interface is set on the lifting platform for plugging in data cables to obtain diagnostic data of electrical equipment. Protective plates are set on the front and rear sides of the lifting platform, and the first and second rotating plates are shielded on both sides to improve the safety factor of workers standing on the lifting platform. The storage slot can be used to place diagnostic tools and data cables.

[0025] 2. The present invention places the tool into the placement frame through the transmission mechanism and transmits it upward from the bottom along the crawler belt, which is convenient for providing workers with tools that are needed but inconvenient to get, and improves the efficiency of fault diagnosis. The fixed plate in the lifting mechanism is arranged so that the speed of rotation of the screw rod and the fixed plate thread and the speed of rotation of the screw rod and the mounting plate thread are matched, and plays a guiding role, which is convenient for the screw rod to be accurately connected to the mounting plate. The opening and closing mechanism is arranged so that the two connecting shafts can move smoothly to both sides, and are supported by the first connecting rod that is retractable and provided with a shock-absorbing spring, which plays a supporting role on both sides of the first connecting plate and the second connecting plate respectively, thereby improving the stability of the device.

The third rotating shaft 1206 is arranged in the middle of the transmission gear 1202. The guide rail 1207 is horizontally installed on the front side of the base 1 by bolts. The rear end of the third rotating shaft 1206 is installed on the movable seat of the guide rail 1207 by bolts. Universal wheels are movably installed on both sides of the front end and the rear end of the bottom of the base 1 through a telescopic mechanism to drive the base 1 to move.

[0056] A convenient and mobile method for diagnosing power plant equipment operation faults comprises the following steps:

[0057] S1. Before use, move the entire device to the designated position and then retract the universal wheel to the bottom of the base 1 to hide it, so that the base 1 falls to the ground. Since the rotating seat 703 is equipped with a first motor, the first motor drives the first rotating shaft 704 to rotate. Since the bottom ends of both sides of the first rotating plate 701 are fixedly connected with fixed blocks 705, and a retractable first connecting rod 706 is fixedly connected between the fixed block 705 and the first rotating shaft 704, the rotation of the first rotating shaft 704 drives the first connecting rod 706 to rotate, so that the first rotating plate 701 rotates to the left side of the base 1 and is located at the upper end of the first groove 14. The second rotating plate 702 is the same as the first rotating plate 701, so that the second rotating plate 702 rotates to the right side of the base 1 and is located at the upper end of the second groove 15;

[0058] S2, start the electric telescopic rod 902 to extend the two side moving plates 901 to the two sides so that the shaft groove 22 is located outside the base 1, because the outer side of the fixed block 705 is rotatably connected to the rotating block 707, the outer wall of the rotating block 707 is fixedly connected to the second connecting rod 708, and the connecting shaft 21 is connected between the second connecting rods 708 on the front and rear sides. At this time, the connecting shaft 21 falls into the shaft groove 22 at the top of the moving plate 901 under the action of gravity along the rotation of the first rotating plate 701, and then the electric telescopic rod 902 is started again, so that The movable plates 901 on both sides extend to both sides, and at this time, the connecting shaft 21 is stuck in the shaft groove 22. The connecting shaft 21 moves along the extension of the movable plate 901 in the direction away from the base 1, so that the first rotating plate 701 located above the first joint groove 14 moves vertically downward to be embedded in the first joint groove 14, and the second rotating plate 702 located above the second joint groove 15 is similarly embedded in the second joint groove 15. At this time, the screw rod 802 is in a vertical state, and the screw rod 802 does not contact the upper surface of the mounting plate 801 connected to the lifting platform 3;

[0059] S3. Open the door of the fault diagnosis box 4, insert the diagnostic data line into the fault detection interface 6, and upload the fault diagnosed by the electrical equipment to the host after analysis. If the height of the electrical equipment to be diagnosed is too high for the worker to detect the internal fault, he can stand on the lifting platform 3 and start the drive motor 807. The drive motor 807 drives the moving shaft 806 to rotate. Since the moving shaft 806 is fixedly connected to the screw rod 802, the screw rod 802 is located in the groove 10, and the fixing plate 803 is fixedly connected in the groove 10, and the screw rod 802 is threadedly connected to the fixing plate 803, so when the screw rod 802 rotates, it will move downward under the action of the fixing plate 803. , and at the same time drives the slide frame 805 slidably connected to the slide rail 804 to move toward the fixed plate 803. When the screw rod 802 moves to no longer contact the fixed plate 803, the moving shaft 806 is located in the first thread groove of the fixed plate 803 and no longer contacts the fixed plate 803. At this time, the screw rod 802 contacts the mounting plate 801 and is threadedly connected in the second thread groove 19. The screw rod 802 continues to rotate until the bottom of the slide frame 805 abuts against the upper surface of the fixed plate 803. At this time, when the screw rod 802 can no longer move downward, the lifting platform 3 starts to move upward, and the driving motor 807 is adjusted automatically according to the height. When descending, the screw rod 802 is rotated in the opposite direction.

[0060] S4. When the worker needs the corresponding tool during diagnosis, the tool is placed in the placement frame 1204. Since the front and rear sides of the lifting platform 3 are installed with protective plates 13, a second motor connected to the end of the second rotating shaft 1205 is installed on the protective plate 13 located on the front side of the lifting platform 3. The second rotating shaft 1205 is set in the middle of the transmission main gear 1201. Therefore, the transmission main gear 1201 rises with the rise of the lifting platform 3. The rotation of the second rotating shaft 1205 drives the transmission main gear 1201 to rotate, thereby driving the crawler 1203 and the transmission slave gear 1202 to rotate, and then the placement frame 1204 moves to deliver the tool to the worker standing on the high side of the lifting platform.

Before use, move the entire device to the designated position and then extend the universal wheel to the bottom end of the base and hide it, so that the base falls on the ground. Since the first motor is installed inside the rotating seat, the first motor drives the first rotating shaft to rotate. Since both sides of one end of the first rotating plate are fixedly connected with fixed blocks, and a retractable first connecting rod is fixedly connected between the fixed block and the first rotating shaft, the rotation of the first rotating shaft drives the first connecting rod to rotate, so that the first rotating plate rotates around the rotating seat to the top of the first joint groove, and the second rotating plate rotates to the top of the second joint groove in the same way as the first rotating plate; S2, start the electric telescopic rod to extend the two moving plates on both sides outward and extend to the outside of the base through the shaft groove. Since the outer side of the fixed block is rotatably connected with the rotating block, the outer wall of the rotating block is fixedly connected with the second connecting rod, and a connecting shaft is connected between the second connecting rods located on the first rotating plate or the second rotating plate on both sides. At this time, the connecting shaft falls into the shaft groove at the top of the moving plate under the action of gravity along the rotation of the first rotating plate, and then the electric telescopic rod is started again to extend the moving plates on both sides of the fixed seat outward. At this time, the connecting shaft is stuck in the shaft groove, and the connecting shaft moves in the direction away from the base along the extension of the moving plate, so that the first rotating plate located above the first groove moves vertically downward and is embedded in the first groove, and the second rotating plate located above the second groove is similarly embedded in the second groove. At this time, the screw rod is in a vertical state, and the screw rod does not contact the upper surface of the mounting plate connected to the lifting platform; S3. Open the door of the fault diagnosis box, and insert the diagnostic data line into the fault detection interface to upload the fault diagnosed by the electrical equipment to the host after analysis. If the height of the electrical equipment to be diagnosed is too high for the worker to detect the internal fault, he can stand on the lifting platform and start the drive motor. The drive motor drives the moving shaft to rotate. Since the moving shaft is fixedly connected to the screw rod, the screw rod is located in the groove, and a fixed plate is fixedly connected in the groove. The screw rod is threadedly connected to the fixed plate. Therefore, when the screw rod rotates, it will move downward under the action of the fixed plate, and at the same time drive the sliding frame connected to the sliding rail to move toward the fixed plate. When the screw rod moves to no longer contact the fixed plate, the moving shaft is located in the first thread groove of the fixed plate and does not contact the fixed plate. At this time, the screw rod is in contact with the mounting plate and is threadedly connected in the second thread groove. Continue to rotate the screw rod until the bottom of the sliding frame abuts against the upper surface of the fixed plate. At this time, when the screw rod can no longer move downward, the lifting platform starts to move upward, and adjusts the drive motor according to the height. When descending, the screw rod rotates in the opposite direction. S4. When the worker needs the corresponding tool for diagnosis, he puts the tool in the placement frame. Since protective plates are installed on the front and rear sides of the lifting platform, a second motor connected to the end of the second rotating shaft is installed on the protective plate on the front side of the lifting platform. The second rotating shaft is set in the middle of the transmission main gear. Therefore, the transmission main gear rises with the rise of the lifting platform.
