Description

Technical Field

[0001] This utility model belongs to the technical field of maintenance devices, specifically relating to a fault early warning and rapid maintenance device for high-voltage motors in power plants. Background Technology

[0002] In existing power plant high-voltage motor operating systems, when abnormal conditions such as excessive current or severe imbalance occur, the protection relay will immediately activate, triggering a buzzer to sound continuously. At the same time, the corresponding fault indicator light of the motor circuit will flash. Based on the alarm indication, the operating personnel will quickly locate the relevant electrical switch cabinet, open the cabinet door, and conduct on-site inspection, testing, and troubleshooting of the internal motor circuit breakers, transformers, and integrated protection devices.

[0003] During use, because the motor is located deep inside the cabinet, maintenance requires the front half of the body to enter the cabinet. Frequent entry and exit to change tools makes operation inconvenient and prevents quick maintenance. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1-3 This is the first embodiment of the present utility model. This embodiment provides a power plant high-voltage motor fault early warning and rapid repair device, including a moving part, including a cabinet cavity 10, a cabinet door 11 and a buzzer 12. A swing arm 13 is rotatably connected to the back of the cabinet door 11. A slide bar 14 is fixedly connected to the bottom of the cabinet cavity 10. A slide plate 15 is slidably connected to the outside of the slide bar 14 and rotatably connected to the inner end of the swing arm 13. A mounting platform 16 is fixedly connected to the top of the slide plate 15.

[0028] Specifically, the cabinet door 11 and the sliding plate 15 are connected by a sliding strip 14. Since the cabinet door 11 and the cabinet cavity 10 are flipped up and down, the sliding plate 15 inside the cabinet cavity 10 will be pulled out during the flipping process of the cabinet door 11, thereby allowing the high-voltage motor above the mounting platform 16 to be moved out of the cabinet for quick maintenance.

[0029] Furthermore, a rotating head is provided on the top of the cabinet door 11, and a rotating connecting block is provided on the front of the cabinet cavity 10, and the two rotate relative to each other through a limiting shaft on the outside of the rotating connecting block.

[0030] The rotating head and the rotating connecting block are designed symmetrically and are located at the connection between the cabinet cavity 10 and the cabinet door 11. The cabinet door 11 can be stably rotated up and down by the limiting shaft.

[0031] Preferably, the mounting platform 16 consists of a bottom support bar and an upper mounting plate, and the edge of the mounting plate is provided with mounting holes for through bolts. The swing arm 13 consists of a connecting rod and rotating connecting seats at both ends, and the swing arms 13 are symmetrically distributed inside the cabinet cavity 10.

[0032] It should be noted that the mounting platform 16 is designed to be raised and placed above the slide plate 15, with sufficient space at the bottom for installing the high-voltage motor. The swing arms 13 are placed on both sides of the slide plate 15, which will not affect the installation and removal of the high-voltage motor during maintenance.

[0033] When in use, if the high-voltage motor malfunctions and triggers an alarm via buzzer 12, the operator can rotate the cabinet door 11 on the front of the cabinet cavity 10 when they reach the front of the cabinet. By pulling the handle, the cabinet door 11 is flipped up, exposing the internal space of the cabinet cavity 10. During the flipping process of the cabinet door 11, the end of the swing arm 13 pulls the slide plate 15, causing the slide plate 15 to slide outward under the limit of the slide bar 14, thus sending out the high-voltage motor inside. This makes the maintenance process quick and convenient, without the need to repeatedly enter and exit the cabinet cavity 10.

[0034] Example 2

[0035] Reference Figures 4-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a limiting component, including a fixing block 20. The fixing block 20 is fixedly connected to the top of the rotating head at the top of the cabinet door 11. A telescopic component 21 is provided at the top of the fixing block 20. A connecting block 22 is fixedly connected to the top of the telescopic component 21. A guide rod 23 is fixedly connected to the outside of the connecting block 22. A guide groove block 24 is fixedly connected to the top groove of the cabinet door 11. The telescopic component 21 includes a hollow rod 211. The hollow rod 211 is fixedly connected to the top of the fixing block 20. A sliding rod 212 is slidably connected inside the hollow rod 211. An inner rod 213, which is fixedly connected to the top of the fixing block 20, is slidably connected inside the sliding rod 212. The bottom of the sliding rod 212 is fixedly connected to the top of the fixing block 20 by a spring 214.

[0036] Specifically, during the process of flipping the cabinet door 11, the guide rod 23 will always slide along the arc inside the guide groove block 24. When the rotation of the cabinet door 11 is at its limit position, the elastic force of the spring 214 can be used to change the position of the guide rod 23, thereby keeping the cabinet door 11 always in the position of flipping 90 degrees.

[0037] Furthermore, the slide bar 212 has a circular groove inside, and the diameter of the inner rod 213 corresponds to the inner diameter of the circular groove. The guide groove inside the guide block 24 is composed of an arc groove and a straight groove, and the straight groove is located at the bottom end of the arc groove. The guide rod 23 is located inside the guide groove, and the diameter of the guide rod 23 corresponds to the width of the guide groove.

[0038] The guide rod 23 corresponds to the size of the guide groove, so that it can fit perfectly inside and will not cause the cabinet door 11 to loosen. At the same time, the cooperation between the arc groove and the straight groove can achieve the effect of limiting the position.

[0039] When in use, when the cabinet door 11 rotates, the rotating head at its top will drive the fixed block 20 to rotate, causing the guide rod 23 to start to rotate along the arc groove inside the guide groove block 24. After rotating to ninety degrees, the spring 214 releases its elastic force, causing the slide rod 212 to push the guide rod 23 out and into the straight groove. At this time, the cabinet door 11 cannot rotate and will not rotate, and is fixed in this position. When it is necessary to close the cabinet door 11, simply slide the connecting block 22 to move it to the connection between the arc groove and the straight groove. At this time, under the influence of gravity, the cabinet door 11 will automatically reset and rotate.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
