Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a stable excitation cabinet. Background Technology

[0002] As a key component of synchronous generators, the excitation cabinet is responsible for accurately delivering DC excitation current to the generator rotor windings. This not only helps the generator start smoothly and establish an initial magnetic field, but also allows for flexible adjustment of the excitation current based on the real-time grid conditions during subsequent operation, stabilizing the output voltage and accurately allocating reactive power. With the continuous upgrading of technology and maintenance requirements, the efficiency and accuracy of maintenance work have become increasingly critical. Traditional excitation cabinets have limited internal space, requiring technicians to inspect electronic components inside the cabinet.

[0003] However, with current technology, the limited internal space of the cabinet and the rigid fixing of the shelves make it difficult for maintenance personnel to operate, affecting the quality and efficiency of maintenance work. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a stable excitation cabinet, which aims to improve the problem of rigid mounting brackets that make it difficult for maintenance personnel to operate.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A stable excitation cabinet includes a cabinet body. The cabinet body has two layers of shelves inside, each shelf having a slot. A limit block is fixedly connected to the lower surface of each shelf. A sliding frame is fixedly connected to the inner wall of the cabinet body. The outer wall of the limit block is slidably connected to the inner wall of the sliding frame. A fixing box is fixedly connected to the outer wall of the cabinet body. A movable disk is slidably connected to the inner wall of the fixing box. A connecting column is fixedly connected to the inside of the movable disk. A wedge is fixedly connected to the outer wall of one end of the connecting column, and the outer wall of the wedge is located within the slot. A positioning column is fixedly connected to the outer wall of the other end of the connecting column. An arc-shaped sleeve is rotatably connected to the outer wall of the fixing box. A rotating handle is fixedly connected to the outer wall of the arc-shaped sleeve. The outer wall of the connecting column is slidably connected to the inner wall of the arc-shaped sleeve. The outer wall of the positioning column is located within the outer wall of the arc-shaped sleeve. A first spring is fixedly connected to the outer wall of the movable disk. A pop-out component is provided on the inner wall of the cabinet body for popping out the shelves.

[0007] Preferably, the pop-out component includes a second spring, the outer wall of which is fixedly connected to the inner wall of the cabinet, and a push plate is fixedly connected to the outer wall of the second spring, the outer wall of which is disposed on the outer wall of the shelf.

[0008] Preferably, a support base is fixedly connected to the lower surface of the cabinet, and a positioning seat is fixedly connected to the lower surface of the support base.

[0009] Preferably, a hydraulic cylinder is fixedly connected to the outer wall of the support base, a movable frame is fixedly provided at the output end of the hydraulic cylinder, a slide rail is fixedly connected to the inner wall of the support base, and the outer wall of the movable frame is slidably connected to the outer wall of the slide rail.

[0010] Preferably, the movable frame has an inclined groove inside.

[0011] Preferably, a lifting block is slidably connected inside the supporting base frame, and guide posts are fixedly connected to the upper outer walls on both sides of the lifting block. The outer walls of the guide posts are slidably connected to the inner wall of the inclined groove.

[0012] Preferably, the inner wall of the lifting block is rotatably connected to a pulley.

[0013] Preferably, a cover plate is fixedly connected to the outer wall of the cabinet, and a hinge is fixedly connected to the outer wall of the cover plate. The hinge is installed on the inner wall of the cabinet through the cover plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, rotating the handles on both sides of the cabinet causes the arc-shaped sleeve to slide outward via the positioning post and the connecting post, causing the inclined block to disengage from the inner wall of the slot. At this time, the second spring rebounds and pushes the placement rack outward with the push plate until the limit block moves to one end of the slide frame, thereby providing maintenance personnel with a more spacious and comfortable operating space, facilitating the maintenance of electronic components on the placement rack, and improving the quality and efficiency of maintenance work.

[0016] 2. In this utility model, the output end of the hydraulic cylinder drives the moving frame to move to the right along the outer wall of the slide rail. The guide column uses the inclined groove to make the lifting block slide down in the support base until the pulley touches the ground and the positioning seat leaves the ground. Then the cabinet can be pushed to the designated position. After that, the hydraulic cylinder is turned on to drive the moving frame to move to the left. The lifting block makes the pulley move up until the positioning seat touches the ground, ensuring the stability of the cabinet and thus improving the flexibility of the device.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a stable excitation cabinet, comprising a cabinet body 1, with two layers of shelves 2 inside the cabinet body 1. Each shelf 2 has a slot 3 inside, and a limit block 5 is fixedly connected to the lower surface of the shelf 2. A sliding frame 4 is fixedly connected to the inner wall of the cabinet body 1, and the outer wall of the limit block 5 is slidably connected to the inner wall of the sliding frame 4. A fixing box 6 is fixedly connected to the outer wall of the cabinet body 1, and a movable disk 7 is slidably connected to the inner wall of the fixing box 6. A connecting column 8 is fixedly connected inside the movable disk 7, and one end of the connecting column 8 is fixed to the outer wall. A wedge block 9 is connected, and the outer wall of the wedge block 9 is set on the inner wall of the slot 3. A positioning post 11 is fixedly connected to the outer wall of the other end of the connecting post 8. An arc-shaped sleeve 12 is rotatably connected to the outer wall of the fixing box 6. A rotating handle 13 is fixedly connected to the outer wall of the arc-shaped sleeve 12. The outer wall of the connecting post 8 is slidably connected to the inner wall of the arc-shaped sleeve 12. The outer wall of the positioning post 11 is set on the outer wall of the arc-shaped sleeve 12. A first spring 10 is fixedly connected to the outer wall of the moving plate 7. A pop-out component is set on the inner wall of the cabinet 1. The pop-out component is used to pop out the placement rack 2.

[0026] Specifically, cabinet 1 supports the position of shelf 2, which provides stable support for various electrical components. Shelf 2 also provides fixed support for limit block 5. Cabinet 1 can fix the position of sliding frame 4, thus effectively supporting shelf 2 and limiting its sliding position. Cabinet 1 provides fixed support for fixing box 6, which supports the sliding position of movable tray 7. Movable tray 7 provides fixed support for connecting column 8, which can... The first spring 10 on the outer wall of the movable disk 7 generates a reverse force to drive the inclined block 9 to slide to the inner wall of the slot 3, thereby limiting the placement rack 2. At the same time, the connecting column 8 provides fixed support for the positioning column 11, and the fixing box 6 can support the rotation position of the arc sleeve 12. When the rotating handle 13 is rotated, the rotating handle 13 can drive the arc sleeve 12 to rotate, thereby moving the positioning column 11 outward. This allows the inclined block 9 to be disengaged from the inner wall of the slot 3 through the connecting column 8, facilitating subsequent maintenance of the electronic components inside the placement rack 2.

[0027] Reference Figure 2 and Figure 4 The pop-out component includes a second spring 15, the outer wall of which is fixedly connected to the inner wall of the cabinet 1, and a push plate 14 is fixedly connected to the outer wall of the second spring 15. The outer wall of the push plate 14 is set on the outer wall of the placement rack 2.

[0028] Specifically, the cabinet 1 provides fixed support for the second spring 15, and the second spring 15 can provide the force for the push plate 14 to move outward. When the inclined block 9 limits the placement rack 2, it can ensure the stability of the placement rack 2. When the inclined block 9 disengages from the inner wall of the slot 3, it can push the placement rack 2 outward, providing maintenance personnel with a more spacious and comfortable operating space. This facilitates maintenance personnel in using tools and performing various maintenance operations, avoiding inconvenience and fatigue caused by narrow space, and helping to improve the quality and efficiency of maintenance work.

[0029] Reference Figure 1 and Figure 5 A support base 16 is fixedly connected to the lower surface of the cabinet 1, and a positioning seat 17 is fixedly connected to the lower surface of the support base 16.

[0030] Specifically, the support base 16 provides fixed support for the cabinet 1, and the support base 16 can ensure the stability of the cabinet 1 at a fixed position through the positioning seat 17.

[0031] Reference Figure 5A hydraulic cylinder 18 is fixedly connected to the outer wall of the support base 16. A movable frame 19 is fixedly installed at the output end of the hydraulic cylinder 18. A slide rail 20 is fixedly connected to the inner wall of the support base 16. The outer wall of the movable frame 19 is slidably connected to the outer wall of the slide rail 20. An inclined groove 21 is opened inside the movable frame 19. A lifting block 22 is slidably connected inside the support base 16. Guide posts 23 are fixedly connected to the upper outer walls on both sides of the lifting block 22. The outer walls of the guide posts 23 are slidably connected to the inner wall of the inclined groove 21. A pulley 24 is rotatably connected to the inner wall of the lifting block 22.

[0032] Specifically, the support base 16 provides fixed support for the hydraulic cylinder 18, and when the hydraulic cylinder 18 is activated, its output end can drive the moving frame 19 to move. The support base 16 also provides fixed support for the slide rail 20, which ensures the orientation and stability of the moving frame 19 during movement. The support base 16 supports the lifting position of the lifting block 22, and the lifting block 22 provides fixed support for the guide column 23. When the moving frame 19 moves, the guide column 23 can be moved up and down through the inclined groove 21, thereby moving the lifting block 22 up and down, which in turn drives the pulley 24 to extend and retract. When the pulley 24 contacts the ground and causes the positioning seat 17 to detach from the ground, the entire unit can be moved, improving the flexibility of the excitation cabinet's layout. After the pulley 24 detaches from the ground, the positioning seat 17 contacts the ground to ensure the overall stability of the excitation cabinet.

[0033] Reference Figure 1 A cover plate 25 is fixedly connected to the outer wall of the cabinet 1, and a hinge 26 is fixedly connected to the outer wall of the cover plate 25. The hinge 26 is installed on the inner wall of the cabinet 1 through the cover plate 25.

[0034] Specifically, the cover 25 can be opened or closed inside the cabinet 1 via the hinge 26 to protect and inspect electronic components.

[0035] Working principle: In use, firstly, the hydraulic cylinder 18 is activated. The output end of the hydraulic cylinder 18 can drive the moving frame 19 to move to the right on the outer wall of the slide rail 20. Then, the guide column 23 can drive the lifting block 22 to slide downward inside the support base 16 through the inclined groove 21 until the pulley 24 contacts the ground and the positioning seat 17 is lifted off the ground. Then, by pushing the cabinet 1, the whole unit can be moved to the designated position. Then, the hydraulic cylinder 18 is activated again to drive the moving frame 19 to move to the left. The lifting block 22 can drive the pulley 24 to move upward until the positioning seat 17 contacts the ground, which can ensure the stability of the cabinet 1 and improve the flexibility of the device. When it is necessary to repair the electronic components in the placement rack 2, first, the cover plate 25 is opened by the hinge 26. Then, the corresponding two-sided rotating handles 13 of the placement rack 2 are rotated at the same time. Then, the arc-shaped sleeve 12 can drive the connecting column through the positioning column 11. 8 slides outward, which can drive the inclined block 9 to disengage from the inner wall of the slot 3. At this time, the second spring 15 rebounds, and the reverse force generated can push the push plate 14 to push the placement rack 2 outward until the limit block 5 moves to one end of the slide frame 4, so as to facilitate the maintenance of the electronic components on the placement rack 2. At the same time, the placement rack 2 is pressed inward until the limit block 5 moves to the other end of the slide frame 4. The first spring 10 rebounds, and the connecting column 8 can be driven inward by the moving plate 7, which can drive the inclined block 9 to slide to the inner wall of the slot 3 to limit the placement rack 2 and ensure the stability of the placement rack 2 inside the cabinet 1. That is, the excitation cabinet can not only achieve the function of popping out the placement rack 2 for maintenance, providing a more spacious and comfortable operating space for maintenance personnel and improving the maintenance effect, but also achieve the function of retracting the pulley 24, so as to accurately install the entire excitation cabinet into the predetermined position and improve the flexibility.
