Description

Technical Field

[0001] This utility model relates to the field of new energy wind power box-type substation technology, specifically a box-type substation. Background Technology

[0002] In power systems, prefabricated substations are compact power distribution equipment that organically combines functions such as high-voltage power reception, transformer voltage reduction, and low-voltage power distribution. In the field of new energy wind power generation, prefabricated substations are the core equipment for the collection and distribution of power in wind farms, and their operational stability and adaptability directly affect the efficiency and reliability of the entire wind power system.

[0003] However, in the existing technology, when the substation components inside the prefabricated substation malfunction or need to be replaced, the components are usually fixed inside the enclosure, which is a narrow space and difficult to operate, causing great inconvenience to the staff's inspection and maintenance work. This not only increases the inspection time and cost, but may also lead to incomplete inspection due to the inconvenience of operation, leaving safety hazards. At the same time, the installation requires the staff to enter the enclosure to carry out the installation work, which increases the workload of the staff. Therefore, we propose a prefabricated substation. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated substation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a substation outer casing. Several doors are evenly arranged on the front side of the substation outer casing via hinges. Several mounting seats are evenly arranged on the lower inner wall of the substation outer casing. Each mounting seat has a sliding groove, in which a slider is slidably mounted. A support frame is mounted on top of the slider, and a substation assembly is mounted on top of the slider. The substation assembly is fixedly connected to the support frame via fixing bolts. A threaded rod is rotatably mounted inside the mounting seat, penetrating the slider and threadedly connected to it. A cavity is also provided on the rear side of the mounting seat. A mounting shaft is rotatably mounted in the cavity via a bearing. A first bevel gear is connected to the mounting shaft via a key. The threaded rod penetrates the side wall of the cavity and extends into the cavity. A second bevel gear is connected to the threaded rod inside the cavity via a key, meshing with the first bevel gear. A worm gear is also connected to the mounting shaft via a key. A worm is rotatably mounted in the cavity, meshing with the worm wheel.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution: such as Figures 1-5 The diagram shows a prefabricated substation, including a substation outer casing 1. Several doors 2 are evenly arranged on the front side of the outer casing 1 via hinges. An air intake mesh plate 6 is provided on the rear outer wall of the outer casing 1. A top plate 3 is also provided on the top of the outer casing 1. First mesh plates 4 are provided on the left and right outer walls of the top plate 3. Several heat dissipation channels 7 are evenly arranged on the top plate 3. Several cooling fans 9 are also evenly arranged on the top of the outer casing 1. The cooling fans 9 can dissipate the heat generated by the internal components of the outer casing 1 during operation. Simultaneously, the air intake mesh plate 6, the first mesh plate 4, and the second mesh plate 8 form a complete gas flow path, thereby ensuring the efficiency and quality of heat dissipation.

[0021] The heat dissipation channel 7 has an installation cavity inside its side wall. A telescopic rod 21 is installed in the installation cavity. A limit rod 22 is installed at the end of the telescopic arm of the telescopic rod 21. A limit groove is provided on the second mesh plate 8 to cooperate with the limit rod 22. A return spring 23 is sleeved on the outside of the telescopic rod 22. One end of the return spring 23 is connected to the limit rod 22, and the other end of the return spring 23 is connected to the inner wall of the installation cavity.

[0022] Several mounting seats 5 are evenly arranged on the inner wall below the substation outer casing 1. Each mounting seat 5 has a sliding groove, in which a slider 10 slides. A support frame 11 is mounted on top of the slider 10, and a substation assembly 12 is mounted on top of the slider 10. The substation assembly 12 is fixedly connected to the support frame 11 by fixing bolts 13. A threaded rod 14 is rotatably mounted inside the mounting seat 5, passing through and threadedly connected to the slider 10. A cavity is also provided on the rear side of the mounting seat 5, in which a mounting shaft 15 is rotatably mounted via a bearing. A first bevel gear 16 is keyed onto the mounting shaft 15. The threaded rod 14 passes through the side wall of the cavity and extends into the cavity. A second bevel gear 17 is keyed onto the threaded rod 14 inside the cavity, and the second bevel gear 17 meshes with the first bevel gear 16. The mounting shaft 15 is also connected to a worm gear 19 via a key, and a worm 18 is rotatably mounted in the cavity. The worm 18 and the worm gear 19 mesh with each other. Rotating the worm 18 will drive the worm gear 19 to rotate, which in turn drives the threaded rod 14 to rotate through the first bevel gear 16 and the second bevel gear 17, thereby driving the slider 10 to move. This allows the support frame 11 to be pushed out from inside the substation outer box 1, which facilitates the maintenance or replacement of parts of the substation components 12 on the top of the support frame 11 by the staff. To a certain extent, it facilitates the staff to carry out related work. A motor 20 is also provided on the rear outer wall of the mounting base 5. The power output shaft of the motor 20 is connected to the worm 18 via a coupling. A limit plate is also provided on the front outer wall of the support frame 11, and the limit plate is slidably connected to the mounting base 5.

[0023] Working principle: When the substation component 12 generates heat during operation, the cooling fan 9 starts, expelling the hot air inside the substation outer casing 1 through the first mesh plate 4 on the top plate 3 and the heat dissipation channel 7 on the top plate 3. At the same time, external cold air enters the interior of the substation outer casing 1 through the air inlet mesh plate 6 on the rear outer wall of the substation outer casing 1, circulating in the gas flow path formed by the air inlet mesh plate 6, the first mesh plate 4, and the second mesh plate 8, forming an effective heat dissipation air path, ensuring heat dissipation efficiency and quality.

[0024] When maintenance or replacement of parts is required for substation component 12, the operator starts the motor 20 on the outer rear wall of the mounting base 5. The power output shaft of the motor 20 drives the worm gear 18 to rotate via a coupling. The worm gear 18 meshes with the worm wheel 19. When the worm wheel 19 rotates, it drives the mounting shaft 15 to rotate via a key connection. A first bevel gear 16 is keyed onto the mounting shaft 15. The first bevel gear 16 meshes with a second bevel gear 17 keyed onto the threaded rod 14. Therefore, when the first bevel gear 16 rotates, it drives the second bevel gear 17 and the threaded rod 14 to rotate. The threaded rod 14 passes through the slider 10 and is threadedly connected to the slider 10. When the threaded rod 14 rotates, the slider 10 slides in the groove of the mounting base 5. The top of the slider 10 is provided with a support frame 11, and the top of the support frame 11 is provided with a substation component 12. Therefore, when the slider 10 moves, it will drive the support frame 11 and the substation component 12 to move together. In this way, the substation component 12 can be pushed out from the substation outer box 1, which is convenient for the staff to carry out maintenance or parts replacement. At the same time, when installing the substation component 12, the staff can remove the support frame 11 from the substation outer box 1 through the above steps, which facilitates the staff to install the substation component 12. With the use of the self-locking function of the worm gear 19 and the worm 18, the installation quality of the substation component 12 is guaranteed.

[0025] When the second mesh plate 8 needs to be cleaned, the staff pulls the second mesh plate 8 outward, so that the limiting rod 21, under the action of the limiting groove, will push the telescopic rod 21 to retract, and the second mesh plate 8 can be disassembled. After the second mesh plate 8 is cleaned, the staff inserts the second mesh plate 8 into the heat dissipation channel 7. Under the action of the telescopic rod 21 and the return spring 23, the limiting rod 22 is inserted into the limiting groove, thereby completing the fixation of the second mesh plate 8.
