[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0048] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0049] See also Figures 1 to 17 As shown, the present invention provides a modular wind power generation box transformer, including a support part 1, which provides a load-bearing and installation platform for the entire device, wherein all primary high-voltage live parts are sealed and not exposed, and all effectively isolated surfaces are shielded and grounded to protect the daily maintenance safety of personnel;

[0050] A docking portion 2 is provided in the middle of the support portion 1, and a transformer 3 is provided on the support portion 1 through the docking portion 2 (the overall structure of the transformer 3 is relatively mature at present, so the specific structure is not described in detail), wherein the docking portion 2 is used to lock the transformer 3 and realize the access of the transformer 3. The docking portion 2 can not only lock the transformer 3 on the upper part of the support portion 1, but also can be inserted into the inside of the transformer 3 to realize the electrical connection between the transformer 3 and the docking portion 2;

[0051] The transformer 3 is provided with heat dissipation parts 4 on both sides, and the lower end of the heat dissipation parts 4 is fixedly connected to the upper end of the support part 1, and the heat dissipation parts 4 provide heat dissipation for the oil inside the transformer 3, thereby reducing the working temperature of the transformer 3;

[0052] A combination part 5 is provided on one side of the transformer 3, and a high-voltage module and a low-voltage module are integrated inside the combination part 5. When the combination part 5 is installed on one side of the transformer 3, it can be locked by structural limit, and is electrically connected to the inside of the transformer 3 through a plug 507;

[0053] The lower end of the combined part 5 cooperates with the docking part 2 , and when the docking part 2 is inserted into the transformer 3 , the combined part 5 can also be squeezed to lock the combined part 5 .

[0054] Specifically, during the installation of the equipment, the support part 1 needs to be placed on a reinforcement platform and reinforced, and then the transformer 3 is assembled on the middle of the upper end of the support part 1 by a lifting device such as a crane. After the alignment is completed, the position is adjusted and slowly and naturally falls into place. During the falling process, the lower end of the transformer 3 is inserted into the interior of the guide seat 201 to achieve the installation of the transformer 3.

[0055] Then, the heat dissipation part 4 is fixed to the upper part of the support part 1, and the inside of the heat dissipation part 4 is connected to the transformer 3, so that the oil inside the transformer 3 flows into the heat dissipation part 4 for heat dissipation, so as to reduce the working temperature of the transformer 3;

[0056] Then, the upper end of the combined part 5 in an inclined state is mounted on the transformer 3, and then the combined part 5 is rotated downward with the mounting position as the axis until the combined part 5 is in a vertical state. At this time, the combined part 5 can be electrically connected with the transformer 3, and the combined part 5 can also be automatically locked;

[0057] Finally, by adjusting the docking part 2, the docking part 2 is connected to the transformer 3 and the transformer 3 is locked. At the same time, in the process of adjusting the docking part 2, the cabinet 506 can also be locked, so that the transformer 3 and the combination part 5 can be efficiently installed.

[0058] Based on this, by introducing modular design, each unit in the traditional box-type transformer is modularly designed, which can not only greatly reduce the overall footprint of the box-type transformer, but also cooperate with the modular design between each component to achieve faster assembly and ensure a certain assembly accuracy and assembly stability.

[0059] See also Fig.13As shown, the docking portion 2 includes a guide seat 201, a rotating screw 202, a moving seat 203, a lifting frame 204, a docking seat 205, a linkage rod 206, a locking plate 207 and a circuit breaker 208. The guide seat 201 is fixedly connected to the interior of the support portion 1, the rotating screw 202 is rotatably connected to the interior of the guide seat 201, two moving seats 203 are provided, and the two moving seats 203 are slidably arranged at both ends of the interior of the guide seat 201, the interior of the moving seat 203 is threadedly connected to the outer edge of the rotating screw 202, and one end of the lifting frame 204 is connected to the The internal rotation connection of the mobile seat 203, the docking seat 205 is slidably connected to the internal of the guide seat 201, and the upper end of the docking seat 205 cooperates with the lower end of the transformer 3, both ends of the docking seat 205 are rotatably connected to the other end of the corresponding lifting frame 204, one end of the linkage rod 206 is rotatably connected to the two ends of the docking seat 205, the locking plate 207 is slidably arranged in the interior of the guide seat 201, one end of the locking plate 207 is rotatably connected to the other end of the linkage rod 206, and the other end of the locking plate 207 cooperates with the lower end of the transformer 3, and the circuit breaker 208 is connected to the support The support part 1 is fixedly connected inside, and the circuit breaker 208 is connected to the docking seat 205 through a conductive cable. The outer edge of the rotating screw 202 is provided with three sections of threads of the same specification. The threads opened at both ends of the rotating screw 202 have the same direction, wherein the threads in the middle are in opposite directions. The threads opened at both ends of the rotating screw 202 have the same direction and are in opposite directions to the threads in the middle section. The threads at one end and the middle section of the rotating screw 202 are respectively connected to the internal threads of the corresponding moving seat 203, and the threads at the other end of the rotating screw 202 are connected to the internal threads of the locking pin 502. The components connected by three-section threads are arranged as a moving seat 203-moving seat 203-locking pin 502. When the rotating screw 202 rotates, the moving seat 203 connected by the threads at both ends of the rotating screw 202 can move horizontally toward or away from the outer edge of the rotating screw 202 due to the opposite threads at both ends of the rotating screw 202. Therefore, the moving seat 203 drives one end of the lifting frame 204 to move, so that the lifting frame 204 can drive the docking seat 205 to extend and retract vertically inside the guide seat 201.

[0060] At the same time, the rotation of the rotating screw rod 202 can also drive the extension and retraction of the locking pin 502 through the threaded connection, and realize linkage in the same manner as the extension and retraction process of the docking seat 205 .

[0061] In the structure of the docking part 2, when the alignment of each module is completed, the movable seat 203 threadedly connected thereto can be driven to slide horizontally inside the guide seat 201 by rotating the rotating screw 202. Since the movement of the movable seat 203 drives one end of the lifting frame 204 to move, the other end of the lifting frame 204 squeezes the docking seat 205 to move vertically inside the guide seat 201, so that the docking seat 205 gradually extends out of the guide seat 201 and is inserted into the lower end of the transformer 3, so that the inside of the guide seat 201 is electrically connected to the transformer 3;

[0062] At the same time, the rotation of the screw rod 202 can also drive the locking pin 502 which is also threadedly connected to move out and extend, and the locking pin 502 is inserted into the interior of the limit seat 503, thereby locking the limit seat 503 and preventing the limit seat 503 from shrinking into the interior of the support seat 501, thereby locking the cabinet 506 and preventing the cabinet 506 from moving;

[0063] At the same time, when the docking seat 205 extends and moves, the docking seat 205 squeezes one end of the linkage rod 206, so that the other end of the linkage rod 206 squeezes the interior of the guide seat 201 from which the locking plate 207 gradually extends. At this time, the locking plate 207 is also inserted into the interior of the transformer 3 to lock the transformer 3 and improve the stability of the transformer 3 on the upper part of the support part 1.

[0064] See also Figure 2 As shown, the interior of the support part 1 is divided into an auxiliary source room, a docking room and a communication room. The interior of the auxiliary source room is provided with switchgear, control equipment and related cables, etc., which distribute the received electric energy to users to protect, measure and distribute electric energy (the principle and working process here are very mature in the prior art, so they will not be described in detail). The docking part 2 is fixedly arranged inside the docking room, and the electrical connection between the transformer 3 and the interior of the auxiliary source room is realized through the docking part 2. The interior of the communication room is integrated with a communication module, which can monitor the data of the transformer 3 and the auxiliary source room, and exchange data with other intelligent devices to realize remote monitoring and control of the transformer 3 and the auxiliary source room.

[0065] See also Figure 3 , Figure 6 as well as Figures 8 to 11As shown, a docking plate 101 is provided on the upper part of the support part 1, and a mounting groove is provided inside the middle section of the docking plate 101. The opening of the mounting groove is provided as an inclined surface, and the inclined surface matches the lower end of the transformer 3. During the assembly of the transformer 3, the lower end of the transformer 3 first contacts the mounting groove in the middle of the docking plate 101. During the downward movement of the transformer 3, the lower end of the transformer 3 is gradually aligned and calibrated with the depth inside the mounting groove due to the structural restriction and guidance of the inclined surface of the mounting groove, thereby increasing the fault tolerance rate during the installation of the transformer 3, avoiding damage to the docking portion due to deviation in alignment, ensuring the accuracy of the installation of the transformer 3, and reducing the difficulty of installation.

[0066] See also Figures 1 to 4 As shown, the transformer 3 includes a main body 301, a docking port 302, a docking nut 303, a docking socket 304, a support frame 305 and a socket 306. The main body 301 is arranged on the upper part of the docking plate 101, the docking port 302 is arranged at both ends of the main body 301, and the interior of the docking port 302 is connected with the interior of the main body 301, the docking nut 303 is rotatably arranged on the outer edge of the docking port 302, the docking socket 304 is fixedly arranged at the lower end of the main body 301, the docking socket 304 is electrically connected to the equipment inside the main body 301, the docking socket 304 is vertically corresponding to the interior of the docking seat 205, the lower end of the support frame 305 is fixedly connected to the main body 301, and the support frame 305 is matched with the interior of the docking plate 101;

[0067] In this manner, the support frame 305 can provide stable support during the storage or placement of the main body 301; during the installation of the main body 301, the support frame 305 is adjusted to a position vertically corresponding to the docking plate 101, and the support frame 305 is guided by the docking plate 101 and gradually cooperates with the deep inside of the docking plate 101. A plurality of sockets 306 are provided at the main body 301, and the plurality of sockets 306 are respectively electrically connected to the corresponding interior of the main body 301 and the docking socket 304 through cables, and the interface of the socket 306 is arranged vertically corresponding to the combination part 5. When the plug 507 is inserted in a vertical arc, the vertically opened interface has the same moving path as the plug 507, which can ensure that the socket 306 is in contact with the plug 507, and an electrical connection is achieved when the two are in contact. At this time, the low-voltage module inside the combination part 5 is electrically connected through the docking of the corresponding socket 306 and the plug 507, and then the docking socket 304 is electrically connected to the low-voltage module through the cable of the socket 306;

[0068] The high-voltage module inside the assembly part 5 is electrically connected by docking the corresponding socket 306 with the plug 507, thereby making the main body 301 electrically connected to the high-voltage module inside the assembly part 5, completing the electrical connection between the assembly part 5 and the main body 301;

[0069] When the docking socket 304 is assembled with the docking seat 205 , the electrical connection between the low voltage module and the circuit breaker 208 is achieved.

[0070] See also Figure 2 , Figure 4 as well as Figures 8 to 11 As shown, a supporting foot is provided at the lower end of the supporting frame 305, and the lower end of the supporting foot is arranged to be inclined, and the supporting foot cooperates with the mounting groove in the middle of the docking plate 101. The oblique line at the lower end of the supporting foot cooperates with the inclined surface at the opening of the mounting groove of the docking plate 101 to guide, thereby further promoting the docking calibration between the supporting frame 305 and the mounting groove of the docking plate 101.

[0071] See also Fig.10 and Fig.11 As shown, the overall height of the docking socket 304 is half the height of the support frame 305, so that when the main body 301 is placed or stored, the docking socket 304 can be kept away from the load-bearing plane, thereby preventing the docking socket 304 from being damaged by collision; at the same time, the docking socket 304 can only contact the docking plate 101 after the support frame 305 is inserted into the installation groove of the docking plate 101 and calibrated, which can prevent the docking socket 304 from being damaged by collision with the docking plate 101.

[0072] See also Figures 1 to 3 as well as Figure 5 As shown, the heat dissipation part 4 includes a mounting frame 401, a limiting column 402, a radiator 403 and a docking joint 404. The mounting frame 401 is fixedly connected to the upper part of the docking plate 101 by bolts, the limiting column 402 is slidably connected to the inside of the mounting frame 401, and a guide groove matched with the limiting column 402 is provided inside the mounting frame 401. The guide groove provides positioning and guidance for the limiting column 402 during installation. Both ends of the radiator 403 are fixedly connected to a plurality of limiting columns 402, and the limiting columns 402 are fixedly connected to the edges of the heat dissipation fins of the radiator 403, and the heat dissipation fins of the radiator 403 are combined into a whole to enhance the structural strength. One end of the docking joint 404 is fixedly connected to the input port and the output port of the radiator 403, and the other end of the docking joint 404 is matched with the inside of the docking port 302.

[0073] During the assembly process, the mounting frame 401 is first mounted on the upper part of the docking plate 101 and horizontally corresponds to the main body 301, and the mounting frame 401 is fixedly connected to the docking plate 101 by bolts. Then the blocking frame on one side of the mounting frame 401 is opened, and then the radiator 403 is slid into the interior of the mounting frame 401 until the docking joint 404 of the radiator 403 is inserted into the interior of the corresponding docking port 302. At this time, the docking nut 303 needs to be rotated and tightened on the outer edge of the docking joint 404 to fix the docking joint 404 and the docking port 302. At this point, the connection between the radiator 403 and the main body 301 is completed. Then the blocking frame of the mounting frame 401 is installed back to its original position and fixed by bolts to complete the internal limit of the radiator 403 in the mounting frame 401.

[0074] See also Figure 3 As shown, positioning grooves are also provided at both ends of the docking plate 101, and the positioning grooves cooperate with the lower end of the mounting frame 401. The positioning grooves provide positioning for the installation of the mounting frame 401, ensuring that after the mounting frame 401 is installed, it is ensured that the mounting frame 401 and the transformer 3 are in a horizontal corresponding state, thereby ensuring assembly accuracy.

[0075] See also Figure 7 As shown, the inner opening of the docking port 302 is set to be cone-shaped, and the outer edge of the other end of the docking joint 404 is set to be cone-shaped. The cone shape inside the docking port 302 can provide guidance for the insertion process of the docking joint 404, thereby improving the docking accuracy. At the same time, the cone shape of the docking joint 404 can also increase the contact area on the inner side of the docking port 302, thereby improving the sealing performance when the docking port 302 and the docking joint 404 are docked.

[0076] See also Figure 2 as well as Figures 14 to 17 As shown, the combined part 5 includes a support seat 501, a locking pin 502, a limiting seat 503, an elastic reset member 504, a limiting ridge 505, a cabinet 506, a plug 507, a bearing seat 508 and a mounting roller 509. The support seat 501 is fixedly connected to the support part 1, the locking pin 502 is slidably arranged inside the guide seat 201, and the interior of one end of the locking pin 502 is threadedly connected to one end of the rotating screw 202, the limiting seat 503 is slidably arranged inside the support seat 501, and the interior of one end of the limiting seat 503 is threadedly connected to the locking pin 502. The other end cooperates, the elastic reset member 504 is arranged between the limit seat 503 and the support seat 501, the lower end of the limit ridge 505 cooperates with the upper end of the limit seat 503, the lower end of the cabinet 506 is fixedly connected to the upper end of the limit ridge 505, and the plug 507 is fixedly arranged on the side of the cabinet 506 facing the transformer 3. The multiple plugs 507 are correspondingly connected to the high-voltage module and the low-voltage module inside the cabinet 506 through cables, the bearing seat 508 is fixedly connected to the transformer 3, and one end of the mounting roller 509 is fixedly connected to the cabinet 506;

[0077] When the combination part 5 and the transformer 3 need to be installed, the cabinet 506 needs to be tilted first, so that the installation roller 509 matches the opening of the bearing seat 508, and then the cabinet 506 needs to be moved downward so that the installation roller 509 is completely inserted into the interior of the bearing seat 508. When the cabinet 506 is rotated to a vertical state, the installation roller 509 is limited by the volume structure of the bearing seat 508 and is in a locked state and cannot move;

[0078] When the cabinet 506 is about to be in a vertical state, the cabinet 506 drives the limiting ridge 505 to squeeze the limiting seat 503, so that the limiting seat 503 shrinks and enters the interior of the support seat 501 until the cabinet 506 is in a vertical state. At this time, the limiting seat 503 loses the squeezing of the limiting ridge 505 and is elastically squeezed by the elastic reset member 504 and extends out of the interior of the support seat 501. At this time, the installation and limiting of the cabinet 506 are completed;

[0079] When the rotating screw 202 rotates, the locking pin 502 extends and is inserted into the interior of the limit seat 503, thereby achieving structural limitation of the limit seat 503, thereby preventing the limit seat 503 from shrinking into the interior of the support seat 501, causing the limit ridge 505 to lose its limit and move, thereby increasing the stability of the cabinet 506 in the installed state.

[0080] See also Fig.16 and Fig.17 As shown, the other end of the mounting roller 509 cooperates with the interior of the bearing seat 508, and the other end of the mounting roller 509 is set to a fan shape, which cooperates with the interior of the bearing seat 508. When the mounting roller 509 is installed into the interior of the bearing seat 508, it needs to be in an inclined state to be able to cooperate with the opening of the bearing seat 508. At this time, the mounting roller 509 can be inserted into the interior of the bearing seat 508, and then the mounting roller 509 is rotated to make the fan shape in a vertical state. At this time, the fan shape is limited by the structural volume inside the bearing seat 508 and cannot move. It can only be moved out of the interior of the bearing seat 508 after the mounting roller 509 is rotated and tilted. At this time, the bearing seat 508 realizes the limit locking of the mounting roller 509, thereby improving the stability of the mounting roller 509 after it is installed into the interior of the bearing seat 508.

[0081] The working principle of the present invention is as follows: during the installation of the equipment, the support part 1 needs to be placed on a reinforcement platform, and then the transformer 3 is first assembled on the middle of the upper end of the support part 1 by a crane, and at this time, the lower end of the transformer 3 is inserted into the interior of the guide seat 201 to achieve the installation of the transformer 3;

[0082] Then, the heat dissipation part 4 is fixed to the upper part of the support part 1, and the inside of the heat dissipation part 4 is connected to the transformer 3, so that the oil inside the transformer 3 flows into the heat dissipation part 4 for heat dissipation, so as to reduce the working temperature of the transformer 3;

[0083] Then, the upper end of the combined part 5 in an inclined state is mounted on the transformer 3, and then the combined part 5 is rotated downward with the mounting position as the axis until the combined part 5 is in a vertical state. At this time, the combined part 5 and the transformer 3 are in an electrically connected state, and the combined part 5 can also be automatically locked;

[0084] Then, by rotating the rotating screw 202, the moving seat 203 threadedly connected thereto is driven to slide horizontally inside the guide seat 201. The movement of the moving seat 203 drives one end of the lifting frame 204 to move, so that the other end of the lifting frame 204 squeezes the docking seat 205 to move vertically inside the guide seat 201, so that the docking seat 205 gradually extends out of the guide seat 201 and is inserted into the lower end of the transformer 3, so that the inside of the guide seat 201 is electrically connected to the transformer 3.

[0085] At the same time, the rotation of the screw rod 202 can also drive the locking pin 502 which is also threadedly connected to move out and extend, and the locking pin 502 is inserted into the interior of the limit seat 503, thereby locking the limit seat 503 and preventing the limit seat 503 from shrinking into the interior of the support seat 501, thereby locking the cabinet 506 and preventing the cabinet 506 from moving;

[0086] At the same time, when the docking seat 205 extends and moves, the docking seat 205 squeezes one end of the linkage rod 206, so that the other end of the linkage rod 206 squeezes the interior of the guide seat 201 from which the locking plate 207 gradually extends. At this time, the locking plate 207 is also inserted into the interior of the transformer 3 to lock the transformer 3 and improve the stability of the transformer 3 on the upper part of the support part 1.

[0087] In addition, it should be noted that the core of the present invention is to adjust the conventional box-type design to a modular type, and to quickly assemble the modules to reduce the floor space and construction period. The key description part is mostly the assembly method and docking method of each module. As for the specific composition and principle of each module, most of them are relatively mature technologies in existing applications, so they are not involved in detail.

[0088] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
