Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for transformers, and specifically to a disassembly and assembly component for a motor inside a transformer. Background Technology

[0002] Currently, 10kV dry-type transformers in power distribution systems generally adopt an assembly method of transformer + cooling fan + casing. The cooling fan is fixedly installed at the bottom of the transformer, and the transformer is further isolated from the outside by a casing to prevent small animals from entering and causing unplanned shutdowns. However, considering the need for space and cost savings in power distribution, some production equipment is only powered by a single transformer without a backup. When the cooling fan at the bottom of the transformer fails due to prolonged operation, if the fan is not replaced, the transformer cannot operate at high load and must be derated. Replacing the fan requires shutting down the transformer to ensure the safety of personnel. Due to the special nature of transformer power supply, transformer power outages have a significant impact and can cause substantial losses to the company. Utility Model Content

[0003] This invention addresses the problem of replacing faulty or damaged cooling fans at the bottom of transformers in real time without stopping the transformer's operation. It provides a component for disassembling and assembling motors within transformers, enabling the replacement of faulty or damaged fans at the bottom of transformers without stopping the transformer's operation and ensuring the safety of workers. This avoids losses caused by transformer power outages and safeguards the lives of workers.

[0004] The technical solution adopted in this utility model is:

[0005] A disassembly and assembly assembly for a motor inside a transformer is provided, comprising:

[0006] A fixing plate is disposed on the outer wall of the fan, and a first groove is formed on the outer wall of the fixing plate. A cavity communicating with the first groove is formed inside the fixing plate. A locking block is located inside the cavity and can rotate within the cavity about the center line of the cavity. A fixing rod is disposed at one end on the outer wall of the locking block and the other end extends to the outside of the fan through the first groove. The locking block can be removed from the fixing plate from inside the cavity through the first groove by the fixing rod.

[0007] Optionally, the outer wall of the fixing rod is provided with an L-shaped connecting rod, and the other end of the connecting rod is provided with a second locking block; the outer wall of the fixing plate is provided with a fixing block, and the outer wall of the fixing block is provided with a limiting groove for the connecting rod and the second locking block to enter.

[0008] Optionally, it also includes a housing, with a frame inside the housing and a baffle at one end of the frame to prevent the fan from falling off the frame.

[0009] Optionally, a maintenance hole is provided on the side wall of the housing for the fan and the fixing plate to pass through; a support plate located in the maintenance hole is hinged to the side wall of the housing.

[0010] Optionally, the support plate includes a first support plate unit and a second support plate unit. The first support plate unit is hinged to the side wall of the housing, and the hinged part is located in the maintenance hole. The second support plate unit is hinged to the first support plate unit. A sliding groove communicating with the maintenance hole is also provided on the side wall of the housing. A sliding rod located in the sliding groove is hinged to the side wall of the second support plate unit. The sliding rod is slidably connected to the housing through the sliding groove.

[0011] Optionally, a second groove is provided on the side wall of the second support plate unit, and a roller located in the second groove is hinged to the second support plate unit.

[0012] Optionally, a fixing ring is provided on the outer wall of the housing, and a fixing buckle that engages with the fixing ring is provided on the outer wall of the second support plate unit.

[0015] Optionally, a suspension part is provided on the outer wall of the housing for suspending the fixing rod.

[0016] The beneficial effects of this utility model are:

[0017] When a fan at the bottom of a transformer malfunctions and needs replacement, workers hold a fixing rod and insert the end of the rod with a locking block into the transformer's outer casing. The inserted rod then inserts the locking block into the first groove on the fixing plate, allowing the block to pass through the groove and into the cavity. Workers then rotate the fixing rod, causing the locking block to rotate until it is fully engaged and will not fall out of the groove. At this point, workers can pull the fan outwards with the fixing rod, detaching it from the bottom of the transformer. The fan is then removed through the outer casing. Next, the first locking block on the fixing rod is inserted into the first groove on the fixing plate of a working fan, positioning it in the cavity connected to the groove. The fan is then mounted on the transformer's outer casing and pushed into the bottom of the transformer, completing the fan replacement and installation. This process ensures worker safety and avoids losses caused by transformer power outages. Attached Figure Description

[0032] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0033] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0034] Example

[0035] like Figure 1 and Figure 3 As shown, this embodiment discloses a disassembly and assembly assembly for the motor inside transformer 3, comprising:

[0036] A fixing plate 6 is provided on the outer wall of the fan 4. A first groove 60 is provided on the outer wall of the fixing plate 6, and a cavity 61 communicating with the first groove 60 is provided inside the fixing plate 6.

[0037] The locking block is located inside the cavity 61 and can rotate within the cavity 61 about the center line of the cavity 61;

[0038] The fixing rod 5 has one end located on the outer wall of the locking block, and the other end extends to the outside of the fan 4 through the first groove 60;

[0039] The locking block can be removed from the cavity 61 through the first groove 60 by the fixing rod 5 from the fixing plate 6.

[0040] When the fan 4 at the bottom of transformer 3 malfunctions and needs replacement, the worker holds the fixing rod 5 and inserts the end of the fixing rod 5 with the locking block into the outer casing 1 of transformer 3. The inserted fixing rod 5 then inserts the locking block into the first groove 60 on the fixing plate 6, allowing the locking block to then enter the cavity 61 through the first groove 60. At this time, the worker rotates the fixing rod 5, thereby rotating the locking block on the fixing rod 5 until the locking block is fully engaged in the cavity 61 and will not fall out of the first groove 60. At this point, the worker can hold the fixing rod 5 towards the outside of transformer 3. Pull the fan 4 in the direction of the direction to detach it from the bottom of the transformer 3. Then, remove the fan 4 through the outer casing 1 of the transformer 3. This completes the removal of the faulty fan 4. Next, insert the first locking block 50 on the fixing rod 5 into the first groove 60 in the fixing plate 6 of the other faultless fan 4, so that the first locking block 50 is located in the cavity 61 communicating with the first groove 60. Then, place the fan 4 on the outer casing 1 of the transformer 3 and push it into the bottom of the transformer 3 through the casing 1. This completes the replacement and installation of the fan 4, ensuring the safety of the staff and avoiding the loss caused by the power outage of the transformer 3.

[0041] In one embodiment, such as Figure 1 and Figure 2 As shown, the outer wall of the fixing rod 5 is provided with an L-shaped connecting rod 51, and the other end of the connecting rod 51 is provided with a second locking block 510; the outer wall of the fixing plate 6 is provided with a fixing block 62, and the outer wall of the fixing block 62 is provided with a limiting groove 620 for the connecting rod 51 and the second locking block 510 to enter.

[0042] In use, a connecting rod 51 is provided on the outer wall of the fixed rod 5, and a second locking block 510 is provided at the other end of the connecting rod 51. A fixing block 62 is provided on the outer wall of the fixing plate 6, and a limiting groove 620 is provided on the fixing block 62 for the connecting rod 51 and the second locking block 510 to enter. This improves the operability of the fixed rod 5 on the fan 4. Specifically, after the first locking block 50 on the fixed rod 5 enters the cavity 61 through the groove, rotating the fixed rod 5 causes the second locking block 510 of the connecting rod 51 on the outer wall of the fixed rod 5 to enter the limiting groove 620 in the fixing block 62, thus improving the operator's operability of the fan 4.

[0043] In one embodiment, such as Figure 3 As shown, it also includes a housing 1, and a frame 2 is provided inside the housing 1. A baffle 20 is provided at one end of the frame 2 to prevent the fan 4 from falling off the frame 2.

[0044] When in use, since the maintenance and replacement of the fan 4 is carried out by sliding it into the frame 2 from one end of the frame 2, in order to prevent the fan 4 from falling off the frame 2, a baffle 20 is set at the other end of the frame 2 to prevent the fan 4 from falling off when sliding in the frame 2.

[0045] In one embodiment, such as Figure 3 and Figure 4 As shown, a maintenance hole 10 is provided on the side wall of the housing 1 for the fan 4 and the fixing plate 6 to pass through; a support plate 7 is hinged to the side wall of the housing 1 and located in the maintenance hole 10.

[0046] In order to facilitate the maintenance and replacement of the fan 4 that has malfunctioned or is damaged during use, a maintenance hole 10 is opened on the side wall of the housing 1, and a support plate 7 is hinged in the maintenance hole 10. After the maintenance and replacement of the fan 4 is completed, the housing 1 can be closed by rotating the support plate 7 to prevent small animals from entering the housing 1 and affecting the normal operation of the transformer 3.

[0047] In one embodiment, such as Figure 4 As shown, the support plate 7 includes a first support plate unit 70 and a second support plate unit 71. The first support plate unit 70 is hinged to the side wall of the housing 1, and the hinged part is located in the maintenance hole 10. The second support plate unit 71 is hinged to the first support plate unit 70. A sliding groove 11 communicating with the maintenance hole 10 is also provided on the side wall of the housing 1. A sliding rod 72 located in the sliding groove 11 is hinged to the side wall of the second support plate unit 71. The sliding rod 72 is slidably connected to the housing 1 through the sliding groove 11.

[0048] In use, the support plate 7 is divided into a first support plate unit 70 and a second support plate unit 71 that are hinged to each other. The first support plate unit 70 is hinged to the housing 1, and the hinge point between the first support plate unit 70 and the housing 1 is located inside the maintenance hole 10. A sliding groove 11 connected to the maintenance hole 10 is opened on the side wall of the housing 1. The dimension along the height direction of the maintenance hole 10 is smaller than the height of the maintenance hole 10. That is, when the second support plate unit 71 moves and adjusts in the sliding groove 11 by sliding rod 72, a structure with a right-angled triangle cross section can be formed between the first support plate unit 70, the second support plate unit 71 and the side wall of the housing 1, which facilitates the support of the fan 4.

[0049] In one embodiment, such as Figure 5 As shown, a second groove 710 is provided on the side wall of the second support plate unit 71, and a roller 711 located in the second groove 710 is hinged to the second support plate unit 71.

[0050] In use, when the first support plate unit 70 and the second support plate unit 71 are opened, a right-angled triangular structure is formed between the first support plate unit 70, the second support plate unit 71, and the side wall of the housing 1, which facilitates support for the fan 4. A second groove 710 is formed on the contact surface between the second support plate unit 71 and the fan 4, and a roller 711 hinged to the second support plate unit 711 is placed in the second groove 710, which facilitates the movement of the fan 4 from the outside of the housing 1 to the inside of the housing 1 for replacement, making the operation smoother.

[0051] In one embodiment, a retaining ring (not shown in the figure) is provided on the outer wall surface of the housing 1, and a retaining buckle (not shown in the figure) is provided on the outer wall surface of the second support plate unit 71 to engage with the retaining ring.

[0052] After the fan 4 is installed, when the fixing rod 5 is removed from the maintenance hole 10, the second support plate unit 71 on the housing 1 is retracted, so that the maintenance hole 10 is covered by the first support plate unit 70 and the second support plate unit 71, preventing small animals from crawling into the housing 1 and affecting the operating transformer 3. After the first support plate unit 70 and the second support plate unit 71 have covered the maintenance hole 10, the fixing buckle on the outer wall of the second support plate unit 71 is engaged with the fixing ring on the outer wall of the housing 1, so that the second support plate unit 71 is fixed to the housing, ensuring that the second support plate unit 71 can cover the maintenance hole 10. It is worth noting that the fixing buckle on the second support plate unit 71 is located on the side wall of the second support plate unit 71, not on the side of the second support plate unit 71 used to support the fan 4, to avoid affecting the maintenance and replacement of the fan 4.

[0053] In one embodiment, such as Figure 3 and Figure 4 As shown, a buffer pad 201 is provided at the end of the baffle 20 facing the fan 4.

[0054] When in use, as the staff holds the fixed rod 5 and pushes the fan 4 toward the inside of the frame 2, in order to prevent the fan 4 from colliding with the baffle 20 on the frame 2 and causing damage, a buffer pad is set at the end of the baffle 20 facing the fan 4 to buffer the moving fan 4.

[0055] In one embodiment, the handheld end of the fixing rod 5 is an insulating part.

[0056] When in use, the end of the fixed rod 5 held by the operator is insulated, which can prevent the operator from being electrocuted when operating the fixed rod 5.

[0057] In one embodiment, such as Figure 3 and Figure 4 As shown, a suspension part 8 is provided on the outer wall surface of the housing 1 for suspending the fixing rod 5.

[0058] To prevent the fixing rod 5 from being misplaced after use, a hanging part 8 is provided on the outer wall of the housing 1. The hanging part 8 can be used to hang the fixing rod 5 so that it can be easily picked up by the staff.

[0059] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other.
