Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more particularly to a transformer with a heat dissipation module that is convenient to install. Background Art

[0002] In modern power systems, transformers are key equipment, and their performance and life depend largely on an effective heat dissipation system. Transformers generate a lot of heat during operation. In order to ensure their normal operation and extend their service life, they usually need to install a large radiator. However, since the size of the radiator is often relatively large, these protruding components are easily affected by external impact or vibration during the transportation of the transformer, which not only increases the difficulty and cost of transportation, but more importantly, increases the risk of damage to the equipment during transportation. Once the radiator is damaged, it will not only directly affect the heat dissipation efficiency of the transformer, but may also cause more serious problems such as oil leakage, thereby posing a potential threat to the safe operation of the entire power system.

[0003] In order to deal with transportation risks, a common practice is to disassemble the radiator before transportation. However, when the radiator is removed, the internal system of the transformer will be in direct contact with the external environment, which increases the risk of internal contamination of the equipment. External dust, moisture or other impurities may enter the transformer and cause irreversible contamination to its insulation system and cooling medium. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the problems existing in the prior art, the present invention provides a transformer that is convenient for installing a heat dissipation module to solve the technical problems mentioned in the background technology.

[0005] (II) Technical solution To achieve the above object, the present invention provides the following technical solutions: a transformer that facilitates the installation of a heat dissipation module, comprising a transformer body and a heat sink; A connection mechanism, comprising a fixed tube connected and installed on the side wall of the transformer body, an external tube connected and installed on the radiator, a cross sleeve and a fitting plate respectively installed in the external tube and the fixed tube, push rods respectively slidably connected in the two cross sleeves, a follower sleeve coaxially installed on the push rod, a counter sleeve coaxially arranged near one side of the two follower sleeves, a plurality of expansion grooves are evenly spaced on the side wall of the counter sleeve, and an expansion block is respectively slidably connected in each expansion groove; and The fixing mechanism comprises an internal groove provided in the follower sleeve, an adjusting rod is coaxially slidably connected in the internal groove, a tapered rod is coaxially mounted on the adjusting rod, contraction grooves having the same number as the expansion blocks are evenly spaced on the side walls of the tapered rod, a follower ball is respectively mounted on each of the expansion blocks, and the follower ball is slidably connected in the contraction groove.

[0006] Preferably, the connecting mechanism also includes a one-way groove formed on the two mating disks, and sealing disks are respectively installed on the two follower sleeves. When the two opposing sleeves are mated with each other, the sealing disks on both sides are respectively away from the two one-way grooves, and when the sealing disk is mated with the one-way groove, the expansion block is mated with the mating disk. This design realizes an automatic sealing function through the cooperation of the one-way groove and the sealing disk, keeps the passage open when the opposing sleeves are mated, and automatically seals when separated. At the same time, the cooperation between the expansion block and the mating disk further enhances the sealing effect, effectively preventing oil leakage and external pollution.

[0007] Preferably, the two push rods are respectively sleeved with tension springs, one end of the tension spring is fixedly connected to the push rod, and the other end of the tension spring is fixedly connected to the cross sleeve. The tension spring plays a role of power supply during the connection and separation process, ensuring the convenience of operation.

[0008] Preferably, a plurality of the expansion blocks are respectively provided with round heads. When the external tube is disconnected from the fixed tube, the sealing disk moves toward the direction of the fitting disk, and the round heads abut against the one-way groove. The design of the round heads not only provides a good guiding effect, but also ensures that the expansion blocks can smoothly enter the one-way groove.

[0009] Preferably, the fixing mechanism also includes a return spring fixedly mounted on the side of the adjusting rod away from the conical rod, the return spring abuts against the internal groove, a limit ring is installed in the internal groove, and when the conical rod is not subjected to force, the adjusting rod abuts against the limit ring under the action of the return spring. This design provides an automatic resetting function for the adjusting rod through the cooperation of the return spring and the limit ring, thereby ensuring the reliability of the locking mechanism, while also simplifying the operating process and improving the convenience of use.

[0010] Preferably, a bidirectional spring is slidably installed in the opposing sleeve, and the bidirectional spring and the two opposing sleeves are coaxially arranged. The design of the bidirectional spring provides a bidirectional elastic support, which can not only provide the necessary pressure during the connection process, but also assist in unlocking during separation, thereby improving the flexibility and reliability of the entire mechanism.

[0011] Preferably, two-way heads are installed on both sides of the two-way spring, and the two two-way heads are respectively inserted into the two conical rods. When the two opposing sleeves are in contact with each other, the two sides of the two-way spring also move to the position of the expansion blocks at both ends. The design of the two-way head enhances the connection stability between the two-way spring and the conical rod, and also provides a limit for the movement of the expansion block.

[0012] Preferably, an external disk is coaxially installed on the external tube, a fixed disk is coaxially installed on the fixed tube, and multiple sets of connecting bolts are installed between the external disk and the fixed disk. This design provides a reliable external fixing mechanism through the cooperation of the external disk, the fixed disk and the connecting bolts, which not only enhances the stability of the connection, but also facilitates the installation and disassembly operations, thereby improving the maintainability of the overall structure.

[0013] Preferably, at least three groups of heat sinks are symmetrically installed on both sides of the transformer body. The symmetrical installation of multiple groups of heat sinks not only improves the heat dissipation efficiency, but also ensures the uniformity of heat dissipation and effectively prevents local overheating.

[0014] Preferably, the transformer body and the plurality of heat sinks are filled with insulating heat dissipation oil. The use of the insulating heat dissipation oil not only provides good insulation performance but also improves heat dissipation efficiency. (III) Beneficial effects

[0015] Compared with the prior art, the present invention provides a transformer that facilitates the installation of a heat dissipation module, and has the following beneficial effects: First of all, the design realizes the modular design of the transformer body and the radiator. This detachable structure improves the transportation convenience of the equipment and effectively reduces the risk of damage to large radiators during transportation. By transporting the transformer body and the radiator separately, it not only reduces the difficulty of transportation, but also reduces the transportation cost, providing greater flexibility for long-distance transportation and installation of the equipment.

[0016] Secondly, the design adopts an innovative connection mechanism to achieve quick connection and separation between the radiator and the transformer body. This mechanism includes multiple components such as a push rod, a follower sleeve, and a counter sleeve. Through their synergistic effect, the simplicity and reliability of the connection process are ensured. Especially in the separation process, the design utilizes the characteristics of the tension spring to achieve an automatic sealing function, effectively preventing oil leakage and the entry of external contaminants.

[0017] Furthermore, the design introduces components such as adjusting rods, cone rods, and expansion blocks. These components together constitute a locking mechanism, which can automatically fix the radiator when it is separated from the transformer, ensuring the stability of the seal. In particular, the card-jointed design of the expansion block and the fitting disk further enhances the sealing effect. Even if it is subjected to vibration and impact during transportation, it can maintain a good sealing state. The bidirectional spring not only plays a guiding and auxiliary role in the installation process, but also serves as an unlocking mechanism during disassembly, ensuring the safety and controllability of the entire operation process. This design makes the installation and disassembly of the radiator simpler and safer, and reduces the possibility of operational errors.

[0018] Finally, this design effectively solves the contamination risks faced by traditional transformers during transportation through multiple sealing and locking mechanisms. Both the transformer body and the radiator can remain completely sealed in a separated state, eliminating the possibility of external contaminants entering, thereby ensuring the cleanliness and reliability of the equipment.

[0019] In summary, this transformer design that facilitates the installation of the heat dissipation module not only improves the convenience of transportation and installation of the equipment, but also ensures the safety and reliability of the equipment through multiple innovative mechanisms. It effectively solves the problems faced by traditional transformers, such as transportation difficulties, complex installation and pollution risks, and provides a more efficient, safe and economical solution for the production, transportation and installation of transformers.

[0025] See also Figures 1 to 10A transformer for convenient installation of a heat dissipation module comprises a transformer body 11 and a radiator 12, an external disk 41 is coaxially installed on an external tube 22, a fixed disk 42 is coaxially installed on a fixed tube 21, a plurality of connecting bolts 43 are installed between the external disk 41 and the fixed disk 42, at least three groups of radiators 12 are symmetrically installed on both sides of the transformer body 11, the transformer body 11 and the plurality of radiators 12 are filled with insulating heat dissipation oil, a connecting mechanism comprises a fixed tube 21 connected and installed on a side wall of the transformer body 11, an external tube 22 is connected and installed on the radiator 12, a cross sleeve 23 and a fitting disk 24 are respectively installed in the external tube 22 and the fixed tube 21, push rods 25 are respectively slidably connected in the two cross sleeves 23, a follower sleeve 26 is coaxially installed on the push rod 25, a counter sleeve 27 is coaxially arranged near one side of the two follower sleeves 26, and the counter sleeve 27 is coaxially arranged near one side of the two follower sleeves 26. A plurality of expansion grooves 28 are provided at equal intervals on the side wall, and an expansion block 29 is slidably connected in each expansion groove 28. The connection mechanism also includes a one-way groove 210 provided on the two fitting disks 24. A sealing disk 211 is respectively installed on the two follower sleeves 26. When the two opposing sleeves 27 fit together, the sealing disks 211 on both sides are respectively away from the two one-way grooves 210. When the sealing disk 211 fits on the one-way groove 210, the expansion block 29 fits on the fitting disk 24. A tension spring 212 is respectively sleeved on the two push rods 25, one end of the tension spring 212 is fixedly connected to the push rod 25, and the other end of the tension spring 212 is fixedly connected to the cross sleeve 23. Round heads 213 are respectively provided on the plurality of expansion blocks 29. When the external pipe 22 is untied from the connection with the fixed pipe 21, the sealing disk 211 moves toward the fitting disk 24, and the round head 213 abuts against the one-way groove 210.

[0026] When the transformer body 11 and the radiator 12 need to be transported, they need to be disassembled and transported separately to avoid damage to the radiator 12 during transportation. First, loosen the connecting bolts 43. Figure 3 Then, the two external pipes 22 on the corresponding radiator 12 can be pulled out from the fixed pipe 21, and the connection between the two can be released, and then the transformer body 11 and the radiator 12 can be transported separately.

[0027] When the connection between the external tube 22 and the fixed tube 21 is released, the two opposing sleeves 27 are in conflict with each other before release, so the sealing disks 211 and the one-way grooves 210 at both ends are in a released state. At this time, the external tube 22 and the fixed tube 21 are in a connected state, so the heat dissipation oil can flow into the radiator 12 through the transformer body 11 for heat dissipation. When release is required, please refer to Figure 4 and Figure 5First, pull the radiator 12 outward, and then the two external tubes 22 will be pulled outward accordingly, thereby releasing the contact between the two fitting disks 24, and the two opposing sleeves 27 are still in a fitted state at this time. As the distance between the external tube 22 and the fixed tube 21 increases, the tension springs 212 at both ends gradually shrink from the maximum stretched position, and the tension at this time continues to decrease. As the sealing disk 211 approaches the position of the one-way groove 210, the round head 213 passes over the one-way groove 210. At this time, the two-way spring will also apply a thrust to the adjusting rod 32 to ensure that the expansion block 29 is in a contracted state, and then until the sealing disk 211 fits on the one-way groove 210, the one-way grooves 210 on both sides are in a sealed state, so that they are in a sealed state after the connection is released.

[0028] The fixing mechanism includes an internal groove 31 provided in the follower sleeve 26, an adjusting rod 32 is coaxially slidably connected in the internal groove 31, a conical rod 33 is coaxially installed on the adjusting rod 32, and a contraction groove 34 with the same number as the expansion block 29 is evenly spaced on the side wall of the conical rod 33, and a follower ball 35 is respectively installed on each expansion block 29, and the follower ball 35 is slidably connected in the contraction groove 34. The fixing mechanism also includes a return spring 36 fixedly installed on the side of the adjusting rod 32 away from the conical rod 33, and the return spring 36 abuts against the internal groove 31. The inner groove 31 has a limit ring 37 installed in it. When the conical rod 33 is not subjected to force, the adjusting rod 32 abuts against the limit ring 37 under the action of the return spring 36. A bidirectional spring 38 is slidably installed in the opposing sleeve 27. The bidirectional spring 38 and the two opposing sleeves 27 are coaxially arranged. Bidirectional heads 39 are respectively installed on both sides of the bidirectional spring 38. The two bidirectional heads 39 are respectively inserted into the two conical rods 33. When the two opposing sleeves 27 are fitted with each other, both sides of the bidirectional spring 38 also move to the position of the expansion blocks 29 at both ends.

[0029] When the one-way disc is fitted on the one-way groove 210, and the two opposing sleeves 27 are also in a fitted state, continue to pull outwards, see Fig. 9 Number Fig.10 , then the two opposing sleeves 27 are just unfastened and fitted, and the two-way springs 38 are still applying thrust to the adjusting rods 32 on both sides, ensuring that the expansion block 29 is in a contracted state. As it continues to move outward, the elastic force of the two-way spring 38 is less than the elastic force of the return spring 36. At this time, the cone rod 33 will move in the direction of the limit ring 37, and under the action of the contraction groove 34, it will drive the follower ball 35 to expand outward, and at this time, it will drive multiple expansion blocks 29 to expand outward along the expansion groove 28. At this time, the expansion block 29 will be stuck on the fitting disk 24, thereby ensuring the sealing stability between the sealing disk 211 and the one-way groove 210. As the connection between the external rod and the fixed tube 21 is unfastened, the two-way spring 38 can be taken out, thereby completing the unfastening process.

[0030] When it is necessary to fix the insertion, the two-way head 39 is first installed on the opposing sleeve 27 on one side, and then the two-way head 39 is inserted into the opposing sleeve 27 on the other side, at this time, the radiator 12 and the external pipe 22 are driven to move toward the fixed pipe 21, and the pressure provided by the two-way spring 38 causes the cone rod 33 to move backward, and the return spring 36 is compressed. At this time, the follower ball 35 will shrink with the contraction groove 34, so that the multiple expansion blocks 29 will also shrink synchronously with the follower ball 35, and then the expansion block 29 and the fitting are unlocked. The disks 24 are clamped together, and the opposing sleeves 27 fit together. At this time, pressing will cause the tension springs 212 on both sides to be pulled, and the seal between the sealing disk 211 and the one-way groove 210 will be released, so that the connection between the external tube 22 and the fixed tube 21 is released, and then the external tube 22 is completely inserted into the fixed tube 21, so that the external disk 41 and the fixed disk 42 fit together, and then a plurality of connecting bolts 43 are respectively connected to the external disk 41 and the fixed disk 42, thereby completing the sealing state.

[0031] This connection method ensures that the heat sink 12 and the transformer body 11 are connected only when the two are connected. When the connection is disconnected and transported separately, not only the external tube 22 and the fixed tube 21 are in a sealed state, but also the expansion block 29 will be stuck on the fitting disk 24, ensuring the stability of the clamping connection. The seal can only be released when the bidirectional spring 38 is placed in the opposing sleeve 27, thereby ensuring the sealing stability of transportation.

[0032] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
