[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

Figure 3 A cross-sectional view of the air-cooling mechanism in this invention is shown. Figure 4 A schematic diagram of the quick assembly / disassembly mechanism in this utility model is shown.

Figure 6 This is a schematic diagram of the assembly state of the L-shaped steel and the fixing mechanism in this utility model. Figure 7The diagram shows a system framework of the transformer according to this invention. The air-cooling device 200 includes an air-cooling mechanism 1 and multiple quick-assembly / disassembly mechanisms 2. The air-cooling mechanism 1 includes a fan housing 11 and a fan 12, the fan 12 being installed inside the fan housing 11, and the multiple quick-assembly / disassembly mechanisms 2 being installed on the fan housing 11. Each quick-assembly / disassembly mechanism 2 includes an L-shaped steel 21 and a fixing mechanism 22, the fixing mechanism 22 being detachably installed on the L-shaped steel 21, and the L-shaped steel 21 being provided with... The device has multiple fixing slots 211. The fixing mechanism 22 includes a mounting plate 221 and multiple fixing knobs 222 that cooperate with the fixing slots 211. Each fixing knob 222 is rotatably mounted on the mounting plate 221. Each fixing knob 222 has a connecting rod 2221 with a clamping boss 2222 at its bottom. The connecting rod 2221 passes through a fixing slot 211 from the bottom of the fixing knob 222 and rotates under the drive of the fixing knob 222. In this embodiment, the air-cooling device 200 includes an air-cooling mechanism 1 and two quick-assembly mechanisms 2. The two quick-assembly mechanisms 2 are respectively installed on opposite sides of the air-cooling mechanism 1. The air-cooling mechanism 1 is mounted on the mounting channel steel 110 of the transformer 100 based on the two quick-assembly mechanisms 2. The L-shaped steel 21 has four fixing slots 211, and the axes of the four fixing slots 211 are located on the same straight line. The fixing mechanism 22 includes a mounting plate 221 and four fixing knobs 222. The positions of the four fixing knobs 222 correspond to the positions of the four fixing slots 211, that is, the position of one fixing knob 222 corresponds to the position of one fixing slot 211. This ensures that when the fixing mechanism 22 is installed, all four fixing knobs 222 can be simultaneously inserted into the four fixing slots 211 and directly pass through the fixing slots 211 to cooperate with the mounting channel steel 110 of the transformer 100. This avoids inserting the fixing knobs 222 into the fixing slots 211 one by one, reducing alignment time and improving installation efficiency. Furthermore, the fixing mechanism 22 helps the air-cooling device 200 to be directly fixed to the mounting channel steel 110 of the transformer 100, reducing the step of manually pressing and fixing the air-cooling device 200 and improving installation efficiency. The connecting rod 2221 is driven to rotate by the fixing knob 222, that is, the connecting rod 2221 is switched between a locked state and a released state by the rotation of the fixing knob 222. When the connecting rod 2221 is switched to the locked state by the fixing knob 222, the clamping surface of the clamping boss 2222 is perpendicular to the fixing groove 211. That is, only a part of the clamping surface of the clamping boss 2222 overlaps with the fixing groove 211. The clamping boss 2222 and the fixing groove 211 form a cross shape, ensuring that the clamping boss 2222 is engaged with the fixing groove 211, thereby achieving the locking effect.When the connecting rod 2221 is switched to the loose state by the fixing knob 222, the clamping surface of the clamping boss 2222 is parallel to the fixing groove 211, that is, the clamping boss 2222 and the fixing groove 211 are completely overlapped, and the clamping boss 2222 can be directly pulled out from the fixing groove 211. That is, the entire fixing mechanism 22 can be separated from the L-shaped steel 21 and the mounting channel steel 110 of the transformer 100, realizing quick disassembly.

[0019] It should be noted that the air-cooling device 200 is detachably mounted on the mounting channel steel 110 of the transformer 100, and the air outlet of the portable and detachable transformer air-cooling device 200 faces the heat dissipation fins of the transformer 100. In this embodiment, two portable and detachable transformer air-cooling devices 200 are detachably mounted on both sides of the transformer 100, and both portable and detachable transformer air-cooling devices 200 are mounted on the mounting channel steel 110 of the transformer 100, with their air outlets facing the heat dissipation fins of the transformer 100. The two portable and detachable transformer air-cooling devices 200 maintain an appropriate distance and angle from the heat dissipation fins of the transformer 100, so that the airflow generated by the fan can accurately and effectively cover the heat dissipation fins, allowing the airflow to flow evenly and stably over the heat dissipation fins, quickly removing heat, significantly improving heat dissipation efficiency, and reducing the risk of the transformer 100's performance being affected by localized overheating.

[0020] Specifically, when the fixing mechanism 22 needs to install the air-cooling mechanism 1 on the mounting channel steel 110 of the transformer 100, the air-cooling mechanism 1 is placed on the mounting channel steel 110 of the transformer 100. The four fixing knobs 222 of the fixing mechanism 22 are rotated to release the connecting rod 2221. Then, the four fixing knobs 222 of the fixing mechanism 22 are aligned with the four fixing slots 211, and the connecting rod 2221 and the clamping boss 2222 are passed through the L-shaped steel 21 and the mounting channel steel 110, so that the lower end face of the mounting plate 221 abuts against the end face of the L-shaped rod. Then, rotate the fixing knobs 222 one by one to change the connecting rod 2221 from the loose state to the locked state. At this time, the clamping boss 2222 rotates, and the clamping surface of the clamping boss 2222 abuts against the lower end face of the mounting channel steel 110 of the transformer 100. At this time, the clamping surface of the clamping boss 2222 and the lower end face of the mounting plate 221 exert force simultaneously to tightly press the L-shaped steel 21 and the mounting channel steel 110 together, thereby achieving locking. This avoids the need for two people to simultaneously install the air-cooling mechanism 1 and stabilize the air-cooling mechanism 1 in the designated position, reduces the need for manual stabilization of the air-cooling mechanism 1 in the designated position, and improves installation efficiency.

[0021] Conversely, when the fixing mechanism 22 needs to remove the air-cooling mechanism 1 from the mounting channel steel 110 of the transformer 100, the four fixing knobs 222 are turned to release the connecting rod 2221. The clamping surfaces of the four clamping bosses 2222 coincide with the fixing groove 211. The fixing mechanism 22 can be removed by lifting the mounting plate 221, and then the air-cooling mechanism 1 can be removed, achieving quick disassembly.

[0022] Furthermore, the mounting plate 221 is provided with a plurality of mounting holes 2211, each mounting hole 2211 being positioned corresponding to the fixing groove 211, and a fixing knob 222 being rotatably inserted into one of the mounting holes 2211. In this embodiment, the mounting plate 221 is provided with four mounting holes 2211, each mounting hole 2211 being positioned corresponding to the fixing groove 211, such that the connecting rod 2221 at the end of the fixing knob 222 in each mounting hole 2211 can pass through the fixing groove 211, ensuring that the clamping boss 2222 can clamp the mounting plate 221, the L-shaped steel 21, and the mounting channel steel 110 of the transformer 100 together, reducing the risk of the air-cooling device 200 falling off the transformer 100 during use.

[0023] Furthermore, each mounting hole 2211 is provided with a limiting boss 2212, the upper end face of which abuts against the lower end face of the head of the fixing knob 222. In this embodiment, the limiting boss 2212 in each mounting hole 2211 restricts the movement range of the fixing knob 222, preventing the fixing knob 222 from passing through the mounting hole 2211 and directly abutting against the fixing groove 211, thus avoiding repeated friction between the fixing knob 222 and the edge of the mounting hole 2211. This reduces wear at the connection between the fixing knob 222 and the connecting rod 2221, thereby reducing the risk of wear between the fixing knob 222 and the connecting rod 2221 and extending their service life.

[0024] It should be noted that lubricating oil is provided between the inner wall of the mounting hole 2211 and the fixing knob 222. The lubricating oil can reduce the friction between the fixing knob 222 and the inner wall of the mounting hole 2211, and reduce the difficulty of rotating the fixing knob 222.

[0025] Furthermore, the clamping boss 2222 is a triangular clamping boss, and the clamping surface of the triangular clamping boss is connected to the end of the connecting rod 2221. The end of the connecting rod 2221 is located at the center of the clamping surface of the triangular clamping boss. When the triangular clamping boss is driven by the connecting rod 2221 to rotate to the locked state, the clamping surface of the triangular clamping boss abuts against the end face of the transformer 100 mounting channel steel 110, thereby making the transformer 100 mounting channel steel 110, the L-shaped steel 21, and the mounting plate 221 tightly attached to each other. At the same time, the transformer 100 mounting channel steel 110 applies a reaction force to the triangular clamping boss. The reaction force is evenly distributed and transmitted along the three sides of the triangular clamping boss, so that each side can bear a part of the external force and transmit the force to the other sides connected to it, forming a stable force transmission network. This force distribution and transmission method enables the triangular structure to withstand large external forces without damage, avoiding the risk of damage to the triangular clamping boss during use and helping to extend the service life of the clamping boss.

[0026] Furthermore, the fixing mechanism 22 is made of metal, and in this embodiment, the fixing mechanism 22 is preferably made of steel. When the fixing mechanism 22 is made of steel, steel has high tensile strength, which can withstand huge external forces without breaking. In addition, steel has strong fatigue resistance, which makes it less likely to crack or break under repeated loads. This helps to reduce the risk of the fixing mechanism 22 breaking during use and extend the service life of the fixing mechanism 22.

[0027] Furthermore, the fan 12 housing includes multiple first sidewalls 11 and second sidewalls 112, wherein the multiple first sidewalls 11 and second sidewalls 112 are connected end to end to form a receiving cavity for accommodating the fan 12; each of the first sidewalls 11 is provided with multiple ventilation slots 1111, and the multiple ventilation slots 1111 are evenly distributed on the first sidewall 11. In this embodiment, the fan 12 housing includes three first sidewalls 11 and one second sidewall 112, wherein the three first sidewalls 11 are provided with multiple ventilation slots 1111, and the second sidewall 112 is a rectangular plate. The second sidewall 112 blocks the airflow in one direction, preventing some airflow from forming a short circuit inside the fan 12, which helps to reduce ineffective circulation of airflow inside the fan 12 and improve the ventilation effect. Twenty ventilation slots 1111 are provided on any of the first sidewalls 11. The twenty ventilation slots 1111 are evenly distributed on the first sidewalls 11, which facilitates the fan 12 inside the fan 12 housing to evenly discharge airflow, so that the airflow can flow evenly toward the heat dissipation fins of the transformer 100 and carry some heat, thereby accelerating the heat dissipation efficiency of the transformer 100.

[0028] Furthermore, the fan 12 includes a cylindrical impeller 121 and a drive motor 122 connected to one end of the impeller 121; the other end of the impeller 121 is rotatably connected to the top of the fan 12 housing. The cylindrical impeller 121 enables the airflow to form a relatively uniform flow inside the impeller 121. The impeller 121 consists of three blade groups, each with twenty blades, and the blades are backward-curved. This design enables the airflow to form a more stable and uniform flow inside the impeller 121, reducing airflow separation and eddy current generation, thereby reducing noise. The other end of the impeller 121 is rotatably connected to the top of the fan 12 housing, meaning that when the drive motor 122 is working, it can drive the impeller 121 to rotate. Under the guidance of the impeller 121, the air flows according to a predetermined path and speed, avoiding airflow turbulence and deflection, which is beneficial for the fan 12 to discharge a uniform and stable airflow to the heat dissipation fins on the transformer 100. One end of the impeller 121 is connected to the drive motor 122, and the other end of the impeller 121 is rotatably connected to the outer casing of the fan 12. The impeller 121 is fixed from both ends to avoid the impeller 121 from swaying during use, which could lead to the risk of eddy currents or airflow separation. This helps to discharge the airflow evenly, so that the airflow can flow evenly towards the heat dissipation fins of the transformer 100 and carry some heat, thereby accelerating the heat dissipation efficiency of the transformer 100.

[0029] Furthermore, a fixed partition 13 is provided inside the casing of the fan 12. The fixed partition 13 has a fixing hole 131, and the fixed partition 13 is sleeved on the drive motor 122 based on the fixing hole 131. The fixed partition 13 is used to limit the movement range of the drive motor 122, avoiding slight vibrations generated by the drive motor 122 during operation. This prevents the drive motor 122 from moving within the receiving cavity, causing the drive motor 122 to drive the cylindrical impeller 121 to move within the receiving cavity. This helps to ensure a constant gap between the impeller 121 and the casing of the fan 12, allowing the airflow to flow stably according to a preset path and parameters, greatly improving the operational stability of the fan 12, and reducing abnormal vibrations and noise caused by the movement of the drive motor 122.

[0030] Furthermore, the distribution transformer air-cooling device 200 includes a controller 3, which is electrically connected to the fan 12 in the air-cooling mechanism 1. In this embodiment, the controller 3 is connected to an external power source, and the controller is electrically connected to the air-cooling mechanism 1, meaning that the controller 3 transmits sufficient electrical energy to the air-cooling mechanism 1. Simultaneously, the controller 3 can also be used to control the operating state of the air-cooling mechanism 1, ensuring that the air-cooling mechanism 1 operates according to a preset program.

[0031] It should be noted that the transformer 100 is equipped with a thermistor and a current transformer. The thermistor is a PT1000, and the current transformer is a ZEMCT131. The thermistor monitors the internal temperature of the transformer 100, and the current transformer accurately senses current changes to ensure the safe, stable, and efficient operation of the system. The thermistor and the current transformer are signal-connected to the controller 3. The thermistor and the current transformer respectively send the detected data to the controller 3. The controller 3 then controls the start and stop of the air-cooling device 200. At the same time, the built-in processing module of the controller 3 can further calculate key metering data such as active power, reactive power, and power consumption of the air-cooling equipment based on the current and voltage data, and then send them to the external gateway.

[0032] In summary, this utility model, by setting a quick-release mechanism on the distribution transformer air-cooling device and a fixing mechanism on the quick-release mechanism, helps to fix the air-cooling device to the transformer mounting channel steel 110, reducing the steps of manually pressing and fixing the air-cooling device and improving installation efficiency. This utility model also sets multiple fixing knobs, the positions of which correspond to the positions of the fixing slots, that is, one fixing knob position corresponds to one fixing slot position. This ensures that when the fixing mechanism is installed, the fixing knobs can be inserted into the fixing slots simultaneously and directly pass through the fixing slots to cooperate with the transformer mounting channel steel 110, avoiding the need to insert the fixing knobs into the fixing slots one by one, reducing alignment time and improving installation efficiency.

The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
