Description

Technical Field

[0001] This invention relates to the field of substation technology, and in particular to an outdoor prefabricated substation and its installation method. Background Technology

[0002] Substations are core power facilities that transform voltage, distribute electrical energy, and control the direction of power flow. They achieve the conversion and transmission of high and low voltage electricity through transformers, switching equipment, etc. The core connection between substations and outdoor prefabricated substations is that outdoor prefabricated substations are an integrated and modular form of substations, which are suitable for power supply scenarios without building equipment rooms outdoors, directly improving the deployment efficiency of power facilities.

[0003] In existing technologies, some substations prefabricate and integrate core components such as transformers, high and low voltage switchgear, and metering devices into a sealed enclosure. External high-voltage power is first connected to the high-voltage switchgear, and after being controlled by equipment such as disconnecting switches and circuit breakers, it is input to the transformer. The transformer completes the voltage reduction conversion from high voltage to low voltage. The converted low-voltage power is then distributed and protected by the low-voltage switchgear, and then transmitted to the user end through the outgoing circuit. At the same time, the enclosure's sealing, insulation, and lightning protection grounding design ensures stable operation of the equipment in harsh outdoor environments, achieving safe power conversion and accurate power distribution throughout the entire process.

[0004] In practical use, some outdoor prefabricated substations cannot perform reciprocating heat dissipation, which can lead to a chain reaction of problems such as equipment overheating, reduced lifespan, and power supply failures. Reciprocating heat dissipation is the key to ensuring the stable operation of core components such as transformers and switchgear inside the enclosure. Without this function, the heat generated by the equipment cannot be continuously dissipated and form a circulating heat dissipation loop, which can easily accumulate inside the enclosure and form local high temperatures. High temperatures will accelerate the aging of insulation components and reduce the performance of conductive elements, which will not only significantly shorten the service life of the equipment, but also cause faults such as short circuits and tripping.

[0005] Therefore, it is necessary to provide a new type of outdoor prefabricated substation and its installation method to solve the above-mentioned technical problems. Summary of the Invention

The drive rod is rotatably connected inside the mounting blocks.

[0007] Preferably, a pulley assembly is fixedly connected to the outside of the driving rod, and a driven rod is fixedly connected to the other end of the pulley assembly.

[0008] Preferably, the limiting component includes an extension plate and a limiting rod. Fixing blocks are fixedly connected to the left and right sides of the cooling fan. The inside of the fixing blocks is slidably connected to the outside of the limiting rod. The two ends of the limiting rod are fixedly connected to the front and rear sides of the substation body through the extension plate.

[0009] Preferably, the cleaning assembly includes an extension frame, the top end of which is fixedly connected to the bottom end of the cooling fan, and the bottom end of which is fixedly connected to a mounting housing. A telescopic rod is fixedly connected inside the mounting housing, and a return spring is sleeved on the outside of the telescopic rod. A limit plate is fixedly connected to the other end of the telescopic rod, and a cleaning plate is fixedly connected to the outside of the limit plate. Multiple cleaning brushes are fixedly connected to the outside of the cleaning plate.

[0010] Preferably, the limiting plate is slidably connected inside the mounting housing, and the cleaning plate is slidably connected inside the mounting housing.

[0011] Preferably, the disassembly and assembly mechanism includes a mounting frame, which is fixedly connected to the left and right sides of the outside of the mounting base. A connecting shaft is fixedly connected inside the mounting frame, and a rotating plate is rotatably connected to the outside of the connecting shaft. A reset component is fixedly connected to the bottom end of the rotating plate, and a positioning rod is fixedly connected to the top end of the rotating plate. Anti-fall-off components are fixedly connected to the left and right sides of the bottom of the substation body.

[0012] Preferably, the reset assembly includes a second telescopic rod, which is externally fixedly connected to the bottom of the rotating plate, and a mounting spring is sleeved on the outside of the second telescopic rod.

[0013] Preferably, the anti-detachment component includes a limiting rod, the limiting rod is externally slidably connected to the inside of the substation body, a limiting block is slidably connected to the inside of the substation body, and a tension spring is sleeved on the outside of the limiting rod.

[0014] Preferably, one end of the tension spring is fixedly connected to the inside of the substation body, and the other end of the tension spring is fixedly connected to the outside of the limiting block.

[0015] The present invention also provides an installation method for an outdoor prefabricated substation. The installation method includes the following steps: S1: operate the rotating plate in the disassembly and assembly mechanism to make the rotating plate rotate around the connecting shaft; the rotating plate drives the positioning rod to move synchronously, while squeezing the telescopic rod and the installation spring until the positioning rod is separated from the outside of the substation body, so as to reserve space for the substation body. S2: Place the substation body on top of the mounting base and adjust its position to meet the installation requirements; then loosen the rotating plate, and the spring will return to its elastic state, causing the telescopic rod two to rotate in the opposite direction to the rotating plate. The rotating plate will further drive the positioning rod to engage with the corresponding position of the substation body, completing the initial fixation of the body. Then loosen the limit rod, and the tension spring will return to its elastic state, causing the limit block and the limit rod to slide in the opposite direction until the limit rod is locked with the positioning rod, further enhancing the installation stability. S3: Start the dual-head motor. The drive end of the dual-head motor drives the active rod to rotate, and the active rod drives the eccentric wheel to rotate synchronously. The rotation of the eccentric wheel drives the rotating plate to swing. The swing of the rotating plate further drives the sliding plate to slide outside the limit rod. The sliding plate drives the cooling fan to move synchronously. At the same time, the fixed block slides synchronously with the cooling fan outside the limit rod, ensuring that the cooling fan moves smoothly back and forth along the preset trajectory. S4: The cooling fan operates, accelerating airflow inside and outside the enclosure through the heat dissipation holes of the substation body to achieve reciprocating heat dissipation. During the reciprocating movement of the cooling fan, the cleaning components work simultaneously: the cleaning brush moves with the cooling fan and contacts the surface of the heat dissipation holes to clean them; if the cleaning brush encounters an obstruction, the cleaning plate drives the limiting plate to slide inside the mounting housing, squeezing the telescopic rod and the return spring to press the cleaning brush, maintaining the cleaning action while buffering the obstruction force; at the same time, the driving rod continues to rotate, driving the driven rod to rotate synchronously through the pulley set, and the eccentric wheel outside the driven rod drives the corresponding rotating plate and sliding plate to move, so that the cooling fan on the other side can simultaneously carry out reciprocating heat dissipation, further improving the heat dissipation efficiency of the enclosure.

[0016] Compared with related technologies, the outdoor prefabricated substation and its installation method provided by the present invention have the following beneficial effects: This invention achieves efficient heat dissipation from the box by using a reciprocating heat dissipation mechanism driven by a dual-head motor. The dual-head motor drives the active rod and eccentric wheel to rotate, which in turn drives the sliding plate to drive the cooling fan to reciprocate along the limit rod. With the help of the belt pulley group transmission, the fans on both sides reciprocate synchronously, forming a full-range circulating heat dissipation loop.

[0017] This invention uses a cooling fan that moves back and forth to drive a cleaning brush to simultaneously contact and rub against the surface of the heat dissipation holes, thereby removing dust and debris from the holes in real time and preventing blockage that could affect ventilation and heat dissipation. If an obstacle is encountered during the cleaning process, the cleaning plate uses a telescopic rod and a return spring to buffer the resistance force, ensuring that the cleaning action is not interrupted.

[0018] This invention allows for easy release of the positioning mechanism by rotating the rotating plate, enabling quick placement or adjustment of the substation body. A spring-driven positioning lever automatically engages to achieve initial fixation, while a limiting lever further engages the rotating plate, creating a double-locking system. This effectively prevents the substation body from loosening or shifting due to vibrations or wind in outdoor environments. This design eliminates the need for specialized tools during substation installation and disassembly, significantly reducing construction and maintenance time.

[0019] This invention features a fixed block that slides precisely along a limit rod during the reciprocating motion of a cooling fan, ensuring a stable motion trajectory and preventing the fan from deviating and colliding with the housing. The elastic buffer design of the cleaning components reduces mechanical wear and extends the service life of the cleaning parts. The transmission structure of the dual-head motor and pulley group provides stable power and can drive the cooling fan to operate efficiently for a long time, meeting the needs of long-term continuous operation of outdoor prefabricated substations.

It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

[0023] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 3 An outdoor prefabricated substation includes: a mounting base 1, which provides a stable foundation for the substation, distributes the weight of the equipment, and resists the influence of the outdoor environment on the stability of the equipment installation. The top of the mounting base 1 is fixedly connected to the substation body 2. The substation body 2 houses core electrical components such as transformers, circuit breakers, disconnect switches, and instrument transformers, which are electrically connected via copper busbars or cables. The side of the substation body has an openable, sealed door equipped with an observation window and a safety lock for easy inspection and monitoring of the equipment's operating status. A reciprocating heat dissipation mechanism is fixedly connected to the outer wall of the substation body 2. The base 1 is fixedly connected to the left and right sides of the exterior with disassembly and assembly mechanisms. The front and rear walls of the substation body 2 are provided with heat dissipation holes 33. The function of the heat dissipation holes 33 is to build a basic heat dissipation channel to achieve natural ventilation and heat dissipation inside and outside the box. At the same time, the dustproof net and rainproof louvers ensure ventilation and heat dissipation while taking into account outdoor protection. The reciprocating heat dissipation mechanism is assisted to improve the overall heat dissipation efficiency. The top of the substation body 2 is fixedly connected to a protective top cover 32. The function of the protective top cover 32 is to provide the substation with top outdoor protection to resist wind, rain, sun exposure, falling objects and other damage. At the same time, the heat insulation and drainage design ensures the stability of the internal environment of the box. The reciprocating cooling mechanism includes a mounting plate 3. The mounting plate 3 serves as the core mounting reference for the reciprocating cooling mechanism, ensuring a stable connection between the dual-head motor 4 and the substation body 2, and guaranteeing the installation accuracy and operational stability of all components of the cooling mechanism. The mounting plate 3 is fixedly connected to the top of the substation body 2. The dual-head motor 4 is fixedly connected inside the mounting plate 3. The dual-head motor 4 provides a power source for the reciprocating cooling mechanism, achieving synchronous operation of the two-sided transmission mechanisms through a bidirectional drive end, ensuring the coordination and stability of the reciprocating motion of the cooling fan 9. A drive rod 5 is fixedly connected to the drive end of the dual-head motor 4. An eccentric wheel 6 is fixedly connected to the outside of the drive rod 5. A rotating plate 7 is rotatably connected to the outside of the eccentric wheel 6. One end of the rotating plate 7 is rotatably connected to the eccentric wheel 6 via a bearing, and the other end is rotatably connected to the outer top of the sliding plate 8 via a pin, forming a crank-connecting rod mechanism. The bottom end of the rotating plate 7 is rotatably connected to the sliding plate 8. The function of plate 8 is to serve as the mounting carrier for cooling fan 9, transmitting the reciprocating power from rotating plate 7 to cooling fan 9, driving cooling fan 9 to achieve reciprocating motion, and providing a mounting base for fixed block 22. Cooling fan 9 is fixedly connected to the bottom of sliding plate 8. Cooling fan 9 is powered by flexible wear-resistant cable. One end of the cable is connected to the internal power supply terminal of substation body 2, and is laid along the extension plate 19 of limit component with a reserved redundant length. The other end is connected to the fan terminal. Wear-resistant rubber sleeve is fitted at the contact point between the cable and sliding plate 8, which naturally expands and contracts with the reciprocating motion of the fan, ensuring continuous power supply and preventing cable friction damage and pull breakage. The function of cooling fan 9 is to achieve air exchange between the inside and outside of the box through large-volume ventilation, remove the heat generated by the operation of electrical components, and expand the heat dissipation range with reciprocating motion. Multiple limit components are fixedly connected to the front and rear sides of the external exterior of substation body 2. The limit components include extension plate 19 and limit rod 20. See Figures 3 to 5Fixed blocks 22 are fixedly connected to the left and right sides of the cooling fan 9. The inside of the fixed blocks 22 is slidably connected to the outside of the limiting rod 20. The two ends of the limiting rod 20 are fixedly connected to the front and rear sides of the substation body 2 through the extension plate 19. A cleaning component is fixedly connected to the bottom of the cooling fan 9. The cleaning component includes an extension frame 10, which realizes a stable connection between the cleaning component and the cooling fan 9 and drives the cleaning component to move synchronously with the cooling fan 9. The top of the extension frame 10 is fixedly connected to the bottom of the cooling fan 9. A mounting housing 11 is fixedly connected to the bottom of the extension frame 10. A telescopic rod 12 is fixedly connected inside the mounting housing 11 to provide elastic support for the cleaning plate 15. The telescopic rod 12 is fitted with a return spring 13. In the initial state, it is in a naturally extended state. When the cleaning brush 16 contacts the heat dissipation hole 33, the spring is compressed to generate elastic force, so that the cleaning brush 16 fits tightly against the dustproof net. The other end of the telescopic rod 12 is fixedly connected to a limit plate 14. A cleaning plate 15 is fixedly connected to the outside of the limit plate 14. Multiple cleaning brushes 16 are fixedly connected to the outside of the cleaning plate 15. When the cooling fan 9 drives the cleaning component to reciprocate, the cleaning brushes 16 fit tightly against the dustproof net under the elastic action of the return spring 13, and sweep the dust attached to the dustproof net, so as to achieve real-time cleaning of the heat dissipation hole 33. Mounting blocks 21 are fixedly connected to the top four corners of the substation body 2. The external rotatable connection of the active rod 5 is connected to the inside of the mounting block 21. The external fixed connection of the active rod 5 is a pulley assembly 17, which consists of an active pulley, a driven pulley, and a synchronous belt. The active pulley is fixed to the outside of the active rod 5, and the driven pulley is fixed to the outside of the driven rod 18, ensuring that the active rod 5 and the driven rod 18 rotate synchronously, thereby realizing the synchronous movement of the two eccentric wheels 6. The other end of the pulley assembly 17 is fixedly connected to the driven rod 18. The driven rod 18 is linked with the active rod 5 through the pulley assembly 17, transmitting the power of the active rod 5 to the eccentric wheel 6 on the side away from the motor, realizing the synchronous rotation of the two eccentric wheels 6, and ensuring the smoothness of the reciprocating motion of the cooling fan 9. The external fixed connection of the eccentric wheel 6 is to the front and rear sides of the driven rod 18. The external sliding connection of the limiting plate 14 is to the inside of the mounting housing 11, and the external sliding connection of the cleaning plate 15 is to the inside of the mounting housing 11.

[0025] See Figures 4 to 6The disassembly and assembly mechanism includes a mounting bracket 23. The mounting bracket 23 serves as the core mounting reference for the disassembly and assembly mechanism, ensuring a stable connection between the mechanism and the mounting base 1. It provides precise installation support for components such as the connecting shaft 24 and the rotating clamping plate 25, ensuring the operational stability and reliability of the disassembly and assembly mechanism. The mounting bracket 23 is externally fixedly connected to the left and right sides of the mounting base 1. Internally, the mounting bracket 23 is fixedly connected to the connecting shaft 24. The connecting shaft 24 provides stable rotational support for the rotating clamping plate 25, enabling flexible rotation of the plate while simultaneously restricting its movement. The axial displacement is achieved by rotating a plate 25 externally connected to the connecting shaft 24. The rotating plate 25 serves as the core transmission component of the disassembly and assembly mechanism. Through the lever principle, it transmits the elastic force of the reset component to the positioning rod 28, thereby achieving automatic locking and unlocking of the positioning rod 28 and ensuring the rapid positioning connection between the substation body 2 and the mounting base 1. A reset component is fixedly connected to the bottom external end of the rotating plate 25. The reset component includes a telescopic rod 26, which is externally fixedly connected to the bottom external end of the rotating plate 25. A mounting spring 27 is sleeved on the outside of the telescopic rod 26. See Figures 5 to 7 The function of the reset component is to provide elastic reset power for the rotating plate 25, ensuring that the positioning rod 28 can stably clamp the substation body 2, achieving rapid positioning and installation; at the same time, the elastic structure facilitates the unlocking operation during disassembly, improving the convenience of disassembly and assembly, and ensuring the stable and reliable operation of the disassembly and assembly mechanism. The external top of the rotating plate 25 is fixedly connected to the positioning rod 28. The function of the positioning rod 28 is to achieve precise positioning and clamping between the substation body 2 and the mounting base 1, ensuring a stable connection between the two after installation and preventing equipment displacement caused by environmental factors such as strong outdoor winds. The left and right sides of the external bottom of the substation body 2 are fixedly connected to anti-detachment components. The anti-detachment components include a limit rod 29. The external limit rod 29 is slidably connected to the inside of the substation body 2. The inside of the substation body 2 is slidably connected to a limit block 30. A tension spring 31 is sleeved on the outside of the limit rod 29. One end of the tension spring 31 is fixedly connected to the inside of the substation body 2, and the other end of the tension spring 31 is fixedly connected to the outside of the limit block 30.

[0026] An installation method includes the following steps: S1: Operate the rotating plate 25 in the disassembly and assembly mechanism to make the rotating plate 25 rotate around the connecting shaft 24; the rotating plate 25 drives the positioning rod 28 to move synchronously, while squeezing the telescopic rod 26 and the installation spring 27 until the positioning rod 28 is separated from the outside of the substation body 2, so as to reserve space for the substation body 2. S2: Place the substation body 2 on top of the mounting base 1 and adjust the position of the substation body 2 to meet the installation adaptation requirements; then loosen the rotating clamp 25, and the installation spring 27 elastically resets, causing the telescopic rod 26 to rotate in the opposite direction to the rotating clamp 25. The rotating clamp 25 further drives the positioning clamp 28 to engage in the corresponding position of the substation body 2, completing the initial fixation of the body. Then loosen the limit clamp 29, and the tension spring 31 resets, causing the limit block 30 to slide in the opposite direction to the limit clamp 29 until the outside of the limit clamp 29 is locked with the positioning clamp 28, thereby further enhancing the installation stability. S3: Start the dual-head motor 4. The drive end of the dual-head motor 4 drives the active rod 5 to rotate, and the active rod 5 drives the eccentric wheel 6 to rotate synchronously. The rotation of the eccentric wheel 6 drives the rotating plate 7 to swing. The swing of the rotating plate 7 further drives the sliding plate 8 to slide outside the limit rod 20. The sliding plate 8 drives the cooling fan 9 to move synchronously. At the same time, the fixed block 22 slides synchronously with the cooling fan 9 outside the limit rod 20, ensuring that the cooling fan 9 moves smoothly back and forth along the preset trajectory. S4: The cooling fan 9 operates, accelerating the airflow inside and outside the enclosure through the heat dissipation holes 33 of the substation body 2, achieving reciprocating heat dissipation. During the reciprocating movement of the cooling fan 9, the cleaning components work simultaneously: the cleaning brush 16 moves with the cooling fan 9 and contacts the surface of the heat dissipation holes 33 to clean them. If the cleaning brush 16 encounters an obstruction, the cleaning plate 15 drives the limiting plate 14 to slide inside the mounting housing 11, squeezing the telescopic rod 12 and the return spring 13 to squeeze the cleaning brush 16, maintaining the cleaning action while buffering the obstruction. At the same time, the driving rod 5 continues to rotate, driving the driven rod 18 to rotate synchronously through the pulley group 17. The eccentric wheel 6 outside the driven rod 18 drives the corresponding rotating plate 7 and sliding plate 8 to move, so that the cooling fan 9 on the other side can simultaneously carry out reciprocating heat dissipation, further improving the heat dissipation efficiency of the enclosure.

[0027] The working principle of the outdoor prefabricated substation and its installation method provided by this invention is as follows: First, by operating the rotating plate 25 in the disassembly and assembly mechanism, the rotating plate 25 is rotated outside the connecting shaft 24. The rotating plate 25 drives the positioning rod 28 to move synchronously, while simultaneously pressing the telescopic rod 26 and the mounting spring 27 to retract them. At this time, the positioning rod 28 is in the retracted state. The substation body 2 is placed on top of the mounting base 1, and its position is adjusted to meet the installation requirements. Then, the rotating plate 25 is released, and the mounting spring 27 returns to its original position, causing the telescopic rod 26 and the rotating plate 25 to rotate in opposite directions. The rotating plate 25 drives the positioning rod 28 to retract. Positioning lever 28 is inserted into the corresponding slot in the substation body 2 to complete the initial fixation. The limiting lever 29 in the anti-detachment component is operated to pull the limiting lever 29 so that it slides inside the substation body 2. The limiting lever 29 drives the limiting block 30 to move synchronously, compressing the tension spring 31 to contract it. Then the limiting lever 29 is released, and the tension spring 31 resets, causing the limiting block 30 and the limiting lever 29 to slide in opposite directions until the outside of the limiting lever 29 is locked with the rotating plate 25, further enhancing the installation stability of the substation body 2.

[0028] The dual-head motor 4 is started. The drive end of the dual-head motor 4 drives the active rod 5 to rotate. The active rod 5 drives the eccentric wheel 6 to rotate synchronously. The rotation of the eccentric wheel 6 causes the rotating plate 7 to swing. The swing of the rotating plate 7 further drives the sliding plate 8 to slide outside the limit rod 20. The sliding of the sliding plate 8 causes the cooling fan 9 to move synchronously. At the same time, the fixed block 22 slides with the cooling fan 9 outside the limit rod 20, ensuring that the cooling fan 9 reciprocates along the preset trajectory. When the cooling fan 9 is running, it accelerates the air circulation inside and outside the box through the heat dissipation holes 33 of the substation body 2 to achieve reciprocating heat dissipation. During the reciprocating movement of the cooling fan 9, the cleaning group... Synchronous operation: The cleaning brush 16 moves with the cooling fan 9 and contacts the surface of the heat dissipation hole 33 to clean the heat dissipation hole 33. If the cleaning brush 16 encounters an obstruction, the cleaning plate 15 drives the limiting plate 14 to slide inside the mounting housing 11, squeezing the telescopic rod 12 and the return spring 13 to retract it, buffering the obstruction while maintaining the cleaning action. When the driving rod 5 continues to rotate, the pulley group 17 drives the driven rod 18 to rotate synchronously. The eccentric wheel 6 outside the driven rod 18 drives the corresponding rotating plate 7 and sliding plate 8 to move, so that the cooling fan 9 on the other side also performs reciprocating heat dissipation synchronously, further improving the heat dissipation efficiency of the cabinet.

An outdoor prefabricated substation according to claim 6, characterized in that, The reset assembly includes a telescopic rod two (26), which is externally fixedly connected to the bottom of the rotating plate (25), and a mounting spring (27) is sleeved on the outside of the telescopic rod two (26).

8. An outdoor prefabricated substation according to claim 6, characterized in that, The anti-detachment component includes a limiting rod (29), the external part of which is slidably connected to the inside of the substation body (2), the internal part of which is slidably connected to a limiting block (30), and the external part of which is fitted with a tension spring (31).

9. An outdoor prefabricated substation according to claim 8, characterized in that, One end of the tension spring (31) is fixedly connected to the inside of the substation body (2), and the other end of the tension spring (31) is fixedly connected to the outside of the limiting block (30).

10. An installation method for an outdoor prefabricated substation, used in the substation described in claim 9, characterized in that, S1: Operate the rotating plate (25) in the disassembly and assembly mechanism to make the rotating plate (25) rotate around the connecting shaft (24); the rotating plate (25) drives the positioning rod (28) to move synchronously, and at the same time squeezes the telescopic rod (26) and the installation spring (27) until the positioning rod (28) is separated from the outside of the substation body (2) to reserve space for the substation body (2); S2: Place the substation body (2) on top of the mounting base (1) and adjust the position of the substation body (2) to meet the installation adaptation requirements; then loosen the rotating plate (25), and the installation spring (27) elastically resets, causing the telescopic rod (26) to rotate in the opposite direction to the rotating plate (25). The rotating plate (25) further drives the positioning rod (28) to be inserted into the corresponding position of the substation body (2), completing the initial fixation of the body. Then loosen the limit rod (29), and the tension spring (31) resets, causing the limit block (30) to slide in the opposite direction to the limit rod (29) until the outside of the limit rod (29) is locked with the positioning rod (28), thereby further enhancing the installation stability. S3: Start the dual-head motor (4). The drive end of the dual-head motor (4) drives the active rod (5) to rotate. The active rod (5) drives the eccentric wheel (6) to rotate synchronously. The rotation of the eccentric wheel (6) drives the rotating plate (7) to swing. The swing of the rotating plate (7) further drives the sliding plate (8) to slide outside the limit rod (20). The sliding plate (8) drives the cooling fan (9) to move synchronously. At the same time, the fixed block (22) slides synchronously outside the limit rod (20) with the cooling fan (9) to ensure that the cooling fan (9) moves smoothly back and forth along the preset trajectory. S4: The cooling fan (9) runs and accelerates the air circulation inside and outside the box through the heat dissipation holes (33) of the substation body (2) to achieve reciprocating heat dissipation; during the reciprocating movement of the cooling fan (9), the cleaning components work simultaneously: the cleaning brush (16) moves with the cooling fan (9) and contacts the surface of the heat dissipation hole (33) to clean the heat dissipation hole (33); if the cleaning brush (16) encounters an obstacle, the cleaning plate (15) drives the limiting plate (14) to slide inside the mounting housing (11), squeezing the telescopic rod (12) and the return spring (13) to squeeze the cleaning brush (16), maintaining the cleaning action while buffering the obstruction force; at the same time, the active rod (5) continues to rotate and drives the driven rod (18) to rotate synchronously through the pulley group (17), and the eccentric wheel (6) outside the driven rod (18) drives the corresponding rotating plate (7) and sliding plate (8) to move, so that the cooling fan (9) on the other side can carry out reciprocating heat dissipation synchronously, further improving the heat dissipation efficiency of the box.
