The lower end of the connecting rod passes through the moving groove and extends to the lower outer side of the first outer frame.

[0009] A further improvement of this utility model is that: a support base is fixedly connected to the lower end of both sides of the box body, and an electric push rod is fixedly connected to the surface of the support base. The output end of the electric push rod is rotatably connected to the lower end of the connecting rod.

[0010] A further improvement of the present invention is that the cleaning component includes a servo motor, the output shaft of the servo motor extends into the housing and is fixedly connected to a half gear, and the upper and lower opposing surfaces of the rear end of the housing are rotatably connected to a threaded rod, and the lower end surface of the threaded rod is fixed with a bevel gear one and a bevel gear two on both sides near the half gear, and the outer surfaces of the bevel gear one and the bevel gear two are intermittently meshed with the half gear.

[0015] 1. This utility model uses an adjustable louver's electric push rod, whose output end drives a connecting rod to rotate the opening and closing blades to adjust the angle. This effectively solves the problem that the heat dissipation efficiency of traditional prefabricated substations using fixed louvers or natural ventilation is greatly affected by the external environment. In high-temperature scenarios, the electric push rod can control the opening and closing blades to increase the opening angle, improve the air circulation efficiency inside and outside the box, and quickly dissipate the heat generated by the equipment operation, avoiding equipment tripping, insulation aging, and other faults caused by excessive temperature inside the box. In low-temperature or dusty conditions, the blade opening angle can be reduced to reduce heat loss inside the box, greatly improving the flexibility and stability of heat dissipation in prefabricated substations.

[0016] 2. This utility model utilizes a servo motor in the cleaning assembly to drive a half-gear to intermittently mesh with a bevel gear one and a bevel gear two, causing the threaded rod to rotate forward and backward. This causes the threaded U-shaped cleaning frame to move up and down along the limiting rod, and the brush heads on both sides can automatically clean the dustproof nets on both sides inside the housing. At the same time, the exhaust fan in the dust collection assembly uses a suction pipe, connecting pipe, and suction hose to draw dust raised during the cleaning process into the suction chamber through the suction holes on the U-shaped cleaning frame, and then into the filter box for filtration and collection. This effectively solves the problems of traditional box-type substation dustproof nets requiring manual disassembly and cleaning periodically, which is time-consuming and labor-intensive, and requires power outages during maintenance, affecting the continuity of power supply. It also addresses the problem of dust accelerating the wear and aging of equipment components due to untimely cleaning, thus extending the service life of the equipment. Attached Figure Description

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-2This utility model provides a technical solution: a box-type substation with heat dissipation louvers, including a box body 1, adjustable louvers 2 fixedly connected to both sides of the box body 1, a dust collection assembly 6 fixedly connected to the rear surface of the box body 1, a cleaning assembly 7 fixedly connected to the interior of the box body 1, support columns 8 fixedly connected to the four corners of the upper surface of the box body 1, rain shields 5 fixedly connected to the upper surface of the support columns 8, and a side door 3 rotatably connected to the front surface of the box body 1. The adjustable louvers 2 include a first outer frame 21. The outer surface of the first outer frame 21 is fixedly connected to the second outer frame 22. The inner wall of the second outer frame 22 has several opening and closing blades 23 that rotate relative to each other. These blades 23 are evenly distributed vertically. Movable cavities are formed on the inner walls of the first outer frame 21 and the second outer frame 22 near the opening and closing blades 23. A connecting rod 27 is rotatably connected to the rear end surface of each opening and closing blade 23. A through moving groove 26 is formed on the lower surface of the inner wall of the first outer frame 21, and the lower end of the connecting rod 27 passes through the moving groove 26. 6 extends to the lower outer side of the first outer frame 21. Support seats 24 are fixedly connected to the lower ends of both sides of the box 1. Electric push rods 25 are fixedly connected to the surface of the support seats 24. The output end of the electric push rod 25 is rotatably connected to the lower end of the connecting rod. The opening and closing angle of the adjustable louvers 2 can be adjusted by the electric push rod 25 to achieve the best heat dissipation effect. When the temperature inside the box 1 is high, the electric push rod 25 fixed on the support seat 24 is activated. The output end of the electric push rod 25 pulls the lower end of the connecting rod 27 downward along the through moving groove 26. The connecting rod 27 drives the opening and closing blades 23 to rotate around its rotation axis, which increases the gap between the opening and closing blades 23, increases the air circulation inside and outside the box 1, and accelerates heat dissipation. When the temperature inside the box 1 is low or there is a lot of dust in the outside environment, the output end of the electric push rod 25 pushes the lower end of the connecting rod 27 upward, which drives the opening and closing blades 23 to rotate, reducing the gap between the opening and closing blades 23. This ensures a certain heat dissipation requirement and reduces the amount of dust entering the box 1.

[0025] Reference Figure 4 , Figure 5The cleaning component 7 includes a servo motor 71. The output shaft of the servo motor 71 extends into the housing 1 and is fixedly connected to a half gear 75. A threaded rod 72 is rotatably connected to the upper and lower opposing surfaces of the rear end of the housing 1. A bevel gear 73 and a bevel gear 74 are fixedly attached to the lower end surface of the threaded rod 72 near the upper and lower sides of the half gear 75. The outer surfaces of the bevel gear 73 and the bevel gear 74 intermittently mesh with the half gear 75. Dustproof nets 10 are fixedly connected to the inner sides of the inner sides of the housing 1 near the first outer frame 21. A U-shaped cleaning frame 76 is threadedly connected to the surface of the threaded rod 72. Several brush heads 77 are fixedly connected to the two sides of the U-shaped cleaning frame 76 near the dustproof net 10. Multiple suction holes 79 are opened on the two sides of the U-shaped cleaning frame 76. Suction chambers 7 are opened on the inner walls of the two sides of the U-shaped cleaning frame 76. 8. The two rear ends of the U-shaped cleaning frame 76 are fixedly connected to the outer side of the suction chamber 78. After being started by the servo motor 71, the half gear 75 is driven to rotate. When the half gear 75 meshes with the bevel gear 73 at the lower end of the threaded rod 72, the threaded rod 72 is driven to rotate forward. The U-shaped cleaning frame on the surface of the threaded rod 72 moves downward along the threaded rod 72 under the restriction of the limit rod 12. The brush heads 77 on both sides of the U-shaped cleaning frame clean the surface of the dustproof net 10 and sweep off the dust. When the half gear 75 rotates to mesh with the bevel gear 74, the threaded rod 72 is driven to rotate in reverse. The U-shaped cleaning frame moves upward along the threaded rod 72, and the brush heads 77 clean the surface of the dustproof net 10 again. This cycle is repeated to achieve a comprehensive cleaning of the dustproof net 10 and prevent the dustproof net 10 from being blocked by dust, thus affecting the heat dissipation and ventilation effect.

[0026] Reference Figure 3 The dust collection component 6 includes a support plate 61, a filter box 62 fixedly connected to the surface of the support plate 61, an exhaust fan 64 fixedly connected to the upper surface of the filter box 62, a suction pipe 63 fixedly connected to the input end of the exhaust fan 64, and the other end of the suction pipe 63 extending into the interior of the filter box 62. Connecting pipes 65 are fixedly connected to both sides of the filter box 62, and the other end of the connecting pipes 65 extends into the interior of the box 1 and is fixedly connected to the other end of the suction hose 11. After the exhaust fan 64 is started, a negative pressure is formed inside the filter box 62 through the suction pipe 63, so that the air inside the box 1 carries dust and dust brushed off during cleaning and is sucked into the suction chamber 78 of the U-shaped cleaning rack 76 through the suction hole 79, and then enters the filter box 62 through the suction hose 11 and the connecting pipe 65. The filter material inside the filter box 62 filters the dust in the air, and the filtered clean air is discharged through the exhaust fan 64, effectively reducing the accumulation of dust in the box 1 and providing a clean operating environment for the equipment inside the box.

[0027] Reference Figure 2 , Figure 5Limiting rods 12 are fixedly connected to both ends of the inner surface of the box 1. The upper end of the limiting rod 12 passes through both ends of the U-shaped cleaning rack 76 and is fixedly connected to the upper inner surface of the box 1. A handle 4 is fixedly connected to the surface of the side door 3. A viewing window is opened at the upper end of the side door 3. Several water drains 9 are opened on the surface of the rain cover 5. The movement trajectory of the U-shaped cleaning rack can be restricted by the limiting rod 12 to prevent deviation. The staff can observe the operation of the equipment in the box 1 through the viewing window at the upper end of the side door 3. When it is necessary to inspect or maintain the equipment in the box, the side door 3 can be opened by pulling the handle 4 on the surface of the side door 3. The rain cover 5 can block rainwater and guide the rainwater to both sides through the water drains 9.

[0028] The working principle and usage process of this utility model are as follows: The optimal heat dissipation effect is achieved by adjusting the opening and closing angle of the adjustable louver 2 using an electric push rod 25. When the temperature inside the housing 1 is high, the electric push rod 25 on the control support 24 is activated. The output end of the electric push rod 25 pulls the lower end of the connecting rod 27 downwards along the through-moving groove 26. The connecting rod 27 drives the opening and closing blades 23 to rotate around its rotation axis, increasing the gap between the opening and closing blades 23, increasing the airflow inside and outside the housing 1, and accelerating heat dissipation. When the temperature inside the housing 1 is high... When the internal temperature is low or the external environment is dusty, the output end of the control electric push rod 25 pushes the lower end of the connecting rod 27 upward, causing the opening and closing blades 23 to rotate, reducing the gap between the opening and closing blades 23. This ensures a certain amount of heat dissipation while reducing dust entering the housing 1. The servo motor 71 of the cleaning component 7 starts its output shaft end, driving the half gear 75 to rotate. The half gear 75 intermittently meshes with the bevel gear 1 73 and bevel gear 2 74 at the lower end of the threaded rod 72, thereby driving the threaded rod 72 to rotate forward or backward. The rotation causes the U-shaped cleaning frame on the surface of the threaded rod 72 to move up and down along the threaded rod 72 under the restriction of the limiting rod 12. The brush heads 77 on both sides of the U-shaped cleaning frame clean the surface of the dustproof net 10, sweeping off the dust. At the same time, after the exhaust fan 64 of the dust collection component 6 is started, a negative pressure is formed inside the filter box 62 through the suction pipe 63, so that the air inside the box 1 carries the dust and the dust brushed off during cleaning, and enters the suction chamber 78 through the suction hole 79, and then through the suction hose 11 and connecting pipe 65. Upon entering the filter box 62, the filter material inside the filter box 62 filters the dust in the air. The filtered clean air is discharged through the exhaust fan 64, effectively reducing the accumulation of dust in the box 1. The rain cover 5 fixed on the upper surface can block rainwater. Rainwater is guided to both sides through the drain trough 9 to prevent rainwater from entering the box 1. The staff can observe the operation of the equipment in the box 1 through the viewing window. When it is necessary to inspect or maintain the equipment in the box, the side door 3 can be opened by pulling the handle 4.
