Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and more particularly to an outdoor power distribution cabinet with a protective structure. Background Technology

[0002] An outdoor power distribution cabinet is a power distribution and control device installed in an outdoor environment. It is a metal cabinet installed in factories, office buildings, residential areas, or outdoors. Its core function is to receive electrical energy from the main power source and then safely and orderly distribute it to various branch circuits to supply different electrical equipment such as machines, lighting, and sockets.

[0003] Fire safety is a primary concern during the operation of traditional power distribution cabinets. Currently, most common power distribution cabinets use fixed temperature sensors at key locations for overheat monitoring. This method struggles to cover all electrical components, easily overlooking potentially heat-generating areas and creating significant blind spots. Furthermore, ventilation openings are typically installed within the cabinet to ensure heat dissipation, but this allows dust, insects, and other contaminants to easily enter. These impurities adhere to the surfaces of electrical components, forming an insulating layer that hinders heat dissipation, causing equipment temperatures to rise and potentially leading to electrical faults such as creepage and short circuits, and in severe cases, even fires. Therefore, to address these issues, an outdoor power distribution cabinet with a protective structure is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an outdoor power distribution cabinet with a protective structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An outdoor power distribution cabinet with a protective structure includes a cabinet body and a cooling fan installed at the center of its bottom. Symmetrically mounted electrical component mounting plates are arranged on the inner side of the cabinet body. A monitoring component is arranged between the two electrical component mounting plates. The monitoring component includes a sliding rail that moves vertically between the two electrical component mounting plates. A horizontally sliding bearing bracket is mounted on the sliding rail. Temperature monitoring heads are symmetrically rotated on the horizontally sliding bearing bracket. The two temperature monitoring heads are 180° out of phase. The temperature monitoring heads are used to monitor the electrical components on the electrical component mounting plates.

[0007] A dustproof assembly is provided on the outer side of the two electrical component mounting plates. The dustproof assembly includes a dustproof cloth, which is retracted and unfolded on the outer side of the two electrical component mounting plates.

The first and second threaded rods are threadedly connected to a movable slide rail. The movable slide rail is slidably arranged on the inner side of the two U-shaped guide plates.

[0014] The two ends of the movable slide rail are respectively fixedly connected to a second bearing seat and a first bearing seat. A first driving bevel gear is rotatably connected to the second bearing seat and engages with and slides with a vertical limiting groove. A first driven bevel gear meshes with the first driving bevel gear. A transverse threaded rod is rotatably connected between the second bearing seat and the first bearing seat. A horizontal limiting groove is symmetrically opened on the transverse threaded rod. The transverse threaded rod is fixedly connected to the first driven bevel gear. The horizontal movable bearing bracket is threadedly connected to the transverse threaded rod.

[0015] The inner side of the horizontal moving bearing bracket is rotatably connected to a second active bevel gear that engages with a horizontal limiting slide groove. A second driven bevel gear meshes with the second active bevel gear. The inner side of the horizontal moving bearing bracket is rotatably connected to a monitoring transmission shaft that is fixedly connected to the second driven bevel gear. A monitoring bevel gear is fixedly connected to the outer side of the monitoring transmission shaft. Driven half-angle gears are symmetrically arranged on the outer side of the monitoring bevel gear. Only one driven half-angle gear meshes with the monitoring bevel gear at a time. The two driven half-angle gears are fixedly connected to a connecting rod. The two temperature monitoring heads are respectively fixedly connected to the two ends of the connecting rod.

[0016] The dustproof component also includes electric guide rails fixedly installed on the bottom and top of the cabinet interior. Multiple limiting posts are provided on the inner side of each of the two electric guide rails. The limiting posts are fixedly connected to the cabinet. A guide rail motor is installed on the electric guide rail. An installation strip is fixedly connected between the two guide rail motors. A cloth tube is fixedly installed on the inner side of the cabinet. An adhesive plate is fixedly connected to the outer side of the cloth tube. A take-up and release shaft is rotatably connected to the inner side of the cloth tube. The dustproof cloth is wrapped around the outer side of the take-up and release shaft, and one end is fixedly connected to it. The other end of the dustproof cloth is fixedly connected to the installation strip.

[0017] A dustproof motor is fixedly installed on the top of the cabinet and is connected to the retraction shaft. A dustproof drive gear is also fixedly connected to the output end of the dustproof motor. A dust cylinder is fixedly connected to the cabinet on the inner side of the dustproof cloth. A cleaning shaft is rotatably connected to the inner side of the dust cylinder. The cleaning shaft is fixedly connected to the cleaning roller. The cleaning shaft is in contact with the inner side of the dustproof cloth. The dust cylinder is fixedly connected to the scraper.

The telescopic end of the electric telescopic rod is rotatably connected to the push plate. The cleaning brush is in contact with the outer side of the dustproof cloth.

[0019] The present invention has the following beneficial effects:

[0020] 1. In this invention, the monitoring component enables two temperature monitoring heads to work alternately with a phase difference of 180°, achieving periodic temperature scanning monitoring of all electrical components on the electrical component mounting board without blind spots. This can promptly detect potential local overheating hazards and greatly improve fire early warning capabilities.

[0021] 2. In this invention, the dustproof component enables the flexible dustproof cloth to quickly unfold and form an arc-shaped barrier that wraps around the electrical component mounting plate, effectively blocking dust. During the dustproof cloth's unfolding and retraction, a scraper continuously scrapes away the dust adsorbed on its inner side into the dust cylinder. Combined with a cleaning brush that sweeps the outer side of the dustproof cloth, a collaborative cleaning mechanism ensures the dustproof cloth's lasting cleanliness and efficient protection.

[0022] 3. In this invention, a sealed motor drives a crankshaft and a drive rod to drive multiple window blades linked by a connecting plate to rotate synchronously and adjust their angles, thereby achieving controllable changes in the opening of the exhaust vent. The waterproof mesh fixed between the window blades can effectively intercept fog and water droplets, and its tilt angle changes can optimize the anti-fog and drainage effects, enabling the cabinet to adapt to the ventilation and protection needs under different weather conditions.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figures 1-15As shown, the present invention proposes an outdoor power distribution cabinet with a protective structure, including a cabinet body 1 and a heat dissipation fan 13 installed at the center of its bottom. Symmetrically mounted electrical component mounting plates 14 are arranged on the inner side of the cabinet body 1. A monitoring component is arranged between the two electrical component mounting plates 14. The monitoring component includes a sliding rail 45, which is vertically movable between the two electrical component mounting plates 14. A horizontally sliding bearing bracket 411 is horizontally slidably mounted on the sliding rail 45. Temperature monitoring heads 412 are symmetrically rotated on the horizontally sliding bearing bracket 411. The two temperature monitoring heads 412 are 180° out of phase. The temperature monitoring heads 412 are used to monitor the electrical components on the electrical component mounting plates 14.

[0042] Dustproof components are provided on the outer side of the two electrical component mounting plates 14. The dustproof components include a dustproof cloth 35. The dustproof cloth 35 is retracted and disposed on the outer side of the two electrical component mounting plates 14. A cleaning brush 39 is provided on the outer side of the dustproof cloth 35 and is in intermittent contact with it. A cleaning roller 311 is rotatably disposed on the inner side of the dustproof cloth 35. A scraper 316 is provided on the outer wall of the cleaning roller 311. The cleaning brush 39 and the cleaning roller 311 are used to clean the dustproof cloth 35.

[0043] The cabinet 1 is equipped with an anti-fog ventilation component, which includes two sets of window slats 2. Multiple waterproof meshes 21 are fixedly connected between two adjacent window slats 2. The waterproof meshes 21 are used to capture fog.

[0044] Example 2

[0045] like Figures 1-2 As shown, based on Embodiment 1, in this embodiment, the top of the cabinet 1 is fixedly connected to the rain roof 10 and the gearbox 12, the bottom of the cabinet 1 is fixedly installed on the base 11, the two sides of the cabinet 1 are provided with exhaust vents 16, the bottom of the inner side of the cabinet 1 is symmetrically fixedly installed with I-shaped plates 15, and two electrical component mounting plates 14 are fixedly installed together with the two I-shaped plates 15.

[0046] In fact, during the actual wiring process, the staff should ensure the sealing of the wiring port on the cabinet 1. The cabinet 1 is also equipped with a cabinet door. The base 11 is a concrete base with a design height of 80cm. The two I-shaped plates 15 on the bottom inner side of the cabinet 1 provide support and fixation for the two electrical component mounting plates 14. Various electrical components are installed on the electrical component mounting plates 14. The cooling fan 13 is installed at the bottom of the cabinet 1 and is located between the two electrical component mounting plates 14. The rain roof 10 is used to shield the entire cabinet 1 from rain. The gearbox 12 contains the monitoring motor 4, monitoring sprocket 41, monitoring chain 42, dustproof motor 31, dustproof drive gear 32 and dustproof driven gear 33. The exhaust vents 16 on both sides of the cabinet 1 work together with the cooling fan 13 installed at the bottom center. When the cooling fan 13 is started, it pushes the hot air inside the cabinet 1 from the top down to form an airflow, which is discharged from the bottom of the cabinet 1, thereby achieving effective forced ventilation and heat dissipation and reducing the temperature rise of the electrical components inside the cabinet due to long-term operation.

[0047] Furthermore, the phase difference between the electrical component mounting plate 14 and the exhaust port 16 is 45°. When the airflow reaches the area of ​​the electrical component mounting plate 14, its flow path changes. Part of the airflow blows directly onto the front of the electrical component mounting plate 14 to cool the electrical components mounted on it. The other part of the airflow dissipates heat to the back of the components due to the separation effect caused by the phase difference.

[0048] Example 3

[0049] like Figures 3-5 , Figure 15 As shown, based on the above embodiments, in this embodiment, the anti-fog ventilation component also includes a sealing motor 28 symmetrically and fixedly connected to the bottom of the cabinet 1. A crank disk 22 is fixedly connected to the output end of the sealing motor 28. A drive rod 20 is rotatably connected to the crank disk 22. A connecting plate 27 is symmetrically and rotatably connected between multiple window leaf plates 2. The connecting plate 27 is rotatably connected to the drive rod 20.

[0050] An installation frame 23 is fixedly connected to the inner side of the exhaust vent 16. Window blades 2 are equidistantly distributed on the inner side of the installation frame 23, and multiple window blades 2 are rotatably connected to the installation frame 23. Sealing boxes 24 are fixedly connected to the top and bottom of the inner side of the installation frame 23. Multiple return springs 26 are fixedly installed on the inner side of the sealing box 24 at equal intervals. A sealing plate 25 fixedly connected to the return springs 26 is slidably arranged on the inner side of the sealing box 24. The sealing plate 25 is in contact with the adjacent window blades 2.

[0051] Furthermore, during operation, the cooling fan 13 always rotates, drawing in outside air from the cabinet 1 and exchanging energy with the hot air inside the cabinet 1, finally expelling it from the bottom of the cabinet 1. The cabinet 1 should be equipped with temperature and humidity sensors to monitor the external weather conditions. In foggy weather, the angles of multiple window slats 2 should be adjusted according to the actual weather conditions. If the fog is heavy, the tilt angle of the window slats 2 should be larger, and if the fog is light, the tilt angle of the window slats 2 should be smaller.

[0052] Furthermore, during the adjustment process, the sealed motor 28 starts, driving the crankshaft 22 at its output end to rotate. The rotation of the crankshaft 22 drives the connecting plate 27 to move through the drive rod 20. Since multiple window leaf plates 2 are symmetrically rotated and connected to the inner side of the mounting frame 23, and are linked through the connecting plate 27, the action of the drive rod 20 will drive all window leaf plates 2 to rotate synchronously, thereby synchronously adjusting the angle of all window leaf plates 2. At this time, external air can enter the cabinet 1 through multiple waterproof meshes 21 fixedly connected between adjacent window leaf plates 2. The waterproof meshes 21 can effectively intercept fog and water droplets in the air, achieving anti-fog ventilation.

[0053] Furthermore, such as Figure 15 As shown, when the tilt angle of the window slat 2 changes, the waterproof mesh 21 will also change synchronously, specifically from a vertical state to a tilted state. The waterproof mesh 21 always remains perpendicular to the window slat 2. Water droplets attached to the waterproof mesh 21 drip onto the window slat 2 under the action of gravity and are eventually discharged outside the cabinet 1. In addition, during the change of the angle of the waterproof mesh 21, the horizontal distance between two adjacent waterproof meshes 21 changes. The larger the tilt angle, the more obvious the effect of gravity and the better the anti-fog effect. Since there is always a gap between the waterproof meshes 21, the ventilation effect will not be affected.

[0054] Furthermore, taking the weather in northern China as an example, foggy weather usually occurs in autumn and winter. At this time, the outside temperature is low, and the probability of cabinet 1 malfunctioning due to high temperature is low. In high temperature and low humidity environment, window leaf plate 2 should be in a horizontal state to accelerate air circulation. In rainy weather and high temperature and high humidity environment, the tilt angle of window leaf plate 2 should be adjusted appropriately to ensure ventilation and improve waterproof effect.

[0055] Furthermore, as the tilt angle of the window leaf plate 2 changes, the sealing plate 25, under the elastic force of the return spring 26, adheres tightly to the window leaf plate 2, preventing external dust and moisture from entering the cabinet 1 from the bottom and top of the inner side of the mounting frame 23.

[0056] Example 4

[0057] like Figures 6-8As shown, based on the above embodiments, in this embodiment, the monitoring component also includes a monitoring motor 4 fixedly installed on the top of the cabinet 1. A first threaded rod 43 and a second threaded rod 44 are rotatably connected to the inner side of the cabinet 1. The second threaded rod 44 is symmetrically provided with vertical limiting grooves 440. Monitoring sprockets 41 are fixedly installed at the ends of the first threaded rod 43 and the second threaded rod 44 extending to the outer side of the top of the cabinet 1. A monitoring chain 42 is sleeved and connected between the two monitoring sprockets 41. The output end of the monitoring motor 4 is connected to the second threaded rod 44 for transmission. U-shaped guide plates 40 fixedly connected to the cabinet 1 are provided on the outer sides of the first threaded rod 43 and the second threaded rod 44. The first threaded rod 43 and the second threaded rod 44 are threadedly connected to the movable slide rail 45. The movable slide rail 45 is slidably arranged on the inner side of the two U-shaped guide plates 40.

[0058] The two ends of the movable slide rail 45 are respectively fixedly connected to a second bearing seat 410 and a first bearing seat 49. The second bearing seat 410 is rotatably connected to a first active bevel gear 46 that engages and slides with a vertical limiting slide groove 440. The first active bevel gear 46 is meshed with a first driven bevel gear 47. The second bearing seat 410 and the first bearing seat 49 are rotatably connected to a transverse threaded rod 48. The transverse threaded rod 48 is symmetrically provided with horizontal limiting slide grooves 480. The transverse threaded rod 48 is fixedly connected to the first driven bevel gear 47. The horizontal movable bearing bracket 411 is threadedly connected to the transverse threaded rod 48.

[0059] The inner side of the horizontal moving bearing bracket 411 is rotatably connected to a second active bevel gear 414 that engages with a horizontal limiting slide groove 480. A second driven bevel gear 417 meshes with the second active bevel gear 414. The inner side of the horizontal moving bearing bracket 411 is rotatably connected to a monitoring transmission shaft 418 that is fixedly connected to the second driven bevel gear 417. A monitoring bevel gear 416 is fixedly connected to the outer side of the monitoring transmission shaft 418. Driven half-angle gears 415 are symmetrically arranged on the outer side of the monitoring bevel gear 416. Only one driven half-angle gear 415 meshes with the monitoring bevel gear 416 at a time. The two driven half-angle gears 415 are fixedly connected to a connecting rod 413. Two temperature monitoring heads 412 are fixedly connected to the two ends of the connecting rod 413 respectively.

[0060] Furthermore, regardless of the environment, the monitoring component is always in a periodic working state. During one cycle of operation, the monitoring motor 4 drives the second threaded rod 44 to rotate. Through the transmission of the two monitoring sprockets 41 and the monitoring chain 42, the first threaded rod 43 rotates synchronously. Under the limiting action of the U-shaped guide plate 40, the movable slide rail 45, which is threadedly connected to the first threaded rod 43 and the second threaded rod 44, moves vertically to realize the vertical scanning of the temperature monitoring component. While the movable slide rail 45 moves vertically, the first active bevel gear 46 engages and slides with the vertical limiting slide groove 440 and rotates accordingly, driving the first driven bevel gear 47, which meshes with it, to rotate. This, in turn, drives the transverse threaded rod 48, which is fixedly connected to the first driven bevel gear 47, to rotate. Under the constraint of the movable slide rail 45, the horizontal movable bearing bracket 411, which is threadedly connected to the transverse threaded rod 48, moves horizontally to realize the horizontal scanning.

[0061] Furthermore, the first threaded rod 43 and the second threaded rod 44 have the same pitch. By setting the pitch of the second threaded rod 44 and the transverse threaded rod 48, it is ensured that when the moving slide rail 45 moves from the bottom to the top of the cabinet 1, the horizontal moving bearing bracket 411 moves from one end of the second bearing seat 410 to one end of the first bearing seat 49. The horizontal movement of the horizontal moving bearing bracket 411 will drive its second active bevel gear 414 to slide and rotate in the horizontal limiting slide groove 480. The second active bevel gear 414 drives the second driven bevel gear 417 meshing with it to rotate, thereby driving the monitoring transmission shaft 418 and the monitoring bevel gear 416 fixed on it to rotate. The monitoring bevel gear 416 periodically interacts with the two driven bevel gears. The driven half-angle gears 415 mesh alternately. Since only one driven half-angle gear 415 meshes with the monitoring bevel gear 416 at a time, when the monitoring bevel gear 416 rotates, it drives the currently meshed driven half-angle gear 415 to rotate 180 degrees. This drives the two temperature monitoring heads 412 to turn towards the electrical component mounting plate 14 for temperature measurement via the connecting rod 413. When the monitoring bevel gear 416 meshes with another driven half-angle gear 415, the two temperature monitoring heads 412 reverse their direction to perform monitoring. This cycle repeats, allowing the two temperature monitoring heads 412 to take turns performing a comprehensive temperature scan monitoring of the electrical components on the electrical component mounting plate 14 with a phase difference of 180°.

[0062] Furthermore, when the temperature of a certain part of the electrical component on the electrical component mounting plate 14 is detected to be too high, the controller installed in the cabinet 1 drives the cooling fan 13 to rotate faster, drives the sealing motor 28 to keep the window leaf plate 2 in a horizontal state, increases the air flow rate, and monitors the motor 4 to stop rotating. The temperature monitoring head 412 continuously monitors this abnormal temperature area. Once the temperature exceeds the warning value, the controller immediately cuts off the corresponding circuit to prevent fire.

[0063] Example 5

[0064] like Figures 9-14 As shown, based on the above embodiments, in this embodiment, the dustproof component also includes electric guide rails 3 fixedly installed on the bottom and top of the inner side of the cabinet 1. Multiple limiting posts 30 are provided on the inner side of the two electric guide rails 3. The limiting posts 30 are fixedly connected to the cabinet 1. A guide rail motor 360 is installed on the electric guide rail 3. An installation strip 38 is fixedly connected between the two guide rail motors 360. A cloth tube 34 is fixedly installed on the inner side of the cabinet 1. An adhesive plate 312 is fixedly connected to the outer side of the cloth tube 34. A take-up and release shaft 313 is rotatably connected to the inner side of the cloth tube 34. A dustproof cloth 35 is wrapped around the outer side of the take-up and release shaft 313, and one end is fixedly connected to it. The other end of the dustproof cloth 35 is fixedly connected to the installation strip 38.

[0065] A dustproof motor 31, which is connected to the retracting shaft 313, is fixedly installed on the top of the cabinet 1. A dustproof drive gear 32 is also fixedly connected to the output end of the dustproof motor 31. A dust cylinder 315, which is fixedly connected to the cabinet 1, is provided on the inner side of the dustproof cloth 35. A cleaning shaft 314 is rotatably connected to the inner side of the dust cylinder 315. The cleaning shaft 314 is fixedly connected to the cleaning roller 311. The cleaning shaft 314 is in contact with the inner side of the dustproof cloth 35. The dust cylinder 315 is fixedly connected to the scraper 316. A dustproof driven gear 33 is fixedly connected to one end of the cleaning shaft 314 that extends to the outer side of the top of the cabinet 1. The dustproof drive gear 32 and the dustproof driven gear 33 mesh with each other.

[0066] The outer side of the dustproof cloth 35 is provided with a cleaning rod 310 that is rotatably connected to the cabinet 1. The outer side of the cleaning rod 310 is symmetrically fixed with a push plate 37. The bottom and top of the inner side of the cabinet 1 are rotatably connected with an electric telescopic rod 36. The telescopic end of the electric telescopic rod 36 is rotatably connected to the push plate 37. The cleaning brush 39 is in contact with the outer side of the dustproof cloth 35.

[0067] Furthermore, during use, the dustproof cloth 35 should be kept unfolded and wrapped around the outside of the two electrical component mounting plates 14. When the dustproof cloth 35 is in use, the dustproof motor 31 starts and drives the take-up and release shaft 313 to rotate inside the cloth tube 34 through the transmission connection, thereby releasing the dustproof cloth 35 wrapped on it. At this time, the guide rail motor 360 drives the mounting strip 38 to move on the electric guide rail 3. The mounting strip 38 drives the free end of the dustproof cloth 35 to unfold smoothly, so that the dustproof cloth 35 covers the area that needs protection. Since the dustproof cloth 35 is made of flexible material, the dustproof cloth 35 is limited by the circumferentially set limit post 30 to ensure that it is enclosed in an arc shape. When the guide rail motor 360 moves and contacts the bonding plate 312, the bonding plate 312 is provided with a groove adapted to the guide rail motor 360 to prevent dust from entering from here.

[0068] Furthermore, during the unwinding process of the dustproof cloth 35, the dustproof cloth 35 located inside the cloth drum 34 is in contact with the outside. Dust on the outer surface of the dustproof cloth 35 will adhere to the inside, causing contamination. Therefore, during the rotation of the dustproof motor 31, the dustproof drive gear 32 at the output end drives the dustproof driven gear 33 meshing with it to rotate. In turn, the dustproof driven gear 33 drives the cleaning shaft 314 and the cleaning roller 311 fixedly connected thereto to rotate synchronously. During this process, the inner side of the dustproof cloth 35 remains in contact with the continuously rotating cleaning shaft 314. At the same time, the continuously rotating cleaning roller 311 uses the scraper 316 provided on its outer wall to scrape the inner side of the dustproof cloth 35. The removed dust and impurities fall into the dust drum 315 for temporary storage under the guidance of the scraper 316.

[0069] Furthermore, after a period of use, the cooling fan 13 draws in outside air, passes through the exhaust vent 16, through the dustproof cloth 35, and finally exits from the bottom of the cabinet 1. Dust will continue to accumulate on the outer surface of the dustproof cloth 35. When cleaning the dustproof cloth 35, it should be done in a dry environment. The cooling fan 13 needs to blow air in reverse to blow the dust out of the waterproof mesh 21 of the exhaust vent 16. The aperture of the waterproof mesh 21 is large enough to blow away large particles on the waterproof mesh 21. At this time, the dustproof motor 31 reverses, and the guide rail motor 360 moves in the opposite direction to rewind the dustproof cloth 35. The telescopic end of the electric telescopic rod 36 moves to push the push plate 37 that is rotatably connected to it, so that the cleaning rod 310 swings around its rotatable connection point with the cabinet 1, thereby driving the cleaning brush 39 fixed on it to contact the outer side of the dustproof cloth 35 for brushing, ensuring that the dustproof cloth 35 remains clean during the retraction process.
