Description

Technical Field

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

[0002] Outdoor distribution cabinets are complete sets of electrical equipment specifically designed for outdoor, open-air, and semi-open-air environments to perform functions such as power distribution, control, protection, and metering. Compared with indoor distribution cabinets, the core differences lie in the protection level, structural materials, and environmental adaptability. They are widely used in outdoor power distribution scenarios such as residential areas, factories, municipal roads, photovoltaic power stations, and charging piles. Because the electrical components inside the distribution cabinet operate at high temperatures, these temperatures can directly lead to accelerated component aging, protection malfunctions, and insulation failure, and in severe cases, short circuits and fires. Therefore, protective mechanisms are required for the distribution cabinets. These protective structures mainly include inlet and outlet air filters installed inside the cabinet to intercept dust from outside. Additionally, fans or other equipment are installed inside the cabinet to achieve cooling by exchanging airflow between the outside and inside. However, outdoor distribution cabinets... Ventilation can also bring external dust and other substances into the distribution cabinet. Dust can adhere to electrical components, and its conductivity and hygroscopicity can cause insulation failures in these components. Therefore, filters are installed on the air inlets and outlets of outdoor distribution cabinets to intercept dust. However, as airflow passes through the filter at the air inlet and enters the distribution cabinet, the filter can become clogged over time, resulting in poor ventilation. Existing technology uses an impact mechanism, activated periodically by a control system, to impact the filter, causing the dust on the filter to fall and ensuring that the filter is reventilated. However, outdoor environments are complex and changeable. The filter is often impacted at fixed intervals even when the blockage is not severe. Frequent impacts reduce the lifespan of the filter. If the impact interval is set too long, it cannot be guaranteed that the filter will receive timely impacts when it is clogged, thus ensuring that the filter remains unobstructed. Summary of the Invention

[0003] To address the technical problems mentioned in the background section, the present invention provides an outdoor power distribution cabinet with a protective structure, the technical solution of which is as follows:

[0004] The system includes a cabinet with an upper and lower door. A fixed frame is attached inside the cabinet, and several electrical components are fixedly connected to the frame. A protective structure is installed on the cabinet. Air inlets and exhaust outlets are located on both sides of the cabinet. The protective structure includes an air inlet assembly inside the cabinet, fixed to the air inlet, and an impact assembly outside the cabinet, fixed to the air inlet assembly. An exhaust assembly is inside the cabinet, fixed to the exhaust outlet. A flexible assembly is also inside the cabinet, with one end connected to the air inlet assembly and the other end connected to the exhaust assembly. A relay is fixedly connected to the frame, and the relay is electrically connected to both the air inlet and exhaust assemblies.

[0005] Furthermore, the air intake assembly includes a square channel installed inside the cabinet. The square channel is fixed to the air inlet. Slide grooves are provided on the inner walls of the four directions of the square channel. A slider is slidably installed in the slide groove. An air intake filter is snapped into the square channel. The slider is fixedly connected to the filter frame of the air intake filter. An air intake filter fixing block is fixedly embedded in the center of the air intake filter. The center of the air intake filter fixing block is fixedly connected to the elastic component. The impact component is fixedly connected to the outer wall of the square channel.

[0006] Furthermore, the impact assembly includes a frame, a connecting plate fixedly connected to the frame, the connecting plate being fixedly connected to the outer wall of the square channel, a frame fixing block provided inside the frame, a plurality of fixing plates provided on the frame fixing block, the fixing plates being fixedly connected to the inner wall of the frame, a limit hole provided on the fixing plate, an impact member fixedly connected to the fixing plate, one end of the impact member being movably connected in the limit hole, a switch base a fixedly connected to the frame fixing block, a button a provided on the switch base a, and the switch base a being electrically connected to the relay.

[0007] Furthermore, the cabinet is equipped with a sealed conduit, through which the wire of switch seat a passes to the relay for electrical connection.

[0008] Furthermore, the impact component includes a U-shaped frame fixed to the fixed plate, with a limiting rod movably connected through the center of the U-shaped frame. One end of the limiting rod is movably connected to a limiting hole, and the other end is fixedly connected to an impact ball. A circular plate is fixedly connected to the limiting rod. A spring a is provided inside the U-shaped frame, and spring a is sleeved on the limiting rod. One end of spring a is fixedly connected to the circular plate, and the other end is fixedly connected to the U-shaped frame.

[0009] Furthermore, the exhaust assembly includes an exhaust filter screen installed at the exhaust vent. An exhaust filter screen fixing block is fixedly embedded in the center of the exhaust filter screen. A switch base b is fixedly connected to the exhaust filter screen fixing block. A button b is provided on the switch base b. The switch base b is electrically connected to a relay. An exhaust hood located inside the cabinet is fixedly connected to the filter screen frame of the exhaust filter screen. An exhaust pipe is fixedly connected to one end of the exhaust hood. A blower is connected to one end of the exhaust pipe. A straight groove is opened at the top of the exhaust pipe. An arc-shaped sealing plate is movably installed on the inner wall of the exhaust pipe at the bottom of the straight groove. A sealing plug is movably connected inside the exhaust pipe. The sealing plug is fixedly connected to the arc-shaped sealing plate. A straight rod is fixedly connected to the end of the sealing plug. The upper part of the arc-shaped sealing plate is connected to an elastic component.

[0010] Furthermore, the elastic component includes a cylindrical body with closed structures at both ends, which is set inside the cabinet. A limit plate is movably installed inside the cylindrical body. A spring b is installed between the limit plate and the cylindrical body. One end of the spring b is connected to the limit plate and the other end is connected to the cylindrical body. It also includes an L-shaped push rod, which movably passes through the front and rear ends of the cylindrical body and the inside of the spring b and is fixedly connected to the center of the limit plate. One end of the L-shaped push rod is connected to the center of the air inlet filter fixing block and the other end is fixedly connected to the upper part of the arc-shaped sealing plate.

[0011] Furthermore, an arc-shaped fixing plate is fixedly connected to the cylinder body, with one end of the arc-shaped fixing plate fixed to the inner wall of the cabinet.

[0012] Furthermore, both the intake and exhaust filters are made of metal.

[0013] Furthermore, a support plate is fixedly connected to the bottom of the blower, and the support plate is fixedly connected to the inner wall of the cabinet.

[0014] This invention has the following advantages: When the impact component is activated, the exhaust component draws external airflow into the cabinet through the intake component, and then discharges it through the exhaust component. External dust is intercepted by the intake component. As the dust accumulates on the intake component, the ventilation volume gradually decreases, and the external atmospheric pressure gradually exceeds the atmospheric pressure inside the cabinet. The intake component gradually moves towards the inside of the cabinet, causing the elastic component to move. The elastic component gradually moves and causes part of the exhaust component's structure to move until the inside of the exhaust component is touched, causing the intake component to close and the exhaust component to lose power. The elastic component quickly rebounds and causes the intake component to move back quickly. The intake component hits the impact component, causing the dust on the intake component to fall off. At the same time, the intake component presses the impact component to reopen the impact component, thus reopening the exhaust component. This invention enables the intake component to automatically impact and shake off the dust when it reaches its maximum blockage level, reducing the impact frequency and shortening the lifespan of the intake component. It also avoids the situation where the intake component fails to shake off the dust in time when it reaches its maximum blockage level, affecting the heat dissipation inside the distribution cabinet and causing damage to the electronic components inside the distribution cabinet.

[0027] 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.

[0028] Please refer to Figure 1-11 This invention provides an outdoor power distribution cabinet with a protective structure, including a cabinet body 1. The cabinet body 1 is connected to an upper cabinet door 2 and a lower cabinet door 3. The cabinet body is sealed by closing the upper cabinet door 2 and the lower cabinet door 3. The upper cabinet door 2 and the lower cabinet door 3 facilitate the maintenance of electrical components 5 inside the power distribution cabinet 1. A fixing frame 4 is fixedly connected inside the cabinet body 2. Several electrical components 5 are fixedly connected to the fixing frame 4. The electrical components 5 are the core mechanism for the operation of the power distribution cabinet. The electrical components 5 are fixed inside the cabinet body 1 by installing them on the fixing frame 4.

[0029] A protective structure is installed on the cabinet 1. Air inlets 6 and exhaust outlets 7 are respectively located on both sides of the cabinet 1. The protective structure includes an air inlet assembly installed inside the cabinet 1, fixed to the air inlet 6. External airflow enters the cabinet 1 through the air inlet assembly, which intercepts external dust. It also includes an impact assembly installed on the outside of the cabinet 1, which impacts the air inlet assembly, causing dust to be shaken off. Simultaneously, the impact assembly controls the power supply to the exhaust assembly. The impact assembly is fixed to the air inlet assembly. An exhaust assembly is installed inside the cabinet 1 and is fixed to the exhaust port 7. The exhaust assembly allows external airflow to enter the cabinet 1 and then exit from the cabinet 1, thereby achieving airflow exchange within the cabinet 1 and cooling the cabinet 1. An elastic assembly is also installed inside the cabinet 1. One end of the elastic assembly is connected to the air inlet assembly and the other end is connected to the exhaust assembly. The elastic assembly has an elastic function and can drive the movement of some structures of the air inlet assembly and the exhaust assembly. A relay 8 is fixedly connected to the mounting bracket 4, and the relay 8 is electrically connected to the air inlet assembly and the exhaust assembly respectively.

[0030] The air intake assembly includes a square channel 9 installed inside the cabinet 1. The square channel 9 is fixed to the air inlet 6. Slide grooves 10 are provided on the inner walls of the four directions of the square channel 9. A slider 11 is slidably installed in the slide groove 10. An air intake filter 12 is snapped into the square channel 9, forming a seal between the air intake filter 12 and the square channel 9. The slider 11 is fixedly connected to the filter frame of the air intake filter 12. The movement of the air intake filter 12 within the square channel 9 is achieved by the slider 11 sliding in the slide groove 10. An air intake filter fixing block 13 is fixedly embedded in the center of the air intake filter 12. The center of the air intake filter fixing block 13 is fixedly connected to an elastic component. The movement of the air intake filter fixing block 13, driven by the elastic component, drives the movement of the air intake filter 12. The impact component is fixedly connected to the outer wall of the square channel 9.

[0031] The impact assembly includes a frame 14, on which a connecting plate 15 is fixedly connected. The connecting plate 15 is fixedly connected to the outer wall of the square channel 9, and the frame 14 is fixed to the square channel 9 through the connecting plate 15. A frame fixing block 16 is provided on the inner side of the frame 14, and several fixing plates 17 are provided on the frame fixing block 16. The fixing plates 17 are fixedly connected to the inner wall of the frame 14. Limiting holes 18 are provided on the fixing plates 17. An impact member is fixedly connected to the fixing plate 17, and one end of the impact member is movably connected in the limiting hole 18. A switch base a19 is fixedly connected to the frame fixing block 16, and a button a20 is provided on the switch base a19. The switch base a19 realizes the opening or closing of the contacts of the button a20. The switch base a19 is electrically connected to a relay 8, and the relay 8 controls the power supply or de-energization of the switch base a19.

[0032] A sealed conduit 21 is provided on the cabinet 1. The wires of the switch base a19 are sealed through the sealed conduit 21 and electrically connected to the relay 8. Since the switch base a19 is located outside the cabinet 1, when it is connected to the relay 8 located inside the cabinet 1, in order to ensure the airtightness of the cabinet 1, the wires on the switch base a19 are sealed through the sealed conduit 21 and connected to the relay 8. The relay 8 is connected to the electrical components 5 inside the cabinet 1 to achieve power supply. This is the prior art.

[0033] The impact component includes a U-shaped frame 22 fixed on a fixed plate 17. A limiting rod 23 is movably connected through the center of the U-shaped frame 22. One end of the limiting rod 23 is movably connected to a limiting hole 18, and the other end is fixedly connected to an impact ball 24. A circular plate 25 is fixedly connected to the limiting rod 23. A spring a26 is provided inside the U-shaped frame 22. The spring a26 is sleeved on the limiting rod 23. One end of the spring a26 is fixedly connected to the circular plate 25, and the other end is fixedly connected to the U-shaped frame 22. When the impact ball 24 is impacted and squeezed, the impact ball 24 drives the limiting rod 23 and the circular plate 25 to move closer to the fixed plate 17. The spring a26 is stretched, and the limiting rod 23 moves within the limiting hole 18.

[0034] The exhaust assembly includes an exhaust filter 27 installed at the exhaust port 7. An exhaust filter fixing block 28 is fixedly embedded in the center of the exhaust filter 27. A switch base b29 is fixedly connected to the exhaust filter fixing block 28. A button b30 is provided on the switch base b29. The switch base b29 is electrically connected to the relay 8. The switch base b28 is also electrically connected to the relay 8 via wires. An exhaust hood 31 located inside the cabinet 1 is fixedly connected to the filter frame of the exhaust filter 27. An exhaust pipe 32 is fixedly connected to one end of the exhaust hood 31. A blower 33 is connected to one end of the exhaust pipe 32. The blower 33 is electrically connected to the relay 8. The airflow in the cabinet 1 enters the blower 33 through the air inlet of the blower 33. The airflow in the blower 33 enters the exhaust pipe 32 and the exhaust hood 31, and then is discharged through the exhaust filter 27. The exhaust hood 31 gathers the airflow and concentrates it to pass through the exhaust filter 27.

[0035] The upper part of the exhaust pipe 32 has a straight groove 34. An arc-shaped sealing plate 35 is movably installed on the inner wall of the exhaust pipe 32 at the bottom of the straight groove 34. The arc-shaped sealing plate 35 can be attached to the inner wall of the exhaust pipe 32 and move horizontally back and forth to seal the straight groove 34, preventing external airflow from entering the exhaust pipe 32 through the straight groove 34. A sealing plug 36 is movably connected inside the exhaust pipe 32. The sealing plug 36 is fixedly connected to the arc-shaped sealing plate 35. A straight rod 43 is fixedly connected to the end of the sealing plug 36. The upper part of the arc-shaped sealing plate 35 is connected to an elastic component. The elastic component drives the arc-shaped sealing plate 35 to move, and the sealing plug 36 drives the straight rod 43 of the arc-shaped sealing plate 35 to move.

[0036] The elastic component includes a cylindrical body 37 with closed ends, located inside the cabinet 1. A limiting plate 38 is movably installed inside the cylindrical body 37. A spring b39 is installed between the limiting plate 38 and the cylindrical body 27. One end of the spring b39 is connected to the limiting plate 38, and the other end is connected to the cylindrical body 37. The component also includes an L-shaped push rod 40, which movably passes through the front and rear ends of the cylindrical body 37 and the inside of the spring b39, and is fixedly connected to the center of the limiting plate 38. One end of the L-shaped push rod 40 is connected to the center of the air inlet filter fixing block 13, and the other end is connected to the arc-shaped sealing plate 35. The upper part is fixedly connected. The L-shaped push rod 40 passes through the straight groove 34 and is connected to the upper part of the arc-shaped sealing plate 35. The L-shaped push rod 40 can move back and forth in the straight groove 34. The straight groove 34 plays a limiting role for the L-shaped push rod 40. The width of the straight groove 34 is equal to the diameter of the L-shaped push rod 40. The blower 33 drives the airflow into the exhaust pipe 32. The airflow in the exhaust pipe 32 pushes the sealing plug 36 to move. The sealing plug 36 drives the arc-shaped sealing plate 35, the L-shaped push rod 40 and the straight rod 43 to move. The L-shaped push rod 40 drives the limiting plate 38 to move, and the spring b39 is compressed.

[0037] It should be noted that the elasticity of spring b39 is greater than that of spring a26.

[0038] It should be noted that button A20 is a normally open switch, and button B30 is an emergency stop switch. The connection of switch bases A19 and B29 to relay 8, and the presence of button A20 on switch base A19 and button B30 on switch base B29, are existing technologies commonly used in current industrial equipment. The principle is that when button A20 is pressed, blower 33 is energized. When button B30 is pressed, the contacts of button A20 open, de-energizing blower 33. When button A20 is pressed again, blower 33 is energized, and the contacts of button B30 open. Therefore, button A20 only has an "on" function, and its contacts open based on the pressing of button B30. Button B30 only has an "off" function, and its contacts open based on the pressing of button A20.

[0039] An arc-shaped fixing plate 41 is fixedly connected to the cylindrical body 37. One end of the arc-shaped fixing plate 41 is fixed to the inner wall of the cabinet 1, and the cylindrical body 37 is fixed to the cabinet 1 through the arc-shaped fixing plate 41.

[0040] Both the intake filter 12 and the exhaust filter 27 are made of metal, which is relatively hard and not easily deformed when impacted.

[0041] A support plate 42 is fixedly connected to the bottom of the blower 33. The support plate 42 is fixedly connected to the inner wall of the cabinet 1. The blower 33 is fixed to the cabinet 1 through the support plate 42.

[0042] The working principle of this invention is as follows: Initially, the air inlet filter fixing block 13 presses button a20 and rests against button a20, energizing and starting the blower 33. External airflow enters the cabinet 1 through the air inlet filter 12. The airflow inside the cabinet 1 enters the blower 33 through the air inlet of the blower 33. The airflow inside the blower 33 enters the exhaust pipe 32. Under the pressure of the air, the sealing plug 36 inside the exhaust pipe 32 moves towards the exhaust filter 27. The sealing plug 36 disengages from the exhaust pipe 32, allowing the airflow inside the exhaust pipe 32 to enter the exhaust hood 32. The airflow inside the exhaust hood 31 is discharged outside the cabinet 1 through the exhaust filter 27, achieving airflow exchange within the cabinet 1 and cooling the cabinet 1. During this process, due to the movement of the sealing plug 36... The sealing plug 36 moves the arc-shaped sealing plate 35, which in turn moves the L-shaped push rod 40. The L-shaped push rod 40 moves through the cylinder 37 and moves the limiting plate 38, compressing the spring b39. The left end of the L-shaped push rod 40 moves the air inlet filter fixing block 13, which in turn moves the air inlet filter 12 within the direction channel 9. The air inlet filter 12 moves the slider 11 within the slide groove 10. The sealing plug 36 also moves the straight rod 43, which stops when it reaches a certain distance. At this point, the straight rod 43 is still a certain distance from the button b30. As more and more dust is intercepted on the air inlet filter 12, more and more dust adheres to it, and the air inlet filter 12 gradually becomes clogged. As the airflow inside cabinet 1 decreases, while blower 33 continues to operate, the air pressure inside cabinet 1 gradually decreases compared to the external pressure. Under the guidance of external pressure, the inlet filter 12 gradually moves towards the inside of the square channel 9, driving the L-shaped push rod 40 to continue moving towards the exhaust filter 27 (the flow rate of blower 33 remains constant). The L-shaped push rod 40 drives the arc-shaped sealing plate 35, sealing plug 36, and straight rod 43 to gradually move towards the exhaust filter 27 until the straight rod 43 contacts and presses button b30. At this point, the inlet filter 12 is blocked to its maximum extent. With the pressing of button b30, the contact of button a20 disconnects, and blower 33 is de-energized. Because the L-shaped push rod 40 moves towards the exhaust filter 27, it is equivalent to... The effect is due to two forces: external air pressure and the airflow pressure generated by blower 33. The sum of these two forces is greater than the elastic force of spring b39. Once blower 33 is de-energized and stops, one force is lost, and the elastic force of spring b39 becomes greater than the atmospheric pressure outside cabinet 1. Spring b39 quickly rebounds, causing limit plate 38 and L-shaped push rod 40 to move rapidly towards air inlet filter 12. L-shaped push rod 40 causes air inlet filter fixing block 13 and air inlet filter 12 to move. Air inlet filter 12 first impacts impact ball 24, causing dust on air inlet filter 12 to fall off. During this process, impact ball 24 causes limit rod 23 to move away from square channel 9 within limit hole 18. Limit rod 23 simultaneously causes circular plate 25 to move.The spring a26 is stretched (the elastic force of spring a26 is less than that of spring b39) until the filter screen fixing block 13 contacts and presses button a20, stopping due to the limitation of button a20. In the entire process, the air inlet filter 12 first contacts and is struck by the impact ball 24, and then the air inlet filter fixing block 13 contacts and presses button a20. After button a20 is pressed, the blower 33 is re-energized and runs, while the contacts of button b30 are disconnected, waiting to be pressed again.

[0043] This invention is simple to operate, convenient to use, and suitable for widespread promotion and application. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
