Description

Technical Field

[0001] This invention belongs to the field of electrical engineering, and in particular relates to a double-layer adjustable distribution cabinet. Background Technology

[0002] Distribution cabinets are the final-level equipment in a power distribution system, and are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, etc. They are mainly used in motor control centers and in situations where loads are relatively dispersed and there are few circuits. Their main function is to distribute electrical energy from a circuit of the upstream distribution equipment to nearby loads, and to provide protection, monitoring, and control for these loads. Distribution cabinets play a vital role in power distribution and protection in power systems, and are of great significance for ensuring the normal operation of the power system.

[0003] During operation, distribution cabinets require reliable heat dissipation. However, existing heat dissipation structures are relatively traditional. While they can meet the heat dissipation requirements to some extent, they do not effectively combine heat dissipation, dust removal, and regulation, resulting in limitations and failing to guarantee the reliability and stability of the electrical components within the distribution cabinet. Therefore, there is an urgent need to develop a double-layer adjustable distribution cabinet to overcome the shortcomings in current practical applications. Summary of the Invention

The lower ends of the vertical portions of the L-shaped air blower and the L-shaped return air duct are located on the lower inner side of the main body of the distribution cabinet, and the vertical portions of the L-shaped air blower and the L-shaped return air duct are spaced apart from the inner wall of the main body of the distribution cabinet.

[0011] In a further technical solution, bushings are fixed on both sides of the main body of the power distribution cabinet, and the horizontal parts of the L-shaped air blower and L-shaped return air pipe are correspondingly and rotatably connected to the two bushings.

[0012] In a further technical solution, the fan is fixedly connected to the side wall of the main body of the distribution cabinet via a fan support; the horizontal part of the L-shaped air blowing pipe is rotatably and sealed to the fan, and the outlet of the fan is connected to the L-shaped air blowing pipe; the horizontal part of the L-shaped return air pipe is rotatably and sealed to the inlet air pipe, and the L-shaped return air pipe is connected to the inlet air pipe; the outlet air pipe and the inlet air pipe are also fixedly connected to the main body of the distribution cabinet via pipe supports.

[0013] A further technical solution includes a dust collection cylinder, which has a cylindrical structure and is fixed to the top of the main body of the power distribution cabinet. A motor is also fixed to the top of the dust collection cylinder. A main shaft passes through the dust collection cylinder and is rotatably connected to both the dust collection cylinder and the main body of the power distribution cabinet. An annular dust collection groove is provided at the bottom of the inner cavity of the dust collection cylinder. A filter plate is fixed to the outer side of the top of the annular dust collection groove. The upper end of the filter plate is fixedly connected to the inner wall of the dust collection cylinder. The outer space of the filter plate is the outer annular cavity, and the inner space of the filter plate is the inner cavity. The lower end of the inner cavity is connected to the annular dust collection groove. The air outlet pipe is connected to the outer annular cavity, and the air inlet pipe is connected to the upper part of the inner cavity. At least two support rods are also circumferentially fixed on the main shaft. A scraper that mates with the inner wall of the filter plate is fixed to the outer end of the support rod. A cleaning port is also provided at the top of the dust collection cylinder.

[0014] In a further technical solution, a cooler is also installed on the air inlet pipe, which is an air cooler or a water cooler.

[0015] A further technical solution for this double-layer adjustable distribution cabinet includes an adjustable mounting assembly. This assembly includes a mounting plate, a support base, a lead screw, a guide rail, a second motor, an arc-shaped telescopic rod, and a support plate. A lead screw is located at the center of the rear side of the main body of the distribution cabinet. The two ends of the lead screw are rotatably connected to the top and bottom of the main body of the distribution cabinet, respectively. A second motor, which is driven by the lead screw, is fixed to the top of the main body of the distribution cabinet. A support base is threaded onto the lead screw. A guide rail, which is slidably connected to the support base, is also fixed to the inner wall of the rear side of the main body of the distribution cabinet. A mounting plate is located on the front side of the support base, and a support plate is vertically fixed to the lower side of the mounting plate. The support plate is also connected to the support base via an arc-shaped telescopic rod.

[0017] A further technical solution is provided in which the upper part of the support base is provided with an inclined surface, and a second magnet is embedded and fixed in the inclined surface. A first magnet that can be magnetically connected with the second magnet is embedded and fixed on the upper side of the end of the mounting plate near the support base. When the mounting plate abuts against the inclined surface, the first magnet and the second magnet are magnetically connected, and at this time the end of the mounting plate away from the support base is inclined toward the rear wall of the main body of the power distribution cabinet.

[0018] The present invention provides a double-layer adjustable power distribution cabinet, which has the following beneficial effects:

[0019] By operating the fan, air can be drawn from the outlet duct and delivered to the L-shaped blower duct. The air is then discharged from the blower head, while the return air head draws in air, creating airflow within the main cavity of the distribution cabinet, thereby achieving the goal of ventilation and heat dissipation. After the air is discharged through the L-shaped return air duct and the inlet air duct, it will be filtered for dust by the dust filter assembly and then recirculated to the outlet air duct 8, forming a dust filtration and circulating heat dissipation effect.

[0020] In addition, to enhance the airflow effect and improve heat dissipation efficiency, a motor drive system was introduced. Driven by the motor, the bevel gear 2 starts to rotate, which in turn drives the two bevel gears to rotate synchronously. Through the transmission rod, the L-shaped air blower and L-shaped return air duct rotate in opposite directions. The position of the L-shaped air blower and L-shaped return air duct can be adjusted as needed according to actual requirements, and their reciprocating oscillation can also be realized, thereby forming an airflow disturbance pattern inside the main body of the distribution cabinet, further improving the heat dissipation effect on the internal cavity of the main body of the distribution cabinet.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0031] like Figure 1-4As shown, a double-layer adjustable power distribution cabinet is provided in an embodiment of the present invention, including a power distribution cabinet body 2. The power distribution cabinet body 2 adopts a double-layer structure. The bottom of the power distribution cabinet body 2 is equipped with support legs 1. The front opening of the power distribution cabinet body 2 is equipped with a cabinet door 3. The top of the power distribution cabinet body 2 is supported and fixed with a top cover 6 by a top support rod 7.

[0032] Among them, the double-layer structure of the main body 2 of the power distribution cabinet is preferably filled with insulating material to ensure electrical isolation between the two layers and prevent current from passing directly through the interlayer, thereby ensuring the safe operation of the equipment. The types of insulating materials include, but are not limited to, insulating paperboard, insulating plastic, etc.

[0033] The support legs 1 provide stable support for the main body 2 of the distribution cabinet and give it a certain degree of waterproofing. The cabinet door 3 facilitates the installation and maintenance of electrical components. The top cover 6 provides shade and rain protection for the main body 2 of the distribution cabinet and facilitates the installation of components on the top of the main body 2 of the distribution cabinet, thereby improving reliability.

[0034] Also includes:

[0035] An adjustable ventilation and heat dissipation assembly is provided, comprising an L-shaped air duct 4, an air blower head 5, an air outlet duct 8, a motor 9, an air inlet duct 12, a transmission rod 13, an L-shaped return air duct 14, a return air head 15, a bevel gear 20, a bevel gear 21, a fan 23, and a main shaft 33. A dust filter assembly is installed on the top of the main body 2 of the power distribution cabinet, and a motor 9 is fixed on the top of the dust filter assembly. The output end of the motor 9 is fixed to the main shaft 33, and the lower end of the main shaft 33 extends into the main body 2 of the power distribution cabinet, with a bevel gear 21 fixed at its end.

[0036] L-shaped air ducts 4 and L-shaped return air ducts 14 are rotatably installed on the two side walls of the main body 2 of the power distribution cabinet. Air blowers 5 and return air heads 15 are installed on the side of the L-shaped air ducts 4 and L-shaped return air ducts 14 that are close to each other. A fan 23 is installed on the outside of the main body 2 of the power distribution cabinet at the end of the L-shaped air duct 4. The inlet of the fan 23 is connected to the dust filter assembly through the air outlet duct 8. An air inlet duct 12 is installed on the outside of the main body 2 of the power distribution cabinet at the end of the L-shaped return air duct 14. The other end of the air inlet duct 12 is connected to the dust filter assembly. The dust filter assembly is used to filter the air delivered from the air inlet duct 12 to the air outlet duct 8.

[0037] A transmission rod 13 is fixed to each of the L-shaped air blowing pipe 4 and the L-shaped air return pipe 14. The two transmission rods 13 are respectively fixed with a bevel gear 20 that meshes with the bevel gear 21 at their close ends.

[0038] In this embodiment of the invention, by operating the fan 23, air can be drawn from the outlet duct 8 and delivered to the L-shaped blower duct 4. Then the air is discharged from the blower head 5. At the same time, the return air head 15 draws in the air, forming airflow in the inner cavity of the power distribution cabinet body 2, thereby achieving the goal of ventilation and heat dissipation. After the air is discharged through the L-shaped return air duct 14 and the inlet air duct 12, it will be filtered by the dust filter assembly and then recirculated to the outlet duct 8, forming a dust filtration and circulating heat dissipation effect.

[0039] In addition, to enhance the airflow effect and improve heat dissipation efficiency, a motor-9 drive system is introduced. Driven by the motor-9, the bevel gear 21 starts to rotate, which in turn drives the two bevel gears 20 to rotate synchronously. Through the transmission rod 13, the L-shaped air blower 4 and the L-shaped return air duct 14 are rotated in opposite directions. The positions of the L-shaped air blower 4 and the L-shaped return air duct 14 can be adjusted as needed according to actual requirements, and their reciprocating swing can also be realized, thereby forming an airflow disturbance mode in the main body 2 of the power distribution cabinet, further improving the heat dissipation effect on the inner cavity of the main body 2 of the power distribution cabinet.

[0040] like Figure 1-5 As shown, in a preferred embodiment of the present invention, the horizontal portions of the L-shaped air blower duct 4 and the L-shaped return air duct 14 are arranged coaxially, and the horizontal portions of the L-shaped air blower duct 4 and the L-shaped return air duct 14 are respectively rotatably connected to the upper middle of the two side walls of the main body of the distribution cabinet 2, so that the L-shaped air blower duct 4 and the L-shaped return air duct 14 can swing in a wide range. The lower ends of the vertical portions of the L-shaped air blower duct 4 and the L-shaped return air duct 14 are located on the lower inner side of the main body of the distribution cabinet 2, and the vertical portions of the L-shaped air blower duct 4 and the L-shaped return air duct 14 are spaced apart from the inner wall of the main body of the distribution cabinet 2 to ensure the installation space inside the cavity of the main body of the distribution cabinet 2.

[0041] Furthermore, in order to improve the stability of the L-shaped air blower duct 4 and the L-shaped return air duct 14, bushings 25 are fixed on both sides of the main body 2 of the power distribution cabinet. The horizontal parts of the L-shaped air blower duct 4 and the L-shaped return air duct 14 are respectively sealed and rotatably connected to the two bushings 25.

[0042] The fan 23 is fixedly connected to the side wall of the main body 2 of the power distribution cabinet via the fan support 22, which provides stable support. The horizontal part of the L-shaped air blowing pipe 4 is sealed and rotatably connected to the fan 23, and the outlet of the fan 23 is connected to the L-shaped air blowing pipe 4. The horizontal part of the L-shaped return air pipe 14 is sealed and rotatably connected to the inlet air pipe 12, and the L-shaped return air pipe 14 is connected to the inlet air pipe 12. The outlet air pipe 8 and the inlet air pipe 12 are also fixedly connected to the main body 2 of the power distribution cabinet via the pipe support 27, which provides stable support for the outlet air pipe 8 and the pipe support 27.

[0043] The two transmission rods 13 are coaxially arranged with the horizontal portions of the L-shaped blower pipe 4 and the L-shaped return air pipe 14, which makes the transmission reliable.

[0044] The dust filtration assembly includes a dust collector cylinder 10, which has a cylindrical structure. The dust collector cylinder 10 is fixed to the top of the main body 2 of the power distribution cabinet. A motor 9 is fixed to the top of the dust collector cylinder 10. A main shaft 33 passes through the dust collector cylinder 10 and is rotatably connected to both the dust collector cylinder 10 and the main body 2 of the power distribution cabinet. An annular dust collection groove 32 is provided at the bottom of the inner cavity of the dust collector cylinder 10. A filter plate 29 is fixed to the outer side of the top of the annular dust collection groove 32. The upper end of the filter plate 29 is connected to the dust collector cylinder 10. The filter plate 29 is fixedly connected to the inner wall. The outer space of the filter plate 29 is an outer annular cavity 34, and the inner space of the filter plate 29 is an inner cavity 35. The lower end of the inner cavity 35 is connected to the annular dust collection groove 32. The air outlet pipe 8 is connected to the outer annular cavity 34, and the air inlet pipe 12 is connected to the upper part of the inner cavity 35. At least two support rods 31 are also circumferentially fixed on the main shaft 33. The outer end of the support rod 31 is fixed with a scraper 30 that cooperates with the inner wall of the filter plate 29. The top of the dust collector 10 is also provided with a cleaning port 28. The filter plate 29 can filter the dust from the air delivered from the air inlet pipe 12 to the air outlet pipe 8. When the motor 9 drives the main shaft 33 to rotate, the main shaft 33 drives the scraper 30 to rotate, which can scrape off the dust on the inner wall of the filter plate 29 and let it fall into the annular dust collection groove 32. The annular dust collection groove 32 can be cleaned by opening the cleaning port 28 periodically.

[0045] Preferably, in order to improve the ventilation and heat dissipation effect, a cooler 11 is also installed on the air inlet duct 12. The cooler 11 can absorb the heat in the air inside the air inlet duct 12. It can be an air cooler, a water cooler, etc., without limitation or elaboration.

[0046] like Figure 1 , 3 As shown in Figures 4, 6, and 7, in a preferred embodiment of the present invention, the double-layer adjustable distribution cabinet further includes an adjustable mounting assembly. The adjustable mounting assembly includes a mounting plate 16, a support base 17, a lead screw 18, a guide rail 19, a second motor 24, an arc-shaped telescopic rod 39, and a support plate 40. A lead screw 18 is provided in the middle of the rear side of the distribution cabinet body 2. The two ends of the lead screw 18 are rotatably connected to the top and bottom of the distribution cabinet body 2, respectively. A second motor 24, which is drivenly connected to the lead screw 18, is fixed to the top of the distribution cabinet body 2. The support base 17 is threadedly connected to the lead screw 18. A guide rail 19, which is slidably connected to the support base 17, is also fixed to the inner wall of the rear side of the distribution cabinet body 2. A mounting plate 16 is provided in front of the support base 17. A support plate 40 is vertically fixed to the lower side of the mounting plate 16. The support plate 40 is also connected to the support base 17 through the arc-shaped telescopic rod 39.

[0047] Preferably, the arc-shaped telescopic rod 39 adopts an arc-shaped structure, with the center of the arc-shaped telescopic rod 39 located on the abutment line between the upper part of the mounting plate 16 and the support seat 17. The cylinder of the arc-shaped telescopic rod 39 is embedded and fixed in the support seat 17, and the output end of the arc-shaped telescopic rod 39 is fixedly connected to the support plate 40, ensuring that when the mounting plate 16 is horizontal, the support plate 40 abuts against the surface of the support seat 17 and remains stable.

[0048] Preferably, the upper part of the support base 17 is provided with an inclined surface 38, and a second magnet 37 is embedded and fixed in the inclined surface 38. A first magnet 36 that can be magnetically connected to the second magnet 37 is embedded and fixed on the upper side of the mounting plate 16 near the support base 17. When the mounting plate 16 abuts against the inclined surface 38, the first magnet 36 and the second magnet 37 are magnetically connected. At this time, the end of the mounting plate 16 away from the support base 17 is inclined towards the rear side wall of the power distribution cabinet body 2, and the gravity of the mounting plate 16 is used to ensure that the mounting plate 16 is in a stable receiving state.

[0049] In practical applications, the arc-shaped telescopic rod 39 can be a regular telescopic rod. By moving the mounting plate 16, magnet 36 and magnet 37 separate. Then, the weight of the mounting plate 16 allows the support plate 40 to abut against the surface of the support base 17. The fixed connection structure of the arc-shaped telescopic rod 39 ensures that the mounting plate 16 is in a horizontal and stable state, allowing it to meet the installation requirements of electrical components. When the mounting plate 16 needs to be folded, the screw 18 can be rotated by the motor 24 to adjust the position of the support base 17. Then, the mounting plate 16 is flipped upwards and abuts against the inclined surface 38. The magnetic attraction of magnets 36 and 37, along with the weight of the mounting plate 16 itself, ensures the folding stability of the mounting plate 16.

[0050] This invention provides a double-layer adjustable power distribution cabinet. The fan 23 draws air from the outlet duct 8 and delivers it through the L-shaped blower duct 4 to the blower head 5 for discharge. Simultaneously, the return air head 15 draws in air, allowing air circulation within the cabinet body 2 to achieve ventilation and heat dissipation. To ensure air cleanliness, the air passes through the L-shaped return air duct 14 and the inlet duct 12 during circulation, and is filtered by a dust filter assembly. Specifically, the filter plate 29 is responsible for filtering dust from the air, while the motor 9 drives the rotation of the main shaft 33, which in turn rotates the scraper 30, effectively scraping away dust from the inner wall of the filter plate 29 and causing it to fall into the annular dust collection trough 32 for regular cleaning.

[0051] In addition, to enhance the heat dissipation effect, motor 9 can also drive bevel gear 21 to rotate, and then through the transmission of bevel gear 20 and transmission rod 13, the L-shaped air blower 4 and L-shaped return air duct 14 can rotate in opposite directions. This allows users to adjust the position of the L-shaped air blower 4 and L-shaped return air duct 14 as needed, and can also control them to swing back and forth, thereby creating air turbulence inside the distribution cabinet, further improving the heat dissipation effect, and ensuring the stable operation of electrical components inside the distribution cabinet.

[0052] An additional adjustable mounting component allows the user to separate magnet 36 and magnet 37 by moving the mounting plate 16, and the weight of the mounting plate 16 provides stable support on the support base 17. The fixed connection structure of the arc-shaped telescopic rod 39 ensures the horizontal stability of the mounting plate 16, meeting the installation requirements of electrical components. When the mounting plate 16 needs to be folded, the motor 24 drives the lead screw 18 to rotate, adjusting the position of the support base 17, and then the mounting plate 16 is flipped upwards and abuts against the inclined surface 38. The magnetic attraction of magnets 36 and 37, along with the weight of the mounting plate 16 itself, ensures the folding stability of the mounting plate 16.

[0053] In summary, the double-layer adjustable distribution cabinet of the present invention has optimized the ventilation and heat dissipation effect and the adjustment flexibility of the mounting plate 16, ensuring the stability and reliability of the electrical components inside the distribution cabinet and improving the overall operating efficiency.

[0054] The control, model, and circuit connection of each component are not specifically limited, and can be flexibly configured in practical applications. The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this invention does not involve improvements to the software and methods.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
