Abstract
Description
Technical Field
[0001] This application relates to the field of new energy technology, and more specifically, to a power distribution cabinet for new energy applications. Background Technology
[0002] New energy refers to energy obtained through non-traditional, renewable, or low-carbon means, mainly including solar energy, wind energy, hydropower, and biomass energy.

[0003] New energy distribution cabinets are power distribution equipment specifically designed for new energy power generation systems. They are mainly used for the distribution and management of electricity in renewable energy power generation projects such as solar and wind power. New energy distribution cabinets can improve the efficiency and reliability of power generation systems and ensure that new energy power is safely and stably transmitted to the power grid or load end. They are an important supporting equipment in the field of new energy.
[0004] In actual use, the inside of the distribution cabinet contains a variety of metal components and insulating materials. Metal components such as copper busbars, terminals and screws will have a thickened oxide film on the conductor surface under the combined action of moisture and oxygen, which will increase the contact resistance and cause local overheating or even burnout. Meanwhile, insulating materials will gradually age when exposed to a humid environment for a long time. After absorbing moisture, the insulation resistance will decrease, which may cause leakage or breakdown, endangering personal safety. Therefore, it is necessary to improve and optimize them.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0029] like Figures 1 to 8 As shown, the new energy power distribution cabinet provided in this application includes a power distribution cabinet 1. A display panel 11 is provided on the front side of the power distribution cabinet 1. A cabinet door 12 is rotatably installed on the front side of the power distribution cabinet 1. An installation frame 13 is provided inside the power distribution cabinet 1. A heat dissipation base 2 is fixedly installed at the bottom of the power distribution cabinet 1. Ventilation openings 21 are provided on both the left and right sides of the heat dissipation base 2. A shell 22 is fixedly installed inside the heat dissipation base 2. A fan blade 23 is rotatably installed inside the shell 22. A first motor 24 is installed inside the shell 22. The output shaft of the first motor 24 is fixedly connected to the fan blade 23.
[0030] A drying mechanism 3 is provided at the bottom of the outer casing 22. The drying mechanism 3 includes a drying cylinder 31 fixedly installed at the bottom of the outer casing 22. A cylinder cover 32 is rotatably installed on the front side of the drying cylinder 31. Ventilation holes 33 are provided on the outer walls of both the drying cylinder 31 and the cylinder cover 32. Multiple sets of partitions 37 are fixedly installed inside the drying cylinder 31, and a silicone ball is placed between every two sets of partitions 37. It should be noted that the bottom of the outer casing 22 is not closed.
[0031] When using this device, the operator first installs the electrical components inside the distribution cabinet 1 using the mounting bracket 13. After closing the cabinet door 12, the operator starts the first motor 24 through the distribution cabinet 1. The operation of the first motor 24 drives the fan blades 23 to rotate. The rotation of the fan blades 23 draws in cool air from the outside through the vent 21 into the heat dissipation base 2. Subsequently, the air enters the drying cylinder 31 through the ventilation hole 33. The moisture contained in the air is further removed by the silica gel balls in the partition 37. After the moisture absorption treatment, the dry air is discharged into the distribution cabinet 1 through the fan blades 23, achieving heat dissipation while ensuring the dryness inside the distribution cabinet 1. It should be noted that the main component of silica gel is silicon dioxide (SiO2), which has a highly developed microporous network structure with a pore size of about 2-3 nanometers. This structure gives it a very large specific surface area of up to 700-800 m² / g, which can capture a large number of water molecules through physical adsorption.
[0032] The operation of the first motor 24 allows cold air from the outside to enter the interior of the distribution cabinet 1 through the vent 21 and the drying cylinder 31. Before entering the distribution cabinet 1, the air comes into contact with the movable silicone balls inside the multiple sets of partitions 37. The material properties of the silicone balls complete the dehumidification of the air. Compared with traditional devices, this device increases the contact area between the air and the material by agitating the dehumidifying material, effectively preventing the precision components inside the distribution cabinet 1 from being affected by moisture and improving the service life of the components inside the distribution cabinet 1.
[0033] The drying cylinder 31 has a rotatable disturbance rod 38 rotatably installed inside, which is located between every two sets of partitions 37. The outer shell 22 has a rotatable worm gear 35 rotatably installed inside, which is fixedly connected to the disturbance rod 38. The outer shell 22 has a rotatable worm 36 rotatably installed inside, which is drivenly connected to the worm gear 35. The outer wall of the outer shell 22 has a second motor 34 fixedly installed on it, and the output shaft of the second motor 34 is fixedly connected to the worm 36.
[0034] During the heat dissipation operation, the second motor 34 operates, which drives the worm gear 36 to rotate. The worm wheel 35 then begins to rotate slowly. As the worm wheel 35 rotates, the disturbance rod 38 disturbs the silicone balls in the partition 37, increasing the contact area between the silicone balls and the air. This also prevents the silicone balls from depositing, ensuring that the silicone balls can be fully utilized.
[0035] A shelf 14 is fixedly installed on the rear side of the cabinet door 12, and a drying board 15 is placed inside the shelf 14.
[0036] By designing the drying plate 15 inside the rack 14, the drying plate 15 can absorb the moisture already present inside the distribution cabinet 1 after the cabinet door 12 is closed, thereby improving dehumidification efficiency.
[0037] The heat dissipation base 2 has a maintenance mechanism 5 on its front side. The front side wall of the maintenance mechanism 5 has a limit groove 53, and a maintenance door 51 is movably installed inside the limit groove 53.
[0038] By moving the inspection door 51 within the limit groove 53, the inspection mechanism 5 can be closed or opened, thereby allowing the components inside the heat sink base 2 to be inspected through the inspection mechanism 5, such as replacing the silicone balls inside the drying mechanism 3.
[0039] The right end of the inspection door 51 is fixedly equipped with a first magnetic block 52, and the right end of the limiting groove 53 is fixedly equipped with a second magnetic block 54. The first magnetic block 52 and the second magnetic block 54 are magnetically attracted to each other.
[0040] The first magnetic block 52 and the second magnetic block 54 secure the inspection door 51. When the silicone ball needs to be replaced, the operator can pull the inspection door 51 to the left, separating the first magnetic block 52 and the second magnetic block 54, and further moving the inspection door 51 to the left along the limiting groove 53 to open it. The design of the first magnetic block 52 and the second magnetic block 54 allows the operator to easily open and close the inspection door 51.
[0041] The drying cylinder 31 and the cylinder cover 32 are fixed together by a fixing mechanism 4;
[0042] The fixing mechanism 4 includes telescopic grooves 42 opened at the upper and lower ends of the cylinder cover 32. Fixing heads 41 are movably installed inside the two sets of telescopic grooves 42. The fixing heads 41 and the telescopic grooves 42 are elastically connected by springs 43.
[0043] When replacing the silicone balls, the operator can pull the cap 32 outwards, causing the fixing head 41 to be pressed into the telescopic groove 42, thus opening the cap 32. After replacement, the operator closes the cap 32 and the drying cylinder 31. During the closing process, the fixing head 41 is also pressed into the telescopic groove 42 by the outer wall of the drying cylinder 31. The fixing head 41 will then be reset by the elastic potential energy of the spring 43, causing the end of the fixing head 41 to abut against the drying cylinder 31, completing the fixation.
[0044] The drying cylinder 31 has fixing grooves 44 on both the upper and lower sides. One end of the fixing head 41 is dome-shaped, and the dome-shaped end of the fixing head 41 abuts against the fixing groove 44.
[0045] When replacing the silicone balls, the operator can pull the cap 32 outward. Due to its dome-shaped shape, the fixing head 41 is pressed into the telescopic groove 42 by the fixing groove 44, allowing the operator to open the cap 32. After replacement, the operator closes the cap 32 and the drying cylinder 31. During closure, the fixing head 41 is again pressed into the telescopic groove 42 by the outer wall of the drying cylinder 31. However, once the telescopic groove 42 and the fixing groove 44 are aligned, the fixing head 41 returns to its original position using the elastic potential energy of the spring 43, causing the dome-shaped end of the fixing head 41 to abut against the fixing groove 44, thus completing the fixation.
[0046] The design of the fixing head 41 and the fixing groove 44 allows the operator to open and close the drying cylinder 31 simply by pulling it outward or snapping it inward when needed. This makes it quick and easy for the operator to replace the moisture-absorbing material, reducing their workload.
[0047] The working principle and usage process of this application:
[0048] When using this device, the operator first installs the electrical components inside the distribution cabinet 1 using the mounting bracket 13. After closing the cabinet door 12, the operator starts the first motor 24 and the second motor 34 through the distribution cabinet 1. The operation of the first motor 24 drives the fan blades 23 to rotate. The rotation of the fan blades 23 draws in cool air from the outside through the vent 21 into the heat dissipation base 2. Subsequently, the air enters the drying cylinder 31 through the vent 33. The moisture in the air is further removed by the silica gel balls in the partition 37. After moisture removal, the dry air is discharged into the distribution cabinet 1 through the fan blades 23. During the heat dissipation operation, the second motor 34 operates simultaneously, driving the worm gear 36 to rotate. The worm wheel 35 then begins to rotate slowly. As the worm wheel 35 rotates, the disturbance rod 38 agitates the silica gel balls in the partition 37, increasing the contact area between the silica gel balls and the air. This also prevents the silica gel balls from depositing, ensuring that they are fully utilized and achieving heat dissipation while keeping the inside of the distribution cabinet 1 dry. When replacing the silicone balls, the operator can pull the cap 32 outward. Due to its dome-shaped shape, the fixing head 41 is pressed into the telescopic groove 42 by the fixing groove 44, allowing the operator to open the cap 32. After replacement, the operator closes the cap 32 and the drying cylinder 31. During closure, the fixing head 41 is again pressed into the telescopic groove 42 by the outer wall of the drying cylinder 31. However, once the telescopic groove 42 and the fixing groove 44 are aligned, the fixing head 41 returns to its original position using the elastic potential energy of the spring 43, causing the dome-shaped end of the fixing head 41 to abut against the fixing groove 44, thus completing the fixation.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
