Description

A moisture-proof and waterproof distribution cabinet

[0001] The present invention relates to a power distribution cabinet, in particular to a moisture-proof and waterproof power distribution cabinet, belonging to the technical field of power distribution cabinets.

[0002] The distribution cabinet is the final equipment of the power distribution system. It connects the electric energy from the incoming line, and then distributes it to various electrical equipment through different branches, switches, circuit breakers and other equipment to ensure the safe and stable distribution of electric energy to meet the power needs of various systems. At the same time, by controlling switches, circuit breakers and other equipment, it can realize the opening, closing, adjustment and other operations of various electrical equipment, thereby avoiding electrical overload, short circuit and other faults. The distribution cabinet can monitor the operating status of the electrical system by installing electricity meters, ammeters, voltmeters and other equipment to help staff understand and grasp the operation of the system in a timely manner. It can also manage the power supply by segmentation and classification, which is convenient for segmented inspection during line maintenance, avoiding the impact of large-scale power outages on life.

[0003] However, traditional distribution cabinets are all rectangular structures and occupy a large area, especially the distribution cabinets on both sides of the road. Once it rains, a large amount of rainwater will accumulate on the distribution cabinet, causing the distribution cabinet to be damp, which may cause a short circuit. Traditional distribution cabinets do not have a water removal structure, so the possibility of moisture on the surface of the distribution cabinet cannot be avoided. The surface of the distribution cabinet is in a wet state for a long time and combines with oxygen in the air to cause oxidation, and its service life will be greatly reduced.

[0028] 1. The columnar distribution cabinet adopts a columnar vertical design, which makes full use of the vertical space and effectively reduces the floor space. In addition, the internal structure of the columnar distribution cabinet is reasonably designed, making the layout of cables and lines clearer, which is convenient for maintenance personnel to inspect and maintain.

[0029] 2. When the metal driving ring slides on the outer side of the cylindrical distribution cabinet, the sponge water-absorbing ring on the metal driving ring will absorb the moisture on the outer side of the cylindrical distribution cabinet, reducing the situation where rainwater stays on the outer side of the cylindrical distribution cabinet for a long time and causes corrosion to the outer shell of the cylindrical distribution cabinet. After the sponge water-absorbing ring enters the interior of the water-squeezing mechanism, it is squeezed by the water-squeezing trough.

[0030] 3.

The semiconductor refrigeration plate can absorb the heat inside the cylindrical distribution cabinet through the heat absorption surface of the refrigeration plate and dissipate the heat to the inside of the heat storage bin through the heat dissipation surface of the refrigeration plate, thereby achieving the purpose of heat dissipation inside the cylindrical distribution cabinet. During the heat dissipation process, the entire cylindrical distribution cabinet is still in a sealed state, which improves the heat dissipation efficiency and the overall sealing of the device, while achieving the purpose of waterproofing and moisture-proofing.

[0042] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0043] As shown in Figure 9, the moisture-proof and waterproof distribution cabinet provided in this embodiment includes a columnar distribution cabinet 1 and a dehumidification device 2 slidably arranged on the outer side of the columnar distribution cabinet 1. The columnar distribution cabinet 1 adopts a columnar vertical design, which makes full use of the vertical space and effectively reduces the floor space, which makes it particularly suitable for environments with limited space, such as factory workshops, offices, commercial buildings, intersections, etc., and the internal structure of the columnar distribution cabinet 1 is reasonably designed, so that the arrangement of cables and lines is clearer, which is convenient for maintenance personnel to inspect and maintain, and can be expanded according to actual needs. When the power demand increases, it can be met by adding modules or upgrading equipment without replacing the entire distribution cabinet. At the same time, the columnar distribution cabinet 1 has a simple and elegant appearance, which can be coordinated with various environments and enhance the overall aesthetics. Its applicability should be evaluated according to actual needs and scenarios. In order to ensure the safe, stable and efficient operation of the power system, the dehumidification device 2 includes a driving mechanism 3 and a dehumidification mechanism 4. The dehumidification mechanism 4 includes a metal driving ring 401 and a sponge water-absorbing ring 402 fixedly arranged on the outer side of the metal driving ring 401. The sponge water-absorbing ring 402 is against the outer side of the columnar distribution cabinet 1. When it is rainy outdoors, more moisture will adhere to the outer side of the columnar distribution cabinet 1. The columnar distribution cabinet 1 will oxidize in the presence of water and oxygen in the air, thereby corroding the columnar distribution cabinet 1, thereby reducing the service life of the columnar distribution cabinet 1. As the corrosion intensifies, once water enters the interior of the columnar distribution cabinet 1, it will cause immeasurable losses. Therefore, the dehumidification mechanism 4 on the outer side of the columnar distribution cabinet 1 can timely remove moisture, prevent the columnar distribution cabinet 1 from being oxidized as much as possible, and improve the service life of the columnar distribution cabinet 1.

[0044] A water squeezing mechanism 5 corresponding to the dehumidification mechanism 4 is fixedly provided on the outer side surface of the bottom of the cylindrical distribution cabinet 1. The dehumidification mechanism 4 includes a metal driving ring 401 and a sponge water absorption ring 402 fixedly provided on the metal driving ring 401. When the metal driving ring 401 slides on the outer side surface of the cylindrical distribution cabinet 1, the sponge water absorption ring 402 on the metal driving ring 401 will absorb the moisture on the outer side surface of the cylindrical distribution cabinet 1, thereby reducing the situation where rainwater stays on the outer side surface of the cylindrical distribution cabinet 1 for a long time and causes corrosion to the outer shell of the cylindrical distribution cabinet 1. A water squeezing groove 501 is provided on the water squeezing mechanism 5. The water squeezing groove 501 is a conical structure. A drainage hole 502 connected to the water squeezing groove 501 is provided at the bottom of the water squeezing groove 501. The drainage hole 502 is used to drain seawater. The water on the sponge water-absorbing ring 402 will move downward after the sponge water-absorbing ring 402 absorbs the water. When the sponge water-absorbing ring 402 enters the interior of the water-squeezing mechanism 5, the sponge water-absorbing ring 402 is squeezed by the water-squeezing groove 501 on the water-squeezing mechanism 5. The water on the sponge water-absorbing ring 402 is squeezed out during the squeezing process. Therefore, as the number of cycles increases, the water on the outer side of the columnar distribution cabinet 1 can be completely removed to achieve the effect of water removal. After the water in the sponge water-absorbing ring 402 is squeezed out in the water-squeezing groove 501, it is discharged through the drainage hole 502 at the bottom of the water-squeezing groove 501, and then a new round of water removal operation is carried out. The structure is simple, and there is no need for manual wiping by staff, thereby improving the overall waterproof and moisture-proof effect of the columnar distribution cabinet 1.

[0045] The peripheral side surface of the distribution cabinet support base 6 is provided with a plurality of evenly distributed water squeezing mechanism support arms 601. The outer side surface of the water squeezing mechanism 5 is provided with mounting positioning grooves 503 corresponding to the water squeezing mechanism support arms 601. The water squeezing mechanism support arms 601 are fixedly arranged inside the mounting positioning grooves 503 by fastening bolts 602. The water squeezing mechanism 5 is fixed to the bottom of the cylindrical distribution cabinet 1. At the same time, the water squeezing mechanism 5 is fixed by the water squeezing mechanism support arms 601 on the distribution cabinet support base 6, thereby improving the stability of the water squeezing mechanism 5.

[0046] The dehumidification process is specifically as follows: the driving mechanism 3 includes a driving motor 302 and a driving rod 301, a pushing block 403 is fixedly provided on the metal driving ring 401, the pushing block 403 is screwed together with the driving rod 301 through a thread, and the driving rod 301 is used to vertically push the dehumidification mechanism 4, the driving motor 302 is fixedly provided on the upper side of the cylindrical distribution cabinet 1, the output end of the driving motor 302 is provided with a driving gear 303, and the upper end of the driving rod 301 is fixedly provided with a driven gear 304, and the driving gear 303 is meshed with the driven gear 304. The driving motor 302 is used to rotate the driving rod 301, and the driving motor 302 on the driving mechanism 3 is started to drive the driving gear 303 to rotate. The driving gear 303 drives the driven gear 304 on the driving rod 301 to rotate, and then drives the driving rod 301 to rotate. At the same time as the driving rod 301 rotates, the pushing block 403 connected to the driving rod 301 through a thread drives the dehumidification mechanism 4 to move up and down in a circular motion, so that the sponge water absorption ring 402 on the metal driving ring 401 can absorb moisture from the outer surface of the cylindrical distribution cabinet 1;

[0047] When the driving rod 301 rotates clockwise, the dehumidification mechanism 4 moves downward, and when the driving rod 301 rotates counterclockwise, the dehumidification mechanism 4 moves upward.

[0048] Furthermore, as shown in FIG3 , a transmission rod support block 901 is provided between the driven gear 304 and the driving rod 301 , a transmission hole 902 is provided on the transmission rod support block 901 , the upper end of the driving rod 301 is rotatably connected to the transmission hole 902 , a transmission slot 101 is provided on one side of the cylindrical distribution cabinet 1 , the driving rod 301 is rotatably provided inside the transmission slot 101 , and the pushing block 403 is slidably provided inside the transmission slot 101 , when the driving rod 301 rotates, the transmission hole 902 on the transmission rod support block 901 supports the driving rod 301 , thereby improving the stability of the operation of the driving rod 301 ;

[0049] At the same time, a guide block 404 corresponding to the push block 403 is fixedly provided on the metal driving ring 401. In order to further improve the stability of the movement of the dehumidification mechanism 4, a guide rod 10 is slidably provided inside the guide block 404. The guide rod 10 is fixedly provided on one side of the cylindrical distribution cabinet 1 through the guide rod support block 9. The guide rod support block 9 is fixedly provided on the upper side of the cylindrical distribution cabinet 1. A guide rod 10 is fixedly provided on the other side of the cylindrical distribution cabinet 1. The guide block 404 of the dehumidification mechanism 4 is slidably provided on the guide rod 10 and is fixed to one side of the cylindrical distribution cabinet 1 through the guide rod support block 9, thereby improving the structural strength of the guide rod 10.

[0050] A guide slot 102 corresponding to the transmission slot 101 is provided on one side of the cylindrical distribution cabinet 1. The guide rod 10 is disposed inside the guide slot 102. The drive rod 301 is rotatably disposed inside the transmission slot 101. The guide rod 10 is fixedly disposed inside the guide slot 102. This effectively protects the drive rod 301 or the guide rod 10, thereby extending the service life of the device.

[0051] In addition, as shown in Figure 7, a distribution cabinet support seat 6 is fixedly provided on the bottom side of the cylindrical distribution cabinet 1, and symmetrically distributed dehumidification support arms 603 are provided on the distribution cabinet support seat 6, one of the dehumidification support arms 603 is fixedly connected to the guide rod 10, and the other dehumidification support arm 603 is rotatably connected to the drive rod 301 through a bearing. The drive rod 301 is rotatably set inside the transmission groove 101, so the transmission rod support block 901 plays a certain supporting role on the drive rod 301. At the same time, the bottom of the drive rod 301 is rotatably connected to the dehumidification support arm 603 through a bearing to ensure the stability of the rotation of the drive rod 301. Of course, the bottom of the guide rod 10 is fixedly connected to the other dehumidification support arm 603 to improve the structural strength of the guide rod 10.

[0052] Furthermore, as shown in Figures 4 and 8, a heat dissipation mechanism 7 is fixedly provided inside the cylindrical distribution cabinet 1. A heat storage bin 701 is provided inside the heat dissipation mechanism 7. An air inlet hole 103 is provided inside the transmission slot 101. The transmission slot 101 is connected to the guide slot 102 through the air inlet hole 103, and the heat storage bin 701 is connected to the air inlet hole 103. The heat dissipation mechanism 7 is fixedly provided inside the cylindrical distribution cabinet 1. The heat dissipation mechanism 7 divides the cylindrical distribution cabinet 1 into two parts. Therefore, electrical components can be installed on both sides of the heat dissipation mechanism 7 at the same time, and the electrical components can be classified and arranged, which greatly improves the utilization rate of the space and facilitates the maintenance and maintenance of the components inside the cylindrical distribution cabinet 1.

[0053] During the use of components, they will generate heat due to the thermal effect of the current. Once the heat is too high, the service life of the components will be affected. Therefore, an air inlet hole 103 is opened inside the transmission groove 101 and the guide groove 102. The transmission groove 101 is connected to the guide groove 102 through the air inlet hole 103. At the same time, a heat storage bin 701 is opened inside the heat dissipation mechanism 7. The heat storage bin 701 is connected to the air inlet hole 103. However, the interior of the cylindrical distribution cabinet 1 is still in a sealed state to prevent rainwater from entering the interior of the cylindrical distribution cabinet 1, thereby improving the safety of the device.

[0054] 701 , the heat dissipation device 7 is provided with a cooling plate groove 702 on both sides, and the cooling plate groove 702 is connected to the interior of the heat storage bin 701. A semiconductor cooling plate 703 is fixedly arranged inside the cooling plate groove 702. A cooling plate groove 702 is provided on the heat dissipation device 7, and the cooling plate groove 702 is connected to the interior of the cylindrical power distribution cabinet 1. A semiconductor cooling plate 703 is fixedly arranged inside the cooling plate groove 702. The semiconductor cooling plate 703 includes a cooling plate heat absorbing surface and a cooling plate heat dissipating surface. The cooling plate heat absorbing surface is arranged on the outer side of the heat dissipation device 7, and the cooling plate heat dissipating surface is arranged on the inner side of the heat dissipation device 7. Therefore, the semiconductor cooling plate 703 can absorb the heat inside the cylindrical power distribution cabinet 1 through the cooling plate heat absorbing surface and dissipate the heat to the interior of the heat storage bin 701 through the cooling plate heat dissipating surface, thereby achieving the purpose of heat dissipation inside the cylindrical power distribution cabinet 1. However, during the heat dissipation process, the entire cylindrical power distribution cabinet 1 is still in a sealed state, which improves the heat dissipation efficiency and the overall sealing of the device, while achieving the purpose of waterproofing and moisture-proofing.

[0055] Since the heat storage bin 701 is connected to the external environment, a drainage slope 704 is fixedly provided at the bottom of the heat storage bin 701 to prevent rainwater from staying inside the heat storage bin 701. Once rainwater enters the heat storage bin 701, it will be drained through the drainage slope 704 inside the heat storage bin 701, thereby extending the service life of the device and achieving the purpose of waterproofing and moisture-proofing.

[0056] In addition, as shown in Figure 7, the bottom of the water-squeezing mechanism support arm 601 is fixedly provided with an auxiliary supporting foot 604, and the bottom of the distribution cabinet support base 6 is fixedly provided with a main supporting foot 605. The bottoms of the auxiliary supporting foot 604 and the main supporting foot 605 are connected with cement piles. The bottom of the columnar distribution cabinet 1 is not directly fixed on the cement pile. The reason is that when the rain is too heavy and causes a certain amount of water squeezing, a small amount of rainwater will accumulate on the upper side of the cement pile, which will have a certain impact on the columnar distribution cabinet 1. Therefore, a distribution cabinet support base 6 is fixedly provided at the bottom of the columnar distribution cabinet 1, and the distribution cabinet support base 6 is fixed to the cement pile, that is, the columnar distribution cabinet 1 is lifted to a certain height away from the ground to improve the waterproof and moisture-proof performance to a certain extent, and then the columnar distribution cabinet 1 is further lifted by the auxiliary supporting foot 604 and the main supporting foot 605 at the bottom of the distribution cabinet support base 6;

[0057] Furthermore, as shown in Figures 2 and 6, the outer side of the cylindrical distribution cabinet 1 is provided with symmetrically distributed door body grooves 104, and the interior of the door body groove 104 is connected to the door body 11 by a hinge rotation, and a sealing rubber ring is provided between the door body 11 and the door body groove 104. Two door body grooves 104 are provided on the cylindrical distribution cabinet 1, and the door body 11 is rotatably set on the door body groove 104 and sealed by the sealing rubber ring, which facilitates the installation of components and improves the sealing of the device. The outer sides of the cylindrical distribution cabinet 1 and the door body 11 are sprayed with waterproof paint, which can prevent rainwater from accumulating on the outer side of the cylindrical distribution cabinet 1, thereby improving the overall waterproof performance of the cylindrical distribution cabinet 1;

[0058] As shown in Figure 4, the upper side of the cylindrical distribution cabinet 1 is connected to a protective mechanism 8 through a protective cover support column 801, and a protective cover 802 is provided on the protective mechanism 8. The diameter of the inner side of the protective cover 802 is larger than the outer diameter of the cylindrical distribution cabinet 1. The diameter of the protective cover 802 on the protective mechanism 8 is larger than the diameter of the cylindrical distribution cabinet 1, corresponding to the dehumidification mechanism 4, wherein, when the dehumidification mechanism 4 moves upward, the dehumidification mechanism 4 is arranged inside the protective cover 802. Therefore, when there is no need to dehumidify the outer side of the cylindrical distribution cabinet 1, the dehumidification mechanism 4 can enter the inside of the protective cover 802 and protect the dehumidification mechanism 4 through the protective cover 802, thereby improving the service life of the dehumidification mechanism 4. A fluorescent paint groove 803 is provided on the outer side of the protective cover 802, and the interior of the fluorescent paint groove 803 is sprayed with fluorescent paint, which plays a certain warning role, prevents accidental contact, and improves the service life of the device;

[0059] In addition, as shown in Figures 4 and 6, a processor 12 is fixedly installed inside the protective mechanism 8, and a number of evenly distributed humidity sensors 13 are provided on the outer side of the cylindrical distribution cabinet 1. The humidity sensor 13 and the drive motor 302 are electrically connected to the processor 12 through wires. When the humidity sensor 13 on the cylindrical distribution cabinet 1 detects that the outer side is relatively moist, the information is pushed to the processor 12. The processor 12 processes the information and pushes it to the drive motor 302. After the drive motor 302 is started, it drives the dehumidification mechanism 4 to dehumidify. The structure is simple, the degree of automation is high, and the waterproof and moisture-proof effect is greatly improved.

[0060] As shown in Figure 9, the principles of the moisture-proof and waterproof distribution cabinet provided in this embodiment are as follows:

[0061] The dehumidification mechanism 4 includes a metal driving ring 401 and a sponge water-absorbing ring 402 fixedly mounted on the metal driving ring 401. When the metal driving ring 401 slides on the outer side of the cylindrical distribution cabinet 1, the sponge water-absorbing ring 402 on the metal driving ring 401 absorbs moisture from the outer side of the cylindrical distribution cabinet 1, thereby reducing the possibility of rainwater remaining on the outer side of the cylindrical distribution cabinet 1 for a long time and causing corrosion to the outer shell of the cylindrical distribution cabinet 1.

[0062] The water in the sponge water absorbing ring 402 is squeezed out in the squeezing groove 501 and is discharged through the drainage hole 502 at the bottom of the squeezing groove 501, and then a new round of water removal operation is carried out. The structure is simple and there is no need for manual wiping by the staff, thereby improving the overall waterproof and moisture-proof effect of the cylindrical distribution cabinet 1.

[0063] The heat dissipation mechanism 7 divides the cylindrical power distribution cabinet 1 into two parts, so that electrical components can be installed on both sides of the heat dissipation mechanism 7 at the same time, and the electrical components can be arranged in categories, which greatly improves the utilization rate of space and facilitates the maintenance and repair of the components inside the cylindrical power distribution cabinet 1;

[0064] A cooling plate slot 702 is provided on the heat dissipation mechanism 7, and the cooling plate slot 702 is connected to the interior of the cylindrical distribution cabinet 1, and a semiconductor cooling plate 703 is fixedly arranged inside the cooling plate slot 702. The semiconductor cooling plate 703 can absorb the heat inside the cylindrical distribution cabinet 1 through the cooling plate heat absorption surface and dissipate the heat to the interior of the heat storage bin 701 through the cooling plate heat dissipation surface, thereby achieving the purpose of heat dissipation inside the cylindrical distribution cabinet 1. However, during the heat dissipation process, the entire cylindrical distribution cabinet 1 is still in a sealed state, which improves the heat dissipation efficiency and the overall sealing of the device, while achieving the purpose of waterproofing and moisture-proofing.

[0065] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0066] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0067] The foregoing description shows and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the inventive concept described herein by the teachings above or by techniques or knowledge in the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be within the scope of the appended claims.
