Description

Technical Field

[0001] This invention belongs to the field of power distribution cabinet technology, and particularly relates to a rainproof and moisture-proof power distribution cabinet. Background Technology

[0002] A distribution cabinet is a general term for a motor control center, which includes power distribution cabinets, lighting distribution cabinets, and metering cabinets. It is the final stage equipment in a power distribution system. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit in the previous stage of power distribution equipment to the nearest load, and this level of equipment should provide protection, monitoring, and control for the load.

[0003] In many situations, distribution cabinets need to be installed outdoors in sparsely populated areas. These cabinets typically house precision electrical components, so the temperature and humidity of the installation environment significantly affect these components, potentially causing short circuits and damage. Existing outdoor distribution cabinets are generally not rainproof or moisture-proof, making them highly susceptible to external environmental influences. In heavy rainfall, water can leak through gaps, increasing internal humidity and affecting normal operation. Furthermore, rain splashes can impact the overall performance of the distribution cabinet depending on the rainfall scenario. To address these issues, a seepage-proof and moisture-proof distribution cabinet (patent number: CN202311192) has been published by the State Intellectual Property Office. 485.4}, which includes a cabinet, air inlet, first air outlet, second air outlet, rain cover, rainproof device, moisture-proof device, etc., although it can solve the problem of leakage and high humidity in existing distribution cabinets during rainy and snowy weather, it still has certain drawbacks: On the one hand, the operation of the above-mentioned equipment is completed by motors. Their placement in the distribution cabinet may not only affect the normal operation of other electrical components in the cabinet, but also increase the burden on the equipment during use. On the other hand, there are many exposed components of the above-mentioned devices, which are also susceptible to erosion by rainwater, causing inconvenience during operation. At the same time, the arrangement of multiple structures is relatively cumbersome and complex, the operating burden is heavy, and it is inconvenient to carry out the rainproof process, which cannot effectively meet the usage requirements.

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0033] Example 1, such as Figures 1 to 11As shown, a rainproof and moisture-proof distribution cabinet includes a cabinet body 1. The upper half of the cabinet body 1 is designed in the shape of a right-angled trapezoid with curved sides. A matching curved cabinet door is also provided at this location. The cabinet door is designed to open vertically, providing good airflow during use and ensuring usability. The lower half of the cabinet body 1 is designed in the shape of a frustum, which provides a prerequisite for its moisture resistance, especially by increasing the installation height of electrical components and reducing the possibility of moisture intrusion. A rainproof mechanism integrating rain protection and rainwater drainage is provided at the top of the cabinet body 1. The rainproof mechanism includes components located above the cabinet body 1. The drainage component 3 at the geometric center can collect a certain amount of rainwater and discharge it outwards, providing sufficient rainwater resources for subsequent rainwater reuse components and ensuring the effective generation of driving power. A conical truncated hood 2 is connected to the outside of the drainage component 3. The material of the hood 2 is similar to that of the rainproof cloth 312 installed in the drainage component 3, providing good rainproof performance and allowing for slight deformation as needed to enable the operation of the drainage component 3, improving the functionality of the equipment. A semi-circular cross-section water collection strip 4 is located at the lower end of the hood 2 to collect and store a certain amount of rainwater. A conical ring is located above the outer side of the water collection strip 4. The splash guard 41 serves two purposes: firstly, it guides rainwater outward to prevent it from splashing; secondly, it limits the flow of rainwater when the drainage assembly 3 discharges the water, ensuring effective driving force. A liquid level sensor 5 is installed inside the splash guard 41. At least two liquid level sensors 5 are installed: one to detect the low water level in the water collection strip 4, and the other to detect the high water level. To ensure effective operation of the equipment, a control device can be installed in the power distribution cabinet to receive signals from the liquid level sensors 5 and control the convenient discharge of water from the water collection strip 4. Specifically, the high-level liquid level sensor 5... The system is used to detect the amount of rainwater in the area formed by the water collection strip 4, the splash guard 41, and the collection cover 2. When the water level reaches the maximum storage capacity, a signal is sent to the control device. The control device receives the signal and controls the solenoid valve 852 to open, thus allowing the rainwater to be discharged. When the low-level liquid level sensor 5 detects that the water level is lower than the detection position, a signal is sent to the control device. The control device receives the signal and controls the solenoid valve 852 to close, waiting for the subsequent rainwater to be replenished. Of course, the control process when the rainwater level is low can also be controlled together with the drainage component 3, that is, to make the drainage component 3 operate to discharge the temporarily stored rainwater, so as to ensure the continuous operation of the rainwater reuse component.Below the collection covers 2 on both sides of the distribution cabinet body 1, a rainwater recycling component with moisture-proof function is installed. The rainwater recycling component includes a mounting bracket 6. A rainwater drive component 8 is installed on one side of the mounting bracket 6 to collect rainwater and convert it into driving power. A water guiding component 7 is installed below the rainwater drive component 8. A longitudinal air diffuser component 9 is installed on one side of the rainwater drive component 8. A vertical air supply component 10 is installed below the longitudinal air diffuser component 9. A diversion cover 11 is installed on the outside of the distribution cabinet body 1 corresponding to the vertical air supply component 10, and its lower part extends into the distribution cabinet body 1 and is connected to its lower half. A moisture-proof ventilation component 12 is installed at the lower part inside the distribution cabinet body 1. Specifically, the rainwater recycling component is... The rainwater received at the drainage component 3 is converted into kinetic energy during its fall, and then applied to the rainwater drive component 8. The rainwater that has completed the kinetic energy conversion is discharged by the water guide component 7, away from the main body of the distribution cabinet 1. After receiving the driving power, the rainwater drive component 8 will act on the longitudinal ventilation component 9 and the vertical ventilation component. The longitudinal ventilation component 9 can spray water vapor in the longitudinal direction of the distribution cabinet, reducing the possibility of water vapor intruding into the equipment components. The operation of the vertical ventilation component can be fed back to the distribution cabinet through the diversion hood 11, especially introduced to the moisture-proof ventilation component 12, to achieve the horizontal spraying of water vapor at the bottom of the distribution cabinet, ensuring the use effect, greatly improving the functionality of the device and meeting the use requirements.

[0034] In the above process: the drainage component 3 can collect a certain amount of rainwater and discharge it outwards, providing sufficient rainwater resources for the subsequent rainwater reuse component and ensuring the effective generation of driving power; the rainwater reuse component utilizes the gravitational potential energy of the falling rainwater to convert it into kinetic energy and apply it to the rainwater drive component 8, enabling the longitudinal air distribution component 9 and the vertical air supply component 10 to operate smoothly, providing convenient conditions for the moisture-proof performance of the cabinet. Furthermore, the structure of each device is simple, and the working principle is easy to implement, reducing the operating burden to a certain extent, saving costs, and ensuring usage requirements. This device is reasonably designed, simple in structure, easy to process, and can reduce the complexity of equipment components, making it simple and convenient. It collects rainwater during rainfall and reacts it to the distribution cabinet to achieve moisture-proof performance. At the same time, it can save power resources to a certain extent, reduce the burden on the distribution cabinet during operation, and improve the functionality of the equipment to meet usage requirements while achieving cost reduction and efficiency improvement.

[0035] To facilitate rainwater collection and direct it to the collection strip 4, the drainage component 3 includes a concave frame 31. A rotating shaft 32 is housed within the concave frame 31. A drive wheel 33 is located on one side of the rotating shaft 32. This drive wheel 33 is driven by a motor. There are two drive wheels 33, each capable of receiving driving power. To ensure effective drainage, the driving power received by the two drive wheels 33 is reversed. A drive plate 34 is located on the other side of the rotating shaft 32. An L-shaped support rod 35 is located on one side of the drive plate 34. The short side of the support rod 35 is cylindrical, while the long side is key-shaped. On the one hand, it facilitates the connection of multiple support rods 35, and on the other hand, it ensures the smoothness of the linkage rotation adjustment process. The multiple support rods 35 are arranged in a ring from the outside to the geometric center of the concave frame 31 with the pivot 32 as the center. Two sets are arranged in a mirror image of the concave frame 31. A concave connecting frame 36 is set between the two support rods 35 near the geometric center of the concave frame 31. The concave part of the connecting frame 36 is cylindrical. A first connecting rod 37 is set on the outside of the support rod 35. The connection between the two is a rotatable connection. A top rod 39 is set above the first connecting rod 37. The connection between the two is a hinge. A second connecting rod 38 is set at the cylindrical part of the connecting frame 36. A lifting rod 310 is set at the end of the second connecting rod 38. The top rod 39 and the lifting rod 310 are connected. The 10th lifting rod can slide vertically relative to the concave frame 31. Above the top rod 39, which is a mirror image of the concave frame 31, are ring frames 311. The diameters of multiple ring frames 311 decrease sequentially from the outside in. For example, the outermost ring frame 311 is connected to two outermost top rods 39. Multiple ring frames 311 are sequentially installed inwards. Between adjacent ring frames 311, a rainproof cloth 312 with bending and folding properties is installed. The protective cloth is generally cut in a ring shape, and the inner diameter of multiple rainproof cloths 312 gradually increases from the middle to the outside. The inner and outer circles of the cloths are fixedly connected to the ring frames 311 to ensure stability and prevent leakage. The end of the lifting rod 310 is equipped with a top ball 313, which connects to the top... An adapter cover 314 is provided above the ring frame 311 corresponding to ball 313. The top ball 313 rises under the drive of the lifting rod 310, and when it reaches its highest position, it acts on the adapter cover 314 to ensure thorough rainwater drainage. Specifically, during use, the rotating shaft 32 receives the driving power, which drives the drive plate 34, each frame rod 35, and the connecting frame 36 to rotate around the rotating shaft 32. With the lifting rod 310 as the boundary, the left and right ring frames 311 rotate in the same manner, causing the rainproof cloth 312 to rise and fall in a wave-like motion. When the middle ring frame 311 is in the lowest position, the drainage component 3 is in the rainwater receiving state. During operation, each ring frame 311 is slowly lifted outwards from the center.The stored rainwater is then directed outwards and collected at the water collection strip 4, facilitating the generation of subsequent driving power and ensuring usage needs are met. This design is simple and convenient to operate, with a straightforward and uncomplicated structure and strong functionality.

[0036] To ensure that rainwater discharged through the drainage component 3 can be reused during its fall, and especially to generate driving power, the rainwater driving component 8 includes a crossbeam 81 connected to the mounting bracket 6. A rotating disk 82 is provided at the end of the crossbeam 81. Two sets of rotating disks 82 are provided, one for stable support of the rotating bucket 83, and the other for facilitating the rotation of the bucket 83 relative to the rotating disk 82. The rotating bucket 83 is housed inside the rotating disk 82, and a vortex fan blade 84 is installed inside the bucket 83. An upper rotating sleeve 85 is located above the bucket 83, and a water inlet pipe 851 is located above the upper rotating sleeve 85, extending into the water collection strip 4. A solenoid valve 852 is installed on the water inlet pipe 851. A lower rotating sleeve 86 is located below the bucket 83 and connected to the water guiding component 7. Both the upper rotating sleeve 85 and the lower rotating sleeve 86 are stably supported. The fixed placement allows the rotating drum 83 to rotate relative to both, thus not affecting the entry and exit of rainwater while ensuring the generation of power during the rainwater's descent. Specifically, when the liquid level sensor 5 detects that the amount of rainwater in the water collection strip 4 has reached the maximum storage capacity, it sends a signal to the control device. The control device receives the signal and controls the solenoid valve 852 to open. At this time, the rainwater in the water collection strip 4 falls and is transported to the rotating drum 83 through the water inlet pipe 851, which then acts on the vortex fan blade 84. The rotation of the vortex fan blade 84 will drive the rotating drum 83 to rotate circumferentially, thus generating driving power. An active wheel 87 is also provided on the upper outer side of the rotating drum 83. The active wheel 87 will also rotate with the rotating drum 83 and apply driving power to the longitudinal air diffuser assembly 9, providing convenient conditions for the subsequent realization of the moisture-proof function.

[0037] To convert the gravity and flow of rainwater falling through the four water collection points into driving power, a positioning frame 831 is installed inside the rotating drum 83. A shaft 832 is installed inside the positioning frame 831 and connected to the vortex fan blade 84. This design allows the vortex fan blade 84 to rotate together with the rotating drum 83. To ensure that the power generation is achieved through water flow, the vortex fan blade 84 includes a double-conical frustum-shaped blade body 841. An L-shaped blade plate 842 is installed on the outer side of the blade body 841. A blade plate 842, centrally symmetrical to the upper blade plate 842, is installed on the lower half of the blade body 841. The two blade plates 842 correspond to each other and are designed in a double S-shape. The upper end of the upper blade plate 842 rotates outward into an arc shape, which can support the upper rotating sleeve 85. The rainwater left behind, upon impact with the blades 842, tends to rotate, causing the rainwater to fall smoothly. Between adjacent blades 842, a Z-shaped streamlined baffle 843 is positioned. When the rainwater falls to the middle of the upper blades 842, the baffle 843 separates and transports the rainwater, optimizing its path and significantly increasing driving force. As the rainwater flows down to the lower blades 841, the baffle 843 no longer separates the water at its end; instead, the two streams converge and further act on the lower blades 842, providing further drive. Thus, multiple blades 842 rotate due to the falling water, generating driving force and acting outwards, enabling resource reuse and ensuring operational needs are met.

[0038] To facilitate the centralized drainage of collected rainwater, the water guiding component 7 includes a Z-shaped drain pipe 71 connected to the lower rotating sleeve 86. A drain cover 72 is installed below the drain pipe 71. Specifically, rainwater falling from the rotating bucket 83 is first collected by the lower rotating sleeve 86 and then guided into the drain pipe 71. Relying on the established drain pipe 71, the rainwater is finally discharged through the drain cover 72, thus completing the centralized drainage of rainwater to the outside, reducing the possibility of it flowing near the cabinet, and preventing rainwater from damaging the cabinet, thereby improving its functionality. Of course, a water guiding trough can be set up at the cabinet location corresponding to the drain cover 72 as needed to further ensure the practicality of the distribution cabinet.

[0039] To ensure good rain and moisture protection at the top of the distribution cabinet body 1, the longitudinal air diffuser assembly 9 includes a housing 91 connected to the crossbeam 81. A mounting base 92 is located at the top of the housing 91, and a rotating rod 93 is located within the mounting base 92. A driven wheel 94 is located on the outer side of the rotating rod 93. A synchronous belt 95 is located between the driving wheel 87 and the driven wheel 94. A first worm gear 96 is located below the rotating rod 93, with a first worm wheel 97 on one side of the first worm gear 96. Longitudinal rods 98 are located on both sides of the first worm wheel 97. A limiting sleeve can be provided inside the housing 91 outside the longitudinal rods 98 to ensure stability and smoothness during rotation. Two longitudinal fans 99 are located at the ends of the longitudinal rods 98, located on either side of the first worm wheel 97, to achieve comprehensive air blowing during rotation. Specifically, the rainwater drive assembly 8 rotates during heavy rainfall, causing the driving wheel 87 to rotate. 7. As it rotates, the driving power can be applied to the driven wheel 94 by means of the established synchronous belt 95, causing the rotating rod 93 to rotate with the first worm 96. During this process, the driving power is transmitted to the longitudinal fan 99 through the cooperation of the first worm 96 and the first worm wheel 97, so that the longitudinal fan 99 is rotated on both the front and rear sides in the longitudinal direction. At the same time, the fan blades blow water vapor and other substances outward, reducing the possibility of interference. Furthermore, the vertical air supply assembly 10 includes a connecting rod 101 connected to the first worm 96. A vertical fan 102 is provided below the connecting rod 101. The driving power during the rotation of the first worm 96 will act on the connecting rod 101, causing it to drive the vertical fan 102 to rotate and the air force will act on the diffuser shroud 11. In this way, the air force will be fed back to the distribution cabinet, especially promoting the moisture protection of the bottom of the cabinet. The device is reasonably designed and highly practical.

[0040] To ensure the effective use of the distribution cabinet body 1, the moisture-proof ventilation component 12 includes a partition 121 located in the lower half of the cabinet body 1. A horizontal plate 122, inclined on one side of the partition 121, is also provided inside the cabinet body 1 above the partition 121 and the horizontal plate 122. This ensures the stable placement of the electrical components within the cabinet. To further improve the moisture-proof performance, conventional techniques such as filling the gap between the support plate and the horizontal plate 122 can be used. This ensures the integrity of the cabinet structure and provides supplementary moisture protection, thereby enhancing its functionality. Furthermore, one side of the horizontal plate 122 is connected to the upper side of the lower end of the diversion shroud 11. Below the horizontal plate 122, an L-shaped guide plate 123 is provided. One side of the guide plate 123 is connected to the lower side of the lower end of the diversion shroud 11. The L-shaped area between the guide plate 123 and the horizontal plate 122 corresponds to the flow channel in the diversion shroud 11, serving to receive the generated wind force. At the gaps corresponding to the guide plate 123 and the partition plate 121, ventilation holes 1a are provided below the distribution cabinet body 1. The four sets of ventilation holes 1a are centrally symmetrical about the lower geometric center of the distribution cabinet body 1. The two diversion shrouds 11 on the left and right sides... The generated airflow can be directed and discharged towards the ventilation hole 1a. A cross-shaped airflow guide block 124 is provided on the lower end face of the distribution cabinet body 1. The corner of the airflow guide block 124 near the ventilation hole 1a is arc-shaped. Air outlets 1b are provided on both sides of the lower part of the distribution cabinet body 1 corresponding to the airflow guide block 124. By utilizing the airflow guide block 124, the airflow path is optimized, directing the airflow towards the air outlet 1b. This achieves airflow to the left and right sides of the distribution cabinet body 1, which to some extent prevents rainwater from damaging the cabinet and ensures safe operation. Effect; In addition, a fan is also provided on the front side of the distribution cabinet body 1 located below the guide plate 123. It can be used in conjunction with the moisture-proof ventilation component 12. When running, it blows air vertically and exhausts it through the rear side of the distribution cabinet body 1. In this way, the lower half of the distribution cabinet has both vertical and horizontal air blowing functions to prevent moisture intrusion and ensure comprehensive and complete moisture protection. Of course, a ventilation hole 1a is provided on the rear side of the distribution cabinet body 1 located above the support plate. A cooling fan can also be provided corresponding to the ventilation hole 1a to solve the heat generated by the electrical components in the cabinet during operation and ensure its stability during operation.

[0041] To ensure the smooth operation of the vertical air supply assembly 10 and effectively improve its uniformity of delivery, a flow equalization plate 111 with a willow leaf arc design is provided on the inner side of the flow divider 11. Four flow equalization plates 111 are arranged sequentially on both sides of the flow divider 11. This design allows the air force to be evenly distributed to both sides of the flow divider 11, so that the air force is fed according to the equipment specifications. Furthermore, two flow equalization plates 111 are arranged in a mirror image and located on the lower side inside the flow divider 11, and play a converging role. The air force traveling along the path inside the flow divider 11 flows from the top to the bottom, and under the action of the flow equalization plate 111 below, the air force is gathered and finally guided to the power distribution cabinet body 1 through the lower side of the flow divider 11. This promotes the moisture-proof performance of the subsequent installation location of the power distribution cabinet and ensures its performance.

[0042] Example 2, as Figures 12-13 As shown, to improve the functionality of the distribution cabinet, another type of distribution cabinet body 1 is provided. The composition of each component is the same as that of the distribution cabinet body 1 mentioned in Embodiment 1. The difference is that a power distribution component 13, which integrates vertical air supply and driving the drainage component 3, is provided on one side of the rainwater drive component 8. The power distribution component 13 includes a hollow, double-ear-shaped placement seat 131 connected to the rainwater drive component 8. A second worm gear 132 is provided inside the placement seat 131. A transmission rod 133 is provided on one side of the second worm gear 132 and connected to the drainage component 3. Second worms 134 are provided on both the front and rear sides of the second worm gear 132, with their lower sides extending into the diversion shroud 11. A power receiving wheel 135 is provided above the second worm 134 to receive the driving power of the rainwater drive component 8. Specifically, the rainwater drive component 8 still receives the rainwater discharged downwards from the water collection strip 4 and rotates. When it rotates, the driving power is applied to the power receiving wheel 135 via the drive wheel 87. The rotation of the power receiving wheel 135 then acts on the two second worm gears 134. On the one hand, the rotation of the second worm gears 134 themselves can drive the vertical air diffuser assembly to operate. On the other hand, the rotation of the two second worm gears 134 will act on the second worm wheel 132. The rotation of the second worm wheel 132 can act on the drainage assembly 3, providing it with driving power. This design can achieve operation without power resources to a certain extent, that is, it mainly relies on the water collecting strip 4 itself to collect rainwater. When the collected water reaches the driving condition, it falls down and gives the rainwater driving assembly 8 driving power, which then acts on the drainage assembly 3 to discharge the rainwater collected by the drainage assembly 3 again. This process is repeated to achieve operation without power resources and save electricity. Of course, this embodiment is applicable to environments with heavy rainfall, and it is necessary to ensure that the rainfall can be supplied in a timely manner to ensure rainproof and moisture-proof performance.
