Description

Technical Field

[0001] This invention relates to the field of electrical control cabinet technology, and in particular to an energy-saving and heat-dissipating smart grid electrical control cabinet. Background Technology

[0002] With the continuous acceleration of the construction of the national new power system and smart grid, and the full implementation of the green and low-carbon energy transformation strategy, the requirements for the intelligence, energy efficiency, and environmental adaptability of electrical control equipment in scenarios such as power grid transmission and distribution, new energy grid connection, industrial and mining enterprise power distribution, and municipal power supply are constantly increasing. As a core basic device in the smart grid distribution system, the electrical control cabinet undertakes important functions such as power line on / off control, load dispatching, operational status monitoring, relay protection, and data interaction and transmission. It is a key carrier for ensuring the safe and stable operation of the power grid and achieving efficient power distribution, and is widely used in various core scenarios such as substations, distribution rooms, new energy power plants, industrial parks, and urban smart power supply networks. Currently, the smart grid is rapidly developing towards large capacity, high integration, distributed grid connection, and intelligent dispatch. The number of power electronic modules, intelligent monitoring elements, and switch control components integrated inside the control cabinet is constantly increasing, the degree of equipment integration is continuously improving, and energy loss and heat generation during operation are showing a normalized upward trend. At the industry level, green design and energy conservation concepts have been fully implemented. Relevant national standards have also made standardized requirements for the energy consumption indicators, heat dissipation adaptability and long-term operational reliability of electrical control cabinets, promoting the iterative upgrading of industry products towards low energy consumption, strong heat dissipation, intelligent control and high protection.

[0003] Chinese patent CN118017386B discloses an energy-saving heat-dissipating power control cabinet. By installing a heat sink and a miniature fan, left and right convection vents are staggered on the side wall of the heat sink. The miniature fan increases the airflow through the heat sink, accelerating air circulation and heat conduction, effectively improving heat dissipation efficiency and reducing equipment temperature. The staggered installation position of the miniature fan on the side wall of the heat sink allows the airflow to cover a wider heat dissipation area, ensuring uniform heat dissipation across the entire surface of the heat sink. A protective box, a heat dissipation top plate, and an eaves ventilation plate are installed. Ventilation is provided inside the protective box through vents, heat dissipation holes, and ventilation holes on the eaves ventilation plate. The heat dissipation holes are located above the eaves ventilation plate, which in turn is above the vents, allowing air inside the protective box to circulate rapidly from bottom to top for heat dissipation. Air entering through the eaves ventilation plate moves upwards, accelerating the rapid discharge of hot air from the heat dissipation top plate through the heat dissipation holes, resulting in better heat dissipation and energy savings.

[0004] While the above methods can improve heat dissipation efficiency and energy saving, they are not ideal for outdoor use in rainy conditions. They struggle to collect rainwater for cooling while simultaneously providing rain protection and ventilation. Air cooling alone is inefficient and can negatively impact the control cabinet's lifespan. Furthermore, conventional air filters accumulate dust and clog the mesh over time, requiring regular manual cleaning, which is costly. Automatic cleaning is difficult, and failure to clean promptly affects airflow efficiency, impacting the control cabinet's operation. Multiple fans covering a large area are also necessary, consuming significant energy and potentially missing overheated areas, further reducing the control cabinet's lifespan. Additionally, most cooling devices require manual start / stop or continuous operation, resulting in high costs, poor energy efficiency, and potentially extended lifespan due to delayed cooling.

[0006] Preferably, the rainproof device further includes a rain collection box, which has a trapezoidal shell structure and overflow holes provided on two inclined sliding surfaces of the trapezoidal shell. Both sides of the rain collection box penetrate the top box and are fixedly connected to the top box. A diversion pipe is connected to the outlet of a water pump at its top, and the inlet of the water pump is connected to the bottom of the rainwater collection tank. A water delivery pipe is symmetrically connected to the bottom of the diversion pipe, and the end of the water delivery pipe away from the diversion pipe passes through the bottom of the inner wall of the top box and the top of the cabinet and is connected to the cooling mechanism. The return pipe connects to the bottom of the rain collection box at its top. Two sets of return pipes are symmetrically distributed at the bottom of the rain collection box. The end of the return pipe away from the rain collection box passes through the bottom of the inner wall of the top box and the top of the cabinet and connects to the cooling mechanism. Rainwater is filtered and collected through the overflow hole of the rain collection box. After it is full, it is discharged through the inclined surface and water guide groove to avoid water accumulation and corrosion of the parts. The photovoltaic panel absorbs solar energy to achieve energy saving. The U-shaped ventilation channel is equipped with a rainproof plate and a dustproof net to prevent rainwater and dust from entering while exhausting hot air from the cabinet, thus taking into account rainproof, dustproof, ventilation and energy saving.

[0007] Preferably, the linkage component includes a linkage frame, a turntable is rotatably connected to one side of the linkage frame via a bracket, a drive shaft of a linkage motor is fixedly connected to the side of the turntable away from the linkage frame, and L-shaped connecting frames are symmetrically fixedly connected to the bottom of the linkage frame.

[0008] Preferably, the end of the L-shaped connecting frame away from the linkage frame is fixedly connected to the air handling component, one side of the linkage frame is fixedly connected to the cooling mechanism, and the linkage motor is fixedly connected to one side of the inner wall of the cabinet.

A first sliding groove is provided on the side of the dust filter plate. An inclined brush rod is slidably connected to the inner wall of the first sliding groove via a slider. Multiple sets of inclined brush rods are provided and evenly distributed on one side of the dust filter plate. The multiple sets of inclined brush rods are fixedly connected by a fixing rod, and a connecting plate is fixedly connected to the bottom of the fixing rod.

[0010] Preferably, a desiccant is filled between the air filter plate and the dust filter plate. A sliding rod is symmetrically connected to the bottom of the inner wall of the air handling unit between the air filter plate and the dust filter plate. A stirring frame is fixedly connected to the top of the sliding rod. Stirring plates are evenly rotated and connected to both sides of the stirring frame. The bottom of the sliding rod is fixedly connected to a connecting plate. One side of the connecting plate is fixedly connected to one end of an L-shaped connecting frame. The air handling unit is fixedly connected to one side of the heat dissipation box and communicates with the opening of the heat dissipation box. The fan draws in outside air, which is filtered by the dust filter plate and dehumidified by the desiccant before being sent into the cabinet for cooling. The linkage motor drives the brush rod to clean the dust filter plate back and forth to avoid clogging. At the same time, it drives the stirring frame to turn the desiccant to prevent local moisture saturation and ensure that the air entering the cabinet is dry and dust-free, thereby improving the cooling effect.

[0011] Preferably, the cooling mechanism includes an annular square tube, with connecting square tubes uniformly fixedly connected to the inner side of the annular square tube. A heat-conducting plate is uniformly and fixedly connected between adjacent sets of connecting square tubes, annular square tubes and connecting square tubes. The heat-conducting plate has a W-shaped plate structure. A fixing frame is symmetrically fixedly connected to one side of the annular square tube. A rotating shaft is uniformly and rotatably connected to the inner wall of the fixing frame. A guide plate is sleeved and fixedly connected to the part of the rotating shaft located between the two sets of fixing frames.

[0012] Preferably, a second sliding groove is provided on one side of the fixed frame, and a toothed rod is slidably connected to the inner wall of the second sliding groove via a slider. A toothed ring is sleeved and fixedly connected on the rotating shaft, and the side of the toothed ring meshes with the toothed rod. Two sets of annular square tubes are provided and symmetrically fixedly connected to the bottom of the inner wall of the cabinet. The top of the annular square tube is connected to the water supply pipe, and the bottom side of the annular square tube is connected to the return pipe. One side of the toothed rod is fixedly connected to the side of the linkage frame. The water pump pumps the collected rainwater into the annular square tube and the connecting square tube, forming a circulating cooling path with the refrigeration components. The W-shaped heat conduction plate efficiently transfers the heat of the cabinet. The linkage frame drives the toothed rod and the toothed ring to rotate, causing the guide plate to swing back and forth, evenly dispersing the cooled air to all parts of the cabinet to ensure uniform cooling.

[0013] Preferably, the opening and closing assembly includes a fixed box with heat transfer ports evenly distributed on its side. A self-resetting switch is fixedly connected to one side of the inner wall of the fixed box. Thermal expansion members are slidably connected to both sides of the inner wall of the fixed box. A sliding plate is fixedly connected to one side of each thermal expansion member. A connecting slide rod is symmetrically fixedly connected to one side of each sliding plate. The end of the connecting slide rod away from the sliding plate passes through the fixed box and is fixedly connected to an opening and closing plate. The opening and closing plate has evenly distributed communication openings on its side. The fixed box is fixedly connected to the inner wall of the cabinet. The side of the opening and closing plate is slidably connected to the inner wall of the guide groove via a slider. When the temperature inside the cabinet rises, the thermal expansion members expand, pushing the sliding plate to move, allowing the opening and closing plate to connect with the air inlet mesh and triggering the self-resetting switch to start the heat dissipation device. When the temperature drops, the thermal expansion members contract, the device automatically stops, and the opening and closing plate blocks the air inlet mesh, realizing on-demand start and stop, saving energy.

[0014] The beneficial effects of the technical solution provided by this invention include: 1. This energy-saving and heat-dissipating smart grid electrical control cabinet is equipped with a rainproof device and has multiple functions including rainwater collection and diversion, photovoltaic power generation, and ventilation protection. This improves the energy efficiency and durability of the control cabinet. The rainwater collection box can collect rainwater for cooling and orderly overflow discharge, preventing water accumulation on the top from corroding the components. At the same time, the photovoltaic panels absorb solar energy to provide self-powered electricity, achieving energy saving and consumption reduction. The U-shaped channel combined with the rainproof plate structure ensures the smooth discharge of hot air inside the cabinet while preventing rainwater from seeping in. The dustproof net effectively blocks the entry of external dust, achieving ventilation and heat dissipation, rain and dust protection, and energy saving, thus extending the overall service life of the control cabinet.

[0015] 2. This energy-saving and heat-dissipating smart grid electrical control cabinet, through the coordinated operation of linkage components and air handling components, continuously ensures that the air entering the cabinet is clean and dry, enabling the electrical components inside the control cabinet to operate stably. Outside air is filtered by dust plates and dehumidified by desiccant, preventing damp and dusty air from damaging components. The linkage structure drives the brush rod to automatically clean the dust plates, preventing filter screen blockage from affecting air intake. At the same time, the stirring rack repeatedly turns the desiccant to avoid local moisture absorption saturation, increase the air contact area, and make moisture absorption more uniform and efficient, always maintaining dust-free and dry air intake, reducing the probability of electrical component failure, and ensuring the long-term reliable operation of the control cabinet.

[0016] 3. This energy-saving and heat-dissipating smart grid electrical control cabinet is equipped with a cooling mechanism that utilizes collected rainwater to form a circulating water-cooling loop. Combined with a heat-conducting structure and oscillating airflow guide, water cooling and air cooling are integrated to significantly improve the overall heat dissipation and cooling efficiency of the cabinet. Rainwater circulates through pipes to carry away heat from the heat-conducting plates. The W-shaped heat-conducting plates increase the air heat exchange contact area, enabling more effective absorption of the cold temperature transferred by the heat-conducting plates and improving cooling efficiency. The linkage structure drives the airflow guide plate to oscillate back and forth, evenly distributing cold air throughout the cabinet and avoiding excessive local temperature differences. Furthermore, the use of collected rainwater for water cooling effectively improves energy efficiency and extends the overall service life of the control cabinet.

[0017] 4. This energy-saving and heat-dissipating smart grid electrical control cabinet is equipped with an opening and closing component. Relying on thermal expansion sensing, it realizes automatic start and stop of the heat dissipation system, intelligent temperature control operation, and effectively saves energy consumption. When the temperature inside the cabinet rises, the deformation of the thermal expansion component triggers the switch, automatically starting the fan and heat dissipation mechanism. At the same time, the opening and closing plate is aligned to conduct the air intake channel for heat dissipation. After the temperature drops, it automatically resets and stops, and closes the air intake screen. No manual operation is required to start and stop it. It works on demand to avoid continuous power consumption of the equipment under no-load. While accurately controlling the temperature, it reduces energy consumption and further improves the energy-saving performance and long-term stable operation of the smart grid electrical control cabinet.

[0020] For the first embodiment, please refer to... Figures 1-5 This invention provides an energy-saving and heat-dissipating smart grid electrical control cabinet. By incorporating a rainproof device 2, rainwater falls onto a rain collection box 28 on the inclined side of the top box 21 during rainy weather. The rainwater then flows into the rain collection box 28 through an overflow hole 29 for storage. The overflow hole 29 not only filters and allows rainwater to enter, but also allows excess rainwater to flow out along the inclined surface of the rain collection box 28 when it is full, ultimately entering a water guide trough 22 and being discharged from the inclined baffle 24 at the side edge of the top box 21. Simultaneously, photovoltaic panels 23 installed on the inclined side absorb solar energy to generate electricity, powering the internal electrical components of the device, thus improving efficiency. This design achieves energy-saving effects, and the water guide trough 22 further prevents water accumulation at the bottom of the photovoltaic panel 23, extending the service life of the photovoltaic panel 23. This allows for the collection of rainwater for cooling while preventing rainwater from accumulating on the top of the top box 21, which could lead to component corrosion and damage, thus extending the service life of the device. At the same time, hot air inside the cabinet 1 can be discharged from the cabinet 1 through the U-shaped channel 26, and the dustproof net 27 can prevent external dust from entering the cabinet 1 and causing damage to internal components. In addition, the rainproof plate 25 and the U-shaped channel 26 themselves work together to prevent rainwater from entering the U-shaped channel 26, ensuring ventilation and heat dissipation while improving rainproof and dustproof performance.

[0021] For the second embodiment, please refer to... Figures 1-7By using the linkage component 5 and the air handling component 8 in conjunction, when cooling the inside of the cabinet 1, the fan 11 is first started to draw in outside air through the dust filter 27. After most of the dust is filtered out by the dust filter plate 83, the air is further dehydrated by a desiccant to prevent the damp and dusty air from damaging the electrical components inside the cabinet 1 and to extend the service life of the electrical components. Then, the air is sent into the cabinet 1 through the air inlet 6, and finally cooled by the cooling mechanism 4 to cool the cabinet 1. When the linkage motor 53 is working, its drive shaft rotates, which drives the turntable 52 to rotate. The rotation of the turntable 52 drives the linkage frame 51 to move up and down repeatedly. When the linkage frame 51 moves up and down repeatedly, it drives the L-shaped connecting frame 54 to move up and down simultaneously. The L-shaped connecting frame 54 drives the connecting plate 87 to move up and down repeatedly. As the connecting plate 87 moves downward, the inclined brush rod 85 drives the dust filter plate 83 to reciprocate along the first sliding groove 84. The dust brushed off slides down through the inclined structure of the inclined brush rod 85, preventing dust from clogging the dust filter plate 83 and affecting the air intake effect. At the same time, the connecting plate 87 drives the sliding rod 88 to move up and down reciprocally. The sliding rod 88 drives the stirring frame 89 to move reciprocally inside the desiccant. The stirring plate 810 on the stirring frame 89 rotates due to the resistance of the desiccant during the movement, stirring the desiccant. This prevents the desiccant from becoming locally saturated due to long-term static storage, which reduces the overall moisture absorption effect. It also increases the contact area between the desiccant and the humid air, making the moisture absorption more uniform and improving the air treatment effect. This ensures that the air entering the cabinet 1 is dry and dust-free, further improving the cooling effect inside the cabinet 1.

[0022] Third embodiment, please refer to Figures 1-9By incorporating a cooling mechanism 4, rainwater is stored and then pumped into a distribution pipe 210 via a water pump 211. The distribution pipe 210 then delivers the rainwater through a water pipe 212 into the annular square pipe 41 and the connecting square pipe 42. A cooling component is installed on the annular square pipe 41. The rainwater flows within the annular square pipe 41 and the connecting square pipe 42, eventually returning to the rainwater collection box 28 via a return pipe 213, forming a circulating cooling path. The heat-conducting plate 43 absorbs heat from the air inside the cabinet 1 and quickly transfers this heat to the rainwater inside the annular square pipe 41 and the connecting square pipe 42. The heat is then carried away through water circulation. The W-shaped heat-conducting plate 43 increases the contact area with the air inside the cabinet 1, thereby improving the air cooling efficiency and further enhancing the cooling effect. The speed allows the air treated by the air handling unit 8 to be effectively cooled. At the same time, when the linkage frame 51 moves up and down, it drives the rack 48 to move up and down synchronously along the second slide groove 47. The rack 48 drives the gear ring 49 to rotate back and forth through meshing. The gear ring 49 drives the rotating shaft 45 to rotate back and forth. The rotating shaft 45 drives the guide plate 46 to swing back and forth, adjusting the angle of the guide plate 46 to guide the cooled air. This allows the cold air to be evenly distributed in all positions inside the cabinet 1, increasing the coverage of the cold air entering the cabinet 1 and avoiding local temperatures that are too low or too high. This makes the overall cooling inside the cabinet 1 more uniform and further improves the heat dissipation and cooling effect inside the cabinet 1.

[0023] For the fourth embodiment, please refer to [link / reference]. Figures 1-11 By incorporating the opening and closing component 9, when the internal temperature of the cabinet 1 rises, heat enters the fixed box 91 through the heat transfer port 92. The thermal expansion component 94 expands due to heat, pushing the sliding plate 95 towards the self-reset switch 93. The sliding plate 95 slides, causing the connecting rod 96 to slide, which in turn moves the opening and closing plate 97, aligning the connecting port 98 on the opening and closing plate 97 with the mesh of the air inlet screen 6 on the side wall of the cabinet 1. Simultaneously, the sliding plate 95 slides to the contact point with the self-reset switch 93, triggering the self-reset switch 93 to control the fan 11 and the linkage motor 53 to start. At this time, the device begins to work to dissipate heat. When the internal temperature of the cabinet 1 decreases, the thermal expansion component 94 contracts, pulling the sliding plate 95 back to its original position. The sliding plate 95 moves away from the self-reset switch 93, and the device automatically stops working. The opening and closing plate 97 returns to its original position, blocking the air inlet screen 6. Thus, the heat dissipation device can automatically start and stop according to the internal temperature of the cabinet 1, avoiding continuous operation and wasting energy, and further improving the energy-saving effect.

[0024] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
