Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and in particular to a partitioned protective power distribution cabinet assembly. Background Technology

[0002] Distribution cabinets, as crucial equipment in power systems for receiving, distributing, and controlling electrical energy, are widely used in industrial, commercial, and building power distribution systems. They typically integrate electrical components such as circuit breakers, relays, switches, terminals, and cables, undertaking the critical task of power transmission and distribution. However, during operation, distribution cabinets may experience localized overheating or even electric arcing due to electrical short circuits, overloads, poor contact, equipment aging, or the intrusion of external dust and moisture, potentially leading to fire accidents.

[0003] Currently, in order to save space and improve site utilization, multiple distribution cabinets are usually arranged in a row during installation and layout. The distance between adjacent distribution cabinets is small, or they are even installed closely side by side. Although this arrangement is conducive to efficient use of space, it poses a significant safety hazard. When one distribution cabinet catches fire due to a malfunction, the flames and high-temperature airflow can easily spread rapidly to adjacent distribution cabinets through air conduction, heat radiation, or flying sparks, forming a chain reaction of fire, causing the fire to expand, increasing the difficulty of firefighting and the extent of damage. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose an interval protection type distribution cabinet group to solve the problem that in the current installation and layout of distribution cabinets, in order to save space and improve site utilization, multiple distribution cabinets are usually arranged in a row with small spacing between adjacent distribution cabinets, or even directly installed closely side by side. When one distribution cabinet fails and catches fire, it is easy to spread to adjacent distribution cabinets, forming a chain fire.

[0009] Furthermore, traction sprockets are provided at both ends of the horizontal suspension rail, and traction chains are connected to the outer side of the traction sprockets. The translational protective frame is connected to the traction chains, and a traction motor is provided in the middle of the traction sprockets.

[0010] Furthermore, a heat-insulating connecting frame is provided on the rear side of the power distribution cabinet, and an extended rear plate is connected to the rear side of the heat-insulating connecting frame. The extended rear plate is arranged parallel to the back panel of the power distribution cabinet. The left, right, and top edges of the extended rear plate extend beyond the left, right, and top edges of the back panel of the power distribution cabinet, respectively. A protective gap is provided between the extended rear plate and the back panel of the power distribution cabinet through the heat-insulating connecting frame.

[0011] Furthermore, the extended rear plate is provided with fitting sealing grooves on the left and right sides and the top.

[0013] The beneficial effects of this invention are as follows: As can be seen from the above description, the spaced protective distribution cabinet group provided by this invention allows multiple distribution cabinets to be horizontally arranged and installed along a sliding track. When a fire occurs, a temperature sensor detects the fire, and the sliding adjuster moves to the area directly below the distribution cabinets on the left and right sides of the fire-affected cabinet. Then, a sliding adjustable connecting block is embedded in the fitting adjustment groove of the supporting base of the corresponding distribution cabinet, so as to drive the corresponding distribution cabinet to move away from the fire-affected cabinet. This creates a space on the left and right sides of the fire-affected distribution cabinet, forming a necessary physical isolation zone and effectively preventing the spread of fire. In addition, since the distribution cabinets are kept at a small distance to save space under normal circumstances, and the distance is widened only in emergencies, this method not only ensures the space efficiency of daily use, but also enhances the ability to respond to sudden fire events. This not only improves the self-protection capability of the power distribution system in the face of fire, but also reduces the risk of large-scale power outages caused by fire, ensuring the safety of personnel and equipment.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a type of partitioned protective distribution cabinet assembly includes a sliding rail 1, above which multiple distribution cabinets 4 are horizontally arranged, and further includes: The support base 6 is located at the bottom of the power distribution cabinet 4. The power distribution cabinet 4 is slidably connected to the translation rail 1 through the support base 6. The bottom of the support base 6 is provided with a support guide wheel 601. The support base 6 is slidably connected to the translation rail 1 through the support guide wheel 601. A temperature sensor 407 is installed inside the power distribution cabinet 4. The translation adjuster 2 is located in the middle of the translation track 1. The inner side of the translation track 1 is provided with a moving guide groove 101. A translation rack 102 is provided in the middle of the moving guide groove 101. The front and rear sides of the translation adjuster 2 are symmetrically provided with engagement guide seats 201. A translation gear 202 is provided in the middle of the engagement guide seat 201. A translation motor 203 is connected in the middle of the translation gear 202. The translation gear 202 and the translation rack 102 mesh with each other. A connecting guide sleeve 302 is vertically positioned in the middle of the translation adjuster 2. A connecting block 303 is slidably fitted inside the connecting guide sleeve 302. A connecting spring 304 is located at the bottom of the connecting block 303, and a reset electromagnet 305 is located below the connecting block 303. A fitting adjustment groove 602 is located in the middle of the bottom surface of the support base 6. The fitting adjustment groove 602 and the connecting block 303 are fitted together. Multiple distribution cabinets 4 can be horizontally arranged and installed along the translation track 1. The total length of the translation track 1 is greater than the sum of the overall widths of all the distribution cabinets 4 it supports, so as to reserve the track length for the width of one or two distribution cabinets 4. During normal use, the distance between the distribution cabinets 4 is small to save space, and the reserved space is used as a passage. When a fire occurs, after the temperature sensor 407 detects the fire, the translation adjuster 2 moves to the bottom of the distribution cabinets 4 on the left and right sides of the corresponding fire distribution cabinet 4. Then, the sliding adjustable connecting block 303 is embedded in the fitting adjustment groove 602 of the supporting base 6 of the corresponding distribution cabinet 4, so as to drive the corresponding distribution cabinet 4 to move away from the fire cabinet, thereby leaving a gap space on the left and right sides of the fire distribution cabinet 4 to prevent the fire from spreading.

[0020] In this embodiment, the power distribution cabinet group improves fire safety by dynamically adjusting the spacing between the power distribution cabinets. The power distribution cabinet group includes key components such as a sliding track 1, multiple power distribution cabinets 4, a support base 6, a sliding adjuster 2, and a connecting guide sleeve 302. The power distribution cabinets 4 are arranged horizontally above the sliding track 1. Each power distribution cabinet 4 has a support base 6 at its bottom, and is slidably connected to the sliding track 1 through a support guide wheel 601 at its bottom. To monitor temperature changes, a temperature sensor 407 is installed inside the power distribution cabinet 4. Cabinet 4 can be horizontally installed along sliding rail 1, and the total length of sliding rail 1 is greater than the sum of the overall widths of all the distribution cabinets 4 it supports, so as to reserve the track length for the width of one or two distribution cabinets 4. During normal use, the spacing between distribution cabinets 4 is small to save space, and the reserved space is used as a passageway. In the event of a fire, after the temperature sensor 407 detects the fire, the sliding adjuster 2 moves to directly below the distribution cabinets 4 on the left and right sides corresponding to the burning distribution cabinet 4, and then... The connecting block 303 of the section is embedded in the fitting adjustment groove 602 of the supporting base 6 of the corresponding distribution cabinet 4, so as to drive the corresponding distribution cabinet 4 to move away from the fire cabinet. This drives the distribution cabinet 4 to move along the translation track 1 away from the fire point, thereby forming an isolation space around the fire distribution cabinet to prevent the fire from spreading. By setting temperature sensors 407 to monitor the internal temperature changes of each distribution cabinet in real time, potential fire risks can be detected and responded to in a timely manner. The translation adjuster 2 combined with the sliding connecting block 303 mechanism can quickly adjust the position of adjacent distribution cabinets after a fire is detected, creating the necessary physical isolation zone and effectively preventing the fire from spreading. In addition, since the distribution cabinets are kept at a small distance to save space under normal circumstances, and the distance is widened only in emergencies, this method not only ensures the space efficiency of daily use, but also enhances the ability to respond to sudden fire events. This not only improves the self-protection capability of the power distribution system in the face of fire, but also reduces the risk of large-scale power outages caused by fire, and ensures the safety of personnel and equipment.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, preferably, the power distribution cabinet group has heat dissipation grilles 404 on the left and right side walls and the middle of the rear back panel 403 of the power distribution cabinet body 4, which are used to realize air convection and improve the heat dissipation efficiency inside the cabinet. At the same time, an air outlet 405 is provided in the center of the top of the power distribution cabinet body 4, and a cooling fan 406 is installed inside the air outlet 405 to actively exhaust the heat generated inside the power distribution cabinet due to the operation of electrical components to the external environment, thereby effectively controlling the temperature inside the cabinet and preventing electrical faults or fire risks caused by overheating.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, preferably, horizontal guide rods 204 are symmetrically arranged on the left and right sides of the translation adjuster 2 of the power distribution cabinet group. The horizontal guide rods 204 are connected by a translation pusher 3. A guide sleeve 301 is provided in the middle of the translation pusher 3. The guide sleeve 301 slides with the horizontal guide rod 204, so that the translation pusher 3 can slide smoothly along the horizontal guide rod 204. A connecting guide sleeve 302 is vertically arranged above the translation pusher 3 to realize the connection and driving action between the translation pusher 3 and the support base 6 of the power distribution cabinet 4. An electric telescopic rod 205 is also arranged parallel to the outside of the horizontal guide rod 204. The fixed end of the electric telescopic rod 205 is connected to the translation adjuster 2, and its telescopic end is connected to the translation pusher 3. This constitutes an actuator that can synchronously drive the left and right distribution cabinets 4 to move. When the temperature sensor 407 detects an abnormal increase in temperature inside a distribution cabinet 4 and determines that a fire has occurred, the control system will activate the electric telescopic rod 205. Through the telescopic action, the left and right sliding pushers 3 will be pushed outward, causing the connecting guide sleeve 302 to connect with the support base 6 of the adjacent distribution cabinet 4. This drives these distribution cabinets 4 to move along the sliding track 1 in a direction away from the fire point, so that the sliding adjuster 2 can quickly and synchronously push the cabinets on the left and right sides of the burning distribution cabinet 4 to form a sufficient isolation space to prevent the fire from spreading and improve the fire safety performance of the overall power distribution system.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, preferably, a horizontal hanging rail 7 is provided on the upper front side of the distribution cabinet 4. This horizontal hanging rail 7 is arranged parallel to the lower translational rail 1 and is used to support and guide the movement of the translational protective frame 8. The translational protective frame 8 is mounted on the horizontal hanging rail 7 via a sliding connection and can move along the hanging rail direction under the drive of the traction mechanism. Traction sprockets 701 are respectively provided at the left and right ends of the horizontal hanging rail 7. Traction chains 702 are sleeved on the traction sprockets 701. The translational protective frame 8 is fixedly connected to the traction chains 702. The traction sprockets 701 are driven to rotate by the traction motor 703, thereby driving the traction chains 702 to move and realize the left and right movement control of the translational protective frame 8. A sliding guide rail 801 is provided at the bottom of the translational protective frame 8. This sliding guide rail 801 is arranged perpendicular to the translational rail 1 and is used to guide the lateral movement of the enclosed protective shell 9. The enclosed protective shell 9 is moved by the sliding guide rail 701. The connection method is set below the sliding guide rail 801 and matches the shape of the distribution cabinet 4. It can completely cover the front and side walls of the distribution cabinet 4. The enclosed protective shell 9 is made of fireproof and heat-insulating materials, such as ceramic fiber board, aluminum silicate heat insulation board or composite fireproof steel plate, which has good heat insulation and flame retardant properties. The enclosed protective shell 9 is connected to the translational protective frame 8 by a pneumatic telescopic rod 802. The fixed end of the pneumatic telescopic rod 802 is installed on the translational protective frame 8, and the telescopic end is connected to the enclosed protective shell 9. When a fire occurs in a distribution cabinet 4, the system identifies the fire location through the temperature sensor 407. First, the translational adjuster 2 pushes the adjacent distribution cabinet 4 apart to form an isolation space. Subsequently, the traction motor 703 starts, driving the traction sprocket 701 to rotate, which moves the translational protective frame 8 to directly above the burning power distribution cabinet 4. Then, the pneumatic telescopic rod 802 pushes the enclosed protective shell 9 to slide along the sliding guide rail 801 to the front of the burning power distribution cabinet 4, and further slides and nests to its outside, forming a physical isolation and thermal protection barrier, thereby effectively blocking the spread of fire and improving the overall fire safety performance of the system. On the basis of achieving physical isolation between the power distribution cabinets 4, the enclosed protective shell 9 is further introduced to externally cover the burning cabinet, forming a double protection mechanism, effectively curbing the spread of fire and improving the overall fire protection performance.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, preferably, a heat insulation connection frame 501 is provided on the rear side of the power distribution cabinet 4. The heat insulation connection frame 501 is made of a material with good heat insulation performance, such as ceramic fiber heat insulation board, aerogel heat insulation board, or composite high temperature resistant non-metallic material, etc., to achieve thermal isolation between the power distribution cabinet 4 and the rear structure. One end of the heat insulation connection frame 501 is fixedly connected to the back plate 403 of the power distribution cabinet 4, and the other end is connected to an extension rear plate 5. The extension rear plate 5 is arranged parallel to the back plate 403 of the power distribution cabinet 4. Its left side edge, right side edge and top edge extend outward, exceeding the corresponding edge of the back plate 403 of the power distribution cabinet 4, forming a larger protective area. A certain protective gap 502 is formed between the extension rear plate 5 and the back plate 403 of the power distribution cabinet 4 through the heat insulation connection frame 501. This gap can effectively block heat from being transferred to the rear structure through heat conduction, heat radiation, etc. At the same time, this gap also provides a certain auxiliary channel for heat dissipation inside the power distribution cabinet 4, which is conducive to improving the overall heat dissipation performance.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, preferably, the left and right sides and the top edge of the extended rear plate 5 are provided with fitting sealing grooves 503. The fitting sealing grooves 503 extend along the edge of the extended rear plate 5 and are used to form a sealing fit with the corresponding structure of the closed protective shell 9. The closed protective shell 9 is composed of a protective front plate 901, protective side plates 902 symmetrically arranged on the left and right sides of the protective front plate 901, and a protective top plate 903 connecting the top of the protective front plate 901 and the protective side plates 902. The whole is U-shaped and can be slidably fitted from front to back onto the fire distribution system. On the exterior of the cabinet 4, the rear edges of the protective side panel 902 and the protective top panel 903 are provided with snap-fit ​​edges that match the fitting sealing groove 503. When the enclosed protective shell 9 slides to the outside of the distribution cabinet 4, the snap-fit ​​edges of the protective side panel 902 and the protective top panel 903 can be embedded into the fitting sealing groove 503 on the extended rear panel 5, achieving a tight fit and forming a closed space. In addition, the top left and right sides of the support base 6 are symmetrically provided with fitting connection grooves 603 for connecting with the bottom edge of the protective side panel 902 of the enclosed protective shell 9, so that the protective... The protective shell can also achieve positioning and sealing at the bottom. In the event of a fire, after the translation adjuster 2 pushes open the distribution cabinets 4 on both sides of the burning distribution cabinet 4, the translation protective frame 8 drives the closed protective shell 9 to move to the front of the burning distribution cabinet 4, and pushes it along the sliding guide rail 801 through the pneumatic telescopic rod 802, so that the protective shell slides and snaps onto the outside of the burning distribution cabinet 4 from the front. At this time, the protective front plate 901 is attached to the front side of the distribution cabinet 4, and the protective side plate 902 and the protective top plate 903 are respectively embedded in the fitting and sealing groove 50 of the extended rear plate 5. In section 3, the bottom of the protective side plate 902 is embedded in the fitting connection groove 603 of the supporting base 6, thereby completely enclosing the burning power distribution cabinet 4 inside the protective shell, forming a physically isolated, heat-insulated, and sealed protective space, effectively preventing the spread of flames, high-temperature gases, and smoke. Thus, through the multi-point fitting and sealing structure between the protective shell and the power distribution cabinet 4, the burning power distribution cabinet 4 can be quickly and completely sealed in the event of a fire, forming a physically isolated space, effectively preventing the spread of fire, effectively preventing the leakage of smoke and high-temperature gases, and reducing the risk of secondary injury.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, preferably, the protective front panel 901 of the enclosed protective shell 9 is provided with multiple horizontal delivery pipes 904 in the middle. The horizontal delivery pipes 904 are evenly arranged laterally along the protective front panel 901 and are used to deliver fire extinguishing agent into the power distribution cabinet 4. Correspondingly, the front door 401 of the power distribution cabinet 4 is provided with multiple heat dissipation openings 402 in the middle. The positions of the heat dissipation openings 402 correspond one-to-one with the horizontal delivery pipes 904, so that when the enclosed protective shell 9 slides and snaps to the outside of the power distribution cabinet 4, the horizontal delivery pipes 904 can be accurately inserted into the power distribution cabinet 4. Multiple spray holes 905 are evenly distributed on the pipe body of the horizontal delivery pipes 904, which are used to evenly spray the fire extinguishing agent in the form of mist or fine stream into various areas inside the power distribution cabinet 4. The outer end of the horizontal delivery pipe 904 is connected to the pressurized storage tank 803 via the delivery pipe 804. The pressurized storage tank 803 stores an inert gas-driven extinguishing agent, such as heptafluoropropane, fine water mist, or dry powder extinguishing agent. It is also connected to the horizontal delivery pipes 904 on all the distribution cabinets 4 via the delivery pipe 804. An electromagnetic switch valve 805 is installed in the middle of the delivery pipe 804 to control the release timing of the extinguishing agent. In the event of a fire, after the protective enclosure 9 completes the sealing action on the distribution cabinet 4, the control system automatically triggers the electromagnetic switch valve 805 to open. The extinguishing agent in the pressurized storage tank 803 is then propelled by the high-pressure gas through the delivery pipe. The extinguishing agent 804 enters the horizontal delivery pipe 904 and is evenly sprayed into the distribution cabinet 4 through the spray opening 905, quickly extinguishing the fire source and suppressing the reignition of the fire. By integrating the horizontal delivery pipe 904 and the spray opening 905 structure within the enclosed protective shell 9, the fire extinguishing system and the fireproof isolation structure are organically combined. The fire extinguishing procedure can be activated immediately after the enclosed protective shell 9 is closed, with rapid response and high efficiency. The horizontal delivery pipe 904 and the heat dissipation opening 402 correspond one-to-one, ensuring that the extinguishing agent can accurately enter the interior of the distribution cabinet 4. Combined with the evenly distributed spray openings 905, comprehensive coverage of all areas inside the cabinet is achieved, improving the fire extinguishing effect.

[0027] The spaced-protection distribution cabinet group provided by this invention consists of multiple distribution cabinets 4 that can be horizontally arranged and installed along a translation track 1. When a fire occurs, the temperature sensor 407 detects the fire, and the translation adjuster 2 moves to the side directly below the distribution cabinets 4 on the left and right sides of the fire. Then, the sliding adjustable connecting block 303 is embedded in the fitting adjustment groove 602 of the support base 6 of the corresponding distribution cabinet 4, so as to drive the corresponding distribution cabinet 4 to move away from the fire cabinet. This leaves a space on the left and right sides of the fire distribution cabinet 4, creating a necessary physical isolation zone and effectively preventing the spread of fire. In addition, since the distribution cabinets are kept at a small distance to save space under normal circumstances, and the distance is widened only in emergencies, this method not only ensures the space efficiency of daily use, but also enhances the ability to respond to sudden fire events. It not only improves the self-protection capability of the power distribution system in the face of fire, but also reduces the risk of large-scale power outages caused by fire, and protects the safety of personnel and equipment.
