Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and in particular to a flood-proof outdoor power distribution cabinet. Background Technology

[0002] As an important device in the power system for distributing, controlling and protecting electrical equipment, distribution cabinets are widely used in urban power grids, industrial plants, commercial buildings and public facilities. Outdoor distribution cabinets are usually installed in open or semi-enclosed environments and need to have good protection performance to cope with various complex weather conditions. In order to ensure their normal operation, the structural design of distribution cabinets not only requires a certain mechanical strength and protection level, but also needs to consider the heat dissipation requirements of electrical equipment during operation. The cabinet is usually equipped with heat dissipation holes or ventilation structures to enhance air circulation and prevent the internal temperature from being too high, which would affect the stability and lifespan of electrical components.

[0003] In extreme weather or natural disasters, such as floods, outdoor distribution cabinets are highly susceptible to water damage. Because the cabinets have ventilation holes, floodwater or water can easily enter the cabinets through these openings, causing short circuits in electrical equipment, reduced insulation performance, and even equipment damage or system failure. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a flood-proof outdoor power distribution cabinet to solve the problem that when floods occur, floodwater or water can easily enter the cabinet through these openings, causing short circuits in electrical equipment and resulting in equipment damage.

[0005] To achieve the above objectives, the present invention provides a flood-proof outdoor power distribution cabinet, comprising a cabinet body, wherein the cabinet body is provided with an electrical mounting bracket for assembling electrical equipment, and further comprising: Horizontal ventilation slots are provided, with multiple horizontal ventilation slots evenly and parallelly arranged in the middle of the left and right side panels of the cabinet along the vertical direction of the side panels. The horizontal ventilation slots penetrate the side panels of the cabinet and are used for ventilation and heat dissipation of electrical equipment installed in the cabinet. Horizontal guide sleeves are symmetrically arranged on the left and right sides of the horizontal ventilation slots. A waterproof sealing plate is arranged parallel to the outside of the horizontal ventilation slot.

Multiple drive sliders are evenly connected in the middle of the linkage adjustment frame. The drive sliders are provided with drive inclined surfaces on their sides. The drive inclined surfaces and the linkage inclined surfaces are fitted together. When the linkage adjustment frame drives the drive sliders to slide downward, the drive sliders slide inward by pressing against the inner linkage sliders through the drive inclined surfaces and the linkage inclined surfaces. Then, the horizontal connecting rod pulls the waterproof sealing plate close to and seals the horizontal ventilation groove.

[0006] Furthermore, an adjusting sleeve is provided on the outer side of the linkage adjusting frame, an adjusting screw is nested in the middle of the adjusting sleeve, and an adjusting motor is connected to the shaft end of the adjusting screw.

[0007] Furthermore, a fitting sealing ring is provided around the outer edge of the horizontal ventilation slot, and a fitting sealing groove is provided around the inner side of the waterproof sealing plate, with the fitting sealing groove and the fitting sealing ring being sized to fit each other.

[0008] Furthermore, a fixed guide rod is vertically arranged on the outer side of the bottom of the side panel of the cabinet, and a detection float is arranged on the outer side of the fixed guide rod. A connecting sleeve is arranged in the middle of the detection float, and the detection float is slidably connected to the fixed guide rod through the connecting sleeve. A Hall sensor is arranged on the top of the fixed guide rod, and a detection magnet is arranged on the bottom of the detection float.

[0009] Furthermore, the detection float has a top-pressure inclined surface on the side near the waterproof sealing plate, and the waterproof sealing plate has an external linkage slider on the side near the detection float. The side of the external linkage slider has a guide inclined surface, and the guide inclined surface and the top-pressure inclined surface are in contact with each other.

[0010] Furthermore, a horizontal connecting pipe is provided below the horizontal ventilation slot, the outer end of the horizontal connecting pipe is provided with a connecting opening, the inner end of the horizontal connecting pipe is connected to a vertical connecting pipe, the top end of the vertical connecting pipe is lower than the horizontal ventilation slot, the top end of the vertical connecting pipe is provided with a balancing opening, and a central sliding sleeve is provided in the middle of the balancing opening.

[0011] Furthermore, a hollow floating plug is nested and slidably disposed inside the vertical connecting pipe, and a linkage rod is vertically disposed on the top of the hollow floating plug, and the linkage rod is nested and slidably disposed inside the central sliding sleeve.

[0012] Furthermore, a guide roller is provided in the middle of the inner side of the horizontal ventilation slot, and a connecting traction cable is connected to the top of the linkage rod. The other end of the connecting traction cable is guided and connected to the middle of the inner side of the waterproof sealing plate through the guide roller.

[0013] The beneficial effects of this invention are as follows: As can be seen from the above description, the flood-proof outdoor power distribution cabinet provided by this invention, through the linkage structure between the linkage adjustment frame, the drive slider and the internal linkage slider, can automatically trigger the waterproof sealing plate to close the ventilation slot before the water level rises and the cabinet is submerged, effectively preventing floodwater from entering the cabinet and protecting the electrical equipment. Under normal operating conditions, the ventilation slot remains open to ensure the heat dissipation needs of the electrical equipment inside the cabinet.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a flood-proof outdoor power distribution cabinet includes a cabinet body 1, and an electrical mounting bracket 101 for assembling electrical equipment is provided inside the cabinet body 1. It also includes: Horizontal ventilation slots 2, multiple horizontal ventilation slots 2 are evenly and parallelly arranged in the middle of the left and right side panels 102 of the cabinet 1 along the vertical direction of the side panel 102 of the cabinet 1. The horizontal ventilation slots 2 are arranged through the side panel 102 of the cabinet 1. The horizontal ventilation slots 2 are used for ventilation and heat dissipation of electrical equipment installed in the cabinet 1. Horizontal guide sleeves 202 are symmetrically arranged on the left and right sides of the horizontal ventilation slots 2. A waterproof sealing plate 3 is set parallel to the outside of the horizontal ventilation slot 2. Horizontal connecting rods 302 are symmetrically connected to the left and right sides of the waterproof sealing plate 3. The waterproof sealing plate 3 slides along the horizontal guide sleeve 202 through the horizontal connecting rods 302 to move away from the horizontal ventilation slot 2 or to close to it to close the horizontal ventilation slot 2. A return spring 303 is set in the middle of the horizontal connecting rod 302. An inner linkage slider 304 is connected to the inner end of the horizontal connecting rod 302, and a linkage inclined surface 305 is provided on the side of the inner linkage slider 304. The linkage adjustment frame 4 is vertically slidably installed inside the side panel 102 of the cabinet 1. Multiple drive sliders 401 are evenly connected in the middle of the linkage adjustment frame 4. The drive sliders 401 are provided with drive inclined surfaces 402 on their sides. The drive inclined surfaces 402 and the linkage inclined surfaces 305 are fitted together. When the linkage adjustment frame 4 drives the drive sliders 401 to slide downward, the drive sliders 401 press against the inner linkage sliders 304 and slide inward through the drive inclined surfaces 402 and the linkage inclined surfaces 305. Then, the horizontal connecting rod 302 pulls the waterproof sealing plate 3 closer to the sealed horizontal ventilation slot 2.

[0020] In this embodiment, the distribution cabinet is equipped with an electrical mounting bracket 101 inside the cabinet 1 for installing electrical equipment to ensure the stable installation and safe operation of electrical components. Multiple horizontal ventilation slots 2 are provided on the left and right side panels 102 of the cabinet 1. These horizontal ventilation slots 2 are evenly and parallelly arranged along the vertical direction of the side panels 102 of the cabinet 1 and penetrate through the side panels 102 of the cabinet 1 to achieve air circulation inside and outside the cabinet 1 and improve heat dissipation efficiency. A waterproof sealing plate 3 is provided on the outside of each horizontal ventilation slot 2 to automatically close the ventilation slot in emergency situations such as flooding, preventing water from entering the cabinet 1. 3. The horizontal connecting rods 302, symmetrically arranged on its left and right sides, are slidably connected to the horizontal guide sleeves 202 on the side panel 102 of the cabinet 1. The horizontal connecting rods 302 can slide horizontally within the guide sleeves, causing the waterproof sealing plate 3 to move away from or towards the ventilation slot, thereby realizing the opening and closing of the ventilation slot. A return spring 303 is provided in the middle of the horizontal connecting rods 302. Under normal conditions, it pushes the waterproof sealing plate 3 away from the outside of the ventilation slot to keep the closed ventilation slot open. An inner linkage slider 304 is connected to the inner end of the horizontal connecting rods 302. The inner linkage slider 304 is provided with a linkage inclined surface 305 on the inner side of the side panel 102 of the cabinet 1. A linkage adjustment frame 4 is provided, which can slide vertically. Multiple drive sliders 401 are connected to its center. Each drive slider 401 has a drive ramp 402 on its side, which engages with the linkage ramp 305 of the inner linkage slider 304. When the linkage adjustment frame 4 moves downwards, the drive sliders 401 slide down accordingly. Through the interaction between the drive ramp 402 and the linkage ramp 305, the inner linkage slider 304 is pushed inwards. The inner linkage slider 304, via the horizontal connecting rod 302, moves the waterproof sealing plate 3 inwards, ensuring it fits tightly against the cabinet body 1. Side panel 102 encloses the horizontal ventilation slot 2 to prevent floodwater from entering the cabinet 1. Through the linkage structure between the linkage adjustment frame 4, the drive slider 401 and the internal linkage slider 304, the waterproof sealing plate 3 can be automatically triggered to close the ventilation slot before the water level rises and the cabinet 1 is flooded, effectively preventing floodwater from entering the cabinet 1 and protecting the electrical equipment. Under normal operating conditions, the ventilation slot remains open to ensure the heat dissipation needs of the electrical equipment inside the cabinet 1. In the event of flooding, the waterproof sealing plate 3 can quickly respond and close the ventilation slot, achieving the dual functions of ventilation and waterproofing, and improving the environmental adaptability of the distribution cabinet.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, preferably, an adjusting sleeve 403 is fixedly installed on the outside of the linkage adjusting frame 4 of the distribution cabinet. The adjusting sleeve 403 has an internal thread in the middle, which matches and is threadedly connected to the adjusting screw 404. The adjusting screw 404 is arranged vertically. The adjusting motor 405 is fixedly installed on the side plate 102 of the cabinet 1 and can drive the adjusting screw 404 to rotate according to the control signal, thereby driving the linkage adjusting frame 4 to slide up and down vertically. When the adjusting motor 405 starts and drives the adjusting screw 404 to rotate, due to the threaded engagement between the adjusting screw 404 and the adjusting sleeve 403, the linkage adjusting frame 4 will move up and down along the vertical guide rail. The linkage adjusting frame 4 drives the multiple driving sliders 401 on it to slide synchronously. Through the driving inclined surface 402 on the driving slider 401 and the inner linkage slider... The interaction between the linkage inclined surfaces 305 of 304 pushes the inner linkage slider 304 to slide into the cabinet 1, thereby driving the waterproof sealing plate 3 to move inward through the horizontal connecting rod 302, tightly fitting the side plate 102 of the cabinet 1, and completing the sealing of the horizontal ventilation slot 2. Conversely, when the regulating motor 405 rotates in the opposite direction, the linkage regulating frame 4 moves upward, driving the slider 401 to release the pressure on the inner linkage slider 304. Under the action of the return spring 303, the waterproof sealing plate 3 slides outward, reopening the ventilation slot and restoring the ventilation and heat dissipation function. An automatic control system can be formed by water level sensors, control modules, etc. When the external water level is detected to rise to the set threshold, the regulating motor 405 is automatically started to close the ventilation slot. After the disaster ends, the ventilation slot is automatically reopened to restore the heat dissipation function.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, preferably, each horizontal ventilation slot 2 on the cabinet 1 is surrounded and fixedly provided with an interlocking sealing ring 201. The interlocking sealing ring 201 is preferably made of rubber or silicone material with good elasticity and weather resistance, and is fixedly installed in the groove structure around the ventilation slot. Correspondingly, an interlocking sealing groove 301 is provided around the inner side of the waterproof sealing plate 3. The shape and size of the interlocking sealing groove 301 match the interlocking sealing ring 201, so that when the waterproof sealing plate 3 is closed, its inner side can be tightly attached to the edge of the horizontal ventilation slot 2, and the interlocking sealing groove 301 and the interlocking sealing ring 201 form an interference fit sealing structure. When the linkage adjustment mechanism drives the waterproof sealing plate 3 to slide inward and attach to the side plate 102 of the cabinet 1, the interlocking sealing groove 301 and the interlocking sealing ring 201 interlock with each other and generate elastic compression deformation, forming a reliable sealing interface, effectively preventing floods, rainwater or moisture from entering the interior of the cabinet 1 through the gap between the ventilation slot and the sealing plate.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, preferably, a fixed guide rod 5 is vertically installed on the outer side of the bottom of the side panel 102 of the cabinet 1. This fixed guide rod 5 is preferably made of corrosion-resistant, high-strength metal or composite material and is vertically fixed to the outer side of the cabinet 1. It is used to guide the detection float 502 to slide stably in the vertical direction. The detection float 502 is slidably connected to the fixed guide rod 5. The detection float 502 has a hollow structure, good buoyancy and weather resistance, and a connecting sleeve 503 is provided inside or at the bottom. The connecting sleeve 503 is connected to the fixed guide rod 5. The guide rod 5 slides, allowing the detection float 502 to slide up and down with changes in water level. A Hall sensor 501 is located at the top of the guide rod 5 to detect changes in magnetic force. Simultaneously, a detection magnet 504 is located at the bottom of the detection float 502, maintaining an initial distance from the Hall sensor 501. When water accumulates, as the water level rises, the detection float 502 rises, causing the detection magnet 504 to move closer to the Hall sensor 501. The Hall sensor 501 detects a stronger magnetic field. The water level changes; when the water level drops, the detection float 502 slides down the fixed guide rod 5 under the action of gravity, the detection magnet 504 moves away from the Hall sensor 501, and the magnetic field strength weakens accordingly. The Hall sensor 501 is connected to the control module inside the distribution cabinet through a signal line. The control module calculates the current water level height based on the change in magnetic field strength and compares it with the preset safe water level threshold. When the water level reaches the set critical value, the control module automatically starts the regulating motor 405, driving the linkage regulating frame 4 to move downward, thereby driving the waterproof sealing plate 3 to close the horizontal ventilation slot 2 through the linkage structure, preventing floodwater from entering the cabinet 1. When the water level drops to a safe range, the control module can automatically or manually control the regulating motor 405 to run in reverse, so that the waterproof sealing plate 3 reopens and restores the ventilation function. Thus, based on the water level data collected by the Hall sensor 501, the control system can automatically determine whether to start the closing action of the waterproof sealing plate 3, realizing the active protection of the distribution cabinet before the flood, and improving the safety and intelligence level of equipment operation.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, preferably, the distribution cabinet has a top-pressure inclined surface 505 on the side of the detection float 502 near the waterproof sealing plate 3. This top-pressure inclined surface 505 is inclined towards the waterproof sealing plate 3. An external linkage slider 306 is connected to the side of the waterproof sealing plate 3 near the detection float 502. This external linkage slider 306 is slidably installed along the side plate 102 of the cabinet 1. Its side has a guide inclined surface 307, which is in contact with and slides against the top-pressure inclined surface 505 on the detection float 502. When water accumulates around the distribution cabinet, as the water level gradually rises, the detection float 502 slides upward along the fixed guide rod 5 under buoyancy. Because the top-pressure inclined surface 505 on the detection float 502 is in contact with the guide inclined surface 307 on the external linkage slider 306 on the side of the waterproof sealing plate 3, the detection float... During the ascent of the float 502, its top pressure slope 505 gradually pushes the guide slope 307 upward, generating a horizontal component force. This causes the external linkage slider 306 to slide outward, and drives the waterproof sealing plate 3 connected to it to slide horizontally, thereby automatically closing the horizontal ventilation slot 2 to prevent floodwater from entering the cabinet 1. When the water level drops, the float 502 slides downward along the fixed guide rod 5 under the action of gravity. The contact pressure between the top pressure slope 505 and the guide slope 307 disappears. Under the action of the reset spring 303, the waterproof sealing plate 3 returns to its original open position, the ventilation slot reopens, and the heat dissipation function of the cabinet 1 is restored. Thus, the above structure can serve as a mechanical emergency backup for the electric linkage structure, or it can be used independently to achieve automatic waterproof sealing function in the absence of power.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, preferably, the distribution cabinet has a horizontal connecting pipe 6 below each horizontal ventilation slot 2 of the cabinet 1. One end of the horizontal connecting pipe 6 has a connecting opening 602 for contact with external water, and the other end is connected to a vertical connecting pipe 601. The top of the vertical connecting pipe 601 is lower than the bottom of the corresponding horizontal ventilation slot 2, ensuring that the linkage mechanism can be activated before the water reaches the ventilation slot. The top of the vertical connecting pipe 601 has a balancing opening 603, and a central sliding sleeve 604 is fixedly installed in the middle of the balancing opening 603 to guide the sliding of the linkage component. Inside the vertical connecting pipe 601, a sliding nested component is installed. A hollow floating plug 7 is provided, which has good buoyancy and sealing performance. It can slide freely up and down in the vertical connecting pipe 601 with the water level. A linkage rod 701 is vertically fixed to the top of the hollow floating plug 7. The linkage rod 701 passes through the central sliding sleeve 604 and can slide along its central hole. A guide roller 605 is provided in the middle of the inner side of the horizontal ventilation slot 2 to guide the path of the traction cable. A connecting traction cable 702 is connected to the top of the linkage rod 701. After the connecting traction cable 702 passes around the guide roller 605, its other end is fixedly connected to the middle position of the inner side of the waterproof sealing plate 3. When water accumulates outside and rises to the required level, the traction cable can be used to guide the water level. When the water level reaches the height of the connecting opening 602, the accumulated water enters the horizontal connecting pipe 6 through the connecting opening 602 and flows into the vertical connecting pipe 601. The water level in the vertical connecting pipe 601 rises accordingly, pushing the hollow floating plug 7 upwards. The hollow floating plug 7 drives the linkage rod 701 to move upwards. The linkage rod 701 pulls the connecting traction cable 702, which, after changing direction via the guide roller 605, pulls the waterproof sealing plate 3 to slide inwards, thereby closing the horizontal ventilation slot 2. This linkage structure has an independent connecting pipe and floating plug assembly below each layer of the horizontal ventilation slot 2 in the distribution cabinet. Therefore, as the water level rises layer by layer, the ventilation slots at different heights can automatically close layer by layer. The system achieves tiered protection by using water level changes to drive the hollow floating plug 7 to rise, which in turn pulls the waterproof sealing plate 3 to close the ventilation slot via the linkage rod 701 and connecting traction cable 702. It is entirely hydraulically driven, requiring no power supply or control system, making it suitable for extreme situations such as power outages or control system failures. Furthermore, since each level of the horizontal ventilation slot 2 has an independent linkage structure below it, when the water level rises to the height of the connecting opening 602 of a certain level of ventilation slot, that level of ventilation slot can automatically close, achieving layer-by-layer closure according to water level height. This prevents floodwater from entering from the lower ventilation slots and rapidly spreading to the upper levels, while retaining a certain amount of ventilation and heat dissipation capacity.

[0026] The flood-proof outdoor power distribution cabinet provided by this invention, through the linkage structure between the linkage adjustment frame 4, the drive slider 401 and the inner linkage slider 304, can automatically trigger the waterproof sealing plate 3 to close the ventilation slot before the water level rises and the cabinet 1 is flooded, effectively preventing floodwater from entering the cabinet 1 and protecting the electrical equipment. Under normal operating conditions, the ventilation slot remains open to ensure the heat dissipation needs of the electrical equipment inside the cabinet 1. When flooding occurs, the waterproof sealing plate 3 can quickly respond and close the ventilation slot, realizing the dual functions of ventilation and waterproofing, and improving the environmental adaptability of the power distribution cabinet.
