Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and more specifically, to a power distribution cabinet with adjustable partitions. Background Technology

[0002] A zoned distribution cabinet is a type of power distribution equipment that divides the cabinet into multiple independent functional areas (i.e., "zones") through its internal structural design. It is used for centralized distribution, control, and protection of different circuits or electrical equipment, while also achieving safety isolation, functional differentiation, and convenient management through zoning. Compared to ordinary distribution cabinets (non-zoned), zoned distribution cabinets achieve spatial isolation through the use of partitions.

[0003] Existing zone distribution cabinets typically allow for the adjustment of partition positions to accommodate different functional areas. However, in practice, to ensure effective isolation between these areas, sealing gaskets are usually installed on the outer perimeter of the partitions. These gaskets are then pressed against the inner wall of the cabinet to reduce the gap between the partitions and the inner wall, thus improving the sealing effect. This results in significant friction between the gaskets and the inner wall, making it inconvenient for operators to adjust the partitions and affecting the zone adjustment capabilities of the distribution cabinet. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable partitioned power distribution cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustable partitioned power distribution cabinet includes a cabinet body and a cabinet door. The cabinet body is provided with a partitioning mechanism. The partitioning mechanism includes vertical plates arranged opposite each other and several partitions that can be raised and lowered between the vertical plates. The partitions have slots on their opposite side walls for the corresponding vertical plates to be inserted into. The vertical plates have multiple positioning slots on their opposite side sides. The partitions have cavities inside, and the cavities have retractable positioning elements that cooperate with the corresponding positioning slots.

[0007] The partition is provided with an expandable and retractable first sealing component on the side wall corresponding to the inner wall of the cabinet, and a tensioning component is provided in the cavity for driving the positioning component to extend and retract. The operation of the tensioning component causes the first sealing component to expand and retract.

[0008] The cavity is also equipped with a fire extinguishing assembly for extinguishing fire on the partition below it. The first sealing assembly is connected to the fire extinguishing assembly to promote the fire extinguishing of fire.

[0009] Preferably, the positioning component includes a partition frame disposed in the cavity, guide posts located on opposite sides of the corresponding slot on the side wall of the partition frame, a positioning plate that slides along the guide posts between the guide posts, a positioning tongue that extends into the slot on the positioning plate, and a spring sleeved on the guide posts for pushing the positioning plate so that the positioning tongue extends into the slot.

[0010] Preferably, the side of the partition facing the cabinet door has a pull-out groove in the middle;

[0011] The tensioning assembly includes fixed pulleys that are rotatably disposed in the cavity and opposite to each other. The tensioning assembly also includes a handle disposed in the pull-out groove. The handle is provided with a mounting post extending into the cavity. The positioning plate is provided with a traction rope that passes around the corresponding fixed pulley and is connected to the mounting post.

[0012] Preferably, the partition has an installation groove on the side wall opposite to the inner wall of the cabinet;

[0013] The first sealing assembly includes an inflatable bladder disposed in a corresponding mounting groove and a telescopic bladder disposed in a partition frame. The telescopic bladder and the inflatable bladder are connected by a first air pipe. A movable compression plate is provided in the partition frame, which compresses the telescopic bladder to allow the gas inside to flow into the inflatable bladder.

[0014] Preferably, the cavity is provided with a driving component, which includes a driving gear mounted on a corresponding fixed pulley, and a driven gear set rotatably mounted on the top wall of the cavity. The driven gear set cooperates with the corresponding driving gear, and a driving gear is provided on the driven gear set. A rack that meshes with the corresponding driving gear is provided on the extrusion plate.

[0015] Preferably, the fire extinguishing assembly includes a powder storage box disposed in a cavity, a leakage hole is provided on the lower side of the partition corresponding to the powder storage box, a diaphragm covering the leakage hole is provided inside the powder storage box, and the powder storage box located on the diaphragm is filled with dry powder.

[0016] Preferably, the telescopic airbag is equipped with a second air pipe that connects to the powder storage box. The second air pipe is equipped with a solenoid valve. When the dry powder in the powder storage box is sprayed out through the leakage hole, the solenoid valve opens to allow the compressed gas in the telescopic airbag to enter the powder storage box, thereby promoting the discharge of the dry powder.

[0017] Preferably, a wire hole is provided on the partition and near the inside of the cabinet, a slidable wire tube is provided in the wire hole, and a second sealing component is provided in the cavity and at the wire hole.

[0018] Preferably, the second sealing assembly includes an inflatable ring bladder fitted over the conduit, and the inflatable ring bladder is connected to the telescopic air bladder via a third air tube.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, when the positioning member extends into the positioning groove to fix the partition, the first sealing component expands and presses against the inner wall of the cabinet, thereby ensuring a seal between the partition and the inner wall of the cabinet, which can better isolate the functional areas from each other; when the positioning member is driven to retract by the stretching component to release it from the positioning groove and release the fixation of the partition, the first sealing component contracts, releasing the mutual pressing between it and the inner wall of the cabinet, thereby reducing the friction between the first sealing component and the inner wall of the cabinet, making it more convenient for the user to drive the partition to rise and fall along the vertical plate.

[0021] 2. In this invention, when a fire occurs in the separated functional area, the fire extinguishing component on the partition above the functional area can extinguish the fire. At the same time, the first sealing component can promote the fire extinguishing of the fire extinguishing component, thereby improving the fire extinguishing effect of the fire extinguishing component.

[0033] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0034] The following is in conjunction with the appendix Figures 1-9 This embodiment will be described in further detail.

[0035] like Figure 1 As shown, in this embodiment, an adjustable partition distribution cabinet includes a cabinet body 100 and a cabinet door 110. The cabinet body 100 is provided with a partitioning mechanism. The cabinet body 100 is the outer shell of the adjustable partition distribution cabinet. The cabinet body 100 has an opening on the front side. The cabinet door 110 is closable at the opening on the front side of the cabinet body 100. The partitioning mechanism is located inside the cabinet body 100 and is used to divide the interior of the cabinet body 100 into different functional areas from top to bottom.

[0036] In this embodiment, the partitioning mechanism includes vertical plates 120 arranged opposite each other and a plurality of partitions 130 that can be raised and lowered between the vertical plates 120. Specifically, in combination with Figure 2 As shown, the vertical plate 120 is set along the height direction of the cabinet 100 and is fixed to the left and right side walls inside the cabinet 100 by screws; wherein, the partition 130 is horizontally installed between the opposite vertical plates 120, and the interior of the cabinet 100 is divided into layers by several partitions 130 to form different functional areas. The size of the functional area formed between adjacent partitions 130 can be adjusted by raising and lowering the partitions 130 along the vertical plates 120.

[0037] In this embodiment, the partition 130 has a slot 301 on the opposite side wall for the corresponding vertical plate 120 to be inserted, and the opposite side of the vertical plate 120 is provided with a plurality of positioning slots 201, wherein the plurality of positioning slots 201 are evenly distributed along the extension direction of the vertical plate 120, and the partition 130 is provided with a cavity 401, and the cavity 401 is provided with a retractable positioning member that cooperates with the corresponding positioning slot 201.

[0038] In this embodiment, the corresponding vertical plate 120 is engaged by the slot 301, which restricts the partition 130 so that it can only move up and down inside the cabinet 100 along the vertical plate 120 during the adjustment process.

[0039] The positioning component is telescopic, allowing it to extend and retract and engage with positioning slots 201 at different positions, thereby enabling the partition 130 to rise and fall and to be fixed between the vertical plates 120.

[0040] In this embodiment, the partition 130 is provided with an expandable and retractable first sealing component 210 on the side wall of the inner wall of the cabinet 100, and the cavity 401 is provided with a tensioning component 220 for driving the positioning component to extend and retract. The tensioning component 220 works to drive the first sealing component 210 to expand and retract.

[0041] In this embodiment, the first sealing component 210 expands when the positioning member extends into the positioning groove 201 to fix the partition 130. This allows it to press against the inner wall of the cabinet 100, ensuring a seal between the partition 130 and the inner wall of the cabinet 100, thus effectively isolating the functional areas. When the positioning member retracts via the stretching component 220, disengaging from the positioning groove 201 to release the fixation of the partition 130, the first sealing component 210 contracts, releasing the pressure between it and the inner wall of the cabinet 100. This reduces the friction between the first sealing component 210 and the inner wall of the cabinet 100, making it easier for the user to move the partition 130 up and down along the vertical plate 120.

[0042] In this embodiment, the cavity 401 is also provided with a fire extinguishing component for extinguishing the fire on the partition 130 below it. The first sealing component 210 is connected to the fire extinguishing component. When a fire occurs in the separated functional area, the fire extinguishing component on the partition 130 above the functional area can extinguish the fire. At the same time, the first sealing component 210 can promote the fire extinguishing of the fire extinguishing component to improve the fire extinguishing effect of the fire extinguishing component.

[0043] In this embodiment, combined with Figure 3 and Figure 4 As shown, the opening of cavity 401 faces the lower side of partition 130, and a cover plate 300 is installed at the opening to facilitate the installation of internal components of cavity 401.

[0044] In this embodiment, the positioning component includes a partition frame 410 fixedly disposed in the cavity 401. Guide posts 411 are provided on the side wall of the partition frame 410 opposite to each other on both sides of the corresponding slot 301. The other end of the guide post 411 is fixedly connected to the side wall of the cavity 401. A positioning plate 420 is provided between the guide posts 411 and slides along the guide posts 411. Specifically, the guide posts 411 are slidably disposed through the positioning plate 420. The positioning plate 420 is provided with a positioning tongue 310 extending into the slot 301. A spring 430 is sleeved on the guide post 411 for pushing the positioning plate 420 so that the positioning tongue 310 extends into the slot 301.

[0045] In this embodiment, the spring 430 enables the positioning plate 420 to always stay away from the partition frame 410, thereby driving the positioning tongue 310 to remain extended, thus realizing the partition 130 is fixedly installed between the vertical plates 120.

[0046] In this embodiment, a pull-out groove 302 is provided in the middle of the side of the partition 130 facing the cabinet door 110;

[0047] The tensioning assembly 220 includes a fixed pulley 440 that is rotatably disposed in the cavity 401. Specifically, the fixed pulley 440 is rotatably mounted on the top wall of the cavity 401 via a rotating shaft. The tensioning assembly 220 also includes a handle 450 disposed in the pull-out groove 302. The handle 450 is provided with a mounting post 710 extending into the cavity 401. The positioning plate 420 is provided with a traction rope 460 that passes around the corresponding fixed pulley 440 and is connected to the mounting post 710.

[0048] In this embodiment, when the positioning tongue 310 is kept extended under the action of the spring 430, the fixed pulley 440 can be rotated by the traction of the traction rope 460, thereby causing the mounting column 710 to extend into the cavity 401, so as to drive the handle 450 to retract into the pull-out groove 302 and be hidden, thereby facilitating the closing of the cabinet door 110, so that the cabinet door 110 fits against the front side of the partition 130, and the isolation effect between functional areas is better.

[0049] When the partition 130 needs to be raised or lowered, the operator holds the partition 130 with one hand and pulls the handle 450 with the other hand to extend it out of the pull slot 302 and hold it there. This causes the mounting column 710 to extend, which in turn drives the traction rope 460 to pull the positioning plate 420 toward the partition frame 410, causing the positioning tongue 310 to retract and release the fixation of the partition 130. At this time, the partition 130 is raised or lowered while being held. After adjusting it to the appropriate position, the handle 450 is released. Under the action of the spring 430, the positioning tongue 310 extends and is engaged in the corresponding positioning slot 201. At the same time, the handle 450 moves into the pull slot 302, thus fixing the partition 130.

[0050] It should be noted that, in order to facilitate the operator to reach into the pull-out groove 302 with his other hand to hold the handle 450, a slot communicating with the pull-out groove 302 is provided on the lower side of the partition 130.

[0051] In this embodiment, in order to limit the pulling distance of the handle 450, a baffle is provided at the end of the mounting post 710 that extends into the cavity 401, and the traction rope 460 is connected to the baffle. When the baffle abuts against the side wall of the cavity 401 located at the pull slot 302, it prevents the mounting post 710 from leaving the cavity 401, thereby limiting the pulling distance of the handle 450.

[0052] Combination Figures 5-8 As shown, in this embodiment, the partition 130 has an installation groove 601 on the side wall opposite to the inner wall of the cabinet 100;

[0053] The first sealing assembly 210 includes an inflatable bladder 320 disposed in a corresponding mounting groove 601 and a telescopic bladder 470 disposed in a partition frame 410. The telescopic bladder 470 and the inflatable bladder 320 are connected by a first air pipe 501. A movable compression plate 480 is provided in the partition frame 410. The compression plate 480 compresses the telescopic bladder 470 so that the gas inside it flows into the space between the inflatable bladders 320.

[0054] In this embodiment, the mounting groove 601 on the rear side of the partition 130 is connected to the mounting grooves 601 on the left and right sides of the partition 130. The inflatable bag 320 is arranged along the extension direction of the corresponding side mounting groove 601, and one side wall of the inflatable bag 320 is fixed to the side wall of the mounting groove 601 by adhesive bonding.

[0055] Specifically, the telescopic airbag 470 includes a corrugated section and a long cylindrical section. The first air pipe 501 is connected to the long cylindrical section. One end face of the telescopic airbag 470 is fixedly connected to the compression plate 480. When the compression plate 480 moves toward the telescopic airbag 470 to compress the corrugated section, the air inside is compressed and enters the corresponding inflation bag 320 through the first air pipe 501, thereby causing the inflation bag 320 to inflate and expand, extending out of the mounting groove 601 and abutting against the inner wall of the cabinet 100. When the compression plate 480 moves away from the telescopic airbag 470 to extend the corrugated section, it can draw the air inside the inflation bag 320 into the telescopic airbag 470, thereby causing the inflation bag 320 to contract into the mounting groove 601 and release its contact with the inner wall of the cabinet 100.

[0056] In this embodiment, a driving member is provided in the cavity 401, which enables the extrusion plate 480 to move within the partition frame 410.

[0057] The driving component includes a drive gear 511 mounted on a corresponding fixed pulley 440, and a driven gear set 520 rotatably mounted on the top wall of the cavity 401. The driven gear set 520 cooperates with the corresponding drive gear 511, and a drive gear 521 is mounted on the driven gear set 520. A rack 530 that meshes with the corresponding drive gear 521 is mounted on the extrusion plate 480.

[0058] With the structure in this embodiment, when the spring 430 drives the positioning tongue 310 to extend, the rotation of the fixed pulley 440 drives the drive gear 511 to rotate, and then, under the action of the driven gear set 520, the compression plate 480 moves towards the telescopic airbag 470, so that the airbag 320 inflates. When the operator pulls the handle 450 to retract the positioning tongue 310, the rotation of the fixed pulley 440 drives the drive gear 511 to rotate, and then, under the action of the driven gear set 520, the compression plate 480 moves away from the telescopic airbag 470, so that the airbag 320 retracts into the mounting groove 601.

[0059] It should be noted that the driven gear set 520 includes driven gears that mesh with each other and are rotatably disposed on the top wall of the cavity 401. One of the two driven gears meshes with the corresponding driving gear 511, and the driving gear 521 is disposed on the other of the two driven gears. Thus, in actual use, the gear ratio between the driving gear 511 and the driven gear can be designed so that the movement distance of the compression plate 480 within the partition frame 410 can be controlled by pulling the traction rope 460 through the handle 450, so as to realize the expansion and contraction of the airbag 320.

[0060] Specifically, there are two partition frames 410 arranged opposite each other. Limiting grooves are opened on the opposite side walls of the partition frames 410. The extrusion plates 480 in the two partition frames 410 are connected by connecting blocks passing through the limiting grooves to realize the sliding installation of the extrusion plates 480 in the partition frames 410. In actual use, the rack 530 is fixedly connected to the connecting block along the extension direction of the partition frame 410 and always maintains engagement with the drive gear 521.

[0061] In this embodiment, the fire extinguishing component includes a powder storage box 490 disposed in the cavity 401. A leakage hole 303 is provided on the lower side of the partition 130 corresponding to the powder storage box 490. Specifically, the leakage hole 303 is disposed on the cover plate 300. A diaphragm 491 covering the leakage hole 303 is provided inside the powder storage box 490. The powder storage box 490 located on the diaphragm 491 is filled with dry powder.

[0062] In this embodiment, the powder storage box 490 has an opening at one end, which faces the cover plate 300. A diaphragm 491 is disposed at the opening, allowing dry powder to be stored in the powder storage box 490. When a fire occurs in this functional area, the flame burns to the diaphragm 491 through the leakage hole 303, causing the diaphragm 491 to rupture. This allows the dry powder in the powder storage box 490 to fall through the leakage hole 303 to cover the fire location, thereby achieving a fire extinguishing effect.

[0063] In this embodiment, the telescopic airbag 470 is provided with a second air pipe 540 that connects to the powder storage box 490. The second air pipe 540 is provided with a solenoid valve 541. When the dry powder in the powder storage box 490 is sprayed out through the leakage hole 303, the solenoid valve 541 opens to allow the compressed gas in the telescopic airbag 470 to enter the powder storage box 490, so as to promote the discharge of the dry powder.

[0064] In actual use, when the diaphragm 491 ruptures to release dry powder, the air pressure in the powder storage box 490 is the same as the air pressure in the functional area. However, because the extrusion plate 480 extrudes the telescopic airbag 470, the air pressure in the telescopic airbag 470 is greater than the air pressure in the powder storage box 490. Therefore, when the powder storage box 490 releases dry powder, the opening of the solenoid valve 541 allows the compressed air in the telescopic airbag 470 to enter the powder storage box 490 through the second air pipe 540, thereby increasing the air pressure in the powder storage box 490. This allows the dry powder in the powder storage box 490 to be released through the leakage hole 303, thereby improving the fire extinguishing effect of the fire extinguishing assembly.

[0065] In this embodiment, combined with Figure 9 As shown, in order to control the opening and closing of the solenoid valve 541, a controller is provided in the cavity 401. The controller is electrically connected to the solenoid valve 541. A pressure sensor 910 is provided in the powder storage box 490. The pressure sensor 910 is electrically connected to the controller. With the above structure, when the diaphragm 491 ruptures, the dry powder falls onto the cover plate 300 and lands on the pressure sensor 910, thereby enabling the pressure sensor 910 to detect the weight change. At this time, the controller controls the solenoid valve 541 to open.

[0066] In order to provide power to the controller, solenoid valve 541 and pressure sensor 910, a battery is provided in cavity 401 for supplying power to the controller, solenoid valve 541 and pressure sensor 910.

[0067] In this embodiment, to prevent the dry powder from shaking and affecting the operation of the pressure sensor 910 during the adjustment of the partition 130, a mounting part 901 is provided opposite to each other in the powder storage box 490. The two ends of the diaphragm 491 are fixedly mounted on the mounting part 901 on the corresponding side, thereby forming a space for mounting the pressure sensor 910 between the mounting part 901, the diaphragm 491, the powder storage box 490 and the cover plate 300. The pressure sensor 910 is mounted on the cover plate 300 in this space. Through the obstruction of the mounting part 901 and the diaphragm 491, the shaking of the dry powder during the raising and lowering of the partition 130 can be prevented from affecting the operation of the pressure sensor 910. The diaphragm 491 is tensioned and installed between the cover plate 300 and the mounting part 901. At this time, when any part of the diaphragm 491 breaks, the entire diaphragm 491 can break, so that when the dry powder is sprayed out, it can flow into the pressure sensor 910, so that the pressure sensor 910 can detect the weight change.

[0068] In practical use, when components in adjacent functional areas are connected by cables, a wire hole 231 is opened on the partition 130 for the cables to pass through. In the prior art, in order to facilitate the centralized sealing of cables passing through the wire hole 231, the cables are passed through the same conduit and the cables inside the conduit are sealed. Then the conduit is passed through the wire hole 231. In order to seal the gap between the conduit and the wire hole 231, the conduit is usually fixed to the partition 130. At this time, when the partition 130 needs to be adjusted, the fixed conduit makes it easy for the cables to be pulled when the partition 130 is raised or lowered, making it impossible to raise or lower the partition 130.

[0069] In this embodiment, in order to solve the problem that the installation of cables affects the lifting and lowering of the partition 130, a cable hole 231 is provided on the partition 130 and on the inner side near the cabinet 100. A sliding cable tube is provided in the cable hole 231, and a second sealing component is provided in the cavity 401 and located at the cable hole 231.

[0070] In this embodiment, the second sealing assembly includes an inflatable ring bladder 550 fitted over the conduit tube, and the inflatable ring bladder 550 and the telescopic air bladder 470 are connected by a third air tube 551.

[0071] In this embodiment, the upper and lower sides of the inflatable ring bladder 550 are fixedly installed on the corresponding side walls of the cavity 401. Under the action of the third air tube 551, when the telescopic air bladder 470 is compressed to inflate the inflatable air bladder 320, the gas inside the telescopic air bladder 470 can be compressed into the inflatable ring bladder 550, thereby inflating the inflatable ring bladder 550 to tighten and fit the outer wall of the conduit, thereby improving the sealing performance of the conduit passing through the conduit hole 231 and improving the isolation effect between functional areas. When the telescopic air bladder 470 extends to contract the inflatable air bladder 320, it can also drive the inflatable ring bladder 550 to contract, releasing the tension on the conduit, thereby making it easier for the partition 130 to rise and fall along the conduit, which is beneficial for the adjustment of the partition 130.

[0072] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
