Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with adjustable partitions. Background Art

[0002] A zoned power distribution cabinet is a type of power distribution equipment whose internal structure divides the cabinet into multiple independent functional areas (i.e., "zones"). This cabinet is used to centrally distribute, control, and protect different circuits or electrical equipment. These zones also provide safety isolation, functional differentiation, and ease of management. Compared to ordinary (non-zoned) power distribution cabinets, zoned power distribution cabinets achieve spatial isolation through the use of partitions.

[0003] In order to adjust the space size of independent functional areas, existing partition distribution cabinets can usually lift and lower the position of the partition to complete the adjustment of the space size of the functional areas; however, in actual use, in order to ensure the isolation effect between independent functional areas, sealing gaskets are usually provided on the outer peripheral side walls of the partitions, and the sealing gaskets are used to fit the inner wall of the cabinet to reduce the gap between the partitions and the inner wall of the cabinet and improve the sealing effect. As a result, there is a large friction force between the sealing gaskets and the inner wall of the cabinet due to extrusion, which makes it inconvenient for operators to perform the partition lifting and adjusting operations, thereby affecting the partition adjustment of the partition distribution cabinet.

DETAILED DESCRIPTION

[0026] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0027] The following is combined with Figures 1-9 This embodiment is described in further detail.

[0028] like Figure 1 As shown, in this embodiment, a power distribution cabinet with adjustable partitioning includes a cabinet body 100 and a cabinet door 110, and a partitioning mechanism is provided in the cabinet body 100; wherein, the cabinet body 100 is the outer shell part of the power distribution cabinet with adjustable partitioning, the front side of the cabinet body 100 is provided with an opening, and the cabinet door 110 is openably provided at the front side opening of the cabinet body 100, wherein the partitioning mechanism is provided inside the cabinet body 100, and is used to separate the inside of the cabinet body 100 from top to bottom into different functional areas.

[0029] In this embodiment, the partition mechanism includes vertical plates 120 arranged opposite to each other and a plurality of partition plates 130 which can be lifted and lowered between the vertical plates 120. Figure 2 As shown, the vertical plate 120 is arranged along the height direction of the cabinet body 100, and is relatively fixed to the left and right side walls inside the cabinet body 100 by screws; wherein, the partition 130 is horizontally installed between the relative vertical plates 120, and the interior of the cabinet body 100 is layered by a number of partitions 130 to form different functional areas, wherein, by raising and lowering the partition 130 along the vertical plate 120, the size of the functional area formed between adjacent partitions 130 is adjusted.

[0030] In this embodiment, slots 301 for corresponding risers 120 to be inserted into are formed on the opposite side walls of the partition 130, and a plurality of positioning slots 201 are arranged on the opposite side surfaces of the risers 120. The plurality of positioning slots 201 are evenly distributed along the extension direction of the risers 120. A cavity 401 is provided in the partition 130, and a retractable positioning member is provided in the cavity 401 and cooperates with the corresponding positioning slot 201. In this embodiment, the corresponding vertical plate 120 is engaged by the card slot 301, so that the partition 130 is restricted so that it can only be raised and lowered along the vertical plate 120 inside the cabinet 100 during adjustment. The positioning member is configured to be telescopic, so that the positioning member can be telescoped and inserted into the positioning slots 201 at different positions, thereby enabling the partition 130 to be raised and lowered, and fixed between the vertical plates 120 .

[0031] In this embodiment, a first expandable and contractible sealing component 210 is provided on the side wall of the partition 130 corresponding to the inner wall of the cabinet 100, and a tensile component 220 for driving the positioning member to expand and contract is provided in the cavity 401. The operation of the tensile component 220 drives the first sealing component 210 to expand and contract. In this embodiment, through the provision of the first sealing component 210, when the positioning member extends into the positioning groove 201 to fix the partition 130, the first sealing component 210 expands and can be squeezed against the inner wall of the cabinet 100, thereby ensuring the sealing of the gap between the partition 130 and the inner wall of the cabinet 100, that is, the functional areas can be better isolated from each other; when the positioning member is driven to retract by the stretching component 220 to disengage from the positioning groove 201 to release the fixation of the partition 130, the first sealing component 210 contracts and releases the mutual squeezing between it and the inner wall of the cabinet 100, thereby reducing the friction between the first sealing component 210 and the inner wall of the cabinet 100, making it more convenient for the user to drive the partition 130 to rise and fall along the vertical plate 120.

[0032] In this embodiment, a fire extinguishing assembly is also provided in the cavity 401 for extinguishing a fire on the partition 130 below it. The first sealing assembly 210 is connected to the fire extinguishing assembly. When a fire occurs in the separated functional area, the fire extinguishing assembly on the partition 130 above the functional area can extinguish the fire. At the same time, the first sealing assembly 210 can promote the fire extinguishing assembly to extinguish the fire, so as to improve the fire extinguishing effect of the fire extinguishing assembly.

[0033] In this embodiment, combined with Figure 3 and Figure 4 As shown, the opening of the cavity 401 faces the lower side of the partition 130, wherein a cover plate 300 is installed at the opening to facilitate the installation of components in the cavity 401; In this embodiment, the positioning member includes a partition frame 410 fixed in the cavity 401, and guide columns 411 are relatively provided on the side walls of the partition frame 410 and located on both sides of the corresponding card slot 301, wherein the other end of the guide column 411 is fixedly connected to the side wall of the cavity 401, and a positioning plate 420 sliding along the guide column 411 is provided between the guide columns 411. Specifically, the guide column 411 slides through the positioning plate 420, and the positioning plate 420 is provided with a positioning tongue 310 extending into the card slot 301, and the guide column 411 is provided with a spring 430 for pushing the positioning plate 420 to enable the positioning tongue 310 to extend into the card slot 301.

[0034] In this embodiment, the spring 430 can keep the positioning plate 420 away from the partition frame 410 at all times, thereby driving the positioning tongue 310 to remain in an extended state, that is, the partition plate 130 is fixedly installed between the vertical plates 120.

[0035] In this embodiment, a drawer slot 302 is provided at the middle portion of the side of the partition 130 facing the cabinet door 110; The stretching assembly 220 includes a fixed pulley 440 that is relatively and rotatably arranged in the cavity 401. Specifically, the fixed pulley 440 is rotatably installed on the top wall of the cavity 401 through a rotating shaft. The stretching assembly 220 also includes a handle 450 arranged in the pulling groove 302. The handle 450 is provided with a mounting column 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 column 710.

[0036] In this embodiment, under the action of the spring 430, the positioning tongue 310 remains in an extended state, and the traction of the traction rope 460 can cause the fixed pulley 440 to rotate, thereby extending the mounting column 710 into the cavity 401, driving 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 the front side of the partition 130, and the isolation effect between the functional areas is better.

[0037] 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-out slot 302 and hold it, thereby extending the mounting column 710, driving the traction rope 460 to pull the positioning plate 420 toward the partition frame 410, so that the positioning tongue 310 retracts and releases the fixation of the partition 130. At this time, the partition 130 is supported and raised and adjusted to the appropriate position, and the handle 450 is released. Under the action of the spring 430, the positioning tongue 310 extends and is stuck in the corresponding positioning slot 201. At the same time, the handle 450 moves into the pull-out slot 302 to fix the partition 130.

[0038] It should be noted that, in order to facilitate the operator to reach into the drawer slot 302 with his other hand to hold the handle 450, a notch communicating with the drawer slot 302 is opened on the lower side of the partition 130; In this embodiment, in order to limit the pulling distance of the handle 450, a baffle is provided at the end of the mounting column 710 extending 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-out groove 302, it prevents the mounting column 710 from separating from the cavity 401, thereby limiting the pulling distance of the handle 450.

[0039] Combine Figure 5-Figure 8 As shown, in this embodiment, a mounting groove 601 is provided on the side wall of the partition 130 opposite to the inner wall of the cabinet 100; The first sealing assembly 210 includes an inflatable bag 320 arranged in the corresponding mounting groove 601 and a telescopic air bag 470 arranged in the bulkhead 410. The telescopic air bag 470 and the inflatable bag 320 are connected by a first air pipe 501. A movable extrusion plate 480 is provided in the bulkhead 410. The extrusion plate 480 squeezes the telescopic air bag 470 so that the gas inside it flows into the inflatable bag 320.

[0040] 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, wherein the inflatable bag 320 is arranged along the extension direction of the corresponding side mounting groove 601, and a side wall of the inflatable bag 320 is fixed to the side wall of the mounting groove 601 by bonding; Specifically, the telescopic airbag 470 includes a corrugated section and a long cylindrical section, and the first air tube 501 is connected to the long cylindrical section, wherein one end face of the telescopic airbag 470 is fixedly connected to the extrusion plate 480. When the extrusion plate 480 moves toward the telescopic airbag 470 to squeeze the corrugated section to compress it, the air inside it is compressed and enters the corresponding inflatable bag 320 through the first air tube 501, thereby inflating the inflatable bag 320 and expanding it, so that it extends out of the mounting groove 601 and abuts against the inner wall of the cabinet 100; when the extrusion plate 480 moves away from the telescopic airbag 470 to drive the corrugated section to stretch, it can suck the air inside the inflatable bag 320 into the telescopic airbag 470, thereby causing the inflatable bag 320 to shrink into the mounting groove 601 to release the fit to the inner wall of the cabinet 100.

[0041] In this embodiment, a driving member is provided in the cavity 401, and the driving member can move the extrusion plate 480 in the bulkhead 410; The driving member includes a driving gear 511 provided on the corresponding fixed pulley 440, and the driving member also includes a driven gear group 520 rotatably provided on the top wall of the cavity 401, the driven gear group 520 cooperates with the corresponding driving gear 511, and a driving gear 521 is provided on the driven gear group 520, and a rack 530 meshing with the corresponding driving gear 521 is provided on the extrusion plate 480.

[0042] Through the structure of this embodiment, in actual use, when the spring 430 drives the positioning tongue 310 to extend, the rotation of the fixed pulley 440 drives the driving gear 511 to rotate, and then under the action of the driven gear set 520, the extrusion plate 480 is moved toward the telescopic airbag 470, so that the inflatable bag 320 is inflated and expanded; when the operator pulls the handle 450 to retract the positioning tongue 310, the rotation of the fixed pulley 440 drives the driving gear 511 to rotate, and then under the action of the driven gear set 520, the extrusion plate 480 is moved away from the telescopic airbag 470, so that the inflatable bag 320 is contracted into the mounting groove 601.

[0043] It should be noted that the driven gear set 520 includes driven gears that are meshed with each other and rotatably arranged on the top wall of the cavity 401. One of the two driven gears is meshed with the corresponding driving gear 511, and the driving gear 521 is arranged on the other of the two driven gears. Therefore, in actual use, the gear ratio between the driving gear 511 and the driven gear can be designed so that the moving distance of the extrusion plate 480 in the bulkhead 410 can be controlled by pulling the traction rope 460 through the handle 450 to realize the expansion and contraction of the inflatable bag 320.

[0044] Specifically, two partition frames 410 are arranged opposite to each other, and limiting grooves are provided 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; when it is actually used, the rack 530 is fixedly connected to the connecting block along the extension direction of the partition frame 410, and always remains engaged with the driving gear 521.

[0045] In this embodiment, the fire extinguishing assembly includes a powder storage box 490 arranged in the cavity 401, and a leakage hole 303 is opened on the lower side of the partition 130 corresponding to the powder storage box 490. Specifically, the leakage hole 303 is arranged on the cover plate 300, and a diaphragm 491 covering the leakage hole 303 is provided in the powder storage box 490, and the powder storage box 490 located on the diaphragm 491 is filled with dry powder.

[0046] During actual use of this embodiment, an opening is provided at one end of the powder storage box 490, with the opening facing the cover plate 300, wherein a diaphragm 491 is provided at the opening, and dry powder can be stored in the powder storage box 490 through the diaphragm 491; when a fire occurs in the functional area, when the flame burns the diaphragm 491 through the leakage hole 303, the diaphragm 491 ruptures, and the dry powder in the powder storage box 490 can fall through the leakage hole 303 to cover the fire position, thereby achieving a fire extinguishing effect.

[0047] In this embodiment, a second air pipe 540 connected to the powder storage box 490 is provided on the telescopic airbag 470, and an electromagnetic valve 541 is provided on the second air pipe 540. When the dry powder in the powder storage box 490 is sprayed out through the leakage hole 303, the electromagnetic valve 541 opens to allow the compressed gas in the telescopic airbag 470 to enter the powder storage box 490 to promote the discharge of dry powder.

[0048] During actual use of this embodiment, when the diaphragm 491 ruptures to spray dry powder, the air pressure in the powder storage box 490 is the same as the air pressure in the functional area. However, since the extrusion plate 480 squeezes the telescopic airbag 470, the air pressure in the telescopic airbag 470 can be greater than the air pressure in the powder storage box 490. Therefore, when the powder storage box 490 sprays dry powder, the solenoid valve 541 is opened to allow 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 so that the dry powder in the powder storage box 490 can be sprayed out through the leak hole 303, thereby improving the fire extinguishing effect of the fire extinguishing assembly.

[0049] 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, and the controller is electrically connected to the solenoid valve 541. A pressure sensor 910 is provided in the powder storage box 490, and the pressure sensor 910 is electrically connected to the controller. Through the above structure, when the diaphragm 491 ruptures, the dry powder falls onto the cover plate 300 and can fall 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; In order to power the controller, the solenoid valve 541 and the pressure sensor 910 , a battery for powering the controller, the solenoid valve 541 and the pressure sensor 910 is provided in the cavity 401 .

[0050] In this embodiment, in order to prevent the shaking of dry powder from affecting the operation of the pressure sensor 910 during the adjustment of the partition 130, mounting parts 901 are relatively arranged in the powder storage box 490, and the two ends of the diaphragm 491 are fixedly mounted on the mounting parts 901 on the corresponding sides, so that a space for installing the pressure sensor 910 is formed between the mounting part 901, the diaphragm 491, the powder storage box 490 and the cover plate 300. The pressure sensor 910 is installed on the cover plate 300 in the space. Through the obstruction of the mounting part 901 and the diaphragm 491, the shaking of dry powder can be prevented from affecting the operation of the pressure sensor 910 when the partition 130 is raised or lowered. 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 is ruptured, the entire diaphragm 491 can be ruptured, so that when the dry powder is sprayed out, it can flow into the pressure sensor 910, so that the pressure sensor 910 detects the weight change. In actual use of this embodiment, when components in adjacent functional areas are connected by cables, a threading hole 231 is opened on the partition 130 for the threading of the cables. In the prior art, in order to facilitate centralized sealing of the cables passing through the threading holes 231, the cables are passed through the same threading tube, and the cables in the threading tube are blocked. Then, the threading tube is passed through the threading hole 231. In order to seal the gap between the threading tube and the threading hole 231, the threading tube is usually fixed to the partition 130. In this case, when the partition 130 needs to be adjusted, the fixed threading tube causes the partition 130 to be raised or lowered, which easily causes the cables to be pulled, making the partition 130 unable to be raised or lowered. In this embodiment, in order to solve the problem of cables affecting the lifting and lowering of the partition 130, a wire threading hole 231 is opened on the partition 130 and close to the inner side of the cabinet 100. A sliding wire threading tube is provided in the wire threading hole 231, and a second sealing component is provided in the cavity 401 and located at the wire threading hole 231.

[0051] In this embodiment, the second sealing assembly includes an inflatable ring bag 550 sleeved outside the threading tube, and the inflatable ring bag 550 is connected to the telescopic air bag 470 through a third air pipe 551.

[0052] In this embodiment, the upper and lower sides of the inflation ring bag 550 are fixedly installed on the corresponding side walls of the cavity 401. Under the action of the third air pipe 551, when the telescopic air bag 470 is compressed to inflate the inflation bag 320, the gas in the telescopic air bag 470 can be compressed into the inflation ring bag 550, and then the inflation ring bag 550 is inflated to expand, so as to inflate and tightly fit the outer wall of the threading pipe, thereby improving the sealing performance of the threading pipe at the threading hole 231, and improving the isolation effect between the functional areas; when the telescopic air bag 470 is stretched to contract the inflation bag 320, the inflation ring bag 550 can also be contracted to release the inflation of the threading pipe, so that the partition plate 130 is conveniently lifted along the threading pipe, and the lifting adjustment of the partition plate 130 is facilitated.

[0053] In summary, the above only describes the preferred embodiments of the present application, and any equivalent changes and modifications made according to the scope of the patent application of the present application shall be within the scope of the present application.
