Description

Technical Field

[0001] The present application relates to the field of power transformation facilities, and in particular to a splicing and combination structure of a feeder cabinet. Background Art

[0002] At present, in the field of substation equipment, feeder cabinets are often used in substations to distribute the power bus to different loads for use. Feeder cabinets can not only effectively distribute electric energy, but also provide safety protection for power-consuming equipment, and can also monitor electric energy in a timely manner to ensure the safety of the entire circuit.

[0003] Therefore, when the number of loads is large, multiple feeder cabinets need to be installed in the substation to meet the one-to-one correspondence with the loads. Therefore, in order to facilitate the installation and reinforcement between multiple feeder cabinets, vertical guide rails are set on both sides of the feeder cabinets, and the fixing and installation are completed by passing bolts and nuts through the guide rails of two different feeder cabinets.

[0004] With regard to the above-mentioned related technologies, when operators fix the feeder cabinets, the two feeder cabinets are easily misaligned, resulting in the feeder cabinets not being located on the same horizontal plane after the bolts are tightened, and the operators need to enter the cabinet from the back to tighten the bolts in sequence. Since the internal space of the substation is very limited, it is usually necessary to complete the installation of several feeder cabinets before the feeder cabinets are installed into the substation, and then move them into the substation together, which makes the installation process more difficult. Utility Model Content

[0005] In order to facilitate installation and fixation of multiple drawer-type wiring cabinets after they are placed inside a substation, the present application provides a feeder cabinet splicing combination structure.

[0006] The present application provides a feeder cabinet splicing and assembly structure, which adopts the following technical solution:

[0007] A feeder cabinet splicing combination structure includes a feeder cabinet, a vertical mounting rail is provided on one side of the feeder cabinet, a plurality of plug-in blocks are provided in the vertical direction of the mounting rail, a locking rail is provided on the side of the feeder cabinet away from the mounting rail, a plurality of slots are provided in the vertical direction of the locking rail, the slots correspond to the plug-in blocks one by one, the feeder cabinet is provided with a push rod for fixing the plug-in blocks in the slots, a rotating shaft corresponding to the plug-in blocks one by one is provided in the length direction of the mounting rail, the plug-in blocks are rotatably connected to the rotating shaft, and decorative panels are detachably connected on both horizontal sides of the feeder cabinet.

[0008] By adopting the above technical solution, when multiple feeder cabinets need to be combined, the operator removes the decorative panel, then rotates the plug-in block along the rotating shaft, changes the position of the plug-in block through the push rod, and then moves the plug-in block into the slot to fix the plug-in block. This effectively enables the operator to complete the connection between multiple feeder cabinets without entering the feeder cabinet, which is convenient for placing the feeder cabinet into the substation and then connecting it.

[0009] Optionally, the slot includes a guide portion and a locking portion, the insert block slides up and down along the rotating shaft, the guide portion is horizontally arranged, and a vertical locking portion is provided at one end of the guide portion. When the insert block enters the slot, the insert block reaches the locked portion along the guide portion, and the insert block slides along the locking portion to the bottom of the locking portion.

[0010] By adopting the above technical solution, when the plug-in block is fixed, the plug-in block enters the interior of the slot along the guide portion, and then the operator pushes the push rod to push the plug-in block into the locking portion to complete the fixation between the plug-in block and the slot. During this process, the plug-in block moves up and down along the rotating shaft, so that the plug-in block can enter the interior of the slot more, effectively increasing the installation strength between the slot and the plug-in block.

[0011] Optionally, the mounting rail is provided with a placement groove for accommodating the plug, an avoidance groove is provided in the middle of the plug, the rotating shaft is provided with a torsion spring, the torsion spring is located in the avoidance groove, one end of the torsion spring abuts against the placement groove, and the other end of the torsion spring abuts against a side of the plug close to the placement groove, and a limit block is provided on the side of the rotating shaft close to the inner side of the feeder cabinet, and when the plug abuts against the limit block, the two ends of the torsion spring are at ninety degrees.

[0012] By adopting the above technical solution, the position of the plug is limited by the torsion spring and the limit block, so that the plug can automatically reach the required installation position when in use. When no splicing is required, the plug is located in the avoidance groove, and the position of the plug is limited by the decorative panel, which effectively allows the plug to be rotated out to a fixed position.

[0013] Optionally, the push rod is vertically arranged and is provided with a plurality of push claws. The end of the push claw close to the plug block abuts against the rotating shaft, the push claw abuts against the bottom surface of the plug block, the push claw and the plug block correspond to each other, and a locking assembly for fixing the position of the push rod is provided on the lower side of the push rod.

[0014] By adopting the above technical solution, when the plug needs to be pushed into the slot, the push rod is moved upward so that the push rod can drive the push claw at the same time, and the position of the plug is changed by the upward movement of the push claw. When the movement is in place, the position of the push rod is fixed by the locking assembly, which effectively realizes the connection between the two feeder cabinets even if the operator is not outside the feeder cabinet.

[0015] Optionally, the locking assembly includes a lever and a ratchet, the lever is rotatably connected to the feeder cabinet in the vertical direction, one end of the lever extends toward the interior of the feeder cabinet, and the other end of the lever extends toward a side away from the interior of the feeder cabinet, the side of the lever close to the interior of the feeder cabinet is hinged to the lever, and a pedal is provided on the side of the lever away from the interior of the feeder cabinet, and the ratchet is located at the connection between the lever and the feeder cabinet.

[0016] By adopting the above technical solution, the operator presses the pedal downward to move the other end of the lever upward, and pushes the push rod upward through the lever. At this time, the ratchet rotates with the movement of the lever. When the push rod moves into place, the operator releases the pedal and completes the limiting and locking of the lever through the ratchet. When the two feeder cabinets need to be separated, the lever can be rotated by simply releasing the reset trigger of the ratchet, which further optimizes the operating difficulty of the operator in fixing the two feeder cabinets.

[0017] Optionally, the rotating shaft sleeve is provided with a spring, the upper end surface of the spring abuts against the inner wall of the placement groove, and the lower end surface of the spring abuts against the upper end surface of the push claw

[0018] By adopting the above technical solution, when the operator needs to separate the two feeder cabinets, when the push rod moves downward, the spring pushes the plug block to move downward along the rotating shaft, so that it leaves the locking part and enters the guide part. At this time, the operator only needs to move one of the feeder cabinets forward and backward to complete the separation of the two feeder cabinets.

[0019] Optionally, a locking bolt is provided on a side of the decorative plate away from the mounting rail, the feeder cabinet is provided with threaded holes corresponding to the locking bolts one by one, and the feeder cabinet is provided with a slide rail slidably connected to the decorative plate.

[0020] By adopting the above technical solution, the operator can flexibly install the decorative panel by pulling it along the mounting rail. When the decorative panel needs to be removed, the locking bolt is removed to achieve pulling and pulling of the decorative panel, which effectively enables the operator to install and remove the feeder cabinet decorative panel.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] The embodiment of the present application discloses a splicing and assembly structure of a feeder cabinet 1 .

[0033] Reference Figures 1 to 6A splicing and combination structure of a feeder cabinet 1 includes a feeder cabinet 1, a vertical mounting rail 2 is provided on one side of the feeder cabinet 1, a plurality of plug-in blocks 21 are provided in the vertical direction of the mounting rail 2, a locking rail 4 is provided on the side of the feeder cabinet 1 away from the mounting rail 2, a plurality of slots are provided in the vertical direction of the locking rail 4, the slots correspond to the plug-in blocks 21 one by one, the feeder cabinet 1 is provided with a push rod 3 for fixing the plug-in blocks 21 in the slots, a rotating shaft 24 corresponding to the plug-in blocks 21 in the length direction of the mounting rail 2, the plug-in blocks 21 are rotatably connected to the rotating shaft 24, and decorative panels 11 are detachably connected on both horizontal sides of the feeder cabinet 1. When multiple feeder cabinets 1 need to be combined, the operator removes the decorative panel 11, then unscrews the plug-in block 21 along the rotating shaft 24, changes the position of the plug-in block 21 through the push rod 3, and then moves the plug-in block 21 into the slot to fix the plug-in block 21. This effectively enables the operator to complete the connection between multiple feeder cabinets 1 without entering the feeder cabinet 1, making it convenient to place the feeder cabinet 1 into the substation and then connect it.

[0034] In order to further strengthen the installation strength between the slot and the plug-in block 21. The slot includes a guide portion 41 and a locking portion 42. The plug-in block 21 slides up and down along the rotating shaft 24. The guide portion 41 is horizontally arranged. A vertical locking portion 42 is arranged at one end of the guide portion 41. When the plug-in block 21 enters the slot, the plug-in block 21 reaches the locked portion 42 along the guide portion 41, and the plug-in block 21 slides along the locking portion 42 to the bottom of the locking portion 42. When the plug-in block 21 is fixed, the plug-in block 21 enters the slot along the guide portion 41, and then the operator pushes the push rod 3 to push the plug-in block 21 into the locking portion 42 to complete the fixation between the plug-in block 21 and the slot. In this process, the plug-in block 21 moves up and down along the rotating shaft 24, so that the plug-in block 21 can enter the slot more, and finally the installation strength between the slot and the plug-in block 21 is increased.

[0035] In order to ensure that the plug-in block 21 can reach the correct plug-in position every time and reduce the operator's adjustment process. The mounting rail 2 is provided with a placement slot for accommodating the plug-in block 21, and an avoidance slot is provided in the middle of the plug-in block 21. The rotating shaft 24 is provided with a torsion spring 22, which is located in the avoidance slot. One end of the torsion spring 22 abuts against the placement slot, and the other end of the torsion spring 22 abuts against the side of the plug-in block 21 close to the placement slot. A limit block 25 is provided on the side of the rotating shaft 24 close to the inner side of the feeder cabinet 1. When the plug-in block 21 abuts against the limit block 25, the two ends of the torsion spring 22 are at ninety degrees. The position of the plug-in block 21 is limited by the torsion spring 22 and the limit block 25, so that the plug-in block 21 can automatically reach the required installation position when in use. When no splicing is required, the plug-in block 21 is located in the avoidance slot. The position of the plug-in block 21 is limited by the decorative panel 11, so that the plug-in block 21 can be effectively rotated out to a fixed position.

[0036] In order to facilitate the display of the mounting rail 2 in this article, Figure 2The decorative panel 11 in the related enlarged schematic diagram has been hidden. At this time, the torsion spring 22 presses the plug 21 against the decorative panel 11. The decorative panel 11 limits the plug 21 so that it is always located inside the placement groove, and the torsion spring 22 remains in a compressed state.

[0037] In order to facilitate the operator to insert the plug block 21 into the slot. The push rod 3 is arranged vertically, and the push rod 3 is provided with a plurality of push claws 31. The end of the push claw 31 close to the plug block 21 abuts against the rotating shaft 24, and the push claw 31 abuts against the bottom surface of the plug block 21. The push claw 31 corresponds to the plug block 21. The lower side of the push rod 3 is provided with a locking assembly for fixing the position of the push rod 3. When the plug block 21 needs to be pushed into the slot, the push rod 3 is moved upward so that the push rod 3 can drive the push claw 31 at the same time. The position of the plug block 21 is changed by the upward movement of the push claw 31. When the movement is in place, the position of the push rod 3 is fixed by the locking assembly, which effectively realizes the connection between the two feeder cabinets 1 even if the operator is not outside the feeder cabinet 1.

[0038] In this embodiment, a lever 32 and a ratchet 33 are used as a locking assembly for locking the push rod 3, and other structures that can lock the push rod 3 can also be used. The lever 32 is rotatably connected to the feeder cabinet 1 in the vertical direction, one end of the lever 32 extends toward the inside of the feeder cabinet 1, and the other end of the lever 32 extends toward a side away from the inside of the feeder cabinet 1. The side of the lever 32 close to the inside of the feeder cabinet 1 is hinged to the lever 32, and the side of the lever 32 away from the inside of the feeder cabinet 1 is provided with a pedal 34, and the ratchet 33 is located at the connection between the lever 32 and the feeder cabinet 1. The operator steps on the pedal 34 downward to move the other end of the lever 32 upward, and pushes the push rod 3 upward through the lever 32. At this time, the ratchet 33 rotates with the movement of the lever 32. When the push rod 3 moves into place, the operator releases the pedal 34 and completes the limiting and locking of the lever 32 through the ratchet 33. When the two feeder cabinets 1 need to be separated, the lever 32 can be rotated by simply releasing the reset trigger of the ratchet 33, which further optimizes the operating difficulty of the operator in fixing the two feeder cabinets 1.

[0039] In order to facilitate the operator to disassemble the already spliced ​​feeder cabinets 1, the rotating shaft 24 is sleeved with a spring 23, the upper end surface of the spring 23 abuts against the inner wall of the placement groove, and the lower end surface of the spring 23 abuts against the upper end surface of the push claw 31. When the operator needs to separate the two feeder cabinets 1, when the push rod 3 moves downward, the spring 23 pushes the plug block 21 to move downward along the rotating shaft 24, so that it leaves the locking portion 42 and enters the guide portion 41. At this time, the operator only needs to move one of the feeder cabinets 1 forward and backward to complete the separation of the two feeder cabinets 1.

[0040] After the installation of the feeder cabinet 1 group is completed, the two sides need to be sealed with plates for beautification and decoration to reduce dust from entering the feeder cabinet 1. A locking bolt is provided on the side of the decorative panel 11 away from the mounting rail 2, and the feeder cabinet 1 is provided with threaded holes corresponding to the locking bolts one by one, and the feeder cabinet 1 is provided with a slide rail slidably connected to the decorative panel 11. The operator can flexibly install the decorative panel 11 by pulling and pulling the decorative panel 11 along the mounting rail 2. When the decorative panel 11 needs to be removed, the locking bolt is removed to pull and pull the decorative panel 11, which effectively enables the operator to install and remove the decorative panel 11 of the feeder cabinet 1.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
