Description

Technical Field

[0001] This application relates to the technical field of switchgear, and in particular to a low-voltage withdrawable switchgear assembly. Background Technology

[0002] Low-voltage withdrawable switchgear, also known as switch cabinets, is used for low-voltage power receiving in industries such as power plants, substations, industrial and mining enterprises, civil buildings, and municipal facilities.

[0003] In related technologies, low-voltage switchgear includes a switch box, which contains a busbar compartment, a fuse compartment, and multiple control units. Each control unit has a drawer installed on it, and the gap between two drawers is for placing the control unit. The drawers are slidably connected to the switch box. When it is necessary to inspect the wiring inside the switch box, the drawer needs to be opened. When the drawer is opened, the external load is de-energized, making it convenient for staff to carry out maintenance.

[0004] In the aforementioned technologies, since the distance between the two drawers cannot be adjusted, when a large control unit needs to be installed inside the drawer, the distance between the two drawers cannot meet the installation requirements. Therefore, it is necessary to replace the corresponding switch box to meet the installation requirements, which makes it inconvenient to use. Summary of the Invention

[0005] In order to adjust the position of the drawer installed on the switch box, this application provides a low-voltage withdrawable complete low-voltage switchgear.

[0006] The low-voltage withdrawable switchgear provided in this application adopts the following technical solution:

[0007] A low-voltage withdrawable switchgear includes a switch housing and multiple mounting brackets disposed within the switch housing. Each mounting bracket has a drawer slidably connected to it for mounting a control unit. The switch housing is provided with an adjustment assembly, which includes a screw rotating on the switch housing and multiple rotating sleeves threadedly connected to the screw. The rotating sleeves rotate on the mounting brackets. A fixing rod is slidably connected to the mounting brackets. A fixing groove is formed on the rotating sleeve. When the fixing rod moves to the fixing groove, the rotating sleeve is fixed on the mounting bracket.

[0008] By adopting the above technical solution, when a large control unit needs to be installed, the fixed rod on the mounting bracket that needs to be moved is pushed into the fixed slot. At this time, the rotating sleeve is fixed on the mounting bracket. Then, the screw is rotated, and the screw drives the rotating sleeve to move along its own axis, thereby adjusting the distance between two adjacent drawers. When the position of all drawers needs to be adjusted, all the fixed rods are pushed into the fixed slot, and then the screw is rotated, which can drive all the drawers to move, thereby achieving the purpose of conveniently adjusting the drawers.

[0009] Optionally, a locking rod is slidably connected to the mounting bracket, and multiple locking grooves are provided on the inner wall of the switch box. The multiple locking grooves are spaced apart along the axial direction of the screw. The mounting bracket is provided with a drive assembly for pushing the locking rod into the locking groove. When the locking rod moves into the locking groove, the position of the mounting bracket is fixed.

[0010] By adopting the above technical solution, after the positions of the drawer and the mounting bracket are adjusted, the drive assembly moves the locking rod into the locking groove, thereby improving the stability of the mounting bracket and the drawer when they are fixed to the switch box.

[0011] Optionally, the drive assembly includes a rotating shaft that rotates on the mounting bracket and a cam fixed on the rotating shaft, the surface of the cam abutting against the end of the locking rod away from the locking groove.

[0012] By adopting the above technical solution, when a fixed mounting bracket is required, the rotating shaft is rotated, causing the rotating shaft to drive the cam to rotate, thereby facilitating the movement of the fixing rod into the fixing groove.

[0013] Optionally, a return spring is fitted on the locking rod, with one end of the return spring fixed to the locking rod and the other end fixed to the mounting bracket.

[0014] By adopting the above technical solution, when it is necessary to adjust the position of the mounting bracket and the drawer, the rotating shaft is rotated in the opposite direction, causing the rotating shaft to drive the cam to disengage from the locking rod. Then, under the action of the return spring, the locking rod is pushed to disengage from the locking groove, thereby facilitating the adjustment of the mounting bracket position.

[0015] Optionally, the mounting bracket is provided with a control component for driving the rotating shaft to rotate. The control component includes a driving bevel gear, a driven bevel gear meshing with the driving bevel gear, and a control rod fixed on the driving bevel gear. The control rod is rotatably connected to the mounting bracket, and the driven bevel gear is fixed on the rotating shaft.

[0016] By adopting the above technical solution, rotating the control lever causes the rotating shaft to rotate, the cam disengages from the locking lever, and under the action of the return spring, pushes the locking lever out of the locking groove. Rotating the control lever in the opposite direction causes the rotating shaft to drive the cam to rotate in the opposite direction, thereby facilitating the movement of the locking lever into the locking groove. Finally, the positions of the mounting bracket and drawer are fixed.

[0017] Optionally, the end of the fixing rod away from the rotating sleeve is inserted into the control rod and threadedly connected to the control rod. When the locking rod is inserted into the locking groove, the fixing rod disengages from the fixing groove.

[0018] By adopting the above technical solution, when the drawer and mounting bracket need to be adjusted, rotating the control lever causes the control lever to drive the rotating shaft to rotate, the cam disengages from the locking lever, and under the action of the return spring, pushes the locking lever out of the locking groove. Since the fixed rod and the control lever are threadedly connected, and the fixed rod is slidably connected to the mounting bracket, at this time, the rotation of the control lever drives the fixed rod to rotate into the fixed groove. Finally, rotating the screw can adjust the position of the mounting bracket and the drawer, making it more convenient to use.

[0019] Optionally, the mounting bracket is provided with a slide groove, which is opened along a direction perpendicular to the screw axis. A slider is engaged in the slide groove and the slider is fixed to the side of the drawer. A limit groove is opened at the end of the slide groove near the control rod. The limit groove is opened on the bottom wall of the slide groove and communicates with the slide groove. An opening communicating with the outside is provided at the end of the slide groove away from the bottom wall.

[0020] By adopting the above technical solution, when the drawer is pulled out from the mounting bracket, the slider slides in the slide groove. When the slider and the limit groove correspond, the slider enters the limit groove, which can prevent the drawer from suddenly detaching from the mounting bracket when the drawer is pulled out. When it is necessary to remove the drawer from the mounting bracket, push the drawer away from the mounting bracket, and the slider will detach from the opening of the limit groove.

[0021] Optionally, the switch housing is provided with a push assembly for simultaneously rotating all control levers. The push assembly includes a gear fixed coaxially with the control levers and a rack sliding on the switch housing. The rack is slidably connected to the switch housing.

[0022] By adopting the above technical solution, when all the control levers on the switch box need to be rotated, the rack is pushed to move closer to the gear, so that the rack and gear mesh. Then the rack is pushed to move along the length of the screw, thereby driving the gear to rotate, which in turn drives the control lever to rotate, making it more convenient to use.

[0023] Optionally, the control rod is provided with a control block, and the mounting bracket is provided with a first control slot and a second control slot. When the control block rotates into the first control slot, the locking rod disengages from the locking slot. When the control block rotates into the second control slot, the locking rod is engaged in the locking slot.

[0024] By adopting the above technical solution, when it is necessary to move the mounting bracket and drawer, the control lever is rotated, causing the control lever to drive the control block from the second control slot to the first control slot, and the cam and locking rod disengage. Then, it is convenient for the user to observe the rotation position and angle of the control lever, and to know whether the locking rod has disengaged from the locking slot.

[0025] Optionally, the fixing groove is provided in multiple ways, and the multiple fixing grooves are evenly spaced along the circumference of the rotating sleeve.

[0026] By adopting the above technical solution, multiple fixing slots are set, which makes it convenient for the fixing rod to still be inserted into the fixing slot when the rotating sleeve rotates with the screw. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a low-voltage withdrawable complete low-voltage switchgear. (Refer to...) Figure 1A low-voltage withdrawable switchgear includes a switch box 01, which is vertically arranged. A first opening is provided on one side of the switch box 01. A cabinet door 02 is rotatably connected to the switch box 01, and the cabinet door 02 is used to seal the switch box 01. Multiple mounting brackets 03 are installed inside the switch box 01, spaced apart along the height direction of the switch box 01. Each mounting bracket 03 is equipped with a drawer 04, which is used to install a control unit. An adjusting component 1 is also installed inside the switch box 01 to adjust the position of the drawer 04, thereby facilitating the installation of control units of different heights in the drawer 04. The drawer 04 is slidably connected to the mounting bracket 03. When the control unit in the drawer 04 needs maintenance or inspection, the drawer 04 is pulled out, causing it to detach from the switch box 01. At this time, the load and internal fuse are disconnected, facilitating personnel to inspect the inside of the drawer 04.

[0036] Reference Figure 1 and Figure 2 The mounting bracket 03 has a horizontally oriented sliding groove 05, within which a slider 06 is slidably connected. The mounting bracket 03 also has a vertically oriented limiting groove 07. The limiting groove 07 is closed at one end near the ground, and open at the other end 08, which communicates with the outside. The limiting groove 07 and the sliding groove 05 are connected at the ends near the cabinet door 02. When the drawer 04 is pulled, the drawer 04 moves the slider 06 within the sliding groove 05. When the slider 06 aligns with the limiting block, under the influence of gravity, the slider... Block 06 enters the limiting groove 07, thus preventing drawer 04 from falling directly off the mounting bracket 03 when it is pulled, and also preventing drawer 04 from moving in the slide 05. At this time, the control unit inside drawer 04 can be inspected on the mounting bracket 03. Then, when it is necessary to remove drawer 04 from the mounting bracket 03, push drawer 04 away from the ground. The slider 06 moves from the end of the limiting groove 07 near the ground to the opening 08, so that the slider 06 can be removed from the limiting groove 07, and then the drawer 04 can be removed from the mounting bracket 03 for inspection of the control unit.

[0037] Reference Figure 2 and Figure 3 Each mounting bracket 03 is provided with an adjustment component 1. The structure and shape of each adjustment component 1 are the same. In this embodiment, only one set of adjustment components 1 will be described in detail. The adjustment component 1 includes a screw 11 and a rotating sleeve 12. The screw 11 is set vertically, and both ends of the screw 11 are rotatably connected to the switch box 01. The rotating sleeve 12 is threadedly connected to the screw 11 and is rotatably connected to the mounting bracket 03. When the screw 11 is rotated, since the rotating sleeve 12 is rotatably connected to the mounting bracket 03, the screw 11 will not drive the mounting bracket 03 and the drawer 04 to move.

[0038] Reference Figure 3 and Figure 4 A fixed rod 2 is slidably connected to the mounting bracket 03. The fixed rod 2 is horizontally positioned and slides towards or away from the rotating sleeve 12. Multiple fixing slots 21 are formed on the rotating sleeve 12, evenly spaced along its circumference. Pushing the fixed rod 2 moves it to a fixing slot 21, fixing the position of the rotating sleeve 12. Thus, rotating the screw 11 allows the mounting bracket 03 and drawer 04 to move along the length of the screw 11. To facilitate the movement of the fixed rod 2 into the fixing slot 21, the end of the fixed rod 2 near the fixing slot 21 is chamfered.

[0039] Reference Figure 1 , Figure 3 and Figure 4 The mounting bracket 03 includes two sliding rods 031 and one connecting rod 032. The sliding rods 031 are welded to both ends of the connecting rod 032, and the sliding rods 031 and the connecting rod 032 are arranged vertically. The side of the sliding rod 031 away from the connecting rod 032 abuts against the inner wall of the switch box 01. In this embodiment, the number of mounting brackets 03 is set to four, and the number of drawers 04 is also set to four, with each drawer 04 corresponding to a mounting bracket 03. The mounting brackets 03 are arranged horizontally, and each sliding rod 031 near the adjusting component 1 is provided with a locking rod 22. The locking rod 22 is arranged horizontally, and multiple locking grooves 23 are opened on the inner wall of the switch box 01. When the locking rod 22 is inserted into the locking groove 23, the locking rod 22 can fix the mounting bracket 03 on the switch box 01. Multiple locking grooves 23 are provided, and the multiple locking grooves 23 are evenly spaced along the axial direction of the screw 11 on the inner wall of the switch box 01, which can fix the mounting brackets 03 at different positions. To improve the fixing effect of the mounting bracket 03, each mounting bracket 03 is provided with multiple locking rods 22. The multiple locking rods 22 are evenly spaced along the length direction of the slide groove 05. In this embodiment, each mounting bracket 03 is provided with three locking rods 22, and the three locking rods 22 correspond to three locking grooves 23.

[0040] Reference Figure 1 , Figure 3 and Figure 4The mounting bracket 03 is equipped with a drive assembly 3, which is used to drive the locking rod 22 to move into the locking groove 23. The drive assembly 3 includes a rotating shaft 31 and a cam 32. The two ends of the rotating shaft 31 are rotatably connected to the mounting bracket 03. The cam 32 is welded to the rotating shaft 31. Three cams 32 are welded on each rotating shaft 31. The three cams 32 correspond one-to-one with the three locking rods 22 that slide on the mounting bracket 03. The surface of the cam 32 abuts against the end of the locking rod 22 away from the locking groove 23. After the position of the mounting bracket 03 and the drawer 04 is adjusted, the rotating shaft 31 is rotated, and the cam 32 pushes the locking rod 22 to move into the locking groove 23, thereby fixing the adjusted mounting bracket 03 and drawer 04.

[0041] Reference Figure 1 , Figure 3 and Figure 4 To facilitate the disengagement of the locking rod 22 from the locking groove 23, a return spring 24 is fitted onto the locking rod 22. One end of the return spring 24 is welded to the locking rod 22, and the other end is welded to the mounting bracket 03. When the cam 32 pushes the locking rod 22 to the locking groove 23, the return spring 24 is compressed. When it is necessary to move the mounting bracket 03 and the drawer 04, the rotating shaft 31 is rotated in the opposite direction. The rotating shaft 31 drives the cam 32 to rotate in the opposite direction. When the cam 32 disengages from the locking rod 22, under the action of the return spring 24, it pushes the locking rod 22 to automatically disengage from the locking groove 23, thus making it more convenient to drive the locking rod 22 to disengage from the locking groove 23.

[0042] Reference Figure 1 , Figure 3 and Figure 4 A control component 4 is provided on the mounting bracket 03. The control component 4 is used to drive the rotating shaft 31 to rotate. The control component 4 includes a driving bevel gear 41, a driven bevel gear 42 and a control rod 43. The driving bevel gear 41 and the control rod 43 are fixed coaxially. The driving bevel gear 41 and the driven bevel gear 42 are meshed. At the same time, the driven bevel gear 42 and the rotating shaft 31 are coaxially arranged. The control rod 43 is rotatably connected to the mounting bracket 03. The axis of the control rod 43 is perpendicular to the axis of the screw 11. The control rod 43 and the locking rod 22 are parallel. Rotating the control rod 43 causes the control rod 43 to drive the driving bevel gear 41 to rotate. Under the action of the driven bevel gear 42, the rotating shaft 31 is driven to rotate, thereby facilitating the movement of the locking rod 22 into the locking groove 23.

[0043] Reference Figure 1 , Figure 3 and Figure 4The end of the fixing rod 2 away from the fixing groove 21 is inserted into the control rod 43, and the fixing rod 2 and the control rod 43 are threaded together. When the control rod 43 is rotated, the fixing rod 2 slides on the mounting bracket 03, thereby driving the fixing rod 2 to move along the length of the control rod 43. When the control rod 43 is rotated, causing the control rod 43 to drive the locking rod 22 to move into the locking groove 23, the fixing rod 2 disengages from the fixing groove 21 on the rotating sleeve 12. At this time, the rotating screw 11 cannot adjust the position of the mounting bracket 03, and the mounting bracket 03 is fixed under the action of the locking rod 22. When the control rod 43 is rotated in the opposite direction, the fixing rod 2 moves into the fixing groove 21, and then the locking rod 22 disengages from the locking groove 23. At this time, the rotating screw 11 can drive the mounting bracket 03 to move, thereby facilitating the adjustment of the position of the mounting bracket 03.

[0044] Reference Figure 2 and Figure 5 To facilitate user observation of the rotation angle of the control lever 43, a control block 5 is welded onto the control lever 43. The end of the control block 5 away from the control lever 43 extends out of the mounting bracket 03. At the same time, a first control groove 51 and a second control groove 52 are provided on the mounting bracket 03. The second control groove 52 is located below the first control groove 51. When the end of the control block 5 away from the control lever 43 rotates to the first control groove 51, the locking rod 22 disengages from the locking groove 23, and the fixing rod 2 is inserted into the fixing groove 21. When the control block 5 rotates to the second control groove 52, the locking rod 22 is inserted into the locking groove 23, and the fixing rod 2 disengages from the fixing groove 21, thus making it easy to know whether the locking rod 22 is engaged in the locking groove 23.

[0045] Reference Figure 2 and Figure 3 A push assembly 6 is provided on the switch housing 01. The push assembly 6 is used to push the four control levers 43 on the switch housing 01 to rotate simultaneously. The push assembly 6 includes multiple gears 61 and a rack 62. The end of each control lever 43 away from the fixed rod 2 is welded and coaxially fixed with the gear 61. The rack 62 is slidably connected to the switch housing 01. The rack 62 can slide along the direction of movement of the fixed rod 2, and can also slide along the axis of the screw 11. When the rack 62 slides along the axis of the screw 11, multiple gears 61 mesh with the rack 62 simultaneously. Pushing the rack 62 to move can drive the gears 61 to rotate, thereby facilitating the rotation of the control levers 43.

[0046] Reference Figure 1 and Figure 6A movable groove 7 is provided on the switch housing 01. The movable groove 7 includes a first horizontal part 71, a second horizontal part 72, and a first vertical part 73. The first horizontal part is located below the second horizontal part 72. The first vertical part 73 is vertically arranged and communicates with the ends of the first horizontal part 71 and the second horizontal part 72 near the fixed rod 2, respectively. The first horizontal part 71, the first vertical part 73, and the second horizontal part 72 are C-shaped. A push block 53 is slidably connected in the movable groove 7. The push block 53 is welded to the rack 62. In the initial state, the push block 53 is located at the end of the first horizontal part 71 away from the second vertical part. At this time, the rack 62 cannot move. When it is necessary to drive the control lever 43 to rotate, the push block 53 moves to the connection between the first horizontal part 71 and the first vertical part 73. At this time, the rack 62 and the gear 61 mesh, and then push... The push block 53 moves within the first vertical portion 73. When the push block 53 moves to the point where the first vertical portion 73 and the second horizontal portion 72 connect, the cam 32 completely disengages from the locking rod 22, and the control block 5 rotates into the first control groove 51. At this time, the locking rod 22 disengages from the locking groove 23. To prevent the rack 62 from continuing to drive the gear 61 to rotate, the push block 53 is pushed into the second horizontal portion 72, and the rack 62 cannot move within the first vertical portion 73. To facilitate the movement of the rack 62 near the second vertical portion in the second horizontal portion 72 without separation between the rack 62 and the gear 61, in this embodiment, the thickness of the gear 61 is less than the width of the rack 62. When the push block 53 and the rack 62 move in the opposite direction, all the locking rods 22 are driven into the locking groove 23, making it more convenient to drive all the locking rods 22 to move. In addition, when it is not necessary for all the locking rods 22 to move, the rack 62 and the gear 61 are separated, and the push block 53 is located within the first horizontal portion 71 or the second horizontal portion 72.

[0047] Reference Figure 1 A rotating assembly is provided on the switch housing 01. The rotating assembly is used to drive the screw 11 to rotate. The rotating assembly includes a worm wheel and a worm. The worm wheel is fixed on the screw 11. The worm and the worm wheel mesh. The worm is rotatably connected to the switch housing 01, and one end of the worm extends out of the switch housing 01. By rotating the worm, the worm wheel and the screw 11 are driven to rotate, which makes it more convenient to use.

[0048] The implementation principle of a low-voltage withdrawable complete low-voltage switchgear according to the embodiment of this application is as follows: When installing the control unit, the distance between drawers 04 can be adjusted according to the size of the control unit. The control lever 43 is rotated, which drives the active bevel gear 41 to rotate. Under the action of the driven bevel gear 42, the rotating shaft 31 and the cam 32 are rotated, causing the cam 32 to disengage from the locking lever 22. Under the action of the return spring 24, the locking lever 22 is pushed to disengage from the locking groove 23. At the same time as the control lever 43 rotates, the fixing lever 2 is pushed to rotate into the fixing groove 21. The rotating sleeve 12 is fixed on the mounting bracket 03. Then, the screw 11 is rotated, which drives the rotating sleeve 12 and the mounting bracket 03 to move, thereby facilitating the adjustment of the position of the mounting bracket 03 and the drawers 04.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
