Description

[0001] The invention relates to the technical field of electrical cabinets, and in particular to a modular quick-assembly electrical cabinet and an assembling method thereof. Background Art

[0002] Manufacturers usually customize electrical cabinets according to the specific needs of customers. As a key component of the power distribution system, air switches (circuit breakers) have various specifications due to different customers, including current capacity, number of poles and brand preference. In most cases, manufacturers have completed the installation of fixed components such as guide rails, terminal blocks, busbars and necessary wiring work before leaving the factory. However, due to the large size and heavy weight of air switches, if pre-installed, they may become loose or damaged due to vibration during transportation. Separate transportation to the site for installation can ensure higher safety, and separate packaging of air switches can significantly reduce transportation risks.

[0003] Users often need to assemble the air switches themselves when they receive the distribution cabinets, but this process is quite cumbersome because each air switch requires at least four bolts to fix it to the guide rails, and the staff need to repeatedly perform the tightening operation. In addition, there are usually multiple rows of air switches to be installed, and the number is large. The entire assembly operation is time-consuming and laborious, and it is difficult to achieve the goal of quick installation. Summary of the invention

Transverse guide rails 3 are bolted between the vertical brackets 2 on both sides. A partition 5 is bolted to the top of the cabinet body 1. A storage box 6 is bolted to the inside of the cabinet body 1 and located above the partition 5. The storage box 6 is made of plastic and is relatively light when not filled with water. A liquid inlet is provided on the top of the storage box 6 through a hose. 17, the inner wall of the liquid inlet 17 is threadedly connected with a sealing cover 18, the liquid inlet 17 penetrates to the top of the cabinet 1, the sealing cover 18 can be removed from the surface of the liquid inlet 17 by rotating, and then water can be added to the inside of the storage box 6 through the liquid inlet 17 to increase the weight of the storage box 6, and the liquid inlet 17 and the storage box 6 are connected to each other through a hose, which can keep the connection between them during the downward movement of the storage box 6, the surface of the partition 5 is bolted with a vertical cylinder 7, and the inner wall of the vertical cylinder 7 is slidably connected with The first piston 8 has a first movable rod 9 bolted to the top of the first piston 8, and the first movable rod 9 is slidably connected to the inlet and outlet at the top of the vertical cylinder 7. The inlet and outlet at this location can be designed as an oil seal similar to a hydraulic cylinder. The top of the first movable rod 9 is bolted to the surface of the bottom of the storage box 6. The bottom of the vertical cylinder 7 is connected to a first pipeline 10, which is composed of a long tube, a three-way interface and two short tubes. The other end of the first pipeline 10 away from the vertical cylinder 7 is connected to a box body 11, and the box body 11 is provided with two groups of transverse guides up and down. A fixing frame 13 is bolted to the surface of the rail 3. The fixing frame 13 consists of a cross-shaped frame, four circular sleeves and a connecting plate. The box body 11 and the connecting plate extending from the fixing frame 13 are bolted and fixed to each other. Transverse tubes 14 are fixed to the four sides of the surface of the fixing frame 13. A second pipeline 12 is provided at one end of the transverse tube 14, and the end of the second pipeline 12 away from the transverse tube 14 is communicated with the box body 11. The second pipeline 12 consists of a section of a pipeline connected to the box body 11, a three-way interface and four pipelines respectively connected to four groups of transverse tubes 14.

[0020] The synchronous fixing mechanism 15 includes an inner cylinder 151, a second piston 152 and a second movable rod 153. The inner cylinder 151 is bolted to the inside of the transverse cylinder 14. The inner cylinder 151 and the second pipeline 12 are communicated with each other. The second piston 152 and the second movable rod 153 are bolted to each other. A circular plate 154 is bolted to the surface of the second movable rod 153 and is located on the outside of the inner cylinder 151. The circular plate 154 is slidably connected to the inner wall of the transverse cylinder 14. A movable block 156 is bolted to one end of the second movable rod 153 away from the inner cylinder 151. A through groove 157 is provided on the surface of the movable block 156, and the inner wall of the through groove 157 is inclined. The through groove 157 is inclined and close to the center of the movable block 156. A cylinder 159 is slidably connected to the inner wall of the through groove 157. A positioning block 158 is welded on the surface of the cylinder 159. The number of cylinders 159 is two groups and divided into The lateral cylinder 14 is welded on both sides of the positioning block 158. The number of the positioning blocks 158 is two groups and they are arranged up and down. The upper and lower sides of the lateral cylinder 14 are provided with grooves for the positioning blocks 158 to slide. A ring 155 is also bolted to one side of the inner wall of the lateral cylinder 14. The surface of the ring 155 close to the inner cylinder body 151 is fixed with a first spring 1510, and the other end of the first spring 1510 is in contact with the circular plate 154. Under the action of the first spring 1510, the circular plate 154 and the first movable rod 9 are subjected to a force toward the inner cylinder body 151, which causes the second movable rod 153 to push the circular plate 154 to move toward the inner cylinder body 151, and the second movable rod 153 drives the movable block 156 to move, so that the cylinder 159 changes its position on the inner wall of the through groove 157, thereby retracting the positioning block 158 to the inside of the lateral cylinder 14. This is in a state without hydraulic pressure.

[0021] The single-item control mechanism 16 includes a piston plate 161, a through hole 162, a third movable rod 163 and a positioning assembly. The piston plate 161 is L-shaped and is slidably connected to the inner wall of the box body 11. The through hole 162 is opened on the surface of the piston plate 161. The third movable rod 163 and the top of the piston plate 161 are bolted to each other. The third movable rod 163 is slidably connected to the inlet and outlet at the top of the box body 11. The top of the third movable rod 163 is hinged with a connecting rod 164. A transverse groove is designed at the hinge between the connecting rod 164 and the third movable rod 163 for connection with each other. The other end of the connecting rod 164 is bolted with a sleeve 165. A vertical rod 166 is also bolted to one side of the box body 11, and the connecting rod 164 is rotatably connected to the surface of the vertical rod 166. The positioning assembly fixes the sleeve 165 so that the through hole 162 on the surface of the piston plate 161 corresponds to one end of the first pipeline 10 close to the box body 11, so that the oil circuit is connected.

[0022] During the production process, it is necessary to inject hydraulic oil into the equipment in advance, so that the lower part of the vertical cylinder 7, the first pipeline 10, the second pipeline 12, the box body 11 are located below the piston plate 161, and the inner cylinder 151 is located on the side away from the second movable rod 153. There is hydraulic oil in these structures. During the hydraulic oil filling process, the amount of filling should be paid attention to. It should not be too much to cause the second movable rod 153 and the second piston 152 to overcome the force from the first spring 1510 and move significantly. The storage box 6 above is made of lightweight plastic, so that before water is injected, the weight will not overcome the elastic force from multiple first springs 1510, causing the first piston 8 and the first movable rod 9 to drop significantly, so that the positioning block 158 is inside the surface groove of the horizontal cylinder 14 (such as Fig. 9 As shown, it is the position of the positioning block 158 before the storage tank 6 is filled with water), and the positioning assembly fixes the sleeve 165, and the piston plate 161 will not be lifted at will due to the filling of hydraulic oil.

[0023] It should be noted that during the hydraulic oil filling process, the second movable rod 153 may extend and move slightly, which will cause the positioning block 158 to move slightly. It is only necessary to ensure that the positioning block 158 is always in the groove on the surface of the transverse cylinder 14 after the hydraulic oil is filled.

[0024] Before assembly, the reaction force of the first spring 1510 acts on the hydraulic oil inside the inner cylinder 151 through the circular plate 154, the second movable rod 153, and the second piston 152, and acts on the surface of the first piston 8 through the second pipeline 12, the box body 11, the first pipeline 10, and the hydraulic oil inside the vertical cylinder 7, so that the first piston 8 stays at a slightly higher position inside the vertical cylinder 7, so that the storage box 6, the first movable rod 9 and the first piston 8 will not be affected by gravity and continue to descend, maintaining the balance between the upper and lower parts. The hydraulic system relies on the incompressibility of liquid (hydraulic oil) to transmit force and movement. The principle of this process is the effect of oil transmission.

[0025] It should be noted that the total length of the first pipeline 10 and the second pipeline 12, plus the internal space below the vertical cylinder 7, the inner cylinder 151, and the box body 11, does not exceed 3 meters, and the purpose of these structural combinations is not for precise mechanical instrument operations, and the oil transmission loss can be ignored.

[0026] During the assembly process, the cabinet door, internal guide rails, some wiring terminals, busbars, and necessary wiring are installed by the manufacturer itself. The user only needs to install the air switch body 4 inside the electrical cabinet according to his own needs to complete the assembly of the air switch. The user needs to align the holes of the bolts reserved on the surface of the air switch body 4 with the surface of the transverse tube 14. The transverse tubes 14 in a group of four enter the reserved holes on the surface of the air switch body 4, and hang the air switch body 4 on the surface of the transverse guide rail 3. Then, all the air switch bodies 4 are hung according to the above steps, and other air switch bodies 4 are hung. Then, the top of the cabinet 1, that is, the sealing cover 18 on the top of the liquid inlet 17, is opened, and water is injected into the liquid inlet 17 through a hose connected to tap water. At this time, the weight inside the storage box 6 gradually increases, overcoming the force from the first spring 1510 to the first piston 8 and the first movable rod 9 through the oil transmission, so that the first piston 8, the first movable rod 9, and the storage box 6 are lowered. The upper part of the cabinet 1 is also bolted with a slide rail 1 9. The back of the storage box 6 is bolted with a slider 22 that is slidably connected to the surface of the slide rail 19. The slider 22 can be made of lightweight aluminum alloy and will not significantly increase the weight of the storage box 6 when it is unloaded. Then, multiple groups of first pistons 8 and first movable rods 9 drop due to the increased weight of the storage box 6. Each group of synchronous fixing mechanisms 15 simultaneously drives the internal hydraulic oil to flow through the first pipeline 10, the space below the inside of the box body 11, the second pipeline 12, and the inside of the inner cylinder 151, and pushes the second piston 152 and the second movable rod 153 to move, so that the first spring 1510 is gradually compressed and drives the movable block 156 to move. The position of the cylinder 159 in the through groove 157 changes, allowing the positioning block 158 to extend from the inside of the transverse cylinder 14. The positioning block 158 covers the side of the hole on the surface of the air switch body 4 away from the transverse guide rail 3, thereby fixing the air switch body 4 on the surface of the transverse guide rail 3, and can simultaneously fix multiple air switch bodies 4 without tightening the bolts one by one, which is more efficient and realizes modular assembly.

[0027] If it is necessary to replace the air switch body 4 on a large scale, for example, when the power of the electrical equipment increases significantly and the rated current of the original air switch cannot meet the demand or when the circuit system is replaced and upgraded, it is necessary to replace most of the air switch bodies 4 inside the electrical cabinet; a discharge pipe 20 is also connected to one side of the bottom of the storage box 6, and a valve 21 is installed on the surface of the discharge pipe 20. In actual use, a small door (such as Figure 1As shown in the figure, when it is necessary to remove all the air switch bodies 4 simultaneously, by opening the side door of the cabinet 1, placing a container at the head end of the discharge pipe 20 or connecting a hose leading to the sewer, and then opening the valve 21, the water discharge operation can be implemented, the weight inside the storage box 6 is reduced, and the hydraulic oil inside the oil pipeline is also reduced by the downward pressure from the storage box 6. The reaction force of the first spring 1510 pushes the circular plate 154, the first movable rod 9 and the first piston 8 to move again, thereby moving the movable block 156, changing the position of the cylinder 159 in the through groove 157, and allowing the positioning block 158 to re-enter the groove on the surface of the transverse cylinder 14, thereby releasing the fixation of the air switch body 4, and all the air switch bodies 4, thereby realizing the modular rapid installation and disassembly of the air switch body 4.

[0028] In actual use, it is rare to encounter large-scale disassembly and replacement of the air switch body 4. Sometimes, due to the damage of a single air switch body 4, only a single air switch body 4 needs to be disassembled and replaced. Therefore, a single control mechanism 16 and an attached positioning component are set. The positioning component includes an arc rod 167 and a positioning hole 168. One end of the arc rod 167 is bolted to the box body 11. The positioning hole 168 is opened above the surface of the arc rod 167. The arc rod 167 passes through the sleeve 165 and is slidably connected to the penetration point. A groove is also opened on the surface of the sleeve 165 for the arc rod 167 to pass through. A button 169 is slidably connected to the inner wall of the sleeve 165 away from the connecting rod 164. The button 169 is located on the inner wall of the sleeve 165 and is bolted to the fixing rod 161 0, the end of the fixing rod 1610 away from the button 169 is bolted with a positioning protrusion 1611, the positioning protrusion 1611 is composed of a round block and a protrusion, and the protrusion on the surface of the positioning protrusion 1611 cooperates with the positioning hole 168. A second spring 1612 is also fixed deep inside the sleeve 165, and the other end of the second spring 1612 is in contact with the positioning protrusion 1611. The second spring 1612 gives the positioning protrusion 1611 a force toward the button 169, which makes the protrusion of the positioning protrusion 1611 enter the interior of the positioning hole 168, thereby positioning the sleeve 165, the connecting rod 164 and even the third movable rod 163 and the piston plate 161. In the process of assembling or disassembling multiple air switch bodies 4, the piston plate 16 1 is aligned with one end of the first pipeline 10 close to the box body 11 to maintain normal oil transmission. If one wants to disassemble a certain air switch body 4 individually, the button 169 in the single-item control mechanism 16 corresponding to the air switch body 4 can be pressed at this time, so that the button 169 goes deep into the sleeve 165, and then the positioning protrusion 1611 is driven by the fixing rod 1610 to move, so that the protruding part of the positioning protrusion 1611 is separated from the inside of the positioning hole 168, and the fixing of the sleeve 165 and the connecting rod 164 is released. Then, the sleeve 165 is pressed down, and a lever-like principle is adopted to drive one end of the connecting rod 164 to rise, thereby driving the third movable rod 163 and the piston plate 161 to rise, so that the through hole 162 on the surface of the piston plate 161 is no longer aligned with the first The pipeline 10 is connected, and at the same time, the space below the piston plate 161 inside the box body 11 increases, and the internal hydraulic oil pressure drops suddenly, so that the first spring 1510 pushes the first circular plate 154 and the first movable rod 9 to move in the direction of the moving inner cylinder 151 (the moving distance is limited by the length of the through groove 157, and the positioning block 158 can only move in the vertical direction), so that the movable block 156 moves, and the positioning block 158 re-enters the groove on the surface of the horizontal cylinder 14, so that the fixation of the single air switch body 4 is released, and then replaced with a new one, and then the button 169 is pressed again to move the sleeve 165 to rotate upward, so that the protrusion on the surface of the positioning protrusion 1611 is realigned with the positioning hole 168, and then the button 169 is released. Under the action of the second spring 1612,The protrusion on the surface of the positioning protrusion 1611 re-enters the interior of the positioning hole 168, completing the fixing of the sleeve 165, the connecting rod 164 and the piston plate 161, allowing the first pipeline 10 to be re-connected with the through hole 162, the hydraulic transmission to be re-connected, and the first piston 8 to be re-pressurized, so that the positioning block 158 is re-extended from the groove on the surface of the transverse cylinder 14, and the newly replaced single air switch body 4 is fixed. In this way, the electrical cabinet can not only fix or remove multiple air switches synchronously on a large scale, but also perform single operations.

[0029] A method for assembling a modular and fast-assembly electrical cabinet comprises the following steps: Step ①, align the four air switches on the surface of the air switch body 4 with the four transverse tubes 14 of the same group, and suspend them through the transverse tubes 14; Step ②, open the sealing cover 18, supply water to the storage box 6 through the liquid inlet 17, increase the weight of the storage box 6 to implement weight pressing, so that the storage box 6 overcomes the reaction force from the multiple first springs 1510, and drives the first movable rod 9 and the first piston 8 to descend; Step ③, the first piston 8 descends to squeeze the hydraulic oil below the vertical cylinder 7, and uses the oil transmission effect of the first pipeline 10, the box body 11, the second pipeline 12 and the inner cylinder body 151 to push the second piston 152 and the second movable rod 153 to move; Step ④: The second movable rod 153 pushes the movable block 156 to move, changing the position of the cylinder 159 on the inner wall of the through groove 157, so that the positioning block 158 extends to the outside of the surface groove of the transverse tube 14, fixes the air switch body 4, and completes the assembly.
