Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power equipment, and in particular to a power control cabinet. BACKGROUND

[0002] The power control cabinet is a facility for centralized and effective management of power distribution to ensure the safe and stable operation of the power grid and reliable external power supply, and has the characteristics of small size, simple installation steps, unrestricted installation site, stable and reliable operation, and high space utilization, and is widely used in power grid systems.

[0003] During use of the power control cabinet, a large number of power distribution equipment (such as switch equipment, measuring instruments, protective electrical appliances, and auxiliary equipment) are assembled in a closed or semi-closed metal cabinet. When the power distribution equipment is tripped or requires daily maintenance, an operator needs to carry auxiliary tools to maintain the interior of the power control cabinet. However, because the interior space of the power control cabinet is generally narrow, when the operator is repairing, the operator usually needs to stretch his arm into the narrow space inside the power control cabinet to operate. The interior of the control cabinet is often dark and obstructed by the cabinet body, so that the operator's arm is difficult to stretch, the repair process is inconvenient to operate, and the repair process takes a long time, affecting the normal use of the power distribution network and causing great economic losses. SUMMARY

[0004] The purpose of the present application is to provide a power control cabinet that can provide sufficient operating space for operators during daily maintenance or repair, reduce the difficulty of operating electrical equipment during repair, improve the efficiency of repair and maintenance, and effectively reduce economic losses caused by repair of the power distribution network.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0051] Example 1

[0052] This embodiment provides a power control cabinet for housing electrical equipment such as switching devices, measuring instruments, protective electrical appliances, and auxiliary equipment. Figure 1 and Figure 2 As shown, the power control cabinet includes a cabinet body 1, a mounting mechanism 2, and a flip-up mechanism 3.

[0053] Specifically, the cabinet 1 includes a mounting cavity 11, and the cabinet 1 also has a first opening 12 communicating with the mounting cavity 11. For example, the cabinet 1 is rectangular, hollow inside to form the mounting cavity 11, and has an opening on one side, which is the first opening 12. The mounting mechanism 2 includes a mounting plate 21, which is disposed within the mounting cavity 11 and configured to mount electrical equipment 100. The mounting plate 21 can be inserted into the mounting cavity 11 of the cabinet 1 through the first opening 12, thereby providing safety protection for the electrical equipment 100 through the cabinet 1. The flip-up mechanism 3 includes a protective cover 31, which is connected to the cabinet 1 and can cover the first opening 12 to further protect the electrical equipment 100 within the mounting cavity 11. The protective cover 31 is connected to the mounting plate 21; rotating the protective cover 31 can move the mounting plate 21 from the mounting cavity 11 towards the first opening 12. When operators need to perform routine maintenance or repairs on the electrical equipment 100 within the housing, rotating the protective cover 31 will move the mounting plate 21 from the mounting cavity 11 to the first opening 12. In other words, the protective cover 31 and the mounting plate 21 are linked; when the protective cover 31 is rotated to open the first opening 12, the mounting plate 21 and the electrical equipment 100 on it move synchronously from the mounting cavity 11 to the first opening 12, providing ample operating space for operators, facilitating their work, reducing the operational difficulty of repairing the electrical equipment 100, improving maintenance efficiency, and effectively reducing economic losses caused by power distribution network maintenance.

[0054] For more details, please refer to [link / reference]. Figure 1 In this embodiment, a cabinet door 13 is also hinged to the cabinet body 1 to prevent external dust or rainwater from entering the installation cavity 11, so as to further protect the electrical equipment 100 inside the power control cabinet.

[0055] Optionally, such as Figures 3-5As shown, the flip-up mechanism 3 also includes a hinge block 32, a second hinge rod 33, and a guide post 34. A first groove is formed on the protective cover 31. The hinge block 32 is slidably connected to the first groove. The guide post 34 is connected to the cabinet 1 and is perpendicular to the rotation axis of the protective cover 31. One end of the second hinge rod 33 is hinged to the hinge block 32, and the other end is connected to the guide post 34. The hinge block 32 slides along the first groove, which can drive the other end of the second hinge rod 33 to move along the guide post 34. The other end of the second hinge rod 33 is also connected to the mounting plate 21. When the other end of the second hinge rod 33 moves along the guide post 34, it drives the mounting plate 21 to move. Specifically, in this embodiment, the protective cover 31 is rotatably connected to the top of the cabinet 1. Flipping the protective cover 31 downwards can seal the first opening 12. Two first sliding grooves are provided on one side of the protective cover 31 near the cabinet 1. Correspondingly, two hinge blocks 32, two second hinge rods 33, and two guide posts 34 are also provided. The two hinge blocks 32 can slide within the two first sliding grooves without dislodging from them. The two guide posts 34 are symmetrically connected to both sides of the cabinet 1 and extend along the height of the cabinet 1. The cooperation of the two sets of hinge blocks 32 and the second hinge rod 33 can make the force on the protective cover 31 more even when it rotates, avoiding jamming when the protective cover 31 rotates. For example, the first sliding groove is a rectangular groove, and the hinge block 32 is a cuboid slider. The size of the inner wall of the first sliding groove is adapted to the surface size of the hinge block 32.

[0056] More specifically, a guide and limiting structure is provided between the hinge block 32 and the first slide groove to guide and limit the sliding of the hinge block 32 within the first slide groove. The guide and limiting structure can be a combination of a guide groove and a guide block. A guide block protrudes from the side of the hinge block 32, and a guide groove is recessed in the side wall of the first slide groove. The guide block slides within the guide groove, preventing the hinge block 32 from dislodging from the first slide groove and guiding its sliding. Alternatively, a guide groove can be provided on the side of the hinge block 32, and a guide block can be provided on the first slide groove; both methods can guide and limit the sliding of the hinge block 32 within the first slide groove.

[0057] Optionally, see [link to relevant documentation] Figure 4 and Figure 5The flip-plate mechanism 3 also includes a second connecting member, a movable collar 35, and a pull block 36. The guide post 34 is hollow inside. The pull block 36 is disposed inside the guide post 34 and can move along the guide post 34. The movable collar 35 is sleeved on the outside of the guide post 34. A second limiting hole is formed on the side wall of the guide post 34 along its length direction. The second connecting member passes through the second limiting hole. Both ends of the second connecting member are respectively connected to the movable collar 35 and the pull block 36. The movable collar 35 is connected to the second hinge rod 33, and the pull block 36 is connected to the mounting plate 21. Specifically, in this embodiment, the movable collar 35 is hinged to the end of the second hinge rod 33 away from the hinge block 32, and the inner wall of the movable collar 35 is fixedly connected to the pull block 36 through the second connecting member. The pull block 36 is disposed inside the guide post 34 and can move along the length direction of the guide post 34. The pull block 36 is connected to the mounting plate 21, and the pull block 36 can pull the mounting plate 21 to move. For example, the movable collar 35 is annular, the pull block 36 is cuboid, the guide post 34 is hollow cylindrical, and the second limiting hole is a rectangular through hole opened along the length of the guide post 34. The second limiting hole is opened on the outer surface of the guide post 34, the inner wall size of the movable collar 35 is adapted to the outer surface size of the guide post 34, and the surface size of the pull block 36 is adapted to the inner wall size of the guide post 34. By setting the movable collar 35 to annular shape, it can be easily fitted onto the surface of the guide post 34, making the movable collar 35 move more smoothly along the guide post 34. Through the second limiting hole opened on the outer surface of the guide post 34, the pull block 36 can be driven to move along the second limiting hole when the movable collar 35 moves, thereby pulling the mounting plate 21.

[0058] Optionally, see [link to relevant documentation] Figure 4 The flip-plate mechanism 3 also includes a third connecting member 37. A through hole is provided on the bottom of the guide post 34 on the side opposite to the first opening 12. The third connecting member 37 passes through the through hole, and its two ends are respectively connected to the pull block 36 and the mounting plate 21. Specifically, in this embodiment, the third connecting member 37 is a steel rope. One end of the third connecting member 37 is fixedly connected to the pull block 36, and the other end extends out of the through hole, into the mounting cavity 11, and connects to the mounting plate 21. When the pull block 36 moves along the length of the guide post 34, the third connecting member 37 can pull the mounting plate 21 from the mounting cavity 11 towards the first opening 12.

[0059] Optionally, such as Figure 3 and Figure 4As shown, the mounting mechanism 2 also includes a support frame 22, a driving block 23, and a fourth connecting member. The support frame 22 is connected to the inner wall of the mounting cavity 11 and extends towards the first opening 12. The support frame 22 is connected to the bottom of the guide post 34. One end of the third connecting member 37 extends into the support frame 22. The driving block 23 is disposed within the support frame 22 and connected to the third connecting member 37. A third limiting hole is formed on the side wall of the support frame 22 along its length direction. The fourth connecting member passes through the third limiting hole, and both ends of the fourth connecting member are respectively connected to the driving block 23 and the mounting plate 21. Specifically, in this embodiment, support frames 22 are symmetrically connected to both sides of the inner wall of the mounting cavity 11. The length direction of the support frame 22 is parallel to the width direction of the cabinet 1. The support frame 22 is connected to the bottom of the guide post 34. The end of the third connecting member 37 away from the pull block 36 extends into the support frame 22 and is fixedly connected to the driving block 23. The driving block 23 is fixedly connected to the mounting plate 21. When the third connector 37 pulls the drive block 23 to move within the support frame 22, the drive block 23 drives the mounting plate 21 to move synchronously. For example, the third limiting hole is a rectangular through hole opened along the length of the support frame 22, and the third limiting hole can limit the movement of the drive block 23.

[0060] Optionally, see [link to relevant documentation] Figure 4 The mounting mechanism 2 also includes a reset member 24. The reset member 24 is sleeved outside the third connecting member 37, with one end connected to the side wall of the support frame 22 and the other end abutting against the driving block 23. The reset member 24 is used to drive the driving block 23 to reset. For example, the reset member 24 can be a spring, which is simple to operate and convenient to use.

[0061] Optionally, such as Figure 2 and Figure 3 As shown, the power control cabinet also includes a push mechanism 4, a drive mechanism 5, and a transmission gear set 6. The drive mechanism 5 is connected to the push mechanism 4 via the transmission gear set 6. The drive mechanism 5 drives the push mechanism 4 to rotate, thereby causing the push mechanism 4 to rotate the protective cover 31, which in turn drives the mounting plate 21 to move.

[0062] like Figure 2 , Figure 3 and Figure 6As shown, the pushing mechanism 4 includes a rotating screw 41 and a first hinge rod 42. The rotating screw 41 is rotatably connected to the cabinet 1 and perpendicular to the axis of rotation of the protective cover 31. One end of the first hinge rod 42 is sleeved on the rotating screw 41 and threadedly connected to it. The other end of the first hinge rod 42 is hinged to the protective cover 31. When the rotating screw 41 rotates, it can drive one end of the first hinge rod 42 to move along the axis of the rotating screw 41, thereby driving the protective cover 31 to rotate relative to the cabinet 1. Specifically, in this embodiment, the pushing mechanism 4 also includes a pushing block 43 and a connecting plate 44. The pushing block 43 and the connecting plate 44 are respectively hinged to the two ends of the first hinge rod 42. The pushing block 43 is sleeved on the rotating screw 41 and threadedly connected to it. The connecting plate 44 is fixedly connected to the protective cover 31. The rotating screw 41 and the pushing block 43 form a screw drive structure. When the rotating screw 41 rotates, the pushing block 43 can move along its surface, thereby driving the first hinge rod 42 to move. Furthermore, the pushing mechanism 4 is provided in two sets. The two sets of pushing mechanisms 4 can make the force on the protective cover 31 more even when rotating, and avoid the phenomenon of jamming when the protective cover 31 rotates. Rectangular grooves are opened on both sides of the surface of the cabinet 1. The two rotating screws 41 are respectively located in the two rectangular grooves. The inner wall size of the rectangular groove is adapted to the surface size of the pushing block 43. The pushing block 43 can move along the surface of the rotating screw 41 in the rectangular groove. When the protective cover 31 rotates to close the first opening 12, the first hinge rod 42 can be folded and stored inside the rectangular groove.

[0063] like Figure 2 , Figures 6-9 As shown, the output end of the drive mechanism 5 is connected to the input gear 61 of the transmission gear set 6. The output gear 63 of the transmission gear set 6 is coaxially connected to the rotating screw 41. The output end of the drive mechanism 5 can drive the rotating screw 41 to rotate around its own axis through the transmission gear set 6. Specifically, in this embodiment, the transmission gear set 6 also includes a conveyor belt 62. The output gears 63 correspond one-to-one with the rotating screw 41, and two are also provided. The two output gears 63 are respectively located on both sides of the cabinet 1. The conveyor belt 62 is sleeved around the two output gears 63 and meshes with them respectively. The conveyor belt 62 also meshes with the input gear 61. That is to say, the output end of the drive mechanism 5 drives the input gear 61 to rotate, the input gear 61 drives the conveyor belt 62 to rotate, and the conveyor belt 62 drives the two output gears 63 to rotate. The gear transmission has high transmission accuracy, reliable transmission, and long service life.

[0064] Specifically, see Figures 7-9The drive mechanism 5 includes a fixed frame 51, a rotating shaft 52, a driven gear 53, and a rack 54. The fixed frame 51 is connected to the cabinet 1 and extends along the side of the cabinet 1; the rotating shaft 52 is rotatably connected to the fixed frame 51 and coaxially connected to the input gear 61 of the transmission gear set 6; the driven gear 53 is coaxially connected to the rotating shaft 52; the rack 54 is meshed with the driven gear 53 and can slide along the length direction of the fixed frame 51. Exemplarily, in this embodiment, the fixed frame 51 is cuboid in shape, connected to the bottom of the cabinet 1, and parallel to the length direction of the cabinet 1. The rotating shaft 52 is rotatably connected to the fixed frame 51 via a bearing. The rack 54 is rectangular and its length is less than the length of the fixed frame 51, so the rack 54 can move within the fixed frame 51. By controlling the rack 54 to move along the length of the fixed frame 51, the driven gear 53 that meshes with it is driven to rotate. The driven gear 53 drives the rotating shaft 52 to rotate, which in turn drives the input gear 61 of the transmission gear set 6 to rotate.

[0065] For more details, please refer to [link / reference]. Figure 8 and Figure 9 The driving mechanism 5 also includes a first connecting member 55, a limiting plate 56, a limiting pin 57, and a limiting clamp 58. A first limiting hole is formed along the length of the side wall of the fixed frame 51. The first connecting member 55 passes through the first limiting hole, and its two ends are respectively connected to the rack 54 and the limiting plate 56. A threaded hole is formed on the limiting plate 56, and the limiting pin 57 is threadedly connected to the threaded hole. The limiting clamp 58 is connected to the end of the limiting pin 57 near the fixed frame 51. Exemplarily, in this embodiment, the first limiting hole is a rectangular through hole formed along the length of the fixed frame 51. The inner wall size of the first limiting hole is adapted to the surface size of the first connecting member 55, and the first limiting hole can guide and limit the movement of the first connecting member 55. The surface size of the limiting plate 56 is larger than the width of the first limiting hole, which can prevent the rack 54 from causing the first connecting member 55 to retract into the interior of the fixed frame 51 during movement. Furthermore, a rubber pad is affixed to the side of the limiting clamp 58 near the surface of the fixed frame 51. An operating disc is fixedly connected to the end of the limiting pin 57 furthest from the limiting clamp 58. Rotating the limiting pin 57 causes it to move relative to the limiting plate 56, causing the limiting pin 57 to press against the surface of the fixed frame 51, thus locking the rack 54. The rubber pad on the surface of the limiting clamp 58 increases friction, while the operating disc fixedly connected to one end of the limiting pin 57 limits its movement, preventing it from retracting into the limiting plate 56 during rotation.

[0066] In this embodiment, the power control cabinet, through the second hinge rod 33 and the third connecting member 37, allows the two sets of second hinge rods 33 to simultaneously pull the pull block 36 within the guide post 34 when the protective cover 31 is unfolded. This enables the two sets of third connecting members 37 to pull the mounting plate 21 as a whole, thereby allowing the mounting plate 21 and the electrical equipment 100 on it to move from the inside of the mounting cavity 11 towards the first opening 12. This facilitates routine maintenance or upkeep of the electrical equipment 100 without requiring operators to work within the confined space of the power control cabinet. It avoids the inconvenience caused by the limited internal space of the power control cabinet, reduces the difficulty of maintenance, improves efficiency, and minimizes economic losses during power distribution network maintenance. The movement of the rack 54 drives the two sets of rotating screws 41 to rotate, causing the two sets of first hinge rods 42 to simultaneously rotate the protective cover 31. The limiting pin 57 can be used to fix the rack 54 when it is not in use, so that the protective cover 31 can be operated without the need for the operator to support it. When the operator maintains the power control cabinet, he / she can operate it with both hands.

[0067] Example 2

[0068] This embodiment provides a power control cabinet, which is basically the same as the power control cabinet provided in Embodiment 1. The difference between this embodiment and Embodiment 1 is that in this embodiment, the output end of the drive mechanism 5 is directly hinged to the protective cover plate 31, and the output end of the drive mechanism 5 drives the protective cover plate 31 to flip. Exemplarily, the drive mechanism 5 includes two sets of electric push rods, the fixed ends of which are respectively located on both sides of the cabinet body 1, and the telescopic rods of the electric push rods are connected to the protective cover plate 31. When the telescopic rods of the electric push rods extend, the protective cover plate 31 opens the first opening 12; when the telescopic rods of the electric push rods retract, the protective cover plate 31 closes the first opening 12.
