Description

Technical Field

[0001] This invention relates to the field of low-voltage complete power distribution equipment technology, specifically to a power distribution control center. Background Technology

[0002] Power distribution control centers typically employ a drawer-type structure to arrange functional units, which are electrically connected to busbars and control circuits via plug-in methods. To meet the requirements for equipment operational stability, existing technologies usually incorporate ventilation structures or airflow channels inside the cabinet to dissipate heat from each drawer-type functional unit.

[0003] However, in the existing power distribution control center structure, the insertion of drawer-type functional units usually directly triggers the closing of electrical contacts. There is no structural constraint between the establishment of the electrical connection and the formation of the airflow channel inside the cabinet. That is, when the drawer-type functional unit is in the inserted state, its electrical contacts can be closed, but whether the corresponding airflow channel is fully formed or whether the air duct is in an effective conductive state is not structurally limited.

[0004] In actual operation, if the drawer-type functional unit is not fully in place or the airflow guide structure does not form a stable airflow path, the electrical contacts may still close, resulting in a mismatch between the operating conditions and the structural state.

[0005] Therefore, it is necessary to provide a structural arrangement that establishes a clear structural relationship between the electrical connection of the drawer-type functional units and the formation of the internal flow channels of the cabinet, so as to improve the consistency of structural operation. Summary of the Invention

[0006] The purpose of this invention is to provide a power distribution control center to solve the technical problem in the prior art that there is no clear structural relationship between the establishment of electrical connections of drawer-type functional units and the formation of internal flow channels in the cabinet.

[0015] As a further embodiment of the present invention: the ventilation platform has a buffer cylinder fixedly connected to one end near the drawer structure. The buffer cylinder is in the shape of a quadrilateral cylinder, and a buffer pad is fixedly connected to the side end of the buffer cylinder. A buffer groove is opened on the side end of the drawer structure, and the buffer groove is slidably connected to the inner wall of the buffer pad.

[0016] As a further aspect of the present invention: the bottom of the drawer structure is provided with a plurality of heat dissipation holes along the width direction of the power distribution cabinet, and the drawer structure is provided with a connecting hole with a cross-section in the shape of a frustum at one end near the air outlet groove. The connecting hole communicates with the inner cavity of the heat dissipation hole, and the inner diameter of the connecting hole near the air outlet groove is larger than the inner diameter near the heat dissipation hole.

[0017] As a further aspect of the present invention: the abutment block is wedge-shaped, the cross-section of the abutment block near the flip plate is arc-shaped, the top of the abutment block is slidably connected to the flip plate, the abutment block is fixedly connected to the drawer structure through an extension component, and a connecting pad with a triangular cross-section is fixedly connected to the inner wall of the air vent groove, the connecting pad being located at the bottom of the abutment block.

[0018] As a further embodiment of the present invention: the extension assembly includes: an extension column, an extension tube, and an extension spring.

[0021] The beneficial effects of this invention are:

[0022] 1. The abutment block on the drawer structure first contacts the flip plate, which then rotates counterclockwise. The flip plate flips along its top, gradually releasing its obstruction of the air outlet groove. Airflow begins to flow out from the air outlet groove and then contacts the drawer structure. At this time, the plug begins to pass through the air outlet groove and enter the ventilation chamber. Therefore, before the plug is inserted into the contact groove, the airflow begins to contact the drawer structure, preventing the drawer structure from not receiving airflow when the plug is installed.

[0023] 2. The baffle and the flip plate are respectively located on the upper and lower sides of the air outlet slot. The airflow through the channel formed by the baffle and the flip plate reduces the space for airflow to flow in the ventilation cavity, thereby reducing the effective path of airflow from the air inlet channel to the air outlet slot.

[0024] 3. The plug is fully inserted into the contact slot to form a closed contact. When the airflow flows out from the air outlet slot, the airflow directly contacts the drawer structure. The close fit between the drawer structure and the vent platform can prevent the airflow from flowing out between the drawer structure and the vent platform, ensuring that the airflow can fully handle the heat generated by the drawer structure during operation.

[0025] 4. When each drawer structure is installed in the distribution cabinet, it will have a corresponding partition and flip plate to form an independent closed channel, ensuring that the airflow from the inner cavity of the air inlet channel comes into contact with the drawer structure through the closed channel. For drawer structures that are not installed, the flip plate blocks the air outlet slot, thereby ensuring that when the airflow dissipates heat from different drawer structures, the heat treatment between the drawer structures will not affect each other, avoiding the phenomenon of airflow causing disorder in the heat dissipation of the drawer structure.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1, as Figures 1 to 2As shown, a power distribution control center includes: a distribution cabinet 1, a venting platform 11, and a flip-up plate 18. The distribution cabinet 1 has several sets of drawer structures 23 arranged along its height. The inner wall of the distribution cabinet 1 has several sets of contact slots 17 equidistantly arranged along its height. The drawer structures 23 are mounted inside the distribution cabinet 1 via guide rails 24 at both ends. A plug 15 is fixedly connected to one end of the drawer structure 23 near the contact slot 17, and abutment blocks 39 are provided on both sides of the plug 15. The venting platform 11 is fixedly connected to the inner wall of the distribution cabinet 1. An air outlet 25 and an air inlet channel 27 are opened on the side of the venting platform 11. The air outlet 25 communicates with a ventilation cavity 14 opened on the venting platform 11. The air inlet channel 27 communicates with the ventilation cavity 14 through a rotating groove 29 opened on the venting platform 11. 4. The flip plate 18 is rotatably connected to the inner wall of the air outlet groove 25 at both ends. The flip plate 18 is fixedly connected to the connecting rod 34 through the reset column 36. The flip plate 18 is fixedly connected to the rotating rod 37 at the end away from the reset column 36. The bottom of the flip plate 18 is provided with a partition 12. The flip plate 18 and the partition 12 are located on the upper and lower sides of the air outlet groove 25, respectively. The partition 12 is fixedly connected to the inner wall of the ventilation chamber 14. The ventilation platform 11 is provided with a reset hole 33 at the end away from the rotating groove 29. The reset column 36 is rotatably connected to the inner wall of the reset hole 33. The inner cavity of the reset hole 33 is provided with a reset spring 35. The reset spring 35 is sleeved on the connecting rod 34. The two ends of the reset spring 35 are fixedly connected to the reset column 36 and the ventilation platform 11, respectively. The side end of the rotating rod 37 is rotatably connected to the ventilation platform 11.

[0047] The airflow first enters the inner cavity of the air intake channel 27 opened in the ventilation platform 11 and flows, and then enters the inner cavity of the ventilation chamber 14 through the air intake channel 38. The partition 12 divides the inner cavity of the ventilation chamber 14. At this time, the flip plate 18 blocks the air outlet slot 25 to prevent the airflow from passing through the air outlet slot 25 and entering the inner cavity of the power distribution cabinet 1. Drawer structure 23 is placed on guide rail 24, and then drawer structure 23 slides along guide rail 24 toward vent 11. The abutment block 39 on drawer structure 23 first contacts flip plate 18, and abutment block 39 begins to abut flip plate 18 to rotate counterclockwise. Flip plate 18 flips along its own top, and flip plate 18 gradually releases the blocking effect on air outlet groove 25. Airflow begins to flow out from air outlet groove 25, and then airflow begins to contact drawer structure 23. At this time, plug 15 begins to pass through air outlet groove 25 and enter the inner cavity of vent 14. Therefore, before plug 15 is inserted into contact groove 17, airflow begins to contact drawer structure 23, so that drawer structure 23 does not receive airflow when installed with plug 15 attached.

[0048] When the supporting block 39 abuts against the flip plate 18 and rotates it counterclockwise by 90 degrees, the flip plate 18 and the partition plate 12 form a closed channel in the inner cavity of the ventilation chamber 14. The airflow enters the inner cavity of this channel through the air inlet channel 38 and then flows out through the air outlet groove 25. The partition plate 12 and the flip plate 18 are respectively located on the upper and lower sides of the air outlet groove 25. The airflow through the channel formed by the partition plate 12 and the flip plate 18 reduces the space for the airflow to flow in the inner cavity of the ventilation chamber 14, thereby reducing the effective path for the airflow to flow out from the air inlet channel 38 to the air outlet groove 25.

[0049] When the drawer structure 23 and the vent 11 are in contact, the plug 15 is fully inserted into the contact groove 17, forming a closed contact. When the airflow flows out from the vent groove 25, the airflow directly contacts the drawer structure 23. The contact between the drawer structure 23 and the vent 11 can prevent the airflow from flowing out between the drawer structure 23 and the vent 11, ensuring that the airflow can fully handle the heat generated by the drawer structure 23 during operation.

[0050] It should be noted that multiple drawer structures 23 can be installed inside the distribution cabinet 1. When each drawer structure 23 is installed inside the distribution cabinet 1, it will have a corresponding partition 12 and a flip plate 18 forming an independent closed channel. This ensures that the airflow from the inner cavity of the air inlet channel 27 comes into contact with the drawer structure 23 through the closed channel. For drawer structures 23 that are not installed, the flip plate 18 blocks the air outlet slot 25, thereby ensuring that when the airflow dissipates heat from different drawer structures 23, the heat treatment between the drawer structures 23 will not affect each other, thus avoiding the phenomenon of disorder in the airflow dissipating heat from the drawer structures 23.

[0051] When the drawer structure 23 is removed from the distribution cabinet 1, the plug 15 first releases contact with the contact groove 17, and then the plug 15 gradually passes through the air outlet groove 25 and leaves the inner cavity of the ventilation chamber 14. At this time, the abutment block 39 also moves out along with the drawer structure 23. The top of the abutment block 39 slides along the flip plate 18. The abutment block 39 provides limiting support for the flip plate 18. The flip plate 18 remains parallel to the partition 12. Therefore, during the process of the plug 15 moving out of the inner cavity of the ventilation chamber 14, the flip plate 18 and the partition 12 maintain a closed channel for the flow of air.

[0052] When the plug 15 is fully inserted through the vent groove 25, the retaining block 39 begins to move out of the vent groove 25. When the retaining block 39 and the vent groove 25 are completely removed, the elastic force provided by the reset spring 35 drives the flip plate 18 to rotate clockwise. At this time, the flip plate 18 begins to reset. The flip plate 18 drives the reset column 36 and the rotating rod 37 to rotate. The rotating rod 37 passes through the side end of the ventilation platform 11 and rotates along the inner wall of the ventilation platform 11. The reset column 36 drives the connecting rod 34 to rotate. The rotating rod 37 and the connecting rod 34 rotate along the ventilation platform 11, providing a limiting support for the rotation of the flip plate 18. When the flip plate 18 blocks the vent groove 25, the flip plate 18 stops rotating.

[0053] Furthermore, when the flip plate 18 blocks the air outlet slot 25, the airflow fills the inner cavity of the ventilation chamber 14. The air pressure generated by the airflow in the ventilation chamber 14 acts on the plug 15, which hinders the counterclockwise rotation of the flip plate 18 by the holding block 39. Therefore, in this invention, a rotating groove 29 with a semi-circular cross-section is provided on the side end of the ventilation platform 11. The inner cavity of the rotating groove 29 is connected to the air intake channel 38. The air intake channel 38 has a semi-circular cross-section, and its radius is smaller than that of the rotating groove 29. The inner cavity of the groove 29 is provided with a rotating plate 30, which is fixedly connected to the side wall of the rotating rod 37. The rotating plate 30 rotates around the axis of the rotating rod 37 along the inner wall of the rotating groove 29. When the flip plate 18 blocks the air outlet groove 25, the rotating plate 30 is located in the lower half of the rotating groove 29. The rotating plate 30 blocks the air inlet channel 38, preventing the airflow in the air inlet main channel 27 from passing through the air inlet channel 38 and entering the inner cavity of the ventilation chamber 14, thus generating air pressure on the flip plate 18 and preventing the air pressure from hindering the flipping of the flip plate 18.

[0054] When the flip plate 18 flips counterclockwise, it drives the rotating rod 37 to rotate. The rotating rod 37 drives the rotating plate 30 to rotate along the rotating groove 29. The rotating plate 30 gradually releases the blockage of the air intake channel 38, and the airflow begins to pass through the air intake channel 38 and enter the inner cavity of the ventilation chamber 14. Since the flip plate 18 does not form a closed channel with the partition 12 during the flipping process, the airflow cannot fully pass through the air intake channel 38 to enter the inner cavity of the ventilation chamber 14 because the rotating plate 30 gradually releases the blockage of the air intake channel 38. The rotating plate 30 has the effect of blocking and opening the air intake channel 38, and the rotating plate 30 has the effect of adjusting the effective area of ​​the airflow passing through the air intake channel 38 during the rotation process.

[0055] When the flip plate 18 rotates counterclockwise by 90 degrees, the top of the rotating plate 30 and the rotating groove 29 abut against each other. The rotating plate 30 transmits this abutting force to the flip plate 18 through the rotating rod 37, thereby providing a limiting effect for the flip plate 18 and preventing the flip plate 18 from flipping more than 90 degrees. When the flip plate 18 resets, the bottom of the rotating plate 30 and the rotating groove 29 abut against each other, thereby preventing the flip plate 18 from passing through the air outlet groove 25 and failing to fully seal the air outlet groove 25.

[0056] Example 2, as Figures 5 to 6 and Figures 9 to 13 As shown, in this invention, the top of the flip plate 18 is provided with a sealing plate 19. The sealing plate 19 has an "L" shaped cross-section and is used to seal the contact groove 17. The top of the sealing plate 19 is fixedly connected to a limiting plate 22 by two sets of limiting components. The two sets of limiting components are respectively set on both sides of the plug 15. The two ends of the limiting plate 22 are respectively fixedly connected to the power distribution cabinet 1 and the ventilation platform 11. When the air outlet groove 25 is not inserted into the contact groove 17, the contact groove 17 is in the open direction, and the contact groove 17 lacks sealing protection. When the flip plate 18 seals the air outlet groove 25, the sealing plate 19 seals the contact groove 17. When the flip plate 18 starts to flip counterclockwise, the airflow begins to enter the ventilation chamber 14. In the inner cavity, at this time, the sealing plate 19 is in a state of sealing the contact groove 17. When the side end of the flip plate 18 and the sealing plate 19 come into contact, the flip plate 18 moves upward against the sealing plate 19. At the same time, the side end of the sealing plate 19 begins to slide along the top of the flip plate 18. At this time, the sealing plate 19 begins to compress the limiting component. When the flip plate 18 rotates counterclockwise by ninety degrees, the bottom of the sealing plate 19 and the top of the flip plate 18 are fully fitted together. In this invention, in order to avoid the flip plate 18 from getting stuck on the inner wall of the distribution cabinet 1, the bottom of the flip plate 18 is arc-shaped. The fit between the sealing plate 19 and the flip plate 18 can seal the gap between the flip plate 18 and the distribution cabinet 1.

[0057] In some specific implementations, the limiting component includes: a limiting tube 20 and a limiting post 21. The top end of the limiting post 21 is fixedly connected to the limiting plate 22, and the limiting post 21 is slidably connected to the inner wall of the limiting tube 20. The bottom end of the limiting tube 20 is fixedly connected to the sealing plate 19. Two sets of limiting grooves 31 are provided on the inner wall of the limiting tube 20. The two sets of limiting grooves 31 are symmetrically arranged along the axial section of the limiting post 21. Limiting blocks 32 are slidably connected to the inner wall of the limiting grooves 31. The limiting blocks 32 are fixedly connected to the side end of the limiting post 21. When the sealing plate 19 moves vertically upward, the sealing plate 19 moves vertically upward with the limiting tube 20. The inner wall of the limiting tube 20 slides along the limiting post 21. The limiting blocks 32 fixed at both ends of the limiting post 21 slide along the inner wall of the limiting grooves 31. The limiting post 21 is fixed by the limiting plate 22. The limiting tube 20 provides limiting guidance for the sealing plate 19 along the limiting post 21. When the sealing plate 19 is reset, the sealing plate 19 moves vertically downward with the limiting tube 20. When the limiting block 32 and the top of the limiting tube 20 abut against each other, the limiting tube 20 stops moving downward and pulls the sealing plate 19 to stop moving downward, thereby realizing the function of the sealing plate 19 to continue to seal the contact groove 17.

[0058] It should be noted that the sealing plate 19 only begins to move upward after the flip plate 18 flips. When the sealing plate 19 resets, the flip plate 18 continues to reset. During this process, the airflow continues to flow inside the venting cavity 14. The airflow can discharge the dust inside the venting cavity 14 from the air outlet groove 25, thus preventing the dust from coming into contact with the contact groove 17.

[0059] Furthermore, when the flip plate 18 begins to flip, airflow begins to flow out from the air outlet 25. However, at this time, there is a gap between the drawer structure 23 and the ventilation platform 11, and airflow will flow into the inner cavity of the distribution cabinet 1 from between the drawer structure 23 and the ventilation platform 11. Therefore, in this invention, a buffer cylinder 9 is fixedly connected to one end of the ventilation platform 11 near the drawer structure 23. The buffer cylinder 9 is a quadrilateral cylinder, and a buffer pad 8 is fixedly connected to the side end of the buffer cylinder 9. A buffer groove 10 is opened on the side end of the drawer structure 23, and the buffer groove 10 is slidably connected to the inner wall of the buffer pad 8. When the drawer... When structure 23 moves to ventilator 11, buffer pad 8 is first inserted into buffer groove 10. At this time, flip plate 18 is not flipped. Buffer pad 8 slides along the inner wall of buffer groove 10. Buffer cylinder 9 begins to enter the inner cavity of buffer groove 10. At this time, flip plate 18 begins to flip. When airflow flows out from air outlet groove 25, it enters the inner cavity of buffer cylinder 9 and then directly contacts drawer structure 23 through buffer cylinder 9. Buffer cylinder 9 provides a guiding channel for airflow between drawer structure 23 and ventilator 11, preventing airflow from entering the inner cavity of distribution cabinet 1. When the buffer pad 8 begins to contact the drawer structure 23, the drawer structure 23 is about to come into contact with the vent 11. When the drawer structure 23 and the vent 11 come into contact, the buffer pad 8 is deformed by the pressure of the drawer structure 23 and the buffer cylinder 9. The buffer pad 8 fills the inner cavity of the buffer groove 10. The buffer pad 8 is plastic and can provide a buffering effect for the contact between the drawer structure 23 and the buffer cylinder 9, avoiding the phenomenon of rigid collision between the drawer structure 23 and the buffer cylinder 9.

[0060] Example 3, as Figures 1 to 7 and Figure 16 As shown, the bottom of the drawer structure 23 has several heat dissipation holes 7 along the width direction of the distribution cabinet 1. The drawer structure 23 has a connecting hole 13 with a frustum-shaped cross-section at one end near the air outlet slot 25. The connecting hole 13 communicates with the inner cavity of the heat dissipation hole 7. The inner diameter of the connecting hole 13 near the air outlet slot 25 is larger than the inner diameter near the heat dissipation hole 7. When the airflow directly contacts the drawer structure 23, the airflow enters the heat dissipation hole 7 through the connecting hole 13. The shape of the connecting hole 13 increases the effective area for the airflow to enter the inner cavity of the connecting hole 13. At the same time, it accelerates the airflow into the inner cavity of the heat dissipation hole 7. The axis of the heat dissipation hole 7 can be set to a continuous "S" shape, which increases the path of the airflow in the heat dissipation hole 7.

[0061] In some specific implementations, the distribution cabinet 1 has a distribution door 2 hinged to the end away from the ventilation platform 11. A flexible sealing door 3 is fixedly connected to the side of the distribution door 2, abutting against the drawer structure 23. The sealing door 3 has several vent holes 6 along the width of the distribution cabinet 1, which are aligned sequentially with several heat dissipation holes 7. Inside the distribution door 2, several vent grooves 5 are formed along the height of the distribution cabinet 1. The outlet ends of the vent grooves 5 are inclined towards the bottom of the distribution cabinet 1. The heat dissipation holes 7 connect to the ventilation platform 1 through the vent holes 6. The inner cavity of the exhaust slot 5 is connected. When the airflow flows out from the heat dissipation hole 7, the airflow directly enters the inner cavity of the exhaust hole 6. The airflow enters the inner cavity of the exhaust slot 5 through the exhaust hole 6 and is then discharged through the exhaust slot 5. In this invention, the exhaust hole 6 and the exhaust slot 5 are set separately for different drawer structures 23 to ensure that the airflow carrying heat is discharged from the power distribution cabinet 1 without affecting each other. For some exhaust slots 5 where no airflow passes through, the outlet end of the exhaust slot 5 is set to prevent impurities outside the power distribution cabinet 1 from entering the inner cavity of the exhaust slot 5.

[0062] Example 4, as Figures 4 to 6 and Figures 16 to 17 As shown, the abutment block 39 is wedge-shaped, and its cross-section at the end near the flip plate 18 is arc-shaped. The top of the abutment block 39 is slidably connected to the flip plate 18. The abutment block 39 is fixedly connected to the drawer structure 23 via an extension assembly. A connecting pad 28 with a triangular cross-section is fixedly connected to the inner wall of the vent groove 25. The connecting pad 28 is located at the bottom of the abutment block 39. In this invention, the drawer structure 23 drives the flip plate 18 to rotate counterclockwise by driving the abutment block 39 to abut against it. However, when the flip plate 18 rotates counterclockwise by 90 degrees, the plug 15 is inserted into the contact groove 17. Therefore, to avoid the plug 15 and the flip plate 18 from colliding... The phenomenon of abutment occurs as the drawer structure 23 moves towards the vent platform 11. The abutment block 39 first abuts against the flip plate 18 via the extension assembly. The surface of the flip plate 18 slides along the top of the abutment block 39. When the flip plate 18 rotates counterclockwise until it is no longer in contact with the plug 15, the plug 15 begins to pass through the vent groove 25 and enter the vent cavity 14. When the flip plate 18 rotates counterclockwise to ninety degrees, the abutment block 39 abuts against the distribution cabinet 1, with the top of the abutment block 39 and the bottom of the flip plate 18 fitting together. The plug 15 is not yet inserted into the contact groove 17, and the extension assembly is compressed by the pressure of the abutment block 39 and the drawer structure 23. When the plug 15 begins to move out of the contact groove 17, the abutment block 39 is in a state of abutment against the distribution cabinet 1, the extension assembly begins to reset, and then moves with the abutment block 39 out of the vent cavity 14.

[0063] It should be noted that when the flip plate 18 is reset, the bottom end of the flip plate 18 contacts the connecting pad 28, the connecting pad 28 is squeezed and deformed, and the connecting pad 28 seals the gap between the flip plate 18 and the air outlet groove 25.

[0064] In some specific embodiments, the extension assembly includes: an extension post 40, an extension tube 41, and an extension spring 42. The extension post 40 and the extension tube 41 have rectangular cross-sections. The extension post 40 is fixedly connected to the side end of the abutment block 39, and slidably connected to the inner wall of the extension tube 41. The side end of the extension tube 41 is fixedly connected to the drawer structure 23. The extension spring 42 is disposed within the inner cavity of the extension tube 41, and its two ends are fixedly connected to the drawer structure 23 and the extension post 40, respectively. When the abutment block 39 and the flip plate 18 abut against each other, the drawer structure 23 pushes the extension post 40 to move through the elastic force of the extension spring 42. The extension post 40 then pushes the abutment block 39 to move, and the elastic force of the extension spring 42 continues to move. The final force is greater than the elastic force provided by the return spring 35 to the flip plate 18. When the abutment block 39 and the distribution cabinet 1 abut, the drawer structure 23 moves the extension tube 41 towards the abutment block 39. The inner wall of the extension tube 41 slides along the extension column 40. The extension spring 42 begins to compress. When the extension assembly is reset, the drawer structure 23 moves the extension tube 41 first. After the extension spring 42 is reset, the extension spring 42 pulls the extension column 40 to move. The extension column 40 pulls the abutment block 39 to move. Throughout the process, the extension column 40 always abuts against the inner wall of the extension tube 41. The shape of the extension column 40 and the extension tube 41 is designed to prevent the extension column 40 from rotating on the inner wall of the extension tube 41.

[0065] The foregoing has described several embodiments of the present invention in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of the invention. All equivalent variations and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
