Description

Technical Field

[0001] The present invention belongs to the technical field of ring network cabinets, and particularly relates to a highly efficient heat dissipation type ring network cabinet structure. Background Art

[0002] A ring main unit is a set of high-voltage switchgear installed in a steel plate metal cabinet or made into a prefabricated sectionalized ring main unit electrical equipment.

[0003] At present, there are various fully enclosed insulated ring main switches on the market, but generally there is a disadvantage of poor protection. Since the inside of the enclosed switchgear cannot be effectively ventilated, a large amount of heat is generated when the switchgear is working and accumulates in the cabinet and cannot be dissipated in time. For the above technical problems, the applicant has retrieved some prior arts. For example, in the Chinese patent with the patent publication number CN211508240U, when in use, heat is conducted through a heat conduction plate and transferred to the heat sink, and the heat sink dissipates heat directly from the inside of the heat dissipation port. However, after long-term use, the temperature of the heat conduction plate will rise, so that the temperature difference between the heat conduction plate and the hot air decreases after the temperature of the heat conduction plate rises, and further the heat exchange efficiency decreases, resulting in poor heat dissipation effect on the ring main unit. Summary of the Invention

[0004] The purpose of the present invention is to provide a highly efficient heat dissipation type ring network cabinet structure, aiming to solve the technical problem that the heat exchange efficiency decreases after long-term use in the prior art, resulting in poor heat dissipation effect on the ring main unit.

[0005] The present invention is realized as follows. A highly efficient heat dissipation type ring network cabinet structure includes a housing. One side of the housing is hinged with a cabinet door. A partition net plate and a partition board are fixedly installed inside the housing. A plurality of filter nets are fixedly installed on the side wall of the housing away from the cabinet door.

[0006] A plurality of frame-shaped closed plates are fixedly installed on the surface of the partition board close to the partition net plate. A through groove located inside the closed plate is formed on the partition board. There is a gap between the side of the through groove and the inner wall of the closed plate. A second cover plate is slidably installed at one end of the closed plate away from the partition board. The closed plate is provided with an adjusting component for adjusting the position of the second cover plate.

[0007] A moving plate is slidably installed on the surface of the partition board away from the partition net plate. The moving plate moves along a direction perpendicular to the partition board, and a plurality of heat conduction plates are rotatably installed on the moving plate. The positions of the heat conduction plates correspond to the positions of the through grooves, and a plurality of spaced heat sinks are fixedly installed on both side surfaces of the heat conduction plates. In the working state, the heat conduction plates are in contact with the partition board, and the heat sinks on one side surface of the heat conduction plates extend into the through grooves. A power component for driving the heat conduction plates to move and adjust the angle is arranged inside the housing.

[0008] Further technical solution: The adjusting component includes an electromagnet and a second magnet. There are two sets of electromagnets which are fixedly installed at both ends of the closed plate, and two sets of second magnets which are fixedly installed at both ends of the second cover plate. The electromagnet and the second magnet at the same end are correspondingly positioned. When the electromagnet is energized, it has the opposite magnetism to the corresponding electromagnet and pushes the second cover plate away from the closed plate.

[0009] Further technical solution: The power component includes a second reciprocating lead screw which is rotatably installed on the partition and perpendicular to the partition. The second reciprocating lead screw is rotationally connected to the moving plate and is connected to a rotary power member fixedly installed in the housing.

[0010] Further technical solution: The rotary power member is fixedly installed at the bottom inside the housing and drives the first reciprocating lead screw to rotate. The first reciprocating lead screw is distributed in the vertical direction and is in the same vertical plane as the second reciprocating lead screw. The first reciprocating lead screw and the second reciprocating lead screw are rotationally connected through a gear set.

[0011] Further technical solution: The power component further includes a ratchet. There are multiple sets of ratchets which are respectively fixedly installed on the rotating shafts of the heat conducting plates. The ratchets are engaged with the racks fixedly installed on the partition. The racks are parallel to the second reciprocating lead screw and the ends of the racks close to the partition are not provided with teeth. A fourth magnet is fixedly installed on the rotating shaft of the heat conducting plate. The fourth magnet is in sliding contact with the moving plate and the heat conducting plate is made of magnetic material.

[0012] Further technical solution: The first reciprocating lead screw drives the lifting frame slidably installed on the inner wall of the housing to move. Multiple sets of heat dissipation fans are fixedly installed on the lifting frame, and the positions of the heat dissipation fans correspond to the filter screens.

[0013] Further technical solution: A first cover plate is slidably installed in the closed plate. The first cover plate is installed through multiple sets of guide rods. When the first cover plate contacts the partition, it closes the through groove and there is a gap between the side of the first cover plate and the closed plate. The first cover plate is made of magnetic material and first magnets for adsorbing and fixing the first cover plate are fixedly installed on the partition at both ends of the through groove.

[0014] Further technical solution: Support rods located on both sides of the heat dissipation fins are fixedly installed on both side surfaces of the heat conducting plate. Third magnets are fixedly installed at the ends of the support rods. When the third magnets extend into the through groove, they adsorb the first cover plate.

[0015] Further technical solution: A first communication chamber and a second communication chamber are fixedly installed on the surface of the partition plate away from the partition net plate. The first communication chamber is communicated with the area enclosed by the closing plate through multiple suction pipes, and the second communication chamber is communicated with the area enclosed by the closing plate through multiple air supply pipes. The suction pipes and the air supply pipes are connected to both ends of the closing plate. An air pump is fixedly installed on the partition plate, and the air pump is communicated with the first communication chamber and the second communication chamber through a first communication pipe and a second communication pipe respectively. A filter is fixedly installed on the second communication pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The heat generated by the equipment inside the housing is quickly released through the heat sinks and the heat conducting plate. When the temperature of the heat sinks located inside the closing plate is relatively high, the second cover plate is brought into contact with the closing plate. Then, the guide plate is driven to move and adjusted by the power assembly so that the heat sinks with lower temperature enter the closing plate. After that, when the second cover plate is moved away from the closing plate, the hot air can exchange heat with the heat sinks with lower temperature. The heat sinks with higher temperature are exchanged to the outside for rapid cooling. Through the cyclic alternate heat dissipation of the two groups of heat sinks, it can ensure that the heat sinks inside the closing plate are always at a relatively low temperature, thereby improving the heat exchange efficiency between the heat sinks and the hot air inside the housing, and further improving the cooling effect inside the housing.

[0018] 2. When the guide plate leaves the partition plate, since all the air inside the area enclosed by the closing plate is hot air, at this time, the hot air will flow to the outside through the through slots, and part of the outside cold air will enter the area enclosed by the closing plate. After the guide plate comes into contact with the partition plate again later, the cold air entering the closing plate will participate in the air circulation inside the housing, so that part of the hot air inside the housing can be continuously exchanged with the outside cold air, further improving the heat dissipation efficiency of the housing.

[0019] 3. When replacing the heat sinks and the heat sinks enter the closing plate, the guide plate moves in a direction away from the partition plate. At this time, the third magnet will drive the second cover plate to move accordingly until the second cover plate comes into contact with the partition plate. Then, the third magnet is separated from the second cover plate. At this time, the second cover plate is fixed by the first magnet, and the through slots are closed from inside the closing plate by the second cover plate, so as to avoid the through slots being always in an open state during the replacement of the heat sinks, reducing the probability of impurities entering the closing plate through the through slots during the replacement of the heat sinks, and reducing the efficiency of heat dissipation caused by dust adhering to the heat sinks and the internal equipment of the housing, and further improving the heat dissipation efficiency.

[0020] 4. When the first reciprocating lead screw rotates, it drives the lifting frame to move, and then drives the cooling fan to move. The cooling fan blows the air in the area formed by the partition plate and the inner wall of the housing outwards. The outside air will also enter this area through the filter screen, realizing the circulating flow of air, improving the cooling speed of the relatively hot heat sinks removed from the closed plate, further improving the cooling efficiency inside the housing. At the same time, the air flowing outwards through the filter screen can clean the impurities adhering to the outside of the filter screen, and cooperate with the up and down movement of the cooling fan to achieve a comprehensive cleaning of the filter screen, thereby ensuring the cleanliness of the filter screen, ensuring the air intake volume of the air entering the housing, reducing the probability of dust entering the housing, and being beneficial to the heat dissipation of the housing.

[0021] 5. Within the set time after replacing the heat sinks, at this time, the first cover plate contacts the closed plate, and the area enclosed by the closed plate is in a closed state. The air in the area enclosed by the closed plate circulates through the air pump, and during the circulation process, the impurities carried in the air are filtered through the filter. After reaching the set time, the second cover plate leaves the closed plate, enabling the air in the area enclosed by the closed plate to re-participate in the circulating flow of the air inside the housing. It can perform a separate circulating filtration on the gas that is about to participate in the internal air circulation of the housing in the area enclosed by the closed plate, further reducing the probability of impurities entering the inside of the housing and adhering to the heat sinks, and further improving the heat dissipation efficiency.

Specific embodiments

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0035] As Figures 1 - 10 shown, a high-efficiency heat dissipation type ring network box structure provided by the present invention includes a housing 1, a cabinet door 2 is hinged on one side of the housing 1, a partition mesh plate 3 and a partition board 4 are fixedly installed in the housing 1, and a plurality of groups of filter screens 5 are fixedly installed on the side wall of the housing 1 away from the cabinet door 2;

[0036] A plurality of groups of frame-shaped closing plates 15 are fixedly installed on the surface of the partition board 4 close to the partition mesh plate 3. A through groove 11 located inside the closing plate 15 is formed on the partition board 4. There is a gap between the side of the through groove 11 and the inner wall of the closing plate 15. A second cover plate 16 is slidably installed at one end of the closing plate 15 away from the partition board 4, and an adjustment component 36 for adjusting the position of the second cover plate 16 is provided on the closing plate 15;

[0037] A moving plate 27 is slidably installed on the surface of the partition board 4 away from the partition mesh plate 3. The moving plate 27 moves along a direction perpendicular to the partition board 4, and a plurality of groups of heat conducting plates 28 are rotatably installed on the moving plate 27. The positions of the heat conducting plates 28 correspond to the positions of the through grooves 11, and a plurality of groups of spaced heat sinks 29 are fixedly installed on both surfaces of the heat conducting plates 28. In the working state, the heat conducting plates 28 are in contact with the partition board 4, and the heat sinks 29 on one side surface of the heat conducting plates 28 extend into the through grooves 11. A power component 37 for driving the movement and adjusting the angle of the heat conducting plates 28 is provided in the housing 1.

[0038] In actual application of this embodiment, the device is installed in the housing 1, and the installation space of the device is isolated by the partition net plate 3. In the initial state, the heat conduction plate 28 contacts the partition plate 4, so that the heat sink 29 enters the closed plate 15. At this time, the second cover plate 16 is away from the closed plate 15. The heat generated by the device in the housing 1 heats the air in the housing 1, and the hot air can enter the closed plate 15 to contact the heat sink 29 and the heat conduction plate 28, and the heat generated by the device in the housing 1 is quickly released through the heat sink 29 and the heat conduction plate 28. When the temperature of the heat sink 29 located in the closed plate 15 is relatively high, at this time, the heat exchange efficiency between the heat sink 29 and the hot air in the housing 1 is relatively low, while the temperature of the heat sink 29 located outside the closed plate 15 is relatively low. At this time, the adjusting assembly 36 drives the second cover plate 16 to contact the closed plate 15, and then the power assembly 37 drives the heat conduction plate 28 to move away from the partition plate 4. When the heat sink 29 completely leaves the through groove 11, the heat conduction plate 28 will rotate 180 degrees at this time, and then the heat conduction plate 28 resets again, so that the heat sink 29 with a lower temperature enters the closed plate 15. At this time, by the adjusting assembly 36, the second cover plate 16 is away from the closed plate 15, so that the hot air can exchange heat with the heat sink 29 with a lower temperature, and the heat sink 29 with a higher temperature is exchanged to the outside for rapid cooling. Through the cyclic alternating heat dissipation use of the two groups of heat sinks 29, it can ensure that the heat sink 29 in the closed plate 15 is always at a relatively low temperature, thereby improving the heat exchange efficiency between the heat sink 29 and the hot air in the housing 1, and further improving the cooling effect in the housing 1;

[0039] When the heat conduction plate 28 leaves the partition plate 4, since the air in the area surrounded by the closed plate 15 is all hot air, at this time, the hot air will flow to the outside through the through groove 11, and part of the outside cold air will enter the area surrounded by the closed plate 15. After the heat conduction plate 28 contacts the partition plate 4 again, the cold air entering the closed plate 15 will participate in the air circulation in the housing 1, so that part of the hot air in the housing 1 can be continuously exchanged with the outside cold air, further improving the heat dissipation efficiency of the housing 1.

[0040] As Figure 8 、 Figure 9 shown, a high-efficiency heat dissipation type ring network box structure provided by the present invention, the adjusting assembly 36 includes an electromagnet 17 and a second magnet 18. There are two groups of electromagnets 17, which are fixedly installed at both ends of the closed plate 15. There are two groups of second magnets 18, which are fixedly installed at both ends of the second cover plate 16. The electromagnet 17 and the second magnet 18 at the same end are in corresponding positions. When the electromagnet 17 is energized, it has the opposite magnetic polarity to the corresponding electromagnet 17 and pushes the second cover plate 16 away from the closed plate 15.

[0041] In actual application of this embodiment, when the heat conduction plate 28 contacts the partition plate 4 to close the through groove 11, the electromagnet 17 is energized at this time. When the electromagnet 17 is energized, it has the opposite magnetic polarity to the corresponding electromagnet 17 and pushes the second cover plate 16 away from the closing plate 15. At this time, the second cover plate 16 no longer closes the area surrounded by the closing plate 15, and the hot air in the housing 1 can enter the area surrounded by the closing plate 15 for heat exchange;

[0042] When it is necessary to replace the heat sink 29 with a lower temperature into the area surrounded by the closing plate 15, the electromagnet 17 is powered off or the direction of the current flowing through the electromagnet 17 is changed at this time. At this time, under the action of the magnetic force, the second cover plate 16 will move towards the closing plate 15 and contact the closing plate 15, and the area surrounded by the closing plate 15 is closed by the second cover plate 16. When the heat conduction plate 28 is away from the partition plate 4, the sealing state inside the housing 1 can still be ensured.

[0043] As Figure 3 、 Figure 5 shown, a highly efficient heat dissipation type ring network box structure provided by the present invention, the power assembly 37 includes a second reciprocating lead screw 34, the second reciprocating lead screw 34 is rotatably installed on the partition plate 4 and perpendicular to the partition plate 4, the second reciprocating lead screw 34 is rotatably connected to the moving plate 27, and the second reciprocating lead screw 34 is connected to the rotary power member 6 fixedly installed in the housing 1.

[0044] Specifically, the rotary power member 6 is fixedly installed at the bottom inside the housing 1 and the rotary power member 6 drives the first reciprocating lead screw 7 to rotate. The first reciprocating lead screw 7 is distributed in the vertical direction and is in the same vertical plane as the second reciprocating lead screw 34. The first reciprocating lead screw 7 and the second reciprocating lead screw 34 are rotationally connected through a gear set 10.

[0045] Specifically, the power assembly 37 further includes a ratchet 30. There are multiple groups of ratchets 30 which are respectively fixedly installed on the rotating shafts of the heat conduction plates 28. The ratchet 30 is engaged with the rack 31 fixedly installed on the partition plate 4. The rack 31 is parallel to the second reciprocating lead screw 34 and the end of the rack 31 close to the partition plate 4 is not provided with teeth. A fourth magnet 35 is fixedly installed on the rotating shaft of the heat conduction plate 28. The fourth magnet 35 is in sliding contact with the moving plate 27 and the heat conduction plate 28 is a magnetic material.

[0046] Specifically, the first reciprocating lead screw 7 drives the lifting frame 8 slidably installed on the inner wall of the housing 1 to move. Multiple groups of cooling fans 9 are fixedly installed on the lifting frame 8, and the positions of the cooling fans 9 correspond to the filter screens 5.

[0047] In actual application of this embodiment, the rotary power member 6 drives the first reciprocating lead screw 7 to move. The first reciprocating lead screw 7 drives the second reciprocating lead screw 34 to rotate through the gear set 10. The second reciprocating lead screw 34 drives the moving plate 27 to move away from the partition plate 4, so that the heat sink 29 moves out of the through groove 11. When the heat sink 29 completely moves out of the through groove 11, at this time, the ratchet wheel 30 contacts the teeth on the rack 31. As the moving plate 27 continues to move, under the action of the ratchet wheel 30 and the rack 31, the heat conduction plate 28 rotates. When the heat conduction plate 28 rotates 180 degrees, the moving plate 27 reaches the end of the second reciprocating lead screw 34. At this time, the moving plate 27 will reset. When the moving plate 27 resets, the ratchet wheel 30 will rotate idly, and the heat conduction plate 28 is further fixed by the fourth magnet 35 to ensure the stability of the heat conduction plate 28. When the heat conduction plate 28 contacts the partition plate 4 again, the rotary power member 6 stops operating, so as to realize the interchange of the positions of the heat sinks 29 on both sides of the heat conduction plate 28;

[0048] When the first reciprocating lead screw 7 rotates, it drives the lifting frame 8 to move, and then drives the radiator fan 9 to move. The radiator fan 9 blows the air in the area formed by the partition plate 4 and the inner wall of the housing 1 outward. The outside air will also enter this area through the filter screen 5, realizing the circulating flow of air, improving the cooling speed of the relatively high-temperature heat sink 29 removed from the closing plate 15, further improving the cooling efficiency in the housing 1. At the same time, the air flowing outward through the filter screen 5 can clean the impurities adhered to the outside of the filter screen 5, and cooperate with the up-and-down movement of the radiator fan 9 to realize the comprehensive cleaning of the filter screen 5, so as to ensure the cleanliness of the filter screen 5, ensure the air intake volume of the air entering the housing 1, reduce the probability of dust entering the housing 1, and is beneficial to the heat dissipation of the housing 1.

[0049] In an example of the present invention, the rotary power member 6 is a motor. Of course, it can also be other components such as a hydraulic motor that can output rotary power. The motor drives the first reciprocating lead screw 7 and the second reciprocating lead screw 34 to rotate. The gear set 10 is a bevel gear set. The bevel gear set is provided with two bevel gears, and the two bevel gears are respectively fixedly installed on the first reciprocating lead screw 7 and the second reciprocating lead screw 34. The rotation connection between the first reciprocating lead screw 7 and the second reciprocating lead screw 34 is realized through the two meshing bevel gears.

[0050] As Figures 4 - 10 shown, a highly efficient heat dissipation type ring network box structure provided by the present invention is shown. A first cover plate 13 is slidably installed in the closing plate 15. The first cover plate 13 is installed through a plurality of guide rods 12. When the first cover plate 13 contacts the partition plate 4, it closes the through groove 11 and there is a gap between the side edge of the first cover plate 13 and the closing plate 15. The first cover plate 13 is made of magnetic material and the partition plate 4 is fixedly installed with first magnets 14 for adsorbing and fixing the first cover plate 13 at both ends of the through groove 11.

[0051] Specifically, support rods 32 located on both sides of the heat dissipation fins 29 are fixedly installed on both side surfaces of the heat conduction plate 28. A third magnet 33 is fixedly installed at the end of the support rod 32. When the third magnet 33 extends into the through groove 11, it adsorbs the first cover plate 13.

[0052] Specifically, a first communication chamber 19 and a second communication chamber 21 are fixedly installed on the surface of the partition plate 4 away from the partition net plate 3. The first communication chamber 19 communicates with the area enclosed by the closing plate 15 through multiple suction pipes 20. The second communication chamber 21 communicates with the area enclosed by the closing plate 15 through multiple air supply pipes 22. The suction pipes 20 and the air supply pipes 22 are connected to both ends of the closing plate 15. An air pump 23 is fixedly installed on the partition plate 4. The air pump 23 communicates with the first communication chamber 19 and the second communication chamber 21 through a first communication pipe 24 and a second communication pipe 25 respectively. A filter 26 is fixedly installed on the second communication pipe 25.

[0053] In actual application of this embodiment, when the heat conduction plate 28 moves towards the partition plate 4, the third magnet 33 first contacts and pushes the first cover plate 13 to move, causing the first cover plate 13 to disengage from the fixation with the first magnet 14. After the third magnet 33 contacts the first cover plate 13, it will adsorb and fix the first cover plate 13. When replacing the heat dissipation fins 29 and entering the closing plate 15 later, the heat conduction plate 28 moves in the direction away from the partition plate 4. At this time, the third magnet 33 will drive the first cover plate 13 to move along until the first cover plate 13 contacts the partition plate 4. Subsequently, the third magnet 33 disengages from the first cover plate 13. At this time, the first cover plate 13 is fixed by the first magnet 14. The through groove 11 is closed from inside the closing plate 15 by the first cover plate 13, thereby avoiding the through groove 11 being always in an open state during the replacement of the heat dissipation fins 29, reducing the probability of impurities entering the closing plate 15 through the through groove 11 during the replacement of the heat dissipation fins 29, and reducing the efficiency of heat dissipation caused by dust adhering to the heat dissipation fins 29 and the internal equipment of the housing 1, and further improving the heat dissipation efficiency;

[0054] During normal use, air in the first communication chamber 19 is extracted by an air pump 23 and then conveyed into the second communication chamber 21. The air in the second communication chamber 21 returns to the inside of the closing plate 15 through an air delivery pipe 22. Meanwhile, the air inside the closing plate 15 can enter the first communication chamber 19 through an air extraction pipe 20, thereby realizing the circulating flow of the air inside the housing 1 and further improving the heat dissipation capacity of the equipment inside the housing 1. Within a set time after the heat sink 29 is replaced, at this time, the second cover plate 16 is in contact with the closing plate 15, and the area surrounded by the closing plate 15 is in a closed state. The air in the area surrounded by the closing plate 15 circulates through the air pump 23. During the circulation process, impurities carried in the air are filtered by a filter 26. After reaching the set time, the second cover plate 16 leaves the closing plate 15, enabling the air in the area surrounded by the closing plate 15 to re-participate in the circulating flow of the air inside the housing 1. It is possible to perform separate circulating filtration on the gas that is about to participate in the air circulation inside the housing 1 in the area surrounded by the closing plate 15, further reducing the probability of impurities entering the inside of the housing 1 and adhering to the heat sink 29, and further improving the heat dissipation efficiency.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.

[0056] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
