Description

Technical Field

[0001] The present invention relates to the technical field of ring main units, and particularly to a leakage-proof integrated primary and secondary ring main unit. Background Art

[0002] The integrated primary and secondary ring main unit is an intelligent power distribution device that deeply integrates primary equipment (high-voltage main circuit electrical components) and secondary equipment (control, protection, monitoring, and communication units) in the power system. It is mainly used in the ring network power supply scenario of the 10kV distribution network to achieve power distribution, fault isolation, and automation management.

[0003] When the ring main unit is used in the rainy season or high-humidity environment, since the internal equipment of the ring main unit needs to dissipate heat, a large number of heat dissipation holes are usually opened on the outer wall of the ring main unit. As a result, a large amount of moisture will penetrate into the ring main unit through the heat dissipation holes in the humid environment. And when there is a temperature difference between day and night, the moisture in the cabinet will condense into water droplets, accumulate at the bottom of the cabinet, and the accumulated water will reverse osmosis into the equipment through the unblocked cable holes, accelerating the electrochemical corrosion of metal components. At the same time, the high-humidity operating environment inside the ring main unit will also cause the circuit board to get damp, triggering false alarms or false actions of automation modules (such as current acquisition units). Sensors such as the front cabinet door detection module may misjudge the state of the earthing switch due to the interference of condensate penetration, threatening the operation and maintenance safety. Summary of the Invention

[0029] In summary, due to the adoption of the above technology of a primary-secondary integrated complete ring main cabinet with anti-leakage, the beneficial effects of the present invention are as follows:

[0030] 1. In this application, the moisture-absorbing cotton belt is wound and shaped by multiple roller shafts, so that the moisture-absorbing cotton belt can ensure the contact area with air in a narrow space. The roller shaft drives the moisture-absorbing cotton belt to rotate. The gas after the moisture-absorbing cotton belt absorbs and dries the relatively humid fresh air through the air inlet enters the ring main cabinet body, avoiding a large amount of moisture from leaking into the cabinet body. The part of the moisture-absorbing cotton belt with moisture rotates to one side of the air outlet, and the dry and high-temperature gas in the ring main cabinet body blows and dries the moisture-absorbing cotton belt to avoid the problem of the decline in dehumidification performance caused by the adsorption saturation of the moisture-absorbing cotton belt, ensuring the water absorption effect of the moisture-absorbing cotton belt and improving the overall anti-leakage effect of the cabinet body.

[0031] 2. In this application, the middle sealing plate is slid to drive the vertical sliding of the flow-cutting plate in the outer partition sandwich. The sliding of the flow-cutting plate changes the air flow paths of multiple air ducts in the annular network box body, realizing the switching adjustment between the first air flow state and the second air flow state, so as to meet the purpose of cooling and dehumidifying in the annular network box body under different requirements.

[0032] 3. In this application, multiple roller shafts are used to wind the moisture-absorbing cotton belt into an "M" shape and an inverted "V" shape, realizing an increase in the contact area between the moisture-absorbing cotton belt and the air flow in a narrow space, thereby ensuring that the installation space in the annular network box body will not be compressed.

[0056] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solution of a leak-proof primary and secondary integrated complete ring network cabinet in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0057] As Figure 1 - Figure 15 shown, the present invention provides: a leak-proof primary and secondary integrated complete ring network cabinet, including a ring network cabinet body 10, and further including an air duct 20. The air duct 20 is fixed inside the cabinet body of the ring network cabinet 10, and both ends of the air duct 20 are respectively communicated with an air inlet 11 and an air outlet 12 opened at the upper end of the ring network cabinet 10. Then, a plurality of heat dissipation fans 13 are fixed on the side of the air outlet 12 away from the air duct 20 to exhaust air from the inside of the ring network cabinet 10, so that a negative pressure is formed inside the ring network cabinet 10, and the air flow enters through the air inlet 11 and is discharged through the air outlet 12 to realize heat exchange inside the ring network cabinet 10;

[0058] A plurality of inner partition plates 60 are fixed on the inner wall of the ring network cabinet body 10. The plurality of inner partition plates 60 divide the ring network cabinet body 10 into a plurality of installation chambers. Each installation chamber is used to install a set of primary and secondary integrated cabinets. Then, through the air vents opened on the side of the air duct 20 close to the installation chamber, a negative pressure is formed in each installation chamber when the air enters, so that each installation chamber can achieve effective heat dissipation (as Figure 12 shown);

[0059] A plurality of outer partition plates 40 are fixed inside the air duct 20 and are divided into a plurality of chambers by the plurality of outer partition plates 40. Each chamber corresponds to the installation chamber and the air vent (as Figure 7 shown);

[0060] An air flow path switching component 50 is sleeved on the air duct 20. The air flow path switching component 50 includes a sealing plate 51 slidably arranged on the lower surface of the air duct 20. The sealing plate 51 is provided with a plurality of corresponding holes adapted to the air vents. By sliding the sealing plate 51, the corresponding holes are driven to move, so as to realize the adjustment of the opening degree of the overlapping part between the air vent and the corresponding hole;

[0061] By opening inner through holes 631 on the inner partition plates 60 and fixing a plurality of baffles 53 on the sealing plate 51 on one side of the inner through holes 631, when the sealing plate 51 slides and the corresponding holes correspond to the air vents, the baffles 53 are far away from the inner partition plates 60, and at this time, the inner through holes 631 are opened, and the adjacent chambers are communicated (as Figure 3 、 Figure 7 shown);

[0062] A plurality of roller shafts 18 are rotatably arranged inside the air duct 20, and a moisture-absorbing cotton belt 30 with its head and tail fixed is wound around the plurality of roller shafts 18. The moisture-absorbing cotton belt 30 is wound and shaped by the plurality of roller shafts 18, so that the contact area between the moisture-absorbing cotton belt 30 and the air can be ensured even in a narrow space. Subsequently, the roller shafts 18 drive the moisture-absorbing cotton belt 30 to rotate. After the moisture-absorbing cotton belt 30 absorbs and dries the relatively humid fresh air through the air inlet 11, the dried gas enters the annular network box body 10, preventing a large amount of moisture from entering the box body. The part of the moisture-absorbing cotton belt 30 with moisture rotates to one side of the air outlet 12, and the dry and hot gas inside the annular network box body 10 blows and dries the moisture-absorbing cotton belt 30 to avoid the problem of reduced dehumidification performance caused by the saturation adsorption of the moisture-absorbing cotton belt 30, ensuring the water absorption effect of the moisture-absorbing cotton belt 30 and improving the overall anti-leakage effect of the box body;

[0063] When the sealing plate 51 slides and the opening degree of the overlapping part between the adjusting air outlet and the corresponding opening gradually increases, all the air outlets are opened. At the same time, when the baffle 53 moves away from the inner partition 60, the inner through hole 631 is opened, the flow-cutting plate 421 is lifted upward, the air duct above the outer partition 40 is cut off, and the air duct below is opened to form a second air flow state (as Figure 14 shown);

[0064] When the sliding sealing plate 51 is moved and the air outlet is gradually staggered from the corresponding opening, multiple air outlets and corresponding holes are blocked. At the same time, the flow-cutting plate 421 slides downward along the outer partition 40, and part of the air duct below the outer partition 40 is cut off. After the air duct above is opened, a first air flow state is formed (as Figure 12 shown)

[0065] Furthermore, by sliding the middle sealing plate 51 to drive the flow-cutting plate 421 in the interlayer of the outer partition 40 to slide vertically, the sliding of the flow-cutting plate 421 changes the air flow paths of multiple air ducts inside the annular network box body 10, realizing the switching adjustment between the first air flow state and the second air flow state to meet the purpose of cooling and dehumidifying the inside of the annular network box body 10 under different requirements.

[0066] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 shown, both ends of the roller shaft 18 are rotatably arranged on the inner wall of the air duct 20 through bearings to reduce the friction between the roller shaft 18 and the air duct 20 when the roller shaft 18 rotates. A plurality of roller shafts 18 are vertically arranged at both ends of the air duct 20 and are distributed in a staggered manner up and down, and a plurality of roller shafts 18 are horizontally arranged in the middle of the air duct 20 and are distributed in a staggered manner up and down;

[0067] As Figure 4As shown, the moisture-absorbing cotton belt 30 is wound around multiple vertically staggered rollers 18 to form an "M"-shaped primary moisture-absorbing part 31 with an opening facing the air inlet 11 and an "M"-shaped dehumidifying part 32 with an opening facing the air outlet 12. The moisture-absorbing cotton belt 30 is wound around multiple horizontally staggered rollers 18 to form an inverted "V"-shaped secondary moisture-absorbing part 33 with an opening facing the inner partition 60. By winding the moisture-absorbing cotton belt 30 into an "M" shape and an inverted "V" shape with multiple rollers 18, the contact area between the moisture-absorbing cotton belt 30 and the air flow is increased in a narrow space, thereby ensuring that the installation space inside the ring network box body 10 will not be compressed;

[0068] The primary moisture-absorbing part 31 is placed inside the air inlet 11, and the dehumidifying part 32 is placed inside the air outlet 12;

[0069] It should be noted that in order to prevent a large amount of dust particles from being carried into the ring network box body 10 by the rotating moisture-absorbing cotton belt 30, a filter element is installed at the front end of the air inlet 11 of the ring network box body 10 to intercept dust.

[0070] An air supply port 21 is opened on the lower surface of one end of the air duct 20 close to the air inlet 11. The air supply port 21 and the air inlet 11 are placed in the same cavity, so that after the outdoor fresh air passes through the air inlet 11 and is moisture-absorbed by the moisture-absorbing cotton belt 30, the dried fresh air enters the installation room directly below through the air supply port 21;

[0071] It should be noted that when the box door is closed, the outside of the outer partition 40 avoids the electrical components of the box door and abuts against them. At the same time, the part of the air duct 20 far from the side air return port 24 abuts against the box door, thereby ensuring that each installation room is isolated from each other after the box door is closed. A gap is reserved between the side wall of the air duct 20 close to the air outlet 12 and the box door, and side air return ports 24 symmetrically opened on one end side wall are adopted to avoid a large air resistance caused by the moisture-absorbing cotton belt 30 during downward air return in the form of side air return, so as to ensure the effective flow of the air speed in the installation room;

[0072] Such as Figure 6 、 Figure 13 As shown, a first air return port 22 and a second air return port 23 are also opened on the lower surface of the air duct 20. The first air return port 22 and the second air return port 23 correspond to the installation rooms far from the air inlet 11 and the air outlet 12 respectively;

[0073] Such as Figure 2 、 Figure 3 、 Figure 8As shown, a first corresponding hole 511 corresponding to the first air return opening 22 is formed in the sealing plate 51, and a second corresponding hole 512 corresponding to the second air return opening 23 is further formed in the sealing plate 51. The sealing plate 51 fits and slides on the lower surface of the air duct 20, and the adjustment of the coincidence degree between the first corresponding hole 511 and the first air return opening 22 and the coincidence degree between the second corresponding hole 512 and the second air return opening 23 is used to realize the adjustment of the opening and closing of the air outlet.

[0074] As Figure 10 , Figure 12 shown, a first outer partition plate 41, a second outer partition plate 42, and a third outer partition plate 43 are fixed inside the annular network box body 10, and the first outer partition plate 41, the second outer partition plate 42, and the third outer partition plate 43 divide the annular network box body 10 into a first installation chamber 14, a second installation chamber 15, a third installation chamber 16, and a fourth installation chamber 17. The air supply opening 21 is placed above the first installation chamber 14, the first air return opening 22 is placed above the second installation chamber 15, the second air return opening 23 is placed above the third installation chamber 16, and the side air return opening 24 is placed above the fourth installation chamber 17;

[0075] As Figure 10 , Figure 13 shown, the upper edges of the first outer partition plate 41 and the third outer partition plate 43 are attached to the air duct 20, the sealing plate 51 passes through the third outer partition plate 43, and a lower air duct 424 is reserved between the lower edges of the first outer partition plate 41, the second outer partition plate 42, and the third outer partition plate 43 and the bottom wall of the annular network box body 10, and an upper air duct 423 is reserved between the upper edge of the second outer partition plate 42 and the air duct 20;

[0076] The flow-cutting plate 421 is vertically inserted and slid in the sandwich of the second outer partition plate 42, and a plurality of tension springs are fixed between the lower edge of the flow-cutting plate 421 and the annular network box body 10. Therefore, when the flow-cutting plate 421 and the sealing plate 51 are connected by a plurality of traction ropes 422 and pulled upward, the tension springs are elastically stretched at this time to facilitate the reset of the flow-cutting plate 421;

[0077] When the sealing plate 51 slides in the direction of the air inlet 11, the first corresponding hole 511 corresponds to the first air return opening 22, the second corresponding hole 512 corresponds to the second air return opening 23, the air duct 20 returns air through the air return opening, the flow-cutting plate 421 slides upward and blocks the upper air duct 423, and all the lower air ducts 424 are opened. At this time, the air flow in the second installation chamber 15, the third installation chamber 16, and the fourth installation chamber 17 can flow from bottom to top through the bottom of the installation chamber, forming a second air flow state (as Figure 14 shown);

[0078] When the sealing plate 51 slides towards the air outlet 12, the first corresponding hole 511 is staggered from the first air return opening 22, and the second corresponding hole 512 is staggered from the second air return opening 23. The cut-off flow plate 421 slides downward under the elastic contraction of the tension spring, and the lower air duct 424 of the second outer partition 42 is closed, while the upper air duct 423 is opened. At this time, the air duct 20 only supplies air to the box body through the air supply opening 21, and then returns the air through the side air return opening 24.

[0079] The isolation of the air flow by the outer partition 40 enables the air flow to pass through the first installation chamber 14 from top to bottom, then enter the second installation chamber 15 from bottom to top through the lower air duct 424, then enter the third installation chamber 16 from top to bottom through the upper air duct 423, and finally enter the fourth installation chamber 17 from bottom to top through the lower air duct 424, causing the entire air flow to flow in an S shape to form the first air flow state (as Figure 12 shown).

[0080] As Figure 2 、 Figure 7 shown, a first inner partition 61, a second inner partition 62, and a third inner partition 63 are fixed inside the air duct 20. The first inner partition 61, the second inner partition 62, and the third inner partition 63 divide the air duct 20 into four chambers. An inner through hole 631 is opened on the second inner partition 62 and the third inner partition 63. Baffles 53 are provided on the same side of the second inner partition 62 and the third inner partition 63. The two baffles 53 are fixed by a connecting rod 54 passing through the second inner partition 62. A sleeve 52 fixed to the sealing plate 51 is sleeved on the air duct 20;

[0081] Through a servo electric cylinder 55 fixed to the lower surface of the air duct 20, the piston rod of the servo electric cylinder 55 is fixedly connected to the sleeve 52. The telescopic movement of the piston rod pushes the sleeve 52 to slide along the air duct 20, driving the sealing plate 51 to slide. Under the fixed connection of the connecting rod 54, the two baffles 53 are driven to slide synchronously, and thus the opening and closing of the inner through hole 631 are adjusted through the sliding of the baffles 53;

[0082] To ensure the normal circulating rotation of the moisture-absorbing cotton belt 30 inside the air duct 20, a partial cotton belt below the moisture-absorbing cotton belt 30 passes through the first inner partition 61, the second inner partition 62, and the third inner partition 63.

[0083] As Figure 6 、 Figure 8As shown, in order to avoid large differences in the air flow rates of the four installation chambers in the second air flow state of the air flow, the diameter of the first air return opening 22 is larger than that of the second air return opening 23, and the diameter of the second air return opening 23 is larger than that of the side air return opening 24 after being blocked by the sleeve 52. Therefore, when the first corresponding hole 511 corresponds to the first air return opening 22 and the second corresponding hole 512 corresponds to the second air return opening 23, the side wall of the sleeve 52 will also block part of the side air return opening 24 to reduce the diameter of the side air return opening 24, so as to ensure that a sufficient amount of air flow can enter the air duct 20 at the air outlet end far from the heat dissipation fan 13.

[0084] As Figure 7 shown, the upper edges of the first inner partition 61, the second inner partition 62, and the third inner partition 63 are fixedly connected to the isolation plate 64. The isolation plate 64 and the inner wall of the air duct 20 form a waterproof cavity 641. Part of the upper part of the moisture-absorbing cotton belt 30 penetrates into the waterproof cavity 641. Therefore, when the moisture-absorbing cotton belt 30 rotates clockwise, the moisture-absorbing cotton belt 30 after absorbing water enters the cavity through the waterproof cavity 641. Through the isolation of the waterproof cavity 641, the evaporated moisture is prevented from entering the cavity of the dried moisture-absorbing cotton belt 30, thus achieving the effect of separating dry and wet.

[0085] As Figure 9 shown, the servo motor 70 is fixed at one end of the air duct 20 close to the air inlet 11, and the output shaft of the servo motor 70 drives one of the roller shafts 18 to rotate through the cooperation of a synchronous pulley and a synchronous belt. The surface of the roller shaft 18 is provided with anti-slip lines to increase the friction coefficient with the moisture-absorbing cotton belt 30. Then, the roller shaft 18 is driven to rotate by the energized operation of the servo motor 70, and the roller shaft 18 drives the moisture-absorbing cotton belt 30 to rotate cyclically under the action of friction to achieve the purpose of dry-wet replacement.

[0086] As Figure 2 shown, a clamping plate 25 is fixed on the lower surface of the air duct 20, and the sealing plate 51 is slidably inserted on the clamping plate 25. The guiding of the clamping plate 25 is used to improve the stability of the sealing plate 51, prevent the sealing plate 51 from bending downward, and ensure the fitting degree between the sealing plate 51 and the air duct 20.

[0087] As Figure 2 、 Figure 13 、 Figure 15 shown, a redirecting frame 26 is also fixed on the lower surface of the air duct 20. The redirecting frame 26 is placed above the cross-flow plate 421. A plurality of traction ropes 422 are wound around the redirecting frame 26 to form an L-shaped structure. Then, through the traction of the traction ropes 422, the cross-flow plate 421 can be vertically pulled upward, so that the cross-flow plate 421 can be lifted upward more smoothly.

[0088] As Figure 5As shown, in order to avoid problems such as intermediate breakage or slack of the moisture-absorbing cotton belt 30 during cyclic rotation, which may cause the roller 18 to slip, the moisture-absorbing cotton belt 30 is adhered to the outer surface of the conveyor belt 34 with mesh holes. Then, through the cooperation of the conveyor belt 34, the normal cyclic rotation of the moisture-absorbing cotton belt 30 is ensured. At the same time, to ensure the tension, at least one roller 18 is a tensioning roller.

[0089] Working principle: In the first flow state of the air flow taking Figure 12 ... as an example, the output shaft of the servo motor 70 drives the roller 18 to rotate, and the roller 18 drives the moisture-absorbing cotton belt 30 to rotate clockwise. The part of the moisture-absorbing cotton belt 30 placed in the waterproof cavity 641 is the moisture-absorbing part during the cycle, and the moisture-absorbing cotton belt 30 in the lower part of the waterproof cavity 641 is the dried part after drying during the cycle;

[0090] In this state, the first corresponding hole 511 and the first air return port 22, and the second corresponding hole 512 and the second air return port 23 are staggered and blocked. At the same time, the flow-cutting plate 421 descends to block the lower air duct 424, and the upper air duct 423 is opened;

[0091] Start the cooling fan 13 and direct the air flow towards the outside of the annular network box 10. The inside of the annular network box 10 is in a negative pressure state. Outdoor fresh air enters the air duct 20 through the air inlet 11, and then passes through the first moisture-absorbing part 31 for moisture absorption and drying. The dried fresh air enters the first installation chamber 14 through the air supply port 21. The upper air duct 423 and the two lower air ducts 424 below are arranged in a staggered manner, so that the fresh air passes through the first installation chamber 14, the second installation chamber 15, the third installation chamber 16, and the fourth installation chamber 17 in an S-shaped manner, and exchanges heat with the inside of the installation chamber during the flowing process;

[0092] Subsequently, the dried and heat-carrying fresh air is inhaled into the air duct 20 again through the side air return port 24, and flows from left to right through the dehumidifying part 32 to dry the moisture carried by the dehumidifying part 32. The separated moisture is discharged through the cooling fan 13; the dried moisture-absorbing cotton belt 30 is cyclically rotated to the side of the air inlet 11 through cyclic rotation, and the moisture-absorbing cotton belt 30 with moisture rotates to the air outlet 12 and is dried by the dried and high-temperature fresh air for dehydration treatment.

[0093] The piston rod of the servo electric cylinder 55 is pushed to slide the sleeve 52 to the left, and the sealing plate 51 slides along the air duct 20. The first corresponding hole 511 corresponds to the first air return port 22, the second corresponding hole 512 corresponds to the second air return port 23, the sleeve 52 blocks part of the side air return port 24, and at the same time, the baffle 53 is driven by the connecting rod 54 to move away from the second inner partition 62 and the third inner partition 63, and the inner through hole 631 communicates with the first air return port 22 and the second air return port 23;

[0094] Meanwhile, the sliding sealing plate 51 lifts the tangential flow plate 421 upward through the towing rope 422, and the lower edges of the first outer partition plate 41, the second outer partition plate 42, and the third outer partition plate 43 form a lower air duct 424 with the bottom wall of the annular network box body 10, switching the air flow path in the annular network box body 10 into a second air flow state;

[0095] The heat dissipation fan 13 operates and the servo motor 70 stops. The air duct 20 is in negative pressure. Outdoor fresh air enters the air duct 20 through the air inlet 11, is dehumidified and dried by the primary dehumidification part 31, then enters the first installation chamber 14, and then is shunted through the lower air duct 424. The dried fresh air is divided into three parts. One part passes through the second installation chamber 15, flows into the air duct 20 from bottom to top through the first air return port 22, and is dehumidified twice by the inverted V-shaped secondary dehumidification part 32. One part passes through the third installation chamber 16, flows into the air duct 20 from bottom to top through the second air return port 23, and is dehumidified twice by the inverted V-shaped secondary dehumidification part 32. Finally, after mixing through the inner through hole 631, it is dehumidified for the third time by the already dehumidified dehumidification part 32, so as to quickly dehumidify the inside of the annular network box body 10.

[0096] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical idea of the present invention, makes equivalent replacements or changes to an anti-leakage primary-secondary integrated complete set of ring network boxes, and should be covered by the protection scope of the present invention.
