Description

Technical Field

[0001] The invention relates to the technical field of ring net boxes, and in particular to a leakage-proof primary and secondary fused complete ring net box. Background Art

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

[0003] When the ring network box is used in the rainy season or in a high humidity environment, a large number of heat dissipation holes are usually opened on the outer wall of the ring network box because the internal equipment of the ring network box needs to dissipate heat. In a humid environment, a large amount of moisture will penetrate into the ring network box through the heat dissipation holes. When there is a temperature difference between day and night, the moisture in the cabinet will condense into water droplets and accumulate at the bottom of the cabinet. The accumulated water will reversely permeate into the equipment through the unblocked cable holes, accelerating the electrochemical corrosion of metal parts. At the same time, the high humidity operating environment in the ring network box will also cause the circuit board to get damp, causing false alarms or malfunctions of the automation module (such as the current acquisition unit). Sensors such as the front cabinet door detection module may misjudge the state of the grounding switch due to interference from condensation penetration, threatening operation and maintenance safety. Summary of the invention

The hygroscopic cotton belt is driven to rotate by the rollers, and the hygroscopic cotton belt absorbs moisture from fresh air with high humidity through the air inlet, and the dried gas enters the ring network box to prevent a large amount of moisture from leaking into the box. The hygroscopic cotton belt with moisture is partially rotated to one side of the exhaust port, and the dry and high-temperature gas in the ring network box blows back to dry the hygroscopic cotton belt to avoid the problem of decreased dehumidification performance due to adsorption saturation of the hygroscopic cotton belt, thereby ensuring the water absorption effect of the hygroscopic cotton belt and improving the overall anti-leakage effect of the box.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a leakage-proof primary and secondary fusion ring mesh box. Obviously, the described embodiment is only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] like Figure 1 - Fig.15 As shown, the present invention provides: a leakage-proof primary and secondary fusion set of ring network boxes, including a ring network box body 10, and also including an air duct 20, the air duct 20 is fixed inside the ring network box body 10, and the two ends of the air duct 20 are respectively connected with the air inlet 11 and the air outlet 12 opened at the upper end of the ring network box body 10, and 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 box body 10 to the outside, so that negative pressure is formed inside the ring network box body 10, and the air flow enters through the air inlet 11 and is then discharged through the air outlet 12 to realize heat exchange in the ring network box body 10;

[0058] A plurality of inner partitions 60 are fixed to the inner wall of the ring network box 10, and the plurality of inner partitions 60 divide the ring network box 10 into a plurality of installation rooms, each of which is used to install a set of primary and secondary fusion cabinets, and then through the air duct 20, the air outlet is opened near the side of the installation room, and the air outlet forms a negative pressure in each installation room when the air enters, so that each installation room can achieve effective heat dissipation (such as Fig.12 shown);

[0059] A plurality of external baffles 40 are fixed inside the air duct 20, and the air duct 20 is divided into a plurality of chambers by the plurality of external baffles 40, each chamber corresponding to the installation room and the air outlet (such as Figure 7 shown);

[0060] The air duct 20 is sleeved with an airflow path switching assembly 50, which 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 outlets. The sliding of the sealing plate 51 drives the corresponding holes to move, thereby adjusting the opening and closing degree of the overlapping part of the air outlet and the corresponding holes.

[0061] By providing an inner through hole 631 on the inner partition 60, and fixing a plurality of baffles 53 on the sealing plate 51 and arranged on one side of the inner through hole 631, when the sealing plate 51 slides and the corresponding hole is in a corresponding state with the air outlet, the baffle 53 moves away from the inner partition 60, and the inner through hole 631 is opened at this time, and the adjacent chambers are connected (such as Figure 3 , Figure 7 shown);

[0062] A plurality of rollers 18 are rotatably arranged in the air duct 20, and a hygroscopic cotton belt 30 fixed at the head and tail is wound on the plurality of rollers 18. The hygroscopic cotton belt 30 is shaped by winding through the plurality of rollers 18, so that the hygroscopic cotton belt 30 can ensure the contact area with the air even in a narrow space. Then, the rollers 18 drive the hygroscopic cotton belt 30 to rotate, and the hygroscopic cotton belt 30 absorbs and dries the fresh air with high humidity through the air inlet 11, and the dry gas enters the ring network box 10 to prevent a large amount of moisture from entering the box. The hygroscopic cotton belt 30 with moisture is partially rotated to one side of the exhaust port 12, and the dry and high-temperature gas inside the ring network box 10 blows back and dries the hygroscopic cotton belt 30 to avoid the problem of decreased dehumidification performance caused by adsorption saturation of the hygroscopic cotton belt 30, thereby ensuring the water absorption effect of the hygroscopic cotton belt 30 and improving the overall anti-leakage effect of the box.

[0063] When the sealing plate 51 slides, the overlapped portion of the regulating air outlet and the corresponding outlet gradually increases, and all the air outlets are opened. At the same time, when the baffle plate 53 is away from the inner partition plate 60, the inner through hole 631 is opened, and the flow cutting plate 421 is lifted upward, the air duct above the outer partition plate 40 is cut off, and the air duct below is opened to form the second flow state of the airflow (such as Fig.14 shown);

[0064] When the sealing plate 51 is slid and the air outlets and the corresponding openings are gradually staggered, multiple air outlets and corresponding holes are blocked, and at the same time, the flow cutting plate 421 slides downward along the outer baffle 40, and the air passage below the outer baffle 40 is partially cut off, and the upper air passage is opened to form the first flow state of the airflow (such as Fig.12 shown)

[0065] Then, the sliding sealing plate 51 drives the cutting plate 421 in the interlayer of the outer partition 40 to slide vertically. The sliding of the cutting plate 421 changes the airflow path of multiple air ducts inside the ring network box 10, and realizes the switching adjustment of the first flow state and the second flow state of the airflow, so as to meet the purpose of cooling and dehumidifying the inside of the ring network box 10 under different needs.

[0066] like Figure 3 , Figure 4 , Figure 5 , Fig. 9 As 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. Both ends of the air duct 20 are vertically arranged with multiple roller shafts 18 staggered up and down, and the middle part of the air duct 20 is horizontally arranged with multiple roller shafts 18 staggered up and down;

[0067] like Figure 4As shown, the hygroscopic cotton belt 30 is wound by a plurality of rollers 18 that are vertically staggered to form an "M"-shaped primary hygroscopic portion 31 with an opening toward the air inlet 11 and an "M"-shaped dehumidification portion 32 with an opening toward the air outlet 12. The hygroscopic cotton belt 30 is wound by a plurality of rollers 18 that are horizontally staggered to form an inverted "V"-shaped secondary hygroscopic portion 33 with an opening toward the inner partition 60. The hygroscopic cotton belt 30 is wound into an "M" shape and an inverted "V" shape by a plurality of rollers 18, thereby increasing the contact area between the hygroscopic cotton belt 30 and the airflow in a narrow space, thereby ensuring that the installation space in the ring network box 10 will not be compressed.

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

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

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

[0071] It is worth noting that when the cabinet door is closed, the outer side of the outer partition 40 avoids the electrical components of the cabinet door and abuts against it, and at the same time, the part of the air duct 20 away from the side return air port 24 abuts against the cabinet door, thereby ensuring that each installation room is isolated from each other after the cabinet door is closed, and a gap is reserved between the side wall of the air duct 20 close to the exhaust port 12 and the cabinet door, and a side return air port 24 symmetrically opened on one end of the side wall is used to avoid the moisture-absorbing cotton belt 30 causing a large wind resistance during the lower return air in the form of side return air, thereby ensuring that the wind speed in the installation room can be effectively guaranteed;

[0072] like Figure 6 , Fig.13 As shown, the lower surface of the air duct 20 is also provided with a first return air port 22 and a second return air port 23, and the first return air port 22 and the second return air port 23 correspond to the installation rooms away from the air inlet 11 and the air outlet 12 respectively;

[0073] like Figure 2 , Figure 3 , Figure 8As shown, the sealing plate 51 is provided with a first corresponding hole 511 corresponding to the first return air port 22, and the sealing plate 51 is also provided with a second corresponding hole 512 corresponding to the second return air port 23. The sealing plate 51 slides on the lower surface of the air duct 20, and the opening and closing of the air port are adjusted by adjusting the overlap between the first corresponding hole 511 and the first return air port 22 and the overlap between the second corresponding hole 512 and the second return air port 23.

[0074] like Fig.10 , Fig.12 As shown, a first outer partition 41, a second outer partition 42, and a third outer partition 43 are fixed inside the ring network box 10, and the first outer partition 41, the second outer partition 42, and the third outer partition 43 divide the ring network box 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 port 21 is placed above the first installation chamber 14, the first return air port 22 is placed above the second installation chamber 15, the second return air port 23 is placed above the third installation chamber 16, and the side return air port 24 is placed above the fourth installation chamber 17;

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

[0076] The flow cutting plate 421 is vertically inserted into the interlayer 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 ring network box 10. Therefore, when the flow cutting plate 421 and the sealing plate 51 are connected and pulled upward by a plurality of traction ropes 422, the tension springs are elastically stretched to facilitate the reset of the flow cutting plate 421.

[0077] When the sealing plate 51 slides toward the direction of the air inlet 11, the first corresponding hole 511 corresponds to the first return air port 22, the second corresponding hole 512 corresponds to the second return air port 23, the air duct 20 returns air through the return air port, 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 airflow 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 flow state of the airflow (such as Fig.14 shown);

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

[0079] The airflow is isolated by the outer partition 40 so that the airflow passes through the first installation chamber 14 from top to bottom, then enters the second installation chamber 15 from bottom to top through the lower air duct 424, then enters the third installation chamber 16 from top to bottom through the upper air duct 423, and finally enters the fourth installation chamber 17 from bottom to top through the lower air duct 424, so that the entire airflow flows in an S shape to form the first flow state of the airflow (such as Fig.12 as shown).

[0080] like Figure 2 , Figure 7 As shown, a first inner partition 61, a second inner partition 62, and a third inner partition 63 are fixed in the air duct 20, and the first inner partition 61, the second inner partition 62, and the third inner partition 63 divide the air duct 20 into four chambers. The inner through hole 631 is opened on the second inner partition 62 and the third inner partition 63. The second inner partition 62 and the third inner partition 63 are both provided with a baffle 53 on the same side. The two baffles 53 are fixed by a connecting rod 54 that passes through the second inner partition 62. The air duct 20 is sleeved with a sleeve 52 fixed to the sealing plate 51;

[0081] The servo electric cylinder 55 is fixed on the lower surface of the air duct 20, and the piston rod of the servo electric cylinder 55 is fixedly connected to the sleeve 52. The extension and contraction of the piston rod pushes the sleeve 52 to slide along the air duct 20, and drives 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 then the inner through hole 631 is opened and closed by the sliding adjustment of the baffle 53.

[0082] In order to ensure that the moisture-absorbing cotton belt 30 circulates and rotates normally in the air duct 20 , a portion of the moisture-absorbing cotton belt below the moisture-absorbing cotton belt 30 passes through the first inner partition plate 61 , the second inner partition plate 62 , and the third inner partition plate 63 .

[0083] like Figure 6 , Figure 8As shown, in order to avoid a large difference in the air volume of the four installation rooms when the air flow is in the second flow state, the first return air outlet 22 is larger than the diameter of the second return air outlet 23, and the diameter of the second return air outlet 23 is larger than the diameter of the side return air outlet 24 after being blocked by the sleeve 52. Therefore, when the first corresponding hole 511 corresponds to the first return air outlet 22, and the second corresponding hole 512 corresponds to the second return air outlet 23, the side wall of the sleeve 52 will also block part of the side return air outlet 24 to reduce the diameter of the side return air outlet 24, thereby ensuring that the air outlet at one end away from the heat dissipation fan 13 can have sufficient airflow to enter the air duct 20.

[0084] like Figure 7 As shown, the upper edges of the first inner partition 61, the second inner partition 62, and the third inner partition 63 are fixed with an isolation plate 64, and the isolation plate 64 and the inner wall of the air duct 20 form a waterproof cavity 641. The upper part of the hygroscopic cotton belt 30 is partially inserted into the waterproof cavity 641. Therefore, when the hygroscopic cotton belt 30 rotates clockwise, the hygroscopic cotton belt 30 after absorbing water enters the cavity through the waterproof cavity 641. The isolation of the waterproof cavity 641 prevents evaporated moisture from entering the cavity of the dried hygroscopic cotton belt 30, thereby achieving a dry-wet separation effect.

[0085] like Fig. 9 As 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 rollers 18 to rotate through the cooperation of the synchronous pulley and the synchronous belt. The surface of the roller 18 has anti-slip grooves to increase the friction coefficient with the hygroscopic cotton belt 30, and then the roller 18 is driven to rotate by the power-on operation of the servo motor 70. Under the action of friction, the roller 18 drives the hygroscopic cotton belt 30 to circulate and achieve the purpose of dry-wet replacement.

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

[0087] like Figure 2 , Fig.13 , Fig.15 As shown, a redirecting frame 26 is also fixed to the lower surface of the air duct 20, and the redirecting frame 26 is placed above the cutting plate 421. A plurality of traction ropes 422 are wrapped around the redirecting frame 26 to form an L-shaped structure, and then the cutting plate 421 can be pulled vertically upward by the traction of the traction ropes 422, so that the cutting plate 421 can be lifted upward more smoothly.

[0088] like Figure 5As shown, in order to avoid the problem of the roller 18 slipping due to the middle breakage or relaxation of the hygroscopic cotton belt 30 during the circulation, the hygroscopic cotton belt 30 is adhered to the outer surface of the conveyor belt 34 with a mesh, and then the normal circulation of the hygroscopic cotton belt 30 is guaranteed through the cooperation of the conveyor belt 34. At the same time, in order to ensure the tension, at least one of the rollers 18 is a tensioning roller.

[0089] Working principle: Fig.12 In the first flow state of the airflow, the output shaft of the servo motor 70 drives the roller 18 to rotate, and the roller 18 drives the hygroscopic cotton belt 30 to rotate clockwise. The part of the hygroscopic cotton belt 30 placed in the waterproof cavity 641 is the hygroscopic part in the cycle, and the hygroscopic cotton belt 30 below the waterproof cavity 641 is the dry part after drying in the cycle;

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

[0091] The heat dissipation fan 13 is started and the wind direction is toward the outside of the ring network box 10. The inside of the ring network box 10 is in a negative pressure state. The outdoor fresh air enters the air duct 20 through the air inlet 11, and then passes through the primary moisture absorption 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 staggered, so that the fresh air is S-shaped and passes through the first installation chamber 14, the second installation chamber 15, the third installation chamber 16, and the fourth installation chamber 17 in turn, and performs heat exchange with the installation chamber during the flow;

[0092] Subsequently, the dry fresh air carrying heat is sucked into the air duct 20 again through the side return air port 24, and flows to the right through the left side of the dehumidifier 32 to dry the moisture carried by the dehumidifier 32, and the separated moisture is discharged through the heat dissipation fan 13; the dried hygroscopic cotton belt 30 is replaced to the side of the air inlet 11 through a circulating rotation, and the hygroscopic cotton belt 30 with moisture is rotated to the exhaust port 12 for air drying treatment with dry and high-temperature fresh air, so that the hygroscopic cotton belt 30 is dehydrated.

[0093] The piston rod of the servo electric cylinder 55 pushes the sleeve 52 to slide to the left, and the sealing plate 51 slides against the air duct 20. The first corresponding hole 511 corresponds to the first return air port 22, and the second corresponding hole 512 corresponds to the second return air port 23. The sleeve 52 partially blocks the side return air port 24. 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 is connected to the first return air port 22 and the second return air port 23.

[0094] At the same time, the sliding sealing plate 51 lifts the cutting plate 421 upwards through the traction rope 422, and the lower edges of the first outer baffle 41, the second outer baffle 42, and the third outer baffle 43 and the bottom wall of the ring network box 10 form a lower air duct 424, switching the airflow path in the ring network box 10 to the second flow state of the airflow;

[0095] The cooling fan 13 is running and the servo motor 70 is stopped, and there is a negative pressure in the air duct 20. The outdoor fresh air enters the air duct 20 through the air inlet 11, and is dehumidified and dried by the first-level moisture absorption part 31, and then enters the first installation chamber 14, and is then diverted through the downwind duct 424. The dry fresh air is divided into three parts, one part flows into the air duct 20 from bottom to top through the first return air port 22 through the second installation chamber 15, and is dehumidified for the second time through the inverted V-shaped second-level dehumidification part 32; the other part flows into the air duct 20 from bottom to top through the second return air port 23 through the third installation chamber 16, and is dehumidified for the second time through the inverted V-shaped second-level dehumidification part 32; finally, the mixed flow is carried out through the inner through hole 631, and then the dehumidified fresh air is dehumidified for the third time through the dehumidification part 32, so that the inside of the ring network box 10 can be quickly dehumidified.

[0096] The above description is only a preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacement or changes to the anti-leakage primary and secondary fused ring network box and its inventive concept according to the technology of the present invention, which should be covered within the protection scope of the present invention.
