Description

Technical Field

[0001] The invention relates to the technical field of ring network boxes, and in particular to a primary and secondary fused complete ring network box with a dust removal function. Background Art

[0002] The ring main unit with integrated primary and secondary functions is an intelligent power equipment that integrates power distribution, protection, control and automation functions. Its core design concept is to highly integrate traditional primary equipment (such as ring main unit, mutual inductor, etc.) with secondary equipment (such as measurement and control unit, protection device, etc.) to form a standardized and modular whole, so as to achieve the integrated goal of power distribution, status monitoring, fault handling and remote control.

[0003] The integrated primary and secondary ring network boxes are often used in urban power grids, industrial parks, large buildings and other places. The environmental conditions in these places may be more complex and the dust pollution is more serious. Dust accumulation may cause poor heat dissipation of equipment, reduced insulation performance, and even cause short circuit and other faults, affecting the safe and stable operation of the power grid. The installation of dust removal equipment can ensure that the ring network box can maintain stable operation in complex environments, reduce faults and power outages caused by environmental factors, help reduce equipment wear and failure rate, and extend the service life of the equipment;

[0004] In actual use, when the air humidity is high, condensation in the ring network box may cause a short circuit between the two secondary wires on the terminal block. If it happens to be a switch trip circuit, it will immediately cause the switch to malfunction and cause a power outage. Therefore, a hydrophobic filter bag can be selected to block water molecules in the air. However, after the dust particles come into contact with water molecules, their surface easily absorbs moisture and forms a moist dust layer. This moist dust layer is not easily captured by the dust collector and is easy to clog the filter bag of the dust collector, affecting normal ventilation and dust removal effects. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that while the hydrophobic filter bag blocks the water molecules in the air, the dust easily absorbs moisture and forms a moist dust layer, and this moist dust layer is not easily captured by the dust collector and easily clogs the filter bag of the dust collector, affecting the normal ventilation and dust removal effect.

[0041] In summary, due to the use of the above-mentioned technology, a one- and two-stage fusion ring network box with dust removal function has the following beneficial effects:

[0042] 1. Through the dust removal mechanism, after the unfiltered air is introduced into the air inlet through the air inlet, the entrained larger dust particles and debris can be intercepted by the air inlet and collected in the dust collecting chamber arranged at the bottom of the shell. The inner wall of the dust collecting chamber is set to a cone to guide the dust particles and debris to concentrate. At the same time, the air enters the filter cylinder through the opening at the bottom of the filter cylinder, and enters the hydrophobic filter through the opening at the bottom of the lower connecting plate. Under the interception of the hydrophobic filter, the dust and moisture in the air are blocked by the hydrophobic filter. Under the action of gravity, the dust and water are separated from the hydrophobic filter and enter the dust collecting chamber. At this time, the dust-free dry air can pass through the hydrophobic filter and be discharged from the opening at the top of the filter cylinder. The air is led out of the shell through the air outlet, and the dust removal and dehumidification of the air are completed;

[0043] 2. Through the torsion mechanism, when the sleeve is pressed down and descends under the action of external force, the end of the sleeve contacts and squeezes the first spring, and the first spring undergoes elastic deformation. When the thrust that presses the sleeve down dissipates, the elastic deformation of the first spring is restored and a thrust is generated to push the lower connecting plate to rise and rotate. The lower connecting plate cooperates with the upper connecting plate to twist the hydrophobic filter screen. When the hydrophobic filter screen is twisted, it will produce an extrusion effect on the wet dust layer. This extrusion helps to remove the moisture therein and weaken the binding force between the dust particles. At the same time, twisting the hydrophobic filter screen will also cause the dust layer to be subjected to shear force. When the force is greater than the binding force between the dust particles or between the dust particles and the hydrophobic filter screen, the dust layer will be peeled off and fall off from the surface of the filter bag. The greater the deformation of the hydrophobic filter screen, the easier it is for the dust layer attached to the hydrophobic filter screen to fall off. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] 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 one- and two-fold fusion ring network box with a dust removal function. 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.

[0071] In order to solve the problem that the hydrophobic filter bag blocks the water molecules in the air, while the dust easily absorbs moisture and forms a wet dust layer, which is not easily captured by the dust collector and easily blocks the filter bag of the dust collector, affecting the normal ventilation and dust removal effect, the present invention proposes a one-two fusion set of ring mesh boxes with dust removal function, such as Figure 1 - Fig.18 As shown:

[0072] It includes a ring network box body 11 and a cooling fan 12 installed on the ring network box body 11, and an air supply mechanism 20 is installed on the cooling fan 12. The air supply mechanism 20 includes a shell 21 arranged in the ring network box body 11 and a cover 22 installed on the shell 21 and connected to the cooling fan 12. The cover 22 is provided with an air inlet 221 and an air outlet 222. When the cooling fan 12 is started, air is sucked in, so that the air enters the shell 21 through the air inlet 221, and after filtering the moisture and dust in the air, the air is introduced into the ring network box body 11 through the air outlet 222;

[0073] In order to be able to filter out moisture and dust, such as Figure 3 and Figure 7 As shown, a dust removal mechanism 30 is provided in the housing 21, and the dust removal mechanism 30 includes a filter cartridge 32 provided at the air outlet 222 and a filter 33 provided in the filter cartridge 32, and the filter 33 includes a lower connecting plate 331 movably installed in the filter cartridge 32 and an upper connecting plate 332 fixedly installed, and an annular hydrophobic filter screen 334 is provided at the edges of the lower connecting plate 331 and the upper connecting plate 332 to block the wet dust layer, and the lower connecting plate 331 and the upper connecting plate 332 are connected by a rotating telescopic rod 333;

[0074] After the unfiltered air is introduced into the air intake cylinder 31 through the air inlet 221, the larger dust particles and debris entrained can be intercepted by the air intake cylinder 31 and collected in the dust collecting chamber 211 arranged at the bottom of the shell 21. The inner wall of the dust collecting chamber 211 is arranged to be conical to guide the dust particles and debris to concentrate. At the same time, the air enters the filter cylinder 32 through the opening at the bottom of the filter cylinder 32, and enters the hydrophobic filter 334 through the opening at the bottom of the lower connecting plate 331. Under the interception of the hydrophobic filter 334, the dust and moisture in the air are blocked by the hydrophobic filter 334. Under the action of gravity, the dust and water are separated from the hydrophobic filter 334 and enter the dust collecting chamber 211. At this time, dust-free dry air can pass through the hydrophobic filter 334 and be discharged from the opening at the top of the filter cylinder 32. The air is exported from the shell 21 through the air outlet 222, and the dust removal and dehumidification of the air are completed.

[0075] Furthermore, in order to increase the retention time of air in the filter cartridge 32 and improve the filtering effect of the filter 33, as shown in FIG. Figure 4 and Fig.18 As shown, the dust removal mechanism 30 also includes an air intake cylinder 31 disposed in the housing 21 and connected to the air intake port 221. The air intake cylinder 31 has an opening at the bottom and is cylindrical with the filter cylinder 32. The inner diameter of the air intake cylinder 31 is smaller than that of the filter cylinder 32.

[0076] A closing plate 34 is provided in the housing 21 to fill the gap between the air inlet cylinder 31 and the filter cylinder 32;

[0077] Through this design, after the air is discharged from the air intake cylinder 31, it can only enter the filter cylinder 32 under the obstruction of the closing plate 34, and because the opening of the filter cylinder 32 is larger than the opening of the air intake cylinder 31, and the size of the opening will directly affect the wind speed at the opening, therefore, a larger opening will slow down the flow rate of air when it flows through. At the same time, because the same volume of air can flow out over a larger opening area, a slower flow rate is produced, and the amount of air flowing through per unit time is increased. Therefore, compared with the setting method in which the diameters of the air intake cylinder 31 and the filter cylinder 32 are the same, the setting method in which the diameter of the filter cylinder 32 is larger and the diameter of the air intake cylinder 31 is smaller, can make the air pass through the air intake cylinder 31 quickly, and more air enters the filter cylinder 32 and can be retained longer.

[0078] In order to remove the wet dust layer formed by the mixture of dust and water in the hydrophobic filter 334, a twisting mechanism 40 is provided at the bottom of the filter cartridge 32. Figure 8 , Figure 10-13 As shown, the torsion mechanism 40 includes a rotatable and ascending mounting plate 41 mounted on the bottom of the lower connecting plate 331;

[0079] The torsion mechanism 40 also includes a base 44 installed at the bottom of the filter cartridge 32 and a sleeve 42 rotatably connected to the mounting plate 41. A first spring 45 is installed in the middle of the base 44 and is in contact with the sleeve 42. When the sleeve 42 is pressed down and descends under the action of an external force, the end of the sleeve 42 contacts and squeezes the first spring 45, and the first spring 45 is elastically deformed. When the thrust that presses the sleeve 42 down dissipates, the elastic deformation of the first spring 45 is restored and a thrust is generated to push the lower connecting plate 331 up and rotate. The lower connecting plate 331 cooperates with the upper The connecting plate 332 twists the hydrophobic filter 334. When the hydrophobic filter 334 is twisted, it will squeeze the wet dust layer. This squeezing helps to remove the moisture in the dust layer, so that the binding force between the dust particles is weakened. At the same time, the twisting of the hydrophobic filter 334 will also cause the dust layer to be subjected to shear force. When the force is greater than the binding force between the dust particles or between the dust particles and the hydrophobic filter 334, the dust layer will be peeled off from the surface of the filter bag and fall off. The greater the deformation of the hydrophobic filter 334, the easier it is for the dust layer attached to the hydrophobic filter 334 to fall off.

[0080] Therefore, in order to enable the hydrophobic filter 334 to increase the deformation amount by rotating, such as Fig.11 and Fig.12 As shown, the torsion mechanism 40 further includes a guide 43 mounted on the lower connecting plate 331 and a guide groove 46 provided on the inner wall of the filter cartridge 32. The guide 43 includes a mounting seat 431 connected to the bottom of the lower connecting plate 331, a ball mounting cavity 432 mounted on the mounting seat 431, and a ball 433 embedded in the ball mounting cavity 432. The ball 433 is in rolling contact with the guide groove 46.

[0081] In the process of the mounting plate 41 pushing the lower connecting plate 331 to rise, the mounting seat 431 will also drive the ball mounting cavity 432 to move in the guide groove 46, and the ball 433 embedded in the ball mounting cavity 432 will roll in the guide groove 46. Under the guidance of the guide groove 46, the mounting plate 41 can rise and rotate along the trajectory of the guide groove 46. Since the upper connecting plate 332 is fixed, the lower connecting plate 331 can rotate while being restricted and guided by the rotating telescopic rod 333, and at the same time, it can shrink the distance from the upper connecting plate 332 by rising, thereby realizing the twisting of the hydrophobic filter screen 334, and the deformation of the hydrophobic filter screen 334 is increased.

[0082] In order to enable the sleeve 42 to be pressed downward by an external force, the base 44 includes a positioning seat 441 detachably mounted on the bottom of the filter cartridge 32 and a spring mounting groove 443 mounted on the positioning seat 441, a water storage cavity 442 is arranged on the outer edge of the spring mounting groove 443, and a mounting ring 444 is arranged between the water storage cavity 442 and the spring mounting groove 443;

[0083] The bottom of the first spring 45 is installed in the middle of the spring installation groove 443;

[0084] The height of the water storage chamber 442 is lower than the mounting ring 444 and a drainage groove is provided on the water storage chamber 442;

[0085] The base 44 is provided with a plurality of buckle mechanisms 50, which include a plurality of first slide grooves 51 provided on the water storage chamber 442 and an annular buckle groove 56 provided on the sleeve 42, and a rotating shaft 52 is slidably embedded in the first slide groove 51;

[0086] The surface of the rotating shaft 52 is sleeved with a mounting frame 53, and the end of the mounting frame 53 is mounted with a hook 54 that abuts against the slot 56 and can only rotate toward the side close to the rotating shaft 52. After the hook 54 and the slot 56 abut against each other, the rotating shaft 52 slides in the first sliding groove 51 to pull the sleeve 42 down, and retracts the distance between the sleeve 42 and the spring mounting groove 443 to squeeze the first spring 45.

[0087] A pressing plate 55 is installed on the other side of the mounting frame 53. Pressing the pressing plate 55 downward causes the mounting frame 53 to rotate around the rotating shaft 52 to release the contact between the hook 54 and the slot 56.

[0088] Torsion springs are provided in both the mounting frame 53 and the hook 54;

[0089] like Figure 8 As shown, after a wet dust layer is formed in the hydrophobic filter screen 334, the overall weight of the hydrophobic filter screen 334 increases, and since the hydrophobic filter screen 334 is conical, the lower connecting plate 331 at the bottom falls after the weight increases, and the lower connecting plate 331 pushes the sleeve 42 to descend through the mounting plate 41 and abuts against the first spring 45. At the same time, the guide 43 drives the mounting plate 41 to reverse under the guidance of the guide groove 46, and the lower connecting plate 331 drives the hydrophobic filter screen 334 to reversely twist. When the sleeve 42 contacts the hook 54, it can push the hook 54 to rotate until it is separated from the hook 54. The torsion spring in the hook 54 causes the hook 54 to rotate toward one side of the rotating shaft 52 under the pressure of the sleeve 42 and then reset to a horizontal state. The hook 54 can be inserted into the slot 56, and the hook 54 can also cooperate with the slot 56 to clamp the sleeve 42 The sleeve 42 is restricted so that it no longer rotates with the mounting plate 41, and the connection between the mounting frame 53 and the sleeve 42 is completed. Under the restriction of the hook 54, the sleeve 42 cannot be bounced up by the first spring 45;

[0090] The mounting ring 444 is provided with an unlocking mechanism 60, which includes a second slide groove 61 provided on the spring mounting groove 443, a slide table 62 is slidably embedded in the second slide groove 61, and a second spring 63 is provided at the bottom of the slide table 62;

[0091] The slide 62 is provided with a bracket 64 and a guide plate 66 penetrating the second slide groove 61, the bracket 64 is provided with a pressure plate 65 in contact with the inner wall of the water storage chamber 442, and the mounting frame 53 is provided with a positioning pin 67 penetrating the guide plate 66;

[0092] When the guide plate 66 presses down the positioning pin 67, it pushes the rotating shaft 52 to slide in the first sliding groove 51, so that the hook 54 pulls the sleeve 42 downward;

[0093] like Fig. 9 As shown, through this design, the water intercepted by the hydrophobic filter 334 can be gathered in the chamber formed by the water storage chamber 442 and the pressure plate 65. As the amount of water increases, the pressure plate 65 gradually descends and pulls the slide 62 through the bracket 64. The slide 62 descends in the second slide groove 61 and squeezes the second spring 63 to make it elastically deformed. At the same time, the slide 62 pulls the mounting frame 53 downward through the guide plate 66 and the positioning pin 67, so that the mounting frame 53 cooperates with the hook 54 and the slot 56 to pull the sleeve 42 down. At the same time, the mounting frame 53 drives the rotating shaft 52 to descend under the restriction of the first slide groove 51 until the pressure plate 65 reaches the lowest point of the water storage chamber 442. At this time, the accumulated water stored in the water storage chamber 442 is discharged through the drainage groove at the bottom.

[0094] At the same time, the unlocking mechanism 60 further includes an abutment rod 68 and a telescopic rod 69 disposed on the mounting ring 444 , the abutment rod 68 penetrates the mounting ring 444 and the telescopic rod 69 penetrates the pressure plate 55 ;

[0095] One end of the abutment rod 68 located in the water storage chamber 442 is provided with a float 681. When water is stored in the water storage chamber 442, it floats up through the float 681. After the accumulated water in the water storage chamber 442 is discharged through the drainage groove at the bottom, the abutment rod 68 descends and abuts against the telescopic rod 69. Under the push of the abutment rod 68, the telescopic rod 69 contracts and presses down the pressure plate 55. The pressure plate 55 pushes the mounting frame 53 to rotate to release the abutment between the hook 54 and the slot 56. At the same time, the mounting frame 53 drives the positioning pin 67 to move along the inner wall track of the guide plate 66. The restriction of the sleeve 42 by the hook 54 and the slot 56 is released. At this time, the thrust generated by the elastic deformation recovery of the first spring 45 pushes the sleeve 42 to rise, thereby achieving the purpose of regularly twisting the hydrophobic filter 334 to remove the wet dust layer attached to the hydrophobic filter 334.

[0096] The torsion spring in the mounting frame 53 allows the mounting frame 53 to rotate around the rotating shaft 52 and then return to its original position;

[0097] When there is not enough water in the water storage chamber 442, the abutting rod 68 cannot float. At this time, the abutting rod 68 abuts against the telescopic rod 69 under the action of gravity and pushes the pressing plate 55, so that the pressing plate 55 drives the mounting frame 53 to maintain an offset state with the rotating shaft 52 as the axis. At this time, the hook 54 does not contact the sleeve 42 and the slot 56, so it will not interfere with the falling of the sleeve 42.

[0098] When water is stored in the water storage chamber 442 again and the abutment rod 68 floats, the abutment rod 68 no longer abuts against the telescopic rod 69 to limit the position of the pressure plate 55. At this time, the mounting frame 53 pulls the telescopic rod 69 to restore through the pressure plate 55, and the mounting frame 53 drives the hook 54 to snap into the slot 56.

[0099] like Figure 15-17 As shown, in order to prevent the internal accumulated water and debris from leaking when the cover body 22 is removed to clean the internal air inlet 221 and replace the filter 33, a closing mechanism 70 is provided between the cover body 22 and the air inlet cylinder 31 and the filter cylinder 32. The closing mechanism 70 includes a second grid net 76 provided in the air inlet cylinder 31 and a first grid net 71 provided in the filter cylinder 32. The second grid net 76 and the first grid net 71 are both provided with a countersunk hole 72. A movable rod 74 is movably embedded in the countersunk hole 72, and the movable rod 74 is connected to the countersunk hole 72 through a third spring 73.

[0100] A closed grid mesh 75 for closing the inlet and outlet of the shell 21 is installed at the top of the movable rod 74, and a push rod 77 is installed in the air inlet 221 and the air outlet 222. When the cover body 22 is combined with the shell 21, the push rod 77 pushes the closed grid mesh 75 to move, so that the closed grid mesh 75 enters the cavity of the air inlet cylinder 31 or the filter cylinder 32. The closed grid mesh 75 drives the movable rod 74 to move in the countersunk hole 72 and squeezes the third spring 73 to cause it to undergo elastic deformation. At this time, air enters through the closed grid mesh 75 in the air inlet cylinder 31, passes through the first grid mesh 71 to reach the air inlet cylinder 31, and the air in the filter cylinder 32 passes through the first grid mesh 71, and then is discharged from the filter cylinder 32 through the closed grid mesh 75. When the push rod 77 is removed from the closed grid mesh 75, the closed grid mesh 75 closes the openings at the top of the air inlet cylinder 31 and the filter cylinder 32 under the push of the elastic deformation recovery of the third spring 73.
