Description

Technical Field

[0001] The invention relates to the technical field of dust prevention of distribution boxes, and in particular to an automatic exchange type dust prevention and filtering distribution box. Background Art

[0002] The automatic exchange dust filter distribution box is an advanced distribution equipment designed to provide more efficient dust protection and longer maintenance cycles. This distribution box keeps the internal environment clean by automatically exchanging dust filters, thereby extending the service life of electrical equipment and reducing maintenance workload.

[0003] The air outlet and air inlet of ordinary distribution boxes are usually fixed, which causes dust to easily accumulate in these areas. Not only does it require frequent cleaning or replacement of filters to maintain good ventilation, but the dust at the air outlet is difficult to completely remove, which can easily cause secondary pollution, affect the heat dissipation performance and overall life of the equipment, and increase maintenance costs and workload.

[0004] Based on the above situation, the present invention proposes an automatic exchange type dust-proof filtering distribution box. Summary of the invention

[0005] In order to overcome the disadvantage that dust at the ventilation opening of a distribution box is difficult to clean, the present invention provides an automatic exchange type dustproof filtering distribution box.

[0006] An automatic exchange type dust-proof filtering distribution box comprises a distribution box body, the distribution box body is rotatably connected with a box door, the distribution box body is equipped with fans symmetrically distributed along the distribution box body, the distribution box body is equipped with filter covers symmetrically distributed along the distribution box body, a filter plate is arranged on the side of the filter cover close to the inside of the distribution box body, the filter cover is slidably connected with a conversion frame, a collection bag is inserted at the bottom of the filter cover, a first spring is fixedly connected between the conversion frame and the adjacent filter cover, the filter cover is fixedly connected with an electromagnet, the conversion frame is fixedly connected with a first magnetic block, when power is on, the first magnetic block cooperates with the adjacent electromagnet through the magnetic force of attraction, the distribution box body is fixedly connected with a timer, and the timer is electrically connected with the fan through a control module.

[0007] In addition, it is particularly preferred that it also includes a collecting rack corresponding to the fan, the collecting rack is fixedly connected to the rotating shaft corresponding to the fan, the collecting rack is in contact with the adjacent filter plate, a collecting groove is opened in the middle of the collecting rack, a collecting plate is fixed in the filter cover, the collecting rack is rotatably connected to the adjacent collecting plate, the interior of the collecting plate is set as a cavity, and the collecting rack is communicated with the cavity of the collecting plate through the collecting groove.

[0008] In addition, it is particularly preferred that a side of the collecting rack close to the collecting trough is arranged as an inclined surface, and when the collecting rack rotates, the inclined surface is driven to rotate to scrape off the stubborn dust on the adjacent filter plate.

[0009] In addition, it is particularly preferred that it also includes a first baffle corresponding to the collection tray, the first baffle is rotatably connected to the corresponding collection tray, and a ring with a notch is fixedly connected to one side of the collection rack close to the adjacent collection tray, and the ring contacts the adjacent first baffle when rotating.

[0010] In addition, it is particularly preferred that a torsion spring corresponding to the first baffle is further included, and the torsion spring is fixed between the corresponding first baffle and the adjacent collecting tray.

[0011] In addition, it is particularly preferred that it also includes a second spring symmetrically distributed along the filter plate, the second spring is fixed between the filter plate and the distribution box body, the collection rack is fixed with a lever, the filter plate is fixed with a fixed column, and the lever is squeezed and matched with the adjacent fixed column when rotating.

[0012] In addition, it is particularly preferred that a fixing rod corresponding to the conversion frame is further included, the fixing rod is fixedly connected to the corresponding conversion frame, and the conversion frame is rotatably connected to a second baffle.

[0013] Furthermore, it is particularly preferred that the second baffle plate is configured as a lightweight plate.

[0014] In addition, it is particularly preferred that it also includes a second magnetic block corresponding to the filter cover, the second magnetic block is fixedly connected to the corresponding filter cover, the second baffle is fixedly connected to a third magnetic block, and the third magnetic block moves downward to cooperate with the adjacent second magnetic block through magnetic force.

[0015] In addition, it is particularly preferred that the third magnetic block cooperates with the adjacent second magnetic block through an attractive magnetic force.

[0016] The beneficial effect is: the timer of the present invention controls the fans on the left and right sides to start alternately for one hour through the control module, so that the gas is filtered from the filter plate on one side and enters the distribution box body. The filtered gas then blows the dust left on the filter plate on the other side in the previous round into the filter cover on that side, and finally blows it into the collection bag on that side. In this way, the device can not only filter dust alternately while maintaining exchange ventilation, but also clean and collect residual dust accumulated at the vents.

[0017] The present invention utilizes the inclined surface of the collection frame close to the collection slot to scrape off the stubborn dust on the adjacent filter plates, and then drops the dust into the collection bag on the same side through the duct of the collection plate, thereby strengthening the cleaning and collecting of the residual dust accumulated at the ventilation opening.

[0018] The present invention utilizes the blocking effect of the first baffle plate to cause dust to accumulate on the side of the first baffle plate close to the pipe, thereby enabling the dust to tilt and fall into the collection bag on the same side more easily and quickly.

[0019] The present invention utilizes the intermittent extrusion cooperation between the lever and the fixing column, so that the filter plate can filter and remove dust from the incoming air while also intermittently vibrating back and forth, further strengthening the cleaning of residual dust accumulated at the vent.

[0020] The present invention provides a second baffle to prevent the dust in the collection bag from flowing back from the bottom of the filter cover to the inside of the distribution box body under the action of external wind when the power is off, that is, when the air circulation is stopped.

[0021] The present invention utilizes that when the second baffle moves downward, it will drive the third magnetic block to move downward until it contacts the second magnetic block. Under the action of magnetic attraction, it can prevent the second baffle from being pushed back to its original position by the dust collected in the collection bag, causing the air on the starting side of the fan to be blocked by the returned second baffle, and air cannot enter, thereby preventing ventilation.

DETAILED DESCRIPTION

[0034] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Embodiment 1: An automatic exchange type dust filter distribution box, such as Figure 1-Figure 3 As shown, it includes a distribution box body 1, the front side of the distribution box body 1 is rotatably connected to a box door 2, the interior of the distribution box body 1 is equipped with fans 3 symmetrically distributed along the left and right sides of the distribution box body 1, the fans 3 connect the inside and outside of the distribution box body 1, the outside of the distribution box body 1 is equipped with filter covers symmetrically distributed along the left and right sides of the distribution box body 1, the filter cover 4 is provided with a filter plate 5 on one side close to the inside of the distribution box body 1, the filter cover 4 is slidably connected to a conversion frame 6 along the up and down directions, a collecting bag 7 is inserted at the bottom of the filter cover 4, a first spring 8 is fixedly connected between the conversion frame 6 and the adjacent filter cover 4, an electromagnet 9 is fixedly connected to the top of the filter cover 4, a first magnetic block 10 is fixedly connected to the top of the conversion frame 6, when power is on, the first magnetic block 10 cooperates with the adjacent electromagnet 9 through the magnetic force of attraction, a timer 101 is fixedly connected to the top of the distribution box body 1, and the timer 101 is electrically connected to the fan 3 through a control module.

[0036] The timer 101 controls the fans 3 on the left and right sides to start up in turn for one hour through the control module. When the fan 3 on the left side starts up, the electromagnet 9 on the right side is powered off, and the first spring 8 on the right side is reset, so that the conversion frame 6 on the right side drives the first magnetic block 10 on the right side to move upward and reset. The conversion frame 6 on the right side blocks the filter cover 4 on the right side upward and no longer blocks the collection bag 7 on the right side. At the same time, the electromagnet 9 on the left side is powered on. Under the action of the mutual magnetic attraction between the electromagnet 9 on the left side and the first magnetic block 10 on the left side, the first magnetic block 10 on the left side drives the conversion frame 6 on the left side to slide downward and no longer blocks the filter cover on the left side. 4, and blocks the collecting bag 7 on the left, the first spring 8 on the left is compressed, and the external air is blown into the distribution box body 1 through the filter plate 5 on the left, and the filter plate 5 on the left filters and removes dust from the incoming air, and the filtered gas is then discharged into the filter cover 4 on the right through the filter plate 5 on the right, and finally discharged through the collecting bag 7 on the right. At this time, the filtered gas will blow the dust left on the right filter plate 5 in the previous round into the filter cover 4 on the right, and finally blow it into the collecting bag 7 on the right. After one hour, take out the collecting bag 7 on the right to clean the dust, and then insert the empty collecting bag 7 back to its original position.

[0037] When the fan 3 on the right is started, the electromagnet 9 on the left is powered off, and the first spring 8 on the left is reset, so that the conversion frame 6 on the left drives the first magnetic block 10 on the left to move upward and reset, and the conversion frame 6 on the left blocks the filter cover 4 on the left upward and no longer blocks the collection bag 7 on the left. At the same time, the electromagnet 9 on the right is powered on, and under the effect of the mutual magnetic attraction between the electromagnet 9 on the right and the first magnetic block 10 on the right, the first magnetic block 10 on the right drives the conversion frame 6 on the right to slide downward and no longer blocks the filter cover 4 on the right, and blocks the collection bag 7 on the right. The first spring 8 is compressed, and the external air is blown into the distribution box body 1 through the right filter plate 5. The right filter plate 5 filters and removes dust from the incoming air. The filtered gas is then discharged into the left filter cover 4 through the left filter plate 5, and finally discharged through the left collection bag 7. At this time, the filtered gas will blow the dust left on the left filter plate 5 in the previous round into the left filter cover 4, and finally blow into the left collection bag 7. After one hour, the left collection bag 7 is taken out to clean the dust, and then the empty collection bag 7 is inserted back to its original position. This reciprocating process allows the device to not only alternately filter dust while continuously exchanging ventilation, but also clean and collect residual dust accumulated at the vents.

[0038] Embodiment 2: Based on embodiment 1, Figure 4-Figure 5As shown, it also includes a collecting rack 11 corresponding to the fan 3, the collecting rack 11 is fixedly connected to the rotating shaft of the corresponding fan 3, the side of the collecting rack 11 close to the adjacent collecting bag 7 is connected to a downward inclined pipe, the collecting rack 11 is in contact with the adjacent filter plate 5, a collecting groove 111 is opened in the middle of the collecting rack 11, and the side of the collecting rack 11 close to the collecting groove 111 is set as an inclined surface, when the collecting rack 11 rotates, the inclined surface is driven to rotate to scrape off the stubborn dust on the adjacent filter plate 5, a collecting plate 12 is fixedly connected to the filter cover 4, the collecting rack 11 is located in the adjacent collecting plate 12, and the collecting rack 11 is rotatably connected to the adjacent collecting plate 12, the interior of the collecting plate 12 is set as a cavity, and the collecting rack 11 is communicated with the cavity of the collecting plate 12 through the collecting groove 111.

[0039] When the fan 3 is started, it drives the collecting rack 11 thereon to rotate synchronously, so that the collecting rack 11 close to the inclined surface of the collecting slot 111 scrapes off the stubborn dust on the adjacent filter plate 5, and the scraped dust enters the collecting slot 111 on the same side. During the rotation of the collecting rack 11, the dust in the collecting slot 111 is thrown into the collecting tray 12 on the same side, and falls into the collecting bag 7 on the same side through the inclined pipe of the collecting tray 12, thereby strengthening the cleaning and collecting of the residual dust accumulated at the vent.

[0040] like Figure 6-Figure 7 As shown, it also includes a first baffle 13 corresponding to the collection plate 12, and the first baffle 13 is rotatably connected to the corresponding collection plate 12. A ring 15 with a notch is fixedly connected to one side of the collection frame 11 close to the adjacent collection plate 12. When the ring 15 rotates, it contacts the adjacent first baffle 13, and a torsion spring 14 is fixedly connected between the first baffle 13 and the adjacent collection plate 12.

[0041] When the fan 3 is started, it drives the collection frame 11 thereon to rotate synchronously, thereby driving the circular ring 15 thereon to rotate until it contacts the first baffle 13 on the same side. Under the squeezing effect of the circular ring 15, the first baffle 13 on the same side rotates to a vertical state, and the torsion spring 14 on the same side is deformed. The dust scraped off by the collection frame 11 rotates in the same direction as the collection frame 11. When the dust rotates to the first baffle 13 on the same side, it is blocked by the first baffle 13 and accumulates on the side of the first baffle 13 close to the pipe, so that the dust can more easily and quickly tilt and fall into the collection bag 7 on the same side.

[0042] When the fan 3 stops rotating, the ring 15 disengages from the first baffle 13, and the torsion spring 14 resets to drive the first baffle 13 to rotate to a lying state, thereby preventing some dust in the collection frame 11 from accumulating on the side of the first baffle 13 away from the pipe when the rotation stops and being unable to enter the pipe for discharge.

[0043] like Figure 8-Figure 9As shown, it also includes a second spring 16 symmetrically distributed along the upper and lower sides of the filter plate 5, the second spring 16 is fixed between the filter plate 5 and the distribution box body 1, the collection frame 11 is fixed with a lever 17, the filter plate 5 is fixed with a fixing column 18, the end of the fixing column 18 is set to a convex ball shape, and the lever 17 is squeezed and matched with the adjacent fixing column 18 when rotating.

[0044] When the fan 3 is started, the collection rack 11 thereon is driven to rotate synchronously, thereby driving the lever 17 thereon to rotate. The lever 17 squeezes the fixed column 18 on the same side, thereby driving the filter plate 5 on the same side to slide toward the second spring 16 on the same side. The second spring 16 on the same side is compressed. When the lever 17 rotates to disengage from the fixed column 18, the second spring 16 is reset to drive the filter plate 5 to slide toward the side close to the collection rack 11 on the same side. In this way, the filter plate 5 filters and removes dust from the incoming air while intermittently vibrating back and forth left and right, further strengthening the cleaning of residual dust accumulated at the vents.

[0045] Embodiment 3: Based on embodiment 2, Figure 10-11 As shown, it also includes a fixing rod 19 corresponding to the conversion frame 6, the fixing rod 19 is fixedly connected to the corresponding conversion frame 6, and the conversion frame 6 is rotatably connected to a second baffle plate 20, and the second baffle plate 20 is set to be a lightweight plate.

[0046] In order to prevent the dust in the collection bag 7 from flowing back from the bottom of the filter cover 4 to the inside of the distribution box body 1 under the action of external wind when the power is off, that is, when the air circulation of the distribution box is stopped, a second baffle 20 is provided to block it. When the power is on, the conversion frame 6 on the side where the fan 3 is started moves downward, which will drive the second baffle 20 on the same side to be inserted downward into the collection bag 7. At the same time, the gas circulation will blow open the second baffle 20 on the other side without affecting the circulation of the gas.

[0047] like Fig.10 As shown, it also includes a second magnetic block 21 corresponding to the filter cover 4. The second magnetic block 21 is fixedly connected to the lower part of the corresponding filter cover 4. The upper part of the second baffle 20 is fixedly connected to a third magnetic block 22. The third magnetic block 22 moves downward and cooperates with the adjacent second magnetic block 21 through magnetic attraction.

[0048] In order to prevent the conversion frame 6 from driving the second baffle 20 on the same side to be inserted downward into the collection bag 7 and being pushed back to its original position by the dust collected in the collection bag 7, the air on the starting side of the fan 3 is blocked by the returned second baffle 20, and the air cannot enter, thereby preventing ventilation. Specifically, when the second baffle 20 moves downward, it will drive the third magnetic block 22 to move downward until it contacts the second magnetic block 21. Under the action of the magnetic attraction force, the second baffle 20 can be prevented from being pushed back to its original position.

[0049] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the appended claims of the application.
