DETAILED DESCRIPTION

[0013] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0014] See also Figure 1-5 As shown in the figure, a dust-proof and heat-dissipating power cabinet provided in this embodiment includes a power cabinet housing 1, an air inlet 27 is provided inside the power cabinet housing 1, a dust filter 4 is replaceably installed on one side of the air inlet 27, and an engine compartment 28 is connected to the other side of the engine compartment 28, and a fan 2 is fixedly installed in the engine compartment 28.

[0015] Specifically, a fan 2 is fixedly installed at the machine compartment 28 inside the power cabinet housing 1. The fan 2 is used to generate wind attraction to suck the gas outside the power cabinet housing 1 into the interior of the power cabinet housing 1 through the dust filter 4 and the air inlet duct 27; wherein the fan 2 can be precisely controlled through an encoder, and information such as the current rotation speed of the fan 2 can be obtained; a wind speed sensor can be set on the inner wall of the air inlet duct 27 of the power cabinet housing 1 to obtain the actual wind speed information in the air inlet duct 27.

[0016] It can be understood that when the fan 2 starts working, the air mixed with dust outside the power cabinet housing 1 will be attracted, and the external air will first pass through the dust filter 4, so that most of the dust in the external air will be blocked and collected by the dust filter 4, and then the filtered air will be sucked into the cabinet through the air inlet duct 27, while ensuring the heat dissipation of the cabinet, reducing the impact of dust on the electronic components inside the cabinet; at this time, the wind speed information obtained by the wind speed sensor is within a reasonable range.

[0017] For further information, please refer to Figure 1 A guide groove 3 is provided on the inner wall of the power cabinet housing 1 on one side of the dust filter 4, and the dust filter 4 is slidably connected in the guide groove 3. An upper net warehouse 29 is provided inside the power cabinet housing 1 above the air inlet 27, and a plurality of spare mesh sheets 31 are installed in the upper net warehouse 29. The lower net warehouse 30 is provided below the air inlet 27.

[0018] Specifically, both sides of the dust filter 4 and the spare mesh 31 are provided with protrusions, which match the guide groove 3. The dust filter 4 is slidably connected in the guide groove 3 through the protrusions. The guide groove 3 extends downward to the inside of the lower mesh bin 30. The dust filter 4 can slide along the guide groove 3 from the connection opening between the air inlet 27 and the lower mesh bin 30 to the lower mesh bin 30;

[0019] A slope inclined toward the dust filter 4 is provided in the online bin 29, and multiple spare meshes 31 are movably stored on the slope, wherein the sidemost spare mesh is located above the dust filter 4. When the dust filter 4 slides along the guide groove 3, the spare mesh 31 will fall from the opening where the online bin 29 is connected to the air inlet 27 into the air inlet 27.

[0020] It is understandable that when the amount of dust blocked and collected on the dust filter 4 reaches a certain amount, the dust will gradually hinder the entry of external air, thereby causing the airflow in the air inlet duct 27 to gradually become smaller. When the wind speed information monitored by the wind speed sensor is too small, the encoder controls the fan 2 to increase the rotation speed. Preferably, the fan 2 can be quickly increased to the maximum wind speed, and the attraction generated by the fan 2 will be greatly increased. At this time, the increased wind force will not only inhale more external air, but also attract the dust filter 4 to move along the guide groove 3 toward the fan 2, until the dust filter 4 moves to the opening where the air inlet duct 27 is connected to the lower mesh bin 30, and the dust filter 4 continues to slide along the guide groove 3 into the lower mesh bin 30; at the same time, the spare mesh 31 in the upper mesh bin 29 falls from the opening where the upper mesh bin 29 is connected to the air inlet duct 27;

[0021] The above arrangement can not only increase the rotation speed to increase the air intake when the dust filter 4 is clogged with dust, but also drive the automatic replacement of the dust filter 4 and the spare mesh 31 when the dust filter 4 is seriously clogged, thereby avoiding the situation in which the traditional scraper is adsorbed on the dust filter 4 by the wind force of the fan 2 after scraping off the dust, or even sucked into the cabinet, thereby greatly improving the heat dissipation and dust prevention effect of the power cabinet and reducing the manual maintenance cost.

[0022] When the dust filter 4 is replaced, the resistance of air passing through the dust filter 4 is greatly reduced. At this time, the speed of the fan 2 is still relatively large, and the wind speed data monitored by the wind speed sensor is too large. The encoder controls the fan 2 to slow down the speed to keep the air flow rate in the air inlet duct within a reasonable range.

[0023] Furthermore, a stopper 5 is provided on one side of the dust filter 4 , and the stopper 5 is elastically connected to the inner wall of the power cabinet housing 1 .

[0024] Specifically, a baffle 5 is elastically connected to the inside of the power cabinet housing 1 on the side of the dust filter 4 close to the fan 2. The baffle 5 may include a baffle and a spring. The baffle is elastically connected to the inner wall of the power cabinet housing 1 through the spring. The baffle 5 can provide a certain buffering force in the horizontal direction to reserve buffering time for the encoder to adjust the speed of the fan 2, thereby preventing the spare mesh 31 that has just fallen from the upper net bin 29 to replace the dust filter 4 from being immediately attracted by the wind of the fan 2 and falling into the lower net bin 30.

[0025] Furthermore, a synchronous belt 20 is sleeved on the output end of the fan 2, a rotating member 19 is provided at the other end of the synchronous belt 20, a second conical tooth 18 is provided at the other end of the rotating member 19, the second conical tooth 18 is meshed with the first conical tooth 17, a reciprocating screw rod 16 is provided on the first conical tooth 17, a conveying plate 15 is sleeved on the reciprocating screw rod 16, a rotating rod 21 is provided below the conveying plate 15, an impact member 22 is provided on the rotating rod 21, a gear 23 is provided at one end of the rotating rod 21, and the gear 23 is meshed with a rack 24 mounted on the inner wall of the power cabinet housing 1.

[0026] Specifically, one end of the synchronous belt 20 is sleeved on the outer wall of the output end of the fan 2, and the other end is sleeved on the outer wall of the rotating member 19. When the fan 2 rotates, the rotating member 19 can rotate synchronously under the transmission of the synchronous belt 20, and the other end of the rotating member 19 is fixedly connected to the second conical tooth 18; the inside of the power cabinet housing 1 is movably connected with a conveying plate 15, and the conveying plate 15 is sleeved on the outer wall of the reciprocating screw 16. The conveying plate 15 can move up and down in the power cabinet housing 1 along the direction of the reciprocating screw 16. The reciprocating screw 16 is arranged vertically, and the reciprocating screw 16 extends upward to the upper net warehouse 29, and the reciprocating screw 16 extends downward to the lower net warehouse 30. The lower end of the reciprocating screw 16 is fixedly connected with the first conical tooth 17, and the first conical tooth 17 and the second conical tooth 18 are meshed. When the rotating member 19 rotates, it can drive the reciprocating screw 16 to rotate, thereby driving the conveying plate 15 to move up and down along the direction of the reciprocating screw 16.

[0027] Furthermore, the guide groove 3 can extend upward from the lower net bin 30 to the upper net bin 29, and then extend from the upper net bin 29 to the air inlet duct 27, forming a closed loop, guiding the dust filter 4 to move along the path of the guide groove 3; preferably, the conveying plate 15 can be connected to the reciprocating screw 16 through a telescopic part; a rotating rod 21 is rotatably connected to the outer wall below the conveying plate 15, and an impact member 22 is fixedly connected to the outer wall of the rotating rod 21, and a gear 23 is fixedly connected to one end of the rotating rod 21, and a rack 24 is meshed with the outer wall of the gear 23, and the rack 24 is fixedly connected to the inner wall of the power cabinet housing 1, and the rack 24 is arranged parallel to the reciprocating screw 16.

[0028] It can be understood that the operation of the fan 2 will drive the synchronous belt 20 to rotate, and the rotation of the synchronous belt 20 will drive the second conical gear 18 to rotate through the rotating member 19. The rotation of the second conical gear 18 will drive the reciprocating screw 16 to rotate through the first conical gear 17. The rotation of the reciprocating screw 16 will drive the conveying plate 15 to reciprocate up and down. When the conveying plate 15 reciprocates up and down, the conveying plate 15 will drive the gear 23 to rotate along the rack 24 through the rotating rod 21, so that the gear 23 is driven by the rack 24 to rotate. The rotation of the gear 23 will drive the rotating rod 21 to rotate, and the rotating rod 21 drives the impact member 22 to rotate. When the spare mesh 31 accumulates a certain amount of dust and falls into the lower mesh bin 30, the dust filter 4 will be gradually pushed toward the conveying plate 15. When the impact member 22 contacts the dust filter 4, the impact member 22 will reciprocate up and down. The surface of the dust filter 4 is hit, so that the dust accumulated on the dust filter 4 is continuously impacted and gradually falls off, so as to achieve the effect of cleaning the dust accumulated on the dust filter 4; at the same time, as the spare mesh 31 continues to fall into the lower mesh bin 30, the dust filter 4 at the front end will be pushed to the top of the conveying plate 15, and the conveying plate 15 will send the dust filter 4 that has been cleaned of dust into the upper bin 29 along the direction of the guide groove 3 and the reciprocating screw 16, waiting for replacement; the above process can automatically knock off the dust accumulated on the dust filter 4 by driving the conveying plate 15 and the impact member 22 through the fan 2, and can also automatically send the clean dust filter 4 into the upper bin 29 for filling, thereby realizing the automatic replacement, automatic cleaning and automatic filling of the dust filter 4, without manual intervention, and also helping to reduce the downtime of equipment for maintenance and extend the life of the equipment.

[0029] Furthermore, a pressure piece 25 is elastically connected to the upper web bin 29 via a third spring 26 , and the other end of the reciprocating screw rod 16 extends to below the pressure piece 25 in the upper web bin 29 .

[0030] Specifically, a pressure piece 25 is elastically connected to the interior of the online bin 29 of the power cabinet housing 1. When the dust filter 4 is lifted to the online bin 29, the dust filter 4 will press open the pressure piece 25, causing the pressure piece 25 to squeeze the third spring 26 to contract until the dust filter 4 completely enters the online bin 29. The third spring 26 stretches and pushes the pressure piece 25 to reset, allowing the pressure piece 25 to push the dust filter 4 to move to the tail of the spare mesh 31 to wait for standby.

[0031] Further, it should be noted that in the process of removing dust from the dust filter 4, the above scheme needs to rely on the subsequent spare mesh 31 to continuously push the dust filter 4 to move, resulting in the need to store a considerable number of spare meshes 31 to trigger the cycle. In addition, the meshes are close to each other, which will also cause the impact member 22 to knock and remove dust. The effect is reduced, so further design can be made, as shown below:

[0032] Please read further Figure 3, also includes: a guide rod 7 and a limit member 13, the guide rod 7 is installed in the lower net bin 30, the guide rod 7 is sleeved with a first spring 8, the upper end of the guide rod 7 is provided with a stop rod 6, the inner wall of the lower net bin 30 is also provided with a slide groove, the stop rod 6 is slidably connected in the slide groove, a pressure plate 9 is provided below the first spring 8, an air bag 10 is provided below the pressure plate 9, a telescopic rod 11 is provided on one side of the air bag 10, and a push rod 12 is provided at one end of the telescopic rod 11; the limit member 13 is elastically connected to the inner wall of the power cabinet housing 1 through a second spring 14, and the position of the limit member 13 matches the impact member 22.

[0033] Specifically, the interior of the lower mesh bin 30 is located on a side away from the fan 2 and is fixedly connected to a guide rod 7, on which a first spring 8 is sleeved, and an upper end of the guide rod 7 is sleeved with a blocking rod 6, and the lower end surface of the blocking rod 6 is connected to the first spring 8. The blocking rod 6 is located at the opening where the air inlet 27 and the lower mesh bin 30 are connected. When the dust filter 4 moves to this point, the blocking rod 6 will slide down together with the dust filter 4 under the action of the gravity of the dust filter 4.

[0034] Furthermore, the slide groove slidably connected to the blocking rod 6 is inclined in the direction of the guide rod 7, so that when the blocking rod 6 and the dust filter 4 slide down together, the blocking rod 6 will gradually separate from the dust filter 4 in the direction of the guide rod 7. When completely separated, the dust filter 4 continues to slide down along the guide groove 3, and the blocking rod 6 will return upward along the slide groove under the action of the first spring 8. A cavity is reserved at the connection between the blocking rod 6 and the guide rod 7 to facilitate the movement of the blocking rod 6 toward the guide rod 7.

[0035] The outer wall of the first spring 8 is fixedly connected with a pressure plate 9, the bottom of the pressure plate 9 is fixedly connected with an airbag 10, the side of the airbag 10 close to the fan 2 is fixedly connected with a telescopic rod 11, and the end of the telescopic rod 11 close to the fan 2 is fixedly connected with a push rod 12; the limit member 13 is elastically connected to the inner wall of the power cabinet housing 1 through the second spring 14, and when the limit member 13 limits the dust filter 4, the position of the dust filter 4 can be hit by the impact member 22.

[0036] The above process pushes the dust filter net 4 to be stuck at the limit piece 13 by the gravity of the spare mesh 31, thereby reducing the number of spare meshes 31 and preventing the dust from being caught by the impact piece 22.

[0037] In addition, after the baffle rod 6 drops to a certain distance, the spare mesh 31 will separate from the baffle rod 6, thereby causing the first spring 8 to extend and push the baffle rod 6 to reset. At the same time, when the first spring 8 extends and resets, the first spring 8 will pull the airbag 10 to reset through the pressure plate 9, so that the gas inside the telescopic rod 11 is sucked into the interior of the airbag 10, allowing the telescopic rod 11 to drive the push rod 12 to reset.

[0038] It should be noted that after the new spare mesh 31 accumulates enough dust to press open the blocking piece 5 and descend along the guide groove 3, the push rod 12 will push the previous spare mesh 31 to move, press open the limit piece 13 and push the cleaned dust filter 4 along the guide groove 3 to the top of the conveying plate 15, so that when the conveying plate 15 rises, it drives the cleaned dust filter 4 to slide along the guide groove 3 and rise into the net bin 29, waiting to be recycled, so as to achieve the effect of automatically cleaning the dust filter 4 that accumulates too much dust and recycling it.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
