[0015] The beneficial effects of the present invention are as follows:

[0016] (1) The present invention effectively prevents dust and flocs from entering the interior of the shell through the dust filter, thereby affecting the service life of the new energy charging pile transformer inside the shell. The dust collecting shell and the internal roller brush that move back and forth, combined with the back-blowing assistance of the blower pipe in the air outlet hood, can comprehensively clean and collect the dust and flocs on the dust filter, avoid reducing the heat dissipation effect inside the shell, eliminate the secondary adsorption of dust impurities, and further avoid the problem of dust impurities continuously accumulating on the surface of the dust filter.

[0017] (2) The present invention also uses the reverse rotation of the roller brush and the one-way bearing to drive the linkage frame, the tooth comb plate and the arc plate to move. On the one hand, the tooth comb plate is prompted to scrape the dust and impurities on the arc filter screen and collect them into the dust filter bag, ensuring the smooth discharge of hot air in the dust collection shell and maintaining the high efficiency of back-blowing auxiliary cleaning. On the other hand, the tooth comb plate is separated from the roller brush, and the linkage frame and the tooth comb plate slide relative to each other, so that the linkage frame automatically cleans the flocs on the tooth comb plate.

[0018] (3) The present invention also uses a synchronous belt to cause the air outlet hood to reciprocate, causing the sliding frame to carry multiple elastic knocking blocks to synchronously reciprocate and hit the dust filter, thereby assisting in cleaning impurities in the mesh of the dust filter, further improving the anti-blocking and cleaning effect of the dust filter; and combined with the independent setting of multiple dust filters, and the cooperation of the dust shield and the dust shield guide plate, it can temporarily collect the dust cleaned in the mesh and falling to the side of the air outlet hood, and then with the help of the descent of the air outlet hood, the baffle at the dust outlet below the dust filter moves upward, combined with back-blowing auxiliary cleaning, the dust cleaned by vibration is effectively collected and processed to avoid the problem that this part of dust is difficult to discharge.

[0039] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 3 、 Figure 8 、 Figure 9 and Figure 11-Figure 15 As shown, the problem in the prior art that the dust and flocculent matter contained in the flowing air is difficult to dissipate heat efficiently while providing effective dust protection for the charging pile transformer due to the lack of a structure to effectively filter and intercept it can be solved by the following solution;

[0041] The new energy charging pile transformer with a heat dissipation assembly in this embodiment includes a housing 1 for mounting the new energy charging pile transformer. A fixing frame 11 is fixedly mounted on the opening side of the housing 1, and a dust filter 12 is mounted on the fixing frame 11. A dust collection cleaning component 2 and a backflush component 3 are provided in the housing 1.

[0042] The dust collecting cleaning assembly 2 includes a dust collecting shell 21 located on one side of the fixed frame 11, a roller brush 22 is rotatably installed inside the dust collecting shell 21, and a driving motor for driving the roller brush 22 to rotate is installed. The driving motor drives the roller brush 22 to rotate, and the rotating roller brush 22 cleans the dust and flocs on the dust filter 12. An arc filter 23 and an air outlet pipe 1 24 are fixedly installed on the dust collecting shell 21. The air outlet pipe 1 24 is used to discharge the air entering the dust collecting shell 21. The setting of the arc filter 23 prevents the air from being discharged synchronously with the dust and flocs when being discharged, thereby avoiding repeated adsorption and accumulation of dust and impurities, and thus making it difficult to maintain efficient cleaning and heat dissipation.

[0043] The backflush assembly 3 includes an air outlet hood 31 located on the other side of the fixed frame 11, and an air blowing pipe 32 with multiple air outlet holes is installed inside the air outlet hood 31. An induced draft fan 13 is installed on one side of the housing 1, and an induced draft pipe 14 is installed on the induced draft fan 13, which communicates with the interior of the housing 1 and blows air into the air blowing pipe 32. One end of the induced draft pipe 14 is located on the side of the housing 1 away from the fixed frame 11, so that when the air inside the housing 1 is extracted, the flow effect of the air inside the housing 1 is improved;

[0044] When cooling the transformer installed inside the housing 1, the induced draft fan 13 extracts the hot air inside the housing 1 through the induced draft duct 14, and the external air enters the housing 1 through the dust filter 12, taking away the heat generated by the transformer inside the housing 1, and the dust and flocs in the air are filtered and intercepted by the dust filter 12.

[0045] On the inner wall of the housing 1, fixed base 15 is installed on both sides of the dust collecting shell 21, and fixed base 2 16 is installed on both sides of the air outlet cover 31. The interiors of fixed base 15 and fixed base 2 16 are both rotatably connected to synchronous wheels, and the synchronous wheels are connected through a synchronous belt 17;

[0046] The synchronous belt 17 is driven to rotate by the synchronous wheel, and then the dust collecting shell 21 and the air outlet cover 31 are driven to perform reciprocating lifting and lowering movements, so as to achieve a comprehensive cleaning effect on the dust filter 12. Sealing belts are installed on both side ends of the synchronous belt 17, and a sealing groove is provided on the inner side wall of the fixed seat to slide with the sealing belt to achieve sealing inside the corresponding fixed seat.

[0047] A rotating rod fixed to the corresponding synchronous wheel is rotatably connected between the two sets of fixed seats 15 and the two sets of fixed seats 2 16. A servo motor driving the corresponding rotating rod is installed on the housing 1 to rotate, so as to achieve the synchronous rotation effect of the synchronous belt 17 in the fixed seat 15 and the fixed seat 2 16, thereby achieving the synchronous lifting effect of the dust collecting shell 21 and the air outlet cover 31;

[0048] By shielding a certain area of ​​the dust filter 12 during cleaning with the help of the air outlet cover 31 and the dust collecting shell 21, it is prevented that outside air enters the interior of the housing 1, which would make it difficult to effectively collect the cleaned dust and impurities.

[0049] The end of the air outlet pipe 1 24 is fixedly connected to the synchronous belt 17 on the corresponding fixing seat 15. The end of the air outlet pipe 1 24 passes through the corresponding synchronous belt 17, so that the air outlet pipe 1 24 is communicated with the interior of the fixing seat 15. The fixing seat 15 is equipped with an air outlet pipe 2 for discharging the air entering the fixing seat 15. The discharge area is different from the flow path of the outside air entering the shell 1, so as to avoid the exhaust hot air being introduced into the shell 1 too quickly, thereby reducing the heat dissipation effect. The synchronous belt 17 rotating in the fixing seat 15 drives the dust collecting shell 21 to move up and down through the air outlet pipe 1 24;

[0050] The two ends of the blowing pipe 32 are fixedly connected to the synchronous belt 17 on the corresponding fixing seat 16, and the free end of the induced draft pipe 14 is fixedly connected to the corresponding fixing seat 16. One end of the blowing pipe 32 passes through the synchronous belt 17 in one of the fixing seats 16, and the fixing seat 16 is connected to the induced draft pipe 14. The synchronous belt 17 carries the dust collecting housing 21 and the air outlet cover 31 up and down, realizing the sealed flow of gas. The hot air extracted by the induced draft fan 13 is injected into the interior of the fixing seat 16 on one side through the induced draft pipe 14;

[0051] The hot air is then injected into the blowing pipe 32 connected to it, and blown onto the corresponding dust filter 12 from multiple air outlets, and the dust cleaned by the roller brush 22 is assisted to be blown into the dust collecting shell 21, and intercepted by the arc filter 23. The hot air enters the interior of the fixed seat 15 through the air outlet pipe 1 24, and is then discharged through the air outlet pipe 2. The dust collecting shell 21 and the air outlet cover 31 are both equipped with guide frames that slide with the corresponding fixed seats to achieve the stability of the lifting and lowering of the two.

[0052] A dust filter bag 25 is detachably installed at the dust outlet of the dust collecting shell 21. The dust filter bag 25 is installed to the dust collecting shell 21 by screws, and the interior of the dust collecting shell 21 is slidably connected with an arc-shaped plate 26 for blocking the dust outlet. A spring 1 is installed between one side of the arc-shaped plate 26 and the dust collecting shell 21. The dust outlet is opened by moving the arc-shaped plate 26 and compressing the spring 1, so that the dust and impurities in the dust collecting shell 21 enter the dust filter bag 25 for separation and collection. The dust filter bag 25 is then disassembled and taken out for centralized cleaning of the dust and impurities.

[0053] A tooth comb plate 28 is connected to the arc plate 26 via an elastic rod 27. A linkage frame 29 that slides with the tooth comb plate 28 is rotatably mounted on the roller shaft of the roller brush 22 via a one-way bearing. A guide limit block 210 is fixedly connected to the top of the dust collecting shell 21. When the tooth comb plate 28 contacts the guide limit block 210, the tooth comb plate 28 contacts the rotating roller brush 22, thereby cleaning the flocs on the roller brush 22 and enabling the roller brush 22 to efficiently clean the dust filter 12.

[0054] When there is a lot of dust in the dust collecting housing 21, the roller brush 22 rotates in the opposite direction, and the one-way bearing drives the linkage frame 29 and the tooth comb plate 28 to rotate. During the rotation of the two, the tooth comb plate 28 separates from the guide limit block 210. With the elastic force of the elastic rod 27, the tooth comb plate 28 is separated from the roller brush 22 and contacts the curved filter 23. At the same time, the contact elastic rod 27 pushes the curved plate 26 to move to open the dust outlet and compress the spring 1.

[0055] The tooth comb plate 28 slides on the curved filter screen 23, pushing the dust on the curved filter screen 23 into the dust filter bag 25 for collection. When the tooth comb plate 28 is separated from the guide limit block 210, the linkage frame 29 slides relative to the tooth comb plate 28, and the linkage frame 29 synchronously and automatically cleans the flocs on the tooth comb plate 28.

[0056] Example 2: Please refer to Figures 4-10 As shown, the following solutions can be used to solve the problem that it is difficult to further efficiently clean the impurities in the mesh and that the impurities that have passed through the screening cannot be intercepted and discharged during the cleaning process, thereby reducing the dust prevention effect;

[0057] In this embodiment, a sliding frame 33 is slidably connected to the air outlet cover 31, and a plurality of elastic knocking blocks 34 are fixedly mounted on the sliding frame 33. The sliding frame 33 carries the plurality of elastic knocking blocks 34 and synchronously reciprocates to strike the dust filter 12, thereby assisting in cleaning impurities in the mesh of the dust filter 12. A guide wheel 35 that cooperates with the corresponding synchronous belt 17 is mounted on one side of the sliding frame 33. A through slot for the sliding frame 33 to pass through is formed on the second fixed seat 16 on one side, so that the guide wheel 35 on the sliding frame 33 can contact the tooth groove side of the corresponding synchronous belt 17.

[0058] A second spring is installed between the sliding frame 33 and the air outlet cover 31. The downward movement of the sliding frame 33 carried by the air outlet cover 31 causes the guide wheel 35 on the sliding frame 33 to contact the tooth groove side of the corresponding synchronous belt 17, and the second spring causes the guide wheel 35 to fit tightly with the side of the synchronous belt 17 and the sliding fixed seat 16, so that the sliding frame 33 carries multiple elastic knocking blocks 34 to synchronously reciprocate and impact the dust filter 12. The upward movement of the contact side of the synchronous belt 17 and the guide wheel 35 can further accelerate the reciprocating motion frequency of the elastic knocking block 34, thereby further improving the effect of vibration cleaning.

[0059] Multiple dust filters 12 are arranged at equal intervals. By independently arranging the dust filters 12, it is prevented from being knocked and vibrated, which makes it difficult to effectively intercept and process dust falling from the dust filter 12 on the side of the air outlet hood 31. A dust outlet is formed between the bottom of the dust filter 12 and the fixing frame 11 for discharging impurities cleaned by vibration.

[0060] A dust shield plate 18 is installed on the fixed frame 11 and below the corresponding dust filter 12, and the dust shield plate 18 is rotatably connected to the fixed frame 11 through rotating rods fixed on both sides. The bottom of the air outlet hood 31 is fixedly connected with a dust shield guide plate 36 that cooperates with the dust shield plate 18. The dust cleaned out and falling to the side of the air outlet hood 31 is temporarily collected by combining the dust shield plate 18 below the corresponding dust filter 12 with the dust shield guide plate 36.

[0061] A baffle 19 is slidably mounted on the fixed frame 11 and below the corresponding dust filter 12, and tooth plates 110 are symmetrically fixed on both sides of the bottom of the baffle 19. An incomplete gear 111 that meshes with the tooth plate 110 is rotatably mounted on the rotating rod, and an L-shaped limit block 112 that cooperates with the teeth of the incomplete gear 111 is fixedly connected to the rotating rod;

[0062] The downward movement of the dust shield guide plate 36 carried by the air outlet cover 31 causes the dust shield plate 18 to deflect downward, and the L-shaped limit block 112 on the rotating rod comes into contact with the teeth on the incomplete gear 111, causing the incomplete gear 111 to rotate synchronously, and driving the toothed plate 110 meshing with it to move, pushing the corresponding toothed plate 110 to carry the baffle 19 upward, causing the dust outlet below the dust filter 12 to open;

[0063] The hot air blown out from the blowing pipe 32 blows the dust that falls from the dust filter 12 to the side of the air outlet hood 31 into the dust collecting shell 21. Finally, the air outlet hood 31 is separated from the dust shield 18, and the gravity of the baffle 19 causes the baffle 19 and the dust shield 18 to reset and block the dust outlet below the dust filter 12 again. When the air outlet hood 31 moves upward, the dust shield 18 is driven to deflect upward, and the L-shaped limit block 112 does not contact the teeth on the incomplete gear 111, and thus will not cause interference with the downward movement of the baffle 19.

[0064] Example 3: Please refer to Figures 1-15 As shown, the present invention also proposes a method for using a new energy charging pile transformer with a heat dissipation assembly, comprising the following steps:

[0065] Step 1: Install the new energy charging pile transformer inside the housing 1. When the transformer is dissipating heat, the induced draft fan 13 extracts the hot air inside the housing 1 through the induced draft duct 14. The external air enters the housing 1 through the dust filter 12, taking away the heat generated by the transformer inside the housing 1. The dust and flocs in the air are filtered and intercepted by the dust filter 12.

[0066] Step 2: The driving motor drives the roller brush 22 to rotate. The rotating roller brush 22 cleans the dust and flocs on the dust filter 12. At the same time, the hot air extracted by the induced draft fan 13 is injected into the interior of the second fixed seat 16 on one side through the induced draft pipe 14, and then injected into the blowing pipe 32 connected thereto, and blown onto the corresponding dust filter 12 from multiple air outlets. The dust cleaned by the roller brush 22 is auxiliary blown into the dust collecting shell 21 and intercepted by the curved filter 23. The hot air enters the interior of the fixed seat 15 through the outlet pipe 1 24 and is finally discharged through the outlet pipe 2. The flocs on the roller brush 22 are cleaned by the tooth comb plate 28.

[0067] Step 3: The servo motor drives the corresponding rotating rod to rotate, and the rotating rod cooperates to drive the synchronous wheel to rotate, and the synchronous wheel causes the synchronous belt 17 to rotate, and then combines with the blowing pipe 32 and the air outlet pipe 1 24 to cause the air outlet cover 31 and the dust collecting shell 21 to move up and down synchronously, completing the comprehensive cleaning of the dust filter 12. At the same time, the air outlet cover 31 and the dust collecting shell 21 are used to prevent outside air from entering the interior of the shell 1, resulting in poor back-blowing cleaning effect. The air outlet cover 31 carries the sliding frame 33 to move downward, causing the guide wheel 35 on the sliding frame 33 to contact the tooth groove side of the corresponding synchronous belt 17, and the cooperation of the spring 2 causes the sliding frame 33 to carry multiple elastic knocking blocks 34 to synchronously reciprocate and impact the dust filter 12, thereby assisting in cleaning impurities in the mesh of the dust filter 12.

[0068] The dust collecting shell 21 is blown away by the hot air from the blowing pipe 32, and the dust on the dust filter 12 that falls to the side of the air outlet hood 31 is blown away by the hot air from the blowing pipe 32. Finally, the air outlet hood 31 is separated from the dust shield 18, and the gravity of the baffle 19 causes the baffle 19 and the dust shield 18 to return to their original position, thus blocking the dust outlet under the dust filter 12 again.

[0069] Step 5: When there is a lot of dust in the dust collecting shell 21, the driving motor drives the roller brush 22 to rotate in the opposite direction, and the one-way bearing drives the linkage frame 29 and the tooth comb plate 28 to rotate. During the rotation of the two, on the one hand, the tooth comb plate 28 is separated from the guide limit block 210, and the elastic force of the elastic rod 27 is used to separate the tooth comb plate 28 from the roller brush 22, and the linkage frame 29 slides relative to the tooth comb plate 28. The linkage frame 29 automatically cleans the flocs on the tooth comb plate 28, and on the other hand, the arc plate 26 is moved to open the dust outlet and compress the spring 1, and the tooth comb plate 28 is used to slide on the arc filter 23 to push the dust on the arc filter 23 and the flocs cleaned from the tooth comb plate 28 into the dust filter bag 25 for collection. The dust filter bag 25 is then disassembled and taken out for centralized cleaning.

[0070] After the dust in the dust collecting shell 21 is cleaned, the driving motor drives the roller brush 22 to rotate forward again. With the help of the compression force of spring 1, the arc plate 26 closes the dust outlet and the tooth comb plate 28 moves to the guide limit block 210. With the guidance of the guide limit block 210, the tooth comb plate 28 is prompted to contact with the roller brush 22, and the flocs on the roller brush 22 are cleaned again, so that the roller brush 22 can efficiently clean the dust filter 12.

[0071] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
