Detailed implementation manners

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] Please refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 6 as shown, the present invention provides a technical solution, and the specific improvements are as follows:

[0030] A dust-proof and explosion-proof DC charging pile, including a charging pile body 1. A cooling device is arranged inside the charging pile body 1 to prevent circuit aging caused by overheating and resulting in spontaneous explosion. The cooling device is a prior art and will not be described in detail in this application document. A heat dissipation port is opened on one side of the charging pile body 1. A ventilation frame 2 is fixedly arranged inside the heat dissipation port, and a filter plate 3 is movably arranged inside the ventilation frame 2. Shielding members 4 are arranged on both sides of the ventilation frame 2. The shielding member 4 includes an intermediate plate 41 fixedly arranged on both sides of the ventilation frame 2, and movable plates 43 are arranged on the front and back of the intermediate plate 41 through first telescopic curtains 42. A driving part for controlling the movement of the movable plate 43 is arranged on the top surface of the ventilation frame 2. The driving part includes a hydraulic cylinder 44 fixedly arranged on one side of the charging pile body 1 through a connecting plate, and an installation plate 45 is fixedly arranged at the extending end of the hydraulic cylinder 44. A U-shaped plate 47 is fixedly arranged between two adjacent movable plates 43 on the left and right. The U-shaped plate 47 is slidably arranged on the top surface of the ventilation frame 2. A shielding curtain is arranged at the heat dissipation port and can be telescoped, and the shielding curtain is connected to the surface of the U-shaped plate 47. The front and back of the installation plate 45 are respectively rotatably connected to the top surfaces of the two U-shaped plates 47 through inclined rods 46;

[0031] An installation frame 5 is fixedly arranged between the front and back of the inner wall of the ventilation frame 2. A groove adapted to the installation frame 5 is opened inside the filter plate 3. A cleaning member 6 is arranged inside the installation frame 5. The cleaning member 6 includes an electric slide rail 61 fixedly arranged on the bottom surface of the inner wall of the installation frame 5, and a double-rod hydraulic cylinder 62 is fixedly arranged on the top surface of the electric slide rail 61 through a sliding block. Second telescopic curtains 18 are arranged on both sides of the installation frame 5, and the second telescopic curtains 18 are connected to the surface of the sliding block. Cleaning brushes 63 are arranged inside the opposite sides of the two movable plates 43. Both extending ends of the double-rod hydraulic cylinder 62 are fixedly connected to the surface of the cleaning brush 63;

[0032] A through groove is opened on the bottom surface of the ventilation frame 2. A collection frame 7 is fixedly arranged on the bottom surface of the ventilation frame 2, and a collection box 8 is movably arranged inside the collection frame 7. A sealing plate 15 is movably arranged inside the collection frame 7. A first motor 16 is fixedly arranged on the front and back of one side of the collection frame 7 through a support frame, and one end of the output shaft of the first motor 16 is fixedly connected to a transmission gear 17 through a coupling. Teeth meshing with the transmission gear 17 are arranged on the bottom surface of the sealing plate 15;

[0033] When the charging pile body 1 is in normal use, both sides of the ventilation frame 2 are in an open state at this time. When the outside air enters the charging pile body 1 through the heat dissipation port, the dust in the air can be filtered by the filter plate 3. When it is necessary to clean the dust on the surface of the filter plate 3, control the extending end of the hydraulic cylinder 44 to drive the mounting plate 45 to descend. During the descending process of the mounting plate 45, the U-shaped plate 47 can be pushed to slide along the top surface of the ventilation frame 2 through the setting of the inclined rod 46. At this time, the two U-shaped plates 47 will drive the two movable plates 43 to move away from each other, and the first telescopic curtain 42 will be stretched until the movable plates 43 close both sides of the ventilation frame 2 through the first telescopic curtain 42;

[0034] At this time, start the double-rod hydraulic cylinder 62, so that the two extending ends of the double-rod hydraulic cylinder 62 drive the cleaning brush 63 to approach the filter plate 3 until the bristles on the cleaning brush 63 contact the surface of the filter plate 3. Then start the electric slide rail 61, and the double-rod hydraulic cylinder 62 can be controlled to slide back and forth through the electric slide rail 61. At the same time, the cleaning brush 63 moves synchronously, so as to realize the cleaning work of the dust on the filter plate 3, and the phenomenon of dust overflow and environmental pollution can be avoided during the cleaning. During the cleaning process, start the first motor 16, so that the first motor 16 drives the transmission gear 17 to rotate, and the transmission gear 17 drives the sealing plate 15 to slide to the right through the teeth, so that the through groove is opened. At this time, the dust falling during the cleaning will fall into the inside of the collection box 8 for collection. After the cleaning is completed, take out the collection box 8 and pour it out, and control the sealing plate 15 to slide to the left and control both sides of the ventilation frame 2 to open, then the subsequent normal use can be carried out. Slide the filter plate 3 out from the inside of the ventilation frame 2 to the front to replace it.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, please refer to Figure 2 and Figure 4 as shown, the specific improvements are as follows:

[0037] On both sides of the back of the charging pile body 1, protective cylinders 91 are provided, and a sealing mechanism 9 is arranged on the surface of the protective cylinder 91. The sealing mechanism 9 includes a rotating ring 92 rotatably arranged on the surface of the protective cylinder 91. A plug board 93 is movably arranged on the surface of the protective cylinder 91. An inclined slot 94 adapted to the plug board 93 is formed inside the protective cylinder 91. One side of the plug board 93 located inside the inclined slot 94 is beveled. An arc-shaped triangular plate 95 is fixedly arranged on one side of the plug board 93 located inside the protective cylinder 91. A connecting cylinder 96 is fixedly arranged at one end of the protective cylinder 91. A through hole adapted to the plug board 93 is formed inside the protective cylinder 91, and limiting blocks 97 are arranged on both sides of the inner wall of the through hole. Sliding grooves adapted to the limiting blocks 97 are formed on both sides of the plug board 93, and a buffer spring 98 is fixedly connected between the surface of one side of the inner wall of the sliding groove and the limiting block 97. On both sides of the back of the charging pile body 1, charging guns 10 are connected through connecting wires, and a sealing cover 11 adapted to the connecting cylinder 96 is arranged on the surface of the charging gun 10. On both sides of the back of the charging pile body 1, second motors 12 are fixedly arranged, and one end of the output shaft of the second motor 12 is fixedly connected with a first gear 13 through a coupling. A second gear 14 meshing with the first gear 13 is fixedly arranged on one side of the rotating ring 92 through a connecting ring;

[0038] The charging gun 10 needs to be taken out from the inside of the protective cylinder 91 before subsequent charging operations. At this time, the sealing cover 11 is far away from the connecting cylinder 96. The second motor 12 is started, so that the second motor 12 drives the rotating ring 92 to rotate through the first gear 13 and the second gear 14. During the rotation of the rotating ring 92, the plug board 93 can be pushed into the protective cylinder 91 through the arrangement of the inclined slot 94. The plug board 93 drives the arc-shaped triangular plate 95 to move synchronously. At this time, the three arc-shaped triangular plates 95 will move closer to the center of the protective cylinder 91 until the three arc-shaped triangular plates 95 close one end of the connecting cylinder 96, which can prevent external dust from entering the charging gun seat during charging operations and avoid dust accumulation from affecting the charging performance. Similarly, after charging is completed, only need to control the rotating ring 92 to reverse. At this time, under the action of the buffer spring 98, the plug board 93 can make the three arc-shaped triangular plates 95 move away from each other until they return to the initial state as Figure 4 shown. Then, the operator can insert the charging gun 10 into the protective cylinder 91. At this time, the sealing cover 11 will tightly cover the other end of the connecting cylinder 96 for sealing.

[0039] At the same time, the content not detailedly described in this specification belongs to the well-known prior art of those skilled in the art.

[0040] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
