[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1-6 The DC charging pile with independent air duct shown in the figure includes a pile body 1, a charging gun 2 for charging is arranged on the outside of the pile body 1, and blocking mechanisms for blocking the air duct entrance are symmetrically arranged on both sides of the pile body 1. The blocking mechanism includes a shielding component and a fixing component for installing the shielding component. The shielding component includes a filter screen 5 for shielding flocs.

[0019] Specifically, the pile body 1 and the charging gun 2 constitute the existing model RSDC1000-120KW integrated dual-gun independent air duct DC charging pile. The air duct openings of the pile body 1 are opened on both sides of the bottom of the pile body 1, and the charging guns 2 are symmetrically arranged on both sides of the pile body 1.

[0020] Specifically, the fixing assembly includes a first fixing frame 3 and a second fixing frame 4, the filter screen 5 is arranged on the side opposite to the first fixing frame 3 and the second fixing frame 4, one side of the second fixing frame 4 is fixedly connected to one side of the pile body 1, and the first fixing frame 3 and the second fixing frame 4 are respectively provided with a first ventilation groove and a second ventilation groove, and the inner wall of the second ventilation groove is fixedly connected with a reinforcing rod 6, and the function of the reinforcing rod 6 is to enhance the deformation resistance of the filter screen 5.

[0021] Furthermore, the blocking mechanism is symmetrically arranged on both sides of the pile body 1, the first fixed frame 3 and the second fixed frame 4 are both rectangular frames, the first fixed frame 3 and the second fixed frame 4 have the same size, and the size is 1.3 times the total area of ​​the air duct opening on one side of the pile body 1, the first ventilation slots and the second ventilation slots of the first fixed frame 3 and the second fixed frame 4 have the same size, and the area of ​​the first ventilation slot is 1.1 times the total area of ​​the air duct opening, the reinforcing rod 6 is cross-shaped, and the four ends of the reinforcing rod 6 are respectively fixedly connected to the four inner walls of the second ventilation slot, and when the filter net 5 is blown by strong wind and rain, the middle part of the reinforcing rod 6 can support the middle part of the filter net 5 to prevent the filter net 5 from being bent and blown out of the second ventilation slot.

[0022] Specifically, pressing grooves are respectively provided at the top and bottom of the inner wall of the second ventilation groove, and a pressing piece for pressing the filter 5 is arranged inside the pressing groove. The pressing piece includes an extrusion block 8 for extruding the filter 5, and one side of the extrusion block 8 is fixedly connected with an extrusion spring 7 for pushing the extrusion block 8, and one end of the extrusion spring 7 is fixedly connected to the inner wall of the pressing groove.

[0023] Furthermore, the squeezing spring 7 pushes the squeezing block 8 to extend out of the pressing groove without being affected by pressure, so that when the first fixed frame 3 and the second fixed frame 4 are connected, the second fixed frame 4 acts on one side of the first fixed frame 3 and the squeezing block 8 to clamp the two sides of the filter screen 5. At the same time, the second fixed frame 4 pushes the squeezing block 8 to move toward the pressing groove to squeeze the squeezing spring 7. When the first fixed frame 3 no longer moves, the restoring force of the squeezing spring 7 pushes the squeezing block 8 to move away from the squeezing spring 7, but it cannot move under the restriction of the second fixed frame 4. The thrust generated on the filter screen 5 cooperates with the second fixed frame 4 to form pressure, thereby clamping the filter screen 5, firmly fixing the position of the filter screen 5, and fixing the filter screen 5. The aperture of the filter screen 5 is 0.2-0.5mm, and the side of the filter screen 5 close to the reinforcing rod 6 faces the air duct opening, and the external flocs will be blocked by the filter screen 5, and the flocs cannot enter the air duct entrance.

[0024] Specifically, a connecting piece for connecting to the first fixed frame 3 is provided on one side of the second fixed frame 4, and a connecting groove for installing the connecting piece is opened on one side of the first fixed frame 3. The connecting piece includes an insert rod 9, and the insert rod 9 is connected to the connecting groove through an insertion, and a cavity is opened at one end of the insert rod 9. The front and back sides of the inner wall of the cavity are respectively provided with insertion holes, and a block 10 for limiting the movement of the first fixed frame 3 is inserted inside the insertion hole. One end of the block 10 is fixedly connected to a baffle 11 for limiting the movement of the block 10, and one side of the baffle 11 is fixedly connected to a pushing spring 12 for pushing the baffle 11 to move.

[0025] Furthermore, at least four connecting members are provided, which are respectively provided at the four corners of the second fixed frame 4 facing the first fixed frame 3. The size of the plug rod 9 is 0.95 times the size of the connecting groove. The block 10 is a right-angled triangular prism. The inclined surface of the block 10 faces the side away from the second fixed frame 4. The size of the baffle 11 is 1.1 times the size of the insertion hole. The pushing spring 12 is always in a compressed state in the cavity. When the block 10 is in a pop-up state, the block 10 cooperates with the plug rod 9 to form a card connection with the first fixed frame 3, so that the first fixed frame 3 and the second fixed frame 4 are tightly fitted on the opposite side. When the filter screen 5 needs to be disassembled, the block 10 is first pressed toward each other to move the block 10 into the connecting groove, and then the first fixed frame 3 is pulled to move in the direction away from the second fixed frame 4, thereby When the filter screen 5 loses pressure, the filter screen 5 can be disassembled. When installing the filter screen 5, first fit the filter screen 5 against the reinforcing rod 6, and then insert the insertion rod 9 into the connecting groove. The connecting groove will squeeze the block 10, and the block 10 will further squeeze the pushing spring 12 through the baffle 11. When the block 10 moves out of the connecting groove, the restoring force of the pushing spring 12 pushes the block 10 to move backwards, so that the block 10 is engaged with the first fixed frame 3, limiting the movement of the first fixed frame 3, completing the connection between the first fixed frame 3 and the second fixed frame 4, and realizing the replacement and installation of the filter screen 5. In this way, when it is necessary to clean the flocs, when the first fixed frame 3 is disassembled, the filter screen 5 can be disassembled, replaced or cleaned, which is very convenient and fast, saving manpower.
