As an embodiment of the invention, a limit plate 6 is fixedly arranged on the inner wall of the left side of the charging pile main body 1; the outer wall of the limiting plate 6 is provided with a slide way 61, the slide way 61 is arc-shaped, and the slide way 61 can accommodate the plug 5; the during operation, insert the arrangement hole 2 through plug 5, through fixed mounting limiting plate 6 on the lateral wall at the 2 not movable mounting dust guard 3 in arrangement hole, can insert the in-process at plug 5 through limiting plate 6, restrict plug 5 position, avoid 5 off tracking of plug, and simultaneously, slide 61 has been seted up through the outer wall at limiting plate 6, slide 61 is circular-arc, slide 61 can hold plug 5, limiting plate 6 can further carry on spacingly to plug 5, avoid plug 5 to curl the extrusion in arrangement hole 2 inside.
The specific working process is as follows:
the dust-proof boards 3 are movably installed on the inner walls of the top and the bottom of the placing hole 2, the dust-proof boards 3 are arranged into the straight boards 31 and the vertical boards 32, the plug 5 is not inserted into the placing hole 2, the straight boards 31 on the two dust-proof boards 3 are attached together, dust and rainwater are prevented from entering the charging pile body 1 through the placing hole 2, when the plug 5 is required to be inserted into the placing hole 2, because the dust-proof boards 3 are movably installed on the placing hole 2 and are connected with the charging pile body 1 through elastic elements, when the plug 5 is inserted into the placing hole 2, the straight boards 31 on the dust-proof boards 3 are pushed by the plug 5 to deflect, the upper straight board 31 rotates anticlockwise, the lower straight board 31 rotates clockwise, because the straight boards 31 and the vertical boards 32 are connected together, the vertical boards 31 deflect along with the pushing of the straight boards 31, the vertical boards 32 can also deflect synchronously, and the vertical boards 32 can gradually press close to the surface of the plug 5, until the vertical plate 32 contacts with the surface of the plug 5, the vertical plate 32 is attached to the plug 5, so that the placing hole 2 is closed, dust and rainwater are prevented from entering the charging pile main body 1 through the placing hole 2, after the plug 5 leaves the placing hole 2, the two straight plates 31 return to the initial positions under the action of the elastic element 4 and are attached together again, and the effect of ensuring the cleanness of the interior of the charging pile main body 1 is achieved; the diameter of the spring 41 at the bottom is larger than that of the spring 41 at the top by the two springs 41 with different diameters, after the plug 5 is inserted into the dust-proof plate 3, the spring 41 at the upper part will contract first, that is, the straight plate 31 at the upper part will deflect first, thus saving the force required for inserting the plug 5, meanwhile, the spring 41 is adopted to replace the elastic rope 42, the effect of the elastic restoring force can be provided by utilizing the spring 41 after the compression, after the plug 5 leaves the placing hole 2, the straight plate 31 at the upper part can automatically restore under the action of the spring 41, avoiding the complication of manual restoration because the elastic rope 42 does not drive the straight plate 31 to restore after being adopted, meanwhile, the diameter of the spring 41 at the bottom is larger than that of the spring 41 at the top, the larger the diameter of the elastic 41 is, the larger the force required for compression or tensile deformation is also larger, therefore, the spring 41 at the upper part can be supported by the spring 41 at the lower part, the effect of ensuring the automatic resetting of the upper straight plate 31 is achieved; after the plug 5 is inserted into the placement hole 2, the vertical plate 32 is attached to the outer wall of the plug 5, and the fixture block 322 is matched with the groove 51 formed in the outer wall of the plug 5, so that the plug 5 is engaged with the fixture block 322, at the moment, the plug 5 and the fixture block 322 are engaged into a whole, the plug 5 is ensured not to fall out of the placement hole 2, meanwhile, the plug 5 and the vertical plate 32 form a closed whole to block the placement hole 2, dust and rainwater are prevented from entering the charging pile main body 1, and the effect of ensuring that the plug 5 cannot be loosened is achieved; through having seted up the circular arc chamfer on fixture block 322 left side, fixture block 322 is smooth material and makes, and after riser 32 and plug 5 laminated, fixture block 322 on riser 32 did not enter into the recess 51 that the outer wall of plug 5 was seted up, through the circular arc chamfer of seting up on fixture block 322, can make fixture block 322 drive riser 32 carry out micro-movement for fixture block 322 enters into recess 51, has reached the effect of guaranteeing that fixture block 322 can mesh with the recess 51 that the outer wall of plug 5 was seted up.
Compared with the prior art, the invention has the advantages of dustproof effect, and the experimental steps are as follows: taking a charging pile in the prior art and the charging pile as experimental instruments, preparing two groups of activated carbon with the same size and weight, weaving the activated carbon into a circular ring shape, sleeving the activated carbon on charging plugs of the two charging piles, and enabling activated carbon particles in the circular ring of the activated carbon to continuously move and rub through a driving device, so that the activated carbon generates electrostatic adsorption, and the adsorption of the activated carbon to micro particles is enhanced;
the electric pile is placed respectively in different airtight environment with two sets of electric piles, blows in through the arrangement hole with prepared flock and iron fillings through the forced draught blower, utilizes flock and iron fillings simulation dust through the arrangement hole, need guarantee twice measurement in the weight of flock and iron fillings the same, treat after the forced draught blower blows off flock and iron fillings are whole, take out the active carbon ring on the plug, add the weight to two sets of active carbon and carry out the comparison.
Twenty groups of experiments are carried out on the two instruments respectively to obtain an average value of weight increase for drawing a table, and twenty groups of data are summarized to form a line graph;
as can be seen from the above block diagram and fig. 5 and 6, the dust is more effectively prevented from entering the plug after the plug is inserted, and through the analysis of fig. 6, after a plurality of sets of experimental demonstration are carried out, the dust blocking effect of the plug is more stable than that of the prior art, so that the plug is an improvement over the prior art.
