Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, a charging pile with a dehumidifying function includes a housing 1, a bracket 16 for supporting the housing 1, and a plurality of electrical components 2 installed in the housing 1. An air inlet 11 is arranged on the side wall below the shell 1, and a drying pipeline 4 crossing the shell 1 is arranged in the shell 1. The drying duct 4 is provided with a drying device 6 for drying the gas, a dust removal device 7 and an exhaust fan 8. The drying pipeline 4 comprises an air inlet end 42 and an air outlet end 43, four axial flow fans 9 are mounted on the side wall of the shell 1 opposite to the air outlet end 43, an air inlet 11 is formed in the side wall of the shell 1 opposite to the air inlet end 42, and an air outlet 12 is further formed in the side wall of the shell 1 provided with the axial flow fans 9. The four axial flow fans 9 are uniformly distributed along the vertical direction. The axial flow fan 9 is electrically connected with an external power supply through a wire.

When the electrical element 2 dehumidifies, the exhaust fan 8 is turned on. The outside air and the air in the shell 1 enter the drying pipeline 4 from the air inlet end 42 under the action of the exhaust fan 8, and after impurities are removed by the drying device 6 and the dust removing device 7, the outside air crosses the shell 1 under the guidance of the drying pipeline 4 and is discharged into the shell 1 from the air outlet end 43. The drying air coming out of the drying duct 4 is blown from one side of the casing 1 to the other side of the casing 1, guided by the axial fan 9. A portion of the gas also exits the housing 1 through the gas outlet 12. Then, the gas enters the drying pipeline 4 under the action of the exhaust fan 8, is dried again by the drying device 6 and is dedusted by the dedusting device 7, and then flows out from the gas outlet end 43, so that the gas is circularly dried and dedusted in the shell 1, the gas content and impurities in the shell 1 are reduced, and the exchange between the gas in the shell 1 and the outside gas is also maintained.

Referring to fig. 2 and 3, the drying device 6 includes a drying drawer 61 detachably connected to the drying duct 4, and a drying agent 62 placed in the drying drawer 61, wherein the drying duct 4 is provided with an installation groove 41, and a side wall of the housing 1 is provided with a communication groove 13 opposite to the installation groove 41. In order to improve the ventilation efficiency of the casing 1, a drying plate 44 is fixed to the casing side wall, and the drying duct 4 is defined by the drying plate 41, the casing bottom wall, and the casing side wall. Therefore, the mounting groove 41 and the communication groove 13 overlap each other, and the bottom of the mounting groove 41 is the inner wall of the housing. The drying drawer 61 includes a placement section 611 slidably connected to the installation groove 41 in the width direction of the drying duct 4 and configured to place the drying agent 62 thereon, and a locking member 612 configured to lock the placement section 611 with respect to the drying duct 4. The placement section 611 includes a front plate 6111, two side plates 6112 fixed to two sides of the front plate 6111 in the width direction, a rear plate 6113 fixed to one end of the two side plates 6112 far away from the front plate 6111, a bottom plate 6114 fixed to the front plate 6111, the two side plates 6112, the lower end face of the rear plate 6113, and a locking plate 6115 fixed to the front plate 6111. The sectional area of the locking plate 6115 is larger than that of the communication groove 13. Sliding grooves 613 are formed in the upper ends of the two side plates 6112 and the upper end of the rear plate 6113, sliding protrusions 614 are fixed on the upper groove walls of the communication groove 13 and the mounting groove 41, and the sliding protrusions 614 are embedded and slidably connected to the sliding grooves 613 in the width direction of the drying duct 4. The two side plates 6112 are provided with a plurality of through holes 615 which are uniformly distributed.

A hook 14 is fixed on the side wall of the housing 1, and a locking piece 612 is mounted on the locking plate 6115. The locking member 612 is a buckle hinged to the locking plate 6115 and adapted to engage the hook 14. A sealing bulge 10 which is arranged in a shape of a Chinese character 'hui' is fixed on one surface of the locking plate 6115 which is connected with the front plate 6111, and a sealing groove 15 which is arranged in a shape of a Chinese character 'hui' and corresponds to the sealing bulge is arranged on the side wall of the shell 1. A sealing ring 3 which is arranged in a shape like a Chinese character 'hui' is fixed in the sealing groove 15. The sealing bulge 10 is in transition fit with the sealing ring 3.

When the drying drawer 61 is installed, the sliding protrusion 614 is fitted to the sliding groove 613, and the sliding protrusion 614 is inserted into the sliding groove 613. In this manner, the drying drawer 61 is slid into the mounting groove 41 after passing through the communication groove 13 in the width direction of the drying duct 4. When the rear plate 6113 of the drying drawer 61 abuts against the inner wall of the drying duct 4, the drying drawer 61 reaches the maximum position. At this time, the sealing protrusion 10 extends into the sealing groove 15, and the sealing protrusion 10 is engaged with the sealing ring 3. The lock plate 6115 abuts against the side wall of the housing 1. The hasp is rotated upward to be sleeved on the hook 14. In this way, the relative positions of the drying drawer 61 and the housing 1 are locked. The drying device 6 is ensured to work, and the drying drawer 61 cannot shake due to external factors.

As shown in fig. 1, the dust removing device 7 includes an ash bucket 71 communicating with a lower portion of the drying duct 4, a baffle plate 72 fixed to an inner wall of the drying duct 4 above the ash bucket 71, and an ash discharge valve 73 attached to the ash bucket 71. Due to the difference in inertia forces between the impurities and the gas during movement, the baffle 72 is disposed in front of the dusty gas stream, causing the direction of the gas stream to change abruptly. At this time, the dust particles are separated from the gas flow and discharged after the gas obtained by purification changes its direction sharply because the inertia force is much larger than that of the gas. The velocity of the settling gas through the enlarged cross-section decreases and the larger particles of solids settle first by colliding with the baffle 72 and the smaller particles settle in the next hopper 71. The operator needs to open the ash discharge valve 73 periodically to clean the ash hopper 71.

The working principle is as follows: when the electrical element 2 dehumidifies, the outside air and the air in the housing 1 enter the drying duct 4 from the air inlet 11 under the guide of the exhaust fan 8, pass through the side plate 6112 on one side, enter the drying agent 62 for drying, pass through the through hole 615 on the side plate 6112 on the other side, and enter the dust removing device 7. When the gas passes through the ash bucket 71, impurities in the gas settle in the ash bucket 71 due to inertia. Thereby filtering the gas. The gas is then discharged from the other end of the drying duct 4 into the interior of the housing 1. The drying air from the drying duct 4 is guided by the axial fans 9 and blown from one side of the casing 1 to the air inlet end 42 side of the drying duct 4. The gas is then passed through 5 into the drying tunnel 4 by means of an exhaust fan 8, where it is dried and dedusted again. This is repeated to reduce the water content of the gas in the casing 1 and to achieve the ventilation effect.

The operator needs to regularly replace the drying agent 62 in the drying drawer 61 to maintain the drying efficiency of the drying device 6. The ash discharge valve 73 is also opened periodically to clean the ash hopper 71.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
