Description

Technical Field

[0001] The utility model relates to the technical field of dustproof devices, and more specifically, to a dustproof device for a charging pile. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in parking lots or charging stations in public buildings and residential areas. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] At present, electric vehicle charging piles generate a lot of heat during operation, and a heat dissipation device is needed to dissipate the heat of the charging piles. However, traditional heat dissipation methods can easily bring dust in the air into the charging piles, which greatly increases the safety risks of the charging piles. Although some heat dissipation devices are equipped with dust-proof devices such as filters, if the dust accumulated on the surface of the filters is not cleaned for a long time, it will also affect the heat dissipation effect of the charging piles. Utility Model Content

[0011] do

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. In the utility model, by pulling out the sealing block, the four upper electromagnets are energized in the reverse direction to generate a magnetic field that repels the permanent magnet, causing the filter plate to fall downward, and at the same time, the four lower electromagnets are powered off, the telescopic rod is extended, and the lower filter plate is moved upward. When the lower filter plate moves to the uppermost end, the four upper electromagnets are energized in the forward direction to generate an adsorption magnetic field, which adsorbs the permanent magnet to temporarily fix the filter plate to the left plate. After the upper filter plate falls to the bottom, the dust will be shaken off, and at the same time, the four lower electromagnets are energized to generate an adsorption magnetic field, which adsorbs the permanent magnet to move the filter plate to the left and temporarily fix it to the left plate, thereby completing the replacement of the upper and lower filter plates. The fan continues to work, and will blow off the dust and impurities on the left side of the upper filter plate before replacement, thereby ensuring the cleanliness of the filter plate, thereby solving the problems of poor dust prevention and heat dissipation effects of traditional charging piles.

[0014] 2. In the utility model, by pulling out the sealing block, the four upper electromagnets are reversely energized, and the four lower electromagnets are de-energized, so that the upper filter plate falls downward along the inner wall of the back shell, and the telescopic rod is extended to move the lower filter plate upward, so that the positions of the two are swapped, and the internal air discharge will blow the impurities that block the filter plate back into the air, thereby solving the problem that the filter plate of the existing air inlet hole is blocked, while the exhaust hole is still in a relatively clean state. When used for a long time, the service life of the two filter plates will be different and multiple replacements are required. At the same time, the replacement of the two filter plates also solves the problem that the existing fine impurities block the filter plate and are difficult to clean.

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.

[0024] like Figures 1 to 7As shown, the embodiment of the utility model provides a dustproof device for a charging pile, including a charging pile 1, a display screen 2, an emergency stop button 3, a card swiping area 4, and a gun seat 5 are installed on the front of the charging pile 1, a card hole 6 is opened in the middle of the front of the gun seat 5, a charging gun 7 is clamped in the middle of the card hole 6, and the end of the charging gun 7 away from the card hole 6 is fixedly connected to the inside of the charging pile 1, a left side plate 8 is clamped on the left side of the charging pile 1, a rectangular hole 9 and a plurality of air holes 10 are opened in the middle of the left side plate 8, a plurality of electromagnets 11 are fixedly installed in the inside of the left side plate 8, and the right side of the left side plate 8 is fixed A back shell 12 is connected, an air inlet 13 and an exhaust hole 14 are opened on the right side of the back shell 12, two telescopic rods 15 are fixedly installed on the front and rear sides of the bottom of the back shell 12, a limiting mechanism 16 is fixedly installed in the middle of the back shell 12, two filter plates 17 are arranged in the middle of the right side of the left side plate 8, four corners of the filter plate 17 are fixedly connected with permanent magnets 20, and the front and rear sides of the filter plate 17 are fixedly connected with protrusions 21, a fan 18 is fixedly installed on the right side of the air inlet 13, and a sealing block 19 is slidably connected to the middle of the rectangular hole 9, and its function is to stop the fan 18 from working. The sealing block 19 is pulled out, and the four electromagnets 11 on the upper part are energized in the reverse direction to generate a magnetic field that repels the permanent magnet 20, causing the permanent magnet 20 to move to the right and contact the inside of the back shell 12, and then fall downward. At the same time, the four electromagnets 11 on the lower part are powered off, and the telescopic rod 15 is extended to move the filter plate 17 below upward. When the protrusions 21 on both sides of the filter plate 17 contact the trapezoidal block 163, the trapezoidal block 163 will be pushed to move close to the installation cavity 161, which will squeeze the compression spring 162. When the filter plate 17 below moves to the uppermost end, the four electromagnets on the upper part 11 is energized in the forward direction to generate an adsorption magnetic field, which adsorbs the permanent magnet 20 to temporarily fix the filter plate 17 to the left plate 8. After the upper filter plate 17 falls to the bottom, the dust will be shaken off. At the same time, the four electromagnets 11 below are energized to generate an adsorption magnetic field, which adsorbs the permanent magnet 20 to move the filter plate 17 to the left and temporarily fix it to the left plate 8, thereby completing the replacement of the upper and lower filter plates 17. The fan 18 continues to work, and the sealing block 19 is pushed back, which will blow off the dust and impurities on the left side of the upper filter plate 17 before replacement, thereby ensuring that the left side of the filter plate 17 becomes clean.

[0025] Among them, the limiting mechanism 16 includes an installation cavity 161, and a compression spring 162 is fixedly connected inside the installation cavity 161. The end of the compression spring 162 away from the installation cavity 161 is fixedly connected to a trapezoidal block 163. The trapezoidal block 163 is movably connected to the installation cavity 161, and the installation cavity 161 is fixedly connected to the back shell 12. Its function is that when the protrusions 21 on both sides of the filter plate 17 contact the trapezoidal block 163, the trapezoidal block 163 will be pushed to move closer to the installation cavity 161 to squeeze the compression spring 162; when the trapezoidal block 163 is extended, it ensures that the upper filter plate 17 will contact the back shell 12 before falling.

[0026] Among them, the right side of the sealing block 19 is in contact with the inside of the back shell 12, and the sealing between the sealing block 19 and the back shell 12 is good. The left side of the trapezoidal block 163 does not contact the left side plate 8. The right side of the trapezoidal block 163 is vertically flush with the left side of the filter plate 17. Two blocks are provided inside the back shell 12, and the blocks are horizontally flush with the top of the telescopic rod 15. A rectangular baffle is provided on the outside of the telescopic rod 15.

[0027] Working principle:

[0028] In this embodiment, when the charging pile 1 is working normally, in order to ensure that the temperature of the internal electronic components is normal, the fan 18 works, sucks the external air into the charging pile 1, and the air passes through the air vent 10, the upper filter plate 17, and the air inlet 13, and finally cools the electronic components inside the charging pile 1. After the air circulates inside the charging pile 1, it takes away the heat and is discharged from the exhaust hole 14, the lower filter plate 17, and the air vent 10. Due to the setting of the upper filter plate 17, the dust and impurities in the air are filtered on the right side of the upper filter plate 17, thereby preventing the air entering the charging pile 1 from interfering with the electronic components of the charging pile 1 or even burning them;

[0029] After a long period of filtration, the upper filter plate 17 has a lot of dust and impurities on the left side of the upper filter plate 17. At this time, the fan 18 stops working, the sealing block 19 is pulled out, and the four upper electromagnets 11 are energized in the reverse direction to generate a magnetic field that repels the permanent magnet 20, causing the permanent magnet 20 to move to the right and contact the inside of the back shell 12, and then fall downward. At the same time, the four lower electromagnets 11 are powered off, and the telescopic rod 15 is extended to move the lower filter plate 17 upward. When the protrusions 21 on both sides of the filter plate 17 contact the trapezoidal block 163, the trapezoidal block 163 will be pushed to move close to the installation cavity 161, which will squeeze the compression spring 162. When the upper filter plate 17 moves to the uppermost end, the four upper electromagnets 11 are energized in the forward direction to generate an adsorption magnetic field, which adsorbs the permanent magnet 20 to temporarily fix the filter plate 17 to the left plate 8. After the upper filter plate 17 falls to the bottom, the dust will be shaken off. At the same time, the four lower electromagnets 11 are energized to generate an adsorption magnetic field, which adsorbs the permanent magnet 20 to move the filter plate 17 to the left and temporarily fix it to the left plate 8, thereby completing the replacement of the upper and lower filter plates 17. The fan 18 continues to work, and the sealing block 19 is pushed back, which will blow off the dust and impurities on the left side of the upper filter plate 17 before the replacement, thereby ensuring that the left side of the filter plate 17 becomes clean.
