The new energy automobile refers to all other energy automobiles except gasoline and diesel engines, including electric automobiles, hybrid electric automobiles, natural gas automobiles, hydrogen energy power automobiles, solar energy automobiles and the like. Compared with the huge population of China, China is a country seriously lack of fossil energy, and gasoline, diesel oil and natural gas can meet the requirements only by relying on import. Therefore, natural gas vehicles are not the direction of new energy vehicles that our country has particularly encouraged. Although hydrogen is pollution-free and generates a large amount of energy during combustion, the cost of hydrogen is too high for the current technology, and the application range of the hydrogen is limited. Although a few areas such as Xinjiang have abundant solar energy, China is not a country with abundant solar energy on the whole, and some areas have more rainy weather which can last for ten days. Therefore, on the whole, although the solar automobile is environment-friendly and pollution-free, the energy source of the solar automobile can not be effectively guaranteed, and the popularization and application of the solar automobile are greatly limited. Therefore, the electric automobile has more practical significance in various new energy automobiles for China. Therefore, electric vehicles are greatly supported by policies in China, and charging equipment such as a plurality of charging stations are successively established in various places.
The charging pile is important equipment for charging the electric automobile, is increasingly widely applied to places such as charging stations, parking lots, communities and the like, and is also used for building more planned electric automobile charging supporting facilities in various places. An important obstacle in popularization and application of electric vehicles is that user experience is poorer than that of common gasoline vehicles. The gasoline car can be conveniently and quickly refueled, and the refueling process is carried out
Fill inside various electric elements that are equipped with of electric pile, have the sensitivity of stronger temperature, humidity and air cleanliness factor. If the humidity in the charging pile is too high for a long time, the insulating property of the electrical equipment inside the charging pile may be reduced. The dust may cause electrical failures such as short circuits. The proper working temperature can ensure that the electrical equipment can stably work for a long time. Therefore, the industry has requirements on the temperature, humidity and cleanliness of the interior of the charging pile, and Shenzhen is a standardized instructional technical document for the charging pile, namely technical Specifications of electric vehicle charging systems. If can keep filling the interior clean dust of electric pile few, temperature and humidity can keep in the best temperature interval for a long time, then fill the job stabilization nature and the life of electric pile and all will prolong greatly, improve the user experience that electric automobile charges, reduce long-term use cost, provide supporting helping hand for electric automobile's rapid development.

The invention has the following advantages:
the invention can keep clean and less dust in the charging pile, so that the temperature and the humidity in the charging pile are kept in an optimal interval for a long time, particularly, the relative humidity in the charging pile is controlled between 45% and 75%, and the temperature is controlled between 18 ℃ and 25 ℃, thereby greatly prolonging the working stability and the service life of the charging pile, improving the user experience of charging of the electric automobile, reducing the long-term use cost, and providing the matched assistance for the rapid development of the electric automobile.
The anti-theft mechanism and the humidity control dustproof mechanism are organically combined together. When a thief steals the charging pile, the foundation bolt must be unscrewed from the mounting plate, and the anti-theft air outlet cover must be opened firstly. When the theftproof goes out the fan housing and lifts, under reset spring's effect, go up the current conducting plate and push up with lower current conducting plate together, alarm circuit automatic switch-on, buzzer and flashing lamp begin to send buzzing sound and send scintillation light, produce the fright effect to the thief on the one hand, remind staff and masses on every side on the one hand to it is stolen to prevent to fill electric pile.
The humidity control dustproof mechanism can keep the temperature in the charging pile shell within the optimal working temperature range through a constant temperature method. In the case of ventilation, the temperature inside the housing has a tendency to converge with the temperature and humidity of the ambient air. However, since the specific conditions inside and outside the housing are different (there is a possibility that heat is generated in the housing), it is difficult to completely match the temperature and humidity inside and outside the housing even if ventilation is continued. Therefore, if the ambient temperature and humidity are completely the same as the temperature and humidity inside the casing, the fan is turned off, which may cause a situation in which the fan is operated for a long time and cannot be stopped. According to the method, when the difference between the ambient temperature and the temperature and humidity in the shell is smaller than a certain range (the difference between the temperature difference is 0.5 ℃ and the relative humidity is 1%), the fan is closed, the temperature and humidity conditions in the shell can be kept in the optimal range, and the defect that the running time of the fan is too long can be overcome.
The charging pile combines the constant temperature method and the constant humidity method, only when the temperature or humidity condition of the environment is superior to that of the shell, the ventilation is carried out through the fan, the ambient air enters from the air inlet and flows out from the air outlet, and therefore refrigeration or heating is not needed by using electric power, a drying agent or electric power for dehumidification is not needed, and electric power for drying is not needed, so that the energy consumption and the equipment loss are reduced. When the temperature or humidity condition of the environment is inferior to that in the shell, the invention can not suck air from the outside any more, but carries out dehumidification operation by the moistureproof annular pipe, and uses the semiconductor refrigeration and heating sheet to refrigerate or heat so as to adjust the humidity and the temperature.
The constant temperature method and the constant humidity method are selective methods, and when one of the constant temperature method and the constant humidity method is in an operating state, the other method is not started, so that the situation that the constant temperature method and the constant humidity method have contradictory instructions for the operation of components such as the two-position three-way electromagnetic valve and the like and any method cannot be effectively executed is avoided. The constant temperature method and the constant humidity method are not executed simultaneously, so that the constant temperature method and the constant humidity method can obtain effective results in respective execution processes.
The theftproof goes out the fan housing and has two functions simultaneously: one is to automatically switch off or switch on the alarm circuit through gravity (namely, the alarm circuit is automatically switched off under a normal working state, and the alarm circuit is automatically switched on to give an alarm when a person lifts the anti-theft air outlet cover), and the other is to change the air outlet direction, so that the air outlet is prevented from directly facing the ground and blowing the ground. If the dust sweeping device directly sweeps the ground, when the dust sweeping device works, when the dust in the environment is more, the dust flying state can occur near the charging pile, so that the use experience of a user is reduced, the filter screen is stressed greatly, and the dust accumulation speed at the filter screen is accelerated.
The rain shade can prevent outside water (such as rainwater or water) from entering the anti-theft air outlet cover through the air outlet hole.
The semiconductor refrigerating and heating sheet for refrigerating is positioned at the top of the shell, the semiconductor refrigerating and heating sheet for heating is positioned at the bottom of the shell, cold air is easy to fall, hot air is easy to rise, and therefore natural convection is formed in the shell by utilizing the density difference of the cold air and the hot air, and cold or heat can be smoothly transmitted to all parts inside the shell.
The moisture-proof air outlet pipe and the inner circulation air pipe are positioned on the two opposite side walls of the inner wall of the shell, so that the phenomenon of short circuit of air flow caused by too close distance between the air inlet and the air outlet of the air path in the inner circulation mode can be avoided, and the inner circulation dehumidification effect can be better played.
The anti-blocking back blowing mechanism and the anti-blocking method blow air onto the filter screen from inside to outside through the nozzle structure, and utilize factors such as airflow disturbance and vibration to enable the nozzle structure and the hollow plate to be subjected to unstable reaction force, so that the nozzle structure and the hollow plate rotate around the hollow shaft to blow the filter screen everywhere, dust and sundries at all places of the filter screen are subjected to back blowing removal, and the filter screen can be effectively prevented from being blocked by the dust or the sundries.
The setting of porous disk and the groove of permeating water for when external water flies to spill into the exhaust vent such as rainy day, can catch external water, and go out the water drainage through the groove of permeating water, avoid the theftproof to go out ponding in the fan housing, prevent to intake in the theftproof recess and lead to electrical fault, prevent simultaneously to lead to filling the increase of electric pile casing internal humidity because of the theftproof goes out ponding in the fan housing.
The arrangement of the water receiving tank and the water discharging pipe can timely discharge a small amount of condensed water generated under special conditions (only when the humidity in the shell is high for a long time, the temperature reduction and dehumidification are needed).
The main guide rod and the auxiliary guide rod form a structure similar to a branch and are metal rods. The water vapor in the air is easily condensed on the main guide rod and the auxiliary guide rod when being condensed, then flows downwards to the ventilation hole along the main guide rod, and falls into the water receiving tank downwards through the ventilation hole. Therefore, most of the condensed water can be concentrated at the main guide rod and the auxiliary guide rod, and the condensed water is favorably led out.
The buzzer is located at the bottom in the air inlet box, so that the buzzing alarm sound sent by the buzzer can be transmitted out from the air inlet on the one hand, and on the other hand, the buzzer is located in the shell, so that a thief cannot damage the buzzer from the outside after hearing the buzzing sound, and the buzzer is ensured to work continuously. The flashing light is positioned on the top of the shell and is easier to observe, so that a warning effect is generated.
The drying method of the drying agent can dehydrate the drying agent after moisture absorption, thereby recovering the moisture absorption capacity of the drying agent, prolonging the service life of the drying agent, reducing the frequency of replacing the drying agent, not only further facilitating the use, but also reducing the maintenance cost.
