It can charge various models of electric vehicles according to different voltage levels.

[0003] Regular inspection and maintenance of charging piles in use is one of the necessary tasks. In the existing inspection, the waterproofness or water tightness of the charging gun cannot be directly checked. The waterproofness is judged comprehensively through customer feedback and the appearance deformation of the external connector of the charging gun. If the waterproofness is poor and it is easy to leak, the plastic external connector is replaced; this inspection method is not accurate enough and the extent of the leakage is unclear.

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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.

[0029] Combine the following Figure 1-Figure 4 The embodiment shown describes the technical solution of the utility model:

[0030] The utility model provides a charging pile maintenance device, such as Figure 1-3 As shown, it includes: a body 1, an access head 2, a first induction ring 4, a second induction ring 5, a third induction ring 6, a humidity sensor, a central processing unit and an alarm unit 7, wherein the body 1 is formed with an access cavity 3, and the access cavity 3 is used to receive the insertion of the charging gun; the access head 2 is arranged in the access cavity 3, and is used to cooperate with the gun head of the charging gun; the first induction ring 4 is arranged at the bottom of the access cavity 3; the second induction ring 5 is arranged at the opening of the access cavity 3; there are multiple third induction rings 6, which are respectively arranged in the jack of the access head 2; there are multiple humidity sensors, and the number is consistent with the number of induction rings, which are electrically connected to the first induction ring 4, the second induction ring 5 and the third induction ring 6 respectively; the central processing unit is electrically connected to the humidity sensor; the alarm unit 7 is electrically connected to the central processing unit.

[0031] In this embodiment, the access cavity 3 and the access head 2 are restored in a one-to-one ratio according to the charging head of the electric vehicle and use the same material; the first induction ring 4, the second induction ring 5 and the third induction ring 6 are all made of the same material as the induction strip (i.e., the detection probe) of the humidity sensor, and the resistivity changes after absorbing moisture. Its essence is to extend the detection probe of the humidity sensor to the entire access cavity 3.

[0032] In this way, the moisture humidity change of the access cavity 3 can be detected, and then it can be further determined whether water has entered; the humidity sensor adopts a resistive humidity sensor; the central processing unit can adopt a single-chip microcomputer; the alarm unit 7 adopts an alarm light with a controller.

[0033] The charging pile inspection device provided by the embodiment of the utility model can restore the charging plug of the electric vehicle in a one-to-one ratio by opening an access cavity 3 on the body 1 and arranging an access head 2 in the access cavity 3, and then the charging gun can be fully inserted, thereby highly restoring the state of the electric vehicle during charging; by installing a first induction ring 4 at the bottom of the access cavity 3, the initial water leakage after the charging gun is inserted can be detected; by installing a second induction ring 5 at the opening of the access cavity 3, the intermediate water leakage after the charging gun is inserted can be detected, that is, at this time the water seepage has reached the entire access cavity 3; by setting the third induction ring 6, it can be detected whether the water seepage has reached the inner hole of the access head 2; by setting the humidity sensor, the data of each induction ring can be transmitted to the central processing unit in real time, and the central processing unit can further control the alarm unit 7 to alarm.

[0034] According to the charging pile maintenance device provided by the embodiment of the utility model, Figure 4 As shown, the body 1 has at least one arc-shaped inclined surface 101 , and the access cavity 3 is opened on the arc-shaped inclined surface 101 .

[0035] In this embodiment, the body 1 is divided into two parts, the upper part has an arc-shaped inclined surface 101, and the interior is a cavity that can accommodate circuit boards, etc.; the lower part is a cabinet that can store water tanks, water pumps, etc.; the purpose of opening the access cavity 3 on the arc-shaped inclined surface 101 in this embodiment is to restore the side shape of the electric vehicle, and then better restore the insertion angle of the charging gun, and discuss the waterproof condition of the charging gun at this angle.

[0036] According to the charging pile maintenance device provided by the embodiment of the utility model, Figure 4 As shown, it also includes: a spray head 8 and a water pump. The spray head 8 is arranged just above the access cavity 3 and is used to spray water at the access head 2. The spray head 8 is provided with a solenoid valve, which is electrically connected to the central processing unit. The body 1 has at least one water storage cavity 102, which is connected to the spray head 8 through a water pump, and the water pump is electrically connected to the central processing unit.

[0037] In this embodiment, the sprinkler head 8 is installed on the upper part of the body 1, and is connected to the water storage chamber 102 opened at the lower end of the body 1 or the water tank placed in the cabinet through a pipe. Of course, a water pump should be arranged between the two. The water pump and the solenoid valve are electrically connected to the central processing unit. When the detection is started, the water pump starts working and the solenoid valve opens; otherwise, the water pump stops working and the solenoid valve closes; in this way, the waterproof condition of the charging gun on a rainy day can be simulated.

[0038] According to the charging pile maintenance device provided by the embodiment of the utility model, Figure 1 As shown, it also includes: a control panel and a display, which are both arranged on the body 1 and electrically connected to the central processing unit respectively.

[0039] In this embodiment, the control panel and the display are both mounted on the arc-shaped inclined surface 101 for easy observation, and can display the current humidity conditions in real time. When in use, the humidity sensor is first calibrated, that is, the humidity value of the current air environment is detected without water spraying, and this is used as a reference value. After the water spraying operation starts, if the humidity sensor detects an obvious humidity change within the normal charging time period (generally within 4 hours), it is determined that water has infiltrated, and an alarm is triggered.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
