Description

Technical Field

[0001] This utility model relates to the field of power equipment maintenance technology, specifically to a device for detecting water leakage in the casing of a charging pile during maintenance. Background Technology

[0002] Charging piles, similar in function to gas pumps at gas stations, are dedicated electrical devices for charging electric vehicles. They connect to the charging interface of electric vehicles to transmit electrical energy from the power grid to the vehicle's battery. They are an indispensable infrastructure for the development of the electric vehicle industry and are known as the "gas stations" for electric vehicles.

[0003] To make charging electric vehicles more convenient, some charging stations are generally installed outdoors. In rainy or other conditions, if the outer casing of the charging station is damaged, water may seep into the charging station. If this is not detected and repaired in time, it may damage the internal equipment of the charging station. Utility Model Content

[0004] (I) Technical Issues

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a device for detecting water leakage in the outer shell of a charging pile, which can effectively solve the problem of detecting water leakage in the outer shell of a charging pile.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0008] A device for detecting water leakage in the casing of a charging pile for maintenance includes a small hole on the side of the charging pile, through which a rope passes. A hollow ball is installed at one end of the rope on the inner side of the charging pile, and a counterweight is installed at the other end of the rope on the outer side of the charging pile. The weight of the counterweight is less than that of the hollow ball. A scale is installed on the outer side of the charging pile at a position corresponding to the counterweight.

[0009] A penetration detector is installed on the outside of the charging pile. The penetration detector includes a detector housing. One end of the detector housing is connected to a suction cup via a tube. A groove is provided on the upper end of the detector housing, and a miniature vacuum pump is installed in the groove. The air inlet of the miniature vacuum pump is connected to the air outlet of the suction cup.

[0010] As an improvement, a battery compartment is provided at the bottom of the detector chassis, and a storage battery is installed in the battery compartment.

[0011] As an improvement: a handle is provided at the bottom of the detector housing on one side of the battery compartment, and a switch is provided on the side of the handle.

[0012] As an improvement: a battery cover with bolts is provided at the bottom of the detector housing corresponding to the battery slot, and the battery cover is larger than the battery slot.

[0013] As an improvement, a charging port is provided at the bottom of the detector chassis.

[0014] As an improvement, several water immersion sensors are installed on the bottom inner side of the charging pile.

[0015] As an improvement: the charging pile is equipped with a transparent cover fixed by bolts on the outside, and the small hole, counterweight and scale are all inside the transparent cover.

[0016] (III) Technical Effects

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. This utility model has a counterweight block with hollow small balls connected by ropes on both the inner and outer sides of the charging pile. When there is water seepage inside the charging pile, the hollow small balls float up and the counterweight block falls. The amount of water seepage can be determined by observing the distance the counterweight block falls with a ruler, and it can also rule out other reasons for the charging pile malfunction.

[0019] 2. This utility model also has a suction cup installed at one end of the detector housing. The suction cup is placed on the outer shell of the charging pile, and the air inside the suction cup is extracted by a micro vacuum pump. If the suction cup cannot adhere to the outer shell of the charging pile, then this is the point of damage and penetration. Attached Figure Description

[0025] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] A device for detecting water leakage in the casing of a charging station for maintenance, as shown in the instruction manual. Figure 1 , 3 As shown in Figure 4: The charging pile 1 includes a small hole 2 on its side, which is polished to a smooth finish. A rope 3, made of smooth material such as nylon rope with low friction, passes through the small hole 2. A hollow ball 4 is installed at one end of the rope 3 on the inner side of the charging pile 1, and a counterweight 5 is installed at the other end of the rope 3 on the outer side of the charging pile 1. The weight of the counterweight 5 is less than that of the hollow ball 4. A scale 6 is installed on the outer side of the charging pile 1 at a position corresponding to the counterweight 5. A transparent cover 18 fixed with bolts is installed on the outer side of the charging pile 1. The small hole 2, the counterweight 5, and the scale 6 are all inside the transparent cover 18 to reduce the influence of external factors on the rope 3. Several water immersion sensors 17 are installed at the bottom inner side of the charging pile 1. The water immersion sensors 17 are connected to the control module of the charging pile 1. When water is detected, they transmit a signal to cut off the power to the charging pile 1 to prevent water from entering and damaging the charging pile 1.

[0028] As per the instruction manual Figure 1 , 2A permeation detector is installed on the outside of the charging pile 1 shown. The permeation detector is equipped with a detector housing 7. One end of the detector housing 7 is connected to a suction cup 8 via a pipe. A groove 9 is provided on the upper end of the detector housing 7. A miniature vacuum pump 10 is installed in the groove 9. Existing technology, such as a GZO / VLC7602 brushless direct vacuum pump, is used. The air inlet of the miniature vacuum pump 10 is connected to the air outlet of the suction cup 8. A battery slot 11 is provided at the bottom of the detector housing 7. A storage battery 12 is installed in the battery slot 11. A handle 13 is provided at the bottom of the detector housing 7 on one side of the battery slot 11. A switch 14 is provided on the side of the handle 13. A battery cover 15, which is fixed with bolts, is provided at the bottom of the detector housing 7 corresponding to the battery slot 11. The battery cover 15 is larger than the battery slot 11. A charging port 16 is provided at the bottom of the detector housing 7 for charging the storage battery 12.

[0029] In the specific implementation of this embodiment:

[0030] When in use, when the counterweight 5 changes the scale on the ruler 6, it can be determined that the charging pile 1 is faulty due to water seepage. Place the suction cup 8 on different positions on the outer shell of the charging pile 1, press the switch 14 to start the micro vacuum pump 10, and find the position where the suction cup 8 can no longer be suctioned, which is the position where the outer shell is damaged and seeping.
