Connection; the first motor 2 controls the rotation of the drive shaft 16 and the disc 8; a fixed cylinder 17 is fitted above the disc 8, and the top of the fixed cylinder 17 is fixedly connected to the housing 1; three isolation plates 13 are fixed at equal angles on the outer wall of the fixed cylinder 17, giving the chamber an independent environment for different operations. The isolation plates 13 can block the movement between the chambers and divide the housing 1 and the disc 8 into three cavities: a test chamber 11, a drying chamber 12, and a loading chamber 7; the test chamber 11 can be used for charging piles. After a waterproof test, the drying chamber 12 performs the next drying process, and finally the charging pile is removed from the loading chamber 7. Fixing devices 9 are installed in the testing chamber 11, drying chamber 12, and loading chamber 7 to fix the charging pile for testing. Fixing the charging pile allows for better coordination with the device to complete the test. An automatic opening and closing isolation device 10 is provided; the isolation plate 13 has a rectangular groove 14 in the middle, and the automatic opening and closing isolation device 10 is slidably connected to the isolation plate 13 at the rectangular groove 14. Through the automatic opening and closing isolation device 10, the charging pile can pass through the isolation as the disc 8 rotates. After leaving panel 13, proceed to the next chamber, the water spray test device 21. The housing 1 is located on top of the test chamber 11 and is equipped with the water spray test device 21. The water spray test device 21 includes a water tank 5, which can be used to store water for the water spray test device 21. A tray 4 is fixedly connected to the lower part of the outer wall of the housing 1. The water tank 5 is located on top of the tray 4. The water tank 5 is connected to one end of a water pump and a water suction pipe 6. The water pump can draw water from the inside of the water tank 5 and transfer it to the water spray test device 21 for repeated use. The other end of the water suction pipe 6 extends through the top of the housing 1 into the interior of the test chamber 11.
[0023] The fixing device 9 includes a chassis 901, which is fixedly connected to the surface of a disc 8. A placement disc 902 is rotatably connected to the chassis 901 and is used to support the charging pile. A second motor 20 is fixedly connected below the disc 8. The output shaft of the second motor 20 is fixedly connected to the placement disc 902. The second motor 20 can rotate the placement disc 902, thereby controlling the rotation of the charging pile. Multiple sets of parallel sliding grooves 903 are formed on the surface of the placement disc 902. A first spring 904 is fixedly connected to the top of the inner wall of the sliding groove 903. Card holders 905 are arranged opposite to each other at both ends of the placement disc 902. The card holders 905 can fix the charging pile through the spring mechanism. Multiple sets of sliding shafts 906 are fixedly connected to the bottom of one set of card holders 905. The sliding shafts 906 are distributed inside the sliding grooves 903. The sliding shafts 906 and the sliding grooves 903 are used to guide the card holders 905 when they are pulled. The top of the sliding shafts 906 is fixedly connected to the first spring 904.
[0024] The surface of the disc 8 is provided with multiple drainage holes 15. During the waterproof test of the charging pile, the water sprayed by the water spray test device 21 can flow out through the drainage holes 15.
[0025] A guide plate 18 is provided below the disc 8. The outer wall of the guide plate 18 is fixedly connected to the inner wall of the shell 1. The guide plate 18 is inclined to the horizontal plane. When water flows out through the drain hole 15, it will enter and fall onto the surface of the guide plate 18. Due to the angle of inclination of the guide plate 18, the water will eventually be collected in one place inside the shell 1.
[0026] A return water pipe 19 is fixedly connected to the outer surface of the water tank 5. The other end of the return water pipe 19 is fixed to the inner cavity of the shell 1 between the disc 8 and the guide plate 18. The water tank 5, the return water pipe 19 and the shell 1 are internally connected. The return water pipe 19 can introduce the water collected by the guide plate 18 into the water tank 5 to realize the repeated use of water resources.
[0027] The automatic opening and closing isolation device 10 is arranged in a circular array on the surface of the isolation plate 13 on one side inside the feeding chamber 7, the testing chamber 11, and the drying chamber 12. This allows the charging pile to rotate via the disc 8 to reach the isolation plate 13 of each chamber without obstruction. The automatic opening and closing isolation device 10 includes a slide rail 1003, which is formed on the surface of the isolation plate 13. A baffle 1001 is positioned opposite to one end of the slide rail 1003, sealing and isolating each chamber. A slider 1002 is fixedly connected to one end of the baffle 1001. 1. The slider 1002 is slidably connected to the slide rail 1003 on the outer surface of the isolation plate 13, which can realize the opening and closing control of the rectangular groove 14 on the isolation plate 13. A second fixing block 1004 is fixedly connected to the surface of the isolation plate 13. A second spring 1005 is fixedly connected to the opposite sides of the baffle 1001. The end of the second spring 1005 away from the baffle 1001 is fixedly connected to the second fixing block 1004. The second fixing block 1004 is fixedly connected to the isolation plate 13. Through the rebound force of the second spring 1005, the baffle 1001 can be automatically closed after it is opened.
[0028] The outer wall of the chassis 901 is designed in the shape of a teardrop. The top of the baffle 1001, which is away from the isolation plate 13, is provided with a diamond-shaped groove 1006. Through the ingenious design of the teardrop shape, it abuts into the diamond-shaped groove 1006 below the baffle 1001. As the disc 8 continues to rotate, the chassis 901 pushes the baffle 1001 open to both sides. At this time, the baffle 1001, through the cooperation of the slider 1002 and the slide rail 1003, moves parallel to both sides in opposite directions, completing the opening movement of the two baffles 1001.
[0029] Working principle: During use, pull outwards the clamp 905 with sliding shaft 906 inside the loading chamber 7. The first spring 904 in the slide groove 903 is stretched, placing the charging pile on the placement tray 902. Slowly release the clamp 905, and at the same time, the first spring 904 returns to its original position, thus clamping the charging pile between the clamps 905 at both ends of the placement tray 902, completing the fixing of the charging pile. Start the device, and the first motor 2 drives the transmission shaft 16 and the disc 8 to start rotating. The fixing device 9 on the disc 8 also rotates accordingly. At the same time, the second motor 20 starts to rotate, causing the charging pile above the placement tray 902 to start rotating. When the charging pile approaches the automatic opening and closing isolation device 10 on the isolation plate 13, the outer side of the lower chassis 901, through a clever teardrop-shaped design, abuts into the diamond groove 1006 below the baffle 1001. As the disc 8 continues to rotate, the chassis 901 pushes the baffle 1001 open to both sides. At this time, the baffle 1001 is opened by the slider 10. The 02 and the slide rail 1003 are parallel to each other in opposite directions. The second spring 1005 is compressed at this moment until the distance between the two baffles 1001 is sufficient for the charging pile to pass through. When the charging pile and the fixing device 9 pass through the baffle 1001 and reach the inside of the test chamber 11, the first motor 2 rotates 120°. At the same time, the disc 8 and the fixing device 9 stop rotating. The water spray test device 21 in the test chamber 11 is activated to simulate a rain scene and perform a waterproof test on the charging pile. After the specified time, the first motor 2 is activated, and the fixing device 9 continues to rotate with the disc 8. It passes through the automatic opening and closing isolation device 10 at the other end in the same way and reaches the inside of the drying chamber 12 for drying. The first motor 2 stops again to dry the charging pile on the placement tray 902. After the specified time, the automatic drying operation is completed. The first motor 2 is activated again to rotate 120° so that the charging pile returns to the loading chamber 7 and can be taken out.
