The other end of the connecting pipe 14 is connected to the water spray disc 9. One end of the connecting pipe 14 connected to the water spray disc 9 is an elastic telescopic hose. A driven gear 15 is fixed to the outer wall of the rotating cylinder 7. A driving gear 11 is meshed with one side of the driven gear 15. A motor 12 is fixed to the outer wall of the shell 1, and the output shaft of the motor 12 is connected to the driving gear 11.

[0029] During the inspection, the charging head 5 is fixed inside the fixed cover 3 through the fixing component 4, and the charging gun 6 is connected to the charging head 5 to simulate the state of the charging head during charging. Then the water pump 13 inputs the water at the bottom of the shell 1 through the connecting pipe 14 into the water spray tray 9 for spraying, simulating the rainy day environment, and conducts the inspection. After the inspection is completed, the charging head 5 is taken out to check whether water has entered the charging head 5. Since there will be a certain angle between the rainwater and the charging head 5 in the rainy day environment, the driving gear 11 is driven by the motor 12 to rotate, so that the position of the connecting frame 8 changes and the electric telescopic rod 10 changes the inclination angle of the water spray tray 9, so that the water droplets sprayed from the water spray tray 9 are relatively inclined with the charging head 5, so that the device can simulate the real rainy day environment more realistically.

[0030] By providing a shell 1, a fixed cover 3, a fixed assembly 4, a charging head 5, a charging gun 6, a rotating cylinder 7, a connecting frame 8, a water spray plate 9, a water pump 13 and a connecting pipe 14, the state of the charging head 5 when charging in a rainy environment is simulated, and the waterproof performance of the connection between the charging head 5 and the charging gun 6 when the charging gun 5 is connected to the charging head 6 can be tested.

[0032] Example 2

[0033] A charging head waterproof detection device, based on the embodiment 1, this embodiment makes the following improvements, such as Figure 6As shown, the fixing assembly 4 includes a fixing ring 16 connected to the inner wall of the fixing cover 3 and a plurality of protective boxes 17 fixed to the inner wall of the fixing ring 16, the inner wall of the fixing ring 16 is rotatably connected with a plurality of threaded rods 18, the threaded rods 18 are located inside the protective box 17, the outer wall of the threaded rod 18 is threadedly connected with a fixing cylinder 19, the fixing cylinder 19 is slidably matched with the protective box 17, one side of the fixing cylinder 19 is provided with a bolt 20 connected with the charging head 5, the top of the threaded rod 18 is connected with a driving gear 22, the outer wall of the fixing ring 16 is connected with a rotating ring 21 for damping rotation, and the outer wall of one side of the rotating ring 21 is fixed with a driven gear 23 that is transmission-engaged with the driving gear 22.

[0034] When fixing the charging head 5, place the charging head 5 between multiple fixing cylinders 19, rotate the rotating ring 21, and rotate the protective box 17 through the transmission of the driven gear 23 and the driving gear 22, so that multiple fixing cylinders 19 are simultaneously moved closer to the charging head 5. When the bolt 20 on one side of the fixing cylinder 19 is aligned with the through hole on the charging head 5, insert the bolt 20 into the through hole and tighten it with a nut to fix the charging head 5.

[0035] By setting the rotating ring 21, the driving gear 22 and the driven gear 23, the rotating ring 21 can be rotated to make multiple fixing cylinders 19 move closer to the charging head 5 at the same time, and the position of the bolt 20 can be adjusted so that it can fix charging heads 5 of different specifications, which is convenient to operate.

[0036] Working principle: During the inspection, the charging head 5 is placed between multiple fixed cylinders 19, and the rotating ring 21 is rotated. The protection box 17 is rotated through the transmission of the driven gear 23 and the driving gear 22, so that multiple fixed cylinders 19 are simultaneously moved closer to the charging head 5. When the bolt 20 on one side of the fixed cylinder 19 is aligned with the through hole on the charging head 5, the bolt 20 is inserted into the through hole, and the nut is tightened to fix the charging head 5. Then the charging gun 6 is connected to the charging head 5 to simulate the state of the charging head during charging. Then the water pump 13 inputs the water at the bottom of the shell 1 through the connecting pipe 14 into the water spray plate 9 to spray it out, simulating the rainy environment for inspection. After the inspection is completed, the charging head 5 is taken out to check whether water has entered the charging head 5. Because there will be a certain angle between the rainwater and the charging head 5 in the rainy environment, the motor 12 drives the driving gear 11 to rotate, so that the position of the connecting frame 8 changes and the electric telescopic rod 10 changes the inclination angle of the water spray plate 9, so that the water droplets sprayed from the water spray plate 9 are relatively inclined with the charging head 5, so that the device simulates the actual rainy environment more realistically.
