[0020] Embodiment 1

[0021] A liftable single-sided spraying device, comprising two lifting plates 1. Lifting frames are installed at the bottoms of the two lifting plates 1. A sliding plate 2 is installed between the tops of the lifting frames. A chute 3 is provided on the sliding plate 2. A motor 401 is arranged at the bottom of one end of the chute 3. A rotating rod 402 is pivotally connected to the top of the other end of the chute 3. A transmission belt 4 is sleeved between the motor shaft of the motor 401 and the rotating rod 402. A locking block 501 is fixed on the transmission belt 4. The locking block 501 is connected to a fixing rod 5. A connecting rod 6 is arranged on the fixing rod 5. The connecting rod 6 is connected to a first water pipe 7. A number of spraying head devices are arranged on the first water pipe 7. The spraying head device includes a second water pipe 8 communicated with the first water pipe 7. The second water pipe 8 is communicated with a first hose 9. The first hose 9 is communicated with a spraying head 10. A limiting block 12 is installed below the spraying head 10. A limiting chute 13 is provided on the limiting block 12. A limiting slider 14 is slidably connected in the limiting chute 13. The limiting slider 14 is pivotally connected to one end of an electric push rod 11. The other end of the electric push rod 11 is installed at the bottom of the second water pipe 8. A solenoid valve 15 is arranged at the bottom of the first water pipe 7. The first water pipe 7 is communicated with a second hose 16 through the solenoid valve 15. The second hose 16 is communicated with a water pump 17. The water pump 17 is communicated with a water storage device. The horizontal height can be controlled by the lifting frame. The change of the horizontal position can be realized by the motor 401 driving the transmission belt 4. The spraying angle can be adjusted by the electric push rod 11. During use, the height, horizontal position and spraying angle can be adjusted according to the required test environment. After reaching the required conditions, the test can be carried out. The arrangement of multiple spraying head devices can simultaneously perform spraying tests on the top and side of the device under test.

[0022] The lifting frame, the motor 401, the electric push rod 11 and the solenoid valve 15 are all electrically connected to the main control device. The present utility model introduces a remote control system. A main control room is set in the test site. The main control room is separated from the test room.
