[0024] Furthermore, a first sensor 12 and a second sensor 13 are sequentially provided in the first water cylinder 4 and the second water cylinder 6 along their axial direction. The first sensor 12 is located at the upper limit position of the hydraulic liquid 7 to prevent the hydraulic liquid 7 from overflowing and causing damage to the device and affecting the ventilation efficiency; the second sensor 13 is located at the lower limit position of the hydraulic liquid 7 to ensure that the hydraulic liquid 7 is always maintained above the minimum liquid level, avoiding overheating and shutdown of the device due to insufficient hydraulic liquid 7, thereby ensuring the stable operation of the device; a third sensor 16 is provided on the top of the inner wall of the first water cylinder 4 and the second water cylinder 6, and the third sensor 16 is located at the highest position of the hydraulic liquid 7; the setting of the first sensor 12, the second sensor 13 and the third sensor 16 makes the device more automated and intelligent, thereby improving work efficiency.
