A liquor path structure having an air pressure flushing function, and an ultrasonic liquor aging system. A sub liquor control valve (J113) is provided at the outlet of a liquor inlet and outlet pipe; a high-pressure air input port is provided on an air discharge pipe; a manual air valve is provided on the high-pressure air input port; a medical air pump is movably connected to the high-pressure air input port; an air discharge valve (J102) and the sub liquor control valve (J113) are controlled to be closed, and high-pressure air within a preset pressure range is injected into a stainless steel aging barrel (J111) by means of the medical air pump; the sub liquor control valve (J113) is controlled to be opened, and residual liquor in the stainless steel aging barrel (J111) is instantaneously vaporized and is discharged by means of the liquor inlet and outlet pipe. By using the principle that a liquid is suddenly released and atomized after high pressure is applied, and then is discharged along with high-pressure gas, the residual liquor in a liquor path is quickly cleaned when an aged liquor needs to be replaced, and the residual liquor hung on a wall or other corners can be cleaned.
A: A sensor cleaning device (20) and method, a sensor recognition system and an autonomous vehicle (1). The sensor cleaning device (20) comprises a main control module (21), a high-pressure gas nozzle (22), and a high-pressure liquid nozzle (23). The main control module (21) is connected to the high-pressure gas nozzle (22) and the high-pressure liquid nozzle (23) and configured to control the high-pressure gas nozzle (22) and the high-pressure liquid nozzle (23). The high-pressure gas nozzle (22) and the high-pressure liquid nozzle (23) are fixedly provided on a sensor (10), and the high-pressure gas nozzle (22) is connected to a gas pump and configured to spray high-pressure gas to clean the sensor (10). The high-pressure liquid nozzle (23) is connected to a water storage tank and a liquid storage tank storing cleaning liquid, and configured to spray clean water or the cleaning liquid to clean the sensor (10). When the sensor (10) needs to be cleaned, the main control module (21) controls the high-pressure liquid nozzle (23) to spray out the cleaning liquid to clean stains, clean water is sprayed out for flushing, and high-pressure gas is sprayed out by means of the high-pressure gas nozzle (22), such that cleaning of the sensor (10) is completed, and the recognition accuracy of the sensor (10) is improved.
B: Disclosed are a system and method for storing a high pressure gas on the seabed, using a gas compressor (3) to compress and provide an uninterrupted supply of gas into a sealed gas tank (1) on the seabed via a gas inlet pipe (6). When the high pressure gas in the sealed gas tank (1) needs to be used, the sealed gas tank (1) releases the high pressure gas to an external energy conversion apparatus via a gas discharge pipe (7). An internal and external sensor transfer a pressure value to a controller for pressure comparison and for control of a lifting apparatus. When the high pressure gas is poured into the sealed gas tank (1), the lifting apparatus drives the sealed gas tank (1) to sink, and when the sealed gas tank (1) releases the high pressure gas to the outside, the lifting apparatus drives the sealed gas tank (1) to float upwards. When the sealed gas tank (1) is storing or discharging the high pressure gas, the internal and external pressure differential borne by the housing thereof is within the pressure range of the bearing capacity of the housing of the sealed gas tank. That is to say, the sealed gas tank (1) can admit more high pressure gas and does not need a relatively thick tank wall for support, making the costs of the sealed gas tank lower.
C: A pneumatic multi-stage pressurization device, comprising a drive cylinder (1), a drive piston (2) disposed in the drive cylinder (1), a multi-stage pressurization device (3) connected to the drive piston (2), and a filter (4) connected at the back end of the multi-stage pressurization device (3); the drive cylinder (1) comprises a drive cylinder sleeve (11), and a pressurized cylinder cap (12) and a cylinder seat (13) disposed at the two ends of the cylinder sleeve (11); the pressurized cylinder cap (12) and the cylinder seat (13) are connected to a reversing valve (5); disposed on the reversing valve (5) are an exhaust opening, a reversing pipe air inlet, a forward pipe air outlet, a reverse pipe air outlet, a high pressure pipe connector, and a gas input connector. The drive piston (2) moves to the pressurized cylinder cap (12) position, triggering a pressure reducing valve (16); the pressure reducing valve (16) discharges the pressure in a reversing cylinder; the reversing valve core moves; gas in a reverse pipe switches to an exhaust pipe to be released; and a forward pipe opens. The described actions realize reciprocating operation. The drive piston (2) drives a second stage pipe and a high pressure rod, thereby driving reciprocating operation of a first stage piston (32), a second stage piston (34) and a third stage piston (36).
D: An ultrasonic alcoholic beverage aging device, comprising an ultrasound generating unit, a containing unit, an alcoholic beverage holding unit, and an alcoholic beverage input and output operating unit. The ultrasound generating unit is used to generate a mechanical vibration. The mechanical vibration is transmitted to the alcoholic beverage holding unit via water in the containing unit so as to perform aging processing on an alcoholic beverage in the alcoholic beverage holding unit. The alcoholic beverage input and output operating unit is used to input the alcoholic beverage into the alcoholic beverage holding unit and output the liquid from the alcoholic beverage holding unit. The aging device is further provided with a control panel, and the control panel is provided with a alcoholic beverage input and output switch. When the alcoholic beverage input and output switch is in different positions, the alcoholic beverage input and output operating unit is controlled to perform an alcoholic beverage input or output operation.
