[0034] The cabinet 5 is installed on the outside of the mist-making structure 7 , and a blower 8 connected to the spray structure 4 is installed at the bottom of the cabinet 5 , and a host 6 is installed at the top of the cabinet 5 .
[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the spray structure 4 includes a spray pipe 401 fixed to the inside of the door frame 1, a nozzle 406 installed on the inside of the spray pipe 401, a three-way pipe 402 installed at the middle position of the spray pipe 401, a bellows 403 fixed to the top of the three-way pipe 402, an air duct 405 installed at the bottom of the bellows 403 and connected to the blower 8, and a mist inlet pipe 404 fixed to one side of the air duct 405, and a plurality of groups of nozzles 406 are installed on the inside of the spray pipe 401, and a plurality of groups of nozzles 406 are installed on the inside of the spray pipe 401. The interior is evenly spaced, and the mist-making structure 7 includes a casing 701 fixed inside the cabinet 5, a liquid storage tank 702 installed inside one side of the casing 701, a tank cover 703 threadedly connected to the top of the liquid storage tank 702, an oil pipe 709 installed at the bottom end of the casing 701 and connected to the liquid storage tank 702, a solenoid valve 704 fixed at the middle of the oil pipe 709, an oil pump 705 fixed on one side of the oil pipe 709, a heating box 706 installed inside the casing 701 and connected to the oil pump 705, a temperature-controlled heater 707 installed at the bottom end of the oil pump 705, and The air pump 708 is installed at the top of one side of the heating box 706 and is connected to the mist inlet pipe 404. By installing the device in the use position, the height of the door frame 1 is adjusted using the lifting structure 9, and the fog-making structure 7, the blower 8, the broadcast 2 and the laser projection lamp 3 are controlled by the host 6. The mist oil is injected into the liquid storage tank 702 by opening the tank cover 703. Then the host 6 controls the solenoid valve 704 and the oil pump 705 to open, so that the mist oil enters the interior of the heating box 706. The host 6 controls the temperature control heater 707 to heat the mist oil, so that the mist oil produces smoke. Then the air pump 708 The smoke is introduced into the interior of the mist inlet pipe 404, and the blower 8 is started to inject airflow into the interior of the air duct 405. Since the flow rate of the gas inside the air duct 405 is much greater than the flow rate of the gas inside the mist inlet pipe 404, the smoke inside the mist inlet pipe 404 passes through the interior of the air duct 405, and then passes through the bellows 403 and the three-way pipe 402 into the interior of the spray pipe 401, and is sprayed out by the nozzle 406. The laser projection lamp 3 is started to generate laser to illuminate the smoke, so that the laser is refracted under the action of the Tyndall effect and forms a visible virtual light curtain, which is used to remind the driver to drive carefully after passing through the light curtain.
[0036] like Figure 5As shown, as a preferred embodiment, on the basis of the above-mentioned manner, the lifting structure 9 further includes slide rails 901 fixed on both sides of the door frame 1, a fixed frame 905 sliding on the outside of the door frame 1, a slide groove 906 opened inside the fixed frame 905 and slidably connected to the slide rails 901, a rack 904 fixed inside one side of the fixed frame 905, a cam 903 rotatably connected to the bottom end of one side of the door frame 1, and a toothed plate 902 provided on one side of the cam 903 and meshingly connected to the rack 904. The door frame 1 is connected to the cam 903 through the tooth plate 902, and a sliding structure is formed between the tooth plate 902 and the fixed frame 905. By pulling the door frame 1, the door frame 1 drives the slide rail 901 to slide inside the slide groove 906, and the height of the door frame 1 is adjusted. The cam 903 is rotated to rotate and shorten the distance between the cam 903 and the door frame 1. At the same time, the cam 903 squeezes the tooth plate 902 and the rack 904 to fit together, and locks it in the position between the door frame 1 and the fixed frame 905 to fix the height of the door frame 1.
[0037] Specifically, when the virtual door curtain of the tunnel is used: by installing the device at the use position, using the lifting structure 9 to adjust the height of the door frame 1, the fog-making structure 7, the blower 8, the broadcast 2 and the laser projection lamp 3 are controlled by the host 6, and the smoke oil is injected into the liquid storage tank 702 by opening the tank cover 703. Then the host 6 controls the solenoid valve 704 and the oil pump 705 to open, so that the smoke oil enters the interior of the heating box 706. The host 6 controls the temperature control heater 707 to heat the smoke oil, so that the smoke oil generates smoke, and then the air pump 708 guides the smoke into the mist pipe Inside 404, the blower 8 is started to inject air into the air duct 405. Since the flow rate of the gas inside the air duct 405 is much greater than the flow rate of the gas inside the mist inlet pipe 404, the smoke inside the mist inlet pipe 404 passes through the inside of the air duct 405, and then passes through the bellows 403 and the tee pipe 402 into the inside of the spray pipe 401, and is sprayed out by the nozzle 406. The laser projection lamp 3 is started to generate laser light to illuminate the smoke, so that the laser light is refracted by the Tyndall effect and forms a visual virtual light curtain, which is used to remind the driver to drive carefully after passing through the light curtain;
[0038] By pulling the door frame 1, the door frame 1 drives the slide rail 901 to slide inside the slide groove 906, adjust the height of the door frame 1, and rotate the cam 903 to rotate and shorten the distance between the cam 903 and the door frame 1. At the same time, the cam 903 squeezes the gear plate 902 to fit the rack 904, and locks it in the position between the door frame 1 and the fixed frame 905 to fix the height of the door frame 1.
[0039] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention.
